Description

Technical Field

[0001] The present invention relates to entertainment equipment, in particular to a gaming device. Background Art

[0002] The game device consists of four major components: a control device, a chassis, a column tube assembly, and an upper enclosure. To fold, the user directly operates the control device to release the constraints placed on the chassis. The user then lifts the control device upward, driving the now-unrestricted chassis. The linkage components between the chassis, column tube assembly, and upper enclosure further drive the column tube assembly and upper enclosure, allowing the game device to transition between the unfolded and folded states.

[0003] The column tube assembly (i.e., the "column tube assembly" in the "anti-tip children's entertainment device")—see the previous application "anti-tip children's entertainment device": The column tube assembly not only supports the entire game device but also incorporates a linkage mechanism to link the upper enclosure bar when the base bar assembly is folded. Existing linkage structures of this type have numerous components, complex coordination relationships between components, and are time-consuming to manufacture and assemble. Furthermore, these numerous components require high manufacturing precision to avoid cumulative errors. Furthermore, the linkage between these multiple components requires significant force to actuate. As a result, only a portion of the total force applied by the user is used to release the control device from locking the base frame assembly, with the remaining force serving only to drive the linkage of the internal components, making operation laborious. Summary of the Invention

[0004] The object of the present invention is to provide a gaming device which has a simple structure and is easy to operate.

[0005] The above-mentioned purpose of the present invention is achieved through the following technical solutions: a game device, comprising an upper enclosure assembly, a column tube assembly, a bottom opening and closing control device and a bottom frame assembly, wherein the upper enclosure assembly has an upper enclosure tube hingedly connected to the column tube assembly, the column tube assembly includes a column tube, and the bottom frame assembly includes an upper bottom frame tube and a lower bottom frame tube, characterized in that: the upper bottom frame tube and the lower bottom frame tube are arranged parallel to each other, one end of the upper bottom frame tube and the lower bottom frame tube are respectively hinged to the bottom opening and closing control device, and the other end is respectively hinged to the bottom end of the support column connecting rod which can move up and down along the axis of the column tube, forming four hinge points, the upper bottom frame tube, the lower bottom frame tube and the bottom The opening and closing control device and the support column connecting rod form a parallel four-bar linkage through the four hinge points, and the top end of the support column connecting rod is hinged to the upper surrounding tube. The device also has a lower folding connecting piece, the upper end of the lower folding connecting piece is hinged on the column tube, and the lower folding connecting piece is provided with an arc groove. The upper chassis tube is provided with a protrusion that extends into the arc groove and can slide along the arc groove. The upper chassis tube applies force to the lower folding connecting piece by sliding in the arc groove. The lower folding connecting piece serves as a force component, and when it is subjected to the force of the upper chassis tube, it will apply a reverse force to the upper chassis tube. After being subjected to the reverse force, the upper chassis tube drives the support column connecting rod to move.

[0006] When the cam is in the upright position, the lower frame tube and the lower frame tube are rotated, and the cam is moved in an opposite direction to the vertical direction, thereby realizing the camming of the cam.

[0007] In this device, the support column connecting rod is an important component and plays the role of a folding and unfolding linkage. The upper frame tube and the lower frame tube are respectively hinged to the support column connecting rod to form two hinge points, so that the lower end of the support column connecting rod is supported at two points. This two-point support ensures that the support column connecting rod must move smoothly in a horizontal translation manner when moving horizontally, that is, it ensures that the column tube that forms a constraint with the support column connecting rod in the horizontal direction (for example, the column tube is sleeved outside the support column connecting rod) can move smoothly in a horizontal translation manner when the device is folded or unfolded, and will not tilt or tip over.

[0008] The power for folding and unfolding the equipment comes only from the bottom opening and closing control device, which transmits the force to the upper chassis tube and the lower chassis tube, driving the upper chassis tube and the lower chassis tube to rotate. The lower folding connecting piece serves as a force component. When it is subjected to force from the upper chassis tube, it will apply a reverse force to the upper chassis tube. The upper chassis tube then transmits the force to the supporting column connecting rod through the force component lower folding connecting piece. On the one hand, the horizontal movement of the supporting column connecting rod drives the horizontal movement of the column tube. On the other hand, the upper surrounding tube is driven to rotate by the up and down movement of the supporting column connecting rod, thereby realizing the synchronous folding or unfolding of the upper chassis tube, the lower chassis tube, the column tube and the upper surrounding tube.

