Non-compensating anti-shake elbow pads

Abstract

The present invention discloses a non-compensating anti-shake elbow protector. In the non-compensating anti-shake elbow protector, not only a connecting mechanism is arranged between the forearm wrapping part and the upper arm wrapping part, but also a power assisting mechanism is configured, wherein the power assisting mechanism includes a shifting module and a supporting module. Before the user's arm is ready to make different movements, the shifting module is switched to the corresponding gear position, which can provide auxiliary support for the movement of the elbow joint, thereby reducing the stress burden of the elbow joint and the degree of arm shaking. At the same time, a first elastic element and a second elastic element are arranged to be connected to the elbow protector mechanism. When the user's arm flexes and extends, the first elastic element and the second elastic element can be retracted and contracted accordingly, thereby offsetting the axial movement between the elbow protector mechanism and the arm, and ensuring the fixation of the relative position of the elbow protector mechanism and the arm. This invention is used in the field of sports assisting equipment.

[0026] Reference Figure 1 , Figure 2 The non-compensating anti-shake elbow protector of an embodiment of the present invention includes an elbow protector mechanism, a connecting mechanism 2 and a power assisting mechanism 3, wherein the elbow protector mechanism has a forearm wrapping portion 11 and an upper arm wrapping portion 12, the connecting mechanism 2 and the power assisting mechanism 3 are both installed between the forearm wrapping portion 11 and the upper arm wrapping portion 12, and the connecting mechanism 2 and the power assisting mechanism 3 are symmetrically arranged on both sides of the forearm wrapping portion 11.

[0027] Specifically, the power assist mechanism 3 has a connected shift module 31 and a support module 32, the support module 32 includes a support member 321 and a second elastic element 322 connected to the support member 321 at one end. At the same time, at least one end of the connecting mechanism 2 is configured with a first elastic element 4, and the first elastic element 4 and the second elastic element 322 are both connected to the elbow protection mechanism.

[0028] According to the non-compensatory anti-shake elbow protector of an embodiment of the present invention, not only a connecting mechanism 2 is set between the forearm wrapping part 11 and the upper arm wrapping part 12, but also a power assisting mechanism 3 is configured, wherein the power assisting mechanism 3 includes a shifting module 31 and a supporting module 32. Before the user's arm is ready to make different movements, by switching the shifting module 31 to the corresponding gear, it can play an auxiliary supporting role in the movement of the elbow joint, thereby reducing the force burden of the elbow joint and reducing the degree of arm shaking; at the same time, a first elastic element 4 and a second elastic element 322 are set to be connected to the elbow protector mechanism. When the user's arm flexes and extends, the first elastic element 4 and the second elastic element 322 can expand and contract accordingly, thereby offsetting the axial movement between the elbow protector mechanism and the arm, and ensuring the fixation of the relative position of the elbow protector mechanism and the arm.

[0029] In some embodiments of the present invention, the connecting mechanism 2 comprises a small arm connecting rod 21 provided on the small arm wrapping portion 11 and a large arm connecting rod 22 provided on the large arm wrapping portion 12, wherein the large arm connecting rod 22 is hingedly connected to the small arm connecting rod 21. Specifically, as Figure 2As shown, the upper arm connecting rod 22 and the lower arm connecting rod 21 are connected by a connecting shaft, and there is a single-axis transmission between the two. Such a setting can not only reduce the size of the transmission connection part, but also help to reduce the weight of the connecting mechanism 2, thereby achieving the purpose of lightweight. Furthermore, the first elastic element 4 is a spring, one end of which is fixed to the end of the lower arm connecting rod 21, and the other end is connected to the lower arm wrapping part 11; in order to prevent the telescopic movement of the first elastic element 4 from being disturbed by the external environment and to ensure that its telescopic movement can proceed normally, a fixed cover shell is provided on the lower arm wrapping part 11 for the end of the first elastic element 4 to be inserted and fixed. It should be noted that the number of the first elastic element 4 is not limited to one, and two or more can be provided depending on the actual situation.

[0030] In some embodiments of the present invention, the shift module 31 is fixed to the upper arm wrapping portion 12, and the support module 32 is connected to the lower arm wrapping portion 11; in this case, the second elastic element 322 is a spring, one end of which is connected to the support member 321 and the other end is fixed to the lower arm wrapping portion 11. Figure 3 , Figure 4 The shift module 31 of this embodiment includes a casing, a driving assembly installed on the casing, a shift shaft 313 and a gear assembly 314 arranged inside the casing, and the driving assembly is connected to the shift shaft 313 by driving; more specifically, the casing is composed of an upper casing and a lower casing 3111 connected by splicing, the lower casing is connected to the upper arm wrapping part 12, and the middle part of the lower casing forms a receiving chamber; the driving assembly includes a motor 3121, a driving gear 3122 installed on the output shaft of the motor and a driven gear 3123 meshing with the driving gear, the motor is fixed to the outside of the lower casing, the driving gear and the driven gear are arranged in the receiving chamber, the shift shaft 313 extends into the receiving chamber and is fixed on the driven gear, when the driven gear rotates, it can drive the shift shaft 313 to rotate, thereby achieving the purpose of switching gears. Installing the motor on the outside of the casing in this way can provide convenience for the user. When the user needs to replace the motor, there is no need to disassemble the entire power assist mechanism 3, which simplifies the operation steps and avoids the internal power assist mechanism 3 from being damaged by human factors.

