[0029] The utility model will be described in detail in combination with the drawings.
[0030] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.
[0031] Embodiment 1
[0032] As shown in the figure, the embodiment provides a footrest for a backpack boat, which comprises a footrest bag body with one end open, a bag body closure, and an exhaust assembly. The bag body closure is arranged on the opening of the footrest bag body, and the bag body closure can seal the opening of the footrest bag body and form a first sealed cavity inside the footrest bag body.
[0033] In this application, the reason for filling water in the footrest bag body is that water is easy to obtain in the wild, and the portability of the backpack boat is also retained. Specifically, when the user reaches the water edge, it is easy to pour water into the footrest, and the overall weight will not be greatly increased.
[0034] In one specific example, the bag body closure comprises a supporting hard edge, a soft tape, and a detachable connecting assembly. Further, the supporting hard edge and the soft tape are respectively a group; the supporting hard edge is correspondingly arranged on both sides of the open end of the footrest bag body and connected with the open end of the footrest bag body as a whole, and the soft tape is correspondingly arranged on the inner side of the supporting hard edge or the inner side of the footrest bag body, and the two soft tapes are arranged opposite to each other. At the same time, the two ends of the detachable connecting assembly are respectively connected with the open end of the footrest bag body. The end of the footrest bag body opposite to the open end is referred to as the closed end of the footrest bag body; when the supporting hard edge is continuously bent in one direction from the open end to the closed end, the supporting hard edge and the soft tape cooperated with the footrest bag body can form a first sealed cavity inside the footrest bag body; the number of continuous bending is at least three turns. Further, the supporting hard edge and the soft tape are respectively in strip shape; preferably, the width of the soft tape is greater than the width of the supporting hard edge. Preferably, the soft tape is made of TPU material, which can ensure flexibility at low temperature.
[0035] When the water in the footrest bag body is insufficient, if there is no detachable connecting assembly, after the footrest bag body is bent, the footrest bag body will slowly loosen, and the sealing performance of the footrest cannot be guaranteed. The detachable connecting assembly is a snap buckle assembly; further, the detachable connecting assembly comprises a male buckle and a female buckle matched with the male buckle, and the two ends of the detachable connecting assembly are respectively connected with the open end of the footrest bag body. When the male buckle is connected with the female buckle, a circular ring structure is formed between the open end of the footrest bag body and the detachable connecting assembly. By using this structure, when the footrest is not used, the male buckle and the female buckle are in a separated state; when the footrest bag body needs to be sealed, the male buckle and the female buckle are inserted, and a circular ring structure is formed between the open end of the footrest bag body and the detachable connecting assembly.
[0036] The exhaust assembly comprises a connecting air pipe, an air pipe valve for controlling the communication or isolation of the connecting air pipe with the outside, one end of the connecting air pipe is communicated with the first sealed cavity, and the air pipe valve is arranged at the other end of the connecting air pipe and the gas in the first sealed cavity can be sequentially exhausted through the connecting air pipe and the air pipe valve.
[0037] In the present application, the main purpose of arranging the exhaust assembly is to exhaust the excess air in the first sealed cavity. When the foot pedal bag body is filled with water, it is often in a state of air-water mixture, similar to a half-filled water state, and when the foot pedal bag body shakes, the water will still shake randomly in the foot pedal bag body; after the air in the foot pedal bag body is exhausted, the whole becomes a solid, and the whole shakes less. In addition, the inventor has found that if the air in the foot pedal bag body is not exhausted, the foot pedal is prone to deflation.
[0038] Further, a handle arranged on the foot pedal bag body and a connecting piece connected with the foot pedal bag body are further included. The handle is beneficial to the lifting and placing operation of the foot pedal bag body, and the connecting piece is used for the relative connection and fixation between the foot pedal bag body and the backpack boat, and the backpack boat should be provided with a buckle matched with the connecting piece.
[0039] The foot pedal with the above structure has the following use process: after a user fills the foot pedal bag body with water of a required weight through the open end of the foot pedal bag body, continuously bends the foot pedal bag body in a single direction along the direction from the open end to the closed end with the support hard edge as the support to a set position; at this time, the open end of the foot pedal bag body and the detachable connecting assembly form a circular ring structure through the connection of the detachable connecting assembly; then the excess air in the foot pedal bag body is exhausted through the exhaust assembly, and then the air pipe valve is closed.
[0040] As for the ordinary backpack boat, when a user unfolds the backpack boat and places it in a water area, the user is in the cabin of the backpack boat. At this time, the backpack boat has only one center of gravity. When the foot pedal of the present application is placed in the head of the cabin of the backpack boat, it is equivalent to adding an extra weight in the backpack boat, and the foot pedal has corresponding inertial potential energy.
[0041] Based on the existing backpack boat structure without a foot pedal, when the user paddles on the right side, the boat body will swing quickly to the side. Based on the improved structure, when the user paddles on the right side in the heading direction of the boat body, the boat body will first remain based on the existence of inertial potential energy, and the boat body will not immediately swing to the left side; when the boat body is in the remaining state, the user starts to paddle on the left side, and based on the existence of inertial potential energy, the left and right side forces cancel each other out; thus, the boat body has good heading stability.
[0042] When the hull is in water, it is affected by waves, the ship body has up and down direction swing, so that the existing no pedal backpack boat structure has large vertical direction swing. Based on the existing no pedal backpack boat structure, when the backpack boat drives forward, the ship bottom has a wave making resistance, the wave making resistance makes the ship head to tilt up a little; when the external force disappears, the ship head tilts down again; the process of the ship head up and down fluctuation consumes part of the energy. Further, based on the improved structure, when the ship body swings along the vertical direction, based on the existence of the pedal of the application, when the backpack boat drives forward, the inertia of the weight of the pedal itself can inhibit the tilt up amplitude of the ship head; on the contrary, when the external force disappears, the amplitude of the ship head swinging down is also reduced; it can be seen that based on the existence of the pedal of the application, the ship body tends to be stable as a whole, so that the energy can be concentrated in the forward direction of the backpack boat. By using this way, the stability of the backpack boat work can be enhanced, and the user's rowing experience is improved.
[0043] Based on the existing no pedal backpack boat structure, the motion of the backpack boat can be simplified into a wave, and the wave shape of the wave is chaotic; and after the pedal of the application is used in the backpack boat, the frequency and amplitude of the corresponding wave of the backpack boat are improved, and the whole operation of the backpack boat is more stable.
[0044] Further, the existing technology adopts a zipper to seal. The zipper has the following limitations: 1) it is generally difficult to achieve absolute sealing effect by using the zipper, only some brands can achieve absolute sealing effect; 2) it is not easy to adjust the capacity of the pedal by using the existing zipper sealing form.
[0045] And by using the scheme of the embodiment, not only the use of high-end zippers can be effectively reduced to reduce the overall cost, but also the capacity of the pedal can be easily adjusted to meet the needs of different pedal weights, and better adaptability is achieved. Further, the test structure shows that the pedal of the embodiment has reliable performance, low manufacturing cost, strong adaptability, high adaptability and wide application range.
[0046] In summary, based on the improved structure, the overall fluctuation of the backpack boat is small, the fluctuation amplitude is inhibited, and the whole will feel better to row; the ship body not only has good heading stability, but also has up and down direction stability. Based on the improved structure, the pedal is placed in the driving direction cabin of the backpack boat, which not only realizes water storage in the limited space, but also realizes the pedal function, provides a support point for the user, and is helpful to reduce the fatigue of the rower after long-term use, and improves the experience of the user.
[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
