Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a side groove roller type vehicle door stopper device. Background Art
[0002] Door checkers limit the extent to which a door can open, while also keeping it open at certain angles. They prevent the door from opening too far, limiting its maximum opening. They also help keep the door open when the car is parked on a slope or in generally windy conditions. Common door checkers are separate pull-strap type checkers, while others are integrated into the door hinges. These checkers typically function as a stopper when the door is fully or partially opened.
[0003] The traditional limiter often has a groove slope along the axial direction of the limit arm, pushing the slider in the limit shell and then squeezing the rubber spring in, pushing the door closed under the reaction force. This method is prone to the problem that the operating force needs to be increased in the later stage of the door closing action, and the door closing quality is reduced. In order to improve the above problems, some traditional limit arms with limit grooves set along the side of the limit arm have emerged. However, the use of ordinary sliders is prone to abnormal noise after a long period of use, and the limiter gear torque fluctuation is prone to large fluctuations during mass production. Utility Model Content
[0004] The purpose of the present utility model is to provide a side groove roller type vehicle door limiter device to solve the problem proposed in the above background technology that the existing limiter is prone to the problem that the operating force needs to be increased in the later stage of the door closing action, resulting in a decrease in the door closing quality, and the use of ordinary sliders is prone to abnormal noise after a long period of use, and the problem that the limiter gear torque fluctuates greatly during mass production.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a side groove roller type vehicle door stopper device, comprising a bracket, the bracket being fixed to the vehicle body, a pin and a stop arm being provided on one side of the bracket, the bracket and the stop arm being connected for axial movement via the pin;
[0006] Also includes:
[0007] The roller-type integral motion structure is arranged at the middle position of the limit arm, and the roller-type integral motion structure consists of the front half of the door fixing block, the rear half of the door fixing block, a special-shaped spring, a roller, a roller cover, a U-shaped gasket, an adjusting bolt, and a limit sleeve.
[0008] Preferably, the adjusting bolt is mounted on the roller housing, and the limiting sleeve is mounted on the threaded end of the adjusting bolt.
[0009] Preferably, the roller is snap-fitted to the roller housing, and a U-shaped hole groove is built into the interior of the roller housing.
[0010] Preferably, two ends of the two special-shaped springs are respectively fixed to the upper end and the lower end of the two roller housings.
[0011] Preferably, the front half of the vehicle door fixing block is buckled with the rear half of the vehicle door fixing block.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. The rollers and elastic device of the utility model are arranged on both sides of the limiter arm. When the car door performs the closing action, the direction of the force of the elastic device and the direction of the closing rotation are a planar transmission route, which can improve the force transmission effectiveness of the limiter to perform the closing action, reduce the closing speed and shift force, and improve the closing quality.
[0014] 2. The utility model replaces the traditional slider with a roller structure, which can effectively reduce abnormal noise.
[0015] 3. The position of the utility model relative to the cover is adjustable, which can effectively reduce the output of unqualified products with shifting force during mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] See also Figure 1-4The present invention provides an embodiment of a side groove roller door stopper device, comprising a bracket 1, the bracket 1 being fixed to the vehicle body, a pin 2 and a stop arm 3 being provided on one side of the bracket 1, the bracket 1 and the stop arm 3 being connected to each other through the pin 2 for axial movement;
[0023] Also includes:
[0024] The roller-type integral motion structure 4 is arranged in the middle position of the limit arm 3, and the roller-type integral motion structure 4 consists of the front half 41 of the door fixing block, the rear half 42 of the door fixing block, the special-shaped spring 43, the roller 44, the roller cover 45, the U-shaped gasket 46, the adjusting bolt 47, and the limit sleeve 48.
[0025] During use, the adjusting bolt 47 is first installed in the corresponding position of the roller housing 45, and the limiting sleeve 48 is then installed on the threaded end. Finally, the roller 44 is inserted into the roller housing 45. The roller housing 45 has a U-shaped hole groove to provide a certain depth adjustment. By adjusting the screwing depth of the bolt 47, the position of the limiting sleeve 48 installed on the threaded end is controlled, and thus the position of the roller 44 relative to the roller housing 45 in the assembled state is controlled. During adjustment, the U-shaped gasket 46 can be used with the nut end to determine the final position of the adjusting bolt 47. Finally, the two ends of the special-shaped spring 43 are respectively fixed to the upper and lower ends of the two roller housings 45. The elastic force of the spring toward the limiting arm is used to make the roller 44 close to the limiting arm 3. Finally, the front half 41 of the door fixing block is fastened to the rear half 42 of the door fixing block and bolted together. The fastening also fixes the U-shaped end of the special-shaped spring 43 into a whole.
[0026] See also Figure 4 The adjusting bolt 47 is installed on the roller housing 45 , and the limiting sleeve 48 is installed on the threaded end of the adjusting bolt 47 .
[0027] See also Figure 4 The roller 44 is snap-fitted to the roller housing 45 , and a U-shaped hole groove is built into the interior of the roller housing 45 .
[0028] See also Figure 4 The two ends of the two special-shaped springs 43 are respectively fixed to the upper and lower ends of the two roller housings 45.
[0029] See also Figure 4 , the front half 41 of the door fixing block is buckled with the rear half 42 of the door fixing block.
[0030] Working principle: The entire limiting arm is first assembled with the roller-type integral motion structure 4. At this time, the roller covers 45 on both sides are tightened inward due to the spring force of the special-shaped springs 43. Use a tool to use a certain force to expand the roller covers 45 on both sides outward, and insert the limiting arm 3 along the square hole in the middle of the front half 41 of the car door fixing block. Release the tool. At this time, the roller 44 will clamp the limiting arm 3 through the spring force. Finally, install the bracket 1 and rivet the pin 2. When the shift force fluctuates greatly, you can adjust the depth of the adjusting bolt 47 on the roller-type integral motion structure 4, and add an appropriate number of U-shaped gaskets 46 to the nut end to control the position of the roller 44 relative to the roller cover 45 in the assembled state to adjust the shift force and finally complete the product output.
[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
