Description

Technical Field

[0001] The utility model relates to the field of toys, in particular to a toy car with body parts capable of being quickly replaced. Background Art

[0002] Toy cars are generally composed of two independent bodies, the body and the shell. The reasons for designing them to be independent are, firstly, to facilitate mold production, and secondly, to facilitate the installation of wheels or drive components.

[0003] Most existing toy cars are designed to be electrically driven or remotely controlled, so drive components are installed inside the car body. Generally, the drive components include a motor, a rotating shaft, gears, a differential, etc. In some toy cars, the gears are centrally installed in a gear box, which is then fixed to the car body with screws, while other drive components, such as the motor, differential, main shaft, wheel axles, etc., are directly arranged in a large cavity in the car body. Finally, a cover is placed to secure all the drive components to the car body. Such a design means that when the car body parts need to be replaced, once the cover is removed, all the drive components inside will be accidentally scattered, which ultimately makes recovery difficult. Utility Model Content

[0010] Correspondingly, the cover plate includes a front plate cover, and the front plate cover is placed at the open mouth of the front cavity to ensure that the front differential can only rotate within the front cavity.

[0011] In some embodiments, the installation position of the rear end of the vehicle chassis is the rear cavity with the opening facing rearward, and the rear cavity is constructed to have the same shape as the front cavity and is symmetrically arranged front to back.

[0012] In some embodiments, the installation position in the middle of the vehicle chassis is a concave cavity with the opening facing upward; the cover plate includes a top plate cover, and the top plate cover is placed at the opening of the concave cavity.

[0013] Furthermore, a plurality of partitions are provided in the cavity to divide the cavity into a plurality of accommodating cavities for placing different driving components.

[0014] Furthermore, the driving components include a motor and a main shaft, and the multiple accommodating cavities include a strip-shaped shaft cavity located in the middle position of the concave cavity and extending in the front-to-back direction, and a motor cavity located on one side of the shaft cavity. The motor is placed in the motor cavity, the main shaft is placed in the shaft cavity, and the top plate cover is placed above the shaft cavity and above the corresponding motor shaft position of the motor cavity.

[0015] In some embodiments, the mounting position on the vehicle chassis includes a front cavity, a rear cavity, an axial cavity, and a motor cavity, wherein the axial cavity is constructed as a strip-shaped cavity extending in the front-to-back direction, and the front and rear ends of the axial cavity are respectively provided with through holes to connect with the front cavity and the rear cavity, and the side wall of the motor cavity corresponding to the position of the motor shaft is provided with the through hole to connect with the axial cavity.

[0016] The beneficial effects of the utility model are:

[0017] (1) Since there are at least two mounting positions on the vehicle chassis, and each mounting position has an opening, a cover plate is provided to connect with the mounting position to cover the opening, so each mounting position can hold one or two driving components.

[0047] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "match," "connect," "connect," and "install" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0048] The toy car with quickly replaceable body parts of the present invention will be described below with reference to the accompanying drawings.

[0049] The toy car described in the present invention can be an electric toy car for younger children to play with, a remote control toy car, or a remote control model car for older children (such as children over 12 years old).

[0050] like Figures 1 to 4 As shown, the utility model relates to a toy car with a body 102 component that can be quickly replaced, comprising a body 102 and a shell 101, wherein the shell 101 is detachably connected to the body 102, and is characterized in that the body 102 comprises a chassis 1 and a cover 2, wherein the chassis 1 is located at the bottom of the toy car, and at least two of the three positions of the front end 11, the middle part 12 and the rear end 13 of the chassis 1 are provided with mounting positions 3 for placing driving components for driving the toy car to travel. It can be understood that at least two mounting positions 3 are provided on the chassis 1, and these two mounting positions 3 can be respectively located at the front end 11 and the rear end 13 of the chassis 1, or respectively located at the front end 11 and the middle part 12 of the chassis 1, or respectively located at the middle part 12 and the rear end 13 of the chassis 1. It is further understood that the present invention does not limit the number of mounting positions 3 at each position. For example, two mounting positions 3 can be provided at the front end 11, and three or more mounting positions 3 can be provided at the middle portion 12. Alternatively, it is understood that there is one mounting position 3 at each position, but each mounting position 3 is further divided into multiple mounting cavities for the installation of drive components. The purpose of such a design is to allow the drive components to be installed separately on each mounting position 3, that is, one or two drive components are placed on each mounting position 3. At the same time, an opening is provided on the mounting position 3 to facilitate the placement or removal of the drive components. In order to achieve linkage between the drive components in different mounting positions 3, a through hole 30 is provided between two adjacent mounting positions 3 to enable connection and cooperation between the two adjacent drive components. The cover plate 2 is detachably connected to the opening of the mounting position 3 to fix the drive component in the mounting position 3. Therefore, each mounting position 3 can hold one or two driving components. When a driving component needs to be replaced, it is only necessary to open the cover 2 of the mounting position 3 where the driving component is located to take it out and replace it. This will not affect or cause other driving components to scatter out, so replacement is convenient and quick.

