DETAILED DESCRIPTION

[0027] The specific implementation modes provided by the present invention are described in detail below with reference to the accompanying drawings.

[0028] The reference numerals and components involved in the drawings are as follows:

[0029] The invention provides an intelligent chair that is convenient for sketching outside. Specifically, the support cavity is provided to fix the position and store the bracket. At the same time, the multifunctional assembly of the sketching chair is realized in a modular manner, thereby improving the practicality of the sketching chair.

[0030] Example 1

[0031] As shown in Fig. 1 to Fig. 6, a smart chair convenient for sketching outside comprises a seat 1 and a load-bearing part 2 for supporting the balance of the seat 1. One end of the load-bearing part 2 is connected to the seat 1 in abutting manner. Through the set abutting connection, the load-bearing part 2 can be separated from the seat 1 while supporting the seat 1, thereby compressing the storage space and facilitating carrying. Since the load-bearing part 2 is prone to tipping over due to the inconsistency of the force direction during the use of the support, a support part 3 is connected to the load-bearing part 2, and the load-bearing part 2 is formed into a whole through the support part 3, thereby ensuring that the force in any direction can be decomposed, and at the same time, the balance of the seat 1 and the load-bearing part 2 will not be affected. One side of the support part 3 is slidably connected to the seat 1, so that the support part 3 is used to support the seat 1. During the storage process, the seat 1 and the load-bearing part 2 will not be unable to be stored due to the position of the support part 3.

[0032] In the process of sketching outside, it is necessary to carry the sketching chair and the drawing board and the bracket supporting the drawing board at the same time. When the bracket is in use, the sketching chair and the bracket are separated, so the bracket is easy to fall down under the action of external force during use, thereby affecting the sketching. Therefore, a bracket cavity 6 for storing the bracket is opened on the chair 1, so that the bracket is connected to the body of the chair 1, which is convenient to carry and improves the stability of the bracket;

[0033] In order to facilitate the load-bearing part 2 to effectively support the seat 1, in this solution, the load-bearing part 2 includes four support legs 22, and two adjacent support legs 22 are connected by the support part 3. It should be noted that when two adjacent support legs 22 are shrunk and merged, the structure of the support part 3 can also be shrunk in space. Without affecting the supporting capacity of the support leg 22, a plurality of storage cavities 2201 are opened on the support leg 22. In this solution, in order to facilitate the support legs 22 to fit each other during the storage process, and to facilitate the design of the storage cavity 2201, the shape of the support leg 22 is a cylinder or a cuboid, and the number of the storage cavities 2201 on the support leg 22 is less than or equal to 4, wherein each storage cavity 2201 is connected to a movable part 7 for storing paint, and when the movable part 7 is located in the storage cavity 2201, the outer portion of the movable part 7 is flush with the outer end surface of the support leg 22, which does not affect the appearance of the support leg 22 and does not cause the movable part 7 to move. The movable part 7 is provided to deform the paint box and paint bucket that are originally required to be carried, so as to reduce the number of items to be carried when sketching.

[0034] As a further improvement of the present invention, in order to facilitate the opening of the movable part 7 and the use of the pigment in the movable part 7, and to improve the convenience of using the pigment, the movable part 7 includes a plurality of rotating plates 73, wherein the number of the rotating plates 73 is uniformly set according to the size of the barrel 72 and the length of the storage chamber 2201, and the number of the rotating plates 73 is always greater than or equal to 1. In this embodiment, the number of the rotating plates 73 is preferably 4, and a telescopic component is provided in a rotatable connection between two adjacent rotating plates 73, and when the telescopic component is in a shortened state, it can be stored between the two rotating plates 73, that is, when the rotating plate 73 is not moved out of the storage chamber 2201, the two adjacent rotating plates 73 in one storage chamber 2201 are connected to each other in abutment, and at the same time, the telescopic component is obliquely connected between the two rotating plates 73, so that when the barrel is used, the two adjacent rotating plates 73 can move parallel to the ground. In this embodiment, the telescopic component is preferably a telescopic rod, so that relative movement can be better achieved while reducing the weight of the sketching chair. The rotating plates 73 The first connecting rod 71 and the second connecting rod 74 with telescopic functions are respectively connected to the end close to the seat 1. The first connecting rod 71 and the second connecting rod 74 are arranged along the length direction on the rotating plate 73, and the first connecting rod 71 is close to the side of the seat 1, and the second connecting rod 74 is far away from the seat 1. It should be noted that in order to ensure that the rotating angle of the rotating plate 73 is large enough for the sketcher to put his hand in, the structure of the first connecting rod 71 and the second connecting rod 74 is set to a telescopic structure, that is, during the rotation of the rotating plate 73, the first connecting rod 71 and the second connecting rod 74 perform corresponding stretching movements, so that the distance between the rotating plate 73 and the storage chamber 2201 is large, which is convenient for use. The ends of the rotating plates 73 close to the storage chamber 2201 are respectively fixed with barrels 72 for storing paint. When not in use, the barrels 72 abut against each other between the storage chambers 2201, that is, one end of the barrel 72 abuts against the bottom of another barrel 72, thereby realizing the barrel 72. The purpose of sealing the pigment inside is to avoid leakage of the pigment inside the barrel when the sketching chair is moved. At the same time, the barrels 72 can also be closed individually, that is, the open end of each barrel 72 is manually closed, so as to achieve the purpose of closing the barrel 72.

