[0031] The wearable polishing system disclosed herein may include structures such as a strap assembly 100, an adjustment assembly 300, a balance assembly 500, and a support assembly 700.
[0032] When in use, the wearable polishing system disclosed herein can be worn on the human body through the shoulder strap component 100, thereby fixing the wearable polishing system to the human body and supporting the weight of the polishing machine 900 through the human body. As a result, the user will not feel fatigue when using the polishing machine for a long time.
[0033] An adjustment component 300 is disposed on the shoulder strap assembly 100 for adjusting the shoulder strap assembly 100 to adapt to different human bodies, thereby enabling the wearable polishing system of this disclosure to adapt to operators of different body types.
[0034] The balancing component 500 is disposed in the adjusting component 300 for balancing the grinders 900 of different weights. Moreover, the balancing component 500 of this disclosure can also ensure that the grinders 900 generate approximately the same overturning torque on the human body when they are in different positions.
[0035] The support assembly 700 is disposed on the balancing assembly 500, wherein the grinder 900 is mounted on the support assembly 700.
[0036] When the wearable polishing system with the above structure is in use, the synergistic effect of the components can effectively balance the gravity of the polisher and the overturning moment generated during polishing, reduce the physical burden on the operator when using the polisher, and solve the technical problems mentioned in the background art.
[0037] The following will describe the detailed structure of the wearable polishing system.
[0038] The sling assembly 100 disclosed herein includes a waist belt 101, a waist belt buckle 102, shoulder straps 103, a first side waist pad 105, and a second side waist pad 106.
[0039] The disclosed belt 101 is provided as one, and correspondingly, a belt buckle 102 is also provided. The belt buckle 102 is provided on the belt 101 and is used to adjust the length of the belt 101 and lock the belt 101 around the waist of the human body. In other words, the length of the belt 101 of the disclosed invention can be adjusted and locked according to the body shape of the human body through the belt buckle 102.
[0040] The first side waist pad 105 and the second side waist pad 106 are both provided on the waist belt 101 and can be adjusted in position relative to the waist belt 101.
[0041] Specifically, when the wearable polishing system of this disclosure is in use, the belt buckle 102 can be located in front of the human body, and the first waist side pad 105 and the second waist side pad 106 can be located on the two sides of the human body.
[0042] Additionally, the shoulder strap assembly 100 of this disclosure may also include a lumbar support pad 107 disposed on the waist belt 101. When the wearable sculpting system of this disclosure is in use, the lumbar support pad 107 may be located at the rear of the body.
[0043] Preferably, the lower back pad 107, the first side waist pad 105, and the second side waist pad 106 can all include foam sponge, thereby improving wearing comfort and lumbar support strength, as well as improving the stability of the shoulder strap assembly.
[0044] One end of the shoulder strap 103 is connected to the adjustment assembly 300, and the other end is connected to the back plate 104. In embodiments of this disclosure, two shoulder straps 103 can be provided, so that each shoulder strap 103 can correspond to one of the user's shoulders. A shoulder strap buckle can be provided in the middle of the shoulder strap 103 to adjust the length of the shoulder strap 103. In other words, the length of the shoulder strap 103 can be adjusted and locked according to the human body shape through the shoulder strap buckle to improve shoulder support strength. Each shoulder strap 103 can be provided with a shoulder strap pad, which can contact the human shoulder to improve the comfort of the user when using the wearable polishing system.
[0045] The two shoulder straps can be connected by a chest strap. This chest strap can be equipped with a buckle, which allows for adjustment and locking of the strap's length, thus improving chest support.
[0046] The back panel 104 is used to mount the adjustment assembly 300, specifically, to mount the slide rail 301 described below, thereby enabling the support force to be transmitted to the adjustment assembly when the user wears the back strap assembly 100. Preferably, the surface of the back panel 104 facing the human body is provided with an elongated groove for air circulation, ensuring the comfort of the user.
