Description

Technical Field

[0001] This invention relates to the field of display device technology, and in particular to a flip display device and a display device. Background Technology

[0002] As people's living standards improve, the application of intelligent display products is increasing. However, in many popular mass-market products, limitations such as spatial structure, safety performance, and application scenarios restrict the application of display products. This is especially true for mass-market consumer display devices and health and wellness products like massage chairs, which have a large market size and broad prospects. New energy display devices are developing rapidly globally, particularly in autonomous driving displays, which will place higher demands on leisure and entertainment. Features such as passenger-side screens, door displays, and rear seat displays have already emerged, and multiple screens in a vehicle will inevitably become standard in the future. However, limitations in vehicle space, size restrictions, obstructed views, and potential safety hazards restrict the application of displays, severely impacting the user experience. Massage chairs have many applications in both commercial and home settings, but most do not feature displays or have small, ordinary screens on the edge armrests. The main reason is that adding a display screen to the front of the massage chair would significantly hinder the user's ability to sit and stand, becoming a product drawback. Summary of the Invention

[0003] To address the aforementioned problems, the inventors designed a display device that allows the screen to be slidably flipped via a sliding flip structure, adjusting the screen's orientation to suit different usage scenarios. A linear transmission mechanism capable of changing the transmission direction drives the flip structure, reducing the size of the driving device in the sliding direction and enabling the display device to be used in limited spaces, thus expanding its application range. Therefore, designing a sliding flip structure that allows the screen to adopt different orientations is a problem that urgently needs to be solved.

[0004] The main objective of this invention is to provide a flip display device and a display apparatus, which aims to solve the problem of how to design a sliding flip structure so that the display screen can have different postures.

[0005] To achieve the above objectives, the present invention provides a flip display device, comprising:

[0006] The mounting bracket includes two horizontally opposed and spaced-apart guide beams;

[0007] Two sliding tilting mechanisms are respectively arranged corresponding to the two guide rail beams. Each sliding tilting mechanism includes two swing arms, both of which are capable of rotating relative to the guide rail beam along the axis located in the width direction. At least one swing arm includes a sliding swing arm, which is also capable of linear movement along the length direction of the guide rail beam; and...

[0008] The display body has two mounting ends opposite each other in its length direction. The two mounting ends are respectively set for the two guide rail beams. Each mounting end is provided with two mounting parts. The two mounting parts are arranged along the width direction of the display body. Among the two mounting parts and the two swing arms, one of the mounting parts is hinged to the lower end of the corresponding swing arm, and the other mounting part is fixedly installed to the lower end of the corresponding swing arm.

[0009] In this mechanism, the upper ends of the two swing arms in the same sliding flipping mechanism move closer to each other, so that the display body flips to the point where the two mounting parts are arranged vertically, so that the display body is placed in a vertical screen position.

[0010] The upper ends of the two swing arms in the same sliding flipping mechanism move away from each other, so that the display body flips so that the two mounting parts are arranged in the horizontal direction, so that the display body is placed in a horizontal position.

[0011] Optionally, the sliding flipping mechanism further includes a sliding seat corresponding to the sliding rocker arm, the sliding seat moving linearly along the length direction of the guide beam;

[0012] The upper end of the sliding rocker arm is hinged to the sliding base.

[0013] Optionally, the inner side of the guide beam is provided with a groove extending along its length, a first slide rail extending along its length is formed in the guide beam, and a connecting channel is provided between the first slide rail and the groove.

[0014] The sliding seat includes a sliding part, a traction part, and a connecting part disposed between the sliding part and the traction part. The connecting part is disposed in the connecting channel so that the sliding part and the traction part are respectively located in the slide groove and the first slide rail. The upper end of the sliding rocker arm is correspondingly hinged to the sliding part.

[0015] Under the action of the traction device, the traction part is slidably installed along the first slide rail, so that the sliding part is slidably installed in the slide groove.

[0016] Optionally, a limiting rib is provided on the inner wall surface of the groove opening;

[0017] The sliding part is stepped to form a limiting step, and the limiting step abuts against the limiting rib.

