Description

Technical Field

[0001] This invention belongs to the technical field of ground grid mechanisms, specifically a foldable ground grid mechanism for bumper car platforms. Background Technology

[0002] Bumper cars are a type of amusement ride. The equipment includes the bumper cars themselves and a flat track. Bumper cars are categorized into three types: ceiling-mounted bumper cars (with an electrified electric grid on the ceiling), floor-mounted bumper cars (using an electrified floor at designated points), and battery-powered bumper cars (with built-in batteries that run on a full charge). Professional amusement park bumper cars are typically made of fiberglass and generally seat a maximum of two people. They include pedals for acceleration and a steering wheel for steering.

[0003] However, during the installation of the folding ground net bumper car track, it is often necessary to manually lay the ground net, and one person cannot complete the relevant work. Therefore, a large amount of manpower is required to lay the ground net structure, which seriously wastes human and financial resources. Moreover, after the ground net is laid, the ground net frame is prone to instability and tilting.

[0004] Because the ground grid is heavy, folding it requires a lot of labor. Furthermore, after folding, the adjacent ground grid frames in the middle of the ground grid mechanism cannot fit together for a long time, which causes deformation in the middle of the ground grid mechanism. This renders the entire ground grid mechanism unusable, resulting in serious waste of resources. Therefore, a foldable ground grid mechanism for bumper car platforms is designed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable ground net mechanism for bumper car platforms, which solves the problems of the aforementioned ground net mechanism requiring a large amount of manpower to complete the laying, resulting in wasted manpower; the ground net frame being unstable and prone to tilting after being laid out; and the ground net frame being unable to fit together in the middle of the ground net mechanism for a long time, resulting in deformation in the middle of the ground net mechanism, making the entire ground net mechanism unusable and seriously wasting costs.

[0006] To address the aforementioned technical problems, this invention provides a foldable ground net mechanism for a bumper car platform. The ground net mechanism is installed on one or both sides of the bumper car platform, and a base frame is provided below the ground net mechanism. The ground net mechanism includes a follower section, a driven section, and an active section connected in sequence. All three sections are connected by a first connecting component. The follower section is connected to the bumper car platform through the first connecting component.

[0007] The driven section has two sets of supporting driven components at its bottom. One set of supporting driven components is located at the connection between the driven section and the driving section, and the other set of supporting driven components is connected to the driven section. The bottoms of the two sets of supporting driven components are connected by a connecting plate. The bottom of the driving section has several drive wheels. The drive wheels are connected to a drive mechanism. The drive mechanism drives the drive wheels to roll on the base frame, causing the driving section, driven section and follower section to be flattened or folded.

[0008] Furthermore, the first connecting assembly includes a first connecting shaft and two first bushings and a third bushing sleeved on the first connecting shaft. The second bushing sleeve is sleeved in the middle of the first connecting shaft. The two first bushings are respectively disposed on both sides of the second bushing sleeve, and the two third bushings are respectively disposed on both sides of the first bushing sleeve.

[0009] Furthermore, the active section includes a first ground grid frame and a second ground grid frame, the first ground grid frame and the second ground grid frame being fixedly connected to the outer sides of the first bushing and the second bushing, respectively;

[0010] The driven section includes a third ground grid frame and a fourth ground grid frame. The third ground grid frame and the second ground grid frame are respectively fixedly connected to the outer sides of the first bushing and the second bushing. The third ground grid frame and the fourth ground grid frame are respectively fixedly connected to the outer sides of the first bushing and the second bushing. A first support plate is fixed to the bottom of the second bushing of the first connecting assembly between the fourth ground grid frame and the driven section.

[0011] Furthermore, the bottom of the first ground grid frame is provided with a plurality of first hinge assemblies at intervals. Each first hinge assembly includes a linkage and a second support plate. The top of each second support plate is connected to the first ground grid frame through the linkage, and the bottom is equipped with the drive wheel.

[0012] Furthermore, each of the supporting driven components includes a first flip plate and two second flip plates, the first flip plate being connected to the two second flip plates respectively via a second hinge assembly, and a driven wheel being installed at the bottom of the first flip plate;

[0013] One set of first flip plates is fixed to the second bushing of the first connecting assembly between the second and third ground grid frames, while the other set of first flip plates is connected to the fourth ground grid frame via a third hinge assembly.

