Description

Technical Field

[0001] This utility model relates to the field of toy vehicle technology, and in particular to an assembly-type transport vehicle toy. Background Technology

[0002] Children have a strong curiosity about various tools and vehicles with different shapes and special functions, so they like these kinds of vehicles. In order to cater to children's preferences, many toy vehicles of the tool vehicle type have appeared on the market. However, existing toy vehicles generally only have movable wheels, which have low playability, and children cannot learn the specific working principles through toys. Therefore, a new type of transport vehicle toy has been invented to solve this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an assembly-type transport vehicle toy.

[0005] To achieve the above objectives, the technical solution of this utility model is: an assembled transport vehicle toy, including a vehicle body, a platform, a rear cover, and a top plate. The two ends of the platform are respectively fixedly connected to a front bracket and a rear bracket. The top plate is disposed above the platform, and one end of the top plate is rotatably connected to the front bracket. The platform is provided with a support mechanism for supporting the top plate. One end of the rear cover is rotatably connected to the rear of the platform, and the other end of the rear cover is detachably connected to the rear bracket through a connecting mechanism.

[0006] By adopting the above technical solution, a transport vehicle is constructed by a top plate, a rear cover, and a platform to hold vehicles. The rear cover at the rear can be released and flipped through a connecting mechanism to form a ramp that allows the transported vehicle to drive onto the platform. The top plate can also be flipped downwards under the control of a support mechanism, so that one end abuts against the platform, allowing the transported vehicle to drive onto the top plate. In this way, the transport vehicle toy can have more assembly forms, thereby enhancing the playability of the transport vehicle toy car. At the same time, it can also allow children to experience the function of each part of the transport vehicle and learn the working principle of the transport vehicle.

[0007] Preferably, the support mechanism includes a sliding rod and a sliding cylinder, the sliding rod and the sliding cylinder being rotatably connected to the top plate and the platform, respectively. The sliding rod is slidably connected inside the sliding cylinder, and the platform is provided with a control mechanism for injecting or extracting gas into the sliding cylinder. This invention utilizes the control mechanism to inject or extract gas into the sliding cylinder, allowing the cylinder to slide under air pressure, thereby causing the top plate to flip. This method further enhances the playability of the transport vehicle and allows children to learn the principle of top plate lifting.

[0008] Preferably, the control mechanism includes a pressure column and an air cylinder, the pressure column being slidably connected to the air cylinder, and an elastic element being disposed between the pressure column and the air cylinder. The gas is connected to the slide cylinder through a switching mechanism for switching between pumping and injecting gas. This invention changes the volume inside the air cylinder by pushing the pressure column back and forth, thereby allowing gas from the air cylinder to be injected into or extracted from the slide cylinder. Pumping in and out is controlled by the switching mechanism. When the pressure column slides, it causes the elastic element to deform, so that when no pushing force is applied to the pressure column, it can rebound under the elastic force of the elastic element.

[0009] Preferably, two pressure columns are provided, and the two pressure columns are slidably connected to both ends of the air cylinder, with the elastic element disposed between the two pressure columns. This invention allows for simultaneous application of force to both sides of the air cylinder, making operation easier, and the two pressure columns also increase the efficiency of air injection and extraction.

[0010] Preferably, the switching mechanism includes a valve core, a valve body, and an air pipe. The valve body is fixedly connected to the platform. An air chamber is formed inside the valve body. The valve core is slidably connected within the air chamber. An elastic element is provided between the valve core and the valve body. The valve core has an annular groove. The valve body is fixedly connected to two connecting pipes (first), two connecting pipes (second), and two exhaust pipes. The two connecting pipes (first), two connecting pipes (second), and two exhaust pipes are all connected to the air chamber. The two connecting pipes (first) are all connected to the air cylinder. The two connecting pipes (second) are all connected to the air pipe. The air pipe is connected to the slide cylinder. One of the connecting pipes (second) and the exhaust pipe are each provided with a one-way valve (first). The other connecting pipe (second) and the exhaust pipe are provided with a one-way valve (second). The conduction directions between the one-way valves (first and second) are opposite. The connecting pipe (first) with the one-way valve (first), the exhaust pipe with the one-way valve (second), and one of the connecting pipes (first) are connected to the annular groove. The valve body is provided with a limiting mechanism for fixing and restricting the sliding of the valve core. This utility model's valve core is slidably connected within the air chamber, effectively sealing it and leaving only the space where the annular groove is located. In the initial state, one of the connecting pipes, a second connecting pipe with a check valve, and an exhaust pipe with a check valve are all connected to the annular groove. When the pressure column slides, causing the air cylinder to discharge gas, the gas can enter the annular groove through the first connecting pipe. At this time, check valve one is open, while check valve two is closed. Therefore, the gas only enters the air pipe through the second connecting pipe and then into the sliding cylinder. When the pressure column resets under the elastic force of the first elastic element, the air cylinder draws gas in. At this time, check valve two is open, check valve one is closed, and gas is drawn in through the exhaust pipe to replenish the air cylinder. Therefore, in this… In this state, air can be injected into the slide cylinder. By pushing the valve core to slide in the direction that overcomes the elastic force of the second elastic element, the second connecting pipe with the second one-way valve, the exhaust pipe with the first one-way valve, and another connecting pipe are connected to the annular groove. All other pipes in the previous state are blocked by the valve core. When the air cylinder draws air in, it will draw air into the slide cylinder through the second connecting pipe with the second one-way valve, and when it exhausts air, it will exhaust air out through the exhaust pipe with the first one-way valve. Therefore, the valve core can achieve air extraction from the slide in this state. After the valve core slides into place against the elastic force of the second elastic element, it will be fixed by the limiting mechanism and will not reset under the elastic force of the second elastic element. By releasing the limiting mechanism, the valve core can return to its original state.

