DETAILED DESCRIPTION

[0056] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0057] As shown in Figure 1 and Figure 2 In an embodiment, the mounting device 100 includes a hinge module 10 and a guide rail 20. In use, the hinge module 10 is connected to the door, and the guide rail 20 is connected to the vehicle body. The guide rail 20 cooperates with the hinge module 10 to guide the forward and backward movement of the hinge module 10. In the directions shown in Figure 1 and Figure 2 The forward and backward directions are parallel to the X axis.

[0058] As shown in Figures 3 to 8As shown, in the left-right direction, the hinge module 10 comprises the first connecting assembly 1, the second connecting assembly 2 and the hinge wheel assembly 3 arranged in sequence, the second connecting assembly 2 is rotationally connected between the first connecting assembly 1 and the hinge wheel assembly 3 (i.e. one end of the second connecting assembly 2 is rotationally connected with the first connecting assembly 1, and the other end of the second connecting assembly 2 is rotationally connected with the hinge wheel assembly 3). The first connecting assembly 1 is suitable for connecting a vehicle door, and the hinge wheel assembly 3 is suitable for being movably connected to a guide rail 20 on a vehicle body in the front-back direction; the guide rail 20 is used for guiding the movement of the hinge wheel assembly 3 in the front-back direction; when the first connecting assembly 1 drives the second connecting assembly 2 and the hinge wheel assembly 3 to move in the front-back direction, the first connecting assembly 1 and the second connecting assembly 2 can be switched between the folded state and the unfolded state.

[0059] The first connecting assembly 1 and the second connecting assembly 2 are defined as a connecting unit, the first connecting assembly 1 and the second connecting assembly 2 in the folded state means that the connecting unit is in the folded state, at this time the hinge module 10 is also in the folded state, and the first connecting assembly 1 and the second connecting assembly 2 in the unfolded state means that the connecting unit is in the unfolded state, at this time the hinge module 10 is also in the unfolded state.

[0060] In the state shown in Figure 1 , Figure 3 and Figure 4 , the connecting unit is in the folded state; in the state shown in Figure 2 , Figure 5 and Figure 6 , the connecting unit is in the unfolded state.

[0061] In addition, the first connecting assembly 1, the second connecting assembly 2 and the hinge wheel assembly 3 can be arranged in sequence along the left-right direction, in the direction shown in Figures 1 to 6 , the left-right direction is parallel to the Y axis.

[0062] In the left-right direction, the distance between the first connecting assembly 1 and the hinge wheel assembly 3 when the connecting unit is in the folded state is less than the distance when the connecting unit is in the unfolded state; that is, when the connecting unit is in the folded state, the distance between the first connecting assembly 1 and the hinge wheel assembly 3 in the left-right direction is L1, and when the connecting unit is in the unfolded state, the distance between the first connecting assembly 1 and the hinge wheel assembly 3 in the left-right direction is L2, wherein L1 < L2.

[0063] In addition, as shown in Figure 3 and Figure 4As shown, the second connecting assembly 2 is provided with a first limiting structure 4; when the connecting unit is in the folded state, the first limiting structure 4 is separated from the vehicle body; when the connecting unit is in the unfolded state, the first limiting structure 4 is combined with the vehicle body, and the connecting unit can move forward and backward in the unfolded state, that is, at this time, when the first connecting assembly 1 moves forward and backward, the second connecting assembly 2 also moves forward and backward, and the connecting unit remains in the unfolded state.

[0064] Specifically, when the connecting unit is in the folded state, the first limiting structure 4 is separated from the second limiting structure 5 on the vehicle body, thereby realizing the separation of the first limiting structure 4 from the vehicle body; when the connecting unit is in the unfolded state, the first limiting structure 4 cooperates with the second limiting structure 5, thereby realizing the combination of the first limiting structure 4 with the vehicle body.

[0065] When the hinge module 10 is applied to a vehicle, the first connecting assembly 1 can move forward and backward with the vehicle door to realize the opening and closing of the vehicle door. Among them, during the process of switching the connecting unit from the folded state to the unfolded state, or during the process of switching the connecting unit from the unfolded state to the folded state, the vehicle door and the hinge module 10 can be regarded as being in a rotating stage; during the process of moving the connecting unit forward and backward in the unfolded state, the vehicle door and the hinge module 10 can be regarded as being in a translation stage. In addition, when the first limiting structure 4 cooperates with the second limiting structure 5, they have a small gap in the left-right direction, and when the vehicle door is subjected to an external force in the direction of the vehicle interior, the first limiting structure 4 and the second limiting structure 5 will resist, so that the connecting unit remains in the unfolded state, thereby avoiding the folding of the connecting unit in the translation stage.

