[0002] In daily life, people often use phone stands to solve the problem of phones not being supported when placed on a table. Currently, commonly used phone stands generally consist of a tray and a base plate, which are rotatably connected. When in use, the phone is placed on the tray, and a limiting device holds the tray at a specific angle. However, in actual use, existing phone stands are only for supporting the phone on a table. They are inconvenient to use in places like kitchens or cars where there is no table for a stand, resulting in poor performance. Moreover, in dimly lit places such as cars and kitchens, people sometimes receive video calls from others. When talking to friends, the dim lighting often makes video calls of poor quality, which is not conducive to communication. Summary of the Invention

The driving gears are all fixedly connected to both sides of the middle of the outer periphery of the rotating shaft. A coil spring is fixedly connected to the middle of the outer periphery of the rotating shaft. A limit ring is provided on the side of the driving gear that is furthest away from the shaft.
[0009] Preferably, telescopic rods are slidably connected to the front and rear parts of both sides of the back plate, and the telescopic rods are fixedly connected to each other by springs. A clamp is fixedly connected to the opposite end of each telescopic rod, and a connector is fixedly connected to the middle of one end of the back plate. The end of the connector away from the back plate is rotatably connected to a support plate through a damping rod.
[0010] Preferably, an opening is provided on both sides of the rear of the back panel, and a groove is provided in the middle of the inner sidewall of each opening. A locking strip is rotatably connected inside each groove, and the locking strip is rotatably connected to the end of the telescopic arm away from the Bluetooth speaker.

One end of each strap is fixedly connected to the rotating shaft, and the end of each strap away from the rotating shaft is fixedly connected to a fixing strip two. The fixing strip two is set inside the opening three, and the opening three is set on both sides of the rear part of the bottom end of the base.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. In normal use, the phone can be placed on the back panel. The support arm can be opened first, and its angle can be adjusted to adjust the viewing angle. After prolonged use, the cooling fan can be activated to dissipate heat, preventing overheating and damage, thus promoting long-term use. Simultaneously, the cooling fins, with multiple through-holes, facilitate ventilation and heat dissipation for the cooling fan, further enhancing practical use.
[0016] 2. When using the phone in a car or while exercising, users can first pull out the clamps on both sides of the back panel, place the phone on the back panel, and then rotate the clamps to hold the phone in place on both sides. After releasing the clamps, the springs between the telescopic rods will fix the telescopic rods to the clamps. The clamps hold the phone in place on both sides, effectively preventing the phone from falling during movement and bumps, which is beneficial for practical use.
[0017] 3. First, the strap can be pulled out using fixing strip two. Depending on the diameter of the fixing point, the strap can be passed through fixing opening one at different points. Once the strap is secured, the push block can be moved towards the center. Guided by sliding groove three, the slider will move the L-shaped limiting rod. Because the end of the L-shaped limiting rod is locked inside the limiting groove, which has a concave cross-section with high ends and a low center, the L-shaped limiting rod will move fixing strip one upwards as it moves. When fixing strip one and the locking post move upwards, the end of the strap can be passed through fixing opening two. People can pull the straps to fix the bracket to a nearby fixed point, such as a steering wheel or water pipe. Once the bracket is fixed, the push block can be released. At this time, the return spring will, under its own rebound force, drive the slider and the L-shaped limit rod to reset. When the L-shaped limit rod resets, it will, under the guidance of the limit groove, drive the fixing strip to press down. The fixing strip can tighten and fix the straps, thus enabling the bracket to switch between flat and fixed point positions. This is beneficial for practical use and makes it convenient for people to use in the car or while cooking.
[0018] 4. When the strap is pulled outward, the rotating shaft will rotate accordingly. When the rotating shaft rotates, it will drive the transmission gear to rotate synchronously through the drive gear. When the transmission gear rotates, it will drive the driven gear to rotate. The driven gear can drive the fixed shaft to rotate, thereby opening the rotating base and the fill light strip to realize automatic fill light for the surrounding environment. When in use, the fill light strip and the rotating base can rotate, which makes it easy for people to adjust the angle of the fill light. This is beneficial for people to make video calls in dimly lit environments and effectively improves the call quality.
