Detailed Description

Embodiments of the present utility model will be described in detail below, with reference to the accompanying drawings, which are exemplary, and a pitch mechanism 100 for an in-vehicle display screen 200 according to a first aspect of the present utility model will be described below with reference to fig. 1 to 10. In the following description of the present application, the pitching mechanism 100 is described by taking as an example a pitching state for adjusting the in-vehicle display screen 200. But is not limited thereto.

As shown in fig. 1 and 2, a tilting mechanism 100 for an in-vehicle display screen 200 according to an embodiment of the first aspect of the present utility model includes a base 1, at least one hinge assembly 2, a tilting bracket 3, and a driving assembly 4.

Specifically, the hinge assembly 2 is provided on the base 1. Thus, the base 1 can support the hinge assembly 2, and the stability of the hinge assembly 2 in use can be improved. The flip bracket 3 is pivotally connected to the hinge assembly 2, and the flip bracket 3 is rotatable relative to the base 1 about a first direction (e.g., the direction indicated by arrow a in fig. 2). That is, the flip bracket 3 can be in a rotatable state with respect to the base 1 by the hinge assembly 2. Moreover, the tilting bracket 3 and the base 1 are integrally connected by the hinge assembly 2, which is advantageous for installation and use of the pitching mechanism 100.

The in-vehicle display screen 200 is adapted to be provided at one end of the roll-over stand 3. For example, in the example of fig. 2, the above-described one end of the flip bracket 3 is the left end of the flip bracket 3. When the turnover bracket 3 rotates around the first direction, the one end of the turnover bracket 3 can drive the vehicle-mounted display screen 200 to synchronously rotate. Thereby, the rotation angle of the in-vehicle display screen 200 can be adjusted by adjusting the rotation angle of the one end of the tilting bracket 3.

The driving component 4 is arranged on the base 1, the driving component 4 is connected with the other end of the overturning bracket 3, and when the driving component 4 works, the driving component 4 drives the other end of the overturning bracket 3 to rotate around the first direction so as to be suitable for adjusting the pitching angle of the vehicle-mounted display screen 200. For example, in the example of fig. 2, the other end of the flip bracket 3 is the right end of the flip bracket 3, and the driving assembly 4 is located below the flip bracket 3 and connected to the right end of the flip bracket 3. So set up, can control the pitch angle of on-vehicle display screen 200 through the operating condition of control drive assembly 4, from this, the customer can adjust the turned angle of on-vehicle display screen 200 according to the in-service use demand to satisfy customer's vision demand, promote customer's use experience. In addition, the driving component 4 can provide driving force for the overturning bracket 3 to rotate around the first direction, which is beneficial to smooth rotation of the overturning bracket 3 and saves manpower.

According to the pitching mechanism 100 for the vehicle-mounted display screen 200, the pitching mechanism 100 is simple in structure and convenient to use. When the pitching mechanism 100 is applied to the vehicle-mounted display screen 200, the vehicle-mounted display screen 200 can rotate around the first direction through the combined action of the overturning bracket 3, the hinge assembly 2 and the driving assembly 4, the pitching angle of the vehicle-mounted display screen 200 can be adjusted according to the use requirements of different clients, the universality of the vehicle-mounted display screen 200 is improved, and the use experience of the clients is improved.

According to some embodiments of the present utility model, referring to fig. 3 and 4, the hinge assembly 2 includes a first hinge bracket 21 and a second hinge bracket 22, the first hinge bracket 21 being provided on the base 1. Thereby, the base 1 can be used to support and fix the first hinge bracket 21, so that the stability of the first hinge bracket 21 can be improved. The second hinge bracket 22 is pivotally connected to the first hinge bracket 21 through a rotation shaft 23, the first direction is the central axis direction of the rotation shaft 23, and the flip bracket 3 is connected to the second hinge bracket 22. For example, in the example of fig. 3 and 4, the free end of the rotation shaft 23 may pass through the first hinge bracket 21 and the second hinge bracket 22 in sequence. Thereby, the first hinge bracket 21, the tilting bracket 3, and the second hinge bracket 22 can be simultaneously rotated about the central axis of the rotation shaft 23, so that the tilt angle of the in-vehicle display screen 200 can be adjusted by the rotation angle of the second hinge bracket 22. Further, the position and the direction of rotation of the second hinge bracket 22 can be defined by the position and the direction of extension of the rotation shaft 23.