[0066] When the vehicle door is closed, the connecting unit is in the folded state; when it is necessary to open the vehicle door, force can be applied to the vehicle door in the forward and backward directions, thereby driving the first connecting assembly 1, the second connecting assembly 2 and the hinge wheel assembly 3 to move in the forward and backward directions, at this time, force can be applied to the second connecting assembly 2 to make the second connecting assembly 2 rotate, and finally make the connecting unit move from the folded state to the unfolded state, at this time the first limiting structure 4 cooperates with the second limiting structure 5, then the connecting unit can continue to move with the vehicle door and the hinge wheel assembly 3 in the unfolded state until the vehicle door is completely opened. When it is necessary to close the vehicle door, the force is applied to the vehicle door in the opposite direction, and the connecting unit can move with the vehicle door and the hinge wheel assembly 3 in the unfolded state, until the first limiting structure 4 and the second limiting structure 5 are separated, at this time, the force applied to the second connecting assembly 2 will make the second connecting assembly 2 rotate until the vehicle door is completely closed, and in this process, the connecting unit will gradually switch from the unfolded state to the folded state.

[0067] In one scenario, when the vehicle door moves forward, the vehicle door can be closed; when the vehicle door moves backward, the vehicle door can be opened. Figures 1 to 6 In the direction shown, the direction indicated by the X-axis arrow is the direction from front to back.

[0068] In the embodiment, the connecting unit in the folded state can reduce the size of the entire hinge module 10 in the left-right direction, so that the space of the entire installation device 100 in the left-right direction of the vehicle can be reduced, which is beneficial to the arrangement of the battery pack and the increase of the size of the battery pack, thereby improving the capacity of the battery.

[0069] In addition, the opening process of the vehicle door includes two movements, specifically, the first movement is performed first, and then the second movement is performed. In the first movement, the vehicle door has not only a rearward movement but also an outward movement (i.e., moving away from the vehicle body in the left-right direction), at this time, the vehicle door is in a rotating stage; in the second movement, the vehicle door only needs to move backward, at this time, the vehicle door is in a translating stage. Therefore, in the prior art, the track of the guide rail usually includes two structures, one of which is a curved guide rail, and the other is a straight guide rail, so that the existing track has an overall L-shaped structure. In addition, in the prior art, the curved guide rail is used to cooperate with the hinge module to achieve the first movement, and the straight guide rail is used to cooperate with the hinge module to achieve the second movement. The curved guide rail is curved in the left-right direction, which will invade the battery pack installation space, thus reducing the space for installing the battery pack on the vehicle body.

[0070] In the embodiment, the connecting unit can realize the rearward movement and the outward movement of the vehicle door in the unfolding action (i.e., the process of rotating from the folded state to the unfolded state), i.e., the first movement can be achieved in this process. When the connecting unit moves backward with the vehicle door in the unfolded state, the second movement is achieved. Therefore, when the hinge module 10 of the embodiment is used, the curved guide rail in the prior art can be replaced by a straight guide rail (equivalent to not setting a curved guide rail), or the curvature of the curved guide rail in the prior art can be reduced (i.e., the maximum size of the curved guide rail in the left-right direction is reduced), so that the invasion of the track 9 of the embodiment to the battery pack installation space can be reduced, and the vehicle body can have a larger battery pack installation space.

[0071] In addition, the hinge module 10 includes the first connecting assembly 1, the second connecting assembly 2, and the hinge wheel assembly 3 connected in sequence, which means that the hinge module 10 includes the first connecting assembly 1, the second connecting assembly 2, and the hinge wheel assembly 3, wherein the first connecting assembly 1 and the second connecting assembly 2 are rotationally connected, and the second connecting assembly 2 is rotationally connected with the hinge wheel assembly 3. In addition, the axis of rotation of the second connecting assembly 2 relative to the first connecting assembly 1 (defined as the first axis) and the axis of rotation of the second connecting assembly 2 relative to the hinge wheel assembly 3 (defined as the second axis) are spaced apart, and the first axis and the second axis are not perpendicular, and both the first axis and the second axis intersect the front-rear direction and the left-right direction.

