Description

Technical Field

[0001] This utility model relates to the field of automotive rotary knob screen technology, and in particular to a waterproof structure for automotive rotary knob screens. Background Technology

[0002] The in-vehicle rotary screen allows for quick menu selection and function switching by rotating and pressing a knob in a fixed position in the vehicle, eliminating the need for cumbersome touch operations on the screen. This facilitates "blind operation" for the driver while driving, improving driving safety.

[0003] In actual use, some behaviors of the driver, such as drinking water in the car or opening the sunroof and it suddenly raining, can easily cause water to enter at the connection between the front screen and the rear screen. This makes it necessary for the in-vehicle rotary screen to have a certain degree of waterproof function at the connection between the front screen and the rear screen. Utility Model Content

[0004] The main purpose of this utility model is to provide an embedded tuning meter that can effectively solve the waterproofing problem of vehicle-mounted rotary screens in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waterproof structure for a vehicle-mounted rotary screen, comprising a screen body, the screen body comprising a front screen and a rear cover, the front screen and the rear cover being fixed by screws, an annular groove being provided on the end face of the rear cover where it fits with the front screen, the bottom of the annular groove being arc-shaped, a stepped groove being provided inside the annular groove, a waterproof block being provided on the rear cover, the waterproof block being placed in the stepped groove and the end face of the waterproof block being flush with the end face of the rear cover, and a waterproof adhesive being provided on the contact end face of the front screen and the rear cover.

[0006] Further details: The end faces of the waterproof blocks are all coated with waterproof adhesive.

[0007] Further configuration: The screen body is provided with an arc-shaped groove located at the junction of the front screen and the rear cover.

[0008] Further configuration: The back cover is provided with a U-shaped partition strip, and the back cover is filled with a U-shaped partition ring, which is attached to the partition strip.

[0009] Further configuration: The other end of the partition ring that is in contact with the partition strip is provided with an arc-shaped protrusion, which is in contact with the arc-shaped groove.

[0010] Further configuration: The partition strip is higher than the joint between the front screen and the back cover.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The system employs a screw connection method, achieving a rigid seal through screw compression. Then, the application of waterproof adhesive one and waterproof adhesive two, combined with the screw locking mechanism, further enhances the sealing effect through adhesion and compression. The interplay of the arc-shaped protrusion and arc-shaped groove forms a second layer of primary protection, thus ensuring the waterproof capability of the vehicle's rotary knob screen. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the overall structure of the vehicle-mounted rotary knob screen of this utility model.

[0014] Figure 2 This is a schematic diagram of the back cover structure of this utility model;

[0015] Figure 3 This is a schematic diagram of the internal structure of the screen body of this utility model. Detailed Implementation

[0016] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] 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.

[0018] The screen body 101 includes a front screen 201 and a rear cover 301. The front screen 201 and the rear cover 301 are locked together by screws 102, ensuring that the front screen 201 and the rear cover 301 can be locked together. An annular groove 303 is provided on the contact end surface of the rear cover 301, and the bottom of the annular groove 303 is set in an arc shape. Through the setting of the stepped groove 302, the waterproof block 401 cannot directly contact the bottom of the annular groove 303. The waterproof block 401 itself is made of rubber and has a certain deformation ability during installation. When installed in the annular groove 303, it can squeeze out the internal air, forming a slight negative pressure to attract the waterproof block 401 and ensure the installation stability of the waterproof block 401. Waterproof adhesive one (not shown in the figure) is applied to the contact end surface of the front screen 201 and the rear cover 301, and waterproof adhesive two 402 is applied to the waterproof block 401. Waterproof adhesive one (not shown in the figure) Both waterproof adhesive 1 (not shown in the diagram) and waterproof adhesive 2 (402) are made of silicone rubber. When screw 102 is tightened, waterproof adhesive 1 (not shown in the diagram) and waterproof adhesive 2 (403) are compressed. Combined with the deformability of waterproof block 401, this increases the sealing performance, forming a relatively tight first layer of waterproofing. Furthermore, the partition strip 501 inside the back cover 301, and the partition ring 601, made of rubber, with an arc-shaped protrusion 602 on one side, further enhance this sealing. In conjunction with the arc-shaped groove 103, an arc-shaped fit is formed, further closing the joint between the front screen 201 and the rear cover 301, and further sealing the rear cover 301 and the front screen 201. The partition strip 501 is higher than the connecting end face of the front screen 201 and the rear cover 301, so that during installation, the partition ring 601 can fit with the partition strip 501 to form a support, ensuring the fitting effect of the arc-shaped protrusion 602 and the arc-shaped groove 103, and further ensuring the overall sealing performance.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
