Technical Field

[0001] The utility model belongs to the technical field of automobile seats and relates to a table board for automobile seats. Background Art

[0002] At present, for the comfort of passengers, some vehicles have tables for placing cups or items installed on the back of the front seats. For example, a Chinese patent document discloses a seat table installation assembly and a vehicle (application number: 20222599233.0), including a seat frame, a hanger and a table. The seat frame is installed with a preset rod; the upper part of the hanger is hung on the preset rod, and the lower part is connected to the seat frame through a connector; the table forms two sets of four-bar mechanisms with the hanger through two sets of connecting rods. However, the seat table installation assembly and the vehicle's table only have a single function of supporting items when in use, and cannot meet the diverse needs of passengers. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and propose a table board for car seats. The technical problem to be solved by the utility model is how to enrich the functions of the car seat table board to meet the diverse needs of passengers.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A table top for a car seat includes a table top body, characterized in that a heat conduction pad is provided on the table top body, a semiconductor refrigeration plate for heating or cooling the heat conduction pad is provided on the heat conduction pad, a receiving groove is provided on the table top body, a hanging rod is provided in the receiving groove, the hanging rod has a hanging part for hanging objects, and the hanging rod can be rotated relative to the table top body to make the hanging part be located above the heat conduction pad.

[0006] In addition to the unfolding or folding function of traditional seat tables, the table board body also has heating and cooling functions by providing a heat conduction pad and a semiconductor refrigeration sheet for heating or cooling the heat conduction pad on the table board body. The table board body can be used to heat or cool the liquid in a water cup and heat meals, etc. By providing a hidden and storable hanging rod, containers such as water cups can be hung on the hanging rod, and the distance between containers such as water cups and the heat source or cold source can be adjusted to avoid the temperature of the liquid in containers such as water cups being too high or too low, and it is also convenient to keep the liquid in the containers warm or cold, thereby enriching the functions of the car seat table board to meet the diverse needs of passengers.

[0007] In the above-mentioned table board for a car seat, a storage slot is also provided on the table board body, a clothes hanger is provided in the storage slot, and the clothes hanger can be moved relative to the table board body to extend out of the storage slot and locked. When the clothes hanger is moved to extend out of the storage slot of the table board body and locked, it can be used to hang clothes, thereby enriching the functions of the car seat table board to meet the diverse needs of passengers.

[0008] In the above-mentioned car seat table, a PCT heating plate is arranged in the storage slot, and the PCT heating plate is arranged adjacent to the hanger. When the hanger is moved out of the storage slot of the table body and locked, the PCT heating plate can dry the hanging clothes to a certain extent, thereby enriching the functions of the car seat table to meet the diverse needs of passengers. The PCT heating plate has the advantages of power saving, simple structure, low use cost and relatively stable heat. The PCT heating plate can be made into an independent module with flexible layout and easy installation. PTC is the abbreviation of Positive Temperature Coefficient. It is a special resistance material. The characteristic of this material is that the resistance value of the PTC material will increase with the increase of temperature. When the PCT heating plate is powered on, the current passes through the PTC heating plate. According to the characteristic curve, the resistance increases rapidly, so that the PTC heating plate generates heat. At this time, the PTC heating plate works under the condition of constant current, and its heating power is proportional to the square of the current. Due to the resistance characteristics of the PTC material, when the PTC heating plate starts to work, the temperature rises, resulting in an increase in resistance, thereby reducing the amount of current passing through. This self-control temperature characteristic enables the PTC heating plate to automatically reduce the current after reaching the preset temperature, thereby achieving temperature stability and safer use.

[0009] In the above-mentioned table board for car seats, the clothes hanger is provided with a guide hole along its length direction, and a fixing bolt that cooperates with the limiting guide of the guide hole is fixedly connected to the groove wall of the storage groove, and the fixing bolt is inserted into the guide hole. The screw rod of the fixing bolt and the hole wall of the guide hole can limit each other along the radial direction of the bolt, and the bolt head of the fixing bolt and the edge of the guide hole can limit each other along the axial direction of the bolt, so that the clothes hanger can move relative to the table board body along a certain path and will not separate from the table board body.

[0010] In the above-mentioned table board for a car seat, the guide holes are provided in plurality and are arranged at intervals along the width direction of the hanger, and the guide holes are arranged in a staggered manner along the length direction of the hanger, and the fixing bolt is passed through each guide hole. The above-mentioned structure makes the movement of the hanger smoother and more accurate.

