Cable mechanism for a car door

Abstract

This utility model relates to the field of cable mechanisms, particularly cable mechanisms for automotive floor gates. The cable mechanism includes a cable and a tension spring. The tail end of the cable is connected to a guide member, which is fixed inside a protective sleeve. One end of the guide member is connected to one end of the tension spring, and the other end of the tension spring is connected to a base. The base is fixed to the tail end of an outer sleeve. The tension spring is placed inside the outer sleeve. Several reinforcing ribs are distributed on the outer wall of the protective sleeve, and these ribs are attached to the inner wall of the outer sleeve. In this utility model, the cable pulls the tension spring through the guide member and the protective sleeve, while the protective sleeve moves linearly within the outer sleeve. This ensures that the tension spring does not touch the outer sleeve when it is extended or retracted. The reinforcing ribs are in direct contact with the outer sleeve, thus reducing the friction surface and consequently reducing wear and noise.

Description

Technical Field

[0001] This utility model relates to the field of cable mechanisms, and in particular to cable mechanisms used in automotive floor gates. Background Technology

[0002] With the continuous development of the automotive industry, multi-door tailgates are increasingly being used by OEMs. A "multi-door" tailgate is a tailgate that is divided into two parts: the upper part opens upwards, and the lower part opens downwards; these two parts are called the "top door" and the "bottom door," respectively. A cable mechanism connects the bottom door to the vehicle's interior, allowing the bottom door to open and close.

[0003] Most of the ground door pull cables on the market currently use a compression spring structure. During the opening of the ground door, the outer diameter of the compression spring will increase with the increase of compression, which will increase the friction between the spring and the inner wall of the sleeve, causing abnormal noise and affecting the service life of the spring. In addition, in order to reduce friction, the compression spring will use a flocking process, which undoubtedly increases the manufacturing cost of the spring. Utility Model Content

[0004] In order to overcome the shortcomings of existing cables with high friction and the outer tube easily rubbing against the tension spring, this utility model provides a cable mechanism for automobile door.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a cable mechanism for a car door, including a cable and a tension spring. The tail end of the cable is connected to a guide member, which is fixed inside a protective sleeve. One end of the guide member is connected to one end of the tension spring, and the other end of the tension spring is connected to a base. The base is fixed to the tail end of the outer sleeve. The tension spring is placed inside the outer sleeve. Several reinforcing ribs are distributed on the outer wall of the protective sleeve, and the reinforcing ribs are attached to the inner wall of the outer sleeve.

[0006] According to another embodiment of the present invention, the outer tube is further provided with a bracket fixed at the top end. The bracket is a disc and has a guide hole for the cable to pass through.

[0007] According to another embodiment of the present invention, the cable is further provided with a metal ball socket at the top end.

[0008] According to another embodiment of the present invention, the protective sleeve is further comprising a circular sleeve, with several reinforcing ribs distributed on the outer circumference of the circular sleeve, and the guide member passing through the circular sleeve.

[0009] According to another embodiment of the present invention, the guide member is further provided with a through hole at one end, and the hook at one end of the tension spring passes through the through hole in the guide member.

[0010] According to another embodiment of the present invention, the guide member is further provided with a threaded groove at one end, and the tension spring is fixed in the threaded groove at one end.

[0011] According to another embodiment of the present invention, the protective sleeve and reinforcing ribs are further made of plastic.

[0012] The beneficial effects of this utility model are that the cable pulls the tension spring through the guide and the protective sleeve, while the protective sleeve moves linearly inside the outer tube. This ensures that the tension spring will not touch the outer tube when it is stretched or retracted. The reinforcing rib is in direct contact with the outer tube, so that the protective sleeve contacts the outer tube line when it moves, which greatly reduces the friction surface and thus reduces wear and noise.

[0015] Figure 1 This is a structural schematic diagram of the present invention. Figure 2 This is a schematic diagram of the structure of the protective cover of this utility model.

[0016] A cable mechanism for a car door includes a cable 1 and a tension spring 2. The tail end of the cable 1 is connected to a guide 3, which is fixed inside a protective sleeve 4. One end of the guide 3 is connected to one end of the tension spring 2, and the other end of the tension spring 2 is connected to a base 5. The base 5 is fixed to the tail end of an outer sleeve 6. The tension spring 2 is placed inside the outer sleeve 6. Several reinforcing ribs 9 are distributed on the outer wall of the protective sleeve 4 and are attached to the inner wall of the outer sleeve 6.

[0017] The top of the outer tube 6 is fixed with a bracket 7, which is a disc and has a guide hole for the cable 1 to pass through.

[0018] The top of cable 1 is provided with a metal ball socket 8.

[0019] The metal ball socket 8 contains a metal ball for movable connection to the carriage door.

[0020] The protective sleeve 4 is a circular sleeve with several reinforcing ribs 9 distributed on the outer circumference of the sleeve, and the guide 3 passes through the circular sleeve.

[0021] One end of the guide member 3 has a through hole, and the hook at one end of the tension spring 2 passes through the through hole in the guide member 3.

[0022] One end of the guide member 3 is provided with a threaded groove, and one end of the tension spring 2 is fixed in the threaded groove.

[0023] The protective sleeve 4 and the reinforcing rib 9 are made of plastic. When the plastic reinforcing rib 9 rubs against the outer sleeve 6, it can further reduce noise.

[0024] As the cable 1 moves back and forth within the inner cavity of the outer tube 6, the protective sleeve 4, with reinforcing ribs 9, connected to the tail end of the cable 1, moves linearly along the inner cavity of the outer tube 6. Since the reinforcing ribs 9 of the protective sleeve 4 are in direct contact with the inner wall of the outer tube 6, the contact area is greatly reduced, thereby reducing friction and noise. Furthermore, the linear movement of the guide member 3 and the protective sleeve 4 within the outer tube 6 prevents the tension spring 2 from shifting position when it pulls it, ensuring that the tension spring 2 never contacts the outer tube 6 during stretching or retraction.
