[0052] A portable display device includes a housing and a display panel. In non-operating mode, the display panel is housed within the housing for easy carrying. In operating mode, the display panel extends out of the housing for display purposes. The housing contains multiple locking mechanisms that need to be unlocked and locked to switch the display device between operating and non-operating states. These locking mechanisms are activated by buttons. However, in related technologies, the buttons have limited functionality; each button can only unlock and lock one locking mechanism, leading to cumbersome operation. To address these issues, this application provides a bidirectional mechanical lock and display device, improving the functional versatility of the trigger element.

[0053] This application is described below with reference to the accompanying drawings and specific embodiments:

[0054] Please see Figure 1 This application provides a two-way mechanical lock 10 for a display device, which is applied to the display device 1. The two-way mechanical lock 10 for the display device provided in this application can improve the functional versatility of the trigger 300.

[0055] The display device 1 is roughly a cuboid. For ease of description, the height direction, width direction, and thickness direction are defined respectively. In the usage state of the display device 1, the vertical direction is the height direction. The projection of the display device 1 in the vertical direction is a rectangle, where the direction of the long side is the width direction and the direction of the wide side is the thickness direction.

[0056] Please see Figures 1-3 In this embodiment, the display device 1 includes a housing 20, a display panel 30, and a lifting mechanism 40. The lifting mechanism 40 is disposed within the housing 20, and the display panel 30 is mounted on the lifting mechanism 40. The housing 20 includes an outer shell 21 and a top cover 22. The outer shell 21 has an opening at the top, and the top cover 22 is movably connected to the top of the outer shell 21 and covers the opening. When the display device 1 is in a non-working state, the top cover 22 closes the opening, the lifting mechanism 40 remains stationary, and the display panel 30 is housed within the housing 20. When the display device 1 needs to switch to a working state, the top cover 22 needs to be opened, and the lifting mechanism 40 lifts the display panel 30, causing the display panel 30 to extend outside the housing 20 for display.

[0057] The housing 20 is provided with a first locking part 50 and a second locking part 60. A two-way mechanical lock 10 for the display device is provided in the housing 20 for opening or unlocking the first locking part 50 and the second locking part 60. When the display device 1 is in a non-working state, the two-way mechanical lock 10 locks the first locking part 50 and the second locking part 60. When the display device 1 needs to switch to a working state, the two-way mechanical lock 10 unlocks the first locking part 50 and the second locking part 60.

[0058] Please see Figure 4 and Figure 5 In this embodiment, the first locking part 50 can be disposed on the lifting mechanism 40, and the second locking part 60 can be disposed on the top cover 22. That is, when the display device 1 is in a non-working state, the display device bidirectional mechanical lock 10 needs to lock the first locking part 50 and the second locking part 60, so that the top cover 22 closes the opening, the lifting mechanism 40 is fixed, and the display panel 30 is stably housed in the housing 20. When the display device 1 needs to switch to the working state, the display device bidirectional mechanical lock 10 needs to unlock the first locking part 50 and the second locking part 60, so that the top cover 22 can be opened and the lifting mechanism 40 can drive the display panel 30 to rise.

[0059] Of course, the first locking part 50 and the second locking part 60 can also be provided on other parts of the housing 20 that need to be locked or unlocked, and there is no limitation on this.

[0060] Please see Figure 6 and Figure 7 In this embodiment, the bidirectional mechanical lock 10 of the display device includes a fixed unit 100, a movable unit 200, and a trigger 300. The fixed unit 100 is installed inside the housing 20, the movable unit 200 is movably disposed on the fixed unit 100, the movable unit 200 is lockably and unlockably connected to the first locking part 50, the movable unit 200 is lockably and unlockably connected to the second locking part 60, and the trigger 300 is connected to the movable unit 200 and located outside the housing 20.

[0061] The fixing unit 100 is used to fix it inside the housing 20. The fixing unit 100 is the basic component of the display device bidirectional mechanical lock 10. It is used to provide an installation base for at least other components of the display device bidirectional mechanical lock 10, so that the display device bidirectional mechanical lock 10 can be stably installed inside the housing 20. The fixing unit 100 can be fixedly connected to the side wall of the housing 20 by welding, screwing or other methods.

