Description

Technical Field

[0001] The invention belongs to the technical field of all-terrain vehicles and relates to a connection assembly, in particular to a connection assembly for an all-terrain vehicle. Background Art

[0002] An all-terrain vehicle is a vehicle that can travel on any terrain. It can travel freely on terrain that is difficult for ordinary vehicles to maneuver. It can travel on beaches, riverbeds, forest roads, streams, and harsh desert terrain. The body coverings on an all-terrain vehicle are used to protect the power components and transmission components of the all-terrain vehicle.

[0003] After searching, for example, Chinese patent documents disclose a connection assembly for an all-terrain vehicle [Application No.: 202410957026.9; Publication No.: CN118499331A]. A connection assembly for an all-terrain vehicle, the all-terrain vehicle includes a first cover and a second cover; the connection assembly includes a base and a locking column, the locking column can be inserted into the base, and after the locking column is inserted into the base, the connection state between the locking column and the base can be changed by rotating the locking column to a preset angle; the base includes a first connecting plate, a second connecting plate and a locking portion, a first accommodating space is formed between the first connecting plate and the second connecting plate, and when the connection assembly is in a locked state, the first cover is at least partially located in the first accommodating space; the locking column includes a mounting column, an operating portion and a limiting portion, a second accommodating space is formed between the operating portion and the first connecting plate, and the first cover is at least partially located in the second accommodating space; the limiting portion abuts against a side of the locking portion away from the second connecting plate. This arrangement can quickly realize the disassembly and assembly of the relevant body covering parts, and improve the maintenance efficiency of the all-terrain vehicle.

[0004] Although this patent can quickly realize the disassembly and assembly of related body covering parts and improve the maintenance efficiency of all-terrain vehicles, due to the complex environment of harsh terrain, the all-terrain vehicle suffers greater damage to the suspension connection structure during driving, causing the ball head structure as the "joint" to be easily damaged, so it needs to be replaced frequently. However, the ball head structure is connected by integral stamping of the machine tool, which makes it difficult to disassemble when it needs to be disassembled. In addition, during the stamping process of the machine tool, the ball head seat is very likely to produce local deformation under the action of the stamping pressure, and in severe cases, it may also cause damage to the ball head seat, which not only increases the scrap rate of the ball head assembly, but also increases its production cost. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a connection assembly for an all-terrain vehicle.

[0007] The working principle of the present invention is: the stabilizing cover and the mounting seat can be fixedly connected by a fixing component, so that when the wheel frame is disassembled, the connection state between the stabilizing cover and the mounting seat can be cancelled by the fixing component, so that the ball head body is exposed, and then the ball head body is evenly divided into a split ball head 1 and a split ball head 2 by a combined component, and the split ball head 2 is taken out from the stabilizing cover, so that only the split ball head 1 is left in the stabilizing cover. At this time, since the ball head body has half of its structure missing, it can be taken out of the ball head slot more conveniently and quickly, thereby improving the disassembly and assembly efficiency between the wheel frame and the stabilizing arm, and then the rotational connection state between the stabilizing arm and the frame is ensured by controlling the rotating component, and the rotating component can realize convenient disassembly and assembly between the stabilizing arm and the frame, thereby improving the overall disassembly and assembly efficiency.

[0013] With the above structure, the combination fixing state between the combination block and the corresponding combination groove can be achieved by disassembling and installing the limit screw, and the fixed connection state between the split ball head 1 and the split ball head 2 can be further achieved.

[0014] A plurality of guide slots are provided in each of the combination blocks, each of which is slidably connected with a docking block, and a plurality of docking slots are provided in each of the combination slots, each docking block is docked with the corresponding docking slot, and a push spring is fixed between each docking block and the bottom of the corresponding guide slot, and one end of each docking block is beveled, and the inclined surface of each docking block is pushed and matched with the corresponding limit screw.

[0015] By adopting the above structure, each docking block can be continuously pushed during the insertion process of the limit screw, so that each docking block can complete the docking cooperation with the corresponding docking groove, further improving the fixed connection state between the split ball head 1 and the split ball head 2.

[0016] A pair of rotating wheels are rotatably connected in the other end of each docking block, and an anti-skid rubber layer is fixed on the wheel surface of each rotating wheel, and the wheel surface of each pair of rotating wheels is fitted with the groove wall of the corresponding docking groove, and a transmission bevel gear five is coaxially fixedly connected to each pair of rotating wheels, and a pair of transmission bevel gear six is ​​rotatably connected in each docking block, and each transmission bevel gear six is ​​meshed with the corresponding transmission bevel gear five, and a bidirectional lead screw is coaxially fixed between each pair of transmission bevel gears six, and the threaded sections on both sides of each bidirectional lead screw are threadedly connected with limiting blocks, and a pair of limiting slide grooves are opened on each docking groove, one end of each pair of limiting slide grooves is relatively inclined, and each limiting block is slidably connected to the corresponding limiting slide groove.

