Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a contactless control latch and display device. Background Technology

[0002] Commercial video walls are typically composed of multiple display units spliced ​​together. Specifically, this is achieved by connecting the cabinets of the display units to create a larger display area. To facilitate the connection of adjacent cabinets, latches are installed along the edges of the cabinets, and the driving components for these latches are located on the display modules. These driving components are usually positioned between two adjacent LEDs within the display module. Installation and maintenance personnel can directly perform cabinet splicing operations from the front of the screen, greatly improving the convenience of installation and maintenance.

[0003] However, as users' demands for screen display quality continue to increase, it is necessary to reduce the spacing between the LEDs on the display module to achieve a more refined display effect. But the driving components occupy the space between two adjacent LEDs, becoming an obstacle to further reducing the spacing between the LEDs and limiting the improvement of the display effect of the splicing screen. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a contactless control latch and display device to solve the problem that the current splicing screen latch affects the spacing of the screen LED beads.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A contactless control latch includes a drive component, a first mounting component, and a second mounting component;

[0007] The first mounting component is provided with a connecting rod;

[0008] The second mounting component is provided with a locking mechanism rotatably connected thereto, the locking mechanism having a locking hook;

[0009] The driving component and / or the locking mechanism are magnetic. The driving component drives the locking mechanism to rotate relative to the second mounting component in a first direction via magnetism, so that the locking hook is engaged with the connecting rod.

[0010] Preferably, the locking mechanism includes an eccentric wheel and a locking member, the eccentric wheel is rotatably connected to the second mounting component, the locking member is connected to the eccentric wheel, the locking member is provided with the locking hook, and the driving component and / or the eccentric wheel are magnetic;

[0011] When the locking hook is engaged with the connecting rod, the driving component continues to drive the eccentric wheel along the first direction, and the eccentric wheel and the locking member rotate relative to each other, so that the locking member and the first mounting component move towards each other or away from each other.

[0012] Preferably, the locking member is fitted to the rim of the eccentric wheel to create a preset frictional force between them. When the driving force of the driving component on the eccentric wheel is greater than the preset frictional force, the eccentric wheel and the locking member rotate relative to each other.

[0013] Preferably, the driving component includes a handle and a magnetic element disposed at one end of the handle.

[0014] Preferably, the driving component includes a housing with a through hole extending through it, the handle being rotatably inserted through the through hole, and the magnetic element being located inside the housing.

[0015] Preferably, the end of the handle forms a cover, the cover is made of metal, and the magnetic element is disposed inside the cover.

[0016] Preferably, the connecting rod is a cylindrical structure, and the axis of the connecting rod is parallel to the rotation axis of the locking mechanism.

[0017] Preferably, the inner wall surface of the locking hook is an inner cylindrical surface and is used to abut against the outer wall surface of the connecting rod;

[0018] A straight line passing through the axis of the inner cylindrical surface and tangent to the outer side wall of the connecting rod is defined as the first reference line. A plane is formed by the axis of the connecting rod and the rotation axis of the locking mechanism. The normal to the plane is defined as the second reference line. The included angle between the first reference line and the second reference line is 30° to 60°.

[0019] Preferably, the locking member is rotatably connected to the rim of the eccentric wheel via a connecting member with a constraint function, and the connecting member is a damped ratchet device;

[0020] When the locking hook moves in the first direction, the damping of the ratchet device causes the locking member and the eccentric wheel to rotate together; when the locking hook is engaged with the connecting rod, the ratchet device allows the locking member and the eccentric wheel to rotate relative to each other; when the locking hook moves in the second direction, the ratchet device prevents the locking member and the eccentric wheel from rotating relative to each other; the first direction and the second direction are opposite.

[0021] To solve the same technical problem, this utility model also provides a display device, including the contactless control latch as described above.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] The first mounting component is provided with a connecting rod, and the second mounting component is provided with a locking mechanism rotatably connected to it. The locking mechanism can rotate relative to the second mounting component to allow the locking hook on the locking mechanism to engage with the connecting rod. The driving component and / or the locking mechanism are magnetic. The driving component drives the locking mechanism to rotate without contact via magnetism, switching the locking and unlocking states of the locking mechanism. Even if there are other existing isolation structures between the driving component and the locking mechanism, the driving component can still drive the locking mechanism to rotate via magnetism. This structure can avoid adverse effects on the arrangement of LED beads in the display screen. Attached Figure Description

[0032] Example 1

[0033] Combination Figures 1 to 3 As shown, the contactless control latch of this utility model is schematically displayed, including a drive component 30, a first mounting component 10, and a second mounting component 20.

