[0002] The automobile lock system is basically equipped with a pull wire, which transmits the action of the handle to the lock body, so as to realize the opening or locking of the lock system. The pull wire is used to connect the lock body and the handle. The structural part is a die-cast alloy head. The existing die-cast alloy heads for pull wires generally have several structural forms such as spherical, cylindrical, 7-shaped, and Z-shaped. Among them, the Z-shaped die-cast alloy head is more commonly used in automobile lock systems because it is easy to assemble and is not easy to fall off after assembly. It has high reliability.

[0003] To ensure the strength of the wire, the outer diameter of the existing wire rope is generally 1.2~1.5mm, and the outer diameter of the matching Z-shaped die-cast alloy head is generally 3.5~4mm. When the outer diameter of the die-cast alloy head is 3.5±0.1mm, the outer diameter of the wire rope is 1.5±0.1mm, and the outer diameter of the embossed end is 2.7±0.2mm, under the limit state, the single-side material thickness of the die-cast alloy head is only 0.2mm, the reliability tolerance is small, and there is a reliability risk. Summary of the invention

[0005] In order to achieve the above-mentioned purpose, the utility model adopts an automobile cable, comprising:

[0006] A first die-cast alloy head, which is a Z-shaped head with a variable cross-section, wherein the front end of the first die-cast alloy head cooperates with the lock body, and the rear end is connected to the wire rope, and the front end cross-sectional dimension of the first die-cast alloy head is smaller than the rear end cross-sectional dimension;

[0007] A steel wire rope, the front end of which is provided with an embossed end portion, the embossed end portion is connected to the rear end of the first die-cast alloy head, the rear end of the steel wire rope is sheathed with a fixing sleeve and a sleeve, and two fixing sleeves are connected to both ends of the sleeve;

[0008] The second die-cast alloy head is mounted on the handle and connected to the rear end of the steel wire rope for linking the movement of the handle to the pull line.

[0009] In some embodiments, the front end outer diameter a of the first die-casting alloy head is 3.5 mm, and the rear end outer diameter b is 5.5 mm.

[0010] In some embodiments, the outer diameter c of the embossed end is 2.9 mm.

[0021] In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present application are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application.

[0022] In the description of the present invention, it should be understood that the terms "front", "rear", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the protection content of the present invention.

[0023] like Figure 1 , Figure 2 As shown, an automobile cable includes a first die-casting alloy head 1, a steel wire rope 2, a fixing sleeve 3, a sleeve 4 and a second die-casting alloy head 5;

[0024] The first die-cast alloy head 1 is a Z-shaped die-cast alloy head with a variable cross-section. The front end of the first die-cast alloy head 1 cooperates with the lock body, and the rear end is connected to the wire rope 2. The front end cross-sectional size of the first die-cast alloy head 1 is smaller than the rear end cross-sectional size.

[0025] The front end of the steel wire rope 2 is provided with an embossed end 21, and the embossed end 21 is connected to the rear end of the first die-cast alloy head 1. The rear end of the steel wire rope 2 is sheathed with a fixing sleeve 3 and a sleeve 4, and two fixing sleeves 3 are connected to both ends of the sleeve 4;

[0026] The second die-cast alloy head 5 is installed on the handle as a fixed structure for wire drawing. The second die-cast alloy head 5 is connected to the rear end of the wire rope 2, thereby linking the movement of the handle to the wire drawing.

[0027] In some embodiments, Figure 2 As shown, the first die-cast alloy head 1 is connected to the steel wire rope 2 through a die-casting process, and the outer diameter a of the front end installation position matching the lock body is 3.5 mm, thereby meeting the assembly requirements, and the outer diameter b of the rear end position connected to the embossed end 21 of the steel wire rope 2 is 5.5 mm, thereby meeting the reliability requirements.

[0028] In some embodiments, Figure 2 As shown, the outer diameter c of the embossed end 21 is 2.9 mm, the outer diameter b at the rear end of the first die-cast alloy head 1 is 5.5 mm, and the single-side wall thickness is 1.3 mm. Compared with the traditional die-cast alloy head with the same overall cross-section (the overall outer diameter is 3.5 mm, and the single-side wall thickness is only 0.3 mm), the first die-cast alloy head 1 with a variable cross-section of the utility model has a larger reliability tolerance for wire drawing, thereby increasing reliability.

[0029] In some embodiments, Figure 2 As shown, the outer diameter of the embossed end 21 is 2.9 mm, which is larger than the outer diameter of the steel wire rope 2 of 1.5 mm. After the embossed end 21 is connected to the first die-casting alloy head 1 through the die-casting process, the steel wire rope 2 can be prevented from falling off from the first die-casting alloy head 1 under external force.

[0030] In some embodiments, the fixed sleeve 3 and the sleeve 4 are connected by plastic coating or riveting process. The fixed sleeve 3 serves as a fixing structure for the wire drawing. A groove is opened on the fixed sleeve 3, which can be snapped onto the lock body to fix the wire drawing on the lock body and the handle, thereby linking the movement of the handle to the lock body; the sleeve 4 serves as a fixing and protective structure for the wire rope 2, so that when the wire rope 2 is working, it moves according to the design requirements, that is, the direction of the sleeve 4, and fixes the movement trajectory of the wire rope 2, while avoiding abnormal wear.

[0031] The second aspect of the utility model provides an automobile lock system, comprising a lock body and a handle, and also comprising the automobile pull wire, wherein the automobile pull wire is installed between the lock body and the handle.

[0032] A third aspect of the utility model provides a vehicle, on which the automobile lock system is installed.

[0033] When in use, the position where the front end of the variable-section, Z-shaped first die-cast alloy head 1 cooperates with the lock body is designed to match the boundary size of the lock body, thereby realizing the borrowing or continued use of the lock body assembly and reducing development costs. Figure 2 As shown, the outer diameter a of the front end installation position of the first die-cast alloy head 1 is 3.5 mm, and the position where the rear end is connected to the wire rope 2 is designed to have an outer diameter b of 5.5 mm according to the size of the wire rope 2 and the embossed end 21, thereby meeting the reliability requirements of the wire pulling.

[0034] The automobile pull wire of the utility model adjusts the first die-cast alloy head from the overall same cross-section to a variable cross-section (the cross-section of the end that cooperates with the lock body is small, and the cross-section of the end that is connected to the wire rope is large). While satisfying product interchangeability, the installation size of the pull wire remains unchanged, thereby improving the overall reliability of the pull wire.

[0035] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
