Description

Technical Field

[0001] The present invention relates to the technical field of mobile power supplies, and in particular to a tail-plug type mobile power supply. Background Art

[0002] In today's era of widespread use of mobile devices, mobile power banks are important accessories to ensure the battery life of mobile phones and other electronic devices, and their convenience and stability have attracted much attention. Tail-plug mobile power banks occupy a certain share in the market. Their working principle is to transmit power by directly inserting the charging plug into the charging port of the mobile phone.

[0003] When the existing tail-plug-type mobile power source uses the clamping arm to clamp the electronic device, it is necessary to open the clamping arm by hand. This process is relatively cumbersome and requires two-handed operation, which brings inconvenience to the user and increases the time cost of using the mobile power source. Summary of the invention

[0004] The main purpose of the present invention is to provide a tail plug-in type mobile power source, aiming to solve the technical problem that the opening operation of the clamping arm of the existing tail plug-in type mobile power source is complicated.

[0005] To achieve the above object, the present invention provides a tail-plug type mobile power supply, comprising:

[0006] case;

[0007] A charging device, comprising a battery and a charging interface, wherein the battery is disposed in the housing, and the charging interface is electrically connected to the battery and at least partially exposed to the housing;

[0008] A clamping device, comprising at least two clamping assemblies, wherein the at least two clamping assemblies are respectively located on opposite sides of the charging interface to form a clamping space for clamping the electronic device, and at least one of the at least two clamping assemblies is slidably disposed on the housing to move closer to or farther from the other under the action of an external force to reduce or expand the clamping space;

[0009] In which, the clamping assembly includes a clamping arm, a sliding member and a third elastic member, the sliding member is slidably arranged on the shell, the clamping arm is rotatably connected to the sliding member, and has an expanded state and a contained state, when the clamping arms of at least two of the clamping assemblies are in the expanded state, the clamping space is formed for clamping the electronic device, when the clamping arms of at least two of the clamping assemblies are in the contained state, the sliding member is at least partially exposed to the shell, so as to drive the clamping arm close to the charging port under the action of external force, or drive the clamping arm away from the charging port to release the clamping arm from the contained state, and the third elastic member is respectively connected to the clamping arm and the sliding member, and is used to drive the clamping arm to rotate relative to the sliding member to switch to the expanded state when the clamping arm releases the contained state.

[0010] In some embodiments, the shell is provided with a receiving groove for accommodating the clamping arm, the receiving groove is provided with a first clamping structure, and the clamping arm is provided with a second clamping structure. The first clamping structure and the second clamping structure are engaged with each other so that the clamping arm is clamped in the receiving groove, thereby realizing the receiving state of the clamping arm, and the second clamping structure can move with the clamping arm under the drive of the sliding member to disengage from the first clamping structure, so that the clamping arm releases the receiving state.

[0011] In some embodiments, one of the first clamping structure and the second clamping structure is a protruding clamping block, and the other is a recessed clamping slot corresponding to the clamping block, and the clamping block and the clamping slot are engaged with each other to enable the clamping arm to be clamped in the accommodating slot.

[0012] In some embodiments, the clamping assembly also includes a control member, which is slidably disposed on the shell and is transmission-connected to the sliding member. The control member is at least partially exposed from the shell so as to drive the sliding member to slide under the action of an external force to drive the clamping arm to move closer to or away from the charging port.

[0013] In some embodiments, the sliding member and the control member are spaced apart, a first rack is provided on a side of the sliding member facing the control member, and a second rack is provided on a side of the control member facing the sliding member;

[0014] The clamping assembly also includes a transmission gear, which is respectively meshed with the first rack and the second rack. The control member and the sliding member move in opposite directions under the action of external force.

[0015] In some embodiments, the first rack and the second rack are arranged in parallel and spaced apart from each other, and the first rack and the second rack are respectively extended along the length direction of the housing.

[0016] In some embodiments, the clamping assembly further includes a first elastic member, which is elastically supported between the housing and the sliding member so that the sliding member has a movement tendency to approach the charging port.

