Description

Technical Field

[0001] This invention relates to the field of infrared chip technology, specifically to infrared emitting chips. Background Technology

[0002] Infrared remote control is a widely used communication and control method. Due to its advantages such as simple structure, low power consumption, strong anti-interference ability, high reliability, and low cost, it is widely used in home appliances, industrial control, and intelligent instrument systems. A general infrared remote control system consists of two main parts: a transmitter and a receiver, using dedicated integrated circuit chips for encoding / decoding to perform control operations.

[0003] Infrared emitting chips are typically installed on a circuit board inside the remote control device. The contacts of the infrared emitting chip are soldered to the solder points on the circuit board. However, the installation of existing infrared emitting chips is very troublesome. Since there is no mutual restraint structure between the infrared emitting chip and the circuit board, the operator needs to hold the infrared emitting chip in one hand and a soldering gun in the other. The operator aligns the infrared emitting chip with the solder points on the circuit board and then solders it. However, because the infrared emitting chip itself is not restrained, it is easy for it to shift during the soldering process, making the operation very difficult. Summary of the Invention

[0004] The purpose of this invention is to provide an infrared emitting chip to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an infrared emitting chip, comprising a circuit board and an infrared emitting chip body, wherein two limiting strips are symmetrically arranged at the end of the infrared emitting chip body, one of which has a limiting hole, and multiple contacts are symmetrically arranged on the side of the infrared emitting chip body; two mounting plates are symmetrically arranged on the circuit board, the infrared emitting chip body is located between the two mounting plates, and fixing brackets are symmetrically arranged on the side of the mounting plates, with both ends of the fixing brackets rotatably connected to the two mounting plates via rotating shafts; the mounting plates have limiting grooves adapted to the limiting strips, and the limiting strips are inserted into the limiting grooves to limit the infrared emitting chip body; one of the mounting plates is fixedly connected to... The mounting plate has a fixed groove and a movable groove. The movable groove contains a first spring, a movable plate, and a rod corresponding to a limiting hole. The movable plate is fixedly connected to the rod, and one end of the rod passes through the mounting plate and is connected to a lever. The other end of the rod passes through the mounting plate and is inserted into the limiting hole to fix the infrared emitting chip body. The fixed groove contains a winding wheel, a connecting plate, a positioning rod, and a second spring. The winding wheel is rotatably connected to the fixed groove via a rotating shaft. The connecting plate is located on both sides of the winding wheel and is fixedly connected to the fixed groove. A positioning rod is fixedly connected to the connecting plate, and a sliding plate is slidably connected to the positioning rod. The circuit board in the figure is only a small part of the circuit board and is not the actual object.

[0006] Preferably, the circuit board has a plurality of solder points corresponding to the contacts evenly arranged on the side of the mounting plate. The contacts of the infrared emitting chip body are in contact with the corresponding solder points, and the contacts and solder points are welded together by using a soldering gun.

[0007] Preferably, the first spring is sleeved on the insert rod, and the two ends of the first spring are respectively connected to the movable plate and the movable groove. After the limiting strip of the infrared emitting chip body is inserted into the limiting groove, the first spring is used to insert the insert rod into the limiting hole to limit and fix the infrared emitting chip body.

[0008] Preferably, the second spring is sleeved on the positioning rod, and both ends of the second spring are respectively connected to the slide plate and the connecting plate. Both the first spring and the second spring can be replaced with other elastic components.

[0009] Preferably, the winding wheel is provided with two pull ropes corresponding to the skateboard. The two pull ropes pass through the connecting plate and are connected to the corresponding skateboard. By rotating the winding wheel to wind up the pull ropes, the skateboard can be moved by pulling the pull ropes.

[0010] Preferably, the end of the fixing frame is provided with a limiting sleeve, and the limiting sleeve has a first fixing hole and a second fixing hole, both of which are used to limit the fixing frame.