[0011] In the above-mentioned table board for car seat, a rotating shaft is arranged on the table board body, a pressure block that can swing around the rotating shaft is arranged on the rotating shaft, a clearance hole for exposing the pressure block is opened on the table board body, and the clothes hanger is provided with a plurality of embedded grooves along its length direction, the pressure block is embedded in the embedded grooves, and the pressure block can swing upward to disengage from the embedded grooves, and the rotating shaft is also provided with a torsion spring for swinging the pressure block downward to reset. Through the matching structure of the pressure block and the embedded groove, the user can force the pressure block to rotate around the rotating shaft to disengage from the embedded groove by pressing the pressure block so that the clothes hanger is unlocked and can move freely relative to the table board body. When the clothes hanger moves to the next embedded groove relative to the pressure block, under the action of the restoring force of the torsion spring, the pressure block can be embedded in the embedded groove to re-lock the clothes hanger. The structure is simple and easy to use.

[0012] In the above-mentioned table board for a car seat, the torsion spring is sleeved on the rotating shaft, one end of the torsion spring is connected to the table board body, and the other end of the torsion spring is connected to the pressing block. By connecting the two ends of the torsion spring sleeved on the rotating shaft to the table board body and the pressing block respectively, after the user presses the pressing block to force it to rotate around the rotating shaft, the torsion spring can better generate a restoring force, and then can better drive the pressing block to return to the embedded groove.

[0013] In the above-mentioned table board for car seats, when the clothes hanger moves to the position where the edge of any end of the guide hole abuts against the fixing bolt, the positions of the pressing block and the embedding groove are relatively arranged so that the pressing block is embedded in the embedding groove to form a lock. The above-mentioned structure makes the positions of the two ends of the guide hole correspond to the maximum movement of the clothes hanger initially hidden in the table board body or extended out of the table board body, and by setting the distance between the two embedding grooves at the two ends of the plurality of embedding grooves to be equal to the length of the guide hole, the clothes hanger can be locked when it is initially hidden in the table board body or extended out of the table board body.

[0014] In the above-mentioned table board for car seats, the clothes hanger is T-shaped, and the table board body is also provided with a single-chip microcomputer, a relay, a temperature sensor and a display screen. The single-chip microcomputer controls the heating or cooling of the semiconductor refrigeration plate through the relay, and the temperature sensor is used to detect the temperature of the cold and heat conduction pad in real time. The single-chip microcomputer receives the temperature of the cold and heat conduction pad detected by the temperature sensor and controls the display screen to display the temperature. The T-shaped clothes hanger is convenient for hanging clothes, and also allows the clothes hanger to be better hidden in the table board body. The single-chip microcomputer changes the positive and negative poles of the current flowing into the semiconductor refrigeration plate through the relay, and then controls the semiconductor refrigeration plate to realize the heating function or the cooling function, making the control of the semiconductor refrigeration plate more intelligent. In addition, by setting the temperature sensor and the display screen, the user can intuitively view the heating temperature or the cooling temperature, which is more convenient to use.

[0015] Compared with the prior art, the advantages of the table board for car seats are: in addition to the unfolding or folding function of traditional seat tables, the table board body also has heating and cooling functions, which can be used to heat or cool the liquid in a water cup and heat meals, etc., and by hanging containers such as water cups on the hanging rod, the distance between containers such as water cups and the heat source or cold source can be adjusted to avoid the temperature of the liquid in containers such as water cups being too high or too low, and it is also convenient to keep the liquid warm or cold. At the same time, a hidden clothes hanger and a PCT heating plate are also provided on the table board body. When the clothes hanger is moved to extend out of the storage slot of the table board body and locked, it can be used to hang clothes. When the PCT heating plate is working, it can also dry the hung clothes to a certain extent, thereby enriching the functions of the car seat table board to meet the diverse needs of passengers.

Specifically, the hanger 5 is provided with a guide hole 5a along its length direction, and a fixing bolt 6 that cooperates with the guide hole 5a for limiting and guiding is fixedly connected to the groove wall of the storage groove 1b, and the fixing bolt 6 is passed through the guide hole 5a; a rotating shaft 7 is provided on the table board body 1, and a pressure block 8 that can swing around it is provided on the rotating shaft 7, and a clearance hole 1c for exposing the pressure block 8 is provided on the table board body 1, and the hanger 5 is provided with a plurality of embedded grooves 5b along its length direction, and the pressure block 8 is embedded in the embedded groove 5b, and the pressure block 8 can swing upward to disengage from the embedded groove 5b, and a torsion spring 9 for swinging the pressure block 8 downward to reset is also provided on the rotating shaft 7; the torsion spring 9 is sleeved on the rotating shaft 7, one end of the torsion spring 9 is connected to the table board body 1, and the other end of the torsion spring 9 is connected to the pressure block 8.

