Description

Technical Field

[0001] The utility model relates to the field of vehicle position limiters, in particular to a novel position limiter for vehicle doors. Background Technique

[0002] A position limiter is a mechanical or electronic device. A vehicle door position limiter is a device that opens and holds a vehicle door at a certain angle, mainly used to control and limit the maximum or minimum position reached by an object during movement, and mainly used to limit the position of the vehicle door relative to the vehicle body when the vehicle door is opened, so that the vehicle door is in the required position when opened.

[0003] However, most traditional vehicle door position limiters cannot adjust the clamping tightness of the position limiter according to the usage requirements during use. After being used for a long time, the clamping tightness of the position limiter will become poor, resulting in the user being unable to clearly perceive the distinction between the positions limited by each part of the position limiter, which reduces the service life of the position limiter.

[0004] Therefore, those skilled in the art have provided a novel position limiter for vehicle doors to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a novel position limiter for vehicle doors is proposed. Compared with most traditional vehicle door position limiters, an adjustable push plate is arranged in the main body mechanism of this vehicle door position limiter. Under the action of gear meshing, the user can control the rotation of the threaded rod through the rotating block, thereby adjusting the distance between the push plate and the clamping slider, so that the force exerted by the spring on the clamping slider changes. Therefore, after being used for a long time, the user only needs to control the rotating block to adjust the clamping force of the position limiter, and then the user can clearly perceive the change of the vehicle door reaching each limited position during use, reducing the reduction of the perception degree during position change, and improving the service life of the position limiter.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A novel position limiter for vehicle doors includes an arm rod mechanism, a main body mechanism, and a lubrication mechanism. The main body mechanism includes a housing. The outer wall of the front end of the housing is fixedly connected with a cover plate. Limiting chutes are opened at both the upper and lower parts of the outer wall of the front end of the housing. The lower end of the inner wall of the limiting chute is slidably connected with a clamping slider. A spring is arranged in the middle of the upper surface of the clamping slider. The center of the inner top surface of the limiting chute is rotatably connected with a threaded rod. The lower end of the outer wall of the threaded rod is in threaded fit with a push plate;

[0008] The upper end of the outer wall of the threaded rod is fixedly connected with a first bevel gear. The upper and lower ends of the outer wall of one side of the housing are both rotatably connected with rotating blocks. The outer wall of one side of the rotating block is fixedly connected with a large bevel gear. The upper and lower ends of the inside of the housing are both rotatably connected with first rotating rods. The outer walls of the front and rear ends of the first rotating rod are both fixedly connected with second bevel gears. The rear end inside the housing is rotatably connected with a second rotating rod. The upper and lower ends of the outer wall of the second rotating rod are both fixedly connected with third bevel gears;

[0009] The lubricating mechanism includes a fixing plate. A placement groove is opened in the middle of the outer wall of one side of the fixing plate. Brushes are fixedly connected to the inner top surface and the inner bottom surface of the placement groove. A chamber is opened in the upper end of the fixing plate. A plurality of through holes are opened in the inner bottom surface of the chamber.

[0010] Through the above technical solution, compared with most traditional limiters for automobile doors, this limiter for automobile doors is provided with a lubricating mechanism. The user can convey the lubricating oil liquid into the chamber through the liquid inlet on the conveying pipeline. Under the action of the through holes, the oil liquid soaks onto the brushes, so that the main arm rod can be continuously lubricated by the brushes when the car door is opened and closed, thereby increasing the lubrication time of the limiter. Moreover, by removing the cover plate, the user can maintain and repair the components inside the main body mechanism, thus improving the convenience of maintaining the limiter.

[0011] Furthermore, the arm rod mechanism includes a main arm rod. A limit stop block is fixedly connected to the outer wall of one side of the main arm rod. Buffer pads are fixedly connected to the upper and lower ends of the outer wall of the limit stop block close to the main arm rod;

[0012] Through the above technical solution, the limiter can limit the car door at multiple different positions.

