Description

Technical Field

[0001] This utility model relates to the field of monitoring technology for drive motors of new energy trailers, and in particular to a fault early warning and monitoring device for drive motors of new energy trailers. Background Technology

[0002] The drive motor of a new energy trailer is the core power component of the new energy trailer. It converts electrical energy into mechanical energy to drive the trailer. During the operation of the new energy trailer, the drive motor is in a high-load state for a long time, and the stability of its working performance directly affects the driving safety and efficiency of the trailer.

[0003] The function of a fault early warning and monitoring device is to monitor the operating status of the drive motor in real time and issue an early warning in time before the motor fails, so that maintenance personnel can take measures to avoid the fault from escalating and causing more serious consequences. Traditional fault early warning and monitoring devices mostly rely on electronic sensors to obtain motor operating parameters. However, in some special environments, electronic sensors may be affected by factors such as electromagnetic interference, humidity, and high temperature, resulting in inaccurate monitoring data or even failure.

[0004] The existing fault warning and monitoring device for drive motors of new energy trailers has the following shortcomings:

[0005] Traditional devices have complex connection structures with drive motors, requiring tools and multiple steps for installation and disassembly. This not only increases the time and cost of installation and maintenance but also makes it difficult to quickly replace equipment in emergencies. In addition, the heat dissipation structure of existing devices is simple, often using simple ventilation holes and fans for cooling. This results in low heat dissipation efficiency and cannot effectively prevent dust from entering the equipment, causing electronic components to degrade in performance or even be damaged due to high temperature and dust accumulation. Utility Model Content

[0006] This utility model proposes a fault early warning and monitoring device for the drive motor of a new energy trailer. Through an innovative design of a quick installation structure and a high-efficiency heat dissipation and dustproof structure, the device improves the convenience and reliability of use, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a fault early warning and monitoring device for a new energy trailer drive motor, comprising a motor body, a connecting seat fixedly connected to the top left side of the motor body, a monitoring device body disposed on the top of the connecting seat, the monitoring device body being electrically connected to the motor body via wires, fixing components disposed on both the front and rear sides of the connecting seat, a heat dissipation component fixedly installed on the top of the monitoring device body, and fixing slots provided on both the front and rear sides of the monitoring device body.

[0008] The fixing assembly includes a sliding push plate. A sliding clamping plate is fixedly connected to the top of the sliding push plate near the connecting seat. The sliding clamping plate is slidably inserted into the inner surface of the fixing slot. A sliding groove is formed inside the sliding clamping plate. A transverse T-shaped push plate is slidably connected inside the sliding groove. Three clamping springs are fixedly connected to the side of the transverse T-shaped push plate near the sliding push plate. The end of the clamping spring away from the transverse T-shaped push plate is fixedly connected to the inner wall of the sliding groove. The side of the transverse T-shaped push plate away from the sliding push plate extends to the outside of the sliding clamping plate and is fixedly connected to a pressing sleeve plate. Vertical top plates are slidably inserted into the upper and lower sides of the inner surface of the pressing sleeve plate. Push plates are movably connected to the left and right sides of the vertical top plates opposite to the sliding clamping plate.

[0009] Preferably, the connector has two insertion holes on both the front and rear sides, and threaded holes are provided in the middle of both the front and rear sides.

[0010] Preferably, the sliding push plate has sliding guide rods fixedly connected to both the left and right sides of its bottom side near the connecting seat, and the outer surface of the sliding guide rods is slidably connected to the inner surface of the insertion hole.

[0011] Preferably, a threaded post is rotatably connected to the bottom center of the sliding push plate near the connecting seat. The outer surface of the threaded post is threadedly connected to the inner surface of the threaded hole. The end of the threaded post away from the threaded hole passes through the sliding push plate and is fixedly connected to a knob.

[0012] Preferably, the heat dissipation assembly includes a heat dissipation frame, which is disposed on the top of the monitoring device body. Two connecting lugs are fixedly connected to the left and right sides of the outer surface of the heat dissipation frame, and the connecting lugs are fixed to the top of the monitoring device body by screws.