[0072] Preferably, the first axis and the second axis are arranged in parallel and parallel to the vertical direction. Figures 1 to 6 In the shown direction, the vertical direction is parallel to the Z-axis.

[0073] As shown in the drawings, in an embodiment, the first guiding structure 6 is arranged on the second connecting assembly 2, and the second guiding structure 7 is arranged on the vehicle body. When the first connecting assembly 1 drives the second connecting assembly 2 and the hinged wheel assembly 3 to move forward and backward, the second guiding structure 7 on the vehicle body can apply force to the first guiding structure 6 on the second connecting assembly 2, so as to switch the connecting unit between the folded state and the unfolded state. Figure 4

[0074] Specifically, when the first connecting assembly 1 moves backward, the first guiding structure 6 can receive the force applied by the second guiding structure 7 on the vehicle body, so as to drive the second connecting assembly 2 to rotate, and then switch the connecting unit from the folded state to the unfolded state. In this process, the first limiting structure 4 also moves together with the second connecting assembly 2, and when the connecting unit moves to the unfolded state, the first limiting structure 4 is combined to the vehicle body (that is, the first limiting structure 4 moves to cooperate with the second limiting structure 5), so that the connecting unit can move backward with the hinged wheel assembly 3 in the unfolded state. When the first connecting assembly 1 moves forward, the first guiding structure 6 can receive the force applied by the second guiding structure 7, which can reversely drive the second connecting assembly 2, so as to switch the connecting unit from the unfolded state to the folded state, and make the first limiting structure 4 disengage from the vehicle body.

[0075] In an embodiment, when the connecting unit is in the unfolded state, the first guiding structure 6 disengages from the second guiding structure 7. In this way, it can not only avoid the interference of the second guiding structure 7 to the subsequent movement of the second connecting assembly 2, but also reduce the size of the first guiding structure 6 and / or the second guiding structure 7, so as to reduce the weight and material cost.

[0076] As shown in the drawings, in an embodiment, the first guiding structure 6 includes a guiding groove 61, and the second guiding structure 7 includes a guiding block 71; when the connecting unit is in the folded state, the guiding block 71 is located in the guiding groove 61; the guiding block 71 can apply force to the groove wall of the guiding groove 61, so as to drive the second connecting assembly 2 to rotate; when the connecting unit is in the unfolded state, the guiding block 71 is located outside the guiding groove 61. Figure 4

[0077] ​​That is, when the door is pulled backward, the second connecting assembly 2 is also moved backward, at this time, the groove wall of the guide groove 61 can press the guide block 71, so that the guide block 71 can apply force to the groove wall of the guide groove 61, thereby rotating the second connecting assembly 2 until the connecting unit is in the unfolded state, at this time, the guide block 71 moves out of the guide groove 61, and the guide block 71 will not apply force to the second connecting assembly 2 when the second connecting assembly 2 is subsequently moved backward with the door. When the door is pulled forward, the guide block 71 will enter the guide groove 61 after the second connecting assembly 2 is moved forward with the door for a distance, and then the guide block 71 will apply force to the groove wall of the guide groove 61 when the second connecting assembly 2 continues to move forward with the door, thereby rotating the second connecting assembly 2 until the connecting unit is in the folded state, at this time, the door is moved forward to the position and stops moving forward.

[0078] In the prior art, in order to realize the folding and unfolding of the hinge module, some schemes replace the L-shaped track with two guide rails (and the corresponding slider mechanisms cooperating with the two guide rails), one of which is a straight guide rail and the other of which is a curved guide rail; and one section of the curved guide rail is in a curved structure and the other section is in a straight line structure. In the embodiment, the folding and unfolding of the hinge module 10 can be realized through the cooperation of the first guide structure 6 and the second guide structure 7. Compared with the scheme, the arrangement of the embodiment can omit one guide rail (and the slider mechanism cooperating with the guide rail), which not only can reduce the cost, but also can further reduce the occupation of the hinge module 10 to the installation space of the battery pack.

