Description

Technical Field

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

[0002] With the rapid development of the LED industry, LED displays are being used more and more widely. Transparent LED displays need to switch between transparency and light blocking in certain application scenarios to block and display background light, thereby enhancing the overall sense of layering. Therefore, accessories that can achieve both light blocking and light transmission are required.

[0003] The light-shielding and light-transmitting accessories in related technologies are designed separately from the display screen, which not only takes up more space but also has a more complex structure and a cumbersome light switching process. Summary of the Invention

[0004] In view of the above problems, this application provides a display device that aims to reduce the space occupied by the dimming component, making the structure simpler, the operation easier, and improving the switching speed between light blocking and light transmission, thereby improving efficiency.

[0005] To solve the above problems, the display device of this application includes a display screen and a dimming component disposed on the display screen, wherein the display screen and the dimming component are an integral structure; The dimming component includes: Multiple blades, the blades including a first state and a second state, the first state being a closed state in which at least part of the light is blocked from reaching the display screen, and the second state being an open state in which at least part of the light can reach the display screen; A linkage component, used to drive multiple blades to move synchronously, the linkage component includes a first position and a second position along its own length direction, wherein when the linkage component is in the first position, the blade is in a first state, and when the linkage component is in the second position, the blade is in a second state; and A control element, connected to and used to drive the linkage element to switch the linkage element between the first position and the second position.

[0006] The advantage of this embodiment is that, in related technologies, the display screen and the dimming structure are separate units, which are located on one side of the display screen and occupy a large space. Moreover, the adjustment process of the dimming structure is complicated. The solution of this embodiment makes the dimming component and the display screen an integrated structure, thereby increasing the integration between the dimming component and the display screen and reducing the space occupation. At the same time, this embodiment can realize the synchronous movement of all blades by simply operating the control component, realizing the conversion and adjustment of light blocking and light transmission. The operation process is simple and quick, which can improve the efficiency of use and the structure is more simplified.

[0007] In one embodiment, the dimming assembly further includes a support extending along the arrangement direction of the plurality of blades, a linkage extending along the arrangement direction of the plurality of blades, the linkage being slidably disposed relative to the support to switch between a first position and a second position, the blades being rotatably connected to the support, the linkage being used to drive the blades to swing, and the support being connected to the display screen.

[0008] This embodiment provides a support member and a skeleton for the dimming assembly. Its advantages are that it enables the connection with the display screen, the installation of the blades (allowing the blades to rotate), and the installation of the linkage, allowing the linkage to interact with the blades. The support member has a simple structure, which can be just a rod structure. The support member integrates and connects multiple structures, reducing space occupancy and thus reducing the structural complexity of the entire dimming assembly. It enables linkage switching and simplifies the operation process.

[0009] In one embodiment, the linkage is provided with a plurality of push tops at intervals, and the plurality of push tops are arranged in a one-to-one correspondence with the plurality of blades. The push tops move with the linkage to drive the corresponding blades to swing.

[0010] The advantage of this embodiment is that a push-top is provided on the linkage component. The push-top can be an integral structure with the linkage component. It is not a structure mechanically connected to the linkage component, but rather a push-top position formed based on the structural form of the linkage component. Specifically, it can be a convex structure, a hook-shaped structure, a concave structure, or even a toothed structure. The push-top can push the blades, eliminating the need to specially connect and set corresponding structures on the linkage component. Instead, the push-top is formed based on the structure of the linkage component itself, which simplifies the structure, reduces the space occupation rate, and facilitates operation.

[0011] In one embodiment, the push top is a protrusion provided on the linkage.

[0012] The advantage of this embodiment is that the push top formed by the shape of the linkage itself is a protrusion, that is, the push top is set as a protrusion. The protrusion is a structure that protrudes from the surface of the linkage. It has no complicated structural form and surface shape. As long as it protrudes from the linkage, it can perform the corresponding push. Therefore, this embodiment does not use a complicated push assembly structure, which can realize the action of each blade and further simplify the structure.

[0013] In one embodiment, the dimming assembly further includes a plurality of cam assemblies, each of which is correspondingly arranged with and connected to the blade. The blade is rotatably connected to the support member through the cam assembly, and the linkage member is used to drive the cam assembly to rotate so that the blade swings.

