[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a car door limiter. By setting the limiter component, it can effectively limit the excessive rotation of the car door when it is subjected to a certain external force. The limiter component not only prevents the car door from rotating without restriction when it is impacted by external force, but also ensures the safety and stability of the vehicle. At the same time, it can also provide necessary limit function when the car door is in a half-closed state, so that the car door will not shake or close suddenly in the half-closed state, further improving the convenience and safety of the car door and ensuring the comfort of passengers during the journey.

[0020] This utility model provides an automotive door limiter. Through the setting of the lubrication component, it can achieve uniform and fine application of lubricating oil to the surface of the limit arm, ensuring that the surface is fully lubricated. The limit arm can maintain a high degree of smoothness when moving, avoiding the problem of excessive surface wear caused by long-term frequent use. This uniform application of lubricating oil effectively prevents the limit arm from jamming or becoming uneven during movement, thereby significantly improving the overall operating performance of the limit arm. This lubrication measure can also significantly extend the service life of the limit arm, allowing it to maintain a good working condition even after long-term use, further enhancing the reliability and durability of the limit arm.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0033] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0034] Example 1: Please refer to Figures 1-7A car door limiter includes: a mounting bracket 1 and a limiting arm 2 rotatably connected to the mounting bracket 1; a limiting box 3 disposed on the limiting arm 2, and the limiting box 3 having a channel a4 through which the limiting arm 2 passes; a limiting component 5 disposed inside the limiting box 3 for segmented limiting of the limiting arm 2; a lubrication mechanism 6 adapted to the limiting arm 2 disposed inside the limiting box 3 for applying lubricating oil to the surface of the limiting arm 2; a rubber buffer block 11 fixed on the limiting arm 2; and a rubber buffer ring 12 adapted to the rubber buffer block 11 fixed on the limiting box 3. The addition of the rubber buffer block 11 and the rubber buffer ring 12 provides a certain buffering effect when the car door is closed, avoiding collision damage when the car door is closed.

[0035] The limiting box 3 is fixed with a mounting base plate 13. The mounting base plate 13 has at least two mounting holes 14 and a channel b15 that is consistent with the channel a4. The addition of the mounting base plate 13 effectively enhances the stability of the mounting limiting box 3. The mounting holes 14 facilitate the installation of the mounting base plate 13 and the limiting box 3 on the car door.

[0036] Furthermore, the limiting component 5 includes: a support frame 51 fixed inside the limiting box 3, a roller a52 rotatably connected to the support frame 51, and the roller a52 contacting the limiting arm 2, a limiting groove 53 being formed on the limiting arm 2, and a limiting protrusion a54 and a limiting protrusion b55 being fixed on the limiting arm 2, a damper 56 being fixed inside the limiting box 3, a bearing bracket 57 being fixed to the other end of the damper 56, and a spring a58 being sleeved on the surface of the damper 56, one end of the spring a58 being fixed to the limiting box 3, and the other end of the spring a58 being fixed to the bearing bracket 57, and at least two rollers b59 being rotatably connected to the bearing bracket 57;

[0037] Among them, the limiting protrusions a54 and b55 are both set with arc surfaces, and the limiting groove 53 is set with an arc surface on the side adjacent to the limiting protrusions a54 and b55. Through the arc slope between the limiting groove 53 and the limiting protrusions a54 and b55, it is ensured that the cam b can move smoothly up and down after being subjected to force when the limiting arm 2 moves, effectively avoiding the situation where the roller b59 gets stuck.

[0038] It should be noted that by setting the limiting component 5, the door can be effectively restricted from excessive rotation when subjected to a certain external force. The limiting component 5 can not only prevent the door from rotating without restriction when subjected to external impact, thus ensuring the safety and stability of the vehicle. At the same time, it can also provide necessary limiting functions when the door is in a half-closed state, so that the door will not shake or close suddenly in the half-closed state, further improving the convenience and safety of the door and ensuring the comfort of passengers during the journey.

[0039] The door is limited by the limiting component 5 as follows: When the door gradually opens, it moves the limiting arm 2 synchronously. When the limiting protrusion a54 and the roller b59 are squeezed, the distance between the roller a52 and the roller b59 increases. With the cooperation of the damper 56 and the spring a58, the roller b59 is always in contact with the limiting arm 2. When the limiting arm 2 continues to move, the first limit is reached when the roller b59 is stuck in the arc surface of the limiting protrusion b55. At this time, the door continues to rotate. When it rotates to a certain position, the second limit is reached when the roller b59 is stuck in the limiting groove on the limiting arm 2. At the same time, the rubber buffer block 11 on the limiting arm 2 collides with the rubber buffer ring 12 on the limiting box 3, thus limiting the door to the maximum opening.

