Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to an aesthetically pleasing backrest heat dissipation device and a seat. Background Art

[0002] Whether it is for work, study or entertainment, people's lives cannot be separated from chairs. However, when sitting for a long time, the user's back will inevitably feel stuffy and even sweat when the backrest is pressed against the backrest. Even if a mesh backrest with good breathability is used, it is difficult to bring a cool experience to the user's back in hot weather just by the breathability of the mesh.

[0003] In order to solve the above problems, the existing patent provides a lumbar support with a fan (application number: CN201120018997.5). By arranging a fan in the lumbar support of the seat, the wind generated by the fan is discharged through the mesh on the front side of the lumbar support, thereby providing heat dissipation for the user's back and bringing a cooler and more comfortable experience.

[0004] However, in today's market, users' demands for products are not only limited to the functional level, but also increasingly demand for product appearance. Especially for the field of e-sports, the above-mentioned lumbar support with a fan can solve the problem of e-sports players sitting for a long time in the summer. In addition, in terms of the display and response of the e-sports style, most e-sports chairs focus on the appearance and outline, and some e-sports chairs create an e-sports atmosphere through the installation of light strips; but some e-sports chairs with lighting effects set the light strips in the back cushion of the chair back. Since the cushion is made of sponge material, the light strips will generate heat when they emit light, so there are hidden safety risks; secondly, the light strips are in close contact with the sponge material, and the sponge material is easily deformed by the user's squeezing, which causes the light strips to deform and pull, making the light strips very easy to damage and malfunction. Summary of the invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide an aesthetically pleasing heat dissipation device and seat. By installing the light-emitting component on a rear cover plate made of plastic, not only can the user be provided with an ambient lighting effect, but also during use, although the light-emitting component will generate heat, the rear cover plate is made of plastic and has better safety. Moreover, the rear cover plate is made of a harder material and is not easily deformed after being squeezed by the user, so that the light-emitting component in the installation groove is not easily deformed or pulled, which has a protective effect on the light-emitting component and extends its service life.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0030] Please refer to the attached Figure 1-9The embodiment of the present application provides an aesthetically pleasing heat dissipation device, including a lumbar support base 1, the lumbar support base 1 includes a front cover plate 110 and a rear cover plate 120 spliced ​​together front and back, at least the front cover plate 110 has a ventilation function, and at least the rear cover plate 120 is made of plastic, an interlayer is formed between the front cover plate 110 and the rear cover plate 120, the interlayer forms an accommodating cavity 130 for installing a fan, at least one mounting portion 131 is arranged in the accommodating cavity 130, and the mounting portion 131 is configured to install a fan; the area on the rear cover plate 120 facing the mounting portion 131 is a ventilation portion 121, and a circular mounting groove 122 is arranged in a recessed manner on the circumferential side of the ventilation portion 121, and a light-emitting component is detachably arranged in the mounting groove 122, and the light-emitting component is configured to create an ambient light effect.

[0031] In the present embodiment, by installing a fan in the mounting portion 131 inside the lumbar support base 1, the air generated by the fan can be discharged through the ventilated front cover plate 110 to provide heat dissipation for the user's back; and, by installing the light-emitting component on the rear cover plate 120 made of plastic material, not only can the user be provided with an ambient light effect, but also during use, the light-emitting component will generate heat, and the rear cover plate 120 will not easily catch fire after being heated, so the safety is better; moreover, the rear cover plate 120 is made of a harder material and is not easily deformed after being squeezed by the user, so that the light-emitting component in the mounting groove 122 is not easily deformed or pulled, which has a protective effect on the light-emitting component and prolongs its service life.

[0032] Preferably, the ventilation portion 121 is a hollow plate-like structure with a plurality of ventilation holes 125, and the plurality of ventilation holes 125 are combined to form a fan shape, which can not only assist the heat dissipation of the heat dissipation device, but also clearly remind the user that the user is facing the fan in the heat dissipation device through the fan-shaped ventilation holes 125, which has good interactivity. Of course, in other embodiments of the present application, the ventilation portion 121 can also be a hollow circular hole on the rear cover plate 110, or a grid-shaped baffle, etc.

