[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Depend on Figures 1 to 5 The present invention includes a vehicle roof 1 and a heater body 2. The heater body 2 is equipped with a temperature sensor (such as a thermistor or thermocouple) and a temperature controller. When the temperature reaches a preset limit, the power supply is automatically cut off or the power is adjusted to avoid damage, fire or safety accidents caused by overheating.

[0019] The vehicle roof 1 has an embedded groove 3 that matches the heater body 2. The vehicle roof 1 has a return air vent 26 that communicates with the embedded groove 3. The top of the embedded groove 3 has a winding groove 4. A winding shaft 5 is rotatably installed inside the winding groove 4. A first motor 6 connected to one end of the winding shaft 5 is installed inside the vehicle roof 1. Two winding wheels 7 are fixedly installed on the surface of the winding shaft 5. A thin suspension cable 8 is wound around the surface of both winding wheels 7. One end of the thin suspension cable 8 is fixedly connected to the winding wheel 7, and a hook 9 is fixedly installed on the other end of the thin suspension cable 8. Two lifting rings 10 are fixedly installed on the top of the heater body 2. The two hooks 9 are hooked and connected to the two lifting rings 10 respectively.

[0020] Both ends of the embedded groove 3 are provided with fixed slots 11, and both ends of the heater body 2 are provided with grooves 12 aligned with the fixed slots 11. Right-angled trapezoidal plugs 13 are symmetrically installed inside the two grooves 12. The two right-angled trapezoidal plugs 13 are movably inserted into the two fixed slots 11 respectively. The middle part of the heater body 2 is provided with an inner mounting groove 14. A dual-output shaft motor 15 is installed inside the inner mounting groove 14. The two output ends of the dual-output shaft motor 15 are respectively connected to the two right-angled trapezoidal plugs 13 for transmission.

[0021] The two ends of the mounting inner groove 14 are connected to the two grooves 12, and both ends of the mounting inner groove 14 are provided with rectangular frames 16. The ends of the two rectangular frames 16 near the grooves 12 are movably inserted with inverted T-shaped adjustment plates 17. One end of the inverted T-shaped adjustment plate 17 extends into the interior of the groove 12 and is fixedly connected with a right-angled trapezoidal insert 13. Both ends of the mounting inner groove 14 are fixedly installed with fixing plates 18 that penetrate the rectangular frames 16. One side of the fixing plate 18 is fixedly connected to the inverted T-shaped adjustment plate 17 with a compression spring 19, so that the heater body 2 can be automatically installed inside the embedded groove 3 during the hoisting process.

[0022] Specifically, the heater body 2 is suspended by hooking two hooks 9 and two rings 10. Then, by starting the first motor 6, the winding shaft 5 drives the two winding wheels 7 to rotate and wind up the thin sling 8. As the thin sling 8 is wound up, it moves the heater body 2 upward through the hooks 9 and rings 10. During the upward movement of the heater body 2, it is manually aligned with the embedding groove 3. As the heater body 2 moves into the embedding groove 3, the two right-angled trapezoidal inserts 13 come into contact with the vehicle roof 1 and are compressed. The right-angled trapezoidal inserts 13 are compressed by the compression spring 19 through the inverted T-shaped adjusting plate 17. When the groove 12 and the right-angled trapezoidal inserts 13 are aligned with the fixing slot 11, the elastic restoring force of the compression spring 19 will cause the right-angled trapezoidal inserts 13 to be inserted into the fixing slot 11, thus making the heater body 2 stably installed inside the embedding groove 3. At this time, it cannot be disassembled by external force.

[0023] Two rectangular frames 16 are each fixedly mounted with a sleeve 20 at the end away from the groove 12. Two output ends of the dual-shaft motor 15 are each fixedly mounted with a rotating shaft 21. The two rotating shafts 21 pass through the two sleeves 20 respectively and are rotatably connected to the fixed plate 18. The surfaces of the two rotating shafts 21 are each provided with a horizontal reset slide groove 22. The opposite ends of the two horizontal reset slide grooves 22 are each provided with an arc-shaped slide groove 23. A spiral slide groove 24 is provided between the arc-shaped slide groove 23 and the other end of the horizontal reset slide groove 22. The inside of the two sleeves 20 is fixedly mounted with a toggle pin 25 located inside the horizontal reset slide groove 22, so that the two right-angled trapezoidal inserts 13 can be moved and adjusted to disassemble the heater body 2.

[0024] Specifically, by starting the dual-output shaft motor 15, the two rotating shafts 21 rotate one revolution. The rotation of the two rotating shafts 21 will cause the horizontal reset slide 22, the arc slide 23 and the spiral slide 24 to rotate, thereby causing the actuating pin 25 to move to the spiral slide 24 and drive the sleeve 20, the rectangular frame 16, the inverted T-shaped adjusting plate 17 and the right-angled trapezoidal plug 13 to move, so that the right-angled trapezoidal plug 13 moves out of the fixed slot 11 and the inverted T-shaped adjusting plate 17 compresses the compression spring 19.

[0025] When the actuating pin 25 moves into the arc-shaped slide 23, the right-angled trapezoidal insert 13 has been moved out of the fixed slot 11. At this time, the heater body 2 is disassembled by unwinding the thin sling 8 and moving it down from the embedded slot 3. When the actuating pin 25 moves into the horizontal reset slide 22, the elastic restoring force of the compression spring 19 will cause the actuating pin 25, sleeve 20, rectangular frame 16, inverted T-shaped adjusting plate 17 and right-angled trapezoidal insert 13 to move and reset.

[0026] This temperature-controlled embedded heater features a lifting structure, which facilitates easy assembly and disassembly, enhancing safety. It also incorporates an automatic installation and electric disassembly mechanism, ensuring efficient installation while preventing unauthorized disassembly. Furthermore, the embedded heater boasts a simple design, ease of use, and reliable assembly and disassembly, meeting all performance requirements.
