Description

Technical Field

[0001] The invention belongs to the technical field of key automobile parts and relates to a sliding cover structure which can be locked when opened and can be automatically closed when pressed. Background Art

[0002] At present, the common sliding cover structure is to apply pulling / pushing force by the hand so that the sliding cover is opened or closed under the force of the hand. However, there are strict requirements on the operating space of the hand at the handle pushed and pulled by the fingers. If the space is too small, the sliding cover cannot be opened to the predetermined position as required, and cannot be closed normally. Summary of the invention

[0003] The purpose of the present invention is to provide a sliding cover structure which can be locked when opened and can be automatically closed when pressed.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A sliding cover structure which can be locked when opened and can be automatically closed when pressed, comprises a sliding cover bracket, a sliding cover body which can slide back and forth in a straight line on the sliding cover bracket, a rebound member arranged between the sliding cover bracket and the sliding cover body, and a locking and unlocking member installed on the sliding cover bracket, wherein the sliding cover body is also provided with a boss which can be inserted into the locking and unlocking member, and when the boss is opened to the maximum along the sliding direction of the sliding cover body when the locking and unlocking member is opened, the boss is locked by the locking and unlocking member, and the sliding cover body is locked; when the boss continues to move in the opening direction, the boss is unlocked in the locking and unlocking member, and under the action of the rebound member, the boss automatically closes as the sliding cover body rebounds.

[0006] Furthermore, the locking and unlocking member includes a locking and unlocking body rotatably mounted on the sliding cover bracket, and a locking and unlocking track is also provided on the locking and unlocking body for the boss to slide into, and when the boss slides in the locking and unlocking track, the sliding cover body is locked and closed on the sliding cover bracket in sequence.

[0007] Furthermore, the locking and unlocking track includes a guide groove that faces the sliding direction of the sliding cover body and guides the boss to slide in or out, and a locking and unlocking groove connected to the guide groove. A heart-shaped locking and unlocking block is also provided in the middle position of the locking and unlocking groove, so that a working slide with a locking position and an unlocking position is formed between the locking and unlocking groove and the locking and unlocking block.

[0008] Further preferably, an inner concave point of the outer contour of the locking and unlocking block is set as the locking position, and the inner concave point and the inclined area beside it that is inclined toward the inner concave point are defined as the locking area, and the working slideway is divided into an opening locking section, a pressing and unlocking section and an automatic sliding-out section that are connected in sequence along the sliding track of the boss, wherein the front end of the opening locking section is connected to the guide slide groove, the end of the pressing and unlocking section is set as the unlocking position, and the end of the automatic sliding-out section is also connected to the guide slide groove,

[0009] When the line connecting the end of the opening locking section and the rotation center of the locking and unlocking member is parallel to the sliding direction of the sliding cover body, the projection of the end of the opening locking section in the sliding direction of the sliding cover body falls into the locking area.

[0010] When the line connecting the locking position and the rotation center of the locking and unlocking member is parallel to the sliding direction of the sliding cover body, the projection of the locking position along the sliding direction of the sliding cover body falls on the front section of the pressing and closing section.

[0011] When the line connecting the unlocking position and the rotation center of the locking unlocking member is parallel to the sliding direction of the sliding cover body, the projection of the unlocking position along the sliding direction of the sliding cover body falls within the automatic sliding-out section outside the locking area. More preferably, the end of the unlocking section has an inward concave design, so that when the boss slides to this position, there is an obvious sense of sinking, thereby indicating that it is in place.

[0012] More preferably, along the opening direction of the sliding cover body, the push-to-close section is arranged obliquely at the front end of the locking position, and the corner where the push-to-close section is connected to the automatic sliding-out section forms the unlocking position.

[0013] Further preferably, the two side walls at the opening of the guide slide groove are inclined and spread outward.

[0014] Furthermore, the locking and unlocking body is rotatably mounted on the sliding cover bracket via a pin shaft.

[0015] Furthermore, limiting protrusions are symmetrically installed on both sides of the locking and unlocking body, and an arc-shaped limiting section with the rotation center of the locking and unlocking body as the center of the circle and into which the limiting protrusions can be inserted is also provided on the sliding cover bracket.

[0016] Furthermore, the resilient member is a coil spring.

[0017] Furthermore, a sliding cover handle is also processed on the sliding cover body.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) When the sliding cover body is opened to the maximum state, the sliding cover body is stable. The sliding cover body needs to be pressed in the sliding direction for a certain stroke before it is unlocked, so as to avoid the sliding cover body from shaking.

[0020] (2) When the sliding cover body is unlocked and rebounded, it only needs to be pushed a certain distance in the opening direction on the sliding cover body, and the sliding cover body will be unlocked and automatically rebound through the rebound member, thereby preventing the sliding cover body from being unable to close due to the lack of finger operating space at the sliding cover handle.

[0021] (3) The locking and unlocking body can be slightly rotated left and right, and can cooperate with the locking and unlocking groove processed on its surface to achieve a smooth transition from the locked position to the unlocked position. BRIEF DESCRIPTION OF THE DRAWINGS
