[0034] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] The utility model discloses a switching device, such as Figure 1 , Figure 2 and Figure 8 As shown, the adapter device of this embodiment includes a fixing seat 100, a protective member 200 and an adapter 300. The fixing seat 100 is used to fix the adapter device to an external structure. The protective member 200 defines a protective cavity 210 with two open ends. The protective member 200 is connected to the fixing seat 100. The adapter 300 is connected to the fixing seat 100 and is located in the protective cavity 210. The adapter 300 is provided with an adapter 310, and the lead wire on the adapter 310 can extend from the open end of the protective cavity 210. It can be understood that in the actual assembly process, the adapter 300 is first fixed to the fixing seat 100, and then the protective member 200 is installed on the fixing seat 100. After the adapter 300 is connected, it is protected from rain and dust, reducing the risk of short circuit, which is conducive to improving the reliability of the electrical components of the electric vehicle.

[0036] Optionally, after the adapter 300 is connected to the wires, the open end of the protective cavity 210 for leading out the lead wires can be tightened using structures such as cable ties and tape, placing the entire adapter 300 in a relatively sealed space, which can further protect it from rain and dust erosion, reduce the risk of short circuits, and be more conducive to improving the reliability of the electrical components of the electric vehicle.

[0037] Optionally, the protective member 200 is a rubber member. Thus, it can have a better protective effect. Of course, in other embodiments of the present utility model, the protective member 200 can also be made of other materials according to actual needs, and is not limited to the rubber material of this embodiment.

[0038] refer to Figure 3-Figure 4 As shown, the fixing seat 100 has a fixing cavity 110 which is open toward the protective member 200, and the adapter 300 is detachably connected to the fixing cavity 110. It can be understood that the fixing seat 100 is provided with a fixing cavity 110 for accommodating the adapter 300. After installation, the adapter 300 is accommodated in the fixing cavity 110, which can play a certain protective role on the adapter 300, avoid damage to the adapter 310 due to external force, and help improve the reliability of the electrical components of the electric vehicle.

[0039] Optional, reference Figure 6 As shown, the inner side wall of the fixed cavity 110 is provided with a fixed clamping protrusion 120, and the fixed clamping protrusion 120 is spaced apart from the top wall of the fixed cavity 110, and the adapter 300 is clamped between the fixed clamping protrusion 120 and the top wall of the fixed cavity 110. It can be understood that in the actual installation process, it is only necessary to clamp the adapter 300 between the fixed clamping protrusion 120 and the top wall of the fixed cavity 110 so that the bottom wall of the adapter 300 stops against the fixed clamping protrusion 120. Therefore, in the assembly process, it is not necessary to assemble the adapter 300 with connecting parts such as screws, which simplifies the structure of the fixing seat 100 and the adapter 300 on the one hand, and facilitates the installation and disassembly of the adapter 300 on the other hand.

[0040] Of course, in other embodiments of the present invention, the connection method between the adapter 300 and the fixing seat 100 can also be a detachable connection method such as screw connection according to actual needs, or a non-detachable connection method such as bonding can be used.

[0041] refer to Figure 1 and Figure 4As shown, one end of the protective member 200 is sleeved on the outer peripheral wall of the fixing seat 100 and connected to the fixing seat 100. It is understandable that one end of the protective member 200 is directly sleeved and fixed on the outer peripheral wall of the fixing seat 100, which facilitates the installation of the protective member 200 on the fixing seat 100, thereby facilitating assembly and helping to improve user satisfaction. In an embodiment of the utility model, there can be multiple specific connection methods between the protective member 200 and the fixing seat 100. In a specific embodiment, the protective member 200 is fixed to the fixing seat 100 by a cable tie. In the actual assembly process, one end of the protective member 200 is sleeved on the outer peripheral wall of the fixing seat 100, and then it is tightened with a cable tie. In another specific embodiment, one end of the protective member 200 is provided with a retractable belt 220, and the retractable belt 220 is pressed against the outer peripheral wall of the fixing seat 100 to fix the protective member 200 to the fixing seat 100. In the actual assembly process, one end of the protective member 200 is first sleeved on the outer peripheral wall of the fixing seat 100, and then the retractable belt 220 is tightened. Compared with the technical solution of tightening with a cable tie, the structure of the retractable belt 220 can more conveniently realize the installation and removal of the protective member 200. In another specific embodiment, the inner peripheral wall of the protective member 200 is provided with an adhesive layer, and the adhesive layer is bonded to the outer peripheral wall of the fixing seat 100. In the actual assembly process, it is only necessary to sleeve one end of the protective member 200 on the outer peripheral wall of the fixing seat 100, and then make the inner peripheral wall of the protective member 200 bonded to the fixing seat 100. Compared with the fixing methods of the cable tie and the retractable belt 220, the adhesive fixation can more securely fix the protective member 200 to the fixing seat 100, avoiding the phenomenon of the protective member 200 falling off.