[0034] The first mounting component 10 and the second mounting component 20 are arranged opposite to each other. The first mounting component 10 is provided with a connecting rod 11, and the second mounting component 20 is provided with a locking mechanism 21 rotatably connected to it. The locking mechanism 21 has a locking hook 213. The locking mechanism 21 can rotate relative to the second mounting component 20 in a first direction, and the locking hook 213 can be hooked onto the connecting rod 11 to lock the first mounting component 10 and the second mounting component 20. The first direction can be... Figure 1 The locking mechanism 21 can rotate clockwise or counterclockwise. Conversely, if the locking mechanism 21 rotates relative to the second mounting component 20 in a second direction, the locking hook 213 can disengage from the connecting rod 11. The second direction is opposite to the first direction.

[0035] Combination Figure 3The driving component 30 and / or locking mechanism 21 are magnetic. The driving component 30 drives the locking mechanism 21 to rotate relative to the second mounting component 20 via the aforementioned magnetism, so that the locking hook 213 is engaged with the connecting rod 11. Even if there are other existing structures separating the driving component 30 and the locking mechanism 21 (such as product housing, display module), the driving component 30 can still drive the locking mechanism 21 to rotate via magnetism. Specifically, the driving component 30 and the locking mechanism 21 are magnetically attracted. The user applies force to rotate the driving component 30, thereby causing the locking mechanism 21 to rotate relative to the second mounting component 20. When a display module is provided between the driving component 30 and the locking mechanism 21, the first mounting component 10 and the second mounting component 20 (including other components on each mounting component) will not cause structural interference with the display module and will not affect the arrangement of the LEDs on the display module.

[0036] Furthermore, the locking mechanism 21 includes an eccentric wheel 211 and a locking member 212. The eccentric wheel 211 is rotatably connected to the second mounting component 20, and the locking member 212 is connected to the eccentric wheel 211. The locking member 212 is provided with a locking hook 213, and the driving component 30 and / or the eccentric wheel 211 are magnetic. When the locking hook 213 is engaged with the connecting rod 11, the driving component 30 continues to drive the eccentric wheel 211 in the first direction. The eccentric wheel 211 and the locking member 212 rotate relative to each other so that the locking member 212 and the first mounting component 10 move towards or away from each other. That is, when the eccentric wheel 211 and the locking member 212 rotate relative to each other, the locking member 212 performs an eccentric movement. The eccentric wheel 211 is located at one end of the locking member 212, and the locking hook 213 is located at the other end of the locking member 212.

[0037] like Figure 2 When the user needs to lock the first mounting component 10 and the second mounting component 20, force is applied to rotate the drive component 30. The drive component 30 magnetically drives the eccentric wheel 211 to rotate relative to the second mounting component 20. Before the locking hook 213 is engaged with the connecting rod 11, the eccentric wheel 211 drives the locking member 212 to rotate together in the first direction, so that the locking hook 213 on the locking member 212 is engaged with the connecting rod 11. Then the user can continue to apply greater force to rotate the drive component 30, and the connecting rod 11 will prevent locking. As the locking member 212 continues to rotate relative to the second mounting member 20, the user applies a greater torque, causing the eccentric wheel 211 and the locking member 212 to rotate relative to each other. The eccentric wheel 211 drives the locking member 212 to make an eccentric movement, and causes the locking member 212 to move in a direction away from the first mounting member 10. The locking hook 213 gradually begins to pull the connecting rod 11, and the squeezing force between the two gradually increases. The locking hook 213 is firmly hooked onto the connecting rod 11, and the connection between the first mounting member 10 and the second mounting member 20 becomes tighter.

[0038] like Figure 1When the user needs to unlock the first mounting component 10 and the second mounting component 20, the drive component 30 is rotated in the second direction. The drive component 30 drives the eccentric wheel 211 to rotate relative to the second mounting component 20 in the second direction via magnetic drive. The eccentric wheel 211 drives the locking component 212 to make eccentric movement and moves the locking component 212 toward the first mounting component 10. The squeezing force between the locking hook 213 and the connecting rod 11 gradually decreases. As the eccentric wheel 211 continues to rotate, the connection between the locking hook 213 and the connecting rod 11 is loosened. The eccentric wheel 211 and the locking component 212 begin to rotate synchronously in the second direction and cause the locking hook 213 to disengage from the connecting rod 11.

[0039] In this embodiment, the locking member 212 is attached to the rim of the eccentric wheel 211 to create a preset frictional force between them. When the driving force of the driving component 30 on the eccentric wheel 211 is greater than the preset frictional force, the eccentric wheel 211 and the locking member 212 rotate relative to each other. Conversely, when the driving force of the driving component 30 on the eccentric wheel 211 is less than or equal to the preset frictional force, the eccentric wheel 211 and the locking member 212 rotate synchronously.

