[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0041] against Figures 1 to 4 The gear selector cable assembly 100 shown includes a gear selector cable 101 and a gear shift cable 102. Both the gear selector cable 101 and the gear shift cable 102 include a sleeve 103 and a core rope 104 passing through the sleeve 103. Both ends of the sleeve 103 are provided with caps 105. Both ends of the core rope 104 extend out of the caps 105 and are provided with connectors 106. Both the caps 105 and the connectors 106 are plastic parts, and springs 107 are respectively provided in the caps 105 and the connectors 106.

[0042] When the selector shift cable assembly 100 leaves the factory, it needs to undergo quality inspections such as length testing (including sleeve 103 length testing, core rope 104 length testing and cable stroke testing), joint 106 tensile resistance testing, and spring 107 presence testing.

[0043] For this, please refer to Figures 5 to 7As shown, this embodiment provides a testing platform for a gear selector cable assembly, including a base plate 1 and a first positioning seat 2, a second positioning seat 3, a third positioning seat 4, and a fourth positioning seat 5 disposed on the base plate 1. The two first positioning seats 2 are used to fix the two caps 105 of the gear selector cable 101; the two second positioning seats 3 are used to fix the two caps 105 of the gear shift cable 102; the two third positioning seats 4 are used to fix one connector 106 of the gear selector cable 101 and one connector 106 of the gear shift cable 102; the two fourth positioning seats 5 are used to fix the other connector 106 of the gear selector cable 101 and the other connector 106 of the gear shift cable 102; metal detection sensors 6 are respectively disposed on the two first positioning seats 2, the two second positioning seats 3, the two third positioning seats 4, and the two fourth positioning seats 5, and the metal detection sensors 6 are used to detect whether there is a spring 107 in the corresponding cap 105 or connector 106.

[0044] Therefore, by mounting the selector cable 101 and shift cable 102 on the first positioning seat 2, the second positioning seat 3, the third positioning seat 4, and the fourth positioning seat 5 respectively, the selector cable 101 and shift cable 102 can be positioned quickly at the same time, thereby realizing the rapid detection of the length of the corresponding sleeve 103, the length of the core rope 104, and the cable stroke. In addition, by using the metal detection sensor 6 on each positioning seat to detect each spring 107 in the cap 105 and the connector 106, it is possible to quickly determine whether there are any missing springs 107 in multiple locations, which greatly improves the detection efficiency, reduces the detection difficulty, and improves the reliability of the detection results.

[0045] Optionally, the third positioning seat 4 is provided with a first groove that is adapted to the shape of the joint 106 of the gear selection cable 101 or the joint 106 of the gear shift cable 102. The third positioning seat 4 can switch between a first height position and a second height position. When the third positioning seat 4 is in the first height position, the core rope 104 can move freely axially relative to the sleeve 103. When the third positioning seat 4 is in the second height position, it is used to detect whether the joint 106 can be accurately embedded in the first groove, so as to calibrate the initial position of the joint 106 when the core rope 104 is not under force.

[0046] Therefore, by raising the third positioning seat 4 to the second height position, it can be determined whether the joint 106 and the first groove are accurately nested. This allows for quick calibration of the initial positions of the core rope 104 of the selector cable 101 and the core rope 104 of the shift cable 102 under no-stress conditions. This is especially convenient when batch testing of cable products of the same model. When the third positioning seat 4 is lowered to the first height position, the core rope 104 can be controlled to move axially relative to the sleeve 103 for subsequent cable stroke testing and tensile resistance testing.

[0047] Furthermore, a connecting plate 7 is provided on one side of the first positioning seat 2 or one side of the second positioning seat 3. A guide rail 8 is provided on the connecting plate 7. A first slider 9 that can move and lock is provided on the guide rail 8. A lifting cylinder 10 is provided on the first slider 9. The third positioning seat 4 is installed on the output rod of the lifting cylinder 10.

[0048] Therefore, by driving the third positioning seat 4 to switch positions through the lifting cylinder 10, and by adjusting the relative position of the first slider 9 on the guide rail 8, different specifications of gear selection cable 101 and gear shift cable 102 can be adapted, thereby improving the versatility of the gear selection cable assembly testing platform.

