[0002] With the continuous advancement of technology, more and more mobile electronic devices, such as smartwatches and smartphones, are entering people's lives, greatly facilitating daily life and providing convenient services in various fields such as shopping malls and travel. However, battery life is often a concern when using smartphones and other mobile electronic products, thus creating a need for power banks with wireless charging capabilities. Most existing wireless charging power banks attach magnetically to the back of smartphones for charging. However, to improve the stability of the power bank, a phone case with a magnetic ring is required. Furthermore, using existing wireless charging power banks makes it difficult to use phone stands, resulting in inconvenience when watching videos or engaging in other activities. Utility Model Content
[0003] The purpose of this invention is to provide a portable power bank with wireless charging capabilities to solve the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A portable power bank with wireless charging capability includes a power bank housing. A wireless charging coil is fixedly disposed inside the power bank housing. A battery module is fixedly disposed at the bottom of the wireless charging coil. A PCB board is disposed at the bottom of the battery module. A charging port is fixedly connected to the end of the PCB board. Clamping plates are disposed on both sides of the power bank housing. A sliding post that is slidably embedded in and connected to the end of each clamping plate is fixedly connected to the end of the two clamping plates. A toggle block is fixedly connected to the end of the sliding post. A bottom support is fixedly connected to one side of the side wall of the power bank housing along the width direction.
[0006] Furthermore, two limiting rods that are slidably connected to the side walls of the two clamps are fixedly connected, and a tension spring that is fixedly connected to the end of the limiting rod is fixedly connected to the end of the power supply housing.
[0007] Furthermore, a silicone layer is fixedly connected to the inner sidewalls of the two clamps.
[0008] Furthermore, multiple indicator lights are fixedly connected at equal intervals on the side wall of the power supply casing, and a switch button is provided on one side of each indicator light.
[0009] Furthermore, two strip-shaped pillars are symmetrically fixedly connected to the bottom of the power supply casing, and a resistance block is slidably embedded in each of the two strip-shaped pillars. A compression spring is fixedly connected to the center of each resistance block.
[0010] Furthermore, each of the two strip columns is slidably fitted with an adjusting column, and a damping shaft is fixedly connected between the ends of the two adjusting columns. A support plate is rotatably connected to the outside of the damping shaft, and an anti-slip pad is fixedly connected to the bottom of the support plate. Multiple wavy grooves are equally spaced on the adjusting column, and the resistance block engages with the wavy grooves.
[0011] Furthermore, two limiting grooves are symmetrically opened on the adjusting column, and two stops that slide and engage with the limiting grooves are symmetrically fixedly connected to the inner wall of the strip column.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. When using, place the back of the phone against the side wall of the power bank casing, and abut the charging end of the phone against the base. Then, spread your fingers to drive the two toggle blocks away from each other, thereby causing the two sliding pillars to slide at the end of the power bank casing. After release, the tension spring will pull the limit rod and clamp to move quickly to the side of the phone. Thus, the two clamps can clamp the side wall of the phone, which can fix the phone in place during wireless charging. This eliminates the need for a phone case with a magnetic ring on the outside of the phone, preventing the phone and power bank from easily separating during charging and causing charging interruption. The inner wall of the clamp is provided with a silicone layer to prevent damage to the side of the phone when clamping.
