Description

Technical Field

[0001] The invention belongs to the technical field of mobile phone cases, and in particular relates to a multi-purpose mobile phone case. Background Art

[0002] In today's digital age, smartphones have become an indispensable tool in people's lives. They are used very frequently and accompany people in various daily activities and different environmental scenarios. However, the fragility of mobile phones, especially the problem that the screen and body are easily damaged when accidentally dropped, has always been a major pain point for users.

[0003] Existing mobile phone protection methods are relatively simple, mostly limited to passive physical protection, and lack intelligent active protection mechanisms. For example, some mobile phone cases only rely on increasing the thickness of the case or using materials with certain cushioning properties to reduce the impact when falling, but cannot make targeted protective action adjustments according to the actual falling state of the mobile phone (such as falling height, angle, speed, etc.), and the ability to protect the mobile phone screen is poor, resulting in the problem of screen cracking due to accidental falls.

[0004] Combining the above two points, we can find that it is difficult to avoid the above problems at the same time when using the existing mobile phone cases on the market, thus failing to achieve the desired effect. Therefore, we propose a multi-purpose mobile phone case that can effectively solve the problem of protecting the mobile phone when it accidentally falls, thereby improving the safety of the mobile phone during use. Summary of the invention

[0005] The purpose of the present invention is to provide an existing multi-purpose mobile phone case, which has the advantages of providing a protection structure, an intelligent drop protection system and a telescopic protection structure. When the mobile phone is detected to be in a falling state, the intelligent drop protection system quickly makes a judgment and starts a corresponding protection action, controls the protection structure to work, so that the protection structure flexibly protects the screen and the back of the mobile phone, and the protection structure simultaneously drives the telescopic protection structure to extend, which can form an additional protection barrier on the side of the mobile phone, further enhancing the overall protection effect of the mobile phone, thereby achieving all-round protection of the mobile phone, greatly reducing the risk of damage to the mobile phone due to falling, and can also sound an alarm when the mobile phone falls, reminding the user to check whether the mobile phone is damaged in time, further reflecting the humanized design and multi-functional characteristics of the mobile phone case.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a multi-purpose mobile phone case, comprising a protective case and an intelligent drop protection system, wherein a flexible connecting plate is arranged on the left side of the protective case, and a protective cover is arranged on the left side of the flexible connecting plate, a protective structure is arranged on the bottom of the protective case, and two telescopic protective structures are arranged on the right side inside the protective case, and the telescopic protective structure is connected to the protective structure through a pipeline; The protective structure includes a fixed shell, the fixed shell is arranged at the bottom of the protective shell, and an air storage bin is arranged inside the fixed shell, the top of the air storage bin is connected to a first capsule through a pipeline, and the surface of the first capsule is tightly fitted to a limit frame, the surface of the limit frame is connected to the inner wall of the fixed shell, a first flexible contact plate is arranged on the top of the first capsule, a second capsule is arranged at the bottom inside the protective cover plate, and the second capsule is connected to the air storage bin through a pipeline, and a second flexible contact plate is arranged at the bottom of the second capsule; The intelligent fall protection system includes a microprocessor, the input end of the microprocessor is bidirectionally electrically connected to an acceleration sensor and a gyroscope sensor, the input end of the microprocessor is bidirectionally electrically connected to a trigger switch, and the trigger switch is arranged on the right side of the telescopic protection structure, the output end of the microprocessor is unidirectionally electrically connected to a buzzer, the output end of the microprocessor is unidirectionally electrically connected to a micro air pump, and the micro air pump is arranged inside the air storage bin.

[0007] By adopting the above technical solution, by setting up a protection structure, an intelligent drop protection system and a telescopic protection structure, when it is detected that the mobile phone is in a falling state, the intelligent drop protection system quickly makes a judgment and starts the corresponding protection action, controls the operation of the protection structure, and enables the protection structure to flexibly protect the screen and back of the mobile phone. At the same time, the protection structure drives the telescopic protection structure to extend, which can form an additional protection barrier on the side of the mobile phone, further enhancing the overall protection effect of the mobile phone, thereby achieving all-round protection for the mobile phone, greatly reducing the risk of damage to the mobile phone due to falling, and can also issue an alarm when the mobile phone falls, reminding the user to check whether the mobile phone is damaged in time, further reflecting the humanized design and multi-functional characteristics of the mobile phone case.

