Description

Technical Field

[0001] The present invention belongs to the technical field of electronic equipment accessories manufacturing, and in particular, relates to a display screen flipping device and an assembly method thereof. Background Art

[0002] With the rapid development of intelligent vehicles and human-computer interaction technologies, the use of in-vehicle displays and displays for various smart devices is becoming increasingly widespread. Users' expectations for the user experience of displays are constantly improving. In different usage scenarios (such as driving, riding, and working), they need to flexibly adjust the display angle based on their body shape, position, and sitting posture to achieve the optimal viewing and operating angle. Currently, common display flip devices on the market have various technical drawbacks. Some devices use complex transmission structures, such as multi-stage gear transmissions and connecting rod mechanisms. This not only increases the number of parts and assembly difficulty, leading to increased production costs, but is also prone to transmission failures due to component wear and clearance, reducing the reliability and service life of the device. Some devices, while capable of flipping the display, lack effective cushioning and positioning measures, and are prone to shaking and collision noise during the flipping process, which not only affects the user experience but may also damage the display. This results in some occupants finding it difficult to operate or being unable to achieve the ideal display angle, failing to meet the needs of users in different positions and sitting postures. Summary of the Invention

[0003] The present invention is developed to solve the above-mentioned problems, and its purpose is to provide a display screen flipping device with a simple structure and stable transmission, and an assembly method thereof, which can adjust the force and angle of the display screen flipping to meet the usage needs of users of different body shapes and sitting in different positions. In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a display screen flipping device includes a fixed shell, a bracket and a display screen mounted on the bracket are arranged in the fixed shell, and the bracket is connected to a rotating mechanism.

[0004] The rotating mechanism includes a first gear, which is arranged on one side of the fixed housing. The first gear is connected to a gear bar, which is connected to the bracket, and the first gear is connected to a driving structure.

[0005] The driving structure includes a driving motor, which is arranged on one side outside the fixed housing. The driving motor is connected to a gear shaft, and the gear shaft is connected to the first gear.

[0006] Rotation pins are provided at both ends of the bracket, and one end of the rotation pin is provided in the fixed shell.

[0007] A damper is sleeved on the rotating shaft pin, a protective sleeve plate is arranged in the fixed shell, and the damper is located in the protective sleeve plate.

[0008] The gear bar is provided with a connecting hole, a spring is connected in the connecting hole, one end of the fixed shell is provided with an arc groove and a fixing hole, and one end of the spring passes through the arc groove and is arranged in the fixing hole.

[0009] The bracket includes a base plate, first protective plates are connected to both sides of the base plate, second protective plates are connected to both ends of the base plate, a first cavity is formed between the base plate, the first protective plate and the second protective plate, and the base of the display screen is arranged in the first cavity.

[0010] A triangular plate is provided at one end of the first protective plate, the triangular plate is connected to the bottom plate, a pin hole is provided on the triangular plate, and one end of the rotating shaft pin is located in the pin hole.

[0011] The fixed shell includes a first fixed plate, both ends of the first fixed plate are connected to the second fixed plate, both sides of the first fixed plate are provided with first flanging plates, and both sides of the second fixed plate are provided with second flanging plates.

[0012] A method for assembling a display screen flipping device comprises the following steps:

[0013] Step 101: Install the gear shaft in the fixed housing, install the first gear on the gear shaft, install the drive motor and connect it to the fixed housing, and connect the output shaft of the drive motor to the gear shaft;

[0014] Step 102, connect the display screen into the first cavity and connect the gear bar to the bracket;

[0015] Step 103: Install the damper into the protective cover plate, insert one end of the rotating shaft pin into the damper and fix it on the fixed shell, insert the other end of the rotating shaft pin into the pin hole, and then mesh the gear bar with the first gear;

[0016] Step 104: Fix one end of the spring in the connecting hole, and fix the other end of the spring in the fixing hole.

[0017] The technical effects of the present invention are as follows: a circular first gear meshes with a sector-shaped gear bar. The drive motor drives the first gear to rotate, meshing the first gear with the gear bar, causing the gear bar to rotate. The gear bar then drives the bracket to flip, which in turn drives the display screen to rotate around a rotating pin, completing the angle adjustment of the display screen. The transmission structure is simple and reliable, enabling precise control of the display screen's flip angle. A spring applies tension to the gear bar, ensuring a constant, tight fit between the gear bar and the first gear. This effectively eliminates idle travel during meshing between the gear bar and the first gear, preventing transmission lag and reducing collision noise, thereby improving the smoothness and quietness of the device's operation. A damper is mounted on the rotating pin to slow the bracket's flipping speed, preventing shaking or impact caused by rapid display screen flipping, protecting the display screen and internal structures, and extending the device's service life. Through the coordinated action of the drive motor's first gear, the gear bar, the bracket, and the spring, the device can meet the viewing and operating needs of users of different body types and in different seating positions on the vehicle, improving user convenience and comfort.

