[0001] The utility model relates to the technical field of automotive parts, in particular to a hinge with a multi-stage opening degree adjustment function. Background Art
[0002] An automotive door hinge is an important part of automotive parts. The automotive door hinge can connect the car door and the vehicle body to realize the normal opening and closing of the car door. However, most of the automotive door hinges on the market do not have the function of multi-stage adjustment of the door opening degree, and cannot effectively meet the use requirements of door opening degrees for people of different body types and in different environmental states; while a few automotive door hinges have the function of multi-stage adjustment of the door opening degree, but on the one hand, the upper limit position structure of the required door opening degree of such automotive door hinges is complex and the assembly difficulty is high, and on the other hand, due to the door opening and closing actions, air oxidation, etc., it is easy to cause wear and damage to the rotating part of the hinge, resulting in problems such as abnormal noise and jamming during the opening and closing of the door, and the door cannot be opened and closed smoothly, and the stability during long-term use cannot be guaranteed. Summary of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a hinge with a multi-stage opening degree adjustment function. The multi-stage adjustment function of the door opening degree is realized by setting a positioning slider and a plurality of limit grooves in cooperation, which is simple in structure and easy to install, and effectively meets the use requirements of users; and it can effectively reduce the wear rate of the rotating part of the hinge, so that the door can still maintain a smooth opening and closing action under long-term use.
[0004] In order to achieve the above purpose, a hinge with a multi-stage opening degree adjustment function provided by the utility model includes a fixed seat and a movable seat, and the fixed seat and the movable seat are rotationally connected through a rotating shaft. At least one guiding chute is formed on the fixed seat and arranged around the rotating shaft for the slidable connection of a preset retractable positioning slider on the movable seat. As the movable seat rotates, the positioning slider slides along the guiding chute, so that the opening degree between the fixed seat and the movable seat gradually increases or decreases; a number of limit grooves are also formed in the guiding chute and are fitted with the positioning slider in an embedded manner. When the positioning slider slides to one of the limit grooves, it is engaged and limited with the limit groove, and the positioning slider retracts inward when continuing to slide along the guiding chute to avoid and withdraw from the limit groove.
[0005] Further, a guiding portion extending around the rotating shaft is formed on the fixed seat, and two of the guiding chutes are respectively formed at the end faces at both ends of the guiding portion.
[0006] Further, a through groove for the guiding portion to penetrate is formed on the movable seat.
[0007] Further, a sliding cavity extending vertically and having one end extending through to the outside of the movable seat is formed in the movable seat. Among them, a sliding ball that can slide along the inner wall thereof is provided in the sliding cavity, and a part of the sliding ball can extend out of the sliding cavity. At this time, the part of the sliding ball extending out of the sliding cavity serves as a positioning slider.
[0008] Further, a compression spring is further provided between the sliding cavity and the sliding ball. Among them, one end of the compression spring is in abutting and cooperating with the sliding ball.
[0009] Further, it further includes two limiting collar sleeves coaxially sleeved on the rotating shaft. Among them, the fixed seat and the movable seat respectively touch and stop against the upper end surface and the lower end surface of the limiting collar sleeve.
[0010] Further, a plurality of mounting holes for a preset screw to pass through and connect are formed in both the fixed seat and the movable seat.
[0011] Adopting the above solution, the beneficial effect of the present utility model is that the multi - gear adjustment function of the door opening degree is realized by the cooperation of the positioning slider and multiple limiting grooves; the rotation friction generated when the door is opened or closed is effectively reduced by setting the sliding ball, avoiding abnormal noise and jamming of the door during long - term use, and maintaining a smooth opening and closing action.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the accompanying drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.
[0020] The implementation details of the technical solutions of the embodiments of the present utility model are elaborated in detail below: For the convenience of those skilled in the art to understand, the Figure 5 accompanying drawings adopt partial perspective views for illustration, and the Figure 5 dotted line in the accompanying drawings shows the perspective part of the housing of the movable seat 2.
[0021] Referring to the Figure 1 to the Figure 4 accompanying drawings, a hinge with a multi-stage opening degree adjustment function in this embodiment includes a fixed seat 1 and a movable seat 2 respectively fixedly connected to the vehicle body and the vehicle door, and the fixed seat 1 and the movable seat 2 are rotatably connected by a rotating shaft 3. Among them, a positioning slider 21 is preset on the movable seat 2, and at least one guiding chute 111 arranged around the rotating shaft 3 and for the positioning slider 21 to slide and connect is formed on the fixed seat 1, and a number of limiting grooves 112 fitted with the positioning slider 21 are formed in the guiding chute 111. Specifically, when the vehicle door is opened or closed, the movable seat 2 is driven to rotate around the rotating shaft 3. At this time, the positioning slider 21 slides along the guiding chute 111. And when the positioning slider 21 slides outward along the guiding chute 111 (i.e., when the vehicle door is opened), the relative angle between the fixed seat 1 and the movable seat 2 increases, that is, the opening degree between the fixed seat 1 and the movable seat 2 gradually increases; when the positioning slider 21 slides inward along the guiding chute 111 (i.e., when the vehicle door is closed), the relative angle between the fixed seat 1 and the movable seat 2 decreases, that is, the opening degree between the fixed seat 1 and the movable seat 2 gradually decreases.