[0079] As shown in FIG. 1, Figure 4 In an embodiment, the guide groove 61 is arranged on the lower surface of the second connecting assembly 2, and in the left-right direction, the guide groove 61 has two side walls, which are a first side wall 62 and a second side wall 63, respectively, and in the left-right direction, the first side wall 62 is located between the second side wall 63 and the guide rail 20. In other embodiments, the guide groove 61 can also be arranged on the upper surface of the second connecting assembly 2, and at this time, other arrangements of the guide groove 61 can be the same as those in the above embodiment.

[0080] When the door is moved backward, the guide block 71 can apply force to the first side wall 62, so that the end of the second connecting assembly 2 connected to the first connecting assembly 1 is away from the guide rail 20, and the end of the second connecting assembly 2 provided with the first limiting structure 4 is close to the guide rail 20. When the door is moved forward, the guide block 71 can apply force to the second side wall 63, so that the end of the second connecting assembly 2 connected to the first connecting assembly 1 is close to the guide rail 20, and the end of the second connecting assembly 2 provided with the first limiting structure 4 is away from the guide rail 20.

[0081] When the connecting unit is in the folded state and moves from front to back, the guide block 71 can apply force to the first sidewall 62 of the guide groove 61, causing the second connecting component 2 to rotate, so that the connecting unit can switch to the unfolded state; when the connecting unit is in the unfolded state and moves from back to front, the guide block 71 can apply force to the second sidewall 63 of the guide groove 61, causing the second connecting component 2 to rotate in the opposite direction, so that the connecting unit can switch to the folded state; when the connecting unit is in the folded state, in the left-right direction, the guide block 71 is located between the first sidewall 62 and the second sidewall 63, and the first sidewall 62 is located between the guide block 71 and the guide rail 20.

[0082] When the connecting unit is in the folded state, at least a portion of the guide groove 61 gradually moves away from the guide rail 20 in the left-right direction along the front-to-back direction. Thus, when the second connecting assembly 2 moves from front to back, the inner sidewall of the guide groove 61 (i.e., the first sidewall 62) presses against the guide block 71, thereby exerting force on the first sidewall 62. When the connecting unit is in the unfolded state, at least a portion of the guide groove 61 gradually moves closer to the guide rail 20 in the left-right direction along the front-to-back direction. Thus, when the second connecting assembly 2 moves from back to front, the outer sidewall of the guide groove 61 (i.e., the second sidewall 63) presses against the guide block 71, thereby exerting force on the second sidewall 63.

[0083] In one embodiment, the guide groove 61 is a curved groove, such as an arc-shaped groove. The concave portion of the guide groove 61 faces the guide rail 20, and the convex portion of the guide groove 61 faces the door. In this case, the first sidewall 62 and the second sidewall 63 are also curved.

[0084] like Figure 4 As shown, in one embodiment, the first guide structure 6 further includes a receiving groove 64, which is disposed on the same surface as the guide groove 61 on the second connecting assembly 2, and the receiving groove 64 communicates with the guide groove 61. When the connecting unit changes from a folded state to an unfolded state, the guide block 71 moves out of the guide groove 61 and enters the receiving groove 64. Subsequently, when the connecting unit continues to move backward in the unfolded state, the guide block 71 remains in the receiving groove 64. At this time, the groove wall of the receiving groove 64 can shield and protect the guide block 71, preventing it from being hit by foreign objects, so as to ensure its cooperation with the first side wall 62 and the second side wall 63. In addition, the receiving groove 64 may extend backward through the second connecting assembly 2, or it may not extend backward through the second connecting assembly 2.

[0085] Of course, in other embodiments, the guide groove 61 may extend rearward through the second connecting component 2, and when the guide block 71 moves out of the guide groove 61, the guide block 71 moves to the outside of the second connecting component 2. In this case, the receiving groove 64 is not provided on the second connecting component 2.

Of course, the first rotating shaft 13 can also be capable of rotating relative to the third mounting plate 121 and the fifth mounting plate 123, in which case, the third mounting plate 121 and the fifth mounting plate 123 are each provided with a corresponding through hole, the two ends of the first rotating shaft 13 pass through the third mounting plate 121 and the fifth mounting plate 123 respectively, and the two ends of the first rotating shaft 13 are connected with a first stop block and a second stop block respectively, wherein the first stop block, the third mounting plate 121, the fifth mounting plate 123 and the second stop block are sequentially arranged in the vertical direction, the first stop block is capable of abutting against the third mounting plate 121, and the second stop block is capable of abutting against the fifth mounting plate 123, so that the first rotating shaft 13 can be prevented from falling off the third mounting plate 121 and the fifth mounting plate 123 through the first stop block and the second stop block.