[0062] The movable unit 200 is movably connected to the fixed unit 100. The movable unit 200 can move relative to the fixed unit 100, and its movement can lock and unlock the first locking part 50 or the second locking part 60. The trigger 300 is connected to the movable unit 200, so operating the trigger 300 can move the movable unit 200 to lock and unlock the first locking part 50 or the second locking part 60. The trigger 300 is located outside the housing 20, making it convenient for the user to operate.

[0063] The movable unit 200 can lock and unlock the first locking part 50 and the second locking part 60 respectively through different movable postures. For example, the movable unit 200 can lock and unlock the first locking part 50 and the second locking part 60 respectively by moving or rotating in different directions. The trigger 300 can be operated as needed to drive the movable unit 200 to move in the corresponding movable posture.

[0064] Since the active unit 200 can be locked and unlocked by both the first locking part 50 and the second locking part 60, the first locking part 50 and the second locking part 60 can be locked and unlocked simply by operating the trigger 300. That is, one trigger 300 can perform two sets of functions, thereby improving the functional diversity of the trigger 300 and the convenience of switching between the working and non-working states of the display device 1.

[0065] Please see Figures 8-10In some embodiments, the active unit 200 includes a first active component 210, a second active component 220, a first locking component 230, and a second locking component 240.

[0066] The first movable component 210 includes a movable support portion 211, a first guide portion 212 disposed on the movable support portion 211, and a second guide portion 213 disposed on the movable support. The first guide portion 212 is movably connected to the fixed unit 100 along a first direction Z. The second movable component 220 is movably connected to the second guide portion 213 along a second direction X. The second movable component 220 is connected to the trigger member 300 or the second movable component 220 and the trigger member 300 are integrally formed.

[0067] The first locking component 230 is connected to the first movable component 210, or the first locking component 230 and the first movable component 210 are integrally formed, and the first locking component 230 is lockably and unlockably connected to the first locking part 50. The second locking component 240 is connected to the second movable component 220, or the second locking component 240 and the second movable component 220 are integrally formed, and the second locking component 240 is lockably and unlockably connected to the second locking part 60.

[0068] The movable support portion 211 is movably connected to the fixed unit 100 along the first direction Z. The first guide portion 212 can move along the first direction Z to drive the first movable component 210 to move along the first direction Z as a whole. The first locking component 230 can be connected to the movable support portion 211 or the first guide portion 212, without limitation.

[0069] The first movable component 210 moves along the first direction Z, which in turn moves the first locking component 230, thereby locking or unlocking the first locking part 50. The direction of movement of the first locking component 230 may be the same as or different from the direction of movement of the first movable component 210. Since the second movable component 220 is connected to the trigger 300 or the second movable component 220 and the trigger 300 are an integral structure, and the second movable component 220 is connected to the first movable component 210, the trigger 300 can also be regarded as connected to the first movable component 210. Operating the trigger 300 can drive the first movable component 210 to move. That is to say, when it is necessary to lock or unlock the first locking part 50, operating the trigger 300 causes the trigger 300 to move along the first direction Z, which in turn drives the first movable component 210 to move along the first direction Z.

[0070] The second movable component 220 moves along the second direction X, which in turn drives the second locking component 240 to move, thereby locking or unlocking the second locking part 60. The direction of movement of the second locking component 240 may be the same as or different from the direction of movement of the second movable component 220. That is, when it is necessary to lock or unlock the second locking part 60, the trigger 300 is operated, causing the trigger 300 to move along the second direction X, which in turn drives the second movable component 220 to move along the second direction X.

[0071] Optionally, please refer to Figure 13 The movable support portion 211 includes a first movable plate 211a disposed along a first direction Z and a second movable plate 211b disposed along a second direction X. The first movable plate 211a is movably connected to the fixed unit 100. A second guide portion 213 is disposed on the first movable plate 211a and disposed along the second direction X. The second movable plate 211b is connected to the first guide portion 212, which is disposed along the first direction Z. Furthermore, to improve the structural strength of the movable support portion 211, the movable support portion 211 also includes two side plates 211c, which are disposed on both sides of the first movable plate 211a and connected to the second movable plate 211b.

