[0050] As people's living standards improve, the use of smart display products is increasing. However, many popular mass-market products are constrained by limitations in space, safety, and application scenarios. In particular, mass-market vehicles and health and wellness massage chairs offer a large market and promising prospects. The rapid global development of new energy vehicles, especially autonomous vehicles, will drive even higher demands for leisure and entertainment. Passenger screens, door displays, and rear seat displays are already appearing, and multiple screens are poised to become standard in future vehicles. However, limited space, size restrictions, obstructed vision, and potential safety hazards hinder the adoption of displays, significantly impacting the user experience. Massage chairs, while widely used in both commercial and home settings, are often lacking displays or have smaller, standard screens located on the edge of the armrests. This is primarily due to the fact that adding a display to the front of the massage chair significantly hinders users from getting up and sitting down, effectively becoming a product drawback.

[0051] In response to the above problems, the inventors have designed a display device that can slide and flip the display screen through a sliding flip structure to adjust the posture of the display screen, so that the display device can be adapted to different usage scenarios. The flip structure is driven by a linear transmission mechanism that can change the transmission direction to reduce the size of the drive device in the sliding direction, so that the display device can be adapted to limited spaces and the application range of the display device is improved.

[0052] In view of this, the present invention provides a flexible transmission mechanism for a display device, aiming to solve the problem of how to enable a linear transmission structure to change the transmission direction. Figures 1 to 6 A schematic structural diagram of an embodiment of a flip display device provided by the present invention; Figures 7 to 11 This is a structural schematic diagram of an embodiment of the flexible transmission mechanism provided by the present invention.

[0053] See also Figures 7 to 11The flexible transmission mechanism 200 includes a flexible transmission rod 4, a shaping tube 5 and a driving device 6. The flexible transmission rod 4 can be deformed and bent. The shaping tube 5 is sleeved on the flexible transmission rod 4. The driving device 6 is used to drive the flexible transmission rod 4 to move along its length direction. Inside the shaping tube 5, the flexible transmission rod 4 can adapt to the direction of the shaping tube 5 and deform.

[0054] In the technical solution of the present invention, the shaping tube 5 is installed on the mounting frame 1, and the flexible transmission rod 4 is driven and connected to the sliding rocker arm 21 of the flip display device 100. When the driving device 6 drives the flexible transmission rod 4 forward or backward along the length direction of the shaping tube 5, the flexible transmission rod 4 drives the sliding rocker arm 21 to reciprocate along the length direction of the guide rail beam 11. In this way, by setting the flexible transmission rod 4, the flexible transmission mechanism 200 can be turned to change the transmission direction while also being used to transmit thrust and tension so that the driven structure can reciprocate. At the same time, by setting the shaping tube 5, the flexible transmission rod 4 can be deformed along a preset direction so as to change the transmission direction of the flexible transmission rod 4, thereby reducing the driving stroke of the flexible transmission rod 4 in the length direction of the guide rail beam 11, which is beneficial to reducing the size of the display device, thereby making the display device suitable for limited space and improving the scope of application of the display device.

[0055] Please note that Figure 1 and Figure 2 Generally speaking, linear activity will use a linear transmission mechanism to drive the sliding rocker 21 to slide, but this will increase the size of the display device in the direction of movement of the linear transmission structure, resulting in the display device being too large in size, which does not meet the requirements of thin and narrow products in the design of electronic products. Therefore, in order to reduce the size of the display device, it is necessary to change the transmission direction. The commonly used flexible transmission mechanisms 200 such as chain transmission or belt transmission are only suitable for tensile transmission and have no thrust effect. They cannot be used to push the sliding rocker 21 to slide. Therefore, in the invention, the flexible transmission rod 4 is set so that the flexible transmission mechanism 200 can be used to transmit thrust and tension while being able to turn and change the transmission direction, so that the driven structure can reciprocate. At the same time, the shaping tube 5 is set so that the flexible transmission rod 4 can be deformed along the preset direction to change the transmission direction of the flexible transmission rod 4 and reduce the driving stroke of the flexible transmission rod 4 in the length direction of the guide beam 11, so as to reduce the size of the display device.