[0031] Furthermore, in order to enable the motor to be started at any time, a rechargeable capacitor is provided in the present embodiment to be connected to the motor, and the motor is powered by the rechargeable capacitor; at the same time, in order to allow the user to clearly know the power usage of the rechargeable capacitor, a power display light connected to the rechargeable capacitor by an electric wire is installed on the casing.

[0032] More specifically, in this specific embodiment, the gear assembly 314 includes an internal gear 3141 and a center shell 3142 arranged in the middle of the internal gear 3141, wherein the support member 321 is connected to the internal gear 3141, and one end of the shift shaft 313 extends from the surface of the center shell 3142 into the center shell 3142. Furthermore, the portion of the shift shaft 313 located in the center shell 3142 is equipped with a cam, and the side surface of the center shell 3142 is slidably nested with the forward braking structure 3143, the reverse braking structure 3144, the deceleration structure 3145 and the neutral structure 3146; when the cam rotates, the forward braking structure 3143 or the reverse braking structure 3144 or the deceleration structure 3145 can be respectively pushed out to connect with the internal gear 3141, thereby switching the current gear of the shift module 31 to the forward gear, the reverse gear and the deceleration support gear.

[0033] like Figure 5 As shown, the forward braking structure 3143 and the reverse braking structure 3144 both include a brake rod, and the ends of the two brake rods close to the inner gear 3141 are formed with inclined surfaces, and the two inclined surfaces face opposite directions. When the cam pushes out the brake rod of the forward braking assembly or the reverse braking assembly, the end of the brake rod is embedded in the tooth groove of the inner gear 3141 and meshes with the inner gear 3141. Under the action of the inclined surface, the inner gear 3141 can be prevented from rotating, thereby preventing unpowered gear shifting without the user's knowledge.

[0034] Further, the deceleration structure 3145 includes a rod member No. 1 and a sliding tooth No. 1 fixed at the end of the rod member No. 1, a friction sleeve is sleeved on the sliding tooth No. 1, and the inner wall of the internal gear 3141 is provided with a slot for the sliding tooth No. 1 to be inserted and slid. The friction sleeve is made of rubber or other damping materials. When the sliding tooth No. 1 enters the slot, the friction sleeve is in contact with the slot wall of the slot, and friction resistance is generated between them, so that the movement speed of the internal gear 3141 can be slowed down when the internal gear 3141 rotates. More specifically, the neutral structure 3146 of this embodiment has a rod member No. 2 and a sliding tooth No. 2 provided at the end of the rod member No. 2, wherein, in order to prevent the sliding tooth No. 2 from meshing with the internal gear 3141 and ensure that no relative force is generated between the neutral structure 3146 and the internal gear 3141, the tooth tip width of the sliding tooth No. 2 is set to be greater than the spacing between adjacent tooth tips of the internal gear 3141. More specifically, an annular groove is provided in the middle of the detent rod, the first rod and the second rod respectively, and a coil spring is wound around the outside of the annular groove as a reset element, and each coil spring is connected to the center shell 3142; when the ejection force of the cam on the detent rod, the first rod and the second rod is cancelled, the detent rod, the first rod and the second rod can be automatically retracted under the action of the deformation recovery of the coil spring, thereby avoiding the situation of incomplete gear switching. Figure 5In this specific embodiment, the central shell 3142 is a cubic structure, and the forward braking structure 3143, the reverse braking structure 3144, the deceleration structure 3145 and the neutral structure 3146 are sequentially arranged at the corners where the high line of the central shell 3142 is located, and the connecting lines at both ends of the forward braking structure 3143, the reverse braking structure 3144, the deceleration structure 3145 and the neutral structure 3146 are all located on the same plane.

[0035] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the forearm wrapping part 11 and the upper arm wrapping part 12 are both arc-shaped wrapping parts, and the cross-section of each arc-shaped wrapping part is U-shaped, and a through hole 15 is respectively provided in the middle of each arc-shaped wrapping part; the edges of each through hole 15 are chamfered. The provision of the through hole 15 can not only allow the forearm wrapping part 11 and the upper arm wrapping part 12 to better adapt to the changes in the arm muscle lines during the flexion and extension rotation of the elbow joint, but also help to reduce the weight of the forearm wrapping part 11 and the upper arm wrapping part 12, and improve the comfort of the user when using it. Furthermore, two pairs of strap clamping shafts 13 are symmetrically arranged on both sides of each arc-shaped wrapping part, and a strap 14 is connected between the strap clamping shafts 13 of the same pair. In order to allow the user to adjust the use length of the strap 14 according to the size of his own arm, a buckle is respectively installed on each strap 14. The provision of the buckle also improves the versatility of the accompanying rotation device. Furthermore, in order to better improve the wearing comfort of the user and reduce the pressure caused by the straps 14 on the user's arms, each strap 14 of the present embodiment is an elastic strap.

[0036] More specifically, the forearm wrapping part 11 and the upper arm wrapping part 12 are both made of ABS plastic, which is lightweight, non-toxic and tasteless. The products made of ABS plastic are lightweight and safe, and can reduce the burden on human arms. The upper arm connecting rod 22 and the forearm connecting rod 21 are made of 6061 aluminum alloy to ensure strength and improve corrosion resistance.

[0037] Of course, the design and creation of the present invention is not limited to the above-mentioned implementation modes. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
