In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0035] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, term "installation", "link", "connection" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through the intermediate medium, can be two elements inside the communication.For ordinary skilled in the art, the above-mentioned terms can be understood in the specific meaning of the utility model according to specific circumstances.

[0036] As Figures 1 to 4 Shown, in an embodiment, test tool 10 includes: first carrier 1, second carrier 2 and drive assembly 3;Wherein, first carrier 1 is provided with first connecting area 11, and first connecting area 11 is used to install sealing strip 20;Second carrier 2 is provided with second connecting area 21, and second connecting area 21 is used to install counterhand 30;Drive assembly 3 is used to drive at least one of first carrier 1 and second carrier 2 reciprocating movement along the first direction, so that first carrier 1 and second carrier 2 can approach or move away along the first direction;Wherein, when first carrier 1 and second carrier 2 approach along the first direction, counterhand 30 connected to second connecting area 21 can press sealing strip 20 connected to first connecting area 11. Figure 1 Shown in the direction, the first direction is parallel to Z axis.

[0037] First carrier 1 and second carrier 2 approach or move away along the first direction can mean: first carrier 1 is stationary, and second carrier 2 reciprocating movement along the first direction to approach or move away from first carrier 1;Or, second carrier 2 is stationary, and first carrier 1 reciprocating movement along the first direction to approach or move away from second carrier 2;Or, first carrier 1 and second carrier 2 can move towards each other, so that the distance between them decreases, realizing the approach of two, and first carrier 1 and second carrier 2 can move away from each other, so that the distance between them increases, realizing the moving away of two.

[0038] In the embodiment, when drive assembly 3 drives first carrier 1 and second carrier 2 to approach, so that counterhand 30 connected to second connecting area 21 presses sealing strip 20 connected to first connecting area 11, the scene that counterhand 30 presses sealing strip 20 when closing piece closes can be simulated, so that test tool 10 can simulate the actual use condition of sealing strip 20 well, and improve the detection effect of sealing strip 20.

[0039] In addition, when drive assembly 3 drives first carrier 1 and second carrier 2 to move away, so that counterhand 30 connected to second connecting area 21 moves away from sealing strip 20 of first connecting area 11, the scene that closing piece opens can be simulated at this time.

[0040] Furthermore, in the first direction, the first connecting area 11 and the second connecting area 21 are opposite each other, such that when the first carrier 1 and the second carrier 2 approach each other in the first direction, the opponent 30 connected to the second connecting area 21 can press the sealing strip 20 connected to the first connecting area 11.

[0041] In the first direction, the first connecting area 11 and the second connecting area 21 are opposite each other, which means that in an orthographic projection onto a plane perpendicular to the first direction, the projections of the first connecting area 11 and the second connecting area 21 at least partially overlap. In one application scenario, the first direction can be a vertical direction. The first support member 1 can be located below the second support member 2.

[0042] It should be understood that the connection of the sealing strip 20 in the first connection area 11 is detachable, and similarly, the connection of the hand piece 30 in the second connection area 21 is also detachable, so that the test fixture 10 can test different sealing strips 20.

[0043] Furthermore, in existing technologies, after testing the sealing strip using friction, the sealing strip is installed on the opening and closing components during manufacturing for further testing to simulate a full vehicle opening and closing test, commonly known as an "opening and closing durability test." However, by the time the opening and closing durability test is conducted, the vehicle is already close to mass production, the product is relatively mature, and the verification of the sealing strip material is nearing completion. If problems such as wear or exudation are found at this stage, the sealing strip material needs to be readjusted and re-verified, which requires a significant amount of time and expense. The setup in this embodiment effectively avoids these problems and helps shorten the vehicle development cycle.

[0044] like Figure 1 and Figure 3 As shown, in one embodiment, the test fixture 10 further includes a fixing member 4, which is connected to the first bearing member 1. The fixing member 4 is provided with a first snap-fit ​​structure 41, which is used to cooperate with a second snap-fit ​​structure on the sealing strip 20, so that the sealing strip 20 is installed in the first connection area 11. Through the cooperation of the first snap-fit ​​structure 41 and the second snap-fit ​​structure, the sealing strip 20 can be detachably connected to the first connection area 11 by snap-fit, thereby facilitating the installation of the sealing strip 20 in the first connection area 11.

