Description

Technical Field

[0001] The utility model relates to a wireless charging device, in particular to a pull-out type wireless charging treasure. Background Art

[0002] A wireless power bank is a portable charging device used to wirelessly charge smart electronic products such as mobile phones and smart watches. In common wireless power banks, in order to charge different types of electronic devices such as mobile phones and smart watches at the same time, a mobile phone charging position and a smart watch charging position are generally set on the top surface of the wireless power bank. However, in order to avoid the mobile phone covering the top surface of the wireless power bank and blocking the watch charging position, the wireless power bank needs to be designed to be larger, which reduces portability. At the same time, when the wireless power bank is matched with the mobile phone at an angle, although it is convenient for the user to watch the mobile phone screen in this state, the smart watch cannot be charged at this time because the smart watch charging position is tilted. It can be seen that due to the structural limitation of the fixed charging position of the smart watch, the smart watch can only be charged when the wireless power bank is placed flat, and the charging use scenario is limited.

When the internal charging seat 32 and the sliding seat 33 are pushed into the sliding groove 31, the sliding seat magnet 330 and the rear end magnet 311 are magnetically matched. When the internal charging seat 32 and the sliding seat 33 are pulled outward relative to the sliding groove 31, the sliding seat magnet 330 and the front end magnet 310 are magnetically matched.

[0024] In the above structure, the main wireless charging module in the shell 30 can be used to charge the mobile phone, and the secondary wireless charging module in the internal charging seat 32 can be used to charge the smart watch or wireless earphones. The internal charging seat 32 is arranged in the slide groove 31 on the side of the shell 30 and the two are in a sliding connection, so that the internal charging seat 32 can be pushed and pulled relative to the shell 30 inside and outside, thereby hiding or pulling out the secondary wireless charging module. Based on this pulling and pulling structure setting, the position interference between the smart watch and the mobile phone can be avoided, which helps to reduce the product size of the wireless power bank, making it more portable. During use, when the internal charging seat 32 and the slide seat 33 are pushed into the slide groove 31, the internal charging seat 32 and the slide seat 33 are magnetically positioned by utilizing the magnetic matching relationship between the slide seat magnet 330 and the rear end magnet 311; similarly, when the internal charging seat 32 and the slide seat 33 are pulled outward relative to the slide groove 31, the internal charging seat 32 and the slide seat 33 are magnetically positioned by utilizing the magnetic matching relationship between the slide seat magnet 330 and the front end magnet 310, thereby realizing the positioning function of the push-pull position of the internal charging seat, which can ensure that the internal charging seat is reliably matched with the smart watch or wireless headset.

[0025] In order to make the magnetic positioning relationship more accurate and reliable, in the present embodiment, two upper and lower slide seat magnets 330 are provided in the slide seat 33, and the number of the front end magnet 310 and the rear end magnet 311 are both two.

[0026] As a preferred embodiment, a shaft rod 320 is formed at the end of the internal charging seat 32, a shaft sleeve 331 is provided on the sliding seat 33, the shaft rod 320 passes through the shaft sleeve 331 and the two are rotatably matched, a screw 332 is threaded on the end of the shaft rod 320, and a first spring 333 is sleeved on the shaft rod 320 for elastically abutting against the screw 332.

When the wireless power bank is supported in an upright or inclined state, the inner charging seat 32 can be adjusted to a flat state accordingly, so that the charging function of devices such as smart watches is not affected while charging the mobile phone. At the same time, based on the elastic force provided by the first spring 333, the inner charging seat 32 can have a certain rotation damping, which is conducive to axial positioning of the inner charging seat 32.

[0028] To facilitate wiring, in the present embodiment, a threading hole 321 is provided on the shaft rod 320 , and a wire connected between the secondary wireless charging module and the charging circuit board passes through the threading hole 321 .

This structure can not only shorten the extension length of the wire, but also avoid position interference between the wire and the internal structure of the slide groove 31, so that the electrical connection relationship and the pull-out connection relationship do not interfere with each other.

[0031] In order to locate the rotation position of the inner charging seat 32, in this embodiment, the root of the shaft 320 is provided with two symmetrically arranged external teeth 322, and the side of the sleeve 331 facing the inner charging seat 32 is formed with an annular end face teeth 336, and the external teeth 322 mesh with the annular end face teeth 336. Among them, this embodiment preferably adopts a matching mode of meshing the internal and external teeth, and this meshing relationship can reliably locate the angular position of the inner charging seat 32.

[0032] As a preferred embodiment, a stopper 323 is formed at one end of the inner charging seat 32 outside the slide slot 31 , and the stopper 323 is used to abut against the opening of the slide slot 31 .

A second spring 342 is provided on the back side of the shell 30, and the second spring 342 is used to apply elastic force to the contact block 340 to make the rounded contact head 341 elastically contact with the wavy recess 350.

[0035] In the above structure, based on the elastic abutment engagement relationship between the rounded abutment head 341 and the wavy notch 350, the rotation position of the rotating ring 35 can be engaged and positioned, and no matter the housing 30 is placed horizontally or obliquely, it can be supported in an oblique state by the support ring 36. At the same time, the matching structure between the second spring 342, the abutment block 340 and the wavy notch 350 is simple, easy to implement, and has a long service life.

[0036] In order to cover the connection between the wavy recess 350 , the abutment block 340 and the second spring 342 , in the present embodiment, a rear cover 37 is fixed to the back side of the shell 30 , and the rear cover 37 covers the outer sides of the wavy recess 350 , the abutment block 340 and the second spring 342 .
