[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] A first aspect of the present invention provides a lifting structure. For example... Figure 1 As shown, the lifting structure includes: a lifting guide shaft 1; a lifting housing 2, which is sleeved on the lifting guide shaft 1 and can slide along the lifting guide shaft 1; and a lifting locking assembly 3. The lifting locking assembly 3 has a locked state and an unlocked state. In the locked state, the lifting locking assembly 3 cooperates with the lifting guide shaft 1 to lock the lifting housing 2 onto the lifting guide shaft 1, restricting the movement of the lifting housing 2 relative to the lifting guide shaft 1. In the unlocked state, the lifting locking assembly 3 releases the lock between the lifting housing 2 and the lifting guide shaft 1, allowing the lifting housing 2 to move relative to the lifting guide shaft 1.

[0025] like Figure 2-6 As shown, the lifting and locking assembly 3 includes: a bottom cover 31, which is connected to the lifting housing 2, and the bottom cover has a bottom cover through hole 311 through which the lifting guide shaft 1 passes; a locking tongue 32, one end of which is hinged to the bottom cover 31, and the locking tongue 32 has a through hole 321 through which the lifting guide shaft 1 passes; and an elastic member 33, which is connected to the locking tongue 32. During the transition from the unlocked state to the locked state, the elastic member applies a spring force to the locking tongue 32 until the lifting guide shaft 1 and the through hole 321 of the locking tongue 32 are rubbed and engaged, thereby locking the lifting housing 2 onto the lifting guide shaft 1.

[0026] In the illustrated embodiment, the lifting locking assembly 3 is provided with two vertically spaced locking tongues 32, namely an upper locking tongue 32A and a lower locking tongue 32B. The upper locking tongue 32A includes a first hinge end 322A hinged to the bottom cover 31 and a first working end 323A opposite to the first hinge end 322A. The lower locking tongue 32B includes a second hinge end 322B hinged to the bottom cover 31 and a second working end 323B opposite to the second hinge end 322B. The first hinge end 322A and the second hinge end 322B are located on the same side. An elastic element 33 is sleeved on the lifting guide shaft 1 and located between the upper locking tongue 32A and the lower locking tongue 32B. In this document, "vertical" refers to the extending direction or axial direction of the lifting guide shaft 1.

[0027] In the illustrated embodiment, the lifting locking assembly 3 further includes a latch support 34, through which the upper latch 32A and the lower latch 32B are mounted on the bottom cover 31. Specifically, the latch support 34 includes an upper mounting portion 34A, a lower mounting portion 34B, and an intermediate mounting portion 34C located between the two. The upper latch 32A is hinged to the upper mounting portion 34A, and the lower latch 32B is hinged to the lower mounting portion 34B. The intermediate mounting portion 34C is used to connect to the bottom cover 31. To achieve the hinged mounting, in the illustrated embodiment, the upper latch 32A and the lower latch 32B each include two arm portions with mounting holes spaced apart from each other. The upper mounting portion 34A and the lower mounting portion 34B each include mounting holes, and the hinged mounting is achieved by passing a pin through these mounting holes. In other embodiments, the upper mounting portion 34A and the lower mounting portion 34B each include two support arms with mounting holes spaced apart from each other, and the upper latch 32A and the lower latch 32B each include mounting holes, with a pin passing through these mounting holes to achieve hinged mounting. To prevent the bottom cover 31 from interfering with the movement of the lower latch 32B, the lower mounting portion 34B of the latch support 34 is spaced a certain distance from the lower surface of the bottom cover 31 to provide sufficient movement space for the lower latch 32B.

[0028] Although two latches 32 are provided in the illustrated embodiment, it should be understood that the lifting locking assembly 3 can also be provided with only one latch 32, which can achieve the same function. In the embodiment with one latch 32, the latch 32 can be hinged to the bottom cover 31, and the elastic element 33 is disposed between the latch 32 and the bottom cover 31. The latch 32 can also be hinged to the bottom cover 31 by a latch support similar to a latch support 34. In this case, the latch 32 can be hinged to either the upper mounting part or the lower mounting part of the latch support.

[0029] In the illustrated embodiment, the lifting locking assembly 3 further includes a latch limiting block 35 disposed between the upper latch 32A and the lower latch 32B, for limiting the movement of the upper latch 32A and the lower latch 32B. Preferably, the latch limiting block 35 is mounted on the middle mounting portion 34C of the latch support 34.

