Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted screens, and more specifically, it relates to a convenient taking and placing mechanism for vehicle-mounted screens. Background Art

[0002] With the pursuit of various forms of internal motion mechanisms in new energy vehicle models, the vehicle-mounted screen, which was originally a simple fixed PAD, can no longer meet the usage needs of users. The function of taking out the PAD needs to be added, but the convenience of taking out the PAD needs to be considered.

[0003] Currently, most of the industry fixes the PAD by magnetic attraction. However, it is difficult to take out the PAD using the magnetic attraction method. If the magnetic attraction force is too small, the PAD is likely to fall off. If the force is too strong, it is inconvenient to take out the PAD. Moreover, the sudden suction when the PAD is put in is likely to produce abnormal noises, resulting in a poor experience. Content of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A convenient taking and placing mechanism for vehicle-mounted screens includes a base. A screen bracket is rotatably connected to the base, and a vehicle-mounted screen is detachably connected to the screen bracket. A magnetic attraction bracket is arranged on the base, and a magnet block is fixed on the magnetic attraction bracket. The vehicle-mounted screen is fixed on the screen bracket by the magnetic attraction force of the magnet block. A driving component for driving the screen bracket to rotate is also arranged on the base. When the screen bracket rotates, the distance between the vehicle-mounted screen and the magnet block changes accordingly.

[0006] The utility model is further arranged as follows: The magnetic attraction bracket is rotatably connected to the screen bracket. When the screen bracket rotates, it drives the magnetic attraction bracket to move together. A screen frame is arranged around the vehicle-mounted screen on the base. A first limit block is arranged on the magnetic attraction bracket. When the first limit block moves to abut against the screen frame, the magnetic attraction bracket cannot continue to move outward following the screen bracket.

[0007] The utility model is further arranged as follows: A second limit block is arranged on the screen bracket, and the second limit block is used to abut against the magnetic attraction bracket, so that the screen bracket cannot continue to rotate outward.

[0008] The utility model is further arranged as follows: A screen rotating shaft is arranged on the base, and the screen bracket is rotatably connected to the inside of the base around the screen rotating shaft.

[0009] The utility model is further arranged as follows: A magnetic attraction rotating shaft is arranged on the magnetic attraction bracket, and a shaft sleeve is arranged on the screen bracket. The magnetic attraction rotating shaft penetrates into the shaft sleeve, so that the magnetic attraction bracket is rotatably connected to the inside of the screen bracket around the magnetic attraction rotating shaft.

[0010] The utility model is further configured as follows: the driving assembly includes a driving motor arranged on a base, the driving motor and the screen bracket are transmitted through a connecting rod structure, the connecting rod structure includes a first connecting rod fixed on an output shaft of the driving motor, the other end of the first connecting rod is rotatably connected to a second connecting rod, and the other end of the second connecting rod is rotatably connected to the screen bracket.

[0011] The utility model is further configured as follows: a first connecting rod rotating shaft is arranged at one end of the first connecting rod away from the driving motor, a second connecting rod rotating shaft is arranged on the screen bracket, and two ends of the second connecting rod rotate around the first connecting rod rotating shaft and the second connecting rod rotating shaft respectively.

[0012] The utility model is further configured as follows: a mounting groove is provided on the magnetic bracket, and the magnet block is embedded in the mounting groove.

[0013] Compared with the prior art, the utility model has at least the following advantages:

[0014] 1. The car screen is placed on the screen bracket and fixed by magnetic attraction. During normal use, the screen bracket fits with the magnet block on the magnetic bracket. The magnetic attraction is large and the car screen is installed stably. When the car screen needs to be taken out, the screen bracket is rotated away from the magnet block through the driving component to increase the distance between the car screen and the magnet block, thereby reducing the magnetic attraction. The car screen can be easily removed, and the car screen can be rotated out from the base, making it more convenient to take. When the car screen is placed on the screen bracket, the screen bracket rotates toward the magnet block to gradually increase the magnetic attraction, which also prevents the car screen from being suddenly sucked in by the strong suction, causing abnormal noise or even damage.

[0015] 2. The magnetic bracket is rotated and connected to the screen bracket, and the movement of the magnetic bracket is limited by setting a first limit block, so that when the screen bracket is rotated outward at a large angle so that the PAD can be easily removed, the gap between the screen bracket and the magnet block will not be too large, preventing the PAD from falling under its own weight.

