TECHNICAL FIELD

[0001] The utility model relates to the technical field of sled car, concretely relates to a sled car control device. BACKGROUND

[0002] The control device of the sled car mainly includes a direction column rotatably connected to the frame and a handle tube fixedly connected to the direction column, and the handle tube drives the direction column to rotate, thereby driving the sled plate or the front wheel of the sled connected to the direction column to change direction.

[0003] On a conventional sled car, a handle sleeve is sleeved on the handle tube, and a throttle control and a brake control are also installed on the handle tube, such as an oil door operator for controlling the throttle beside the right handle sleeve and a brake for controlling the vehicle brake beside the left handle sleeve.

[0004] However, for the sled car, the hands are prone to be frozen stiff due to driving in cold wind, so a handle sleeve with a heater is needed. In addition, there is a problem that the connection stability of the existing handle tube and direction column is not enough, such as the child snowmobile steering device with publication number CN215284951U. This connection mode of the direction column and the handle tube is not a problem for the child snowmobile, but if it is used for adult sled cars with high load requirements, the connection stability of the direction column and the handle tube is lacking. A published US patent US20240083545A1 discloses a steering system for a snowmobile, which has a clamping seat welded between the direction column and the handle tube to improve the connection stability of the direction column and the handle tube. However, welding the direction increases the process cost. Another US patent US20240083490A1 adjustable handlebar vertical pipe realizes the simplicity of the installation process on the basis of ensuring the connection stability of the direction column and the handle tube through the assembly structure of multiple parts. However, this structure has the problems of too many parts and complicated assembly. UTILITY MODEL CONTENTS

[0017] Since the snowmobile is used in a cold environment, and the power supply of the snowmobile is usually a storage battery, the storage battery is prone to power supply in a cold environment, and if the handle sleeve heating is started when the engine is not started or at a low speed, the power consumption of the heating is high, and the power of the storage battery will be easily consumed, and the storage battery will only be charged stably when the engine speed reaches a certain value, if the power of the storage battery is consumed too fast and the charging cannot be supplemented in time, other electric components cannot be normally used. The ECU controls the heating relay to ensure that the handle sleeve heating is only used when the engine stably supplies power to the storage battery, and ensures that the handle sleeve heating does not affect other functions.

[0018] Preferably, as an improvement, the heating relay is connected with a heating fuse between the general switch, to ensure that the current is cut off in time when the current is overloaded, to prevent safety hazards, and to ensure that the connection of the general switch and other circuits is not affected, and the independence of the circuit is ensured.
