Description

Technical Field

[0001] The invention relates to a vehicle-mounted flat-panel charging base device and a working method thereof. Background Art

[0002] With the development of automobiles, the functions in the car are becoming more and more diversified. Some models are designed with a liquid crystal tablet on the rear center armrest, which can be used to facilitate rear passengers to control and adjust the sound, temperature, humidity, atmosphere lights, etc. in the car to meet the needs of different times. In the prior art, the liquid crystal tablet is generally placed in the slot on the surface of the center armrest for storage and charging. The liquid crystal panel is generally limited in the slot by a buckle structure, but the existing buckle structure is unlocked by swinging through mechanical control, that is, manually pressing a button to directly drive the movable shaft and the movable hook of the buckle structure to swing to unlock. This direct mechanical unlocking method requires manual use of greater force, which is relatively inconvenient.

[0003] Secondly, the two ends of the LCD panel are limited in the slot of the charging base by the buckle structure, one side of which is fixed, and the other side is a movable buckle E1 that can be rotated to unlock or lock. However, the current buckle structure design is unreasonable, such as Fig.14 As shown, the rotation point E2 of the existing active buckle is generally set to the left side of the contact surface E3 of the active buckle and the flat plate E4. Such a buckle structure design causes the flat plate to swing up and down due to the force when the car is driving on a bumpy road, which easily causes the active buckle to rotate to the left and unlock after being forced, so that the card slot of the flat plate is separated from the active buckle, thereby causing the flat plate to fall, which is not conducive to use. Summary of the invention

[0004] The present invention improves the above-mentioned problem, that is, the technical problem to be solved by the present invention is to provide a vehicle-mounted tablet charging base device and a working method thereof, which has a simple structure and is easy to use, while effectively avoiding the problem that the movable buckle is easily unhooked.

[0005] The present invention is constructed as follows: it includes a charging base and a tablet arranged in a charging groove on the upper surface of the charging base; fixed buckles and movable buckles for limiting the tablet are respectively arranged on both sides of the charging base; the movable buckle is rotatably matched with the charging base via a movable shaft; a hook portion is arranged on the upper part of the movable buckle; the top surface of the hook groove of the hook portion is a pressing surface; the center line of the pressing surface coincides with the center line of the movable shaft or is on the right side of the center line of the movable shaft; the lower side of the movable buckle is pressed by a bidirectionally rotatable special-shaped wheel body and then rotated along the movable shaft to unlock.

[0006] Furthermore, a mounting plate is provided in front of the special-shaped wheel body, and a motor for driving the special-shaped wheel body to rotate is installed in front of the mounting plate; an arc-shaped limiting groove is provided on the mounting plate, and a limiting protrusion is provided in front of the special-shaped wheel body, which extends into the arc-shaped limiting groove and can move along the arc-shaped limiting groove.

[0007] Furthermore, the special-shaped wheel body includes a rotating part and a pressing part arranged below the rotating part, and sensing parts are arranged on both sides above the rotating part, and the two sensing parts are staggered front and back.

[0008] Furthermore, two fixed buckles are arranged at the front and rear; two movable buckles are arranged at the front and rear, and the two movable buckles are connected via a movable shaft; a swing arm is arranged at the lower side of the movable buckle located in the front, and the swing arm extends to the upper side of the pressing part of the special-shaped wheel body. When the special-shaped wheel body rotates clockwise, the pressing part of the special-shaped wheel body drives the swing arm to swing upward along the movable shaft; a limiting strip is arranged at the lower side of the movable buckle located at the rear, and the limiting strip is limited to a limiting groove arranged below the base.

[0009] Furthermore, coil springs are provided at the front and rear ends of the movable shaft to keep the movable buckle in a locked state.

[0010] Furthermore, two travel switches are arranged at the front and rear of the side of the shaped wheel body away from the movable buckle. The travel switch located in the front cooperates with the sensing part of the shaped wheel body located in the front, and the travel switch located in the rear cooperates with the sensing part of the shaped wheel body located in the rear.

[0011] Furthermore, a telescopic groove is provided on the inner bottom surface of the charging slot of the charging base, and a top block extending out of the inner bottom surface of the charging slot is provided in the telescopic groove. The top block can be telescopically moved up and down along the telescopic groove, and a spring is provided between the top block and the inner bottom surface of the telescopic groove.

[0012] Furthermore, slots are respectively provided on both sides of the charging slot, and the hook portion of the movable buckle and the fixed buckle extend from the slots into the charging slot to cooperate with the slots provided on both sides of the tablet.

