Description

Technical Field

[0001] The invention relates to a charging compartment of a mobile charging device. Background Art

[0002] As the functions of electronic devices such as smartphones continue to increase, their power consumption is also gradually increasing. On the one hand, electronic device manufacturers continue to increase the battery capacity of electronic devices, and on the other hand, they provide mobile charging devices such as mobile power banks for devices whose mobile phone battery capacity is not ideal. With the development of the sharing economy, there are new product solutions for shared mobile power banks. In the solution of shared mobile power bank products, multiple mobile power banks are inserted into the charging cabinet for charging. When the user follows the prompts on the charging cabinet to rent, the user obtains the right to take out a mobile power bank from the charging cabinet, or a charging power bank is ejected by the mechanical structure, and the user can take the mobile power bank for use. After the user is finished using it, the mobile power bank can be returned to the charging cabinet.

[0003] The charging cabinet is provided with at least one charging compartment for accommodating a mobile charging device. As a shared charging cabinet, it is necessary to allow the user to take out the mobile charging device in the charging compartment after the user has paid. For this purpose, the charging compartment needs to provide the function of locking and unlocking the mobile charging device placed therein. The charging compartment in the prior art is too complex in structure and high in cost when implementing the locking and unlocking functions. Summary of the invention

[0004] The object of the present invention is to provide a charging compartment for a mobile charging device, which can realize authority control for users to take out the mobile charging device.

[0005] To achieve the above object, the present invention provides a mobile charging device charging compartment, comprising:

[0006] A compartment body, having a compartment for accommodating a mobile charging device, and one end of the compartment has an entrance for inserting the mobile charging device;

[0007] Push rod and locking member;

[0008] Wherein, in the locked state, the locking end of the locking member extends from the compartment body into the compartment and is inserted into the locking groove of the mobile charging device, so that the mobile charging device overcomes the outward pushing force applied by the mobile charging device pop-up mechanism; in the unlocked state, the push rod moves toward the locking member, pushing the locking member to move outside the compartment, and then the locking end of the locking member is disengaged from the locking groove of the mobile charging device, so that the mobile charging device is ejected to the outside of the compartment under the action of the force applied by the mobile charging device pop-up mechanism;

[0009] The push rod push limiting device is used to limit the movement of the push rod in a locked state and release the restriction on the movement of the push rod in a non-locked state.

[0010] In a preferred embodiment, the push rod limiting device includes a stop rod telescopic controller and a stop rod. The extended length of the stop rod is controlled by the stop rod controller. The telescopic trajectory of the stop rod intersects with the moving trajectory of the push rod. A clamping structure cooperating with the stop rod is provided on the push rod. When the extended length of the stop rod reaches a position where it blocks the movement of the clamping structure, the push rod limiting device is in a clamped state. When the retracted length of the stop rod reaches a position where it no longer blocks the movement of the clamping structure, the push rod limiting device is in an unclamped state.

[0011] In a preferred embodiment, the stop rod telescopic controller includes an electromagnetic lock, and the extended length of the stop rod is controlled by the electromagnetic force applied by the electromagnetic lock.

[0012] In a preferred embodiment, the clamping structure provided on the push rod is a stop piece or a stop ring.

[0013] In a preferred embodiment, it further includes:

[0014] A mobile charging device ejection mechanism for applying an outward pushing force to the mobile charging device after the mobile charging device is inserted into the chamber;

[0015] In a preferred embodiment, one end of the push rod facing the locking member has an inclined pushing surface, and the locking member has a supporting surface cooperating with the inclined pushing surface;

[0016] During the process of the push rod moving towards the locking member, the inclined pushing surface pushes the supporting surface to move away from the housing, and thus the locking member moves towards the outside of the chamber.

[0017] In a preferred embodiment, under the action of a first return spring, the locking member is in a locked state; during the process of the push rod pushing the locking member towards the outside of the chamber, the locking member overcomes the elastic force of the first return spring, so that the locking member gets out of the locked state.

[0018] In a preferred embodiment, under the elastic force of a second return spring, the push rod returns to its initial position; during the process of an external force pushing the push rod towards the locking member, the push rod overcomes the elastic force of the second return spring.

[0019] In a preferred embodiment, the mobile charging device ejection mechanism includes a third return spring and a sliding hook that can slide towards the outside of the chamber under the elastic force of the third return spring. A part of the sliding hook extends into the chamber, and the housing has a sliding hole for the part of the sliding hook extending into the chamber to slide.

