Description

Technical Field

[0001] The utility model relates to a lock which electronically controls whether a battery box can be removed, in particular to a battery box lock of an electric bicycle. Background Art

[0002] In today's society, many electronic devices use batteries as a power source, and these batteries are often just snapped onto the electronic devices without being actually locked. This design is fine if used in home or portable electronic devices, but if used in electronic devices that are placed outdoors, the batteries may be stolen by malicious people.

[0003] To prevent theft, a lock may be provided on the battery, but in this case, when the user wants to remove the battery, he or she will also need a key, which causes inconvenience in use. Utility Model Content

[0004] Based on the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides an electronically controlled battery box lock, which can be unlocked by electronic control, so there is no need to carry a key, which is convenient to use.

[0005] In order to achieve the above-mentioned purpose, the technical means adopted by the utility model is to design an electric-controlled battery box lock, which comprises:

[0006] A base having a first base engaging seat, wherein the first base engaging seat comprises an electronic controller and an engaging member; the electronic controller can drive the engaging member to move or rotate;

[0007] A battery box is detachably arranged on the base and has a first battery engaging seat; the engaging member of the first base engaging seat can be moved or rotated to engage with the first battery engaging seat, and when the engaging member engages with the first battery engaging seat, the battery box cannot be separated from the base; the electronic controller of the first base engaging seat can drive the engaging member to move or rotate to disengage from the first battery engaging seat.

[0008] The advantage of the utility model is that an electronic controller and a clamping member are arranged on the base combined with the battery box, and the clamping member can be moved or rotated to clamp the first battery clamping seat on the battery box. Therefore, the clamping member on the base is usually clamped with the first battery clamping seat to prevent the battery box from being separated from the base. When unlocking, it is only necessary to control the electronic controller through a signal (for example, through a mobile phone APP) to allow the clamping member on the base to be separated from the first battery clamping seat, so that the battery box and the base can be unlocked and the battery box can be removed. Therefore, the utility model can lock the battery box to prevent theft, and can also unlock the battery box without using or carrying a key, thereby facilitating use.

[0009] Furthermore, the electric-controlled battery box lock, wherein the base further includes a second base engaging seat, the first base engaging seat and the second base engaging seat are respectively located at two ends of the base; the battery box further includes a second battery engaging seat, the first battery engaging seat and the second battery engaging seat are respectively located at two ends of the battery box; the battery box can be placed between the first base engaging seat and the second base engaging seat of the base; when the battery box is placed between the first base engaging seat and the second base engaging seat of the base, the second battery engaging seat and the second base engaging seat are engaged with each other; when the engaging part of the first base engaging seat is disengaged from the first battery engaging seat, the second battery engaging seat can be tilted away from the base to disengage from the second base engaging seat.

[0010] Furthermore, the electronically controlled battery box lock further has a guiding structure, which is arranged on the first base snap-in seat and the first battery snap-in seat. When the second battery snap-in seat and the second base snap-in seat are obliquely combined with each other, the first battery snap-in seat can be inserted into the first base snap-in seat along the guiding structure toward the base.

[0011] Furthermore, in the electronically controlled battery box lock, the engaging member normally moves or rotates in the direction of engaging with the first battery engaging seat.

[0012] Furthermore, in the electronically controlled battery box lock, a rotating member is provided on the electronic controller, and an eccentric portion protrudes from the rotating member. The electronic controller moves the rotating member away from the first battery engaging seat by rotating the rotating member or rotates the engaging member to disengage the engaging member from the first battery engaging seat.

[0013] Furthermore, the electronically controlled battery box lock further has a manual unlocking member, which is provided on one of the first base engagement seat and the first battery engagement seat, and selectively engages the other of the first base engagement seat and the first battery engagement seat; when the engagement member is disengaged from the first battery engagement seat and the manual unlocking member is disengaged from the first base engagement seat and the other of the first battery engagement seat, the battery box can be disengaged from the base.

[0014] Furthermore, in the electronically controlled battery box lock, at least one separation component is provided in the first base engagement seat, which tends to push the first battery engagement seat away from the base; when the engagement member is disengaged from the first battery engagement seat, the separation component pushes the first battery engagement seat away from the base, so that the manual unlocking member engages with the other of the first base engagement seat and the first battery engagement seat.