[0008] The present invention is further configured as follows: a protective shell is provided inside the air storage bin, and a micro air pump is provided inside the protective shell; a distribution pipe is provided inside the protective shell, and one end of the distribution pipe is connected to the micro air pump.

[0009] By adopting the above technical solution, a protective shell and a distribution pipe are set up. The protective shell limits the position of the micro air pump and protects the micro air pump. The distribution pipe is set up so that the gas extracted from the micro air pump can be more evenly and efficiently transported to the gas storage bin and the subsequently connected bladder through the distribution pipe. This uniform gas distribution helps the bladder to expand quickly and stably when inflated, thereby better playing a buffering and protective role.

[0010] The present invention is further configured as follows: a fixing belt is provided on the right side of the top of the protective cover plate, and a push-on male buckle is provided on the side of the fixing belt close to the bottom of the protective shell, and a push-on female buckle used in conjunction with the push-on male buckle is provided at the bottom of the protective shell, and magnetic blocks are provided on the surfaces of the push-on male buckle and the push-on female buckle, and the two magnetic blocks are magnetically attracted to each other.

[0011] By adopting the above technical solution, through the setting of the fixing belt and the push-on male buckle and the push-on female buckle cooperating with the bottom of the protective case, the protective cover can be opened and closed with the protective case conveniently and quickly. The user can easily open the protective cover to operate the mobile phone, and can quickly close it after use, thereby providing protection for the front of the mobile phone and improving the convenience of the user in using the mobile phone case. By setting the magnetic block and utilizing the magnetic attraction between the two, the firmness of the connection between the two can be further enhanced.

[0012] The present invention is further configured as follows: the fixing belt is composed of two connecting belts, and a connecting shell is sleeved between the surfaces of the two connecting belts, the connecting belt is slidably arranged inside the connecting shell, and a plurality of elastic ropes are arranged between opposite sides of the two connecting belts.

[0013] By adopting the above technical solution, a connecting belt, a connecting shell and an elastic rope are set. When the first bladder and the second bladder expand and squeeze the first flexible contact plate and the second flexible contact plate to contact the screen and the back of the mobile phone respectively, the top connecting belt and the elastic rope will be stretched. Therefore, the elasticity of the elastic rope can limit the upward displacement of the protective cover, so that the first flexible contact plate and the second flexible contact plate can fit tightly with the mobile phone, avoiding the occurrence of gaps between the three and affecting the protection effect.

[0014] The present invention is further configured as follows: anti-collision corner blocks are arranged at the four corners of the surface of the protective shell, and the anti-collision corner blocks are made of flexible material, a module opening is opened on the right side of the bottom of the protective shell, and a raised peripheral edge formed integrally with the protective shell is arranged at the bottom of the module opening.

[0015] By adopting the above technical solution, by setting up anti-collision corner blocks, when the mobile phone accidentally falls or is hit from the side, the impact force can be borne first, and a buffering and dispersion effect can be played, thereby reducing the risk of damage to the mobile phone due to corner impacts, such as screen cracking and body deformation, and further improving the overall protection function of the mobile phone case. By using the raised edge in conjunction with the module mouth, since the height of the raised edge is greater than the mobile phone camera module, the camera module of the mobile phone can be protected to a certain extent.

[0016] The present invention is further configured as follows: the telescopic protective structure includes a hollow plate and a fixed frame, the hollow plate is arranged on the right side inside the protective shell, and the right side of the hollow plate is connected to a plurality of hollow cylinders, a push rod is slidably arranged inside the hollow cylinder, and the right side of the push rod is connected to the fixed frame, a push plate is bolted to the left side of the push rod, a return spring is sleeved on the surface of the push rod, and the return spring is respectively connected to the push plate and the inner wall of the hollow cylinder on one side close to the two, and the hollow plate is connected to the air storage bin through a pipeline.

[0017] By adopting the above technical solution and setting a telescopic protective structure, when the air inside the air storage bin is discharged, part of the air enters the interior of the hollow plate through the pipe, and enters the interior of the hollow cylinder to move the push plate and the push rod, and to contract the reset spring. The push rod drives the fixed frame to extend, forming a protective barrier on the side of the mobile phone, effectively preventing the side of the mobile phone from directly colliding with the ground or other hard objects, reducing the risk of deformation of the side of the mobile phone or damage to internal parts due to impact, and is an important supplement to the overall protection system of the mobile phone, enhancing the protection capability of the mobile phone case in different directions.