[0020] In a preferred embodiment, a push button is provided at one end of the push rod away from the locking member. A raised edge is provided on the side surface of the push button. A limit hole mechanism is provided at a position of the cartridge body close to the push button. The push button passes through the limit hole mechanism. When the push rod is in the initial state position under the elastic force of the second return spring, the raised edge of the push button abuts against the inner side of the limit hole mechanism to limit the outward movement of the push rod.

[0021] Through the above solution, the structure is simple, the cost is low, and the permission control for the user to take out the mobile charging device can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0030] Figure 1A FIG. shows a top view of a charging cartridge of a mobile charging device provided by an embodiment of the present invention, Figure 1B is a side view of the charging cartridge of the mobile charging device, Figure 1C is a three-dimensional schematic diagram of the charging cartridge of the mobile charging device, Figure 1D and Figure 1EThis is an exploded view of the charging compartment of the mobile charging device. Figure 2 for Figure 1A AA direction cross-sectional view, Figure 3 for Figure 1A BB direction cross-sectional view.

[0031] Please also see Figures 1A - 1E The mobile charging device charging compartment in this embodiment includes a compartment body 1, a mobile charging device ejection mechanism 2, a push rod 3 and a locking member 4.

[0032] The compartment 1 has a compartment 10 for accommodating a mobile charging device (not shown). One end of the compartment 10 has an inlet 10a for inserting the mobile charging device. In practice, the user can insert the mobile charging device into the compartment 10 through the inlet 10a, or remove the mobile charging device from the compartment 10 through the inlet 10a.

[0033] When the mobile charging device is pushed into the chamber 10 from the entrance 10a, after certain conditions are met (for example, when the pushing depth exceeds a predetermined depth), the mobile charging device ejection mechanism 2 applies an outward pushing force to the mobile charging device. The outward pushing force here can be a force pushing in the direction of the entrance 10a. Of course, in an alternative embodiment, the mobile charging device ejection mechanism 2 may apply an outward pushing force to the mobile charging device without any conditions, as long as the mobile charging device is just pushed into the chamber 10, the mobile charging device ejection mechanism 2 applies an outward pushing force to it.

[0034] The function of the mobile charging device ejection mechanism 2 is that, in the absence of other external forces, the mobile charging device can be ejected from the compartment 10 by the mobile charging device ejection mechanism 2, so that the user can take out the mobile charging device conveniently. If there is no such mechanism, the user needs to laboriously pull out the mobile charging device that has been pushed deep into the compartment 10. In a more serious case, if the depth of the mobile charging device pushed in is close to or greater than the length of the mobile charging device itself (in this case, the mobile charging device is almost completely placed in the compartment 10), the user will not be able to find a force-applying position to pull it out.

[0035] The mobile charging device ejection mechanism 2 can be implemented in a variety of specific ways, for example, it can be at least one spring with one end fixed to the inner wall of the end of the chamber 10 away from the entrance 10a, and the spring can use elastic thrust as a force to push the mobile charging device outward. Figures 1A - 1E , Figure 2 and Figure 3 The mobile charging device ejection mechanism 2 includes a third return spring 22 (only in Figure 1A and Figure 1BAs shown in [reference], there is a sliding hook 21 that can slide outward from the chamber 10 under the elastic force of the third return spring 22. The so-called sliding outward from the chamber 10 can be sliding in the direction of the entrance 10a. A part 21a of the sliding hook 21 extends into the chamber 10 (see Figure 3 ). There is a sliding hole 11 on the housing 1 for the part of the sliding hook 21 extending into the chamber 10 to slide. Also see Figure 1D and Figure 3 . It can be seen that the sliding hook 21 is generally in an L-shaped structure, including a part 21a extending into the chamber 10 and a part 21b located outside the chamber 10. The sliding track of the part 21a of the sliding hook 21 extending into the chamber 10 is restricted by the length and extension direction of the sliding hole 11. The sliding hook 21 can abut against one end of the mobile charging device away from the entrance 10a by means of the part 21a extending into the chamber 10. During the process of the part 21a sliding along the sliding hole 11 in the direction of the entrance 10a, the mobile charging device is pushed in the direction of the entrance 10a. The power for the sliding hook 21 to slide outward is provided by the third return spring 22. For example, the pulling force of the third return spring 22 returning from the stretched state to the original state can urge the sliding hook 21 to slide in the direction of the entrance 10a.

