Technical Field

[0001] This invention relates to the field of electromagnetic relay manufacturing, and more specifically to an electromagnetic relay. Background Technology

[0002] An electromagnetic relay is an electronic control device with a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is commonly used in automatic control circuits, essentially acting as an "automatic switch" that uses a smaller current and lower voltage to control a larger current and higher voltage. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching. Electromagnetic relays are widely used in aviation, aerospace, shipbuilding, and home appliances, primarily performing functions such as signal transmission, execution control, and system power distribution. They are one of the key electronic components in various systems. However, the electromagnetic coil inside the electromagnetic relay is prone to overheating and burnout, causing the entire electromagnetic relay to fail and even affecting the operation of the entire circuit. To solve this problem, timely replacement of the electromagnetic relay is necessary; therefore, an electromagnetic relay is designed to achieve the aforementioned functions. Summary of the Invention

[0003] The present invention provides an electromagnetic relay, the purpose of which is to enable quick replacement of damaged electromagnetic relay parts.

[0006] A sliding box is fixedly connected to the base plate, and four racks are slidably connected inside the sliding box. The sliding box has four slits, and each rack can mesh with the corresponding gear II from the slit. A top plate is fixedly connected to the top of the sliding box.

[0007] A motor housing is fixedly connected to the bottom of the base plate, a motor plate is fixedly connected to the bottom of the motor housing, and a motor is fixedly connected to the motor plate; a bracket is fixedly connected inside the motor housing, the output shaft of the motor passes through the bracket, and the output shaft of the motor is fixedly connected to the rotating shaft I.

The two connecting rods are slidably connected in the corresponding sliding groove. A mounting plate I is fixedly connected to the bottom of the two connecting rods. A rotating shaft II is fixedly connected to the bottom of the mounting plate I. A mounting plate II is fixedly connected to the bottom of the rotating shaft II.

Detailed Implementation

[0031] See Figure 1-5 A schematic diagram of an embodiment of the present invention, in which gear I 104 drives four gears II 105 to rotate, is shown. Further,

[0032] A rotating shaft I103 is rotatably connected to the base plate 102, and a gear I104 is fixedly connected to the rotating shaft I103; four gears II105 are rotatably connected to the base plate 102, and all four gears II105 are meshed with gears I104.

[0033] It can provide mounting positions for gear I 104 and four gears II 105; the rotating shaft I 103 can drive gear I 104 to rotate, and the rotation of gear I 104 can simultaneously drive the four gears II 105 to rotate, thereby driving the rack 107 installed in four directions to move.

[0034] See Figure 1-7 A schematic diagram of an embodiment in which gear II 105 drives rack 107 to slide according to the present invention is shown. Further,

[0035] A sliding box 106 is fixedly connected to the base plate 102, and four racks 107 are slidably connected inside the sliding box 106; at the same time, the sliding box 106 is provided with four slits, and each rack 107 can mesh with the corresponding gear II 105 from the slit; a top plate 101 is fixedly connected to the top of the sliding box 106.

[0036] The slide box 106 has four intersecting slide tracks inside, and a rack 107 is slidably connected in each slide track. The slide track can restrict the sliding of the rack 107, thereby ensuring that the rack 107 maintains linear motion. The four cuts provided in the slide box 106 can expose each rack 107, so that the rack 107 can mesh with the gear II 105 at the cuts, thereby causing the gear I 104 to rotate and drive the four gears II 105 to rotate, further driving the four racks 107 to slide simultaneously.

[0037] See Figure 1-9 A schematic diagram of an embodiment of the present invention, in which the motor 404 drives the gear I104 to rotate, is shown. Further,

[0038] A motor housing 401 is fixedly connected to the bottom of the base plate 102, a motor plate 402 is fixedly connected to the bottom of the motor housing 401, and a motor 404 is fixedly connected to the motor plate 402; a bracket 403 is fixedly connected inside the motor housing 401, the output shaft of the motor 404 passes through the bracket 403, and the output shaft of the motor 404 is fixedly connected to the rotating shaft I 103; at the same time, a spring I 405 is fixedly connected between the bracket 403 and the rotating shaft I 103.

[0039] The motor 404 is installed inside the motor housing 401, which protects the motor 404. The motor 404 drives the rotating shaft I 103 fixed on the output shaft to rotate, thereby driving the gear I 104 to rotate. This allows the motor 404 to simultaneously drive the four gears II 105 to rotate and the four racks 107 to slide. The bracket 403 stabilizes the output shaft of the motor 404 and the rotation of the rotating shaft I 103. The spring I 405 stores energy during the output of the motor 404, so that when the motor 404 is not working, the rotating shaft I 103 and the gear I 104 tend to rotate clockwise.

[0040] See Figure 1-10 A schematic diagram of an embodiment of mounting plate I 202 and mounting plate II 205 according to the present invention is shown, further,

[0041] The base plate 102 is provided with four sliding grooves. Two connecting rods 201 are fixedly connected to the bottom of each rack 107. The two connecting rods 201 are slidably connected in the corresponding sliding groove. A mounting plate I 202 is fixedly connected to the bottom of the two connecting rods 201. A rotating shaft II 203 is fixedly connected to the bottom of the mounting plate I 202. A mounting plate II 205 is fixedly connected to the bottom of the rotating shaft II 203. A hook plate 204 is rotatably connected to the rotating shaft II 203.

