Detailed Description

Referring to fig. 1 and fig. 2, fig. 1 and fig. 2 are a perspective view and an exploded view of a wearable power-saving accessory according to an embodiment of the present invention. The wearable labor-saving assistive device 100 of the present embodiment includes a connecting seat 110, an acting arm 120, a first adjusting mechanism 130, an elastic member 140, a second adjusting mechanism 150, and an assembling component 160. The connecting base 110 is configured to be fixed to the waist and abdomen of a human body through, for example, a band. In one embodiment, the connecting seat 110 may be a disk shape to be conveniently attached to the waist or abdomen of a human body. The binding band is inserted through the connecting base 110 to fix the connecting base 110 to the human body. In one example, the strap may be a velcro design or an adjustable length strap design.

As shown in fig. 1 and 2, one end of the acting arm 120 is pivotally disposed on the connecting base 110, and an included angle θ is formed between the acting arm 120 and the connecting base 110. The resilient member 140 is connected between the connecting base 110 and the acting arm 120 and configured to provide a resilient force when the acting arm 120 is stressed. In one embodiment, a shaft seat 111 is disposed on the connecting seat 110, and the shaft seat 111 is disposed on the connecting seat 110 through the quick release structure 200. The action arm 120 is pivoted on the axle seat 111 and can pivot relative to the axle seat 111. Fig. 3 is a schematic view of a device of a quick release structure according to an embodiment of the invention. The quick release structure 200 includes a shaft 210, a pin 220 and a trigger 230. The shaft rod 210 is disposed on the connecting seat 110, and the shaft seat 111 is sleeved on the shaft rod 210 through the shaft hole 111 a. The shaft 210 has a slot 211, and the latch 220 is inserted into the shaft seat 111 from the side of the shaft seat 111. The trigger 230 is coupled to the latch 220 and configured to rotate the latch 220. The surface of the pin 220 has a slot 221, and when the slot 221 of the pin 220 is aligned with the slot 211 of the shaft 210, the pin 220 is not coupled with the shaft 210, and the shaft seat 111 is not fixed on the connecting seat 110. When the trip 230 is rotated to locate a portion of the latch 220 in the slot 211, the latch 220 is engaged with the shaft 210, so that the shaft seat 111 is fixed on the connecting seat 110.

Referring to fig. 2 and fig. 4, fig. 4 is a schematic cross-sectional view illustrating a wearable power-saving accessory according to an embodiment of the invention. In the present embodiment, the shaft seat 111 has a first pivot hole 111b and a second pivot hole 111 c. The action arm 120 includes a first housing 121 and a second housing 122, and the first housing 121 and the second housing 122 are substantially U-shaped housings and are disposed opposite to each other. The first housing 121 has a first end 121a and a second end 121b opposite to each other, and the second housing 122 also has a first end 122a and a second end 122b opposite to each other. The first end 121a of the first housing 121 is pivoted to the first pivot hole 111b of the shaft seat 111, and the first end 122a of the second housing 122 is pivoted to the second pivot hole 111c of the shaft seat 111.

In the present embodiment, the first adjusting mechanism 130 is connected between the acting arm 120 and the connecting base 110, and the first adjusting mechanism 130 is configured to adjust the included angle θ. The first adjusting mechanism 130 includes a knob 131 and a fixing base 132. The fixed seat 132 is fixed to the action arm 120. The knob member 131 is screwed into the fixing seat 132 and the bottom end of the knob member 131 is pressed against the surface of the acting arm 120. Therefore, the rotation of the knob 131 drives the action arm 120 to pivot relative to the connecting base 110, so as to adjust the included angle θ (i.e., the lifting angle of the action arm 120).

As shown in fig. 2 and 4, in the present embodiment, the elastic member 140 is connected between the connecting seat 110 and the acting arm 120, and the elastic member 140 is configured to provide a resilient force when the acting arm 120 is stressed. Specifically, as shown in fig. 4, the elastic member 140 is disposed between the first casing 121 and the second casing 122. The elastic member 140 has a first end 141 and a second end 142 opposite to each other, and the first end 141 of the elastic member 140 is pivoted on the first pivot hole 111b of the shaft seat 111.

The second adjusting mechanism 150 is connected to the second end 142 of the elastic member 140 and configured to adjust the resistance of the elastic member 140. The second adjusting mechanism 150 includes a base 151, a pull rod 152 and a knob 153. The base 151 is disposed on the second end 142 of the resilient member 140. One end of the pull rod 152 is disposed on the base 151, and the other end of the pull rod 152 extends out of the acting arm 120 and is screwed into the knob member 153. The knob 153 is mounted on the action arm 120 through the base 154, and the knob 153 is configured to drive the pull rod 152 to move in conjunction with the base 151, so as to stretch or compress the elastic member 140, thereby adjusting the resistance of the elastic member 140.

With continued reference to fig. 2 and 4, the mounting assembly 160 is pivotally mounted to the other end of the arm 120 and is configured for mounting an agricultural implement thereto. In the present embodiment, the assembling component 160 includes a magnetic connecting base 161, a connecting rod 162 and a mounting base 163. The magnetic connecting base 161 has a first pivot hole 161a and a second pivot hole 161b, the second end 121b of the first housing 121 is pivoted on the first pivot hole 161a of the magnetic connecting base 161, and the second end 122b of the second housing 122 is pivoted on the second pivot hole 161b of the magnetic connecting base 161. The top end of the connecting rod 162 is attracted to the magnetic connecting base 161 through magnetic force, and the mounting base 163 is disposed at the bottom end of the connecting rod 162. Wherein the mounting block 163 may be adapted to mount an agricultural implement, such as a tea-leaf picker, thereto. In one example, the magnetic attraction between the connecting rod 162 and the magnetic coupling base 161 is about 20 kg, so that the mounting assembly 160 can bear the weight of a common agricultural implement in a normal operation mode. When the user is not working properly or falls down, the force applied to the mounting base 163 is greater than 20 kg, and the connecting rod 162 is separated from the magnetic connecting base 161, so as to ensure the safety of the user. In one embodiment, a universal joint 164 is provided between the connecting rod 162 and the mounting base 163 to allow the user to more flexibly operate the agricultural implement.

Thus, the user can use the mounting block 163 to clip or otherwise secure the mounting block 163 to the agricultural implement (e.g., to the grip or handle of the tea plucker) and then use the strap to secure the wearable labor-saving assistive device 100 to the waist. Then, the user can change the included angle θ between the acting arm 120 and the connecting seat 110 through the first adjusting mechanism 130 and adjust the resistance of the elastic member 140 through the second adjusting mechanism 150. For example, when the agricultural implement is heavy, the first adjustment mechanism 130 can lift the action arm 120, and the second adjustment mechanism 150 can compress the elastic member 140 to generate a larger supporting force and a larger buffering force for the elastic member 140, so as to reduce the force required by the user to lift or operate the agricultural implement, thereby assisting the user to take the agricultural implement and achieving the effects of saving labor and facilitating operation.

The wearable labor-saving assistive device can adjust the auxiliary operating angle and resistance according to the body shapes of different users and the weight of the agricultural machine to be taken, so as to assist the users to operate the agricultural machine more easily.