[0047] The adjustment assembly 300 disclosed herein includes a slide rail 301, a slider 302, a clamp 303, a slide table 304, a bidirectional screw 305, a bearing seat 306, a first adapter plate 307, and a second adapter plate 308, etc.
[0048] The slide rail 301 is mounted on the back panel 104 and is set approximately vertically; specifically, the slide rail 301 is fixed to the surface of the back panel 104 away from the human body, that is, the slide rail 301 is mounted on the outer surface of the back panel 104.
[0049] The slider 302 is slidably disposed on the slide rail 301; thus, the slider 302 of this disclosure can slide on the slide rail 301 to adjust the height of the polishing machine. Moreover, by adjusting the position of the slider 302, the height position of the back plate 104 relative to the back of the human body can be adjusted, which also helps to control the center of gravity of the entire wearable polishing system, thereby making the user more comfortable when using the wearable polishing system of this disclosure.
[0050] The clamp 303 is used to lock the slider 302 to the slide rail 301. Specifically, when the slider 302 is manually driven and moves along the slide rail 301 to the target position, the slider 302 can be locked together with the slide rail 301 by rotating the clamp 303, so that the slider 302 can be fixed relative to the slide rail 301.
[0051] The slide 304 is fixed to the slider 302; thus, the slide 304 can move up and down together with the slider 302. In a preferred embodiment, the slide 304 is located above the slider 302.
[0052] A bidirectional screw 305 is rotatably mounted on a slide 304; specifically, the bidirectional screw 305 is positioned approximately horizontally. That is, the bidirectional screw 305 is rotatably supported on the slide 304 by a bearing, and the bearing also restricts the bidirectional screw 305 from axial displacement relative to the slide 304. Furthermore, the bidirectional screw 305 of this disclosure can be driven to rotate by a handle or similar device. After the bidirectional screw 305 has rotated completely, it can be locked to the slide 304 by a locking structure, at which point the bidirectional screw 305 will be unable to slide relative to the slide 304. In one specific embodiment, this locking structure can be a brake device.
[0053] The bearing housing 306 is disposed on the slider 302; the bearing housing 306 of this disclosure can be formed as a shaft component, on which a bearing is sleeved, and the axis of the shaft component is perpendicular to the vertical direction (i.e., perpendicular to the length direction of the slide rail 301) and perpendicular to the axial direction of the bidirectional screw 305.
[0054] The first adapter plate 307 and the second adapter plate 308 are rotatably mounted on the bearing housing 306 via bearings, wherein the first adapter plate 307 and the second adapter plate 308 are arranged crosswise; thus, the first adapter plate 307 and the second adapter plate 308 are approximately X-shaped.
[0055] The upper end of the first adapter plate 307 is provided with a first sliding groove, the length direction of which is parallel to the length direction of the first adapter plate 307. The upper end of the second adapter plate 308 is provided with a second sliding groove, the length direction of which is parallel to the length direction of the second adapter plate 308.
[0056] The bidirectional screw 305 has a first nut 309 and a second nut 310 at its two ends, respectively. A first bearing is mounted on the first nut 309, and a second bearing is mounted on the second nut 310. When the bidirectional screw 305 is driven and rotated, the first nut 309 and the second nut 310 can approach or move away from each other. Furthermore, the first bearing can slide within a first sliding groove, and the second bearing can slide within a second sliding groove. Therefore, when the bidirectional screw 305 is driven to rotate, the angle between the first adapter plate 307 and the second adapter plate 308 can be changed. Correspondingly, in the vertical direction, the distance from the upper end to the lower end of the first adapter plate 307 can be changed, and the distance between the lower ends of the first adapter plate 307 and the second adapter plate 308 can be changed.
[0057] The adjustment assembly 300 also includes a first waist slide rail 311 and a second waist slide rail 312. The first waist slide rail 311 is disposed at the lower end of the first adapter plate 307, and the second waist slide rail 312 is disposed at the lower end of the second adapter plate 308. The first waist slide rail 311 is also fixedly connected to the first waist side pad 105, and the second waist slide rail 312 is fixedly connected to the second waist side pad 106.