[0072] Optionally, the first direction Z can be the height direction, where the first movable component 210 moves downward and the first locking component 230 locks the first locking part 50, and the first movable component 210 moves upward and the first locking component 230 unlocks the first locking part 50, or vice versa; the second direction X can be the thickness direction, where the second movable component 220 moves to the right and the second locking component 240 locks the second locking part 60, and the second movable component 220 moves to the left and the second locking component 240 unlocks the second locking part 60, or vice versa.

[0073] The trigger 300 can perform different functions by moving in different directions, which improves the functional versatility of the trigger 300 and makes the unlocking and locking operations of the first locking part 50 and the second locking part 60 more convenient.

[0074] In some embodiments, the first guide portion 212 is movably connected to the fixed unit 100 by a guide rail connection or a guide rod connection, and the second guide portion 213 is movably connected to the second movable component 220 by a guide rail connection or a guide rod connection.

[0075] The movable connection between the first guide part 212 and the fixed unit 100 can be a guide rail connection. That is, one of the first guide part 212 and the fixed unit 100 is provided with a slide rail, and the other is provided with a slider. The slider slides and engages with the slide rail along the first direction Z, thereby providing guidance for the movement of the first guide part 212.

[0076] The movable connection between the first guide portion 212 and the fixing unit 100 can also be a guide rod connection. Optionally, the first guide portion 212 is rod-shaped, and the fixing unit 100 is provided with a first guide hole 110, through which the first guide portion 212 movably passes along the first direction Z. Alternatively, the first guide portion 212 is provided with a first guide hole 110, and the fixing unit 100 has a rod-shaped structure that mates with the first guide hole 110 along the first direction Z. The mating of the rod and the hole can provide guidance for the movement of the first guide portion 212, and this is not limited.

[0077] Similarly, the movable connection between the second guide portion 213 and the second movable component 220 can be a guide rail connection, that is, one of the second guide portion 213 and the second movable component 220 is provided with a slide rail, and the other is provided with a slider. The slider slides and engages with the slide rail along the second direction X, thereby providing guidance for the movement of the second guide portion 213.

[0078] The movable connection between the second guide portion 213 and the second movable component 220 can also be a guide rod connection. Optionally, the second guide portion 213 is rod-shaped, and the second movable component 220 is provided with a second guide hole 221, through which the second guide portion 213 movably passes along the second direction X. Alternatively, the second guide portion 213 is provided with a second guide hole 221, and the second movable component 220 has a rod-shaped structure that mates with the second guide hole 221 along the second direction X. The mating of the rod and the hole can provide guidance for the movement of the second guide portion 213, and this is not limited.

[0079] Of course, the movable connection between the movable support part 211 and the fixed unit 100 can also be a guide rail connection or a guide rod connection. The movable connection between the movable support part 211 and the fixed unit 100 can be referred to the movable connection between the first guide part 212 and the fixed unit 100 and the movable connection between the second guide part 213 and the second movable component 220, as described above, and will not be repeated here.

[0080] Please see Figures 6-8 In some embodiments, the trigger 300 includes a key body 310 and a keycap 320 fitted onto the key body 310. The second movable component 220 is connected to the key body 310 or the second movable component 220 and the key body 310 are an integral structure. The key body 310 needs to be movably inserted into the housing 20 so that the trigger 300 is located outside the housing 20.

[0081] Since the second locking component 240 is used to unlock and lock the second locking part 60, which is located on the top cover 22, the second locking component 240 needs to be located close to the top cover 22 to facilitate its cooperation with the second locking part 60. Since the second locking component 240 is connected to the second movable component 220, the second movable component 220 and the trigger 300 can also be located close to the top cover 22 to facilitate the movement of the second locking component 240. Optionally, the fixing unit 100, the first movable component 210, the second movable component 220, and the second locking component 240 can all be arranged on the side wall of the housing 20 near the top cover 22, with the button body 310 passing through the top cover 22 and the trigger 300 located on the outside of the top cover 22.

[0082] A mounting groove 23 can be provided on the top cover 22, and the trigger 300 is located in the mounting groove 23. Thus, the mounting groove 23 can protect the trigger 300 and try to avoid the trigger 300 being bumped, which could cause the first locking part 50 or the second locking part 60 to be accidentally locked or unlocked.

