When the clamping force of the user's legs on the saddle increases, the body unit naturally deforms inwardly, and the inner tube unit can contract relative to the outer tube unit, relieving the pressure of the saddle on the human body; as the body unit deforms, the clamping force of the user's legs on the saddle naturally decreases, and the inner tube unit cannot contract relative to the outer tube unit, so that the body unit automatically stops deforming and is in the most comfortable state for the human body. The entire body unit deformation process is adjusted unconsciously during the user's riding, and is always in the most comfortable state, which conforms to ergonomics and greatly improves the user experience.

[0038] 2. Through the structural design of the inner tube unit and the outer tube unit, when the clamping force of the user's legs on the saddle increases, the body unit naturally deforms inwardly, and the clamping force can completely overcome the elastic force of the spring element through force transmission, and the elastic teeth can completely contract, i.e. the inner tube unit can contract relative to the outer tube unit, relieving the pressure of the saddle on the human body; as the body unit deforms, the clamping force of the user's legs on the saddle naturally decreases, and the clamping force cannot completely overcome the elastic force of the spring element through force transmission, and the elastic teeth cannot completely contract, so that the inner tube unit cannot contract relative to the outer tube unit, so that the body unit automatically stops deforming and is in the most comfortable state for the human body.

[0039] 3. The detachable connection between the elastic teeth and the guide plate, and the detachable connection between the action coupling block and the guide plate, ensure that they can be positioned and matched during assembly, without considering the disconnection of the guide plate from the elastic teeth and the action coupling block. The guide plate, the elastic teeth and the action coupling block can be configured in a quick connection and disconnection manner, thereby improving the stability and quickness of the connection between the guide plate and the elastic teeth and the action coupling block during the assembly process of the inner tube unit.

[0040] 4.

DETAILED DESCRIPTION

[0061] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is described and explained below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application. Based on the examples provided by the present application, all other examples obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0062] As Figures 1-16As shown, the present embodiment provides an ergonomic deformable saddle, which comprises a base mounting part 100 and a seat body 300 mounted on the base mounting part 100 through a framework unit 200, wherein the lower end surface of the base mounting part 100 is fixedly provided with a support tube 110, and the support tube 110 is inserted on the frame of a bicycle, the framework unit 200 comprises a pair of left and right mirror image configured framework bodies 210, and the middle part of the framework body 210 is mounted on the base mounting part 100, and the front and rear ends of the framework body 210 are mounted on the seat body 300, thereby forming a saddle.

[0063] In other words, the framework unit 200 is combined with the seat body 300 as a whole seat, and the whole seat is combined with the base mounting part 100 through the middle part of the framework body 210, and the whole saddle is combined with the frame of the bicycle through the support tube 110 at the lower end surface of the base mounting part 100.

[0064] Specifically, the seat body 300 comprises a body unit 310 to support the body weight of a user, and the front end of the bottom of the body unit 310 is fixedly provided with a front mounting block 320, and the rear end of the bottom of the body unit 310 is fixedly provided with a pair of rear mounting blocks 330, and the front ends of the pair of framework bodies 210 are mounted in the front mounting block 320, and the rear ends of the pair of framework bodies 210 are respectively mounted in the pair of rear mounting blocks 330.

[0065] It should be noted that, in order to facilitate the assembly of the framework body 210 with the base mounting part 100 and the seat body 300, the framework body 210 comprises a middle horizontal section 211, a front end bending part 212 located at one end of the middle horizontal section 211, and a rear end bending part 213 located at the other end of the middle horizontal section 211, and the front end bending part 212 is bent inward and upward, and the rear end bending part 213 is bent outward and upward, so as to adapt to the overall structure of the seat body 300.

[0066] It can be understood that, in the conventional bicycle saddle, the framework unit 200 is rigidly configured, and the overall structure of the body unit 310 of the seat body 300 cannot be deformed. However, during the riding process of a user, at a certain moment, especially when the body is straight or slightly inclined backward, the clamping force of the legs on the saddle increases, which causes the saddle 200 to press the local body more intensively, resulting in discomfort.

[0067] In order to eliminate the above-mentioned defects, the deformable saddle of the present embodiment is configured that the body unit 310 is provided with a wide slot 311 in the middle part, and the front end of the wide slot 311 is formed as a narrow waist part 312 of the body unit 310, so that the body unit 310 will be deformed and bent inward when the legs clamp the saddle; correspondingly, the framework body 210 is rotatably mounted in the base mounting part 100.