[0018] The present invention is further configured as follows: a plurality of guide plates arranged obliquely are bolted to the right side of the inner wall of the hollow plate, the guide plates are used in conjunction with the hollow cylinder, and a gap is formed between the guide plates and the left side of the inner wall of the hollow plate.

[0019] By adopting the above technical solution, by setting a guide plate, the air flow direction can be guided into the hollow tube, and the gap formed between the guide plate and the hollow plate can facilitate the air to flow into the next hollow tube.

[0020] The present invention is further configured as follows: the trigger switch includes an elastic plate, the elastic plate is arranged on the right side of the fixed frame, and a plurality of arc-shaped protrusions are arranged on the right side of the elastic plate, an elastic member is arranged between the elastic plate and the inner wall of the fixed frame, and a moving contact and a static contact are respectively arranged on the side of the elastic plate opposite to the inner wall of the fixed frame, and the moving contact is used in conjunction with the static contact.

[0021] By adopting the above technical solution, a trigger switch is set. When the mobile phone is used normally, the elastic plate of the trigger switch is in the initial position under the action of the elastic member, and the moving contact and the static contact are in a separated state. When the mobile phone falls, the elastic plate collides with the ground so that the elastic plate can overcome the elasticity of the elastic member and move. As the elastic plate moves, the moving contact and the static contact gradually approach and contact. When they contact, the collision signal is transmitted to the microprocessor. The microprocessor controls the buzzer to warn according to the received signal, reminding the user to check whether the mobile phone is damaged in time, further reflecting the humanized design and multi-functional characteristics of the mobile phone case.

[0022] The present invention is further configured such that: the acceleration sensors are arranged at four corners inside the protective shell, and the gyroscope sensor is arranged inside the fixed shell.

[0023] By adopting the above technical solution, the acceleration sensors are arranged at the four corners inside the protective shell, so that the acceleration changes of the mobile phone can be sensed from different directions. When the mobile phone falls accidentally, the acceleration will change sharply. These changes will be captured by the acceleration sensors at the four corners at the same time, and the signals will be transmitted to the microprocessor. At the same time, the gyroscope sensor located inside the fixed shell will monitor the rotation angle and angular velocity changes of the mobile phone during the fall, and transmit this information to the microprocessor. After receiving the comprehensive data from the acceleration sensor and the gyroscope sensor, the microprocessor analyzes and judges to determine whether the mobile phone is in a falling state and the specific situation of the fall, and then decides whether to activate the protection mechanism and how to activate the protection mechanism.

[0024] The present invention is further configured as follows: the input end of the intelligent fall protection system is unidirectionally electrically connected to a power management module, and the input end of the power management module is unidirectionally electrically connected to a power supply module, and the power supply module is a battery.

[0025] By adopting the above technical solution, the power management module and the power supply module are used to provide power supply through the intelligent drop protection system, ensuring that all components of the entire system can continue to work normally. This stable power supply method does not require users to frequently charge the mobile phone case separately or replace the battery, reducing the user's maintenance costs and operating troubles. At the same time, it ensures that the intelligent drop protection system is always on standby during the use of the mobile phone, and can respond to the drop of the mobile phone at any time, thereby improving the practicality and reliability of the mobile phone case.

