Description

Technical Field

[0001] This utility model relates to the technical field of toy cars, and more specifically to an amphibious toy racing car. Background Technology

[0002] Toy racing cars are used on a set track, where drivers maneuver them to complete the course, achieving both racing and recreational functions. Therefore, current technology often requires the design and configuration of the racing cars based on the track structure and conditions. Existing toy racing tracks are commonly land-based, using obstacles to regulate the cars and enhance entertainment. Some toy racing cars are also used on water tracks, commonly for wading races. To prevent water from entering the car, existing toy racing cars typically use sealing gaskets between the top and bottom covers. However, the axles, wheel hubs, and the locations of switches and function buttons are not waterproofed. In wading races, ordinary toy racing cars often become unable to continue due to water ingress.

[0003] For example, Chinese utility model patent No. 201920531432.3 discloses a waterproof structure for a children's car, including an upper shell and a lower shell connected by bolts. The upper shell covers the upper side of the lower shell and forms a bottom compartment chamber for placing a circuit board between the upper shell and the lower shell. The lower shell includes a concave cavity for forming the bottom compartment chamber and has an opening at the top. The top of the concave cavity is provided with a slot. The slot is a concave groove located on the top of the side wall of the concave cavity and has an opening facing away from the bottom of the concave cavity. A closed sealing ring is filled in the slot. The upper shell includes a cover plate that is pressed against the top of the side wall of the concave cavity and seals the top of the concave cavity. The sealing ring seals against the bottom of the cover plate. The cover plate is provided with a through hole for cables connected to the circuit board to pass through. This utility model has a simple structure and better waterproof performance. As can be seen from the above, this patent seals the mating parts of the upper and lower shells with a sealing ring, but does not waterproof the wheel axle and wheel hub. Therefore, after the vehicle body is submerged in water, moisture can still easily enter the interior from the wheels and wheel axles, affecting the electronic components inside the race car and causing damage and failure. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an amphibious toy race car with better waterproof performance and suitable for use on both land and water.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An amphibious toy race car includes a sealing ring, an upper shell, a lower shell, a frame, and a wheel assembly. The frame has a support extending to the side, and the wheel assembly has an extending axle that passes through the support and rotates with it. The upper and lower shells are respectively provided with fixing seats on their sides. The fixing seats of the upper shell and the lower shell together form a fixing opening for the support seat to be inserted. The support seat is inserted into the fixing opening and seals with it. The periphery of the upper shell covers the periphery of the lower shell. The sealing ring is continuously sealed between the periphery of the upper shell and the periphery of the lower shell, and the sealing ring is at least partially wrapped around the outside of the support seat.

[0007] Preferably, a sealing ring is provided around the outer periphery of the support base, and the sealing ring is placed between the upper shell and the lower shell and is in a sealing fit with the upper shell and the lower shell.

[0008] Preferably, the sealing ring is at least partially wrapped around the outside of the sealing ring, and the sealing ring and the sealing ring are in a sealing fit.

[0009] Preferably, the outer periphery of the support base is provided with an installation ring groove, and the sealing ring is fitted into and embedded in the installation ring groove.

[0010] Preferably, a reinforcing ring protrudes from the side of the sealing ring, the thickness of the reinforcing ring being less than the thickness of the sealing ring, and the reinforcing ring pressing against the groove wall of the mounting ring groove.

[0011] Preferably, the protrusion height of the reinforcing ring gradually decreases from the outside to the inside, and the cross-section of the reinforcing ring is conical.

[0012] Preferably, the two walls of the mounting ring groove are respectively set as inclined walls, and the two inclined walls are opposite to each other, so that the cross section of the mounting ring groove forms an inverted cone shape that is wider on the outside and narrower on the inside, and the inclined walls are squeezed and abutted against the reinforcing ring.

[0013] Preferably, the lower shell has a positioning protrusion on its periphery, the upper shell has a positioning groove on its periphery, and the sealing ring is pressed between the positioning groove and the positioning protrusion.

[0014] Preferably, a resilient button extends from the frame, and the upper shell has an opening for the resilient button to extend. At least one annular retaining wall is provided around the outer perimeter of the opening. Correspondingly, at least one annular groove is provided on the frame for the sealing insertion of the annular retaining wall.