[0017] In some embodiments, the clamping assembly further includes a second elastic member, which is elastically supported between the shell and the control member so that the control member has a tendency to move away from the charging port.

[0018] In some embodiments, the rotation angle of the clamping arm relative to the sliding member is 0°-90°.

[0019] In some embodiments, the facing sides of the clamping arms of the at least two clamping assemblies are provided with an anti-slip structure.

[0020] The tail-plug-in mobile power provided by the present application can be connected to the clamping arm and the sliding member respectively by setting a third elastic member, which is used to drive the clamping arm to rotate relative to the sliding member to switch to the expanded state when the clamping arm is released from the storage state. When the user needs to use the mobile power supply to charge and clamp the electronic device, the sliding member is pushed by external force to drive the clamping arm away from the charging interface, so that the clamping arm is released from the storage state. At this time, the third elastic member will release elastic potential energy, drive the clamping arm to rotate relative to the sliding member, so that the clamping arm automatically switches to the expanded state. This operation process does not require the user to manually adjust the angle of the clamping arm, and the clamping arm can be expanded by one hand, thereby improving the convenience of the user when using the mobile power supply.

[0029] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0030] The scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] Please refer to Figures 1 to 4In one embodiment of the present application, a tail-plug-type mobile power source 1000 is provided, comprising a housing 100, a charging device 200 and a clamping device 300; the charging device 200 comprises a battery 210 and a charging interface 220, the battery 210 is arranged in the housing 100, the charging interface 220 is electrically connected to the battery 210, and at least partially exposed from the housing 100; the clamping device 300 comprises at least two clamping components 310, the at least two clamping components 310 are respectively located on opposite sides of the charging interface 220 to form a clamping space 320 for clamping the electronic device 2000, at least one of the at least two clamping components 310 is slidably provided on the housing 100, and is used to move closer to or farther from the other under the action of an external force, so as to reduce or expand the clamping space 320.

[0035] The battery 210 is used to store electrical energy. The charging interface 220 serves as a bridge between the battery 210 and external devices, and plays a role in transmitting electrical energy. When the charging interface 220 is connected to the electronic device 2000, the current output by the battery 210 is transmitted to the battery 210 or other electrical components of the electronic device 2000 through the circuit of the charging interface 220, thereby realizing the charging process.

[0036] It should be noted that the charging interface 220 can be configured according to usage requirements. For example, it can be equipped with at least one of a MicroUSB interface, a Type-C interface, and a Lightning interface, or a replaceable interface design can be adopted, so that the mobile power supply 1000 can be compatible with more electronic devices 2000 of different brands and models, further enhancing its versatility and applicability.

[0037] It is understandable that at least one clamping assembly 310 is slidably disposed on the housing 100, and such a sliding structure can be implemented by a guide rail, a slider or a similar mechanical structure. When an external force acts on the slidable clamping assembly 310, it moves relative to another clamping assembly 310 along the guide rail or other sliding mechanism on the housing 100. Through this relative movement, the size of the clamping space 320 can be adjusted according to the size of the electronic device 2000. For example, when facing a larger electronic device 2000, the user can push the sliding clamping assembly 310 to move outward to increase the clamping space 320; while for a smaller electronic device 2000, it slides inward to reduce the clamping space 320 to better fix the electronic device 2000, so that the mobile power supply 1000 can adapt to electronic devices 2000 of various sizes.

[0038] When in use, the user only needs to place the electronic device 2000 into the clamping space 320 and connect the charging interface 220, and then clamp and fix it through the clamping assembly 310, so as to simultaneously fix and charge the electronic device 2000, without having to find other fixing devices or tools. This simplifies the charging operation process and improves the convenience of use. Especially in some mobile scenarios (such as traveling, working outside, etc.), users can charge the electronic device 2000 more conveniently and keep the device fully charged anytime and anywhere.

