[0040] Among them, Figure 1 a reference direction coordinate system for the embodiments of the present invention is given. The following will describe the embodiments of the present invention in combination with Figure 1 the directions shown.

[0041] See Figure 1 , an embodiment of the present invention provides an electrical installation verification fixture, including a vehicle body frame 1 and a door fixture 2.

[0042] Among them, the main body of the vehicle body frame 1 adopts a frame structure, simulating the structure and layout of the actual vehicle, facilitating the arrangement and installation of electrical components on the vehicle body frame 1, and improving the versatility of the electrical installation verification fixture. The vehicle body frame 1 includes a bottom frame 11 and a top frame 12, and both the bottom frame 11 and the top frame 12 are rectangular. Combining with the layout method of the electric vehicle power battery, a first bracket 13 is provided at the bottom of the bottom frame 11, and the first brackets 13 are distributed at the four corners of the bottom frame 11. The vehicle body frame 1 is supported on the ground through the first brackets 13. The first brackets 13 have a certain height, and the first brackets 13 define a bottom space 14 for arranging the power battery 3 below the bottom frame 11. The power battery 3 can be arranged in the bottom space 14 simulating the actual vehicle, so as to realize the verification of the basic functions of the high-voltage related electrical components.

[0043] The top frame 12 is located above the bottom frame 11. The bottom frame 11 is connected to the top frame 12 through a second bracket 15. The second bracket 15 has a certain height, and the second bracket 15 defines a simulated driving cabin between the bottom frame 11 and the top frame 12. A large number of electrical components are integrated in the instrument panel components in the driving cabin. The vehicle body frame 1 is provided with an instrument panel fixture for clamping the instrument panel components at the front end of the driving cabin.

[0044] Combining with the layout method of the electric vehicle power battery 3, a first longitudinal beam 16 and a second longitudinal beam extending forward are provided at the front end of the bottom frame 11. The first longitudinal beam 16 and the second longitudinal beam are spaced a certain distance along the vehicle body transverse direction (i.e., the left-right direction in the figure). A cabin space 18 for arranging the power system is defined in front of the bottom frame 11 between the first longitudinal beam 16 and the second longitudinal beam, and electrical components such as the cabin wiring harness and headlights of the power system can be directly arranged on the first longitudinal beam 16 and the second longitudinal beam.

[0045] The door fixture 2 is independent of the vehicle body frame 1, and the corresponding number of door fixtures 2 can be specifically selected according to the actual vehicle model, such as two doors or four doors. The door fixture 2 is arranged on the side of the vehicle body frame 1 and is used for clamping the door components.

[0046] When it is necessary to verify the electrical installation system before actual vehicle assembly, each electrical component is arranged at the corresponding installation position of the electrical installation verification fixture according to the assembly position and connection method of the actual vehicle. After the installation is completed, the basic functions of the electronic equipment can be verified. The embodiment of the present invention conducts actual vehicle simulation through the vehicle body frame 1 and the door fixture 2, providing a more realistic verification arrangement carrier for electrical components such as the power battery 3, the instrument panel, the power system, and the doors. During the verification of the electrical installation system, each electrical component can be arranged on the electrical installation verification fixture according to the assembly position relationship of the actual vehicle, and finally the verification of the electrical installation system before actual vehicle assembly is completed. This technical solution can make the electrical installation verification better simulate the actual vehicle, can quickly arrange all low-voltage and high-voltage related electrical components of the whole vehicle, can cope with the verification of the basic functions of the electric vehicle electronic equipment, and has good versatility.

[0047] The first longitudinal beam 16 and the second longitudinal beam define an engine room space 18 for arranging the power system, and can also be used for arranging electrical components such as engine room wiring harnesses and vehicle lights. In some embodiments, referring to Figure 1 , there is a loading platform 19 for arranging engine room wiring harnesses and vehicle light components on the tops of the first longitudinal beam 16 and the second longitudinal beam, and the first longitudinal beam 16 and the second longitudinal beam provide support for the loading platform 19. By adding the loading platform 19, more sufficient arrangement space is provided for electrical components such as engine room wiring harnesses and vehicle lights inside the engine room at the front end of the vehicle body.