[0036] The push rod 3 and the locking member 4 cooperate to lock and unlock the position of the mobile charging device inserted into the chamber 10. In the locked state, the locking member 4 locks the position of the mobile charging device, making it overcome the outward pushing force exerted by the mobile charging device ejection mechanism 2. Unlocking can be completed by means of the push rod 3, so that the locking member 4 loses the locking of the position of the mobile charging device, and the mobile charging device is pushed in the direction of the entrance 10a under the action of the thrust of the mobile charging device ejection mechanism 2.

[0037] Please also see Figure 1D , Figure 1E and Figure 2 . One end of the locking member 4 forms a locking end 42. In the locked state, the locking end 42 of the locking member 4 extends into the chamber 10 from outside the housing 1 and is inserted into a locking groove (not shown in the figure) provided on the housing of the mobile charging device inserted into the chamber 10. In the unlocked state, the push rod 3 moves towards the locking member 4, pushing the locking member 4 to move outside the chamber 10. Then, the locking end 42 disengages from the locking groove of the mobile charging device, so that the mobile charging device pops out towards the outside of the entrance 10a under the action of the thrust exerted by the mobile charging device ejection mechanism 2.

[0038] One end of the push rod 3 facing the locking member 4 has an inclined pushing surface 31, and the locking member 4 has a supporting surface that cooperates with the inclined pushing surface 31. During the process of the push rod 3 moving towards the locking member 4, the inclined pushing surface 31 pushes the supporting surface to move away from the housing, and then the locking member 4 moves outside the chamber 10, that is, moves in the opposite direction to the direction in which the locking end 42 is inserted into the housing 1.

[0039] Under the action of the first return spring 5, the locking member 4 is in a locked state. The first return spring 5 provides a thrust for the locking member 4 to extend into the chamber 10, so that the locking end 42 can extend into a locking groove (not shown in the figure) provided on the housing of the mobile charging device. During the process of the push rod 3 pushing the locking member 4 to move outside the chamber 10, the locking member 4 overcomes the elastic force of the first return spring 5, so that the locking member 4 gets out of the locked state and enters the unlocked state.

[0040] As Figure 1D , Figure 1E and Figure 2 shown, the locking member 4 has a middle hole 41 extending through in a direction parallel to the extending direction of the push rod 3, and the upper inner edge 41a of the middle hole 41 of the locking member 4 serves as a supporting surface 41a that cooperates with the inclined pushing surface 31 of the above-mentioned push rod 3. When the push rod 3 is pushed to move towards the locking member 4, the inclined pushing surface 31 abuts against the upper inner edge 41a of the middle hole 41 of the locking member 4. The height of the inclined pushing surface 31 in the direction away from the locking member 4 is higher, and the height of the part in the direction close to the locking member 4 is lower. Therefore, when the inclined pushing surface 31 gradually moves towards the locking member 4, through the cooperation with the inner edge 41a, the locking member 4 is pushed in a direction perpendicular to the moving direction of the push rod 3, so that the locking member 4 gradually moves outside the chamber 10, overcoming the thrust of the first return spring 5 during the moving process. Finally, the locking end 41 of the locking member 4 moves out of the locking groove of the mobile charging device and enters the unlocked state, and the mobile charging device is ejected from the entrance 10a under the action of the mobile charging device ejection mechanism 2.

[0041] If the push rod 3 can rebound to the initial state position after being pushed by the user to make the locking member 4 in the unlocked state, it will be more reasonable for the user experience. Because if the push rod 3 has been in the unlocked state position, when the mobile charging device is inserted into the chamber 10 again and attempts to be pushed into the locked state, the position of the locking member 4 will be restricted by the push rod 3 and cannot return to the locked state position. For this reason, in the preferred embodiment, a second return spring 6 (only shown in Figure 1A and Figure 1B ) is provided. Under the elastic force of the second return spring 6, the push rod 3 can return to the initial state position. When the push rod 3 is in the initial state, the locking member 4 is no longer restricted by the push rod 3, and the locking member 4 will be pushed back to the locked state position under the action of the first return spring 5. When the user pushes the mobile charging device into the chamber 10 again, the locking end 41 of the locking member 4 will slide into the locking groove of the mobile charging device, and the mobile charging device is locked again.

