[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example, see attached document Figure 1 Appendix Figure 2 This utility model provides a door opening limiter, including a limit box 100 and a limit arm 300. An elastic push block unit 200 is provided inside the limit box 100, as shown in the attached figure. Figure 3 As shown, the elastic pusher unit 200 includes an electromagnetic damper 210, which includes a drive cylinder, a retractable piston rod, and a damping actuator 240 for adjusting the piston rod damping value. A spring 220 is sleeved on the outside of the electromagnetic damper 210. One end of the spring 220 is fixedly connected to the drive cylinder, and the other end is fixedly connected to the piston rod. A limit push head 230 is also fixedly installed at one end of the spring 220. The damping actuator 240 is connected to the vehicle domain controller 400. The vehicle domain controller 400 connects to the vehicle body camera 500 and the vehicle body ranging radar 600. The electromagnetic damper 210 is existing technology; by changing the current or voltage value of the electromagnetic coil via the damping driver 240, the damping value of the piston rod can be changed. Together with the spring 220, the elastic force value of the limit push head 230 can be adjusted. The limit arm 300 passes through the limit box 100 from left to right. The end of the limit push head 230 away from the spring 220 abuts against the limit arm 300. (See attached diagram.) Figure 4As shown, at least one door opening angle positioning groove 310 is arranged on the limiting arm 300, and multiple door opening angle positioning grooves 310 are arranged at intervals. The door opening angle positioning groove 310 is a taper groove, and the limiting push head 230 is provided with a transition bevel on the left and right sides. The purpose of the door opening angle positioning groove 310 is to provide positioning for fixing the door opening angle. In the design of the door structure, several preset opening angles of the door are designed. When the limiting push head 230 is clamped into the door opening angle positioning groove 310, it means that the door is opened to one of the preset opening angles. In the embodiment, two door opening angle positioning grooves 310 are provided, which correspond to the fully open and half open door opening angles, respectively. The door opening angle positioning groove 310 is arranged as a taper groove, and is matched with the transition bevel arranged on the left and right sides of the limiting push head 230, so that the limiting push head 230 can be more smoothly separated from the door opening angle positioning groove 310.

[0027] In a further scheme, one end of the limiting arm 300 is fixedly connected with an elastic buffer block 320, and the side of the elastic buffer block 320 away from the limiting arm 300 is fixedly connected with a mounting portion 330. The mounting portion 330 is provided with a positioning mounting hole, and is used to be rotationally connected with the vehicle body. The elastic buffer block 320 can provide buffering when the door is rotated to the maximum opening angle, so as to avoid problems such as bending of the limiting arm 300 caused by excessive force.

[0028] The working principle of the embodiment is as follows:

[0029] The vehicle body camera 500 and the vehicle body ranging radar 600 continuously perceive the obstacles around the vehicle. The vehicle domain controller 400 receives the obstacle information provided by the vehicle body camera 500 and the vehicle body ranging radar 600, and sends a signal to the damping driver 240 to control the damping driver 240 to adjust the damping value of the piston rod. In this way, the elasticity of the elastic push block unit 200 can be changed, and the force required for opening the door can be changed. When there is an obstacle outside the door, the damping value of the piston rod is increased, so that the force required for opening the door is increased. In this way, the purpose of reminding the operator is achieved.

[0030] In the embodiment 2, the structure of the elastic push block unit 200 is shown in the attached Figure 5 On the basis of the embodiment 1, the number of the elastic push block units 200 is increased to two, and the two elastic push block units 200 are symmetrically arranged on the upper and lower sides of the limiting arm 300. Compared with the structure of bearing force on one side, the structure of bearing force on both sides of the limiting arm 300 can make the limiting arm 300 more stable during movement, and the process of opening the door is more smooth.

[0031] In the description of the utility model, it needs to be understood that the directions such as '' front, back, up, down, left, right'', '' horizontal, vertical, perpendicular, horizontal'' and '' top, bottom'' and so on indicated direction or position relation is usually based on the direction or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, under the condition of not making the opposite statement, these direction words do not indicate and imply that the device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore can not be understood as the limitation of the protection scope of the utility model: the direction word '' inside, outside'' refers to the inside and outside relative to the contour of each component itself.

[0032] The above is only the preferred embodiment of the utility model, and any skilled person in the art can modify the utility model by using the above-mentioned technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement according to the technical solution of the utility model is within the scope of protection required by the utility model.
