Description

Technical Field

[0001] The invention belongs to the field of electric bicycles. Background Art

[0002] Many places in China have introduced policies that explicitly require electric bicycle riders to wear helmets; for example, the "Shanghai Non-Motor Vehicle Safety Management Regulations" stipulate that those who fail to wear helmets will face fines; if shared electric vehicles do not provide helmets, users may be punished for not wearing them, and the company may bear joint liability.

[0003] Proactively providing helmets can avoid legal risks. However, helmets are easily lost in the shared bicycle industry, so a device that can be more conveniently operated and stably lock the helmet is needed, while also considering the problem of accidental locking. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a locking system and working method for the basket and helmet of an electric vehicle, which can prevent the helmet from being accidentally locked when the user has not returned the vehicle while ensuring the stability of the locked state.

[0005] Technical solution: To achieve the above-mentioned purpose, the locking system of the vehicle basket and the helmet of the electric vehicle of the present invention comprises a vehicle basket and a helmet; a lock tongue plug box is provided in the lower part of the helmet, and an insertion port is provided on the lower side of the lock tongue plug box;

The lock comprises a lock body transmission box fixedly installed in the lock housing, and a lock tongue guide box is integrally provided on the upper end of the lock body transmission box. Lock tongues on both sides of the lock tongue guide box can be retracted into and extended out of the lock tongue guide box under the drive of the driving device, and the lock tongue guide box passes upward through the hollow opening and protrudes from the upper side of the lock housing;

[0008] When the safety helmet is buckled in the basket of the bicycle basket, the lock tongue guide box is inserted upward into the insertion opening on the lower side of the lock tongue insertion box, and the two lock tongues on both sides of the lock tongue guide box are respectively extended out from the lock tongue openings on both sides of the lock tongue insertion box.

[0009] Furthermore, a transverse spring is provided in the lock tongue guide box, and both ends of the transverse spring elastically push the ends of the two lock tongues that are close to each other, so that the two lock tongues automatically extend outward without the action of external force.

[0010] Furthermore, an air piston cylinder and a piston rod are coaxially arranged in the transverse spring, one end of the first locking tongue close to the second locking tongue is integrally fixedly connected to the air piston cylinder, and one end of the second locking tongue close to the first locking tongue is integrally fixedly connected to the piston rod, and a piston is arranged at the end of the piston rod; the piston moves in the air piston cylinder, and when the first locking tongue and the second locking tongue are both in an extended state, the piston is located inside the end of the air piston cylinder;

[0011] The air column chamber is inside the air piston cylinder. A negative pressure relief hole is hollowed out on a side of the air column chamber near the second lock tongue to connect to the atmospheric pressure. When the first lock tongue and the second lock tongue are both in the extended state, the negative pressure relief hole is located on the side of the piston near the first lock tongue, thereby connecting the air column chamber to the atmospheric pressure.

[0012] When the first lock tongue and the second lock tongue are both in a retracted state, the negative pressure release hole is located on the side of the piston away from the first lock tongue, so that the negative pressure release hole is not connected to the air column compartment;

[0013] An air guide channel is provided inside the first lock tongue, one end of the air guide channel is connected to one end of the air column bin, and the other end is connected to atmospheric pressure, and a one-way valve is provided in the air guide channel. Under the one-way conduction of the one-way valve, the air in the air column bin can be discharged to the outside through the air guide channel, and the air from the outside cannot be sucked into the air column bin through the air guide channel.

[0014] Furthermore, an air pressure sensor is provided at the left end of the air column bin.

[0015] Furthermore, a guide rail and a slider are provided in the lock body transmission box, the slider moves under the guidance of the guide rail, and the guide direction of the guide rail is perpendicular to the movement direction of the lock tongue;

[0016] The slider is symmetrically provided with a first guide groove and a second guide groove, and the extension directions of the first guide groove and the second guide groove are both set at an angle to the extension direction of the guide rail. The two lock tongues are respectively recorded as the first lock tongue and the second lock tongue; the lower ends of the first lock tongue and the second lock tongue are fixedly connected to the first slide column and the second slide column extending downward through the first connecting arm and the second connecting arm respectively; the first slide column and the second slide column are respectively slidably fitted in the first guide groove and the second guide groove.

