[0033] Embodiment 1

[0034] Tables are a common piece of furniture, widely used in ordinary families and offices. At present, people have higher and higher requirements for tables, hoping to improve portability while retaining the traditional functions of tables. At the same time, people of different heights have different requirements for the height of tables. Traditional fixed-height tables have certain limitations and cannot meet the needs of different people. Therefore, it is also hoped that improvements can be made in the adjustable height function of tables.

[0035] At present, most of the lifting tables on the market are used to replace the fixed-height tables. Most of the existing lifting tables do not have a heating function, and the desktop temperature is low, especially in winter, it is not easy for users to enter the study or work state. In addition, the existing lifting tables can only adjust the height of the table legs, and cannot adjust the relative position between the desktop and the table legs.

[0036] See also Figure 1-Figure 3 The present embodiment provides an adjustable study table structure, including a heating table top, an upper frame 160 and a plurality of lifting components.

[0037] The heating desktop 100 includes a first radiation panel 110, a heating layer 120, and a second radiation panel 130 which are stacked in sequence from top to bottom. A packaging coating is provided around the edge of the heating layer 120 to form a packaging structure. The power connection end of the heating layer 120 extends out of the packaging structure. The heating layer 120 is controlled by a thermostat 140. The thermostat 140 includes a power control circuit and a temperature adjustment button. The temperature adjustment button is exposed and installed on the lower surface of the heating desktop 100 and is connected to a variable resistor in the power control circuit. The power control circuit is electrically connected to the power connection end of the heating layer 120. By rotating the temperature adjustment button, the current in the power control circuit is adjusted to control the output power of the heating layer 120, thereby adjusting the surface temperature of the heating desktop 100.

[0038] The shape of the heating desktop 100 is not limited, and can be square, circular, semicircular, etc. The first radiation panel 110 and the second radiation panel 130 are of the same size and symmetrically arranged, and the heating layer 120 is sandwiched between the two. The encapsulation coating can be a high-temperature resistant glue, and the edges of the first radiation panel 110 and the second radiation panel 130 are bonded and fixed by high-temperature resistant glue to form an integrated structure. The first radiation panel 110 and the second radiation panel 130 can be highly dense rock board materials, which have good acid and alkali resistance and thermal shock resistance, can prevent surface corrosion and better adapt to intermittent heating working environments.

[0039] The upper frame 160 is fixedly connected to the bottom surface of the heating table. Specifically, the upper frame 160 is a ring-shaped hollow aluminum alloy square tube, and a avoidance structure is formed at the installation position of the upper frame 160 corresponding to the temperature controller.

[0040] The lifting assembly includes a lower frame 170 at its upper end, which can be slidably connected with the upper frame 160 along a horizontal plane. The lifting assembly also includes an upper tube body 800 and a lower tube body 200 that are nested inside and outside. The upper tube body 800 is nested with a screw rod 300, and the top of the screw rod 300 is equipped with a gear box 400 that is transmission-connected with the screw rod 300. The upper end of the gear box 400 is fixedly connected to the lower frame 170, and the gear box 400 is also equipped with a handle body 600. The inner cavity of the lower tube body 200 is fixed with a screw rod sleeve 210 that cooperates with the screw rod 300, and the screw rod 300 drives the sliding operation between the upper tube body 800 and the lower tube body 200 in the vertical direction.

[0041] Specifically, the lower tube body 200 is one of a hollow square tube, a hollow round tube or a hollow triangular tube. A transmission cavity is provided in the lower tube body 200, and a screw sleeve 210 is fixedly provided in the transmission cavity on the same height level. In order to make the heating table top have the longest movable stroke, the screw sleeve 210 can be set at the top of the transmission cavity. The screw rod 300 is vertically arranged in the transmission cavity and is screwed to the screw sleeve 210. The length of the screw rod 300 is adapted to the length of the lower tube body 200.

[0042] By shaking the handle body 600 in a clockwise / counterclockwise direction, the screw rod 300 is driven to rotate around its axis. When the screw rod 300 rotates, since the screw rod sleeve 210 is fixed, the screw rod 300 rises or falls with the rotation direction of the handle body 600, thereby driving the heating table top above the screw rod 300 to rise or fall. The screw rod 300 itself has a self-locking function, and can achieve precise positioning at any point without loading an external locking function; by pushing / pulling the heating table top, the upper frame 160 and the lower frame 170 slide, thereby driving the heating table top to move forward or backward facing the user; the above two adjustment methods are used in combination, so that the user can adjust the height of the study table and the distance between the heating table top and the user according to their own physique characteristics and habitual sitting posture, thereby improving the user's experience.