[0033] Among them, preferably, the front cover plate 110 is a hollow plastic part with a plurality of mesh holes, so that the overall strength of the lumbar support base 1 is better. When the front cover plate 110 is under pressure, the front cover plate 110 is not easy to deform, thereby avoiding the shrinkage of the accommodating cavity 130 and causing the fan to be squeezed and damaged.

[0034] In some embodiments of the present application, the light-emitting component includes a light strip and a light-transmitting member 140 . The light strip is laid in the mounting groove 122 . The light-transmitting member 140 covers the mounting groove 122 . The light-transmitting member 140 is configured to make the light of the light strip softer and more evenly distributed.

[0035] In this embodiment, the mounting groove 122 is covered by the light-transmitting member 140, so that the light strip is not easy to fall out of the mounting groove 122, thereby improving stability; the light-transmitting member 140 can not only evenly disperse the light of the light strip, but also the color of the light emitted by the light strip is affected by the color of the light-transmitting member 140. During manufacturing, the manufacturer only needs to replace the light-transmitting member 140 to change the color of the atmosphere light to meet the needs of different customers.

[0036] Among them, preferably, the light-transmitting member 140 is made of PC material, which has high transparency and free dyeing properties. It not only has good light transmission effect, but also is easy to dye during the manufacturing process to provide various colors of ambient light effects.

[0037] Preferably, when the light-transmitting member 140 is covered in the mounting groove 122 , the outer surface of the light-transmitting member 140 is flush with the rear cover plate 120 , thereby making the heat dissipation device more integrated and beautiful in appearance.

[0038] In some embodiments of the present application, a plurality of positioning protrusions 123 are provided on the side walls of the mounting groove 122 . When the light strip is laid in the mounting groove 122 , the top end of the light strip is abutted by the positioning protrusions 123 and is stably clamped in the mounting groove 122 .

[0039] In this embodiment, the light strip is fixed by providing a positioning protrusion 123 on the installation groove 122 , which effectively prevents the light strip from detaching from the installation groove 122 after installation, thereby improving stability.

[0040] The width of the positioning protrusion 123 is smaller than the width of the mounting groove 122 , so that when the light strip is installed, it can be inserted and fixed in the gap between the positioning protrusion 123 and the mounting groove 122 , making the installation operation of the light strip relatively simple.

[0041] In some embodiments of the present application, a plurality of latches 141 are disposed at the bottom end of the light-transmitting member 140, and a plurality of plug holes 124 are provided on the mounting groove 122. When the light-transmitting member 140 is covered on the mounting groove 122, the latches 141 and the plug holes 124 are plugged in and matched. Connecting the light-transmitting member 140 and the mounting groove 122 by plugging in and matching not only makes the connection strength between the light-transmitting member 140 and the mounting groove 122 more reliable after being covered, but also makes the installation and disassembly operations between the two more convenient.

[0042] In some embodiments of the present application, two left-right symmetrical mounting portions 131 are disposed in the accommodating cavity 130 .

[0043] In this embodiment, by providing mounting portions 131 on both the left and right sides of the accommodating cavity 130, that is, providing two fans on the heat dissipation device, the two fans work together to dissipate heat, which can greatly improve the heat dissipation performance of the heat dissipation device; at the same time, the rear side of the rear cover plate 120 is also connected to two left-right symmetrical light-emitting components, so that in terms of appearance, the ambient light effect of the heat dissipation device is more coordinated and more aesthetically pleasing.

[0044] Of course, in other embodiments of the present application, the number of the mounting portions 131 in the accommodating cavity 130 may also be one, three, or the like.

[0045] In some embodiments of the present application, a mounting ring 132 with an annular structure is disposed in the accommodating cavity 130 , and a hollow portion of the mounting ring 132 forms a mounting portion 131 .