[0014] The advantage of this embodiment is that it provides a cam assembly connected to the blade. The blade can be oscillated by the rotation or oscillation of the cam assembly. Since the blade is a plate-like structure, in order to better drive its oscillation, a cam assembly is used instead of directly driving the blade. Directly driving the cam assembly is easier to operate, and the protrusion can also better contact the cam assembly to trigger the cam assembly to move. Therefore, the linkage is more likely to interact with the cam assembly during the movement. Compared with directly driving the blade to rotate, the effect is more direct and effective.

[0015] In one embodiment, the cam assembly includes a cam and a rocker arm connected to the cam, the cam being rotatably connected to the support member, the linkage member being used to drive the cam to rotate, and the rocker arm being used to actuate the blade.

[0016] The advantage of this embodiment is that it provides a cam assembly structure, including a cam and a rocker arm connected to the cam. The cam rotates, and the rocker arm swings. The rocker arm is used to directly actuate the blade. Since the rocker arm swings, it is equivalent to converting the linear motion of the linkage into the swing of the rocker arm. The pusher is more likely to interact with the cam, and the rocker arm is more likely to interact with the blade. Therefore, the linkage can more easily drive the blade to swing through the cam assembly, improving operating efficiency and stability.

[0017] In one embodiment, the control element includes a gear rotatably connected to the support member, and the linkage member has external teeth arranged along its length direction, the gear meshing with the external teeth, and the gear driving the linkage member to move.

[0018] The advantage of this embodiment is that, compared with directly pushing the linkage, driving the linkage with gears is more convenient and stable, and has better controllability. The stroke of the linkage can be determined according to the rotation angle of the gear, so that the linkage can be accurately moved to the first position and the second position, and the controllability is better.

[0019] In one embodiment, the control element further includes a lever connected to the gear to drive the gear to rotate.

[0020] The advantage of this embodiment is that the joystick is designed to make it easier to drive the gears to rotate, which is equivalent to increasing the operating torque and making the operation more effortless. At the same time, the rotation angle of the gears can be judged according to the swing amplitude of the joystick, which is more intuitive and further increases the controllability.

[0021] In one embodiment, the dimming assembly further includes a limiting mechanism for limiting the linkage to the first position or the second position.

[0022] The effect of this embodiment is that, since the linkage is movable, it needs to be kept in the first position and the second position so that the blade can maintain its state. The function of the limiting mechanism in this embodiment is to lock the linkage in a specific position on its stroke, specifically the first position or the second position, so that the blade can be kept in a state of light blocking or light transmission, so that the display screen can be kept in the scene of its required lighting requirements.

[0023] In one embodiment, the limiting mechanism includes: A pin, which slidably passes through the linkage; and An elastic element is provided to push the pin so that the pin abuts against the wall of the support member. The wall of the support member is provided with a limiting hole. When the linkage member is in the first position or the second position, at least a portion of the pin enters the limiting hole.

[0024] The advantage of this embodiment is that, in order to limit the linkage to a specific position in the stroke, this embodiment provides a pin. The linkage is fixed relative to the support by the pin cooperating with the limiting hole on the support wall, thereby limiting the linkage. This limiting form has a simple structure and is easy to assemble. It can be achieved by pushing the pin with the elastic element, which makes the structure more simplified.

[0037] The application of LED displays is becoming increasingly widespread, and the forms of displays are diverse. Transparent LED displays require switching between transparency and light blocking in some scenarios to achieve background light blocking and display. In order to meet this requirement, a light blocking component is temporarily set on one side of the display. The setting of the light blocking component occupies space, increasing the space occupied by the display in the application scenario. Moreover, the structure of the light blocking component is complex, and the operation process between light blocking and light transmission is cumbersome, reducing efficiency.

[0038] Based on this, this application provides a display device that aims to reduce the space occupied by the dimming component 1, making the structure simpler, the operation easier, and improving the switching speed between light blocking and light transmission, thereby increasing efficiency.

[0039] Please see Figures 1-12 This application provides a specific embodiment of a display device, which includes a display screen and a dimming component 1 disposed on the display screen, wherein the display screen and the dimming component 1 are an integral structure.

[0040] The dimming assembly 1 includes multiple blades 12, linkage components 13, and control components 14.

[0041] The multiple blades 12 include a first state and a second state. The first state is a closed state in which at least part of the light is blocked from reaching the display screen, and the second state is an open state in which at least part of the light can reach the display screen. The linkage 13 is used to drive the multiple blades 12 to move synchronously. The linkage 13 includes a first position and a second position along its own length direction. When the linkage 13 is in the first position, the blades 12 are in the first state. When the linkage 13 is in the second position, the blades 12 are in the second state. The control member 14 is connected to the linkage 13 and is used to drive the linkage 13 so that the linkage 13 switches between the first position and the second position.

