Description

Technical Field

[0001] This utility model relates to the field of deflection screen technology, specifically to a double-cylinder telescopic deflection generating device. Background Technology

[0002] With the rapid development of new energy vehicles and the diversification of demands, more and more cars are beginning to be equipped with tiltable central control screens to provide users with a better interactive experience. However, most existing tiltable car central control screens adopt a single-axis rotation structure, which requires a large amount of surrounding space during movement and may have a certain impact on the aesthetics of the interior. Furthermore, the drive and guiding structures of a few dual-cylinder designs are quite complex. In addition, some adjustable-angle in-vehicle displays are not stable and accurate enough during adjustment, and are prone to shaking and shifting, affecting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a dual-cylinder telescopic deflection device with good guidance and stability, simple and compact structure, which can realize screen deflection at multiple angles and directions as well as horizontal screen extension and retraction.

[0004] A dual-cylinder telescopic deflection generating device includes a mounting base, two sets of drive mechanisms, two sets of telescopic mechanisms, and a screen mounting bracket. The two sets of drive mechanisms and the two sets of telescopic mechanisms are mounted on the mounting base. Each telescopic mechanism includes a support rod, a telescopic rod, and a guide tube. The guide tube is mounted on the mounting base, the telescopic rod is movably inserted through the guide tube, and the support rod is rotatably disposed within the telescopic rod. The drive mechanism is connected to one end of the support rod, one end of the telescopic rod is hinged to the screen mounting bracket, and the other end is threadedly connected to the support rod.

[0005] In the above scheme, the mounting base provides stable installation and support for the drive mechanism and the telescopic mechanism, reducing shaking caused by external vibration or internal component movement. The drive mechanism can drive the support rod to rotate within the telescopic rod. Since one end of the telescopic rod is hinged to the screen mounting bracket and the other end is threaded to the support rod, the rotation of the support rod can drive the telescopic rod to move along the length of the support rod, thereby causing the screen mounting bracket to deflect. By controlling the extension length of the two telescopic rods, the direction of deflection and the horizontal telescopic position of the screen mounting bracket can be controlled. The guide tube plays a guiding and limiting role for the telescopic rod, ensuring that the telescopic rod moves strictly according to the predetermined trajectory when moving along the length of the support rod, avoiding deviation or shaking of the telescopic rod, further improving the stability and operating accuracy of the device, making the deflection of the screen mounting bracket more stable and accurate, with a simple overall structure and less space occupation.

[0006] Furthermore, one end of the telescopic rod is provided with a transmission connector, which is threadedly connected to the support rod.

[0007] In the above scheme, when the drive mechanism is started, it will drive the support rod connected to it to rotate. Since the rotation of the support rod is located inside the telescopic rod, and the transmission connector at one end of the telescopic rod is threadedly connected to the support rod, according to the principle of threaded transmission, the rotational motion of the support rod will be converted into the linear motion of the transmission connector and the telescopic rod connected to it. The transmission connector can be customized according to different design requirements and usage scenarios. By changing the size, shape and thread specifications of the transmission connector, the telescopic rod can be adapted to support rods of different specifications, which enhances the versatility and flexibility of the device and expands its application range.

[0008] Furthermore, the transmission connector includes an integrally formed first connecting part and a second connecting part. The first connecting part includes a connecting post, a connecting ring, and a plurality of brackets. One end of the connecting post near the second connecting part is provided with an annular protrusion. One end of the plurality of brackets is connected to the annular protrusion, and the other end is connected to the connecting ring. The connecting ring is sleeved on the outer wall of the telescopic rod.

[0009] In the above scheme, the telescopic rod is sleeved on the connecting column. An annular protrusion is set at one end of the connecting column to limit the telescopic rod and to allow the bracket to be located outside the telescopic rod. The connecting ring is sleeved on the outer wall of the telescopic rod to ensure a stable connection between the transmission connector and the telescopic rod. During the operation of the device, the power can be reliably transmitted from the transmission connector to the telescopic rod, avoiding loosening or falling off during the movement.

[0010] Furthermore, the telescopic rod is provided with several connecting through holes, and the bracket is provided with a protruding structure passing through the connecting through holes, the protruding structure being connected to the connecting column.