[0058] Furthermore, the two shoulder straps 103 of this disclosure are respectively fixed to the first waist slide rail 311 and the second waist slide rail 312. Thus, when the adjustment component 300 of this disclosure is working, it can adjust the position and distance of the first waist slide rail 311 and the second waist slide rail 312, so that the first waist side pad and the second waist side pad can better fit the human body. It can also adjust the overall center of the entire wearable polishing system to improve the user experience.
[0059] The adjustment assembly 300 of this disclosure further includes a first movable locking device 313 and a second movable locking device 314. The first movable locking device 313 is lockable to the lower end of the first adapter plate 307 and slidably disposed on the first waist rail 311, thereby making the distance between the first waist rail 311 and the lower end of the first adapter plate 307 adjustable. Similarly, the second movable locking device 314 is lockable to the lower end of the second adapter plate 308 and slidably disposed on the second waist rail 312, thereby making the distance between the second waist rail 312 and the lower end of the second adapter plate 308 adjustable.
[0060] The adjustment assembly 300 disclosed herein also includes an end cap 315, which can be fixed to the bearing seat 306, thereby preventing the first adapter plate 307 and the second adapter plate 308 from falling off.
[0061] The balancing components 500 can be configured as two, which can have a symmetrical structure and are respectively disposed on the first waist slide rail 311 and the second waist slide rail 312.
[0062] Specifically, the balancing assembly 500 disclosed herein may include components such as a first rotating shaft moving sleeve 501, a first rear rotating shaft 502, a first front rotating shaft 503, a first upper parallel rod 504, a first lower parallel rod 505, a first adjusting spring 506, a first length adjuster 507, a first nut 508, and a first pull rope 509.
[0063] A first rotating shaft movable sleeve 501 is disposed on a first waist slide rail 311. The first rotating shaft movable sleeve 501 can be adjusted in position relative to the first waist slide rail 311, and after the position adjustment is completed, the first rotating shaft movable sleeve 501 can be fixed to the first waist slide rail 311, thereby accommodating the operation of the balance component 500 by people of different body types. A first rear rotating shaft 502 is rotatably disposed on the first rotating shaft movable sleeve 501, wherein the rotation axis of the first rear rotating shaft 502 is set approximately vertically. The rotation axis of the first front rotating shaft 503 is set parallel to the rotation axis of the first rear rotating shaft.
[0064] One end of the first upper parallel rod 504 is rotatably mounted on the upper end of the first rear rotating shaft 502 via the first upper rotating shaft 510, and the other end of the first upper parallel rod 504 is rotatably mounted on the upper end of the first front rotating shaft 503 via the first upper hinge shaft 511. The axis of the first upper rotating shaft 510 and the axis of the first upper hinge shaft 511 are parallel and horizontal.
[0065] One end of the first lower parallel rod 505 is rotatably mounted on the lower end of the first rear rotating shaft 502 via the first lower rotating shaft 512, and the other end of the first lower parallel rod 505 is rotatably mounted on the lower end of the first front rotating shaft 503 via the first lower hinge shaft 513. The axis of the first lower rotating shaft 512 and the axis of the first lower hinge shaft 513 are parallel and horizontal. In other words, the axes of the first lower rotating shaft 512, the first lower hinge shaft 513, the first upper rotating shaft 510, and the first upper hinge shaft 511 of this disclosure are all parallel.
[0066] Thus, the first rear rotating shaft 502, the first front rotating shaft 503, the first upper parallel rod 504, and the first lower parallel rod 505 of this disclosure can form a parallelogram mechanism.
[0067] One end of the first adjusting spring 506 is disposed on the first upper hinge shaft 511, and the other end of the first adjusting spring 506 is disposed on the first pull rope 509; the first length adjuster 507 is rotatably disposed on the first lower parallel rod 505, wherein the first length adjuster 507 is a threaded shaft; the first nut 508 is rotatably disposed on the first length adjuster 507, so that when the first length adjuster 507 is driven to rotate, the first nut 508 can move along the length direction of the first length adjuster 507; one end of the first pull rope 509 is fixed to the first nut 508, and the other end of the first pull rope 509 is partially wound around the first rear rotating shaft 502 and connected to the other end of the first adjusting spring 506.
