[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Reference below Figure 1-Figure 3 The pull wire assembly 2 of the bonnet lock 1 according to the embodiment of the utility model is described, and the pull wire assembly 2 of the bonnet lock 1 is installed on a vehicle.

[0031] According to the first aspect of the embodiment of the utility model, the pull wire assembly 2 of the hood lock 1 may include: a protective tube 10, a pull wire 20 and a dust cover 30. The pull wire 20 is passed through the protective tube 10. The pull wire 20 is fixed with a limit block 21. The limit block 21 is spaced apart from the protective tube 10 along the length direction of the pull wire 20. The dust cover 30 is sleeved on the pull wire 20. The dust cover 30 is connected between the protective tube 10 and the limit block 21, and the dust cover 30 is fixedly connected to the limit block 21.

[0032] It should be noted that in the prior art, there is relative movement between the pull wire and the dust cover, and complete sealing cannot be achieved. In winter, if ice forms on the pull wire, the ice on the pull wire and the dust cover interfere with each other, forming resistance, making it impossible to pull the pull wire and unlock the hood lock, which can easily cause vehicle failure.

[0033] Based on this, the embodiment of the present application proposes a cable assembly 2 of a hood lock 1, which is provided with a protective tube 10, a cable 20 and a dust cover 30, such as Figure 2 As shown, the pull wire 20 is passed through the protective tube 10, and the pull wire 20 can move relative to the protective tube 10. The pull wire 20 can be a metal wire. A limit block 21 is fixed on the pull wire 20. The limit block 21 can be a metal block or a non-metal block. The limit block 21 can be in the shape of a cylinder, a prism, etc. The limit block 21 can be fixed on the pull wire 20 in a variety of ways. For example, the limit block 21 can be integrally formed with the pull wire 20 during production, the limit block 21 can be fixed on the pull wire 20 by casting during production, and the limit block 21 can also be fixed on the pull wire 20 by welding, bonding, etc. Along the length direction of the pull wire 20, the limit block 21 is spaced apart from the protective tube 10, and the dust cover 30 is sleeved on the pull wire 20. The dust cover 30 may be made of rubber. The dust cover 30 is connected between the protective tube 10 and the limit block 21, and the dust cover 30 is fixedly connected to the limit block 21. The limit block 21 may be arranged inside the dust cover 30, or may be arranged outside the dust cover 30. This application is described by taking the limit block 21 arranged inside the dust cover 30 as an example. The dust cover 30 and the limit block 21 may be fixedly connected by means of snap connection, bonding, etc., and the dust cover 30 and the protective tube 10 may be fixedly connected by means of snap connection, threaded connection, etc. It should be noted that when the pull wire 20 is as Figure 1 When placed, the length direction of the pull line 20 is Figure 1 In the X direction.

[0034] In the embodiment of the present application, the dust cover 30 is fixedly connected to the limit block 21, and the limit block 21 is fixed on the pull wire 20. No relative movement can occur between the dust cover 30 and the pull wire 20. When the pull wire 20 is pulled, the pull wire 20 moves together with the limit block 21, and the dust cover 30 moves together with the pull wire 20 as the limit block 21 moves, thereby solving the problem that the hood lock 1 cannot be unlocked due to the freezing of the pull wire 20, so that the hood lock 1 can be smoothly unlocked when the pull wire 20 is frozen, thereby reducing vehicle use failures and improving customer satisfaction.

[0035] In some embodiments of the present invention, Figure 2 As shown, along the length direction of the pull wire 20 , the first end 31 of the dust cover 30 away from the limiting block 21 is fixedly connected to the protective tube 10 , and the second end 32 of the dust cover 30 away from the protective tube 10 is fixedly connected to the limiting block 21 .

[0036] Along the length direction of the pull wire 20, the first end 31 of the dust cover 30 away from the limit block 21 is fixedly connected to the protective tube 10. The dust cover 30 and the protective tube 10 can be fixedly connected by means of threaded connection, clamping, etc. The second end 32 of the dust cover 30 away from the protective tube 10 is fixedly connected to the limit block 21. The limit block 21 is arranged inside the dust cover 30 and is fixedly connected to the dust cover 30. The dust cover 30 and the limit block 21 can be fixedly connected by means of clamping, bonding, etc. The first end 31 of the dust cover 30 is fixedly connected to the protective tube 10, and the second end 32 is fixedly connected to the limit block 21. The limit block 21 and the protective tube 10 are spaced apart in the length direction of the pull wire 20, so that the limit block 21 can move relative to the protective tube 10, and the pull wire 20 can move in the length direction of the pull wire 20, so as to realize the function of pulling the pull wire 20 to unlock the hood lock 1.

[0037] In some embodiments of the present invention, Figure 3 As shown, the second end 32 is formed with an assembly space 321 , the limiting block 21 is assembled in the assembly space 321 , and the limiting block 21 and the dust cover 30 are interference fit.

