Detailed Description of the Embodiment

[0036] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, rather than limiting the utility model. In addition, it should be noted that for the sake of description, only parts related to the utility model are shown in the drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] like Figures 1-6 As shown, an embodiment of the utility model provides a switching device, a power supply device and a vehicle.

[0039] like Figure 1 As shown, the switching device 5 provided in the embodiment of the utility model includes:

[0040] The transfer bar 1 includes a first transfer bar 3 and a second transfer bar 4; and

[0041] The connecting member 2 is fixedly connected to at least a portion of the first adapter row 3, and the connecting member 2 is fixedly connected to at least a portion of the second adapter row 4.

[0042] In the fixed connection area, the connecting member 2 is insulated from the first adapter bar 3 ; and / or the connecting member 2 is insulated from the second adapter bar 4 .

[0043] In some embodiments, the transfer bar 1 includes a first transfer bar 3 and a second transfer bar 4, wherein the first transfer bar 3 can be a positive copper bar and the second transfer bar can be a negative copper bar, or the first transfer bar 3 can be a negative copper bar and the second transfer bar can be a positive copper bar.

[0044] In some embodiments, the connector 2 is fixedly connected to the first adapter bar 3 and the second adapter bar 4 respectively, so that the connector 2, the first adapter bar 3 and the second adapter bar 4 are constructed as a whole, that is, the adapter device 5. Compared with the prior art, in the actual assembly process, the process of assembling the connector 2, the first adapter bar 3 and the second adapter bar 4 is omitted, thereby improving the assembly efficiency.

[0045] In some embodiments, the connector 2 and the first adapter bar 3 may be partially fixedly connected or entirely fixedly connected; the connector 2 and the second adapter bar 4 may be partially fixedly connected or entirely fixedly connected.

[0046] In some embodiments, the connector 2 is insulated from the fixed connection area of ​​the first adapter bar 3 and / or the second adapter bar 4. The purpose of the insulation is to prevent the first adapter bar 3 and the second adapter bar 4 from being electrically connected, thereby preventing a short circuit from causing a safety hazard.

[0047] The connecting member 2 and at least a portion of the first adapter row 3 are plastic molded to be fixedly connected; and / or, the connecting member 2 and at least a portion of the second adapter row 4 are plastic molded to be fixedly connected.

[0048] In some embodiments, the connecting member 2 is fixedly connected to at least a part of the first adapter row 3 and / or at least a part of the second adapter row 4 by a plastic molding process. The plastic molding process may include, but is not limited to: injection molding process, blow molding process, etc.

[0049] In some embodiments, at least a part of the connecting member 2 and the first adapter row 3 are fixedly connected by an injection molding process; and / or, at least a part of the connecting member 2 and the second adapter row 4 are fixedly connected by an injection molding process.

[0050] In some embodiments, the structure formed by the injection molding process is the connecting member 2, that is, the connecting member 2 is a plastic part made by the injection molding process, and its material may include, but is not limited to: common materials for injection molding processes such as PP, ABS, PE, etc.

[0051] The connecting member 2 is directly insulated or indirectly insulated from the first adapter row 3; and / or, the connecting member 2 is directly insulated or indirectly insulated from the second adapter row 4.

[0052] In some embodiments, when the material of the connecting member 2 is an insulating material, the connecting member 2 is directly insulated from the first adapter row 3; when the material of the connecting member 2 is a non-insulating material, in order to ensure that the connecting member 2 and the first adapter row 3 are in an insulating state, an additional insulating structure needs to be provided between the connecting member 2 and the first adapter row 3 to insulate the connecting member 2 from the first adapter row 3. And / or, when the material of the connecting member 2 is an insulating material, the connecting member 2 is directly insulated from the second adapter row 4; when the material of the connecting member 2 is a non-insulating material, in order to ensure that the connecting member 2 and the second adapter row 4 are in an insulating state, an additional insulating structure needs to be provided between the connecting member 2 and the second adapter row 4 to insulate the connecting member 2 from the second adapter row 4.

[0053] In some embodiments, the insulating structure may be a common insulating material, which may include, but is not limited to: PVC, PTFE, rubber, etc.

