Description

Technical Field

[0001] This utility model relates to a bubble car. Background Technology

[0002] There is a wide variety of bubble toys available. One common type is the manual bubble blower, which requires continuous manual operation from the user. This not only requires considerable effort but also results in a limited quantity and continuity of bubbles produced. Electric bubble machines, while automated, typically require an external power source or frequent battery replacements, limiting their use and lacking in fun and interactivity. Furthermore, most bubble machines are handheld or stationary, meaning their movement and bubble production functions are independent. They cannot automatically and continuously produce bubbles while in motion, further limiting their applications, especially in scenarios where children are riding or pushing toy cars.

[0003] Currently, although some designs attempt to combine bubble generating devices with vehicles, such as simply attaching them to the back of bicycles or toy cars, their operation still relies on manual or additional electricity, resulting in unstable bubble production and high costs.

[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of bubble car that uses the vehicle's own motion as a power source, has a compact structure, reliable linkage, and can automatically and continuously generate abundant bubbles, thereby enhancing its fun and expanding its application scenarios.

[0006] This utility model is achieved through the following technical solution:

[0007] A bubble car includes a frame body with wheels, a storage tank for holding bubble solution connected to the frame body, a rotating frame that can rotate inside the storage tank and be coated with bubble solution, a plurality of through holes along the circumference of the rotating frame, a shell connected to the frame body, a transmission mechanism connected to the wheels and driven to rotate by the wheels, a first linkage mechanism connected to the transmission mechanism and the rotating frame and capable of driving the rotating frame to rotate, a fan blade inside the shell, a second linkage mechanism connected to the fan blade and the transmission mechanism and capable of driving the fan blade to rotate, an air duct for airflow generated by the fan blade to flow through inside the shell, an air outlet located above the liquid surface in the storage tank and capable of blowing airflow outward from the inside of the through holes, and a bubble outlet on the shell for bubbles to float out when the airflow blows bubbles out of the outlet.

[0008] The vehicle frame includes a main frame, a steering assembly at the front of the main frame, and a rear frame at the rear of the main frame. The wheels include a front wheel located at the lower end of the steering assembly and a rear wheel located on the rear frame. The rear frame includes a laterally extending extension tube. The transmission mechanism includes a wheel axle located within the extension tube. The wheel axle is connected to the rear wheel and can rotate with it. The wheel axle has a rotating seat that can rotate with it. A first bevel gear is located on one side of the rotating seat. The extension tube has a slot for the first bevel gear to protrude. The housing has a rotating shaft that can rotate relative to it. The lower end of the rotating shaft has a second bevel gear that extends into the slot and can mesh with the first bevel gear. The upper end of the rotating shaft has a transmission gear set. The transmission gear set is connected to a first linkage mechanism and a second linkage mechanism respectively.

[0009] The extension tube is provided with an operating block that is connected to the rotating seat and can push the rotating seat to slide laterally along the wheel axle. When the rotating seat slides laterally, the first bevel gear engages or disengages from the second bevel gear.

[0010] The extension tube is provided with a positioning mechanism that can position the rotating seat when the first bevel gear and the second bevel gear are engaged or disengaged. The positioning mechanism includes a positioning seat fixed on the extension tube. The positioning seat is provided with a transverse through groove. The operating block is located in the through groove and can slide in the through groove. The groove wall of the through groove is provided with a first locking position and a second locking position. The operating block is provided with a locking part that can engage with the first locking position or the second locking position after it slides. When the locking part engages with the first locking position, the first bevel gear and the second bevel gear mesh. When the locking part engages with the second locking position, the first bevel gear and the second bevel gear disengage.

[0011] The housing further includes an inner housing, which comprises a lower inner shell. The first linkage mechanism, the second linkage mechanism, and the transmission gear set are disposed within the lower inner shell. The transmission gear set includes a first transmission gear connected to a rotating shaft. The first linkage mechanism includes a first linkage gear capable of driving the rotating frame to rotate. The second linkage mechanism includes a second linkage gear capable of driving the fan blade to rotate. A third transmission gear meshes with the first and second linkage gears. The lower inner shell also contains a second transmission gear that meshes with the first transmission gear and can swing relative to the lower inner shell. When the first transmission gear rotates in the forward direction, it drives the second transmission gear to rotate and pushes the second transmission gear to swing until it meshes with the first linkage gear. When the first transmission gear rotates in the reverse direction, it drives the second transmission gear to rotate and pushes the second transmission gear to swing until it meshes with the third transmission gear.