[0068] Therefore, when the first length adjuster 507 is manually driven to rotate, the first nut 508 can move along the length direction of the first length adjuster 507, thereby changing the extension length of the first adjusting spring 506. Accordingly, the first adjusting spring 506 can provide different adjusting forces. Thus, the balancing assembly 500 of this disclosure can balance grinders of different weights by means of the different adjusting forces provided by the first adjusting spring 506.
[0069] The first lower parallel rod 505 of this disclosure is also provided with a scale, which is used to indicate the length of the first adjusting spring 506 so that the operator can quickly select the required length according to the different weights of the grinder.
[0070] The balancing assembly 600 disclosed herein also includes components such as a second rotating shaft moving sleeve, a second rear rotating shaft 602, a second front rotating shaft 603, a second upper parallel rod 604, a second lower parallel rod 605, a second adjusting spring 606, a second length adjuster, a second nut, and a second pull rope.
[0071] The second rotating shaft movable sleeve is disposed on the second waist slide rail 312. The position of the second rotating shaft movable sleeve relative to the second waist slide rail 312 can be adjusted, and after the position adjustment is completed, the second rotating shaft movable sleeve can be fixed to the second waist slide rail 312, thereby accommodating the operation of the balance component 600 by people of different body types. The second rear rotating shaft 602 is rotatably disposed on the second rotating shaft movable sleeve, wherein the rotation axis of the second rear rotating shaft 602 is arranged approximately vertically. The rotation axis of the second front rotating shaft 603 is arranged parallel to the rotation axis of the second rear rotating shaft.
[0072] One end of the second upper parallel rod 604 is rotatably mounted on the upper end of the second rear rotating shaft 602 via the second upper rotating shaft, and the other end of the second upper parallel rod 604 is rotatably mounted on the upper end of the second front rotating shaft 603 via the second upper hinge shaft. The axis of the second upper rotating shaft is parallel to the axis of the second upper hinge shaft and is horizontal.
[0073] One end of the second lower parallel rod 605 is rotatably mounted on the lower end of the second rear rotating shaft 602 via a second lower rotating shaft, and the other end of the second lower parallel rod 605 is rotatably mounted on the lower end of the second front rotating shaft 603 via a second lower hinge shaft. The axis of the second lower rotating shaft and the axis of the second lower hinge shaft are parallel and horizontal. In other words, the axes of the second lower rotating shaft, the second lower hinge shaft, the second upper rotating shaft, and the second upper hinge shaft of this disclosure are all parallel.
[0074] Therefore, the second rear rotating shaft 602, the second front rotating shaft 603, the second upper parallel rod 604 and the second lower parallel rod 605 of this disclosure can form a parallelogram mechanism.
[0075] One end of the second adjusting spring 606 is disposed on the second upper hinge shaft, and the other end of the second adjusting spring 606 is disposed on the second pull rope; the second length adjuster is rotatably disposed on the second lower parallel rod 605, wherein the second length adjuster is a threaded shaft; the second nut is rotatably disposed on the second length adjuster, so that when the second length adjuster is driven to rotate, the second nut can move along the length direction of the second length adjuster; one end of the second pull rope is fixed to the second nut, and the other end of the second pull rope is partially wound around the second rear rotating shaft 602 and connected to the other end of the second adjusting spring 606.
[0076] Therefore, when the second length adjuster is manually driven to rotate, the second nut can move along the length direction of the second length adjuster, thereby changing the extension length of the second adjusting spring 606. Accordingly, the second adjusting spring 606 can provide different adjusting forces. Thus, the balancing assembly 600 of this disclosure can balance grinders of different weights by means of the different adjusting forces provided by the second adjusting spring 606.
[0077] The second lower parallel rod 605 of this disclosure is also provided with a scale, which is used to indicate the length of the second adjusting spring 606 so that the operator can quickly select the required length according to the different weights of the grinders.
