Abstract

A support system (140) for supporting an elongated structure (130) is described. The system comprises a first holding element (201) and a second holding element (202). The first element (201) is characterized by a receiving portion (211), and a locking portion (212) having a locking member (220), a mating recess (221), and a groove (240) spanning the two portions. The grooves (240) have different profiles in the two parts. The second element (202) has an edge flange (250) and a beam (230) with cantilevered hooks (231). The edge flange (250) fits into the groove (240) and the hook (231) fits into the recess (221) of the first element (201). The first and second retaining elements together enclose the structure (130). The second element (202) slides from the receiving portion to the locking portion, wherein the edge flange (250) and the hook (231) are aligned with corresponding features of the first element (201).

Description

Support system for supporting elongated structures of batteries Technical Field This document relates to a support system for supporting an elongated structure such as a cable, tube or hose, so as to fix the elongated structure relative to a base structure by mounting the support system directly or indirectly to the base structure. Background It is often desirable to releasably secure cables, bus bars or other elongated structures such as pipes or hoses relative to a base or base structure. Fixing the cable to a moving object, such as a vehicle, may present challenges beyond conventional ones, as vehicles typically move during operation and/or are subjected to vibrations, acceleration/deceleration/lateral forces, possible airflow, etc. during cornering. Shifting of the cable to an undesired/dangerous position or creating stress on the cable is undesired and may present a very dangerous situation. In fuel propelled vehicles, electrical cables are often used to connect, for example, an electrical generator to a battery in the vehicle, and/or to perform other various functions of the vehicle, such as lights/horns, steering servos (steering servos), etc. Thus, a damaged or failed cable will immediately create a dangerous situation on the vehicle, forcing the driver to immediately stop driving. Electric vehicles typically use a high voltage cable to power an electric engine from a battery. It is important to fix the cable to avoid potentially fatal accidents, for example if the high voltage cable is damaged, e.g. pressed by a hatch or door in the vehicle, or suspended into some moving/rotating elements in the vehicle. At the same time, it is desirable to facilitate easy installation of the elongated structure to a desired location, as it is necessary to ensure that the elongated structure is fixed, and/or to facilitate subsequent replacement of the elongated structure, for example during maintenance or retrofitting of the vehicle, or for example during battery replacement. Sometimes it is desirable to install the cable/elongated structure in a very narrow space with very limited clearance around the cable/elongated structure. This typically occurs in a battery pack supporting a busbar. It is therefore desirable to find a solution to these problems associated with releasable securement of elongated structures, particularly on vehicles. Disclosure of Invention It is therefore an object of the present invention to solve at least some of the above problems and to improve traffic safety by supporting an elongated structure in a vehicle. According to a first aspect of the invention, this object is achieved by a support system for supporting an elongated structure. The elongated structure may comprise busbar, cable, pipe, hose or similar elements. The system includes a first retaining element and a second retaining element configured to enclose an elongated structure with the first retaining element. The first retaining element includes a receiving portion. Further, the first retaining element comprises a locking portion comprising a locking member and a mating recess (mating depression). In addition, the first retaining element includes a groove extending over the receiving portion and the locking portion of the first retaining element, wherein the groove includes a first profile at the receiving portion and a second profile at the locking portion. The second retaining element includes an edge flange (rim) configured to enter the groove at the receiving portion of the first retaining element. The second retaining element further includes a beam having a cantilevered protruding hook, wherein the protruding hook is configured to enter the mating recess of the first retaining element when the second retaining element is entered into the receiving portion of the first retaining element. The second retaining element is configured to enclose the elongated structure with the first retaining element when the edge flange of the second retaining element is placed in the groove at the receiving portion of the first retaining element and the cantilevered protruding hook enters the mating recess of the first retaining element. The second retaining element is slidable from the receiving portion into the locking portion of the first retaining element, allowing the edge flange of the second retaining element to slide into the second profile of the groove at the locking portion of the first retaining element, and the cantilevered protruding hook engages with the locking member of the locking portion of the first retaining element. The support system can be easily assembled/disassembled by an operator in a short time without any tools. Due to the concept of two separate holding elements, the support system can also be installed in a narrow space with very small gaps around the elongated structure being supported. The elongated structure is held in place in a secure manner while allowing thermal expansion/contraction of the elongated st
