Description

[Technical Field]

[0001] The present invention relates to the technical field of rental of shared mobile batteries, and in particular to a locking mechanism, a charging module, and a shared device. [Background technology]

[0002] In a shared mobile battery rental system, the mobile battery is typically locked to a mounting bracket and removed from the mounting bracket when rental is required.

[0003] Conventional locking methods include combining a locking mechanism with a pop-up mechanism to lock and pop up a mobile battery, but because the physical structure requires multiple components to be interlocked, the interlocking requirements between the components are high, the overall structure is complex, and the operation is prone to jamming.Furthermore, if one function fails, the other function is also disabled, making maintenance cumbersome.

[0004] Another solution is to separate the locking mechanism and the pop-up mechanism and use a single locking mechanism to lock the mobile battery. For example, a solenoid valve is used to lock the mobile battery. Specifically, the solenoid valve pops up a latch, which is then inserted into the mobile battery's engaging groove to lock the mobile battery. However, if the mobile battery is forcibly pulled, the pulling force acts directly on the latch, which is likely to damage the solenoid valve and result in poor stability. Another solution is to use a stepping motor to rotate the locking arm. Specifically, the stepping motor drives the locking arm to rotate forward and backward to a predetermined angle, inserting the locking arm into or disengaging it from the engaging groove of the mobile battery, and utilizing the self-locking function of the stepping motor to lock the rotation angle of the locking arm. However, this solution requires high control over the rotation angle of the locking arm, making it impossible to replace the stepping motor with a conventional motor. The stepping motor is expensive and bulky, making it difficult to miniaturize the locking structure. Summary of the Invention

[0005] To overcome at least one of the deficiencies described in the prior art, the present invention provides a locking mechanism in which a motor drives an eccentric wheel to rotate and swing a swinging member, thereby retracting the key cylinder from the through-hole and unlocking the mobile battery, and the elastic force of an elastic member drives the swinging member to return, causing the key cylinder to protrude from the through-hole and locking the mobile battery. This locking mechanism is stable, low cost, small in volume, and easy to maintain.

[0006] The technical solution adopted to solve the problems of the present invention is a locking mechanism comprising: a case having a mounting cavity and a through hole communicating with the mounting cavity; a swinging member rotatably arranged within the mounting cavity of the case and having a key cylinder with an engagement groove for insertion into a mobile battery to lock it; a motor arranged in the case and having an eccentric wheel attached to an output shaft, the eccentric wheel abutting against the swinging member to drive the swinging member to swing and retract the key cylinder from the through hole; and an elastic member arranged between the case and the swinging member to provide a restoring elastic force to the swinging member and cause the key cylinder to protrude from the through hole.

[0007] In the locking mechanism provided by the present invention, when the mobile battery is returned, the mobile battery presses the key cylinder against it, driving the swinging member, which swings in the opposite direction against the elastic force of the elastic member, retracting the key cylinder from the through-hole. After the engagement groove of the mobile battery and the key cylinder are aligned, the elastic force of the elastic member drives the swinging member to swing in the forward direction and return, causing the key cylinder to protrude from the through-hole and be inserted into the engagement groove of the mobile battery, locking it. When the swinging member is driven to swing in the opposite direction in the absence of external force, the key cylinder and the engagement groove cannot be disengaged, keeping the mobile battery locked. When the mobile battery is removed, the motor drives the eccentric wheel to rotate, and the eccentric wheel abuts against the swinging member, driving the swinging member to swing in the opposite direction, retracting the key cylinder from the through-hole and disengaging it from the engagement groove of the mobile battery, thereby unlocking the mobile battery.

