The utility model has the advantages that the structural design of the pivot arm, the base and the shock absorber unit disposed between the swing arm and the base can produce a good buffer and shock absorber effect at the bicycle handle. To improve ride comfort and safety. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. As shown in FIG. 1 to FIG. 3, a first preferred embodiment of the bicycle handle shock absorber 2 of the present invention is disposed between a handle tube 1 and a stalk 3, and the bicycle handle suspension device 2 includes A pivot arm 21, a base 22, and a suspension unit 23. The pivot arm 21 is oscillated up and down by the handle tube i, and has a loop portion 211 for the handle tube 1 to be placed and fixed, and a pivot portion 212 opposite to the loop portion 211. The base 22 is fixed to a top end portion of the vertical rod 3, and has a base body 221 fixed to the top end portion of the vertical rod 3, and a front portion from the bottom of the base body 221 Extending horizontally to the extended seat 222 below the loop portion 2 ι of the swing arm 21; one of the base body 221 has a double lug shape and is capable of transmitting through a pivot to the pivot arm 21 The pivoting portion 212 is pivotally connected, and the extending base 222 has a through hole 223 which is longitudinally and has an upper narrow and a lower width. The suspension unit 23 is disposed between the pivoting arm 21 and the extended seat 222 of the base 22, and has a compressible deformation clamp disposed on a bottom surface of the pivot arm 21 and the extension seat. The elastic member 231 between the top surfaces of the body 222 is vertically slidably and slidably disposed in the through hole 223 of the elastic member 231 and the extending base 222, and a top end portion thereof is screwed into the swing arm a bolt shaft 232 at the collar portion 211 of the 21, a buffer block 233 fixed on the shaft 232 and located in the elastic member 231 and abutting against a bottom surface of the swing arm 21; a cushion 234, 235 fastened to a bottom end of the bolt shaft 232 and abutting against a bottom surface of the extension base 222, and a set fixed on the bolt shaft 232 and stacked on the soft In the present embodiment, the elastic member 231 is a compression spring, and in addition, the portion of the 7 201006720 cushion 234, 235 may be selected from only one of them. The pad 234 is detachably received in the width of the through hole 223. Furthermore, the pin shaft 232 has a head portion 237 that is constant below the bottom surface of the extension body 222, and extends upwardly from the head portion 237 and is slidably inserted through the through hole 223 and the elastic member 231. The smooth section 238 in the middle, and a threaded section 239 extending upward from the smooth section 238 and partially screwed into the collar portion 211. The buffer block 233 is fixed to the threaded section 239, and the two cushions 234, 235 and the washer 236 are vertically and sequentially stacked and fixed at the head 237 of the smooth section 238. As shown in FIG. 4, when the handle tube is subjected to a shock, the pivot arm 21 swings synchronously and downwardly, thereby forcing the elastic member 231 to be in a compressed state, and simultaneously driving the bolt shaft 232 to slide downward. Moving, the two cushions 234 235 and the washers 236 and the like are completely away from the extension body 222. During the process, if the shock absorber of the handle tube 1 is less affected, that is, the pivoting arm 21 swings downward by a small amplitude, as long as the resistance generated by the compression deformation of the elastic member 231 (the deformation amount is small) is generated. The function is sufficient to absorb and alleviate the shock impact force of the handle of the handle to achieve the shock absorber effect; and if the shock of the handle of the handlebar is relatively severe, the swing arm 21 swings downwardly, except In addition to the compression deformation of the elastic member 231 (the deformation amount is large at this time), the pivoting arm 21 further drives the buffer block 233 to touch the top surface of the extension body 222, so that the buffer block can also The shock absorption force of the handle tube 1 is absorbed, so that the elastic member 231 cooperates with the buffer block 233 to produce better cushioning and shock-absorbing effects. Incidentally, the elasticity of the elastic member 201006720 23 1 can be adjusted through the pin shaft 232 , to change the softness and hardness of the cushioning effect of the self-mu suspension device 2. For example, the threaded section 239 of the bolt shaft 232 is at the screwing depth of the collar portion 211 of the pivot arm 21, that is, the pivoting arm 21 and the extension seat body 222 ^ ^ Π歹The distance in the force state causes the elastic member 231 to be in a tight state, so that the bicycle handle suspension device 2 can exhibit a relatively hard buffering suspension effect; on the contrary, the bolt shaft 232 is rotated away. 60 of the pivoting arm η can make the elastic member 231

When the shock shock of the handle f1 is lost, the elastic member 23丄 (or the relief 233) releases the anti-deformation force accumulated during the pressing to drive the pivot arm 21 toward The upper swing is reset, and the bolt shaft 232, the cushions 234, 235 and the washer 236 are also slid upwardly and resetted, and the buffer structure design of the two cushions 234 and 235 can prevent the The head 237 of the bolt shaft 232 directly impacts the extension body 222 when it is moved up and down, ensuring that the pivot arm 21, the bolt shaft 232 and the elastic member 231 are smooth, smooth and noise-free during the resetting process. of. Therefore, the pivoting arm 21, the base 22, and the suspension unit 23 disposed between the pivot arm 21 and the base 22 are designed to provide a good cushioning at the bicycle handle. The shock effect gives the rider's hand a good grip comfort' reduces the grip load and force burden, and ensures a stable grip between the rider's hand and the bicycle handle, thereby improving ride comfort. And security. As shown in FIG. 5 and FIG. 6 , the bicycle handle shock absorber 201006720 1: is a second preferred embodiment, and the main difference from the above-described first preferred embodiment is: the bicycle handle suspension The mounting "" is a shock absorbing unit 23' having two phases juxtaposed and tilted between the front and rear sides to be tested between the 219 and the extension body 222 of the base 22. In the middle of the eight-seat mother, a shock-absorbing soap element 23 is compared to a squatter, and has only one soft 塾234. Of course, the bicycle handle suspension device 2 can also achieve a good cushioning and shock absorbing effect to improve riding comfort and safety.
