Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shared power banks, and in particular to a motor lock and a bin body assembly. BACKGROUND

[0002] Power bank rental equipment aims to provide users with convenient charging services. Power bank rental equipment is arranged in many public places, such as restaurants, hotels, airports, and stations. Users can rent a power bank from the power bank rental equipment by scanning a code and use it, and then return it after use, which provides great convenience for people and solves the problem of insufficient power of electrical appliances when people go out.

[0003] The power bank rental equipment generally includes a charging bin, a power bank, and a locking mechanism. The power bank is located in the charging bin, and the locking mechanism is used to lock / unlock the power bank in the charging bin. At present, the locking mechanism in the existing power bank rental equipment is configured as an electromagnet, which controls the extension distance of the movable iron core in the electromagnet to lock / unlock the power bank in the charging bin. Alternatively, the locking mechanism is configured as a motor lock, which controls the stroke of a lock tongue by using a motor to lock / unlock the power bank in the charging bin. However, in the above two methods, one locking mechanism can only control the locking / unlocking of one corresponding power bank. Therefore, each power bank in the charging bin needs to be equipped with a locking mechanism to lock / unlock the corresponding power bank. This increases the overall production cost of the power bank rental equipment, and also makes the overall volume of the power bank rental equipment large and reduces the effective use space of the power bank rental equipment.

DETAILED DESCRIPTION

[0047] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, the detailed description of the specific embodiments of the present application is made below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways from those described herein without departing from the scope of the present application. It is therefore intended that the present application is not limited by the specific embodiments disclosed below.

[0048] It is to be noted that when an element or layer is referred to as being "on" or "connected to" another element or layer, it can be directly on or connected to the other element or layer, or intervening elements or layers can be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements or layers present. The use of the terms "on" and "connected to" in the present description are to be construed in the broadest sense and can include over, under, or adjacent.

[0049] In addition, the terms "first", "second", etc. are used herein only to describe various elements, but do not imply or suggest relative importance or a quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0050] In the present application, unless otherwise explicitly specified and limited, "on", "under", and "below" of a first feature to a second feature can be that the first feature is directly in contact with the second feature, or the first feature is indirectly in contact with the second feature through an intermediate medium. Moreover, "over", "above", and "on top of" of a first feature to a second feature can be that the first feature is directly above or obliquely above the second feature, or only means that the first feature is horizontally higher than the second feature. "Under", "below", and "underneath" of a first feature to a second feature can be that the first feature is directly below or obliquely below the second feature, or only means that the first feature is horizontally lower than the second feature.

[0051] Unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the associated listed items.

[0052] The motor lock 100 claimed in the present application can be applied to a power bank leasing device to lock / unlock the power bank 200 in the bin body 300 of the power bank leasing device. Of course, the motor lock 100 is not limited to be applied to the power bank leasing device, but can also be applied to other sharing devices, such as the sharing device can be used to charge the battery.

[0053] As shown in Figures 1 to 18 , the motor lock 100 provided by an embodiment of the present application comprises a motor 30, a rotating disc assembly 40 and a locking assembly. The rotating disc assembly 40 is in transmission connection with the motor 30. The rotating disc assembly 40 comprises a first rotating disc 41 and a second rotating disc 42. The second rotating disc 42 is sleeved on the first rotating disc 41 in a circumferential limiting manner and is in sliding connection with the first rotating disc 41. The locking assembly comprises two locking elements 21. The two locking elements 21 are arranged on two opposite sides of the first rotating disc 41 in a sliding manner. Each locking element 21 can move between a locking position and an unlocking position. Each locking element 21 can be driven by the second rotating disc 42 to move from the locking position to the unlocking position after sliding. The motor 30 has a stop state and a working state. In the stop state, the two locking elements 21 are in the locking position. In the working state, one of the two locking elements 21 is in the locking position and the other is in the unlocking position.

[0054] It can be understood that when the motor lock 100 of the present application is applied to the power bank leasing device and works, the two locking elements 21 can be alternately unlocked by controlling the forward and reverse rotation of the motor shaft 31 of the motor 30. Thus, the motor lock 100 can realize the control of unlocking / locking of the two power banks 200 in the bin body 300 of the power bank leasing device by using one motor 30. In this way, the number of motors 30 required in the power bank leasing device can be reduced. On the one hand, the overall production cost of the power bank leasing device can be reduced. On the other hand, the overall volume of the power bank leasing device can be reduced due to the reduction of the number of motors 30, so that the effective use space of the power bank leasing device can be improved.