[0009] Since one end of the upper chassis tube is hinged on the support column connecting rod that moves up and down, and the force for the up and down movement of the support column connecting rod comes from the rotation of the upper chassis tube, the upper chassis tube needs to move up and down when rotating, and the movement trajectory (that is, the distance between the protrusion of the upper chassis tube and the hinge point A of the lower folding connection member and the column tube is changing) is relatively complex, and ultimately affects the displacement of the support column connecting rod when moving up and down and the offset in other directions. Not only can the support column connecting rod not maintain the best smoothness when moving up and down, it may also affect the coordination relationship of other components linked by the support column connecting rod. Therefore, based on the above, as a preferred embodiment of the present invention, the arc groove is an arc groove with the hinge point A of the lower folding connection member and the column tube as the center. In this embodiment, since the arc groove is a circular arc groove with the hinge point A as the center, the distance between the protrusion of the upper chassis tube, which can only slide along the circular arc groove, and the hinge point A is actually set to be constant, and the movement trajectory of the protrusion of the upper chassis tube is restricted to a circular arc shape with relatively simple force transmission, thereby better controlling the displacement of the support column connecting rod when it is linked and the offset in other directions.

[0010] Based on the above, the lower folding connector of the present invention includes a body having a cross-sectional shape and dimensions that match the cross-sectional shape and dimensions of the inner diameter of the column tube. The arc-shaped groove is provided in the body, and the support column connecting rod passes through the body so as to be able to move up and down. The lower folding connector component of this embodiment serves to constrain the movement trajectory of the upper chassis tube and also guides the vertical movement of the support column connecting rod, preventing it from shaking during movement.

[0011] In the present invention, the column tube assembly also includes a joint cover and a support foot. The top and bottom ends of the column tube are respectively inserted into the joint cover and the support foot, and are fixedly connected by a connecting piece. The connecting piece can be a screw. The end of the upper surrounding tube is hinged on the joint cover.

[0012] In the present invention, the top end of the support column link is hinged to the upper enclosure tube via an upper folding link. The upper end of the upper folding link is hinged to the upper enclosure tube, and the lower end is hinged to the top end of the support column link, interlocking with the support column link. When the support column link moves up and down, it drives the upper folding link to move, which in turn drives the upper enclosure tube to rotate, thereby achieving the synchronous folding or unfolding of the upper and lower chassis tubes, column tubes, and upper enclosure tubes.

[0013] In the present invention, the bottom end of the support column connecting rod extends from the column tube, and the protruding end is a bent portion arranged obliquely. The lower end of the column tube is provided with a column tube groove for the bent portion to pass through, and the column tube groove leaves space when the bent portion moves. The upper folding connecting rod is an oblique rod, and the bent portion and the inclined upper folding connecting rod are both used to simultaneously transmit vertical force and lateral force.

[0014] As a preferred embodiment, the lower end of the upper folding link is hinged to the support column link through a joint block, the joint block is fixedly sleeved on the top end of the support column link, and the lower end of the upper folding link is hinged to the joint block.

[0015] The joint block is added because the support column connecting rod needs to move up and down in the column tube. Under the premise of meeting the strength requirements of the support column connecting rod, the cross-section and weight should be reduced as much as possible. If the two upper folding connecting rods are directly hinged at the upper end of the narrow support column connecting rod, the processing accuracy requirements will be high. Adding a joint block with a wider cross-section at the top of the support column connecting rod can reduce the difficulty of component processing and installation to a certain extent.

[0016] In the present invention, the joint block is cylindrical, and after the joint block is fitted onto the top end of the support column connecting rod, it is fixedly connected through a connecting piece, which can be a screw; the joint block has an ear, and the lower end of the upper folding connecting rod is hinged to the ear of the joint block.