[0011] Preferably, the limiting mechanism includes a limiting member and an elastic member three. The limiting member is slidably connected to the valve body, and the elastic member three is disposed between the limiting member and the valve body. The valve core has a limiting groove for the limiting member to engage. In the initial state, the limiting member presses against the valve core under the elastic force of the elastic member three. When the valve core slides into place, the limiting member aligns with the limiting groove on the valve core and engages in the limiting groove under the elastic force of the elastic member three, thereby limiting the valve core. The limiting of the valve core can be released by pushing the limiting member to slide in a direction that overcomes the elastic force of the elastic member three.

[0012] Preferably, the connecting mechanism includes a slot and a card, the card being fixedly connected to the back cover, and the slot being fixedly connected to the rear support. The slot has a groove for the card to be inserted. This invention utilizes the deformability of plastic to allow the card to be inserted into the groove of the slot, thereby fixing the back cover.

[0013] Preferably, the air tube is connected to the slide cylinder via a flexible hose. This invention utilizes the flexible hose to ensure that the rotation of the slide cylinder is not affected.

[0014] Preferably, a sealing sleeve is fixedly connected to the end of the slide rod. This invention utilizes the sealing sleeve to increase the airtightness between the slide rod and the slide cylinder.

[0015] In summary, the beneficial effects of this utility model are:

[0016] 1. The rear cover located at the tail can be released and flipped through the connecting mechanism to form a ramp that allows the transported vehicle to drive onto the platform. The top plate can also be flipped downwards through the control of the support mechanism so that one end abuts against the platform, allowing the transported vehicle to drive onto the top plate. In this way, the transport vehicle toy can have more assembly forms, thereby enhancing the playability of the transport vehicle toy.

[0017] 2. By injecting or extracting gas into the sliding cylinder using the control mechanism, the cylinder can slide under air pressure, thereby causing the top plate to flip. This method can further enhance the playability of the transport vehicle.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0034] like Figure 1-5 As shown, an assembled transport vehicle toy includes a vehicle body 1, a platform 2, a rear cover 3, and a top plate 4. The two ends of the platform 2 are respectively fixedly connected to a front support 5 and a rear support 6. The top plate 4 is located above the platform 2, and one end of the top plate 4 is rotatably connected to the front support 5. The platform 2 is provided with a support mechanism for supporting the top plate 4. One end of the rear cover 3 is rotatably connected to the rear of the platform 2, and the other end of the rear cover 3 is detachably connected to the rear support 6 through a connecting mechanism.

[0035] By adopting the above technical solution, the top plate 4, the rear cover 3, and the platform 2 are used to form a carriage for placing vehicles. The rear cover 3 at the rear can be released and flipped through the connecting mechanism to form a ramp that allows the transported vehicle to drive onto the platform 2. The top plate 4 can also be flipped downwards under the control of the support mechanism so that one end abuts against the platform 2, allowing the transported vehicle to drive onto the top plate 4. In this way, the transport vehicle toy can have more assembly forms, thereby enhancing the playability of the transport vehicle toy car. At the same time, it can also allow children to experience the function of each part of the transport vehicle and learn the working principle of the transport vehicle.

[0036] The support mechanism includes a slide rod 7 and a slide cylinder 8, which are rotatably connected to the top plate 4 and the platform 2, respectively. The slide rod 7 is slidably connected inside the slide cylinder 8. The platform 2 is equipped with a control mechanism for injecting or extracting gas into the slide cylinder 8. Injecting or extracting gas into the slide cylinder 8 using the control mechanism allows the slide cylinder 8 to slide under air pressure, thereby causing the top plate 4 to flip. This method further enhances the playability of the transport vehicle and allows children to learn the principle of how the top plate 4 is raised.

[0037] The control mechanism includes a pressure column 9 and an air cylinder 10. The pressure column 9 and the air cylinder 10 are slidably connected, and an elastic element 11 is provided between the pressure column 9 and the air cylinder 10. Gas is connected to the slide cylinder 8 through a switching mechanism for switching between evacuation and injection. By pushing the pressure column 9 to slide back and forth, the volume inside the air cylinder 10 is changed, thereby allowing gas in the air cylinder 10 to be injected into or extracted from the slide cylinder 8. The injection and extraction are controlled by the switching mechanism. When the pressure column 9 slides, it pushes the elastic element 11 to deform, so that when no thrust is applied to the pressure column 9, it can rebound under the elastic force of the elastic element 11.