[0042] The push rod 3 may be provided with a pin 33 for passing through the second return spring 6. On the one hand, the pin 33 prevents the second return spring 6 from twisting and deforming when being squeezed. On the other hand, one end of the pin 33 can abut against the second return spring 6. The other end of the second return spring 6 can abut against other structures on the housing 1, so that when the user pushes the push rod 3, the second return spring 6 is compressed by force, and then generates an elastic force that rebounds against the push rod 3.

[0043] One end of the push rod 3 away from the locking member 4 may also be provided with a push button 34, and a raised edge 34a is provided on the side surface of the push button 34. A limit hole mechanism 12 is provided at a position on the housing 1 close to the push button 34. The push button 34 passes through the limit hole mechanism 12. When the push rod 3 is in the initial state position under the elastic force of the second return spring 6, the raised edge 34a of the push button 34 abuts against the inner side of the limit hole mechanism 12, restricting the outward movement of the push rod 3 and preventing the push rod 3 from completely falling off.

[0044] See Figures 1A - 1E , the charging bin of the mobile charging device further includes a fixed upper cover 7. The upper cover 7 can perform various functions to make the structure of the whole device more delicate.

[0045] In this embodiment, the shape of the upper cover 7 is exquisitely designed to be similar to the letter "T". The upper cover 7 not only serves as a protective cover for other structures, but also provides necessary support for the functions of other structures, which will be elaborated in detail below.

[0046] A first hook 71 may be provided on the upper cover 7, and a second hook 211 is provided on the sliding push hook 21. Both ends of the third return spring 22 used to provide power for the sliding of the sliding push hook 21 can be sleeved on the first hook 71 and the second hook 211 respectively. In this way, when the user pushes the mobile charging device into the chamber 10, the mobile charging device will push the sliding push hook 21 to move away from the entrance 10a of the chamber 10. This movement will cause the third return spring 22 to stretch, and this stretching movement causes the third return spring 22 to always apply a rebounding elastic force to the sliding push hook 21. This rebounding elastic force will enable the sliding push hook 21 to push the mobile charging device outwards in the unlocked state.

[0047] In order to make the thrust exerted by the sliding push hook 21 on the mobile charging device more uniform and stable, in a preferred manner, the sliding push hook 21 can be set as at least two sliding push hooks 21 arranged in a direction perpendicular to the sliding direction. The at least two sliding push hooks 21 are connected into an integral sliding push hook assembly through a push hook connecting piece 23 parallel to the surface of the bin body 1. The push hook connecting piece 23 has at least one sliding limit hole 24, and the extending direction of the sliding limit hole 24 is parallel to the sliding direction of the sliding push hook 21, and thus is parallel to the extending direction of the sliding hole 11 on the bin body 1 for the sliding of the sliding push hook 21. A fixing column 25 is arranged outside the bin body 1 and is matched with the sliding limit hole 24. The fixing column 25 passes through the sliding limit hole 24. Through the cooperation of the fixing column and the sliding limit hole 24, the sliding direction and the sliding distance of the entire sliding push hook assembly are further limited. The fixing column can also be used as a fixing device for the upper cover 7, fixing the upper cover 7 on the bin body 1 and being generally outside the sliding hook assembly. The sliding hook assembly can slide between the upper cover 7 and the outer wall of the bin body 1 along a direction parallel to the extending direction of the bin chamber. In a preferred manner, in order to enhance the tightness between the upper cover 7 and the sliding hook assembly and ensure the stability of the sliding hook assembly during sliding, the upper cover 7 and the sliding hook assembly can be arranged in a cross-laminated manner, such as Figure 1D in the exploded view shown, the upper cover 7 and the sliding hook assembly are in a combined structure, Figure 1E in the exploded view shown, the upper cover 7 and the sliding hook assembly are completely separated to clearly show their respective structures. Comparing Figure 1D and Figure 1E it can be seen that although the upper cover 7 is generally above the sliding hook assembly, in fact, the push hook connecting piece 23 of the sliding hook assembly forms a ridge-shaped structure. In the assembled state, the push hook connecting piece 23 straddles outside the upper cover 7, while the sliding push hook 21 of the sliding hook assembly is located below the upper cover 7. In this way, the upper surface and the side surface of the upper cover 7 actually also serve as the limiting surfaces during the sliding of the push hook connecting piece 23, making the sliding of the entire sliding hook assembly more stable.