[0039] The present application provides a clamping device 300 to firmly fix the electronic device 2000 at the charging interface 220 of the mobile power supply 1000, so as to ensure that the connection between the mobile power supply 1000 and the electronic device 2000 is stable and reliable during the charging process, and prevent the charging interface 220 from loosening or falling off due to external forces (such as shaking when the user holds the electronic device 2000, the gravity of the mobile power supply 1000 itself, etc.), greatly improve the connection stability during the charging process, reduce the occurrence of poor contact, charging interruption, etc., reduce the wear and tear of the charging interface 220 caused by shaking of the electronic device 2000 or inaccurate plugging and unplugging during the charging process, and ensure charging efficiency and device safety. Moreover, when the electronic device 2000 is clamped on the mobile power supply 1000, the overall space occupied is relatively small, and it is not easy to spread or lose parts. The user can put it as a whole into a backpack, pocket or other storage container for easy carrying and storage.

[0040] Please continue to refer to Figure 1 In some embodiments, the clamping assembly 310 includes a clamping arm 311, a sliding member 312 and a third elastic member 317. The sliding member 312 is slidably disposed on the housing 100. The clamping arm 311 is rotatably connected to the sliding member 312 and has an expanded state and a received state. When the clamping arms 311 of at least two clamping assemblies 310 are in the expanded state, a clamping space 320 is formed for clamping an electronic device. When the clamping arms 311 of at least two clamping assemblies 310 are in the received state, they are received in the housing 100. The sliding member 312 is at least partially exposed to the housing 100, so as to drive the clamping arm 311 to approach the charging port 220 under the action of an external force, or to drive the clamping arm 311 away from the charging port 220 to release the received state of the clamping arm 311. The third elastic member 317 is respectively connected to the clamping arm 311 and the sliding member 312, and is used to drive the clamping arm 311 to rotate relative to the sliding member 312 to switch to the expanded state when the clamping arm 311 is released from the received state.

[0041] Among them, the sliding member 312 is a key component connecting the clamping arm 311 and the housing 100, and its main function is to transmit external force to the clamping arm 311, so as to adjust the clamping space 320. The sliding member 312 is at least partially exposed to the housing 100, providing the user with an obvious and easy-to-operate external force application point. The user does not need to find complicated operating buttons or mechanisms, and can easily adjust the clamping space 320 by directly applying a push or pull external force to the exposed sliding member 312. This intuitive operation method enables the user to quickly and accurately complete the clamping operation of the device during use, thereby improving the convenience and efficiency of use. When the user applies external force to the sliding member 312 exposed to the housing 100, the sliding member 312 can slide along the preset slideway or guide rail structure on the housing 100.

[0042] It is understandable that the connection between the sliding member 312 and the clamping arm 311 can be achieved through a hinge, a screw lock or other mechanical connection structure, and the user's operation of the sliding member 312 can be accurately converted into the movement of the clamping arm 311, thereby achieving precise control of the size of the clamping space 320. When the sliding member 312 slides, it will drive the clamping arm 311 to move together. For example, when the sliding member 312 slides outward, it will drive the clamping arm 311 to slide outward, thereby increasing the clamping space 320; conversely, when the sliding member 312 slides inward, the clamping arm 311 slides inward, reducing the clamping space 320 to adapt to electronic devices 2000 of different sizes. In other words, the user can adjust the position of the sliding member 312 according to the actual size of the electronic device 2000, so that the clamping space 320 is perfectly matched with the electronic device 2000, thereby enhancing the versatility and practicality of the mobile power supply 1000.

[0043] Among them, the clamping arm 311 is rotatably connected to the sliding member 312, which can be a connecting structure such as a hinge or a pin, allowing the clamping arm 311 to rotate around a fixed axis relative to the sliding member 312, ensuring that the clamping arm 311 can flexibly change its angle relative to the sliding member 312 when subjected to external force or according to usage requirements, thereby achieving switching between the unfolded state and the retracted state.

[0044] When the clamping arm 311 is in the unfolded state, its main function is to clamp the electronic device 2000. At this time, the clamping arm 311 cooperates with another (or multiple) clamping arms 311 to form an effective clamping space 320 on opposite sides of the charging interface 220.

[0045] When the clamping arm 311 is in the receiving state, it is received in the housing 100, which makes the appearance of the entire mobile power supply 1000 more concise and compact, and is easy to carry and store. During the receiving process, the clamping arm 311 can rotate around the rotation connection point between it and the sliding member 312 until it is received in the receiving space specified by the housing 100.