[0030] Figure 3 and Figure 4 The locked state of the lifting locking assembly 3 is shown. In the locked state, the elastic element 33 applies elastic force to the upper locking tongue 32A and the lower locking tongue 32B so that the vertical distance between the first working end 323A and the second working end 323B is greater than the vertical distance between the first hinge end 322A and the second hinge end 322B. That is, the upper locking tongue 32A and the lower locking tongue 32B are not perpendicular to the lifting guide shaft 1, and the lifting guide shaft 1 is frictionally engaged with the through holes of the upper locking tongue 32A and the lower locking tongue 32B.

[0031] Figure 5 and Figure 6 The unlocked state of the lifting locking assembly 3 is shown. In the unlocked state, the elastic element 33 is compressed, and the vertical distance between the first working end 323A and the second working end 323B is equal to the vertical distance between the first hinge end 322A and the second hinge end 322B. That is, the upper locking tongue 32A and the lower locking tongue 32B are parallel to each other and perpendicular to the lifting guide shaft 1. The lifting guide shaft 1 can move freely relative to the through holes of the upper locking tongue 32A and the lower locking tongue 32B.

[0032] In some embodiments, in order to facilitate smooth lifting and lowering without jamming, there is a certain gap between the lifting guide shaft 1 and the through hole of the locking tongue 32, for example, 2-4mm.

[0033] In some embodiments, in order to facilitate smooth lifting and lowering without jamming, an elastic damping element may be provided between the lifting guide shaft 1 and the through hole of the locking tongue 32.

[0034] In some embodiments, to save effort and reduce adjustment difficulty, the lifting structure is further provided with an elastic drive component 4. The elastic drive component 4 is connected between the lifting guide shaft 1 and the bottom cover 31, and is used to drive the lifting housing 2 to slide relative to the lifting guide shaft 1 when the lifting locking component 3 is in the unlocked state.

[0035] In some embodiments, such as Figure 1 and Figure 7As shown, the elastic drive assembly 4 includes: a coil spring 41, a coil spring bracket 42, and a coil spring guide block 43. The coil spring 41 is mounted on the coil spring bracket 42, and the coil spring bracket 42 is fixedly connected to the lifting guide shaft 1. One end of the coil spring 41 extends through the coil spring guide block 43 and is fixedly connected to the bottom cover 31. The coil spring 41 is in a compressed state so that when the lifting locking assembly 3 is in an unlocked state, the compressed coil spring 41 can rebound to drive the lifting housing 2 to slide upward relative to the lifting guide shaft 1.

[0036] In the illustrated embodiment, the coil spring bracket 42 includes a first coil spring bracket 42A and a second coil spring bracket 42B, which cooperate to form an installation space for accommodating the coil spring 41. The coil spring 41 is mounted on the first coil spring bracket 42A and the second coil spring bracket 42B via a pin 44. In the illustrated embodiment, the first coil spring bracket 42A and the second coil spring bracket 42B are fixedly mounted on the lifting guide shaft 1 via a coil spring guide block 43. In the locked state, the coil spring 41 is in a compressed state; in the unlocked state, the compressed coil spring 41 rebounds, causing the lifting housing 2 to slide upward relative to the lifting guide shaft 1.

[0037] In some embodiments, such as Figure 1 and Figure 7 As shown, the lifting structure is also equipped with a lifting limit slider 5 fixedly connected to the lifting guide shaft 1. The lifting limit slider 5 is used to limit the upper limit position of the lifting adjustment. Specifically, the outer diameter of the lifting limit slider 5 is larger than the outer diameter of the lifting guide shaft 1 and larger than the through hole diameter of the upper locking tongue 32A. The upper locking tongue 32A can be engaged below the lifting limit slider 5, and the lifting limit slider 5 prevents the upper locking tongue 32A from moving further upward along the lifting guide shaft 1.

[0038] like Figure 1 As shown, the lifting structure also includes a base 6 that supports the lifting guide shaft 1.

[0039] The lifting structure provided by this invention, by setting a lifting locking component 3, allows the lifting housing 2 to be locked onto the lifting guide shaft 1 by applying a spring force to the locking tongue 32 through the elastic element 33 when height adjustment is not required, thus preventing relative movement between the two. When height adjustment is required, a force is applied to the locking tongue 32 to overcome the spring force of the elastic element 33, causing the locking tongue 32 to no longer rub against the lifting guide shaft 1, thereby releasing the lock between the lifting housing 2 and the lifting guide shaft 1 and allowing the lifting housing 2 to slide relative to the lifting guide shaft 1. The lifting structure provided by this invention uses a sleeve-type engagement method to achieve lifting adjustment, which has the advantages of a large adjustable height range, small space occupation, and flexibility and convenience.