[0083] Please see Figure 9 In some embodiments, the movable unit 200 further includes a first elastic member 250, which is sleeved on the first guide portion 212, and its two ends abut against the movable support portion 211 and the fixing unit 100, respectively; or,

[0084] The movable unit 200 also includes a first elastic element 250 and a connecting rod 260. The fixed unit 100 is provided with a connecting hole 120. The connecting rod 260 is connected to the movable support part 211. The connecting rod 260 is movably inserted through the connecting hole 120 along the first direction Z. The first elastic element 250 is sleeved on the connecting rod 260. The two ends of the first elastic element 250 abut against the movable support part 211 and the fixed unit 100, respectively.

[0085] When the trigger 300 is operated to unlock the first locking part 50 of the first locking component 230, the moving unit 200 further includes a first elastic element 250 to automatically reset the trigger 300 in preparation for the next unlocking. The first elastic element 250 is used to automatically reset the trigger 300. Therefore, the trigger 300 only needs to be operated when the first locking part 50 needs to be unlocked, and the trigger 300 will automatically reset after unlocking, thereby further improving operational convenience. Optionally, the first elastic element 250 can be a spring.

[0086] The first guide portion 212 and the fixed unit 100 can be connected by a guide rod, that is, the first guide portion 212 is rod-shaped, the fixed unit 100 is provided with a first guide hole 110, and the first guide portion 212 is movably inserted through the first guide hole 110 along the first direction Z.

[0087] There are two ways to set the first elastic element 250. The first way is that the first elastic element 250 is directly sleeved on the first guide part 212, and the two ends of the first elastic element 250 abut against the movable bracket part 211 and the fixed unit 100 respectively. In this way, when the user operates the trigger 300 to make the first movable component 210 move along the first direction Z to unlock the first locking part 50, the distance between the movable bracket part 211 and the fixed unit 100 is shortened, and the first elastic element 250 is compressed. When the user releases the trigger 300, the first elastic element 250 is released elastically. Under the action of the elastic force, the first elastic element 250 will push the movable bracket part 211 to reset, thereby driving the trigger 300 to reset.

[0088] The second method involves a first elastic element 250 sleeved on a connecting rod 260. Both ends of the first elastic element 250 abut against the movable support portion 211 and the fixed unit 100, respectively. In this second method, the reset principle of the first elastic element 250 is the same as in the first method, and will not be repeated here. The connecting rod 260 can also be considered a guide element. Optionally, two connecting rods 260 can be provided, with the two connecting rods 260 respectively located on both sides of the first guide portion 212.

[0089] Of course, in order to prevent the connecting rod 260 from disengaging from the connecting hole 120 when the first elastic element 250 is released elastically, a first limiting part 261 may be provided at the end of the connecting rod 260 away from the movable bracket part 211.

[0090] It should be noted that the two ends of the first elastic member 250 abut against the movable support portion 211 and the fixed unit 100 respectively. That is, the two ends of the first elastic member 250 can be connected to the movable support portion 211 and the fixed unit 100 respectively, or the two ends of the first elastic member 250 can be not connected to the movable support portion 211 and the fixed unit 100. It is only necessary to ensure that the two ends of the first elastic member 250 are in contact with the movable support portion 211 and the fixed unit 100 respectively.

[0091] Optionally, please refer to Figure 13 The fixing unit 100 has a first fixing plate 130 arranged along the first direction Z and a second fixing plate 140 arranged along the second direction X. The first fixing plate 130 is used to be installed on the housing 20, and the second fixing plate 140 is used to provide a first guide hole 110 and connect the first elastic member 250.

[0092] Please see Figure 8 and Figure 9 In some embodiments, the movable unit 200 includes a connecting lever 270, the fulcrum of which is rotatably connected to the fixed unit 100, one end of the connecting lever 270 is hinged to the first movable component 210, and the other end of the connecting lever 270 is connected to the first locking component 230.

[0093] The hinge point between the connecting lever 270 and the first movable component 210, and the connection point between the connecting lever 270 and the first locking component 230, are located on opposite sides of the fulcrum. Since the fulcrum of the connecting lever 270 is rotatably connected to the fixed unit 100, according to the lever principle, when the first movable component 210 moves downward, the other part of the connecting lever 270 will move upward, thereby causing the first locking component 230 to unlock the first locking part 50.