[0056] There are many ways to drive the flexible transmission rod 4, for example, it can be driven by a driving cylinder, or it can be driven by other means. Specifically, in this embodiment, please refer to Figure 8 、 Figure 9 and Figure 11 A spiral portion is formed on the outer surface of the flexible transmission rod 4, and the driving device 6 includes a rotatably mounted driving gear, the teeth of the driving gear meshing with the spiral portion for transmission. When the driving gear rotates in the forward direction, the flexible transmission rod 4 is driven by the driving gear to advance along its length direction. When the driving gear rotates in the reverse direction, the flexible transmission rod 4 is driven to retreat along its length direction. In this way, the driving gear and the spiral portion meshing with each other enable the flexible transmission rod 4 to reciprocate along its length direction. Further, the driving device 6 also includes a driving motor 61, and the driving gear drives the main shaft connected to the driving motor 61. In this way, by setting the driving motor 61 to drive the driving gear to rotate, the flexible transmission rod 4 is driven to reciprocate.

[0057] Further, see Figure 7 、 Figure 8 and Figure 11 The flexible transmission mechanism 200 also includes a mounting seat 7, which has two opposite penetration ends and two opposite mounting ends, and a mounting groove 71 is provided on the end surface of one of the mounting ends, and one of the penetration ends is provided with a penetration hole, and the penetration holes are laterally connected to the mounting groove 71, and the shaping tube 5 is correspondingly penetrated in the penetration hole, and the lateral opening 51 of the shaping tube 5 is provided so that the spiral portion can be exposed in the mounting groove 71, and the driving gear is rotatably installed in the mounting groove 71. In this way, by providing the mounting groove 71, the driving motor 61 can drive the driving gear to rotate, and by providing the penetration hole, the shaping tube 5 can be extended into the mounting groove 71, and at the same time, through the lateral opening 51 of the shaping tube 5, the flexible transmission rod 4 in the shaping tube 5 can engage with the driving gear, so that the flexible transmission rod 4 can reciprocate under the drive of the driving motor 61.

[0058] In order to simultaneously drive the two flexible transmission rods 4, in this embodiment, the flexible transmission rod 4, the shaping tube 5 and the through-hole are correspondingly arranged as a transmission group, and two transmission groups are arranged. The spiral parts of the two transmission groups are spaced apart on both sides of the driving gear so that the driving gear can simultaneously drive the two flexible transmission rods 4 to reciprocate.

[0059] In order to enable the flexible transmission rod 4 to transmit thrust and tension, in this embodiment, the flexible transmission rod 4 includes a spiral member 42 of a rod body 41 and an elastic connecting member 43, the spiral member 42 is spirally wound around the rod body 41, and the elastic connecting member 43 is connected between the rod body 41 and the spiral member 42, wherein the spiral portion includes the spiral member 42. In this way, by setting a thinner rod body 41, the rod body 41 can have a certain strength and toughness, so that the flexible transmission rod 4 is easy to bend and deform, and can transmit thrust. The spiral member 42 is set to engage with the driving gear, and the elastic connecting member 43 is set to connect the rod body 41 and the spiral member 42, so as to increase the viscosity between the rod body 41 and the spiral member 42, improve the friction resistance between the rod body 41 and the spiral member 42, and prevent the spiral member 42 and the rod body 41 from sliding against each other.

[0060] Furthermore, the rod body 41 is made of spring steel, which has excellent toughness and rigidity, allows for uniform deformation and rapid recovery. Thus, the use of spring steel allows the flexible transmission rod 4 to bend and deform while also transmitting push and pull forces, ensuring accurate transmission dimensions without causing problems such as breakage, stretching, or bending or stacking. Of course, the rod body 41 may also be made of materials such as rubber.

[0061] In order to facilitate engagement with the driving gear, in this embodiment, refer to Figure 8 and Figure 9 The spiral member 42 includes a spiral steel bar, so that the spiral portion is formed on the outer peripheral side of the rod body 41 to cooperate with the driving gear for transmission. At the same time, by setting the spiral steel bar, it helps to increase the rigidity of the flexible transmission rod 4 without affecting the flexible bending of the flexible transmission rod 4.

