Description

Technical Field

[0001] This utility model relates to the field of buzzers, specifically a buzzer with anti-collision properties. Background Technology

[0002] A buzzer is an electronic component that emits continuous or intermittent sounds, typically used for alarms, reminders, or indications. It produces sound by changing the current or voltage, causing its internal oscillator to vibrate. Common buzzers are divided into passive and active types. Passive buzzers require an external power supply, while active buzzers have their own oscillator and can be directly controlled by voltage to produce sound. In practical applications, buzzers are widely used in electronic watches, home appliances, automobiles, and other fields. However, existing buzzers lack shock resistance, making them easily damaged after impacts. Therefore, new technical solutions are needed to address this issue. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a buzzer with anti-collision performance, so as to solve the technical problem that the current buzzer does not have anti-collision performance during use, making the buzzer easily damaged after collision.

[0004] To achieve the objective of this utility model, the technical solution adopted is as follows: A buzzer with anti-collision performance is designed, comprising:

[0005] A buffer mechanism includes through holes on both sides of a mounting plate and a crash plate on one side of the mounting plate. An upper connecting plate and a lower connecting plate are provided on both sides of the end of the crash plate closest to the mounting plate. The upper connecting plate and the lower connecting plate are both through the through holes. A fixing plate is fixedly connected to the end of the upper connecting plate and the lower connecting plate away from the crash plate. A buffer spring is fixedly connected between the fixing plate and the mounting plate.

[0006] The flipping mechanism includes a connecting shaft rotatably connected to both sides of a circular hole in the middle of a mounting plate via bearings. A flipping plate is fixedly connected to the outer side of the connecting shaft. A buzzer body is bolted to the end of the flipping plate near the anti-collision plate. A tooth is fixedly connected to the end of the upper connecting plate near the lower connecting plate. Both ends of the connecting shaft rotatably pass through the circular hole and are placed in a through hole. A gear is fixedly connected to the outer side of the connecting shaft in the through hole, and the gear meshes with the tooth.

[0007] Preferably, the connecting shaft has a hollow structure, and the power-carrying wire of the buzzer body passes through the inner cavity of the connecting shaft and is electrically connected to an external power source.

[0008] Preferably, a limiting groove is formed at the bottom of the inner cavity of the through hole, and a limiting block is fixedly connected to the bottom of the lower connecting plate. Both the limiting groove and the limiting block are inverted T-shaped, and the limiting block is slidably connected in the limiting groove.

[0009] Preferably, the end of the anti-collision plate away from the upper connecting plate is rotatably threaded through by a bolt, and the bolt is threadedly connected to the surfaces of the upper and lower connecting plates.

[0010] Preferably, the anti-collision plate has multiple rectangular holes.

[0011] Preferably, an anti-slip pad is fixedly connected to the outer side of the flip plate.

[0012] Preferably, a baffle is fixedly connected to the upper connecting plate on one side of the tooth, and the height of the baffle is greater than the height of the tooth.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention combines a shock absorber plate, a flip plate, a connecting shaft, gears, teeth, an upper connecting plate, a lower connecting plate, a buffer spring, and a fixing plate. When a collision occurs, the shock absorber plate contacts the object it is colliding with, causing the upper and lower connecting plates to move. This stretches the buffer spring, thus buffering the impact force. During the movement of the upper connecting plate, the teeth drive the gears to rotate, which in turn drives the connecting shaft to rotate. The connecting shaft then rotates the flip plate 180°, flipping the buzzer body to the side away from the shock absorber plate. This provides better protection for the buzzer body and further improves its anti-collision effect. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A buzzer with anti-collision performance, see [link to example]. Figures 1 to 5 The system includes: a buffer mechanism, comprising through holes 11 on both sides of the mounting plate 1 and a crash plate 12 on one side of the mounting plate 1. The crash plate 12 has an upper connecting plate 16 and a lower connecting plate 15 on both sides of the end closest to the mounting plate 1. Both the upper connecting plate 16 and the lower connecting plate 15 pass through the through holes 11. A fixing plate 18 is fixedly connected to the end of the upper connecting plate 16 and the lower connecting plate 15 away from the crash plate 12. A buffer spring 19 is fixedly connected between the fixing plate 18 and the mounting plate 1; and a flipping mechanism. The rotating mechanism includes a connecting shaft 22 rotatably connected to both sides of the central circular hole 17 of the mounting plate 1 via bearings. A flip plate 2 is fixedly connected to the outer side of the connecting shaft 22. A buzzer body 21 is connected to the end of the flip plate 2 near the anti-collision plate 12 via bolts 14. A tooth is fixedly connected to the end of the upper connecting plate 16 near the lower connecting plate 15. Both ends of the connecting shaft 22 rotatably pass through the circular hole 17 and are placed in the through hole 11. A gear 23 is fixedly connected to the outer side of the connecting shaft 22 in the through hole 11, and the gear 23 meshes with the tooth.