[0018] Optionally, two first slide rails are provided, and they are spaced apart along the width direction of the guide beam;

[0019] Correspondingly, two sliding rods and two sliding seats are provided. The two sliding seats are spaced apart along the length of the guide beam, and the traction part of each sliding seat is respectively located in the two first slide rails.

[0020] Optionally, the guide beam includes a lower guide rail and an upper guide rail detachably mounted on the lower guide rail, the lower guide rail and the upper guide rail together forming the slide groove and the communicating channel.

[0021] Optionally, a rotating mounting shaft is connected between the sliding seat and the corresponding sliding rocker arm, and a torsion spring is sleeved on the rotating mounting shaft to reset the sliding rocker arm to rotate upward.

[0022] Optionally, the sliding rocker arm has a receiving groove at one end facing the sliding seat, and a fixing hole is provided on the side of the receiving groove;

[0023] The guide rail beam has an insertion hole on its end face facing the sliding rocker arm;

[0024] The torsion spring is disposed in the receiving groove, and its two ends are respectively inserted into the insertion hole and the fixing hole.

[0025] Optionally, the inner side of the guide beam is provided with a cable routing conduit extending along its length; and / or,

[0026] The sliding rocker arm has a cable routing groove.

[0027] In addition, the present invention also provides a display device, the display device including the above-described flip display device.

[0028] In the technical solution of this invention, when the user is not using the display device, the sliding lever moves in the opposite direction, causing the upper ends of the two levers in the same sliding flip mechanism to move away from each other, so that the display body flips so that the two mounting parts are arranged horizontally, making the display body horizontally positioned to reduce the space occupied by the display body. When the user uses the display device, the sliding levers move towards each other, causing the upper ends of the two levers in the same sliding flip mechanism to move closer to each other, so that the display body flips so that the two mounting parts are arranged vertically, making the display body vertically positioned for the user to view. Thus, through the movement of the sliding levers in the sliding flip mechanism, the two mounting parts are moved away from each other, so that the display body flips so that the two mounting parts are arranged vertically, making the display body vertically positioned for the user to view. The swing arms can move closer or further apart, allowing the display unit to freely switch between portrait and landscape modes. This enables the display device to be adjusted according to user needs, preventing it from occupying too much space or being damaged when not in use. Furthermore, adjusting the position of the swing arms allows for adjustment of the distance between them, thus adjusting the rotation angle of the display unit to suit the user's viewing angle. Additionally, the two swing arms lower the center of rotation of the display unit, preventing the upper part of the display unit from extending beyond the plane of the mounting bracket during rotation and thus preventing it from touching other components.

[0048] As people's living standards improve, the application of intelligent display products is increasing. However, in many popular mass-market products, limitations such as spatial structure, safety performance, and application scenarios restrict the application of display products. This is especially true for mass-market consumer display devices and health and wellness products like massage chairs, which have a large market size and broad prospects. New energy display devices are developing rapidly globally, particularly in autonomous driving displays, which will place higher demands on leisure and entertainment. Features such as passenger-side screens, door displays, and rear seat displays have already emerged, and multiple screens in a vehicle will inevitably become standard in the future. However, limitations in vehicle space, size restrictions, obstructed views, and potential safety hazards restrict the application of displays, severely impacting the user experience. Massage chairs have many applications in both commercial and home settings, but most do not feature displays or have small, ordinary screens on the edge armrests. The main reason is that adding a display screen to the front of the massage chair would significantly hinder the user's ability to sit and stand, becoming a product drawback. To address the aforementioned problems, the inventors have designed a display device that can slide and flip the display screen via a sliding flip structure to adjust the screen's orientation, making the display device suitable for different usage scenarios. Furthermore, a linear transmission mechanism capable of changing the transmission direction drives the flip structure, thereby reducing the size of the driving device in the sliding direction and enabling the display device to be used in limited spaces, thus expanding its application range.

