[0001] The utility model relates to the field of remote controls, and particularly relates to a fall-proof remote control. Background Art

[0002] A remote control is a wireless transmitting device specifically designed to remotely control various mechanical equipment, electronic devices, or household appliances, etc. It uses different signal transmission methods such as radio waves or infrared rays to send the user's instructions in the form of wireless signals, thereby achieving precise operation of the controlled object. This device is widely used in televisions, air conditioners, audio systems, and many other household and industrial equipment, greatly improving the convenience and comfort of people operating these devices. Through simple button operations, users can easily adjust the settings of the equipment, switch channels, adjust the volume, etc., without directly contacting the equipment itself, thus avoiding the inconvenience of frequent getting up or walking.

[0003] Existing remote controls can already meet the basic needs of users in terms of functions. However, in pursuit of lightness and portability, remote controls generally use lightweight materials such as plastic as the shell. This choice has its advantages, but when facing external impacts such as collisions or accidental drops, the shell of the remote control is easily damaged. Especially the four corners of the remote control are most vulnerable to impacts, resulting in damage to the remote control and at the same time causing damage or malfunction of the internal circuit board or buttons, thereby affecting the normal use of the remote control. Therefore, the utility model proposes a fall-proof remote control. Summary of the Invention

[0004] The utility model provides a fall-proof remote control, which solves the problem that the remote control is easily damaged when colliding or accidentally dropping by providing protective blocks on the outer side of the shell.

[0005] The purpose of the utility model is achieved in the following way:

[0006] A fall-proof remote control includes a shell, a circuit board, and buttons. Protective blocks are symmetrically installed on the outer side of the shell. The protective blocks and the shell are respectively provided with pins and slots for mutual cooperation, and elastic limiting arms are symmetrically arranged on both sides of the pin.

[0007] Further, the shell includes a combinable upper cover and a base. A buckle is provided at the lower end of the upper cover, and a slot for cooperating with the buckle is provided on the base.

[0008] Further, positioning pins are provided inside the shell, and positioning holes for cooperating with the positioning pins are provided on the circuit board.

[0009] Further, a hollow layer is provided inside the protective block, and several support columns are provided inside the hollow layer.

[0010] Furthermore, a rechargeable battery is installed inside the housing, and charging contacts for cooperating with the battery are provided on the outer side of the housing.

[0011] Furthermore, the charging contacts are electrically connected to one end of the battery through elastic metal sheets.

[0012] Furthermore, a silica gel sealing pad is sleeved between the housing and the button.

[0013] Advantages of the present utility model: Through the cooperation between the elastic limiting arms on both sides of the plug pin and the slots, the protection block is firmly fixed on the outer side of the remote control housing. When the remote control falls or collides, the protection block can absorb part of the impact force, reduce the damage to the housing and internal components, avoid the damage of the remote control caused by accidental dropping, and thus improve the service life and durability of the remote control.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments.

[0023] In this embodiment, with reference toFigures 1-7 , a kind of anti - fall remote control implemented specifically, includes a housing 1, a circuit board 2 and buttons 3. Protective blocks 4 are symmetrically installed on the outer side of the housing 1. The protective blocks 4 and the housing 1 are respectively provided with a plug pin 5 and a slot 6 for mutual cooperation. Elastic limiting arms 7 are symmetrically arranged on both sides of the plug pin 5. The protective block 4 is made of a material with a buffering effect such as silica gel or rubber, so that the protective block 4 can absorb the impact force when the remote control accidentally falls, thereby protecting the internal circuit board 2 and buttons 3 from damage. By aligning the plug pin 5 of the protective block 4 with the slot 6 on the housing 1 and squeezing, the elastic limiting arms 7 are temporarily deformed, so that the plug pin 5 can smoothly pass through the narrow part of the slot 6. Once the plug pin 5 is completely inserted into the slot 6, the elastic limiting arms 7 will return to their original state and tightly clamp on both sides of the slot 6, ensuring the tight combination of the protective block 4 and the housing 1. This design not only improves the convenience of assembly, but also during use, even when subjected to external force impact, the elastic limiting arms 7 can effectively prevent the protective block 4 from falling off, ensuring the durability of the protective effect. Thus, the overall durability and reliability of the remote control are improved.