[0048] Furthermore, referring to Figure 1 , the front end of the cabin bottom frame 11 is hinged with a first plate member at a position corresponding to the first longitudinal beam 16. The first plate member can be lifted around the hinge position and lean against the vehicle body frame 1, and the first plate member can be lowered around the hinge position and overlap on the top of the first longitudinal beam 16. The front end of the cabin bottom frame 11 is hinged with a second plate member at a position corresponding to the second longitudinal beam. The second plate member can be lifted around the hinge position and lean against the vehicle body frame 1, and the second plate member can be lowered around the hinge position and overlap on the top of the second longitudinal beam. The first plate member overlapping on the top of the first longitudinal beam 16 and the second plate member overlapping on the top of the second longitudinal beam form the loading platform 19. In this embodiment, the first plate member and the second plate member can be spread out or retracted according to the actual usage needs of different vehicle models, improving the versatility of the entire electrical component verification fixture and meeting the usage requirements of multiple vehicle models.

[0049] In some embodiments, referring to Figure 1 , there is an opening at the front end of the engine room space 18, and the electrical component verification fixture further includes a first conveying device (not shown in the figure). The first conveying device is used to carry the power system in and out of the engine room space 18 through the opening. In this embodiment, through the interval between the first longitudinal beam 16 and the second longitudinal beam in the vehicle body transverse direction (i.e., the left - right direction in the figure), a non - enclosed opening form is formed at the front end of the engine room space 18. The power system can be sent into or withdrawn from the engine room space 18 before and after electrical component verification by the first conveying device with wheels, improving the convenience of electrical component verification.

[0050] In some embodiments, referring to Figure 1 , the electrical component verification fixture further includes a second conveying device 5. The second conveying device 5 is used to carry the power battery 3 in and out of the bottom space 14. The second conveying device 5 has casters, a loading platform, and a handrail. The loading platform is used to carry the power battery 3. The power battery 3 can be arranged and installed on the electrical component verification fixture with the second conveying device 5 during verification. Combined with the second conveying device 5 that can be manually controlled, it can directly enter and exit the bottom space 14 that is elevated under the vehicle body frame 1, improving the convenience of electrical component verification.

[0051] The instrument panel fixture is used to achieve the clamping and positioning of the instrument panel. Since the structural characteristics (different lateral lengths of the vehicle body) and installation postures (angles) of the instrument panel components of different vehicle models are not the same, in order to improve the versatility of the entire electrical installation verification fixture, in some embodiments, refer to Figure 1 , the instrument panel fixture includes a headstock 41 and a tailstock 42. The instrument panel component can be clamped between the headstock 41 and the tailstock 42, that is, the instrument panel fixture uses a two-end positioning method to achieve the clamping of the instrument panel in the passenger compartment. Among them, the distance between the headstock 41 and the tailstock 42 can be adaptively adjusted according to the specific length of the instrument panel component structure to meet the clamping requirements of instrument panel components of different vehicle models and different length dimensions. At the same time, the headstock 41 and the tailstock 42 can adjust the clamping rotation angle around their own axes to meet the correct assembly of instrument panel components of different vehicle models and different installation postures.

[0052] Specifically, refer to Figure 1 , the headstock 41 includes a headstock column 43, a headstock rotating shaft 44, a connecting flange 45 and a first crank 46. The headstock column 43 is connected to the vehicle body frame 1. The headstock rotating shaft 44 extends along the lateral direction of the vehicle body and is installed on the headstock column 43 through a first mounting seat 47. The headstock rotating shaft 44 is connected to the connecting flange 45 on the side of the first mounting seat 47 close to the tailstock 42. The connecting flange 45 is used to connect the instrument panel component to the headstock 41. The headstock rotating shaft 44 is connected to the first crank 46 on the side of the first mounting seat 47 far from the tailstock 42. The first crank 46 is used to drive the connecting flange 45 to adjust the clamping angle of the instrument panel component.

