Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.
Referring to fig. 2 to 8, the simple cam rotating shaft for a vehicle includes a cam rotating shaft 100, a first step 200 is disposed at one end 100a of the cam rotating shaft 100, a second step 300 is disposed at the other end 100b of the cam rotating shaft 100, an open washer 400 is disposed at the periphery of the second step 300, a fixed tooth 110 engaged with the adjusting transmission assembly 10 is disposed on the cam rotating shaft 100, the outer diameter of the first step 200 is smaller than the outer diameter of the second step 300, the outer diameter of the second step 300 is smaller than the outer diameter of the cam rotating shaft 100, and the outer diameter of the cam rotating shaft 100 is smaller than the outer diameter of the open washer 400. The side of the cam shaft 100 in this embodiment is a flat structure 120.
The split washer 400 is provided in an inverted U-shaped structure, and an open end 400a of the split washer 400 is engaged with the second step 300.
The working principle of the utility model is as follows:
during assembly, the head of the cam rotating shaft 100 is inserted into the adjusting transmission assembly 10, the spring member 20, the adjusting switch assembly 30 and the spring member 40 in sequence. The fitting hole 50a of the headrest frame assembly 50 is fitted with the second step 300 of the cam rotary shaft 100, and the second step 300 is inserted into the fitting hole 50a of the headrest frame assembly 50 in an inclined manner. When the cam shaft 100 is completely positioned in the assembly hole 50a, the first step 200 may be inserted into the assembly hole 60a of the headrest frame assembly 60, the side 130 of the cam shaft 100 is attached to the headrest frame assembly 60, at this time, the second step 300 is spaced apart from the headrest frame assembly 50, and then the open washer 400 is inserted into the second step 300, at this time, the cam shaft 100 may be fixed in the headrest frame assembly 50, in order to prevent the open washer 400 from falling off when the cam shaft 100 rotates, the adjusting transmission assembly 10 is provided with the washer hole 11, the assembly hole 12 of the adjusting transmission assembly 10 is engaged with the fixed gear 110 to be fixed to the cam shaft 100, the fixed gear 110 may eliminate a gap and prevent the fall-off, the open washer 400 is inserted into the washer hole 11 of the adjusting transmission assembly 10, and both ends of the first step 200 and the second step 300 are riveted to the cam shaft 100 in the headrest frame assembly 50, 60, a certain gap is required to be reserved during riveting, the cam rotating shaft 100 can rotate in the headrest frame assembly 50 and 60, a spring clamping groove 13 is arranged in the adjusting transmission assembly 10, one end 21 of the spring element 20 is arranged in the spring clamping groove 13, the other end 22 of the spring element 20 is arranged in a spring clamping groove 51 arranged in the headrest frame assembly 50, an assembling hole 30a of the adjusting switch assembly 30 is assembled with the cam rotating shaft 100, the adjusting switch assembly 30 can not rotate on the cam rotating shaft 100 due to the design of the cam rotating shaft 100, a spring clamping groove 31 is arranged on the adjusting switch assembly 30, one end 41 of the spring element 40 is arranged in the spring clamping groove 31, and the other end 42 of the spring element 40 is arranged in a spring clamping groove 61 arranged in the headrest frame assembly 60.