[0043] The multiple gear boxes 400 are on the same level, and there is a single transmission shaft 500 that passes through any gear box 400 and rotates with the gear box 400. Please refer to Figure 4The gear box 400 includes a housing 430 and a first direction-changing gear 410 accommodated in the housing 430. The housing 430 of the gear box 400 is provided with an opening for allowing the transmission shaft 500 to extend into the gear box 400 and for allowing the transmission shaft 500 to pass through the gear box 400. A single transmission shaft 500 passes through any of the gear boxes 400. A second direction-changing gear 420 is sleeved on the transmission shaft 500 at a position corresponding to the first direction-changing gear 410. The first direction-changing gear 410 and the second direction-changing gear 420 are meshed for transmission, and at least one of the first direction-changing gears 410 is also meshed with the transmission handle body 600. When the handle body 600 is shaken, the first direction-changing gear 410 transmits torque to the second direction-changing gear 420, and the second direction-changing gear 420 rotates to drive the lead screw 300 to rotate around its axial direction. Since all the gear boxes 400 are transmitted torque by a single transmission shaft 500, all the lead screws 300 are raised and lowered at the same time to avoid the occurrence of a tilting of the heated desktop.

[0044] Please refer to Figure 7 The upper frame 160 is provided with a plurality of screw holes 161 spaced apart along its sliding direction, and a plurality of sets of screws 171 are passed through the corresponding screw holes 161 on the lower frame 170. The screws 171 are used to lock the position of the upper frame 160 on its sliding path, thereby determining the distance relationship between the heating desktop and the user.

[0045] In some embodiments, the transmission shaft 500 includes a transmission hexagonal rod 510 and a transmission sleeve 520 sleeved on the transmission hexagonal rod 510, and the second direction-changing gear 420 is sleeved on the transmission sleeve 520. Both ends of the transmission hexagonal rod 510 pass through two gear boxes 400 at the same height, and the middle part of the transmission hexagonal rod 510 is exposed outside the gear box 400. A handle body 600 is also installed at one end of the transmission hexagonal rod 510.

[0046] The heating layer includes a graphene thermal conductive coating 121 and a circuit coating 122. The graphene thermal conductive coating 121 covers the opposite surfaces of the first radiation panel and the second radiation panel to form a surface covering, and the opposite ends of the circuit coating 122 constitute a positive electrode and a negative electrode. Compared with the traditional line heating mode, the graphene coating constituting the surface heating generates heat more evenly and has a larger heating area, and the ultra-high thermal conductivity of graphene greatly improves the electrothermal conversion efficiency.

[0047] In some embodiments, the heating layer further includes an overheat protection component. Specifically, the overheat protection component includes a temperature sensor, the sensing contact of the temperature sensor is arranged close to the heating layer, and the thermostat is electrically connected to the temperature sensor. When the detected temperature is higher than the preset temperature, the thermostat controls the heating layer to reduce the heating power.

[0048] Please refer to Figure 5In some embodiments, a heat-insulating layer 150 is attached to the side of the heating layer facing away from the lifting component. Specifically, the heat-insulating layer 150 is made of a material with a low thermal conductivity, such as a plastic board, a European pine board, etc. Under the heat-insulating effect of the heat-insulating layer 150, the heat transferred downward by the heating layer is greater than the heat transferred upward. The reason for this design is that when a person sits in front of a heating table, the hands can be directly attached to the table to keep warm, but the legs are still some distance away from the heating table. If the heat radiated from the upper and lower sides of the heating table is the same, it is not conducive to keeping the legs warm. And in the present application, since the heating table can be raised and lowered, the distance between the legs and the heating table can also be actively adjusted, so that the heating table is more conducive to keeping the legs warm. In some other embodiments, the second radiation panel can be thinned to allow the heating layer to radiate more heat downward.

[0049] Please refer to Figure 6 In some embodiments, a barrier layer 700 is provided convexly downwardly around the second radiation panel, and a notch is provided in the barrier layer 700 relative to the handle body 600 and the thermostat. The barrier layer 700 is helpful in reducing the radiant heat dissipated from the second radiation panel to the surroundings. On the other hand, since the surface temperature of the second radiation panel is relatively high, the human body may be burned if it touches the panel, and the barrier layer 700 can also reduce the probability of the human body accidentally touching the second radiation panel. A notch is provided at the position corresponding to the handle body 600 to allow the handle body 600 to extend out of the barrier layer 700, and a notch is provided at the position corresponding to the thermostat to adjust the temperature. In other embodiments, a reflective heat film is attached to the side of the barrier layer 700 facing the second radiation panel to enhance the ability of the barrier layer 700 to reflect heat and enhance the warming effect of the barrier layer 700.