[0053] Refer to Figure 1 , the tailstock 42 includes a tailstock column 48, a tailstock rotating shaft 49 and a second crank 410. The tailstock column 48 is connected to the vehicle body frame 1. The tailstock rotating shaft 49 is coaxially arranged with the headstock rotating shaft 44 and is installed on the tailstock column 48 through a second mounting seat 411. The second crank 410 is connected to the tailstock rotating shaft 49 on the side of the second mounting seat 411 far from the headstock 41. When the instrument panel component is clamped, one end is connected to the connecting flange 45 of the headstock 41, and the other end is connected to the tailstock rotating shaft 49 of the tailstock 42. The headstock rotating shaft 44 and the tailstock rotating shaft 49 jointly define the rotation axis for adjusting the posture of the instrument panel component, and the correct assembly of the instrument panel component is achieved by means of the first crank 46 and the second crank 410.

[0054] For instrument panel components of different vehicle models and different length dimensions, the tailstock 42 adopts a telescopic column structure form. Refer to Figure 1, a bushing 412 is provided between the second mounting seat 411 and the tailstock rotating shaft 49. The tailstock rotating shaft 49 can rotate inside the bushing 412 to adjust the mounting angle of the instrument panel component. At the same time, the tailstock rotating shaft 49 can move axially along with the bushing 412 to adjust its position on the second mounting seat 411 to meet the clamping requirements of instrument panel components of different vehicle models and different lengths. An axial guide groove is provided on the outer side of the bushing 412, and a first locking component cooperating with the axial guide groove is provided on the second mounting seat 411. The first locking component is used to achieve positioning and locking after the telescopic column is adjusted in place.

[0055] In some embodiments, the door fixture 2 can adjust the clamping height of the door component for different vehicle models, improving the versatility of the embodiments of the present invention. Specifically, referring to Figure 1 , Figure 2 , Figure 3 , the door fixture 2 includes a support frame 21, a lifting frame 22, a lifting drive mechanism 23 and a door carrier 24. The support frame 21 is provided with a lifting guide structure that defines the lifting path of the lifting frame 22. The lifting frame 22 cooperates with the lifting guide structure. The lifting drive mechanism 23 is used to drive the lifting frame 22 to lift along the lifting guide structure. The door carrier 24 is connected to the lifting frame 22 and is used to carry the door component for electrical installation verification. In this embodiment, the door component for electrical installation verification is carried on the door carrier 24, and the lifting drive mechanism 23 drives the lifting frame 22 to drive the door carrier 24 to lift along the lifting guide structure until the door component is adjusted to the appropriate clamping height.

[0056] Furthermore, in some embodiments, referring to Figure 2 , Figure 3 , the support frame 21 includes a first column 25 and a second column 26. The first column 25 and the second column 26 extend in the height direction. The first column 25 and the second column 26 are spaced apart by a certain distance. An installation space for the lifting frame is defined between the first column 25 and the second column 26. The first column 25 and the second column 26 are provided with lifting guide grooves 27 on the side facing the installation space for the lifting frame, that is, the lifting guide structure. The lifting frame 22 is arranged in the installation space for the lifting frame. The lifting frame 22 is provided with lifting guide wheels cooperating with the lifting guide grooves 27 on both sides. The lifting drive mechanism 23 includes a pedal-operated jack arranged at the bottom of the lifting frame 22. The pedal-operated jack is hydraulically driven. Combining with the self-weight of the lifting frame 22 of the door carrier 24, the lifting is stable, and there is no need for an additional external power source, making it more convenient to use.

[0057] Of course, it can be understood that the driving of the lifting drive mechanism 23 can also adopt conventional power mechanisms such as electric push rods and cylinders to drive the lifting frame 22 to adjust the height of the door component.

[0058] In addition to the differences in clamping height, the clamping angles of the door components of different vehicle models also vary. In view of this, in some embodiments, the door fixture 2 has the ability to adjust the door angle. Refer to Figure 2 , Figure 3 . The lifting frame 22 is provided with a connecting frame 28 for connecting the door carrier 24. The connecting frame 28 is located on the side of the lifting frame 22. The connecting frame 28 is provided with a first rotating shaft seat 29, and the lifting frame 22 is provided with a second rotating shaft seat 210. The first rotating shaft seat 29 and the second rotating shaft seat 210 are connected by a first rotating shaft. The door carrier 24 can swing around the first rotating shaft along with the connecting frame 28. The lifting frame 22 is provided with a first adjusting screw 211 for adjusting the swinging angle of the connecting frame 28 around the first rotating shaft. In this embodiment, by arranging a connecting frame 28 that can swing relative to the lifting frame 22 between the lifting frame 22 and the door carrier 24, and cooperating with the first adjusting screw 211, the precise adjustment of the deflection angle of the door carrier 24 around the first rotating shaft can be realized.