[0017] By adopting the above structure, during the process of docking the corresponding docking grooves through the docking block, the two rotating wheels contact the groove wall of the docking groove, and the rotation of the two rotating wheels is realized through the fit between the two. After the two rotating wheels rotate, the corresponding transmission bevel gear five will be driven to rotate, and after the transmission bevel gear five is rotated, the corresponding transmission bevel gear six will be driven to rotate, and after the transmission bevel gear six is ​​rotated, the two-way lead screw will be driven to rotate, and after the two-way lead screw is rotated, the corresponding limiting block will be driven to move, thereby completing the sliding connection with the corresponding limiting slide groove, and due to the inclination of the limiting slide groove, under normal circumstances, when the limiting block is not actively driven to move, it will interfere with and limit the limiting slide groove, further improving the connection strength between the split ball head one and the split ball head two, and improving the service life and effect.

[0018] A pair of shaft rods are inserted into the left and right sides of the frame, and each pair of shaft rods passes through the rotation point of the corresponding stabilizing arm. Both ends of each shaft rod are threadedly connected to a limiting nut, and each limiting nut is fixedly connected to the frame by bolts. A limiting annular groove is provided on each shaft rod, and a plurality of limiting sliders are arranged in the frame, and each limiting slider is slidably matched with the limiting annular groove.

[0019] By adopting the above structure, the shaft rod can be fixed by two limit nuts, and the shaft rod can be used as the rotation connection point between the stabilizing arm and the frame. Then, through the sliding cooperation between the limit slider and the limit annular groove, the stability of the rotation movement of the stabilizing arm can be corrected and maintained, thereby improving the running smoothness and structural strength.

[0021] By adopting the above structure, the operation block can be pushed to move, and the operation block further drives the rack to move synchronously. After the rack moves, it will mesh with the transmission gear to drive the transmission gear to rotate. After the transmission gear rotates, it will drive the push screw to rotate. After the push screw rotates, it will drive the corresponding limit slider to move, so that the limit slider can freely break away from the sliding connection state with the limit annular groove, which is convenient for disassembly of the shaft rod, and the limit annular groove can also be squeezed to simply fix the shaft rod, which is convenient for threaded connection between the shaft rod and the limit screw, thereby improving the overall disassembly speed.

[0022] A pair of stable slide grooves are provided on the left and right sides of each operating slide groove, a stable slider is slidably connected in each stable slide groove, a return spring is fixed between each stable slider and the bottom of the corresponding stable slide groove, a pair of connecting grooves are provided on the left and right sides of each rack, and one end of each stable slider is plugged into the corresponding connecting groove.

[0023] By adopting the above structure, the stable slider can be plugged into the corresponding connecting groove to achieve the sliding movement of the stable slider being restricted without the direct influence of external force, thereby improving the operation stability.

[0024] A split opening is provided in each of the tensioning cylinders, and the outer aperture of the screw hole in each tensioning cylinder is smaller than the inner aperture of the screw hole, a plurality of control slide grooves are provided in each plug-in cylinder, a control rack is slidably connected in each control slide groove, and a plurality of meshing gears are rotatably connected in each control tooth groove, and each meshing gear meshes with the corresponding control rack, a pushing plate is fixed to the bottom end of each control rack, and the bottom surface of each pushing plate contacts the outer wall of the corresponding tensioning cylinder, and a plurality of mounting blocks are slidably connected in each tensioning cylinder, and a plurality of mounting grooves are provided in each plug-in groove, and each mounting block is plugged into and matched with the corresponding mounting groove, and a bidirectional screw rod 2 is coaxially fixed on each meshing gear, and the threaded sections on both sides of each bidirectional screw rod 2 are threadedly connected to the corresponding mounting block, and a control spring is fixed between the top end of each control rack and the groove wall of the corresponding control slide groove.

[0025] By adopting the above structure, when the fixing bolt 1 is connected to the tensioning cylinder, since the outer diameter of the screw hole in the tensioning cylinder is smaller than the inner diameter of the screw hole, the structure on the outer side of the tensioning cylinder will expand and deform. In order to ensure stable operation in the deformed state, the tensioning cylinder can be made of plastic or other materials that can be bent and deformed after molding, and then the pushing plate is pushed by the expansion deformation of the structure on the outer side of the tensioning cylinder, so that the pushing plate further pushes the control rack to lift. During the lifting process of the control rack, multiple meshing gears will be driven to rotate. After the rotation of the multiple meshing gears, the corresponding two-way screw rods 2 will be driven to rotate. The two-way screw rods 2 will then drive the corresponding mounting blocks to move in relative or opposite directions. At this time, the plug-in fit between the mounting block and the corresponding mounting groove is completed, further improving the installation fixity of the stable cover and improving the strength of the connection structure.