[0038] There are two pressure columns 9, which are slidably connected to both ends of the air cylinder 10. An elastic element 11 is disposed between the two pressure columns 9. In this way, force can be applied to both sides of the air cylinder 10 at the same time, which makes operation easier. At the same time, the two pressure columns 9 can also increase the efficiency of air injection and air extraction.

[0039] The switching mechanism includes a valve core 12, a valve body 13, and an air pipe 14. The valve body 13 is fixedly connected to the platform 2. An air chamber is formed inside the valve body 13, and the valve core 12 is slidably connected inside the air chamber. An elastic element 2 15 is provided between the valve core 12 and the valve body 13. The valve core 12 has an annular groove 21. The valve body 13 is fixedly connected to two connecting pipes 16, two connecting pipes 17, and two exhaust pipes 1814. The two connecting pipes 16, 17, and 1814 are all connected to the air chamber. The two connecting pipes 16 are all connected to the air cylinder 10. All connecting pipes 17 are connected to the air pipe 14, which is connected to the slide cylinder 8. One-way valve 19 is installed in one of the connecting pipes 17 and the exhaust pipe 1814, and one-way valve 20 is installed in the other connecting pipe 17 and the exhaust pipe 1814. The conduction directions between one-way valve 19 and one-way valve 20 are opposite. Connecting pipe 16 with one-way valve 19 and exhaust pipe 1814 with one-way valve 20, as well as one of the connecting pipes 16, are connected to the annular groove 21. The valve body 13 is provided with a limiting mechanism for fixing and restricting the sliding of the valve core 12. The valve core 12 is slidably connected within the air chamber, effectively sealing it and leaving only the space where the annular groove 21 is located. Initially, one of the connecting pipes, 16, 17 (with a check valve 19), and 1814 (with a check valve 20), are all connected to the annular groove 21. When the pressure column 9 slides, causing the air cylinder 10 to discharge gas, the gas can enter the annular groove 21 through the connecting pipe 16. At this time, the check valve 19 is open, while the check valve 20 is closed. Therefore, the gas only enters the air pipe 14 through the connecting pipe 27 and then into the slide cylinder 8. When the pressure column 9 resets under the elastic force of the elastic element 11, the air cylinder 10 draws gas in. At this time, the check valve 20 is open, and the check valve 19 is closed. The gas is then drawn in through the exhaust pipe 1814 to replenish the air cylinder 10. Therefore, in... In this state, air can be injected into the slide cylinder 8. By pushing the valve core 12 to slide in the direction that overcomes the elastic force of the second elastic element 15, the connecting pipe 17 with the second check valve 20, the exhaust pipe 1814 with the first check valve 19, and another connecting pipe 16 are connected to the annular groove 21. All other pipes in the previous state are blocked by the valve core 12. When the air cylinder 10 draws air in, it will draw air into the slide cylinder 8 through the connecting pipe 17 with the second check valve 20. When it exhausts air, it will exhaust air outward through the exhaust pipe 1814 with the first check valve 19. Therefore, the valve core 12 can achieve air extraction in this state. After the valve core 12 slides into place against the elastic force of the second elastic element 15, it will be fixed by the limiting mechanism and will not reset under the elastic force of the second elastic element 15. By releasing the limiting mechanism, the valve core 12 can return to its original state.

[0040] The limiting mechanism includes a limiting member 22 and an elastic member 23. The limiting member 22 is slidably connected to the valve body 13, and the elastic member 23 is disposed between the limiting member 22 and the valve body 13. The valve core 12 has a limiting groove 24 for the limiting member 22 to engage. In the initial state, the limiting member 22 will press against the valve core 12 under the elastic force of the elastic member 23. When the valve core 12 slides into place, the limiting member 22 will align with the limiting groove 24 on the valve core 12 and engage with the limiting groove 24 under the elastic force of the elastic member 23, thereby limiting the valve core 12. The limiting of the valve core 12 can be released by pushing the limiting member 22 to slide in a direction that overcomes the elastic force of the elastic member 23.

[0041] The connecting mechanism includes a slot 25 and a card 26. The card 26 is fixedly connected to the back cover 3, and the slot 25 is fixedly connected to the rear bracket 6. The slot 25 has a slot for the card 26 to be inserted. The card 26 is inserted into the slot of the slot 25 by utilizing the deformability of the plastic, thereby fixing the back cover 3.

[0042] The trachea 14 is connected to the slide 8 via the hose 27. The hose 27 ensures that the rotation of the slide 8 is not affected.

[0043] A sealing sleeve is fixedly connected to the end of the slide rod 7. The sealing sleeve can increase the airtightness between the slide rod 7 and the slide cylinder 8.

[0044] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