[0008] In the above technical solution, the motor drives the eccentric wheel to rotate and swing the oscillating member, thereby unlocking the mobile battery; the elastic force of the elastic member drives the oscillating member to return to its original position, thereby locking the mobile battery; when the mobile battery is forcibly pulled, the tensile force acts on the circumferential side of the key cylinder and is transmitted to the rotation axis of the oscillating member, without affecting the motor; at the same time, the motor and eccentric wheel are combined to unlock the mobile battery, and because the requirements for the rotation angle of the eccentric wheel are low, the motor does not need to precisely control the rotation angle of the eccentric wheel; the requirements for motor performance are low, and a general motor which is cheap, small, and has a small volume can be used as the power source; the combination of the above structures improves the stability of the locking mechanism, and the overall cost is low, the volume is small, and it is easy to maintain.

[0009] Furthermore, the swinging member is integral with the key cylinder.

[0010] Furthermore, the swinging member is configured as a separate body from the key cylinder, which prevents the mobile battery from being easily pulled out when it is locked.

[0011] Furthermore, when the swinging member and the key cylinder are configured separately, the device further includes a locking member, which includes a locking member key cylinder configured as an integral unit, a storage section, and a locking member insertion post, the key cylinder and the insertion post being located on both sides of the storage section, the elastic member being a spring and fitted onto the insertion post, and one end of the swinging member being inserted into the storage section, so that when the eccentric wheel drives the swinging member to swing, the swinging member can retract the key cylinder of the locking member from the through-hole, and the elastic member provides a restoring elastic force to the swinging member via the locking member, causing the key cylinder to protrude from the through-hole.

[0012] Furthermore, the device further includes a detection element, which is configured to detect the swinging state of the swinging member to identify the movement status of the swinging member, and further determine whether there is an unlocking operation or whether the return of the mobile battery is successful.

[0013] Furthermore, the detection element is a first detection switch, which is provided in the case and located on one side of the swingable member, the eccentric wheel drives the swingable member to swing so as to press the first detection switch, and the elastic member drives the swingable member to return to its original position and release the first detection switch. In this way, detecting the swing state of the swingable member by using the power on / off of the first detection switch is based on a simple principle, has a simple overall structure, and is low cost.

[0014] Furthermore, the first detection switch and the key cylinder are located on either side of the rotation axis of the swing member.

[0015] Furthermore, two oscillating members are provided, and the two oscillating members are arranged side by side along the direction of their rotation axes. One motor is provided and is located between the two oscillating members. The motor selectively drives the two oscillating members via an eccentric wheel. In this way, the two oscillating members can respectively lock different mobile batteries, and the two oscillating members can be driven by only one set of motor and eccentric wheel, further reducing costs.

[0016] Furthermore, the rocking members are provided with abutment bases for abutting against the eccentric rings, and the abutment bases of the two rocking members extend in directions approaching each other.

[0017] The case further includes a front case and a rear cover. The front case is provided with a first mounting groove, two second mounting grooves, and one conductive groove. The two second mounting grooves are located on opposite sides of the first mounting groove, and the conductive groove provides electrical connection between the first mounting groove and the two second mounting grooves. The two oscillating members are rotatably mounted in different second mounting grooves, and the abutment bases of the two oscillating members both extend into the conductive grooves. The motor is mounted in the first mounting groove, and the eccentric wheel is located in the conductive groove to abut against the abutment base. In this way, the motor, eccentric wheel, and two oscillating members can be mounted with a compact overall layout and accurate mounting position.

[0018] Furthermore, the key cylinder and the elastic member are located on opposite sides of the swinging member.

[0019] Furthermore, the swinging member is provided with an insertion post, and the elastic member is a spring that is fitted onto the insertion post, thereby preventing the elastic member from loosening.

[0020] Furthermore, a guide surface is provided on the key cylinder, and when the mobile battery is returned, the side of the mobile battery abuts against the guide surface, allowing the key cylinder to be more easily retracted.

[0021] Based on a similar idea, the present invention further discloses a charging module used for renting and returning storage of mobile batteries, comprising a mounting bracket, an extrusion mechanism, and the above-mentioned locking mechanism, wherein the mounting bracket is provided with a receiving cavity having an outlet end for receiving the mobile battery, the extrusion mechanism is provided on the mounting bracket for pushing the mobile battery to protrude from the outlet end, and the locking mechanism is provided on the mounting bracket for locking or unlocking the mobile battery.

