DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide an electric control lock and an electric vehicle to solve the technical problem that the existing electric vehicle needs to be unlocked with a key.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment 1

[0031] like Figure 1-Figure 8 As shown, the present embodiment provides an electric control lock 100, including a housing 1 and a control mechanism, a driving mechanism 4, an actuator 5, an overload protection mechanism 6 and a lock pin 3 installed in the housing 1. The control mechanism is electrically connected to the driving mechanism 4 and is used to control the action of the driving mechanism 4. The overload protection mechanism 6 can connect the driving mechanism 4 and the actuator 5, and the actuator 5 is connected to the lock pin 3. The driving mechanism 4 is used to drive the actuator 5 to move, and the actuator 5 drives the lock pin 3 to reciprocate. One end of the lock pin 3 extends out of the housing 1 and is used to unlock or lock the handlebars of the electric vehicle, thereby directly realizing the switch lock through electric control without the aid of a mechanical key. The overload protection mechanism 6 can transmit the output force of the driving mechanism 4 to the actuator 5, thereby driving the action of the lock pin 3 to realize the opening and closing of the lock, and the overload protection mechanism 6 can protect the driving mechanism 4 after the actuator 5 reaches the execution stroke. The protection function can prevent the execution stroke from driving the lock pin 3 to move into place, because the lock pin 3 cannot continue to move, and the driving mechanism 4 is still running, thereby causing damage to the driving mechanism 4.

[0032] Specifically, the overload protection mechanism 6 includes a driving gear 9, a driven gear 10 and a rack 17, the rack 17 is slidably connected in the housing 1, the outer periphery of the driving gear 9 is respectively meshed with the output shaft of the driving mechanism 4 and the outer periphery of the driven gear 10, the outer periphery of the driven gear 10 is meshed with the rack 17, and the rack 17 is connected to the actuator 5. Preferably, the driving gear 9 and the driven gear 10 are both designed as large and small gears, that is, the large gear of the driving gear 9 is meshed with the output shaft of the driving mechanism 4, the small gear of the driving gear 9 is meshed with the large gear of the driven gear 10, and the small gear of the driven gear 10 is meshed with the rack 17. When the driving mechanism 4 rotates, it can drive the driving gear 9 and the driven gear 10 to rotate, and the driven gear 10 drives the rack 17 to move back and forth, and the rack 17 drives the actuator 5 to move back and forth, so as to realize the reciprocating movement of the lock pin 3, thereby locking the electric vehicle when the lock pin 3 is extended, and unlocking it when it is retracted. Preferably, the driving mechanism 4 is a motor, and the setting of the overload protection mechanism 6 can avoid damage to the motor and the gear mechanism.

[0033] A guide shaft 18 is fixed in the housing 1, and the axis of the guide shaft 18 is parallel to the moving direction of the lock pin 3. The rack 17 is slidably connected to the guide shaft 18, and the rack 17 can slide back and forth along the axial direction of the guide shaft 18, and drive the actuator 5 to move to push out or retract the lock pin 3. The rack 17 is supported and guided by the guide shaft 18 to ensure the stable sliding of the rack 17, thereby ensuring the stability of the movement of the lock pin 3 and the accuracy of the direction.

[0034] The length of the rack 17 is slightly larger than the execution stroke of the actuator 5, so that the disengagement position of the rack 17 is slightly larger than the execution stroke of the actuator 5, that is, the rack 17 can still make a small displacement after the locking pin 3 moves into place. When the rack 17 drives the actuator 5 to move to the execution stroke, the locking pin 3 moves into place, and the driving mechanism 4 continues to operate. With the movement of the rack 17, the second elastic member 8 can be compressed, and the rack 17 is disengaged from the driven gear 10. At the same time, under the action of the elastic restoring force of the second elastic member 8, the second elastic member 8 always gives the rack 17 a thrust to move closer to the driven gear 10, even if the rack 17 is meshed with the driven gear 10 again, to ensure that the next time the driven gear 10 rotates in the opposite direction, it can mesh with the rack 17 again. Before the driving mechanism 4 stops, the rack 17 and the driven gear 10 form a "meshing-disengagement" reciprocating action to avoid damage to various structures.

[0035] As another protection mechanism, the length of the rack 17 is greater than the execution stroke of the actuator 5, that is, the rack 17 is always meshed with the driven gear 10; the driven gear 10 is a split design, including an upper gear 14 and a lower gear 13, the upper gear 14 is meshed with the rack 17, the lower end of the upper gear 14 is coaxially fixed with an upper connecting member 16, and the lower end of the upper connecting member 16 is circumferentially provided with a plurality of upper serrations, that is, each upper serration is arranged in a ring, and the upper end of the lower gear 13 is coaxially fixed with a lower connecting member 15, and the upper end of the lower connecting member 15 is circumferentially provided with a plurality of upper serrations. The upper connecting member 16 and the lower connecting member 15 are coaxially arranged, and the upper and lower saw teeth can mesh with each other. After the rack 17 drives the actuator 5 to move to the execution stroke, the rack 17 cannot move forward, and the upper gear 14 cannot move. At the same time, the driving mechanism 4 drives the lower gear 13 to operate, so that the upper and lower saw teeth move relative to each other along the contact surface, and a tendency to separate from each other is generated, thereby avoiding damage to the driving mechanism 4 and the driven gear 10.