[0098] The fourth connecting plate 214 is connected below the second connecting plate 212, and the fifth connecting plate 215 is connected below the third connecting plate 213.

Specifically, the first connecting plate 211 has a first connecting hole, and the fourth connecting plate 214 has a second connecting hole. The first connecting hole and the second connecting hole are coaxially arranged. The first rotating shaft 13 on the first connecting assembly 1 passes through the first connecting hole and the second connecting hole, thereby realizing the rotatable connection between the fourth connecting plate 214 and the first connecting plate 211 to the first connecting assembly 1. In addition, in the vertical direction, the first connecting hole penetrates the first connecting plate 211, and the second connecting hole penetrates the second connecting plate 212.

[0100] Furthermore, after assembly, the first connector 21 is located between the third mounting plate 121 and the fifth mounting plate 123.

The third and fourth connecting holes are coaxially arranged, and the second rotating shaft 34 on the hinge wheel assembly 3 passes through the third and fourth connecting holes, thereby realizing the rotatable connection between the fifth connecting plate 215 and the first connecting plate 211 to the hinge wheel assembly 3. In addition, in the vertical direction, the third connecting hole penetrates through the first connecting plate 211, and the fourth connecting hole penetrates through the fifth connecting plate 215.

[0102] like Figure 9 As shown, in one embodiment, the second connecting member 22 includes a sixth connecting plate 221, a seventh connecting plate 222, and an eighth connecting plate 223. The sixth connecting plate 221 is connected to the first connecting plate 211. The seventh connecting plate 222 and the eighth connecting plate 223 are both connected to the sixth connecting plate 221, and the seventh connecting plate 222 and the eighth connecting plate 223 are spaced apart in the left-right direction. The sixth connecting plate 221, the seventh connecting plate 222, and the eighth connecting plate 223 together form a receiving space formed by the guide groove 61 and the receiving groove 64. At this time, the second connecting member 22 passes through both the front and rear ends of the receiving space.

[0103] After assembly, the seventh connecting plate 222 is located on the side of the eighth connecting plate 223 away from the first connecting assembly 1, a part of the seventh connecting plate 222 is used to form the first side wall 62 of the guide groove 61, and a part of the eighth connecting plate 223 is used to form the second side wall 63 of the guide groove 61. A part of the seventh connecting plate 222 is used to form the side wall of the accommodating groove 64, and a part of the eighth connecting plate 223 is used to form the side wall of the accommodating groove 64.

[0104] As shown in Figure 10 , the second connecting piece 22 further comprises a ninth connecting plate 224, the ninth connecting plate 224 is connected with the sixth connecting plate 221, the seventh connecting plate 222 and the eighth connecting plate 223 respectively, and the ninth connecting plate 224 seals one end opening of the accommodating space. Specifically, the ninth connecting plate 224 seals one end opening of the guide groove 61 away from the accommodating groove 64, and the accommodating groove 64 extends backward through the second connecting piece 22.

[0105] As shown in Figure 10 , in an embodiment, the second connecting assembly 2 further comprises a third connecting piece 23, the third connecting piece 23 is used to connect the second connecting piece 22 and the first limiting structure 4.

[0106] As shown in Figure 10 and Figure 11 , the third connecting piece 23 is connected to the ninth connecting plate 224, the third connecting piece 23 is L-shaped structure, which comprises a tenth connecting plate 231 and an eleventh connecting plate 232, the tenth connecting plate 231 is connected to the ninth connecting plate 224, the eleventh connecting plate 232 is connected to the tenth connecting plate 231 and located on the side of the tenth connecting plate 231 away from the second connecting piece 22, and the first limiting structure 4 is connected to the eleventh connecting plate 232.

[0107] As shown in Figure 2 , Figure 3 , Figure 10 and Figure 11 , in the front and rear direction, the first limiting structure 4 comprises a limiting block 41, and the second limiting structure 5 comprises a limiting groove 51 (i.e. the vehicle body is provided with a limiting groove 51); when the connecting unit is in the folded state, the limiting block 41 is located outside the limiting groove 51 to realize disengagement with the vehicle body; when the connecting unit is in the unfolded state, the limiting block 41 is located inside the limiting groove 51 to realize combination with the vehicle body, wherein the limiting groove 51 is suitable for limiting the position of the first limiting structure 4 in the left and right direction. Such arrangement can avoid the adverse effect of the first limiting structure 4 on the unfolding action of the second connecting assembly 2.