[0017] Furthermore, slip rings are rotatably sleeved on the outside of the first sliding post and the second sliding post.

[0018] Furthermore, when the slider moves along the guide rail, under the guidance of the first guide groove and the second guide groove, the first slide post and the second slide post move toward and away from each other.

[0019] Furthermore, a transmission tooth body is arranged in a linear array along the guide rail on one side of the slider, a gear is provided in the lock body transmission box, and the gear is engaged with the transmission tooth body; a drive motor for driving the gear is provided in the lock body transmission box.

[0020] Furthermore, the working method of the locking system of the electric vehicle basket and the helmet is as follows: when the user scans the code to pick up the vehicle and unlocks it, the controller drives the slider to move along the guide rail through the motor, and the first lock tongue and the second lock tongue move closer to each other and retract, thereby releasing the locking state;

[0021] After the user scans the code to return the bike, the user buckles the helmet he is wearing into the basket of the bike basket. The controller drives the slider through the motor to force the slider to move in the opposite direction along the guide rail, forcing the first slide post and the second slide post to move away from each other. When the piston deviates to the right relative to the air piston cylinder and passes the negative pressure release hole, the motor is powered off.

[0022] Beneficial effects: In the unlocked state, the two lock tongues automatically extend outward under the elastic thrust of the transverse spring, thereby entering the locked state. Under the thrust of the transverse spring, even if there are external disturbance factors such as shaking, the two lock tongues will not automatically retract and unlock, thereby ensuring the stability of the locked state;

[0023] At the same time, it also achieves the state of maintaining unlocking when the motor is powered off. Even if the user buckles the safety helmet he is wearing into the basket of the bicycle for a short time before returning the bicycle, the safety helmet will not be locked, avoiding the situation of accidental locking.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] As attached Figures 1 to 8 The locking system of the electric vehicle basket and the helmet is shown as follows: Figures 1 to 3 As shown, it includes a bicycle basket 2 and a safety helmet 1. The inner contour of the basket compartment 50 of the bicycle basket 2 is adapted to the outer contour of the safety helmet 1; a lock tongue plug box 9 is integrally provided on the inner side of the lower rear end of the safety helmet 1, an insertion port 10 is provided on the lower side of the lock tongue plug box 9, and lock tongue ports 11 are symmetrically hollowed out on both sides of the lock tongue plug box 9; a convex lock shell 60 is provided at the bottom of the basket compartment 50, and a lock tongue guide box 4 is provided on the upper part of the lock shell 60; the two ends of the lock tongue guide box 4 can symmetrically extend and retract the lock tongue; a slope is provided on the upper part of the lock tongue.

[0035] When the safety helmet 1 is buckled in the basket compartment 50 of the vehicle basket 2, the lock tongue guide box 4 is inserted upward into the insertion port 10 on the lower side of the lock tongue insertion box 9, and the two lock tongues in the extended state on both sides of the lock tongue guide box 4 respectively protrude from the lock tongue ports 11 on both sides of the lock tongue insertion box 9; a hollow opening 61 is provided on the upper part of the lock housing 60, and a lock 80 is fixedly installed in the lock housing 60. The lock 8 includes a lock body transmission box 6 fixedly installed in the lock housing 60, and a lock tongue guide box 4 is integrally provided on the upper end of the lock body transmission box 6. The lock tongue guide box 4 passes through the hollow opening 61 upward and protrudes from the upper side of the lock housing 60, and the lock housing 60 serves as a rainproof.

[0036] like Figures 3 to 5 As shown, both sides of the lock tongue guide box 4 are provided with lock tongue guide openings 100 for guiding the lock tongue; the lock tongue can be retracted into the lock tongue guide box 4 and extended to the lock tongue guide box 4 under the drive of the driving device; a transverse spring 17 is provided in the lock tongue guide box 4, and the two ends of the transverse spring 17 elastically push the ends of the two lock tongues close to each other, so that the two lock tongues automatically extend outward without the action of external force; a guide rail 32 and a slider 18 are provided in the lock body transmission box 6, and the slider 18 moves under the guidance of the guide rail 32, and the guide direction of the guide rail 32 is perpendicular to the action direction of the lock tongue.

