[0002] 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.

[0003] At present, most lifting tables on the market are used to replace 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 learning or working state. Some lifting tables have a heating desktop structure, but the lifting structure is relatively complicated. Generally, a motor is installed on each table leg, and the desktop is synchronously lifted by multiple motors. However, this method requires high matching accuracy of each motor. If a certain offset is generated, the desktop will be skewed. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art, the present application provides a liftable heating table structure, comprising:

[0005] The heating desktop comprises a first radiation panel, a heating layer, and a second radiation panel which are stacked in sequence from top to bottom, a packaging coating is arranged around the edge of the heating layer to form a packaging structure, a power connection end of the heating layer extends out of the packaging structure, and the heating layer is controlled by a temperature controller;

[0007] A screw rod is provided corresponding to the hollow leg, the screw rod is vertically arranged in the transmission cavity and is threadedly connected to the lifting nut sleeve, and the length of the screw rod is adapted to the length of the hollow leg;

[0008] A plurality of steering transmission boxes, the upper ends of which are fixedly connected to the bottom surface of the heating table top, and the steering transmission box is provided with a first direction-changing gear fixedly sleeved on the top end of the screw rod;

[0009] A single transmission shaft passes through any steering transmission box, a second direction-changing gear is sleeved on the transmission shaft corresponding to the position of the first direction-changing gear, the first direction-changing gear is meshed with the second direction-changing gear for transmission, and at least one of the first direction-changing gears is also meshed with a hand crank for transmission.

[0010] In a possible implementation, a thermal insulation layer is attached to the side of the heat-generating layer facing away from the hollow leg.

[0011] In a possible implementation manner, a thickness of the first radiation panel is greater than a thickness of the second radiation panel.

[0012] In a possible implementation manner, the transmission shaft includes a transmission hexagonal rod and a transmission sleeve sleeved on the transmission hexagonal rod, and the second direction-changing gear is sleeved on the transmission sleeve.

[0013] In a possible implementation, the hollow leg is a hollow square tube, a hollow round tube or a hollow triangular tube.

[0014] In a possible implementation, the heating layer includes a graphene thermal conductive coating and a circuit coating, the graphene thermal conductive coating covers the opposite surfaces of the first radiation panel and the second radiation panel to form surface coverage, and the opposite ends of the circuit coating constitute a positive electrode and a negative electrode.

[0015] In a possible implementation, the heating layer further includes an overheat protection component.

[0016] In a possible implementation, a barrier layer is provided circumferentially and protruding downwardly around the second radiation panel, and a gap is formed in the barrier layer relative to the hand crank and the thermostat.

[0017] In a possible implementation manner, a heat reflective film is attached to a side of the blocking layer facing the second radiation panel.

[0018] The present application also provides a study table, comprising the above-mentioned liftable heating table structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The heating table structure in the present application is easy to use. By shaking the hand crank in a clockwise / counterclockwise direction, the first direction-changing gear transmits torque to the second direction-changing gear. The rotation of the second direction-changing gear drives the lead screw to rotate around its axis. When the lead screw rotates, the lifting nut sleeve is fixed, so the lead screw rises or falls with the rotation direction of the hand crank, thereby driving the heating table top above the lead screw to rise or fall. Since all steering transmission boxes transmit torque through a single transmission shaft, all lead screws rise and fall at the same time to avoid the heating table top from tilting.

[0021] 2. Since the heat-generating layer is attached to the side facing away from the hollow leg with a heat-insulating layer, and the heat-insulating layer is made of a material with a low thermal conductivity, the heat radiated downward from the heat-generating tabletop is higher than the heat radiated upward, and this design is conducive to heating and keeping people's legs warm.

[0036] Embodiment 1

[0037] At present, most lifting tables on the market are used to replace 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 learning or working state. Some lifting tables have a heating desktop structure, but the lifting structure is relatively complicated. Generally, a motor is installed on each table leg, and the desktop is synchronously lifted by multiple motors. However, this method requires high matching accuracy of each motor. If a certain offset is generated, the desktop will be skewed.