[0014] Furthermore, the two second flip plates of the two groups are connected by the connecting plate, and the bottom of the connecting plate is flush with the bottom of the base frame.

[0015] Furthermore, each of the three sections has a connector on both sides for hooking the chain.

[0016] Furthermore, the third hinge assembly includes a fixing frame and a third hinge connecting shaft. The fixing frame is fixedly installed inside the fourth ground frame, and its bottom is flush with the bottom of the fourth ground frame. Both ends of the third hinge connecting shaft are fitted with third hinge bushings. The top of the third hinge connecting shaft is fixedly connected to the bottom of the fixing frame. The bottoms of the two third hinge bushings are welded and fixed to the top of the first flip plate.

[0017] Furthermore, the first ground grid frame is connected to the top support of the bumper car platform via hook chains.

[0018] The beneficial effects of the present invention are as follows: The present invention provides several drive wheels at the bottom of the active section. The drive wheels are driven by a drive mechanism and roll on the base frame. A support driven component is installed on the ground grid frame. The driven wheel of the support driven component can rotate in the direction of rotation of the drive wheel, thereby effectively reducing labor consumption and labor costs, while also improving the deployment and take-up efficiency of the ground grid mechanism.

[0019] The design of the drive wheel and the supporting driven components effectively increases the service life of the ground grid mechanism, thereby solving the problem of the ground grid frame being damaged to a certain extent due to the long-term hard sliding on the base frame. At the same time, it solves the problem of the increased burden on the drive mechanism and hydraulic device when there is no support and guiding force from the drive wheel and the driven wheel.

[0020] The folding or support is driven by the first hinge assembly. The support driven assembly adjusts the rotation angle of the first flip plate through the third hinge assembly and the first connecting assembly. The two second flip plates adjust their angle with the first flip plate through the second hinge assembly. The connecting plate also moves with the rotation angle of the two sets of second flip plates. The connecting plate is flush with the bottom of the base frame. When the ground grid mechanism is laid out, the connecting plate contacts the ground and the support plate contacts the ground, thereby controlling the first flip plate to be perpendicular to the second flip plate. At the same time, the driven wheel at the bottom of the first flip plate also rolls on the base frame. After reaching the position, it fits against the base frame. The first limiting piece on both sides of the first connecting assembly limits the first support plate and the first flip plate, thereby effectively increasing the support strength of the support driven assembly and effectively solving the problem that the ground grid frame is prone to instability and tilting after the ground grid mechanism is laid out.

[0021] The design of the first support plate and the support driven component can effectively prevent the ground grid frame from being suspended in the middle due to the force on both sides when the hydraulic device pulls the connecting parts on both sides of the three sections. Long-term use will cause the middle of the ground grid frame to collapse and deform. Severe deformation will prevent the ground grid frame from being properly retracted and extended, thus causing the entire ground grid mechanism to become unusable due to severe deformation in the middle, resulting in serious cost waste.

Detailed Implementation

[0031] The technical solutions in the embodiments of the invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] In one specific embodiment of the present invention, such as Figures 1-7 As shown, a foldable ground net mechanism for a bumper car platform is specifically disclosed. The bumper car platform 1 has a ground net mechanism installed on one or both sides. A base frame 3 is provided below the ground net mechanism. The ground net mechanism includes a follower section 23, a driven section 22, and an active section 21 connected in sequence. All three sections are connected by a first connecting component 24. The follower section 23 is connected to the bumper car platform 1 through the first connecting component 24.

[0033] The bottom of the driven section 22 is provided with two sets of supporting driven components 27. One set of supporting driven components 27 is located at the connection between the driven section 22 and the driving section 21, and the other set of supporting driven components 27 is connected to the driven section 22. The bottoms of the two sets of supporting driven components 27 are connected by a connecting plate 26. The bottom of the driving section 21 is provided with several drive wheels 28. The drive wheels 28 are connected to a drive mechanism. The drive mechanism can be a set-type drive mechanism, which is installed on the outside of the shaft inside the drive wheel 28, thereby driving the drive wheel 28 to rotate. Alternatively, it can be an external drive mechanism. The output shaft of the drive mechanism passes through the second support plate 2142 and is connected to the shaft of the drive wheel 28 installed at its bottom. The drive mechanism drives the drive wheel 28 to roll on the base frame 3, causing the driving section 21, the driven section 22, and the follower section 23 to be flattened or folded.

