Description

Technical Field

[0001] This utility model relates to the technical field of advertising gates, specifically to an electric motor core for advertising gates. Background Technology

[0002] Most existing advertising gates consist of a left door frame post, a right door frame post, and an advertising gate body. One side of the advertising gate body is rotatably connected to the left door frame post, while the other side can be locked to the right door frame post. The right door frame post is usually equipped with a magnetic locking mechanism, and the advertising gate body can be locked to the magnetic locking mechanism or separated from the magnetic locking mechanism.

[0003] Existing advertising gates, because the gate body needs to be locked to the door frame posts, can only open in one direction, causing inconvenience for pedestrians. To solve this problem, a motor core for advertising gates disclosed in existing technology (Chinese patent application number CN201820750820.6, application date 2018-05-18) can be referenced. This motor core activates the locking mechanism and locks the motor when the outer side of the advertising gate is closed, thus locking the position of the advertising gate. Therefore, one door frame post can be reduced, and the magnetic locking mechanism can also be reduced, making the structure of the advertising gate simpler and reducing manufacturing costs. Furthermore, since no magnetic locking mechanism is used, there is no energy consumption from the magnetic locking mechanism, reducing energy consumption.

[0004] Although the aforementioned motor core for advertising gates can solve the problem of pedestrian access, it still has certain shortcomings in practice. When replacing the posters inside the advertising gate, it is necessary to disassemble and reassemble the motor core and the advertising gate, which makes subsequent replacement difficult.

[0005] Therefore, we proposed that the electric motor core used in advertising gates can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a motor core for advertising gates, so as to solve the problem mentioned in the background art that when the posters inside the advertising gates are replaced, the motor core needs to be disassembled and reassembled with the advertising gate, which is not conducive to the later replacement process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a motor core for an advertising gate, comprising a first column and a second column, the bottoms of which are fixed to the bottom surface. An advertising gate body is rotatably mounted on one side of the first column, and the advertising gate body achieves bidirectional rotation on the outside of the first column through a motor core assembly. The motor core assembly serves as a driving force to control the rotation direction and angle of the advertising gate body. An advertising frame is slidably mounted inside the advertising gate body, and a limiting mechanism is provided inside the advertising frame to limit the offset of the advertising inside the advertising frame. A magnetic locking mechanism is provided on the first column to cooperate with the advertising gate body, and the magnetic locking mechanism is used to lock and fix the advertising gate body after it has rotated to the correct position.

[0008] As a preferred technical solution of this application, the motor core assembly includes a motor core body installed inside the first column. The output end of the motor core body is fixedly connected to the bottom center of the rotating gear. A mating gear is meshed with the outer side of the rotating gear. The tops of both the rotating gear and the mating gear are rotatably disposed within a dustproof housing. A rotating shaft is fixedly attached to the bottom of the mating gear. The bottom of the rotating shaft is fixedly connected to one end of the advertising door. The magnetic locking mechanism includes a locking unit that cooperates with the rotating shaft. The locking unit is used to lock the rotating shaft when the advertising door rotates to a preset position.

[0009] As a preferred technical solution of this application, the magnetic locking mechanism includes an electromagnet and a magnetic block. The electromagnet is fixed to the inner side of the first column and corresponds to the position of the rotation axis. The magnetic block is fixed to the outer side of the rotation axis. When the advertising door rotates to the closed position, the electromagnet is energized to generate magnetic force and attracts the magnetic block, thereby locking the advertising door.

[0010] As a preferred technical solution of this application, the bottom outer side of the dustproof housing is installed on the top of the first column, and the first column and the second column have the same height.

[0011] As a preferred technical solution of this application, a number of connecting springs are fixed on one side of the advertising frame, and the other end of the connecting spring is fixed to the inner wall of the first column. A bonding block is fixed below the advertising frame near the connecting spring. When the advertising door is rotated to the maximum angle, the bonding block is bonded to the outer wall of the first column. The magnetic locking mechanism is linked with the bonding block. When the bonding block is bonded to the first column, the magnetic locking mechanism is in the unlocked state.