[0024] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0025] like Figures 1 to 4 As shown, a display screen flipping device includes a fixed housing 1, within which is disposed a bracket 2 and a display screen 3 mounted on the bracket 2. The bracket 2 is connected to a rotation mechanism 4. The fixed housing 1 is mounted on the vehicle and accommodates the bracket 2 and the display screen 3. The bracket 2 is screw-connected to the base of the display screen 3. The base of the display screen 3 is a separate PCBA box. Because the PCBA box and the display screen are separated into two parts, the PCBA box can be designed for displays of different sizes. This allows a single rotation mechanism to adapt to different display sizes, reducing development costs.

[0026] The display screen 3 is fixed on the bracket 2, and a rotating mechanism 4 is set in the fixed shell 1. The rotating mechanism 4 is connected to the bracket 2. The rotating mechanism 4 can drive the bracket 2 and the display screen 3 to flip, thereby realizing the flipping of the display screen 3, meeting the usage needs of users of different body shapes in different positions and different sitting postures, and improving the convenience and comfort of use.

[0027] The rotation mechanism 4 includes a first gear 401, which is disposed on one side of the fixed housing 1. The first gear 401 is connected to a gear bar 402, which is connected to the bracket 2. The first gear 401 is connected to the fixed housing 1 via a gear shaft 412. The first gear 401 is a circular gear that meshes with the gear bar 402. The gear bar 402 has a fan-shaped structure. The gear bar 402 is fixed to the bracket 2 via screws. The drive structure 41 can be a motor. The drive structure 41 drives the first gear 401 to rotate. The first gear 401 meshes with the gear bar 402. The rotation of the first gear 401 drives the gear bar 402 to rotate. The gear bar 402 drives the bracket 2 to flip. The display screen 3 is fixed to the bracket 2, and the bracket 2 drives the display screen 3 to flip. The angle of the display screen 3 is adjusted to meet the needs of users of different body shapes and sitting positions in different locations, thereby improving user convenience and comfort. Rotation is achieved through the meshing of a first gear 401 and a gear bar 402. This simple structure reduces the likelihood of problems, reduces component material costs, and reduces the production cycle and cost of the assembly process. The entire rotating mechanism 4 occupies a small space, making it suitable for certain compact flip screens. The simple structure allows for local adjustment of the spatial position of certain components: the drive motor 411, first gear 401, and gear bar 402 can be positioned on the right side as needed, or they can be positioned in the center, mounted directly below the display bracket, for local adjustment.

[0028] The drive structure 41 includes a drive motor 411, which is arranged on the outside of the fixed housing 1. The drive motor 411 is connected to a gear shaft 412, and the gear shaft 412 is connected to the first gear 401. The drive structure 41 includes a drive motor 411, which is fixed to the outside of the fixed housing 1 by screws. The drive motor 411 serves as the power source for flipping the entire display screen 3. The output shaft of the drive motor 411 is connected to the gear shaft 412. The fixed housing 1 has a pre-machined bearing mounting hole. The gear shaft 412 is press-fitted so that the gear shaft 412 passes through the inner ring of the bearing mounting hole. At the end of the gear shaft 412 that extends out of the fixed housing 1, it is splined to the first gear 401. The axial position of the first gear 401 is fixed by a nut to prevent it from moving on the shaft. The drive motor 411 can drive the first gear 401 through the gear shaft 412, and the first gear 401 rotates synchronously with the drive motor 411. The flipping control of the bracket 2 and the display screen 3 is achieved through the combined action of the driving motor 411 , the gear shaft 412 , the first gear 401 and the gear bar 402 .

[0029] A rotation pin 201 is provided at each end of the bracket 2, one end of which is disposed within the fixed housing 1. The rotation pin 201 is connected to the corners of the bracket 2, one end of which is movably disposed within the fixed housing 1. A drive motor 411 drives a first gear 401 to rotate, which engages with a gear bar 402, causing the gear bar 402 to rotate. The gear bar 402 then pushes the bracket 2 to flip, causing the bracket 2 to rotate the display screen 3 around the rotation pin 201, completing the angle adjustment of the display screen 3. After the display screen 3 flips to the target position, if it needs to be reset, the drive motor 411 can rotate it in the opposite direction, thereby driving the display screen 3 to rotate in the opposite direction around the rotation pin 201 to reset it.