[0108] In one embodiment, the limiting block 41 is a cylindrical structure and can rotate relative to the second connecting component 2. The axis around which the limiting block 41 rotates relative to the second connecting component 2 (defined as the third axis) can be parallel to the first axis. In this case, the third axis can also be parallel to the vertical direction, and the third axis can be the axis of the limiting block 41. In this case, the limiting block 41 is a roller structure.

[0109] When the door moves back and forth, it can also drive the limiting block 41 to move back and forth. When the limiting block 41 is located in the limiting groove 51, the limiting block 41 can slide along the limiting groove 51, wherein the limiting groove 51 extends in the front and back direction.

[0110] In addition, during actual operation, the side of the limiting block 41 can either contact the side wall of the limiting groove 51 within the limiting groove 51 or have a small gap with the side wall of the limiting groove 51, so as to restrict the position of the limiting block 41 in the left-right direction by the side wall of the limiting groove 51, thereby restricting the position of the first limiting structure 4 in the left-right direction. Specifically, the above-mentioned arrangement to prevent the connecting unit from folding during the translational phase refers to the side of the limiting block 41 contacting the side wall of the limiting groove 51 within the limiting groove 51 or having a small gap with the side wall of the limiting groove 51.

[0111] Furthermore, when the limiting block 41 moves back and forth with the second connecting component 2, the friction between the limiting block 41 and the side wall of the limiting groove 51 can be reduced because the limiting block 41 can rotate.

[0112] like Figure 10 As shown, in one embodiment, the first limiting structure 4 further includes a connecting shaft 42 and a stop block 43. The eleventh connecting plate 232 is provided with a fifth connecting hole, which penetrates the eleventh connecting plate 232 in a vertical direction. The connecting shaft 42 passes through the fifth connecting hole, and the two ends of the connecting shaft 42 are respectively connected to the stop block 43 and the limiting block 41. When the connecting shaft 42 moves along the direction from the stop block 43 to the limiting block 41, the stop block 43 can abut against the eleventh connecting plate 232. When the connecting shaft 42 moves along the direction from the limiting block 41 to the stop block 43, the limiting block 41 can abut against the eleventh connecting plate 232. This can prevent the first limiting structure 4 from falling off the eleventh connecting plate 232.

[0113] In addition, the connecting shaft 42 and the limiting block 41 can be coaxial.

[0114] After assembly, the limiting block 41 can be located below the eleventh connecting plate 232, and the blocking block 43 can be located above the eleventh connecting plate 232.

[0115] like Figure 12 and Figure 13As shown, in one embodiment, the hinge wheel assembly 3 includes a support member 31, a load-bearing member 32, and a guide member 33. The support member 31 is rotatably connected to the second connecting component 2, thereby achieving a rotatable connection between the hinge wheel assembly 3 and the second connecting component 2. The load-bearing member 32 and the guide member 33 are both connected to the support member 31. After assembly, the side of the load-bearing member 32 abuts against the guide rail 20 so that the load-bearing member 32 is supported by the guide rail 20, thereby achieving support for the hinge wheel assembly 3. The guide member 33 cooperates with the guide rail 20 so that the back-and-forth movement of the guide member 33 is guided by the guide rail 20, thereby achieving guidance for the back-and-forth movement of the hinge wheel assembly 3.

[0116] In one embodiment, the load-bearing member 32 is a load-bearing wheel, and the guide member 33 is a guide wheel. Both the load-bearing wheel and the guide wheel can rotate relative to the support member 31 around their own axis.

[0117] In addition, when the hinge wheel assembly 3 moves back and forth, the load-bearing wheel can rotate relative to the support member 31 and the guide rail assembly, and the guide wheel can rotate relative to the support member 31 and the guide rail assembly. At this time, there is rolling friction between the load-bearing wheel and the guide rail assembly, and there is rolling friction between the guide wheel and the guide rail assembly.

[0118] In one embodiment, the axis of the load-bearing wheel may be parallel to the left-right direction, and the axis of the guide wheel may be parallel to the vertical direction.

[0119] In one embodiment, the guide wheels and the load-bearing wheels are arranged at intervals in the front-to-back direction. Additionally, there are two guide wheels, one on the front and one on the back of the load-bearing wheel.