[0022] The device further includes a verification module for detecting the identification information of the mobile battery. The verification module may be used to determine whether the returned mobile battery is authentic or whether the mobile battery is housed in the housing cavity, and in combination with the locking determination of the locking mechanism, this avoids a false return determination caused by only completing a part of the returning operation of the mobile battery but ultimately pulling out the mobile battery.

[0023] The device further includes a second detection switch provided on one side wall away from the outlet end of the receiving cavity for contacting an end of the mobile battery. Similarly, the second detection switch may be used to determine whether the mobile battery is received in the receiving cavity, and in combination with the lock determination of the locking mechanism, this avoids a false return determination that occurs after only completing a partial return operation of the mobile battery but ultimately withdrawing the mobile battery.

[0024] Based on a similar idea, the present invention further discloses a shared device to which the above-mentioned charging module is applied.

[0025] As described above, the locking mechanism according to the present invention has the following technical effects.

[0026]

[0013] The motor drives the eccentric wheel to rotate, causing the oscillating member to oscillate, thereby unlocking the mobile battery; the elastic force of the elastic member drives the oscillating member to return, thereby locking the mobile battery; when the mobile battery is forcibly pulled, the tensile force acts on the circumferential side of the key cylinder and is transmitted to the rotation axis of the oscillating member, without affecting the motor; at the same time, because the motor is used in combination with the eccentric wheel to unlock the mobile battery and the requirements for the rotation angle of the eccentric wheel are low, the motor does not need to precisely control the rotation angle of the eccentric wheel, and the requirements for motor performance are low; the combination of the above structures improves the stability of the locking mechanism, and the overall cost is low, the volume is small, and at the same time, it is easy to maintain. Other beneficial effects of the present invention will be disclosed in the specific embodiments. [Brief explanation of the drawings]

[0028] For better understanding and implementation, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention.

[0029] In describing the present invention, orientations or positional relationships indicated by terms such as "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are based on orientations or positional relationships shown in the drawings, and are merely for the convenience and simplification of the description of the present invention. They do not indicate or imply that the devices or elements shown must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terms used herein are used only for the purpose of describing specific examples and are not intended to limit the present application.

[0031] Example 1 Referring to Figures 1 to 3, this embodiment discloses a locking mechanism 1, which is used to lock or unlock a mobile battery, and includes a case 11, a swinging member 12, a motor 13, an eccentric wheel 14, an elastic member 15, and a detection element 16.

[0032] The case 11 has a mounting cavity 113 as a mounting portion and a through hole 114 that communicates with the mounting cavity 113. Specifically, the case 11 includes a front case 111 and a rear cover 112, which are connected by engagement or bolts, forming the mounting cavity 113 between the front case 111 and the rear cover 112, and the through hole 114 passes through the front case 111 and communicates with the mounting cavity 113.

[0033] The swinging member 12 is rotatably provided in the mounting cavity 113 of the case 11 as a locking part, and is provided with a key cylinder 121 for insertion into an engagement groove of the mobile battery to lock it, the key cylinder 121 retracts or protrudes in the through hole 114, and when the key cylinder 121 retracts, it can be released from the engagement groove of the mobile battery, and when the key cylinder 121 protrudes, it can be inserted into the engagement groove of the mobile battery to lock it. The swinging member 12 is configured integrally with the key cylinder 121.

[0034] Motor 13 is provided in case 11 as an actively controllable power source, and more specifically, motor 13 is similarly located within mounting cavity 113. Eccentric wheel 14 is attached to the output shaft of motor 13 as a transmission unit, and is positioned so that eccentric wheel 14 abuts against swinging member 12 to drive the swinging of swinging member 12, thereby retracting key cylinder 121 from through-hole 114.

