Description

Vehicle rear structure and vehicle Technical Field The present invention relates to the technical field of vehicles, and more particularly, to a vehicle rear structure and a vehicle. Background With the rapid development and progress of society, vehicles have become an indispensable transportation means in people's daily lives. In a vehicle, a plurality of decorative plates are usually arranged to shield the white body of the vehicle and the internal structures such as an electronic module, so that the vehicle is decorated, a user is particularly concerned with matching among the decorative plates of the vehicle, and the good appearance greatly determines the selection of consumers. Automotive interior trim components, which are an important component of a vehicle and are also an important part of the overall design and skill level of the vehicle, do not play a significant role. For the rear of the vehicle, the design of the interior trim piece also involves the problem of matching between the C-pillar trim panel and the trunk side trim panel. Generally, a felt material is adopted for a trunk side decoration plate of a vehicle, a plastic material is adopted for a C column decoration plate, and the felt material is soft, so that the trunk side decoration plate and the C column decoration plate can easily generate gaps at the lap joint position of the trunk side decoration plate and the C column decoration plate due to deformation of the trunk side decoration plate or deformation of the trunk side decoration plate due to external force in the long-term use process of a customer, the overall effect of the interior decoration at the rear part of the vehicle can be damaged, the use feeling of the customer is influenced, and the customer satisfaction degree is reduced. Referring to fig. 1 and 2, the side trim 2 of the luggage case of fig. 1 is connected with the side trim 1 of the C-pillar by the push-in buckle 3, and in fig. 2, the side trim 20 of the luggage case is installed by welding the stud 30 on the metal plate 40 of the car body in advance, then installing the side trim 10 of the C-pillar, and finally fixing the side trim 20 of the luggage case and the side trim 10 of the C-pillar on the metal plate 40 of the car body by the nut 31. Both of these prior art techniques require the assembly worker to additionally take fasteners on the assembly line, affecting the assembly tact. Disclosure of Invention The invention aims to provide a vehicle rear structure and a vehicle, wherein the vehicle rear structure is directly connected with a side decorative plate of a trunk by forming a clamping structure by a C-pillar decorative plate, so that the time for a general assembly worker to additionally take a fastener is shortened, the use of the fastener is saved, the assembly efficiency of a production line is improved, and the material cost of the vehicle is reduced. To this end, a first aspect of the present invention provides a vehicle rear structure, a C-pillar trim including a fitting portion, a rotation shaft portion extending from the fitting portion, and a clamping portion extending from the rotation shaft portion, and a trunk-side trim including a lap portion at least partially fitted to the fitting portion and a relief hole provided on the lap portion, wherein the clamping portion is configured to be rotatable about the rotation shaft portion, compresses the lap portion between the clamping portion and the fitting portion after rotation, and clamps the fitting portion through the relief hole. The present invention may further include any one or more of the following optional forms according to the above technical idea. In some alternatives, the attachment portion includes a clamping through hole, the clamping portion includes a sheet-shaped body and a clamping unit protruding from the body, wherein the clamping portion is configured to cause the clamping unit to penetrate and clamp into the clamping through hole after rotating about the rotating shaft portion. In some alternatives, the shaft portion is configured to have a flexible sheet-like structure. In some alternatives, the thickness of the shaft portion is less than the thickness of the body of the clip portion. In some alternatives, the clamping unit includes a step configured to clamp onto a face of the conforming portion facing away from the overlap portion after the clamping unit is threaded into the clamping through hole. In some optional forms, the dodge hole and the clamping through hole are rectangular holes, and the size of the dodge hole is larger than that of the clamping through hole. In some alternatives, the C-pillar trim is provided as an integrally molded plastic piece. In some alternatives, the luggage side fascia is made from a felt-like material by a molding process. A second aspect of the invention provides a vehicle comprising a vehicle rear structure according to the invention. Compared with the prior art, the vehicle rear structu
