Description

Technical Field

[0001] The utility model relates to the technical field of automobile safety, in particular to a door limiter. Background Art

[0002] With the increase in car collision accidents year by year, serious economic losses and casualties have been caused, especially safety accidents caused by directly opening the car door due to negligence and failure to promptly pay attention to the pedestrians and vehicles behind, which account for a large proportion of traffic accidents.

[0003] The current vehicle usage situation is as follows: when you need to get off the vehicle, you only need to unlock and open the door after parking it by the side of the road. However, during the process of opening the door, most of the door limiters on the market do not have a locking function. Abnormal opening of the door may cause damage to the vehicle and personal safety. Summary of the invention

[0004] The main purpose of the utility model is to overcome the deficiencies in the prior art and provide a vehicle door limiter.

[0005] The technical solution adopted by the utility model to achieve its technical purpose is: a door stopper, including a stopper main arm, a stopper box is sleeved on one end of the stopper main arm, mounting grooves are opened at both ends of the limit box, a compression spring is fixedly installed inside the mounting groove, a slider is fixed on one end of the compression spring, and the slider is pressed on the stopper main arm by the pressing force of the compression spring;

[0006] The other end of the main arm of the limiter is provided with a limit groove matching the slider;

[0007] When the main arm of the limiter moves left and right to open the door, the slider can be located in the limit slot, so that the door can be opened and locked.

[0008] A fixing groove inside the limit box is provided on one side of the installation groove, and a locking solenoid valve is fixed inside one of the fixing grooves;

[0009] One end of the main arm of the limiter is provided with a slot corresponding to and matching the valve needle at the telescopic end of the locking solenoid valve;

[0010] The locking solenoid valve is connected to the on-board computer in the car. When the on-board computer detects a moving object at the rear side, the locking solenoid valve locks its telescopic end valve needle in the slot of the limiter main arm, so that the door cannot be opened when there is a moving object at the rear side.

[0011] Preferably, a fixing piece is hingedly connected to the side wall at one end of the main arm of the limiter, and a limit baffle is fixed to the side wall at the other end, the fixing piece is used to connect to the vehicle door, and the limit baffle is used for limiting.

[0012] Preferably, there are at least four limit grooves at the other end of the limiter main arm, and they are symmetrically arranged up and down. Through the arrangement of the limit grooves, the door can be opened at different angles with certain restrictions.

[0013] Preferably, a damping solenoid valve is fixed inside another of the fixing grooves;

[0014] The limit box is also provided with a connecting groove connected with another fixed groove and the installation groove, a pillar is fixed inside the connecting groove, a seesaw is rotatably arranged on one side of the pillar and rotates around it, the seesaw is tilted and has push plates at both ends, both ends of the push plate seesaw are kept in contact, one of the push plates is fixed to the compression spring, and the other is fixed to the telescopic end valve needle of the damping solenoid valve; the telescopic end valve needle of the damping solenoid valve can make the seesaw rotate around the pillar, so that the seesaw presses the compression spring downward, increasing the friction between the slider and the main arm of the limiter, so that the resistance when opening the car door can be adjusted.

[0015] Preferably, a mounting bolt is fixed to one side of the limit box, and the limit box is fixed in the frame by the mounting bolt.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The door limiter has an electromagnetic locking function and is suitable for door anti-collision controlled by the vehicle computer. It provides a solution for abnormal door opening, optimizes anti-collision control, and effectively solves the problem of vehicle damage and personal safety caused by abnormal door opening. It is easy to install and is suitable for installation and modification of a wide range of vehicle models as well as upgrades and improvements to subsequent vehicle models.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] In the description of the present utility model, it should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

In addition, the terms "first", "second", "third" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The meaning of "several" is one or more, unless otherwise clearly and specifically defined.

[0026] In the description of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1

[0027] like Figure 1-2 As shown, a door stopper includes a stopper main arm 1, a fixing member 103 is hinged on one end side wall of the stopper main arm 1, and a limit baffle 104 is fixed on the other end side wall. The fixing member 103 is used to connect to the door, and the limit baffle 104 is used for limiting.

