Description

Technical Field

[0001] The invention relates to the technical field of vehicle door stoppers, and in particular to a vehicle door stopper slider mechanism capable of reducing resistance and increasing energy. Background Art

[0002] In the existing door stopper design, elastic elements such as springs are usually used to control the opening and closing process of the door to achieve the positioning and buffering of the door.

[0003] At present, the traditional door stopper is subjected to greater pressure during the door closing process, resulting in increased friction resistance, which not only affects the smooth closing of the door, but also increases energy consumption and noise. At the same time, due to the limitations of the internal structure of the stopper, the door lacks clear hand feedback during the opening and closing process, and the user cannot accurately perceive the movement state of the door. Summary of the invention

[0004] The object of the present invention is to provide a door stopper slider mechanism capable of reducing resistance and increasing energy, aiming to solve the problem that the limit arm of the traditional door stopper is subjected to greater pressure during the door closing process, resulting in increased friction resistance.

[0005] To achieve the above object, the present invention provides a door limiter slider mechanism capable of reducing resistance and increasing energy, comprising a limiter arm, a limiter box and two slider mechanisms, wherein the slider mechanism comprises a limiter box baffle, a limiter sleeve, a limiter spring, a limiter slider and an auxiliary spring;

[0006] The limiter box is installed on the limiter arm, the limiter box baffle is clamped with the limiter box and is located on the limiter box baffle, the limit sleeve is slidably connected to the limiter box and is located in the limiter box, the limit spring is fixedly connected to the limiter box baffle and is fixedly connected to the limit sleeve and is located between the limiter box baffle and the limiter box, the limit slider is slidably connected to the limit sleeve and is abutted against the limit arm, and the auxiliary spring is fixedly connected to the limit box baffle and is fixedly connected to the limit slider.

[0007] The limiting arm comprises a rotating shaft and a connecting frame, wherein the rotating shaft is rotatably connected to the limiting arm and is located on the limiting arm, and the connecting frame is fixedly connected to the rotating shaft and is located on the rotating shaft.

[0008] Wherein, the limiting arm further has a shock absorbing pad, and the shock absorbing pad is installed on a side of the limiting arm away from the rotating shaft.

[0009] Wherein, the limiting sliding sleeve has a first installation groove and a second installation groove, the first installation groove is used to be installed on the limiting sliding block, and the second installation groove is used to be installed on the limiting spring.

[0010] Wherein, the limiting sliding block has a third installation groove, and the third installation groove is used for installing the auxiliary spring.

[0011] The present invention provides a door limiter slider mechanism that can reduce resistance and increase energy, comprising a limit arm, a limiter box and two slider mechanisms, wherein the slider mechanism comprises a limit box baffle, a limit sleeve, a limit spring, a limit slider and an auxiliary spring; the limiter box is installed on the limit arm, the limit box baffle is clamped with the limiter box and is located on the limit box baffle, the limit sleeve is slidably connected to the limiter box and is located in the limiter box, the limit spring is fixedly connected to the limit box baffle, and is fixedly connected to the limit sleeve, and is located between the limit box baffle and the limiter box, the limit slider is slidably connected to the limit sleeve, and is held against the limit arm, and the auxiliary spring is fixedly connected to the limit box baffle and is fixedly connected to the limit slider. The limit arm provides installation conditions for the limit box, and the limit box provides installation conditions for the two slider mechanisms. The limit spring pre-presses the limit sleeve onto the limit platform at the mouth of the limit box, and the auxiliary spring pre-presses the limit slider onto the limit arm. When the door limiter is in this state, the elastic force of the limit spring cannot be applied to the limit arm, and only the elastic force of the auxiliary spring can be applied to the limit arm through the limit slider. The limit arm is subjected to less pressure, and the corresponding friction resistance of the limit arm movement will be greatly reduced, thereby enhancing the feel of the door when it is opened and closed. When the limit slider slides to the limit feature of the limit arm, the limit slider slides upward and moves together with the limit sleeve. In this state, the elastic force of the limit spring will be applied to the limit slider through the limit sleeve, and applied to the limit arm together with the elastic force of the auxiliary spring. The limit arm will be subjected to a greater pressure, and the force of the limit spring will be significantly increased when applied to the limit arm. The user can have a clear hand feedback when opening and closing the door, thereby solving the problem that the limit arm of the traditional door limiter is subjected to greater pressure during the door closing process, resulting in increased friction resistance.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0018] See also Figures 1 to 3 The present invention provides a door limiter slider mechanism capable of reducing resistance and increasing energy, comprising a limiter arm 1, a limiter box 2 and two slider mechanisms, wherein the slider mechanism comprises a limiter box baffle 3, a limiter sleeve 4, a limiter spring 5, a limiter slider 6 and an auxiliary spring 7;

[0019] The limit box 2 is installed on the limit arm 1, the limit box baffle 3 is clamped with the limit box 2 and is located on the limit box baffle 3, the limit sleeve 4 is slidably connected to the limit box 2 and is located in the limit box 2, the limit spring 5 is fixedly connected to the limit box baffle 3 and to the limit sleeve 4, and is located between the limit box baffle 3 and the limit box 2, the limit slider 6 is slidably connected to the limit sleeve 4 and is abutted against the limit arm 1, and the auxiliary spring 7 is fixedly connected to the limit box baffle 3 and to the limit slider 6.