[0054] In some embodiments, the shape of the insulating structure may include, but is not limited to: regular shapes (circular, rectangular, triangular, etc.), irregular shapes.

[0055] The first adapter row 3 and the second adapter row 4 are arranged at intervals.

[0056] In some embodiments, in order to ensure that the first adapter row 3 and the second adapter row 4 are not short-circuited due to direct connection, a certain distance needs to be reserved when arranging the first adapter row 3 and the second adapter row 4.

[0057] In some embodiments, the distance reserved between the first adapter row 3 and the second adapter row 4 is filled with the connecting member 2 to prevent the first adapter row 3 and the second adapter row 4 from being directly connected.

[0058] In some embodiments, the connecting member 2 may have a uniform wall thickness, that is, all characteristic wall thicknesses on the connecting member 2 body are the same.

[0059] In some embodiments, the connector 2 may have partially equal wall thickness, that is, the features on the connector 2 body may allow for multiple sets of wall thickness values. The specific wall thickness values ​​may be flexibly set according to design requirements and usage requirements, and will not be elaborated here.

[0060] A groove structure is provided in a partial area of ​​the connecting member 2 between the first adapter row 3 and the second adapter row 4 .

[0061] In some embodiments, in order to avoid short circuit caused by mutual connection between the first transfer row 3 and the second transfer row 4, a certain distance needs to be reserved between the first transfer row 3 and the second transfer row 4, because the first transfer row 3 and the second transfer row 4 are connected by the connector 2, when the distance between the first transfer row 3 and the second transfer row 4 is greater than 2 times the minimum wall thickness of the connector 2, the connector 2 can form a groove structure in a partial area between the first transfer row 3 and the second transfer row 4. The groove structure area has a smaller wall thickness of the connector 2 and can accommodate air for air circulation, so it can have a heat dissipation effect on the first transfer row 3 and the second transfer row 4.

[0062] like Figure 3 As shown, the adapter device 5 further includes a limiting bracket 7, at least part of which is disposed between the first adapter row 3 and the second adapter row 4. The limiting bracket 7 is used to keep a fixed distance between the first adapter row 3 and the second adapter row 4.

[0063] In some embodiments, since the first transfer row 3 and the second transfer row 4 are fixedly connected together by a plastic molding process, during the process of plastic injection in the mold, the liquid plastic material will impact the first transfer row 3 and / or the second transfer row 4, thereby causing the first transfer row 3 and / or the second transfer row 4 to deform, thereby causing a change in the fixed spacing set between the first transfer row 3 and the second transfer row 4. In order to solve this problem, the transfer device 5 also includes a limiting bracket 7, at least part of which is arranged between the first transfer row 3 and / or the second transfer row 4, so as to maintain a fixed spacing between the first transfer row 3 and the second transfer row 4.

[0064] In some embodiments, there are multiple limiting brackets 7 , and the multiple limiting brackets 7 can be arranged at intervals between the first adapter row 3 and the second adapter row 4 .

[0065] In some embodiments, there are multiple limiting brackets 7 , and the multiple limiting brackets 7 can be sequentially connected and arranged between the first adapter row 3 and the second adapter row 4 .

[0066] In some embodiments, a plurality of limiting brackets 7 are arranged on the first transfer row 3, and no limiting brackets 7 are arranged on the second transfer row 4; or,

[0067] A plurality of limiting brackets 7 are arranged on the second transfer row 4, and no limiting brackets 7 are arranged on the first transfer row 3; or,

[0068] Some of the plurality of limit brackets 7 are arranged on the first transfer row 3, and the other limit brackets 7 are arranged on the second transfer row 4. For example, when the total number of limit brackets 7 is 5, one limit bracket 7 can be arranged on the first transfer row 3, and four limit brackets 7 can be arranged on the second transfer row 4. Only one embodiment is cited here, and more embodiments are not described one by one.

[0080] In some embodiments, the connection portion 12 is flexibly connected to the body 11 so that there is a certain assembly tolerance when the connection portion 12 is connected to the power distribution device.

[0081] Second, as Figure 5 As shown, the utility model provides a power supply device 10, including the above-mentioned switching device 5.

[0082] In some embodiments, the adapter 5 is installed on the power supply device 10 and serves as an interface between the power supply device 10 and external equipment.