[0045] In one embodiment, the second snap-fit ​​structure on the sealing strip 20 is a slot, in which case the first snap-fit ​​structure 41 can be a block. Of course, in other embodiments, if the second snap-fit ​​structure on the sealing strip 20 is a block, then the first snap-fit ​​structure 41 can be a slot.

[0046] In an embodiment, the fixing member 4 is detachably connected with the first carrier 1. In this way, the fixing member 4 matched with the seal 20 to be tested can be installed on the first carrier 1 according to the type of the seal 20 to be tested, so that the adaptability of the detection work can be improved. In an embodiment, the fixing member 4 can be connected with the first carrier 1 by a connecting member such as a bolt, so as to realize the detachable connection of the fixing member 4 with the first carrier 1.

[0047] As shown in Figure 3 In an embodiment, the test tool 10 further comprises a guide assembly 5 connected with the first carrier 1 and the second carrier 2 respectively, for guiding the movement of the first carrier 1 and the second carrier 2 along the first direction to approach or move away from each other.

[0048] In an embodiment, the guide assembly 5 can comprise a guide column, which can be connected with the first carrier 1, and the second carrier 2 is provided with a guide hole, and the guide column is arranged in the guide hole. When the first carrier 1 and the second carrier 2 move along the first direction to approach or move away from each other, the guide hole wall and the guide column can guide the movement. Of course, the guide assembly 5 can also be designed in other existing ways, which is not limited in the embodiment.

[0049] As shown in Figure 2 In an embodiment, the driving assembly 3 comprises a driving member 31 arranged on the first carrier 1 and connected with the second carrier 2, and the driving member 31 is used to drive the second carrier 2 to move along the first direction. When the opening and closing member opens or closes, the counter member 30 is usually driven to move, and the seal 20 is not moved. Therefore, the arrangement of the embodiment can be more consistent with the actual working environment of the seal 20. The driving member 31 can be a cylinder, an electric cylinder, an oil cylinder or an electromagnet, which can drive the object to move linearly and reciprocally.

[0050] In an embodiment, the driving member 31 is detachably connected with the second carrier 2. In this way, the seal 20 and the counter member 30 can be conveniently installed on the test tool 10.

[0051] As shown in Figure 2 In an embodiment, the first carrier 1 is provided with a receiving groove 12, and the driving member 31 is arranged in the receiving groove 12. In the first direction, the receiving groove 12 penetrates to the surface of the first carrier 1 close to the second carrier 2. The driving member 31 can extend from the receiving groove 12 to the side of the first carrier 1 close to the second carrier 2.

[0052] As shown in Figure 1 and Figure 4As shown, in an embodiment, in the first direction, the second carrier 2 is provided with a connecting groove 22 on the surface close to the first carrier 1, and the connecting groove 22 and the second connecting area 21 are spaced apart along the second direction; along the second direction, the connecting groove 22 unidirectionally penetrates the second carrier 2; the driving member 31 can move into or out of the connecting groove 22 along the second direction; when the driving member 31 moves into the connecting groove 22, the driving member 31 can be connected with the second carrier 2; when the driving member 31 moves out of the connecting groove 22, the driving member 31 can be detached from the second carrier 2, that is, the driving member 31 can realize disassembly from the second carrier 2; the second direction is perpendicular to the first direction, and in the direction shown, the second direction is parallel to the X axis. In this way, the disassembly and connection of the driving member 31 and the second carrier 2 are more convenient. Figure 1 In the direction shown, the second direction is parallel to the X axis. In this way, the disassembly and connection of the driving member 31 and the second carrier 2 are more convenient.

[0053] In the direction shown, the second direction is parallel to the X axis. In this way, the disassembly and connection of the driving member 31 and the second carrier 2 are more convenient.