[0035] The elastic member 15 is provided between the case and the swinging member as a passive power source, and specifically, the elastic member 15 is also located within the mounting cavity 113. The elastic member 15 provides a restoring elastic force to the swinging member 12, causing the key cylinder 121 to protrude from the through-hole 114.

[0036] In the locking mechanism 1 provided by the present invention, when the mobile battery is returned, the mobile battery presses the key cylinder 121 to drive the swinging member 12, which swings in the opposite direction against the elastic force of the elastic member 15, retracting the key cylinder 121 from the through-hole 114, and after the engagement groove of the mobile battery and the key cylinder 121 are aligned, the elastic force of the elastic member 15 drives the swinging member 12 to swing back in the forward direction, causing the key cylinder 121 to protrude from the through-hole 114 and be inserted into the engagement groove of the mobile battery to lock it, and when the swinging member 12 is driven to swing in the opposite direction in the absence of external force, the key cylinder 121 cannot disengage from the engagement groove, and the mobile battery remains locked. When the mobile battery is removed, the motor 13 drives the rotation of the eccentric wheel 14, and the eccentric wheel 14 abuts against the swinging member 12, driving the swinging member 12 to swing in the opposite direction, causing the key cylinder 121 to retreat from the through-hole 114 and disengage from the engagement groove of the mobile battery, thereby unlocking the mobile battery.

[0037] In the above technical solution, the motor 13 drives the rotation of the eccentric wheel 14 to swing the swinging member 12, thereby unlocking the mobile battery, and the elastic force of the elastic member 15 drives the swinging member 12 to return to its original position, thereby locking the mobile battery. When the mobile battery is forcibly pulled, the tensile force acts on the circumferential side of the key cylinder 121 and is transmitted to the rotation axis of the swinging member 12 (specifically, due to the relative design of the position of the rotation axis of the swinging member 12 in general means and the position of the force point when the key cylinder 121 locks the mobile battery, the connection line between the rotation axis of the swinging member 12 and the force point of the key cylinder 121 is approximately parallel to or slightly inclined with the direction of the tensile force. By controlling the deviation, the largest part of the stress caused by the tensile force acts on the rotation axis of the swinging member 12, and only a small stress acts in the direction of rotation of the swinging member 12 to release it. In either case, the motor 1 3 has the effect of releasing the swinging member 12, and the stress caused by this tensile force does not affect the motor 13), and the combination of the motor 13 and eccentric wheel 14 is used to unlock the mobile battery, and the requirements for the rotation angle of the eccentric wheel 14 are low (when the eccentric wheel 14 rotates until its highest point abuts the swinging member 12, any deviation in the rotation angle of the eccentric wheel 14 to the left or right has little effect on the swing angle of the swinging member 12). Therefore, the motor 13 does not need to precisely control the rotation angle of the eccentric wheel 14, and the requirements for the performance of the motor 13 are low, so a general motor which is inexpensive and small in volume can be used as the power source. The combination of the above structures improves the stability of the locking mechanism 1, and the overall cost is low, the volume is small, and maintenance is easy.

[0038] Referring to FIG. 3, specifically, the rocker member 12 is hingedly connected within the mounting cavity 113 of the case 11 to form a seesaw structure, the key cylinder 121 is located at a first end of the rocker member 12, the eccentric wheel 14 abuts against a second end of the rocker member 12, and the rotation axis of the rocker member 12 is located between both ends of the rocker member 12 (i.e., the rotation axis of the rocker member 12 is basically located at the middle position of the rocker member 12. Of course, the rotation axis of the rocker member 12 may be offset toward the first end of the rocker member 12, or the rotation axis of the rocker member 12 may be offset toward the second end of the rocker member 12).