[0013] Furthermore, a fixing block is hingedly connected to the outer wall of the main arm rod far from the limit stop block;

[0014] Through the above technical solution, the limiter can be fixed on the vehicle body.

[0015] Furthermore, a plurality of fixing screws are arranged around the outer wall of the front end of the cover plate. A positioning block is fixedly connected to the middle of the outer wall of the rear end of the cover plate;

[0016] Through the above technical solution, the user can remove the cover plate more conveniently, and then the user can maintain the components inside the main body mechanism more conveniently.

[0017] Furthermore, fixing feet are fixedly connected to one side of the upper surface and the lower surface of the housing;

[0018] Through the above technical solution, the housing can be fixed on the car door by setting the fixed feet.

[0019] Further, the push plate slides inside the limit chute, and the first bevel gear and the large bevel gear are in gear engagement;

[0020] Through the above technical solution, the user can control the movement of the push plate through the rotating block, and the large bevel gear is larger than other gears, so the first bevel gear and the second bevel gear do not affect each other.

[0021] Further, the large bevel gear and the second bevel gear are in gear engagement, and the second bevel gear and the third bevel gear are in gear engagement;

[0022] Through the above technical solution, the rotating block can rotate synchronously with another rotating block through the first rotating rod and the second rotating rod, so that the two clamping sliders can move towards each other synchronously.

[0023] Further, a conveying pipe is fixedly connected to the center of the upper surface of the fixed plate, and a liquid inlet is fixedly connected to one end of the conveying pipe away from the fixed plate;

[0024] Through the above technical solution, the user can convey the lubricating oil liquid into the conveying pipe through the liquid inlet and then convey it onto the fixed plate.

[0025] The utility model has the following beneficial effects:

[0026] 1. A novel limiter for an automobile door proposed by the utility model, compared with most traditional limiters for automobile doors, this limiter for an automobile door is provided with an adjustable push plate in the main body mechanism. Under the action of gear engagement, the user can control the rotation of the threaded rod through the rotating block, thereby adjusting the distance between the push plate and the clamping slider, so that the force exerted by the spring on the clamping slider changes. Therefore, after the limiter has been used for a long time, the user only needs to control the rotating block to adjust the clamping force of the limiter, so that the user can more clearly perceive the changes in the door reaching each limited position during the use of the limiter, reduce the reduction in perception during position changes, and improve the service life of the limiter.

[0027] 2. The utility model proposes a new type of limiter for automobile doors. Compared with most traditional limiters for automobile doors, the limiter for automobile doors is provided with a lubrication mechanism. The user can deliver the lubricating oil into the chamber through the liquid inlet on the delivery pipe. The oil is soaked into the brush under the action of the through hole, so that the main arm can be continuously lubricated by the brush when the door is opened and closed, thereby increasing the lubrication time of the limiter, and the user can maintain the components inside the main mechanism by removing the cover plate, thereby improving the convenience of maintenance of the limiter.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Referring to Figures 1-5 , an embodiment provided by the present invention:

[0037] A new type of limiter for an automobile door, comprising an arm rod mechanism 1, a main body mechanism 2 and a lubrication mechanism 3. The arm rod mechanism 1 includes a main arm rod 101. A limiting block 102 is fixedly connected to the outer wall of one side of the main arm rod 101. Buffer pads 103 are fixedly connected to both the upper and lower ends of the outer wall of the limiting block 102 close to one side of the main arm rod 101, so that the limiter can limit the door at multiple different positions. A fixed block 104 is hingedly connected to the outer wall of the main arm rod 101 away from the limiting block 102, so that the limiter can be fixed on the vehicle body. The main body mechanism 2 includes a housing 201. A cover plate 202 is fixedly connected to the outer wall of the front end of the housing 201. Limiting chutes 206 are provided in both the upper and lower parts of the outer wall of the front end of the housing 201. A clamping slider 207 is slidably connected to the lower end of the inner wall of the limiting chute 206. A spring 208 is arranged in the middle of the upper surface of the clamping slider 207. A threaded rod 2010 is rotatably connected to the center of the inner top surface of the limiting chute 206. A push plate 209 is in threaded cooperation with the lower end of the outer wall of the threaded rod 2010;

