Description

Technical Field

[0001] This utility model relates to the field of amusement vehicle technology, and more specifically, to an amphibious vehicle. Background Technology

[0002] Amphibious vehicles are recreational vehicles used for driving on beaches and water surfaces. Currently, Chinese Patent Publication No. CN211969098U discloses a wheel drive mounting structure for an amphibious vehicle. When this amphibious vehicle is driven on the water, the entire vehicle is suspended on the water surface solely by the buoyancy of its four wheels. This results in poor levitation ability of the amphibious vehicle on the water surface. Furthermore, the four wheels are responsible for both levitation and driving the amphibious vehicle's movement and steering, which can easily lead to the amphibious vehicle overturning. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an amphibious vehicle that, through the setting of a float, enables the amphibious vehicle to reliably suspend on the water surface. This improves the stability of the amphibious vehicle when the walking mechanism drives the amphibious vehicle to move and turn on the water surface, effectively avoids the amphibious vehicle from overturning, and improves the safety of the amphibious vehicle when driving on the water surface.

[0004] This utility model provides an amphibious vehicle, including a frame; two walking mechanisms are connected to the left and right sides of the frame, which are distributed in a front-to-back interval, and each walking mechanism includes a drive component and a wheel; the drive component is fixed on the frame, and the wheel is drivenly connected to the output shaft of the drive component; the amphibious vehicle also includes a float; the frame is fixed to the upper end of the float, and the lower end surface of the float is higher than the lower edge of the wheel; when the float floats on the water surface, the lower edge of the wheel is submerged in the water.

[0005] By incorporating a float, this invention effectively suspends the amphibious vehicle on the water surface, ensuring its reliable levitation. This enhances the vehicle's stability when the walking mechanism propels it forward and turns, preventing rollover and improving overall safety.

[0006] In one possible implementation, the frame is secured to the float by a plurality of fastening components arranged circumferentially at intervals; each fastening component includes a bolt and a nut; the outer wall of the float is provided with a groove corresponding to each fastening component, and the threaded portion of each bolt extends vertically through the bottom edge of the frame and the float above the groove and then into the groove, and the nut is threadedly connected to the threaded portion of the bolt, and the nut abuts against the top of the groove; by adopting this structure, with the threaded portion of the bolt extending vertically through the bottom edge of the frame and the float above the groove and into the groove, and after the nut and the threaded portion of the bolt are threadedly tightened, the frame can be reliably fixed to the upper end of the float.

[0007] In one possible implementation, each groove is embedded with a stop block that fits tightly into the groove. The stop block is used to cover the nut. By setting the stop block, the stop block can cover the nut and the bolt thread in the groove, so that the nut and bolt thread cannot be seen from the outside of the buoy. This can improve the appearance of the amphibious vehicle. In addition, since the stop block fits tightly into the groove, it has the advantage of easy fastening of the stop block and the groove.

[0008] In one possible implementation, the stop block tapers inward to form a wedge-shaped structure, and the shape of the groove matches the shape of the stop block. By using a stop block of this shape, the stop block can be more easily embedded into the groove when the stop block and the groove are fitted together, which facilitates the fitting of the stop block and the groove.

[0009] In one possible implementation, an opening groove is provided on the inner end of the stop block, which is used for the threaded portion of the nut and bolt to slide horizontally into. By providing an opening groove on the inner end of the stop block, the opening groove allows the threaded portion of the nut and bolt to slide horizontally into, thereby enabling the stop block to be inserted into the groove to the maximum extent, that is, increasing the depth of the stop block inserted into the groove, so that the stop block is reliably fitted into the groove.

[0010] In one possible implementation, an outwardly expanding step is provided at the upper end of the opening groove, and an arc-shaped expansion portion is formed at the outer end of the step. A washer is sleeved on the outside of the bolt's threaded portion. The washer is pressed against the inner top of the groove by the nut, and the washer is inserted into the expansion portion through the opening at the inner end of the step. With this structure, the loosening between the nut and the bolt can be effectively prevented under the action of the washer. Furthermore, during the process of the stop block being embedded in the groove, the washer can be inserted into the expansion portion through the opening at the inner end of the step, that is, the stop block can cooperate and be clamped with the washer, thereby further fixing the stop block and further preventing the stop block from coming out of the groove.