[0120] like Figure 13 As shown, in one embodiment, the hinge wheel assembly 3 further includes a second rotating shaft 34, which connects the support member 31 and the second connecting assembly 2 to achieve a rotational connection between the support member 31 and the second connecting assembly 2.

[0121] like Figure 13 As shown, in one embodiment, the support member 31 includes a first support plate 311, a second support plate 312, a third support plate 313, and a fourth support plate 314;

[0122] The first support plate 311 and the second support plate 312 are both connected to the third support plate 313 and located on the side of the third support plate 313 close to the first connecting assembly 1, and the first support plate 311 and the second support plate 312 are arranged in the vertical direction; the fourth support plate 314 is connected to the third support plate 313 and located on the side of the third support plate 313 away from the first connecting assembly 1; the first support plate 311 is provided with a first through hole, the second support plate 312 is provided with a second through hole, and the second rotating shaft 34 is arranged in the first through hole and the second through hole; the load wheel is mounted on the third support plate 313 and located on the side of the third support plate 313 away from the first connecting assembly 1; the guide wheel is mounted on the fourth support plate 314.

[0123] In addition, the number of the fourth support plates 314 is two, and the two fourth support plates 314 are arranged on the front and back sides of the load wheel respectively, and one guide wheel is connected to one fourth support plate 314.

[0124] After assembly, the first connecting plate 211, the first support plate 311, the second support plate 312 and the fifth connecting plate 215 are arranged in the vertical direction in sequence.

[0125] As shown in Figure 9 and Figure 10 In an embodiment, the hinge module 10 further comprises a first clamping member 14 and a second clamping member 24, the first clamping member 14 is connected to the first connecting assembly 1, and the second clamping member 24 is connected to the second connecting assembly 2; when the connecting unit is switched from the folded state to the unfolded state, the first clamping member 14 and the second clamping member 24 can cooperate to prevent the second connecting assembly 2 from rotating relative to the first connecting assembly 1, thereby facilitating the connecting unit to remain in the unfolded state; when the connecting unit is in the unfolded state and is switched from the unfolded state to the folded state, the first clamping member 14 and the second clamping member 24 can be disengaged, so that the second connecting assembly 2 can move relative to the first connecting assembly 1, and the connecting unit can move to the folded state.

[0126] In an embodiment, when the first clamping member 14 cooperates with the second clamping member 24, the two can be clamped together.

[0127] As shown in Figure 9As shown in the drawings, in an embodiment, the first clamping member 14 comprises a first elastic sheet 141 and a second elastic sheet 142, both of which are connected to the first connecting assembly 1, and the second clamping member 24 comprises a limiting column 241 connected to the second connecting assembly 2. When the first clamping member 14 and the second clamping member 24 are matched, the limiting column 241 is located between the first elastic sheet 141 and the second elastic sheet 142, at which time the first elastic sheet 141 and the second elastic sheet 142 can clamp the limiting column 241; when the first clamping member 14 and the second clamping member 24 are disengaged, the limiting column 241 is located outside the space between the first elastic sheet 141 and the second elastic sheet 142.

[0128] As shown in the drawings, Figure 9 in an embodiment, the first elastic sheet 141 and the second elastic sheet 142 are both connected to the fourth mounting plate 122 and located between the third mounting plate 121 and the fifth mounting plate 123, in addition, the first elastic sheet 141 and the second elastic sheet 142 are arranged along the arrangement direction of the first mounting member 11 and the second mounting member 12.

[0129] In addition, the number of the first elastic sheet 141 and the second elastic sheet 142 can be multiple, and the number of the first elastic sheet 141 and the second elastic sheet 142 can be the same, and one-to-one correspondence; each first elastic sheet 141 is arranged along the vertical direction, and each second elastic sheet 142 is arranged along the vertical direction. When the first clamping member 14 and the second clamping member 24 are matched, each first elastic sheet 141 and the corresponding second elastic sheet 142 clamp the limiting column 241.

[0130] As shown in the drawings, Figure 10 the two ends of the limiting column 241 are respectively connected to the first connecting plate 211 and the fourth connecting plate 214, and the two ends of the limiting column 241 can be respectively fixedly connected to the first connecting plate 211 and the fourth connecting plate 214. In addition, the limiting column 241 is arranged apart from the second connecting plate 212. In addition, the limiting column 241 can be a cylindrical structure.