[0011] Preferably, a fixing plug is fixedly connected to the skateboard. The fixing plug passes through the fixing slot and is inserted into the first fixing hole to restrict the fixing frame. When the fixing plug is inserted into the first fixing hole, the fixing frame is closed and pressed on the contact foot. When the fixing plug is inserted into the second fixing hole, the fixing frame is in the upright and open state.

[0012] Preferably, the end of the take-up reel passes through the fixing groove and is connected to a knob, which has raised anti-slip stripes, mainly for the convenience of the operator to rotate the take-up reel.

[0013] Preferably, the fixing frame is equipped with a welding frame, which covers the contact feet and is mainly used to assist the worker in welding work, reducing the welding range to the normal range.

[0014] Preferably, the end of the limiting strip is provided with an inclined surface, which can be used to push the insertion rod upward when the limiting strip is inserted into the limiting groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention inserts the limiting strip of the infrared emitting chip body laterally into the limiting groove. When the limiting hole moves to the position of the insertion rod, the first spring can be used to push the insertion rod back and insert it into the limiting hole to fix it. Then, the winding wheel is rotated to wind up the pull rope. The pull rope then pulls the slide plate to pull the fixing plug into the fixing groove. Then, the fixing frame is pushed down to press the fixing frame onto the contact foot. At this time, the winding wheel can be rotated in the opposite direction, and the second spring can be used to push the slide plate back and insert the fixing plug into the first fixing hole to fix the fixing frame. The infrared emitting chip body is fixed a second time. Then, the operator can use a welding gun to weld the contact foot. It is very convenient. By fixing and limiting the infrared emitting chip body first and then welding it, the stability of the infrared emitting chip body is effectively improved. Attached Figure Description

[0026] Please see Figure 1-6This invention provides a technical solution: an infrared emitting chip, comprising a circuit board 1 and an infrared emitting chip body 2. The infrared emitting chip body 2 has two symmetrically arranged limiting strips 202 at its end, one of which has a limiting hole 2021. The infrared emitting chip body 2 also has multiple symmetrically arranged contact feet 201 on its side. Two mounting plates 3 are symmetrically arranged on the circuit board 1, with the infrared emitting chip body 2 located between the two mounting plates 3. Fixing brackets 5 are symmetrically arranged on the side of each mounting plate 3, with both ends of the fixing brackets 5 rotatably connected to the two mounting plates 3 via rotating shafts. Each mounting plate 3 has a limiting groove 301 adapted to the limiting strips 202, into which the limiting strips 202 are inserted to limit the infrared emitting chip body 2. One of the mounting plates 3 has a fixedly connected fixing groove 4 and a movable groove 302. The movable slot 302 is equipped with a first spring 306, a movable plate 303, and a rod 304 corresponding to the limiting hole 2021. The movable plate 303 is fixedly connected to the rod 304, and one end of the rod 304 passes through the mounting plate 3 and is connected to a lever 305. The other end of the rod 304 passes through the mounting plate 3 and is inserted into the limiting hole 2021 to fix the infrared emitting chip body 2. The fixed slot 4 is equipped with a winding wheel 405, a connecting plate 401, a positioning rod 402, and a second spring 404. The winding wheel 405 is rotatably connected to the fixed slot 4 through a rotating shaft. The connecting plate 401 is located on both sides of the winding wheel 405 and is fixedly connected to the fixed slot 4. The positioning rod 402 is fixedly connected to the connecting plate 401, and the sliding plate 403 is slidably connected to the positioning rod 402. The circuit board 1 in the figure is only a small part of the circuit board 1 and is not the actual object.

[0027] Furthermore, the circuit board 1 has a plurality of solder points 101 corresponding to the contacts 201 evenly arranged on the side of the mounting plate 3. The contacts 201 of the infrared emitting chip body 2 are in contact with the corresponding solder points 101, and the contacts 201 and solder points 101 are welded together by using a soldering gun.

[0028] Furthermore, the first spring 306 is sleeved on the insertion rod 304, and the two ends of the first spring 306 are respectively connected to the movable plate 303 and the movable groove 302. After the limiting strip 202 of the infrared emitting chip body 2 is inserted into the limiting groove 301, the first spring 306 is used to insert the insertion rod 304 into the limiting hole 2021 to limit and fix the infrared emitting chip body 2.