[0019] 5. After use, the pusher can be pushed to lift the fixing strip upwards, loosening the strap and contacting the bracket support. When the strap is loosened, the coil spring can drive the rotating shaft to reset, realizing the rewinding of the strap. At the same time, the drive gear and transmission gear can drive the driven gear to reset and rotate, realizing the automatic retraction of the fill light strip, which is beneficial to practical use.

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0031] like Figures 1-9 The multi-purpose mobile phone stand shown includes a stand base 1, which includes a base 104. Fixed seats 101 are fixedly connected to both sides of the top rear portion of the base 104. Support arms 102 are rotatably connected between the fixed seats 101 via damping rods. A Bluetooth speaker 103 is fixedly connected to one side of the top of the support arm 102. Telescopic arms 105 are slidably connected inside the support arm 102. A support mechanism 2 is rotatably connected to the end of the telescopic arm 105 away from the support arm 102. Lighting mechanisms 3 are provided on both sides of the top of the base 104. A fixing mechanism 4 is connected to the bottom rear side of the lighting mechanism 3 via a reset mechanism 5. The fixing mechanism 4 is located at the bottom of the base 104. During normal use, the user can place the mobile phone on the back panel 205. When in use, the user can first open the support arm 102 and adjust its angle to adjust the viewing angle of the mobile phone.
[0032] The support mechanism 2 includes a back plate 205, with a mounting port 207 in the middle of the back plate 205. A cooling fan 201 is installed in the middle of the mounting port 207. A cross-shaped fixing bracket 208 is fixedly connected to the rear of the cooling fan 201. The ends of the cross-shaped fixing bracket 208 are fixedly connected to the back plate 205. The cooling fan 201 has evenly distributed heat dissipation fins 202 on both the front and rear sides. The heat dissipation fins 202 are fixedly connected to the front and rear sides inside the mounting port 207. After long-term use, the cooling fan 201 can be turned on to dissipate heat from the phone, preventing the phone from being damaged due to overheating after a long period of use, which is beneficial for the long-term use of the phone. At the same time, the heat dissipation fins 202 can assist in the heat dissipation of the phone. The heat dissipation fins 202 have multiple through holes, which facilitate the ventilation and heat dissipation of the cooling fan 201, which is beneficial for practical use.
[0033] The supplementary lighting mechanism 3 includes two openings 301, which are located in the middle of both sides of the base 104. Each opening 301 contains a supplementary lighting strip 303. One end of each supplementary lighting strip 303 is rotatably connected to a rotating seat 302. The rotating seats 302 are fixedly connected to both ends of the fixed shaft 506. During use, the supplementary lighting strip 303 and the rotating seat 302 can rotate, which allows people to easily adjust the angle of the supplementary light. This is beneficial for people to make video calls in dimly lit environments and effectively improves the call quality.
[0034] The fixing mechanism 4 includes a fixing port 403, which is located at the bottom of the base 104. A fixing port 402 is located at the center of the front side of the bottom end of the base 104. A retaining strip 405 is fixedly connected to the bottom of both the fixing port 402 and the fixing port 403. A retaining post 401 is slidably connected to the top of the fixing port 402. The top of the retaining post 401 is fixedly connected to the bottom end of the fixing strip 406. The fixing strip 406 is slidably connected to the front part of the base 104. A limiting groove 410 is provided at the front of the fixing strip 406. L-shaped limiting rods 409 are slidably connected to both sides inside the limiting groove 410. At this point, people can first pull out the strap 505 through the fixing strip 414 and, according to the diameter of the fixing point, adjust... The strap 505 passes through the fixing opening 403 at different points. After the strap 505 is fixed, the push block 407 can be pushed towards the center. Under the guidance of the sliding groove 413, the slider 408 will drive the L-shaped limiting rod 409 to move. Since the end of the L-shaped limiting rod 409 is stuck inside the limiting groove 410, the cross-section of the limiting groove 410 is concave with high ends and low middle. When the L-shaped limiting rod 409 moves, it will drive the fixing strip 406 to move upward. When the fixing strip 406 and the locking post 401 move upward, the end of the strap 505 can be passed through the fixing opening 402. The strap 505 can be pulled to fix the bracket support 1 to the nearby fixing point.