[0037] like Figures 6 to 8 As shown, the slider 18 is symmetrically provided with a first guide groove 20a and a second guide groove 20b. The extension directions of the first guide groove 20a and the second guide groove 20b are both set at an angle with the extension direction of the guide rail 32, and the angle is 40° to 50°. In a top view, the first guide groove 20a and the second guide groove 20b are combined into an "eight" shape; the two lock tongues are respectively recorded as the first lock tongue 5a and the second lock tongue 5b; the lower ends of the first lock tongue 5a and the second lock tongue 5b are fixedly connected to the downward extending first slide column 19a and the second slide column 19b through the first connecting arm 16a and the second connecting arm 16b respectively.

[0038] The first sliding post 19a and the second sliding post 19b are slidably fitted in the first guide groove 20a and the second guide groove 20b respectively;

[0039] In order to make the first slide post 19a and the second slide post 19b slide more smoothly in the first guide groove 20a and the second guide groove 20b respectively, the first slide post 19a and the second slide post 19b are both rotatably sleeved with slip rings, which can be replaced by bearings.

[0040] When the slider 18 moves along the guide rail 32, the first slide post 19a and the second slide post 19b move toward and away from each other under the guidance of the first guide groove 20a and the second guide groove 20b. A transmission tooth body 31 is arranged in a linear array along the guide rail 32 on one side of the slider 18. A gear 30 is provided in the lock body transmission box 6, and the gear 30 meshes with the transmission tooth body 31.

[0041] A drive motor for driving the gear 30 is arranged in the lock body transmission box 6 .

[0042] The following problems exist when only adopting the above structure:

[0043] During the period from when the user picks up the bike to when he returns it, the helmet 1 should be available to the user at any time and should not be locked by mistake during this period. For example, if the user rides for a while and takes a break, but it is not time to return the bike yet, if the user buckles the helmet 1 he is wearing into the basket 50 of the bike basket 2 for short-term storage, the helmet 1 will be automatically locked. If the user wants to prevent the helmet from being locked by mistake during the period from when he picks up the bike to when he returns it, the first lock tongue 5a and the second lock tongue 5b need to be in a retracted state at all times. Since the transverse spring 17 has a restoring force, after the user scans the code to pick up the bike, the controller controls the motor to drive the slider 18 to move to unlock it. If this unlocked state needs to be further maintained, the motor needs to continuously apply torque without rotating to maintain it. This not only results in continuous power consumption, but also easily causes the motor to burn out.

[0044] Based on the above problems, this solution provides the following optimization solutions based on the above solutions:

[0045] An air piston cylinder 42 and a piston rod 40 are coaxially arranged in the transverse spring 17. The end of the first locking tongue 5a close to the second locking tongue 5b is integrally fixedly connected to the air piston cylinder 42. The end of the second locking tongue 5b close to the first locking tongue 5a is integrally fixedly connected to the piston rod 40. A piston 36 is arranged at the end of the piston rod 40. The piston 36 moves in the air piston cylinder 42. When the first locking tongue 5a and the second locking tongue 5b are both in the extended state, the piston 36 is located inside the end of the air piston cylinder 42.

[0046] The air piston cylinder 42 contains an air column bin 35. A side portion of the air column bin 35 near the second lock tongue 5b is hollowed out to form a negative pressure relief hole 34 connected to the atmospheric pressure. When the first lock tongue 5a and the second lock tongue 5b are both in the extended state, the negative pressure relief hole 34 is located on the side of the piston 36 close to the first lock tongue 5a, so that the negative pressure relief hole 34 connects the air column bin 35 to the atmospheric pressure; when the first lock tongue 5a and the second lock tongue 5b are both in the retracted state, the negative pressure relief hole 34 is located on the side of the piston 36 away from the first lock tongue 5a, so that the negative pressure relief hole 34 is not connected to the air column bin 35.

[0047] An air guide channel 33 is provided inside the first lock tongue 5a, one end of the air guide channel 33 is connected to one end of the air column bin 35, and the other end is connected to the atmospheric pressure, and a one-way valve 37 is provided in the air guide channel 33. Under the one-way conduction of the one-way valve 37, the air in the air column bin 35 can be discharged to the outside through the air guide channel 33, and the air from the outside cannot be sucked into the air column bin 35 through the air guide channel 33; an air pressure sensor is provided at the left end of the air column bin 35.