[0049] In view of this, the present invention provides a flip display device for a display device, aiming to solve how to design a sliding flip structure so that the display screen can have different postures. Wherein, Figures 1 to 6 This is a schematic diagram of a structure of an embodiment of the flip display device provided by the present invention; Figures 7 to 11 This is a schematic diagram of an embodiment of the flexible transmission mechanism provided by the present invention.

[0050] Please see Figures 1 to 4The flip display device 100 includes a mounting frame 1, two sliding flip mechanisms 2, and a display body 3. The mounting frame 1 includes two horizontally opposed and spaced guide rail beams 11. The two sliding flip mechanisms 2 are respectively arranged corresponding to the two guide rail beams 11. Each sliding flip mechanism 2 includes two swing arms, and both swing arms can rotate relative to the guide rail beam 11 along the axis located in the width direction of the guide rail beam 11. At least one swing arm includes a sliding swing arm 21, and the sliding swing arm 21 can also move linearly along the length direction of the guide rail beam 11. The display body 3 has two mounting ends opposite each other in its length direction, and the two mounting ends are respectively arranged corresponding to the two guide rail beams 11. The display body 3 is provided with two mounting parts, which are arranged along the width direction of the display body 3. One of the mounting parts is hinged to the lower end of the corresponding swing arm, and the other mounting part is fixedly installed to the lower end of the corresponding swing arm. The upper ends of the two swing arms in the same sliding flip mechanism 2 move closer to each other, so that the display body 3 is flipped so that the two mounting parts are arranged vertically, making the display body 3 vertically positioned. The upper ends of the two swing arms in the same sliding flip mechanism 2 move further apart, so that the display body 3 is flipped so that the two mounting parts are arranged horizontally, making the display body 3 horizontally positioned.

[0051] In the technical solution of this invention, when the user is not using the display device, the sliding lever 21 moves in the opposite direction, causing the upper ends of the two levers in the same sliding flip mechanism 2 to move away from each other, so that the display body 3 is flipped so that the two mounting parts are arranged horizontally, making the display body 3 horizontally positioned to reduce the space occupied by the display body 3. When the user uses the display device, the sliding lever 21 moves towards each other, causing the upper ends of the two levers in the same sliding flip mechanism 2 to move closer to each other, so that the display body 3 is flipped so that the two mounting parts are arranged vertically, making the display body 3 vertically positioned for the user to view. Thus, through the movement of the sliding lever 21 in the sliding flip mechanism 2, the two... The swing arms can move closer to or further apart from each other, allowing the display body 3 to freely switch between portrait and landscape modes. This enables the display device to be adjusted according to the user's usage, preventing it from occupying too much space or being damaged when not in use. Furthermore, by adjusting the position of the sliding swing arm 21, the distance between the two swing arms can be adjusted to change the rotation angle of the display body 3, adapting it to the user's viewing angle. Additionally, the two swing arms lower the rotation center of the display body 3, preventing its upper end from extending beyond the plane of the mounting bracket 1 during rotation and thus preventing it from touching other components.

[0052] It is understood that the distance between the two swing arms can be adjusted by sliding one of the swing arms or by sliding both of the swing arms, etc. The present invention does not limit this. Specifically, in this embodiment, both swing arms include the sliding swing arm 21 so that both swing arms can move along the length direction of the guide beam 11. When the two swing arms move synchronously in the same direction, the display body 3 can be translated along the length direction of the guide beam 11 so that the display body 3 moves closer to or further away from the user, thereby allowing the display body 3 to be in the optimal viewing position.

[0053] It should be noted that, theoretically, the two mounting parts and the two swing arms can be hinged together. However, the movement of the two swing arms is too complex at this time, and it cannot guarantee that the display body 3 can flip along the preset direction. Therefore, of the two mounting parts and the two swing arms, one of the mounting parts is hinged to the lower end of the corresponding swing arm, and the other mounting part is fixedly installed to the lower end of the corresponding swing arm to ensure that the display body 3 can flip along the preset direction.