[0015] Furthermore, the electronically controlled battery box lock further comprises a locking element sensor, which is electrically connected to the electronic controller and is used to sense whether the locking element moves or rotates to lock the first battery locking seat.

[0016] Furthermore, in the electronically controlled battery box lock, the engaging part sensor includes two sensing units and two sensed units, and the two sensing units are electrically connected to the electronic controller; a rotating part is provided on the electronic controller, and the electronic controller moves or rotates the engaging part by rotating the rotating part, and the rotation of the rotating part in two opposite directions by the electronic controller will push the two sensed units toward the two sensing units respectively, and each sensed unit can be sensed by the corresponding sensing unit after being pushed.

[0026] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose of the invention with reference to the accompanying drawings and preferred embodiments of the present invention.

[0027] See also Figure 1 , Figure 2 and Fig.17 As shown, the electric control battery box lock of the utility model comprises a base 10 and a battery box 20. Preferably, it further comprises a manual unlocking member 30, a guide structure 40 and a locking member sensor 50. The utility model is preferably used on a bicycle, and can be an electric bicycle. In this case, the base 10 is a part of the bicycle frame, and can be preferably installed on the lower tube 90 of the bicycle, but it is not limited thereto, and can also be installed at other positions of the bicycle or used in any other occasions other than bicycles.

[0028] The battery box 20 is a box body for placing batteries, but can also be considered as the shell of batteries. In addition, the battery box 20 can be a box body or shell of batteries of various sizes and purposes.

[0029] See also Figure 2 , Figure 3 and Fig.10 As shown, the aforementioned base 10 has a first base snap-fit ​​seat 11. In the present embodiment, the base 10 further includes a base 13 and a second base snap-fit ​​seat 12. The base 13 preferably extends in a straight line. The first base snap-fit ​​seat 11 and the second base snap-fit ​​seat 12 are respectively connected to the two ends of the base 13, but this is not limited to it. The base 10 may be in other shapes, and the first base snap-fit ​​seat 11 and the second base snap-fit ​​seat 12 may not be located at the two ends of a straight line.

[0030] The aforementioned battery box 20 can be detachably arranged on the base 10, and has a first battery engaging seat 21. In the present embodiment, the battery box 20 further includes a second battery engaging seat 22. The first battery engaging seat 21 and the second battery engaging seat 22 are respectively located at the two ends of the battery box 20. The battery box 20 can be placed between the first base engaging seat 11 and the second base engaging seat 12 of the base 10, and preferably, the spacing between the first base engaging seat 11 and the second base engaging seat 12 corresponds to the length of the battery box 20, so that the two ends of the battery box 20 (the first battery engaging seat 21 and the second battery engaging seat 22) can be respectively attached to the first base engaging seat 11 and the second base engaging seat 12 of the base 10. Preferably, the first base engaging seat 11 and the second base engaging seat 12 of the base 10 are respectively engaged with the first battery engaging seat 21 and the second battery engaging seat 22 of the battery box 20. However, the present invention is not limited to this, and the second base engaging seat 12 and the second battery engaging seat 22 may be omitted, and the first battery engaging seat 21 may be engaged with the first base engaging seat 11 alone. For example, a groove is formed on the base 10, and the battery box 20 is accommodated in the groove, the first battery engaging seat 21 faces the bottom of the groove, and the first base engaging seat 11 is also located at the bottom of the groove. In this way, the battery box 20 can be engaged with the first base engaging seat 11 and the first battery engaging seat 21 alone.

[0031] See also Figures 3 to 6 and Fig.17 As shown, the aforementioned first base engaging seat 11 includes an electronic controller 111 and an engaging member 112. The electronic controller 111 can drive the engaging member 112 to move or rotate, and the engaging member 112 can move or rotate to engage with the first battery engaging seat 21. When the engaging member 112 engages with the first battery engaging seat 21, the battery box 20 cannot be separated from the base 10, and the electronic controller 111 can drive the engaging member 112 to move or rotate to disengage from the first battery engaging seat 21.

[0032] In this embodiment, the electronic controller 111 is driven to rotate the engaging member 112 to disengage from the first battery engaging seat 21, and the electronic controller 111 has a controller area network bus (CAN bus) and a Bluetooth low energy (BLE) system, and can also be equipped with a global positioning system (GPS). In addition, the electronic controller 111 can be controlled by wire or wireless means, and preferably, the electronic controller 111 can be controlled by an APP on a mobile phone.