[0055] In an embodiment, as shown in Figure 1 , the motor lock 100 comprises a housing 10. The two locking elements 21 are slidably mounted in the housing 10. Here, each locking element 21 can slide a preset stroke towards the center line of the housing 10 to realize the locking / unlocking of each locking element 21.

[0056] In an embodiment, as shown in Figure 1As shown, the shell 10 comprises a first shell 11 and a second shell 12, and the assembly connection between the first shell 11 and the second shell 12 can be achieved by screwing between the connecting piece 50 passing through the first shell 11 and the second shell 12. Here, the connecting piece 50 can be set as a self-tapping screw, a bolt, etc.

[0057] In an embodiment, as shown in Figure 3 The locking element 21 further comprises a sliding plate 213, and the locking element 21 can be slidably connected with the shell 10 through the sliding plate 213, so as to achieve the sliding assembly of the locking element 21 on and between the shell 10.

[0058] In an embodiment, as shown in Figure 3 , Figure 4 The second rotating disc 42 is provided with a groove 422, and the outer circumferential surface of the first rotating disc 41 is provided with a convex rib 412 corresponding to the groove 422, and the convex rib 412 can be inserted and connected with the corresponding groove 422, so as to limit the second rotating disc 42 on the first rotating disc 41 in the circumferential direction; wherein the second rotating disc can slide relative to the first rotating disc 41 along the length direction of the convex rib 412. In other embodiments, a groove can also be formed on the outer circumferential surface of the first rotating disc 41 (not shown in the figure), and a convex rib (not shown in the figure) can be arranged on the inner circumferential surface of the second rotating disc 42, which will not be described here.

[0059] In an embodiment, as shown in Figures 3 to 5 The inner side of the first rotating disc 41 is provided with a first groove 411, and the outer circumferential surface of the motor shaft 31 is provided with a first convex rib 311 corresponding to the first groove 411, and the first convex rib 311 can be inserted and connected with the corresponding first groove 411, so as to limit the first rotating disc 41 on the motor 30 in the circumferential direction, so that the first rotating disc 41 can rotate with the motor shaft 31 of the motor 30.

[0060] In an embodiment, as shown in Figure 4 The second rotating disc 42 is provided with two pushing blocks 421 arranged on the upper and lower sides of the second rotating disc 42 and corresponding to the two locking elements 21; in the working state of the motor 30, one of the pushing blocks 421 can drive the second rotating disc 42 to slide on the first rotating disc 41 under the pushing of the corresponding locking element 21, so that the second rotating disc 42 after sliding can push and unlock the other locking element 21 through the other pushing block 421.

[0061] In an embodiment, as shown in Figure 4As shown in the figure, one end face of each pushing block 421 is configured as a pushing inclined surface, and the pushing block 421 can abut against the corresponding locking element 21 through the pushing inclined surface, for driving the second rotating disc 42 to slide on the first rotating disc 41. In this way, the use requirement that the pushing block 421 can drive the second rotating disc 42 to slide on the first rotating disc 41 under the pushing of the corresponding locking element 21 can be met.

[0062] In an embodiment, as shown in the figure, Figure 4 the other end face of each pushing block 421 is configured as a pushing flat surface, and the pushing block 421 can abut against the corresponding locking element 21 through the pushing flat surface, for driving the corresponding locking element 21 to be unlocked.

[0063] In an embodiment, as shown in the figure, Figure 3 , Figure 4 , Figure 8 The pushing block 421 located below the second rotating disc 42 is set as the first pushing block 4213, the locking element 21 that can be unlocked under the driving of the first pushing block 4213 is set as the second locking element 214, the second locking element 214 is formed with a pushing matching block 2141, and the second locking element 214 can abut against the first pushing block 4213 through the pushing matching block 2141; wherein the pushing matching block 2141 is provided with an empty slot 21411 for avoiding the first pushing block 4213, so that the first pushing block 4213 can rotate relative to the pushing matching block 2141 through the empty slot 21411. It should be noted that, since the pushing matching block 2141 linearly slides in the housing 10, and the first pushing block 4213 rotates in the housing 10, the first pushing block 4213 and the pushing matching block 2141 will gradually dislocate until completely separated during the process of the first pushing block 4213 pushing the pushing matching block 2141. Here, the pushing block 421 located above the second rotating disc 42 is set as the second pushing block 4214, and the locking element 21 that can be unlocked under the driving of the second pushing block 4214 is set as the first locking element 215.