[0038] The upper end of the outer wall of the threaded rod 2010 is fixedly connected with a first bevel gear 2011. Rotating blocks 2012 are rotatably connected to both the upper and lower ends of the outer wall of one side of the housing 201. A large bevel gear 2013 is fixedly connected to the outer wall of one side of the rotating block 2012. First rotating rods 2014 are rotatably connected to both the upper and lower ends of the inside of the housing 201. Second bevel gears 2015 are fixedly connected to the outer walls of the front and rear ends of the first rotating rod 2014. A second rotating rod 2016 is rotatably connected to the rear end of the inside of the housing 201. Third bevel gears 2017 are fixedly connected to both the upper and lower ends of the outer wall of the second rotating rod 2016;

[0039] The lubrication mechanism 3 includes a fixing plate 301. A placement groove 302 is provided in the middle of the outer wall of one side of the fixing plate 301. Brushes 303 are fixedly connected to both the inner top surface and the inner bottom surface of the placement groove 302. A chamber 304 is provided in the upper end of the fixing plate 301. A plurality of through holes 305 are provided in the inner bottom surface of the chamber 304.

[0040] Compared with most traditional door limiters for automobiles, this door limiter for automobiles is provided with an adjustable push plate 209 inside the main body mechanism 2. Under the action of gear meshing, the user can control the rotation of the threaded rod 2010 by rotating the block 2012, thereby adjusting the distance between the push plate 209 and the clamping slider 207, so that the force exerted by the spring 208 on the clamping slider 207 changes. Thus, after the limiter has been used for a long time, the user only needs to control the rotating block 2012 to adjust the clamping force of the limiter. Furthermore, when the limiter is in use, the user can more clearly perceive the changes in the door reaching each limited position, reducing the decrease in the perception degree during position changes, and improving the service life of the limiter.

[0041] A plurality of fixing screws 203 are arranged on the periphery of the front outer wall of the cover plate 202, and a positioning block 204 is fixedly connected to the middle of the rear outer wall of the cover plate 202, so that the user can disassemble the cover plate 202 more conveniently, and further the user can maintain the internal components of the main body mechanism 2 more conveniently. Fixed feet 205 are fixedly connected to one side of the upper surface and the lower surface of the housing 201. By providing the fixed feet 205, the housing 201 can be fixed on the car door. The push plate 209 slides inside the limit chute 206. The first bevel gear 2011 and the large bevel gear 2013 are in gear meshing, so that the user can control the movement of the push plate 209 by rotating the block 2012. And the large bevel gear 2013 is larger than other gears, so the first bevel gear 2011 and the second bevel gear 2015 do not affect each other. The large bevel gear 2013 and the second bevel gear 2015 are in gear meshing, and the second bevel gear 2015 and the third bevel gear 2017 are in gear meshing, so that the rotating block 2012 can rotate synchronously with another rotating block 2012 through the first rotating rod 2014 and the second rotating rod 2016, and further the two clamping sliders 207 can move synchronously towards each other. A conveying pipe 306 is fixedly connected to the center of the upper surface of the fixing plate 301. One end of the conveying pipe 306 far from the fixing plate 301 is fixedly connected with a liquid inlet 307, so that the user can convey the lubricating oil liquid into the conveying pipe 306 through the liquid inlet 307 and then convey it onto the fixing plate 301.

[0042] Working principle: First, fix the limiter between the car door and the vehicle body. Under the action of the spring 208, the clamping slider 207 applies pressure to the main arm rod 101, so that the user can perceive the changes in the positions of the car door at various defined positions when opening and closing the door. The change in pressure can also cause a change in the clarity of perception by the user, which enables the user to adjust the pressure applied to the clamping slider 207 through the rotating block 2012 according to the usage requirements. Then, by injecting lubricating liquid into the lubrication mechanism 3, the brush 303 can always be kept moist to continuously lubricate the main arm rod 101 and reduce the friction noise caused by long-term use.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
