Detailed implementation mode

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] See Figure 1 、 Figure 2 and Figure 3, embodiments of the present application provide a test platform for a new energy vehicle shift mechanism. The shift mechanism 3 includes a shift lever 31. The test platform includes a driving component 1, and the driving component 1 includes a seat body 11, a plurality of sprockets 12, a chain 13, a plurality of moving parts 15, a plurality of supporting parts 17, a locking component, and a force transmission part 19. The plurality of sprockets 12 are rotatably arranged on the seat body 11 at intervals in a first direction. The chain 13 is wound around the outer circumferences of the plurality of sprockets 12, and the sprockets 12 and the chain 13 are engaged. The chain 13 includes a plurality of chain links 114 that are sequentially rotatably connected. The plurality of moving parts 15 are arranged corresponding to the chain links 114, and the moving parts 15 are connected to the chain links 114 in a position-adjustable manner in a second direction. The first direction is perpendicular to the second direction. The plurality of supporting parts 17 are arranged corresponding to the moving parts 15, and the supporting parts 17 are rotatably connected to the moving parts 15. The rotation axis of the supporting parts 17 is perpendicular to the second direction. The locking component is used to lock the supporting parts 17. Along the second direction, the force transmission part 19 is movably connected to the seat body 11. One side of the force transmission part 19 is connected to the shift lever 31, and a guide wheel 113 is rotatably arranged on the other side. An elastic member 110 is arranged between the force transmission part 19 and the seat body 11, and the elastic member 110 is used to provide an elastic force that enables the guide wheel 113 to abut against the supporting part 17.

[0030] The first direction can be Figure 1 the direction shown by the X-axis in Figure 1 and the second direction can be

[0031] The driving structure of the sprocket 12 can be selected from existing structures and will not be elaborated here.

[0032] The chain 13 is wound around the outer circumferences of the plurality of sprockets 12 and the sprockets 12 and the chain 13 are engaged, so that when the sprockets 12 rotate, the chain 13 can move.

[0033] The moving part 15 is connected to the chain link 114 in a position-adjustable manner in the second direction, so that the position of the moving part 15 relative to the chain link 114 in the second direction can be adjusted, and further the position of the supporting part 17 relative to the chain link 114 in the second direction can be adjusted.

[0034] Under the action of the locking component, the supporting part 17 can have two states. One is the locked state, in which the supporting part 17 cannot rotate relative to the moving part 15. The other is the unlocked state, in which the supporting part 17 can rotate relative to the moving part 15.

[0035] The moving part 15 being arranged corresponding to the chain link 114 means that the number of the moving parts 15 and the chain links 114 is the same, and they correspond to each other one by one.

[0036] The supporting part 17 is arranged corresponding to the moving part 15, and the number of the supporting parts 17 and the moving parts 15 is the same, and they correspond to each other one by one.

[0037] In the embodiment of the present application, the sprockets 12 can be arranged in two groups, with two sprockets 12 in each group. The two groups of sprockets 12 are arranged along the second direction, and the sprockets 12 in each group are arranged along the first direction. Correspondingly, the chains 13 can be arranged in two, and the two chains 13 are arranged along the second direction. This can improve the stability of the movement of the chains 13. At this time, the one-to-one correspondence between the moving parts 15 and the chain links 114 means that the moving parts 15 and the chain links 114 of one of the chains 13 are in one-to-one correspondence.

[0038] The opposite chain links 114 of the two chains 13 can be connected by a connecting part 16, and the moving part 15 can be movably connected to the connecting part 16.

[0039] Furthermore, by providing guide holes in the chain links 114 or the moving parts 15 and passing the moving parts 15 through the guide holes, the moving parts 15 can move relative to the chain links 114.

[0040] The force transmission part 19 is connected to the shift lever 31, so that the force transmission part 19 can move the shift lever 31.

[0041] Which side of the support part 17 the guide wheel 113 specifically abuts against can be set as needed. For example, the shift mechanism 3 and the support part 17 can be respectively arranged on both sides of the force transmission part 19. At this time, the guide wheel 113 can abut against the side of the support part 17 facing away from the shift mechanism 3. At this time, the elastic part 110 applies an elastic force to the guide wheel 113 to keep it abutting against the side of the support part 17 facing away from the shift mechanism 3.