[0033] In this embodiment, the engaging member 112 normally moves or rotates in the direction of engaging with the first battery engaging seat 21. In other words, the electronic controller 111 is only used to disengage the engaging member 112 from the first battery engaging seat 21. Therefore, when the battery box 20 is installed, when the first battery engaging seat 21 is engaged with the first base engaging seat 11, the first battery engaging seat 21 can push the engaging member 112 away without first moving or rotating the engaging member 112 in the opposite direction, which is convenient for operation. In addition, preferably, a retracting portion 1121 is provided on the engaging member 112, which is preferably arc-shaped and will be abutted by the first battery engaging seat 21, so it is more conducive to the first battery engaging seat 21 to push the engaging member 112 away.

[0034] Preferably, at least one engaging elastic component 113 is provided in the first base engaging seat 11, which is specifically a torsion spring and is used to rotate the engaging member 112 toward the direction of engaging the first battery engaging seat 21 in a normal state, but the present invention is not limited thereto, and other methods may be used, such as two magnets with opposite magnetic properties, etc. In addition, the engaging member 112 may not move or rotate toward the direction of engaging the first battery engaging seat 21 in a normal state, and the electronic controller 111 may directly cause the engaging member 112 to move or rotate toward the direction of engaging the first battery engaging seat 21.

[0035] In the present embodiment, the electronic controller 111 is a motor (preferably a servo motor or a stepper motor) and moves or rotates the engaging member 112 through a rotating member 114. The rotating member 114 has an eccentric portion 1141 protruding therefrom. The electronic controller 111 moves or rotates the engaging member 112 in a direction away from the first battery engaging seat 21 by rotating the rotating member 114, so that the engaging member 112 is separated from the first battery engaging seat 21. Preferably, the eccentric portion 1141 protrudes from the rotating member 114 along the axial direction of the rotating member 114, but deviates from the center of the rotating member 114. Therefore, after the rotating member 114 rotates, the eccentric portion 1141 can abut against and drive the engaging member 112 to rotate, but the present invention is not limited thereto. The eccentric portion 1141 can also protrude radially from the periphery of the rotating member 114. In this way, the rotating member 114 can be regarded as a cam, which can also abut against and drive the engaging member 112 to rotate. In addition, the electronic controller 111 can also push one end of the engaging member 112 by moving to rotate the engaging member 112. In this case, the electronic controller 111 can be a cylinder or a linear motor. In addition, the engaging member 112 can also be in a moving form instead of a rotating form. When the first battery engaging seat 21 is to be engaged, the engaging member 112 can simply be moved to extend into the first battery engaging seat 21. This can also prevent the first battery engaging seat 21 from separating.

[0036] See also Figure 4 , Figure 5 and Figure 7 As shown, the manual unlocking member 30 is disposed on one of the first base engaging seat 11 and the first battery engaging seat 21, and selectively engages with the other of the first base engaging seat 11 and the first battery engaging seat 21. When the engaging member 112 is separated from the first battery engaging seat 21 and the manual unlocking member 30 is separated from the other of the first base engaging seat 11 and the first battery engaging seat 21, the battery box 20 can be separated from the base 10.

[0037] See also Figure 4 , Figure 8 and Fig. 9 As shown, in this embodiment, the manual unlocking member 30 is disposed on the first battery engaging seat 21 and selectively engages with the first base engaging seat 11. Preferably, the manual unlocking member 30 is elastic and can be pulled. Normally, at least one abutting portion 31 of the manual unlocking member 30 abuts against the first base engaging seat 11, so that the battery box 20 cannot move (upward) away from the base 10 (such as Figure 8 As shown), after the manual unlocking member 30 is pulled, the abutting portion 31 of the manual unlocking member 30 can be separated from the first base engaging seat 11 (as shown in FIG. Fig. 9 As shown), the battery box 20 is no longer prevented from being separated from the base 10.