[0078] The bracket assembly disclosed herein may include components such as a first connecting rod 701, a second connecting rod 702, a handle shaft 703, a U-shaped frame 704, a first decoupling guide rail 705, a second decoupling guide rail 706, a first handle 707, and a second handle 708.
[0079] The first connecting rod 701 is rotatably mounted on the first front pivot 503; the second connecting rod 702 is rotatably mounted on the second front pivot 603; the other ends of both the first connecting rod 701 and the second connecting rod 702 are mounted on the handle pivot 703, wherein the axis of rotation of the handle pivot 703 is vertical. In this configuration, the first connecting rod 701, the second connecting rod 702, and the balancing assembly 500 together provide three degrees of freedom for the grinder.
[0080] The U-shaped frame 704 includes a crossbeam and a first side and a second side fixed to the two ends of the crossbeam; wherein, the middle part of the crossbeam is fixed to the handle pivot 703; thereby, by rotating the U-shaped frame 704 around the handle pivot 703, one degree of rotational freedom of the grinder is realized.
[0081] The first decoupling guide rail 705 is rotatably disposed on the first side; the second decoupling guide rail 706 is rotatably disposed on the second side; the first decoupling guide rail 705 and the second decoupling guide rail 706 have the same axis of rotation, and the axis of rotation of the first decoupling guide rail 705 and the second decoupling guide rail 706 is perpendicular to the axis of rotation of the handle shaft 703.
[0082] One side of the grinder is fixed to the first decoupling guide rail 705, and the other side is fixed to the second decoupling guide rail 706. Moreover, the rotation axis of the grinder is perpendicular to the rotation axis of the first decoupling guide rail 705 and the second decoupling guide rail 706. Thus, the grinder of this disclosure has two rotational degrees of freedom when it is working.
[0083] The first handle 707 is disposed on the first decoupling guide rail 705; the second handle 708 is disposed on the second decoupling guide rail 706. More preferably, bullseye bearings may be installed on the first handle 707 and the second handle 708, which are disposed in the grooves of the first decoupling guide rail 705 or the second decoupling guide rail 706, thereby preventing the torque around the axis generated during grinding from being transmitted to the arm.
[0084] In operation, the wearable polishing system disclosed herein first involves fitting the shoulder strap assembly onto the upper body according to human dimensions. The positions of the side waist pads and back plate are adjusted using a slide table, bidirectional screw, and other structures to select the three pressure points. The adjustment assembly is then locked using a clamp and an axial locking device (moving locking device). The lengths of each component of the shoulder strap assembly are checked to ensure a secure fit against the body. Next, the rotating pivot sleeve is inserted into the waist slide rail and adjusted to the appropriate position, then locked using the moving locking device. Following this, the weight of the polishing machine is measured, and the machine is mounted on the U-shaped frame. Based on the measured weight, the adjusting spring is adjusted to the appropriate position using a length adjuster, completing the entire installation. Finally, polishing begins.
[0085] The wearable polishing system of the present invention has the following beneficial effects: 1) The device boasts excellent overall stability and adaptability. The shoulder strap assembly ensures the adjustable wearable unit is securely fixed to the human body; 2) The adjustment component can adjust the position of the three pressure points in the device, such as the two side waist pads and the back plate, on the human body to ensure that the pressure points can adapt to different body shapes; 3) The device boasts efficient gravity balance. It adapts to grinders of varying weights via an adjustable spring (zero-free-length adjustment spring) and length adjuster. The parallelogram structure ensures the stability of the overturning moment generated by the grinder's weight.
[0086] 4) High flexibility of the device. The design of the multi-degree-of-freedom support assembly improves the flexible movement and rotation of the grinder, ensuring that the device meets the requirements of the complete grinding process.
[0087] 5) The device is highly safe. The design of various pads enhances comfort and breathability, while various straps ensure device stability and safety during grinding operations.
[0088] 6) The device has good compatibility. The device can balance the gravity generated by grinders of different weights.