[0029] Furthermore, the second spring 404 is sleeved on the positioning rod 402, and the two ends of the second spring 404 are respectively connected to the slide plate 403 and the connecting plate 401. The first spring 306 and the second spring 404 can be replaced with other elastic components.

[0030] Furthermore, the take-up reel 405 is provided with two pull ropes 4051 corresponding to the slide plate 403. The two pull ropes 4051 pass through the connecting plate 401 and are connected to the corresponding slide plate 403. By rotating the take-up reel 405 to wind up the pull ropes 4051, the slide plate 403 can be moved by pulling the pull ropes 4051.

[0031] Furthermore, the end of the fixing frame 5 is provided with a limiting sleeve 502, and the limiting sleeve 502 is provided with a first fixing hole 5021 and a second fixing hole 5022. Both the first fixing hole 5021 and the second fixing hole 5022 are used to limit the fixing frame 5.

[0032] Furthermore, a fixing plug 4031 is fixedly connected to the slide plate 403. The fixing plug 4031 passes through the fixing groove 4 and is inserted into the first fixing socket 5021 to restrict the fixing frame 5. When the fixing plug 4031 is inserted into the first fixing socket 5021, the fixing frame 5 is closed and pressed on the contact foot 201. When the fixing plug 4031 is inserted into the second fixing socket 5022, the fixing frame 5 is in the upright open state.

[0033] Furthermore, the end of the take-up reel 405 passes through the fixing groove 4 and is connected to a knob 4052. The knob 4052 is provided with raised anti-slip stripes, which are mainly used to facilitate the operator to rotate the take-up reel 405.

[0034] Furthermore, the fixing frame 5 is provided with a welding frame 501, which covers the contact foot 201 and is mainly used to assist the worker in welding work and reduce the welding range to the normal range.

[0035] Furthermore, the end of the limiting strip 202 is provided with an inclined surface 2022, which can be used to push the insertion rod 304 upward when the limiting strip 202 is inserted into the limiting groove 301.

[0036] Working principle: In use, simply insert the limiting strip 202 of the infrared emitting chip body 2 horizontally into the limiting groove 301. When the inclined surface 2022 on the limiting strip 202 contacts the insertion rod 304, it will push the insertion rod 304 upward, causing the insertion rod 304 to drive the movable plate 303 upward. This causes the movable plate 303 to press the first spring 306, causing the first spring 306 to deform and contract. When the limiting hole 2021 on the limiting strip 202 moves to the position of the insertion rod 304, the first spring 306 will rebound due to the lack of pressure, inserting the insertion rod 304 into the limiting hole 2021 to fix the infrared emitting chip body 2. Then, rotate the knob 4052, causing the knob 4052 to drive the winding wheel 405 to rotate, causing the winding wheel 405 to wind up the pull rope 4051. Then, use the pull rope 4051 to pull the slide plate 403, causing the slide plate 403 to push the second spring 404 upward. The pressure causes the second spring 404 to deform and contract, causing the slide plate 403 to drive the fixing plug 4031. When the fixing plug 4031 is pulled into the fixing groove 4, the fixing frame 5 is then pushed downwards, pressing the fixing frame 5 onto the contact foot 201, so that the contact foot 201 contacts the solder point 101. At this time, the take-up wheel 405 can be rotated in the opposite direction, causing the second spring 404 to push the slide plate 403 back. When the fixing plug 4031 on the slide plate 403 is inserted into the first fixing hole 5021, the fixing frame 5 is fixed, and the infrared emitting chip body 2 is fixed a second time. Then, the operator can use a welding gun to weld the contact foot 201, which is very convenient. By fixing and restricting the infrared emitting chip body 2 first, and then welding it, the stability of the infrared emitting chip body 2 is effectively improved. The welding frame 501 set during welding can restrict the welding position, which improves the practicality of the invention.