[0024] Furthermore, the housing 1 includes a combinable upper cover 8 and a base 9. A buckle 10 is provided at the lower end of the upper cover 8, and the base 9 is provided with a slot 11 for cooperating with the buckle 10. By aligning the buckle 10 of the upper cover 8 with the slot 11 of the base 9 and pressing for cooperation, the upper cover 8 and the base 9 are stably connected. This makes the assembly of the housing 1 very convenient.

[0025] Furthermore, a positioning pin 12 is provided inside the housing 1, and the circuit board 2 is provided with a positioning hole 13 for cooperating with the positioning pin 12. Through the cooperation of the positioning pin 12 and the positioning hole 13, the circuit board 2 can be accurately positioned inside the housing 1, ensuring the tight fit between the circuit board 2 and the housing 1, thereby avoiding the displacement or damage of the circuit board 2 when the remote control is impacted. During the assembly process, just align the positioning hole 13 with the positioning pin 12 on the housing 1 and insert it, then the circuit board 2 can be fixed in the predetermined position, corresponding one - to - one with the contacts on the buttons 3, thus ensuring the accuracy of the button 3 operation and the stability of the circuit.

[0026] Furthermore, a hollow layer 14 is provided inside the protective block 4, and several support columns 15 are provided inside the hollow layer 14. Through the cooperation of the hollow layer 14 and the support columns 15, when being impacted, the protective block 4 can be slightly deformed and effectively disperse the impact force received through the support columns 15, further improving the protective effect. The support columns 15 and the protective block 4 are integrally formed, making the overall structure more robust and durable. The design of the hollow layer 14 not only reduces the weight of the protective block 4, but also increases its buffering performance, so that when the remote control accidentally falls, it can better protect the internal components.

[0027] Further, a rechargeable battery 16 is installed inside the housing 1, and charging contacts 17 that cooperate with the battery 16 are provided on the outer side of the housing 1. By connecting the charging contacts 17 to an external charger, the battery 16 inside the remote control can be conveniently charged, reducing environmental pollution without the need to frequently replace the battery 16, and improving the convenience and environmental friendliness of use. And by contacting the outside through the contacts, the installation gap is reduced, thereby enhancing the waterproof performance of the remote control.

[0028] Further, the charging contacts 17 are electrically connected to one end of the battery 16 through elastic metal sheets 18. The elastic metal sheets 18 have certain elasticity and conductivity, ensuring that the contact between the charging contacts 17 and the battery 16 remains stably connected after the remote control is vibrated or dropped. It avoids the problem of poor contact caused by vibration, bumping, etc., thus ensuring the continuity and reliability of the charging process.

[0029] Further, a silica gel sealing pad 19 is sleeved between the housing 1 and the buttons 3. The silica gel sealing pad 19 wraps all the buttons 3 and is firmly pressed by the cooperation of the upper cover 8 and the lower cover, thereby forming a sealed environment. The silica gel sealing pad 19 has good waterproof performance, preventing foreign matters such as water droplets and dust from entering the inside of the remote control, ensuring that the remote control can work normally in various environments. At the same time, the silica gel sealing pad 19 also has certain elasticity and friction, making the buttons 3 have a good feel during operation while reducing the occurrence of hand slipping, improving the comfort and accuracy of operation.

[0030] The beneficial effects of the present utility model: Through the cooperation of the elastic limiting arms 7 on both sides of the plug pin 5 and the slot 6, the protective block 4 is firmly fixed on the outer side of the remote control housing 1. When the remote control falls or is bumped, the protective block 4 can absorb part of the impact force, reducing the damage to the housing 1 and internal components, avoiding the damage of the remote control caused by accidental dropping, and thus improving the service life and durability of the remote control.

[0031] The above is only a preferred embodiment of the present utility model, and it does not impose any form of limitation on the present utility model.