[0042] Further, refer to Figure 5 and Figure 7 As shown, the outer peripheral wall of the fixing seat 100 has a fixing groove 130 extending along the contour direction thereof, and the fixing groove 130 is used to accommodate the telescopic belt 220 or the cable tie. It is understandable that after the connection is completed, the instability of the telescopic belt 220 and the cable tie can easily cause the protective member 200 to fall off relative to the fixing seat 100. In this embodiment, by providing the fixing groove 130 on the outer peripheral wall of the fixing seat 100, the telescopic belt 220 and the cable tie can be limited to a certain range, and the stability of the telescopic belt 220 and the cable tie can be improved, so that the protective member 200 is firmly fixed to the fixing seat 100, and the protective member 200 is prevented from falling off.

[0043] refer to Figure 5As shown, optionally, the peripheral wall of the fixing seat 100 has a first flange 140 and a second flange 150 extending along the contour direction thereof, the first flange 140 and the second flange 150 are arranged at intervals, and the space between the first flange 140 and the second flange 150 constitutes the fixing groove 130. It can be understood that by forming the fixing groove 130 by arranging the first flange 140 and the second flange 150 instead of directly machining the fixing groove 130 on the peripheral wall of the fixing seat 100, the deformation phenomenon caused by the excessively thin wall thickness of the fixing seat 100 can be avoided while ensuring the restrictive effect on the telescopic band 220 and the cable tie.

[0044] refer to Figure 5 As shown, optionally, the first flange 140 has a plurality of first notches 141 spaced apart along the contour line of the outer peripheral wall of the fixing seat 100. It is understandable that, compared with the complete first flange 140, the first flange 140 is divided into multiple sections by providing a plurality of first notches 141, and the first notches 141 can play a certain clamping role, restricting part of the protective member 200 within the first notches 141, thereby improving the connection stability between the protective member 200 and the fixing seat 100. In the embodiment of the utility model, the shape, number and arrangement of the first notches 141 can be selected according to actual needs, and the shape, number and arrangement of the first notches 141 are not limited here.

[0045] refer to Figure 5 As shown, the second flange 150 has a plurality of second notches 151 spaced apart along the contour line of the outer peripheral wall of the fixing seat 100. It is understandable that, compared with the complete second flange 150, the second flange 150 is divided into multiple sections by providing a plurality of second notches 151, and the second notches 151 can play a certain clamping role, restricting part of the protective member 200 within the second notches 151, thereby improving the connection stability between the protective member 200 and the fixing seat 100. In the embodiment of the utility model, the shape, number and arrangement of the second notches 151 can be selected according to actual needs, and the shape, number and arrangement of the second notches 151 are not limited here.

[0046] It should be noted that, in the embodiment of the present invention, the cross-sectional shape, thickness and other parameters of the first flange 140 and the second flange 150 can be selected according to actual needs.

[0047] refer to Figure 5As shown, a fixing clamp 160 is provided on the outer peripheral wall of the fixing base 100, and the fixing clamp 160 is used to be clamped to the external structure. It can be understood that the entire adapter can be easily installed on a tubular external structure through the fixing clamp 160, thereby conveniently realizing the installation and removal of the adapter. Of course, in other embodiments of the utility model, a fixing ear can also be provided on the outer peripheral wall of the fixing base 100, and connected to the external structure by screws penetrated on the fixing ear. In the embodiment of the utility model, the connection method between the fixing base 100 and the external structure can be adjusted according to actual needs.

[0048] The utility model also discloses an electric vehicle, including a vehicle body and the above-mentioned adapter, wherein the vehicle body is provided with electronic components and a controller, and the electronic components and the controller are electrically connected to the adapter 300. Due to the above-mentioned adapter, the electric vehicle is not only convenient to wire, the wiring harness is neat, but also has a low short circuit risk and high reliability of the electrical components.