[0013] Furthermore, a contact charger is provided on the bottom surface of the charging slot, and the contact charger is in contact and communication with a charging area provided on the lower surface of the flat panel.

[0014] Furthermore, the working method of the vehicle-mounted tablet charging base device is that when the tablet is in the charging slot of the charging base and needs to be taken out, the motor is controlled to rotate to drive the special-shaped wheel body to rotate clockwise, and the pressing portion of the special-shaped wheel body drives the swing arm to swing upward along the movable axis, and simultaneously drives the movable buckle to swing left along the movable axis, so that the movable buckle is disengaged and unlocked from the slot of the tablet.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention is cleverly designed, easy to use, labor-saving and lightweight. It does not require a large force to unlock and access the tablet. It only needs to press the unlocking switch to control the motor to drive the special-shaped pressure wheel to rotate forward. The pressing part of the special-shaped pressure wheel pushes the swing arm of the movable buckle upward, causing the movable buckle to rotate along the movable axis, so that the upper part of the movable buckle is disengaged from the slot on the side of the tablet. At this time, the top block is pushed upward under the elastic force of the spring, and the tablet is lifted out of the charging slot. At this time, the motor drives the special-shaped pressure wheel to reverse and reset, and the movable buckle is reset to wait for the next unlocking operation; when the tablet is placed in the charging slot of the charging base, the slot on one side of the tablet is aligned with the fixed buckle, and the other side of the tablet is pressed downward so that the slot on the other side of the tablet is snapped into the movable buckle. At this time, the charging area of ​​the tablet is also in contact with the contact charger of the charging base for charging. (2) By setting the rotation point of the active buckle on the right side of the active buckle pressing surface or on the same straight line, when the vehicle is driving and the flat plate is pushed upward due to road conditions, the active buckle will not be easily forced to swing to the left to cause the hooking problem. When the active buckle is pushed upward by the flat plate, when the rotation point is set on the right side of the active buckle pressing surface, the active buckle will be forced to swing to the right, which will make the lock more secure, thereby effectively preventing the active buckle from being forced to swing to the left and solving the problem of the flat plate easily falling out.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1: Figure 1-13 As shown, in an embodiment of the present invention, a vehicle-mounted tablet charging base device is provided, comprising a charging base 1 and a tablet 12 arranged in a charging slot 101 on the upper surface of the charging base, wherein fixed buckles 2 and movable buckles 3 for limiting the tablet are respectively provided on both sides of the charging base, wherein the movable buckle is rotatably matched with the charging base via a movable shaft 4, the movable buckle is fixedly connected to the movable shaft, the movable shaft passes through the charging base and rotatably matches with the charging base, a hook portion 31 is provided on the upper portion of the movable buckle 3, and the top surface of the hook groove 32 of the hook portion is a pressing surface 321, when the tablet is inserted into the charging slot, the pressing surface of the hook portion presses the slot 121 of the tablet 12, and the center line A of the pressing surface coincides with the center line B of the movable shaft or is on the right side of the center line B of the movable shaft, and the lower side of the movable buckle is pressed by a bidirectionally rotatable special-shaped wheel body 5 and rotates along the movable shaft to unlock.

[0019] The present invention sets the rotation point of the active buckle on the right side of the active buckle pressing surface or on the same straight line, so that when the vehicle is driving and the flat plate is pushed upward due to road conditions, the active buckle is not easy to swing to the left to cause the hooking problem.

[0020] During the vehicle formation process, especially when driving on some places with poor road conditions, the vehicle will vibrate, causing the flat panel to swing up and down; when the movable buckle is subjected to the upward force of the flat panel, since the rotation point is set on the right side of the pressing surface of the movable buckle, the movable buckle will be forced to swing to the right side along the movable axis, which will lock it more securely, thereby effectively preventing the movable buckle from swinging to the left under the force, producing a self-locking effect, and solving the problem of the flat panel easily falling off.

[0021] It is worth noting here that the movable buckle swings to the left for unlocking the movable buckle, and the movable buckle swings to the right for locking the movable buckle.

[0022] In the embodiment of the present invention, a mounting plate 6 is arranged in front of the special-shaped wheel body 5, and a motor 7 for driving the special-shaped wheel body to rotate is installed in front of the mounting plate, and the output shaft of the motor is connected to the special-shaped wheel body.

[0023] In order to limit the rotation angle of the special-shaped cam, the mounting plate is provided with an arc-shaped limiting groove 601, and the front of the special-shaped wheel body is provided with a limiting protrusion 54, which extends into the arc-shaped limiting groove and can move along the arc-shaped limiting groove.

