Description

Technical Field

[0001] The utility model relates to the technical field of display devices, in particular to an anti-collision device and a display device. Background Art

[0002] Interfaces for plugging in external USB drives, cables and other plug-in devices are usually provided on display devices to achieve data transmission between devices. Some existing display devices are combined with traditional blackboards, and the blackboard can be pushed and pulled relative to the display device.

[0003] However, during the process of pushing and pulling the blackboard, it is easy to collide with plug-in devices such as USB drives inserted into the interface, resulting in damage to the plug-in device or the interface. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an anti-collision device and a display device for the above problems to prevent damage to the plug-in device or the interface caused by pushing and pulling the blackboard.

[0005] The utility model first provides an anti-collision device, including a display device. The display device includes a display unit and a movable plate capable of moving relative to the display unit. The display unit is provided with an interface. The anti-collision device includes: a fixing member for being disposed on one side of the interface; a telescopic member disposed on the fixing member and capable of reciprocating relative to the fixing member. The telescopic member includes an extending portion capable of extending / retracting from the fixing member. In the extended state, at least a part of the extending portion is located on the movement path of the movable plate; and a driving assembly disposed on the fixing member. The driving assembly is used for being electrically connected to the display device and capable of driving the telescopic member to reciprocate relative to the fixing member.

[0006] In the above anti-collision device, when a plug-in device is inserted into the interface, the display device recognizes the signal and controls the driving assembly to work. The driving assembly drives the telescopic member to slide relative to the fixing member, so that the extending portion extends from the fixing member, and at least a part of the extending portion is located on the movement path of the movable plate, so that the movable plate cannot approach the interface, thereby preventing the movable plate from colliding with the plug-in device inserted into the interface and causing damage to the plug-in device or the interface, to protect the plug-in device and the interface; when the plug-in device is unplugged, the display device controls the driving assembly to work again. The driving assembly drives the telescopic member to slide in the reverse direction relative to the fixing member, so that the extending portion retracts into the fixing member and exits the movement path of the movable plate. At this time, the extending portion does not interfere with the movement of the movable plate relative to the display device; the anti-collision device can recognize the signal of plugging and unplugging the plug-in device through the display device and control the driving assembly to drive the telescopic member to extend and retract, with simple operation and convenient control.

[0007] In one embodiment, the driving assembly includes a driving member and a rotating member connected to the output shaft of the driving member. The driving member is configured to drive the rotating member to rotate relative to the fixing member. One of the rotating member and the telescopic member includes a guiding portion, and the other includes a sliding portion capable of sliding along the guiding portion, so as to drive the telescopic member to reciprocally slide relative to the fixing member by the rotating member.

[0008] With such an arrangement, the size of the driving assembly in the sliding direction of the telescopic member can be reduced, and the overall occupied space of the anti-collision device in the display device can be reduced.

[0009] In one embodiment, the telescopic member further includes a sleeve portion connected to the protruding portion and sleeved outside the rotating member. The guiding portion is disposed on the outer peripheral wall of the rotating member, and the sliding portion is disposed on the inner wall of the sleeve portion.

[0010] With such an arrangement, the sliding direction of the sleeve portion can be restricted, and at the same time, the sizes of the rotating member and the telescopic member in the sliding direction of the telescopic member can also be reduced.

[0011] In one embodiment, the guiding portion includes a spiral rib, and the sliding portion abuts against a side surface of the spiral rib facing away from the protruding portion.

[0012] With such an arrangement, the structure of the spiral rib is simple and convenient for processing.

[0013] In one embodiment, the anti-collision device further includes an elastic member disposed between the telescopic member and the fixing member. At least in the contracted state, the elastic member is compressed.

[0014] With such an arrangement, the protruding portion can always abut against a side surface of the spiral rib facing away from the protruding portion, ensuring that when the driving member drives the rotating member to rotate in the reverse direction of the preset direction, the protruding portion can extend out of the fixing member.

[0015] In one embodiment, the guiding portion further includes an abutting section disposed at one end of the spiral rib close to the protruding portion and capable of abutting against the sliding portion. The guiding portion is provided with a disengaging groove located at one end of the spiral rib away from the protruding portion and capable of disengaging from the sliding portion. Along the sliding direction of the telescopic member, the disengaging groove corresponds to the abutting section.