[0028] A limit box 2 is sleeved on one end of the limiter main arm 1, and installation grooves 201 are provided at both ends of the interior of the limit box 2. A compression spring 203 is fixedly installed inside the installation groove 201, and a slider 204 is fixed at one end of the compression spring 203. The slider 204 is pressed against the limiter main arm 1 by the pressing force of the compression spring 203; a limit groove 101 matching the slider 204 is provided at the other end of the limiter main arm 1. There are at least four limit grooves 101 at the other end of the limiter main arm 1, and they are symmetrically arranged up and down. Through the arrangement of the limit grooves, the car door can be opened at different angles with certain restrictions. When the limiter main arm 1 moves left and right to open the car door, the slider 204 can be located in the limit groove, so that the car door can be opened and locked.

[0029] At the same time, the diameters of the two ends of the limiter main arm 1 are different, so that the door can be at about 60 degrees, and the slider 204 can just hit the slope position of the limiter main arm 1, so that the door has a greater damping effect when it is opened.

[0030] One side of the mounting groove 201 is provided with a fixing groove 205 inside the limit box 2, and a locking solenoid valve 4 is fixed inside one of the fixing grooves 205, and one end of the limiter main arm 1 is provided with a card slot 102 corresponding to the telescopic end valve needle of the locking solenoid valve 4; the locking solenoid valve 4 is connected to the on-board computer in the vehicle, and when the on-board computer detects a moving object at the side and rear, the locking solenoid valve 4 locks its telescopic end valve needle in the card slot 101 of the limiter main arm 1, thereby preventing the door from being opened when there is a moving object at the side and rear.

[0031] A mounting bolt 202 is fixed to one side of the limit box 2, and the limit box 2 is fixed in the frame by the mounting bolt 202.

[0032] The working principle and specific usage process of the door limiter are as follows: a locking solenoid valve 4 is provided on one side of the limit box 2. When the door is fully closed, the locking solenoid valve 4 is energized, and the valve needle of the locking solenoid valve 4 extends out of the main arm of the locking limiter; when the car is parked and the door needs to be opened, if the on-board computer detects that there is an object approaching and moving from the rear, the locking solenoid valve 4 is locked and the door cannot be opened; when the car is parked and the door needs to be opened, if the on-board computer detects that there is no object approaching and moving from the rear, the valve needle of the locking solenoid valve 4 is released and the door can be opened. Example 2

[0033] like Figure 1-2 As shown, in the door stopper, a locking solenoid valve 4 is fixed inside one of the fixing grooves 205, and a damping solenoid valve 3 is fixed inside the other fixing groove 205;

[0034] The interior of the limit box 2 is also provided with a connecting groove 206 connected with another fixed groove 205 and the installation groove 201, and a pillar 501 is fixed inside the connecting groove 206. A seesaw 5 rotating around the pillar 501 is rotatably arranged on one side of the pillar 501. The seesaw 5 is tilted and has push plates 502 at both ends. The push plates 502 keep the two ends of the seesaw 5 in contact, one of the push plates 502 is fixed to the compression spring 203, and the other is fixed to the telescopic end valve needle of the damping solenoid valve 3; the telescopic end valve needle of the damping solenoid valve 3 can make the seesaw 5 rotate around the pillar 501, so that the seesaw 5 presses the compression spring 203 downward, thereby increasing the friction between the slider 204 and the limiter main arm 1, so that the resistance when opening the car door can be adjusted.

[0035] Specifically, when it is necessary to increase the resistance when the door is opened, the damping solenoid valve 3 is opened to extend the valve needle at its telescopic end toward one side of the push plate 502, so that the push plate 502 at the top of the damping solenoid valve 3 lifts one end of the seesaw 5. Since the seesaw 5 rotates around one side of the pillar 501, the other end of the seesaw 5 drops, and the other end of the seesaw 5 presses the other compression spring 203 downward, so that the friction between the other slider 204 and the limiter main arm 1 increases, thereby increasing the resistance when the door is opened; conversely, if the valve needle at the telescopic end of the damping solenoid valve 3 is lowered, the compression spring 203 can be rotated in the opposite direction against the seesaw 5, so that the clamping force of the compression spring 203 becomes smaller, thereby reducing the friction between the slider 204 and the limiter main arm 1.

[0036] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structures, equivalent processes or equivalent functional transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of protection of the utility model patent.
