[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: an infrared remote control electromagnetic lock, which includes a housing 1 and a mounting plate 2. The housing 1 is installed on the door body and serves as the external framework of the entire infrared remote control electromagnetic lock, providing a space for the installation and protection of various internal components. The mounting plate 2 is installed on the door frame and is used to close the door body. A controller 6 is provided on the inner wall of the upper part of the housing 1 to control the operation of the entire electromagnetic lock, receive and process signals from the infrared receiver 7, and command relevant components to perform unlocking or locking actions. This technology is prior art, so it will not be elaborated here. An infrared receiver 7 is provided on the inner wall of the right side of the housing 1 to receive signals from the infrared remote control and transmit them to the controller 6 to initiate corresponding operations. This technology is prior art, so it will not be elaborated here. A buckle 3 is provided on the left side of the mounting plate 2 to further improve the locking strength of the door body. A slot is formed through the lower part of the mounting plate 2 for the lock tongue 44 to insert into.

[0031] Furthermore, a strengthening component is provided on the inner wall of the housing 1. The strengthening component includes a moving block 41 made of silicon steel, which slides on the inner wall of the housing 1. By moving left and right, it drives the lock tongue 44 to achieve unlocking and locking actions. The outer side of the moving block 41 is slidably connected to the inner wall of the housing 1. The left side of the moving block 41 is elastically connected to the housing 1 through a return spring 42, providing a restoring elastic force for the moving block 41 to return to its initial position after the unlocking action is completed. A roller is provided at the bottom end of the moving block 41, and the outer side of the roller is slidably connected to the inner wall of the housing 1, which can reduce the friction with the housing 1. A lock tongue 44 is fixedly connected to the right side of the moving block 41, and the outer side of the lock tongue 44 slides on the inner wall of the housing 1, extending out of or retracting into the housing 1, and cooperating with the slot to achieve the closing and opening of the door body.

[0032] Referring to Figure 2 and Figure 3 , a protective component is provided at the top end of the moving block 41 to reduce the impact force received by the moving block 41 during movement. A slider 45 is provided on the right side of the protective component. The left side of the bottom end of the slider 45 is set as an inclined surface, and the inclined surface at the left side of its bottom end interacts with the inclined surface at the top right end of the extrusion block 53. When being squeezed, it drives the sliding rod to move upward. The slider 45 and the extrusion block 53 are always in a fitting state. A sliding rod is fixedly connected to the top end of the slider 45, connecting the slider 45 and the limiting block 48 and sliding on the inner wall of the housing 1 to transmit motion. The outer side of the upper part of the sliding rod is slidably connected to the inner wall of the housing 1. A fixing plate 47 is fixedly connected to the outer wall of the sliding rod near the upper side of the slider 45, cooperating with the first compression spring 46 to provide a buffering and restoring force for the movement of the sliding rod and the slider 45. The outer side of the fixing plate 47 slides on the inner wall of the housing 1.

[0033] Further, the fixing plate 47 is elastically connected to the housing 1 through the first compression spring 46 to provide an elastic restoring force for the slider 45 and the fixing plate 47. The top end of the sliding rod is fixedly connected with a limiting block 48, which is used to insert into the inner wall of the buckle 3 sliding on the inner wall of the card slot, so as to strengthen the fixing strength of the mounting plate 2. A card slot is opened on the front side of the housing 1 near the limiting block 48. When the door is closed, the buckle 3 will be inserted into the card slot. A buffer pad is arranged on the left side of the electromagnet 43. The buffer pad is made of rubber. Its main function is to reduce the impact and wear generated when the moving block 41 directly collides with the electromagnet 43. Rubber has certain elasticity and buffering performance, which can reduce the noise during collision, protect relevant components, extend the service life of the equipment, and make the operation of the equipment more stable and reliable.

[0034] Refer to Figure 2 and Figure 3 , the protection component includes a mounting block 51, which provides a mounting basis for the moving rod 52 and the extrusion block 53. The bottom end of the mounting block 51 is fixedly connected to the top end of the moving block 41. The rear side of the inner wall of the mounting block 51 is slidably connected with the moving rod 52, which is connected to the extrusion block 53 and slides on the inner wall of the mounting block 51. The right side of the moving rod 52 is fixedly connected with the extrusion block 53. Through its inclined surface contacting the inclined surface of the slider 45, the force is transmitted to drive the slider 45, the sliding rod and the limiting block 48 to move upward. The top right side of the extrusion block 53 is set as an inclined surface, and the inclined surface at the top right side of the extrusion block 53 slides on the inclined surface at the left bottom of the slider 45.

[0035] Further, the moving rod 52 is elastically connected to the mounting block 51 through the second compression spring 54 to provide a restoring elastic force for the moving rod 52. At the same time, by compressing the second compression spring 54, the moving block 41 is protected, and the impact force generated between the moving block 41, the buffer pad, the gasket 55 and the electromagnet 43 is further absorbed and dispersed. A gasket 55 is arranged on the right side of the mounting block 51, which plays a role in buffering and protecting the left side of the extrusion block 53.

[0036] Working principle: When in use, when it is necessary to close and lock the door, push the door body to make it close to the door frame. At this time, use the infrared remote control to send a locking signal. The infrared receiver 7 receives this signal and transmits it to the controller 6. The buckle 3 on the mounting plate 2 is inserted into the card slot on the front side of the housing 1. Subsequently, the controller 6 controls the electromagnet 43 to be energized to generate magnetic force, attracting the moving block 41 to move to the right. The rubber buffer pad on the left side of the electromagnet 43 plays a buffering role, reducing the impact and wear generated by the direct collision between the moving block 41 and the electromagnet 43, reducing noise, protecting relevant components, ensuring that the electromagnetic lock runs more smoothly and reliably, and extending the service life of the equipment. The moving block 41 drives the lock tongue 44 to extend to the right and insert into the slot to complete the locking of the door body.

[0037] During the process of the moving block 41 moving rightward, while the inclined surface at the right top of the extrusion block 53 provided at the top of the moving block 41 contacts the inclined surface at the left bottom of the slider 45, it drives the moving rod 52 to slide on the inner wall of the mounting block 51 and squeezes the second compression spring 54 to protect the movement of the moving block 41.

[0038] At this time, the extrusion block 53 pushes the slider 45 to move upward, and the slider 45 drives the sliding rod to slide upward on the inner wall of the housing 1. The fixing plate 47 on the sliding rod compresses the first compression spring 46. When the limiting block 48 at the top of the sliding rod is inserted into the inner wall of the buckle 3, the fixing strength of the mounting plate 2 is further enhanced, and the locking stability is improved.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