[0054] It should be understood that the connecting groove 22 and the second connecting area 21 are spaced apart along the second direction, and along the second direction, the connecting groove 22 unidirectionally penetrates the second carrier 2, which means that the connecting groove 22 does not extend to the second connecting area 21, so that the driving member 31 can be prevented from moving along the connecting groove 22 to the second connecting area 21, and the driving member 31 can be prevented from interfering with the opponent member 30 connected to the second connecting area 21.

[0055] In addition, when the driving member 31 is an oil cylinder or a gas cylinder, the driving member 31 is connected to the first carrier 1, which actually means that the cylinder body of the driving member 31 is connected to the first carrier 1, and the driving member 31 is connected to the second carrier 2, which actually means that the piston rod of the driving member 31 is connected to the second carrier 2. At this time, the driving member 31 moving into or out of the connecting groove 22 mainly means that the piston rod of the driving member 31 moves into or out of the connecting groove 22.

[0056] As shown, in an embodiment, in the first direction, the second carrier 2 is provided with a connecting groove 22 on the surface close to the first carrier 1, and the connecting groove 22 and the second connecting area 21 are spaced apart along the second direction; along the second direction, the connecting groove 22 unidirectionally penetrates the second carrier 2; the driving member 31 can move into or out of the connecting groove 22 along the second direction; when the driving member 31 moves into the connecting groove 22, the driving member 31 can be connected with the second carrier 2; when the driving member 31 moves out of the connecting groove 22, the driving member 31 can be detached from the second carrier 2, that is, the driving member 31 can realize disassembly from the second carrier 2; the second direction is perpendicular to the first direction, and in the direction shown, the second direction is parallel to the X axis. In this way, the disassembly and connection of the driving member 31 and the second carrier 2 are more convenient. Figures 1 to 4As shown in the figure, in an embodiment, along the first direction, the connecting groove 22 penetrates through the surface of the second carrier 2 away from the first carrier 1; the driving assembly 3 further comprises a resisting member 32 connected to the driving member 31; the second carrier 2 is provided with a limiting structure 24; the test tool 10 further comprises a pressing member 6 and a locking member; the locking member connects the pressing member 6 and the second carrier 2, so that the pressing member 6 and the second carrier 2 have a locked state and a released state; when the pressing member 6 and the second carrier 2 are in the locked state and the driving member 31 is located in the connecting groove 22, the pressing member 6 can press the resisting member 32 against the limiting structure 24, so as to connect the driving member 31 and the second carrier 2 together; when the pressing member 6 and the second carrier 2 are in the released state, the driving member 31 can move into or out of the connecting groove 22 along the second direction. In this way, the installation and disassembly of the driving member 31 and the second carrier 2 are more convenient.

[0057] In an embodiment, the second carrier 2 is provided with a threaded hole (defined as a first threaded hole), and the pressing member 6 is provided with a through hole (defined as a first through hole) penetrating through the pressing member 6 along the first direction. The pressing member 6 can be a bolt (defined as a first bolt), which penetrates through the pressing member 6 from the first through hole and is screwed into the first threaded hole, so as to connect the pressing member 6 to the second carrier 2. At the same time, by rotating the first bolt into the first threaded hole to a certain depth, the pressing member 6 and the second carrier 2 can be switched between the locked state and the released state.

[0058] As shown in the figures, Figure 1 and Figure 2 In an embodiment, the resisting member 32 and the limiting structure 24 are both located in the connecting groove 22, wherein, along the first direction and along the direction from the first carrier 1 to the second carrier 2, the connecting groove 22 comprises a first segment groove 221 and a second segment groove 222, wherein the first segment groove 221 and the second segment groove 222 are communicated, the width of the first segment groove 221 is smaller than that of the second segment groove 222, and a first step surface is formed between them, which is the resisting structure; the resisting member 32 protrudes from the part of the driving member 31 extending into the connecting groove 22 along the width direction of the first segment groove 221; after assembly, the resisting member 32 is located in the second segment groove 222, and the pressing member 6 can press the resisting member 32 against the first step surface.