[0039] Here, the key cylinder 121 and the eccentric wheel 14 are respectively positioned on opposite sides of the swinging member 12, and the key cylinder 121 and the elastic member 15 are similarly respectively positioned on opposite sides of the swinging member 12, and the eccentric wheel 14 and the elastic member 15 are positioned on the same side of the swinging member 12, thereby preventing the eccentric wheel 14 and the elastic member 15 from occupying space on the key cylinder 121 side.

[0040] 4, preferably, a contact base 122 is provided on the swinging member 12, and the contact base 122 is used to contact the eccentric wheel 14. Specifically, the contact base 122 is located at the second end of the swinging member 12, and after the motor 13 drives the rotation of the eccentric wheel 14, the eccentric wheel 14 gradually contacts the contact base 122, pressing against and rotating the swinging member 12 via the contact base 122, thereby retracting the key cylinder 121.

[0041] 2, an insertion post 123 is preferably provided on the swinging member 12, and the elastic member 15 is a spring fitted onto the insertion post 123 to restrict the elastic member 15 and prevent it from loosening. Specifically, the key cylinder 121 and the insertion post 123 are located on opposite sides of the swinging member 12 and extend away from each other, and an abutment block 1121 is provided on the rear cover 112 on the side facing the front case 111, with one end of the elastic member 15 fitted onto the insertion post 123 and the other end of the elastic member 15 abutting against the abutment block 1121.

[0042] Preferably, in this embodiment, in order to make it easier to push in and retract the key cylinder 121 when returning the mobile battery, a guide surface 1211 is provided on the key cylinder 121, and when returning the mobile battery, the side of the mobile battery abuts against the guide surface 1211, and as the mobile battery moves further, the key cylinder 121 retracts until the key cylinder 121 is inserted into the engagement groove of the mobile battery and locked, and the abutment surface between the key cylinder 121 and the mobile battery gradually moves from the guide surface 1211 to the end surface of the key cylinder 121.

[0043] 2 and 3, in this embodiment, taking into account the deviations in the movement of each component or the assembly process, the detection element 16 is configured to detect the movement state of the rocking member 12 to identify the movement state of the rocking member 12. Specifically, the detection element 16 can determine whether an unlocking operation has occurred or whether the mobile battery has been successfully returned by detecting whether the motor 13 drives the rocking member 12 and whether the rocking member 12 has been successfully reset. In particular, if the detection element 16 determines that the rocking member 12 has not been successfully reset, it indicates that the mobile battery is in a provisional engagement state and is determined to have failed to be returned, whereby the system will alert the user or provide background feedback.

[0044] Specifically, the detection element 16 is a first detection switch, which is provided in the case 11 and located on one side of the swinging member 12, the eccentric wheel 14 drives the swinging of the swinging member 12 so as to press the first detection switch, and the elastic member 15 drives the swinging member 12 to return and release the first detection switch. In this way, detecting the swinging state of the swinging member 12 by using the on / off of the power supply to the first detection switch is a simple principle, has a simple overall configuration, and is low cost.

[0045] 2 and 4, in this embodiment, two rocking members 12 are provided, and the two rocking members 12 are arranged side by side along the direction of their rotation axes. One motor 13 is provided, located between the two rocking members 12, and the motor 13 selectively drives one of the two rocking members 12 via an eccentric wheel 14. When in use, each rocking member 12 can lock one mobile battery. When the first rocking member 12, i.e., the right rocking member 12 shown in FIG. 4, needs to be used, the motor 13 drives the eccentric wheel 14 to rotate clockwise, and the eccentric wheel 14 abuts against the abutment base 122 of the right rocking member 12, driving the right rocking member 12 to rotate and retract the key cylinder 121 thereon. When it is necessary to use the second swing member 12, i.e., the left swing member 12 shown in FIG. 4, the motor 13 drives the eccentric wheel 14 to rotate it counterclockwise, and the eccentric wheel 14 abuts against the abutment base 122 of the left swing member 12, driving the left swing member 12 to rotate and retract the key cylinder 121 above it.

