Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of door limiters, specifically to a door limiter with quick removal and pressure adjustment functions. Background Technology
[0002] Door limiters are components that restrict the degree to which a car door opens, primarily limiting the maximum opening angle and maintaining that angle. Currently, traditional door limiters have a fixed limiting resistance value. When applied to different car models, due to variations in door weight, the opening and closing feel cannot be adjusted with a fixed limiting resistance, resulting in poor applicability. Furthermore, with prolonged use and wear, the limiting resistance value decreases, currently requiring replacement, which is costly. Additionally, traditional door limiters have a single integrated frame and limit rod, making them impossible to disassemble separately for repair; the door trim panel must be removed, complicating repair procedures. Therefore, a door limiter with quick removal and pressure adjustment capabilities is needed to address these issues. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please see Figure 1-6 The present invention provides the following technical solution:
[0024] A door limiter with quick removal and pressure adjustment functions includes a limit rod 1, a door fixing base 3, and a limiter frame box 4. The door fixing base 3 is a plate-shaped structure with a through hole in the middle. The limiter frame box 4 is detachably installed on the door fixing base 3. For example, the limiter frame box 4 is connected to the door fixing base 3 by fixing bolts 9. The door fixing base 3 is fixed to the inside of the door by welding. The limiter frame box 4 is installed on the outside of the door. The purpose of this setting is that when the limiter frame box 4 needs to be inspected, it can be quickly disassembled and inspected without removing the door trim panel.
[0025] The limiter frame box 4 also has a through hole in the middle. One end of the limiter rod 1 passes through the through hole on the door fixing base 3 and the limiter frame box 4. The end of the limiter rod 1 away from the door fixing base 3 is connected to the body fixing base 11 by a rivet 10.
[0026] The end of the limiting rod 1 located on one side of the door fixing base 3 is provided with a rectangular block, and a buffer pad 2 for buffering is provided on the rectangular block of the limiting rod 1. The purpose of the rectangular block is to cooperate with the door fixing base 3 to prevent the limiting rod 1 from separating from the door fixing base 3, thereby limiting the maximum opening of the door. The buffer pad 2 provides buffering when the rectangular block contacts the door fixing base 3.
[0027] The through hole on the door fixing base 3 is rectangular. The long side of the rectangular block on the limiting rod 1 is larger than the wide side of the rectangular through hole on the door fixing base 3. The purpose of this setting is that when the rectangular block on the limiting rod 1 passes through the rectangular through hole on the door fixing base 3 and rotates, the rectangular block and the rectangular through hole can form a limiting relationship, so that the limiting rod 1 cannot be separated from the door fixing base 3.
[0028] The limiter frame box 4 has a clamping mechanism on both sides that can adjust the pressure on the limit rod 1. The clamping mechanism includes a limit spring 6, a roller 7, and a retainer 8. The retainer 8 is slidably connected to the upper and lower sides inside the limiter frame box 4. The roller 7 for pressing the surface of the limit rod 1 is rotatably connected to the retainer 8. The upper and lower end faces of the limiter frame box 4 are provided with threaded holes. The pressure adjusting bolts 5 are threaded into the threaded holes. The limit spring 6 is provided between the pressure adjusting bolts 5 and the retainer 8. The roller 7 is pressed against the upper and lower side faces of the limit rod 1. The upper and lower side faces of the limit rod 1 are provided with several arc-shaped protrusions. These protrusions are used to cooperate with the clamping mechanism to achieve the limit.
[0029] The internal space of the limiter frame box 4 can also store grease, so that the roller 7 and the cage 8 can be automatically lubricated during the movement, solving the problem that other types of limiters need to apply lubricating medium multiple times, thereby reducing friction and wear and extending the service life of the limiter.
[0030] The working process of this utility model is as follows:
[0031] When installing the door limiter of this invention, first install the limiter frame box 4 onto the door fixing base 3 on the door, insert the limiter rod 1 into the through hole of the limiter frame box 4 and rotate it 90° so that the protrusion on the limiter rod 1 faces the roller 7, and then install the body fixing base 11 onto the vehicle body to complete the installation of the door limiter. When disassembly and maintenance are required, the limiter frame box 4 and the limiter rod 1 can be disassembled separately without removing the door trim panel, making the operation convenient and quick.
[0032] When it is necessary to adjust the limiting resistance of the door limiter, the pressure adjusting bolt 5 is rotated to compress or release the limiting spring 6, which causes the pressure of the roller 7 on the surface of the limiting rod 1 to change. When the roller 7 passes the protruding part of the surface of the limiting rod 1, different limiting resistances can be generated, thereby improving the applicability of the door limiter and making it easier to adjust and maintain after wear.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