[0046] Since the clamping arm 311 can be accommodated in the housing 100, when the clamping function is not needed, the entire mobile power supply 1000 presents a more compact appearance, which is easier to store and carry. Users can easily put it into a small storage space such as a pocket or a backpack without being inconvenienced by the protrusion of the clamping arm 311. In addition, the clamping arm 311 itself can be protected from external collision, wear and tear, etc., extending the service life of the clamping arm 311 and the entire mobile power supply 1000.

[0047] In this embodiment, the third elastic member 317 is connected between the clamping arm 311 and the sliding member 312, and generates elastic force by using its own elastic characteristics. When the entire clamping assembly 310 is in the receiving state, the third elastic member 317 is in a certain pre-compression state. In this state, the third elastic member 317 will apply an elastic force to the clamping arm 311, so that the clamping arm 311 has a movement tendency to rotate relative to the sliding member 312.

[0048] When the sliding member 312 is pushed by external force to drive the clamping arm 311 away from the charging port 220 so that the clamping arm 311 is released from the receptacle state, the elastic potential energy stored in the third elastic member 317 itself begins to be converted into kinetic energy, exerting an elastic force on the clamping arm 311, causing the clamping arm 311 to rotate relative to the sliding member 312 and open to both sides, thereby forming a clamping space 320 for clamping the electronic device 2000.

[0049] In this embodiment, the user does not need to manually and laboriously stretch out the clamping arm 311 to place the electronic device 2000. The clamping arm 311 can automatically pop open to form a clamping space 320, which can be completed with one hand. The operation is simple and quick, which greatly improves the convenience of using the mobile power supply 1000 to charge the electronic device 2000. Moreover, the automatic pop-up process is relatively smooth, and the electronic device 2000 will not be damaged by scratches or collisions caused by manually and roughly stretching out the clamping arm 311.

[0050] In this embodiment, the third elastic member 317 is a torsion spring, one end of the torsion spring abuts against the clamping arm 311, and the other end of the torsion spring abuts against the sliding member 312; in this way, by pressing the control members 313 on both sides of the mobile power supply 1000 at the same time, the two sliding members 312 are driven to slide in directions away from each other. At this time, the two clamping arms 311 are driven by the corresponding sliding members 312 to slide in directions away from each other, so that the clamping arms 311 can be released from the receptacle state. In this way, the clamping arms 311 can automatically rotate and open under the elastic action of the torsion spring, making it convenient for users to clamp the electronic device 2000.

[0051] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, the housing 100 is provided with a receiving groove 110 for accommodating the clamping arm 311, and a first clamping structure 111 is provided in the receiving groove 110, and the clamping arm 311 is provided with a second clamping structure 311a. The first clamping structure 111 and the second clamping structure 311a are engaged with each other so that the clamping arm 311 is clamped in the receiving groove 110, thereby realizing the receiving state of the clamping arm 311, and the second clamping structure 311a can move with the clamping arm 311 under the drive of the sliding member 312 to disengage from the first clamping structure 111, so that the clamping arm 311 is released from the receiving state.

[0052] The receiving groove 110 provided on the housing 100 provides a space for accommodating the clamping arm 311 , and the first clamping structure 111 in the receiving groove 110 and the second clamping structure 311 a on the clamping arm 311 are used to realize the clamping fit between the two components.

[0053] It is understandable that the first clamping structure 111 and the second clamping structure 311a usually have matching shapes and sizes. For example, the first clamping structure 111 can be a protruding clamping block, and the second clamping structure 311a can be a corresponding recessed clamping slot; or the first clamping structure 111 is a clamping slot, and the second clamping structure 311a is a clamping block. When the clamping arm 311 rotates to the receiving state and enters the receiving slot 110, the two clamping structures will be precisely aligned and mutually locked.