[0059] When the part of the driving member 31 extending into the connecting groove 22 is a piston rod, the resisting member 32 can be a stopper arranged at one end of the piston rod and protruding from the piston rod along the radial direction of the piston rod, wherein the stopper can also be a cylindrical structure, and at this time, the diameter of the stopper can be equal to that of the piston rod, and the two can be coaxially arranged. In addition, in the first direction, the first segment groove 221 can extend to the surface of the second carrier 2 close to the first carrier 1.

[0060] In addition, the width direction of the first section groove 221 and the width direction of the second section groove 222 are both the width direction of the connecting groove 22, the width direction of the connecting groove 22 is parallel to the third direction, and the third direction, the second direction and the first direction are perpendicular to each other. Figure 1 In the shown direction, the third direction is parallel to the Y axis.

[0061] In an embodiment, the connecting groove 22 further comprises a third section groove 223, which is located on the side of the second section groove 222 away from the first section groove 221 along the first direction, the third section groove 223 is in communication with the second section groove 222, and the width of the second section groove 222 is smaller than the width of the third section groove 223, thereby forming a second step surface therebetween. When the pressing member 6 presses the stop member 32 against the first step surface, the stop member 32 can protrude from the second step surface or be flush with the second step surface along the direction from the first step surface to the second step surface. The pressing member 6 is located in the third section groove 223, and the locking member can be connected to the second step surface. Specifically, the first threaded hole is arranged on the second step surface.

[0062] In addition, in the first direction, the third section groove 223 can extend through to the surface of the second carrier 2 away from the first carrier 1. Of course, when the connecting groove 22 does not comprise the third section groove 223, the second section groove 222 can extend through to the surface of the second carrier 2 away from the first carrier 1, and in this case, the first threaded hole can be arranged on the surface of the second carrier 2 away from the first carrier 1.

[0063] As shown in FIGS. 1 and 2, the first carrier 1 comprises a connecting groove 22, which is arranged on the surface of the first carrier 1 away from the second carrier 2. Figure 1 and Figure 3 In an embodiment, the first carrier 1 is provided with a first mounting groove 13 on the surface thereof close to the second carrier 2 in the first direction, and the first connecting area 11 is located on the bottom surface of the first mounting groove 13. This arrangement can effectively prevent foreign objects from colliding with the sealing strip 20 mounted on the first connecting area 11.

[0064] In addition, in an embodiment, the first mounting groove 13 extends through the first carrier 1 in the third direction in one direction or in two directions. In this way, water or sand can be injected into the first mounting groove 13 to simulate a more realistic working scenario.

[0065] The first mounting groove 13 extends through the first carrier 1 in the third direction in one direction, which means that the first mounting groove 13 extends along the third direction, and one end of the first mounting groove 13 extends to the outer surface of the first carrier 1 to form an opening on the outer surface of the first carrier 1. The first mounting groove 13 extends through the first carrier 1 in the third direction in two directions, which means that the first mounting groove 13 extends along the third direction, and both ends of the first mounting groove 13 extend to the outer surface of the first carrier 1 to form openings on the outer surface of the first carrier 1.

[0066] When the first mounting groove 13 penetrates the first carrier 1 in the third direction, the first mounting groove 13 forms an opening on the surface of the first carrier 1 in the third direction, and the opening is defined as a first opening. In the working process, water or sand can be sprayed into the first mounting groove 13 from the first opening to simulate a more realistic working scenario.

[0067] As shown in the drawings, Figure 4 In an embodiment, the second carrier 2 is provided with a second mounting groove 23 on the surface close to the first carrier 1 in the first direction, and the second connecting area 21 is located on the bottom surface of the second mounting groove 23. This arrangement can effectively prevent foreign objects from colliding with the opponent piece 30 mounted on the second connecting area 21.

[0068] The opponent piece 30 can be detachably connected to the second carrier 2 by a connecting member such as a bolt. For example, the second connecting area 21 is provided with a threaded hole (defined as a second threaded hole), and the opponent piece 30 is provided with a through hole (defined as a second through hole). The bolt passes through the second through hole of the opponent piece 30 and is screwed into the second threaded hole, thereby connecting the opponent piece 30 to the second carrier 2. At this time, the second threaded hole is arranged on the bottom surface of the second mounting groove 23.