[0038] The limit block 21 is arranged inside the dust cover 30 and is fixedly connected to the dust cover 30. The limit block 21 is fixedly connected to the second end 32 of the dust cover 30. The second end 32 of the dust cover 30 forms an assembly space 321. The limit block 21 is assembled in the assembly space 321. The assembly space 321 can be a cavity shaped like the limit block 21, and the limit block 21 and the dust cover 30 have an interference fit. The interference fit refers to that there is no gap between the mutually cooperating limit block 21 and the dust cover 30, and they cannot move relative to each other. The limit block 21 and the dust cover 30 have an interference fit, so that there will be no relative movement between the limit block 21 and the dust cover 30, so that there will be no relative movement between the dust cover 30 and the pull wire 20, which solves the problem that the hood lock 1 cannot be unlocked due to the icing of the pull wire 20, so that the hood lock 1 can be smoothly unlocked when the pull wire 20 is frozen, thereby reducing vehicle use failures and improving customer satisfaction.

[0039] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, along the length direction of the pull wire 20 , the assembly space 321 has a first limiting wall 3211 and a second limiting wall 3212 that are opposite and spaced apart, and the first limiting wall 3211 and the second limiting wall 3212 are both in contact with the limiting block 21 .

[0040] The assembly space 321 has a first limiting wall 3211 and a second limiting wall 3212. Along the length direction of the pull wire 20, the first limiting wall 3211 and the second limiting wall 3212 are opposite to each other and spaced apart from each other. One of the first limiting wall 3211 and the second limiting wall 3212 is located on the side of the assembly space 321 facing the protective tube 10, and the other is located on the side of the assembly space 321 away from the protective tube 10. The first limiting wall 3211 and the second limiting wall 3212 are respectively located on both sides of the limiting block 21. The positioning walls 3212 are all in contact with the limit block 21, which limits the limit block 21, so that the limit block 21 will not move relative to each other in the assembly space 321, and the limit block 21 is tightly connected with the dust cover 30, so that the pull wire 20 and the dust cover 30 will not move relative to each other, thereby achieving complete sealing between the dust cover 30 and the pull wire 20, solving the problem that the hood lock 1 cannot be unlocked due to the freezing of the pull wire 20, so that the hood lock 1 can be smoothly unlocked when the pull wire 20 is frozen, thereby reducing vehicle use failures and improving customer satisfaction.

[0041] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the first limiting wall 3211 is located in the dust cover 30 and between the second limiting wall 3212 and the protective tube 10. The first limiting wall 3211 is formed with a first assembly hole 40 connected to the assembly space 321. The limiting block 21 is assembled in the assembly space 321 through the first assembly hole 40, and the pull wire 20 is passed through the first assembly hole 40.

[0042] The second end 32 of the dust cover 30 is formed with an assembly space 321, and the assembly space 321 has a first limiting wall 3211 and a second limiting wall 3212. The first limiting wall 3211 is located in the dust cover 30. Along the length direction of the pull wire 20, the first limiting wall 3211 and the second limiting wall 3212 are opposite to each other and spaced apart from each other. The first limiting wall 3211 is located on the side of the assembly space 321 facing the protective tube 10, and the second limiting wall 3212 is located on the side of the assembly space 321 away from the protective tube 10. The first limiting wall 3211 is located between the second limiting wall 3212 and the protective tube 10, the first limiting wall 3211 is formed with a first assembly hole 40 connected to the assembly space 321, the limiting block 21 is assembled in the assembly space 321 through the first assembly hole 40, the first limiting wall 3211 has a limiting effect on the limiting block 21, the cross-sectional size of the first assembly hole 40 is smaller than the cross-sectional size of the assembly space 321, so that the limiting block 21 can be assembled in the assembly space 321 through the first assembly hole 40, but the limiting block 21 will not easily fall out of the assembly space 321 through the first assembly hole 40, thereby achieving a close fit between the limiting block 21 and the assembly space 321. The first limiting wall 3211 is arranged inside the dust cover 30, and the limiting block 21 is fixed to the pull wire 20. During the assembly process, the limiting block 21 is assembled in the assembly space 321 through the first assembly hole 40, so the pull wire 20 is passed through the first assembly hole 40, and the pull wire 20 is passed through the dust cover 30, so that the pull wire 20 and the dust cover 30 are completely sealed, preventing water vapor from penetrating into the dust cover 30 and freezing, which affects the pulling of the pull wire 20 to unlock the hood lock 1, thereby reducing vehicle failures.

[0043] In some embodiments of the present invention, Figure 3 As shown, the first assembly hole 40 may include a first hole segment 41 and a second hole segment 42, the second hole segment 42 is located between the first hole segment 41 and the assembly space 321, the second hole segment 42 connects the first hole segment 41 and the assembly space 321, and the inner peripheral wall of the first hole segment 41 is configured as a guide slope 411, and the guide slope 411 cooperates with the limit block 21 to guide the limit block 21 so that the limit block 21 is assembled in the assembly space 321.