[0030] A damper 5 is mounted on the rotating pin 201, and a protective cover 501 is installed within the fixed housing 1. The damper 5 is located within the protective cover 501. The damper 5 is mounted on the rotating pin 201 to slow the rotation of the bracket 2, preventing the display screen 3 from shaking or impacting due to excessive speed during the rotation process. The protective cover 501 secures the damper 5, protecting it from external interference and protecting the internal structure. The damper 5 has an interference fit with the rotating pin 201 and is embedded in the groove of the protective cover 501. The protective cover 501 and the fixed housing 1 are integrally formed.

[0031] Gear bar 402 is provided with a connecting hole 6, into which a spring 601 is connected. One end of the fixed housing 1 is provided with an arcuate slot 602 and a fixing hole 603. One end of the spring 601 passes through the arcuate slot 602 and is positioned within the fixing hole 603. One end of the spring 601 is fixed within the connecting hole 6 and confined therein. The arcuate slot 602 and the fixing hole 603 define the motion trajectory of the spring 601 and secure its position. After the other end of the spring 601 abuts against the arcuate slot 602, the end of the spring 601 snaps into the fixing hole 603, securing the spring 601. This eliminates the idle travel during the meshing of the first gear 401 and the gear bar 402. The spring 601 applies a tensioning force to the gear bar 402, ensuring that the gear bar 402 and the first gear 401 are always in close contact, thus avoiding idle travel and collision noise during the meshing of the first gear 401 and the gear bar 402. When the drive motor 411 rotates the first gear 401, the spring 601 is in a stretched state, continuously applying a pulling force to the gear bar 402. This pulling force ensures that the gear bar 402 and the first gear 401 are always tightly fitted together, allowing the gear bar 402 to respond immediately when the first gear 401 rotates, eliminating any idle travel between the two. Furthermore, the tight fit prevents the gear bar 402 and the first gear 401 from suddenly contacting and colliding due to excessive clearance, effectively reducing collision noise during the meshing process and improving the smoothness and quietness of the display flipping device.

[0032] Through the coordinated action of the first gear 401 of the driving motor 411, the gear bar 402, the bracket 2 and the spring 601, the viewing and operation needs of people of different body shapes in different positions and sitting postures on the vehicle can be met, thereby improving the convenience and comfort of use.

[0033] The bracket 2 includes a base plate 202, with first protective plates 203 connected to both sides of the base plate 202, and second protective plates 204 connected to both ends of the base plate 202. A first cavity 205 is formed between the base plate 202, the first protective plates 203, and the second protective plates 204. The base of the display screen 3 is disposed within the first cavity 205. The bracket 2 is integrally formed with the base plate 202, the first protective plates 203 on both sides of the base plate 202, and the second protective plates 204 on both ends of the base plate 202, forming the first cavity 205 for mounting the display screen 3. The base of the display screen 3 is secured within the cavity by screws. The first protective plates 203 on the base plate 202 and the second protective plates 204 on one end of the base plate 202 work together to protect the display screen 3 from collisions and prevent dust from contaminating the display screen 3.

[0034] A triangular plate 7 is mounted on one end of the first protective plate 203 and connected to the base plate 202. A pin hole 701 is provided on the triangular plate 7, and one end of the rotating pin 201 is positioned within the pin hole 701. Triangular plate 7 is fixedly attached to the corner of the base plate 202. Triangular plate 7 serves to enhance the structural strength of the bracket 2 and provides a secure mounting fulcrum for the rotating pin 201, ensuring stability during tilting.

[0035] The fixed shell 1 includes a first fixed plate 101, with a second fixed plate 102 connected to its two ends. First flanged plates 103 are provided on both sides of the first fixed plate 101, and second flanged plates 104 are provided on both sides of the second fixed plate 102. The first fixed plate 101 is the bottom plate of the fixed shell 1, and its two ends are connected to the second fixed plate 102. The first fixed plate 101 and the second fixed plate 102 together constitute the overall structure of the fixed shell 1. The first fixed plate 101, the second fixed plate 102, the first flanged plates 103 and the second flanged plates 104 are an integrally molded structure. The first flanged plates 103 on both sides of the first fixed plate 101 are used to increase the bending and twisting resistance of the first fixed plate 101, and the second flanged plates 104 on both sides of the second fixed plate 102 are used to increase the structural strength of the second fixed plate 102.

