Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a high - comfort sports shoe. Background Art

[0002] Sports shoes are shoes designed specifically for sports. They not only have the wearing function of ordinary shoes but also possess a series of characteristics optimized for sports needs. The main purpose of sports shoes is to protect the feet of athletes, provide sufficient support and stability, and at the same time reduce the harm caused by the impact force and friction generated during sports to the feet.

[0003] Sports shoes usually include shoe uppers and soles. In order to improve the buffering effect of sports shoes, air bags are often arranged inside the soles. When the foot touches the ground, the air bags will be subjected to pressure and deform, absorbing the impact force when the foot touches the ground. When the pressure disappears, the air bags will return to their original shape and produce a rebound effect. This rebound effect can provide additional support and shock absorption, making the wearer feel more comfortable and stable.

[0004] However, during actual wearing, since the structure of the air bag cannot be changed, the feedback generated when people of different weights and body types step on the air bag is different. In addition, different people have different preferences for the feel of the feet (harder or softer), and the wearing experience of the same pair of sports shoes cannot meet the needs of most people. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a high - comfort sports shoe that can improve the wearing experience by adjusting the air volume of the air bag.

[0006] To achieve the above object, the present utility model provides the following technical solutions: It includes a sole and an upper. An airbag is fixedly arranged above the sole. The airbag includes a front airbag corresponding to the forefoot and a rear airbag corresponding to the heel. The upper end surfaces of the front airbag and the rear airbag serve as pressure-receiving surfaces and are convex. A coordination pipe is connected between the front airbag and the rear airbag. A charging and discharging mechanism for charging and discharging the rear airbag is arranged behind the sole. The charging and discharging mechanism includes a valve body fixed to the sole. One end of the valve body is fixed to the rear airbag, and the other end passes through the sole from the rear. A charging and discharging channel for connecting the rear airbag with the outside is arranged in the valve body. A guiding seat is transversely arranged in the charging and discharging channel. A guiding hole is axially penetrated through the middle of the guiding seat. A plurality of fan-shaped air passing holes are penetrated around the guiding hole of the guiding seat. A guiding rod is slidably arranged in the guiding hole. A sealing member is fixedly arranged at the end of the guiding rod facing away from the rear airbag. The charging and discharging channel includes a frustum section that is hermetically matched with the sealing member. The inner diameter of the frustum section gradually decreases as it is away from the rear airbag. A compression spring is sleeved on the guiding rod and is compressed between the sealing member and the guiding seat. The sealing member is in the shape of a frustum with the small end facing the frustum section. The compression spring presses the sealing member against the side wall of the frustum section to form a cut-off of the charging and discharging channel. The end face of the sealing member facing away from the rear airbag serves as an opening surface. When the opening surface is extruded by high-pressure gas from an external gas source or an external rod-shaped object, the sealing member is separated from the frustum section, forming a connection of the charging and discharging channel.

[0007] By adopting the above technical solution, when the foot feeling is too soft and inflation is required, high-pressure gas enters the air charging and discharging channel from the outside. The high air pressure squeezes the opening surface, causing the seal to retreat, compressing the compression spring. The high-pressure gas sequentially passes through the gap between the seal and the frustum section, the air passing hole, and reaches the rear airbag, simultaneously inflating the front airbag and the rear airbag; when the foot feeling is too hard and deflation is required, a rod-shaped object extends into the air charging and discharging channel from the outside to squeeze the seal to retreat, compressing the compression spring. The high-pressure gas sequentially passes through the air passing hole and the gap between the seal and the frustum section and reaches the outside; when the high-pressure gas charging stops or the rod-shaped object is removed, the compression spring returns to its original state, and the seal and the frustum section resume the sealed fit. The above structure has the following advantages: ① The sports shoes default to the hardest foot feeling. The wearer can insert the rod-shaped object into the air charging and discharging channel according to the foot feeling requirement, adjust the air volume of the airbag in small amounts and multiple times until it is precisely adjusted to the most suitable foot feeling for oneself, thus meeting the wearing experience of most people, and the operation is simple; ② As the wearing time increases, if it is found that there is air leakage, the wearer can fill the air charging and discharging channel with high-pressure gas in small amounts and multiple times by himself or go to the merchant to restore the satisfactory foot feeling and extend the service life; ③ The air charging and discharging are both located in the same channel and in a concealed place at the rear of the shoe, without affecting the overall aesthetics; ④ By coordinating the pipeline to connect the front airbag and the rear airbag into a whole, the total air storage capacity of the airbag is increased. When the wearer performs movements with the front sole landing or the rear heel landing, a better buffering effect can be obtained, giving the wearer a better wearing experience.