[0011] In the above scheme, the connecting through hole on the telescopic rod and the protruding structure on the bracket cooperate with each other, and the protruding structure is connected to the connecting column to form a stable connection system. This connection method makes the connection between the transmission connector and the telescopic rod tighter. During the operation of the device, it can effectively resist various forces such as tension, pressure and torque generated by movement, prevent relative displacement or loosening between the transmission connector and the telescopic rod, greatly improve the connection strength and stability of the entire device, and ensure that the device can work stably for a long time.

[0012] Furthermore, the second connecting part has a rectangular opening in the middle, and the outer wall of the second connecting part away from the first connecting part has several annular grooves. A sealing ring is fitted on the second connecting part and is embedded in the groove.

[0013] In the above solution, the second connecting part is divided into two parts by a rectangular opening, which reduces the difficulty of installing the telescopic rod. During installation, the staff does not need complicated operating skills and tools. They only need to align the two parts of the second connecting part with the support rod and close them, and then put on the sealing ring to complete the installation. The design of the rectangular opening makes the second connecting part have a certain degree of elasticity and adjustability, which can better adapt to the errors and differences between the transmission connecting parts and the support rod. The groove can ensure the stability of the sealing ring.

[0014] Furthermore, a hinge block is connected to the end of the telescopic rod away from the transmission connector, and a hinge seat is provided on the screen mounting bracket, with the hinge block hinged to the hinge seat.

[0015] In the above scheme, the hinge block is hinged to the hinge seat, so that the hinge seat and the hinge block can rotate smoothly along the same axis. When the telescopic rod moves, the screen mounting bracket can move back and forth or tilt left and right, thereby realizing flexible adjustment of the position and angle of the display screen in multiple dimensions.

[0016] Furthermore, the mounting base is provided with two arc-shaped grooves, the guide tube abuts against the arc-shaped grooves, the two sides of the arc-shaped grooves are provided with multiple mounting holes, the guide tube is provided with multiple connecting protrusions, and the connecting protrusions are provided with connecting holes corresponding to the mounting holes.

[0017] In the above scheme, the two arc-shaped grooves on the mounting base provide a specific installation path and position restriction for the guide tube. The guide tube abuts against the arc-shaped grooves, and the shape of the arc-shaped grooves guides the guide tube to be accurately placed in the predetermined position, playing a positioning role. The connecting protrusion has a connecting hole corresponding to the mounting hole. By passing bolts, pins and other connecting parts through the mounting hole and the connecting hole, the guide tube is firmly fixed to the mounting base. This connection method realizes a reliable connection between the guide tube and the mounting base, ensuring that the guide tube will not easily shift or shake during use.

[0018] Furthermore, the drive mechanism includes a connecting base, a drive component, a worm gear, and a worm wheel. The connecting base is connected to the mounting base. The drive component is vertically mounted on the connecting base. The worm gear is connected to the output end of the drive component. The worm wheel meshes with the worm gear. The worm gear and the worm wheel are embedded in the connecting base. One end of the support rod passes through the worm wheel.

[0019] In the above scheme, the driving component is vertically mounted on the connecting base. When the driving component is started, it generates power and transmits it to the output end. Since the worm gear is connected to the output end of the driving component, the rotational power output by the driving component will drive the worm gear to rotate. According to the principle of worm gear transmission, the rotational motion of the worm gear will be converted into the rotational motion of the worm wheel. One end of the support rod passes through the worm wheel. When the worm wheel rotates, it will drive the support rod connected to it to perform corresponding movements. By reasonably designing the transmission ratio of the worm gear and the worm wheel, the rotational speed and angle of the support rod can be precisely controlled, thereby realizing the adjustment of the position and angle of the screen mounting bracket with respect to the support rod.

[0020] Furthermore, the support rod includes a main rod portion, a first connecting rod portion, and a second connecting rod portion connected in sequence. The main rod portion is provided with external threads. The first connecting rod portion passes through the worm gear and has a rectangular cross-section. The second connecting rod portion rotatably passes through the connecting base.

[0021] In the above scheme, the first connecting rod is inserted through the worm gear, and its cross-section is rectangular. The rectangular cross-section design creates a non-circular fit between the first connecting rod and the worm gear, which can effectively prevent relative rotation between the two and avoid the support rod from rotating. When the worm gear rotates under the drive of the worm, it can accurately transmit the rotational motion to the first connecting rod, thereby driving the entire support rod to rotate. The external thread of the main rod cooperates with the transmission connector to realize the movement of the telescopic rod.