[0068] In other words, the front and rear ends of the wide slot 311 are respectively provided with a front connecting sheet 313 and a rear connecting sheet 314, and the front connecting sheet 313 and the rear connecting sheet 314 are both structure weakening components, so that the body unit 310 can be deformed to bend inward. The base mounting part 100 is provided with a hinge mounting hole 101 penetrating front and back, and the middle horizontal section 211 of the framework body 210 is rotatably mounted in the hinge mounting hole 101.

[0069] Wherein, the upper side of the base mounting part 100 is further fixedly provided with a fixed shaft 120, and a pair of rear mounting blocks 330 are respectively fixedly provided with an inner tube body unit 400 on the opposite sides, and the outer tube body unit 500 is hingedly mounted on the fixed shaft 120, and the inner tube body unit 400 can be telescoped relative to the outer tube body unit 500. In one case, the inner tube body unit 400 can be telescoped relative to the outer tube body unit 500, and in another case, the inner tube body unit 400 cannot be telescoped relative to the outer tube body unit 500.

[0070] Therefore, when the clamping force of the user's legs on the saddle becomes larger, the body unit 310 is deformed to bend inward, and a pair of framework bodies 210 swing inward with the middle horizontal section 211 as the rotation fulcrum, and generate a force to make the inner tube body unit 400 contract relative to the outer tube body unit 500. In one case, the inner tube body unit 400 can contract relative to the outer tube body unit 500, and the body unit 310 deforms inward to relieve the pressure of the saddle on the human body; in another case, as the body unit 310 deforms, the clamping force of the legs on the saddle becomes smaller, and at this time, the inner tube body unit 400 cannot be telescoped relative to the outer tube body unit 500, so that the body unit 310 is in the most comfortable state for the human body.

[0071] Through the above arrangement, when the clamping force of the user's legs on the saddle becomes larger, the body unit 310 naturally deforms to bend inward, the inner tube body unit 400 can contract relative to the outer tube body unit 500, and the pressure of the saddle on the human body is relieved; as the body unit 310 deforms, the clamping force of the legs on the saddle naturally becomes smaller, and the inner tube body unit 400 cannot be telescoped relative to the outer tube body unit 500, so that the body unit 310 automatically stops deforming and is in the most comfortable state for the human body. The deformation process of the whole body unit 310 is unconsciously adjusted during the user's riding, and is always in the most comfortable state, which conforms to the ergonomics and greatly improves the user experience.

[0072] In other words, the inner tube unit 400 is provided with a first flange 410 on the side away from the outer tube unit 500, so as to be fixedly installed on the rear mounting block 330; the outer tube unit 500 is fixedly installed with a second flange 510 on the side away from the inner tube unit 400, and the second flange 510 is provided with a hinge ring 511 matched with the fixed shaft 120 on the side away from the inner tube unit 400, so as to be rotatably installed on the fixed shaft 120.

[0073] Specifically, the end surface of the inner tube unit 400 facing the outer tube unit 500 is outwardly extended to form a rectangular insertion part 420, the end surface of the outer tube unit 500 facing the inner tube unit 400 is provided with a rectangular insertion hole 520, and the rectangular insertion hole 520 is matched with the rectangular insertion part 420, so as to realize the relative expansion and contraction between the inner tube unit 400 and the outer tube unit 500. Wherein, one side wall of the rectangular insertion hole 520 is provided with a plurality of continuously arranged tooth grooves 521, and one side surface of the rectangular insertion part 420 is provided with elastic teeth 430 matched with the tooth grooves 521, and the number of the teeth of the elastic teeth 430 is less than the number of the tooth grooves 521.

[0074] Therefore, when the clamping force of the user's legs on the saddle becomes larger, a force is generated for the inner tube unit 400 to contract relative to the outer tube unit 500. In one case, the elastic teeth 430 can be completely contracted, continuously from one tooth groove 521 to the next tooth groove 521, so that the inner tube unit 400 can contract relative to the outer tube unit 500; in another case, the clamping force of the legs on the saddle becomes smaller, the elastic teeth 430 cannot be completely contracted, and the elastic teeth 430 remain in one tooth groove 521, so that the inner tube unit 400 cannot expand and contract relative to the outer tube unit 500.