[0035] The reset mechanism 5 includes a fixed shaft 506, which is located at the rear of the base 104. A driven gear 507 is fixedly connected to the middle of the outer periphery of the fixed shaft 506. Drive gears 504 are meshed on both sides of the lower rear end of the driven gear 507. The drive gears 504 are fixedly connected to both sides of the middle of the outer periphery of the fixed shaft 508. A drive gear 503 is meshed on the rear side of each drive gear 504. The drive gears 503 are fixedly connected to both sides of the middle of the outer periphery of the rotating shaft 509. A coil spring 502 is fixedly connected to the middle of the outer periphery of the rotating shaft 509. Limit rings 501 are provided on the side of each drive gear 503 that is furthest away from the shaft. Simultaneously, the strap 50... When the 5 is pulled outward, the rotating shaft 509 will rotate accordingly. When the rotating shaft 509 rotates, it will drive the transmission gear 504 to rotate synchronously through the driving gear 503. When the transmission gear 504 rotates, it will drive the driven gear 507 to rotate. The driven gear 507 can drive the fixed shaft 506 to rotate, thereby opening the rotating seat 302 and the fill light strip 303 to realize automatic fill light for the surrounding environment. When in use, the fill light strip 303 and the rotating seat 302 can rotate, which makes it convenient for people to adjust the angle of the fill light. This is beneficial for people to make video calls in dimly lit environments and effectively improves the call quality.
[0036] Telescopic rods 209 are slidably connected to both sides of the back plate 205, and the telescopic rods 209 are fixedly connected to each other by springs. The ends of the telescopic rods 209 that are far apart are fixedly connected to clamps 204. A connector 203 is fixedly connected to the middle of one end of the back plate 205. The end of the connector 203 that is far away from the back plate 205 is rotatably connected to a support plate 206 through a damping rod. When people need to use it in a car or while exercising, they can first pull out the clamps 204 on both sides of the back plate 205, place the phone on the back plate 205, and then rotate the clamps 204 to lock the phone in place on both sides.
[0037] The back panel 205 has openings 212 on both sides of the rear. The inner side wall of each opening 212 has a groove 210. Each groove 210 is rotatably connected to a locking strip 211. The locking strip 211 is rotatably connected to the end of the telescopic arm 105 away from the Bluetooth speaker 103. When the clamp 204 is released, the springs between the telescopic rods 209 can fix the telescopic rods 209 and the clamp 204. The clamp 204 can hold the two sides of the phone, thus fixing the phone and effectively preventing it from falling during movement and bumps, which is beneficial for actual use.
[0038] The L-shaped limiting rods 409 are all slidably connected inside the limiting port 412. Each limiting port 412 is provided with a sliding groove 413. Sliding sliders 408 are slidably connected to both sides inside the sliding groove 413. The sliding sliders 408 are all fixedly connected to the upper outer periphery of the L-shaped limiting rods 409. Each L-shaped limiting rod 409 is fixedly connected to a push block 407 at the top.
[0039] The top of each L-shaped limiting rod 409 is slidably connected to the inside of the second slide groove 404. The top of each slide groove 404 passes through the middle of the front side of the top of the base 104. Each push block 407 is slidably connected to the top of the base 104. Each end of each slider 408 is fixedly connected to a return spring 411. Each return spring 411 is located inside the third slide groove 413. When the bracket support 1 is fixed, the push block 407 can be released. At this time, the return spring 411 will drive the slider 408 and the L-shaped limiting rod 409 to reset under its own rebound force. When the L-shaped limiting rod 409 resets, it will drive the fixing strip 406 to press down under the guidance of the limiting groove 410. The fixing strip 406 can press and fix the strap 505, thereby realizing the conversion between the bracket support 1 being laid flat and fixed at the fixed point, which is beneficial to practical use and can be used by people in the car or while cooking.
