CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to Chinese Patent Application No. 202520207390.3, filed on Feb. 10, 2025, which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of archery accessories, and in particular to a release aid with a 360-degree rotatable draw weight measurement mechanism.BACKGROUND

[0003] A bow and arrow release aid is an indispensable accessory for a compound bow. The bow and arrow release aid is mainly used for pulling a bowstring, prevents direct contact between fingers and the bowstring to avoid conditions of blisters and abrasion injury on fingers, and achieves protection and assistance effects. The compound bow delivers greater propulsion than traditional bows. Especially for novice users, selecting a compound bow with an appropriate draw weight value is essential to enhance user experience and ensure safety. Dedicated draw weight measurement instruments exist commercially, but these devices are typically bulky and inconvenient to transport, with complex measurement procedures that hinder novice users' ability to perform on-demand measurement.

[0004] To resolve these technical issues, Chinese Invention Patent No. 202421330560.9 titled “Bow and Arrow Release Aid with Draw Weight Measurement Mechanism” was developed.

At the same time, when the force direction and the force contact point change, the sensor can output a stable signal without affecting the final measurement result. This solves the technical problems of existing archery release aids where, when the force direction and the force contact point change, the sensor signal becomes unstable, leading to significant errors in the final measurement data, and the clamping portion cannot achieve 360-degree rotation relative to the housing.BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In use, by pressing the control block 7, the control block 7 pushes the ball-headed push rod 13 to move forward, the ball head 131 compresses the spring 9 and enables the jaw blocks 4 to be open. Compared with the above embodiments, this embodiment eliminates the steel ball 10 assembly, thereby reducing overall manufacturing cost.

[0056] Based on the above, the present disclosure has the following principle and beneficial effects:

[0057] The force sensor 2 is fixedly mounted in the housing 1. The clamping portion 3 is disposed at one end of the housing 1, and a pair of jaw blocks 4 configured to open and close are disposed on the clamping portion 3.

At the same time, the transmission assembly 14 configured to control the opening and closing of the jaw blocks 4 is disposed in the housing 1. In use, a bowstring is clamped through the jaw blocks 4. After the bowstring is tensioned, force may be generated on the jaw blocks 4. Since the jaw blocks 4 and the clamping portion 3 are relatively fixed, and the clamping portion 3 is connected to the force sensor 2 through the connecting assembly 15, this force may be transferred to the force sensor 2. Then, the force sensor 2 converts the force into a millivolt signal. Finally, the millivolt signal is received by the display device 5, converted into a draw weight value, and displayed.

[0058] The rotatable clamping portion 3 is disposed at one side of the housing 1, enabling the clamping portion 3 with the jaw blocks 4 to achieve 360-degree rotation relative to the housing 1. This allows for more convenient use of the release aid.

[0059] Through the above manner, the jaw blocks 4 can freely rotate 360 degrees. Additionally, when the force direction and the force contact point change, the signal output by the force sensor remains stable without affecting the final measurement result. This solves the technical problems of existing archery release aids where, when the force direction and the force contact point change, the sensor signal becomes unstable, leading to significant errors in the final measurement data, and the clamping portion cannot achieve 360-degree rotation relative to the housing.

[0060] The foregoing descriptions are merely preferred embodiments of the present disclosure, and the patent scope of the present disclosure is not limited thereto. All equivalent structural transformations made according to the content of the specification and accompanying drawings of the present disclosure, or the direct or indirect application of the present disclosure in other related technical fields under its inventive concept, shall fall within the patent protection scope of the present disclosure.

[0055] In use, by pressing the control block 7, the control block 7 pushes the ball-headed push rod 13 to move forward, the ball head 131 compresses the spring 9 and enables the jaw blocks 4 to be open. Compared with the above embodiments, this embodiment eliminates the steel ball 10 assembly, thereby reducing overall manufacturing cost.

[0056] Based on the above, the present disclosure has the following principle and beneficial effects:

[0057] The force sensor 2 is fixedly mounted in the housing 1. The clamping portion 3 is disposed at one end of the housing 1, and a pair of jaw blocks 4 configured to open and close are disposed on the clamping portion 3. The connecting assembly 15 is disposed between the clamping portion 3 and the force sensor 2. At the same time, the transmission assembly 14 configured to control the opening and closing of the jaw blocks 4 is disposed in the housing 1. In use, a bowstring is clamped through the jaw blocks 4. After the bowstring is tensioned, force may be generated on the jaw blocks 4. Since the jaw blocks 4 and the clamping portion 3 are relatively fixed, and the clamping portion 3 is connected to the force sensor 2 through the connecting assembly 15, this force may be transferred to the force sensor 2. Then, the force sensor 2 converts the force into a millivolt signal. Finally, the millivolt signal is received by the display device 5, converted into a draw weight value, and displayed.

[0058] The rotatable clamping portion 3 is disposed at one side of the housing 1, enabling the clamping portion 3 with the jaw blocks 4 to achieve 360-degree rotation relative to the housing 1. This allows for more convenient use of the release aid.

[0059] Through the above manner, the jaw blocks 4 can freely rotate 360 degrees. Additionally, when the force direction and the force contact point change, the signal output by the force sensor remains stable without affecting the final measurement result. This solves the technical problems of existing archery release aids where, when the force direction and the force contact point change, the sensor signal becomes unstable, leading to significant errors in the final measurement data, and the clamping portion cannot achieve 360-degree rotation relative to the housing.

[0060] The foregoing descriptions are merely preferred embodiments of the present disclosure, and the patent scope of the present disclosure is not limited thereto. All equivalent structural transformations made according to the content of the specification and accompanying drawings of the present disclosure, or the direct or indirect application of the present disclosure in other related technical fields under its inventive concept, shall fall within the patent protection scope of the present disclosure.