[0042] The elastic part 110 can be a spring.

[0043] Multiple support parts 17 can be combined to form a guide rail. In this way, when the sprocket 12 rotates, the guide wheel 113 passes through each support part 17 in turn. Under the action of the guide wheel 113, the force transmission part 19 can move relative to the seat body 11 according to the undulation of the guide rail, and then the shift lever 31 moves correspondingly under the action of the force transmission part 19.

[0044] The position of the support part 17 relative to the chain link 114 and the fixed angle of the support part 17 can be adjusted, so that the shape of the guide rail can be adjusted as needed, and further the movement path of the force transmission part 19 relative to the seat body 11 can be adjusted.

[0045] The test platform of the embodiment of the present application can perform fatigue tests on the shift mechanism 3, that is, by continuously and reciprocally moving the shift lever 31, the fatigue life of the shift lever 31 is tested. It can also perform functional tests on the shift mechanism 3, that is, by moving the shift lever 31, it is judged whether the corresponding functions of the shift mechanism 3 are correct when the shift lever 31 is in different positions.

[0046] See Figure 2, in some embodiments, the link 114 is provided with a limiting portion 115, the limiting portion 115 is provided with a first through hole, the moving portion 15 is inserted through the first through hole, the moving portion 15 is threadedly connected with two threaded portions 116, and the limiting portion 115 is arranged between the two threaded portions 116.

[0047] The two threaded portions 116 cooperate to enable the position of the moving portion 15 relative to the link 114 to be adjusted. Specifically, by rotating the two threaded portions 116, the two threaded portions 116 can clamp the limiting portion 115, and at this time, the position of the moving portion 15 relative to the link 114 is fixed. On the contrary, rotate one of the threaded portions 116 to separate the two threaded portions 116, and then the moving portion 15 can move relative to the link 114. Finally, rotate the other threaded portion 116 to clamp the limiting portion 115 again, and at this time, the moving portion 15 is fixed again.

[0048] See Figure 1 and Figure 2 , in some embodiments, the moving portion 15 is provided with a second through hole, the axis of the second through hole is perpendicular to the second direction, and the driving assembly 1 further includes a flexible ring body 18, and the flexible ring body 18 is sequentially inserted through the second through holes of the respective moving portions 15.

[0049] The flexible ring body 18 is made of an elastic material.

[0050] The flexible ring body 18 is sequentially inserted through the respective second through holes of the moving portion 15. On the one hand, it can improve the position adjustment efficiency of the multiple moving portions 15. For example, there are multiple intermediate links between link A and link B. When adjusting the position of the moving portion 15 of link A, in order to enable the docking between the supporting portions 17, starting from the intermediate link close to link A, the positions of the moving portions 15 of each intermediate link may need to be adjusted one by one, which makes the adjustment workload large. At this time, the moving portion 15 of link B can be kept in the locked state, and the moving portions 15 of link A and each intermediate link are unlocked. At this time, when moving the moving portion 15 of link A, the moving portions 15 of other intermediate links can move synchronously, and the moving distance of the moving portion 15 of the intermediate link closer to link B is smaller. After the adjustment is completed, first lock the moving portion 15 of link A, and then sequentially lock the moving portions 15 of each intermediate link, which can improve the position adjustment efficiency of the moving portion 15. On the other hand, the flexible ring body 18 is made of an elastic material. When the position of the moving portion 15 relative to the link 114 is adjusted, the flexible ring body 18 can generate an axial force on the threaded portion 116, which can play a role in preventing loosening of the threaded portion 116, thereby improving the fixing reliability of the moving portion 15. On the other hand, the flexible ring body 18 can generate a force on the chain 13 towards the sprocket 12, which can improve the stability of the movement of the chain 13 and reduce the risk of the chain 13 disengaging from the sprocket 12.

[0051] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In some embodiments, the moving part 15 is provided with a recess, and a protruding part 125 is arranged in the recess. The locking component includes a sleeve body 120 and two inserting parts 124. The two inserting parts 124 are inserted between the inner peripheral wall of the recess and the outer peripheral wall of the protruding part 125. The two inserting parts 124 are arranged oppositely along the radial direction of the recess. One side of the two inserting parts 124 away from the recess forms a frustum-shaped structure. The sleeve body 120 is sleeved on the outer peripheral walls of the two inserting parts 124, and the sleeve body 120 is threadedly connected with the two inserting parts 124. The supporting part 17 is arranged between the two inserting parts 124.

