[0040] Reference Figures 1-5 A controller for heating car seats includes a housing body, a PCB assembly, a cover body, a flexible positioning mechanism, a cable 2, and a connector 4.

[0041] The PCB assembly is fixed to the bottom of the inner part of the box body, which can effectively enclose and protect the PCB assembly. The modules on the PCB assembly can be integrated for effective heating control. The lid body is slidably installed on the inner side of the upper part of the box body. The lid body and the box body are installed by sliding splicing, making installation more convenient. An elastic positioning mechanism is installed between the rear end connection of the box body and the lid body. After sliding installation, the box body and the lid body can be effectively positioned by the elastic positioning mechanism, thus playing a positioning role during assembly and effectively preventing the box body and the lid body from falling off. Cable 2 is installed and connected to the rear end of the box body and is electrically connected to the PCB assembly. Cable 2 can transmit current to the PCB assembly. Connector 4 is installed and connected to the front end of the box body and is electrically connected to the PCB assembly. The PCB assembly can transmit controlled current to connector 4, which can then be connected to an external car seat heating component for power supply and heating.

[0042] Reference Figures 1-4 The elastic positioning mechanism includes a positioning inclined post 51, which can be inserted for positioning. The upper end of the positioning inclined post 51 has an abutting inclined surface 5, so that when the lid body slides and closes through the lid shell 1, the lid shell 1 contacts the abutting inclined surface 5, thus facilitating the sliding contact of the positioning inclined post 51 for downward pressure. The lower end of the positioning inclined post 51 is fixedly connected to an abutting spring 52, which causes the abutting spring 52 to deform. The lower end of the abutting spring 52 is fixed to the box shell 3, and the abutting spring 52 can... The box body shell 3 deforms, and then the positioning oblique post 51 can be positioned and moved down on the box body shell 3. The positioning oblique post 51 is inserted into the oblique post insertion hole 12 of the box cover shell 1. After the box cover shell 1 moves to the splicing position, the positioning oblique post 51 is restored by the elastic restoration of the contact spring 52. Then the positioning oblique post 51 can be effectively fixed in the oblique post insertion hole 12 of the box cover shell 1, so as to play the role of insertion and positioning, thereby preventing the box cover shell 1 from moving backward and opening. This makes the fixing more stable, firm and tight.

[0043] Reference Figures 1-3 The box body includes a box shell 3. The box shell 3 has an assembly cavity 33 inside, which facilitates the installation of the PCB assembly. The upper two sides of the box shell 3 have slide mounting grooves 31, which allow the T-shaped slides 7 of the box cover body to be spliced ​​and installed accordingly. The front inner side of the box shell 3 is fixed with a positioning insert plate 32, which allows the splicing sleeve holes 13 of the box cover body to be spliced ​​and assembled accordingly. The box cover body is slidably installed on the box shell 3 through the slide mounting grooves 31, which allows it to be slidably installed accordingly.

[0044] The inner rear end of the outer shell 3 is provided with a mounting hole corresponding to the abutment spring 52, so that the abutment spring 52 can be installed, positioned and deformed accordingly.

[0045] The lid body includes a lid shell 1. The rear ends of the lid shell 1 have two inclined pin holes 12. An elastic positioning mechanism is installed on the lid shell 1 through the inclined pin holes 12, allowing the elastic positioning mechanism to be inserted and positioned accordingly. A rear baffle 11 is fixedly connected to the rear end of the lid shell 1, which acts as a rear blocking element during assembly. T-shaped slide bars 7 are fixedly connected to the lower ends of the lid shell 1. The lid shell 1 slides on the slide bar mounting groove 31 of the lid shell 3 through the T-shaped slide bars 7, facilitating sliding installation and making installation more convenient and efficient. A splicing sleeve hole 13 is opened on the inner side of the front end of the lid shell 1. The lid shell 1 is fitted onto the positioning insert plate 32 through the splicing sleeve hole 13, allowing for effective splicing after sliding installation, thus making installation more stable.

[0046] The connection between the outer shell of the lid 1 and the outer shell of the box body 3 is aligned so that there will be no obstruction during use.

[0047] Reference Figure 1 , Figure 2 and Figure 5 The PCB assembly includes a PCB board body 6. Mounting posts 8 are installed at the four corners of the lower end of the PCB board body 6. The mounting posts 8 are fixed to the bottom of the inner part of the outer shell 3, so that the mounting posts 8 can support the PCB board body 6 for placement. The PCB board body 6 and the mounting posts 8 are connected by assembly screws 81, so that they can be assembled and connected accordingly. The PCB board body 6 is fitted into the assembly cavity 33 of the outer shell 3, so that it can be positioned and placed.

[0048] Working principle: During use, cable 2 can transmit current to the PCB assembly, and the PCB assembly can transmit the controlled current to the connector 4. Through the connector 4, it can be connected to the external car seat heating component to provide power and heating. The cover body and the box body are installed by sliding splicing, which makes the installation more convenient. The elastic positioning mechanism is installed between the rear end connection of the box body and the cover body. After the box body and the cover body are slidably installed, the elastic positioning mechanism can effectively position them, thereby playing a positioning role during assembly and effectively preventing the box body and the cover body from falling off. This makes the assembly more tight and firm.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