[0022] More specifically, when the positioning slider 21 slides along the guide slide groove 111 to one of the limiting grooves 112, the positioning slider 21 is embedded in the limiting groove 112 and contacts the inner wall of the limiting groove 112 to achieve the embedded limit, the rotation of the movable seat 2 is restricted, and the opening or closing action of the car door is stagnant; at this time, if the car door is pushed to continue to open or close, the positioning slider 21 will contact the inner wall of the limiting groove 112 and retract inward under the action of the impact force generated by the contact, thereby avoiding and exiting the limiting groove 112 to release the rotation restriction of the movable seat 2, and the positioning slider 21 slides along the guide slide groove 111 again, and the car door can be further opened or closed; then, when the positioning slider 21 slides along the guide slide groove 111 to the next limiting groove 112, it will be embedded and limited again. In addition, when the positioning slider 21 slides to the front / end of the guide slot 111, the positioning slider 21 contacts and is restricted by the end wall of the guide slot 111 and cannot escape. At this time, the movable seat 2 cannot continue to rotate, and the door is closed or reaches the limit opening. Therefore, by setting the positioning slider 21 and the plurality of limiting grooves 112 to cooperate with each other, the multi-gear adjustment function of the door opening is realized, and there is a certain gear sense when the door rotates, which meets the user's use needs and improves the user's use experience; and the structure is simple and easy to install, saving time and effort.
[0023] See attached Figure 5 and attached Figure 6 As shown, in this embodiment, the side portion of the fixed seat 1 is fixedly sleeved on the rotating shaft 3, and the side portion of the movable seat 2 is coaxially sleeved on the rotating shaft 3, so that the movable seat 2 can rotate around the rotating shaft 3 and rotate relative to the fixed seat 1. Further, two limiting collars 6 are coaxially sleeved on the rotating shaft 3, wherein the two limiting collars 6 cooperate to clamp and fix the movable seat 2, and the fixed seat 1 and the movable seat 2 respectively contact the upper end surface and the lower end surface of the limiting collar 6 to stop, thereby playing the role of fixing and limiting the fixed seat 1 and the movable seat 2. Furthermore, a plurality of mounting holes 7 for preset screws to penetrate and connect are opened on both the fixed seat 1 and the movable seat 2, so as to strengthen the connection between the fixed seat 1 and the car body, and the movable seat 2 and the car door.
[0024] Continue to refer to the attached Figure 5 and attached Figure 6As shown, in this embodiment, a convex block (i.e., the guiding portion 11) is formed on the side position of the fixed seat 1, one end of which is integrally connected (or separately connected) to the fixed seat 1, and the other end is suspended and protrudes from the fixed seat 1 and extends around the rotating shaft 3. Guiding chutes 111 are respectively formed at the end faces of both ends of the guiding portion 11; and a through slot 22 is correspondingly formed in the movable seat 2 for the horizontal penetration of the guiding portion 11, so that the movable seat 2 can freely rotate around the rotating shaft 3. Specifically, a sliding cavity 23 extending vertically is formed in the movable seat 2, and one end of the sliding cavity 23 extends through the periphery of the movable seat 2 and communicates with the through slot 22. A sliding ball 4 that can slide along the inner wall thereof is provided in the sliding cavity 23, and a part of the sliding ball 4 protrudes from the sliding cavity 23 and abuts against the guiding chute 111. At this time, the part of the sliding ball 4 protruding from the sliding cavity 23 serves as the positioning slider 21. It should be noted that the number of settings, the opening positions, the opening specifications, and the spacing of the guiding portion 11, the guiding chutes 111, and the limiting grooves 112 are all set according to actual production requirements and are not limited here.
[0025] Furthermore, a compression spring 5 is further provided between the sliding cavity 23 and the sliding ball 4 to enable a part of the sliding ball 4 to remain protruding from the sliding cavity 23 and ensure the abutting effect between the sliding ball 4 and the guiding chute 111. Specifically, one end of the compression spring 5 is in abutting and pressing cooperation with the sliding ball 4, and the other end is connected to the port of the sliding cavity 23; when the sliding ball 4 is touched by the guiding portion 11, it retracts into the sliding cavity 23 and presses against the compression spring 5, and when the sliding ball 4 slides to the limiting groove 112, the touching force of the guiding portion 11 decreases, and the sliding ball 4 is driven by the elastic force of the compression spring 5 to partially (i.e., the positioning slider 21) protrude from the sliding cavity 23 and cooperate with the limiting groove 112 for limiting. By providing the sliding ball 4 and the compression spring 5, the frictional resistance generated when the vehicle door is opened or closed can be effectively reduced, the wear rate of components can be reduced, and the occurrence of abnormal noises, jams, etc. can be reduced; it can also reduce the sense of stagnation when the vehicle door rotates, make the vehicle door rotate smoothly, and keep the vehicle door opening and closing smoothly during long-term use.
[0026] The above-described embodiments are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, makes more possible changes and refinements or modifications to the technical solution of the present invention using the technical content disclosed above, which are all equivalent embodiments of the present invention.