[0038] See also Figure 4 , Figure 7 and Fig.17As shown, in this embodiment, at least one separation component 115 is disposed in the first base engaging seat 11, which tends to push the first battery engaging seat 21 away from the base 10 (upward). When the engaging member 112 is separated from the first battery engaging seat 21, the separation component 115 pushes the first battery engaging seat 21 away from the base 10 (upward), and at this time, the manual unlocking member 30 is preferably engaged with the other of the first base engaging seat 11 and the first battery engaging seat 21. In this embodiment, the abutting portion 31 of the manual unlocking member 30 is abutted (upward) against the first base engaging seat 11, and then the manual unlocking member 30 is operated to enable the battery box 20 to be separated from the base 10. However, this is not limited to this, and the engaging member 112 and the manual unlocking member 30 can also be engaged at the same time. At this time, the manual unlocking member 30 can be unlocked first, and then the engaging member 112 can be separated from the first battery engaging seat 21. However, the separation component 115 can also be used in the case where there is no manual unlocking member 30. When the engaging member 112 is separated from the first battery engaging seat 21, the first battery engaging seat 21 of the battery box 20 will be pushed away from the base 10, and the first battery engaging seat 21 can be separated from the first base engaging seat 11. In addition, in the present embodiment, the separation component 115 is an elastic component, and preferably a compression spring, but the present invention is not limited thereto.

[0039] See also Figure 2 and Figures 10 to 13 As shown, in this embodiment, when the battery box 20 is placed between the first base snap-fit ​​seat 11 and the second base snap-fit ​​seat 12 of the base 10, the second battery snap-fit ​​seat 22 and the second base snap-fit ​​seat 12 are snap-fitted to each other, and when the snap-fit ​​piece 112 of the first base snap-fit ​​seat 11 is disengaged from the first battery snap-fit ​​seat 21, the second battery snap-fit ​​seat 22 can be tilted away from the base 10 (upward) to be disengaged from the second base snap-fit ​​seat 12.

[0040] In this embodiment, at least one side protrusion 121 and a top protrusion 122 are protruded from the second base engaging seat 12, and preferably there are two side protrusions 121. At least one side recess 221 and a top recess 222 are recessed on the second battery engaging seat 22, and preferably there are two side recesses 221. The side recess 221 and the top recess 222 are used to accommodate the side protrusion 121 and the top protrusion 122 respectively. However, this is not limited to the above, and the number and position of each protrusion and recess can be adjusted according to needs, and the recess can also be changed to be located on the second base engaging seat 12, and the protrusion can be changed to be located on the second battery engaging seat 22.

[0041] Preferably, the top and bottom surfaces of the side protrusion 121 and the top protrusion 122 can be inclined surfaces, and the top inner wall surfaces and bottom inner wall surfaces of the side recess 221 and the top recess 222 can be inclined surfaces, thereby facilitating the second battery engaging seat 22 to tilt away from the base 10 (upward) and disengage from the second base engaging seat 12.

[0042] See also Figure 3 , Figure 5 and Figure 7 As shown, the aforementioned guide structure 40 is provided on the first base engaging seat 11 and the first battery engaging seat 21. When the second battery engaging seat 22 and the second base engaging seat 12 are obliquely coupled to each other, the first battery engaging seat 21 can be inserted into the first base engaging seat 11 along the guide structure 40 toward the base 10 (downward), thereby preventing the first battery engaging seat 21 from swinging (left and right) relative to the first base engaging seat 11. Preferably, the guide structure 40 includes at least one guide block 41 and at least one guide groove 42, and preferably three guide blocks 41 and three guide grooves 42. The guide block 41 is formed on the first battery engaging seat 21, and the guide groove 42 is formed on the first base engaging seat 11, but it is not limited thereto. The guide block 41 can also be formed on the first base engaging seat 11, and the guide groove 42 is formed on the first battery engaging seat 21.

[0043] See also Figure 8 As shown, in this embodiment, the place where the abutting portion 31 of the manual unlocking member 30 abuts (upward) against the first base engaging seat 11 is the periphery of the guide groove 42, and the place where the separation component 115 pushes against the first battery engaging seat 21 is the guide block 41, but not limited to this.

[0044] See also Figures 17 to 20 As shown, the aforementioned engaging member sensor 50 is electrically connected to the electronic controller 111, and is used to sense whether the engaging member 112 moves or rotates to engage the first battery engaging seat 21. Preferably, the engaging member sensor 50 includes two sensing units 51 and two sensed units 52, the two sensing units 51 are electrically connected to the electronic controller 111, and the electronic controller 111 rotates the rotating member 114 in two opposite directions to push the two sensed units 52 toward the two sensing units 51 respectively, and each sensed unit 52 can be sensed by the corresponding sensing unit 51 after being pushed. The two sensing units 51 are used to determine whether to unlock and whether to lock (engage) respectively.