[0020] In this embodiment, the limit arm 1 provides installation conditions for the limit box 2, and the limit box 2 provides installation conditions for the two slider mechanisms. The limit spring 5 pre-presses the limit sleeve 4 onto the limit platform at the mouth of the limit box 2, and the auxiliary spring 7 pre-presses the limit slider 6 onto the limit arm 1. When the door limiter is in this state, the elastic force of the limit spring 5 cannot be applied to the limit arm 1, and only the elastic force of the auxiliary spring 7 can be applied to the limit arm 1 through the limit slider 6. The limit arm 1 is subjected to little pressure, and the corresponding friction resistance of the limit arm 1 movement will be greatly reduced, thereby enhancing the feel of the door switch. When the limit slider 6 slides to the limit feature of the limit arm 1, the limit slider 6 slides upward and moves together with the limit sleeve 4. In this state, the elastic force of the limit spring 5 will be applied to the limit slider 6 through the limit sleeve 4, and applied to the limit arm 1 together with the elastic force of the auxiliary spring 7. The limit arm 1 will be subjected to a large pressure, and the force of the limit spring 5 will be significantly increased when applied to the limit arm 1. The user can have a clear hand feedback when opening and closing the door, thereby solving the problem that the limit arm of the traditional door limiter is subjected to a large pressure during the door closing process, resulting in increased friction resistance.

[0021] Furthermore, the limiting arm 1 has a rotating shaft 8 and a connecting frame 9, the rotating shaft 8 is rotatably connected to the limiting arm 1 and is located on the limiting arm 1, and the connecting frame 9 is fixedly connected to the rotating shaft 8 and is located on the rotating shaft 8.

[0022] In this embodiment, the rotating shaft 8 provides installation conditions for the connecting frame 9, and the limiting arm 1 can be connected to the vehicle body through the connecting frame 9.

[0023] Furthermore, the limiting arm 1 also has a shock-absorbing pad 10 , and the shock-absorbing pad 10 is installed on a side of the limiting arm 1 away from the rotating shaft 8 .

[0024] In this embodiment, the shock absorbing pad 10 can be used to buffer and reduce shock on the limiting arm 1 .

[0025] Furthermore, the limiting sliding sleeve 4 has a mounting groove 11 and a mounting groove 2 12 , wherein the mounting groove 11 is used to be mounted on the limiting sliding block 6 , and the mounting groove 2 12 is used to be mounted on the limiting spring 5 .

[0026] In this embodiment, the installation groove 1 1 can be used to install the limit slider 6 , so that the limit slider 6 can move in the limit sleeve 4 , and the installation groove 2 12 is used to install the limit spring 5 .

[0027] Furthermore, the limiting slider 6 has a mounting groove 3 13 , and the mounting groove 3 13 is used to install the auxiliary spring 7 .

[0028] In this embodiment, the installation groove three 13 can be used to install the auxiliary spring 7.

[0029] The limit arm 1 provides installation conditions for the limit box 2, and the limit box 2 provides installation conditions for the two slider mechanisms. The limit spring 5 pre-presses the limit sleeve 4 onto the limit platform at the mouth of the limit box 2, and the auxiliary spring 7 pre-presses the limit slider 6 onto the limit arm 1. When the door limiter is in this state, the elastic force of the limit spring 5 cannot be applied to the limit arm 1, and only the elastic force of the auxiliary spring 7 can be applied to the limit arm 1 through the limit slider 6. The limit arm 1 is subjected to less pressure, and the corresponding friction resistance of the limit arm 1 movement will be greatly reduced, thereby enhancing the feel of the door switch. When the limit slider 6 slides to the limit feature of the limit arm 1, the limit slider 6 slides upward and moves together with the limit sleeve 4. In this state, the elastic force of the limit spring 5 will be applied to the limit slider 6 through the limit sleeve 4, and applied to the limit arm 1 together with the elastic force of the auxiliary spring 7. The limit arm 1 will be subjected to a large pressure, and the force of the limit spring 5 will be significantly increased when applied to the limit arm 1. The user can have a clear hand feedback when opening and closing the door, thereby solving the problem that the limit arm of the traditional door limiter is subjected to a large pressure during the door closing process, resulting in increased friction resistance.

[0030] The door stopper slider mechanism provided by the present invention, which can reduce resistance and increase energy, has the following beneficial effects:

[0031] 1. The present invention provides a door limiter slider mechanism that can reduce resistance and increase energy, and significantly reduces friction resistance: The slider mechanism design of the present invention, through the reasonable configuration of the limit spring and the auxiliary spring, enables the auxiliary spring to provide pre-pressure in the initial stage of closing the door, and the pressure on the limit arm is relatively small, thereby greatly reducing friction resistance and improving the smoothness and feel of door opening and closing.

[0032] 2. The door limiter slider mechanism provided by the present invention can reduce resistance and increase energy and provide clear hand-feel feedback: when the door is closed to a certain position, the limit slider slides to the limit feature of the limit arm, and the limit slider moves together with the limit sleeve, and the elastic force of the limit spring is applied to the limit slider through the limit sleeve, and acts together with the elastic force of the auxiliary spring to subject the limit arm to a large pressure. This change in pressure provides the user with clear hand-feel feedback, allowing the user to clearly perceive the closed state of the door.

[0033] 3. The door stopper slider mechanism provided by the present invention can reduce resistance and increase energy, and enhance structural stability and durability: The door stopper slider mechanism of the present invention has a reasonable structural design, and the connection between the components is stable and reliable, and can withstand large forces and pressures, and is not prone to deformation or damage. At the same time, the setting of the shock-absorbing pad further enhances the durability of the stopper arm and prolongs the service life of the door stopper.

[0034] 4. The door stopper slider mechanism provided by the present invention can reduce resistance and increase energy to improve user experience: By optimizing the design of the door stopper, the present invention not only solves the problems existing in the traditional door stopper, but also improves the user experience. The door opening and closing is smoother and the hand feel is more comfortable, so that the user can experience a more advanced and convenient operation experience when opening and closing the door.
