Description

Technical Field

[0001] This utility model relates to the field of automotive remote control technology, and in particular to a sealing device for the battery compartment of an automotive remote control. Background Technology

[0002] As automobiles become a crucial mode of transportation, their operating environments are facing increasingly stringent requirements. For remote controls, which are often exterior components, customers are demanding increasingly thinner and lighter designs while maintaining an IP57 waterproof rating and easy battery replacement.

[0003] Currently, OEMs are demanding increasingly thinner overall remote controls, without compromising waterproofing performance. To meet the IP57 waterproof rating and facilitate battery replacement, remote controls previously featured a separate battery cover. This increased the overall thickness of the remote control's CAS (Computer Interface) and resulted in a thicker design, contradicting OEMs' requirements for a slimmer remote control appearance.

[0004] For example, CN217455919U, published on September 20, 2022, discloses a car remote control. This car remote control includes a housing, a button panel disposed on the housing, and a silicone plate and circuit board disposed within the housing. The button panel, silicone plate, and circuit board are arranged in a corresponding stacked manner. The silicone plate has button posts corresponding to the buttons on the button panel and the buttons on the circuit board. The silicone plate also has multiple support posts corresponding to each button post. Both the button posts and support posts extend from the button panel to the circuit board. In the aforementioned remote control, the silicone plate is directly installed inside the housing, resulting in poor sealing performance for the entire remote control. Summary of the Invention

[0005] The purpose of this invention is to provide a sealing device for the battery compartment of a car remote control with better sealing performance. This invention uses ribs on the rear cover to compress silicone, thereby ensuring a stable seal between the outer cover and the rear cover, resulting in a better sealing effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a sealing device for a car remote control battery compartment, including an outer cover and a rear cover that are interlocked with each other, a circuit board is provided on the rear cover, a battery is provided between the circuit board and the outer cover, silicone is provided on the outer cover, the silicone is in contact with the battery and the rear cover, and a rib is provided on the rear cover that abuts against the silicone.

[0007] The outer cover has a first protrusion and a second protrusion, and there is a mounting groove between the first protrusion and the second protrusion. The silicone is disposed in the mounting groove. The first protrusion is close to the rib. The thickness of the silicone is greater than the height of the second protrusion. The height of the second protrusion is greater than the height of the first protrusion.

[0008] The rear cover has two raised ribs.

[0009] The rear cover is provided with a protrusion, and the outer cover is provided with a guide groove that engages with the protrusion.

[0010] The outer cover has a side edge, and the area between the side edge and the first protrusion is a guide groove.

[0011] The protrusion has an abutment surface that contacts the silicone, and the protruding rib is provided on the abutment surface.

[0012] The contact surface, silicone, and outer cover are arranged parallel to each other.

[0013] The beneficial effects of this utility model are:

[0014] Place the battery between the back covers, move the outer cover and the back cover to interlock. At this time, the silicone on the outer cover squeezes the battery and the back cover. The ribs on the back cover squeeze the silicone. The silicone deforms under pressure and comes into close contact with the ribs, thereby increasing the sealing performance of the silicone. The battery is sealed by a single silicone, thus reducing the overall thickness of the battery and making it more practical.

[0015] The thickness of the silicone is greater than the height of the second protrusion, and the height of the second protrusion is greater than the height of the first protrusion. This allows the silicone to move with the outer cover in the mounting groove until it comes into contact with the back cover, thereby deforming the silicone in the mounting groove. Furthermore, the protrusions on the back cover further deform the silicone, resulting in a better sealing effect of the silicone on the battery.

[0016] The back cover has a protrusion, and the outer cover has a guide groove that engages with the protrusion. The protrusion and the guide groove work together to guide the connection between the back cover and the outer cover, thus achieving a convenient connection between the outer cover and the back cover.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figure 1-4 As shown, the car remote control battery compartment sealing device includes an outer cover 1 and a rear cover 2 that are interlocked. A circuit board 3 is provided on the rear cover 2, and a battery 4 is provided between the circuit board 3 and the outer cover 1. A silicone 5 is provided on the outer cover 1, and the silicone 5 contacts the battery 4 and the rear cover 2. A rib 6 is provided on the rear cover 2 that abuts against the silicone 5. Specifically, the battery 4 is located in the middle of the rear cover 2. In this embodiment, there are two silicone 5s, which are arranged side by side, and the maximum span between the two silicone 5s is greater than the width of the battery 4.

[0025] The battery 4 is placed between the back cover 2. The outer cover 1 and the back cover 2 are moved to engage with each other. At this time, the silicone 5 on the outer cover 1 squeezes the battery 4 and the back cover 2. The rib 6 on the back cover 2 squeezes the silicone 5. The silicone 5 deforms under pressure and comes into close contact with the rib 6, thereby increasing the sealing performance of the silicone 5. The battery is sealed by a silicone 5, thereby reducing the overall thickness of the battery and making it more practical.

[0026] The outer cover 1 has a first protrusion 11 and a second protrusion 12. The first protrusion 11 and the second protrusion 12 form a mounting groove 9. The silicone 5 is placed in the mounting groove 9. The first protrusion 11 is close to the rib 6. The thickness of the silicone 5 is greater than the height of the second protrusion 12. The height of the second protrusion 12 is greater than the height of the first protrusion 11. This allows the silicone 5 to move with the outer cover 1 in the mounting groove 9 until it abuts against the rear cover 2. This allows the silicone 5 to deform in the mounting groove 9. Furthermore, the rib 6 on the rear cover 2 causes the silicone 5 to deform further, resulting in a better sealing effect of the silicone 5 on the battery.

[0027] The back cover 2 has two raised ribs 6, which increases the sealing performance when the back cover 2 comes into contact with the silicone 5.

[0028] The rear cover 2 is provided with a protrusion 7, and the outer cover 1 is provided with a guide groove 8 that engages with the protrusion 7. The protrusion 7 and the guide groove 8 work together to guide the connection between the rear cover 2 and the outer cover 1, thereby achieving a convenient connection between the outer cover 1 and the rear cover 2.

[0029] The outer cover 1 is provided with a side plate 10, and the area between the side plate 10 and the first protrusion 11 is a guide groove 8, which facilitates the movement of the protrusion 7 between the side plate 10 and the first protrusion 11. Specifically, the side plate 10 is provided at the edge of the outer cover 1.

[0030] The protruding bracket 7 is provided with an abutting surface 13 that contacts the silicone 5, and the protruding rib 6 is provided on the abutting surface 13. The abutting surface 13 contacts the silicone 5 to perform the extrusion deformation of the silicone 5.

[0031] Specifically, the contact surface 13, silicone 5, and outer cover 1 are arranged in parallel to each other, thereby ensuring that the silicone 5 is stably deformed when the outer cover 1 and the rear cover 2 assembly are squeezed.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
