[0002] Remote-controlled toy cars are educational toys whose movements can be controlled by a control device, and are greatly enjoyed by children and adults alike. The toy car's shell is typically detachably connected to the toy car's main body via a hinged lock. This lock utilizes a dual-locking mechanism: by pulling the lock upward, the hook-shaped locking structure of the lock connects to the toy car's main body. Then, by toggling a switch on the lock, the other locking structure engages the toy car's main body or shell, thereby locking the lock as a whole.

[0003] However, when the remote control toy car is actually used, the fixed lock on the market may loosen the switch due to road bumps and other conditions, resulting in unlocking, which results in a poor user experience. Utility Model Content

[0024] The present application provides a toy car shell fixing lock, including a main body and a switch member movably arranged on the main body, the main body including an unlocking part and a first locking part, the switch member is rotatably arranged on the upper side of the unlocking part, and the lower side of the unlocking part is provided with a first locking member connected to the switch member and rotating synchronously, the switch member is provided with a retractable second locking member protruding toward the unlocking part, and the unlocking part is provided with a locking hole that cooperates with the second locking member for positioning.

[0025] Implementation example Figures 1-2 As shown, a toy car shell fixing lock includes a main body mounted on the toy car shell. The main body includes an unlocking portion 1 and a first locking portion 2 extending from one side of the unlocking portion 1. The first locking portion 2 is a hook-shaped structure and is hingedly connected to the toy car shell. When locked, the hook-shaped first locking portion 2 engages with the toy car body to secure the toy car shell to the vehicle body. To unlock, the unlocking portion 1 is pulled upward, causing the hook-shaped first locking portion 2 to rotate downward, disengaging the hooked locking portion 2 from the toy car body, thereby unlocking the toy car shell.

[0026] Furthermore, a rotatable switch member 3 is disposed on the upper side of the unlocking portion 1. This switch member 3 includes a rotating shaft portion 3.1 and a switch member 3.2 that rotates about the rotating shaft portion 3.1. A first locking member 4 is disposed on the lower side of the unlocking portion 1, coaxially connected to the rotating shaft portion 3.1 of the switch member 3 and rotating synchronously with it. A second locking member 5 is provided on the switch member 3.2, protruding toward the unlocking portion 1. The unlocking portion 1 is provided with a locking hole 1.1 that cooperates with the second locking member 5.

[0027] Specifically, the switch portion 3.2 is provided with a movable hole 3.2.1, and the second locking member 5 is accommodated in the movable hole 3.2.1 and can perform telescopic movement in the movable hole 3.2.1.

[0028] Specifically, the second locking member 5 is a rod- or column-shaped structure that passes through the movable hole 3.2.1. A lifting portion 6 is connected to the side of the movable hole 3.2.1 away from the locking hole 1.1, which facilitates upward pulling of the second locking member 5. Pulling the lifting portion 6 upward causes the second locking member 5 to disengage from the locking hole 1.1. The second locking member 5 is provided with a locking end 5.1 and a first limiting portion 5.2 at one end near the locking hole 1.1. The locking end 5.1 mates with and is receivable within the locking hole 1.1. The first limiting portion 5.2 protrudes from the circumference of the second locking member 5 and serves to limit the depth to which the locking end 5.1 can be inserted into the locking hole 1.1.

[0029] Specifically, the opening diameter of the movable hole 3.2.1 near the locking hole 1.1 matches the first stopper 5.2, allowing the first stopper 5.2 to be pulled into the movable hole 3.2.1. The opening diameter of the movable hole 3.2.1 away from the locking hole 1.1 matches the second locking member 5 and is smaller than the first stopper 5.2, preventing the second locking member 5 from falling out of the movable hole 3.2.1.

[0030] Specifically, a return spring 7 is sleeved on the second locking member 5 to make it have a return tendency after retraction. The return spring 7 is accommodated in the movable hole 3.2.1. When the second locking member 5 is pulled upward, the return spring 7 can abut against the first limit portion 5.2.

[0031] Specifically, the first locking member 4 is provided with second locking portions 4.1 extending to both sides in the circumferential direction. The second locking portion 4.1 is driven to rotate by the switch member 3, thereby realizing the cooperation and locking of the second locking portion 4.1 with the toy car body or shell.

[0032] Furthermore, the unlocking portion 1 is provided with a second limiting portion 1.2 distributed around the rotating shaft portion 3.1 for limiting the rotation range of the switch member 3. The second limiting portion 1.2 is respectively set at a position where the switch member 3 can only drive the second locking member 5 to rotate 90°, thereby limiting the rotation range of the switch member 3 to 90°.

[0033] Specifically, the second limiting portion 1.2 is a raised limiting column.

[0034] Working Principle: This embodiment is a housing fixing lock for remote-controlled toy vehicles, the main body of which is hingedly connected to the toy vehicle housing. During use, the unlocking portion 1 is pulled upward, causing the first locking portion 2 to clear the connection portion on the vehicle body that mates with the first locking portion 2. After the vehicle body is installed on the vehicle, the unlocking portion 1 is reset. The first locking portion 2 now engages with the vehicle body, achieving a fixed connection between the two. The switch member 3 disposed on the unlocking portion 1 is then rotated, which drives the first locking member 4 at the lower end of the unlocking portion 1 to rotate until the switch member 3 is locked in place with the locking hole 1.1. At this point, the first locking member 4 engages with the abutment portion inside the vehicle body or the vehicle body, preventing the unlocking portion 1 from being pulled upward to unlock.

[0035] When unlocking, the lifting portion 6 is pulled upward to disengage the second locking member 5 from the locking hole 1 . 1 . At this time, the switch member 3 can drive the first locking member 4 to rotate again, thereby unlocking the unlocking portion 1 .