[0051] It can be understood that the detachable connection method between the cover 2 and the mounting position 3 of the present invention can be designed according to actual needs. For example, if the actual need is to allow players to easily disassemble and assemble, then the detachable connection method between the cover 2 and the mounting position 3 can be designed to be a connection method such as buckle connection and card connection that is convenient for bare-handed disassembly and assembly; for example, if the actual need is not to allow players to disassemble and assemble with their bare hands, but requires adults or players above the age of junior high school to use tools to disassemble and assemble, then the detachable connection method between the cover 2 and the mounting position 3 can be designed to be a connection method such as screw locking.

[0052] The drive components of the present invention are components of the vehicle body 102. It should be understood that the cover plate 2 of the present invention is also a component of the vehicle body 102 and can be replaced as needed. Therefore, the quickly replaceable components of the vehicle body 102 of the present invention include at least the drive components and the cover plate 2. Furthermore, the so-called quick replacement does not necessarily mean that components of the vehicle body 102 can be disassembled and assembled by hand. Rather, it means that when replacing components of the vehicle body 102, such as the drive components and the cover plate 2, there is no risk of all the internal drive components accidentally falling out once disassembled, as is the case with existing toy cars, which ultimately make recovery difficult or time-consuming. This allows for quick replacement.

[0053] In order to achieve a faster replacement effect and avoid affecting the driving effect of the wheels 43 when replacing the body 102 parts, the body 102 of the present invention also includes two wheel 43 frames 4. These two wheel 43 frames 4 are independently arranged with the body 102. Each wheel 43 frame 4 is connected to two left and right wheels 43. The two wheel 43 frames 4 are respectively connected to the front end 11 and the rear end 13 of the chassis 1, and the transmission is carried out through the transmission parts on the wheel 43 frames 4 and the driving components installed in the installation position 3. Specifically, after the wheel 43 frames 4 of the present invention are connected to the body 102, they will not block or obstruct any cover plate 2, that is, the cover plate 2 can be disassembled and assembled relative to the installation position 3 at any time when the wheel 43 frames 4 are connected to the chassis 1, and will not affect the wheel 43 frames 4. Therefore, when the body 102 parts such as the driving components are replaced, the performance of the wheel 43 components will not be affected. Figure 2 In the illustrated embodiment, each wheel carrier 43 is divided into a left wheel carrier 41 and a right wheel carrier 42. The left and right wheel carriers 41, 42 are symmetrically arranged and have identical structures. Therefore, only the left wheel carrier 41 will be further described. One end of the left wheel carrier 41 is connected to the left outer wall of the mounting position 3. In this embodiment, this connection is rotatable, but other connection methods, such as a fixed connection, are also possible. The other end of the left wheel carrier 41 is connected to the left wheel 43. The rotating wheel axle on the left wheel carrier 41 extends into the mounting position 3 to connect with the differential therein.