[0012] As a preferred technical solution of this application, the limiting mechanism includes a fixed rack fixed to the inner side of the advertising door, a drive gear meshing with the outer side of the fixed rack, a transmission gear fixed to the top shaft end of the drive gear, connecting racks meshing with both sides of the transmission gear, and the other end of the connecting rack fixed to one side of the bonding plate. The control module of the magnetic locking mechanism is electrically connected to the motor core assembly. When the limiting mechanism completes the advertising limiting, the control module triggers the magnetic locking mechanism to maintain the locked state.

[0013] As a preferred technical solution of this application, the moving directions of the bonding plates are arranged opposite to each other, and the bonding plates and connecting racks are fixed inside the advertising frame. The unlocking signal of the magnetic locking mechanism is triggered by the reverse drive command of the motor core assembly. When the motor core assembly receives the reverse rotation signal, the magnetic locking mechanism is de-energized and unlocked, and the advertising door can rotate in the reverse direction.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This advertising gate uses a motor core, which enables bidirectional rotation of the advertising gate body through the motor core assembly. Combined with a magnetic locking mechanism, it achieves precise locking, eliminating the need for traditional bidirectional columns and corresponding locks, simplifying the structure, reducing costs and energy consumption, and facilitating bidirectional pedestrian passage. The advertising frame is slidably set up and equipped with connecting springs and contact blocks. Combined with the rack and pinion linkage of the limiting mechanism, it can firmly clamp the advertisement to prevent displacement, and allows for easy removal and replacement of the advertisement without disassembling the core, simplifying later maintenance. The dustproof shell protects the transmission components, extending their service life. Overall, it combines practicality and economy, effectively solving the problem of disassembling and reassembling the core when replacing posters on existing advertising gates. Specific details are as follows:

[0015] 1. The magnetic locking mechanism is linked with the motor core assembly. The door is precisely locked by the attraction between the electromagnet and the magnetic block. The unlocking signal is directly triggered by the reverse drive command of the mechanism, which has a rapid response and stable locking state. Compared with the independent control mode of traditional magnetic locks, it reduces signal delay and improves the safety and reliability of door opening and closing.

[0016] 2. The connecting spring of the advertising frame works in conjunction with the bonding block to adaptively adjust its position during the rotation of the door. When the door rotates to its maximum angle, the bonding block is in contact with the column, which not only prevents the advertising frame from shaking excessively, but also provides stable support for the advertising frame. Combined with the two-way bonding plate of the limiting mechanism, the advertising fixation effect is further enhanced, ensuring that the advertising display is flat. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 The present invention provides the following technical solution: a motor core for advertising doors.

[0027] Example 1: To address the issue that replacing posters inside advertising gates currently requires disassembling the motor mechanism from the advertising gate, which hinders subsequent replacement processes, please refer to the attached... Figure 1 and attached Figure 4 -Appendix Figure 6An advertising frame 5 is slidably installed inside the advertising door 3. A limiting mechanism is provided inside the advertising frame 5 to restrict the offset of the advertisement inside the frame 5. Several sets of connecting springs 6 are fixed to one side of the advertising frame 5, and the other end of the connecting springs 6 is fixed to the inner wall of the first column 1. A bonding block 7 is fixed below the connecting springs 6 on the advertising frame 5. When the advertising door 3 rotates to its maximum angle, the bonding block 7 is bonded to the outer wall of the first column 1. A magnetic locking mechanism is linked to the bonding block 7. When the bonding block 7 is bonded to the first column 1, the magnetic locking mechanism is in the unlocked state. The limiting mechanism includes a fixed rack 8 fixed to the inner side of the advertising door 3. A drive gear 9 is meshed with the outer side of the fixed rack 8. A transmission gear 10 is fixed to the top shaft end of the moving gear 9. Connecting racks 11 are meshed on both the left and right sides of the transmission gear 10. The other end of the connecting rack 11 is fixed to one side of the bonding plate 12. The control module of the magnetic locking mechanism is electrically connected to the motor core assembly 4. When the limiting mechanism completes the advertising limit, the control module triggers the magnetic locking mechanism to maintain the locked state. The moving directions of the bonding plate 12 are set opposite to each other, and the bonding plate 12 and the connecting rack 11 are fixed inside the advertising frame 5. The unlocking signal of the magnetic locking mechanism is triggered by the reverse drive command of the motor core assembly 4. When the motor core assembly 4 receives the reverse rotation signal, the magnetic locking mechanism is de-energized and unlocked, and the advertising door 3 can rotate in the reverse direction.