[0034] The first connecting assembly 24 includes a first connecting shaft 241 and two first bushings 242 and a third bushing 244 sleeved on the first connecting shaft 241. A second bushing 243 is sleeved in the middle of the first connecting shaft 241. The two first bushings 242 are respectively disposed on both sides of the second bushing 243, and the two third bushings 244 are respectively disposed on both sides of the first bushing 242.

[0035] Each first connecting component 24 has a first limiting member on both sides, which is used to limit the first connecting shaft 241 after it is rotated to a specified position.

[0036] The active section 21 includes a first ground frame 211 and a second ground frame 212. The first ground frame 211 and the second ground frame 212 are fixedly connected to the outer sides of the first bushing 242 and the second bushing 243, respectively. Connecting members 213 for hooking the chain are provided on both sides of the junction of the three sections. A plurality of first hinge assemblies 214 are spaced apart at the bottom of the first ground frame 211. Each first hinge assembly 214 includes a linkage 2141 and a second support plate 2142. Each second support plate 2142... The top of the platform is connected to the first ground frame 211 via a linkage 2141, and the bottom is equipped with a drive wheel 28. The first ground frame 211 is connected to the top support of the bumper car platform 1 via a hook chain. The linkage 2141 includes a linkage shaft, a first linkage sleeve, and two second linkage sleeves. The first linkage sleeve is sleeved on the linkage shaft, and the two second linkage sleeves are respectively sleeved on both sides of the first linkage sleeve. The first linkage sleeve is welded and fixed to the first ground frame 211, and the two second linkage sleeves are welded and fixed to the second support plate 2142.

[0037] The driven section 22 includes a third ground frame 221 and a fourth ground frame 222. The third ground frame 221 and the second ground frame 212 are fixedly connected to the outer sides of the first bushing 242 and the second bushing 243, respectively. The third ground frame 221 and the fourth ground frame 222 are fixedly connected to the outer sides of the first bushing 242 and the second bushing 243, respectively. A first support plate 25 is fixed to the bottom of the second bushing 243 of the first connecting assembly 24 between the fourth ground frame 222 and the driven section 23. A second limiting member is provided between the fourth ground frame 222 and the driven section 23. The second limiting member is used to limit the first support plate 25.

[0038] Each support driven component 27 includes a first flip plate 271 and two second flip plates 272. The first flip plate 271 is connected to the two second flip plates 272 respectively through a second hinge component 273. A driven wheel 274 is installed at the bottom of the first flip plate 271. The structure of the second hinge component 273 is the same as that of the linkage 2141.

[0039] One set of first flip plates 271 is fixed to the second bushing 243 of the first connecting assembly 24 between the second ground grid 212 and the third ground grid 221, and the other set of first flip plates 271 is connected to the fourth ground grid 222 through the third hinge assembly 275.

[0040] The two sets of two second flip plates 272 are connected by connecting plates 26 respectively. The bottom of the connecting plate 26 is flush with the bottom of the base frame 3. The base frame 3 is a frame, and the connecting plate 26 is located inside the frame of the base frame 3. When the ground grid mechanism needs to be laid out, the connecting plate 26 contacts the ground, and the first support plate 25 contacts the ground, thereby controlling the first flip plate 271 to be perpendicular to the second flip plate 272. At the same time, the driven wheel 274 at the bottom of the first flip plate 271 also rolls on the base frame 3. After reaching the position, it fits against the base frame 3, thereby effectively increasing the support strength of the driven component 27 and effectively solving the problem that the ground grid frame is prone to instability and tilting after the ground grid mechanism is laid out.

[0041] The third hinge assembly 275 includes a fixing frame 2751 and a third hinge connecting shaft 2752. The fixing frame 2751 is fixedly installed inside the fourth ground frame 222, and its bottom is flush with the bottom of the fourth ground frame 222. Both ends of the third hinge connecting shaft 2752 are fitted with third hinge bushings 2753. The top of the third hinge connecting shaft 2752 is fixedly connected to the bottom of the fixing frame 2751. The bottoms of the two third hinge bushings 2753 are welded and fixed to the top of the first flip plate 271.

