Description

Technical Field

[0001] The utility model relates to the technical field of CAN bus protocol conversion, in particular to a CAN bus protocol conversion device suitable for shared electric vehicles. Background Art

[0002] CAN bus protocol converter is a product that converts the communication between CAN bus devices into different protocols. CAN bus is widely used, covering industrial control, automotive electronics, large medical equipment, servo motors, scientific research and other fields. In order to facilitate the management and control of shared bicycles, it is applied to shared bicycles. The CAN bus protocol converter can realize the sending, receiving, transmission and interaction of shared bicycle data.

[0003] When in use, since shared bicycles are always outdoors, they will be affected by natural factors such as wind, water and rain, which will affect the normal use of the converter. Therefore, the converter needs to be inspected and maintained regularly to ensure its normal operation and extend its service life. The existing converters are generally installed in the vehicle body, which is not convenient for disassembly and maintenance. Therefore, further improvement can be made. Utility Model Content

[0005] As an optimization, the sealing grooves are arranged in circles around the inner wall of the chamber, and the rubber sealing sleeves are arranged with three circles corresponding to the sealing grooves, and each circle of rubber sealing sleeves is embedded in each circle of sealing grooves. The three circles of rubber sealing sleeves are embedded in the three circles of sealing grooves in turn, forming a multiple sealing effect to prevent rainwater from entering the chamber and affecting the equipment.

[0006] As an optimization, guide plates are fixedly installed on both sides of the bottom of the drawer box, a connecting head for connecting the converter is provided inside the drawer box, convex plates are fixedly installed in the middle of both sides of the drawer box, guide grooves are provided on the inner wall of the chamber corresponding to the guide plates, and the guide plates are slidably connected in the guide grooves, and the guide plates slide along the inside of the guide grooves to play a guiding and limiting role, so that the drawer box can move in and out of the chamber horizontally.

[0007] As an optimization, an embedded groove is provided on the outer surface of the blocking plate, and a pull frame is rotatably hinged inside the embedded groove. By pulling the pull frame out of the embedded groove and flipping it to be vertical with the blocking plate, it can be used as a tool to assist in pulling out the blocking plate, making it convenient to pull the drawer box out.

[0012] 1. The CAN bus protocol conversion device suitable for shared electric vehicles has an embedded pull frame. When in use, the pull frame can be pulled out to facilitate pulling the drawer box in and out, thereby facilitating the maintenance of the converter. A series of rubber sealing sleeves are embedded in the sealing groove in turn to form multiple sealing rings, which further improve the sealing effect and prevent external rainwater from entering the chamber and affecting the equipment.

[0013] 2. The CAN bus protocol conversion device suitable for shared electric vehicles is pushed into the chamber through the drawer box, which will drive the wheel to rotate through the convex plate. At the same time, the friction ring will increase the friction in contact with the convex plate, which will drive the screw to rotate, so it will drive the support plates on both sides to slide downward synchronously, and then drive the pressure plate to move downward, so that the rubber pad is squeezed on the top of the converter, thereby positioning the converter and preventing the converter from falling off when riding a shared bicycle.