[0048] In addition, referring to Figure 1D 、 Figure 1E and Figure 2 simultaneously, a spring accommodating groove 72 can also be provided on one side of the upper cover 7 facing the first return spring 5. One end of the first return spring 5 extends into the spring accommodating groove 72, and the other end abuts against the locking member 4. One end of the locking member 4 facing the first return spring 5 can be provided with a pin for the first return spring 5 to be sleeved.

[0049] As can be seen from the above, the upper cover 7 can play multiple roles, including limiting the first return spring 5, fixing one end of the third return spring 22, limiting and protecting the sliding push hook assembly. Through the upper cover 7, the entire structure is made more delicate.

[0050] In summary, the mobile charging device charging compartment provided by the embodiment of the present invention can realize the locking and unlocking of the mobile charging device placed in the riding pet, and can also eject the mobile charging device in the unlocked state, so that the user can take it out conveniently. The whole device has a simple structure and low cost.

[0051] On the other hand, once the user successfully presses the push rod, the mobile charging device will be unlocked and popped out. However, in real-life shared mode operations, only users who have completed payment have the right to take out the mobile charging device. For this reason, the user's action of pressing the push rod should be restricted. For example, only users who have completed payment can normally press the push rod of the mobile charging device charging compartment, and other users will not be able to press the push rod normally.

[0052] In order to achieve the above objectives, Figures 1A - 1D , an improved structure is shown, in which a push rod push limiting device is added. The push rod push limiting device is used to limit the movement of the push rod 3 in a clamped state, and to release the restriction on the movement of the push rod 3 in a non-clamped state.

[0053] The locked state may correspond to a state in which the mobile charging device is locked in the charging compartment of the mobile charging device and the user is not authorized to use the mobile charging device. In the locked state, the user cannot press the push rod, so the mobile charging device is always in a locked state.

[0054] The non-fixed state can be a state where the mobile charging device is locked in the charging compartment of the mobile charging device and the user has the right to use the mobile charging device. In the non-fixed state, the user can press the push rod to cause the mobile charging device to switch to the unlocked state.

[0055] The specific components of the push display device may include a barrier rod 81 and a barrier rod telescopic controller 82. In practice, in order to facilitate the fixing of the barrier rod telescopic controller 82, a fixing frame 83 may be added to fix the barrier rod telescopic controller 82. The fixing frame 83 is fixed to the outer wall of the warehouse body 1.

[0056] The extension length of the blocking rod 81 is controlled by the blocking rod controller 82, and the extension trajectory of the blocking rod 81 intersects with the moving trajectory of the push rod 3. The push rod 3 is provided with a clamping structure 35 that cooperates with the blocking rod 81. When the blocking rod 81 is extended to a length that prevents the clamping structure 35 from moving, the push rod push limiting device is in the above-mentioned clamping state, and when the blocking rod 81 is retracted to a length that no longer prevents the clamping structure 35 from moving, the push rod push limiting device is in a non-clamping state.

[0057] exist Figures 1A - 1DIn the implementation shown, the telescopic trajectory of the shift lever 81 is almost perpendicular to the movement trajectory of the push rod 3. When the shift lever 81 extends a long distance under the control of the shift lever controller 82, the shift lever 81 will block the movement of the clamping structure 35, thereby restricting the entire push rod 3 from being pressed. When the shift lever 81 extends a short distance (or retracts in length) under the control of the shift lever controller 82, the shift lever 81 no longer blocks the movement of the clamping structure 35, and thus the entire push rod 5 can be pressed. The clamping structure 35 can be a stop piece as shown in Figures 1A - 1D or a stop ring. A hole for the shift lever 81 to pass through can be provided at the center of the stop ring.

[0058] The shift lever telescopic controller 82 can be implemented by a controller with a mechanical control mechanism or a controller with an electrical mechanism. In a preferred embodiment, an electromagnetic lock can be used as the shift lever telescopic controller 82. The electromagnetic lock will control the extension length of the shift lever 81 through the control of electromagnetic force.

[0059] Thus, the above solution can achieve the permission control for the user to take out the mobile charging device.

[0060] Please note that the above is only the preferred embodiment of the present invention and the applied technical principles. Those skilled in the art will understand that the present invention is not limited to the specific embodiments here, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