[0008] The present utility model is further arranged as follows: A cylindrical section is provided between the end of the air charging and discharging channel communicating with the outside and the frustum section. A limiting ring is provided at the junction of the cylindrical section and the frustum section, and a guiding chamfer is provided on the inner circumference of the limiting ring.

[0009] By adopting the above technical solution, the cylindrical section is used to dock with the inflation nozzle of the high-pressure gas source, and the depth of insertion of the inflation nozzle is limited by the limiting ring to prevent the front end of the inflation nozzle from being closed by the opening surface. When the rod-shaped object is inserted into the cylindrical section, the guiding chamfer on the inner circumference of the limiting ring will guide the rod-shaped object to insert into the inner circle of the limiting ring to achieve stable abutment with the opening surface.

[0010] The present utility model is further arranged as follows: The cylindrical section is provided with a rubber plug that closes the cylindrical section and can be inserted and removed.

[0011] By adopting the above technical solution, the rubber plug is added to prevent foreign objects from entering the cylindrical section and ensure that the rear airbag can be normally charged and discharged.

[0012] The present utility model is further arranged as follows: The material of the seal is metal, and a plurality of axially arranged sealing rings are provided around the frustum side surface of the seal.

[0013] By adopting the above technical solution, metal is selected as the material of the seal, which increases the hardness of the seal. On the one hand, the wear of the opening surface is reduced and the service life is extended. On the other hand, the cooperation with the compression spring is more stable, thus ensuring the sealing stability. At the same time, a plurality of sealing rings are arranged on the outer periphery of the seal, and a reliable multi-sealing structure is formed under the extrusion of the seal and the frustum section.

[0014] The present utility model is further configured as follows: the sole is provided with a mounting hole that is in interference fit with the outer periphery of the valve body. The end of the mounting hole corresponding to the outer side of the sole is provided with a sunk groove. The valve body is located in the sunk groove and is provided with an assembly nut that is in threaded fit with the outer periphery. A sealing ring sleeved on the outer periphery of the valve body is compressively arranged between the assembly nut and the sunk groove. The rubber plug is provided with a cover body that covers the sunk groove.

[0015] By adopting the above technical solution, the valve body is conveniently installed by the cooperation of the valve body and the assembly nut limited in the sunk groove. At the same time, the assembly nut in the sunk groove is hidden by the cover body of the rubber plug, making the appearance more beautiful. Different patterns of rubber plugs can also be replaced to highlight the personality of the wearer. In addition, the outer periphery of the valve body is in interference fit with the mounting hole, and together with the sealing ring, it ensures the reliable assembly of the valve body and prevents external impurities from entering the sole interior.

[0022] Such as Figure 1 — Figure 4As shown in the figure, the utility model discloses a sports shoe with high comfort, which includes a sole 1 and a shoe upper 2. An airbag is fixedly arranged above the sole 1. The airbag includes a front airbag 3 corresponding to the front sole and a rear airbag 4 corresponding to the heel. The upper end surfaces of the front airbag 3 and the rear airbag 4 serve as pressure-receiving surfaces 31 and are convex. A coordination pipeline 5 is connected between the front airbag 3 and the rear airbag 4. A charging and discharging mechanism for charging and discharging the rear airbag 4 is arranged behind the sole 1. The charging and discharging mechanism includes a valve body 6 fixed to the sole 1. One end of the valve body 6 is fixed to the rear airbag 4, and the other end passes through the sole 1 from the rear. A charging and discharging channel 61 for connecting the rear airbag 4 with the outside is arranged in the valve body 6. A guiding seat 62 is transversely arranged in the charging and discharging channel 61. A guiding hole 621 is axially penetrated through the middle of the guiding seat 62. A plurality of fan-shaped air passing holes 622 are penetrated around the guiding hole 621 in the guiding seat 62. A guide rod 63 is slidably arranged in the guiding hole 621. A sealing member 64 is fixedly arranged at the end of the guide rod 63 facing away from the rear airbag 4. The charging and discharging channel 61 includes a frustum section 611 that is sealingly matched with the sealing member 64. The inner diameter of the frustum section 611 gradually decreases as it moves away from the rear airbag 4. A compression spring 65 is sleeved on the guide rod 63 and is compressed between the sealing member 64 and the guiding seat 62. The sealing member 64 is in the shape of a frustum with the small end facing the frustum section 611. The compression spring 65 abuts the side wall of the frustum section 611 with the sealing member 64 to form the cut-off of the charging and discharging channel 61. The end surface of the sealing member 64 facing away from the rear airbag 4 serves as an opening surface 641. When the opening surface 641 is extruded by the high-pressure gas from the external gas source or an external rod-shaped object, the sealing member 64 is separated from the frustum section 611, forming the connection of the charging and discharging channel 61. When the foot feeling is too soft and inflation is required, the high-pressure gas enters the charging and discharging channel 61 from the outside. The high air pressure extrudes the opening surface 641, causing the sealing member 64 to retreat, and the compression spring 65 is compressed. The high-pressure gas sequentially passes through the gap between the sealing member 64 and the frustum section 611 and the air passing holes 622 to reach the rear airbag 4, simultaneously inflating the front airbag 3 and the rear airbag 4. When the foot feeling is too hard and deflation is required, the rod-shaped object extends into the charging and discharging channel 61 from the outside to extrude the sealing member 64 to retreat, and the compression spring 65 is compressed. The high-pressure gas sequentially passes through the air passing holes 622 and the gap between the sealing member 64 and the frustum section 611 to reach the outside. When the high-pressure gas charging stops or the rod-shaped object is removed, the compression spring 65 returns to its original state, and the sealing member 64 and the frustum section 611 resume the sealing fit.The above structure has the following advantages: ① The sports shoes default to the hardest foot feeling (filled with the most gas). The wearer can insert the rod-shaped object into the air charging and discharging channel 61 according to the foot feeling requirement, and adjust the air volume in the airbag in small amounts and multiple times until it is precisely adjusted to the most suitable foot feeling for oneself, so as to meet the wearing experience of most people, and the operation is simple; ② As the wearing time increases, if it is found that there is air leakage, the wearer can fill the air charging and discharging channel 61 with high-pressure gas by himself or go to the merchant in small amounts and multiple times to restore the satisfactory foot feeling and extend the service life; ③ The air charging and discharging are both located in the same channel and in a concealed place at the back of the shoe, which does not affect the overall beauty; ④ By coordinating the pipeline 5 to connect the front airbag 3 and the rear airbag 4 into a whole, the total air storage capacity of the airbag is increased. When the wearer performs sports with the front sole landing or the rear heel landing, a better buffering effect can be obtained, giving the wearer a better wearing experience.