[0075] Through the above arrangement, when the clamping force of the user's legs on the saddle becomes larger, the body unit 310 is naturally deformed inwardly, the elastic teeth 430 can be completely contracted, continuously from one tooth groove 521 to the next tooth groove 521, so as to relieve the pressure of the saddle on the local human body; with the deformation of the body unit 310, the clamping force of the legs on the saddle naturally becomes smaller, the elastic teeth 430 cannot be completely contracted, and the elastic teeth 430 remain in one tooth groove 521, so that the body unit 310 automatically stops deforming and is in the most comfortable state for the human body.

[0076] In this embodiment, the one side surface of the rectangular plug-in part 420 is provided with a rectangular stepped hole 421, the elastic tooth 430 comprises a tooth plate 431 and a plurality of teeth 432 fixedly arranged on the upper end surface of the tooth plate 431, and the tooth plate 431 is located in the small-diameter part of the rectangular stepped hole 421. A slidable guide plate 440 is arranged in the large-diameter part of the rectangular stepped hole 421, and the lower end of the tooth plate 431 is detachably connected with the upper end of the guide plate 440. Thus, the guide plate 440 slides up and down in the large-diameter part of the rectangular stepped hole 421, so that the elastic tooth 430 can be extended out of the rectangular stepped hole 421 or retracted into the rectangular stepped hole 421.

[0077] In order to realize elastic extension and retraction, a configuration cavity 422 is further arranged in the rectangular plug-in part 420, and an elastic extension and retraction plate 450 is slidably arranged in the configuration cavity 422. A spring element 460 is further arranged in the configuration cavity 422 and located below the elastic extension and retraction plate 450, so as to apply an elastic force to the elastic extension and retraction plate 450. An action coupling block 470 is further arranged in the configuration cavity 422 and located above the elastic extension and retraction plate 450, so as to realize the action coupling of the elastic tooth 430 and the elastic extension and retraction plate 450. Thus, the elastic tooth 430, which is coupled with the elastic extension and retraction plate 450, can realize elastic extension and retraction through the action of the spring element 460 on the elastic extension and retraction plate 450.

[0078] The action coupling block 470 comprises a body part 471 and a guide connecting part 472 arranged on one side of the body part 471, and the guide connecting part 472 penetrates the rectangular plug-in part 420 into the rectangular stepped hole 421 and is detachably connected with the lower end of the guide plate 440. The lower side of the body part 471 is provided with an inclined surface 473, and the inclined surface 473 is in contact with the elastic extension and retraction plate 450.

[0079] Therefore, when the clamping force of the two legs of the user on the saddle becomes larger, a force is generated to make the inner tube unit 400 shrink relative to the outer tube unit 500. In one case, the clamping force can completely overcome the elastic force of the spring element 460 through force transmission, so that the elastic tooth 430 can completely shrink and continuously move from one tooth groove 521 to the next tooth groove 521, so that the inner tube unit 400 can shrink relative to the outer tube unit 500. In another case, as the clamping force of the two legs on the saddle becomes smaller, the clamping force cannot completely overcome the elastic force of the spring element 460 through force transmission, the elastic tooth 430 cannot completely shrink, the elastic tooth 430 remains in one tooth groove 521, and the inner tube unit 400 cannot extend and retract relative to the outer tube unit 500.

[0080] With the above arrangement, when the clamping force of the user's legs on the saddle becomes larger, the body unit 310 naturally deforms inwardly under the force, and the clamping force can completely overcome the elastic force of the spring element 460 through force transmission, so that the inner tube unit 400 can be retracted relative to the outer tube unit 500, thereby relieving the pressure of the saddle on the human body; as the body unit 310 deforms, the clamping force of the user's legs on the saddle naturally becomes smaller, and the clamping force cannot completely overcome the elastic force of the spring element 460 through force transmission, so that the inner tube unit 400 cannot be retracted relative to the outer tube unit 500, so that the body unit 310 automatically stops deforming and is in the most comfortable state for the human body.

[0081] It should be noted that after the inner tube unit 400 is assembled, the action connecting block 470 is pressed against the guide plate 440 to move upward in the rectangular stepped hole 421 under the action of the spring element 460, and is limited by the top surface of the large-diameter portion, that is, the spring element 460 always presses the action connecting block 470 and the guide plate 440 together. After the inner tube unit 400 is assembled into the outer tube unit 500, the elastic teeth 430 are always kept from being separated from the guide plate 440 or pressed together with the guide plate 440 under the limiting and / or pressing action of the tooth groove 521.