[0026] Compared with the prior art, the connection assembly for an all-terrain vehicle has the following advantages: 1. The stabilizing cover and the mounting seat are fixedly connected by a fixing assembly. When the wheel frame is disassembled, the connection state between the stabilizing cover and the mounting seat can be cancelled by the fixing assembly, so that the ball head body is exposed, and then the ball head body is evenly divided into split ball head 1 and split ball head 2 by the combined assembly, and the split ball head 2 is taken out from the stabilizing cover, so that only the split ball head 1 is left in the stabilizing cover. At this time, since the ball head body is half of the structure, it can be taken out of the ball head slot more conveniently and quickly, thereby improving the disassembly and assembly efficiency between the wheel frame and the stabilizing arm, and no stamping equipment is required to perform stamping connection between the ball head and the ball head seat.

[0027] 2. By splitting the multiple linkage limit structures between the ball head 1 and the ball head 2, the strength of the connection structure between the two is further improved without affecting the ability of the two to be quickly disassembled and assembled, thereby improving the service life and use effect.

[0028] 3. Through the sliding cooperation between the limit slider and the limit annular slide groove, the stability of the rotation of the stabilizing arm is corrected and maintained to improve the running smoothness and structural strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] A pair of stable slide grooves 45 are provided on the left and right sides of each operating slide groove 42, and a stable slider 46 is slidably connected in each stable slide groove 45. A return spring 30 is fixed between each stable slider 46 and the bottom of the corresponding stable slide groove 45. A pair of connecting grooves 47 are provided on the left and right sides of each rack 43, and one end of each stable slider 46 is plugged into the corresponding connecting groove 47.

[0059] With the above structure, the stabilizing slider 46 can be plugged into the corresponding connecting groove 47 to restrict the sliding movement of the stabilizing slider 46 without the direct influence of external force, thereby improving the operational stability.

[0060] Each of the tensioning tubes 48 is provided with a split opening 49, and the outer diameter of the screw hole in each tensioning tube 48 is smaller than the inner diameter of the screw hole. Each of the plug-in tubes 9 is provided with a plurality of control slide grooves 50, each of which is slidably connected with a control rack 51, and each of the control tooth grooves is rotatably connected with a plurality of meshing gears 52, each of which is meshed with a corresponding control rack 51, and a push plate 53 is fixed to the bottom end of each control rack 51, and the bottom surface of each push plate 53 is in contact with the corresponding tensioning The outer wall of the cylinder 48 is in contact with each other, and a plurality of mounting blocks 54 are slidably connected in each tensioning cylinder 48, and a plurality of mounting grooves 55 are opened in each plug-in groove 10, each mounting block 54 is plugged into and matched with the corresponding mounting groove 55, and a bidirectional screw rod 2 56 is coaxially fixed on each meshing gear 52, and the threaded sections on both sides of each bidirectional screw rod 2 56 are threadedly connected with the corresponding mounting block 54, and a control spring 57 is fixed between the top of each control rack 51 and the groove wall of the corresponding control slide groove 50.

[0061] By adopting the above structure, when the fixing bolt 13 is connected to the tensioning tube 48, since the outer diameter of the screw hole in the tensioning tube 48 is smaller than the inner diameter of the screw hole, the structure outside the tensioning tube 48 will expand and deform. In order to ensure stable operation in the deformed state, the tensioning tube 48 can be made of a material such as plastic that can be bent and deformed after molding, and then the expansion deformation of the structure outside the tensioning tube 48 pushes the pushing plate 53, so that the pushing plate 53 further pushes the control rack 51 to lift. During the lifting process of the control rack 51, the multiple meshing gears 52 will be driven to rotate. After the multiple meshing gears 52 rotate, the corresponding two-way screw rods 56 will be driven to rotate. The two-way screw rods 56 then drive the corresponding mounting block 54 to move in the opposite direction or opposite direction. At this time, the plug-in cooperation between the mounting block 54 and the corresponding mounting groove 55 is completed, further improving the installation fixity of the stable cover 5 and improving the strength of the connection structure.

