Description

Technical Field

[0001] This utility model relates to the field of all-terrain vehicle canopy technology, and in particular to a detachable structure for an all-terrain vehicle canopy. Background Technology

[0002] In the traditional manufacturing process of all-terrain vehicle canopies, a one-piece welding technique is commonly used to permanently connect the supporting structure to the vehicle frame. This process, through continuous welds, integrates the canopy frame with the vehicle frame, effectively ensuring the integrity and load-bearing strength of the structure. However, this permanent connection method also brings significant limitations: when vehicles need to be transported or stored, the canopy cannot be disassembled, greatly increasing space occupation; during routine maintenance, individual replacement of parts is not possible; more importantly, this rigid connection method is prone to fatigue cracks at the welds due to stress concentration when driving on complex terrain.

[0003] In recent years, an improved connection method has emerged, employing a combination of plug-in fittings and bolt fastening. This solution designs the carport support rods as a segmented structure, using plug-in connectors and sleeves at the joints for rapid alignment and assembly, further secured with transverse bolts. This design allows the main support components to be disassembled into multiple units, enabling disassembly for transportation or storage, effectively reducing space requirements while maintaining sufficient connection strength. The fitting clearances at the plug-in joints are carefully designed to ensure both smooth assembly and stability after connection.

[0004] However, this plug-in structure still has significant drawbacks: although the main support rod is detachable, the basic anchor points connecting to the frame are still fixed to the frame using traditional welding methods. These anchor points, as the load-bearing foundation of the entire canopy structure, are highly susceptible to damage from collisions or excessive loads in the harsh operating environment of all-terrain vehicles. Once the anchor points deform or their threads are damaged, repair and replacement are extremely difficult because they are directly welded to the frame—the original weld points must be removed using cutting tools, and new anchors must be re-welded after surface treatment. This repair method is not only complex and time-consuming, but more importantly, it causes secondary damage to the frame itself, reducing its structural integrity. Furthermore, welding operations require specialized equipment and technicians, making on-site repairs virtually impossible in field conditions, significantly impacting the vehicle's usability. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable structure for an all-terrain vehicle canopy, which solves the technical problem that in the prior art, the canopy foundation anchor points are fixed to the vehicle frame by welding, which makes repair and replacement difficult after damage, requires professional welding equipment and technicians to operate, and the repair process will cause secondary damage to the vehicle frame.

[0006] To achieve the above objectives, this utility model provides a detachable structure for an all-terrain vehicle canopy, comprising four threaded rods, each of which is connected to an external vehicle frame via threads. A limiting plate is fixedly installed at the top of each threaded rod, and the limiting plate has symmetrically formed fixing holes on its edge. Bolts pass through the fixing holes and are threadedly connected to the external vehicle frame to form a fixed connection. A plug is fixedly installed in the middle of the top of the limiting plate, and the plug is inserted into the bottom of the front support frame and the rear support frame respectively and fixed with bolts.

[0007] The front support frame and the rear support frame are each two in number. A first support crossbar is fixedly installed between the front support frames, and a second support crossbar is fixedly installed between the rear support frames.

[0008] The front support frame and the rear support frame are respectively connected and fixed with bolts, and the two ends of the two support rods are respectively fixedly installed with the bolts.

[0009] Upper clamps are respectively fitted on the outer side of the front support frame adjacent to the first support crossbar, the outer side of the rear support frame adjacent to the second support crossbar, and the outer side of the support longitudinal bar.

[0010] The upper clamp is fitted with a lower clamp via a pin at its bottom, and clamps are fixedly installed at the openings of the upper and lower clamps, with the clamps being fixed together by bolts.

[0011] The upper clamps are installed at intervals on both sides of the bottom end of the shelf, and the top of the shelf is equipped with reinforcing ribs at intervals along the width direction, with the reinforcing ribs extending obliquely from the middle to both ends.

[0012] This utility model discloses a detachable structure for an all-terrain vehicle canopy. Initial fixation is achieved through a threaded rod connected to pre-drilled threaded holes in the external frame. A limiting plate is located at the top of the threaded rod, and fixing holes on the edge of the limiting plate allow for additional connection to the frame via bolts. This dual-fixing method ensures a secure connection while effectively preventing the threaded rod from loosening during use. A vertically positioned insert at the top of the limiting plate engages with the sleeve structure at the bottom of the front and rear support frames, achieving quick positioning through an insertion method. This is further secured with transverse bolts, forming a detachable rigid connection between the entire support frame and the foundation anchor point. This connection method eliminates the need for welding between the canopy's foundation anchor point and the frame; instead, standardized threaded connections allow for easy replacement. When an anchor point requires repair due to collision or damage, the damaged part can be replaced simply by loosening the relevant bolts, eliminating the need for cutting and preventing secondary damage to the frame. This significantly improves maintenance convenience and operational feasibility. Attached Figure Description

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-5 .

[0022] This utility model provides a detachable structure for an all-terrain vehicle canopy, comprising four threaded rods 101. These threaded rods 101 are initially fixed by being screwed into pre-drilled threaded holes on the external frame. A limiting plate 102 is welded to the top of each threaded rod 101. The limiting plate 102 has symmetrically machined fixing holes 103 along its edges. Bolts are passed through the fixing holes 103 to further connect the rod to the frame, forming a double safety measure to prevent the threaded rods 101 from rotating. A plug rod 104 is vertically welded to the center of the top of the limiting plate 102. The outer diameter of the plug rod 104 matches the inner diameter of the sleeves at the bottom of the front support frame 105 and the rear support frame 106, achieving precise insertion. A transverse bolt is then used for through-and-through fixing, ensuring a reliable connection between the support frame and the base components.