[0049] Optionally, a first slide rail 11 is provided on the base plate 1 and directly below the fourth positioning seat 5. A second slider 12 and a third slider 13 are provided on the first slide rail 11. A force sensor 14 is provided between the second slider 12 and the third slider 13. The fourth positioning seat 5 is mounted on the third slider 13. The fourth positioning seat 5 is provided with a second groove that is adapted to the shape of the joint 106 of the shift cable 101 or the joint 106 of the shift cable 102. A tensile testing mechanism is provided on one side of the first slide rail 11. The tensile testing mechanism is used to drive the second slider 12 to move along the first slide rail 11, thereby driving the third slider 13 to move the core rope 104 axially relative to the sleeve 103.

[0050] Thus, the fourth positioning seat 5 is driven to move relative to the first positioning seat 2 and the second positioning seat 3 by the tensile testing mechanism, thereby controlling the axial movement of the core rope 104 to complete the stroke and tensile test. The force sensor 14 can directly reflect the tensile resistance.

[0051] Furthermore, the tensile testing mechanism includes a drive motor 15, a lead screw 16, and a nut 17. The lead screw 16 is arranged parallel to the first slide rail 11. The drive motor 15 is used to drive the lead screw 16 to rotate. The nut 17 is threadedly engaged with the lead screw 16 and is fixedly connected to the second slider 12.

[0052] Thus, through the transmission and cooperation of the lead screw 16 and nut 17, the second slider 12 and the third slider 13 move precisely back and forth on the first slide rail 11, ensuring detection accuracy.

[0053] Furthermore, a displacement sensor 18 is provided on one side of the first slide rail 11, and a stroke block 19 is provided on the third slider 13. The pull rod of the displacement sensor 18 is connected to the stroke block 19.

[0054] Therefore, the displacement sensor 18 can detect the movement of the core rope 104 in real time, and stop the drive in time when an abnormality occurs to avoid damage to the gear selection cable 101 and the gear shift cable 102.

[0055] Optionally, the first positioning seat 2 is provided with a third groove for the cap 105 of the limit selection cable 101. A second slide rail 20 is provided on the base plate 1 and directly below the first positioning seat 2. A fourth slider 21 that can move and lock is provided on the second slide rail 20. The first positioning seat 2 is mounted on the fourth slider 21. The distance between the two first positioning seats 2 is adjustable so that the sleeve 103 of the selection cable 101 remains straight. In particular, the second slide rail 20 and the corresponding first slide rail 11 can share a track.

[0056] Therefore, the two first positioning seats 2 move relative to each other to match the sleeves 103 of the selector cable 101 of different specifications, and the two first positioning seats 2 cooperate to check the length of the sleeves 103 of the selector cable 101.

[0057] Optionally, the second positioning seat 3 is provided with a fourth groove for the cap 105 of the limit shift cable 102. A third slide rail 22 is provided on the base plate 1 and directly below the second positioning seat 3. A fifth slider 23 that can move and lock is provided on the third slide rail 22. The second positioning seat 3 is mounted on the fifth slider 23. The distance between the two second positioning seats 3 is adjustable so that the sleeve 103 of the shift cable 102 remains straight. In particular, the third slide rail 22 and the corresponding first slide rail 11 can share a track.

[0058] Therefore, the two second positioning seats 3 move relative to each other to match the sleeves 103 of the shift cable 102 of different specifications, and the two second positioning seats 3 cooperate to check the length of the sleeves 103 of the shift cable 102.

[0059] Optionally, a dust cover 108 is connected between the gear selector cable 101 and the gear shift cable 102, and a limiting block 24 is provided on the base plate 1 to position and support the dust cover 108.

[0060] Therefore, by using the limiting block 24 to position some features (such as the dust cover 108) on the gear shift cable assembly 100, the gear shift cable assembly 100 can be quickly and accurately placed on the gear shift cable assembly testing platform, ensuring the accuracy of subsequent test results.

[0061] Optionally, the base plate 1 is provided with a support plate 25 that supports the middle part of the sleeve 103 of the gear selection cable 101 and the middle part of the sleeve 103 of the gear shift cable 102.

[0062] Therefore, by supporting the sleeve 103 with the support plate 25, the middle part of the sleeve 103 is prevented from sagging, which would affect the smooth movement of the core rope 104 in the sleeve 103 and thus affect the test results.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