[0054] like Figure 3 、 Figure 5 and Figure 6 As shown, the chassis 1 of this embodiment includes mounting locations 3 at the front end 11 and at the middle 12. The mounting location 3 at the front end 11 is a front cavity 31 with its opening facing forward. This cavity 31 is located in the center of the front end 11 of the chassis 1. U-shaped openings are provided on either side of the cavity 31, allowing the rotating axles of the wheel carriers 43 to extend into the cavity 31. The drive components include a front differential 5, rotatably mounted within the cavity 31. The front differential 5 is configured to engage the rotating axles of the wheel carriers 43, thereby driving the wheels 43 mounted thereon. The corresponding cover 2 of this embodiment includes a front plate cover 21, which is positioned over the opening of the cavity 31, i.e., the front end 11 of the cavity 31, thereby preventing the front differential 5 from rotating within the cavity 31. The front plate cover 21 of this embodiment is secured to the cavity 31 by bolts 9. The mounting position 3 of the middle portion 12 of the chassis 1 of this embodiment is a concave cavity with an opening facing upward, and the corresponding cover plate 2 is a top plate cover 22, which is placed on the opening of the concave cavity. Figure 3 As shown, three partitions are provided in the concave cavity of this embodiment, thereby dividing the concave cavity into four accommodating cavities. One of the accommodating cavities is located in the middle of the concave cavity and extends in the front-to-back direction. The accommodating cavity is a rectangular cavity in the shape of a strip as a whole. The accommodating cavity is an axis cavity 32 for placing the rotating shaft; two large spaces are formed on both sides of the axis cavity 32, and the large space on one side is further divided into two accommodating cavities by the remaining partitions. One of the accommodating cavities is a motor 6 cavity 33 for placing the motor 6, and the remaining half of the accommodating cavity is used to place the circuit board; and the large space on the other side forms an accommodating cavity as a whole, for placing the power supply. It can be understood that the mounting position 3 of the middle part 12 can also be divided into two, three, or more accommodating cavities as needed.

[0055] like Figure 5 and Figure 6As shown, correspondingly, the driving parts of this embodiment include a motor 6 and a main shaft 7, wherein the main shaft 7 includes a rod body 71 and gears connected to both ends of the rod body 71, and the cavities at both ends of the shaft cavity 32 are slightly larger and narrower in the middle, and the cavities at both ends can accommodate the gears at both ends of the main shaft 7; the motor 6 is placed in the motor 6 cavity 33, and the motor shaft 61 of the motor 6 faces one end of the main shaft 7 that is closer. In order to achieve that the gear on the motor shaft 61 can mesh with the gear on the main shaft 7, a through hole 30 is opened on the side wall of the motor 6 cavity 33 corresponding to the position of the motor shaft 61 and facing the shaft cavity 32, so that the motor 6 cavity 33 and The shaft cavity 32 is connected, and the gear on the motor shaft 61 is engaged with the gear on the main shaft 7; the top plate cover 22 of this embodiment is in the shape of a 7, and its long end is consistent with the length of the shaft cavity 32 and is covered on the upper end of the shaft cavity 32 to cover the open mouth. The short end of the top plate cover 22 is facing the motor shaft 61 position of the motor 6, and is covered on the upper end of the motor 6 cavity 33 corresponding to the motor shaft 61 position, and presses the front end 11 part of the motor 6 body to fix the motor 6, and at the same time constrains the gear of the motor shaft 61 to rotate internally and will not disengage. The top cover plate 2 is also locked and fixed to the vehicle chassis 1 by bolts 9. Similarly, the front end 11 of the shaft cavity 32 is adjacent to the front cavity 31, that is, the front wall of the shaft cavity 32 and the rear wall of the front cavity 31 share a common wall surface, on which a through hole 30 is opened, so that the shaft cavity 32 and the front cavity 31 are communicated. In addition to being provided with a gear that meshes with the gear of the motor shaft 61 at the end of the main shaft 7 facing the front end 11 of this embodiment, there is also a bevel tooth 72, which passes through the through hole 30 and extends into the front cavity 31 to mesh with the differential in the front cavity 31.

[0056] like Figure 4-Figure 6 As shown, in addition to the front cavity 31, the shaft cavity 32, and the motor 6 cavity 33, the mounting position 3 of this embodiment also includes a mounting position 3 located at the rear end 13 of the chassis 1. This mounting position 3 is a rear cavity 34 with its opening facing rearward. In this embodiment, the rear cavity 34 is constructed to be consistent in shape with the front cavity 31 and is symmetrically arranged with the front cavity 31, so it will not be described in detail. The rear cavity 34 is also used to house the rear differential 8, which is matingly connected to the axle of the wheel frame 43 located at the rear end 13. The cover plate 2 also includes a rear plate cover 23, which is connected to the rear cavity 34 to cover the opening of the rear cavity 34. The connection method is also to lock and secure it with bolts 9. Correspondingly, a through hole 30 is also opened between the rear end 13 of the shaft cavity 32 and the rear cavity 34 to achieve mutual communication. At the same time, the rear end 13 of the main shaft 7 is also provided with a bevel tooth 72 which extends into the rear cavity 34 and engages with the differential in the rear cavity 34.
