Description

Technical Field

[0001] The utility model relates to the field of vehicle door hinges, in particular to a wear-resistant vehicle door hinge. Background Art

[0002] The basic function of a door hinge is to connect the door and the car body so that the door can rotate naturally and smoothly to open and close. It is responsible for connecting the door and the car body, ensuring the opening and closing of the door, and allowing the driver and passengers to enter and exit the vehicle conveniently. The role of the door hinge in safety is also very important. It needs to be able to withstand a certain amount of tension to ensure that the door will not fall off in the event of an accident such as a collision, thereby ensuring the safety of the passengers.

[0003] After searching, the Chinese patent publication number CN217558029U discloses a wear-resistant car door hinge. The utility model is mainly composed of a spherical connector, a wear-resistant component and other components. The spherical connector is used to connect the female hinge and the male hinge together. The ball sockets and steel balls are arranged in multiple groups on the inner wall of the ball shell. After the ball head is placed in the ball shell, the ball head is in contact with multiple groups of steel balls, which is beneficial to reduce the friction between the ball shell and the ball head, thereby improving the service life of the female hinge and the male hinge.

[0004] However, similar to the above-mentioned wear-resistant door hinge device, the friction between the ball shell and the ball head is reduced by a steel ball. However, due to the small contact area between the steel ball and the ball head, stress concentration will be caused in the device, which will cause damage to the device, affecting the safety and service life of the device. It is difficult to repair after damage. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0022] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 The wear-resistant door hinge of the present invention includes a mounting plate 1 and a mounting plate 2. Both the mounting plate 1 and the mounting plate 2 are provided with mounting holes 3. A sleeve 5 is provided at one end of the mounting plate 2. A connecting shaft 4 is provided between the sleeve 5 and the mounting plate 1. A plurality of rotating cylinders 6 are provided on the inner side of the sleeve 5. A fixing rod 7 is provided on the inner side of the rotating cylinder 6. A fixing piece is provided between the fixing rod 7 and the sleeve 5.

[0024] In this embodiment, when the mounting plate 1 and the mounting plate 2 rotate relative to each other, the mounting plate 2 drives the sleeve 5 to rotate accordingly, and the sleeve 5 drives the rotating drum 6 to move accordingly through the fixed rod 7. At the same time, the rotating drum 6 avoids rotation on the fixed rod 7, thereby achieving the effect of reducing friction during rotation and improving the wear resistance and safety of the device.

[0025] Combine Figure 2 、 Figure 4As shown, the fixing part includes a fixing plate 9, which is plugged into one end of the sleeve 5, and a threaded hole 8 is provided at the other end of the sleeve 5. One end of the fixing rod 7 passes through the fixing plate 9 and is threadedly connected to the threaded hole 8. When the rotating drum 6 is damaged, after separating the mounting plate 1 from the mounting plate 2, the staff drives the fixing rod 7 with a tool so that it cannot rotate, and the fixing rod 7 is removed from the threaded hole 8, thereby releasing the restriction on the fixing plate 9, and then the fixing plate 9 and the rotating drum 6 are taken out and replaced with a new rotating drum 6, and then the fixing plate 9 is installed in the corresponding position in reverse.

[0026] In a preferred embodiment, a positioning block 10 is provided on the fixing plate 9, and a positioning groove 11 is provided on the sleeve 5 at the position corresponding to the positioning block 10. The positioning block 10 is plugged into the positioning groove 11, and one end of the positioning block 10 is chamfered. When installing the fixing plate 9, by plugging the positioning block 10 into the positioning groove 11, the fixing rod 7 and the threaded hole 8 can be easily aligned, thereby improving the convenience during installation.

[0027] Replay Figure 1 As shown, a rubber sleeve 15 is provided on the outside of the sleeve 5, one end of the rubber sleeve 15 is fixedly connected to the mounting plate 1, and the other end of the rubber sleeve 15 is fixedly connected to the mounting plate 2 2. The rubber sleeve 15 protects and shields the connection area between the mounting plate 1 and the mounting plate 2, thereby preventing the entry of dust and moisture from causing wear and erosion of the device.

[0028] like Figure 3 As shown, one end of the mounting plate 2 connected to the sleeve 5 is arranged in a "Z" shape, and a rib 14 is provided at the corner of the mounting plate 2. There are two ribs 14, and the two ribs 14 are symmetrically arranged. One end of the mounting plate 2 is reinforced by the ribs 14, thereby improving the connection stability between the mounting plate 2 and the mounting plate 1, and at the same time improving the safety of the device.

[0029] In a preferred embodiment, a reinforcing plate 13 is provided on the lower end surface of the mounting plate 2, and the reinforcing plate 13 is fixedly connected to the mounting plate 2. The reinforcing plate 13 is provided in the middle of the mounting plate 2, and the reinforcing plate 13 is provided in a "cross" shape. The plane of the mounting plate 2 is reinforced by the reinforcing plate 13, thereby improving the stability of the mounting plate 2 when subjected to force.

[0030] like Figure 2 As shown, the connecting end of the mounting plate 1 and the sleeve 5 is set to be "U"-shaped, and a gasket 12 is set between the two ends of the sleeve 5 and the mounting plate 1. The gasket 12 is sleeved on the connecting shaft 4. The gasket 12 is set as rubber. The gasket 12 prevents the mounting plate 2 2 and the mounting plate 1 from contacting each other to cause unnecessary wear. At the same time, the gasket 12 can play a certain sealing effect.