[0046] In this embodiment, by providing a mounting ring 132 with an annular structure, the fan is installed in the hollow portion of the mounting ring 132 , so that after the fan is installed, it is limited by the mounting ring 132 and is not prone to shaking, thereby improving stability.

[0047] Among them, threaded parts 133 extend around the mounting ring 132, and each threaded part 133 is provided with a hole; after the mounting ring 132 and the front cover plate 110 are connected, screws can be screwed into the holes on the threaded parts 133 to screw and fix the mounting ring 132 and the front cover plate 110, which not only makes the strength of the mounting ring 132 reliable after connection, but also makes the installation and disassembly operations of the mounting ring 132 relatively simple.

[0048] In some embodiments of the present application, the front end surface of the front cover plate 110 is further connected to a cushion 111 . The cushion 111 is made of a flexible material and has a plurality of mesh holes hollowed out thereon.

[0049] In this embodiment, the heat dissipation device supports the user's back through a relatively soft cushion 111, so that the heat dissipation device can also be used as a lumbar support, and the use experience is relatively comfortable; and the cushion 111 is hollowed out and has a plurality of mesh holes, so that the cushion 111 has better air permeability and will not affect the heat dissipation effect of the heat dissipation device.

[0050] Preferably, the cushion 111 is made of sponge material, which is not only soft and comfortable to use, but also breathable, and will not block the wind blown by the fan, and has little impact on the heat dissipation device. Of course, in other embodiments of the present application, the cushion 111 can also be made of rubber, elastic mesh, etc.

[0051] In some embodiments of the present application, a circuit control device is provided on the lumbar support base 1, and the circuit control device includes a light strip switch 126 and a fan switch 127 provided on the rear cover plate 120, the light strip switch 126 is configured to turn on or off the light-emitting component, and the fan switch 127 is configured to turn on or off the fan.

[0052] In this embodiment, by turning on the fan switch 127 and the light strip switch 126, the user can use the fan or the light strip separately according to the usage environment, which is more practical. For example, when the weather is cool and no heat dissipation is needed, the fan switch 127 is turned off, and the light strip still provides ambient lighting effects for the user; or when the ambient light is too bright, the light strip switch 126 is turned off, and the fan still rotates to provide heat dissipation for the user.

[0053] The embodiment of the present application also provides a seat, including a back support 2, a backrest 3 and an aesthetically pleasing heat dissipation device, wherein the lumbar support base 1 is arranged between the back support 2 and the backrest 3; the upper and lower ends of the rear cover plate 120 respectively extend backward to form an upper connecting portion 150 and a lower connecting portion 152, and the upper connecting portion 150 and the lower connecting portion 152 are both provided with connecting holes 151, and the lumbar support base 1 is threadedly connected to the back support 2 through the connecting hole 151.

[0054] In this embodiment, the lumbar support base 1 is screwed to the back support 2 via the upper connecting portion 150 and the lower connecting portion 152, which not only makes the connection strength between the lumbar support base 1 and the back support 2 more reliable, but also makes the installation and disassembly operations of the lumbar support base 1 easier.

[0055] In some embodiments of the present application, a support portion 160 extends upward from the upper end of the upper connecting portion 150, and a gap is left between the support portion 160 and the lower connecting portion 152, the gap forming a power supply portion 161, the power supply portion 161 is configured to install a power supply, and an elastic member 162 is provided on the rear side of the rear cover plate 120, the elastic member 162 is configured to clamp the power supply between the rear cover plate 120 and the back bracket 2.

[0056] In this embodiment, a power supply portion 161 is reserved between the lumbar support base 1 and the back support 2 to install an external power source such as a power bank, so that the seat only needs to be powered by replacing the power supply, and there is no need to connect the power supply to the socket through wires. The use of the seat is not restricted and it is more convenient.

[0057] Among them, the back support 2 is a hollow structure, and various lines on the seat can be hidden through the back support 2, making the seat look neater and more beautiful.