[0054] It should be understood that, in order to illustrate the orientation in this invention, the longitudinal direction of the guide beam 11 is taken as the front-to-back direction, the width direction of the guide beam 11 is the left-to-right direction, the longitudinal 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 longitudinal direction of the guide beam 11 can also be other directions, and this invention does not limit it.

[0055] In order for the upper end of the sliding rocker arm 21 to move along the length direction of the guide beam 11, in this embodiment, please refer to... Figure 1 , Figure 3 and Figure 5 The sliding flipping mechanism 2 further includes a sliding seat 22 corresponding to the sliding rocker arm 21. The sliding seat 22 moves linearly along the length of the guide beam 11. The upper end of the sliding rocker arm 21 is hinged to the sliding seat 22. Thus, by setting the sliding seat 22, the upper end of the sliding rocker arm 21 can move along the length of the guide beam 11. At the same time, the upper end of the sliding rocker arm 21 is hinged to the sliding seat 22 so that the upper end of the sliding rocker arm 21 rotates with the sliding seat 22, so that the sliding seat 22 slides.

[0056] 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 guide beam 11 has a groove 12 extending along its length on its inner side. A first slide rail 13 extending along its length is formed in the guide beam 11. A connecting channel is provided between the first slide rail 13 and the groove 12. The sliding seat 22 includes a sliding part 221, a traction part 222, and a connecting part 223 disposed between the sliding part 221 and the traction part 222. The connecting part 223 is disposed in the connecting channel, so that the sliding part 221 and the traction part 222 are respectively located in the groove 12 and the first slide rail 13. The upper end of the sliding rocker arm 21 is hinged to the sliding part 221. Under the action of the traction device, the traction part 222 is slidably installed along the first slide rail 13, so that the sliding part 221 is slidably installed in the slide groove 12. Thus, by setting the slide groove 12, the sliding part 221 can move in a straight line. By setting the connecting part 223 to connect the sliding part 221 and the traction part 222, the sliding part 221 can slide under the drive of the traction part 222. At the same time, by setting the first slide rail 13, the traction device can extend into the guide 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 beam 11.

[0057] Since the sliding part 221 needs to be hinged to the sliding rocker arm 21, and the rocker arm is located at the side end of the guide beam 11, the sliding part 221 needs to be set on the inner side of the guide beam 11 to connect with the sliding rocker arm 21. However, the fact that the sliding part 221 needs to be set on the inner side of the guide beam 11 will cause the upper and lower ends of the sliding part 221 to be subjected to inconsistent forces, so that the sliding part 221 is prone to flipping towards the inner side of the guide beam 11 when sliding. Therefore, in this embodiment, a limiting rib 121 is protruding from the inner wall surface of the groove 12. The sliding part 221 is set in a stepped manner to form a limiting step. The limiting step abuts against the limiting rib 121. In this way, the sliding part 221 is confined within the groove 12 by the mutually cooperating limiting step and the limiting rib 121 to prevent the sliding part 221 from flipping.

[0058] Theoretically, the two sliding rocker arms 21 can share the same first slide rail, but the two sliding seats 22 are prone to interference, causing them to not come together completely. Therefore, in this embodiment, two first slide rails 13 are provided and spaced apart along the width direction of the guide beam 11. Correspondingly, two sliding rocker arms 21 and two sliding seats 22 are provided, and the two sliding seats 22 are spaced apart along the length direction of the guide beam 11. The traction part 222 of each sliding seat 22 is respectively located in the two first slide rails 13. In this way, by providing two first slide rails 13, the two sliding seats 22 are located in different first slide rails 13, preventing the two sliding seats 22 from interfering with each other.

[0059] For ease of installation of the sliding seat 22, please refer to the following embodiment: Figure 5 and Figure 6 The guide 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 sliding groove 12 and the communicating channel. When the sliding seat 22 needs to be installed, the upper guide rail 111 is first removed, 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 beam 11. Thus, a detachable structure is adopted to facilitate the installation and removal of the sliding seat 22.

