[0036] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0037] Example 1:
[0038] Reference Figure 1 and Figure 2 This embodiment provides a remote image display device, including a main housing 1 and a support assembly 2. The main housing 1 includes a rear shell 11 and a display screen 12, with the display screen 12 disposed on the rear shell 11. The support assembly 2 is disposed on the outside of the rear shell 11, and the rear shell 11 is rotatably connected to the support assembly 2 about a first horizontal direction a, so that the main housing 1 can rotate about the first horizontal direction a. The first horizontal direction a is parallel to the display screen 12, that is, as the main housing 1 rotates about the first horizontal direction a, the display screen 12 is driven to rotate about the first horizontal direction a, thereby realizing the tilt adjustment of the display screen 12 to adapt to different viewing angles and facilitate adjustment.
[0039] Reference Figure 1 and Figure 2 This embodiment provides a far-viewing display device. The support assembly 2 includes a support portion 21 and a first adjustment portion 22. The support portion 21 is vertically disposed on the outside of the rear shell 11, and the first adjustment portion 22 is disposed on the support portion 21 parallel to a first horizontal direction a. The rear shell 11 is rotatably connected to the first adjustment portion 22 about the first horizontal direction a. Specifically, refer to... Figure 2 The first adjustment part 22 is located in the area with the largest curvature on the outer side of the rear shell 11, which makes it easier for the main body shell 1 to rotate as a whole in space, thereby realizing the large-angle tilt of the display screen 12.
[0040] Reference Figure 1 , Figure 2 and Figure 3This embodiment provides a far-viewing display device. A first adjustment unit 22 includes a support shaft 221 disposed on a support unit 21 along a first horizontal direction a, and two bushings 222 sleeved on the support shaft 221. The axes of the bushings 222 and the support shaft 221 are both parallel to the first horizontal direction a. A first positioning strip 223 extending along the first horizontal direction a is provided on the circumferential sidewall of the support shaft 221. Multiple first grooves 224 are sequentially provided circumferentially around the inner side of the bushings 222, and the extending direction of the first grooves 224 is parallel to the first horizontal direction a. The two bushings 222 are symmetrically sleeved on the support shaft 221 relative to its center. The first grooves 224 engage with the first positioning strips 223, and the first positioning strips 223 can be inserted into or extended out of the support shaft 221 radially, allowing the bushings 222 to rotate or stop rotating relative to the support shaft 221. A rear shell 11 is connected to the outer side of the two bushings 222. The specific tilt adjustment process of the display screen 12 is as follows: Force is applied to the rear shell 11, causing the two bushings 222 to rotate around the support shaft 221. During rotation, the first positioning strip 223 radially inserts into the support shaft 221. When rotation stops, the first positioning strip 223 radially extends out of the support shaft 221 and then engages with the first groove 224 to achieve positioning. To facilitate rotation, the cross-sections of the first positioning strip 223 and the first groove 224 are triangular or trapezoidal.
[0041] The first positioning strip 223 can be embedded or extended relative to the support shaft 221. Specifically, an elastic component is provided within the support shaft 221 at a position corresponding to the first positioning strip 223. When the first positioning strip 223 is embedded within the support shaft 221, the elastic component is compressed. The restoring force of the elastic component causes the first positioning strip 223 to extend out of the support shaft 221. The selection and arrangement of the elastic component are existing technologies in the mechanical field and will not be elaborated upon here. The first positioning strip 223 can be segmented, with each segment corresponding to a bushing 222; or the first positioning strip 223 can be a single strip, with one first positioning strip 223 corresponding to two bushings 222 simultaneously.
[0042] Reference Figure 1 and Figure 2 Limiting members 225 are provided at both ends of the support shaft 221. The limiting members 225 are U-shaped and are inserted into the end of the support shaft 221. The limiting members 225 are fixed to the end of the support shaft 221 by bolts. Both ends of the opening of the limiting members 225 abut against one side of the bushing 222 along the first horizontal direction a. In addition, since the two bushings 222 are spaced apart on the rear shell 11, that is, the relative position between the two bushings 222 is fixed, it is only necessary to use the limiting members 225 to limit the two bushings 222 on one side of the support shaft 221, respectively, to prevent the two bushings 222 from displacing relative to the support shaft 221 along the first horizontal direction a.
[0043] Reference Figure 3 , Figure 4 and Figure 5 This embodiment provides a far-image display device. The support assembly 2 further includes a second adjustment part 23, and the support part 21 and the first adjustment part 22 are connected through the second adjustment part 23. The second adjustment part 23 is fixed to the upper end of the support part 21 and can drive the first adjustment part 22 to rotate around a second horizontal direction b, wherein the second horizontal direction b is perpendicular to the first horizontal direction a. The rotation of the first adjustment part 22 around the second horizontal direction b can realize the vertical rotation of the display screen 12 by 180°.
[0044] Reference Figure 3 , Figure 4 and Figure 5 This embodiment provides a far-viewing display device. More specifically, the second adjustment unit 23 includes a first driving unit 231, a vertically arranged worm gear 232, a worm wheel 233 adapted to the worm gear 232, and a driving shaft 234 arranged along the second horizontal direction b and coaxial with the worm wheel 233. The worm wheel 233 is fixedly connected to the driving shaft 234. One end of the driving shaft 234 is connected to the support shaft 221, so that the driving shaft 234 can drive the support shaft 221 to rotate around the second horizontal direction b. The first driving unit 231 is fixed to the upper end of the support unit 21. The upper part of the first driving unit 231 is connected to the worm gear 232. Under the driving action of the first driving unit 231, the worm wheel 233 is driven to rotate, the worm wheel 233 drives the driving shaft 234 to rotate, and then the driving shaft 234 drives the support shaft 221 to rotate around the second horizontal direction b. The first driving unit 231 is a drive motor.