[0036] A method for assembling a display screen flipping device comprises the following steps:

[0037] Step 101, install the gear shaft 412 in the fixed shell 1, install the first gear 401 on the gear shaft 412, install the drive motor 411 and connect it to the fixed shell 1, and the output shaft of the drive motor 411 is connected to the gear shaft 412; there is a pre-processed bearing mounting hole in the fixed shell 1, press the gear shaft 412, so that the gear shaft 412 passes through the inner ring of the bearing mounting hole, and at the end of the gear shaft 412 extending out of the fixed shell 1, use a spline to connect the first gear 401, and fix the axial position of the first gear 401 with a nut to prevent it from moving on the shaft; fix the drive motor 411 on the outer side of the fixed shell 1 with screws, adjust the position of the drive motor 411 so that the output shaft of the drive motor 411 is coaxial with the gear shaft 412, and connect the drive motor 411 to the gear shaft 412 through a coupling to ensure smooth power transmission.

[0038] Step 102, connect the display screen 3 to the first cavity 205, and connect the gear bar 402 to the bracket 2; connect the base of the display screen 3 to the first cavity 205 of the bracket 2 by screws, ensuring that the display screen 3 does not shake on the bracket 2, and screw holes are provided on the gear bar 402 and one side of the bracket 2. Connect the gear bar 402 and the bracket 2 together by screws, and fit the gear bar 402 to the side of the bracket 2 to ensure that the bracket 2 moves synchronously with the gear bar 402.

[0039] Step 103, install the damper 5 into the protective sleeve plate 501, insert one end of the rotating shaft pin 201 into the damper 5 and fix it on the fixed shell 1, insert the other end of the rotating shaft pin 201 into the pin hole 701, then engage the gear strip 402 with the first gear 401; Apply an appropriate amount of lubricating grease in the groove of the protective sleeve plate 501 on the inner wall of the fixed shell 1, smoothly insert the damper 5 into the groove of the protective sleeve plate 501, use the screw to pass through the mounting hole of the protective sleeve plate 501 and the threaded hole of the damper 5, tighten the screw to fix the damper 5, insert one end of the rotating shaft pin 201 into the center hole of the damper 5, use interference fit to fix the rotating shaft pin 201 and the damper 5, then align the other end of the rotating shaft pin 201 with the pin hole 701 of the triangular plate 7, gently press it in, make the rotating shaft pin 201 pass through the pin hole 701, realize the rotating connection of the support 2 and the fixed shell 1; Then make the support 2 rotate around the rotating shaft pin 201, make the gear strip 402 engage with the first gear 401;

[0040] Step 104, fix one end of the spring 601 in the connecting hole 6, and fix the other end of the spring 601 in the fixed hole 603. One end of the spring 601 is fixed in the connecting hole 6 and is limited in the connecting hole 6, the arc-shaped groove 602 and the fixed hole 603 define the movement track of the spring 601 and fix the position of the spring 601. After the other end of the spring 601 abuts against the arc-shaped groove 602, the end of the spring 601 is clamped into the fixed hole 603, the spring 601 is fixed, the spring 601 can eliminate the idle stroke of the engagement of the first gear 401 and the gear strip 402, the spring 601 exerts tension on the gear strip 402, makes the gear strip 402 always closely engage with the first gear 401, avoids the idle stroke and collision noise in the engagement process of the first gear 401 and the gear strip 402.

[0041] Effects of the embodiment

[0042] The circular first gear 401 meshes with the fan-shaped gear bar 402. The first gear 401 is driven to rotate by the drive motor 411. The first gear 401 meshes with the gear bar 402, causing the gear bar 402 to rotate. The gear bar 402 drives the bracket 2 to flip, and the bracket 2 drives the display screen 3 to flip and rotate around the rotating shaft pin 201, completing the angle adjustment of the display screen 3. The transmission structure is simple and reliable, and can accurately control the flip angle of the display screen 3. The spring 601 applies a tensioning force to the gear bar 402, ensuring that the gear bar 402 and the first gear 401 are always tightly fitted, effectively eliminating the idle travel of the meshing gear bar 402 and the first gear 401, avoiding transmission lag, while reducing collision noise, and improving the smoothness and quietness of the device operation. The damper 5 is mounted on the rotating shaft pin 201 to slow the flipping speed of the bracket 2, preventing the display screen 3 from shaking or impacting due to rapid flipping, protecting the display screen 3 and the internal structure, and extending the service life of the device. Through the coordinated action of the first gear 401 of the driving motor 411, the gear bar 402, the bracket 2 and the spring 601, the viewing and operation needs of people of different body shapes in different positions and sitting postures on the vehicle can be met, thereby improving the convenience and comfort of use.