[0042] During the sliding process, the four racks 107 can drive the corresponding two connecting rods 201 to slide in the groove, thereby driving the corresponding mounting plate I 202 and mounting plate II 205 to move; the rotating shaft II 203 is used to connect the mounting plate I 202 and mounting plate II 205; the rotating shaft II 203 is used to install the hook plate 204, so that the hook plate 204 can rotate around the rotating shaft II 203, thereby hooking the groove 302 on the outside of the relay 301.

[0043] See Figure 1-11 This shows a schematic diagram of an embodiment in which the hook plate 204 is slidably connected within the slot according to the present invention. Further,

[0044] An inner frame 502 is fixedly connected to the bottom of the base plate 102. The side of the inner frame 502 is provided with a slot through which the hook plate 204 can pass. A torsion spring is fixedly connected between the mounting plate I 202, the mounting plate II 205 and the hook plate 204. The torsion spring can make the hook plate 204 have a tendency to rotate towards the inner frame 502. Limit buckles 206 are fixedly connected to the upper and lower sides of the hook plate 204 respectively.

[0045] Mounting plate I 202 and mounting plate II 205 are tightly attached to the outer side of the inner frame 502. The hook plate 204 can pass through and slide in the slot. The torsion spring is sleeved on the outer side of the rotating shaft II 203, which makes the hook plate 204 have a tendency to rotate inward, so that it can pass through the slot and hook into the groove 302 on the outside of the relay 301. Limiting buckles 206 are fixed to the upper and lower sides of the hook plate 204 respectively. The limiting buckles 206 can be tightly attached to the outer side of the slot, so that the hook plate 204 will not rotate excessively, and prevent the hook plate 204 from completely entering the inner frame 502, thereby hindering the movement of the relay 301.

[0046] See Figure 1-11 A schematic diagram of an embodiment in which the hook plate 204 and the relay 301 form a lock according to the present invention is shown. Further,

[0047] Four relays 301 are slidably connected between the inner frame 502 and the motor housing 401. Each relay 301 has a groove 302, which can lock with the hook plate 204. Each relay 301 has two electrode plates I 303 fixedly connected to the bottom.

[0048] Four relays 301 correspond to four hook plates 204 respectively, and the hook plates 204 drive the relays 301 to slide simultaneously, so that the four relays 301 can move in a counterclockwise direction. Taking the movement of the hook plate 204 and the relay 301 located on the rear side as an example, the hook plate 204 moves to the right under the drive of the rack 107, hooks the groove 302 and drives the relay 301 to move to the right, pushing the relay 301 to the right rear corner of the inner frame 502. At this time, the motor 404 works to drive the rack 107 and the hook plate 204 to the left, and the front end of the hook plate 204 can slide out of the groove 302 on the relay 301 and return to the initial position, and hook the groove 302 on the relay 301 located on the left rear. In the above way, the four hook plates 204 can drive the four relays 301 to achieve cyclic movement, preventing the relays 301 from being damaged when working for a long time, and thus replacing the damaged relays 301 in time.

[0049] See Figure 1-10 The diagram shows an embodiment in which the support plate 207 stabilizes the sliding of the mounting plate I 202 and the mounting plate II 205 according to the present invention. Further,

[0050] A box 501 is fixedly connected to the bottom of the base plate 102. A support plate 207 is fixedly connected between the mounting plate I 202 and the mounting plate II 205. The outer side of the support plate 207 is tightly attached to the inner side of the box 501.

[0051] The box 501 is located at the bottom of the entire invention and can support all the parts; at the same time, there is a gap between the inner frame 502 and the box 501, and the support plate 207 is slidably connected in the gap between the inner frame 502 and the box 501, thereby stabilizing the sliding of the mounting plate I 202 and the mounting plate II 205.

[0052] See Figure 1-12 A schematic diagram of an embodiment in which the electrode plate 503 and the relay 301 are connected according to the present invention is shown. Further,

[0053] An electrode plate 503 is fixedly connected to the bottom of the box 501. Two electrode pieces II 505 are fixedly connected to the top of the electrode plate 503, and two pins 504 are fixedly connected to the bottom of the electrode plate 503.

[0054] The electrode plate 503 is located at the left rear of the housing 501. The two electrode pieces II 505 fixed above the electrode plate 503 can be connected to the two electrode pieces I 303 on the relay 301 located above the electrode plate 503, so that the relay 301 located at the left rear can work. The two pins 504 fixed below the electrode plate 503 are used to connect the electrode plate 503 to the circuit, so that the relay 301 can work in the circuit.

[0055] See Figure 1-13 A schematic diagram of embodiments of skateboard I 506 and skateboard II 507 according to the present invention is shown, further,

[0056] An opening is provided at the right rear of the box body 501 and the inner frame 502; a spring II 508 is fixed between the support plate 207 located at the left rear and the box body 501; a sliding plate I 506 is fixed to the outside of the support plate 207 located at the right rear, and a sliding plate II 507 is fixed to the inside of the mounting plate I 202 and mounting plate II 205 located at the right rear.

[0057] Slide I 506 and slide II 507 can cover the openings on the right rear of the housing 501 and the inner frame 502 to protect the internal parts of the invention; the elastic force of spring II 508 can accelerate the support plate 207 on the left rear, so that the support plate 207 on the left rear can move quickly, thereby accelerating the movement of the hook plate 204 and the relay 301 in the four directions, and allowing the relay 301 on the left rear to slide out from the opening on the right rear of the housing 501 and the inner frame 502, thereby replacing the damaged relay 301.
