[0031] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only to explain the present disclosure, and cannot be understood as a limitation of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0032] As shown in Figure 1 , Figure 2 and Figure 3 , the present disclosure provides a bow without arrow, comprising a first holding unit 1, a second holding unit 2 and at least one connecting unit 3, the first holding unit 1 comprising a gyroscope 11, the second holding unit 2 being arranged opposite to the first holding unit 1, the connecting unit 3 comprising a rigid arm 31, a rigid string 32 and a hydraulic gas spring 33, the first end of the rigid arm 31 being hinged to the first holding unit 1, the first end of the rigid string 32 being hinged to the second holding unit 2, the second end of the rigid string 32 being hinged to the second end of the rigid arm 31, the hydraulic gas spring 33 being arranged on the first holding unit 1, and the telescopic end of the hydraulic gas spring 33 being hinged to the rigid arm 31.

[0033] It can be understood that, since the first end of the rigid arm 31 is hinged to the first holding unit 1, the first end of the rigid string 32 is hinged to the second holding unit 2, and the second end of the rigid string 32 is hinged to the second end of the rigid arm 31, the second holding unit 2 can move in the direction close to the first holding unit 1 or in the direction away from the first holding unit 1 by the rotation of the rigid arm 31 and the rigid string 32, and since the hydraulic gas spring 33 is arranged on the first holding unit 1 and the telescopic end of the hydraulic gas spring 33 is hinged to the rigid arm 31, when the second holding unit 2 moves in the direction away from the first holding unit 1, the hydraulic gas spring 33 can provide resistance to the second holding unit 2, and when the second holding unit 2 loses external force, the hydraulic gas spring 33 can provide a rebound force to the second holding unit 2, thereby realizing the drawing and rebound of the arrowless bow.

[0034] Wherein, the hydraulic gas spring 33 can slow down the rotation of the rigid arm 31 by its own damping while providing the rebound force for the arrowless bow, and then drive the second holding unit 2 to slowly reset through the rigid string 32, thereby realizing the stable rebound of the arrowless bow, avoiding the problems of damage to the arrowless bow and injury to the archer caused by excessive rebound force and rebound speed, thereby effectively prolonging the service life of the arrowless bow, improving the safety of the arrowless bow, and further meeting the training needs of the archer.

[0035] At the same time, since the first holding unit 1 comprises the gyroscope 11, the arrowless bow can use the gyroscope 11 to position the space direction, and then simulate the aiming process of the arrowless bow, thereby enabling the archer to aim while drawing and rebounding with the arrowless bow, thereby simulating the real archery process and meeting the training needs of the archer.

[0036] It should be noted that the first holding unit 1 and the second holding unit 2 are used for the archer to hold, according to actual needs, the first holding unit 1 can be used for the left hand of the archer to hold, and the second holding unit 2 can be used for the right hand of the archer to hold, at this time, conversely, the first holding unit 1 can be used for the right hand of the archer to hold, and the second holding unit 2 can be used for the left hand of the archer to hold, which is not limited.

[0037] Wherein, the specific type of the first holding unit 1 and the second holding unit 2 can be set according to actual needs, which is not limited.

[0038] The gyroscope 11 can be an angular motion detection device that uses the momentum moment of a high-speed rotating body to sense the relative angular motion of the shell 1211 to the inertial space around one or two axes orthogonal to the rotation axis, and the specific type of the gyroscope 11 can be set according to actual needs, which is not limited. For example, the gyroscope 11 can be a six-axis gyroscope 11.

[0039] The number of the connecting units 3 can be set according to actual needs, and the number is not limited, for example, the connecting units 3 can be one, two, etc.

[0040] The rigid arm 31 serves as a part of the bow arm of the arrowless bow, and plays a supporting and driving role. The specific type of the rigid arm 31 can be set according to actual needs, and the specific type is not limited, for example, the rigid arm 31 can be a rigid structure close to an arc shape, and the rigid arm 31 can be made of light rigid materials such as aluminum alloy and carbon fiber.

[0041] The rigid string 32 serves as a part of the bow string of the arrowless bow, and plays a supporting and driving role. The specific type of the rigid string 32 can be set according to actual needs, and the specific type is not limited, for example, the rigid string 32 can be a rigid structure close to an arc shape, and the rigid string 32 can be made of light rigid materials such as aluminum alloy and carbon fiber.

[0042] Since the rigid arm 31 and the rigid string 32 are used for supporting and driving between the first holding unit 1 and the second holding unit 2, there is no elastic structure between the first holding unit 1 and the second holding unit 2 except the hydraulic gas spring 33, so that the drawing and rebound of the arrowless bow are more stable and controllable, thereby improving the safety of the arrowless bow and reducing the use threshold of the arrowless bow.

[0043] The rigid arm 31 and the rigid string 32 can be connected in various ways according to actual needs, and the connection mode is not limited, for example, the second end of the rigid arm 31 is provided with a notch, and the second end of the rigid arm 31 and the second end of the rigid string 32 are provided with openings penetrating the notch, and the bolt with a cover piece is sequentially inserted into the openings to realize the connection of the rigid arm 31 and the rigid string 32, thereby meeting the driving requirement between the rigid arm 31 and the rigid string 32.