[0062] In order to connect the screw member 42 to the rod body 41, in this embodiment, refer to Figure 8 and Figure 9 The elastic connector 43 is made of plastic. Using plastic to wrap the rod body 41 during the injection molding process can increase the outer diameter of the rod body 41 to facilitate mounting the spiral member 42 and increase the rigidity. In other embodiments, the elastic connector 43 can also be made of rubber or the like.

[0063] It should be noted that the above three related technical features: "the material of the rod body 41 includes spring steel", "the spiral member 42 includes spiral steel bars", and "the material of the elastic connecting member 43 includes plastic" can be set one by one or at the same time. Obviously, setting them at the same time will have a better effect.

[0064] In order to strengthen the connection between the rod body 41 and the elastic connecting member 43, in this embodiment, the rod body 41 and the elastic connecting member 43 are integrally injection-molded. In this way, the rod body 41 is wrapped during the injection molding process so that the rod body and the elastic connecting member 43 form a whole, thereby increasing the viscosity between the rod body 41 and the connecting member and avoiding relative sliding between the elastic connecting member 43 and the rod body 41.

[0065] In order to strengthen the connection between the rod body 41 and the elastic connector 43, in this embodiment, a spiral groove is provided on the outer peripheral side of the elastic connector 43 for the spiral 42 to be wound around, so that the spiral 42 can be embedded in the elastic connector 43, thereby increasing the sliding resistance between the spiral 42 and the elastic connector 43, and strengthening the connection between the spiral 42 and the elastic connector 43, so that the spiral 42 maintains a stable position under the action of the driving gear, thereby preventing the spiral 42 and the elastic connector 43 from sliding out of position.

[0066] It should be noted that the above two related technical features: "the rod body 41 and the elastic connecting member 43 are integrally injection-molded" and "a spiral groove is provided on the outer peripheral side of the elastic connecting member 43" can be set one by one or at the same time. Obviously, setting them at the same time will have a better effect.

[0067] In order to strengthen the connection between the rod body 41 and the elastic connecting member 43, in one embodiment, refer to Figure 9 The outer circumferential side surface of the rod body 41 is provided with a plurality of grooves, at least some of which are spaced apart along the circumference of the rod body 41, and / or at least some of which are spaced apart along the axial direction of the rod body 41. In this way, by providing a plurality of grooves, the elastic connector 43 can be embedded in the rod body 41, so as to increase the sliding resistance between the rod body 41 and the elastic member, thereby preventing the rod body 41 and the elastic connector 43 from sliding relative to each other. In addition, since the rod body 41 itself is relatively thin, providing the grooves will reduce the strength of the rod body 41. If an annular groove or a strip groove is directly used, it will have a greater impact on the rod body 41. Therefore, the grooves are spaced apart to minimize the impact of the grooves on the strength of the rod body 41.

[0068] Furthermore, to achieve the above-mentioned objectives, the present invention further provides a display device, comprising the above-mentioned flexible transmission mechanism 200. It should be noted that the structure of the flexible transmission mechanism 200 in the display device can refer to the above-mentioned embodiments of the flexible transmission mechanism 200, and will not be described in detail here. Since the above-mentioned flexible transmission mechanism 200 is used in the display device provided by the present invention, the embodiments of the display device provided by the present invention include all technical solutions of all the above-mentioned embodiments of the flexible transmission mechanism 200, and the technical effects achieved are also identical, and will not be described in detail here.