[0013] Preferably, the heat sink has a through-type heat dissipation groove inside, and dust filters are fixedly connected to both the front and rear sides of the inner surface of the through-type heat dissipation groove.

[0014] Preferably, the heat sink has an annular cooling groove in the middle, and the front and rear ends of the annular cooling groove extend to the front and rear sides of the monitoring device body, respectively.

[0015] Preferably, a plurality of metal heat-conducting plates are fixedly connected in a ring array on the inner surface of the annular cooling groove. Flow grooves are provided on both sides of each metal heat-conducting plate, and the two flow grooves are respectively connected to the interior of the U-shaped heat dissipation groove and the annular cooling groove.

[0016] Preferably, a bidirectional motor is fixedly connected to both the front and rear sides of the inner wall of the U-shaped heat dissipation groove, and a heat dissipation fan is fixedly connected to one end of the output shaft of the bidirectional motor.

[0017] Preferably, the other end output shaft of the bidirectional motor extends into the interior of the annular cooling tank and is fixedly connected to a guide fan.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. In this utility model, when the monitoring equipment body needs to be installed, it is placed on the connecting seat. By rotating the knob, the threaded column is rotated in the threaded hole. Due to the sliding restriction of the sliding guide rod in the insertion hole, the sliding push plate slides along the front and back direction of the connecting seat, pushing the sliding card plate into the fixed slot, thus initially fixing the monitoring equipment body. As the sliding card plate continues to be inserted, the compression sleeve plate is first squeezed by the inner wall of the fixed slot, causing the transverse T-shaped push plate to slide in the sliding groove and compress the top spring. The sliding card plate and the compression sleeve plate gradually approach each other, and the push plate pushes the vertical top plate to press against the upper and lower sides of the fixed slot, thus achieving secondary reinforcement of the monitoring equipment body. This fixing method is simple to operate, and installation can be completed by simply rotating the knob, which greatly shortens the installation time and improves work efficiency. In addition, the pressing effect of the vertical top plate makes the connection between the monitoring equipment body and the connecting seat more stable, avoiding inaccurate monitoring data caused by loosening.

[0020] 2. In this utility model, when heat dissipation of the monitoring device body is required, the bidirectional motor is started, driving the guide fan and the exhaust fan to rotate simultaneously. The rotation of the guide fan causes the hot air inside the monitoring device body to flow in the annular cooling groove. The hot air passes through the flow groove on one side of the metal heat-conducting plate and transfers heat to the U-shaped exhaust groove through the metal heat-conducting plate. At the same time, the rotation of the exhaust fan drives the external cold air to flow in the U-shaped exhaust groove, carrying away the heat transferred from the metal heat-conducting plate, achieving rapid heat dissipation. This heat dissipation method, through the design of the annular cooling groove and the U-shaped exhaust groove, forms an efficient airflow channel, greatly improving heat dissipation efficiency. The setting of the metal heat-conducting plate increases the heat dissipation area, further improving the heat dissipation effect. At the same time, the dust filter in the U-shaped exhaust groove can effectively prevent dust from entering the device, avoiding electronic component failures caused by dust accumulation and extending the service life of the device.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: it includes a motor body 1, a connecting seat 2 fixedly connected to the top left side of the motor body 1, a monitoring device body 3 disposed on the top of the connecting seat 2, the monitoring device body 3 being electrically connected to the motor body 1 via wires, fixing components 4 disposed on both the front and rear sides of the connecting seat 2, a heat dissipation component 5 fixedly installed on the top of the monitoring device body 3, and fixing slots 31 opened on both the front and rear sides of the monitoring device body 3, the fixing component 4 including a sliding push plate 41, a sliding plate 45 fixedly connected to the top of the side of the sliding push plate 41 near the connecting seat 2, the sliding plate 45 being slidably inserted into the inner surface of the fixing slot 31, a sliding groove opened inside the sliding plate 45, a transverse T-shaped push plate 46 slidably connected inside the sliding groove, three clamping springs 47 fixedly connected to the side of the transverse T-shaped push plate 46 near the sliding push plate 41, the end of the clamping spring 47 away from the transverse T-shaped push plate 46 being connected to the sliding plate 41. The inner wall of the groove is fixedly connected. The side of the transverse T-shaped push plate 46 away from the sliding push plate 41 extends to the outside of the sliding clamping plate 45 and is fixedly connected to the extrusion sleeve plate 48. The upper and lower sides of the inner surface of the extrusion sleeve plate 48 are slidably inserted with vertical top plates 410. The left and right sides of the opposite surface of the vertical top plate 410 and the sliding clamping plate 45 are movably connected with push plates 49. The front and rear sides of the connecting seat 2 are provided with two insertion holes 21. The middle of the front and rear sides of the connecting seat 2 is provided with threaded holes 22. The bottom of the sliding push plate 41 near the connecting seat 2 is fixedly connected with sliding guide rods 42 on both sides. The outer surface of the sliding guide rods 42 is slidably connected to the inner surface of the insertion holes 21. The bottom center of the sliding push plate 41 near the connecting seat 2 is rotatably connected with a threaded column 43. The outer surface of the threaded column 43 is threadedly connected to the inner surface of the threaded hole 22. The end of the threaded column 43 away from the threaded hole 22 passes through the sliding push plate 41 and is fixedly connected with a knob 44.