[0082] In other words, the detachable connection between the elastic teeth 430 and the guide plate 440, and the detachable connection between the action connecting block 470 and the guide plate 440, ensure that they can be easily positioned and matched during assembly, without considering the separation of the guide plate 440 from the elastic teeth 430 and the action connecting block 470. Specifically, the tooth plate 431 and the lower end surface of the guide plate 440 are provided with positioning blocks, and the upper end surface of the guide plate 440 and the guide connecting portion 472 is provided with positioning grooves matched with the positioning blocks. Preferably, the lower end surface of the positioning block and the bottom surface of the positioning groove can be configured with magic tape or magnets and other quick connection and disconnection modes, thereby improving the stability of the connection between the guide plate 440 and the elastic teeth 430 and the action connecting block 470 during the assembly of the inner tube unit 400.

[0083] It should be noted that the spring element 460 of the present embodiment is configured as a positive spring, so that the user can adjust the elastic coefficient of the spring element 460 according to the user's own experience, so that the critical point at which the body unit 310 automatically stops deforming matches the needs of different users when the clamping force of the user's legs on the saddle becomes larger, thereby improving the applicability of the product.

[0084] Specifically, the upper end surface of the elastic expansion plate 450 is provided with a roller 451, and the inclined surface 473 is provided with a roller groove 474, so as to facilitate the relative movement between the elastic expansion plate 450 and the action connecting block 470.

[0085] The spring element 460 comprises a mechanical spring 461 and an adjustable spring 462 in series, and the adjustable spring 462 is fixedly installed at the bottom of the configuration cavity 422, one end of the mechanical spring 461 is connected to the adjustable spring 462, and the other end is connected to the lower end surface of the elastic expansion plate 450, so that the elastic state of the spring element 460 as a whole is changed by adjusting the elastic coefficient of the adjustable spring 462.

[0086] It can be understood that the adjustable spring 462 is electrically adjustable, and the inner tube unit 400 is internally configured with a battery module (not shown). Preferably, in order to further improve the expansion stability of the elastic expansion plate 450, the adjustable spring 462 is centrally provided with a first guide hole 463, the lower end surface of the elastic expansion plate 450 is provided with a first guide column 452, and the first guide column 452 is partially located in the first guide hole 463, and the mechanical spring 461 is sleeved outside the first guide column 452.

[0087] In the embodiment, the reset spring 480 is further arranged in the rectangular insertion hole 520, one end of the reset spring 480 is connected to the top surface of the rectangular insertion hole 520, and the other end is connected to the upper end surface of the rectangular insertion part 420. Thus, when the body unit 310 is deformed during a ride and the ride is ended, the spring element 460 can be adjusted to the minimum elastic coefficient, the elastic teeth 430 are easily fully retracted, and under the action of the reset spring 480, the inner tube unit 400 returns to the maximum extension state, and then the spring element 460 is adjusted to the elastic coefficient corresponding to the working state.

[0088] In other words, the body unit 310 is initially in the maximum open state, and when the rider does not apply an additional clamping force to the body unit 310, the elastic teeth 430 do not retract, and the body unit 310 remains in the initial state; when the additional clamping force is applied, the clamping force overcomes the elastic force of the spring element 460 in one case, and the elastic teeth 430 retract and the inner tube unit 400 shrinks. Preferably, the top surface of the rectangular insertion hole 520 is provided with a second guide column 522, the upper end surface of the rectangular insertion part 420 is provided with a second guide hole 423, and the second guide column 522 is partially located in the second guide hole 423, and the reset spring 480 is sleeved on the second guide column 522.

[0089] It is worth mentioning that the inner tube unit 400, the rectangular plug-in part 420 and the guide plate 440 of the embodiment are configured as an integral module. When the inner tube unit 400 is assembled, the action connecting block 470 is first loaded from below the configuration cavity 422. After the positioning groove of the guide connecting part 472 is aligned with the positioning block of the guide plate 440, the 472 penetrates into the rectangular stepped hole 421 and is combined with the guide plate 440. Secondly, the elastic expansion plate 450 and the spring element 460 are assembled outside and then loaded into the configuration cavity 422 from below. Then, the end cover (not shown) sealing the configuration cavity 422 is assembled, and the roller 451 begins to elastically extrude the roller groove 474. Finally, the elastic tooth 430 is loaded into the rectangular stepped hole 421 and combined with the guide plate 440 through the positioning block, that is, the inner tube unit 400 is formed as a whole.

[0090] Therefore, the deformable saddle of the embodiment can realize modular production, simple and convenient disassembly and assembly, and convenient replacement and maintenance of relatively vulnerable parts such as the elastic tooth 430 and the spring element 460.