[0094] Optionally, one part of the connecting lever 270 is hinged to the first guide portion 212, and one part of the connecting lever 270 is provided with a pin hole 271, which is an elongated hole. The lower end of the first guide portion 212 has a pin 214, which passes through the pin hole 271. During the movement of the first movable component 210, the pin 214 can move within the pin hole 271, so that the connecting lever 270 can rotate.

[0095] Please see Figure 8 In some embodiments, the movable unit 200 further includes a reversing connector 280, which is connected to the connecting lever 270. The first locking assembly 230 includes a locking bracket portion 231 and a locking pin 232 movably disposed on the locking bracket portion 231. The first locking portion 50 has a locking port 51, and the locking pin 232 is detachably disposed in the locking port 51 and connected to the reversing connector 280.

[0096] The first locking part 50 can be disposed at the bottom of the lifting mechanism 40, and the first locking component 230 can be disposed at the bottom of the housing 20, corresponding to the first locking part 50. Since the first movable component 210 is disposed near the top cover 22, the connecting lever 270 needs to be connected to the locking pin 232 through the reversing connector 280.

[0097] The locking pin 232 passes through the locking port 51, thus locking the first locking part. The locking pin 232 moves away from the locking port 51 until it separates from the locking port 51, thus unlocking the first locking part. The connecting lever 270 is connected to the locking pin 232 via the reversing connector 280. Since the locking pin 232 is movably mounted on the locking bracket part 231, the movement of the connecting lever 270, through the reversing connector 280, drives the locking pin 232 to move, causing the locking pin 232 to pass through or separate from the locking port 51.

[0098] Please see Figure 11 In some embodiments, the first locking component 230 includes a third elastic member 233, the two ends of which abut against the locking pin 232 and the locking bracket portion 231 respectively, so that the locking pin 232 moves toward the locking port 51.

[0099] After the locking pin 232 is separated from the locking port 51 and unlocking is achieved, in order to reset the locking pin 232 and prepare for the next insertion of the locking pin 232 into the locking port 51, the first locking component 230 includes a third elastic member 233. Since the two ends of the third elastic member 233 abut against the locking pin 232 and the locking bracket portion 231 respectively, when the first locking component 230 moves the locking pin 232 away from the locking port 51 to separate the locking pin 232 from the locking port 51, the third elastic member 233 will be compressed. After unlocking is completed, the third elastic member 233 is released elastically, which can move the locking pin 232 towards the locking port 51 to achieve reset.

[0100] Of course, the two ends of the third elastic element 233 may be connected to the locking pin 232 and the locking bracket part 231 respectively, or they may not be connected to the locking pin 232 and the locking bracket part 231. There is no restriction on this.

[0101] Optionally, the first locking assembly 230 includes a guide rod 234 connected to the locking pin 232, a guide portion movably disposed on the locking bracket portion 231, a reversing connector 280 connected to the guide portion, and a third elastic member 233 sleeved on the guide rod 234. The third elastic member 233 can be a spring.

[0102] Please see Figure 4 In some embodiments, the first locking part 50 may be movable relative to the first locking assembly 230, so that the first locking part 50 has a locked state and an active state. The locking pin 232 has a first inclined surface 232a, which is located in the direction of the locking pin 232 toward the first locking part 50 when it is in the active state; and / or, the first locking part 50 has a second inclined surface 52, which is located in the direction of the first locking part 50 toward the locking pin 232 when it is in the active state.

[0103] When the locking pin 232 is inserted into the locking slot 51, the first locking part 50 is locked. At this time, the first locking part 50 is in a locked state. When the locking pin 232 is separated from the locking slot 51, the first locking part 50 is unlocked. At this time, the first locking part 50 can move relative to the first locking component 230 and is in an active state. After the locking pin 232 is separated from the locking slot 51, under the action of the third elastic member 233, the locking pin 232 will reset, that is, the locking pin 232 will return to the original position of locking the locking slot 51. When the first locking part 50 needs to be locked again, the locking pin 232 and the first locking part 50 need to cooperate so that the locking pin 232 can retract and automatically insert into the locking slot 51.

[0104] Since the first locking part 50 is provided on the lifting mechanism 40, the first locking part 50 is in an active state when the lifting mechanism 40 is raised or lowered, and in a locked state when the lifting mechanism 40 is housed in the housing 20. During the process of the first locking part 50 changing from the active state to the locked state, the first locking part 50 will move towards the first locking component 230 so that the first locking component 230 locks the first locking part 50.