[0023] During operation, when a collision occurs, the anti-collision disc 12 contacts the object it collides with, and the compression of the anti-collision disc 12 causes the upper connecting plate 16 and the lower connecting plate 15 to move, thereby stretching the buffer spring 19 and buffering the impact force generated by the collision. During the movement of the upper connecting plate 16, the gear 23 is driven to rotate through the teeth, the gear 23 drives the connecting shaft 22 to rotate, and the connecting shaft 22 drives the flipping plate 2 to rotate 180°, thereby flipping the buzzer body 21 to the side away from the anti-collision disc 12, thus better protecting the buzzer body 21 and further improving the anti-collision effect of the buzzer.

[0024] For details, see Figure 4 The connecting shaft 22 is a hollow structure. The power-carrying wire of the buzzer body 21 passes through the inner cavity of the connecting shaft 22 and is electrically connected to the external power source. This design can effectively prevent the power-carrying wire from breaking off from the buzzer body 21 when the buzzer body 21 is flipped.

[0025] Further, see Figure 3 and Figure 5 The bottom of the inner cavity of the through hole 11 is provided with a limiting groove 3, and the bottom of the lower connecting plate 15 is fixedly connected to a limiting block 31. Both the limiting groove 3 and the limiting block 31 are inverted T-shaped. The limiting block 31 is slidably connected in the limiting groove 3. By sliding the limiting block 31 in the limiting groove 3, the movement of the lower connecting plate 15 can be guided, thereby guiding the movement of the anti-collision plate 12 and improving the stability of the movement of the anti-collision plate 12 during collision.

[0026] It is worth noting that, see Figure 1 The end of the anti-collision plate 12 away from the upper connecting plate 16 is rotatably connected by a bolt 14, and the bolt 14 is threadedly connected to the surfaces of the upper connecting plate 16 and the lower connecting plate 15. The bolt 14 facilitates the disassembly of the anti-collision plate 12, and facilitates the independent replacement of the damaged anti-collision plate 12, thereby reducing the replacement cost.

[0027] It is worth noting that, see Figure 1 The anti-collision plate 12 has multiple rectangular holes 13. By setting the rectangular holes 13, the sound obstruction of the buzzer body 21 by the anti-collision plate 12 is reduced.

[0028] It is worth mentioning that, see Figure 3 An anti-slip pad 24 is fixedly connected to the outer side of the flip plate 2. The anti-slip pad 24 increases the friction between the flip plate 2 and the round hole 17, thereby improving the stability of the round hole 17 connected to the flip plate 2 and preventing vibration from causing the flip plate 2 to rotate and affecting the normal use of the buzzer body 21.

[0029] It is worth mentioning that, see Figure 5 A baffle 4 is fixedly connected to the upper connecting plate 16 on one side of the tooth. The height of the baffle 4 is greater than the height of the tooth. By setting the baffle 4, when the baffle 4 contacts the gear 23, the flip plate 2 flips 180° to ensure that the buzzer body 21 can be better protected.