[0011] In one possible implementation, pedal assemblies are fixed to both sides of the frame; each pedal assembly includes two side plates and two crossbeams; the two side plates of each pedal assembly are symmetrically fixed to one side of the frame, and the two crossbeams of each pedal assembly are spaced apart from the inside to the outside between the two side plates on the corresponding side; notches corresponding to the pedal assemblies are provided on the outer walls of both sides of the buoy; the lower edges of the two side plates of each pedal assembly are engaged with one of the slots located at the bottom of the corresponding notch; and the two crossbeams of each pedal assembly are engaged with one of the grooves located at the bottom of the corresponding notch; by adopting this structure, the notches can avoid the pedal assemblies, and when the user gets on and off the amphibious vehicle, the user can step on the crossbeams of the pedal assembly to avoid the buoy being damaged by being stepped on.

[0012] In one possible implementation, the float is formed by splicing two symmetrically arranged semi-sections together. The frame is fixed to the upper end of the two semi-sections. The notch, two slots, and two grooves on each side of the frame are symmetrically formed on the two semi-sections. By using two symmetrically arranged semi-sections to form the float, only two identical semi-sections need to be produced to form the float, thus effectively reducing the production difficulty of the float. Furthermore, since the two slots are symmetrically formed on the two semi-sections, after the lower edge of the side plate is inserted into the slot, it can provide a front-to-back tension to the two semi-sections, thereby improving the fixation firmness of the two semi-sections.

[0013] In one possible implementation, the upper ends of the two side plates in each pedal assembly are fastened to the frame by bolt assemblies; with this structure, each side plate can be reliably fastened to the frame.

[0014] In one possible implementation, both ends of each crossbeam are inserted into two side plates in the corresponding pedal assembly and welded to the side plates for fixation. With this structure, each crossbeam can be reliably fastened to the side plates, and since both ends of each crossbeam are inserted into two side plates in the corresponding pedal assembly, it has the advantages of good support effect of the side plates for the crossbeam and high reliability.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figure 1-5 As shown in the embodiment of this application, an amphibious vehicle is disclosed, including a frame 1. Two walking mechanisms are connected to the left and right sides of the frame 1, which are distributed in a front-to-back interval. Each walking mechanism includes a drive component 21 and a wheel 22. The drive component 21 is fixed on the frame 1, and the wheel 22 is drivenly connected to the output shaft of the drive component 21. The amphibious vehicle also includes a float 3. The frame 1 is fixed to the upper end of the float 3, and the lower end surface of the float 3 is higher than the lower edge of the wheel 22. When the float 3 floats on the water surface, the lower edge of the wheel 22 is submerged in the water. The above-mentioned walking mechanism is the prior art of amphibious vehicles currently on the market. For example, the walking mechanism consisting of a motor, a transmission and wheels in the wheel drive mounting structure of an amphibious vehicle disclosed in Chinese Patent Publication No. CN211969098U is not described in detail here.

[0025] The frame 1 is fixed to the float 3 by a number of fastening components distributed circumferentially. Each fastening component includes a bolt 41 and a nut 42. The outer wall of the float 3 is provided with a groove 31 corresponding to each fastening component. The threaded part of each bolt 41 extends vertically through the bottom edge of the frame 1 and the float 3 above the groove 31 and then into the groove 31. The nut 42 is threadedly connected to the threaded part of the bolt 41 and abuts tightly against the top of the groove 31. With this structure, the frame can be reliably fixed to the upper end of the float after the threaded part of the bolt extends vertically through the bottom edge of the frame and the float above the groove and into the groove, and after the nut and the threaded part of the bolt are threadedly fastened.