[0022] Furthermore, one end of one of the telescopic rods is connected to a hinge rod, one end of which is hinged to the telescopic rod, and the other end is hinged to the screen mounting bracket.

[0023] In the above solution, the hinge rod can increase the degree of freedom of rotation of the screen mounting bracket, so that the display screen is not restricted by the structure when it deflects.

[0024] This utility model discloses a dual-cylinder telescopic deflection generating device with good guidance and stability, simple and compact structure, and the beneficial effects of multi-angle and multi-directional screen deflection and horizontal screen extension. The mounting base provides stable installation and support for the drive mechanism and telescopic mechanism, reducing shaking caused by external vibration or internal component movement. The drive mechanism can drive the support rod to rotate within the telescopic rod. Since one end of the telescopic rod is hinged to the screen mounting bracket and the other end is threaded to the support rod, the rotation of the support rod can drive the telescopic rod to move along the length direction of the support rod, thereby causing the screen mounting bracket to deflect. By controlling the extension length of the two telescopic rods, the direction of screen mounting bracket deflection and the position of horizontal extension are controlled. The guide tube guides and limits the telescopic rod, ensuring that the telescopic rod moves strictly along the predetermined trajectory when moving along the length direction of the support rod, avoiding deviation or shaking of the telescopic rod, further improving the stability and operating accuracy of the device, making the deflection of the screen mounting bracket more stable and accurate. The overall structure is simple and occupies little space. Attached Figure Description

[0032] The present invention provides a more detailed description of a double-cylinder telescopic deflection generating device in conjunction with specific embodiments and accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown in a preferred embodiment, the dual-cylinder telescopic deflection generating device of the present invention includes a mounting base 1, two sets of drive mechanisms 2, two sets of telescopic mechanisms 3, and a screen mounting bracket 4. The two sets of drive mechanisms 2 and the two sets of telescopic mechanisms 3 are mounted on the mounting base 1. The telescopic mechanism 3 includes a support rod 31, a telescopic rod 32, and a guide tube 33. The guide tube 33 is mounted on the mounting base 1. The telescopic rod 32 is movably inserted through the guide tube 33. The support rod 31 is rotatably disposed within the telescopic rod 32. The drive mechanism 2 is connected to one end of the support rod 31. One end of the telescopic rod 32 is hinged to the screen mounting bracket 4, and the other end is threadedly connected to the support rod 31.

[0034] The mounting base 1 provides stable installation and support for the drive mechanism 2 and the telescopic mechanism 3, reducing swaying caused by external vibration or internal component movement. The drive mechanism 2 can drive the support rod 31 to rotate within the telescopic rod 32. Since one end of the telescopic rod 32 is hinged to the screen mounting bracket 4 and the other end is threaded to the support rod 31, the rotation of the support rod 31 can drive the telescopic rod 32 to move along the length direction of the support rod 31, thereby causing the screen mounting bracket 4 to deflect. By controlling the extension length of the two telescopic rods 32, the direction of deflection and the horizontal telescopic position of the screen mounting bracket 4 can be controlled. The guide tube 33 plays a guiding and limiting role for the telescopic rod 32, ensuring that the telescopic rod 32 moves strictly according to the predetermined trajectory when moving along the length direction of the support rod 31, avoiding deviation or swaying of the telescopic rod 32, further improving the stability and operating accuracy of the device, making the deflection of the screen mounting bracket 4 more stable and accurate, with a simple overall structure and less space occupation.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, one end of the telescopic rod 32 is provided with a transmission connector 34, which is threadedly connected to the support rod 31. When the drive mechanism 2 is started, it will drive the support rod 31 connected to it to rotate. Since the support rod 31 is rotatably located inside the telescopic rod 32, and the transmission connector 34 at one end of the telescopic rod 32 is threadedly connected to the support rod 31, according to the principle of threaded transmission, the rotational motion of the support rod 31 will be converted into the linear motion of the transmission connector 34 and the telescopic rod 32 connected to it. The transmission connector 34 can be customized according to different design requirements and usage scenarios. By changing the size, shape, and thread specifications of the transmission connector 34, the telescopic rod 32 can be adapted to support rods 31 of different specifications, which enhances the versatility and flexibility of the device and expands its application range.