[0030] The effect achieved by the entire embodiment 1 is as follows: When it is necessary to install the monitoring device body 3, the monitoring device body 3 is first placed on the connecting seat 2, so that the fixing slots 31 on the front and rear sides of the monitoring device body 3 are aligned with the sliding plates 45 on the front and rear sides of the connecting seat 2. Then, the knob 44 is turned, and the knob 44 drives the threaded column 43 to rotate in the threaded hole 22. Due to the sliding restriction of the sliding guide rod 42 in the insertion hole 21, the sliding push plate 41 can only slide along the front and rear direction of the connecting seat 2, thereby pushing the sliding plate 45 into the fixing slot 31 to achieve the initial fixation of the monitoring device body 3. As the sliding plate 45 continues to be inserted, the pressing sleeve 48 is first pressed by the inner wall of the fixing slot 31. The pressing sleeve 48 drives the transverse T-shaped push plate 46 to slide in the sliding groove, thereby compressing the top spring 47. At this time, the sliding plate 45 and the pressing sleeve 48 gradually approach each other, and through the transmission of the pushing plate 49 The function of the vertical top plate 410 is to push the vertical top plate 410 to move and tighten it on both sides of the fixed slot 31, thereby achieving secondary reinforcement of the monitoring equipment body 3. This fixing method is simple to operate, and installation can be completed by simply turning the knob 44. Compared with the traditional complex connection structure, it greatly shortens the installation time and improves work efficiency. In addition, the tightening effect of the vertical top plate 410 makes the connection between the monitoring equipment body 3 and the connecting seat 2 more stable, effectively avoiding the problem of inaccurate monitoring data caused by loosening, and ensuring the reliability of the monitoring equipment body 3 in monitoring the operating status of the motor body 1. When it is necessary to disassemble the monitoring equipment body 3, turn the knob 44 in the opposite direction, the sliding push plate 41 drives the sliding card plate 45 to move outward, the tightening spring 47 resets and pushes the horizontal T-shaped push plate 46, so that the vertical top plate 410 is released from the tightening on both sides of the fixed slot 31, and the monitoring equipment body 3 can be easily removed, which facilitates the maintenance and replacement of the equipment.