[0036] The upper gear 14 and the lower gear 13 are both sleeved on a connecting shaft 11 and arranged up and down. A first elastic member 12 is also sleeved on the connecting shaft 11. One end of the first elastic member 12 is fixed to the end of the connecting shaft 11 away from the upper gear 14. The other end of the first elastic member 12 is connected to the lower gear 13. The first elastic member 12 is always in a compressed state, so that the first elastic member 12 can give the lower gear 13 an upward thrust, and the lower connecting member 15 is meshed with the upper connecting member 16 to ensure that the upper gear 14 and the lower gear 13 rotate synchronously, thereby The actuator 5 and the lock pin 3 are driven to move. When the rack 17 drives the actuator 5 to move to the execution stroke, the upper gear 14 and the upper connecting member 16 cannot rotate, and the driving mechanism 4 drives the lower gear 13 and the lower connecting member 15 to continue to rotate, so that the lower sawtooth rotates relative to the upper sawtooth along the inclined surface that fits the upper sawtooth, and compresses the first elastic member 12 downward to make the upper connecting member 16 and the lower connecting member 15 move in the direction of separation from each other, so as to ensure that the rotation of the driving mechanism 4 and the fixing of the rack 17 do not affect each other, avoiding damage to the mechanism. Preferably, the first elastic member 12 is a spring.

[0037] The actuator 5 includes a push block 7 and a second elastic member 8. Preferably, the second elastic member 8 is a spring. A slide groove is provided on the lower end surface of the push block 7, and a mounting groove is provided on the upper end surface of the rack 17. The second elastic member 8 is located in the area surrounded by the slide groove and the mounting groove. The inner wall at one end of the mounting groove away from the locking pin 3 is the mounting wall. One end of the second elastic member 8 is fixed on the mounting wall. The other end of the second elastic member 8 abuts against the inner wall in the mounting groove opposite to the mounting wall, and the inner wall on the side of the slide groove close to the locking pin 3. That is, in a normal state, both ends of the second elastic member 8 are in contact with the two inner walls of the slide groove and the two inner walls of the mounting groove. The push block 7 is in contact with the rack 17, thereby making the push block 7 elastically connected to the rack 17. When the lock pin 3 encounters resistance and cannot complete the locking action, the push block 7 cannot move forward. At this time, since the driving mechanism 4 is still running and the second elastic member 8 exists, the rack 17 continues to move forward, and the mounting wall and an inner wall of the slide groove jointly squeeze the second elastic member 8, causing the second elastic member 8 to be compressed, which not only avoids damage to the driving mechanism 4, but also realizes energy storage. After the lock pin 3 is adjusted, the push block 7 drives the lock pin 3 to be pushed out under the action of the elastic restoring force of the second elastic member 8 to achieve locking. The same applies when the lock pin 3 encounters resistance when it needs to be unlocked.

[0038] A PCB board 19 is also fixed in the housing 1, and two detection switches 20 are installed on the PCB board 19. The two detection switches 20 are used to detect the positions of the push block 7 and the rack 17 respectively. The push block 7 and the rack 17 move and act on the two detection switches 20 respectively to detect the positions of the push block 7 and the rack 17. Since the lock pin 3 is prone to encounter resistance when unlocking or locking, the positions of the push block 7 and the rack 17 are detected by the two detection switches 20 respectively to understand whether the unlocking or locking is successful. For example, it can be set that when the push block 7 and the rack 17 are evenly spaced, the position of the push block 7 and the rack 17 is detected. When the two detection switches 20 are not in contact with each other, it is judged that the lock pin 3 is in the unlocked state. When the push block 7 and the rack 17 are not in contact with the detection switch 20, it is judged that the lock pin 3 is in the locked state. When one detection switch 20 shows contact and the other detection switch 20 shows no contact, it proves that the lock pin 3 is stuck, not locked or unlocked in place. Both detection switches 20 are electrically connected to the control mechanism to understand the unlocking state in real time; the control mechanism is wirelessly connected to the external controller, and can control the drive mechanism 4 to open or close after the external controller issues an instruction, and then directly realize the opening and closing of the lock through electrical control. Preferably, the external controller can be a mobile phone or a card, which can be opened and closed directly by wireless signal transmission, which is convenient to use; the detection switch 20 is a waterproof switch, and a travel switch or a Hall switch can be selected as long as it can meet the use requirements.

[0039] A plastic cavity 21 is also provided in the housing 1. The driving gear 9, the driven gear 10 and the driving mechanism 4 are all installed in the plastic cavity 21, and the output end of the driven gear 10 extends to the outside of the plastic cavity 21. The PCB board 19 leads the circuit into the plastic cavity 21. The PCB board 19 forms the upper end surface of the plastic cavity 21, and the side walls of the plastic cavity 21 are waterproofed by rubber parts. Preferably, the output end of the driven gear 10 is equipped with an O-ring, which is compressed and matched with the end surface of the plastic cavity 21 to achieve waterproofing. The wall surfaces of the plastic cavity 21 are ultrasonically welded to achieve dustproof and waterproofing.

[0040] A pull rope 2 is also fixed on the side of the push block 7 away from the lock pin 3. The pull rope 2 extends to the outside of the shell 1 and can be hidden in any position in the electric vehicle according to actual needs without affecting the normal use of the electric vehicle. The pull rope 2 is used by the user to manually unlock the vehicle, forming a mechanical unlocking. When unlocking is required, the pull rope 2 is directly pulled in the direction away from the lock pin 3, driving the push block 7 and the lock pin 3 to move in the unlocking direction to achieve unlocking.
