Description

Technical Field

[0001] This invention relates to the field of electronic product technology, and more specifically, to a height-adjustable electronic product. Background Technology

[0002] Electronic products are products that operate based on electrical energy, and mainly include: watches, smartphones, telephones, televisions, DVD players, video recorders, camcorders, radios, tape recorders, speaker systems, laser disc players, computers, game consoles, and mobile communication products. They are called electronic products because early products primarily used vacuum tubes as their basic component.

[0003] Chinese patent application CN208951611U discloses an adjustable-height monitor, comprising a monitor body 1, a movable rod 2, a fixed sleeve 3, a base 4, an adjusting block 5, and a gear 6. The monitor body 1 is fixedly connected to the movable rod 2, which has a first rack 23. The fixed sleeve 3 is fixedly connected to the base 4. The adjusting block 5 is fixed to the fixed sleeve 3 and has a second rack 51. The gear 6 has a third rack 61 and a rotating handle 63 fixedly connected. When adjusting the height of the monitor body 1, pressing the rotating handle 63 inward disengages the third rack 61 from the second rack 51. Rotating the rotating handle 63 causes the third rack 61 to drive the first rack 23 to rise or fall, thereby raising or lowering the monitor body 1. When adjusted to the appropriate position, pull the rotating handle 63 out to both sides of the adjusting block 5 so that the third rack 61 on the surface of the gear 6 meshes with the second rack 51, thereby fixing the gear 6. At the same time, the third rack 61 on the surface of the gear 6 meshes with the first rack 23. When the gear 6 is stationary, the movable rod 2 will also remain stationary, thereby achieving the effect of fixing the height of the display body 1.

[0004] The above-mentioned method requires repeatedly pulling and rotating the rotating handle 63 to adjust and lock the height of the display body 1, which is cumbersome, time-consuming and laborious. There is an urgent need for an electronic product that is simple and convenient to operate for height adjustment. Summary of the Invention

[0005] To address the above shortcomings, the technical problem to be solved by the present invention is to provide a height-adjustable electronic product, the height of which is simple and convenient to adjust.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0007] A height-adjustable electronic product includes: an electronic product body and a base, the electronic product body having a vertical sliding member, the base having a vertical support member, the vertical sliding member being slidably connected to the vertical support member via a guide rail device, and a locking structure for locking the position of the vertical sliding member being provided between the vertical sliding member and the vertical support member.

[0008] The locking structure includes a locking base component, a rotating rod, a rotating rod stop structure, and two elastic friction heads. The locking base component is fixed to the vertical support component. The rotating rod is rotatably mounted on the locking base component. The rotating rod stop structure is used to prevent the rotating rod from rotating. The two elastic friction heads are symmetrically arranged on the first end of the rotating rod. An elastic friction head component is provided between the elastic friction head and the rotating rod.

[0009] The vertical sliding member has two vertically opposite friction surfaces. When the elastic friction head contacts the friction surfaces, the position of the vertical sliding member is locked.

[0010] Preferably, the elastic friction head is spherical or arc-shaped, and there is a gap between the elastic friction head and the rotating rod;

[0011] The friction head elastic element is provided in at least two parts, and the friction head elastic element is evenly distributed around the circumference of the elastic friction head.

[0012] Preferably, the elastic friction head includes a spherical or arc-shaped elastic friction head body and a slide rod fixedly connected to the elastic friction head body, wherein the slide rod is slidably connected to the rotary rod;

[0013] The friction head elastic element is provided in at least two parts, and the friction head elastic element is evenly distributed around the elastic friction head in the circumference.

[0014] Alternatively, the friction head elastic element may be disposed between the slide rod and the rotary rod.

[0015] Preferably, the swivel stop structure includes two elastic friction wheels disposed opposite to each other on both sides of the swivel, the elastic friction wheels being rotatably mounted on the locking base via a wheel axle, and there is damping between the elastic friction wheels and the wheel axle;

[0016] Alternatively, the swivel stop structure includes two elastic friction elements fixedly disposed opposite each other on both sides of the swivel.

[0017] Preferably, the second end of the rotary rod is provided with a knob, and a clutch structure is provided between the knob and the rotary rod. When the knob and the rotary rod are engaged, rotating the knob can drive the rotary rod to rotate.

[0018] Preferably, the knob is rotatably mounted on the rotary rod;

[0019] The clutch structure includes a clutch lever located inside the knob. The end of the clutch lever is provided with a moving engagement portion. The clutch lever and / or the moving engagement portion are slidably connected to the knob. A knob elastic element is provided between the clutch lever and the knob. The second end of the lever is provided with a stationary engagement portion adapted to the moving engagement portion. Pressing the clutch lever causes the moving engagement portion to engage with the stationary engagement portion.

[0020] Preferably, the clutch lever is driven by a wedge plate to engage the moving engagement part with the stationary engagement part. The first end of the wedge plate is connected to a sliding plate, which is slidably mounted on the knob. A wedge plate elastic element is provided between the second end of the wedge plate and the knob.

[0021] Preferably, the slide plate passes through the knob, and an elastic element is provided between the end of the slide plate extending out of the knob and the knob.