[0064] As preferred, as shown in the figure, Figure 4 one end face of the second pushing block 4214, which can abut against the first locking element 215 through the pushing inclined surface, is configured as a second pushing inclined surface 42141, and correspondingly, one end face of the first pushing block 4213, which can drive the second locking element 214 to be unlocked through the pushing flat surface, is configured as a first pushing flat surface 42132; one end face of the first pushing block 4213, which can abut against the second locking element 214 through the pushing inclined surface, is configured as a first pushing inclined surface 42131, and correspondingly, one end face of the second pushing block 4214, which can drive the first locking element 215 to be unlocked through the pushing flat surface, is configured as a second pushing flat surface 42142.

[0065] In one embodiment, such as Figure 2 , Figure 6 The locking assembly also includes an elastic element 22, which is pre-compressed and assembled between the two locking elements 21. Utilizing the elastic deformation of the elastic element 22, the two locking elements 21 can automatically extend from the housing 10 without being pushed by the second turntable 42, thus meeting the need to lock the power bank 200 using the locking elements 21. In other words, when the motor lock 100 is working, the motor 30 controls the second turntable 42 to rotate within the housing 10, and then uses the push block 421 on the second turntable 42 and the elastic element 22 to push against the corresponding locking elements 21, thereby controlling the corresponding locking elements 21 to slide back and forth on the housing 10, and achieving control over the locking elements 21 to unlock / lock the corresponding power bank 200. Here, the elastic element 22 is set as a spring; in other embodiments, the elastic element 22 can also be set as a rubber sleeve or other highly elastic object.

[0066] In one embodiment, such as Figure 2 As shown, one of the two locking elements 21 has a first limiting portion 211, and the other has a second limiting portion 212. The first limiting portion 211 and the second limiting portion 212 can be inserted into the elastic member 22 to limit the elastic member 22. This facilitates the assembly of the elastic member 22 between the two locking elements 21 and ensures the stability of the elastic member 22 during assembly between the two locking elements 21. Here, both the first limiting portion 211 and the second limiting portion 212 are configured as positioning protrusions that can be inserted into both ends of the elastic member 22; of course, those skilled in the art can also configure the first limiting portion 211 and / or the second limiting portion 212 as grooves that match both ends of the elastic member 22. Preferably, the two locking elements 21 are a first locking element 215 and a second locking element 214, respectively. A first limiting portion 211 is formed on the first locking element 215, and a second limiting portion 212 is formed on the second locking element 214. Of course, in other embodiments, the first limiting portion 211 may be formed on the second locking element 214, and the second limiting portion 212 may be formed on the first locking element 215, which will not be elaborated here.

[0067] The working principle of the motor lock 100 in this application is as follows: Figure 6For the initial position of the motor lock 100, when the motor shaft 31 of the motor 30 rotates forward (clockwise), the motor shaft 31 of the motor 30 drives the second turntable 42 to rotate in the housing 10 through the first turntable 41, and in the process, the second push block 4214 on the second turntable 42 first abuts against the third push inclined surface 2151 on the first locking element 215, the second turntable 42 continues to rotate, and by using the action and reaction force, the downward sliding of the second turntable 42 on the first turntable 41 can be realized, until the second push inclined surface 42141 of the second push block 4214 is separated from the third push inclined surface 2151 on the first locking element 215, and specifically as shown in Figure 7 , the second turntable 42 stops sliding, and then the second turntable 42 continues to rotate, the first push flat surface 42132 on the first push block 4213 can push the push fitting block 2141 of the second locking element 214, and the second locking element 214 can compress the elastic member 22 and be unlocked under the push of the push fitting block 2141, and specifically as shown in Figure 8 , so that the second locking element 214 can release the locking of the power bank 200, when the second turntable 42 continues to rotate, the first push flat surface 42132 will be separated from the push fitting block 2141, and the push of the second locking element 214 will be lost, so that the second locking element 214 is reset under the elastic push of the elastic member 22; when the motor shaft 31 of the motor 30 rotates reversely (counterclockwise), the motor shaft 31 of the motor 30 drives the second turntable 42 to rotate in the housing 10 through the first turntable 41, and in the process, the first push inclined surface 42131 of the first push block 4213 on the second turntable 42 first abuts against the fourth push inclined surface 2142 on the second locking element 214, the second turntable 42 continues to rotate, and by using the action and reaction force, the upward sliding of the second turntable 42 on the first turntable 41 can be realized, until the first push inclined surface 42131 of the first push block 4213 is separated from the fourth push inclined surface 2142 of the second locking element 214, the second turntable 42 stops sliding, and then the second turntable 42 continues to rotate, the second push flat surface 42142 on the second push block 4214 can push the push part 2152 of the first locking element 215, and the first locking element 215 can compress the elastic member 22 and be unlocked under the push of the push part 2152, so that the first locking element 215 can release the locking of the power bank 200, when the second turntable 42 continues to rotate, the second push flat surface 42142 will be separated from the push part 2152, and the push of the first locking element 215 will be lost, so that the first locking element 215 is reset under the elastic push of the elastic member 22.