[0015] Preferably, the resilient button includes a button head and an elastic body, the elastic body being in close contact with at least one of the annular retaining wall and the inner wall of the upper shell around the opening, and the opening being funnel-shaped with a smaller outer side and a larger inner side.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention utilizes an upper shell, lower shell, and frame to allow the support base to extend through the fixing opening between the upper and lower shells, thus enhancing overall waterproof sealing. Furthermore, continuous sealing rings directly seal the gap between the upper and lower shells, providing comprehensive waterproofing. Notably, even the support base itself has a sealing ring partially surrounding it, ensuring a seal across the upper shell, lower shell, and wheel assembly. Crucially, the support base itself is also sealed to the fixing bases of the upper and lower shells. This design allows for high-speed operation in wading, and high-pressure water is unlikely to penetrate the upper and lower shells, preventing damage to the toy race car from water ingress. It is highly suitable for racing tracks with both wading and land environments, enabling stable amphibious use and providing a superior play experience. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] like Figure 1-2The amphibious toy race car shown includes a sealing ring 3, an upper shell 1, a lower shell 2, a frame 4, and a wheel assembly 5. The frame 4 has a support seat 41 extending to the side, and the wheel assembly 5 has an extending axle 51. The axle 51 passes through the support seat 41 and rotates with the support seat 41. The upper shell 1 and the lower shell 2 are respectively provided with fixing seats 6 on their sides. The fixing seats 6 of the upper shell 1 and the fixing seats 6 of the lower shell 2 surround each other to form a fixing opening 7 for the support seat 41 to be inserted. The support seat 41 is inserted into the fixing opening 7 and is sealed with the fixing opening 7. The periphery of the upper shell 1 covers the periphery of the lower shell 2. The sealing ring 3 is continuously sealed between the periphery of the upper shell 1 and the periphery of the lower shell 2 along the periphery of the lower shell 2, and the sealing ring 3 is at least partially wrapped around the outside of the support seat 41.

[0027] By setting up an upper shell 1, a lower shell 2, and a frame 4, the support base 41 can pass through the fixing port 7 between the upper shell 1 and the lower shell 2, which is more conducive to waterproof sealing in the overall structure. In addition, the gap between the periphery of the upper shell 1 and the lower shell 2 is directly sealed by a continuous sealing ring 3, thus achieving all-round waterproofing. In particular, even the support base 41 has a sealing ring 3 partially wrapped around its outside. Therefore, whether it is the upper shell 1, the lower shell 2, or the wheel assembly 5, the sealing ring 3 blocks and seals them. More importantly, the support base 41 itself is also sealed with the fixing seat 6 of the upper shell 1 and the lower shell 2. In this way, this utility model can run at high speed in water, and high-pressure water is difficult to enter the upper shell 1 and the lower shell 2. The toy race car is not easily damaged by water. It is very suitable for racing tracks with both water and land environments, achieving stable amphibious use and a better play experience.

[0028] The wheel assembly 5 includes a wheel body and an axle 51. The axle 51 rotates via a motor and transmission components within the frame 4, which in turn drives the wheel body. Four wheels can be provided for maneuvering this toy race car. The support base 41 can be a bearing housing for the axle to pass through and rotate. The sealing ring 3 is made of rubber, but silicone can also be used. The shapes of the fixing base 6 and the fixing port 7 can be configured arbitrarily as needed; in this embodiment, a circular shape is preferred to facilitate sealing and centering during installation.

[0029] To enhance the sealing effect at the support base 41, a sealing ring 8 is provided around the outer periphery of the support base 41 in this embodiment. The sealing ring 8 is placed between the upper shell 1 and the lower shell 2 and is in a sealing fit with the upper shell 1 and the lower shell 2. In this way, the sealing ring 8 further increases the gap formed between the fixing port 7 and the support base 41. Secondly, the sealing ring 8 and the sealing ring 3 also form two sealing and waterproof lines, providing a double sealing effect. The sealing ring 8 can be made of rubber or silicone, or other elastic materials.

[0030] like Figure 1 , Figure 3As shown, to simplify the structure while improving the sealing effect, the sealing ring 3 in this embodiment is at least partially wrapped around the outside of the sealing ring 8, and the sealing ring 3 and the sealing ring 8 are tightly fitted together. The method of superimposing the sealing ring 3 and the sealing ring 8 is a special form of double sealing. Since the sealing ring 3 and the sealing ring 8 are superimposed in position, the space occupied by the lateral sealing is reduced. Furthermore, since the sealing ring 3 and the sealing gasket are usually easier to fit together and have elasticity, they interact with each other to provide elasticity, resulting in a better sealing effect.