[0028] When the poster inside the advertising gate 3 needs to be replaced, the motor core assembly 4 receives a reverse drive command, triggering the magnetic locking mechanism to de-energize and unlock. The advertising gate 3 can then rotate in the reverse direction to its maximum angle. At this time, the bonding block 7 below the advertising frame 5 is bonded to the outer wall of the first column 1, and the magnetic locking mechanism remains unlocked. Since the advertising frame 5 is slidably installed inside the advertising gate 3 and connected to the inner wall of the first column 1 via the connecting spring 6, the advertising frame 5 can be directly pulled out to replace the poster. After replacement, the advertising frame 5 is pushed back to its original position, and its internal limiting mechanism is activated: the fixed rack 8 meshes with the drive gear 9, driving the top transmission gear 10 to rotate, causing the connecting racks 11 on the left and right sides to move the bonding plate 12 relative to each other, clamping the poster to limit the offset. After the limiting mechanism completes the limiting, its signal is transmitted to the control module of the magnetic locking mechanism, triggering the magnetic locking mechanism to maintain the locked state, ensuring the stability of the advertising gate 3.

[0029] Example 2: To facilitate full rotation of the advertising gate 3, please refer to the attached document. Figure 1 Attached Figures Figure 3 and attached Figure 7The system includes a first column 1 and a second column 2. The bottoms of both the first column 1 and the second column 2 are fixed to the bottom surface. An advertising gate 3 is rotatably mounted on one side of the first column 1. The advertising gate 3 achieves bidirectional rotation on the outside of the first column 1 via a motor core assembly 4. The motor core assembly 4 includes a motor core body 41 installed inside the first column 1. The output end of the motor core body 41 is fixedly connected to the bottom center of a rotating gear 42. A mating gear 43 is meshed with the outside of the rotating gear 42. The tops of both the rotating gear 42 and the mating gear 43 are rotatably mounted inside a dustproof housing 44. A rotating shaft 45 is fixed to the bottom of the mating gear 43. The bottom of the first column 1 is fixedly connected to one end of the advertising door 3. The magnetic locking mechanism includes a locking unit that cooperates with the rotating shaft 45. The locking unit is used to lock the rotating shaft 45 when the advertising door 3 rotates to a preset position. The magnetic locking mechanism includes an electromagnet 13 and a magnetic block 14. The electromagnet 13 is fixed to the inner side of the first column 1 and corresponds to the position of the rotating shaft 45. The magnetic block 14 is fixed to the outer side of the rotating shaft 45. When the advertising door 3 rotates to the closed position, the electromagnet 13 is energized to generate magnetic force and attracts the magnetic block 14 to lock the advertising door 3. The bottom outer side of the dustproof housing 44 is installed on the top of the first column 1. The first column 1 and the second column 2 have the same height.

[0030] The first column 1 and the second column 2 are fixed to the bottom surface. The advertising gate 3 achieves bidirectional rotation through the motor core assembly 4. The motor core body 41 is installed inside the first column 1, and its output end drives the rotating gear 42 to rotate. The rotating gear 42 meshes with the mating gear 43 for transmission. The mating gear 43 drives the advertising gate 3 to rotate outside the first column 1 through the rotating shaft 45 at the bottom. The dustproof shell 44 protects the rotating gear 42 and the mating gear 43 to ensure stable transmission. When the advertising gate 3 rotates to the closed position, the electromagnet 13 inside the first column 1 is energized to generate magnetic force, which attracts the magnetic block 14 outside the rotating shaft 45, thus locking the advertising gate 3 by locking the rotating shaft 45. When it is necessary to rotate the gate, the electromagnet 13 is de-energized, the magnetic force disappears, the magnetic block 14 separates from the electromagnet 13, and the motor core assembly 4 drives the gate to rotate in the opposite direction to complete the opening action. The first column 1 and the second column 2 are at the same height to ensure structural balance.