[0028] In this embodiment, the guide holes 5a are preferably provided in plurality and are spaced apart along the width direction of the hanger 5, and the guide holes 5a are staggered along the length direction of the hanger 5, and the fixing bolt 6 is passed through each guide hole 5a; preferably, when the hanger 5 moves to a position where the edge of any end of the guide hole 5a abuts against the fixing bolt 6, the positions of the pressing block 8 and the embedding groove 5b are relatively arranged so that the pressing block 8 is embedded in the embedding groove 5b to form a locking state.

[0029] Furthermore, refer to Figure 3-8The clothes hanger 5 is T-shaped, and the table board body 1 is also provided with a single-chip microcomputer, a relay, a temperature sensor and a display screen 11.

The single-chip microcomputer receives the temperature of the heat conduction pad 2 detected by the temperature sensor and controls the display screen 11 to display the temperature.

[0030] The following describes the working principle of the car seat table:

[0031] When it is necessary to heat or cool the food, the user first unfolds the table top body 1 to a horizontal supporting state, and then places the container containing the food on the heat conduction pad 2, and then energizes the semiconductor refrigeration chip 3 so that the semiconductor refrigeration chip 3 heats or cools the heat conduction pad 2, and then the heat conduction pad 2 transfers the heat or cold to the container containing the food to heat or cool the food. Because the on-board power supply used by the semiconductor refrigeration chip 3 when working is direct current, the semiconductor refrigeration chip 3 is controlled by changing the polarity of the direct current to realize the heating function or the cooling function, thereby heating or cooling the heat conduction pad 2, or the single chip microcomputer controls the relay (the relay has a normally open end and a normally closed end) to control the semiconductor refrigeration chip 3 to achieve the heating function or the cooling function. ) to change the positive and negative poles of the current flowing into the semiconductor refrigeration sheet 3 and then control the semiconductor refrigeration sheet 3 to realize the heating function or the cooling function, thereby heating or cooling the heat transfer pad 2. After the food is heated or cooled, the container containing the food can be hung on the hanging portion 4a of the hanging rod 4 to adjust the distance between the container containing the food and the heat source or the cold source to avoid the temperature of the food being too high or too low, and to facilitate the food to be kept warm or cold. In addition, the temperature sensor on the table body 1 can detect the temperature of the heat transfer pad 2 in real time. The single-chip microcomputer receives the temperature of the heat transfer pad 2 detected by the temperature sensor and controls the display screen 11 to display the temperature, so that the user can intuitively view the heating temperature or the cooling temperature. When the use is completed, the user turns off the power of the semiconductor refrigeration sheet 3, stores the hanging rod 4 in the receiving groove 1a, and finally readjusts the table body 1 to the vertical folded state.

[0032] When it is necessary to hang clothes or heat and dry clothes wet by rain, the table board body 1 can be unfolded to a horizontal supporting state or in a vertically folded state. The user presses the pressing block 8 in the giving way hole 1c, so that the pressing block 8 swings around the rotating shaft 7 and disengages from the embedded groove 5b. During this process, the torsion spring 9 is deformed and accumulates energy to make the pressing block 8 swing downward and reset. After the pressing block 8 disengages from the embedded groove 5b, the hanger 5 is in an unlocked state, and the user can pull the hanger 5 to move it out of the storage slot 1b until the next embedded groove 5b moves to the position that is aligned with the pressing block. 8, the pressing block 8 swings downward and resets under the action of the restoring force of the torsion spring 9 (in the position without the embedded groove 5b, the pressing block 8 presses on the hanger 5, and due to the obstruction of the hanger 5, the pressing block 8 cannot continue to swing downward), and the hanger 5 is locked again. At this time, the hanger 5 extends out of the storage slot 1b of the table body 1 and can be used to hang clothes. When the clothes need to be heated and dried, the user turns on the PCT heating plate 10, and the air heated by the PCT heating plate 10 flows out through the notch of the storage slot 1b to heat and dry the clothes. After use, the user turns off the power of the PCT heating plate 10, then presses the pressing block 8 to unlock the hanger 5 and operates the hanger 5 to move and reset, and finally readjusts the table body 1 to the vertical folded state.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