[0060] To prevent the sliding rocker arm 21 from disengaging from the guide 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, which is used to abut against the sliding seat 22. In this way, by setting the limiting step surface 1121, the sliding stroke of the sliding seat 22 is limited, and the sliding seat 22 is prevented from sliding off the guide rail beam 11.

[0061] When one of the sliding seats 22 at one end of the guide beam 11 is too close to the other sliding seat 22 at the other end of the guide beam 11, the span between the two sliding seats 22 is less than the span between the two sliding seats 22 when the display body 3 is in landscape mode. As a result, 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 of the guide beam 11 to limit the sliding stroke of the sliding seat 22, so as to prevent the sliding seat 22 at one end of the guide beam 11 from being too close to the other 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.

[0062] Since the force required to keep the display body 3 in a horizontal position is provided by the traction device driving the slide, the pulling force of the traction device is at its maximum under a constant gravity. However, the traction device is a flexible transmission mechanism 200 with relatively low strength. Prolonged 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 connects the sliding seat 22 and the corresponding sliding rocker arm 21. A torsion spring 24 is sleeved on the rotating mounting shaft 23. The torsion spring 24 is used to reset the sliding rocker arm 21 to rotate upward. In this way, by setting the torsion spring 24, part of the gravity is offset, thereby reducing the load on the flexible transmission mechanism 200 and 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 play a buffering role, making the flipping speed more uniform and gentle.

[0063] Furthermore, the sliding rocker arm 21 has a receiving groove at one end facing the sliding seat 22, and a fixing hole is provided on the side of the receiving groove. The guide beam 11 has an insertion hole on its end face facing the sliding rocker arm 21. The torsion spring 24 is disposed in the receiving groove, and its two ends are respectively inserted into the insertion hole and the fixing hole. In this way, by setting the fixing hole and the insertion hole, the two ends of the torsion spring 24 are respectively installed on the sliding seat 22 and the sliding rocker arm 21, so that the sliding rocker arm 21 deforms when it rotates, thereby offsetting part of the weight of the display body 3. At the same time, by setting the receiving groove, the torsion spring 24 is hidden in the sliding rocker arm 21, which can both protect the torsion spring 24 and improve the appearance of the flip display device 100.

[0064] To improve the appearance of the flip display device 100, specifically, in one embodiment, please refer to... Figure 1 , Figure 3 and Figure 4 The inner side of the guide beam 11 is provided with a cable routing tube 15 extending along its length. By providing the cable routing tube 15, the wire harness can be installed inside the guide beam 11, facilitating wire harness insertion and concealing the wire harness, preventing it from being directly exposed outside the mounting bracket 1, thereby improving the appearance of the flip display device 100. In another embodiment, please refer to... Figure 3 The sliding rocker arm 21 has a wiring groove 211. By providing the wiring groove 211, the wire harness is hidden inside the sliding rocker arm 21, which facilitates wire harness insertion and conceals the wire harness, preventing it from being directly exposed outside the sliding rocker arm 21, thereby improving the appearance of the flip display device 100. It should be noted that the two related technical features mentioned above—"the inner side of the guide beam 11 is provided with a wiring tube 15 extending along its length" and "the sliding rocker arm 21 has a wiring groove 211"—can be either chosen as one or both can be provided simultaneously. Obviously, providing both simultaneously is more effective.

[0065] Furthermore, to achieve the above objectives, the present invention also provides a display device, which includes the aforementioned flip display device 100. It should be noted that the structure of the flip display device 100 in the display device can refer to the embodiments of the aforementioned flip display device 100, and will not be repeated here. Since the aforementioned flip display device 100 is used in the display device provided by the present invention, the embodiments of the display device provided by the present invention include all the technical solutions of all embodiments of the aforementioned flip display device 100, and the achieved technical effects are also completely the same, and will not be repeated here.

