[0029] Please refer to Figures 1 to 4 , shows a toy car that can fix building blocks provided by the first embodiment, including a vehicle frame 100, a first connecting portion 110 is provided on one side of the vehicle frame 100, and a second connecting portion 120 is provided on the other side of the vehicle frame 100 that is detachably connected to the first connecting portion 110 of another vehicle frame 100. It can be understood that the detachable cooperation between the first connecting portion 110 and the second connecting portion 120 enables the toy car to adjust the number of vehicle frames 100 connected together according to the actual needs of the players, thereby making the overall length of the toy car adjustable, with high game freedom and high playability.

[0030] In this embodiment, the first connection part 110 is a clamping opening provided on the side wall of the vehicle bottom frame 100, and the second connection part 120 is a connection column protruding on the side wall of the vehicle bottom frame 100. The outer end of the connection column extends outwardly to form a flange 121. The column body of the connection column can be inserted into the clamping opening and clamped in another vehicle bottom frame 100 through the flange 121. It can be understood that setting the first connection part 110 as a clamping opening structure and setting the second connection part 120 as a column structure with a flange 121 can achieve seamless fixation between two vehicle bottom frames 100 on the one hand, and improve the aesthetics. On the other hand, the column structure with a flange 121 can simulate the shape of the front headlights of the vehicle, further improving the aesthetics. In other embodiments of the utility model, the first connection part 110 and the second connection part 120 can be adjusted to other detachable structure types, such as a through hole and a protruding column protruding from the side wall of the vehicle bottom frame 100, and two sockets protruding from the side wall of the vehicle bottom frame 100 that can be connected by a pin, etc.

[0031] The top surface of the vehicle bottom frame 100 is at least partially convex or concave to form a connecting cavity 130, and the plane where the endpoints of each cavity wall in the connecting cavity 130 are located is projected on the top surface in a rectangular shape. In other words, the shape of each cavity wall of the connecting cavity 130 can be set to be flat, curved, corrugated, etc., but the planes where the endpoints of each cavity wall are located intersect to form a rectangular cavity. The width of the rectangle is na centimeters, and the ratio of the length and width of the rectangle is N. Among them, the range of a is greater than or equal to 1.5 and less than or equal to 2, for example, the value of a can be 1.5, 1.6, 1.7, 1.8, 1.9 or 2, etc., and n and N are both positive integers greater than or equal to 1, for example, they can be 1, 2, 3, 4, 5, etc. It can be understood that the depth of the connecting cavity 130 is h cm, where the value of h is smaller than the value of a, and the numerical ratio between the two is greater than or equal to 0.15 and less than or equal to 0.25. For example, the ratio between the two can be 0.15, 0.18, 0.2, 0.22, 0.24, 0.25, etc.

[0032] It is understandable that the above setting can limit the width of the rectangle to a specific numerical range, and the length of the rectangle can also be limited to an integer multiple of its width, so that the connecting cavity 130 can be adapted to at least one number of square building blocks commonly seen on the market. During assembly and use, a plurality of square building blocks that can form the cavity bottom area of ​​the connecting cavity 130 are placed in the connecting cavity 130, and a plurality of square building blocks can be fixed on the vehicle chassis 100, which has a simple structure and convenient operation, and there is no risk of losing accessories, and it is highly practical. Moreover, the above setting can also limit the ratio of the depth of the connecting cavity 130 to the side length of the square building block to a specific numerical range, which is used to play the role of fixing and holding the square building block without blocking the surface pattern of the square building block, so that players can combine different patterns on the toy car to change the appearance of the toy car, which can further improve the playability and fun of the toy car.

[0033] In this embodiment, two opposite sides of the top surface of the vehicle bottom frame 100 are raised to form a first baffle 131, and the other two opposite sides of the vehicle bottom frame 100 are raised to the top surface to form a second baffle 132, and a connecting cavity 130 is defined between the second baffle 132 and the first baffle 131.

It is understood that the first axis frame 12 and the second axis frame 22 are located at different positions on the same axis, and the first axis frame 12 and the second axis frame 22 are rotatably connected with the rotating shaft 210 to improve the rotation stability of the rotating shaft 210 and make the structure more compact. In other embodiments of the utility model, the first axis frame 12 and the second axis frame 22 can be arranged correspondingly, and at this time, the first axis frame 12 and the second axis frame 22 are spliced ​​to form a connecting hole for the rotating shaft 210 to rotate through. The number of the first axis frame 12 and the second axis frame 22 is the same as the number of the rotating shaft 210 or twice the number of the rotating shaft 210.

[0037] In this embodiment, the inner wall of the mounting groove 11 is provided with two first plug-in posts 13 at intervals along its extension direction, and the inner side wall of the second housing 20 is provided with a second plug-in post 23 corresponding to the first plug-in post 13, wherein the first plug-in post 13 and the second plug-in post 23 can be plugged and fixedly connected to play a role in quickly assembling the vehicle chassis 100.