[0026] In summary, the present invention has the following beneficial effects: By setting up a protective structure, when the mobile phone accidentally falls, it can provide effective protection from multiple key parts, and can provide buffer protection for the back and front of the mobile phone respectively, to prevent the screen and body from directly colliding with the ground or other hard objects, significantly reducing the risk of serious damage to the mobile phone due to falling, and providing reliable all-round protection for the mobile phone; By setting up a telescopic protection structure, it can quickly extend out when the phone falls, forming a solid protective barrier on the side of the phone. This design specifically solves the problem of the phone being easily damaged when it hits the ground on its side. Working together with the protective structure, it achieves comprehensive protection for the front, back and sides of the phone, greatly improving the overall protection capabilities of the phone in various possible falling scenarios.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] Embodiment 1: refer to Figure 1-6 9. A multi-purpose mobile phone case, comprising a protective case 1 and an intelligent drop protection system 2, wherein a flexible connecting plate 3 is arranged on the left side of the protective case 1, and a protective cover plate 4 is arranged on the left side of the flexible connecting plate 3, a protective structure 5 is arranged on the bottom of the protective case 1, and two telescopic protective structures 6 are arranged on the right side inside the protective case 1, and the telescopic protective structure 6 is connected to the protective structure 5 through a pipeline; The protective structure 5 includes a fixed shell 51, which is arranged at the bottom of the protective shell 1, and an air storage bin 52 is arranged inside the fixed shell 51, and a first capsule 53 is connected to the top of the air storage bin 52 through a pipeline, and the surface of the first capsule 53 is tightly fitted to the limiting frame 54, and the surface of the limiting frame 54 is connected to the inner wall of the fixed shell 51, and a first flexible contact plate 55 is arranged on the top of the first capsule 53, and a second capsule 56 is arranged at the bottom of the protective cover plate 4, and the second capsule 56 is connected to the air storage bin 52 through a pipeline, and a second flexible contact plate 57 is arranged at the bottom of the second capsule 56; The intelligent fall protection system 2 includes a microprocessor 21, the input end of the microprocessor 21 is bidirectionally electrically connected to an acceleration sensor 22 and a gyroscope sensor 23, the input end of the microprocessor 21 is bidirectionally electrically connected to a trigger switch 24, and the trigger switch 24 is arranged on the right side of the telescopic protection structure 6, the output end of the microprocessor 21 is unidirectionally electrically connected to a buzzer 25, the output end of the microprocessor 21 is unidirectionally electrically connected to a micro air pump 26, and the micro air pump 26 is arranged inside the air storage bin 52.

[0031] like Figure 4 As shown, a protective shell 7 is provided inside the air storage bin 52, and the micro air pump 26 is provided inside the protective shell 7. A distribution pipe 8 is provided inside the protective shell 7, and one end of the distribution pipe 8 is connected to the micro air pump 26. By providing the protective shell 7 and the distribution pipe 8, the protective shell 7 limits the position of the micro air pump 26 and protects the micro air pump 26. The distribution pipe 8 is provided so that the gas extracted from the micro air pump 26 can be more evenly and efficiently transported to the air storage bin 52 and the subsequently connected bladder through the distribution pipe 8. This uniform gas distribution helps the bladder to expand quickly and stably when inflated, thereby better playing a buffering and protective role.

[0032] like Figure 6 As shown, a fixing belt 9 is provided on the right side of the top of the protective cover 4, and a push-on male buckle 10 is provided on the side of the fixing belt 9 close to the bottom of the protective shell 1, and a push-on female buckle 11 used in conjunction with the push-on male buckle 10 is provided at the bottom of the protective shell 1. Magnetic blocks 12 are provided on the surfaces of the push-on male buckle 10 and the push-on female buckle 11, and the two magnetic blocks 12 are magnetically attracted to each other. Through the setting of the fixing belt 9 and the push-on male buckle 10 and the push-on female buckle 11 matched with the bottom of the protective shell 1, the protective cover 4 can be conveniently and quickly opened and closed with the protective shell 1. The user can easily open the protective cover 4 to operate the mobile phone and quickly close it after use, thereby providing protection for the front of the mobile phone and improving the convenience of the user using the mobile phone case. Through the setting of the magnetic block 12, the magnetic attraction between the two can be utilized to further enhance the firmness of the connection between the two.

[0033] like Figure 6 As shown, the fixing belt 9 is composed of two connecting belts 13, and a connecting shell 14 is sleeved between the surfaces of the two connecting belts 13, the connecting belt 13 is slidably arranged inside the connecting shell 14, and a plurality of elastic ropes 15 are arranged between the opposite sides of the two connecting belts 13. By arranging the connecting belt 13, the connecting shell 14 and the elastic rope 15, when the first capsule 53 and the second capsule 56 expand and squeeze the first flexible contact plate 55 and the second flexible contact plate 57 to contact the screen and the back of the mobile phone respectively, the top connecting belt 13 and the elastic rope 15 will be stretched. Therefore, the elasticity of the elastic rope 15 can limit the upward displacement of the protective cover 4, so that the first flexible contact plate 55 and the second flexible contact plate 57 can fit tightly with the mobile phone, avoiding the occurrence of gaps between the three and affecting the protection effect.