[0045] In this embodiment, a rotating guide 1142 protrudes from one side of the rotating member 114. The rotating guide 1142 extends in an arc shape with the rotating axis of the rotating member 114 as the center. The two ends of the rotating guide 1142 each have an inclined surface. Each sensed unit 52 is disposed on a moving seat, and the moving seat is also provided with an inclined surface. When the rotating member 114 rotates in two opposite directions, the two inclined surfaces will respectively abut against the inclined surfaces of the moving seats of the two sensed units 52, thereby pushing the moving seat and the sensed unit 52. The sensed unit 52 is preferably a magnet, and the sensing unit 51 is preferably a Hall sensor, but this is not limited to this, and the two can also be reversed.

[0046] See also Figure 2 , Figure 3 , Fig.12 and Fig.13 As shown, when the battery box 20 is installed on the base 10, the second battery engaging seat 22 at one end of the battery box 20 is first inserted into the second base engaging seat 12 of the base 10 at an angle toward the base 10, so that the side recess 221 and the top recess 222 respectively accommodate the side protrusion 121 and the top protrusion 122, and then the guide block 41 of the first battery engaging seat 21 at the other end of the battery box 20 is inserted downward into the first base engaging seat 11 along the guide groove 42 of the first base engaging seat 11.

[0047] During the insertion process, the guide block 41 in the middle of the first battery engaging seat 21 pushes against the retreating portion 1121 of the engaging member 112, causing the engaging member 112 to compress the engaging elastic component 113 and rotate until the first battery engaging seat 21 is moved to a fixed position, and the engaging elastic component 113 pushes the engaging member 112 back to its original position again to engage the first battery engaging seat 21. At this time, the recesses 221 and 222 of the second battery engaging seat 22 also completely accommodate the protrusions 121 and 122 of the second base engaging seat 12. Therefore, the second base engaging seat 12 and the first base engaging seat 11 clamp and engage the battery case 20 from two opposite directions, so that the battery case 20 cannot be separated from the base 10.

[0048] See also Figures 5 to 10 and Figures 14 to 16 As shown, when the battery box 20 is to be removed, the electronic controller 111 first rotates the rotating member 114 to rotate the engaging member 112 away from the first battery engaging seat 21, and then the separation component 115 quickly pushes the first battery engaging seat 21 away from the base (upward) until the manual unlocking member 30 (upward) abuts against the first base engaging seat 11, and then the manual unlocking member 30 is pulled again, so that the first battery engaging seat 21 can be (upward) separated from the first base engaging seat 11, and then the second battery engaging seat 22 can be tilted and separated from the second base engaging seat 12.

[0049] Preferably, in the aforementioned unlocking process, when the electronic controller 111 starts to rotate the rotating member 114, if the sensing unit 51 for determining whether to unlock senses the sensed unit 52, it will be determined that the rotating member 114 has reached the unlocking position, and the electronic controller 111 will stop rotating, and after a specific time (for example, one second), the electronic controller 111 will start to rotate the rotating member 114 in the reverse direction, and if the sensing unit 51 for determining whether to lock senses the sensed unit 52, it will be determined that the rotating member 114 has reached the locking position, and the electronic controller 111 will stop rotating. In the aforementioned process, when the electronic controller 111 starts to rotate (or rotate in the reverse direction) after a specific time (for example, two seconds), if the sensing unit 51 for determining whether to unlock (or the sensing unit 51 for determining whether to lock) does not sense the sensed unit 52, the electronic controller 111 will stop rotating. The use of the sensing unit 51 and the sensed unit 52 is not limited to the above.

[0050] The utility model can therefore lock the battery box 20 to prevent theft, and at the same time, the battery box 20 and the base 10 can be unlocked through an electronic controller (such as through a mobile phone APP) without using or carrying a key, so that the battery box 20 can be removed for easy use.

[0051] The above description of the utility model is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any person with ordinary knowledge in the technical field can make some changes or modify the technical contents disclosed above into equivalent embodiments of equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still fall within the scope of the technical solution of the utility model.