[0016] With such an arrangement, when the guiding portion rotates to a position where the disengaging groove cooperates with the sliding portion, under the elastic force of the elastic member, the sliding portion disengages from the disengaging groove and slides relative to the fixing member to a position where it abuts against the abutting section, so that the protruding portion extends out of the fixing member.

[0017] In one embodiment, a limiting groove is provided on the spiral rib. In the contracted state, a part of the sliding portion is clamped in the limiting groove.

[0018] With such a setting, the limiting groove can position and limit the contracted state of the telescopic member. When the sliding portion is clamped in the limiting groove, it indicates that the telescopic member is in the contracted state, and at the same time, it can also improve the stability and reliability of the telescopic member in the contracted state.

[0019] In one embodiment, the fixing member is provided with a sliding cavity, a part of the telescopic member is slidably disposed in the sliding cavity, and the outer peripheral wall of a part of the telescopic member is in contact with the inner peripheral wall of the sliding cavity.

[0020] With such a setting, it can limit the sliding direction and sliding range of the telescopic member relative to the fixing member, and improve the stability of the telescopic member in the extended state, contracted state, and during the sliding process relative to the fixing member.

[0021] The present utility model also provides a display device, including: a display device provided with an interface; a movable plate capable of moving relative to the display device; and the anti-collision device as described above.

[0022] In one embodiment, the display device further includes two parallel and spaced-apart slide rails, the movable plate is disposed between the two slide rails and can slide along the slide rails, the display device is disposed at the rear side of the movable plate; the fixing member is disposed on any one of the slide rails, and the extending portion can extend / retract toward the other slide rail.

[0023] With such a setting, the anti-collision device will not be exposed, thereby ensuring the regular appearance of the display device; and the size of the anti-collision device is not affected by the distance between the movable plate and the display device, the number of interfaces, the size of the plug-in device, the border size of the display device, etc., thereby improving the compatibility of the anti-collision device.

[0042] Interfaces for plugging in external USB flash drives, cables and other plug-in devices are usually provided on display devices to achieve data transmission between devices. Some existing display devices are combined with traditional blackboards, and the blackboard can be pushed and pulled relative to the display device. However, during the process of pushing and pulling the blackboard, it is easy to collide with plug-in devices such as USB flash drives inserted in the interface, resulting in damage to the plug-in device or the interface.

[0043] To solve the above problems, as Figures 1 to 11 shown, the present utility model first provides an anti-collision device to prevent damage to the plug-in device or the interface caused by pushing and pulling the blackboard.

[0044] As Figure 1, Figure 2 and Figure 6 As shown in Figure 2 and Figure 6 , specifically, the anti-collision device 100 includes a display device. The display device includes a display unit 200 and a movable plate 300 that can move relative to the display unit 200. The display unit 200 is provided with an interface 201. The anti-collision device 100 includes a fixing member 1, a telescopic member 2, and a driving assembly 3, where: The fixing member 1 is used to be disposed on one side of the interface 201; The telescopic member 2 is disposed on the fixing member 1 and can reciprocally slide relative to the fixing member 1. The telescopic member 2 includes a protruding portion 21 that can protrude or retract from the fixing member 1. In the protruding state, at least part of the protruding portion 21 is located on the movement path of the movable plate 300; The driving assembly 3 is disposed on the fixing member 1. The driving assembly 3 is used to be electrically connected to the display unit 200 and can drive the telescopic member 2 to reciprocally slide relative to the fixing member 1.

[0045] It should be noted that along the movement direction of the movable plate 300, the fixing member 1 is disposed on the side of the interface 201 close to the movable plate 300. For example, as shown in Figure 6 , when the movable plate 300 is located on the side of the interface 201 facing the -X direction and moves close to the interface 201 along the +X direction, the fixing member 1 is disposed on the side of the interface 201 facing the -X direction. When the movable plate 300 is located on the side of the interface 201 facing the +X direction and moves close to the interface 201 along the -X direction, the fixing member 1 is disposed on the side of the interface 201 facing the +X direction. And, the ±X direction can be the horizontal direction shown in the figure, or the vertical direction, or other directions that form an angle with the horizontal direction. Figure 6