[0016] 3. By setting a second limit block on the screen bracket, when the screen bracket and the magnetic bracket are separated at a certain angle, the second limit block will abut against the magnetic bracket and the drive motor will stop, so that the screen bracket cannot continue to rotate, and the separation distance between the screen bracket and the magnet block is accurately located, so that the magnetic attraction will not completely disappear, making it convenient to install the car screen.

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] A vehicle-mounted screen convenient taking and placing mechanism, as Figures 1 to 3 shown, includes a base 1, a screen bracket 2 is rotatably connected to the base 1, a vehicle-mounted screen 12 is detachably connected to the screen bracket 2, a magnetic absorption bracket 3 is further arranged on the base 1, a magnet block 4 is fixed on the magnetic absorption bracket 3, the vehicle-mounted screen 12 is fixed on the screen bracket 2 by the magnetic attraction of the magnet block 4, and a user can separate the vehicle-mounted screen 12 from the screen bracket 2 by using an external force to achieve detachable connection, and the interface on the back of the vehicle-mounted screen 12 is matched with the connector on the screen bracket 2.

[0028] As Figures 3 to 6As shown in the figure, a driving component 5 for driving the screen bracket 2 to rotate is further provided on the base 1. When the screen bracket 2 rotates, the distance between the vehicle-mounted screen 12 and the magnet block 4 changes accordingly, so that the magnetic attraction force of the magnet block 4 on the vehicle-mounted screen 12 changes. When the vehicle-mounted screen 12 is in the normal use state, the back surface of the screen bracket 2 fits against the magnet block 4.

[0029] The magnetic suction bracket 3 is rotatably connected to the screen bracket 2. Since the vehicle-mounted screen 12 is attracted to the magnet block 4 and the magnet block 4 is fixed to the magnetic suction bracket 3, when the screen bracket 2 rotates, it will drive the magnetic suction bracket 3 to move together. A screen frame 6 is arranged around the vehicle-mounted screen 12 on the base 1. The screen frame 6 limits the edge of the vehicle-mounted screen 12 to prevent the vehicle-mounted screen 12 from shifting. A first limit block 7 is arranged on the magnetic suction bracket 3. The first limit block 7 is integrally formed on the magnetic suction bracket 3. The end of the first limit block 7 protrudes upward in a hook shape. The first limit block 7 is used to abut against the screen frame 6, so that the magnetic suction bracket 3 cannot continue to move with the screen bracket 2. And the screen bracket 2 continues to rotate outward under the drive of the driving component 5, so that the distance between the vehicle-mounted screen 12 and the magnet block 4 on the magnetic suction bracket 3 increases.

[0030] Specifically, the magnetic suction bracket 3 is rotatably connected to the inside of the screen bracket 2. A magnetic suction rotating shaft is integrally formed at the bottom of the magnetic suction bracket 3. The magnetic suction rotating shaft protrudes from the left and right sides of the magnetic suction bracket 3. Bushings 10 are arranged on the left and right sides of the magnetic suction bracket 3 inside the screen bracket 2. The two ends of the magnetic suction rotating shaft are respectively inserted into the bushings 10 so that the magnetic suction bracket 3 is rotatably connected to the inside of the screen bracket 2 around the magnetic suction rotating shaft. When the screen bracket 2 rotates outward, the magnetic suction bracket 3 moves with the screen bracket 2. When the first limit block 7 abuts against the screen frame 6, the magnetic suction bracket 3 cannot continue to move outward. At this time, the screen bracket 2 continues to rotate outward under the action of the driving component 5 against the magnetic attraction force, and the magnetic suction bracket 3 rotates relative to the screen bracket 2 around the magnetic suction rotating shaft.

[0031] The screen bracket 2 needs to rotate outward by a large angle so that the user can conveniently remove the vehicle-mounted screen 12. Since the magnetic force is in an inverse-square relationship with the distance, if the gap between the magnet block 4 and the screen bracket 2 is too large, the magnetic force will drop severely, which will cause the vehicle-mounted screen 12 to overcome the magnetic attraction force and fall off under its own weight. Therefore, by rotatably connecting the magnetic suction bracket 3 to the inside of the screen bracket 2, it will first move outward with it. When the first limit block 7 abuts against the screen frame 6, the magnetic suction bracket 3 cannot continue to move outward and instead starts to rotate, forming a gap with the screen bracket 2. Thus, while the screen bracket 2 rotates outward by a large angle, the gap between the screen bracket 3 and the magnet block 4 will not be too large.