[0024] In the embodiment of the present invention, the special-shaped wheel body 5 includes a rotating part 51 and a pressing part 52 arranged below the rotating part, and sensing parts 53 are arranged on both sides above the rotating part, and the two sensing parts are staggered front and back; the above-mentioned rotating part and the pressing part are integrated; the above-mentioned rotating part and the pressing part are in an 8-like shape as a whole; the sensing part is arc-shaped.

[0025] In the embodiment of the present invention, two fixing buckles are provided at the front and rear, and each fixing buckle is locked on the charging base via a fixing bolt 8.

[0026] There are two movable buckles at the front and back, and the two movable buckles are connected via a movable shaft 4; a swing arm 33 is fixed to the lower side of the movable buckle 3 located in the front, and the swing arm extends to the upper side of the pressing part of the special-shaped wheel body. When the special-shaped wheel body rotates clockwise, the pressing part of the special-shaped wheel body drives the swing arm to swing upward along the movable shaft; a limiting strip 34 is provided at the lower side of the movable buckle located at the rear, and the limiting strip is limited to the limiting groove 102 set below the base; the swing arm and the movable buckle are integrated.

[0027] The setting of the limiting strip and the limiting groove can prevent the other movable buckle from shifting when rotating with the movable shaft, thereby playing a limiting role in the front and rear positions.

[0028] When one of the movable buckles is driven by the special-shaped cam to swing, the other movable buckle also swings synchronously under the action of the movable shaft.

[0029] In the embodiment of the present invention, coil springs 9 are provided at the front and rear ends of the movable shaft to lock the movable buckle; one end of the coil spring is connected to the charging base, and the other end of the coil spring is connected to the movable buckle.

[0030] In the embodiment of the present invention, a telescopic groove 103 is provided on the inner bottom surface of the charging slot 101 of the charging base, and a top block 104 extending from the inner bottom surface of the charging slot is provided in the telescopic groove, and the top block can be telescopically moved up and down along the telescopic groove, and a spring 105 is provided between the top block and the inner bottom surface of the telescopic groove; the telescopic groove and the charging slot are connected through a through opening 106, the upper part of the top block cooperates with the through opening and extends outward through the through opening, and the width of the lower part of the top block is smaller than the width of the upper part of the top block and the through opening, thereby preventing the top block from falling out and playing a limiting role.

[0031] In the initial state, the top block protrudes from the inner bottom surface of the charging slot. When the tablet is installed in the charging slot, the top block is pressed into the telescopic slot. After the movable buckle is unlocked, the spring drives the top block to push up under the elastic force of the spring, so that the tablet can be removed from the charging slot for easy removal. In the process of the spring bouncing up, since the movable buckle on one side of the charging slot is unlocked and the fixed buckle side is still in a locked state, when the spring bounces up, it generally drives the side of the tablet close to the movable buckle to move slowly upward, and the tablet becomes inclined, that is, the side of the tablet close to the movable buckle is at a high place, and the side of the tablet close to the fixed buckle is at a low place.

[0032] In the embodiment of the present invention, slots 107 are respectively provided on both sides of the charging slot, and the hook portion of the movable buckle and the fixed buckle are extended from the slots into the charging slot to cooperate with the slots provided on both sides of the tablet.

[0033] In the embodiment of the present invention, the upper surface of the side of the hook portion of the movable buckle close to the tablet is an inclined surface, and the inclined surface is inclined from the upper left to the lower right, so that the tablet can be smoothly inserted into the slot of the tablet when pressed down; the pressing surface of the hook portion close to the tablet is a flat surface to prevent the tablet from easily falling out after being inserted.

[0034] In the embodiment of the present invention, when working: (1) when the tablet needs to be taken out, the unlocking switch is operated, and the special-shaped wheel body is driven to rotate clockwise by controlling the rotation of the motor, and the pressing part of the special-shaped wheel body drives the swing arm to swing upward along the movable axis, and simultaneously drives the movable buckle to swing leftward along the movable axis, so that the movable buckle is disengaged from the slot of the tablet and unlocked. At this time, the top block moves upward under the elastic force of the spring, and pushes one side of the tablet out of the charging slot of the charging base, so as to facilitate the use of the tablet; then the motor drives the special-shaped wheel body to reset, and the movable buckle is also reset to the locked state under the action of the coil spring, waiting for the next unlocking operation. (2) When the tablet is used up and needs to be stored and charged, the slot on one side of the tablet is aligned with the fixed buckle and locked, and the other side of the tablet is pressed downward so that the slot on the other side of the tablet is locked into the movable buckle. At this time, the tablet is limited in the charging slot of the charging base, and the charging area of ​​the tablet is just in contact with the contact charger of the charging base for charging.
