Description

Technical Field

[0001] The utility model relates to the technical field of television remote controllers, in particular to a crosstalk-proof television remote controller. Background Art

[0002] A TV remote control is a wireless transmitting device that encodes key information through modern digital coding technology and emits light waves through infrared diodes. The infrared receiver of the receiver converts the received infrared signal into an electrical signal, which is decoded by the processor and demodulated to produce the corresponding instructions to control the set-top box and other devices to complete the required operations.

[0003] The TV remote control is mainly composed of a microprocessor chip that forms the remote control signal, a crystal oscillator, an amplifying transistor, an infrared light-emitting diode and a keyboard matrix. Inside the remote control, there is a chip similar to a computer processor, which is responsible for converting the user's key press actions into machine-recognizable binary coded information. After modulation and encoding, this information is sent out in the form of infrared light waves through an infrared emitting diode. In general, the TV remote control is an important tool for TV operation. It allows users to control the various functions of the TV more conveniently and enhance the viewing experience.

[0004] When using the TV remote control, you need to aim the infrared transmitter of the remote control at the infrared receiver of the TV to ensure normal signal transmission, and then issue corresponding commands through the buttons on the TV remote control to control various functions of the TV.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A TV remote control for preventing crosstalk, such as Figure 1-3 As shown, it includes a protective shell 1, a groove 2 is provided on the top of the protective shell 1, and a remote control body 3 is movably connected in the groove 2, which is beneficial to protecting the remote control body 3 through the protective shell 1, and at the same time, a group of placement grooves 10 are provided on the top of the protective shell 1, and a movable block 11 is movably connected in each placement groove 10, and the position of the movable block 11 can be limited by the placement groove 10, and a fixed block 14 is fixedly connected to the adjacent side of a group of movable blocks 11, and the fixed block 14 is located on the top of the remote control body 3. Therefore, after the position of the movable block 11 is fixed in the placement groove 10, the position of the fixed block 14 can be fixed synchronously, so that the position of the remote control body 3 can be fixed by the fixed block 14.

[0028] Fixed grooves 12 are provided on both sides of the movable block 11, and elastic blocks 13 matching the fixed grooves 12 are movably connected in the fixed grooves 12, so that the elastic blocks 13 can move in the fixed grooves 12, and the elastic blocks 13 are fixedly connected to the corresponding two sides of the protective shell 1, so that the friction between the movable block 11 and the protective shell 1 can be increased through the fixed grooves 12 and the elastic blocks 13, and the position of the movable block 11 can be fixed by the friction between the two. A rubber layer is provided at the connection between the movable block 11 and the protective shell 1 to increase the friction between the movable block 11 and the protective shell 1. When the external force is small, the movable block 11 cannot be removed from the top of the protective shell 1, so that the position of the movable block 11 can be better fixed.

[0029] Then, a cavity 18 is provided in the protective shell 1, and a water bag 4 is connected in the cavity 18, so that the water bag 4 can expand in the cavity 18. A first hole 5 is provided at the bottom of the protective shell 1, and the water bag 4 is located in the first hole 5. When the water bag 4 expands, the water bag 4 in the first hole 5 can expand outward, thereby contacting the bottom of the remote control body 3, which is beneficial to the heat generated when the remote control body 3 is used. It can be absorbed by the water bag 4 at the bottom, thereby reducing the heat in the remote control body 3 and avoiding crosstalk in the remote control body 3 caused by high temperature. A connecting tube 15 is movably penetrated on one side of the protective shell 1, and one end of the connecting tube 15 is connected to the water bag 4. Water can be transported into the water bag 4 through the connecting tube 15, and the water in the water bag 4 can also be discharged through the connecting tube 15. A rubber plug 16 that fits the connecting tube 15 is movably connected in the connecting tube 15, so that the connecting tube 15 can be blocked by the rubber plug 16.

[0030] A second hole 8 is further provided at one end of the protective shell 1, and an infrared transmitting port 9 is provided at one end of the remote control body 3, and the position and size of the infrared transmitting port 9 match those of the second hole 8, which is beneficial for placing the remote control body 3 inside the groove 2 so that the infrared transmitting port 9 can overlap with the second hole 8, so that the infrared transmitting port 9 can be connected to the infrared receiver of the TV through the second hole 8, thereby better controlling various functions of the TV.

[0031] Wherein, card slots 6 are provided on both sides of the protective shell 1, and the water bag 4 is located in the card slots 6. The position of the card slots 6 is higher than the top of the remote control body 3, which is beneficial to the water bag 4 in the card slots 6 to expand outward when the water source is transported into the water bag 4. Since the position of the card slots 6 is higher than the position of the remote control body 3, the water bag 4 in the card slots 6 can generate a downward force on the top of the remote control body 3, so that the water bag 4 can play an auxiliary fixing role on the top of the remote control body 3.

[0032] At the same time, anti-collision strips 7 are bonded to the four corners of the protective shell 1, which is beneficial for the anti-collision strips 7 to play a buffering role when the protective shell 1 is bumped, so as to better protect the remote control body 3. A number of protrusions 17 are provided on both sides of the protective shell 1, and the protrusions 17 can increase the friction between the user and the protective shell 1, thereby increasing the stability of the protective shell 1 when held.