[0035] In order to fully utilize the storage chamber 2201 and reduce the number of additional tools for holding paintbrushes, a pen holder 7301 is provided in at least one of the storage chambers 2201 , wherein the pen holder 7301 is connected to the rotating plate 73 .

[0036] As a further improvement of the present invention, the chair 1 includes a seat 11, and a backrest 13 is rotatably provided at one end of the seat 11 away from the load-bearing part 2, and a connecting part 12 is fixedly provided between the seat 11 and the backrest 13. The connecting part 12 is provided to realize the connection between the seat 11 and the backrest 13. At the same time, when the sketching chair is folded, the backrest 13 can also be folded through the connecting part 12, so that the backrest 13 and the seat 11 are in a parallel state, which is convenient for storage and movement. It should be noted that in this scheme, the structure of the connecting part 12 is equivalent to a hinge structure, and the connecting part 12 can make the backrest 13 folded on the seat 11, and there is a gap between the backrest 13 and the seat 11, wherein the gap is generated after folding, so that the drawing board that needs to be carried during the sketching process can be placed therein, thereby reducing the space for carrying equipment.

[0037] As a further improvement of the present invention, the support portion 3 includes two hinged rods 31, and the two ends of the two hinged rods 31 distributed along the length direction are respectively rotatably connected to the support legs 22. When the support legs 22 are opened, the two hinged rods 31 form a right angle to support the support legs 22. When the support legs 22 are retracted, the two hinged rods 31 are driven to rotate by moving the support legs 22, so that the two hinged rods 31 gradually collide with each other along the length direction, thereby realizing the storage of the hinged rods 31.

[0038] As a further improvement of the present invention, the support part 3 also includes a sliding rod 32, wherein one end of the sliding rod 32 abuts against the support leg 22, and when the support leg 22 moves, the sliding rod 32 does not separate from the support leg 22, so that the support leg 22 can form a whole with the seat 1 through the sliding rod 32, so that the sliding rod 32 can be moved by moving the support leg 22, thereby reducing the time for the sketching chair to be unfolded, and the end of the sliding rod 32 close to the seat 1 is slidably connected to the moving groove 51 on the seat 1, and one end of the sliding rod 32 is fixedly connected to the bracket in the bracket cavity 6, and the part where the sliding rod 32 is connected to the seat 1 can be folded, so that the seat 1 and the load-bearing part 2 can be distributed in parallel, which is easy to carry, and it should be noted that the premise when the sliding rod 32 controls the bracket is that one end of the supporting leg 22 abuts against one end of the seat surface 11, and when the supporting leg 22 flips out of contact with the seat surface 11 After the friction, the sliding rod 32 will not drive the bracket to expand when moving with the supporting leg 22.

[0039] As a further improvement of the present invention, in order to facilitate the rapid and accurate movement of the supporting legs 22 and the sliding rod 32, a limiting portion 5 for limiting the moving direction is provided at one end of the chair surface 11 close to the supporting portion 3. The limiting portion 5 includes a limiting groove 52 for the movement of the supporting legs 22. The limiting grooves 52 are cross-distributed on the chair surface 11. The limiting portion 5 also includes a moving groove 51 for the movement of the sliding rod 32, wherein the moving groove 51 is connected to the bracket cavity 6, and the limiting groove 52 is not connected to the moving groove 51. By setting the limiting portion 5, the position constraint of the device during movement is improved, thereby avoiding deviation of the moving position during the movement, which causes instability of the sketching chair.

[0040] As a further improvement of the present invention, in order to prevent the drawing board from falling off between the seat 11 and the seat back 13 and to ensure that the seat back 13 will not automatically unfold when vibrated during transportation, a plurality of fixing parts 4 are connected between the seat 11 and the seat back 13, wherein the number of the fixing parts 4 is greater than or equal to 1, and the fixing part 4 includes a fixing column 41 fixedly connected to the seat back 13 and a rotating plate 2 42 rotatably connected to the seat 11, wherein the rotating plate 2 42 can connect and clamp the fixing column 41, that is, after the seat back 13 and the seat 11 are distributed in parallel, the rotating plate 2 42 is rotated to be clamped and connected with the fixing column 41, so that the position between the seat back 13 and the seat 11 is stable, and the seat back will not automatically flip over during transportation. At the same time, the periphery of the drawing board is restrained to ensure that the drawing board will not move out of the sketching chair.

[0041] As a further improvement of the present invention, since the terrain conditions and flatness are different during the sketching process, in order to maintain the stability of the sketching chair during use, an adjustment component 21 is movably provided at one end of the support leg 22 away from the chair surface 11, and the adjustment component 21 includes an anti-slip gasket, a threaded rod and hard rubber, wherein the hard rubber is located between the anti-slip gasket and the threaded rod, and the threaded rod is threadedly connected to the support leg 22. In use, the length between the support legs 22 is greatly adjusted by the threaded rod, and after the adjustment is completed, the inclination angle of the sketching chair is adjusted by manually sitting on the sketching chair through the characteristics of the hard rubber, thereby maintaining the stability of the sketching chair.

