Description

Technical Field

[0001] The utility model relates to the technical field of screen projection devices, and in particular to a vehicle-mounted mobile phone screen projection device. Background Art

[0002] The in-car mobile phone screen projection device is a device specially designed to project the content of the mobile phone screen onto the screen of the in-car entertainment system in the car. This device allows drivers and passengers to enjoy the content on the mobile phone in the car, such as navigation, music, video, etc., without directly operating the mobile phone.

[0003] At present, the existing in-vehicle mobile phone projection devices cannot prevent the mobile phone from accidentally falling off when the vehicle encounters bumps during driving, which reduces the safety and convenience of the driving process. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that it is impossible to avoid the accidental drop of the mobile phone due to the bumps encountered by the vehicle during driving, thereby reducing the safety and convenience during driving, and to propose a vehicle-mounted mobile phone screen projection device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A vehicle-mounted mobile phone screen projection device, comprising:

[0007] A cup holder socket, wherein a top seat is fixedly arranged on the top of the cup holder socket, two mounting frames are symmetrically fixedly arranged on one side of the top seat, a same rotating rod is rotatably arranged inside the two mounting frames, and a supporting plate is fixedly arranged on one side of the rotating rod;

[0008] An adjusting mechanism is arranged on the rotating rod and the mounting frame and is used to limit and adjust the tilt angle of the supporting plate;

[0009] The clamping assembly is arranged on the supporting plate and is used for clamping the mobile phone.

[0010] In a possible design, the adjustment mechanism includes a gear fixedly set on a rotating rod extending to one end of the outside of the mounting frame, a rotating shaft is rotatably set on one side of the mounting frame, a torsion spring is sleeved on the outside of the rotating shaft, a clamping block is fixedly set on the outside of the rotating shaft, the clamping block can be disengaged from the gear, one end of the torsion spring is fixedly connected to the mounting frame, and the other end of the torsion spring is fixedly connected to the clamping block.

[0011] In a possible design, the clamping assembly includes four sliding rods respectively slidably arranged on both sides of the support plate, the ends of the four sliding rods that are close to each other are fixed with the same tension spring, the ends of the two sliding rods on the same side are fixed with the same clamping plate, and the outsides of the four sliding rods are fixed with limit blocks.

[0012] In one possible design, a connecting column is fixedly provided inside the top seat, a swivel is provided outside the connecting column, a clockwork spring is provided outside the connecting column and inside the swivel, the inner end of the clockwork spring is fixedly connected to the connecting column, the outer end of the clockwork spring is fixedly connected to the inner wall of the swivel, and a wiring harness is wound around the outside of the swivel.

[0013] In one possible design, one end of the wiring harness is electrically connected to a USB plug, and the other end of the wiring harness is electrically connected to a mobile phone plug. A placement groove for placing the USB plug is provided on one side of the top seat, and a placement hole for placing the mobile phone plug is provided on the top of the top seat.

[0014] In a possible design, two brackets are symmetrically fixedly provided on the top of the support plate, and a rubber block is fixedly provided on the bottom of the support plate.

[0015] In a possible design, a plurality of evenly distributed through holes are provided on the top of the support plate to facilitate heat dissipation of the mobile phone.

[0016] In this application, when starting to use, first insert the device into the cup holder near the central armrest box in the vehicle through the cup holder socket, and ensure that the cup holder socket is firmly fixed therein, then insert the mobile phone between the two clamping plates through the oblique opening on the clamping plate and place it on the pallet, and ensure that the bottom of the mobile phone is firmly in contact with the pallet. During the process of inserting the mobile phone between the two clamping plates, the elastic force of the tension spring automatically adapts to drive the sliding bars on both sides to move closer to the middle. During the movement of the sliding bar, the clamping plate is driven to clamp the two sides of the mobile phone, and the limit block ensures that the sliding bar will not separate from the pallet during the movement. Then check whether the mobile phone is firmly clamped to avoid the mobile phone falling due to bumps in the vehicle during driving;

[0017] If the angle of the mobile phone needs to be adjusted to meet different viewing needs, first make sure that the tray is in the initial state, then pull the tray or the mobile phone so that the tray rotates and unfolds in a fan shape on the mounting frame through the rotating rod. When the rotating rod rotates, the gear on it will rotate accordingly. When the gear rotates, the card block will drive the rotating shaft to rotate at the same time. When the card block rotates, the torsion spring is compressed, and at the same time, the rotation of the card block will cause it to disengage from the gear. Continue to pull the tray or the mobile phone until it rotates to the desired angle, then pull the tray or the mobile phone back slightly, at this time the torsion spring releases its elastic force, pushing the card block to re-engage with the gear, thereby locking the tray at the selected angle;

[0018] Then pull out the USB plug from the placement slot of the top seat and insert it into the vehicle's USB port for power supply, then pull out the mobile phone plug from the placement hole of the top seat and insert it into the charging and data transmission port of the mobile phone. When the USB plug is pulled out, the wiring harness will be pulled out synchronously. When the wiring harness is pulled, the swivel will rotate to release the wiring harness until the wiring harness is pulled to a suitable length. In this process, the spring will be deformed by the force. The wiring harness is kept neat and orderly through the automatic rewinding function of the swivel and the spring to avoid being messy. The spring ensures that the wiring harness can be automatically wound around the swivel when not in use.

[0019] Then start the vehicle's display or navigation system, confirm that the phone is correctly connected to the vehicle's display or system (such as CarPlay or CarLife), and adjust the display settings of the car's display according to the compatibility of the vehicle and phone to ensure the clarity and color accuracy of the projection content. After the projection is completed, first disconnect the phone plug from the phone and put it back into the placement hole of the top seat. Similarly, unplug the USB plug from the vehicle's USB port and put it back into the placement slot.

[0020] The utility model has the following beneficial effects:

[0021] In the utility model, the support plate is flexibly rotated on the mounting frame through the rotating rod by setting the adjustment mechanism, and the cooperation between the gear and the card block and the elastic force of the torsion spring are used to achieve accurate adjustment and stable locking of the angle, so that the user can conveniently and reliably adjust the angle of the mobile phone to any desired position to meet different viewing needs;

[0022] In the utility model, by setting the clamping assembly, when the mobile phone is inserted between the two clamping plates, the elastic force of the tension spring automatically adapts and drives the slide bars on both sides to move closer to the middle. During the movement of the slide bar, the clamping plates are driven to clamp the two sides of the mobile phone, so that the mobile phone can be firmly clamped on the support plate, effectively preventing the mobile phone from accidentally falling during bumpy driving, thereby improving the safety and convenience during driving.

[0023] The utility model can ensure that the mobile phone can be firmly clamped on the supporting plate through the arrangement of the clamping assembly, effectively preventing the mobile phone from accidentally falling off during bumpy driving, and improving the safety and convenience during driving.