[0105] Optionally, the locking pin 232 may have a first inclined surface 232a, which is located in the direction when the locking pin 232 is in the active state toward the first locking part 50. In this way, when the first locking part 50 moves toward the first locking assembly 230, the first locking part 50 will contact the first inclined surface 232a. Since the locking pin 232 is retractable under the action of the third elastic member 233, the first locking part 50 can move relative to the first inclined surface 232a and drive the locking pin 232 to retract. Thus, the first locking part 50 can continue to move through the locking pin 232 until the first locking part 50 leaves the first inclined surface 232a. At this time, the locking port 51 is correspondingly set with the locking pin 232, and the locking pin 232 is reset under the action of the third elastic member 233 and inserted into the locking port 51 to achieve automatic locking.

[0106] Optionally, the first locking part 50 may have a second inclined surface 52. The second inclined surface 52 is located in the direction facing the locking pin 232 when the first locking part 50 is in the active state. In this way, when the first locking part 50 changes from the active state to the locked state, that is, when the first locking part 50 moves towards the first locking component 230, the second inclined surface 52 will contact the locking pin 232. Therefore, the second inclined surface 52 can lock the movement of the locking pin 232 and drive the locking pin 232 to retract. Thus, the first locking part 50 can continue to move through the locking pin 232 until the second inclined surface 52 leaves the locking pin 232. At this time, the locking port 51 is correspondingly set with the locking pin 232. The locking pin 232 is reset under the action of the third elastic member 233 and inserted into the locking port 51 to achieve automatic locking.

[0107] Alternatively, the locking pin 232 can have a first inclined surface 232a, which is located in the direction of the locking pin 232 towards the first locking part 50 when it is in the active state. The first locking part 50 can have a second inclined surface 52, which is located in the direction of the first locking part 50 towards the locking pin 232 when it is in the active state. In this way, when the first locking part 50 moves towards the first locking assembly 230, the first inclined surface 232a will contact the second inclined surface 52 and move relative to it, causing the locking pin 232 to retract. Thus, the first locking part 50 can continue to move through the locking pin 232 until the second inclined surface 52 leaves the first inclined surface 232a. At this time, the locking port 51 is correspondingly set with the locking pin 232. The locking pin 232 is reset under the action of the third elastic member 233 and inserted into the locking port 51 to achieve automatic locking.

[0108] All three schemes can achieve automatic retraction of the locking pin 232 and insertion into the locking slot 51. Any of the three schemes can be used, and there is no restriction on which one is adopted.

[0109] Please see Figure 11 In some embodiments, the first locking component 230 is lockably and unlockably connected to the first locking part 50 in a third direction Y, which is different from the first direction Z; the reversing connector 280 includes a traction rope 281 and a reversing part 282, one end of the traction rope 281 is connected to the connecting lever 270, and the other end of the traction rope 281 is wound around the reversing part 282 and connected to the locking pin 232.

[0110] Since the third direction Y is different from the first direction Z, the connection between the connecting lever 270 and the locking pin 232 needs to be reversed so that the first movable component 210 can move in the first direction Z and drive the first locking component 230 to move in the third direction Y. Since the reversing connector 280 includes a traction rope 281 and a reversing part 282, one end of the traction rope 281 is connected to the connecting lever 270, and the other end of the traction rope 281 is wound around the reversing part 282 and connected to the locking pin 232. That is, the traction rope 281 is reversed in the process of being wound around the reversing part 282. Thus, the first movable component 210 can move in the first direction Z and drive part of the traction rope 281 to move in the third direction Y, thereby driving the locking pin 232 to move in the third direction Y.

[0111] Optionally, the third direction Y can be the thickness direction, and the reversing part 282 includes a reversing wheel, with the traction rope 281 wound around the reversing wheel.

[0112] Please see Figure 9 In some embodiments, the movable unit 200 further includes a second elastic member 290, which is sleeved on the second guide portion 213, and the two ends of the second elastic member 290 abut against the movable support portion 211 and the second movable component 220, respectively.

