[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. First of all, it should be noted that the directional terms such as up, down, left, right, front, back, inside, outside, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0024] In this application, unless otherwise clearly specified and limited, the term "fixed" and the like should be understood in a broad sense. For example, "fixed" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] Figure 1 The structure of the gear used in the window lifting and lowering driving device disclosed in this application is shown. Figure 1 It is clear that the gear 10 is composed of an inner ring 100, an outer ring 200 and a connecting structure 300. The inner ring 100 is provided with a first tooth portion 110. The outer ring 200 is coaxially arranged with the inner ring 100, and the outer ring 200 is provided with a second tooth portion 210. The connecting structure 300 is used to radially connect the inner ring 100 and the outer ring 200, so that the power received by the outer ring 200 is directly transmitted to the inner ring 100 in the radial direction, and the connecting structure 300 is made of plastic, such as polyoxymethylene (POM) and other materials and can be elastically deformed. It can be seen that when the gear 10 is impacted, the connecting structure 300 can absorb a certain impact energy, reduce vibration and play a buffering role, thereby extending the service life of the gear 10, and at the same time can prevent the parts matched with it, such as the worm gear mechanism, from getting stuck.

[0026] In such Figure 1In the illustrated embodiment, the connection structure 300 includes at least three ribs 310, which are of the same size and are evenly arranged circumferentially around the axis of the inner ring 100. Further, the contours of the at least three ribs 310 are spiral lines or arc curves. Specifically, when the contours of the at least three ribs 310 are arc curves, the arc curves can be designed to be S-shaped (refer to Figure 1 ). When the contour lines of the at least three ribs 310 are spiral lines, the spiral lines include Archimedean spiral lines, involute spiral lines or Fibonacci spiral lines (refer to Figure 2 )wait.

[0027] In such Figure 3 In the illustrated embodiment, the at least three ribs 310 are respectively provided with protrusions 311 extending along the radial direction of the inner ring 100 and protrusions 312 extending along the axial direction of the inner ring 100, thereby forming a three-dimensional structure. Specifically, the protrusions 311 include a first protrusion 311A ​​and a second protrusion 311B, wherein the first protrusion 311A ​​is fixedly connected to the inner ring 100, and the second protrusion 311B is fixedly connected to the outer ring 200, and the protrusion 312 is provided with a U-shaped cross-sectional shape and has a first end 312A and a second end 312B, and the first end 312A and the second end 312B are respectively fixedly connected to the first protrusion 311A ​​and the second protrusion 311B.

[0028] For the purpose of facilitating manufacturing, the connection structure 300 , the inner ring 100 , and the outer ring 200 may be manufactured in an integrally formed manner.

[0029] In addition, the present application also provides a window lift drive device, which is provided with the above-mentioned gear 10. The technical improvements and beneficial effects of the window lift drive device are the same as those of the gear 10, so the window lift drive device will not be described in detail.

[0030] It should be noted that the window lifting drive device may also include a worm gear mechanism (not shown) and an output mechanism (not shown), wherein the worm gear mechanism can be meshed with the second tooth portion 210 of the outer ring 200, and the output mechanism includes a first tooth portion 110.

[0031] In addition, the present application also provides a vehicle, which is equipped with the above-mentioned window lifting and lowering drive device.