[0042] Specifically, the display device in this embodiment includes a display screen and a dimming component 1. The display screen can be an LED display screen, specifically a transparent LED display screen. The dimming component 1 and the display screen are an integrated structure. The integrated structure means that the dimming component 1 and the display screen are connected, rather than being a separate structure set on the side of the display screen, which can reduce the space occupied.

[0043] In this embodiment, there are multiple blades 12. Each blade 12 can be understood as a sheet-like structure with a certain area, made of a light-blocking material. The blades 12 are disposed on one side of the display screen, and the multiple blades 12 are arranged along a certain direction and move synchronously. The first state refers to all blades 12 being closed, so that at least some light cannot pass through, thereby reducing the light reaching the display screen. The second state refers to all blades 12 rotating by a certain angle, specifically 90 degrees, so that all blades 12 are parallel to each other, with gaps between adjacent blades 12 allowing light to pass through, so that at least some light can reach the display screen on one side. Therefore, all blades 12 can move synchronously, realizing the switching between the first and second states.

[0044] Linkage component 13 refers to the intermediate linkage structure located between control component 14 and blade 12 in the connection structure. The linkage component 13 is activated by the action of control component 14, and the action of linkage component 13 will drive all blades 12 to move.

[0045] In order to enable the linkage 13 to drive all the blades 12 at once during operation, the linkage 13 in this embodiment can be a component with a certain length, which extends along the arrangement direction of all the blades 12, so that it can act on each blade 12. The linkage 13 can be operated by the control member 14, which can be the movement of the linkage 13 along its own length direction. This operation process can be continuous, but the linkage 13 needs to include at least two specific positions, namely the first position and the second position.

[0046] As an example, the first position can be the initial position of the linkage 13. When the linkage 13 is in the initial position without movement, all blades 12 can be in a closed state, i.e., the first state, so that a certain degree of light blocking can be achieved. The linkage 13 moves under the drive of the controlled member 14 and eventually reaches the second position. Therefore, the second position can be the final position of the linkage 13 in a one-way movement. During the movement, the linkage 13 can drive the blades 12 to change state. When the second position is reached, the blades 12 finally reach the second state, so that at least some light can pass through. Similarly, when the linkage 13 moves from the second position to the first position, the linkage 13 can drive the blades 12 to switch from the second state to the first state. Or, in some cases, after the linkage 13 changes position and releases the restriction on the blades 12, the blades 12 can also return to the first state under their own weight.

[0047] The control element 14 and the linkage element 13 can be mechanically connected, and the linkage element 13 and the blades 12 can also be mechanically connected. The switching process between the first and second states of all blades 12 can be achieved by the action of the control element 14. The control element 14 can be a manual element, a component that can be driven by hand.

[0048] The advantage of this embodiment is that, in related technologies, the display screen and the dimming structure are separate units, which are located on one side of the display screen and occupy a large space. Moreover, the adjustment process of the dimming structure is complicated. The solution of this embodiment makes the dimming component 1 and the display screen an integrated structure, thereby increasing the integration between the dimming component 1 and the display screen and reducing the space occupation. At the same time, this embodiment can realize the synchronous movement of all blades 12 by operating the control component 14, realizing the conversion and adjustment of light blocking and light transmission. The operation process is simple and quick, which can improve the efficiency of use and the structure is more simplified.

[0049] Please see Figures 5-12 According to some embodiments of this application, the dimming assembly 1 further includes a support member 15, which extends along the arrangement direction of the plurality of blades 12, and a linkage member 13 extends along the arrangement direction of the plurality of blades 12. The linkage member 13 is slidably disposed relative to the support member 15 to switch between a first position and a second position. The blades 12 are rotatably connected to the support member 15. The linkage member 13 is used to drive the blades 12 to swing, which can make the blades present a first state or a second state. The support member 15 is connected to the display screen.