[0046] In this way, the two oscillating members 12 can each lock a different mobile battery, allowing the locking mechanism 1 to lock two mobile batteries, and driving the two oscillating members 12 can be achieved using only one set of motor 13 and eccentric wheel 14, further reducing costs.

[0047] Based on the same idea, two detection elements 16 are similarly provided, each corresponding to a respective swinging member 12 , and specifically, the detection elements 16 are located on the opposite side of the abutment base 122 from the eccentric wheel 14 .

[0048] Preferably, the two detection elements 16 are attached to a mounting plate 161, which is attached to the outer surface of the front case 111, and the front case 111 is provided with a detection hole (not shown) that passes through to the mounting cavity 113, and the detection elements 16 are inserted into the mounting cavity 113 through the detection hole, thereby facilitating the attachment, detachment, and inspection of the two detection elements 16.

[0049] Based on the idea of ​​installing the two oscillating members 12 described above, it is preferable that the abutment bases 122 of the two oscillating members 12 extend in a direction approaching each other, so that the eccentric wheel 14 can more easily switch between abutment with each of the two abutment bases 122, and prevent the eccentric wheel 14 from rotating excessively and becoming trapped between the two abutment bases 122.

[0050] 5 and 6, in order to mount each component to the case, in this embodiment, the front case 111 is provided with one first mounting groove 1111, two second mounting grooves 1112, and one conductive groove 1113, each groove being substantially rectangular. The two second mounting grooves 1112 are located on opposite sides of the first mounting groove 1111, and the conductive groove 1113 serves as a guide for the first mounting groove 1111 and the two second mounting grooves 1112. The two oscillating members 12 are rotatably mounted in different second mounting grooves 1112, and the abutment bases 122 of the two oscillating members 12 both extend into the conductive grooves 1113. The motor 13 is mounted in the first mounting groove 1111, and the eccentric wheel 14 is located in the conductive groove 1113 to abut against the abutment base 122. In this way, the mounting of the motor 13, eccentric wheel 14 and two oscillating members 12 is realized, and the overall structure is compact and the mounting position is accurate.

[0051] Specifically, the first mounting groove 1111 is arranged parallel to the second mounting groove 1112, the conductive groove 1113 is arranged perpendicular to the first mounting groove 1111 and the second mounting groove 1112, the through hole 114 is connected to the second mounting groove 1112, and the detection hole is connected to the conductive groove 1113.

[0052] Example 2 7 to 9, this embodiment discloses a locking mechanism 1a, and the following description will omit the explanation of the parts that are the same as those in the locking mechanism of embodiment 1 and use the same reference numerals. Fig. 7 is an exploded schematic view of the locking mechanism of embodiment 2 of the present invention, Fig. 8 is a schematic view of the locking mechanism of embodiment 2 of the present invention in an unlocked state, and Fig. 9 is a schematic view of the locking mechanism of embodiment 2 of the present invention in a locked state.

[0053] 7 differs only in the configuration of the locking member 17 and the swinging member 12a. The swinging member 12a is configured as a separate body from the locking member 17.

[0054] The locking member 17 includes an integrally constructed locking member key cylinder 171, a storage portion 172, and a locking member insertion post 173. The locking member key cylinder 171 and the locking member insertion post 173 are located on either side of the storage portion 172, and the elastic member 15 is a spring that is fitted onto the locking member insertion post 173. The storage portion has an opening, for example, and one end of the swinging member 12a is inserted into the storage portion through the opening. The opposing side walls of the locking member key cylinder 171 and the locking member insertion post 173 form the walls of the storage portion 172, and the swinging member 12a transmits force by contacting each of the side walls.

[0055] The swinging member 12a is rotatably provided in the mounting cavity of the case 11. One end of the swinging member 12a that engages with the locking member 17 is long, and by inserting one end of the swinging member 12a into the accommodating portion 172 of the locking member 17, the swinging member 12a and the locking member 17 can move one another when one is driven.

