Door stopper with oil storage function

Abstract

The present invention relates to a door stopper with an oil storage function, comprising a stopper arm symmetrically provided with two functional surfaces, and a stopper assembly slidably sleeved on the stopper arm; wherein the stopper assembly comprises a stopper housing, a stopper slider symmetrically provided on both sides of the stopper arm, an oil storage tank opened at the center of the sliding end of the stopper slider, and oil-blocking ribs arranged in parallel on both sides of the oil storage tank and in sliding contact with the functional surface, and the oil-blocking ribs extend along the width direction of the stopper arm. Compared with the prior art, the present invention forms an oil-limiting tank for storing lubricating grease by arranging two oil-blocking ribs in parallel at the sliding end of the stopper slider, so that when the stopper slider slides, the grease in the oil-limiting tank is always present and will not overflow and be lost due to multiple sliding, thereby ensuring the sliding effect; at the same time, by reducing the contact area between the stopper slider and the stopper arm, the sliding resistance is reduced, thereby improving the closing-assisting energy of the stopper and ensuring a good user experience.

Description

Technical Field

[0001] The invention belongs to the technical field of automobile accessories and relates to a door stopper with an oil storage function. Background Art

[0002] Door limiters are usually installed on car doors. On the one hand, they are used to limit the opening angle of the door, including limiting the maximum opening of the door and stabilizing the door position at the designed opening and closing angle; on the other hand, they are used to provide door closing assistance to ensure user experience. The door limiter usually includes a limit arm 1 and a limit slider 2 (such as a slider) that is clamped and fixed on both sides of the limit arm 1 and in sliding contact with the limit arm 1. Figure 1 As shown). Its working principle is as follows: one end of the limit arm 1 is hinged to the vehicle body, the limit slider 2 is fixed to the vehicle door through the limiter housing, and the limit slider 2 is pressed against the limit arm 1 by the elastic force of the spring; when the vehicle door is opened, the limiter housing will rotate around the hinge end with the vehicle door, and because the rotation axis of the hinged end of the vehicle door is not coaxial with the rotation axis of the vehicle door, the limit slider 2 will move outward along the limit arm 1 with the rotation of the vehicle door until it abuts against the limit block at the end of the limit arm 1; at the same time, due to the high and low grooves made on the limit arm 1, the limit slider 2 will tend to stabilize at the lower end of the groove under the action of the elastic force, so that the vehicle door is stabilized at the designed opening angle.

[0003] When the limit slider runs on the functional surface of the limit arm, oil is usually applied to the slider head to ensure the sliding contact effect. However, during the operation, the slider will push the grease to both ends of the limit arm, resulting in a reduction in the grease on the functional surface, thereby increasing friction and reducing the closing energy. Summary of the invention

[0004] The purpose of the present invention is to provide a door stopper with oil storage function.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A door stopper with an oil storage function, comprising a stopper arm symmetrically provided with two functional surfaces, and a stopper assembly slidably sleeved on the stopper arm;

[0007] The limiter assembly includes a limiter housing, and a limiter mechanism symmetrically arranged in the limiter housing and located on both sides of the limiter arm; the limiter mechanism includes a limiter slider whose end is in sliding contact with the functional surface, and an oil storage component arranged on the sliding end of the limiter slider;

[0008] The oil storage assembly comprises an oil storage tank opened at the center of the end portion, and oil retaining ribs arranged in parallel on both sides of the oil storage tank. The oil retaining ribs extend along the width direction of the limiting arm and are in sliding contact with the functional surface.

[0009] Furthermore, the extension length of the oil-blocking rib is consistent with the width of the functional surface.

[0010] Furthermore, the oil-blocking rib is a straight strip rib with a semicircular cross-section.

[0011] Furthermore, the oil storage tank is a hemispherical tank.

[0012] Furthermore, the side wall of the limit slider is provided with a guide rib, and the inner wall of the limiter housing is provided with a guide groove matched with the guide rib.

[0013] Furthermore, a plurality of guide ribs are arranged in parallel along the circumferential direction on the side wall of the limit slider.