[0012] The first linkage gear is connected to a worm gear that rotates with it, and a worm wheel that cooperates with it is connected to the worm gear. The worm wheel shaft is connected to the rotating frame.

[0013] The fan blade is connected to a third linkage gear, and at least one fourth linkage gear is provided between the third linkage gear and the second linkage gear.

[0014] The rotating frame includes a rotating plate, and the outer periphery of the rotating plate is provided with an annular frame extending to one side. The through hole is provided on the annular frame along the circumferential direction, and the air outlet is arranged facing upward and located inside the annular frame so as to be opposite to the through hole.

[0015] The housing includes a lower housing and an upper cover. The liquid storage tank is located inside the housing. The bubble outlet is located on the upper cover. The upper cover is also provided with an injection port for adding bubble liquid to the liquid storage tank. A plug that can seal the injection port is connected to the upper cover.

[0016] The inner shell also includes an inner upper shell connected to the inner lower shell, and the fan blades and air ducts are located on the inner upper shell.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. When the bubble car of this invention is controlled, its wheels rotate and move forward. The wheels drive the transmission mechanism, which in turn drives the rotating frame to rotate via a first linkage mechanism. Simultaneously, the transmission mechanism drives the fan blades to rotate via a second linkage mechanism. During rotation, the rotating frame absorbs bubble solution from the storage tank and forms a liquid film at the through-hole. The rotating fan blades generate airflow, which passes through the air duct and blows the liquid film out through the air outlet inside the through-hole, thus producing abundant bubbles. Therefore, this bubble car of this invention uses the vehicle's own movement as a power source, eliminating the need for additional batteries or other power mechanisms. It has a compact structure, reliable linkage, and can automatically and continuously produce abundant bubbles, enhancing its fun factor.

[0019] 2. When the first and second bevel gears of this invention mesh, the rotational motion of the wheel is transmitted to the rotating frame and the fan blades, causing them to rotate and generate bubbles. When the first and second bevel gears are disengaged by the operating block, the rotational motion of the wheel is no longer transmitted to the rotating frame and the fan blades, and bubbles are no longer generated. Therefore, users can control the operation according to their needs to determine whether bubbles are generated at the desired time and place.

[0020] 3. This utility model has a simple and compact structure, which transmits the rotational motion of the wheel to the rotating frame and the fan blade, so that when children ride the bubble car, a liquid film can be formed on the rotating frame and the airflow required to blow bubbles can be generated. The design is very ingenious and suitable for widespread application. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1 to 8As shown, a bubble car includes a frame body 1 with wheels. The frame body 1 can be a tricycle, a two-wheeled vehicle, or other rideable vehicles. In this embodiment, the frame body 1 is a tricycle body. The frame body 1 is connected to a storage tank 2 for holding bubble solution. The storage tank 2 has a rotating frame 3 that can rotate inside and be coated with bubble solution. The rotating frame 3 has multiple through holes 4 along the circumferential direction. The frame body 1 is also connected to a shell 5. The bubble car also includes a transmission mechanism 6 that is connected to the wheels and can be driven to rotate by the wheels when the wheels rotate. The transmission mechanism 6 and the rotating frame 3 are connected to each other and can drive the rotating frame 3 to rotate. The shell 5 also has a fan blade 9. The fan blade 9 and the transmission mechanism 6 are connected to each other and can drive the fan blade 9 to rotate. The shell 5 also has a duct 10 for the airflow generated by the fan blade 9 to flow through. The outer end of the duct 10 has an air outlet 11 located above the liquid surface of the storage tank 2 and can blow air out from the inside of the through holes 4. The shell 5 also has a bubble outlet 12 for the bubbles to float out when the airflow blows out of the air outlet 11. When the bubble car is controlled, its wheels rotate and move forward, driving the transmission mechanism 6. The transmission mechanism 6, through the first linkage mechanism 7, drives the rotating frame 3 to rotate. Simultaneously, the transmission mechanism 6, through the second linkage mechanism 8, drives the fan blade 9 to rotate. During rotation, the rotating frame 3 absorbs bubble solution from the liquid tank 2 and forms a liquid film at the through hole 4. The rotation of the fan blade 9 generates airflow, which passes through the air duct 10 and blows the air out of the air outlet 11 inside the through hole 4 onto the liquid film, thus producing abundant bubbles. The bubble car uses the vehicle's own motion (wheel rotation) as its power source, eliminating the need for additional batteries or other power mechanisms. It has a compact structure, reliable linkage, and can automatically and continuously produce abundant bubbles, enhancing the fun for children riding and playing.