[0054] In the process of the clamping arm 311 entering the receiving slot 110, as the clamping arm 311 moves, the second clamping structure 311a gradually approaches the first clamping structure 111. When the positions of the two are completely corresponding, due to the matching of their shapes and sizes, they will achieve a clamping fit under the action of an external force (such as lightly pressing the clamping arm 311 to make it completely enter the receiving slot 110), thereby firmly fixing the clamping arm 311 in the receiving slot 110, preventing the clamping arm 311 from automatically falling out of the receiving slot 110 without being released by an external force, thereby achieving stable storage of the clamping arm 311 in the receiving state, and at this time, the entire mobile power supply 1000 has a more compact appearance, which is convenient for carrying and storage.

[0055] When switching from the stored state to the deployed state, a certain external force needs to be applied to the clamping arm 311 to release the engagement between the first clamping structure 111 and the second clamping structure 311a. The external force should be sufficient to overcome the engagement force between the clamping structures, so that the second clamping structure 311a can be released from the first clamping structure 111. Once the engagement is released, the clamping arm 311 can rotate again through the rotational connection with the sliding member 312, and expand outward to a suitable position, and cooperate with other clamping arms 311 to form a clamping space 320, so as to clamp and charge the electronic device 2000.

[0056] In this embodiment, the first clamping structure 111 and the second clamping structure 311a provide a stable fixing effect for the clamping arm 311 in the receiving slot 110. In the process of daily carrying or storing the mobile power supply 1000, even if the mobile power supply 1000 is subjected to a certain degree of external force such as shaking, collision or bumping, the clamping arm 311 will not easily fall out of the receiving slot 110.

[0057] Please refer to Figure 2 and Figure 5 In some embodiments, the clamping assembly 310 also includes a control member 313, which is slidably disposed on the shell 100, and the control member 313 is transmission-connected to the sliding member 312, and the control member 313 is at least partially exposed to the shell 100, so as to drive the sliding member 312 to slide under the action of an external force to drive the clamping arm 311 to move closer to or away from the charging port 220.

[0058] It is understandable that the control member 313 and the sliding member 312 are connected through a specific transmission connection structure, and this connection can be gear transmission, rack transmission, connecting rod transmission or other suitable mechanical transmission methods. For example, if a gear rack transmission is adopted, a gear structure is provided on the control member 313, and a rack structure is correspondingly provided on the sliding member 312. When the user applies an external force to the control member 313 exposed to the housing 100, the external force first acts on the control member 313. The control member 313, as an intermediate transmission medium, converts the received external force into its own sliding, and then drives the rack to move through the gear, thereby driving the sliding member 312 to slide along the housing 100, and then drives the clamping arm 311 connected thereto to approach or move away from the charging port 220, thereby reducing and expanding the clamping space 320. This indirect drive method realizes the overall linkage from the control member 313 to the clamping arm 311. During the whole process, the movement coordination between the various components ensures that the clamping device 300 can work stably and reliably.

[0059] In actual application, the smaller external force applied by the user to the control member 313 can be converted into a suitable sliding distance and speed of the sliding member 312 by reasonably selecting the transmission ratio and the size of the transmission structure. In this way, the user can more accurately adjust the position of the clamping arm 311 to adapt to electronic devices 2000 of different sizes. At the same time, the transmission connection can also play a certain role in force amplification or force reduction, and optimize the operating feel and control accuracy according to actual needs. For example, in some designs, in order to make it easier for the user to operate, the transmission structure may be used to convert the user's larger external force into a smaller force acting on the sliding member 312, so that the sliding member 312 can slide smoothly, avoiding excessive squeezing of the electronic device 2000 by the clamping arm 311 due to excessive force.

[0060] In this embodiment, the setting of the control member 313 provides the user with a more flexible and diversified operation mode to control the movement of the clamping arm 311. Compared with directly operating the sliding member 312, the control member 313 can be arranged in a more convenient position for operation or adopt a more ergonomic design according to the overall design of the mobile power supply 1000 and the user's usage habits, thereby avoiding the unreasonable spatial layout problem that may be caused by directly operating the sliding member 312.