[0069] Further, see Figures 1 to 4 The display device also includes a flip display device 100, which includes a mounting frame 1, two sliding flip mechanisms 2 and a display body 3. The mounting frame 1 includes two guide rail beams 11 that are opposite and spaced apart in the horizontal direction. The two sliding flip mechanisms 2 are respectively arranged corresponding to the two guide rail beams 11. Each of the sliding flip mechanisms 2 includes two rocker arms. Both rocker arms can rotate relative to the guide rail beam 11 along the axis in the width direction of the guide rail beam 11. At least one rocker arm includes a sliding rocker arm 21. The sliding rocker arm 21 can also move linearly along the length direction of the guide rail beam 11. The display body 3 has two mounting ends that are opposite to each other in its length direction. The two mounting ends respectively correspond to the two guide rail beams 11. It is arranged that each of the mounting ends is provided with two mounting parts, and the two mounting parts are arranged along the width direction of the display body 3. Among the two mounting parts and the two rocker arms, one of the mounting parts is hingedly mounted on the lower end of the corresponding rocker arm, and the other mounting part is fixedly mounted on the lower end of the corresponding rocker arm, wherein the upper ends of the two rocker arms in the same sliding and flipping mechanism 2 move close to each other so that the display body 3 is flipped to the point where the two mounting parts are arranged in the up and down directions, so that the display body 3 is placed in a vertical position, and the upper ends of the two rocker arms in the same sliding and flipping mechanism 2 move away from each other so that the display body 3 is flipped to the point where the two mounting parts are arranged in the horizontal direction, so that the display body 3 is placed in a horizontal position.

[0070] In the technical solution of the present invention, when the user is not using the display device, the sliding swing rod 21 moves in the opposite direction, so that the upper ends of the two swing rods in the same sliding flip mechanism 2 move away from each other, so that the display body 3 is flipped until the two mounting parts are arranged in the horizontal direction, so that the display body 3 is arranged in a horizontal screen, so as to reduce the space occupied by the display body 3. When the user is using the display device, the sliding swing rod 21 moves toward each other, so that the upper ends of the two swing rods in the same sliding flip mechanism 2 move close to each other, so that the display body 3 is flipped until the two mounting parts are arranged in the vertical direction, so that the display body 3 is arranged in a vertical screen for the user to watch. In this way, through the movement of the sliding swing rod 21 in the sliding flip mechanism 2, the two The rocker arms can move closer to or farther away from each other, so that the display body 3 can switch freely between the portrait state or the landscape state, so that the display device can be adjusted according to the user's usage, so as to avoid the display device taking up too much space or being damaged when the display device is not in use. At the same time, by adjusting the position of the sliding rocker arm 21, the distance between the two rocker arms can be adjusted to adjust the flipping angle of the display body 3 so that the display body 3 can adapt to the user's viewing angle. In addition, by setting the two rocker arms, the rotation center of the display body 3 is moved downward to avoid the upper end of the display body 3 extending out of the plane of the mounting frame 1 during the flipping process, thereby preventing the upper end of the display body 3 from touching other components.

[0071] It can be understood that the distance between the two rocker arms can be adjusted by sliding one of the rocker arms, or by sliding both of the rocker arms, etc. The present invention does not limit this. Specifically, in this embodiment, both of the rocker arms include the sliding rocker arm 21, so that both of the rocker arms can move along the length direction of the guide rail beam 11. When the two rocker arms move synchronously in the same direction, the display body 3 can be translated along the length direction of the guide rail beam 11, so that the display body 3 can be closer to or farther away from the user, so that the display body 3 can be in the best viewing position.

[0072] It should be noted that, in theory, the two mounting parts and the two rocker arms can be hingedly connected, but the activity of the two rocker arms is too complicated and cannot ensure that the display body 3 is flipped along the preset direction. Therefore, among the two mounting parts and the two rocker arms, one of the mounting parts is hingedly mounted on the lower end of the corresponding rocker arm, and the other mounting part is fixedly mounted on the lower end of the corresponding rocker arm to ensure that the display body 3 can be flipped along the preset direction.

[0073] It should be understood that, in order to illustrate the directions in the present invention, the length direction of the guide rail beam 11 is taken as the front-to-back direction, the width direction of the guide rail beam 11 is the left-to-right direction, the length direction of the display body 3 is the left-to-right direction, and the width direction of the display body 3 is the front-to-back direction. Of course, the length direction of the guide rail beam 11 can also be other directions, and the present invention is not limited to this.

[0074] In order to make the upper end of the sliding rocker 21 move along the length direction of the guide rail beam 11, in this embodiment, refer to Figure 1 、 Figure 3 and Figure 5 The sliding flipping mechanism 2 also includes a sliding seat 22 arranged corresponding to the sliding rocker 21. The sliding seat 22 moves linearly along the length direction of the guide rail beam 11. The upper end of the sliding rocker 21 is hingedly mounted on the sliding seat 22. In this way, by setting the sliding seat 22, the upper end of the sliding rocker 21 can move along the length direction of the guide rail beam 11. At the same time, the upper end of the sliding rocker 21 is hingedly mounted on the sliding seat 22, so that the upper end of the sliding rocker 21 rotates with the sliding of the sliding seat 22, so that the sliding seat 22 slides.