[0036] like Figure 3 and Figure 4 As shown, in some embodiments, the transmission connector 34 includes an integrally formed first connecting portion 341 and second connecting portion 342. The first connecting portion 341 includes a connecting post 3411, a connecting ring 3412 and a plurality of brackets 3413. The connecting post 3411 has an annular protrusion 3414 at one end near the second connecting portion 342. One end of the plurality of brackets 3413 is connected to the annular protrusion 3414 and the other end is connected to the connecting ring 3412. The connecting ring 3412 is sleeved on the outer wall of the telescopic rod 32. The telescopic rod 32 is sleeved on the connecting column 3411. An annular protrusion 3414 is provided at one end of the connecting column 3411. On the one hand, it limits the telescopic rod 32, and on the other hand, it allows the bracket 3413 to be located outside the telescopic rod 32. Furthermore, the connecting ring 3412 is sleeved on the outer wall of the telescopic rod 32, thereby ensuring a stable connection between the transmission connector 34 and the telescopic rod 32. During the operation of the device, power can be reliably transmitted from the transmission connector 34 to the telescopic rod 32, preventing loosening or detachment during movement.

[0037] In this embodiment, the telescopic rod 32 is provided with a slot at the position corresponding to the connecting ring 3412. The connecting ring 3412 is locked in the slot to ensure a more stable connection between the transmission connector 34 and the telescopic rod 32.

[0038] like Figure 3 and Figure 4As shown, in some embodiments, the telescopic rod 32 is provided with several connecting through holes, and the bracket 3413 is provided with a protruding structure 3415 passing through the connecting through holes. The protruding structure 3415 is connected to the connecting post 3411. The connecting through holes on the telescopic rod 32 and the protruding structure 3415 on the bracket 3413 cooperate with each other, and the protruding structure 3415 is connected to the connecting post 3411, forming a stable connection system. This connection method makes the connection between the transmission connector 34 and the telescopic rod 32 tighter. During the operation of the device, it can effectively resist various forces such as tension, pressure and torque generated by movement, prevent relative displacement or loosening between the transmission connector 34 and the telescopic rod 32, greatly improve the connection strength and stability of the entire device, and ensure that the device can work stably for a long time.

[0039] like Figure 3 and Figure 4 As shown, in some embodiments, the second connecting part 342 has a rectangular opening 3421 in the middle, and the outer wall of the end of the second connecting part 342 away from the first connecting part 341 has several annular grooves. A sealing ring 3422 is fitted onto the second connecting part 342 and is embedded in the groove. The second connecting part 342 is divided into two parts by the rectangular opening 3421, which reduces the difficulty of installing the telescopic rod 32. During installation, the operator does not need complicated operating skills and tools. They only need to align the two parts of the second connecting part 342 with the support rod 31 and close them, and then put on the sealing ring 3422 to complete the installation. The design of the rectangular opening 3421 gives the second connecting part 342 a certain degree of elasticity and adjustability, which can better adapt to the errors and differences between the transmission connector 34 and the support rod 31. The grooves can ensure the stability of the sealing ring 3422.

[0040] In this embodiment, the transmission connector 34 can be integrally injection molded onto the telescopic rod 32.

[0041] like Figure 2 As shown, in some embodiments, the end of the telescopic rod 32 away from the transmission connector 34 is connected to a hinge block 35, and the screen mounting bracket 4 is provided with a hinge seat 41, with the hinge block 35 hinged to the hinge seat 41. The hinge block 35 and the hinge seat 41 are hinged together, allowing the hinge seat 41 to rotate smoothly along the same axis as the hinge block 35. Thus, when the telescopic rod 32 moves, the screen mounting bracket 4 can move back and forth or tilt left and right, thereby enabling flexible adjustment of the display screen's position and angle in multiple dimensions.

[0042] Specifically, the hinge block 35 and the hinge seat 41 are connected by a connecting pin, so that the hinge block 35 and the hinge seat 41 can rotate about the connecting pin as an axis.

[0043] like Figure 1 and Figure 2As shown, in some embodiments, the mounting base 1 has two arc-shaped grooves 11, the guide tube 33 abuts against the arc-shaped grooves 11, and multiple mounting holes 12 are provided on both sides of the arc-shaped grooves 11. The guide tube 33 has multiple connecting protrusions 331, and the connecting protrusions 331 have connecting holes 3311 at the positions corresponding to the mounting holes 12. The two arc-shaped grooves 11 on the mounting base 1 provide a specific installation path and position restriction for the guide tube 33. The guide tube 33 abuts against the arc-shaped grooves 11, and the shape of the arc-shaped grooves 11 guides the guide tube 33 to be accurately placed in the predetermined position, playing a positioning role. The connecting protrusions 331 have connecting holes 3311 at the positions corresponding to the mounting holes 12. By using bolts, pins, or other connecting parts passing through the mounting holes 12 and connecting holes 3311, the guide tube 33 is firmly fixed to the mounting base 1. This connection method achieves a reliable connection between the guide tube 33 and the mounting base 1, ensuring that the guide tube 33 will not easily shift or shake during use.