[0031] like Figure 1 As shown, to better position the sealing ring 8 and prevent it from shifting due to vibration, the outer periphery of the support base 41 is provided with a mounting ring groove 411. The sealing ring 8 is fitted into and embedded in the mounting ring groove 411. During the high-speed operation of the toy race car, various components are prone to loosening due to vibration and impact. The mounting ring groove 411 facilitates the stable installation of the sealing ring 8.

[0032] like Figure 3 , Figure 6 As shown, furthermore, a reinforcing ring 81 protrudes from the side of the sealing ring 8. The thickness of the reinforcing ring 81 is less than the thickness of the sealing ring 8, and the reinforcing ring 81 is pressed against the groove wall of the mounting ring groove 411. After prolonged use and material aging, the sealing ring 8 is prone to irreversible deformation due to the compression from the upper shell 1 and the lower shell 2, leading to a decrease in sealing performance. In this example, the reinforcing ring 81 prevents the sealing ring 8 from deforming under pressure, maintaining its basic shape while retaining a certain elasticity, thus avoiding excessive deformation and resulting in excessive gap leakage. The thinner thickness of the reinforcing ring 81 also allows it to be squeezed between the mounting ring groove 411 and the sealing ring 8 under elastic pressure, maintaining elastic force and support for the sealing ring 8. Specifically, in one embodiment, the protrusion height of the reinforcing ring 81 gradually decreases from the outside to the inside, and the cross-section of the reinforcing ring 81 is conical. Thus, the reinforcing ring 81 cooperates with the groove wall of the mounting ring groove 411, ensuring that the sealing ring 8 is always centered within the mounting groove, effectively preventing displacement. Accordingly, as... Figure 1 , Figure 3 As shown, in this embodiment, the two groove walls of the mounting ring groove 411 are respectively set as inclined walls 9. The two inclined walls 9 are opposite to each other, so that the cross section of the mounting ring groove 411 forms an inverted cone shape that is wider on the outside and narrower on the inside. The inclined walls 9 are pressed against the reinforcing ring 81. The inclined walls 9 also have a centering function, which has a better centering adjustment effect on sealing rings 8 of any shape, so that the sealing ring 8 is better positioned in the mounting ring groove 411.

[0033] like Figure 1As shown, to enhance the firmness of the sealing ring 3, the lower shell 2 in this embodiment is provided with a positioning protrusion 21 on its periphery, and the upper shell 1 is provided with a positioning groove 11 on its periphery. The sealing ring 3 is pressed between the positioning groove 11 and the positioning protrusion 21. The positioning protrusion 21 can effectively compress the surface of the sealing ring 3, causing it to elastically deform and form an engagement, thereby making the sealing ring 3 firmly fixed and effectively resisting impact forces without displacement.

[0034] like Figure 2 , Figure 4 , Figure 5 As shown, a resilient button 10 extends from the frame 4, and the upper shell 1 has an opening 12 for the resilient button 10 to extend from. At least one annular retaining wall 13 is provided around the opening 12. Correspondingly, the frame 4 has at least one annular groove 42 for the annular retaining wall 13 to be inserted into in a sealing manner. In this embodiment, the resilient button 10 functions to start and stop the toy race car. Of course, a start / stop button or indicator light can also be configured as needed. In this example, the annular retaining wall 13 has two layers, corresponding to two annular grooves 42, achieving a two-layer sealing and waterproof performance. The resilient button 10 and the opening 12 elastically abut against each other for better sealing.

[0035] As a further improvement, the elastic button 10 includes a button head 101 and an elastic body 102. The elastic body 102 is in close contact with at least one of the annular baffle wall 13 and the inner wall of the upper shell 1 on the outer periphery of the opening 12. In the embodiment, the elastic body 102 is in close contact with both the annular baffle wall 13 and the inner wall of the upper shell 1 to effectively prevent water from entering through the opening 12. The opening 12 is funnel-shaped with a smaller outer side and a larger inner side so that the button head 101 has sufficient room to move within the opening 12 to prevent the button head 101 from getting stuck. This maximizes the prevention of water ingress and ensures the reset action of the button head 101.

[0036] The embodiments of this utility model are not limited thereto. Based on the above embodiments of this utility model, using conventional technical knowledge and common methods in the field, without departing from the basic technical idea of ​​this utility model and without conflict, the above preferred embodiments can be modified, replaced or combined in various other forms. All other embodiments obtained fall within the scope of protection of this utility model.