[0048] Working principle:

[0049] Assuming that the electric bicycle is initially unlocked, the helmet 1 is buckled in the basket compartment 50 of the basket 2, and the motor is powered off, the two locking tongues automatically extend outward under the elastic thrust of the transverse spring 17, thereby entering the locked state. Under the thrust of the transverse spring 17, even if there are external disturbances such as shaking, the two locking tongues will not automatically retract and unlock, thereby ensuring the stability of the locked state.

[0050] When the user scans the code to pick up the car and unlocks it, the controller drives the slider 18 along the guide rail 32 through the motor. Under the guidance of the first guide groove 20a and the second guide groove 20b, the first slide post 19a and the second slide post 19b are forced to move closer to each other, so that the first lock tongue 5a and the second lock tongue 5b are retracted closer to each other, thereby releasing the locked state. In the process of the first slide post 19a and the second slide post 19b moving closer to each other and retracting, the piston 36 pushes left relative to the air piston cylinder 42, causing the volume of the air column bin 35 to gradually decrease, thereby causing the gas in the air column bin 35 to gradually be discharged through the negative pressure release hole 34. When the piston 36 passes the negative pressure release hole 34 to the left, the volume of the air column bin 35 continues to decrease, thereby causing the air in the air column bin 35 to be smoothly discharged to the outside through the one-way conduction of the one-way valve 37 and the air guide channel 33; when the first lock tongue 5a and the second lock tongue 5b are fully retracted into the lock tongue guide box 4, the air column bin 35 When the first and second locking tongues 5a and 5b begin to move away from each other by the force of the spring 17, the ends of the first and second locking tongues 5a and 5b have not yet been exposed from both sides of the locking tongue guide box 4, due to the action of the one-way valve 37, the piston 36 deflects to the right relative to the air piston cylinder 42, which will form a stable negative pressure in the air column chamber 35. The negative pressure prevents the piston 36 from further deflecting to the right relative to the air piston cylinder 42 and forms a balancing force with the transverse spring 17, thereby maintaining the status quo, thereby preventing the first and second locking tongues 5a and 5b from automatically extending under the thrust of the transverse spring 17, thereby maintaining the unlocked state when the motor is powered off. Even if the user buckles the worn safety helmet 1 in the basket chamber 50 of the bicycle basket 2 for a short time before returning the bicycle, the safety helmet 1 will not be locked.

[0051] After the user scans the code to return the vehicle, the user buckles the safety helmet 1 worn by the user into the basket compartment 50 of the vehicle basket 2. The controller drives the slider 18 along the guide rail 32 through the motor to force the reverse displacement. Under the guidance of the first guide groove 20a and the second guide groove 20b, the first slide post 19a and the second slide post 19b are forced to move away from each other, so that the piston 36 is forced to deflect to the right relative to the air piston cylinder 42, so that the negative pressure in the air column compartment 35 gradually becomes stronger. When the piston 36 is forced to deflect to the right relative to the air piston cylinder 42 until it passes over the negative pressure release hole 34, the air column compartment 35 in the negative pressure state is connected to the outside through the negative pressure release hole 34. At this time, the external atmospheric pressure air The air column chamber 35 enters through the negative pressure release hole 34, so that the air column chamber 35 returns to atmospheric pressure, thereby releasing the leftward force of the negative pressure on the piston 36, avoiding the problem that the first lock tongue 5a and the second lock tongue 5b automatically retract and unlock under the action of the negative pressure in the air column chamber 35 in the subsequent locked state; at this time, the motor is powered off, and since the negative pressure in the air column chamber 35 has been released, the two lock tongues automatically tend to extend outward under the elastic thrust of the transverse spring 17, thereby entering the locked state. Under the thrust of the transverse spring 17, even if there are external disturbance factors such as shaking, the two lock tongues will not automatically retract and unlock, thereby ensuring the stability of the locked state.

[0052] like Figure 9 As shown, a push switch protrusion port 87 is provided on the upper side of the lock body transmission box 6 of this solution, and a push switch 89 protruding upward is provided in the push switch protrusion port 87; when the safety helmet 1 is buckled in the basket compartment 50 of the vehicle basket 2, the edge of the safety helmet 1 will press the push switch 89, thereby allowing the controller to recognize that the safety helmet 1 is in the inserted state.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