[0068] The application also claims a warehouse body assembly 1 comprising the warehouse main body 300 and the motor lock 100; the warehouse main body 300 comprises two rows of warehouse bodies 301, and the motor lock 100 is arranged between two warehouse bodies 301 in the two rows of warehouse bodies 301; wherein each warehouse body 301 is used for accommodating a power bank 200. Here, the number of warehouse bodies 301 in the warehouse main body 300 is 6, and the number of corresponding motor locks 100 is 3; of course, in other embodiments, the number of warehouse bodies 301 in the warehouse main body 300 can also be 2, 4, 8 or even more, which will not be described here.

[0069] As shown in FIG. 9, in an embodiment, the assembly connection between the motor lock 100 and the warehouse main body 300 can be achieved by screwing through the bolt 600 between the shell 10 and the warehouse main body 300.

[0070] In an embodiment, as shown in FIG. Figure 15 The locking element 21 has a lock tongue 216, which can pass through the corresponding warehouse body 301 and be clamped with the power bank 200 in the warehouse body 301, for locking the power bank 200 in the warehouse body 301; wherein the first detection sensor 503 is arranged on each warehouse body 301, which can detect the retraction of the corresponding lock tongue 216 and generate a feedback signal, and the motor 30 can stop the rotation of the first turntable 41 according to the feedback signal. Here, the first detection sensor 503 is a photoelectric sensor, a laser sensor, etc. It should be noted that in the initial state, the power bank 200 in the warehouse body 301 will be locked by the lock tongue 216 on the locking element 21. Since the extension and retraction of the locking element 21 on the shell 10 is controlled by the motor 30 independently, and the operation of the motor 30 will not be affected by the external environment, it can avoid the situation of stealing the power bank when the power bank leasing device is used.

[0071] In an embodiment, as shown in FIG. Figure 9 , Figure 11 The warehouse body assembly 1 further comprises a slave board 500, which is installed on the warehouse main body 300 and used for charging the power bank 200 in the warehouse body 301; the number of slave boards 500 is one, and the slave board 500 can supply power to all power banks 200 in the warehouse body 301. Here, the assembly connection between the slave board 500 and the warehouse main body 300 can be achieved by screwing through the screw 510 between the slave board 500 and the warehouse main body 300. It should be noted that the first detection sensor 503 is integrated on the slave board 500 and arranged correspondingly with the locking element 21.

[0072] In an embodiment, as shown in FIG. Figure 10 , Figure 11As shown, a plurality of position switch sensors 501 are also integrated on the control board 500, the plurality of position switch sensors 501 are arranged one-to-one with the power banks 200 in the plurality of storage bodies 301, for judging whether there is a power bank 200 in the corresponding storage body 301.

At this time, the information of the power bank 200 can be read by the pogo pin 502 on the slave board 500 and the power bank 200 can be charged. In this process, the position switch sensor 501 on the slave board 500 can determine whether there is a power bank 200 in the corresponding bin body 301. The first detection sensor 503 on the bin body 301 is re-occluded by the second locking element 214, and the second locking element 214 is used to determine that the power bank 200 is locked. When the user rents the power bank 200, the user can scan the code (not shown in the figure) on the power bank rental equipment to trigger the slave board 500. The slave board 500 controls the motor 30 in the motor lock 100 corresponding to the bin body 301 to start. The motor shaft 31 of the motor 30 rotates forward (clockwise), and the second turntable 42 is driven by the first turntable 41 to rotate in the shell 10. The second locking element 214 can compress the elastic member 22 and be unlocked under the driving of the second turntable 42. The locking tongue 216 leaves the clamping groove 201 of the power bank 200, and the power bank 200 is pushed out of the bin body 301 by using the push rod 402 to elastically push the power bank 200. Details can be seen from the following figure. Figure 18 As shown, the user can extract the power bank 200. Then, the second locking element 214 is reset under the elastic push of the elastic member 22, and the first detection sensor 503 on the bin body 301 is completely occluded by the second locking element 214. Details can be seen from the following figure. ​ As shown, finally, the slave board 500 algorithm controls, and the motor lock 100 is reset to the initial position.

[0076] It should be noted that the principle of how the motor lock 100 controls the unlocking / locking of the right power bank 200 in the bin body 300 can refer to the principle of how the motor lock 100 controls the unlocking / locking of the left power bank 200 in the bin body 300 as described above, which will not be repeated here.