[0061] Exemplarily, the sliding member 312 can be arranged near the charging interface 220 and the clamping arm 311 to achieve a more direct transmission effect, and the control member 313 can be arranged at a position that is more convenient for the user to operate and does not affect the layout of other components according to the shape and internal space of the housing 100, such as being designed on the side of the mobile power supply 1000 to facilitate the user to operate with fingers, or designed in a larger button shape to facilitate the user to operate at the same time when the electronic device 2000 is plugged into the charging interface 220 of the mobile power supply 1000. This flexibility allows the user to easily adjust the clamping arm 311 in different usage scenarios, improves the convenience and adaptability of the mobile power supply 1000, and also helps to reduce the overall size of the mobile power supply 1000, making it more portable.

[0062] Please refer to Figure 3 and Figure 5 As a preferred embodiment, the sliding member 312 and the control member 313 are spaced apart, a first rack 312a is provided on the side of the sliding member 312 facing the control member 313, and a second rack 313a is provided on the side of the control member 313 facing the sliding member 312;

[0063] The clamping assembly 310 further includes a transmission gear 314 , which is meshed with the first rack 312 a and the second rack 313 a , respectively. The control member 313 and the sliding member 312 move in opposite directions under the action of external force.

[0064] When the control member 313 slides in a certain direction under the action of external force, the second rack 313a on one side thereof will move together with the control member 313. Since the second rack 313a is meshed with the transmission gear 314, the transmission gear 314 will rotate accordingly. The rotation of the transmission gear 314 will drive the first rack 312a meshed with it to move. Since the first rack 312a is arranged on the sliding member 312, the sliding member 312 will move in the opposite direction to the control member 313 under the drive of the transmission gear 314. This method of using gears as intermediate transmission media and utilizing the meshing relationship between the rack and the gear to realize the relative movement of the two components (the control member 313 and the sliding member 312) can accurately transmit power and control the direction of movement.

[0065] Furthermore, due to the meshing relationship between the transmission gear 314 and the first rack 312a and the second rack 313a, when the control member 313 slides in one direction under the action of external force, such as sliding to the right, its second rack 313a moves to the right, causing the transmission gear 314 to rotate counterclockwise. The counterclockwise rotation of the transmission gear 314 will drive the first rack 312a to move to the left, thereby causing the sliding member 312 to slide to the left. At the same time, the clamping arm 311 will move to the left driven by the sliding member 312, thereby moving the clamping arm 311 away from the charging port 220, expanding the clamping space 320, so that a larger electronic device 2000 can be placed and clamped. On the contrary, when the control member 313 slides to the left, the second rack 313a moves to the left, and the transmission gear 314 rotates clockwise, thereby driving the first rack 312a to move to the right, causing the sliding member 312 to slide to the right, and the clamping arm 311 will move to the right, close to the charging port 220, and reduce the clamping space 320, which can be used to clamp smaller electronic devices 2000. Therefore, through the design of this transmission structure, the control member 313 and the sliding member 312 can move in opposite directions respectively under the action of external force, thereby realizing flexible adjustment of the clamping arm 311 to change the size of the clamping space 320 to adapt to electronic devices 2000 of different sizes.

[0066] In addition, during the entire transmission process, since the gear rack transmission has high precision and stability, it can accurately convert the external force of the control member 313 into the corresponding movement of the clamping arm 311. This precise transmission method can ensure that the clamping arm 311 will not shake or get stuck during the movement, thereby ensuring the stability of the clamping of the electronic device 2000. When the electronic device 2000 is placed in the clamping space 320, the stable clamping can prevent the interruption of charging and falling off due to accidental shaking during the charging process, thereby improving the safety and reliability of charging.

[0067] Please continue to refer to Figure 5In some embodiments, the first rack 312 a and the second rack 313 a are arranged in parallel and spaced apart from each other, and the first rack 312 a and the second rack 313 a are respectively extended along the length direction of the housing 100 .

[0068] Since the first rack 312a and the second rack 313a are parallel and spaced apart from each other, the transmitted force can be evenly distributed between the two during mechanical transmission, thereby avoiding local wear or damage caused by force concentration and extending the service life of the rack and related transmission components. In addition, the parallel and relative arrangement enables the load on the rack during transmission to be distributed more evenly on its tooth surface, reducing the occurrence of unbalanced loading.