[0040] Limiting rings 501 are fixedly connected to the outer periphery of rotating shaft 509. Straps 505 are wound around both sides of the outer periphery of rotating shaft 509. One end of each strap 505 is fixedly connected to rotating shaft 509. A fixing strip 414 is fixedly connected to the end of each strap 505 away from rotating shaft 509. The fixing strip 414 is located inside opening 415, which is located on both sides of the rear bottom of base 104. After use, push block 407 can be pushed inwards to lift fixing strip 406 upwards, loosening strap 505 and releasing it from the support bracket 1. When strap 505 is loosened, coil spring 502 can drive rotating shaft 509 to reset, rewinding strap 505. Simultaneously, drive gear 503 and transmission gear 504 can drive driven gear 507 to reset and rotate, automatically retracting supplementary light strip 303, which is beneficial for practical use.
[0041] Working principle:
[0042] During normal use, the phone can be placed on the back panel 205. The support arm 102 can be opened first, and its angle can be adjusted to adjust the viewing angle. After prolonged use, the cooling fan 201 can be activated to dissipate heat, preventing damage from overheating and promoting long-term use. The heat dissipation fins 202, with multiple through-holes, further aid in heat dissipation, facilitating ventilation for the cooling fan 201. When using the phone in a car or during exercise, the side plates 204 of the back panel 205 can be pulled outwards. After placing the phone on the back plate 205, the user can rotate the clamp 204 to secure it to both sides of the phone. When the clamp 204 is released, the springs between the telescopic rods 209 fix the telescopic rods 209 to the clamp 204. The clamp 204 holds the phone in place, effectively preventing it from falling during movement or bumps. This is beneficial for practical use. In dimly lit places such as cars or kitchens, people sometimes receive video calls. However, the poor lighting often results in poor video call quality, hindering communication. In such cases, the user can first pull out the strap 505 using the fixing strip 414, and then... With the diameter of the fixed point determined, the strap 505 is passed through the fixing opening 403 at different points. After the strap 505 is fixed, the push block 407 can be moved towards the center. Under the guidance of the sliding groove 413, the slider 408 will drive the L-shaped limiting rod 409 to move. Since the end of the L-shaped limiting rod 409 is stuck inside the limiting groove 410, the cross-section of the limiting groove 410 is concave with high ends and low middle, so that when the L-shaped limiting rod 409 moves, it will drive the fixing strip 406 to move upward. When the fixing strip 406 and the locking post 401 move upward, the end of the strap 505 can be passed through the fixing opening 402. The strap 505 can be pulled to fix the bracket support 1 to a nearby fixed point, such as a steering wheel. For water pipes, etc., after the bracket support 1 is fixed, the push block 407 can be loosened. At this time, the return spring 411 will drive the slider 408 and the L-shaped limit rod 409 to reset under its own rebound force. When the L-shaped limit rod 409 resets, it will drive the fixing strip 406 to press down under the guidance of the limit groove 410. The fixing strip 406 can realize the clamping and fixing of the strap 505, thereby realizing the conversion between the bracket support 1 being laid flat and fixed at the fixed point, which is beneficial to practical use and can be used conveniently in a car or while cooking. At the same time, when the strap 505 is pulled outward, the rotating shaft 509 will rotate accordingly. When the rotating shaft 509 rotates, it will drive the transmission gear 504 to rotate synchronously through the drive gear 503.When the transmission gear 504 rotates, it drives the driven gear 507 to rotate. The driven gear 507 then drives the fixed shaft 506 to rotate, thereby opening the rotating base 302 and the supplementary light strip 303, achieving automatic supplementary lighting for the surrounding environment. During use, the supplementary light strip 303 and the rotating base 302 can rotate, allowing for easy adjustment of the supplementary light angle. This is beneficial for video calls in dimly lit environments, effectively improving call quality. After use, the push block 407 can be pushed inwards, lifting the fixed strip 406 upwards and loosening the strap 505, thus releasing its fixation to the bracket support 1. Once the strap 505 is loosened, the coil spring 502 drives the rotating shaft 509 to reset, retracting the strap 505. Simultaneously, the driving gear 503 and transmission gear 504 drive the driven gear 507 to reset, automatically retracting the supplementary light strip 303, which is beneficial for practical use.
