Figure 2 This is a schematic diagram of the first component and the clamping structure provided in Example 1 of the present application. Figure 3 A schematic diagram of the clamping structure provided in Example 1 of the present application.

[0032] like Figure 1-Figure 3As shown, this embodiment provides a pull rope connecting device, including a first pull rope 1, a second pull rope 11, and a clamping structure 2 connecting the first pull rope 1 and the second pull rope 11, the clamping structure 2 includes a sleeve 21, and a clamping portion 22 plugged into the sleeve 21, the clamping portion 22 moves along the axial direction of the sleeve 21 and locks or releases therefrom, one end of the first pull rope 1 is connected to the clamping structure 2, and the other end of the first pull rope 1 is provided with a first fixing portion 12, one end of the second pull rope 11 is connected to the clamping structure 2, and the other end of the second pull rope 11 is provided with a second fixing portion 13 for connection and fixation.

[0033] The first fixing portion 12 is detachably connected to the first component 3, and the second fixing portion 13 is detachably connected to the second component 4. The first component 3 provided in this embodiment is a trim panel, and the second component 4 is a frame body. The trim panel is a back door trim panel in the vehicle, and the frame body is a coat rack.

[0034] The first component 3 and the first pull rope 1 can be connected by means of clamping, hanging, screwing, etc. In this embodiment, a positioning column 31 is provided on the first component 3, and the first fixing part 12 is set as a ring. The ring can hang the first pull rope 1 to a specified position. The first fixing part 12 is correspondingly hung with the positioning column 31. The first pull rope 1 is in a suspended state relative to the positioning column 31. The positioning column 31 occupies a small space of the first component 3, and the first pull rope 1 in the suspended state further reduces the space occupation. The method of removing the first pull rope 1 from the positioning column 31 is simple and easy to operate. The second pull rope 11 and the second component 4 can be connected by means of clamping, hanging, screwing, etc. In this embodiment, a positioning hole 41 is provided on the second component 4, and the second fixing part 13 is set as a fixing block. The fixing block bears weight and force and acts on the second pull rope 11. The end of the second pull rope 11 passes through the positioning hole 41, and the fixing block abuts against the second component 4. The size of the fixing block is larger than the size of the positioning hole 41, so that the frame can be stably suspended by the second pull rope 11.

[0035] A clamping structure 2 is provided between the first pull rope 1 and the second pull rope 11, and the first pull rope 1 is connected to the sleeve 21 of the clamping structure 2, or the first pull rope 1 is connected to the clamping portion 22 of the clamping structure 2; correspondingly, the second pull rope 11 is connected to the clamping portion 22 of the clamping structure 2, or the second pull rope 11 is connected to the sleeve 21 of the clamping structure 2.

[0036] By arranging a first pull rope 1 at one end of the clamping structure 2 and a second pull rope 11 at the other end of the clamping structure 2, it is convenient to connect the first component 3 and the second component 4, so that the first component 3 and the second component 4 are in a state of relative suspension, and the space volume occupied is effectively reduced; the first pull rope 1 and the first component 3 are detachably connected, and the second pull rope 11 and the second component 4 are detachably connected, and the assembly is simple and the operation is convenient; the clamping portion 22 of the clamping structure 2 is adapted to the sleeve 21, and when the load-bearing portion is large, the locking position of the clamping structure 2 is loosened, so as to protect the first component 3 and the second component 4 and avoid cracking and damage of the first component 3 and the second component 4. When the load-bearing portion does not exceed the necessary limit, the clamping structure 2 can automatically lock and position to play a connecting role. The overall device has good safety performance, is conducive to extending the service life, and is not easy to be damaged.

[0037] Embodiment 2

[0038] This embodiment optimizes a pull rope connection device based on the above embodiment, and in particular provides a specific implementation method of a clamping structure:

[0039] The clamping structure 2 comprises a sleeve 21 and a clamping portion 22 plugged into the sleeve 21 . A plurality of windows 23 for limiting the clamping portion 22 are arranged in the sleeve 21 .