[0069] In addition, the first rack 312a and the second rack 313a extending along the length direction of the housing 100 can achieve a larger transmission stroke in a limited space. This layout makes full use of the space inside the housing 100, making the structure of the entire mobile power supply 1000 more compact, helping to reduce the overall volume of the mobile power supply 1000, and improving the space utilization of the mobile power supply 1000, making it more suitable for use in an environment with limited space.

[0070] In some embodiments, the clamping assembly 310 further includes a first elastic member 315 , which is elastically supported between the housing 100 and the sliding member 312 , so that the sliding member 312 has a movement tendency to approach the charging port 220 .

[0071] The first elastic member 315 is disposed between the housing 100 and the sliding member 312, and exerts force on the sliding member 312 through elastic deformation. When the clamping assembly 310 is in the initial state or is not subjected to external force, the first elastic member 315 is in a natural state or a certain pre-compression state, and generates an elastic force on the sliding member 312 toward the charging interface 220. This elastic force makes the sliding member 312 have a movement tendency close to the charging interface 220, so that the clamping arm 311 is in a position relatively close to the charging interface 220, forming a relatively small clamping space 320 initial state, so as to facilitate clamping of the electronic device 2000 and improve the clamping stability of the electronic device 2000.

[0072] When the control member 313 is acted upon by an external force and drives the sliding member 312 to move in the opposite direction (away from the charging interface 220) through the transmission gear 314, the first elastic member 315 will be further compressed, and its stored elastic potential energy will increase. When the external force is removed, the first elastic member 315 releases the stored elastic potential energy, and pushes the sliding member 312 back to a position close to the charging interface 220, restoring to the initial state, and clamping the electronic device 2000 placed in the clamping space 320.

[0073] In this embodiment, since the first elastic member 315 can realize the automatic reset function of the sliding member 312 and the clamping arm 311, the wear of the components that may be caused by frequent manual adjustment of the size of the clamping space 320 is reduced. For example, frequently pushing and pulling the sliding member 312 to change the size of the clamping space 320 may increase the friction between the sliding member 312 and the housing 100, thereby accelerating the wear of the components. The presence of the first elastic member 315 makes it unnecessary to make manual adjustments in many cases, thereby reducing the wear rate of the components and extending the service life of the entire clamping assembly 310 and the mobile power supply 1000.

[0074] In some embodiments, the clamping assembly 310 further includes a second elastic member 316 , which is elastically supported between the housing 100 and the control member 313 , so that the control member 313 has a tendency to move away from the charging port 220 .

[0075] The second elastic member 316 is disposed between the housing 100 and the control member 313, and generates and applies force by virtue of its own elastic properties. When not disturbed by external forces, the second elastic member 316 is in a natural state or in a certain pre-stretched or pre-compressed state, and at this time, it applies an elastic force to the control member 313 to make it move away from the charging interface 220.

[0076] When the user needs to charge the electronic device 2000, an external force needs to be applied to the control member 313 to drive the sliding member 312 and then adjust the clamping arm 311. The external force needs to overcome the elastic force of the second elastic member 316 to move the control member 313 toward the direction close to the charging interface 220. In this process, the transmission gear 314 and other components work together to realize the opening of the clamping arm 311 to expand the clamping space 320. At this time, the electronic device 2000 is plugged into the charging interface 220, and then the force on the control member 313 is withdrawn. At this time, the control member 313 is reset under the action of the second elastic member 316, and the sliding member 312 is reset under the action of the first elastic member 315, and at the same time, the clamping arm 311 is driven to clamp the electronic device 2000.

[0077] When the user finishes charging the electronic device 2000 and wants to separate the electronic device 2000 from the charging interface 220, it is necessary to apply external force to the control member 313 to make the clamping arm 311 open again so that the clamping arm 311 no longer clamps the electronic device 2000. At this time, the electronic device 2000 can be separated from the charging interface 220, and then the external force is withdrawn. At this time, the elastic potential energy of the first elastic member 315 and the second elastic member 316 is released, and the corresponding push sliding member 312 and the control member 313 are reset, thereby realizing the automatic reset function of the entire clamping assembly 310, preparing for the next charging operation, and ensuring the ease of use and continuity of the clamping device 300.