[0050] Specifically, the support member 15 can be a slender rod-shaped structure, which acts as a supporting frame. Firstly, it can be used to connect the display screen, making the dimming component 1 and the display screen integrated. Specifically, the support member 15 can be directly connected to the display screen, or a surrounding frame structure can be provided. The surrounding frame structure is located around the support member 15 and the blade 12, with the support member 15 connected to the surrounding frame structure, and the support member 15 connected to the display screen through the surrounding frame structure. The support member 15 can be set along the height direction of the display screen and connected to one side of the display screen. The number of support members 15 can be set as needed. For example, two support members 15 can be set, arranged parallel to each other, located on opposite sides of the display screen, or three support members 15 can be set, parallel to each other. In addition to the two located on opposite sides of the display screen, an additional one can be added in the middle to increase the strength of the connection. Secondly, the support member 15 provides an mounting structure for the blade 12. The blade 12 includes a first state and a second state. The switching process between the first state and the second state can be a swinging switching of the blade 12. Therefore, the blade 12 can be rotatably connected to the support member 15, thereby enabling it to swing. The support member 15 can extend along the arrangement direction of the blade 12, thereby connecting to each blade 12. When there are multiple support members 15, the blade 12 can be selectively rotatably connected to each support member 15 simultaneously. Thirdly, the support member 15 also provides an installation position for the linkage member 13. The linkage member 13 can be slidably connected to the support member 15, thereby allowing the linkage member 13 to move along its own length direction. That is, the linkage member 13 can maintain the same extension direction as the support member 15, driving the blade 12 to swing during the movement. When there are multiple support members 15, the linkage member 13 can be selectively slidably connected to one of the support members 15, specifically, it can be connected to the support member 15 in the middle position.

[0051] This embodiment provides a support member 15, which serves as the skeleton of the dimming assembly 1. Its effect is to realize the connection with the display screen, to install the blade 12 so that the blade 12 can rotate, and to install the linkage member 13 so that the linkage member 13 can interact with the blade 12. The support member 15 has a simple structure, which can be just a rod structure. The support member 15 realizes the integrated connection between multiple structures, which can reduce the space occupation rate and reduce the structural complexity of the entire dimming assembly 1. It can realize linkage switching and simplify the operation process.

[0052] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12According to some embodiments of this application, the linkage member 13 is provided with a plurality of push tops 131 at intervals, and the plurality of push tops 131 are provided in a one-to-one correspondence with a plurality of blades 12. The push tops 131 move with the linkage member 13 to drive the corresponding blades 12 to swing.

[0053] Specifically, the linkage 13 can be a rod structure extending along the arrangement direction of the blades 12. During operation, it needs to touch each blade 12, causing the blades 12 to swing. To achieve this, this embodiment provides push tops 131. Push tops 131 can be components set on the linkage 13, whose function is to touch the blades 12 when the linkage 13 moves, thereby causing the blades 12 to swing. The number of push tops 131 is the same as the number of blades 12, and they can be set in a one-to-one correspondence. In this way, when the linkage 13 moves, each push top 131 moves along with it and simultaneously drives the corresponding blade 12 to swing, realizing the switching of the state of the blades 12.

[0054] The advantage of this embodiment is that a push-top 131 is provided on the linkage 13. The push-top 131 can be an integral structure with the linkage 13. It is not a structure mechanically connected to the linkage 13, but a push-top position formed based on the structural form of the linkage 13. Specifically, it can be a convex structure, a hook structure, a concave structure, or even a toothed structure. The push-top 131 can push the blade 12, without the need to specially connect and set a corresponding structure on the linkage 13. Instead, the push-top 131 is formed based on the structure of the linkage 13 itself, which simplifies the structure, reduces the space occupation rate, and facilitates operation.

[0055] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12 In some embodiments, the push top 131 is a protrusion provided on the linkage 13.

[0056] Specifically, the pusher 131 is a raised structure, that is, the linkage 13 is not flat in its length direction, but has multiple protrusions at intervals, and each protrusion corresponds to pushing a blade 12.

[0057] As an example, each protrusion may include two protruding blocks or rods arranged side by side with a gap between them. The two protrusions or rods may be located on both sides of the blade 12 respectively. The two protrusions or rods may slide in contact with both sides of the blade 12. When the linkage 13 moves, one of the protrusions or rods can move the blade 12 from the first state to the second state. When the linkage 13 moves back, the other protrusion or rod can move the blade 12 from the second state to the first state.

[0058] Alternatively, in some cases, when the blade 12 switches from the first state to the second state, or from the second state to the first state, if the switching can be achieved by gravity, the protrusion only needs to act on the blade 12 to overcome the switching process of gravity. After the protrusion moves back with the linkage 13, the blade 12 can also be reset under its own weight.