[0017] As a preferred embodiment, the support column connecting rod is further provided with an anti-interference groove vertically at a position corresponding to the hinge point between the lower folding connector and the column tube in the rod section located inside the column tube, so as to avoid interference with the hinge point when the support column connecting rod moves up and down, and the slot length of the anti-interference groove is greater than the displacement of the support column connecting rod when moving up and down.

[0018] In the present invention, the hinge point between the upper folding link and the upper surrounding tube is farther away from the joint cover than the hinge point between the upper surrounding tube and the joint cover, thereby preventing the upper folding link from interfering with the upper surrounding tube when folding or unfolding.

[0019] As a preferred embodiment, there are four upper surrounding tubes, column tubes and support column connecting rods. The four upper surrounding tubes form a rectangle. An upper folding connecting rod is fixedly installed on both sides of the top of each support column connecting rod. The angle between the projections of the two upper folding connecting rods on the horizontal plane is 90°.

[0020] In the present invention, the upper surrounding tube is a split tube, consisting of two sections hinged in the middle, which is convenient for folding. A locking mechanism is provided between the two sections of the upper surrounding tube, and one end of the steel cable of the locking mechanism is fixed to the joint block so that when the joint block is displaced, the steel cable is pulled to lock or unlock the locking mechanism. The bottom opening and closing control device is a base, and a pull rope or handle can also be provided on the base. The upper chassis tube is also equipped with an auxiliary support frame, which has an auxiliary support function and increases the stability of the device when it is deployed.

[0021] The device of the present invention includes an upper enclosure assembly, a column tube assembly, a bottom opening and closing control device, and a base frame assembly. The folding process is achieved by lifting the bottom opening and closing control device, applying an upward pulling force, which drives the upper and lower base frame tubes to rotate. The upper base frame tube drives the support column connecting rod to move, ultimately driving the upper enclosure tube of the upper enclosure assembly to fold. The deployment process is achieved by applying downward pressure to the bottom opening and closing control device, which drives the upper enclosure tube of the upper enclosure assembly through the support column connecting rod. Whether folding or deploying the entire children's entertainment device, a single operation is required, requiring only force to be applied to the base. This ensures that the column tube assembly will not tilt or tip over during horizontal movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figures 1 to 9 The game device shown in the figure includes an upper enclosure component, a column tube component, a bottom opening and closing control device and a bottom frame component. The upper enclosure component has an upper enclosure tube 301 hinged to the column tube component, the column tube component includes a column tube 306, and the bottom frame component includes an upper bottom frame tube 201 and a lower bottom frame tube 202. The upper bottom frame tube 201 and the lower bottom frame tube 202 are arranged parallel to each other. One end of the upper bottom frame tube 201 and the lower bottom frame tube 202 are respectively hinged to the bottom opening and closing control device, and the other end is respectively hinged to the bottom end of a support column connecting rod 209 that can move up and down along the axis of the column tube 306, forming four hinge points. The upper bottom frame tube 201, the lower bottom frame tube 202 and the bottom opening and closing control device and the support column connecting rod 209 are hinged through the four hinge points. The contacts form a parallel four-bar linkage, the top end of the support column connecting rod is hinged to the upper surrounding tube, and the equipment also has a lower folding connecting member 208, the upper end of the lower folding connecting member 208 is hinged on the column tube 306, the lower folding connecting member 208 is provided with an arc groove 2081, and the upper chassis tube 201 is provided with a protrusion 206 that extends into the arc groove 2081 and can slide along the arc groove 2081. The upper chassis tube 201 applies force to the lower folding connecting member 208 by sliding in the arc groove 2081. The lower folding connecting member 208 acts as a force component, and when it is subjected to force from the upper chassis tube 201, it will apply a reverse force to the upper chassis tube 201. After the upper chassis tube 201 is subjected to the reverse force, it drives the support column connecting rod 209 to move.