[0042] The workflow of this invention:

[0043] When the ground grid mechanism needs to be leveled, the hydraulic device extends the cables hooked to the connecting parts 213 on both sides of the first ground grid frame 211, thereby leveling the first ground grid frame 211. The cables are then removed, and the drive mechanism causes the drive wheel 28 to roll on the base frame 3, propelling the first ground grid frame 211 forward. The second ground grid frame 212 is leveled under gravity and pulling force, while the third ground grid frame 221 moves downwards under the action of pulling force and gravity. The driven wheel 274 rolls on the base frame 3 in the same direction as the drive wheel 28. Under the action of tension and gravity, the fourth ground grid 222 and the follower section 23 are flattened, the drive mechanism stops running, and the second bushing 243 and the first bushing 242 rotate on the first connecting shaft 241 to drive the fourth ground grid 222 and the follower section 23, which are welded and fixed to its outer side, to rotate. The second bushing 243 rotates on the first connecting shaft 241 to drive the first support plate 25, which is welded and fixed to the second bushing 243, to rotate, thereby making the first support plate 25 and the fourth ground grid 222 in a relatively flat position. In the vertical state, the first limiting members on both sides of the first connecting component 24 limit the first support plate 25, effectively preventing the first support plate 25 from tilting. At the same time, the connecting plate 26 contacts the ground, and the second bushing 243 and the first bushing 242 rotate on the first connecting shaft 241 to drive the third ground grid frame 221 and the second ground grid frame 212, which are welded and fixed to the outside of the second bushing 243 and the first bushing 242, to rotate. The second bushing 243 of the first connecting component 24 rotates on the first connecting shaft 241 to drive the first flip plate 271, which is fixed to the second bushing 243, to rotate accordingly and be perpendicular to the connecting plate 26. Both sets of first flip plates 271 and two second flip plates 272 are in a vertical state. The first limiting members on both sides of the first connecting component 24 limit the first flip plate 271, thereby effectively increasing the support strength of the driven component 27 and effectively solving the problem that the ground grid frame support is unstable and prone to tilting after the ground grid mechanism is laid out.

[0044] When the ground grid mechanism needs to be folded, the limiting pieces on both sides of each first connecting component 24 are released. Then, the hydraulic device uses the hook end of the cable to hook the connecting pieces 213 on both sides of the right side of the follower section 23, pulling up the middle. The first bushings 242 at both ends of the follower section 23 rotate on the first connecting shaft 241, and the second bushings 243, which are fixedly connected to the first support plate 25, rotate on the first connecting shaft 241. The follower section 23 and the fourth ground grid frame 222 fold and fit against the first support plate 25 respectively, hooking the hook end of the cable onto the driven section. 22 The rightmost two connecting parts 213, the hydraulic device pulls the cable, and the first bushing 242, which is fixedly connected to both ends of the third ground grid 221, rotates on the first connecting shaft 241. At the same time, the gravity of the connecting plate 26 drives the bottom set of third hinge bushings 2753 to rotate on the third hinge connecting shaft 2752, thereby driving the first flip plate 271 to rotate downward, thereby driving the upper set of second bushings 243 to rotate on the first connecting shaft 241, so as to drive the first flip plate 271, which is fixedly connected to it, to rotate downward. The flip plate 272 is flattened against the first flip plate 271, thereby folding the support driven component 27. Simultaneously, the third ground grid frame 221 and the second ground grid frame 212 also fold. The second ground grid frame 212 is then attached to the bottom of the connecting plate 26. Finally, the hook end of the cable is hooked onto the connecting pieces 213 on both sides of the first ground grid frame 211, and the first ground grid frame 211 is pulled up. The first bushing 242, fixed to the left side of the first ground grid frame 211, rotates on the first connecting shaft 241. When frame 211 is folded into a vertical position, the hydraulic device shortens the length of the cable, thereby hooking the first ground grid frame 211. The design of the first support plate 25 and the support driven component 27 can effectively prevent the ground grid frame from being suspended in the middle due to the force on both sides when the hydraulic device pulls the connecting parts 213 on both sides of the three sections. Long-term use will cause the ground grid frame to collapse and deform in the middle. Severe deformation will prevent the ground grid frame from being retracted and extended normally, thus causing the entire ground grid mechanism to become unusable due to severe deformation in the middle, resulting in serious cost waste.

[0045] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