[0059] The advantage of this embodiment is that the push top 131 formed based on the shape of the linkage 13 itself is a protrusion, that is, the push top 131 is set as a protrusion. The protrusion is a structure that protrudes from the surface of the linkage 13. It has no complicated structural form and surface shape. It can be pushed accordingly by protruding from the linkage 13. Therefore, this embodiment does not adopt a complicated push assembly structure, and can realize the action of each blade 12, which further simplifies the structure.

[0060] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12 In some embodiments, the dimming assembly 1 further includes a plurality of cam assemblies 16, which are arranged one-to-one with the blades 12 and connected to each other. The blades 12 are rotatably connected to the support member 15 through the cam assemblies 16, and the linkage member 13 is used to drive the cam assemblies 16 to rotate so that the blades 12 swing.

[0061] Specifically, to facilitate the rotation of the blade 12 by the linkage 13, this embodiment provides that the blade 12 is rotatably connected to the support member 15 via the cam assembly 16. As can be seen from the above embodiment, multiple support members 15 can be provided, and only one linkage 13 can be provided. The linkage 13 can be slidably configured relative to one of the support members 15. The blade 12 can be rotatably connected between the cam assembly 16 and the support member 15 slidably configured relative to the linkage 13, while it can be directly rotatably connected to the other support members 15. The function of the cam assembly 16 is to facilitate the rotation of the blade 12 by the linkage 13 driving the cam assembly 16 to rotate. When the cam assembly 16 rotates under the drive of the linkage 13, the cam assembly 16 can cause the blade 12 to rotate.

[0062] The advantage of this embodiment is that it provides a cam assembly 16 connected to the blade 12. The blade 12 can be oscillated by the rotation or oscillation of the cam assembly 16. Since the blade 12 is a plate-like structure, the cam assembly 16 is used to drive its oscillation in order to better drive it, instead of directly driving the blade 12. Directly driving the cam assembly 16 is easier to operate, and the protrusion can also better contact the cam assembly 16 to trigger the action of the cam assembly 16. Therefore, the linkage 13 is more likely to interact with the cam assembly 16 during the movement. Compared with directly driving the blade 12 to rotate, the effect is more direct and effective.

[0063] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12 In some embodiments, the cam assembly 16 includes a cam 161 and a rocker arm 162 connected to the cam 161. The cam 161 is rotatably connected to the support member 15. The linkage member 13 is used to drive the cam 161 to rotate. The rocker arm 162 is used to actuate the blade 12.

[0064] Specifically, cam 161 is rotatably connected to support 15, and rocker arm 162 is connected to cam 161. When cam 161 rotates, rocker arm 162 swings, thereby causing blade 12 to swing. Because cam 161 is a non-circular wheel, it is more likely to come into contact with the moving linkage 13, thereby driving cam 161 to rotate.

[0065] When the cam 161 rotates, the rocker arm 162 swings. In some cases, the rocker arm 162 actuates the blade 12 to swing against gravity to reach a first or second state. When the cam 161 rotates back, the rocker arm 162 disengages from the blade 12, and the blade 12 can also return to its original state under the action of gravity. Alternatively, in other cases, when the swing of the blade 12 is unrelated to overcoming gravity, two rocker arms 162 spaced apart from each other can be connected to the cam 161. The two rocker arms 162 are used to actuate the two sides of the blade 12 respectively. When the cam 161 rotates, one rocker arm 162 actuates the blade 12, and when the cam 161 rotates back, the other rocker arm 162 deflects the blade 12.

[0066] Cam 161 is a non-circular wheel, which allows for better interaction with the linkage 13. The protruding wheel portion effectively increases the torque, making it easier to drive cam 161. Specifically, a pusher 131 can be provided on the linkage 13. The pusher 131 can be a structure with a certain degree of elasticity, providing a certain compressive force with cam 161. When the linkage reciprocates, the pusher 131 can drive cam 161 to rotate and turn. Alternatively, as an example, the pusher 131 can include two protruding structures, with cam 161 located between them. When the linkage 13 moves in one direction, one protruding structure pushes cam 161; when the linkage 13 moves in the other direction, the other protruding structure pushes cam 161.

[0067] This embodiment provides a structure for a cam assembly 16, including a cam 161 and a rocker arm connected to the cam 161. The cam 161 rotates, and the rocker arm 162 oscillates. The rocker arm 162 is used to directly actuate the blade 12. Since the rocker arm 162 oscillates, it is equivalent to converting the linear motion of the linkage 13 into the oscillation of the rocker arm 162. The pusher 131 is more likely to interact with the cam 164, and the rocker arm 162 is more likely to interact with the blade 12. Therefore, the linkage 13 can more easily drive the blade 12 to oscillate through the cam assembly 16, improving operating efficiency and stability.

