[0027] The above and other technical features and functions of this application are described in detail below with reference to the attached Figures 1 to 7 The embodiments are described in detail.

[0028] Embodiment 1:

[0029] Here, refer to Figure 1 Before explaining the window glass regulator, a vehicle door including the window glass regulator will be explained. The vehicle door is provided in a car (vehicle). Figure 1 As shown, the vehicle door includes: a door body; a vehicle window glass supported so as to be able to be raised and lowered along a predetermined path; and a window glass regulator attached to the door body to raise and lower the window glass.

[0030] The door body has a storage portion for storing the window glass and a door window frame disposed above the storage portion. The storage portion has an inner panel on the inside of the vehicle compartment as a door panel and an outer panel (not shown) on the outside of the vehicle compartment, and a door internal space is formed between the inner panel and the outer panel. Figure 1As shown, the window regulator is mounted so as to be inclined toward the rear side in the vehicle front-rear direction relative to the door body.

[0031] The PCB-type excitation glass regulator comprises: a mounting plate 5, which has a body arranged along the lifting direction of the window glass. As a new type of linear motor technology, the PCB-type excitation linear motor provides a fast and precise power solution, greatly improving production efficiency and reliability. This type of motor combines the advantages of permanent magnet materials and circuit board (PCB) technology. The PCB-type excitation linear motor mainly generates a magnetic field through coils arranged on the PCB board. When the current passes through these coils, the generated magnetic field interacts with the permanent magnets to achieve linear motion. The operation of the motor is based on the Lorentz force principle, that is, when the current flows in the magnetic field, it will be subjected to a force perpendicular to the direction of the current and the magnetic field, and this force drives the motor to move linearly. Compared with traditional linear motors, the coils and permanent magnets of the PCB-type excitation linear motor are arranged on a plane. Such a design not only simplifies the manufacturing process, but also helps to improve the integration and compactness of the motor. The modular design of the motor allows for rapid replacement and upgrading, greatly improving maintenance efficiency and flexibility. Users can quickly replace damaged parts or update to higher-specification modules as needed.

[0032] In this embodiment, the PCB excitation linear motor includes a mover and a stator. The stator is arranged along the lifting direction of the window glass 1 and fixed on the mounting plate 5. The mover can move relative to the stator under the action of excitation. The stator has a accommodating cavity. The inner walls of the magnetic steel skeletons 6 arranged relatively in the length direction of the stator are provided with magnetic steel 7 arrays. The mover is a PCB winding 4. The PCB winding 4 includes a multi-layer PCB board. There are through holes between the multi-layer PCB boards for interconnecting the windings. The turns between the windings of each layer of the PCB boards are connected in series or in parallel through the through holes, such as Figure 6 As shown in FIG. 7 , the PCB winding 4 is electrically connected to the battery 3 , wherein the battery 3 is a storage battery, which is mounted on the mounting body in this embodiment.

[0033] In this embodiment, the PCB winding 4 is essentially a planar transformer. The winding of the planar transformer is realized by using the spiral traces on the PCB. The middle of the PCB board is hollowed out for installing the magnetic core. The layers of the PCB board are insulated by plates. The magnetic core directly clamps the PCB in the middle and then fixes it with tape or clips. The height of the planar transformer has been effectively reduced, and the volume has been further saved. The PCB traces are flat, and the copper thickness is generally 1oz / 2oz. By calculation, when the frequency is less than 14MHZ, the skin depth of copper is less than half of the PCB copper thickness. Usually the switching power supply frequency is much lower than this value, so the skin effect of the planar transformer can be ignored. When the windings are connected in series, each layer of the printed circuit board is equipped with a row of through holes and the positions are aligned, but each layer of the winding only uses two of the through holes, thereby realizing the winding series connection. In low-voltage and high-current situations, the current capacity of the transformer can be improved by connecting the windings in parallel. Planar transformers generally use E-type, RM-type, EC, ETD and EER-type magnetic cores made of high-frequency power ferrite soft magnetic materials.

[0034] It also includes a mounting body 2, which is fixedly connected to the mover and the vehicle window glass is supported and fixed on the mounting body; wherein, the movement of the mover driven by the PCB-type excitation linear motor relative to the stator can guide the vehicle window glass to move along the stator in the lifting direction, thereby adjusting the glass lifting position.

[0035] Since the utility model adopts a PCB-type excitation linear motor, the coordination and installation of multiple components such as the collector, guide rail, magnetic reading head, magnetic scale, and electromagnetic lock can be omitted, which greatly reduces the production cost and can significantly reduce the size of the entire machine and the difficulty of installation, so that it can be used in occasions where the door space is limited.

[0036] Moreover, the PCB board is a multi-layer structure with circuit layers and insulation layers arranged alternately. The circuit layers are independent of each other and are easy to etch. Coils are etched on each circuit layer, and the coils on different circuit layers are electrically connected to form a coil unit, thereby increasing the thrust density of the motor.

[0037] Embodiment 2:

[0038] In addition to the contents of the aforementioned embodiments, the present embodiment further includes installing a PCB winding 4 in the middle position of the installation body 2, and providing sliders 8 on both sides of the installation body 2; installing a stator in the middle position of the installation plate 5 body, and providing a guide flange on at least one side of the guide rail 22, wherein the installation body slider and the guide flange of the guide rail are slidably matched.

[0039] like Figure 3 As shown, the mounting plate has a flat plate portion extending in the lifting direction; a right plate portion and a left plate portion, and has a side guide flange. The mounting plate can slide freely on the side guide flange using a slider.

[0040] Embodiment 3:

[0041] In addition to the contents of the aforementioned embodiments, the present embodiment includes the array of magnetic steels 7 respectively disposed on the inner wall of the first magnetic steel frame and the inner wall of the second magnetic steel frame, so that adjacent magnets in the magnet array are evenly spaced.

[0042] In this embodiment, the accommodating cavity of the stator has an installation space extending along the length direction; the magnetic pole pair composed of magnetic steel is installed in the installation space, the magnetic pole pair includes a first permanent magnet and a second permanent magnet arranged relatively in the height direction, there are multiple magnetic pole pairs, and they are arranged at equal intervals along the length direction; the PCB board is placed between the first permanent magnet and the second permanent magnet; wherein the PCB board is a multi-layer structure with circuit layers and insulating layers arranged alternately, each circuit layer is etched with a coil, and the coils on different circuit layers are electrically connected to form a coil unit.

[0043] Embodiment 4:

[0044] In addition to the contents of the aforementioned embodiments, the present embodiment includes guide protrusions 9 on the upper surfaces of the first magnetic steel frame and the second magnetic steel frame, and the guide protrusions 9 cooperate with the two guide grooves on the lower surface of the mounting body 2 .

[0045] In order to further stabilize the operation of the mounting body 2, without adding additional guide members, the guide protrusions 9 on the upper surfaces of the first magnetic steel skeleton and the second magnetic steel skeleton are used as guide members, and the two guide grooves on the lower surface of the mounting body 2 are used to cooperate therewith, thereby achieving the purpose of further enhancing the stabilization effect.

[0046] The above description is only for illustrating the present application. It should be understood that the present application is not limited to the above embodiments, and various variations that are consistent with the concept of the present application are within the protection scope of the present application.