Further, the first hinge bracket 21 includes a first hinge plate 211 and a second hinge plate 212 connected to each other, the first hinge plate 211 being fixedly connected to the base 1, the second hinge plate 212 extending in the up-down direction. For example, in the example of fig. 3 and 4, the first hinge plate 211 extends in the left-right direction, the second hinge plate 212 extends in the up-down direction, and the first hinge plate 211 and the second hinge plate 212 are perpendicular to each other. So arranged, on the one hand, the contact area between the first hinge plate 211 and the base 1 is increased, and the connection between the first hinge plate 211 and the base 1 is more fastened; on the other hand, the structural strength of the first hinge bracket 21 is improved, facilitating long-term use of the first hinge bracket 21.

Referring to fig. 3 and 4, the second hinge bracket 22 includes a third hinge plate 221 and a fourth hinge plate 222 connected to each other, the third hinge plate 221 extending in an up-down direction, the third hinge plate 221 being located at one side of the thickness direction (e.g., the direction indicated by arrow C in fig. 3) of the second hinge plate 212, and the rotation shaft 23 passing through the third hinge plate 221 and the second hinge plate 212. For example, in the example of fig. 3, the third hinge plate 221 is opposite to the second hinge plate 212, and the third hinge plate 221 is located at a side of the second hinge plate 212 distant from the first hinge plate 211 in the thickness direction. Therefore, the first hinge bracket 21 and the second hinge bracket 22 are reasonably arranged, interference between the second hinge bracket 22 and the first hinge bracket 21 in the rotation process is reduced, and rotation of the third hinge plate 221 is facilitated. The fourth hinge plate 222 is fixedly connected with the turnover bracket 3. For example, in the example of fig. 3 and 4, the fourth hinge plate 222 is fixed to the flip bracket 3 at the upper end of the third hinge plate 221, and thus, the flip bracket 3 is spaced from the rotation shaft 23 and the third hinge plate 221, and interference of the rotation shaft 23 and the third hinge plate 221 to the rotation of the flip bracket 3 is reduced, so that the flip bracket 3 can be smoothly rotated.

According to some embodiments of the present utility model, referring to fig. 3 and 4, a first coupling hole 2121 is formed on the second hinge plate 212, a second coupling hole 2211 is formed on the third hinge plate 221, the rotation shaft 23 includes a first shaft section 231 and a second shaft section 232 connected to each other in an axial direction of the rotation shaft 23, a shape of the first shaft section 231 is adapted to a shape of the first coupling hole 2121, and a shape of the second shaft section 232 is adapted to a shape of the second coupling hole 2211. For example, in the example of fig. 3, a portion of the first shaft segment 231 is positioned in the first mating hole 2121 and connected to the second hinge plate 212, and a portion of the second shaft segment 232 is positioned in the second mating hole 2211 and connected to the third hinge plate 221. Thereby, the assembly of the rotation shaft 23 with the third hinge plate 221 and the second hinge plate 212 is facilitated. Wherein the first mating hole 2121 is a circular hole, thereby facilitating rotation of the first shaft segment 231 within the first mating hole 2121 and thus facilitating rotation of the second hinge bracket 22. The second mating hole 2211 is a non-circular hole, so that the second shaft section 232 and the third hinge plate 221 can rotate synchronously, and further the second hinge bracket 22 is beneficial to driving the turning bracket 3 and the vehicle-mounted display screen 200 to rotate.