[0056] Specifically, as shown in FIGS. 8 and 9 , one end of the swinging member 12a is inserted into the accommodation portion 172 of the locking member 17. When the motor 13 drives the eccentric wheel 14 to rotate, the eccentric wheel 14 presses the other end of the swinging member 12a against it, causing the swinging member 12a to rotate around its axis. One end of the swinging member 12a abuts against the side wall of the locking member 17 on the locking member insertion post 173 side within the accommodation portion 172, moving the locking member in the direction in which the spring is compressed, and the locking member key cylinder 171 retracts from the through-hole, unlocking the mobile battery. When the motor 13 stops driving and the eccentric wheel 14 no longer acts on the other end of the swinging member 12a, the locking member 17 is returned by the action of the spring, the swinging member 12a is driven to rotate around the axis 18, and the locking member key cylinder 171 protrudes from the through-hole. When the oscillating member 12a drives the locking member 17 to move, and when the locking member 17 drives the oscillating member 12a to move, the oscillating member 12a has a certain rotation space in the accommodating portion 172, that is, the oscillating member 12a and the accommodating portion 172 are not fastened together.

[0057] In this embodiment, the swinging member 12a and the locking member 17 are provided separately, and when the mobile battery is locked, it is more difficult for a person to pull it out than when the swinging member and locking member are an integrated structure. This is because when the swinging member and locking member are integrated, when the key cylinder protrudes from the through-hole and is in the locked state, the swinging member generates component forces in the direction to pull out the mobile battery and the unlock direction, which are perpendicular to each other, and the presence of these two component forces makes it easier for the mobile battery to be pulled out maliciously.

[0058] Fig. 10 is an exploded schematic diagram of a modified example of the locking mechanism of the second embodiment of the present invention, and is a schematic diagram of a structure in which one motor drives two oscillating members. The structures of the oscillating members and locking members in Fig. 10 are the same as those in Fig. 7, and the motor drive structure is the same as that in the first embodiment, so a description thereof will be omitted here.

[0059] Example 3 11 and 12, this embodiment discloses a mobile battery module 100 used for rental and return storage of mobile batteries, which includes a mounting bracket 2, an extrusion mechanism 3, and the locking mechanism 1 described in Example 1.

[0060] The mounting bracket 2 is provided with eight accommodating cavities 21, which are divided into four layers, each layer having two accommodating cavities 21, the two accommodating cavities 21 in the same layer being horizontally symmetrically arranged, each accommodating cavity 21 having an outlet end, each mobile battery can be accommodated in a different accommodating cavity 21, and an end cap 22 is further provided at the outlet end of each accommodating cavity 21, which can seal the accommodating cavity 21.

[0061] The extrusion mechanisms 3 are provided on the mounting bracket 2, specifically, there are eight extrusion mechanisms 3, each corresponding to a corresponding one of the accommodating cavities 21, and the extrusion mechanisms 3 push the mobile battery to protrude from the outlet end of the accommodating cavity 21.

[0062] The locking mechanism 1 in Example 1 is provided with four locking mechanisms 1, with two oscillating members 12 included, and the four locking mechanisms 1 are provided symmetrically, with two on each side of the mounting bracket 2, and each locking mechanism 1 corresponds to one of the two accommodating cavities 21, and the locking mechanisms 1 are used to lock or unlock the mobile battery.

[0063] Of course, if the locking mechanism 1 includes only one oscillating member 12, the number of locking mechanisms 1 must be equal to the number of accommodating cavities 21 so as to be able to lock all the mobile batteries placed in the accommodating cavities 21.

[0064] As can be understood, the number of the receiving cavities 21, the number of the pushing mechanisms 3, and the number of the locking mechanisms 1 can be changed according to design needs. This embodiment does not limit the number of the receiving cavities 21, the number of the pushing mechanisms 3, and the number of the locking mechanisms 1 in the charging module 100.