[0045] The flip button 5 is disposed on the base 212. The flip button 5 is electrically connected to the first drive unit 231 to control the operation of the first drive unit 231. The specific control process is referred to the prior art.
[0046] Reference Figure 1 , Figure 2 and Figure 3This embodiment provides a far-viewing display device. The support assembly 2 further includes a telescopic portion 24 connecting the support shaft 221 and the drive shaft 234. The telescopic portion 24 can extend and retract along a second horizontal direction b to adjust the distance between the first adjustment portion 22 and the second adjustment portion 23. In this way, when the main housing 1 rotates around the support shaft 221, interference between the main housing 1 and the support portion 21 can be prevented, thereby satisfying a larger pitch adjustment angle for the main housing 1. More specifically, the telescopic portion 24 is U-shaped, with its open end connected to the support shaft 221. The closed end of the telescopic portion 24, opposite to the open end, is connected to the end of the drive shaft 234. Between the open end and the closed end is a telescopic sleeve 241. The two telescopic sleeves 241 are respectively connected to the support shaft 221. Specifically, one end of the outer sleeve of the telescopic sleeve 241 is fixedly connected to the support shaft 221, and one end of the inner sleeve of the two telescopic sleeves 241 are connected to each other to form the closed end of the telescopic portion 24. The ends of the two telescopic sleeves 241 are respectively connected to the middle of the support shaft 221 and located between the two bushings 222. Without affecting the operation of the bushings 222 and the limiting member 225, the distance between the two telescopic sleeves 241 is set as large as possible, which helps to maintain the stability of the main housing 1.
[0047] When the two telescopic sleeves 241 extend synchronously, the main housing 1 moves away from the support part 21; when the two telescopic sleeves 241 retract synchronously, the main housing 1 moves closer to the support part 21. Once the length of the telescopic sleeve 241 is determined, the inner and outer sleeves can be fixed with bolts. The cross-section of the telescopic sleeve 241 is rectangular to prevent rotation between the inner and outer sleeves. The telescopic sleeve 241 is made of high-strength steel to ensure its supporting function for the main housing 1.
[0048] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This embodiment provides a far-viewing display device. To facilitate adjustment of the height of the main housing 1, the support part 21 includes a lifting member 211 and a base 212 arranged from top to bottom. The lifting member 211 is vertically arranged in the middle of the base 212, and the lifting member 211 can extend and retract in the vertical direction. The extension and retraction of the lifting member 211 raises or lowers the second adjustment part 23, thereby driving the main housing 1 to rise and fall synchronously through the extension and retraction part 24 and the first adjustment part 22. Specifically, the support part 21 also includes a second drive part 213, which can drive the lifting member 211 to extend and retract in the vertical direction.
[0049] The specific process by which the second drive unit 213 drives the lifting member 211 is as follows: The lifting member 211 includes an outer rod 2111 and an inner rod 2112 that are threaded together. A gear ring on the circumferential sidewall of the drive shaft 216 of the second drive unit 213 drives a first gear 218 to rotate. The first gear 218 is fixedly mounted on a driven shaft 217, and its rotation causes the driven shaft 217 to rotate. A gear ring on the upper circumferential sidewall of the driven shaft 217 drives a second gear 219 to rotate. The inner rod 2112 is coaxially and fixedly connected to the second gear 219, meaning the second gear 219 drives the inner rod 2112 to rotate. Consequently, under the action of the threads, the outer rod 2111 rises or falls relative to the inner rod 2112, thus achieving the extension and retraction of the lifting member 211. The inner rod 2112 is mounted to the base 212 via a third sleeve 2113 fitted onto its outer side. For details regarding lifting component 211, please refer to the existing technology for the electric actuator model VT630 manufactured by Foshan Shunde Ruituo Transmission System Co., Ltd.
[0050] Additionally, the lifting component 211 is disposed inside the first sleeve 214 and the second sleeve 215. The lower end of the second sleeve 215 is fixed to the base 212, and the first sleeve 214 and the second sleeve 215 are slidably connected. The upper end of the first sleeve 214 is sealed to form a platform area, which facilitates the connection of the upper end of the outer sleeve 2111 from the inside of the first sleeve 214 to the platform area. On the other hand, the platform area is used to house the second adjustment part 23. For example, the second drive part 213 is fixed to the platform area, and the drive shaft 234 is mounted on the platform area. The first sleeve 214 and the second sleeve 215 cooperate to provide dust protection and protect their internal components.
[0051] The protective cover 235 is used to cover and protect other components of the second adjustment section 23. The lifting button 4 is disposed on the base 212 and is electrically connected to the second drive section 213. It is used to control the extension and retraction of the lifting member 211 driven by the second drive section 213. The specific control process is referred to the prior art.
[0052] It should be noted that the adjustment process of the first adjustment part 22, the second adjustment part 23 and the lifting part 211 on the main unit housing 1 is stable, smooth and easy to operate, which can avoid large vibrations of the main unit housing 1, effectively reduce the vibration of the optical components inside the main unit housing 1, and ensure the stability of the imaging of the far-image display device.
[0053] Reference Figure 1 , Figure 5 and Figure 6This embodiment provides a far-viewing display device, which also includes a mesh fixing cover 3. The shape of the mesh fixing cover 3 is adapted to the rear shell 11, and the mesh fixing cover 3 is fixed to the outside of the rear shell 11. The side of the mesh fixing cover 3 facing away from the rear shell 11 is fixed to the outside of the two bushings 222. The mesh fixing cover 3 is fixed to the rear shell 11 at the intersection, which can realize multi-point fixation between the support component 2 and the main body housing 1, improve the stability of the entire support, and at the same time do not affect the heat dissipation of the main body housing 1, achieving two goals at once.