[0091] In the embodiment, when the skeleton body 210 swings around the middle horizontal section 211 as the hinge point, in order to facilitate the deformation of the body unit 310, the front end bending part 212 is connected with the front mounting block 320 through the front universal ball (not shown) arranged at the end of the front end bending part 212, and the rear end bending part 213 is connected with the rear mounting block 330 through the rear universal ball 214 arranged at the end of the rear end bending part 213.

[0092] In the embodiment, the base mounting part 100 includes the upper box body 130 and the lower box body 140 which are symmetrically arranged and fixedly connected to form a box body as a whole. The lower end surface of the upper box body 130 is provided with a first semicircular groove 131, and the upper end surface of the lower box body 140 is provided with a second semicircular groove 141. The first semicircular groove 131 and the second semicircular groove 141 are connected to form the hinge mounting hole 101.

[0093] Preferably, the two ends of the first semicircular groove 131 are provided with first semicircular grooves 132, and the size of the first semicircular grooves 132 is greater than that of the first semicircular groove 131. The two ends of the second semicircular groove 141 are provided with second semicircular grooves 142, and the size of the second semicircular grooves 142 is greater than that of the second semicircular groove 141. The first semicircular grooves 132 and the second semicircular grooves 142 are connected to form a limiting ring groove. The two ends of the middle horizontal section 211 are provided with limiting rings 215, and the size of the limiting rings 215 matches the size of the semicircular grooves 132 and 142. Thus, the axial displacement of the skeleton body 210 relative to the base mounting part 100 is limited.

[0094] It should be noted that the upper box body 130 and the lower box body 140 are configured to be detachably connected, for example, the lower end of the upper box body 130 is provided with an upper flange 133, and the upper end surface of the lower box body 140 is provided with a lower flange 143, and the upper box body 130 and the lower box body 140 are detachably connected through the upper flange 133 and the lower flange 143.

[0095] In other words, the support pipe 110 is fixedly installed on the lower end surface of the lower box body 140, and the fixed shaft 120 is fixedly arranged above the upper box body 130.

[0096] Specifically, the upper end surface of the upper box body 130 is provided with a first shaft seat 150, and the rear end surface of the first shaft seat 150 is provided with a circular blind hole 151, and the front end of the fixed shaft 120 is inserted into the circular blind hole 151. Preferably, the circumferential surface of the fixed shaft 120 is provided with a positioning strip groove 121, and the inner side wall of the circular blind hole 151 is provided with a positioning convex strip 152 matched with the positioning strip groove 121. Thus, the rotational freedom of the fixed shaft 120 is limited.

[0097] In order to further improve the stability of the installation of the fixed shaft 120, the base mounting part 100 further comprises a side support 160 mounted on the rear end surface of the box body. Specifically, the side support 160 comprises a reinforcing beam 161, and the front end of the reinforcing beam 161 is fixedly provided with a mounting piece 162, and the rear end of the reinforcing beam 161 is provided with a second shaft seat 170. The upper end surface of the second shaft seat 170 is fixedly provided with a matching assembly ring 171 matched with the fixed shaft 120, and the side surface of the assembly ring 171 is provided with a threaded hole (not shown), and the threaded hole is provided with a locking bolt 172. Thus, the fixed shaft 120 is pressed by tightening the locking bolt 172, or the locking bolt 172 is tightened into the locking hole (not shown) formed in the side surface of the fixed shaft 120, thereby limiting the axial displacement freedom of the fixed shaft 120, and further limiting the rotational freedom of the fixed shaft 120.

[0098] It should be noted that the mounting piece 162 of the base mounting part 100 of the embodiment not only enables the side support 160 to be fixedly installed on the box body, but also improves the stability of the connection of the upper box body 130 and the lower box body 140. Specifically, the upper end of the mounting piece 162 is provided with a first threaded hole 163, and the lower end is provided with a second threaded hole 164; the front end of the upper box body 130 is provided with a first threaded blind hole 134 matched with the first threaded hole 163, and the front end of the lower box body 140 is provided with a second threaded blind hole 144 matched with the second threaded hole 164.

[0099] It is worth mentioning that the deformable saddle of the embodiment integrates the function of self-adapting adjustment of the saddle shape according to the posture of the user's body into the body unit 310, the fixed shaft 120, the inner tube unit 400 and the outer tube unit 500, and the above-mentioned components are modularly configured, facilitating assembly and disassembly, and facilitating maintenance and replacement of internal accessories.