[0131] As shown in the drawings, Figure 8 and Figure 10 in an embodiment, the hinge module 10 further comprises an elastic assembly 8 connected to the hinge wheel assembly 3 and the second connecting assembly 2 respectively; when the hinge wheel assembly 3 rotates relative to the second connecting assembly 2, the elastic assembly 8 can be forced to produce elastic deformation.

[0132] In one scenario, when the second connecting assembly 2 rotates to switch the connecting unit from the unfolded state to the folded state, the elastic assembly 8 can be forced to produce elastic deformation. When the connecting unit is in the folded state, the elastic assembly 8 is in the state of elastic deformation, and the elastic force of the elastic assembly 8 has a tendency to unfold the second connecting assembly 2. In this way, the elastic assembly 8 can provide driving force for the second connecting assembly 2, facilitating the unfolding of the connecting unit.

[0133] Of course, in other embodiments, when the second connecting assembly 2 rotates to switch the connecting unit from the folded state to the unfolded state, the elastic assembly 8 can be forced to produce elastic deformation. In this scenario, when the connecting unit is in the unfolded state, the elastic assembly 8 is in the state of elastic deformation, and the elastic force of the elastic assembly 8 has a tendency to fold the second connecting assembly 2. In this way, the elastic assembly 8 can provide driving force for the second connecting assembly 2, facilitating the folding of the connecting unit.

[0134] In one embodiment, the elastic assembly 8 includes a torsion spring 81, and the torsion spring 81 is connected to the hinge wheel assembly 3 and the second connecting assembly 2, respectively. When the hinge wheel assembly 3 rotates relative to the second connecting assembly 2, the torsion spring 81 can be forced to produce elastic deformation. That is, the elastic deformation of the elastic assembly 8 is actually the elastic deformation of the torsion spring 81.

[0135] The torsion spring 81 can be a spiral spring, which can be sleeved on the second rotating shaft 34. In addition, one end of the torsion spring 81 can be connected to the third support plate 313, and the other end of the torsion spring 81 can be connected to the third connecting plate 213. Specifically, the third support plate 313 is provided with a first mounting hole, and the third connecting plate 213 is provided with a second mounting hole; one end of the torsion spring 81 is inserted into the first mounting hole to achieve connection with the third support plate 313; the other end of the torsion spring 81 is inserted into the second mounting hole to achieve connection with the third connecting plate 213.

[0136] As shown in Figure 14 and Figure 15 In one embodiment, the guide rail 20 includes a rail 9, and the rail 9 is adapted to be mounted on the vehicle body. The rail 9 cooperates with the hinge wheel assembly 3 to guide the movement of the hinge wheel assembly 3 in the front-rear direction. That is, the guide rail 20 actually guides the movement of the hinge wheel assembly 3 in the front-rear direction through the rail 9.

[0137] In one embodiment, the rail 9 is a straight rail and extends along the front-rear direction, that is, the length direction of the rail 9 is parallel to the front-rear direction. In this way, the vehicle body can have a larger battery pack mounting space.

In this way, the support effect and the guiding effect of the track 9 on the hinge wheel assembly 3 can be improved.

[0139] In the present embodiment, one groove wall surface refers to the surface of the track 9 used to enclose the groove.

[0140] In addition, when the load-bearing piece 32 is a load-bearing wheel, the side surface of the load-bearing wheel abuts against the wall surface of the first groove 91; when the guide piece 33 is a guide wheel, the side surface of the guide wheel abuts against the wall surface of the second groove 92.

[0141] In addition, both the first groove 91 and the second groove 92 can be straight-line extending grooves, and both of them can be rectangular grooves. Moreover, the first groove 91 can be completely through the track 9 in the front-rear direction, and the second groove 92 can be completely through the track 9 in the front-rear direction.

[0142] As shown in the figure, Figure 16 In an embodiment, the first groove 91 is arranged on the surface of the track 9 close to the first connecting assembly 1, and the lower side surface of the first groove 91 (defined as a load-bearing surface 93) is used to support the load-bearing piece 32; the second groove 92 is arranged on the upper side surface of the first groove 91.

[0143] In the present embodiment, the surface of the track 9 close to the first connecting assembly 1 refers to the surface of the track 9 close to the door in the left-right direction.