[0065] As can be understood, the ejection mechanism 3 may be any known mechanism for popping up a mobile battery, and the novelty of the present invention does not lie in the specific structure of the ejection mechanism 3. Therefore, no examples of the ejection mechanism 3 will be described in this specification.

[0066] The charging module 100 may have the locking mechanism described in Example 2 instead of the locking mechanism 1 described in Example 1, and other configurations are the same as those described above, so detailed explanations will be omitted here.

[0067] Referring to FIG. 13, in this embodiment, the charging module 100 further includes a verification module 4 and a second detection switch 5 for detecting the identification information of the mobile battery.

[0068] Each receiving cavity 21 is provided with a corresponding verification module 4 and a corresponding second detection switch 5. The verification module 4 may be provided inside or outside the receiving cavity 21. The verification module 4 may be a Hall sensor, an infrared sensing module, an NFC sensing module, etc., and may be used to determine whether the returned mobile battery is authentic or to auxiliary determine whether a mobile battery is received in the receiving cavity 21, and may be used in combination with the lock determination of the locking mechanism 1 to avoid erroneous return determination that occurs after only a portion of the mobile battery has been returned but the mobile battery is finally removed.

[0069] The second detection switch 5 is provided on one side wall away from the exit end of the receiving cavity 21 and abuts against the end of the mobile battery. After the mobile battery is inserted into the receiving cavity 21, the second detection switch 5 can be activated. The second detection switch 5 similarly determines whether the mobile battery is received in the receiving cavity 21. In combination with the lock determination of the locking mechanism 1, this avoids a false return determination that occurs after only completing a partial return operation of the mobile battery but finally withdrawing the mobile battery.

[0070] The operation process of the locking mechanism 1 and the charging module 100 according to this embodiment is generally as follows.

[0071] In the initial state, the elastic force of the elastic member 15 acts on the swinging member 12 , causing the key cylinder 121 to protrude from the through-hole 114 and extend into the accommodating cavity 21 , and the eccentric wheel 14 to separate from the abutment base 122 .

[0072] When the mobile battery is inserted into the receiving cavity 21, the side of the mobile battery begins to abut against the guide surface 1211 of the key cylinder 121. As the insertion of the mobile battery progresses, the abutment surface between the key cylinder 121 and the mobile battery gradually shifts from the guide surface 1211 to the end surface of the key cylinder 121. The mobile battery presses against the key cylinder 121 and moves it away. The oscillating member 12 swings in the opposite direction, compressing the elastic member 15. The oscillating member 12 initially presses the first detection switch. When the engagement groove of the mobile battery is aligned with the key cylinder 121, under the action of the elastic force of the elastic member 15, the oscillating member 12 swings in the forward direction, inserting the key cylinder 121 into the engagement groove of the mobile battery to lock it. The locking is completed, and the oscillating member 12 releases the first detection switch. The background system can determine that the mobile battery has been returned based on the initial power on / off of the first detection switch.

[0073] When the mobile battery needs to be popped up, the motor 13 starts to be energized, and the motor 13 drives the rotation of the eccentric wheel 14, so that the eccentric wheel 14 gradually comes into contact with the abutment base 122 of the oscillating member 12, and the abutment base 122 drives the oscillating member 12 to swing in the opposite direction, compressing the elastic member 15, and the oscillating member 12 presses the first detection switch a second time, causing the key cylinder 121 to retract, completing the unlocking process, and the ejection mechanism 3 is activated to pop up the unlocked mobile battery to the outside, and the motor 13 drives the rotation of the eccentric wheel 14, causing the eccentric wheel 14 to detach from the abutment base 122, and under the action of the elastic force of the elastic member 15, the oscillating member 12 swings in the forward direction, causing the key cylinder 121 to return to its protruding position, and the oscillating member 12 releases the first detection switch, and the background system can determine that the rental of the mobile battery is complete based on the second power on / off of the first detection switch.