[0068] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12 In some embodiments, the control member 14 includes a gear 141 rotatably connected to the support member 15, and the linkage member 13 is provided with external teeth 143 arranged along its length direction. The gear 141 meshes with the external teeth 143, and the gear 141 is used to drive the linkage member 13 to move. This allows it to switch between a first position and a second position.

[0069] Specifically, the control element 14 may include a gear 141, which is rotatably connected to the support element 15. The gear 141 can rotate, and through the rotation, the linkage element 13 is moved by the transmission of the gear 141. The linkage element 13 can be rod-shaped, with external teeth 143 arranged along the length direction of the rod, so that the linkage element 13 can move along the length direction.

[0070] To facilitate the installation of the linkage 13, the support 15 can be designed as a hollow structure, i.e., it has an inner cavity. The linkage 13 can be installed in the inner cavity, but one side of the support 15 is open to avoid the linkage structure between the linkage 13 and the blade 12.

[0071] The advantage of this embodiment is that, compared with directly pushing the linkage 13, driving the linkage 13 through the gear 141 is more convenient and stable, and has better controllability. The stroke of the linkage 13 can be determined according to the rotation angle of the gear 141, so that the linkage 13 can be accurately moved to the first position and the second position, and the controllability is better.

[0072] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12 In some embodiments, the control element 14 further includes a control lever 142 connected to the gear 141 to drive the gear 141 to rotate.

[0073] Specifically, the control lever 142 is rod-shaped, with one end connected to the gear 141, specifically to the axle of the gear 141, and the other end being a free end. The control lever 142 can be held by hand to drive the gear 141 to rotate.

[0074] The advantage of this embodiment is that the control lever 142 makes it easier to drive the gear 141 to rotate, which is equivalent to increasing the operating torque and making the operation more effortless. At the same time, the rotation angle of the gear 141 can be judged according to the swing amplitude of the control lever 142, which is more intuitive and further increases the controllability. In some cases, a notch can also be provided on the blade 12 to avoid the control lever 142 or the support member 15.

[0075] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12 In some embodiments, the dimming assembly 1 further includes a limiting mechanism for limiting the linkage 13 to a first position or a second position.

[0076] Specifically, when the linkage 13 is limited to the first position or the second position, the blade 12 can remain in the first state and the second state.

[0077] The effect of this embodiment is that, since the linkage 13 is movable, it needs to be kept in the first position and the second position so that the blade 12 can maintain its state. The function of the limiting mechanism in this embodiment is to lock the linkage 13 in a specific position on its stroke, specifically the first position or the second position, so that the blade 12 can be kept in a light-blocking or light-transmitting state, so that the display screen can be kept in the required lighting scene.

[0078] Please see Figure 7 , Figure 8 as well as Figure 11 and Figure 12 In some embodiments, the limiting mechanism includes a pin 17 and an elastic element.

[0079] The pin 17 slides through the linkage 13; the elastic member is used to push the pin 17 so that the pin 17 abuts against the wall of the support member 15. The wall of the support member 15 is provided with a limiting hole 18. When the linkage 13 is in the first position or the second position, at least part of the pin 17 enters the limiting hole 18.

[0080] Specifically, the linkage 13 and the support 15 are slidably arranged relative to each other. To ensure their relative fixation, a locking component is needed between them. The pin 17 serves as this locking component. Under the action of the elastic element, the pin 17 contacts the wall of the support 15 and exerts a certain compressive force. When the linkage 13 reaches the first or second position, the pin 17 can engage with the limiting hole 18, thereby limiting the linkage 13 to the first or second position, keeping the blade 12 in a closed or open state. When the limiting is released, the pin 17 can be pushed out of the limiting hole 18, allowing it to move again.

[0081] The advantage of this embodiment is that, in order to limit the linkage 13 to a specific position in its stroke, this embodiment provides a pin 17. The linkage 13 is fixed relative to the support 15 by the pin 17 cooperating with the limiting hole 18 on the wall of the support 15, thereby limiting the linkage 13. This limiting form has a simple structure and is easy to assemble. It can be achieved by pushing the pin 17 with the elastic element, which makes the structure more simplified.