According to some alternative embodiments of the present utility model, referring to fig. 4, the end of the second shaft section 232 remote from the first shaft section 231 is provided with a limiting piece 233, and the limiting piece 233 is located at the side of the third hinge plate 221 remote from the second hinge plate 212. Therefore, the limiting piece 233 can limit the movement of the second shaft section 232 in the central axis direction of the rotating shaft 23, so that the falling probability of the second shaft section 232 from the second matching hole 2211 is reduced, and the connection stability of the rotating shaft 23 and the third hinge plate 221 is improved, thereby being beneficial to long-term use of the hinge assembly 2. The free end of the first shaft section 231 passes through the third hinge plate 221 and the second hinge plate 212 and is threadedly engaged with the nut 235. Therefore, the free end of the first shaft section 231 can be fixed by the nut 235, and the first shaft section 231 is prevented from falling from the first matching hole 2121, so that the connection stability of the first shaft section 231 and the second hinge plate 212 is improved, and the long-term use stability of the first hinge bracket 21 and the second hinge bracket 22 is further improved. Of course, as shown in fig. 2, the limiting piece 233 may also be disposed on a side of the second hinge plate 212 away from the third hinge plate 221, and the free end of the first shaft segment 231 sequentially passes through the second hinge plate 212 and the third hinge plate 221 and is in threaded engagement with the nut 235.

For example, in the example of fig. 4, the spacing tab 233 may be a circular tab, with the cross-sectional area of the spacing tab 233 being greater than the cross-sectional area of the second shaft section 232. Thereby, the movement of the second shaft section 232 in the central axis direction of the rotating shaft 23 can be effectively restricted, and the processing of the limit pieces 233 is facilitated. But is not limited thereto.

According to some embodiments of the present utility model, the rotating shaft 23 is sleeved with a plurality of friction plates 234, and the friction plates 234 are abutted along the axial direction of the rotating shaft 23. In the description of the present utility model, "plurality" means two or more. For example, in the example of fig. 4, eight friction plates 234 are provided on the rotating shaft 23. Therefore, when the rotating shaft 23 rotates around the first direction, the rotation resistance to the rotating shaft 23 is formed by the stopping between the friction plates 234, so that the shaking in the rotating process of the rotating shaft 23 is reduced, the rotating stability of the overturning bracket 3 and the vehicle-mounted display screen 200 is improved, the damage to the vehicle-mounted display screen 200 due to shaking in the rotating process of the overturning bracket 3 is reduced, and the service life of the vehicle-mounted display screen 200 is prolonged. In addition, the second hinge bracket 22 has stable holding force after stopping rotating, so that shaking of the vehicle-mounted display screen 200 after stopping rotating is reduced, and accuracy of adjusting the rotating angle of the vehicle-mounted display screen 200 is improved. It should be noted that the magnitude of the rotation resistance can be adjusted by the number of friction plates 234 and the matching relationship between the nut 235 and the first shaft section 231. Therefore, the number of the friction plates 234 used may be specifically set according to the actual situation to better satisfy the actual application.

Alternatively, the plurality of friction plates 234 may each be a metal piece, each be a plastic piece, or a combination of a partial metal piece and a partial plastic piece. Thereby, the friction plate 234 is advantageously used for a long time, the durability of the friction plate 234 is improved, and the noise during the rotation of the tilting bracket 3 is less. But is not limited thereto.

According to some alternative embodiments of the present utility model, referring to fig. 4, a plurality of spacers 236 are sleeved on the rotating shaft 23, and the plurality of spacers 236 are disposed between the limiting plate 233 and the friction plate 234. Thus, the rotation resistance to the rotation shaft 23 is further increased by the combined action of the plurality of gaskets 236 and the plurality of friction plates 234, so that the rotation stability of the second hinge bracket 22 is further improved, and the rotation stability of the roll-over bracket 3 and the in-vehicle display screen 200 is further improved. In addition, the plurality of shims 236 also makes the connection between the first hinge bracket 21 and the rotation shaft 23 more stable. It should be noted that the number of shims 236 may be used to adjust the rotational resistance to better satisfy the practical application.

According to other embodiments of the present utility model, a spring (not shown) may be sleeved on the rotating shaft 23. Thus, resistance to the rotation process of the rotation shaft 23 and the second hinge bracket 22 can be provided by the elastic force of the spring, so that the rotation of the roll-over bracket 3 and the in-vehicle display screen 200 is more stable, and shaking after the rotation of the roll-over bracket 3 and the in-vehicle display screen 200 is stopped can be reduced. But is not limited thereto.