[0014] 2. After placing the support plate on the table, rotate the two adjusting columns and the damping shaft to a suitable angle. Then, the two adjusting columns can be slid in the strip column. The sliding is limited by the stop block in the strip column and the limiting groove in the adjusting column. This makes it easy to adjust the support height of the power bank shell and the mobile phone. The compression spring in the strip column keeps pressing the resistance block. This keeps the resistance block engaged with the wave-shaped groove. After adjustment, the strip column is subjected to a certain resistance, thereby improving the stability of the mobile phone support. This allows the wireless charging power bank to also function as a mobile phone stand. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5In this embodiment of the present invention, a portable power bank with wireless charging capability includes a power bank housing 101, a wireless charging coil 102, a battery module 103, a clamping plate 109, and a sliding column 113. The wireless charging coil 102 is fixedly disposed inside the power bank housing 101. The battery module 103 is fixedly disposed at the bottom of the wireless charging coil 102. A PCB board 104 is disposed at the bottom of the battery module 103. A charging port 105 is fixedly connected to the end of the PCB board 104. Both sides of the power bank housing 101 are provided with... The clamping plates 109 each have a sliding post 113 fixedly connected to their ends, which is slidably embedded in the power supply housing 101. A toggle block 114 is fixedly connected to the end of each sliding post 113, causing the two sliding posts 113 to slide at the end of the power supply housing 101. After release, a tension spring 112 pulls the limiting rod 111 and the clamping plates 109 to move quickly towards the side of the phone, thus clamping the side wall of the phone. A base support 108 is fixedly connected to one side of the side wall of the power supply housing 101 along its width. Two limiting rods 111 are fixedly connected to the side walls of the two clamping plates 109, slidably connected to the power supply housing 101. A tension spring 112 is fixedly connected to the end of each limiting rod 111, also fixedly connected to the power supply housing 101. A silicone layer 110 is fixedly connected to the inner side wall of the two clamping plates 109, preventing damage to the side of the phone during clamping. Multiple indicator lights 106 are fixedly connected at equal intervals on the side wall of the power supply housing 101, and a switch button 107 is provided on one side of the indicator lights 106.
[0023] Specifically, during use, the back of the phone is placed against the side wall of the power bank casing 101, and the charging end of the phone is placed against the base 108. Then, by spreading the fingers, the two toggle blocks 114 are driven to move away from each other, thereby causing the two sliding pillars 113 to slide at the end of the power bank casing 101. After release, the tension spring 112 will pull the limit rod 111 and the clamping plate 109 to move quickly to the side of the phone. Thus, the two clamping plates 109 can clamp the side wall of the phone, which fixes the phone during wireless charging. There is no need to put a phone case with a magnetic ring on the outside of the phone, which prevents the phone and the power bank from easily separating during charging and causing charging interruption. The inner wall of the clamping plate 109 is provided with a silicone layer 110 to prevent damage to the side of the phone when clamping.
[0024] Example 1
[0025] like Figure 4-5As shown, in this embodiment, two strip-shaped columns 207 are symmetrically fixedly connected to the bottom of the power supply housing 101. A resistance block 209 is slidably embedded in each of the two strip-shaped columns 207, and a compression spring 210 is fixedly connected to the center of each resistance block 209. An adjusting column 204 is slidably sleeved in each of the two strip-shaped columns 207. A damping shaft 203 is fixedly connected between the ends of the two adjusting columns 204. A support plate 201 is rotatably connected to the outside of the damping shaft 203. An anti-slip pad 202 is fixedly connected to the bottom of the support plate 201. Multiple wavy grooves 205 are evenly spaced on the adjusting column 204, and the resistance block 209 engages with the wavy grooves 205. Two limiting grooves 206 are symmetrically provided on the adjusting column 204. When the two adjusting columns 204 are pulled out, they slide in the strip column 207. The sliding is limited by the engagement of the stop block 208 in the strip column 207 and the limiting groove 206 in the adjusting column 204. This makes it easier to adjust the support height of the power supply shell 101 and the mobile phone. Two stop blocks 208 are symmetrically fixed on the inner wall of the strip column 207 and slide and engage with the limiting groove 206.
[0026] In this embodiment, after placing the support plate 201 on the table, the two adjusting columns 204 and the damping shaft 203 are rotated to a suitable angle with the support plate 201. Then, the two adjusting columns 204 can be slid in the strip column 207. The sliding is limited by the stop block 208 in the strip column 207 and the limiting groove 206 in the adjusting column 204. This makes it easier to adjust the support height of the power supply shell 101 and the mobile phone. The compression spring 210 in the strip column 207 keeps pressing the resistance block 209. The resistance block 209 keeps engaging with the wave-shaped groove 205. Therefore, the strip column 207 is subjected to a certain resistance after adjustment, thereby improving the stability of the mobile phone support and enabling the wireless charging power supply to also function as a mobile phone stand.