[0042] It should be noted that, in this embodiment, in order to facilitate the storage of the sketching chair, the lengths of the support legs 22, the seat surface 11 and the chair back 13 are set to be the same, that is, after the three are folded, they form a regular shape.

[0043] Initially, the seat 11 and the seat back 13 are vertical, the four support legs 22 are away from each other, the rotating plate 42 and the fixed column 41 are separated, and the hinge rods 31 between two adjacent support legs 22 are vertically distributed, and the sliding rod 32 pops out the bracket in the support cavity 6.

[0044] When the sketching chair needs to be folded, the chair back 13 is first folded through the connecting portion 12, so that the load-bearing surfaces of the seat surface 11 and the chair back 13 are distributed in parallel, and then the rotating plate 42 is rotated so that one end of the rotating plate 42 is engaged with the fixing column 41, thereby fixing the distance between the seat surface 11 and the chair back 13.

[0045] When the position between the seat surface 11 and the seat back 13 forms a transport state, the positions of the four support legs 22 are moved along the limiting grooves 52 to the side close to each other, and during the movement of the support legs 22, since the sliding rods 32 will not be separated from the surfaces of the support legs 22, the movement of the support legs 22 drives the sliding rods 22 to move, and at this time, the support legs 22 always contact the end surfaces of the seat surface 11 during the movement, so that when the sliding rods 22 move along the moving grooves 51, the brackets extending out of the outside of the seat 1 can be retracted into the bracket cavity 6 for storage through the sliding rods 22, and during the movement of the support legs 22, the two hinged rods 31 can be driven to rotate, so that the two hinged rods 31 move from a vertical state to a state tending to overlap, thereby completing the storage of the load-bearing part 2 and the support part 3, and when two adjacent support legs 22 contact each other, the position of the load-bearing part 2 is rotated by the sliding rods 32, so that the support legs 22 One end extending in the length direction is parallel to the seat surface 11 .

[0046] At the same time, since the folded support leg 22 no longer contacts the seat surface 11, in order to ensure that the shape of the folded sketching chair is a regular pattern, which is convenient for carrying, the support leg 22 drives the sliding rod 32 to move along the moving groove 51, and finally a regular pattern is formed between the support leg 22, the seat surface 11 and the chair back 13, so as to facilitate carrying. After the sketching chair is folded, the drawing board is placed in the gap between the chair back 13 and the seat surface 11 for transportation, reducing the number of carrying tools.

[0047] When the sketching chair is moved to the sketching destination, the sketching chair is unfolded in the reverse order of the above sequence, so as to adjust the position of the adjustment component 21 according to the terrain of the sketching destination, so that the sketching chair can maintain a balanced state regardless of any terrain conditions.

[0048] Then, the rotating plate 73 is opened, so that the first connecting rod 71 and the second connecting rod 74 are stretched, so that the rotating plate 73 is distributed at an acute angle between the supporting legs 22, thereby ensuring that the opening space of the rotating plate 73 is sufficient for the user to use the barrel 72 and the pen holder 7301 on the rotating plate 73. At the same time, in order to further facilitate the use of the barrel 72, the rotating plate 73 is stretched in a direction parallel to the ground to stretch the telescopic assembly, so that the barrel 72 on the rotating plate 73 is distributed in a stepped manner, which is convenient for the use of paint.

[0049] Example 2

[0050] Based on the above-mentioned embodiment 1, although the multifunctional use of the sketching chair and the reduction of the number of items to be carried when sketching are solved, at the same time, when the sketching chair is unfolded or stored, it needs to be manually retracted, which wastes a lot of time.

[0051] Furthermore, a control center and a storage battery are arranged on the seat surface 11, an electromagnetic rotation deflection device is arranged on the connecting part 12 and the sliding rod 32, and an elastic reset device is arranged in the moving groove 51, and an electromagnetic guide rail is arranged in the limiting groove 52, and one end of the electromagnetic guide rail close to the support leg 22 is in conflict with the support leg 22.

[0052] Therefore, when the control center receives the storage instruction, the control center controls the connection part 12 so that the chair back 13 and the seat 11 are stored, and at the same time controls the electromagnetic guide rail to retract and move the support leg 22. At the same time, when the support leg 22 is retracted, the sliding rod 32 is used to complete the electromagnetic flipping and movement, so that the sketching chair is restored to the convenient carrying form in Example 1.

[0053] At the same time, in order to facilitate the adjustment component 21 to adapt to different terrains, a pressure sensor is set at one end of the adjustment component 21 close to the ground. When the sketching chair is in use, due to the different terrains, when the pressure sensor in the adjustment component 21 is subjected to different pressures, the adjustment component 21 is adjusted so that the pressures borne by the four supporting legs 22 on the sketching chair are the same, ensuring the stability of the sketching chair when in use.

[0054] The above are only preferred embodiments of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the method of the present invention. These improvements and supplements should also be regarded as the scope of protection of the present invention.