[0040] More specifically, the driving component 30 includes a handle 31 and a magnetic element 32 disposed at one end of the handle 31. The user holds the handle 31 to drive the magnetic element 32 to rotate, thereby driving the locking mechanism 21 to rotate. To protect the magnetic element 32, the driving component 30 also includes a housing 33. The housing 33 has a through hole 331 extending through it. The handle 31 is rotatably inserted through the through hole 331, and the magnetic element 32 is located inside the housing 33. The end of the handle 31 forms a cover 311. The handle 31 and the cover 311 are made of metal and are integrally formed. The magnetic element 32 is disposed inside the cover 311. This structure of the handle 31 can enhance the magnetic field of the magnetic element 32.

[0041] The connecting rod 11 has a cylindrical structure, and its axis is parallel to the rotation axis of the locking mechanism 21. The cylindrical structure of the connecting rod 11 provides better fit with the locking hook 213, specifically resulting in smoother engagement and disengagement between the connecting rod 11 and the locking hook 213. Correspondingly, the inner wall surface of the locking hook 213 is an inner cylindrical surface used to abut against the outer wall of the connecting rod 11. A straight line passing through the axis of the inner cylindrical surface and externally tangent to the outer wall of the connecting rod 11 is defined as the first reference line A. A plane is formed by the axis of the connecting rod 11 and the rotation axis of the locking mechanism 21, and the normal to this plane is defined as the second reference line B. The included angle between the first reference line A and the second reference line B is 30° to 60°, for example, 30°, 35°, 40°, 45°, 50°, 55°, 60°, preferably 51°, making it less likely for the locking hook 213 to fall off after being engaged with the connecting rod 11.

[0042] Example 2

[0043] The difference between this embodiment and embodiment 1 is that the locking member 212 is rotatably connected to the rim of the eccentric wheel 211 through a connecting member with a constraint function, and the connecting member is a damped ratchet device.

[0044] The locking hook 213 has an opening 213a. When the opening 213a of the locking hook 213 moves toward the connecting rod 11 (the locking member 212 rotates relative to the second mounting member 20 in the first direction), the damping of the ratchet device causes the locking member 212 and the eccentric wheel 211 to rotate together.

[0045] When the locking hook 213 is engaged with the connecting rod 11, the ratchet device allows the locking member 212 and the eccentric wheel 211 to rotate relative to each other. That is, when the locking hook 213 is engaged with the connecting rod 11, the connecting rod 11 prevents the locking member 212 from continuing to rotate. The torque applied by the user to the eccentric wheel 211 breaks through the damping constraint and causes the eccentric wheel 211 and the locking member 212 to rotate relative to each other. At this time, the ratchet device allows the eccentric wheel 211 and the locking member 212 to rotate relative to each other, so that the locking hook 213 is tightly engaged with the connecting rod 11.

[0046] Conversely, when the opening 213a of the locking hook 213 moves away from the connecting rod 11 (the locking member 212 rotates relative to the second mounting member 20 in the second direction), the ratchet device prevents the locking member 212 from rotating relative to the eccentric wheel 211, ensuring that the locking member 212 can disengage from the connecting rod 11 normally.

[0047] Example 3

[0048] like Figure 4 This embodiment discloses a display device 1, including a first housing 40, a second housing 50, and a contactless control latch as described above. A first mounting component 10 is disposed on the first housing 40, and a second mounting component 20 is disposed on the second housing 50.

[0049] Display modules are respectively provided on the first housing 40 and the second housing 50. Adjacent first housings 40 and second housings 50 can be spliced ​​together to form a larger display screen. The locking member 212 on the second mounting component 20 rotates so that the locking hook 213 is hooked onto the connecting rod 11 on the first mounting component 10, thereby realizing the locking and splicing of the first housing 40 and the second housing 50.

[0050] In summary, the first mounting component 10 is provided with a connecting rod 11, and the second mounting component 20 is provided with a locking mechanism 21 rotatably connected to it. The locking mechanism 21 can rotate relative to the second mounting component 20 so that the locking hook 213 on the locking mechanism 21 can be hooked onto the connecting rod 11. The driving component 30 and / or the locking mechanism 21 are magnetic. The driving component 30 drives the locking mechanism 21 to rotate without magnetic contact, switching the locking state and unlocking state of the locking mechanism 21. Even if there are other existing isolation structures between the driving component 30 and the locking mechanism 21, the driving component 30 can still drive the locking mechanism 21 to rotate magnetically. This structure can avoid adverse effects on the arrangement of the display lamp beads.