[0059] Furthermore, in some embodiments, the door fixture 2 also has the ability to adjust the angle in the second direction. Refer to Figure 2 , Figure 3 . The door carrier 24 is provided with a second rotating shaft 212. The second rotating shaft 212 forms an angle with the first rotating shaft. For example, the first rotating shaft is arranged longitudinally along the vehicle body, and the second rotating shaft 212 is arranged transversely along the vehicle body. The connecting frame 28 is provided with a bearing seat 213 for connecting the second rotating shaft 212. The door carrier 24 can swing around the second rotating shaft 212. The second rotating shaft 212 is provided with a gear 214. The bearing seat 213 is provided with a rack 215 meshing with the gear 214 and a second adjusting screw 216 for driving the rack 215 to move. When the rack 215 moves, it meshes and drives with the gear 214, and then drives the second rotating shaft 212 to rotate through the gear 214. The second adjusting screw 216 cooperates with the gear 214 and the rack 215 to adjust the swinging angle of the door carrier 24 around the second rotating shaft 212. This embodiment adds the adjustment function of the deflection angle around the second rotating shaft 212, further increases the versatility of the electrical installation verification fixture, and expands the range of vehicle models that can perform electrical installation verification.

[0060] Furthermore, refer to Figure 2 , Figure 3, the door carrier 24 has a hanging box 217 that sinks relative to the second rotating shaft 212. The door component can be carried in the hanging box 217. The center of gravity of the hanging box 217 itself and after carrying the door component is below the second rotating shaft 212. By means of the first rotating shaft and the second rotating shaft 212 at the top of the hanging box 217, the yaw angle of the hanging box 217 is adjusted, improving the smoothness during the angle adjustment of the door carrier 24. Among them, the top of the hanging box 217 is open and there is an opening on one side, facilitating the door components of different vehicle models to be carried therein. A support tray 218 is provided at the bottom of the hanging box 217, and a limiting block 220 is provided at the top of the support tray 218 for providing limits for the door components placed therein. There is a gap between the bottom of the support tray 218 and the bottom of the hanging box 217, and an elastic component 219 is provided at the bottom of the support tray 218 to buffer the door components carried therein to avoid damage.

[0061] It can be understood that, as the direct bearing structure of the door component on the door fixture 2, the door carrier 24 can also adopt structural forms such as a frame and arranging fixtures, positioning pins, etc. on the frame.

[0062] In some embodiments, referring to Figure 2 , Figure 3 , the door fixture 2 further includes a plurality of adjustable support assemblies 221. The adjustable support assemblies 221 are connected to the bottom of the support frame 21 perpendicular to the height direction of the support frame 21. The adjustable support assemblies 221 extend in multiple directions at the bottom of the support frame 21, especially on the side and the back side where the door carrier 24 is located. Among them, the adjustable support assemblies 221 can adaptively adjust the length according to the weight of the carried door component to ensure the stability and versatility of the entire door fixture 2. Specifically, the adjustable support assembly 221 includes a first tubular member 222 and a second tubular member 223. The aperture of the first tubular member 222 is larger than that of the second tubular member 223. The second tubular member 223 is inserted into the first tubular member 222, and the first tubular member 222 and the second tubular member 223 can move relative to each other in a telescopic manner. The adjustable support assembly 221 is provided with a second locking member for locking the first tubular member 222 and the second tubular member 223. The second locking member can be a pin or a screw, etc., to lock the first tubular member 222 and the second tubular member 223 after telescoping to a specific length.

[0063] In addition, a caster 224 is provided at the end of the adjustable support assembly 221, and the entire door fixture 2 is supported by the casters, facilitating the movement and arrangement of the door fixture 2 around the vehicle body frame 1.

[0064] Furthermore, in some embodiments, the adjustable support assembly 221 can also adaptively adjust the angle according to the weight of the carried door component.