[0023] A cylindrical section 612 is provided between the end of the air charging and discharging channel 61 communicating with the outside and the frustum section 611. A limiting ring 613 is provided at the connection of the cylindrical section 612 and the frustum section 611. A guiding chamfer 6131 is provided on the inner circumference of the limiting ring 613. The cylindrical section 612 is used to dock with the inflation nozzle of the high-pressure air source, and the insertion depth of the inflation nozzle is limited by the limiting ring 613 to prevent the front end of the inflation nozzle from being blocked by the opening surface 641. When the rod-shaped object is inserted into the cylindrical section 612, the guiding chamfer 6131 on the inner circumference of the limiting ring 613 will guide the rod 63-shaped object to insert into the inner circle of the limiting ring 613 to achieve stable abutment with the opening surface 641.

[0024] The cylindrical section 612 is provided with a rubber plug 66 that closes the cylindrical section 612 and can be inserted and removed. Adding the rubber plug 66 can prevent foreign objects from entering the cylindrical section 612 and ensure that the rear airbag 4 can be normally charged and discharged.

[0025] The material of the seal 64 is metal. A plurality of axially arranged sealing rings 642 are provided around the frustum side surface of the seal 64. Selecting metal as the material of the seal 64 increases the hardness of the seal 64. On the one hand, it reduces the wear of the opening surface 641 and extends the service life. On the other hand, it cooperates more stably with the compression spring 65, thereby ensuring the sealing stability. At the same time, a plurality of sealing rings 642 are arranged on the outer circumference of the seal 64 to form a reliable multi-sealing structure under the extrusion of the seal 64 and the frustum section 611.

[0026] The sole 1 is provided with a mounting hole 11 that is in interference fit with the outer periphery of the valve body 6. The end of the mounting hole 11 corresponding to the outer side surface of the sole 1 is provided with a counterbore 111. The valve body 6 is located in the counterbore 111 and is provided with an assembly nut 67 that is in threaded fit with the outer periphery. A sealing ring 68 sleeved on the outer periphery of the valve body 6 is compressively arranged between the assembly nut 67 and the counterbore 111. The rubber plug 66 is provided with a cover body 661 that covers the counterbore 111. The assembly nut 67 that is positioned in the counterbore 111 by the cooperation of the valve body realizes the convenient installation of the valve body. At the same time, the assembly nut 67 in the counterbore 111 is partially hidden by the cover body 661 of the rubber plug 66, making the appearance more beautiful. Different patterns of rubber plugs 66 can also be replaced to highlight the personality of the wearer. In addition, the outer periphery of the valve body 6 is in interference fit with the mounting hole 11, and together with the sealing ring 68, it ensures the reliable assembly of the valve body and prevents external impurities from entering the inside of the sole 1.