[0031] Example 2: Figure 4 and Figure 5As shown, this utility model provides a technical solution: the heat dissipation assembly 5 includes a heat dissipation frame 51, which is disposed on the top of the monitoring device body 3. Two connecting lugs 52 are fixedly connected to the left and right sides of the outer surface of the heat dissipation frame 51. The connecting lugs 52 are fixed to the top of the monitoring device body 3 by screws. A through-type heat dissipation groove 53 is provided inside the heat dissipation frame 51. Dust filters 54 are fixedly connected to the front and rear sides of the inner surface of the through-type heat dissipation groove 53. An annular cooling groove 55 is provided in the middle of the heat dissipation frame 51. The front and rear ends of the annular cooling groove 55 are respectively through-type heat dissipation groove 51. Inside the main body 3 of the monitoring device, on both the front and rear sides, the inner surface of the annular cooling tank 55 is fixedly connected with a number of metal heat-conducting plates 56 in an annular array. Each side of the metal heat-conducting plate 56 is provided with a flow groove 57. The two flow grooves 57 are respectively connected to the interior of the heat dissipation tank 53 and the annular cooling tank 55. The inner wall of the heat dissipation tank 53 is fixedly connected with a bidirectional motor 58 on both the front and rear sides. One end of the output shaft of the bidirectional motor 58 is fixedly connected to a heat dissipation fan 59. The other end of the output shaft of the bidirectional motor 58 passes through the interior of the annular cooling tank 55 and is fixedly connected to a guide fan 510.

[0032] The overall effect of Embodiment 2 is as follows: When the monitoring device body 3 generates heat during the monitoring of the operating status of the motor body 1, the bidirectional motor 58 is started. The bidirectional motor 58 drives the guide fan 510 and the exhaust fan 59 to rotate simultaneously. The rotation of the guide fan 510 causes the hot air inside the monitoring device body 3 to flow in the annular cooling groove 55. The hot air passes through the flow groove 57 on one side of the metal heat-conducting plate 56. The metal heat-conducting plate 56 has good thermal conductivity and can quickly absorb the heat of the hot air and transfer it to the loop-shaped exhaust groove 53. At the same time, the rotation of the exhaust fan 59 drives the external cold air to flow in the loop-shaped exhaust groove 53. The cold air interacts with the metal heat-conducting plate 56 in the loop-shaped exhaust groove 53. Heat exchange is performed, carrying away the heat transferred from the metal heat-conducting plate 56 and dissipating it through the front and rear ends of the U-shaped heat dissipation groove 53, achieving rapid heat dissipation. This heat dissipation method, through the design of the annular cooling groove 55 and the U-shaped heat dissipation groove 53, forms an efficient airflow channel, which greatly improves the heat dissipation efficiency compared to the traditional simple heat dissipation hole combined with fan heat dissipation method. The setting of the metal heat-conducting plate 56 increases the heat dissipation area, further improving the heat dissipation effect. At the same time, the dust filter 54 in the U-shaped heat dissipation groove 53 can effectively prevent dust from entering the equipment, avoid electronic component failure caused by dust accumulation, extend the service life of the monitoring equipment body 3, and ensure the long-term stable operation of the monitoring equipment body 3.

[0033] The working principle of the entire device is as follows: During the operation of the new energy trailer, the drive motor body 1 is in a high-load operation state for a long time. The monitoring device body 3 is electrically connected to the motor body 1 through wires to monitor the operating parameters of the motor body 1 in real time, such as the motor current, voltage, speed, temperature and other data. When the monitoring device body 3 detects abnormal changes in the motor operating parameters and reaches the preset fault warning threshold, the warning module inside the monitoring device body 3 will immediately issue a warning signal and notify relevant personnel through sound and light alarm or wireless transmission, so that maintenance personnel can take timely measures to avoid the fault from expanding and causing more serious consequences.

[0034] During the monitoring process, the monitoring device body 3 continuously generates heat. At this time, the heat dissipation component 5 plays a role. The bidirectional motor 58 drives the guide fan 510 and the heat dissipation fan 59 to rotate. Through the coordinated work of the annular cooling groove 55, the U-shaped heat dissipation groove 53 and the metal heat conduction plate 56, the heat generated by the monitoring device body 3 is quickly dissipated, ensuring that the monitoring device body 3 works stably in a suitable temperature environment. At the same time, the fixing component 4, through the cooperation of components such as the knob 44, the threaded column 43, the sliding push plate 41 and the sliding clamp 45, firmly fixes the monitoring device body 3 on the connecting seat 2, ensuring that the monitoring device body 3 will not loosen due to bumps or other conditions during the trailer's travel, and ensuring the accuracy and reliability of the monitoring data.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