[0033] In the device of the present invention, the upper chassis tube 201, the lower chassis tube 202, the bottom opening and closing control device and the support column connecting rod 209 form a parallel four-bar linkage; when unfolding, downward pressure is applied to the bottom opening and closing control device, and the bottom opening and closing control device drives the upper chassis tube 201 and the lower chassis tube 202 to rotate. Due to the structural characteristics of the parallel four-bar linkage, the upper chassis tube 201 and the lower chassis tube 202 rotate and drive the support column connecting rod 209 to move upward and outward, synchronously driving the column tube assembly to move horizontally outward to unfold and the synchronous belt The upper surrounding tube 301 is driven to rotate to realize the deployment of the device components; the folding process is opposite to the deployment process. During folding, an upward lifting force is applied to the bottom opening and closing control device, and the bottom opening and closing control device drives the upper chassis tube 201 and the lower chassis tube 202 to rotate in the direction opposite to the direction of rotation during deployment. When the upper chassis tube 201 and the lower chassis tube 202 rotate, they drive the support column connecting rod 209 to move downward and inward, and simultaneously drive the column tube assembly to move horizontally inward and fold, and simultaneously drive the upper surrounding tube 301 to rotate, thereby realizing the folding of the device components.

[0034] In this device, the support column link 209 is an important component and plays the role of a folding linkage. The upper chassis tube 201 and the lower chassis tube 202 are respectively hinged to the support column link 209 to form two hinge points, so that the lower end of the support column link 209 is supported at two points. This two-point support ensures that the support column link 209 must move smoothly in a horizontal translation manner when moving horizontally, that is, it ensures that the column tube 306 (for example, the column tube is sleeved outside the support column link) that forms a constraint with the support column link 209 in the horizontal direction can move smoothly in a horizontal translation manner when the device is folded or unfolded, and will not tilt or tip over.

[0035] The power for folding and unfolding the equipment comes only from the bottom opening and closing control device, which transmits the force to the upper chassis tube 201 and the lower chassis tube 202, driving the upper chassis tube 201 and the lower chassis tube 202 to rotate. The lower folding connecting piece 208 acts as a force component. When it is subjected to force from the upper chassis tube 201, it will apply a reverse force to the upper chassis tube 201. The upper chassis tube 201 then transmits the force to the support column connecting rod 209 through the force component lower folding connecting piece 208. On the one hand, the horizontal movement of the support column connecting rod 209 drives the column tube 306 to move horizontally. On the other hand, the upper surrounding tube 301 is driven to rotate by the up and down movement of the support column connecting rod 209, thereby realizing the synchronous folding or unfolding of the upper chassis tube 201, the lower chassis tube 202, the column tube 306 and the upper surrounding tube 301.

[0036] Since one end of the upper chassis tube 201 is hinged on the support column link 209 that moves up and down, and the force for the up and down movement of the support column link 209 comes from the rotation of the upper chassis tube 201, the upper chassis tube 201 needs to move up and down when rotating. The movement trajectory (that is, the distance between the protrusion 206 of the upper chassis tube 201 and the hinge point A of the lower folding connection part 208 and the column tube 306 is changing) is relatively complex, and ultimately affects the displacement of the support column link 209 when moving up and down and the offset in other directions. Not only can the support column link 209 not maintain the best smoothness when moving up and down, it may also affect the coordination relationship of other components linked by the support column link 209. As a preferred embodiment of the present invention, the arc groove 2081 is a circular arc groove 2081 with the hinge point A of the lower folding connection part 208 and the column tube 306 as the center. In this embodiment, since the arc groove 2081 is a circular arc groove 2081 with the hinge point A as the center, the distance between the protrusion 206 of the upper chassis tube 201, which can only slide along the circular arc groove 2081, and the hinge point A is actually set to be constant, and the movement trajectory of the protrusion 206 of the upper chassis tube 201 is limited to a circular arc shape with relatively simple force transmission, so that the displacement of the support column link 209 when being linked and the offset in other directions can be better controlled.

[0037] In the present invention, lower folding connector 208 comprises a body whose cross-sectional shape and dimensions match those of the inner diameter of column tube 306. A circular arc-shaped groove 2081 is provided in the body, through which support column link 209 passes, allowing for vertical movement. Lower folding connector 208 of this embodiment serves to constrain the movement trajectory of upper chassis tube 201 and also guides the vertical movement of support column link 209, preventing it from shaking during movement.