[0033] like Figure 1As shown, the main frame 1 includes a main frame 101, a steering assembly 102 at the front of the main frame 101, and a rear frame 103 at the rear of the main frame 101. The wheels include a front wheel 131 located at the lower end of the steering assembly 102 and two rear wheels 132 mounted on the rear frame 103. The rear frame 103 includes a laterally extending extension tube 1031. The transmission mechanism 6 includes a wheel axle 61 housed within the extension tube. The wheel axle 61 is connected to the rear wheels 132 and can rotate with the rear wheels 132. A rotating seat 62 is provided on the axle 61, which can rotate with it. A first bevel gear 63 is provided on one side of the rotating seat 62. The extension tube 1031 has a slot 1032 for the first bevel gear 63 to be exposed. A rotating shaft 64 is provided on the housing 5, which can rotate relative to it. A second bevel gear 65 is provided at the lower end of the rotating shaft 64, which extends into the slot 1032 and can mesh with the first bevel gear 63. A transmission gear set 66 is provided at the upper end of the rotating shaft 64. The transmission gear set 66 is connected to the first linkage mechanism 7 and the second linkage mechanism 8 respectively. When the child controls the steering component 102 to ride the bubble car, the rear wheel 132 rotates together with the wheel axle 61. The wheel axle 61 drives the rotating seat 62 on it to rotate. The first bevel gear 63 rotates along with it. The first bevel gear 63 drives the second bevel gear 65 to rotate, thereby changing the direction of rotation. This allows the entire bubble car to produce bubbles while ensuring that the bubble car structure is compact. The rotation of the second bevel gear 65 drives the transmission gear set 66 to rotate, which in turn drives the first linkage mechanism 7 and the second linkage mechanism 8 to move, thereby causing the rotating frame 3 and the fan blade 9 to rotate. Finally, the airflow generated by the fan blade 9 blows bubbles out at the through hole 4 of the rotating frame 3.

[0034] like Figures 8 to 10 As shown, the extension tube 1031 is equipped with an operating block 14 connected to the rotating seat 62 and capable of pushing the rotating seat 62 to slide laterally along the wheel axle 61. When the rotating seat 62 slides laterally, the first bevel gear 63 and the second bevel gear 65 engage or disengage. When the first bevel gear 63 and the second bevel gear 65 are engaged, the rotational motion of the rear wheel 132 is transmitted to the rotating frame 3 and the fan blade 9, causing them to rotate and generate bubbles. When the first bevel gear 63 and the second bevel gear 65 are disengaged by the operating block 14, the rotational motion of the rear wheel 132 is not transmitted to the rotating frame 3 and the fan blade 9, and bubbles are no longer generated. Therefore, the user can control the operation according to their needs to determine whether bubbles are generated at the desired time and place.

[0035] like Figures 8 to 10As shown, the extension tube 1031 is provided with a positioning mechanism 15 that can position the rotating seat 62 when the first bevel gear 63 and the second bevel gear 65 are engaged or disengaged. The positioning mechanism 15 includes a positioning seat 151 fixed on the extension tube 1031. The positioning seat 151 is provided with a transverse through groove 152. The operating block 14 is provided in the through groove 152 and can slide in the through groove 152. The groove wall of the through groove 152 is provided with a first locking position 154 and a second locking position 155. The operating block 14 is provided with a locking part 153 that can engage with the first locking position 154 or the second locking position 155 after it slides. When the locking part 153 engages with the first locking position 154, the first bevel gear 63 and the second bevel gear 65 mesh. When the locking part 153 engages with the second locking position 155, the first bevel gear 63 and the second bevel gear 65 disengage. When the child is riding and bubbles are not needed, the operating block 14 is pushed, and the engaging part 153 on the operating block 14 disengages from the first locking position 154. The operating block 14 moves laterally along with the rotating seat 62, and the first bevel gear 63 moves laterally with the rotating seat 62, disengaging from the second bevel gear 65, until the engaging part 153 engages and is positioned with the second locking position 155. At this point, the disengaged state of the first bevel gear 63 and the second bevel gear 65 is maintained. In this embodiment, the first locking position 154 and the second locking position 155 are open slots, and the engaging part 153 is a protrusion with an arc surface. When the operating block 14 is moved, the protrusion disengages from the open slot through elastic deformation by compression.