[0046] In the anti-collision device 100 provided by the embodiment of the present utility model, when a plug-in device such as an external USB flash drive or a cable is inserted into the interface 201, the display unit 200 recognizes the signal and controls the driving assembly 3 to work. The driving assembly 3 drives the telescopic member 2 to slide relative to the fixing member 1, so that the protruding portion 21 protrudes from the fixing member 1, and at least part of the protruding portion 21 is located on the movement path of the movable plate 300. If the movable plate 300 is controlled to move close to the interface 201 relative to the display unit 200 at this time, the movable plate 300 will first collide with the protruding portion 21, so that the movable plate 300 cannot approach the interface 201, thereby preventing the movable plate 300 from colliding with the plug-in device inserted in the interface 201 and causing damage to the plug-in device or the interface 201, to protect the plug-in device and the interface 201; When the external USB flash drive, cable and other plug-in devices are unplugged, the display unit 200 controls the driving assembly 3 to work again. The driving assembly 3 drives the telescopic member to slide reversely relative to the fixing member 1, so that the protruding portion 21 retracts into the fixing member 1 and exits the movement path of the movable plate 300. At this time, the protruding portion 21 will not interfere with the movement of the movable plate 300 relative to the display unit 200.

[0047] ​The anti-collision device 100 can identify the signal of inserting and unplugging the plug-in device through the display device 200 and control the driving component 3 to drive the telescopic member 2 to expand and contract. It does not require the user to manually press or pull the telescopic member 2, with simple operation and convenient control. Moreover, since the anti-collision device 100 is provided on one side of the interface 201 and is independent of the number of interfaces 201, the size of the plug-in device, etc., the anti-collision device 100 can be compatible with different display devices 200.

[0048] As Figure 2 shown, the driving component 3 includes a driving member 31 and a rotating member 32 connected to the output shaft of the driving member 31. The driving member 31 is used to drive the rotating member 32 to rotate relative to the fixing member 1; one of the rotating member 32 and the telescopic member 2 includes a guiding portion 321, and the other includes a sliding portion 22 that can slide along the guiding portion 321, so as to drive the telescopic member 2 to reciprocate relative to the fixing member 1 through the rotating member 32. The guiding portion 321 and the sliding portion 22 cooperate to convert the rotation of the rotating member 32 relative to the fixing member 1 into the sliding of the telescopic member 2 relative to the fixing member 1, thereby being able to reduce the size of the driving component 3 along the sliding direction of the telescopic member 2 and reduce the occupied space of the entire anti-collision device 100 in the display device. Among them, the driving member 31 can be set as a motor, and the motor is connected to the main board of the display device 200 through a cable to realize the electrical connection between the driving component 3 and the display device 200.

[0049] As Figures 3 to 4 shown, in one embodiment, the telescopic member 2 further includes a sleeve portion 23 connected to the protruding portion 21 and sleeved outside the rotating member 32. The guiding portion 321 is provided on the outer peripheral wall of the rotating member 32, and the sliding portion 22 is provided on the inner wall of the sleeve portion 23. The sleeve portion 23 sleeved outside the rotating member 32 can limit the sliding direction of the sleeve portion 23, and at the same time can also reduce the size of the rotating member 32 and the telescopic member 2 along the sliding direction of the telescopic member 2.

[0050] Of course, in other embodiments, it may also be that the guiding portion 321 is provided on the inner peripheral wall of the sleeve portion 23, and the sliding portion 22 is provided on the outer wall of the rotating member 32; it may also be that the rotating member 32 is provided with a sleeve structure and sleeved outside the telescopic member 2, the guiding portion 321 is provided on the outer peripheral wall of the telescopic member 2, and the sliding portion 22 is provided on the inner wall of the sleeve structure, or the guiding portion 321 is provided on the inner peripheral wall of the sleeve structure, and the sliding portion 22 is provided on the outer wall of the telescopic member 2, as long as the rotation of the rotating member 32 relative to the fixing member 1 can be converted into the sliding of the telescopic member 2 relative to the fixing member 1, and the embodiments of the present invention do not make specific limitations here.

[0051] As Figures 3 to 6As shown, in one embodiment, the guiding portion 321 includes a spiral rib 3211, and the sliding portion 22 abuts against one side surface of the spiral rib 3211 facing away from the protruding portion 21. The structure of the spiral rib 3211 is simple and convenient for processing. When the driving member 31 drives the rotating member 32 to rotate in a preset direction, one side surface of the spiral rib 3211 facing away from the protruding portion 21 will push against the sliding portion 22, causing the protruding portion 21 to retract into the fixing member 1; when the driving member 31 drives the rotating member 32 to rotate in the reverse direction of the preset direction, the protruding portion 21 will slide along with one side surface of the spiral rib 3211 facing away, causing the protruding portion 21 to protrude from the fixing member 1.