[0113] When the trigger 300 is operated to unlock the second locking part 60 of the second locking component 240, the moving unit 200 also includes a second elastic element 290 to automatically reset the trigger 300 in preparation for the next unlocking. The second elastic element is used to automatically reset the trigger 300. Therefore, the trigger 300 only needs to be operated when the second locking part 60 needs to be unlocked; after unlocking, the trigger 300 will automatically reset, further improving operational convenience. Optionally, the second elastic element 290 can be a spring.

[0114] The second guide portion 213 and the second movable component 220 can be connected by a guide rod, that is, the second guide portion 213 is rod-shaped, the second movable component 220 is provided with a second guide hole 221, the second guide portion 213 passes through the second guide hole 221 along the second direction X, and the second guide portion 213 and the second guide hole 221 are movably engaged.

[0115] The second elastic member 290 can be sleeved on the second guide portion 213, and the two ends of the second elastic member 290 abut against the movable bracket portion 211 and the second movable component 220 respectively. In this way, when the user operates the trigger member 300 to move the second movable component 220 along the second direction X to unlock the second locking portion 60, the distance between the movable bracket portion 211 and the second movable component 220 is shortened, and the second elastic member 290 is compressed. When the user releases the trigger member 300, the second elastic member 290 is elastically released, which will push the second movable component 220 to reset, thereby driving the trigger member 300 to reset.

[0116] Of course, in order to prevent the second guide hole 221 from disengaging from the second guide portion 213 when the second elastic member 290 is released elastically, a second limiting portion 213a may be provided at the end of the second guide portion 213 away from the movable support portion 211.

[0117] It should be noted that the two ends of the second elastic member 290 abut against the movable support portion 211 and the second movable component 220 respectively. That is, the two ends of the second elastic member 290 can be connected to the movable support portion 211 and the second movable component 220 respectively, or the two ends of the second elastic member 290 can be not connected to the movable support portion 211 and the second movable component 220. It is only necessary to ensure that the two ends of the second elastic member 290 are in contact with the movable support portion 211 and the second movable component 220 respectively.

[0118] Please see Figure 12 In some embodiments, the second locking component 240 has a hook 241 and the second locking part 60 has a slot 61, the hook 241 being detachably engaged with the slot 61.

[0119] The hook 241 engages with the slot 61, thus locking the second locking part. Moving the hook 241 away from the slot 61 until it separates from the slot 61 unlocks the second locking part. Because the hook 241 is engaged within the slot 61, it does not protrude from the top cover 22, thus ensuring the aesthetic appearance of the housing 20. The number of hooks 241 and slots 61 can be one, two, or more; there is no limitation on this.

[0120] Of course, in other embodiments, the hook 241 can also be directly snapped onto the top cover 22 to fix the top cover 22, and there is no limitation on this.

[0121] In some embodiments, the second locking part 60 may be movable relative to the second locking component 240, so that the second locking part 60 has a locked state and an active state; the hook 241 has a third inclined surface 241a, the third inclined surface 241a being located in the direction of the hook 241 toward the second locking part 60 when it is in the active state; and / or, the second locking part 60 has a fourth inclined surface 62, the fourth inclined surface 62 being located in the direction of the second locking part 60 toward the hook 241 when it is in the active state.

[0122] When the hook 241 is inserted into the slot 61, the second locking part 60 is locked. At this time, the second locking part 60 is in a locked state. When the hook 241 is separated from the slot 61, the second locking part 60 is unlocked, and the second locking part 60 can move relative to the first locking component 230, and is in an active state. After the hook 241 is separated from the slot 61, under the action of the second elastic member 290, the hook 241 will reset, that is, the hook 241 will return to its original position of locking the slot 61. When the second locking part 60 needs to be locked again, the hook 241 and the second locking part 60 need to cooperate so that the hook 241 can retract and automatically insert into the slot 61.

[0123] Since the second locking part 60 is provided on the top cover 22, the second locking part 60 is in an active state when the top cover 22 rotates relative to the outer casing 21, and in a locked state when the top cover 22 closes the opening. During the process of the second locking part 60 changing from the active state to the locked state, the second locking part 60 moves towards the second locking assembly 240 so that the second locking assembly 240 locks the second locking part 60.