[0066] Typically, a linear transmission mechanism is used to drive the sliding rocker arm 21. However, this increases the size of the display device in the direction of motion of the linear transmission structure, resulting in an excessively large display device that does not meet the requirements for thinness and narrowness in electronic product design. Therefore, to reduce the size of the display device, it is necessary to change the transmission direction. However, commonly used flexible transmission mechanisms such as chain drives or belt drives are only suitable for transmitting tensile forces and do not have a pushing effect, so they cannot be used to push the sliding rocker arm 21 to slide. Therefore, in this embodiment, please refer to... Figures 7 to 11 The display device further includes a flexible transmission mechanism 200, which includes a flexible transmission rod 4, a shaping tube 5, and a driving device 6. The flexible transmission rod 4 is deformable and bendable. 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 deform to adapt to the orientation of the shaping tube 5.

[0067] 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 drivenly connected to the sliding swing rod 21 of the flip display device 100. When the driving device 6 drives the flexible transmission rod 4 to move forward or backward along the length direction of the shaping tube 5, the flexible transmission rod 4 drives the sliding swing rod 21 to reciprocate along the length direction of the guide beam 11. Thus, by setting the flexible transmission rod 4, the flexible transmission mechanism 200 can not only turn and change the transmission direction, but also transmit thrust and pull forces, so that the driven structure can reciprocate. At the same time, by setting the shaping tube 5, the flexible transmission rod 4 can deform along a preset direction to change the transmission direction of the flexible transmission rod 4, reduce the driving stroke of the flexible transmission rod 4 in the length direction of the guide beam 11, which is beneficial to reduce the size of the display device, thereby making the display device suitable for limited spaces and improving the applicability of the display device.

[0068] There are various ways to drive the flexible transmission rod 4, such as by driving a cylinder or other methods. Specifically, in this embodiment, please refer to... Figure 8 , Figure 9 and Figure 11The flexible transmission rod 4 has a helical portion formed on its outer surface. The driving device 6 includes a rotatably mounted driving gear. The teeth of the driving gear mesh with the helical portion for transmission. When the driving gear rotates in the forward direction, the flexible transmission rod 4 moves forward along its length under the drive of the driving gear. When the driving gear rotates in the reverse direction, the flexible transmission rod 4 retracts along its length under the drive. Thus, through the meshing driving gear and the helical portion, the flexible transmission rod 4 can reciprocate along its length. Furthermore, the driving device 6 also includes a driving motor 61. The driving gear is driven and connected to the main shaft of the driving motor 61. Thus, by setting the driving motor 61 to drive the driving gear to rotate, the flexible transmission rod 4 reciprocates.

[0069] Further, please refer to Figure 7 , Figure 8 and Figure 11 The flexible transmission mechanism 200 further includes a mounting base 7, which has two opposing through-ends and two opposing mounting ends. One of the mounting ends has a mounting groove 71 on its end face, and one of the through-ends has a through-hole. The through-holes are laterally connected to the mounting groove 71. The shaping tube 5 is correspondingly inserted into the through-hole. The lateral opening 51 of the shaping tube 5 is provided so that the spiral part can be exposed in the mounting groove 71. The drive gear is rotatably mounted in the mounting groove 71. Thus, by providing the mounting groove 71, the drive motor 61 can drive the drive gear to rotate. By providing the through-hole, the shaping tube 5 can extend into the mounting groove 71. At the same time, by providing the lateral opening 51 of the shaping tube 5, the flexible transmission rod 4 in the shaping tube 5 can mesh with the drive gear, so that the flexible transmission rod 4 can reciprocate under the drive of the drive motor 61.

[0070] In order to drive the two flexible transmission rods 4 simultaneously, in this embodiment, the flexible transmission rods 4, the shaping tube 5 and the through hole are respectively configured as transmission groups. Two transmission groups are provided, and the spiral parts of the two transmission groups are spaced apart on both sides of the drive gear, so that the drive gear can drive the two flexible transmission rods 4 to reciprocate at the same time.