[0022] Preferably, the locking base component is a T-shaped shell, the rotary rod, the rotary rod stop structure, and the two elastic friction heads are all located in the inner cavity enclosed by the T-shaped shell, the rotary rod has a knob at one end extending out of the T-shaped shell, the T-shaped shell has an elastic friction head hole, and the elastic friction head extends out of the elastic friction head hole and contacts the friction surface.

[0023] Preferably, a buffer structure is provided between the base and the electronic product body.

[0024] After adopting the above technical solution, the beneficial effects of the present invention are:

[0025] When adjusting the height of the electronic product, rotating the knob disengages the elastic friction head from the friction surface, adjusting the product to the desired height. Then, rotating the knob again brings the elastic friction head back into contact with the friction surface. Under the action of the compressed elastic element of the friction head, the head presses firmly against the surface. The friction between the elastic friction head and the surface supports the product. Simultaneously, the knob's stop structure locks its position, preventing further rotation and thus securely locking the product's height. Compared to existing technologies, this method only requires rotating the knob to adjust and lock the product's height, making adjustment simple and operation convenient and quick.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0035] like Figure 1 and Figure 2 As shown in the figure, a height-adjustable electronic product includes: an electronic product body 1 and a base 2. The electronic product body 1 is provided with a vertical sliding member 3, and the base 2 is provided with a vertical support member 4. The vertical sliding member 3 is slidably connected to the vertical support member 4 through a guide rail device. A locking structure 5 for locking the position of the vertical sliding member 3 is provided between the vertical sliding member 3 and the vertical support member 4.

[0036] The locking structure 5 includes a locking base 51, a rotating rod 52, a rotating rod stop structure, and two elastic friction heads 53. The locking base 51 is fixedly connected to the vertical support 4. The rotating rod 52 is rotatably mounted on the locking base 51. The rotating rod stop structure is used to prevent the rotating rod 52 from rotating. The two elastic friction heads 53 are symmetrically arranged on the first end of the rotating rod 52. An elastic friction head is provided between the elastic friction head 53 and the rotating rod 52.

[0037] The vertical sliding member 3 has two vertically opposite friction surfaces. When the elastic friction head 53 contacts the friction surfaces, the vertical sliding member 3 is locked in position. The elastic friction head 53 is made of rubber or silicone.

[0038] When adjusting the height of the electronic product body 1, rotating the rotary rod 52 disengages the elastic friction head 53 from the friction surface, adjusting the electronic product body 1 to a suitable height. Then, rotating the rotary rod 52 again brings the elastic friction head 53 into contact with the friction surface. Under the action of the compressed elastic element of the friction head, the elastic friction head 53 presses tightly against the friction surface. The friction between the elastic friction head 53 and the friction surface supports the electronic product body 1. Simultaneously, the rotary rod 52 is locked in position by the rotary rod stop structure, preventing rotation and thus firmly locking the height of the electronic product body 1. Compared with existing technologies, only rotating the rotary rod 52 is needed to adjust and lock the height of the electronic product body 1, making adjustment simple and operation convenient and quick.

[0039] like Figure 3 As shown in the illustrated embodiment, the elastic friction head 53 includes a spherical or arc-shaped elastic friction head body 531 and a slide rod 532 fixedly connected to the elastic friction head body 531. The slide rod 532 is slidably connected to the rotating rod 52. The friction head elastic element is disposed between the elastic friction head body 531 and the rotating rod 52. Preferably, the friction head elastic element is a friction head memory metal 54 or a metal spring. At least two friction head memory metals 54 are provided, and the friction head memory metals 54 are evenly distributed around the elastic friction head body 531. Alternatively, the friction head elastic element is disposed between the slide rod 532 and the rotating rod 52. The friction head elastic element is preferably a helical spring or a rubber spring, etc.

[0040] In another embodiment, the elastic friction head 53 is spherical or arc-shaped, and there is a gap between the elastic friction head 53 and the rotating rod 52; the elastic element of the friction head is a friction head memory metal 54 or a metal spring sheet, and at least two friction head memory metals 54 are provided, and the friction head memory metals 54 are evenly distributed around the elastic friction head 53.

[0041] like Figure 4 and Figure 5As shown in the illustrated embodiment, the rotating rod stop structure includes two elastic friction wheels 55 disposed opposite each other on both sides of the rotating rod. The elastic friction wheels 55 are rotatably mounted on the locking base 51 via axle 56. There is damping between the elastic friction wheels 55 and the axle 56, such as by providing a damping plate or a damping bearing, and the frictional resistance is greater than 10N. The rotating rod 52 is pressed between the two elastic friction wheels 55. When rotating the rotating rod 52, it needs to overcome the frictional force between the elastic friction wheels 55 and the axle 56. When the rotating rod 52 is stopped, the rotating rod 52 is locked under the action of the frictional force between the elastic friction wheels 55 and the axle 56. The elastic friction wheels 55 are made of rubber or silicone, etc.

[0042] In another embodiment, the swivel stop structure includes two elastic friction elements fixedly disposed opposite each other on both sides of the swivel 52, with the swivel 52 pressed between the two elastic friction elements. The elastic friction elements are made of rubber or silicone, etc.