[0075] Furthermore, in order to drive the sliding seat 22 to slide, in this embodiment, please refer to Figure 1 、 Figure 2 and Figure 5 The inner side surface of the guide rail beam 11 is provided with a slide groove 12 extending along its length direction, and a first slideway 13 extending along its length direction is formed in the guide rail beam 11. A connecting channel is provided between the first slideway 13 and the slide groove 12. The sliding seat 22 includes a sliding portion 221, a traction portion 222, and a connecting portion 223 provided between the sliding portion 221 and the traction portion 222. The connecting portion 223 is provided in the connecting channel so that the sliding portion 221 and the traction portion 222 are respectively located in the slide groove 12 and the first slideway 13. The upper end of the sliding rocker 21 is correspondingly hingedly mounted on the sliding portion 221. Under the action of the traction device, the traction part 222 is slidably installed along the first slide 13, so that the sliding part 221 is slidably installed in the slide groove 12. In this way, by setting the slide groove 12, the sliding part 221 can move along a straight line, and the sliding part 221 and the traction part 222 are connected by setting the connecting part 223, so that the sliding part 221 can slide under the drive of the traction part 222. At the same time, by setting the first slide 13, the traction device can extend into the guide rail beam 11 and connect with the traction part 222, so as to drive the traction part 222 to move along the length direction of the guide rail beam 11.

[0076] Since the sliding portion 221 needs to be hinged to the sliding rocker 21, and the rocker is at the side end of the guide rail beam 11, the sliding portion 221 needs to be arranged on the inner side of the guide rail beam 11 so as to be connected to the sliding rocker 21. However, the sliding portion 221 needs to be arranged on the inner side of the guide rail beam 11, which will cause the upper and lower ends of the sliding portion 221 to be subjected to inconsistent forces, so that the sliding portion 221 is easy to flip toward the inner side of the guide rail beam 11 when sliding. For this reason, in this embodiment, a limiting rib 121 is convexly provided on the inner wall surface of the notch of the slide groove 12, and the sliding portion 221 is stepped to form a limiting step, and the limiting step abuts against the limiting rib 121. In this way, the limiting step and the limiting rib 121 that cooperate with each other can limit the sliding portion 221 in the slide groove 12 to prevent the sliding portion 221 from flipping.

[0077] Theoretically, the two sliding rockers 21 can share the same first slide, but the two sliding seats 22 are prone to interference, resulting in the two sliding seats 22 being unable to completely approach each other. For this reason, in this embodiment, two first slides 13 are provided, and are spaced apart along the width direction of the guide rail beam 11. Correspondingly, two sliding rockers 21 and two sliding seats 22 are provided, and the two sliding seats 22 are spaced apart along the length direction of the guide rail beam 11. The traction parts 222 of each sliding seat 22 are correspondingly arranged in the two first slides 13. In this way, by providing two first slides 13, the two sliding seats 22 are respectively located in different first slides 13, thereby preventing the two sliding seats 22 from interfering with each other.

[0078] In order to facilitate the installation of the sliding seat 22, in this embodiment, please refer to Figure 5 and Figure 6 The guide rail beam 11 includes a lower guide rail 112 and an upper guide rail 111 detachably mounted on the lower guide rail 112. The lower guide rail 112 and the upper guide rail 111 together form the slide groove 12 and the connecting channel. When the sliding seat 22 needs to be installed, the upper guide rail 111 is first removed, and then the sliding seat 22 is installed on the lower guide rail 112, and then the upper guide rail 111 is installed on the lower guide rail 112 to install the sliding seat 22 in the guide rail beam 11. In this way, a detachable structure is adopted to facilitate the loading and unloading of the sliding seat 22.

