Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of electronic components, in particular to a heat dissipation structure of a relay. Background Art

[0002] A relay is an electrical control device. When the change in input quantity (excitation quantity) reaches the specified requirement, it causes a predetermined step change in the controlled quantity in the electrical output circuit. It has an interactive relationship between the control system (also called the input circuit) and the controlled system (also called the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

[0003] In the current market, heat dissipation mechanisms are generally not provided for relays. Usually, the entire circuit controlled by the relay is heat-dissipated, and the relay is also heat-dissipated at the same time.

[0004] Cooling the entire circuit controlled by the relay and cooling the relay at the same time will result in poor heat dissipation of the relay. Poor heat dissipation will lead to poor electromagnetic effect of the relay, thereby causing poor control effect of the relay. Utility Model Content

[0005] The purpose of the utility model is to provide a heat dissipation structure of a relay to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation structure of a relay, comprising: a mounting plate, the interior of the mounting plate is fixedly connected to the side of a rotating motor, the output end of the rotating motor is fixedly connected to one end of an L-shaped plate, the interior of the L-shaped plate is fixedly connected to one end of a bracket, the other end of the bracket is fixedly connected to the side of a mounting seat, the bottom side of the mounting seat is fixedly connected to the side of a heat dissipation motor, the output end of the heat dissipation motor is fixedly connected to the axis of a fan blade, the bottom side of the mounting plate is fixedly connected to the top side of a base, the top side of the base is fixedly connected to the bottom side of a side plate, the side of the side plate is fixedly connected to one end of a support frame, the other end of the support frame is fixedly connected to one side of a relay body, and a cleaning mechanism is arranged inside the mounting plate, and the cleaning mechanism comprises:

[0007] A return spring, one end of which is fixedly connected to the top side of the dustproof net, and a through slot is formed below the dustproof net;

[0008] A convex block, the end of which is fixedly connected to the outer wall of the L-shaped plate.

[0009] Preferably, the top side of the dustproof net is fixedly connected to one end of the gain spring, and the other end of the gain spring is fixedly connected to the inside of the side plate, so that the resetting effect of the dustproof net is better.

[0010] Preferably, the end of the protrusion is configured to be hemispherical so that the protrusion will not scratch the edge bottom of the dustproof net.

[0011] Preferably, the number of the brackets is set to two groups, and the two groups of brackets are symmetrically distributed on both sides of the mounting seat, so that the brackets have a better supporting effect on the mounting seat.

[0012] Preferably, the width of the through slot should be set to allow the protrusion to pass through so that the movement of the protrusion is not hindered.

[0013] Compared with the prior art, the utility model provides a heat dissipation structure of a relay, which has the following beneficial effects:

[0014] 1. The heat dissipation structure of the relay can start the rotating motor to make the L-shaped plate rotate around the relay body when in use. At the same time, the fan blades will dissipate the heat of the relay body, so that the heat is evenly distributed around the relay body, avoiding the problem that the electromagnetic effect of the relay body will deteriorate due to poor heat dissipation, thereby causing the control effect of the relay body to deteriorate.

[0015] 2. The heat dissipation structure of the relay, when in use, when the L-shaped plate rotates, it will drive the dust net to vibrate, avoiding the problem of poor heat dissipation effect caused by dust accumulation on the dust net, and making the heat dissipation effect of the relay body better.

DETAILED DESCRIPTION

[0020] like Figure 1-3As shown, the utility model provides a technical solution: a heat dissipation structure of a relay, comprising: a mounting plate 1, the interior of the mounting plate 1 is fixedly connected to the side of a rotating motor 2, the output end of the rotating motor 2 is fixedly connected to one end of an L-shaped plate 3, the interior of the L-shaped plate 3 is fixedly connected to one end of a bracket 8, the other end of the bracket 8 is fixedly connected to the side of a mounting seat 7, the bottom side of the mounting seat 7 is fixedly connected to the side of a heat dissipation motor 6, the output end of the heat dissipation motor 6 is fixedly connected to the axis of a fan blade 5, the bottom side of the mounting plate 1 is fixedly connected to the top side of a base 4, the top side of the base 4 is fixedly connected to the bottom side of a side plate 10, the side of the side plate 10 is fixedly connected to one end of a support frame 11, the other end of the support frame 11 is fixedly connected to one side of a relay body 12, and a cleaning mechanism 9 is arranged inside the mounting plate 1, and the cleaning mechanism 9 comprises: Reset spring 901, protrusion 904, one end of the reset spring 901 is fixedly connected to the top side of the dustproof net 902, a through groove 903 is opened at the bottom of the dustproof net 902, and the end of the protrusion 904 is fixedly connected to the outer wall of the L-shaped plate 3. When in use, the heat dissipation motor 6 is started to rotate the fan blade 5 to blow the cold air around the relay body 12 to the relay body 12, so that the temperature of the relay body 12 is reduced. At this time, the rotating motor 2 is started to drive the L-shaped plate 3 to rotate, so that the surrounding of the relay body 12 is blown by the cold air. When the protrusion 904 passes through the through groove 903, it will squeeze the dustproof net 902 to move upward, and at the same time make the reset spring 901 contract. When the protrusion 904 leaves the through groove 903, the position of the dustproof net 902 is reset under the action of the reset spring 901.

[0021] In addition, in order to achieve a better resetting effect for the dustproof net 902, the top side of the dustproof net 902 is fixedly connected to one end of the gain spring 905, and the other end of the gain spring 905 is fixedly connected to the inside of the side plate 10. In order to prevent the protrusion 904 from scratching the bottom of the dustproof net 902, the end of the protrusion 904 is set to a hemispherical shape. In order to achieve a better supporting effect of the mounting seat 7, the number of brackets 8 is set to two groups, and the two groups of brackets 8 are symmetrically distributed on both sides of the mounting seat 7. In order to ensure that the movement of the protrusion 904 is not hindered, the width of the through groove 903 should be set to allow the protrusion 904 to pass through. In order to prevent the vibration frequency of the dustproof net 902 from being too large, the speed of the rotating motor 2 is set to a lower speed.

[0022] Working principle: When in use, start the heat dissipation motor 6 to rotate the fan blades 5, and blow the cold air around the relay body 12 to the relay body 12, so that the temperature of the relay body 12 is reduced. At this time, start the rotating motor 2, so that the rotating motor 2 drives the L-shaped plate 3 to rotate, so that the surrounding of the relay body 12 is blown by cold air. When the protrusion 904 passes through the through groove 903, it will squeeze the dust net 902 to move upward, and at the same time make the reset spring 901 contract. When the protrusion 904 leaves the through groove 903, under the action of the reset spring 901, the position of the dust net 902 is reset.

[0023] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