[0043] To prevent accidental rotation of the rotary rod 52, a knob 6 is provided at the second end of the rotary rod 52. A clutch structure is provided between the knob 6 and the rotary rod 52. When the knob 6 and the rotary rod 52 are engaged, rotating the knob 6 can drive the rotary rod 52 to rotate, thereby adjusting or locking the height of the electronic product body 1. When the knob 6 and the rotary rod 52 are disengaged, even if the knob 6 is rotated, the rotary rod 52 will not rotate, thus preventing the electronic product body 1 from suddenly falling.

[0044] like Figure 6 As shown, knob 6 is rotated and fitted onto the second end of rotary rod 52;

[0045] The clutch structure includes a clutch lever 61 located within the knob 6. The end of the clutch lever 61 has a movable engagement portion, which is slidably connected to the knob 6. A knob memory metal 62 or a metal spring is provided between the clutch lever 61 and the knob 6. The second end of the rotary rod 52 has a static engagement portion adapted to the movable engagement portion. Pressing the clutch lever 61 engages the movable engagement portion with the static engagement portion. After the external force is removed, the clutch lever 61 returns to its original position under the action of the knob memory metal 62, and the movable engagement portion disengages from the static engagement portion. The knob memory metal 62 can not only be used to drive the clutch lever 61 to return to its original position, but also serves as a bridge for transmitting torque. When the knob 6 is rotated, the force is transmitted to the clutch lever 61 through the knob memory metal 62. Preferably, the movable engagement portion is a cross-shaped rod 63, and the static engagement portion is a cross-shaped groove 521. Triangular blocks with triangular grooves, T-shaped rods, and T-shaped grooves can also be used.

[0046] In another embodiment, the clutch structure includes a clutch lever 61 located inside the knob 6. The clutch lever 61 can slide relative to the knob 6 but cannot rotate relative to it. For example, the clutch lever 61 is square. A sliding sleeve is fixed inside the knob 6, and the clutch lever 61 slides in the sliding sleeve. The end of the clutch lever 61 is provided with a moving engagement part. A knob elastic element, such as a coil spring or a rubber spring, is provided between the clutch lever 61 and the knob 6. The second end of the rotary rod 52 is provided with a static engagement part that is adapted to the moving engagement part. Pressing the clutch lever causes the moving engagement part to engage with the static engagement part.

[0047] The clutch lever 61 is driven by a wedge plate 64 to engage the moving and stationary parts. A slide plate 65 is connected to the first end of the wedge plate 64, and the slide plate 65 is slidably mounted on the knob 6. An elastic element, such as a wedge plate shape memory metal 66, a coil spring, or a rubber spring, is provided between the second end of the wedge plate 64 and the knob 6. As the wedge plate 64 slides, the clutch lever 61 gradually approaches the second end of the knob 52 under the push of the inclined surface of the wedge plate 64, engaging the moving and stationary parts. When the external force is removed, the wedge plate 64 returns to its original position under the action of the wedge plate shape memory metal 66, and the knob shape memory metal 62 pushes the clutch lever 61 back to its original position, disengaging the moving and stationary parts.

[0048] Since the wedge plate 64 is located inside the knob 6, it is inconvenient to push the wedge plate 64 with your hand. The slide plate 65 can pass through the knob 6, and the wedge plate 64 can be driven to move by directly pressing the outer end of the slide plate 65, which is convenient to operate.

[0049] The end of the skateboard 65 that extends out of the knob 6 is provided with a skateboard elastic element, such as a skateboard rubber sheet 67, memory metal and metal spring, etc., to assist the skateboard 65 in resetting. The skateboard rubber sheet 67 can also protect the skateboard 65.

[0050] The locking base component 51 is a T-shaped shell. The rotating rod 52, the rotating rod stop structure and the two elastic friction heads 53 are all located in the inner cavity enclosed by the T-shaped shell. The end of the rotating rod 52 that extends out of the T-shaped shell is provided with a knob 6. The T-shaped shell is provided with an elastic friction head hole 511. The elastic friction head 53 extends out of the elastic friction head hole 511 and contacts the friction surface.

[0051] A pneumatic or hydraulic buffer is provided between the base 2 and the electronic product body 1. The pneumatic buffer includes a fixed cylinder 71, a first-stage telescopic rod 72, and a second-stage telescopic rod 73. Significant friction exists between the first-stage telescopic rod 72 and the fixed cylinder 71, and between the first-stage telescopic rod 72 and the second-stage telescopic rod 73. A top plate 74 is fixed to the upper end of the second-stage telescopic rod 73, and the top plate 74 abuts against the electronic product body 1. When adjusting the height of the electronic product body 1, the elastic friction head 53 disengages from the friction surface. Due to the support of the pneumatic buffer 7, the electronic product body 1 does not suddenly descend, but descends slowly due to the action of air pressure and friction, protecting the electronic product body 1. Furthermore, the pneumatic buffer 7 bears part of the weight of the electronic product body 1, facilitating height adjustment by personnel.

The scope of protection of the present invention is determined by the claims.
