Abstract
Description
Technical Field
[0001] This utility model belongs to the automotive field and relates to a small door that is particularly suitable for refueling and charging various motor vehicles such as buses and commercial vehicles. Background Technology
[0002] With the upgrading of emissions standards for traditional gasoline vehicles and the popularization of electric buses, the demand for vehicle access doors has gradually expanded from the original refueling access door to urea filling access doors, mechanical handle opening and closing access doors, and charging access doors. The aesthetics, ease of use, and feel of opening and closing access doors are becoming increasingly important to users.
[0003] Traditional small doors have handles or locks, which disrupt the overall design of the vehicle; moreover, they lack damping when opening and closing, resulting in wobbling when opening and rattling when closing, and have a poor feel. Utility Model Content
[0004] The technical problem to be solved by this utility model is: how to solve the problem of small door shaking when opening and vibrating when closing, and to provide a small door with switch damping.
[0005] To solve the above problems, this utility model is achieved through the following technical solution:
[0006] A small door with switch damping includes a door panel, a small door stop is provided on the door panel, a small door panel is installed on the small door stop, the small door panel is installed on the small door stop by a hinge, and a damper is connected to the hinge.
[0007] The small door panel is bonded or welded to the hinge, and the damper is connected to the hinge's pivot.
[0008] The hatch panel and the small door stop are bonded or welded together.
[0009] A push-button lock is installed on the stop of the small door, and a lock-button counters are installed on the small door panel. The push-button lock and the lock-button counters are configured accordingly.
[0010] A proximity switch is installed on the small door stop.
[0011] Compared with the prior art, this utility model has the following advantages: it eliminates the need for a handle or lock; at the same time, it adds damping during the opening and closing process, so that the speed of the small door is slowly reduced when it is about to open or close, thus solving the problems of shaking when opening and rattling when closing, and also improving the aesthetics of the small door design.

[0012] Figure 1 This is a structural diagram of the back of the small door;
[0013] Figure 2 This is a front view of the small door. Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] like Figure 1 , Figure 2 As shown, a small door with switch damping includes a door panel 2, a small door stop 6 is provided on the door panel 2, a small door panel 1 is installed on the small door stop 6, the small door panel 1 is installed on the small door stop 6 by a hinge 5, and a damper 4 is connected to the hinge 5.
[0017] Furthermore, the small door panel 1 is bonded or welded to the hinge 5 and rotates around the pivot of the hinge 5 to open or close. The damper 4 is connected to the pivot of the hinge 5 to provide damping when the small door panel 1 rotates, reducing the rotation speed when the small door panel 1 is close or open, thus solving the problem of the small door panel 1 shaking when opening and making a banging sound when closing.
[0018] Furthermore, the hatch panel 2 and the small door stop 6 are bonded or welded together.
[0019] Furthermore, the door panel 2 is a door panel or a body panel.
[0020] Furthermore, a push-button locking device 3 is provided on the small door stop 6, and a locking device counter 7 is provided on the small door panel 1. The push-button locking device 3 and the locking device counter 7 are correspondingly arranged. The push-button locking device 3 is provided with an ejection mechanism, which has two positions. When closed, the small door panel 1 is pressed to lock the locking device counter 7 in conjunction with the ejection mechanism on the push-button locking device 3. When closed, the hatch panel 2 is flush with the small door panel 1. When the small door panel 1 is pressed again, the ejection mechanism on the push-button locking device 3 pushes the small door panel 1 open with a gap, at which point the small door panel 1 can be opened by hand. The push-button locking device 3 works alternately in locking and opening modes.
[0021] In this utility model, a push-button type locking device 3 is used instead of a handle or lock, which has locking and unlocking functions, eliminates the handle or vehicle lock, improves the overall appearance and enhances aesthetics.
[0022] Furthermore, a proximity switch 8 is installed on the small door stop 6. The proximity switch 8 is connected to the vehicle controller. In this way, the central unlocking / locking function of the push-type lock 3 can be realized through the vehicle control program, saving layout space and realizing central unlocking / locking.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