[0023] The two front support frames 105 are welded together as a whole by a first support crossbar 107, and the two rear support frames 106 are welded together as a whole by a second support crossbar 108, forming two stable portal-shaped support frames at the front and rear. Mounting holes are opened at corresponding positions on the upper part of the front support frame 105 and the rear support frame 106. Inserted posts 109 are inserted into these holes and secured with bolts. The two ends of the inserted posts 109 are welded and fixed to the ends of the two support longitudinal bars 110, thereby connecting the front and rear frames into a single unit, forming a complete three-dimensional load-bearing skeleton.

[0024] On the assembled frame, upper clamps 111 are installed at predetermined positions: the front support 105 adjacent to the first support crossbar 107, the rear support 106 adjacent to the second support crossbar 108, and the two support longitudinal bars 110. The bottom of the upper clamp 111 is hinged to the lower clamp 112 via a pin 113, forming an openable and closable annular clamping structure. Clamping plates 114 are welded to the open ends of the upper clamp 111 and the lower clamp 112. The clamping plates 114 have through holes, and after being tightened with bolts and nuts, the clamps tightly fit onto the frame members.

[0025] The canopy panel 115 is installed on top of the frame, and the bottom two sides of the canopy panel 115 are fixedly connected to the top of the upper clamp 111 at the corresponding clamp positions. When the clamps are tightened, the canopy panel 115 is firmly installed on the frame. A reinforcing rib 116 is welded to the top of the canopy panel 115 along the width direction. The reinforcing rib 116 is arranged in a radial pattern extending diagonally from the middle to both ends, which can effectively improve the bending stiffness and deformation resistance of the canopy panel 115.

[0026] This embodiment achieves modular assembly and disassembly of the canopy structure through various methods such as threaded connections, plug-in fittings, and clamping. The components work together to form a stable spatial structural system, ensuring both overall rigidity and strength while meeting the practical needs of all-terrain vehicles for detachable structures.

[0027] Working principle: Four threaded rods 101 are initially connected to the external frame through threads, forming the foundation of the entire canopy system; to ensure the reliability of the connection, the limiting plate 102 at the top of the threaded rod 101 is fastened to the frame for a second time by bolts through the fixing holes 103 symmetrically opened on its edge. This double fixing design effectively prevents the thread from backing out due to vibration during vehicle operation, providing a stable support foundation for the upper structure.

[0028] After the basic installation is completed, the insertion rod 104 at the top of the limiting plate 102 is inserted into the sleeve at the bottom of the front support frame 105 and the rear support frame 106 respectively, and locked laterally by bolts. This connection method of insertion and bolt fastening not only ensures quick alignment during installation, but also achieves rigid fixation of the connection node. The front and rear support frames 106 are connected into two stable portal frames by the first support crossbar 107 and the second support crossbar 108 respectively, which significantly enhances the lateral rigidity of the structure.

[0029] The connection between the front and rear canopies is achieved through insert posts 109. Insert posts 109 are inserted into the pre-set mounting holes on the front and rear supports 106 and fastened with bolts. Insert posts 109 themselves are fixedly connected to the ends of the two support longitudinal rods 110. In this way, through the bridging effect of insert posts 109, the two independent canopies are connected into a complete three-dimensional spatial structure. The support longitudinal rods 110 not only enhance longitudinal stability, but also provide intermediate support points for the installation of the upper canopy panel 115.

[0030] The shelf panel 115 is fixed by a series of clamp components. Under the synergistic action of the upper clamp 111 and the lower clamp 112, the shelf panel 115 is firmly clamped to the shelf structure. Specifically, the upper clamp 111 is arranged on both sides of the bottom end of the shelf panel 115, and the lower clamp 112 is hinged to the upper clamp 111 through the pin 113, so that the clamp can be opened and closed. When the shelf panel 115 is in place, the upper and lower clamps 112 close, and the clamping plate 114 welded at its opening is fastened by bolts, generating a strong clamping force, so that the shelf panel 115 and the lower shelf form an integral whole. It is particularly noteworthy that the installation position of the clamps is carefully designed and located at the key nodes of the front support frame 105 and the first support crossbar 107, the rear support frame 106 and the second support crossbar 108, and the support longitudinal bar 110. This layout not only enhances the connection strength, but also improves the energy transfer efficiency, so that the entire structure can better disperse stress when subjected to impact.

[0031] To enhance the rigidity of the canopy panel 115, multiple reinforcing ribs 116 are provided at its top along the width direction. These reinforcing ribs 116 are arranged in a radial pattern extending diagonally from the middle to both ends. This radial layout can effectively spread the concentrated load to all sides, significantly improving the canopy panel 115's resistance to bending and deformation, and ensuring that the carport can maintain its shape integrity even under harsh road conditions.

[0032] The entire system achieves modular design through multiple bolted connections and plug-in joints; the coordinated work between the components forms a stable spatial force system: the threaded rod 101 provides vertical support, the front and rear canopy structures form the main load-bearing frame, the support longitudinal rod 110 ensures longitudinal stability, the clamp system achieves a combination of flexible and rigid connections, and the reinforcing rib 116 enhances the structural strength of the cover; this design enables the canopy to ensure structural robustness and safety while also having good disassembly, facilitating transportation, storage and maintenance, and perfectly adapting to the diverse usage needs of all-terrain vehicles.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
