Description

Switching Device and Vehicle The present disclosure relates to a switching device and a vehicle. Japanese Patent Publication No. 2021-156234 discloses a heat circuit in which a heat medium circulates. The heat circuit is provided with a switching valve that switches the flow path of the heat medium. FIG. 1 is a first side view showing a vehicle equipped with a conversion device according to one embodiment. FIG. 2 is a second side view showing a vehicle equipped with a conversion device according to one embodiment. FIG. 3 is a perspective view showing the configuration of a switching device according to one embodiment. FIG. 4 is a perspective view showing an actuator and a spool valve of a switching device according to one embodiment. FIG. 5 is a front view showing the configuration of the body of the case of a switching device according to one embodiment. FIG. 6 is a front view showing the configuration of the cover of the case of a switching device according to one embodiment. FIG. 7 is a cross-sectional view showing the configuration of the load vicinity of a switching device according to one embodiment. FIG. 8 is a plan view of the rod and cylinder of a switching device according to one embodiment, viewed from the Z2 side. Figure 9 is a magnified view of the area near the lip seal in Figure 7. FIG. 10 is a schematic side view showing a switching device according to a modified example of one embodiment. Embodiments of the present disclosure will be described with reference to the drawings. In addition, in the drawings referenced below, identical or equivalent components are given the same number. FIG. 1 is a side view of a vehicle (1) equipped with a switching device (100) according to the present embodiment. Furthermore, the use of the switching device (100) is not limited to vehicle use. Also, in this specification, the Z direction is defined as the up-down direction. Specifically, the Z1 direction is upward, and the Z2 direction is downward. Also, the X direction and the Y direction are each directions orthogonal to the Z direction. The X direction and the Y direction are orthogonal to each other in a plane orthogonal to the Z direction. The X1 direction and the X2 direction are defined as the vehicle front and vehicle rear, respectively. The Y1 direction and the Y2 direction are defined as the vehicle left and vehicle right, respectively. Also, the Z direction is an example of the "up-down direction" and "axial direction" of this disclosure. The vehicle (1) is equipped with a vehicle body (2), a drive unit (3), and a plurality (4) of wheels (4) in addition to a conversion device (100). Examples of the vehicle (1) include a hybrid electric vehicle, a plug-in hybrid electric vehicle, and a battery electric vehicle. The vehicle body (2) accommodates a switching device (100) and a driving device (3). In the vehicle body (2), a space S1 in which the switching device (100) is accommodated and a space S2 in which the driving device (3) is accommodated are formed. Space S1 and space S2 may be partitioned (separated). Additionally, space S1 is an example of a “accommodating space” of the present disclosure. The vehicle body (2) includes a bonnet (2a). The bonnet (2a) covers space S1 from above. The bonnet (2a) is openable. FIG. 1 is a drawing showing the bonnet (2a) in a closed state, and FIG. 2 is a drawing showing the bonnet (2a) in an open state. When the bonnet (2a) is opened, space S1 is exposed. By doing so, the user of the vehicle (1) can access the switching device (100) when the bonnet (2a) is opened. In addition, the bonnet (2a) is an example of the "upper surface" of the present disclosure. Referring again to FIG. 1, the driving device (3) is a device that generates driving force for the vehicle body (2). The driving device (3) may be a device that integrates (packages) components such as gears, motors, and inverters into one. Additionally, the driving device (3) may be a transaxle composed of a transmission and a differential gear. The switching device (100) is positioned opposite the bonnet (2a) in the Z direction. In other words, the switching device (100) is positioned so that no intervening material is intervened between it and the bonnet (2a). The upper portion (101) of the switching device (100) may be positioned along the bonnet (2a). By doing so, when the bonnet (2a) is open, the user, etc. can easily access the switching device (100). The switching device (100) is positioned on the Z1 side relative to the driving device (3). Specifically, the lower part (102) of the switching device (100) is positioned on the Z1 side relative to the upper part (3a) of the driving device (3). Additionally, the switching device (100) may be positioned in a location that overlaps with the driving device (3) in the Z direction. Accordingly, compared to the case where the switching device (100) is positioned on the Z2 side rather than the driving device (3), the user, etc. can easily access the switching device