[0026] Each groove 31 is embedded with a stop block 5, which fits tightly with the groove 31. The stop block 5 is used to cover the nut 42. By setting the stop block, the stop block can cover the nut and the bolt thread in the groove, so that the nut and bolt thread cannot be seen from the outside of the float, thereby improving the appearance of the amphibious vehicle. In addition, since the stop block fits tightly with the groove, it has the advantage of easy fastening of the stop block and the groove.

[0027] The stop block 5 is formed into a wedge shape by contracting from the outside to the inside, and the shape of the groove 31 is adapted to the shape of the stop block. By using this shape of stop block, the stop block can be more easily embedded into the groove when the stop block and the groove are fitted together, which can facilitate the fitting of the stop block and the groove.

[0028] An opening groove 51 is provided on the inner end of the stop block 5. The opening groove 51 is used for the nut 42 and the threaded part of the bolt 41 to slide horizontally into it. After the opening groove is provided on the inner end of the stop block, the opening groove can allow the nut and the threaded part of the bolt to slide horizontally into it, thereby enabling the stop block to be inserted into the groove to the maximum extent, that is, to increase the depth of the stop block inserted into the groove, so that the stop block can be reliably fitted into the groove.

[0029] An outwardly expanding step 52 is provided at the upper end of the opening groove 51. An arc-shaped expansion portion 521 is formed at the outer end of the step 52. A washer 43 is sleeved on the outside of the threaded portion of the bolt 41. The washer 43 is pressed against the inner top of the groove 31 by the nut 42. The washer 43 is inserted into the expansion portion 521 through the opening at the inner end of the step 52. With this structure, the loosening between the nut and the bolt can be effectively prevented under the action of the washer. In addition, during the process of the stop block being embedded in the groove, the washer can be inserted into the expansion portion through the opening at the inner end of the step, that is, the stop block can cooperate with the washer to lock it, thereby further fixing the stop block and further preventing the stop block from coming out of the groove.

[0030] Both sides of the frame 1 are fixed with pedal assemblies 6; each pedal assembly 6 includes two side plates 61 and two crossbeams 62; the two side plates 61 in each pedal assembly 6 are fixed symmetrically to one side of the frame 1, and the two crossbeams 62 in each pedal assembly 6 are spaced apart from the inside to the outside between the two side plates 61 on the corresponding side; notches 32 corresponding to the pedal assemblies 6 are provided on the outer walls of the left and right sides of the buoy 3; the lower edges of the two side plates 61 in each pedal assembly 6 are engaged with one of the slots 33 located at the bottom of the corresponding notch 32; the two crossbeams 62 in each pedal assembly 6 are engaged with one of the grooves 34 located at the bottom of the corresponding notch 32; by adopting this structure, the notches can avoid the pedal assemblies, and when the user gets on and off the amphibious vehicle, the user can step on the crossbeams of the pedal assembly to avoid the buoy being damaged by being stepped on.

[0031] The float 3 is formed by splicing two symmetrically arranged spliced ​​halves 35. The frame 1 is fixed to the upper end of the two spliced ​​halves 35. The notch 32, two slots 33 and two grooves 34 on each side of the frame 1 are symmetrically formed on the two spliced ​​halves 35. By using two symmetrically arranged spliced ​​halves to form the float, only two identical spliced ​​halves need to be produced to form the float, which can effectively reduce the production difficulty of the float. Since the two slots are symmetrically formed on the two spliced ​​halves, after the lower edge of the side plate is inserted into the slot, it can play a role in tightening the two spliced ​​halves from front to back, thereby improving the fixation firmness of the two spliced ​​halves.

[0032] The upper ends of the two side plates 61 in each pedal assembly 6 are fastened to the frame 1 by bolt assemblies; with this structure, each side plate can be reliably fastened to the frame.

[0033] Both ends of each crossbeam 62 are inserted into the two side plates 61 in the corresponding pedal assembly 6 and welded to the side plates 61 for fixation. With this structure, each crossbeam can be reliably fastened to the side plate, and since both ends of each crossbeam are inserted into the two side plates in the corresponding pedal assembly, it has the advantages of good support effect of the side plate for the crossbeam and high reliability.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