Further alternatively, the hinge assemblies 2 are plural, and the plural hinge assemblies 2 are arranged at intervals along the first direction. For example, in the example of fig. 2, the hinge assemblies 2 are two, the two hinge assemblies 2 are spaced apart along the first direction, and the two hinge assemblies 2 are respectively adjacent to the edges of the base 1 along the first direction, and at this time, two sides of the flip bracket 3 along the first direction may be respectively connected to the base 1 through the hinge assemblies 2. So set up, the connection of upset support 3 and base 1 is more firm to upset support 3 is whole be difficult for rocking more in the rotation in-process, has further improved the stability that upset support 3 used for a long time. It should be noted that, the number and arrangement of the hinge assemblies 2 may be selected according to the size of the vehicle-mounted display screen 200, so as to better satisfy practical applications.

According to some embodiments of the present utility model, the drive assembly 4 comprises a drive 41 and at least one link 42. The driving device 41 is provided on the base 1, and one end of the link 42 is pivotally connected to the other end of the flip bracket 3, and the other end of the link 42 is pivotally connected to the driving device 41 and movable in a second direction (for example, a direction indicated by an arrow B in fig. 2) perpendicular to the first direction. Thereby, the driving device 41 can drive the other end of the connecting rod 42 to move along the second direction, and simultaneously drive the one end of the connecting rod 42 to push the other end of the turning support 3 to rotate, so that the one end of the turning support 3 and the vehicle-mounted display screen 200 rotate around the first direction. Moreover, the driving assembly 4 is simple in structure and convenient to operate, and is beneficial to adjusting the pitching angle of the vehicle-mounted display screen 200.

For example, in the examples of fig. 5 and 6, the operation of the drive assembly 4 is generally as follows: when the driving device 41 drives the left end of the connecting rod 42 to move from left to right (i.e. along the second direction), the right end of the connecting rod 42 can push the right end of the turning bracket 3 to rotate around the first direction (i.e. rotate along the counterclockwise direction), and at the same time, the left end of the turning bracket 3 drives the vehicle-mounted display screen 200 to rotate along the counterclockwise direction. When the left end of the link 42 moves to the right side of the base 1 in the second direction, the roll-over stand 3 and the in-vehicle display screen 200 stop rotating. When the driving device 41 drives the left end of the connecting rod 42 to move from right to left, the right end of the connecting rod 42 pulls the right end of the turning bracket 3 to rotate in the clockwise direction, and meanwhile, the right end of the turning bracket 3 drives the left end of the turning bracket 3 and the vehicle-mounted display screen 200 to rotate in the clockwise direction. When the left end of the link 42 moves to the left side of the base 1 in the second direction, the roll-over stand 3 and the in-vehicle display screen 200 are rotated back to the original state.

Alternatively, referring to fig. 5 to 7, the driving device 41 includes a driver 411, a screw 412 and a moving member 413, the screw 412 extends in the second direction, the screw 412 is connected to the driver 411 and is driven by the driver 411 to rotate around the central axis of the screw 412, the moving member 413 is sleeved outside the screw 412 and is screw-engaged with the screw 412, the moving member 413 is movable relative to the screw 412 in the axial direction of the screw 412, and the other end of the link 42 is pivotally connected to the moving member 413. Therefore, when the driver 411 works, the driver 411 can drive the screw 412 to rotate, the screw 412 can drive the moving member 413 sleeved on the screw 412 to move, and the connecting rod 42 plays a limiting role on the moving member 413 because the other end of the connecting rod 42 is connected with the moving member 413, so that the moving member 413 can do linear motion along the extending direction of the screw 412, and the moving member 413 can push the overturning bracket 3 to rotate around the first direction through the connecting rod 42. In addition, the driving device 41 has a simple structure and is convenient to operate, and the assembly and the use of the driving device 41 are facilitated.

Alternatively, the driving device 41 may be a cylinder (not shown) provided on the base 1, the piston rod of which is connected to the other end of the push rod. So configured, the cylinder can drive the other end of the link 42 to move in the second direction, so that the link 42 can drive the roll-over stand 3 and the in-vehicle display screen 200 to rotate around the first direction. In addition, the structure of the driving device 41 can be made simpler, and the space occupied by the driving device 41 on the base 1 can be saved, so that the structure of the pitching mechanism 100 is made simpler, and the assembly and the use of the pitching mechanism 100 are facilitated. But is not limited thereto.
