Description

Technical Field

[0001] The utility model relates to the technical field of sports training equipment, in particular to a hand shape correction manipulator. Background Art

[0002] In sports such as basketball, shooting hand shape is one of the key factors affecting the hit rate. However, many practitioners may encounter problems such as inaccurate finger and wrist movements and hand deviation when exerting force during training. If these irregular movements continue for a long time, it is easy to form a habit that is difficult to change, thus affecting the accuracy and effect of shooting. Therefore, correct shooting hand shape training is crucial to improving basketball skills.

[0003] The existing hand shape corrector is a product designed to assist in correcting hand movements during sports. It usually adopts the method of fixed connection of fingers, and uses straps to fix the key fingers involved in shooting together, so as to form correct muscle memory and deepen the athlete's understanding and mastery of the correct hand shape. However, this device can only bind several fingers involved in shooting to form a consistent movement, but cannot correct the standardization of the movement.

[0004] Existing hand correction manipulators mostly use pneumatic and motor drive. Pneumatically driven manipulators use air pressure changes to achieve finger bending and extension. The control lacks precise position and force feedback information, resulting in the movement of the manipulator's finger joints not being smooth enough, which to some extent affects the use of the manipulator. The motor drive drives the movement of the fingers through the rotation of the motor. In order to achieve multi-degree-of-freedom movement, some existing control methods install servos at the finger joints to achieve finger movement through the drive of the servos.

[0005] However, due to the large number of servos, this increases the burden on the wearer's hands, which may affect the effect of movement correction. In terms of transmission methods, manipulators usually adopt two forms: wire transmission and connecting rod transmission. Wire transmission manipulator fingers are favored for their light weight and compact space occupancy, but this design has limitations in load capacity, transmission efficiency and accuracy, and the flexibility of finger joints needs to be improved. Due to the rigid connecting rod design, the adaptability of connecting rod transmission manipulator fingers is relatively poor, and it is difficult to adapt to the grasping needs of objects of different sizes and shapes.

[0038] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0039] like Figure 1 and Figure 2 As shown, a hand correction manipulator in one embodiment of the utility model comprises:

[0040] Install the plate rack 1;

[0041] The finger component 2 includes two finger assemblies 20, each of the finger assemblies 20 includes an input unit 21 and two finger units 22 connected to the input unit 21;

[0042] The driving component 3 is arranged on the mounting plate frame 1 and includes two driving assemblies 31 . The two driving assemblies 31 are used to drive the input units 21 in the two finger assemblies 20 respectively.

[0043] Specifically, through the preset control mechanism, the wearer's hands are guided to complete stretching and bending movements, thereby achieving detailed correction of the wearer's shooting hand shape, simulating natural hand movements, and assisting the wearer to gradually form the correct shooting posture.

[0044] The above-mentioned hand correction manipulator uses a driving component 31 to drive two finger units 22 at the same time, which can effectively reduce the number of required driving motors 32, thereby reducing the burden on the wearer's hands and improving the movement correction effect.

[0045] In one embodiment, the finger unit 22 includes a first mechanism 23, a second mechanism 24 and a third mechanism 25 connected in sequence; the first mechanism 23 includes a first driving block 231, and the first driving block 231 is provided with a first hinge portion 234, a first connecting portion 235 and a first driven portion 236; the second mechanism 24 includes a second driving rod 241, a second connecting rod 242 and a first finger sleeve 243 arranged on the second driving rod 241; the third mechanism 25 includes a third connecting rod 251, a fourth connecting rod 252, a third finger rod 253, and a second finger sleeve 254 arranged on the third finger rod 253, and the third finger rod 253 is provided with a third connecting portion 256 and a third input portion 257; the first hinge portion 234, the second driving rod 241, the third connecting rod 251, and the third input portion 257 are connected in sequence; the first connecting portion 235, the second connecting rod 242, the fourth connecting rod 252, and the third connecting portion 256 are connected in sequence. In this way, the wearer passes his fingers through the second finger sleeve 254 and the first finger sleeve 243 in sequence, and utilizes their elasticity to fit tightly after being put on the fingers, thereby ensuring good cooperation between the device and the fingers; at the same time, the first mechanism 23, the second mechanism 24 and the third mechanism 25 imitate multiple joints of the fingers, thereby improving the accuracy of correction and enhancing the comfort of wearing.

[0046] In one embodiment, the driving assembly 31 includes a driving motor 32 fixedly arranged on the mounting plate frame 1, and a gear rack unit 33 driven by the driving motor 32; the gear rack unit 33 includes a transmission gear 331 arranged at the output end of the driving motor 32, and a transmission rack 332 meshing with the transmission gear 331; the transmission rack 332 is connected to the first driven part 236 of the first driving block 231. In this way, the driving force of the driving motor 32 is transmitted through the transmission gear 331 on the output shaft end thereof, and the transmission gear 331 and the transmission rack 332 are meshed and transmitted, and the gear rack unit 33 converts the rotational motion into its own horizontal linear motion, thereby ensuring the reliability and stability of the work, and being able to transmit a large power at the same time.

[0047] In one embodiment, the transmission rack 332 is connected to the first driven part 236 through the input unit 21 and the sliding unit 34 in sequence; the sliding unit 34 includes a sliding rod 341 fixedly connected to the mounting plate frame 1, a slider 342 sleeved on the sliding rod 341, and a sliding connecting rod 343; one end of the transmission rack 332 is connected to the slider 342; one end of the sliding connecting rod 343 is connected to the first driven part 236, and the other end is connected to the slider 342. In this way, the slider 342 drives the first driving block 231 to reciprocate as the transmission rack 332 moves on the mounting plate frame 1.

[0048] In one embodiment, the input unit 21 includes a mounting block 211 disposed on the slider 342, and a connecting shaft 212 connecting two mounting blocks 211. Thus, the two sliding units 34 are connected and driven by the connecting shaft 212, so that one driving assembly 31 drives two finger units 22 at the same time.

[0049] In one embodiment, the first driving block 231 is a triangular block, and the first hinge portion 234, the first connecting portion 235 and the first driven portion 236 are respectively arranged at three corners of the triangular block. In this way, the triangular block has a high structural strength and meets the use requirements.

[0050] In one embodiment, the connecting end of the second driving rod 241 is in a U-shaped structure. Thus, the U-shaped structure is used to avoid the gap between each driving rod and the connecting rod, thereby avoiding interference and ensuring that the overall structure can fully simulate the free movement state of the hand shape, thereby improving the accuracy of correction.

[0051] In one embodiment, the first finger sleeve 243 is a nitrile rubber finger sleeve. Nitrile rubber has excellent elasticity and wear resistance, which can ensure its normal use and withstand long-term friction without damage.

[0052] In one embodiment, the second driving rod 241 is provided with a second hinged portion 255 hinged to the fourth connecting rod 252. In this way, the second hinged portion 255 is used to limit the movable angle of the fourth connecting rod 252, which is beneficial to improve the structural strength.

[0053] In one embodiment, the connecting rods are connected by riveting, so that the riveting connection is simple and occupies a small space; at the same time, the connection strength meets the use requirements.

[0054] In one embodiment, the four finger units 22 are arranged in parallel. Specifically, the length of each rod of the four finger units 22 can be adjusted according to the actual finger length. In this way, by arranging the four finger units 22 in parallel, the free movement state of the hand shape can be fully simulated.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