[0124] Optionally, the hook 241 may have a third inclined surface 241a, which is located in the direction when the hook 241 is in the active state toward the second locking part 60. In this way, when the second locking part 60 moves toward the first locking component 230, the second locking part 60 will contact the third inclined surface 241a. Since the hook 241 is retractable under the action of the second elastic member 290, the second locking part 60 can move relative to the third inclined surface 241a and drive the hook 241 to retract. Thus, the second locking part 60 can continue to move through the hook 241 until the second locking part 60 leaves the third inclined surface 241a. At this time, the slot 61 is correspondingly set with the hook 241, and the hook 241 is reset under the action of the second elastic member 290 and inserted into the slot 61 to achieve automatic locking.

[0125] Furthermore, the second locking part 60 may have a fourth inclined surface 62. The fourth inclined surface 62 is located in the direction facing the hook 241 when the second locking part 60 is in the active state. In this way, when the second locking part 60 changes from the active state to the locked state, that is, when the second locking part 60 moves towards the first locking component 230, the fourth inclined surface 62 will contact the hook 241. Therefore, the fourth inclined surface 62 can move the hook 241 and drive the hook 241 to retract. Thus, the second locking part 60 can continue to move through the hook 241 until the fourth inclined surface 62 leaves the hook 241. At this time, the slot 61 is correspondingly set with the hook 241. The hook 241 is reset under the action of the second elastic member 290 and inserted into the slot 61 to achieve automatic locking.

[0126] Alternatively, the hook 241 can have a third inclined surface 241a, which is located in the direction when the hook 241 is in the active state toward the second locking part 60. The second locking part 60 can have a fourth inclined surface 62, which is located in the direction when the second locking part 60 is in the active state toward the hook 241. In this way, when the second locking part 60 moves toward the first locking component 230, the third inclined surface 241a will contact and move relative to the fourth inclined surface 62, causing the hook 241 to retract. Thus, the second locking part 60 can continue to move through the hook 241 until the fourth inclined surface 62 leaves the third inclined surface 241a. At this time, the slot 61 and the hook 241 are correspondingly set. The hook 241 is reset under the action of the second elastic member 290 and inserted into the slot 61 to achieve automatic locking.

[0127] All three of the above solutions can achieve automatic retraction of the hook 241 and insertion into the slot 61. Any solution can be used, and there is no limitation on this.

[0128] Based on the same inventive concept, please refer to Figures 1-3This application provides a display device 1, including a housing 20, a display panel 30, and a bidirectional mechanical lock 10 for the display device. The display panel 30 is installed inside the housing 20. The beneficial effects of the display device 1 provided in this application are the same as those of the bidirectional mechanical lock 10 for the display device described above, and will not be repeated here.

[0129] Display panel 30 is used to display information. Optionally, display panel 30 may be an OLED (Organic Light-Emitting Diode) display panel.

[0130] Please see Figure 4 In some embodiments, the display device 1 includes a lifting mechanism 40, which is disposed inside the housing 20, the display panel 30 is mounted on the lifting mechanism 40, and the first locking part 50 is disposed on the lifting mechanism 40.

[0131] The lifting mechanism 40 is vertically mounted within the housing 20 to move the display panel 30 up and down. When the display device 1 is not in operation, the two-way mechanical lock 10 locks the first locking part 50, fixing the lifting mechanism 40 in place and stably housing the display panel 30 within the housing 20. When the display device 1 needs to be switched to the operating state, the two-way mechanical lock 10 unlocks the first locking part 50, allowing the lifting mechanism 40 to raise the display panel 30. Of course, after the display panel 30 is no longer in use, the lifting mechanism 40 will descend to reposition the display panel 30 back into the housing 20.

[0132] Please see Figure 5 In some embodiments, the housing 20 includes an outer shell 21 and a top cover 22, the outer shell 21 having a top opening, the top cover 22 being movably connected to the top of the outer shell 21 and covering the opening, and a second locking part 60 being disposed on the top cover 22.

[0133] The top cover 22 is hinged to the top of the housing 21 to open or close the opening. When the display device 1 is in a non-operating state, the display panel 30 is housed in the housing 20, and the two-way mechanical lock 10 of the display device needs to lock the second locking part 60 to close the opening of the top cover 22. When the display device 1 needs to switch to the operating state, the two-way mechanical lock 10 of the display device needs to unlock the second locking part 60 to allow the top cover 22 to open, so that the lifting mechanism 40 can drive the display panel 30 to rise.