[0062] The working principle of the present invention is as follows: the shaft rod 36 is fixed by two limit nuts 37, and the shaft rod 36 is used as the rotation connection point between the stabilizing arm 2 and the frame 1, and then the sliding cooperation between the limit slider 39 and the limit annular slide groove 38 is used to correct and maintain the stability of the rotation action of the stabilizing arm 2, thereby improving the running smoothness and structural strength. The operation block 44 is pushed to move, and the operation block 44 further drives the rack 43 to move synchronously. After the rack 43 moves, it will mesh with the transmission gear 41 to drive the transmission gear 41 to rotate. After the transmission gear 41 rotates, it will drive the push screw 40 to rotate. After the push screw 40 rotates, it will drive the corresponding limit slider 39 to move, so that the limit slider 3 9 can be freely separated from the sliding connection state with the limiting annular groove 38, which is convenient for disassembling the shaft rod 36, and the limiting annular groove 38 can also be squeezed to simply fix the shaft rod 36, which is convenient for threading the shaft rod 36 and the limiting screw 24, thereby improving the overall disassembly speed. After the stabilizing arm 2 is installed, the split ball head 1 7 can be inserted into the stabilizing cover 5, and then the split ball head 2 8 can be combined on the split ball head 1 7. At this time, the combined fixed state between the combination block 22 and the corresponding combination groove 23 is realized through the disassembly and installation of the limiting screw 24, and the fixed connection state between the split ball head 1 7 and the split ball head 2 8 is further realized. The limiting screw 24 is inserted during the continuous pushing of each docking block 26, so that each docking The block 26 can complete the docking cooperation with the corresponding docking groove 27, further improving the fixed connection state between the split ball head 1 7 and the split ball head 2 8. In the process of docking the corresponding docking groove 27 by the docking block 26, the two rotating wheels 29 contact the groove wall of the docking groove 27, and the two rotating wheels 29 are rotated through the fit between the two. After the two rotating wheels 29 rotate, they will drive the corresponding transmission bevel gear 5 31 to rotate. After the transmission bevel gear 5 31 rotates, it will drive the corresponding transmission bevel gear 6 32 to rotate. After the transmission bevel gear 6 32 rotates, it will drive the two-way lead screw 33 to rotate. After the two-way lead screw 33 rotates, it will drive the corresponding limiting block 34 to move, thereby completing the sliding with the corresponding limit sliding groove. The limiting block 34 is dynamically connected, and due to the inclination of the limiting slide groove 35, under normal circumstances, when the limiting block 34 is not actively driven to move, it will interfere with and limit the limiting slide groove 35, and form a multiple linkage limit structure with the above structure, further improving the connection strength between the split ball head 7 and the split ball head 8, and improving the service life and effect. Through the plug-in cooperation between the plug-in tube 9 and the plug-in groove 10, the rapid pre-fixation between the stable cover 5 and the mounting seat 4 is realized, and then the hexagonal nut 21 is driven to rotate by the hexagonal wrench. After the hexagonal nut 21 rotates, the worm 20 is driven to rotate. After the worm 20 rotates, the worm wheel 19 is driven to rotate. After the worm wheel 19 rotates, the transmission bevel gear 4 18 is driven to rotate.When the transmission bevel gear 4 18 rotates, it will drive the transmission bevel gear 3 17 to rotate. When the transmission bevel gear 3 17 rotates, it will drive the transmission bevel gear 2 15 to rotate. When the transmission bevel gear 2 15 rotates, it will drive the transmission bevel gear 1 14 to rotate. When the transmission bevel gear 1 14 rotates, it will drive the two-way screw 1 16 to rotate. The two-way screw 1 16 further drives the two limit arms 12 to move in the opposite or opposite directions, thereby realizing the plug-in cooperation between the limit arms 12 and the corresponding plug-in tubes 9, thereby further limiting the fixed state of the stabilizing cover 5 and the mounting seat 4, and completing the connection between the stabilizing arm 2 and the frame 1 and the wheel frame 3.

[0063] In summary, the stabilizing cover 5 and the mounting seat 4 are fixedly connected by the fixing assembly, so that when the wheel frame 3 is disassembled, the connection state between the stabilizing cover 5 and the mounting seat 4 can be cancelled by the fixing assembly, so that the ball head body is exposed, and then the ball head body is evenly divided into a split ball head 1 7 and a split ball head 2 8 by the combined assembly, and the split ball head 2 8 is taken out of the stabilizing cover 5, so that only the split ball head 1 7 is left in the stabilizing cover 5. At this time, since the ball head body has half of its structure missing, it can be taken out of the ball head slot 6 more conveniently and quickly, thereby improving the disassembly and assembly efficiency between the wheel frame 3 and the stabilizing arm 2, and then the rotational connection state between the stabilizing arm 2 and the frame 1 is ensured by the control of the rotating assembly, and the rotating assembly can facilitate the disassembly and assembly between the stabilizing arm 2 and the frame 1, thereby improving the overall disassembly and assembly efficiency.
