Description

Technical Field

[0001] This utility model relates to the technical field of mobile power supplies, and in particular to a wireless mobile power supply. Background Technology

[0002] Wireless charging primarily utilizes electromagnetic induction technology, exchanging magnetic energy for electrical energy through changes in magnetic flux. Wireless power banks, based on this technology, have built-in battery devices that obtain power through wireless induction for charging.

[0003] Most wireless power banks on the market charge mobile devices by placing the device directly on the power bank. These power banks generally do not have a clamping structure to hold the device in place, or they simply use magnetic attachments to hold the device. This makes it easy for the device to detach from or become misaligned when the user moves around with the power bank, affecting normal charging. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a wireless mobile power supply to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a wireless power bank, which includes a power bank housing, a wireless charging module, a clamping base, and a cover plate.

[0007] The power bank housing has an opening forming a downwardly recessed receiving cavity; the wireless charging module is fixed in the receiving cavity; there are two clamping seats, which are located on opposite sides of the wireless charging module in the receiving cavity. Each clamping seat includes a claw, a slider, a groove, a spring, and a spring mounting platform. The two spring mounting platforms are fixed at the front and rear ends of the receiving cavity. The groove and the spring both extend along the length of the receiving cavity. One end of the spring is connected to the spring mounting platform, and the other end of the spring is connected to the slider. The claw is connected to the slider, and the slider can drive the claw to slide along the groove. A cover plate is placed on the receiving cavity. The top surface of the cover plate is used to place the mobile device. The cover plate has openings for the claw and the wireless charging module, allowing the claw and the wireless charging module to be exposed outside the receiving cavity through the cover plate. The two claws are used to clamp the mobile device by abutting against the two ends of the mobile device on the cover plate.

[0008] Preferably, the slider has a storage groove, and the left and right side walls of the storage groove have hinge mounting holes. The gripper is rotatably connected to the storage groove via a hinge. Below the hinge mounting holes, the bottom of the storage groove is recessed to form a gripper rotation clearance groove. When the gripper is parallel to the slider, the gripper abuts against the storage groove. When the gripper is perpendicular to the slider, the front wall of the gripper rotation clearance groove abuts against the bottom of the gripper.

[0009] Preferably, an elastic strip is provided on the front side of the storage groove, and the elastic strip extends along the front edge of the storage groove. When the gripper is parallel to the slider, the elastic strip engages with the gripper to fix the gripper on the storage groove.

[0010] Preferably, a torsion spring is provided in the hinge mounting hole, and the torsion spring is connected to the gripper and the hinge mounting hole respectively, and is used to rotate the gripper to be parallel to the slider by generating torque on the gripper.

[0011] Preferably, a notch is provided at the top of the front side wall of the gripper rotation clearance groove.

[0012] Preferably, the top of the spring mounting platform is provided with an insertion hole, and the bottom of the cover plate extends downward to form a positioning post corresponding to the insertion hole, the positioning post being used to insert into the insertion hole.

[0014] Preferably, the slide groove includes a plurality of grooves protruding from the receiving cavity, the grooves extending along the length of the receiving cavity, the slide groove leading into the spring mounting platform, and the spring being placed between adjacent grooves within the slide groove.

[0015] The main technical effects achieved by this utility model solution include:

[0016] The wireless power bank and its clamping structure provided by this utility model, by opening a receiving cavity under the cover plate, allows two clamping seats in the receiving cavity to stably clamp the mobile device, avoiding the problem of the mobile device detaching or misaligning from the wireless power bank. Compared with the prior art, this solution does not require additional magnetic components and achieves a more reliable clamping effect through mechanical structure, while maintaining the convenience of wireless charging and preventing the device from shifting or falling off during movement. It has the advantages of firmly fixing the device and being easy to use.

[0017] The gripper automatically adjusts its position using the spring force to adapt to mobile devices of different sizes.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0030] To avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not of great importance are omitted.

[0031] like Figure 1As shown, this utility model embodiment provides a wireless power bank, which includes a power bank housing 1, a wireless charging module 2, a clamping base 3, and a cover plate 4.

[0032] Combination Figure 2 As shown, the opening on the power bank housing 1 forms a downwardly recessed receiving cavity 10; the wireless charging module 2 is fixed in the receiving cavity 10;

[0033] There are two clamping seats 3, which are located on opposite sides of the wireless charging module 2 inside the receiving cavity 10. Each clamping seat 3 includes a gripper 31, a slider 32, a groove 33, a spring 34, and a spring mounting platform 35. The two spring mounting platforms 35 are fixed at the front and rear ends inside the receiving cavity 10, that is, at the two ends furthest apart along the length of the receiving cavity 10. The groove 33 and the spring 34 both extend along the length of the receiving cavity 10. One end of the spring 34 is connected to the spring mounting platform 35, and the other end of the spring 34 is connected to the slider 32. The gripper 31 is connected to the slider 32, and the slider 32 can drive the gripper 31 to slide along the groove 33.

[0034] The cover plate 4 is placed on the receiving cavity 10. The top surface of the cover plate 4 is used to place the mobile device. The cover plate 4 has a gripper opening 401 and a charging opening 402 to allow the gripper 31 and the wireless charging module 2 to pass through the cover plate 4 and protrude outside the receiving cavity 10. The two grippers 31 are used to clamp the mobile device by abutting against the two ends of the mobile device on the cover plate 4 respectively.