[0040] Figure 4 This is an oblique cross-sectional diagram of the clamping structure provided in the second embodiment of the present application. Figure 5 This is a schematic diagram of the structure of the clamping portion provided in Example 2 of the present application.

[0041] like Figure 4 , Figure 5 As shown, the sleeve 21 can be a cylindrical barrel structure, a square cylindrical barrel structure or a barrel structure of other shapes. In this embodiment, the sleeve 21 is a cylindrical barrel structure, the sleeve 21 has a hollow inner cavity, one end of the sleeve 21 is a closed end, and the other end of the sleeve 21 is an opening, and the opening corresponds to the clamping portion 22.

[0042] The closed end of the sleeve 21 is connected to the first pull rope 1. Specifically, the first pull rope 1 is arranged at the center position of the closed end of the sleeve 21, so that when the first pull rope 1 is in a suspended state, the traction force of the first pull rope 1 acts on the center setting of the sleeve 21 to keep the sleeve 21 in a balanced and stable state when subjected to force.

[0043] The clamping portion 22 includes a clamping seat 24, and a plurality of clamping claws 25 disposed at the end of the clamping seat 24 and arranged concentrically around the clamping seat 24; the plurality of clamping claws 25 are arranged at equally divided positions of the same circumference, and in this embodiment, the number of the plurality of clamping claws 25 is three, and the angle between adjacent clamping claws 25 is 120°. Correspondingly, windows 23 corresponding to the clamping claws 25 are disposed on the outer wall of the sleeve 21, and the plurality of windows 23 are arranged around the outer wall of the sleeve 21, specifically three windows 23.

[0044] The end of the clamping seat 24 away from the clamping claw 25 is connected to the second pull rope 11. Specifically, the second pull rope 11 is set at the center position of the clamping seat 24. The bearing force of the second pull rope 11 acts on the center position of the clamping seat 24 to keep the clamping seat 24 in a balanced and stable state when subjected to force.

[0045] The claw 25 includes an elastic portion 26 and a tapered portion 27 connected to the elastic portion 26; the elastic portion 26 is connected to the clamping seat 24, the tapered portion 27 is located at the end of the elastic portion 26 away from the clamping seat 24, the outer wall of the tapered portion 27 is an inclined surface 28, the tips of the tapered portions 27 of several claws 25 are arranged to gather toward the center of the circle, and the tips of the tapered portions 27 of several claws 25 are in the inner cavity of the sleeve 21, so that the claw 25 can be easily slid and guided and loosened from the sleeve 21. The bottom end of the tapered portion 27 is correspondingly clamped with the edge of the window 23 to achieve the limiting effect of the tapered portion 27.

[0046] The diameter of the clamping seat 24 is adapted to the diameter of the inner cavity of the sleeve 21 . The diameter of the circle enclosed by the plurality of elastic parts 26 is smaller than the diameter of the clamping seat 24 . When the plurality of claws 25 enter the inner cavity of the sleeve 21 , the plurality of elastic parts 26 have a certain elastic deformation space.

[0047] When the clamping portion 22 enters the inner cavity of the sleeve 21 and moves into position, the tapered portion 27 of the claw 25 is limited in the window 23 to form a locking relationship. When the clamping portion 22 bears a large load, the tapered portion 27 of the claw 25 can still be loosened from the window 23. According to the load-bearing design of the clamping portion 22, the gap between the clamping seat 24 and the inner cavity of the sleeve 21 is controllable, and the matching gap between the tapered portion 27 and the window 23 is controllable, thereby limiting the matching tightness of the clamping portion 22 and the sleeve 21. For example, when the load-bearing of the clamping portion 22 exceeds 5kg, the clamping portion 22 and the sleeve 21 are loosened.

[0048] The locking, positioning and loosening functions of the snap-fit ​​structure 2 prevent the first component 3 or the second component 4 from breaking and the risk of the first component 3 falling off after the first component 3 and the second component 4 are connected in sections when the load exceeds a certain weight.
