It is especially for the seat. From the comfort of the brake seat [previous technology] - the power of the bicycle is mainly the chain, the wheel transmits the power to the wheel, so the ride 're-passing the seat is used for cutting and stability, the bicycle The pedals and the basic comfort are easy to step on as shown in the figure (Α), which is a general view of the general male 夕 构 ' ‘ ‘ ‘ f chair knot...t丞 is not composed of a plastic ",: pad 12 'and 'group seat bow' 1 , plastic f" free 脰 1 1 is the main mechanical structure supporting the entire seat work body The cushion 1 2 is made of soft material such as sponge or foam, and is mainly used for laying on the top of the shell of the plastic casing 1 1 to increase the softness of the seat i 〇 and the contact portion of the rider's buttocks. The plastic housing 1X is provided with front and rear fixed blocks 1 1 and 1 1 2 for fixing the seat bow 13 at the front and rear shell bottoms thereof, so that the seat bow 13 can be coupled to the seat 1 The bottom of the cymbal is used as a member of the seat 1 联 and the bicycle seat tube (not shown). In addition, the plastic housing 1 1 is provided with a recess 1 1 3 at a position where the top of the shell is biased toward the front end of the seat cymbal, so that the top shape M303869 of the plastic shell is recessed to facilitate the cushion of the portion. The thickness of 1 2 is to enhance the protection effect on the perineal portion of the rider; however, the recess 1 1 3 of the conventional plastic housing 1 1 is disposed between the front and rear fixed blocks 1 1 1 and 1 1 2, and is guided. As a result, the entire recessed area cannot extend to the foremost end of the seat 10, and in general, the rider's general riding habits do not completely protect the rider's perineum. This phenomenon is particularly noticeable for male riders. Even if it is possible to cause infertility of the male rider due to long riding time; further, when the seat bow 13 is fixed with the front fixing block 111, they are arranged side by side, as shown in the first figure (B). As shown, the plastic case 1 1 and even the seat cushion fixed to the seat bow 13 are prone to stress concentration, and the user is likely to have an uncomfortable feeling such as a raised foreign object when approaching the front fixed block when riding. This phenomenon is especially noticeable for male riders. [New content] In view of this, the present invention aims to provide a bicycle seat structure which can effectively improve the comfort of the bicycle seat, especially for the rider's perineal part; the overall seat is basically a plastic The housing, a set of cushions, and a set of seat arches are formed, and the plastic housing is provided with a recess extending toward the front at a middle portion of the top of the shell. The main point is that the bottom of the concave shell of the plastic shell extends to the front edge of the plastic casing, and the front fixing block for fixing the seat bow below the plastic casing is disposed at the bottom of the shell of the concave portion of the plastic casing, The recess can be extended to the front end of the plastic housing, which increases the thickness of the seat cushion at the front end of the seat, greatly enhances the comfort of the bicycle seat, and protects the rider's perineal area from the M303869. [Embodiment] The creation of the "seat structure of the bicycle is effective to improve the comfort of the bicycle seat:" θ is provided in a bicycle seat that can form a complete protection function. 纟: Constructed: = Department: = The body seat is basically composed of a plastic shell cushion 1 2 and a set of seat bows i 3 . ,, - Among them, 'Plastic Shell 1! is a mechanical structure that supports the plastic body, and it sits...^ The main system of the ugly ugly yu is used for the soft materials such as sea foam. At the top of the shell of the shell 以, to increase the softness of the contact area of the buttocks (4); the bottom of the shell of the plastic: (4) month: the bottom of the shell is fixed to the front and the rear of the seat bow 13 = 1 1 , 1 1 2, the seat bow 13 can be connected to the seat! The mouth of the PP is used as the member of the seat 1 联 and the bicycle seat tube (not shown). Similarly, the plastic shell i B has a shell top At the middle of the section, there is a recessed portion 3 extending toward the front of the seat 10, so that the top of the plastic casing is shaped like a depression, so as to increase the thickness of the cushion 12 of the portion, so that the reinforcement can be multiplied. The protective effect of the perineal part; the key point is that the bottom of the recess 1 1 3 extends all the way to the front edge of the plastic housing 1 1 , and the front fixed block 1 1 for fixing the seat bow 13 below the plastic housing 1 1 1 is disposed at the bottom of the shell of the recessed portion 1 1 3 of the plastic casing 1 1. The mountain can be extended to the front of the plastic casing 1 1 by the 'draw portion 1 13 ' The thickness of the seat cushion 1 2 at the front end of the chair 10 greatly enhances the comfort of the M303869 liter bicycle seat 10 and the more complete protection of the rider's perineal part f. In the specific implementation, the recess i can be as The third figure extends completely to the front edge of the plastic casing, so that the top of the front edge of the plastic casing 11 is open. L can be extended as shown in the fourth figure to the plastic shell. The front edge of the body 1 1 is such that the top of the shell of the plastic shell 1 1 is sealed (four), and the recessed portion of the top of the shell of the shell u can be obviously extended to the front end of the seat frame, thereby conforming to the bicycle. The safety protection requirements of the actual riding habits. Further, the seat bow 13 can be composed of two pre-bent metal rods. As shown in the fifth figure, there are two seats for the plastic housing 丄η. The rear end of the bow 13 is inserted into the hole, and the rear fixed line 1 1 2 is respectively provided with a hole for the rear end of the seat bow to extend. 2 1 4 'and the plastic shell! The work is combined to make the front end of the seat bow 3 fixed in front. The fixing points in the block 1 1 1 are separated by an appropriate distance, so that the plastic shell and the seat cushion i2 are not easily stressed at this place, thereby increasing the The rider is comfortable to ride. ★ As mentioned above, this creation provides a better and feasible plastic body structure for bicycle seats. 申请Apply a new type of patent application; however, the above implementation: month and schema The preferred embodiment of this creation is not limited to the imperial edict 'is a similarity to the structure, installation, characteristics, etc. of the creation, and the field δ ' should be the creation purpose of the creation and the scope of the patent application. The first figure (1) is a structural cross-sectional view of a conventional bicycle seat. M3 03 869 ί is a three-dimensional structure of a conventional bicycle seat.