[0044] like Figure 3 and Figure 5 As shown, in some embodiments, the drive mechanism 2 includes a connecting base 21, a drive member 22, a worm 23, and a worm wheel 24. The connecting base 21 is connected to the mounting base 1. The drive member 22 is vertically mounted on the connecting base 21. The worm 23 is connected to the output end of the drive member 22. The worm wheel 24 is meshed with the worm 23. The worm 23 and the worm wheel are embedded in the connecting base 21. One end of the support rod 31 passes through the worm wheel 24. The drive member 22 is vertically mounted on the connecting base 21. When the drive member 22 is started, it generates power and transmits it to the output end. Since the worm 23 is connected to the output end of the drive member 22, the rotational power output by the drive member 22 will drive the worm 23 to rotate. According to the transmission principle of the worm 23, the rotational motion of the worm 23 will be converted into the rotational motion of the worm wheel 24.

[0045] One end of the support rod 31 passes through the worm gear 24. When the worm gear 24 rotates, it drives the connected support rod 31 to move accordingly. By rationally designing the transmission ratio of the worm 23 and the worm gear 24, the rotation speed and angle of the support rod 31 can be precisely controlled, thereby achieving the adjustment of the position and angle of the screen mounting bracket 4 connected to the support rod 31. By rationally selecting the parameters of the worm 23 and the worm gear 24, a large reduction ratio can be achieved. This means that the high-speed rotation of the drive component 22 can be converted into the low-speed, high-precision rotation of the support rod 31, thereby precisely controlling the position and angle of the connected components and meeting the precise adjustment requirements in different application scenarios.

[0046] like Figure 3 and Figure 5As shown, in some embodiments, the support rod 31 includes a main rod portion 311, a first connecting rod portion 312, and a second connecting rod portion 313 connected in sequence. The main rod portion 311 has an external thread. The first connecting rod portion 312 passes through the worm gear 24 and has a rectangular cross-section. The second connecting rod portion 313 rotatably passes through the connecting base 21. The first connecting rod portion 312 passes through the worm gear 24 and has a rectangular cross-section. The rectangular cross-section design creates a non-circular fit between the first connecting rod portion 312 and the worm gear 24, which effectively prevents relative rotation between the two and avoids the support rod 31 from rotating. When the worm gear 24 rotates under the drive of the worm 23, it can accurately transmit the rotational motion to the first connecting rod portion 312, thereby driving the entire support rod 31 to rotate. The external thread of the main rod portion 311 cooperates with the transmission connector 34 to transmit power, realizing the movement of the telescopic rod 32.

[0047] like Figure 3 As shown, in some embodiments, one end of one of the telescopic rods 32 is connected to a hinge rod 5. One end of the hinge rod 5 is hinged to the telescopic rod 32, and the other end is hinged to the screen mounting bracket 4. The hinge rod 5 can increase the degree of freedom of rotation of the screen mounting bracket 4, so that the display screen is not structurally restricted when it deflects.

[0048] The working principle and process of this utility model of a double-cylinder telescopic deflection generating device are as follows: When the rotational speed of both driving components 22 is 0, the screen mounting bracket 4 is in the initial state. When the rotational speed of one driving component 22 is greater than that of the other driving component 22, the driving component 22 drives the worm gear 23 to rotate, which in turn drives the worm wheel 24 to rotate and transmits power to the support rod 31. In this way, the rotational speed of one support rod 31 will be greater than that of the other support rod 31. As a result, the horizontal movement speed of one telescopic rod 32 will be greater than that of the other telescopic rod 32. That is to say, the distance that one telescopic rod 32 moves horizontally is greater than the distance that the other telescopic rod 32 moves horizontally, thereby causing the screen mounting bracket 4 to deflect to the left or right. Here, the extreme positions of the screen mounting bracket 4 are all on the same plane.

[0049] In the description of this utility model, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0051] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] Although the description of this utility model has been given in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
