Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to an automotive seat with a heating function. Background Technology

[0002] Car seats are mainly composed of a frame, foam, and cover. The assembly of a car seat is completed by fixing the foam to the frame and then covering it with the cover.

[0003] For example, Chinese patent document CN222388036U discloses an emergency response car seat rapid heating and emergency massage device, which belongs to the field of car seat technology. It includes: a seat cover and two mounting frames; a heating resistance wire, which is set on one side of the upper end of the seat cover; the two mounting frames are rotatably connected and each has a drive shaft inside; the two drive shafts are connected by a coupling.

[0004] In the above technical solution, the positions of multiple massage heads can be flexibly adjusted by the drive shaft and multiple threaded rods set in the two mounting frames, and a heating tube is set in the seat cushion to heat the seat cushion and improve the comfort of sitting in the chair.

[0005] However, in actual use, it was found that the heating element is usually installed in the mounting groove in the foam of the seat cushion. Therefore, when the user adjusts the sitting posture, the foam will be squeezed, and the resulting elasticity can easily pop the heating element out of the mounting groove or cause the heating element to shift, resulting in the seat surface not being flat enough and affecting the comfort of sitting in the chair. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a car seat with heating function, which can effectively limit the heat-conducting copper pipe and ensure the comfort of the seat.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a car seat with a heating function, comprising a seat body, the surface of which is covered with a cover, an installation groove on the seat body, a heat-conducting copper pipe disposed within the installation groove, a connecting pipe connected to the tail end of the heat-conducting copper pipe, a fan disposed on the outer side of the seat body, one end of the connecting pipe extending to the outside of the seat body and connected to the air outlet of the fan, a claw engaging the outer periphery of the heating copper pipe, the claw clamping the heat-conducting copper pipe to constrain its radial direction, a locking block at the bottom of the claw, an opening at the bottom of the installation groove, a locking seat below the installation groove, the locking seat and the locking block cooperating to constrain the axial direction of the heat-conducting copper pipe.

[0008] The present invention is further configured such that: the card holder is provided with a protruding frame and a base, the frame is opposite to the opening, the frame is provided with through guide holes on both sides, a steel ball is provided in the guide hole, a top pressure spring is provided between the steel ball and the base, and the card block is provided with a card groove adapted to the steel ball, so that the steel ball can be inserted into the card groove to form a limiting fit between the two.

[0009] The present invention is further configured such that: a sliding groove is provided in the card block, a driving block is provided in the sliding groove, and pushing blocks are provided on both sides of the driving block. The pushing blocks are opposite to the card groove, and a reset spring is provided between the pushing blocks and the inner wall of the card block. The driving block pushes the pushing blocks out of the sliding groove by pressing down, and the reset spring is used to drive the pushing blocks to reset so that the pushing blocks retract into the sliding groove.

[0010] The present invention is further configured such that: one side surface of the card block is provided with a through groove communicating with the slide groove, and a lever is fixed on the surface of the driving block, one end of the lever extending outward through the through groove.

[0011] The present invention is further configured such that: ventilation holes are provided on the mask, and the ventilation holes are multiple and spaced apart from each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because the heating copper tube is secured with claws and has a locking block at its bottom, and a locking seat is located below the mounting slot, the axial movement of the heating copper tube can be limited by the cooperation of the locking seat and the locking block. The claws, after engaging with the outer circumference of the heating copper tube, can also limit its radial movement. This ensures that the heating copper tube will not shift or tilt due to external forces after installation, thus ensuring that the seat cushion surface remains flat when adjusting the sitting posture, thereby ensuring the comfort of the chair.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 5 As shown, this utility model discloses a car seat with a heating function, including a seat body 1, the surface of which is covered with a cover. The seat body 1 consists of a backrest and a seat cushion, wherein the backrest and the seat cushion are respectively composed of a frame 100 and foam cotton bonded to their respective frames 100. An installation groove 2 is provided on the seat body 1, that is, the installation groove 2 is opened on the foam cotton of the seat cushion. The installation groove 2 is coiled in a serpentine shape. A heat-conducting copper pipe 3 is provided in the installation groove 2. The tail end of the heat-conducting copper pipe 3 is connected to a connecting pipe 4. A fan 5 is provided on the outside of the seat body 1. One end of the connecting pipe 4 extends to the outside of the seat body 1 and is connected to the air outlet of the fan 5. The fan 5 introduces the generated hot air or cold air into the heat-conducting copper pipe 3 through the connecting pipe 4. The excellent heat conduction performance of the heat-conducting copper pipe 3 realizes the heating or cooling of the surface of the seat cushion. In addition, multiple ventilation holes 9 are further opened on the cover, which facilitate the circulation of the hot air or cold air generated by the fan 5 and increase the breathability.

[0022] In this embodiment, the outer periphery of the heating copper tube is secured with elastic claws 6. The heating copper tube is installed in the mounting groove 2 via the claws 6, meaning that the clamping part on the inner side of the claws 6 is tightly attached to the surface of the heat-conducting copper tube 3. This causes the claws 6 to deform and generate radial pressure on the heat-conducting copper tube 3, preventing radial displacement of the heat-conducting copper tube 3. The bottom of the claws 6 extends into an inverted conical block 7. An opening 21 is correspondingly opened at the bottom of the mounting groove 2. A mounting base 8 is fixed below the opening 21. The mounting base 8 is fixed to the frame 100 of the cushion by bolts or welding. The mounting base 8 has a protruding base 82 and a frame 81. Steel balls 83 are embedded in the guide holes 811 on both sides of the frame 81. A top pressure spring 84 is provided between the steel balls 83 and the base 82. The two ends of the top pressure spring 84 are connected to the steel balls 83 and the base 82, respectively. Under normal conditions, the steel balls 83 protrude from the guide holes 811 and enter the frame 81. When the card block 7 is inserted into the frame 81, the slot 71 on the side wall of the card block 7 can engage with the steel ball 83. The limiting effect of the steel ball 83 is used to fix the claw 6 axially, thus completing the axial fixation of the heat-conducting copper tube 3.

[0023] Furthermore, to facilitate the disassembly of the pawl 6, a sliding groove 72 is provided inside the pawl block 7. A drive block 73 is slidably installed in the sliding groove 72. The ends of the wedge-shaped push blocks 74 on both sides of the drive block 73 correspond to the positions of the slots 71. A return spring 75 is provided between the push blocks 74 and the inner wall of the sliding groove 72. Under normal conditions, the return spring 75 causes the push blocks 74 to retract into the sliding groove 72. When the drive block 73 is pressed, the push blocks 74 push outward and squeeze the steel ball 83 to disengage from the slots 71, thereby releasing the lock between the pawl block 7 and the pawl seat 8. At this time, the pawl 6 can be slid upward to disassemble the pawl 6. In addition, a lever 8 is fixed on the surface of the drive block 73. The lever 8 extends to the outside through the through groove 76 provided in the side wall of the pawl block 7. The movement of the drive block 73 can be controlled by moving the lever 8. During actual assembly, the heat-conducting copper tube 3 is first embedded into the mounting groove 2 and clamped and fixed by the claw 6. Then, the locking block 7 of the claw 6 is aligned with the opening 21 and pressed down so that the steel ball 83 is inserted into the slot 71 to complete the axial locking. When disassembling, the lever 8 is moved to drive the push block 74 to push open the steel ball 83, so that the claw 6 and the heat-conducting copper tube 3 can be taken out as a whole for maintenance.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
