Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Without loss of generality, the present embodiment uses the cover body 20 shown in the figures and adapted to the access opening 101 of the dashboard body 10 as a description main body, and explains the structural scheme of the access cover provided by the present embodiment in detail. It should be understood that the shape of the instrument panel and cover, as well as the specific dimensions of the access opening, do not constitute a substantial limitation on the access cover structure claimed herein.

Referring to fig. 1, there is shown an assembly view of the access cover structure according to the present embodiment.

The cover body 20 of the access cover structure is in the same shape as the access opening 101 of the instrument panel body 10, and the cover body 20 at the interface is preferably flush with the outer surface of the instrument panel body 10, so as to obtain good appearance experience. In the scheme, a bolt lock body adaptive pair 30 is arranged between the cover body 20 and the instrument board body 10 so as to realize the detachable connection of the cover body 20 relative to the body.

As shown, five sets of the deadbolt lock body adapter pairs 30 are provided along the mounting plane of the cover 20 to achieve a secure connection. In fact, for the access cover under a specific use situation, the setting number of the bolt lock body adaptation pairs 30 can be selected according to factors such as actual size, use frequency and cover body material; for example, a small-sized cover body can be reliably connected only by using two sets of the bolt lock body adapting pairs 30; for a cover with a large size, the pair of bolt lock body adapters 30 may be specifically configured as three, four or other plural sets.

Referring to fig. 2 and 3 together, fig. 2 is a sectional view taken along a-a of fig. 1, and fig. 3 is a sectional view taken along B-B of fig. 1.

The bolt 1 is fixedly connected with the cover 20, and the lock body 2 is used for fixedly connecting the body 10. As shown in fig. 2, the lock body 2 has a lock body cavity enclosed by an elastic outer wall 21 and capable of accommodating the bolt 1, and the insertion end of the bolt 1 is inserted into the lock body cavity and acts on the elastic outer wall 21 to deform, so as to form a clamping and locking state therebetween. That is to say, when the equipment under the effect that spring bolt 1 inserted the end, this lock body chamber is propped open, is in chucking locking state until spring bolt 1 and lock body 2 laminate completely, has simple structure, the reliable characteristics of installation. When needing to be dismantled, otherwise the operation can, the dismouting power is moderate, and it is comparatively convenient to operate. In addition, other tools are not needed in the operation process, the cost is low, and the whole structure does not occupy extra space.

In this scheme, lock body 2 is the working of plastics with spring bolt 1, and material cost is lower. For example, but not limited to, the bolt 1 material may be POM and the lock body 2 material may be PA 66. In order to further improve the connection reliability, the insertion end of the bolt 1 is preferably approximately in a drop shape, that is, the section of the insertion end is gradually changed in a drop shape; in this way, the adapted resilient outer wall 21 may form an adapted drop-shaped lock chamber, thereby providing further restraint in the direction of removal of the cover 20, and thereby improving the reliability of the connection therebetween.

In addition, the scheme preferably adopts detachable connection between the bolt 1 and the cover body 20 and between the lock body 2 and the body 10, so as to conveniently realize the assembly of the bolt and lock body adapting pair 30 and improve the assembly manufacturability of the access cover structure in the embodiment. Of course, the detachable connection can be realized by adopting different structural forms, and preferably, the detachable connection is in a clamping type.

Specifically, the adaptation side surface of lid 20 has spring bolt joint interface 201 and the spring bolt accommodation space 202 that communicates this spring bolt joint interface 201, and correspondingly, the installation end of spring bolt 1 has elasticity pothook 11, and the minimum dimension of spring bolt joint interface 201 is less than the size of elasticity pothook 11 under the normality, and compression deformation's elasticity pothook 11 gets into spring bolt accommodation space 202 through spring bolt joint interface 201 to resume deformation elasticity pothook 11 and arrange spring bolt accommodation space 202 in, form and to dismantle between spring bolt 1 and the lid 20 and be connected.

Here, the two elastic hooks 11 are symmetrically arranged relative to the clamping direction, so that an operator can complete the assembling pre-compression of the two elastic hooks 11 by one hand, the insertion operation can be further quickly carried out, and the assembling work efficiency is improved.

In addition, as shown in fig. 2 and 3, the cross section of the hook 12 gradually increases from the inside to the outside. Correspondingly, the lock tongue joint interface 201 is a taper hole with a small inside and a big outside, so that good insertion guide can be obtained, and insertion operation is further facilitated.

Specifically, the adaptation side surface of body 10 has lock body joint interface 102 and the lock body accommodation space 103 of intercommunication lock body joint interface 102, and the peripheral surface of lock body 2 has joint recess 22, and this joint recess 22 is used for the body 10 looks adaptation of lock body joint interface 102 position department, and during the equipment, lock body 2 makes deformation slightly and can clamp with lock body joint interface 102, forms the lock body 2 and is connected with dismantling of body 10.

Except aforementioned access cover structure, the utility model also provides an automobile is provided with the aforementioned access cover structure with access hole 101 adaptation to the instrument board that has access hole 101. It should be noted that the vehicle may be an SUV or other vehicle type, and other functions of the chassis, the frame, the power system, the electric control system, and the like of the vehicle constitute non-core points of the invention, and those skilled in the art can implement the functions by using the prior art, so details are not described herein.

In addition, the access cover structure provided by the embodiment is not limited to be used for automobile products, and can also be applied to other equipment or devices which need to be disassembled and assembled for maintenance. In addition, the bolt 1 and the lock body 2 of the scheme can adopt the detachable fixed connection mode, namely, the bolt 1 and the cover body 20 and the lock body 2 and the body 10 are respectively detachably connected; in fact, an integral molding process may also be adopted, and the bolt 1 and the cover 20, and the lock body 2 and the body 10 are respectively formed by integral injection molding, as long as the core points of the application are all within the scope of the application.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