[0078] In this embodiment, the second elastic member 316 gives the control member 313 a tendency to move away from the charging interface 220. When the user applies external force to the control member 313, the user can clearly feel the need to overcome this elastic force, thereby providing the user with clear operational feedback. The user can use this feedback to more accurately grasp the size and direction of the external force applied by the user, thereby more accurately controlling the position adjustment of the clamping arm 311.

[0079] In addition, the second elastic member 316 makes the control member 313 relatively far away from the charging interface 220, and cooperates with the first elastic member 315 to make the sliding member 312 relatively close to the charging interface 220, thereby creating a relatively stable initial state. In this initial state, the relative positions of the various components of the entire clamping assembly 310 are relatively fixed, reducing the possibility of position changes of the clamping arm 311 due to accidental shaking or external force interference, thereby improving the clamping stability.

[0080] In some embodiments, the rotation angle of the clamping arm 311 relative to the sliding member 312 is 0°-90°.

[0081] In this embodiment, the rotation angle of the clamping arm 311 relative to the sliding member 312 is 0°-90°. For example, when the clamping arm 311 is at 0°, it is in a receiving state, and the clamping arm 311 can be completely received in the receiving groove 110 of the housing 100, and a stable receiving is achieved through the clamping structure to maintain the compactness and portability of the mobile power supply 1000. When it is rotated to 90°, the maximum expansion angle for effective clamping can be provided. At this angle, the clamping arm 311 and another (or more) clamping arms 311 can form a suitable clamping space 320 on the opposite sides of the charging interface 220 to adapt to electronic devices 2000 of different sizes, and at the same time, it can ensure that there is enough contact area with the surface of the electronic device 2000 during the clamping process to ensure the stability of the clamping.

[0082] Since electronic devices 2000 of different sizes require clamping spaces 320 of different sizes, the change in the rotation angle of the clamping arm 311 between 0° and 90° enables the mobile power supply 1000 to better adapt to various electronic devices 2000. For example, for small electronic devices 2000, the clamping arm 311 can be rotated to a smaller angle (such as 30°-40°) to form a relatively small but sufficient clamping space 320 for fixing; for medium-sized electronic devices 2000, it can be rotated to a moderate angle (such as 50°-60°); for large electronic devices 2000, such as tablet computers, the clamping arm 311 can be rotated to an angle close to 90° to ensure that there is enough clamping space 320 to accommodate and stably clamp.

[0083] In order to make the clamping arms 311 clamp the electronic device 2000 more stably and securely, in this embodiment, the clamping arms 311 of at least two clamping assemblies 310 are provided with anti-slip structures 311 b on the facing sides thereof.

[0084] When the clamping arms 311 of at least two clamping assemblies 310 are arranged facing each other to form a clamping space 320 for clamping the electronic device 2000, an anti-slip structure 311b is arranged on the facing side thereof, mainly for the purpose of increasing the friction between the clamping arms 311 and the electronic device 2000. In this way, the electronic device 2000 can be better fixed, and the electronic device 2000 can be prevented from being interrupted in charging or the charging interface 220 being loosened due to accidental shaking or movement during the charging process, thereby improving the stability of charging and ensuring that the charging current can be continuously and stably transmitted to the electronic device 2000.

[0085] Among them, the anti-skid structure 311b can be realized by surface roughening, adding anti-skid materials (such as rubber, silicone and other materials with high friction coefficient) or designing specific textures (such as horizontal stripes, vertical stripes, grid stripes, etc.). These anti-skid measures make the contact between the clamping arm 311 and the electronic device 2000 no longer a smooth surface contact, but a multi-point contact or a contact with a certain obstruction effect is formed through the anti-skid structure 311b, thereby greatly increasing the friction. For example, when the anti-skid structure 311b made of rubber material contacts the surface of the electronic device 2000, its own softness and high friction coefficient characteristics can fit closely to the surface of the electronic device 2000, and even when the electronic device 2000 is slightly shaken by external force, the electronic device 2000 can be firmly fixed by friction.

[0086] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