[0014] Furthermore, an elastic member installation groove is provided on the side of the limit sliding block opposite to the sliding end, and a limit elastic member is further provided between the elastic member installation groove and the limiter housing.

[0015] Furthermore, the limiting elastic member is a spring.

[0016] Furthermore, the functional surface is a wavy functional surface.

[0017] Furthermore, one end of the limit arm is provided with a hinged seat, and the other end is provided with a T-shaped stop seat.

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

[0019] 1) The present invention forms an oil limiting groove for storing lubricating grease by arranging two oil-blocking ribs in parallel at the sliding end of the limit slider, so that when the limit slider slides, the grease in the oil limiting groove is always present and will not overflow and be lost due to multiple sliding, thereby ensuring the sliding effect; at the same time, the contact area between the limit slider and the limit arm is reduced, the sliding resistance is reduced, thereby improving the closing energy of the limiter and ensuring a good user experience;

[0020] 2) The present invention uses the limiting effect between the guide ribs on the side wall of the limit slider and the guide groove on the inner wall of the limiter housing to prevent the limit slider from rotating due to telescopic displacement when passing through the functional surface, and further deflecting the oil-blocking ribs due to the rotation, and forming a gap between the oil-limiting groove and the functional surface, causing the lubricating grease to flow out, thereby ensuring the sliding effect.

[0027] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0028] Example:

[0029] like Figure 2 The door stopper with oil storage function shown in the figure comprises a stopper arm 1 symmetrically provided with two wavy functional surfaces, and a stopper assembly slidably sleeved on the stopper arm 1.

[0030] Among them, one end of the limit arm 1 is provided with an articulated seat 4 fixedly connected to the vehicle body, and the other end is provided with a T-shaped stopper seat 5 for limiting the sliding distance of the limiter assembly. The limiter assembly includes a limiter housing, and a limit mechanism symmetrically arranged in the limiter housing and located on both sides of the limiter arm 1. The limit mechanism includes a limit slider 2 whose end is in sliding contact with the functional surface, and an oil storage assembly arranged on the sliding end of the limit slider 2.

[0031] like Figure 3 As shown, an elastic member installation groove is provided on the side opposite to the sliding end of the limit slider 2, and a limit elastic member 6 is provided between the elastic member installation groove and the limiter housing. The limit elastic member 6 provides clamping pressure so that the limit sliders 2 on both sides can clamp the limit arm 1 and maintain a good sliding contact effect with the functional surface. In this embodiment, the limit elastic member 6 is a spring.

[0032] like Figure 3 As shown, the oil storage assembly includes a hemispherical oil storage tank 7 opened at the center of the end, and oil blocking ribs 8 arranged in parallel on both sides of the oil storage tank 7. The oil blocking ribs 8 are straight strip ribs with a semicircular cross-section, and extend along the width direction of the limit arm 1, and the extension length thereof is consistent with the width of the functional surface.

[0033] like Figure 4As shown, the limit slider 2 is in sliding contact with the functional surface of the limit arm 1 through the oil-blocking ribs 8, and an oil-blocking groove is formed between the two oil-blocking ribs 8, so that when the limit slider 2 slides, the grease in the oil-blocking groove is always present and will not overflow and be lost due to multiple sliding. In addition, the contact area between the limit slider 2 and the limit arm 1 is reduced by the oil-blocking ribs 8, which helps to improve the closing energy of the limiter.

[0034] In addition, in order to further ensure that the oil-blocking rib 8 is perpendicular to the length direction of the functional surface, a guide rib 3 is provided on the side wall of the limit slider 2, and a guide groove matched with the guide rib 3 is provided on the inner wall of the limiter housing, thereby preventing the limit slider 2 from rotating due to telescopic displacement when passing through the groove of the functional surface, thereby preventing the oil-blocking rib 8 from deflecting and the lubricating oil from flowing out of the gap caused by the deflection.

[0035] In other embodiments, three guide ribs 3 are evenly arranged along the circumferential direction on the side wall of the limiting slider 2 to assist each other in providing a guiding effect.

[0036] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