[0069] In addition, in the third direction, the second mounting groove 23 can not penetrate the second carrier 2.

[0070] As shown in the drawings, Figure 3 and Figure 4 In an embodiment, the first carrier 1 is detachably connected with a first limiting piece 7, and the second carrier 2 is detachably connected with a second limiting piece 8. When the first carrier 1 and the second carrier 2 are close to each other in the first direction, the first limiting piece 7 can abut against the second limiting piece 8 to limit the maximum displacement of the first carrier 1 and the second carrier 2 in the first direction. In this way, different thicknesses of the first limiting piece 7 and / or the second limiting piece 8 can be selected according to different compression requirements of the sealing strip 20. The thickness of the first limiting piece 7 refers to its size in the first direction, and the thickness of the second limiting piece 8 refers to its size in the first direction.

[0071] In addition, the first limiting piece 7 can be arranged on the surface of the first carrier 1 close to the second carrier 2 (i.e., the upper surface of the first carrier 1), and the second limiting piece 8 can be arranged on the surface of the second carrier 2 close to the first carrier 1 (i.e., the lower surface of the second carrier 2). In addition, the first limiting piece 7 can be a rectangular block or a cylindrical block, and the second limiting piece 8 can be a rectangular block or a cylindrical block.

[0072] In an embodiment, the first limit members 7 and the second limit members 8 can be multiple in number, and the first limit members 7 and the second limit members 8 can be one-to-one corresponding, and in operation, the first limit members 7 are used to abut against the corresponding second limit members 8. Moreover, each limit member can abut against the corresponding second limit member 8 at the same time.

[0073] In addition, in the second direction, each first limit member 7 is located on the two sides of the first connecting area 11, and each second limit member 8 is located on the two sides of the second connecting area 21.

[0074] In an embodiment, the first limit members 7 can be detachably connected to the first carrier 1 by bolts or the like, and the manner of realizing detachable connection with the first carrier can be the same as that of realizing detachable connection of the aforementioned hand member 30 with the second carrier 2. Similarly, the manner of realizing detachable connection of the second limit members 8 with the second carrier can be the same as that of realizing detachable connection of the aforementioned hand member 30 with the second carrier 2.

[0075] It should be understood that the above-mentioned related arrangements can also be replaced by other manners, for example: in other embodiments, the first limit members 7 are detachably connected to the first carrier 1, and when the first carrier 1 and the second carrier 2 are close to each other in the first direction, the first limit members 7 can abut against the second carrier 2 to limit the maximum displacement of the first carrier 1 and the second carrier 2 when they are close to each other in the first direction; at this time, the second carrier 2 is not provided with the second limit members 8. Alternatively, the second limit members 8 are detachably connected to the second carrier 2, and when the first carrier 1 and the second carrier 2 are close to each other in the first direction, the second limit members 8 can abut against the first carrier 1 to limit the maximum displacement of the first carrier 1 and the second carrier 2 when they are close to each other in the first direction; at this time, the first carrier 1 is not provided with the first limit members 7.

[0076] In other embodiments, the second installation groove 23 can also be unidirectionally or bidirectionally penetrated through the second carrier 2 in the third direction, so as to spray water or sand or the like from the second installation groove 23 to the sealing strip 20. The second installation groove 23 is unidirectionally penetrated through the second carrier 2 in the third direction, which means that the second installation groove 23 extends in the third direction, and one end of the second installation groove 23 extends to the outer surface of the second carrier 2, so as to form an opening on the outer surface of the second carrier 2.

[0077] The second installation groove 23 is bidirectionally penetrated through the second carrier 2 in the third direction, which means that the second installation groove 23 extends in the third direction, and both ends of the second installation groove 23 extend to the outer surface of the second carrier 2, so as to form an opening on the outer surface of the second carrier 2.