[0040] Example 2: Please refer to Figures 5-7 This embodiment further explains the first embodiment, the difference being the method of adding lubricating oil to the limiting arm 2.

[0041] Furthermore, the lubrication mechanism 6 includes: an oil reservoir 61 slidably connected inside the limiting box 3; a brush roller 62 rotatably connected inside the oil reservoir 61 via a rotating rod a, with the brush roller 62 contacting the limiting arm 2; an installation tube 63 connected to the interior fixed on the oil reservoir 61; a connecting pipe 64 fixed on the limiting box 3, slidably connected inside the installation tube 63; a cover plate 10 slidably connected on the oil reservoir 61, with the connecting pipe 64 located on one side of the cover plate 10; the cover plate 10 serves to block the port of the connecting pipe 64, preventing impurities from entering the oil reservoir 61; at least two mounting plates 65 fixed inside the limiting box 3; a spring sheet 66 fixed between the mounting plates 65 and the oil reservoir 61; and an oil injection component provided on the oil reservoir 61. 7. The oil filling part 7 is used to fill the lubricating oil in the oil reservoir 61 onto the limiting arm 2. The central axis of the connecting pipe 64 and the central axis of the mounting pipe 63 are collinear. The length of the connecting pipe 64 inside the mounting pipe 63 is greater than the length of the slide groove 8. Through the cooperation of the connecting pipe 64 and the mounting pipe 63, it can be ensured that the mounting pipe 63 slides smoothly along the connecting pipe 64, avoiding excessive wear and damage to the mounting pipe 63 and the connecting pipe 64. At least two slide grooves 8 are opened in the oil reservoir 61, and the oil reservoir 61 is slidably connected in the slide grooves 8 by the slider 9. The sliding of the oil reservoir 61 in the slide grooves 8 can play a guiding and limiting role for the oil reservoir 61, ensuring the stability of the oil reservoir 61 when it moves up and down.

[0042] Specifically, the oil filling component 7 includes: a baffle 71 slidably connected inside the oil storage box 61; several permeation holes 72 are opened on the oil storage box 61, and the baffle 71 is located on one side of the permeation holes 72; a through groove 73 is opened on the oil storage box 61; a connecting plate 74 is fixed on the baffle 71 and slidably connected in the through groove 73; a pulley 75 is rotatably connected to the connecting plate 74 through a rotating rod b; the pulley 75 contacts the limiting arm 2; and an mounting plate 76 is fixed on the oil storage box 61; at least two springs b77 are fixed together between the mounting plate 76 and the connecting plate 74.

[0043] It should be noted that the lubrication components enable uniform and meticulous application of lubricating oil to the surface of the limit arm 2, ensuring that the surface is adequately lubricated. This allows the limit arm 2 to maintain a high degree of smoothness during movement, preventing excessive surface wear caused by prolonged and frequent use. This uniform application of lubricating oil effectively prevents the limit arm 2 from jamming or becoming uneven during movement, thus significantly improving the overall operating performance of the limit arm 2. This lubrication measure also significantly extends the service life of the limit arm 2, allowing it to maintain good working condition even after long-term use, further enhancing the reliability and durability of the limit arm 2.

[0044] It should also be noted that, through the configuration of the oil injection component 7, when the roller b59 is squeezed and driven by the limiting protrusions a54 and b55, the closed state of the seepage hole can be effectively released, and the lubricating oil can flow smoothly to the surface of the limiting arm 2. In conjunction with the brush roller 62, the lubricating oil is evenly applied to the surface of the limiting arm 2, thereby significantly improving the lubrication effect on the limiting arm 2. This not only ensures the accurate delivery of lubricating oil, but also further optimizes the smoothness of the operation of the limiting arm 2 and extends its service life.

[0045] The principle of applying lubricating oil to the limiting arm 2 using the lubrication assembly is as follows: the brush roller 62 absorbs the lubricating oil in the oil storage box 61, so that when the limiting arm 2 moves, the brush roller 62 applies the lubricating oil to the surface of the limiting arm 2. When the pulley 75 is squeezed and driven by the limiting protrusions a54 and b55, the connecting plate 74 moves upward along the through groove 73. At this time, the spring b77 is in a compressed state, thereby driving the baffle 71 to move synchronously, thereby releasing the closed state of the permeation hole 72, causing the lubricating oil to flow into the limiting arm 2 along the permeation hole 72.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