[0044] The extension end of the hydraulic gas spring 33 provides resistance when extending, and provides elastic force when resetting, and the extension end of the hydraulic gas spring 33 provides rebound damping by using hydraulic oil when resetting. The specific type of the hydraulic gas spring 33 can be set according to actual needs, and the specific type is not limited, for example, the hydraulic gas spring 33 can include a cylinder body, a piston rod, a sliding block, an adjusting plate, a spring, etc., wherein the sliding block is slidingly arranged in the cylinder body, and the sliding block divides the cylinder body into a rod cavity and a rodless cavity, the sliding block is provided with a damping hole communicating the rod cavity and the rodless cavity, the rod cavity and the rodless cavity are provided with hydraulic oil, one end of the piston rod is slidingly inserted into the rod cavity and connected with the sliding block, the adjusting plate is slidingly arranged in the rodless cavity, and the spring is arranged between the adjusting plate and the sliding block.

[0045] Thus, when the piston rod as the telescopic end of the hydraulic gas spring 33 is extended, the piston rod drives the slider to move in the direction from the rodless cavity to the rod cavity, and then the hydraulic oil in the rod cavity enters the rodless cavity through the damping hole, and at the same time, the slider drives the spring to stretch, so that the extension of the piston rod has a certain resistance under the cooperation of the hydraulic oil and the spring; wherein, after the external force on the piston rod is removed, the spring resets and drives the slider to move in the direction from the rod cavity to the rodless cavity, and at the same time, the hydraulic oil in the rodless cavity enters the rod cavity through the damping hole, so that the reset of the piston rod has a certain resistance under the action of the hydraulic oil. Thus, the hydraulic gas spring 33 can provide resistance for the rotation of the rigid arm 31 and provide resilience and damping force for the reset of the rigid arm 31.

[0046] When the piston rod as the telescopic end of the hydraulic gas spring 33 is retracted, the piston rod drives the slider to move in the direction from the rod cavity to the rodless cavity, and then the hydraulic oil in the rodless cavity enters the rod cavity through the damping hole, and at the same time, the slider drives the spring to compress, so that the retraction of the piston rod has a certain resistance under the cooperation of the hydraulic oil and the spring; wherein, after the external force on the piston rod is removed, the spring resets and drives the slider to move in the direction from the rodless cavity to the rod cavity, and at the same time, the hydraulic oil in the rod cavity enters the rodless cavity through the damping hole, so that the reset of the piston rod has a certain resistance under the action of the hydraulic oil. Thus, the hydraulic gas spring 33 can provide resistance for the rotation of the rigid arm 31 and provide resilience and damping force for the reset of the rigid arm 31.

[0047] Wherein, according to actual needs, when the second holding unit 2 moves in the direction close to the first holding unit 1, the telescopic end of the hydraulic gas spring 33 can be in the extended state, and when the second holding unit 2 moves in the direction away from the first holding unit 1, the telescopic end of the hydraulic gas spring 33 is in the reset state, or, when the second holding unit 2 moves in the direction close to the first holding unit 1, the telescopic end of the hydraulic gas spring 33 can be in the retracted state, and when the second holding unit 2 moves in the direction away from the first holding unit 1, the telescopic end of the hydraulic gas spring 33 is in the reset state, and this is not limited.

[0048] Because the spring is arranged between the adjusting plate and the slider, the initial state of the spring can be adjusted by adjusting the position of the adjusting plate in the rodless cavity, and the resilience generated when the spring is compressed or stretched is different under different initial states of the spring, so that the resistance of the hydraulic gas spring 33 can be adjusted by adjusting the position of the adjusting plate, and then the training needs of different archery personnel can be met.

[0049] As Figure 4As shown in the drawings, in some embodiments, the connecting unit 3 further comprises a driving motor 34, the driving motor 34 is arranged on the first holding unit 1, and the driving motor 34 is in transmission connection with the pressure adjusting end of the hydraulic gas spring 33.

[0050] It can be understood that the driving motor 34 drives the pressure adjusting end of the hydraulic gas spring 33 to act, so as to adjust the pressure of the hydraulic gas spring 33, thereby adjusting the arch-drawing resistance of the arrowless bow, so that the arrowless bow can meet the different training needs of the archery personnel, thereby effectively improving the flexibility and versatility of the arrowless bow, and making the use of the arrowless bow more convenient.

[0051] It should be noted that the driving motor 34 is used to drive the pressure adjusting end of the hydraulic gas spring 33, and the specific type of the driving motor 34 can be set according to actual needs, and no limitation is made to this, for example, the driving motor 34 can be a telescopic motor, the telescopic rod of the driving motor 34 is connected with the adjusting plate of the hydraulic gas spring 33, and the driving motor 34 drives the adjusting plate of the hydraulic gas spring 33 to move in the rodless cavity, so as to realize the pressure adjustment of the hydraulic gas spring 33; the driving motor 34 can be a rotary motor, the rotary shaft of the driving motor 34 is connected with the adjusting plate through a screw rod, and the driving motor 34 drives the adjusting plate of the hydraulic gas spring 33 to move in the rodless cavity, so as to realize the pressure adjustment of the hydraulic gas spring 33.