[0034] like Figure 5As shown, anti-collision corner blocks 16 are provided at the four corners of the surface of the protective shell 1, and the anti-collision corner blocks 16 are made of flexible material. A module opening 17 is opened on the right side of the bottom of the protective shell 1, and a raised edge 18 formed integrally with the protective shell 1 is provided at the bottom of the module opening 17. By providing the anti-collision corner blocks 16, when the mobile phone accidentally falls or is hit from the side, it can first bear the impact force and play a buffering and dispersion role, thereby reducing the risk of damage to the mobile phone such as screen cracking and body deformation due to corner impact, and further improving the overall protective function of the mobile phone case. By using the raised edge 18 in conjunction with the module opening 17, since the height of the raised edge 18 is greater than the camera module of the mobile phone, the camera module of the mobile phone can be protected to a certain extent.

[0035] like Fig. 9 As shown, the acceleration sensors 22 are arranged at the four corners inside the protective shell 1, and the gyroscope sensor 23 is arranged inside the fixed shell 51. By arranging the acceleration sensors 22 at the four corners inside the protective shell 1, the acceleration changes of the mobile phone can be sensed from different directions. When the mobile phone falls accidentally, the acceleration will change sharply. These changes will be captured by the acceleration sensors 22 at the four corners at the same time, and the signals will be transmitted to the microprocessor 21. At the same time, the gyroscope sensor 23 located inside the fixed shell 51 will monitor the rotation angle and angular velocity changes of the mobile phone during the falling process, and transmit this information to the microprocessor 21. After receiving the comprehensive data from the acceleration sensor 22 and the gyroscope sensor 23, the microprocessor 21 analyzes and judges to determine whether the mobile phone is in a falling state and the specific situation of the fall, and then decides whether to start the protection mechanism and how to start the protection mechanism.

[0036] like Fig. 9 As shown, the input end of the intelligent drop protection system 2 is unidirectionally electrically connected to the power management module 20, and the input end of the power management module 20 is unidirectionally electrically connected to the power supply module 21, and the power supply module 21 is a battery. The power management module 20 and the power supply module 21 provide power supply through the intelligent drop protection system 2, ensuring that the various components of the entire system can continue to work normally. This stable power supply method does not require users to frequently charge or replace batteries for the mobile phone case separately, reducing users' maintenance costs and operating troubles, and at the same time ensuring that the intelligent drop protection system 2 is always on standby during the use of the mobile phone, and can respond to the falling situation of the mobile phone at any time, thereby improving the practicality and reliability of the mobile phone case.

[0037] Brief description of the use process: When the mobile phone falls accidentally, the acceleration sensor 22 keenly captures the sharp change of the acceleration of the mobile phone in three-dimensional space, and the gyroscope sensor 23 monitors the rotation angle and angular velocity changes of the mobile phone during the falling process, and transmits the signal to the microprocessor 21. When the microprocessor 21 determines that the mobile phone is in a falling state, it controls the micro air pump 26 to extract gas from the gas storage bin 52, and preliminarily distributes and guides the extracted gas through the distribution pipe 8 in the protective shell 7, so that the gas can be more evenly and efficiently discharged along the connecting pipe to the first capsule 53 and the gas storage bin 52 connected to the pipeline. After the gas is transported by the second capsule 56, the gas is respectively filled into the first capsule 53 at the bottom of the protective shell 1 and the second capsule 56 in the protective cover 4, the first capsule 53 expands rapidly under the action of the gas pressure connected through the pipeline at the top of the gas storage bin 52, and the second capsule 56 is transported by the gas in its own connecting pipeline. As the first capsule 53 and the second capsule 56 expand, the first flexible contact plate 55 and the second flexible contact plate 57 approach the screen and back of the mobile phone, forming a buffer protection area before the mobile phone contacts the ground or other hard objects, thereby effectively dispersing the impact force and preventing the screen and back of the mobile phone from being directly damaged by severe collision.

[0038] Embodiment 2: refer to Figure 7-8 , including a protective shell 1 and an intelligent fall protection system 2, a flexible connecting plate 3 is arranged on the left side of the protective shell 1, and a protective cover plate 4 is arranged on the left side of the flexible connecting plate 3, a protective structure 5 is arranged at the bottom of the protective shell 1, and two telescopic protective structures 6 are arranged on the right side inside the protective shell 1, and the telescopic protective structure 6 is connected to the protective structure 5 through a pipeline.