[0035] When charging a mobile device using the aforementioned wireless power bank, the two ends of the mobile device abut against the two grippers 31 respectively. The two sliders 32, under pressure, move along the front and rear ends of the slide groove 33. The springs 34 connected to the two spring mounting platforms 35 are compressed, and the elastic force provided by the springs 34 clamps the mobile device, thus achieving stable placement of the mobile device on the cover plate 4 and the wireless charging module 2, avoiding the problem of the mobile device detaching from or becoming misaligned with the wireless power bank during transport. The grippers 31 can automatically adjust their position through the elastic force of the springs 34 to adapt to mobile devices of different sizes. It should be noted that the size of the clamping base 3 and the distance between the two clamping bases 3 can be adjusted according to the actual size of the receiving cavity 10. The cooperation between the slide groove 33 and the sliders 32 ensures the smooth movement of the grippers 31, improving the reliability of the clamping. The charging position opening 402 on the cover plate 4 allows the wireless charging module 2 to directly contact the mobile device, ensuring charging efficiency and stability. Compared with existing technologies, this solution does not require additional magnetic components, achieving a more reliable clamping effect through a mechanical structure while maintaining the convenience of wireless charging.

[0036] Combination Figures 3 to 5 As shown, the slider 32 has a storage groove 321, and hinge mounting holes 322 are formed on the left and right side walls of the storage groove 321. The gripper 31 is rotatably connected to the storage groove 321 via hinges. Below the hinge mounting holes 322, the bottom of the storage groove 321 is also recessed to form a gripper rotation clearance groove 323. When the gripper 31 is parallel to the slider 32, the gripper 31 is in a horizontal state and abuts against the storage groove 321. The bottom of the receiving groove 321 prevents the front end of the gripper 41 from continuing to rotate downward. When the gripper 31 is perpendicular to the slider 32, the gripper 31 is in an upward upright state. The front wall 323a of the gripper rotation clearance groove 323 abuts against the bottom of the gripper 31. The front wall 323a of the gripper rotation clearance groove 323 prevents the bottom of the gripper 31 from continuing to rotate forward. The bottom of the receiving groove 321 and the front wall 323a of the gripper rotation clearance groove 323 cooperate to limit the rotation range of the gripper 31.

[0037] When using the wireless power bank, the user can move the gripper 31 from the gripper opening 401 of the cover plate 4 to flip the gripper 31 to an upright state that can hold the mobile device or a horizontal state that is stored in the groove.

[0038] This embodiment of the invention solves the problem of traditional fixed grippers 31 occupying space and affecting portability when not in use by using a rotatable gripper 31. When not needed to hold mobile devices, the gripper 31 can be rotated and stored in the groove of the slider 32; when needed, the gripper 31 can be quickly unfolded and held in a stable state. Compared with the prior art, this solution achieves a compact structure and improved portability while maintaining the gripping function, avoiding the risk of collision damage to the gripper 31 during transportation, and the hinge connection ensures the reliability and durability of the gripper 31's rotation.

[0039] like Figure 6 As shown, as one embodiment of the gripper 31, to enable it to remain stable in a lateral state, an elastic strip 324 is provided on the front side of the storage groove 321. The elastic strip 324 extends along the front edge of the storage groove 321. When the gripper 31 is parallel to the slider 32, the elastic strip 324 engages with the gripper 31 to fix the gripper 31 on the storage groove 321.

[0040] As another embodiment of the gripper 31, a torsion spring is provided in the hinge mounting hole 322. The torsion spring is connected to the gripper 31 and the hinge mounting hole 322 respectively, and is used to rotate the gripper 31 to be parallel to the slider 32 by generating torque on the gripper 31.

[0041] The top of the front side groove wall 323a of the gripper rotation clearance groove 323 has a notch 3230. The notch 3230 provides more space for the user to move the gripper 31 and provides more positions for the gripper to be installed, so as not to affect its rotation. The notch 3230 is preferably set as an arc notch.

[0042] The gripper 31 has a charging cable clearance opening, which divides the front end of the gripper 31 into two forward-extending claw bodies. The charging cable clearance opening is an opening structure that penetrates the thickness of the front end of the gripper and extends along the length of the gripper 31, dividing the front end of the gripper 31 into two independent and elastically deformable claw bodies. Furthermore, an anti-slip rubber layer can be provided at the end of the claw body, and the surface of the rubber layer has staggered raised textures.

[0043] The top of the spring mounting platform 35 is provided with an insertion hole 350, and the bottom of the cover plate 4 extends downward to form a positioning post corresponding to the insertion hole 350. The positioning post is used to be inserted into the insertion hole 350.

[0044] This technical solution achieves rapid positioning and fixation of the cover plate 4 and the spring mounting platform 35 through the insertion and engagement of the insertion hole 350 and the positioning post, preventing the cover plate 4 from shifting or loosening during movement. Specifically, after the positioning post is inserted into the insertion hole 350, it restricts the horizontal displacement of the cover plate 4, ensuring precise alignment between the clamping seat 3 and the opening of the cover plate 4, thereby guaranteeing that the gripper 31 is always aligned with both ends of the mobile device.

[0045] The cover plate 4 is a transparent plate. The transparent plate can be made of materials with good light transmittance, such as polycarbonate, acrylic, or tempered glass. By using a transparent material for the cover plate, the user can directly observe the working status of the clamping seat 3 inside the receiving cavity 10 during charging.

[0046] The slide groove 33 includes multiple protruding grooves 331 formed on the receiving cavity 10, the grooves 331 extending along the length of the receiving cavity 10. The slide groove 33 opens into the spring mounting platform 35, and the spring 34 is placed between adjacent grooves 331 within the slide groove 33. The arrangement of multiple grooves 331 reduces the vibration amplitude of the slider 32 during rapid movement, ensuring that the gripper 31 can smoothly clamp the mobile device. By extending the slide groove 33 into the interior of the spring mounting platform 35 to form a continuous channel, the movement trajectory of the spring 34 is made more stable. The spring 34 is completely confined within the slide groove 33, preventing twisting or displacement during extension and retraction.