[0052] Of course, in other embodiments, the guiding portion 321 can also be other structures such as a spiral groove or a spiral slide rail, and the sliding portion 22 is a slider slidably disposed in the guiding portion 321.

[0053] As Figures 3 to 4 shown, the anti-collision device 100 further includes an elastic member 4 disposed between the telescopic member 2 and the fixing member 1, and at least in the retracted state, the elastic member 4 is compressed. The elastic member 4 enables the protruding portion 21 to always abut against one side surface of the spiral rib 3211 facing away from the protruding portion 21, ensuring that when the driving member 31 drives the rotating member 32 to rotate in the reverse direction of the preset direction, the protruding portion 21 can protrude from the fixing member 1. And in the protruding state, the elastic member 4 can also be in a compressed state to improve the stability and reliability of the telescopic member 2 in the protruding state. Among them, the elastic member 4 can be set as an elastic element such as a spring, a disc spring, a spring sheet, or a silicone rubber member.

[0054] Furthermore, the driving member 31 can also drive the rotating member 32 to always rotate in the same direction. The guiding portion 321 further includes an abutting section 3212 disposed at one end of the spiral rib 3211 close to the protruding portion 21 and capable of abutting against the sliding portion 22; the guiding portion 321 is provided with a disengaging groove 3213 located at one end of the spiral rib 3211 away from the protruding portion 21 and capable of disengaging from the sliding portion 22. Along the sliding direction of the telescopic member 2, the disengaging groove 3213 corresponds to the abutting section 3212. Herein, the correspondence between the disengaging groove 3213 and the abutting section 3212 means that the projection of the disengaging groove 3213 on the abutting section 3212 coincides with the abutting section 3212. When the driving member 31 drives the rotating member 32 to rotate in the preset direction, one side surface of the spiral rib 3211 facing away from the protruding portion 21 will push against the sliding portion 22, causing the protruding portion 21 to retract into the fixing member 1; when the guiding portion 321 rotates to the position where the disengaging groove 3213 cooperates with the sliding portion 22, under the action of the elastic force of the elastic member 4, the sliding portion 22 disengages from the disengaging groove 3213 and slides relative to the fixing member 1 to the position where it abuts against the abutting section 3212, causing the protruding portion 21 to protrude from the fixing member 1; the driving member 31 can drive the rotating member 32 to rotate in the preset direction again so that one side surface of the spiral rib 3211 facing away from the protruding portion 21 will push against the sliding portion 22, and the protruding portion 21 retracts into the fixing member 1.

[0055] Among them, the number of the guiding portions 321 can be one, two or more, and the number of the sliding portions 22 is less than or equal to the number of the guiding portions 321. When there are two or more guiding portions 321, the multiple guiding portions 321 are arranged at intervals along the circumferential direction of the rotating member 32, and along the sliding direction of the telescopic member 2, the disengaging groove 3213 of one of the guiding portions 321 corresponds to the abutting section 3212 of the adjacent guiding portion 321. After the sliding portion 22 disengages from the disengaging groove 3213 of one of the guiding portions 321, it will abut against the abutting section 3212 of the adjacent guiding portion 321 and continue to slide along the spiral rib 3211 of the adjacent guiding portion 321.

[0056] As Figures 4 to 6 shown, a limiting groove 3214 is provided on the spiral rib 3211. In the contracted state, a part of the sliding portion 22 is clamped in the limiting groove 3214. The limiting groove 3214 can position and limit the contracted state of the telescopic member 2. When it is necessary to drive the extending portion 21 to retract into the fixing member 1, the driving member 31 drives the rotating member 32 to rotate in a preset direction, so that the extending portion 21 gradually retracts into the fixing member 1. When the sliding portion 22 is clamped in the limiting groove 3214, it means that the telescopic member 2 is in the contracted state, and the driving member 31 stops, preventing the rotating member 32 from rotating to the position where the disengaging groove 3213 cooperates with the sliding portion 22 and causing the telescopic member 2 to accidentally extend. At the same time, it can also improve the stability and reliability of the telescopic member 2 in the contracted state; when it is necessary to drive the extending portion 21 to extend out of the fixing member 1, the driving member 31 drives the rotating member 32 to rotate in a preset direction, so that the extending portion 21 first retracts into the fixing member 1. When the rotating member 32 rotates to the position where the disengaging groove 3213 cooperates with the sliding portion 22, the sliding portion 22 disengages from the disengaging groove 3213 and slides relative to the fixing member 1 to the position where it abuts against the abutting section 3212, so that the extending portion 21 extends out of the fixing member 1.