[0038] In the present invention, the column tube assembly also includes a joint cover 308 and a support foot 204. The top and bottom ends of the column tube 306 are respectively inserted into the joint cover 308 and the support foot 204, and are fixedly connected by a connecting piece. The connecting piece can be a screw. The end of the upper surrounding tube 301 is hinged on the joint cover 308.

[0039] In the present invention, the top end of the support column link 209 is hinged to the upper surrounding tube 301 via the upper folding link 303. The upper end of the upper folding link 303 is hinged to the upper surrounding tube 301, and the lower end is hinged to the top end of the support column link 209, thereby interlocking with the support column link 209. When the support column link 209 moves up and down, it drives the upper folding link 303 to move, and then drives the upper surrounding tube 301 to rotate, thereby achieving the synchronous folding or unfolding of the upper chassis tube 201, the lower chassis tube 202, the column tube 306, and the upper surrounding tube 301.

[0040] In the present invention, the bottom end of the support column link 209 extends from the column tube 306, and the protruding end is an obliquely arranged bending portion 2091. The lower end of the column tube 306 is provided with a column tube groove 3061 for the bending portion 2091 to pass through. The column tube groove 3061 leaves space for the bending portion 2091 to move. The upper folding link 303 is an oblique rod. The bending portion 2091 and the inclined upper folding link 303 are both used to simultaneously transmit vertical force and lateral force.

[0041] As a preferred embodiment, the lower end of the upper folding link 303 is hinged to the support column link 209 through the joint block 305, the joint block 305 is fixedly mounted on the top of the support column link 209, and the lower end of the upper folding link 303 is hinged to the joint block 305.

[0042] The joint block 305 is added because the support column link 209 needs to move up and down in the column tube 306. Under the premise of meeting the strength requirements of the support column link 209, the cross-section and weight are reduced as much as possible. If the two upper folding links 303 are directly hinged on the upper end of the narrow support column link 209, high processing accuracy is required. Adding a joint block 305 with a wider cross-section on the top of the support column link 209 can reduce the difficulty of component processing and installation to a certain extent.

[0043] In the present invention, the joint block 305 is cylindrical, and the joint block 305 is mounted on the top of the support column connecting rod 209 and fixedly connected through a connecting piece, which can be a screw; the joint block 305 has an ear 3051, and the lower end of the upper folding connecting rod 303 is hinged to the ear 3051 of the joint block 305.

[0044] As a preferred embodiment, the support column link 209 is provided with an anti-interference groove 2092 vertically at a position corresponding to the hinge point between the lower folding connector 208 and the column tube 306 in the rod section located inside the column tube 306, so as to prevent the support column link 209 from interfering with the hinge point when moving up and down. The slot length of the anti-interference groove 2092 is greater than the displacement of the support column link 209 when moving up and down.

[0045] In the present invention, the hinge point between the upper folding link 303 and the upper surrounding tube 301 is farther away from the joint cover 308 than the hinge point between the upper surrounding tube 301 and the joint cover 308, so as to prevent the upper folding link from interfering with the upper surrounding tube when folding or unfolding.

[0046] As a preferred embodiment, there are four upper surrounding tubes 301, column tubes 306 and support column connecting rods 209. The four upper surrounding tubes 301 form a rectangle. An upper folding connecting rod 303 is fixedly installed on both sides of the top of each support column connecting rod 209. The angle between the projections of the two upper folding connecting rods 303 on the horizontal plane is 90°.

[0047] In the present invention, the upper surrounding tube 301 is a split tube, consisting of two sections hinged in the middle for easy folding. A locking mechanism is provided between the two sections of the upper surrounding tube. One end of the locking mechanism's steel cable 310 is fixed to the joint block 305, so that when the joint block 305 shifts, the steel cable 310 is pulled to lock or unlock the locking mechanism. The bottom opening and closing control device is a base 1, which can also be provided with a pull rope or handle. The upper chassis tube 201 is also equipped with an auxiliary support frame 4, which provides auxiliary support and increases the stability of the device when deployed.
