Description

Technical Field

[0001] The utility model relates to the field of passenger cars, and particularly to a telescopic door limiter. Background Art

[0002] The function of the door limiter is to limit the maximum opening degree of the door to ensure that the door will not collide with other structures of the vehicle body. At the same time, the door limiter is also used to achieve different opening degrees of the door and keep the door stable at different opening degrees.

[0003] However, at present, the door limiters with traditional structures have some defects:

[0004] 1. At present, the limiter structure of automobile doors is mostly realized by the relative sliding between the housing and the limiting arm. During the process of opening and closing the door, the limiting arm will extend into the inner cavity of the door, which requires a high space for the inner cavity of the door and is not conducive to the realization of the vehicle body shape.

[0005] 2. The slider and the limiting arm slide relative to each other, and there are grooves on the limiting arm, where dust is extremely easy to accumulate, thus generating abnormal noises. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the above defects and propose a telescopic door limiter with a telescopic structure.

[0007] To achieve the above purpose, the utility model is realized as follows:

[0008] A telescopic door limiter includes a vehicle body connecting piece, a retractable rod, and a door connecting piece. Among them, the vehicle body connecting piece and the door connecting piece are respectively rotatably connected to both ends of the retractable rod. By stretching or contracting the retractable rod, the vehicle body connecting piece and the door connecting piece are made to approach or move away from each other.

[0009] For the telescopic door limiter, the door connecting piece includes a support and a rotating shaft. The rotating shaft is rotatably arranged in the support, and the door connecting piece is connected to the retractable rod through the rotating shaft.

[0010] For the telescopic door limiter, the retractable rod includes rod segments sleeved axially in sequence and spring fins and limiting grooves respectively arranged at the tails of each rod segment. When the retractable rod is unfolded or contracted, each rod segment is positioned by making the spring fins on each rod segment embed into the limiting grooves.

[0011] This telescopic door limiter has the following advantages:

[0012] 1. The telescopic rod is made of metal or high-strength plastic, and a limiting groove is opened on each telescopic rod. The steel column and the spring elastic sheet are connected to the inner side of the telescopic rod, and different opening degree limiting requirements are realized by the steel column being stuck into the card slot.

[0013] 2. Different gear forces are achieved by adjusting the elastic force of the spring, the size of the spring leaf, and the R-angle design of the limit groove.

[0014] 3. The telescopic rod is on the outer side of the car door and will not extend into the inner cavity of the car door, avoiding affecting the inner glass, sheet metal and other mating parts in the car, and providing more room for choice in the design of the vehicle body shape and car door accessories.

[0015] 4. After the spring leaf slides out of the limit groove, there is only point contact with the telescopic rod. During the movement process, the resistance is greatly reduced, the feeling of opening and closing the door is easier, and the gear lever is more obvious.

[0016] 5. Since there is no slider structure and there is only point contact between the steel ball and the telescopic rod, the probability of dust noise is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic structural view of this position limiter. DETAILED DESCRIPTION OF THE INVENTION

[0018] The present utility model will be further described below through specific embodiments.

[0019] As Figure 1 shown, a telescopic car door position limiter includes a vehicle body connecting member 1, a retractable rod 2 and a car door connecting member 3. Among them, the vehicle body connecting member 1 and the car door connecting member 3 are respectively rotatably connected to both ends of the retractable rod 2. By stretching or contracting the retractable rod 2, the vehicle body connecting member 1 and the car door connecting member 3 are brought closer or farther away from each other.

[0020] For the telescopic car door position limiter, the car door connecting member 3 includes a support 31 and a rotating shaft 32. The rotating shaft 32 is rotatably arranged in the support 31, and the car door connecting member 3 is connected to the retractable rod 2 through the rotating shaft 32.

[0021] For the telescopic car door position limiter, the retractable rod 2 includes rod segments 21 sleeved axially in sequence and spring fins 22, limit grooves 23 and steel balls 24 respectively arranged at the tails of each rod segment. When the retractable rod expands or contracts, each rod segment is positioned by embedding the spring fins and the steel balls 24 on each rod segment into the limit grooves.

[0022] This telescopic car door position limiter has the following advantages:

[0023] 1. The telescopic rod is made of metal or high-strength plastic. A limit groove is opened on each telescopic rod. The steel column and the spring leaf are connected to the inner side of the telescopic rod. By clamping the steel column into the card slot, the limit requirements for different opening degrees are realized.

[0024] 2. Different gear forces are achieved by adjusting the elastic force of the spring, the size of the spring leaf, and the R-angle design of the limit groove.

[0025] 3. The telescopic rod is on the outer side of the car door and will not extend into the inner cavity of the car door, avoiding the impact on the inner glass, sheet metal and other mating parts in the car, and providing more options for the body styling and car door accessory design;

[0026] 4. After the elastic piece slides out of the limit groove, there is only a point contact with the telescopic rod, greatly reducing the resistance during the movement process, making the feeling of opening and closing the door easier and the gear lever more obvious;

[0027] 5. Since there is no slider structure and the steel ball has only a point contact with the telescopic rod, the probability of dust noise is greatly reduced.