[0057] As Figures 3 to 4 shown, the fixing member 1 is provided with a sliding cavity 11, and a part of the telescopic member 2 is slidably arranged in the sliding cavity 11, and the outer peripheral wall of a part of the telescopic member 2 is attached to the inner peripheral wall of the sliding cavity 11. The sliding cavity 11 can limit the sliding direction and sliding range of the telescopic member 2 relative to the fixing member 1, and improve the stability of the telescopic member 2 in the extended state, contracted state and during the sliding process relative to the fixing member 1. Specifically, the outer peripheral wall of the sleeve portion 23 can be attached to the inner peripheral wall of the sliding cavity 11. When the telescopic member 2 is in the extended state, the end of the sleeve portion 23 facing the extending portion 21 is attached to the end wall of the sliding cavity 11 to prevent the telescopic member 2 from disengaging from the fixing member 1. The two ends of the elastic member 4 respectively abut against the end of the sleeve portion 23 away from the extending portion 21 and the end wall of the sliding cavity 11.

[0058] As Figure 7As shown in the figure, an embodiment of the present utility model further provides a display device, which includes a display device 200, a movable plate 300, and the above-mentioned anti-collision device 100, where: The display device 200 is provided with an interface 201, and the movable plate 300 can move relative to the display device 200. In the illustrated embodiment, the movable plate 300 can slide away from the display device 200 along the -X direction and slide close to the display device 200 along the +X direction. The anti-collision device 100 is disposed on the side of the interface 201 facing the -X direction. In the extended state, the telescopic member 2 can limit the movable plate 300 from sliding close to the interface 201 along the +X direction. In other embodiments, the anti-collision device 100 can be disposed at other positions of the interface 201 according to the actual movement direction of the movable plate 300, as long as the telescopic member 2 can limit the movable plate 300 from sliding close to the interface 201 in the extended state. The embodiments of the present utility model do not make specific limitations here.

[0059] Among them, when the distance between multiple interfaces 201 is small, it can be that all interfaces 201 share one anti-collision device 100; or, when the distance between multiple interfaces 201 is large, it can also be that each, two or multiple interfaces 201 correspond to one anti-collision device 100, as long as it is ensured that the plug-in device plugged into any interface 201 will not be hit by the movable plate 300.

[0060] As shown in FIGS. 8 to Figure 11 As shown in the figure, the display device further includes two parallel and spaced-apart slide rails 400. The movable plate 300 is disposed between the two slide rails 400 and can slide along the slide rails 400. The display device 200 is disposed behind the movable plate 300; The fixing member 1 is disposed on any one of the slide rails 400, and the extending portion 21 can extend or retract toward the other slide rail 400. Specifically, as Figure 11 As shown in the figure, when the extending portion 21 extends toward the other slide rail 400, it will block the movable plate 300 from moving toward the interface 201; as Figure 10 As shown in the figure, after the extending portion 21 retracts, it will not interfere with the movable plate 300. Since the anti-collision device 100 is disposed on the slide rail 400 and the extending portion 21 extends toward the other slide rail 400, the anti-collision device 100 will not be exposed, thereby ensuring the regular appearance of the display device. Moreover, by disposing the anti-collision device 100 on the slide rail 400, the size of the anti-collision device 100 is not affected by the distance between the movable plate 300 and the display device 200, the number of interfaces 201, the size of the plug-in device, the frame size of the display device 200, etc., thereby further improving the compatibility of the anti-collision device 100.

[0061] Among them, the anti-collision device 100 can be correspondingly disposed on the two slide rails 400 respectively to ensure the reliability of the anti-collision device 100 when blocking the movable plate 300 from moving toward the interface 201; or, the anti-collision device 100 can also be disposed on any one of the slide rails 400.

[0062] As Figure 7 shown, the display device may further include a fixing plate 500 arranged side by side with the display device 200, and the movable plate 300 can slide along the slide rail 400 on the front side of the display device 200 and the fixing plate 500.

[0063] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described.