[0079] In order to prevent the sliding rocker 21 from being separated from the guide rail beam 11, in this embodiment, please refer to Figure 6The lower guide rail 112 is provided with a limiting step surface 1121 along its length direction facing the sliding seat 22 for abutting against the sliding seat 22. In this way, by providing the limiting step surface 1121, the sliding stroke of the sliding seat 22 is limited to prevent the sliding seat 22 from sliding off the guide rail beam 11.

[0080] When the sliding seat 22 at one end of the guide beam 11 is too close to the sliding seat 22 at the other end of the guide beam 11, the span between the two sliding seats 22 is smaller than the span between the two sliding seats 22 when the display body 3 is in landscape mode, resulting in that even if the other sliding seat 22 slides to the end of the other end of the guide beam 11, the display body 3 still cannot be in landscape mode. In view of this, in this embodiment, a limiting rib 14 is provided in the middle part of the guide beam 11 to limit the sliding stroke of the sliding seat 22 to prevent the sliding seat 22 at one end of the guide beam 11 from being too close to the sliding seat 22 at the other end of the guide beam 11, so as to ensure that the distance between the two sliding seats 22 is greater than the distance between the two sliding seats 22 when the display body 3 is in landscape mode.

[0081] Since the force for keeping the display body 3 in the horizontal screen state is provided by the traction device driving the slide, under the condition of constant gravity, the pulling force of the traction device is the largest, and the traction device is a flexible transmission mechanism 200, which has a relatively low strength. Long-term load will reduce the service life of the flexible transmission mechanism 200. Specifically, in this embodiment, please refer to Figure 1 、 Figure 3 and Figure 5 A rotating mounting shaft 23 is connected between the sliding seat 22 and the corresponding sliding rocker 21. A torsion spring 24 is sleeved on the rotating mounting shaft 23. The torsion spring 24 is used to reset the sliding rocker 21 to rotate upward. In this way, the torsion spring 24 offsets a portion of gravity to reduce the load of the flexible transmission mechanism 200, thereby effectively extending the service life of the flexible transmission mechanism 200. In addition, during the flipping process of the display body 3, the torsion spring 24 can act as a buffer, making the flipping speed more uniform and gentle.

[0082] Furthermore, the sliding rocker arm 21 is provided with a receiving groove at one end facing the sliding seat 22, and a fixing hole is opened on the side of the receiving groove. The guide rail beam 11 is provided with an insertion hole on the end face facing the sliding rocker arm 21, and the torsion spring 24 is provided in the receiving groove, and the two ends of the torsion spring 24 are respectively inserted in the insertion hole and the fixing hole. In this way, by providing the fixing hole and the insertion hole, the two ends of the torsion spring 24 can be respectively installed on the sliding seat 22 and the sliding rocker arm 21, so that it will deform when the sliding rocker arm 21 rotates, thereby offsetting part of the gravity of the display body 3. At the same time, by providing the receiving groove, the torsion spring 24 can be hidden in the sliding rocker arm 21, which can not only protect the torsion spring 24, but also improve the appearance of the flip display device 100.

[0083] In order to improve the appearance of the flip display device 100, specifically, in one embodiment, refer to Figure 1 、 Figure 3 and Figure 4 The inner side of the guide rail beam 11 is provided with a wiring tube 15 extending along its length. Thus, by providing the wiring tube 15, the wiring harness is installed on the inner side of the guide rail beam 11, which not only facilitates the wiring of the wiring harness, but also shields the wiring harness, preventing the wiring harness from being directly exposed outside the mounting frame 1, thereby helping to improve the appearance of the flip display device 100. In another embodiment, please refer to Figure 3 The sliding rocker 21 is provided with a wiring groove 211. By providing the wiring groove 211, the wiring harness is hidden within the sliding rocker 21, which not only facilitates the wiring of the wiring harness but also shields the wiring harness from being directly exposed outside the sliding rocker 21, thereby helping to enhance the appearance of the flip display device 100. It should be noted that the two related technical features mentioned above, namely, "a wiring tube 15 extending along the length of the guide rail beam 11 is provided on the inner side thereof" and "a wiring groove 211 is formed on the sliding rocker 21", can be provided either alone or simultaneously. Obviously, providing both provides a better effect.