[0039] like Figure 7 As shown, the telescopic protective structure 6 includes a hollow plate 61 and a fixed frame 62. The hollow plate 61 is arranged on the right side inside the protective shell 1, and the right side of the hollow plate 61 is connected to a plurality of hollow cylinders 63. A push rod 64 is slidably arranged inside the hollow cylinder 63, and the right side of the push rod 64 is connected to the fixed frame 62. A push plate 65 is bolted to the left side of the push rod 64. A return spring 66 is sleeved on the surface of the push rod 64, and the return spring 66 is connected to the push plate 65 and the inner wall of the hollow cylinder 63 on one side thereof, respectively. The hollow plate 61 is connected to the gas storage bin 52 through a pipeline, and the passage By setting up the telescopic protective structure 6, when the air inside the air storage bin 52 is discharged, part of the air enters the inside of the hollow plate 61 through the pipe, and enters the inside of the hollow cylinder 63 to move the push plate 65 and the push rod 64, and shrink the return spring 66. The push rod 64 drives the fixed frame 62 to extend, forming a protective barrier on the side of the mobile phone, effectively preventing the side of the mobile phone from directly colliding with the ground or other hard objects, reducing the risk of deformation of the side of the mobile phone or damage to internal parts due to impact, and is an important supplement to the overall protection system of the mobile phone, enhancing the protection ability of the mobile phone case in different directions.

[0040] like Figure 7 As shown, a plurality of oblique guide plates 19 are bolted to the right side of the inner wall of the hollow plate 61. The guide plates 19 are used in conjunction with the hollow tube 63, and a gap is formed between the guide plates 19 and the left side of the inner wall of the hollow plate 61. By setting the guide plates 19, the air flow direction can be guided to the hollow tube 63, and the gap formed between the guide plates 19 and the hollow plate 61 can facilitate the air to flow to the next hollow tube 63.

[0041] like Figure 8 As shown, the trigger switch 24 includes an elastic plate 241, which is arranged on the right side of the fixed frame 62, and a plurality of arc-shaped protrusions 242 are arranged on the right side of the elastic plate 241, an elastic member 243 is arranged between the elastic plate 241 and the inner wall of the fixed frame 62, and a moving contact 244 and a static contact 245 are respectively arranged on the side opposite to the inner wall of the fixed frame 62 of the elastic plate 241, and the moving contact 244 and the static contact 245 are used in conjunction with each other. By setting the trigger switch 24, when the mobile phone is used normally, the elastic plate 241 of the trigger switch 24 is in the action of the elastic member 243. The mobile phone case is in the initial position, and the moving contact 244 and the static contact 245 are in a separated state. When the mobile phone falls, the elastic plate 241 hits the ground, so that the elastic plate 241 can overcome the elasticity of the elastic member 243 to move. As the elastic plate 241 moves, the moving contact 244 and the static contact 245 gradually approach and contact. When in contact, the collision signal is transmitted to the microprocessor 21. The microprocessor 21 controls the buzzer 25 to warn according to the received signal, reminding the user to check whether the mobile phone is damaged in time, which further reflects the humanized design and multi-functional characteristics of the mobile phone case.

[0042] A brief description of the usage process: When the mobile phone falls and triggers the protection mechanism, the gas pressure in the gas storage bin 52 increases, and the gas flows into the hollow plate 61 through the pipeline. Several oblique guide plates 19 bolted to the right side of the inner wall of the hollow plate 61 guide the gas to flow in a specific direction, pushing the push rod 64 in the hollow cylinder 63 to overcome the elastic force of the return spring 66 and move outward. The push rod 64 drives the fixed frame 62 to extend, forming a protective barrier on the side of the mobile phone to prevent the side of the mobile phone from directly colliding with the ground or other hard objects, reducing the risk of deformation or damage to internal parts of the side of the mobile phone due to impact, and the elastic plate 241 collides with the ground so that the elastic plate 241 can overcome the elasticity of the elastic member 243 to move. As the elastic plate 241 moves, the moving contact 244 and the static contact 245 gradually approach and contact. When in contact, the collision signal will be transmitted to the microprocessor 21, and the microprocessor 21 will control the buzzer 25 to warn according to the received signal.

[0043] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