[0036] like Figure 5 , Figure 6 and Figure 7As shown, the housing 5 also includes an inner housing 16, which comprises a lower inner housing 161. The first linkage mechanism 7, the second linkage mechanism 8, and the transmission gear set 66 are disposed within the lower inner housing 161. The transmission gear set 66 includes a first transmission gear 661 connected to the rotating shaft 64. The first linkage mechanism 7 includes a first linkage gear 71 capable of driving the rotating frame 3 to rotate. The second linkage mechanism 8 includes a second linkage gear 81 capable of driving the fan blade 9 to rotate. The first linkage gear 71 and the second linkage gear 81 are provided with a meshing mechanism. The third transmission gear 663, and the inner lower shell 161 is also provided with a second transmission gear 662 that meshes with the first transmission gear 661 and can swing relative to the inner lower shell 161. When the first transmission gear 661 rotates in the forward direction, the first transmission gear 661 drives the second transmission gear 662 to rotate and pushes the second transmission gear 662 to swing until it meshes with the first linkage gear 71. When the first transmission gear 661 rotates in the reverse direction, the first transmission gear 661 drives the second transmission gear 662 to rotate and pushes the second transmission gear 662 to swing until it meshes with the third transmission gear 663. When the bubble car moves forward, the first transmission gear 661 rotates in the forward direction. The first transmission gear 661 drives the second transmission gear 662 to rotate in the reverse direction and pushes the second transmission gear 662 to swing until it meshes with the first linkage gear 71. At this time, the second transmission gear 662 disengages from the third transmission gear 663. The second transmission gear 662 drives the first linkage gear 71 to rotate in the forward direction. The first linkage gear 71 drives the rotating frame 3 to rotate. At this time, the first linkage gear 71 drives the third transmission gear 663 to rotate in the reverse direction. The third transmission gear 663 then drives the second linkage gear 81 to rotate in the forward direction. The second linkage gear 81 drives the fan blade 9 to rotate. When the bubble car moves backward, the first transmission gear 661 rotates in the opposite direction. This drives the second transmission gear 662 to rotate forward, causing it to swing until it engages with the third transmission gear 663. At this point, the second transmission gear 662 disengages from the first linkage gear 71. The second transmission gear 662 then drives the third transmission gear 663 to rotate in the opposite direction. The third transmission gear 663 then drives the first linkage gear 71 to rotate forward. The first linkage gear 71 then drives the rotating frame 3 to rotate, and simultaneously, the third transmission gear 663 drives the second linkage gear 81 to rotate forward. The second linkage gear 81 then drives the fan blade 9 to rotate. Therefore, regardless of whether the bubble car moves forward or backward, the rotation direction of the second linkage gear 81 is fixed, meaning the rotation direction of the fan blade 9 is always fixed. This avoids the drawback of the fan blade 9 rotating in the opposite direction, which would result in a smaller airflow. This ensures that whether the bubble car moves forward or backward, there is sufficient airflow to produce abundant bubbles.

[0037] like Figure 6 and Figure 7As shown, the first linkage gear 71 is connected to a worm 72 that rotates with it, and the worm 72 is connected to a worm wheel 73 that cooperates with it, thereby reducing the speed to ensure that the rotating frame 3 rotates at a suitable speed. The worm wheel shaft of the worm wheel 73 is connected to the rotating frame 3.

[0038] like Figure 6 and Figure 7 As shown, a third linkage gear 82 is connected to the fan blade 9, and at least one fourth linkage gear 83 is provided between the third linkage gear 82 and the second linkage gear 81. Through the cooperation of the first linkage mechanism 7 and the second linkage mechanism 8, the rotation speed of the rotating frame 3 and the airflow are appropriate, thereby ensuring that continuous and uniform bubbles are blown out.

[0039] like Figure 7 As shown, the rotating frame 3 includes a rotating plate 31. The outer periphery of the rotating plate 31 is provided with an annular frame 32 extending to one side. The through hole 4 is provided on the annular frame 32 along the circumferential direction. The air outlet 11 is arranged facing upward and located inside the annular frame 32 so as to be opposite to the through hole 4, so as to ensure that continuous and uniform bubbles are blown out.

[0040] like Figures 1 to 6 As shown, the housing 5 includes a lower housing 51 and an upper cover 52. The liquid storage tank 2 is located inside the housing 5. The bubble outlet 12 is located on the upper cover 52. The upper cover 52 is also provided with an injection port 53 for adding bubble liquid to the liquid storage tank 2. A plug 54 is connected to the upper cover 52 to seal the injection port 53 to prevent the bubble liquid from spilling out when the bubble car is moving.

[0041] like Figures 1 to 6 As shown, the inner shell 16 also includes an inner upper shell 162 connected to the inner lower shell 161. The fan blade 9 and the air duct 10 are provided on the inner upper shell 162, thus making the entire bubble car structure simple and compact.

[0042] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