[0052] There is a gap between the protruding part 125 and the recess, so that an annular groove can be formed between the outer wall of the protruding part 125 and the inner wall of the recess.

[0053] The two inserting parts 124 are inserted between the inner peripheral wall of the recess and the outer peripheral wall of the protruding part 125, so that the two inserting parts 124 can move in the annular groove, and further the two inserting parts 124 can rotate around the recess.

[0054] The part of the two inserting parts 124 inserted into the annular groove can be an arc-shaped plate structure.

[0055] The supporting part 17 is arranged between the two inserting parts 124, so that the supporting part 17 can support the two inserting parts 124, and further the supporting part 17 and the two inserting parts 124 can rotate around the protruding part 125 more smoothly. And the supporting part 17 can move horizontally between the two inserting parts 124 to adjust the distance between adjacent two supporting parts 17.

[0056] After the position of the supporting part 17 is adjusted, rotate the sleeve body 120. Since one side of the two inserting parts 124 away from the recess forms a frustum-shaped structure, as the sleeve body 120 gradually approaches the protruding part 125, the two inserting parts 124 close together, clamping the protruding part 125 and at the same time clamping the supporting part 17, so that the supporting part 17 can be locked. Further, such a setting also has the advantage of facilitating the disassembly of the supporting part 17.

[0057] See Figure 5 and Figure 6In some embodiments, the support portion 17 is bent, and the support portion 17 includes a first segment 117 and a second segment 118 arranged in parallel. The first segment 117 is provided with a first bent portion 122, and the second segment 118 is provided with a second bent portion 123. The first bent portion 122 and the second bent portion 123 are arranged between the two inserted portions 124, and the first bent portion 122 is against the second bent portion 123.

[0058] The support portion 17 may be made of an elastic material. Since the torque required to move the lever 31 is relatively small, the support portion 17 is made of an elastic material to meet the test requirements.

[0059] The support portion 17 is bent, that is, the middle portion of the support portion 17 is folded in half, so that the support portion 17 can form a first segment 117 and a second segment 118 , and one side of the support portion 17 is opened.

[0060] The first curved portion 122 is in a state where the convex side faces the second curved portion 123 , and the second curved portion 123 is in a state where the convex side faces the first curved portion 122 .

[0061] When the two insertion portions 124 are closed, the insertion portions 124 apply pressure to the first curved portion 122 and the second curved portion 123, and the bending amplitude of the first curved portion 122 and the second curved portion 123 is reduced. This arrangement, on the one hand, increases the overall length of the support portion 17, thereby allowing the two adjacent support portions 17 to be more closely docked, reducing the risk of the guide wheel 113 leaking out of the gap between the two support portions 17. On the other hand, the first segment 117 and the second segment 118 are closed, so that between the two adjacent support portions 17, the bent end of one support portion 17 can enter the opening of the other support portion 17 and be clamped by the first segment 117 and the second segment 118 of the support portion 17, so that the two adjacent support portions 17 can fit tightly. On the other hand, when the support portion 17 of a movable portion 15 needs to be adjusted, the sleeve 120 is rotated to unlock the two insertion portions 124. At this time, the first curved portion 122 and the second curved portion 123 are reset, and the overall length of the support portion 17 is reduced, reducing the risk of interference with the support portion 17 of the adjacent movable portion 15. On the other hand, when the chain link 114 moves to the sprocket 12, the opening allows the support portion 17 originally accommodated therein to be removed, so that the support portion 17 does not hinder the movement of the chain 13.

[0062] Furthermore, in the embodiment of the present application, the diameter of the guide wheel 113 can be reasonably set to reduce the risk of the guide wheel 113 leaking out of the gap of the support portion 17, and improve the stability of the guide wheel 113 moving along the guide rail.

[0063] See also Figure 4, in some embodiments, the support portion 17 further includes a third segment 119, the third segment 119 is configured to be bent in half at the middle, the two ends of the third segment 119 are gradually separated, and the two ends of the third segment 119 are respectively connected to the first segment 117 and the second segment 118.

