DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0025] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0026] This embodiment mainly describes the waterproof structure of the scooter instrument panel, which is as follows:

[0027] The instrument panels currently on the market have a structure in which grooves are cut and sealing rings / gaskets are placed, and then the grooves are tightened by a cover body. As a result, there are few sealing surfaces. If local aging problems occur, water leakage will occur, and in severe cases, the circuit board and display screen in the instrument panel will be damaged.

[0028] Main program :

[0029] In view of the above problems, this embodiment provides a scooter instrument panel waterproof structure, refer to the attached Figure 1-4, including a bottom shell 10 and a transparent cover 20, the bottom shell 10 is provided with a circle of annular slots 103 along the edge, a circle of annular sealing grooves 104 are provided along the bottom of the slots 103, a sealing ring 30 is provided in the sealing groove 104, the sealing ring 30 includes a lower sealing body 302 extending into the sealing groove 104 and an upper sealing body 301 located at the bottom of the slots 103 on both sides of the sealing groove 104, and the cover 20 is provided with a circle of lower edges 201 extending into the slots 103 and fixed in the slots 103, after the lower edges 201 are inserted, the upper sealing body 301 is squeezed and abutted against the bottom of the slots 103, and at the same time, the lower sealing body 302 is squeezed and deformed to form three abutting surfaces on the bottom wall of the sealing groove 104 and the two side walls of the sealing groove 104. When the sealing ring 30 in this scheme is pressed, it forms a multi-position seal by deformation, and even if it is partially aged, it will maintain a strong sealing performance, thereby protecting the internal circuit board and display screen.

[0030] In order to allow the sealing ring 30 to have sufficient deformation space, the depth of the sealing groove 104 is smaller than the height of the lower sealing body 302, and the width of the sealing groove 104 is larger than the width of the lower sealing body 302. During installation, when the upper sealing body 301 has not been pressed, the bottom of the lower sealing body 302 has already abutted against the bottom of the sealing groove 104. When the cover body 20 is further pressed down and tightened, the upper sealing body 301 is pressed against the bottom of the slot 103, and the lower sealing body 302 is deformed to form three abutment surfaces with the bottom wall of the sealing groove 104 and the two side walls of the sealing groove 104.

[0031] Sealing ring part :

[0032] like Figure 3 As shown, the lower sealing body 302 is a hollow structure, and its side wall is provided with ribs 3021. The hollow structure can expand to both sides to form more contact surfaces after being squeezed, and the ribs 3021 are annular structures. When the lower sealing body 302 is deformed, the ribs 3021 and the side walls of the sealing groove 104 are tightly fitted to form a seal.

[0033] Preferably, the cross section of the lower sealing body 302 is wide in the middle and narrow at both ends, and after being compressed, the two sides of the middle deform and abut against the two side walls of the sealing groove 104. After being squeezed, the middle of the structure expands outward and abuts against the side walls of the sealing groove 104 to form a seal.

[0034] like Figure 3 As shown, a downwardly convex spherical body 3012 is provided in the middle of the bottom side of the upper sealing body 301, and a circle of arc surface 105 that matches the bottom surface of the spherical body 3012 is provided on the top side of the sealing groove 104. After pressing, the spherical surface of the upper sealing body 301 is tightly against the arc surface 105.

[0035] like Figure 3As shown, a sheet body 3011 is provided on the top of the spherical body 3012, and the two sides of the sheet body 3011 extend horizontally and abut against the bottom of the slot 103 after installation. When pressed, the sheet body 3011 abuts against the bottom of the slot 103, specifically, against the bottom of the slot 103 on both sides of the sealing slot 104. This structure forms multiple contact surfaces at the top, including both flat contact surfaces and curved contact surfaces, further improving the sealing effect.

[0036] Cover fixing part :

[0037] Preferably, the lower edge 201 of the cover 20 is interference-fitted with the side wall of the slot 103. The interference-fit structure is applicable to more shapes, and the bottom shell 10 and the cover 20 can be fixed by pressing as long as they have a pluggable structure.

[0038] like Figure 1 As shown, a locking hole 101 is provided on the side wall of the slot 103, and the locking hole 101 is opened at the side wall of the slot 103. A locking hook 40 is provided on the cover 20 to match the locking hole 101. After the cover is closed, the locking hook 40 is buckled into the locking hole 101. The locking structure is used to lock the cover 20 to prevent it from loosening due to bumps.

[0039] like Figure 1 As shown, a strip-shaped slide groove 102 is provided on the side wall of the bottom shell 10 above the locking hole 101, and when the cover body 20 is closed, the lock hook 40 slides from the slide groove 102 into the locking hole 101. The slide groove 102 is used for the sliding of the lock hook 40.

[0040] like Figure 1 As shown, the lock hook 40 is a U-shaped hook with elasticity. When the cover is opened, the lock hook 40 can be squeezed inward to make the lock hook 40 disengage from the locking hole 101. The lock hook 40 has an elastic force to flip outward. When installed, it is pressed inward to be located in the slide groove 102. When the cover body 20 is completely closed, it flips outward at a certain angle under the action of its own elastic force and buckles in the locking hole 101 to achieve locking. When unlocking, just press the lock hook 40 inward. Preferably, a protrusion that can extend into the locking hole 101 can be provided on the lock hook 40 to cooperate with the locking hole 101 for locking.

[0041] The above is a detailed introduction to the titles provided by the utility model. Specific examples are used in this article to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified. These improvements and modifications also fall within the scope of protection of the claims of the utility model.
