AI Technical Summary
The existing passenger car seat adjustment gears are relatively heavy, which increases the vehicle's weight and fuel consumption.
The lightweight passenger car seat adjustment gear, which is integrally formed by powder metallurgy, reduces the weight of the gear by setting an inner groove surface between the shaft and the straight teeth and setting structural reinforcing ribs in the inner groove surface. At the same time, the shaft is set with an inner concave arc surface and the outer end of the straight teeth forms an inner inclined groove surface to reduce the volume and enhance the structural strength.
While reducing the weight of the gears, the structural strength and durability of the passenger car seat adjustment gears were ensured, thus reducing the overall weight of the car.

[0006] Preferably, the inner groove surface is provided with a structure reinforcing rib.
[0007] Preferably, the structure reinforcing rib is provided with several channels, and the structure reinforcing rib is vertically distributed around the shaft body.
[0008] Preferably, the structure reinforcing rib is provided with a first annular reinforcing rib at the connection with the shaft body, and a second annular reinforcing rib at the connection with the straight teeth.
[0009] Compared with the prior art, the utility model has the following advantages: by setting the inner groove surface between the shaft body and the straight teeth, the weight of the gear is reduced, and the structure reinforcing rib is arranged in the inner groove surface to ensure the structural strength of the gear; under the condition of ensuring the overall structural strength of the gear, the inner concave arc surface is arranged on the shaft body, the outer end of the straight teeth is recessed to form the inner inclined groove surface, the volume of the gear is further reduced, so that the weight of the passenger car seat adjustment gear is reduced while ensuring the structural strength. BRIEF DESCRIPTION OF DRAWINGS
[0010] Fig. 1 It is the top view of the utility model.
[0011] Fig. 2 is a side view of the utility model.
[0012] Among them, 10 - straight tooth, 11 - shaft body, 12 - inner groove surface, 13 - structure reinforcing rib, 14 - inner inclined groove surface, 15 - inner concave surface, 16 - first annular reinforcing rib, 17 - second annular reinforcing rib. DETAILED DESCRIPTION
[0013] The utility model is further illustrated below in combination with the drawings and specific embodiments, and it should be understood that these embodiments are only used for illustrating the utility model and not for limiting the scope of the utility model, and after reading the utility model, various equivalent modifications of the utility model made by those skilled in the art all fall within the scope defined by the claims attached to the present application.
[0014] As Figs. 1-2 Lightweight passenger car seat adjusting gear shown in the figure, including gear body, gear body is powder metallurgy integrated molding, the middle of gear body is equipped with shaft body 11, the end face of shaft body 11 is inwards recessed and forms inner concave surface 15, the outer periphery of gear body is provided with straight tooth 10, the outer end of straight tooth 10 is inwards recessed and forms inner inclined groove surface 14, and inner groove surface 12 is formed by hollowing out between shaft body 11 and straight tooth 10.
[0015] Need to be further explained, by setting inner groove surface 12 between shaft body 11 and straight tooth 10, the weight of gear is reduced, and structure reinforcing rib 13 is arranged in inner groove surface 12, to ensure the structural strength of gear;Under the guarantee of the structural strength of the whole gear, inner concave surface 15 is arranged in shaft body 11, the outer end of straight tooth 10 is inwards recessed and forms inner inclined groove surface 14, to further reduce the volume of gear, so that the weight of passenger car seat adjusting gear is reduced while ensuring its structural strength.
[0016] Further, inner groove surface 12 is provided with structure reinforcing rib 13, structure reinforcing rib 13 is provided with eight, and structure reinforcing rib 13 is vertically distributed around the center of shaft body 11, first annular reinforcing rib 16 is arranged at the connecting part of structure reinforcing rib 13 and shaft body 11, and second annular reinforcing rib 17 is arranged at the connecting part of structure reinforcing rib 13 and straight tooth 10.By setting structure reinforcing rib 13, the side stress of straight tooth 10 is conducted to structure reinforcing rib 13, to avoid the side stress damage caused by the pressure of straight tooth 10 to gear body when inner groove surface 12 is set too deep, and the bearing area of side stress is further increased by first structure reinforcing rib 16 and second structure reinforcing rib 17, to reduce stress damage.
