DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following combines the drawings and embodiments to describe the present utility model in detail.

[0018] As Figure 1-2As shown in the figure, the utility model provides a temperature warning device for a two-wheeled electric vehicle battery pack, which includes two symmetrically installed brackets 1 on the left and right. A fiber optic cable 2 for temperature measurement and a transverse movement mechanism 3 are installed on the two brackets 1. The output end of the transverse movement mechanism 3 is connected to the fiber optic cable 2 to drive it to move in a horizontal straight line.

[0019] The bracket 1 is the main support structure and is fixed to the frame of the two-wheeled electric vehicle for parking through bolts to ensure the stability of the entire device. Specifically, the bracket 1 is in an L shape, which is convenient for installation and fixation. It is spliced by square pipes. There are installation holes at the bottom of the bracket 1, which are convenient for fixed connection with the frame of the two-wheeled electric vehicle. Further, a reinforcing rib is installed at the corner of the bracket 1 to increase its overall rigidity and stability.

[0020] The fiber optic cable 2 is a flexible and durable temperature measurement element, and multiple high-precision temperature sensors are embedded inside. The fiber optic cable 2 is connected to the transverse movement mechanism 3 through a connecting plate 34 and reaches the designated position as the transverse movement mechanism 3 moves, to perform real-time temperature measurement on the battery packs of the two-wheeled electric vehicle in each area. The temperature sensors distributed in the fiber optic cable 2 can sense and collect the temperature data of each point of the battery pack in real time. These data are transmitted to the control system through the wires or wirelessly inside the fiber optic cable 2. Once abnormal temperature is detected, the warning mechanism is immediately triggered to remind the user to take corresponding measures.

[0021] The transverse movement mechanism 3 includes a driving component 31, a supporting component 32, a position sensing component 33 and a connecting plate 34. The output end of the driving component 31 is connected to one end of the connecting plate 34, the movable end of the supporting component 32 is connected to the other end of the connecting plate 34, and the position sensing component 33 is installed at one end of the supporting component 32.

[0022] The driving component 31 includes a motor 311, a main sprocket 312, a driven sprocket 313, a chain 314, a synchronous rod 315, a belt pulley 316 and a synchronous belt 317. The motor 311 is installed on the bracket 1 at any one end. The motor 311 is specifically selected as a servo motor 311 to ensure the accuracy of its linear motion. The main sprocket 312 is installed at the output end of the motor 311 and rotates synchronously with the motor 311.

[0023] The synchronous rod 315 is a long round rod, and its length spans the distance between the two brackets 1. The two ends are rotatably installed on the two brackets 1. Further, supporting seats for supporting the rotation of the synchronous rod 315 are respectively installed on the two brackets 1, and bearings are installed inside the supporting seats. The outer diameter of the synchronous rod 315 matches the inner diameter of the bearing, making the rotation of the synchronous rod 315 smoother and more reliable.

[0024] The driven sprocket 313 is fixedly installed at one end of the synchronizing rod 315 close to the motor 311. The main sprocket 312 is connected to the driven sprocket 313 by a chain 314. The main sprocket 312 drives the driven sprocket 313 on the synchronizing rod 315 to rotate through the chain 314, and the driven sprocket 313 further drives the synchronizing rod 315 to rotate.

[0025] On each of the two brackets 1, a set of pulleys 316 are rotatably installed, and one of the set of pulleys 316 is installed on the synchronizing rod 315. When the set of pulleys 316 are installed, they should be kept in the same straight line. The timing belt 317 is sleeved outside each set of pulleys 316 to maintain the synchronous transmission of the two pulleys 316.

[0026] A tensioning seat 319 for tensioning the timing belt 317 is installed on the bracket 1. One of the pulleys 316 (i.e., the pulley 316 away from the synchronizing rod 315) is rotatably installed on the tensioning seat 319. By adjusting the position of the tensioning seat 319, the tightness of the timing belt 317 can be changed to ensure that the timing belt 317 always maintains an appropriate tightness and improve the transmission efficiency. Specifically, an adjustment chute is provided on the bottom surface of the tensioning seat 319, and an adjustment bolt is installed on the side surface of the tensioning seat 319. The adjustment bolt abuts against the side surface of the bracket 1, and the tensioning of the timing belt 317 is adjusted through the adjustment bolt.

[0027] The T-shaped connecting plate 34 is installed at one end of the top of the timing belt 317. Specifically, a meshing plate is installed on the timing belt 317, which can mesh with the tooth shape of the timing belt 317, and the meshing plate is fixedly installed on the connecting plate 34. In this way, when the synchronizing rod 315 rotates, the pulleys 316 installed at its left and right ends can rotate synchronously and drive the timing belt 317 to move, and finally drive the optical cable 2 to perform a linear translation. The optical cable 2 is installed at the opposite end positions of the left and right ends of the connecting plate 34.

[0028] The support assembly 32 is installed on each bracket 1. The support assembly 32 includes a guide rail 321 and a slider 322. The guide rail 321 is installed on the top of the bracket 1, and the guide rail 321 is parallel to the timing belt 317. The slider 322 is slidably installed on the guide rail 321, and the connecting plate 34 is fixedly installed on the slider 322. The support assembly 32 is mainly used to support the linear movement of the connecting plate 34 to ensure the smoothness and accuracy of the movement of the optical cable 2.

[0029] A position sensing component 33 is installed on one of the brackets 1. The position sensing component 33 includes photoelectric sensors 331 installed at both ends in the length direction of the support component 32 and a light blocking piece 332 installed at one end of the connecting plate 34. The photoelectric sensors 331 are used to detect the end positions of the movement of the connecting plate 34 to ensure the safety of the movement. The photoelectric sensors 331 are installed at the two end positions of the guide rail 321 and are fixed by the Z-shaped plates on the outer edge. The light blocking piece 332 is fixed at one end of the connecting plate 34 and blocks or exposes the photoelectric sensors 331 as the connecting plate 34 moves, thereby triggering position signals.

[0030] To improve the stability and reliability of the device, a plurality of first support members 4 for supporting the optical cable 2 are also installed at equal intervals between the two brackets 1 to prevent it from sagging or deforming due to gravity. Rectangular sliding grooves are provided on the first support members 4 for the optical cable 2 to slide thereon for sliding support.

[0031] In addition, a plurality of second support members 318 for supporting the rotation of the synchronizing rod 315 are installed at equal intervals on the synchronizing rod 315 to enhance the rigidity and stability of the synchronizing rod 315 and prevent deformation due to long-term rotation. The second support members 318 are fixedly connected to the external vehicle frame and bearings are also installed thereon to better support the rotation of the synchronizing rod 315.

[0032] During the charging process after the two-wheeled electric vehicle is parked, the transverse movement mechanism 3 automatically drives the optical cable 2 to perform transverse scanning according to a preset program to monitor the temperature conditions of the battery packs in each area in real time, or it can also move to a fixed position for monitoring. The control system receives the data from the temperature sensors in the optical cable 2 and processes and analyzes it. Once an abnormal temperature condition is detected, the warning mechanism is immediately triggered to remind the user.

[0033] In summary, the two-wheeled electric vehicle battery pack temperature warning device provided by the present utility model has the advantages of comprehensive coverage, accurate temperature measurement, intelligent warning, and stable structure, can significantly improve the safety of the use of two-wheeled electric vehicles, and has a wide application prospect.

[0034] The above is only the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