[0038] See also Figure 1-Figure 3 As can be seen from the figure, the heating table structure includes a heating tabletop 100, a plurality of hollow legs 200, a screw rod 300 corresponding to the hollow legs 200, a steering transmission box 400 and a transmission shaft 500.

[0039] 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.

[0040] 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.

[0041] A plurality of hollow legs 200 are arranged at intervals around the edge of the heating table top 100. The hollow legs 200 are one of a hollow square tube, a hollow round tube or a hollow triangular tube. A transmission cavity is provided in the hollow legs 200, and a lifting nut 210 is fixedly provided in the transmission cavity on the same height plane. In order to make the heating table top 100 have the longest movable stroke, the lifting nut 210 can be set at the top of the hollow legs 200. The screw rod 300 is vertically arranged in the transmission cavity and is screwed to the lifting nut 210 sleeve, and the length of the screw rod 300 is adapted to the length of the hollow legs 200.

[0042] The upper end of the steering transmission box 400 is fixedly connected to the bottom surface of the heating table 100, and a first direction-changing gear 410 fixedly sleeved on the top of the screw rod 300 is arranged in the steering transmission box 400. Figure 4 The steering transmission box 400 includes a housing 430 and a first direction-changing gear 410 accommodated in the housing 430. An opening is provided on the housing 430 of the steering transmission box 400 to allow the transmission shaft 500 to extend into the steering transmission box 400 and to allow the transmission shaft 500 to pass through the steering transmission box 400. A single transmission shaft 500 passes through any steering transmission box 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 is meshed with the second direction-changing gear 420 for transmission, and at least one of the first direction-changing gears 410 is also meshed with a hand crank 600 for transmission.

[0043] The heating table structure of the present application is easy to use. By shaking the hand crank 600 clockwise / counterclockwise, the first direction-changing gear 410 transmits torque to the second direction-changing gear 420. The second direction-changing gear 420 rotates to drive the screw rod 300 to rotate around its axis. When the screw rod 300 rotates, the lifting nut 210 is fixed, so the screw rod 300 rises or falls with the rotation direction of the hand crank 600, thereby driving the heating table top 100 above the screw rod 300 to rise or fall. Since all the steering transmission boxes 400 transmit torque through a single transmission shaft 500, all the screw rods 300 are lifted and lowered at the same time, avoiding the heating table top 100 from tilting.

[0044] Please refer to Figure 5 In some embodiments, the heat-generating layer 120 is attached with a heat-insulating layer 150 on the side facing away from the hollow leg 200. 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 heat-generating layer 120 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 100. 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 100 can be raised and lowered, the distance between the legs and the heating table 100 can also be actively adjusted, so that the heating table 100 is more conducive to keeping the legs warm. In some other embodiments, the second radiation panel 130 can be thinned to make the heating layer 120 radiate more heat downward.

[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. The two ends of the transmission hexagonal rod 510 pass through two steering transmission boxes 400 at the same height, and the middle part of the transmission hexagonal rod 510 is exposed outside the steering transmission box 400. A hand crank 600 is also installed at one end of the transmission hexagonal rod 510.

[0046] The heating layer 120 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 110 and the second radiation panel 130 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 120 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 120, and the thermostat 140 is electrically connected to the temperature sensor. When the detected temperature is higher than the preset temperature, the thermostat 140 controls the heating layer 120 to reduce the heating power.

[0048] Please refer to Figure 6 In some embodiments, a barrier layer 700 is provided convexly downwardly around the second radiation panel 130, and a notch is provided in the barrier layer 700 relative to the hand crank 600 and the thermostat 140. The barrier layer 700 is conducive to reducing the radiant heat dissipated from the second radiation panel 130 to the surroundings. On the other hand, since the surface temperature of the second radiation panel 130 is relatively high, if the human body touches it, it may be burned, and the barrier layer 700 can also reduce the probability of the human body accidentally touching the second radiation panel 130. A notch is provided at the position corresponding to the hand crank 600 to allow the hand crank 600 to extend out of the barrier layer 700, and a notch is provided at the position corresponding to the thermostat 140 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 130 to enhance the ability of the barrier layer 700 to reflect heat and enhance the warming effect of the barrier layer 700.