[0040] A second aspect of the present invention provides a display screen support platform. For example... Figure 8As shown, the display support platform includes: a platform housing 100 for receiving the display screen; a lifting structure as described in the first aspect of the present invention, the lifting structure (specifically the lifting housing 2) being connected to the platform housing 100, the lifting structure being used to support the platform housing 100 and to drive the platform housing 100 to rise and fall; and a lifting button 200, the lifting button 200 being mounted on the platform housing 100 and being actuated by a user to move from a first position to a second position to trigger the lifting locking component 3 to unlock.

[0041] In some embodiments, the display support platform further includes a pull cable assembly 300, which is used to trigger the lifting locking assembly 3 to unlock. Specifically, the pull cable assembly 300 acts on the other end (the end opposite to the hinge end) of the locking tongue 32 of the lifting locking assembly 3 to apply a force sufficient to overcome the elasticity, thereby unlocking the lifting locking assembly 3.

[0042] In some embodiments, the display support platform further includes a lifting automatic reset drive assembly 400, wherein the lifting button 200 is connected to the pull cable assembly 300 through the lifting automatic reset drive assembly 400, and the lifting automatic reset drive assembly 400 is used to reset the lifting button 200 and the pull cable assembly 300 after the user releases the lifting button 200.

[0043] In the illustrated embodiment, the pull cord assembly 300 is connected to the first working end 323A of the upper locking tongue 32A and the second working end 323B of the lower locking tongue 32B, for applying a force to overcome the elastic force of the elastic member 33. Specifically, the pull cord assembly 300 includes a wire core 3001 and a sheath 3002 sleeved on the outside of the wire core 3001 and slidable relative to the wire core 3001. The sheath 3002 is connected to the first working end 323A of the upper locking tongue 32A, and the wire core 3001 is connected to the second working end 323B of the lower locking tongue 32B. In the illustrated embodiment, the first working end 323A of the upper locking tongue 32A is provided with a first slot, and the sheath 3002 forms a first engaging portion that engages with the first slot. The upper locking tongue 32A is applied with force through the cooperation of the first engaging portion and the first slot. The second working end 323B of the lower locking tongue 32B is provided with a second slot, and the lower end of the wire core 3001 extends from the sheath 3002 to form a second engaging portion that engages with the second slot. The lower locking tongue 32B is applied with force through the cooperation of the second engaging portion and the second slot.

[0044] like Figure 11As shown, in some embodiments, the automatic lifting reset drive assembly 400 includes: a lifting push rod 4001 connected to the lifting button 200; a first lifting link 4002 and a second lifting link 4003, the first ends of the first lifting link 4002 and the second lifting link 4003 being hinged to the lifting push rod 4001, the middle portion being hinged to the platform housing 100, and the opposite second ends being connected to the pull cable assembly 300; and a lifting reset spring 4004 connected between the second ends of the first lifting link 4002 and the second lifting link 4003. Specifically, the upper end of the wire core 3001 extends from the sheath 3002 and connects to the second end of the first lifting link 4002, and the sheath 3002 is connected to the second end of the second lifting link 4003.

[0045] When the user actuates (presses) the lifting button 200, the lifting button 200 moves from the first position to the second position (i.e., moves upward), causing the lifting push rod 4001 to move upward, thereby causing the first lifting link 4002 and the second lifting link 4003 to pivot around the hinge point with the platform housing 100, and the corresponding second ends move away from each other. The second end of the first lifting link 4002 drives the pull wire core 3001 to move to the left, causing the second working end 323B of the lower locking tongue 32B to move upward until the lower locking tongue 32B abuts against the lower surface of the locking tongue limit block 35. The second end of the second lifting link 4003 drives the sheath 3002 to move to the right, causing the first working end 323A of the upper locking tongue 32A to move downward until the upper locking tongue 32A abuts against the upper surface of the locking tongue limit block 35, thereby unlocking the lifting locking assembly 3. At this time, the lifting return spring 4004 is stretched.

[0046] When the user releases the lifting button 200, the lifting reset spring 4004 retracts, causing the second ends of the first lifting link 4002 and the second lifting link 4003 to move closer to each other. The first lifting link 4002 and the second lifting link 4003 pivot around the hinge point with the platform housing 100, causing the lifting push rod 4001 to move down, thereby causing the lifting button 200 to return to the first position. The second end of the first lifting link 4002 causes the pull wire core 3001 to move to the right, and the second end of the second lifting link 4003 causes the sheath 3002 to move to the left. The first working end 323A of the upper locking tongue 32A and the second working end 323B of the lower locking tongue 32B move up and down respectively under the elastic force of the elastic element 33, thereby locking the lifting locking assembly 3.