[0064] Under the action of the third segment 119, the support portion 17 can form a bent structure.

[0065] The middle part of the third segment 119 is located at one end of the support portion 17, and the opening formed by the first segment 117 and the second segment 118 is located at the other end of the support portion 17.

[0066] Since the two ends of the third segment 119 are gradually separated, the distance between the first segment 117 and the second segment 118 can gradually increase from the side close to the third segment 119 to the side far from the third segment 119, and the formed opening is larger, facilitating the insertion of another support portion 17 therein. At the same time, under the action of the third segment 119, when the first segment 117 and the second segment 118 are closed, the middle part of the third segment 119 will not undergo large deformation, facilitating the insertion of this support portion 17 into the opening of another inserted support portion 17.

[0067] See Figure 6 , in some embodiments, the first segment 117 is for the guide wheel 113 to abut against. Two thickened areas 121 are provided on the side of the first segment 117 away from the second segment 118. The two thickened areas 121 are arranged on both sides of the first bending portion 122. A filling portion 126 is provided on the insertion portion 124 that cooperates with the first segment 117, and the filling portion 126 is arranged between the two thickened areas 121.

[0068] If the thickened areas 121 are not provided, since the support portion 17 is partially arranged between the two insertion portions 124, when the guide wheel 113 passes through the insertion portion 124, it is easy to produce jumps.

[0069] By providing the thickened areas 121, on the one hand, the support effect of the support portion 17 on the guide wheel 113 is improved. On the other hand, the filling portion 126 and the two thickened areas 121 cooperate to reduce the risk of jumps when the guide wheel 113 passes through the insertion portion 124.

[0070] See Figure 1 , in some embodiments, the drive assembly 1 further includes a mating portion 14, the mating portion 14 passes through the chain 13, and the mating portion 14 abuts against the inner peripheral wall of the chain 13.

[0071] The mating portion 14 is used to support the chain 13, so that when the chain 13 passes through the mating portion 14, the chain 13 can stably translate, thereby improving the stability of driving the transmission portion 19 to move.

[0072] See Figure 1 and Figure 3 In some embodiments, one side of the force transmission part 19 connected to the shift lever 31 includes two oppositely arranged connecting arms 111. The two connecting arms 111 are provided with third through holes, and the force transmission part 19 is provided with a closing part 112. The closing part 112 passes through the third through holes of the two connecting arms 111.

[0073] When the force transmission part 19 cooperates with the shift lever 31, the shift lever 31 is arranged between the two connecting arms 111.

[0074] The closing part 112 prevents the shift lever 31 from disengaging from between the two connecting arms 111.

[0075] Under the action of the third through hole, the closing part 112 can be detachably connected to the connecting arm 111.

[0076] The shift mechanism 3 may include a base. Commonly, the shift lever 31 can rotate relative to the base or translate relative to the base.

[0077] The connecting arm 111 and the closing part 112 enclose a frame structure. The shift lever 31 is arranged in the frame structure, and there is a gap between the shift lever 31 and the inner wall of the frame structure, so that the force transmission part 19 can be used for testing the above two types of shift levers 31. Further, a buffer pad can be sleeved on the outer wall of the shift lever 31 so that there is no clearance fit between the shift lever 31 and the frame structure.

[0078] See Figure 1 and Figure 3 In some embodiments, it further includes a fixing component 2. The fixing component 2 includes a ball seat 21, a ball head 22 and a fixing part 23. The ball seat 21 is provided with a spherical cavity. The ball head 22 is received in the spherical cavity. The fixing part 23 is connected to the ball head 22, and the shift mechanism 3 is connected to the fixing part 23.

[0079] The ball head 22 is received in the spherical cavity, so that the ball head 22 can rotate relative to the ball seat 21.

[0080] The fixing part 23 is used to connect the shift mechanism 3 to the ball head 22, so that the installation angle of the shift mechanism 3 can be adjusted as needed.

[0081] The ball seat 21 may be provided with a limiting structure for unlocking or locking the ball head 22. Before testing, unlock the ball head 22 so that the shift mechanism 3 can be installed in a suitable position. During the testing process, the ball head 22 can be locked so that the position of the shift mechanism 3 can be fixed.

[0082] The above embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, variations, modifications, and substitutions made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