[0044] The first assembly hole 40 may include a first hole section 41 and a second hole section 42. The first hole section 41 is located at one end of the first assembly hole 40 away from the assembly space 321, and the second hole section 42 is located at one end of the first assembly hole 40 facing the assembly space 321. The second hole section 42 is located between the first hole section 41 and the assembly space 321. The cross-sectional size of the first assembly hole 40 is smaller than the cross-sectional size of the assembly space 321. The second hole section 42 connects the first hole section 41 and the assembly space 321. The inner peripheral wall of the first hole section 41 is constructed as a guiding bevel 411. When the limit block 21 is assembled into the assembly space 321, the guiding bevel 411 guides the limit block 21. The guiding bevel 411 cooperates with the guide of the limit block 21 to facilitate the assembly of the limit block 21 in the assembly space 321, so that the installation of the limit block 21 is easier, the limit block 21 is installed in place, the installation quality is improved, and the dust cover 30 and the pull wire 20 are ensured to be completely sealed.

[0045] In some embodiments of the present invention, Figure 3 As shown, along the length direction of the pull wire 20 , from the end of the first hole segment 41 close to the second hole segment 42 to the end far away from the second hole segment 42 , the cross-sectional area of ​​the first hole segment 41 gradually increases.

[0046] The inner peripheral wall of the first hole section 41 is constructed as a guiding slope 411. Along the length direction of the pull wire 20, from the end of the first hole section 41 close to the second hole section 42 to the end away from the second hole section 42, the cross-sectional area of ​​the first hole section 41 gradually increases. The cross-sectional dimension of the end of the first hole section 41 away from the second hole section 42 is larger than the cross-sectional dimension of the end of the first hole section 41 close to the second hole section 42. The cross-sectional dimension of the first hole section 41 is smaller than the cross-sectional dimension of the assembly space 321. When the limit block 21 is installed, the limit block 21 enters the second hole section 42 through the guiding effect of the guiding slope 411 of the first hole section 41. A hole section 41, the cross-sectional size of the limit block 21 is larger than the cross-sectional size of the first hole section 41, the dust cover 30 undergoes elastic deformation to allow the limit block 21 to pass through the first hole section 41 and the second hole section 42 and enter the assembly space 321, and the dust cover 30 recovers its deformation after being installed in place, so that the installation of the limit block 21 is completed, and a fixed connection between the limit block 21 and the dust cover 30 is achieved. There is no relative movement between the dust cover 30 and the pull wire 20, and a complete seal between the pull wire 20 and the dust cover 30 is achieved, preventing water vapor from penetrating into the dust cover 30 and freezing, which affects the pulling of the pull wire 20 to unlock the hood lock 1, thereby reducing vehicle failures.

[0047] In some embodiments of the present invention, Figure 3 As shown, the second limiting wall 3212 is formed with a second assembly hole 50 communicating with the assembly space 321 , and the pull wire 20 is passed through the second assembly hole 50 .

[0048] The second end 32 of the dust cover 30 is formed with an assembly space 321, and the assembly space 321 has a second limiting wall 3212. The second limiting wall 3212 is formed with a second assembly hole 50 connected to the assembly space 321. Along the length direction of the pull wire 20, the pull wire 20 is inserted into the first assembly hole 40, the pull wire 20 is inserted into the assembly space 321, and the pull wire 20 is inserted into the second assembly hole 50, so that the pull wire 20 is inserted into the dust cover 30. The limiting block 21 is fixed to the pull wire 20. The limit block 21 is fixedly connected to the dust cover 30, so that when the pull wire 20 is pulled, the dust cover 30 can move together with the pull wire 20 along the length direction of the pull wire 20, so that there is no relative movement between the pull wire 20 and the dust cover 30, and a complete seal between the dust cover 30 and the pull wire 20 is achieved, which solves the problem that the hood lock 1 cannot be unlocked due to the icing of the pull wire 20, so that the hood lock 1 can be smoothly unlocked when the pull wire 20 is frozen, thereby reducing vehicle use failures and improving customer satisfaction.

[0049] In some embodiments of the present invention, Figure 2 As shown, a telescopic section 33 is formed in the middle of the dust cover 30 along the length direction of the pull wire 20 .

[0050] Along the length direction of the pull wire 20, a telescopic section 33 is formed in the middle part of the dust cover 30, and the telescopic section 33 is located between the first end 31 and the second end 32 of the dust cover 30.

There is no relative movement between the dust cover 30 and the pull wire 20. The dust cover 30 can be made of rubber. When the pull wire 20 moves, the telescopic section 33 on the dust cover 30 expands and contracts with the movement of the pull wire 20. When the dust cover 30 is pulled with the pull wire 20, the telescopic section 33 expands or folds. When the pull wire 20 is released, the telescopic section 33 returns to its original state, thereby realizing the movement effect of the pull wire 20.