[0032] A second limit block 8 is provided on the screen bracket 2, and the second limit block 8 is used to abut against the magnetic bracket 3, so that the screen bracket 2 cannot continue to rotate outward. The second limit block 8 is integrally formed in the screen bracket 2 and is located above the magnetic bracket 3. The end of the second limit block 8 protrudes downward in a hook shape. When the first limit block 7 abuts against the screen frame 6, the screen bracket 2 continues to rotate outward. At this time, the magnetic bracket 3 and the screen bracket 2 rotate relative to each other until the second limit block 8 abuts against the top of the magnetic bracket 3, so that the screen bracket 2 cannot continue to rotate outward. At the same time, the driving component 5 stops driving, accurately controls the rotation stroke of the screen bracket 2, and avoids the complete disappearance of the magnetic attraction force between the vehicle-mounted screen 12 and the magnet block 4, causing the vehicle-mounted screen 12 to fall off.

[0033] Screen shafts 9 are provided in the base 1 and on both sides of the screen bracket 2 . The left and right sides of the screen bracket 2 are respectively sleeved on the screen shafts 9 , so that the screen bracket 2 is rotatable around the screen shafts 9 and connected to the base 1 .

[0034] The driving assembly 5 includes a driving motor 501 installed inside the base 1. The driving motor 501 and the screen bracket 2 are transmitted through a connecting rod structure. The connecting rod structure includes a first connecting rod 502 fixed on the output shaft of the driving motor 501. The first connecting rod 502 rotates synchronously with the output shaft of the driving motor 501. The other end of the first connecting rod 502 is also rotatably connected to the second connecting rod 503. The other end of the second connecting rod 503 is rotatably connected to the screen bracket 2. The driving motor 501 drives the screen bracket 2 to rotate around the screen rotation axis 9 through the connecting rod structure.

[0035] A first connecting rod 502 rotating shaft is provided at one end of the first connecting rod 502 away from the driving motor 501, and a second connecting rod 503 rotating shaft is provided on the screen bracket 2. The two ends of the second connecting rod 503 rotate around the first connecting rod 502 rotating shaft and the second connecting rod 503 rotating shaft respectively. In this embodiment, the screen rotating shaft 9, the magnetic rotating shaft, the first connecting rod 502 rotating shaft, the second connecting rod 503 rotating shaft and the output shaft of the driving motor 501 are all parallel to each other.

[0036] A mounting groove 11 is provided on the magnetic bracket 3 on the side facing the vehicle screen 12, the magnet block 4 is embedded in the mounting groove 11, the mounting groove 11 is protruded from the surface of the magnet block 4, and a clearance groove is provided on the side of the screen bracket 2 facing the magnet block 4. The part of the magnet block 4 protruding from the mounting groove 11 will penetrate into the clearance groove, so that the screen bracket 2 can fit with the magnetic bracket 3 and make the magnet block 4 closer to the vehicle screen 12.

[0037] The working process of the utility model is as follows:

[0038] When it is necessary to remove the in-vehicle screen 12, the driving motor 501 drives the screen bracket 2 to rotate outward. When the first limiting block 7 abuts against the screen frame 6, the magnetic suction bracket 3 cannot move outward continuously. At this time, the screen frame 6 continues to rotate outward against the magnetic suction force, causing the magnetic suction bracket 3 and the screen bracket 2 to rotate relative to each other, creating a gap between the magnet block 4 and the screen bracket 2, and the magnetic suction force decreases. Then the user can easily remove the in-vehicle screen 12;

[0039] When it is necessary to install the in-vehicle screen 12, first rotate the screen bracket 2 out as in the above steps. Place the in-vehicle screen 12 on the screen bracket 2. At this time, although there is a distance from the magnet block 4, the in-vehicle screen 12 can still be attracted by a relatively small magnetic suction force. Then the screen bracket 2 rotates inward until the in-vehicle screen 12 fits with the screen frame 6.

[0040] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included within the protection scope of the present invention.