[0071] To enable the flexible transmission rod 4 to transmit thrust and tension, in this embodiment, the flexible transmission rod 4 includes a helical member 42 of the rod body 41 and an elastic connector 43. The helical member 42 is helically wound around the rod body 41, and the elastic connector 43 connects the rod body 41 and the helical member 42. The helical portion includes the helical member 42. Thus, by setting the rod body 41 to be thinner, the rod body 41 has a certain strength and toughness, making the flexible transmission rod 4 easy to bend and deform while transmitting thrust. The helical member 42 is provided to mesh with the drive gear. At the same time, the elastic connector 43 is provided to connect the rod body 41 and the helical member 42, thereby increasing the adhesion between the rod body 41 and the helical member 42, improving the frictional resistance between the rod body 41 and the helical member 42, and preventing the helical member 42 and the rod body 41 from sliding against each other.

[0072] Furthermore, the rod body 41 is made of spring steel. Because spring steel has good toughness and rigidity, uniform deformation, and rapid recovery, the use of spring steel allows the flexible transmission rod 4 to both bend and deform, and transmit push and pull forces, ensuring precise dimensional transmission while preventing problems such as breakage, stretching, bending, or stacking. Of course, the rod body 41 can also be made of materials such as rubber.

[0073] For ease of engagement with the drive gear, please refer to the following embodiment: Figure 8 and Figure 9 The spiral component 42 includes a spiral steel bar, so that the spiral portion is formed on the outer periphery of the rod body 41 to cooperate with the drive 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.

[0074] In order to connect the helical element 42 to the rod body 41, in this embodiment, please refer to... Figure 8 and Figure 9 The elastic connector 43 is made of plastic. Using plastic allows the rod body 41 to be wrapped during injection molding, increasing both the outer diameter of the rod body 41 for mounting the helical component 42 and providing additional rigidity. Of course, in other embodiments, the elastic connector 43 can also be made of rubber or similar materials.

[0075] It should be noted that the above three related technical features: "the material of the rod body 41 includes spring steel", "the spiral component 42 includes spiral steel bars", and "the material of the elastic connector 43 includes plastic" can be set individually or simultaneously. Obviously, setting them simultaneously will have a better effect.

[0076] To strengthen the connection between the rod body 41 and the elastic connector 43, in this embodiment, the rod body 41 and the elastic connector 43 are integrally injection molded. This allows the rod body 41 to be wrapped during the injection molding process, so that the rod body and the elastic connector 43 form a whole, thereby increasing the adhesive force between the rod body 41 and the connector and preventing relative sliding between the elastic connector 43 and the rod body 41.

[0077] To strengthen the connection between the rod body 41 and the elastic connector 43, in this embodiment, the outer peripheral side of the elastic connector 43 is provided with a spiral groove for the spiral member 42 to be wound around, so that the spiral member 42 can be embedded in the elastic connector 43, thereby increasing the sliding resistance between the spiral member 42 and the elastic connector 43, strengthening the connection between the spiral member 42 and the elastic connector 43, so that the spiral member 42 remains in a stable position under the action of the drive gear, and preventing the spiral member 42 and the elastic connector 43 from misaligning and sliding.

[0078] It should be noted that the two related technical features mentioned above, namely, "the rod body 41 and the elastic connector 43 are integrally injection molded" and "the outer peripheral side of the elastic connector 43 is provided with a spiral groove", can be set either one or both. Obviously, setting both at the same time is better.

[0079] To strengthen the connection between the rod body 41 and the elastic connector 43, in one embodiment, please refer to... Figure 9 The outer peripheral surface of the rod body 41 is provided with multiple grooves. At least some of the grooves are spaced apart circumferentially along the rod body 41, and / or at least some of the grooves are spaced apart axially along the rod body 41. Thus, by providing multiple grooves, the elastic connector 43 can be embedded within the rod body 41, thereby increasing the sliding resistance between the rod body 41 and the elastic connector 43 and preventing relative sliding between them. Furthermore, since the rod body 41 is relatively thin, providing the grooves would reduce its strength. If annular or strip grooves were used directly, it would have a significant impact on the rod body 41. Therefore, the grooves are spaced apart to minimize their impact on the strength of the rod body 41.

[0080] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
