[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-5 As shown, this utility model discloses a vehicle-mounted electric cable reel, comprising: Support assembly 1, the support assembly 1 includes a base frame 11 and a roller 12, a drive shaft 13 is arranged between the base frames 11, and the roller 12 is sleeved on the drive shaft 13; Drive assembly 2 includes a drive source 21, a drive bevel gear 22 and a first bevel gear 23. The drive source 21 is mounted on the base frame 11. The drive bevel gear 22 is mounted on the output end of the drive source 21. The first bevel gear 23 is sleeved on the transmission shaft 13 and meshes with the drive bevel gear 22. The controller 3 is located on one side of the base frame 11. The controller 3 is equipped with a forward / reverse switch 31, a speed control knob 32, and a circuit breaker 33. The forward / reverse switch 31 and the speed control knob 32 are both electrically connected to the drive source 21, and the circuit breaker 33 is electrically connected to the forward / reverse switch 31.

[0019] The base frame 11 in this invention can be directly connected to and fixed to a vehicle. The roller 12 is fixedly connected to the drive shaft 13, which is positioned between the base frame 11, providing support for both the drive shaft 13 and the roller 12. Rotating the drive shaft 13 causes the roller 12 to rotate. Specifically, the drive shaft 13 is driven by a drive source 21. A first bevel gear 23 is mounted on the drive shaft 13. The output shaft of the drive source 21 is equipped with a drive bevel gear 22. The axial direction of the first bevel gear 23 is perpendicular to the axial direction of the drive bevel gear 22. Rotation of the drive source 21 drives the drive bevel gear 22 to rotate. The drive bevel gear 22 meshes with the first bevel gear 23, and the first bevel gear 23 moves synchronously, driving the drive shaft 13 to rotate, thereby achieving the rotation of the roller 12. The driver is used to control the drive source 21. As a preferred embodiment of this invention, the drive source 21 is a DC brushless motor with a built-in motor driver for receiving control signals and then controlling the motor's state. Specifically, refer to... Figure 4 As shown, the forward / reverse switch 31 is electrically connected to the drive source 21 and is used to control the forward and reverse rotation of the drive source 21 to realize the take-up and release actions. The speed control button is connected to the drive source 21 and is used to control the speed of the drive source 21 to achieve stepless speed regulation, allowing the selection of a suitable speed for take-up and release actions. The circuit breaker 33 is connected to the forward / reverse switch 31 and is set between the forward / reverse switch 31 and the power supply. When a circuit fault or abnormality occurs, the power supply is quickly cut off to avoid equipment damage, fire, or other dangers. In addition, in this utility model, the power supply of the drive source 21 is introduced from the vehicle's battery. The circuit breaker 33 can also cut off the circuit in time to prevent the vehicle's battery from running out of power.

[0020] In this invention, the speed control knob 32 controls the DC brushless motor to achieve stepless speed regulation of the cable reel, avoiding wear and tear on the cable during winding and unwinding. Secondly, the circuit breaker 33 controls the power supply connection status. When an overload occurs or the motor / controller 3 overheats, the circuit can be cut off, effectively protecting the core equipment from damage and preventing safety accidents.

[0021] Furthermore, referring to Figure 3 As shown, the drive assembly 2 further includes a manual input shaft 25 and a second bevel gear 24. The second bevel gear 24 is sleeved on the manual input shaft 25 and meshes with the drive bevel gear 22. A crank handle 26 is provided at the end of the manual input shaft 25 away from the second bevel gear 24, and the crank handle 26 is detachably connected to the manual input shaft 25.

[0022] In this invention, the power source for the drive source 21 is the vehicle's battery. When the vehicle's battery is low on power, the cable can be wound and unwound via the manual input shaft 25. Specifically, one end of the manual input shaft 25 meshes with the first bevel gear 23 via the second bevel gear 24, driving the manual input shaft 25 and thus rotating the roller 12. The manual input shaft 25 can be driven by the crank handle 26. As a preferred embodiment of this invention, the end of the manual input shaft 25 that mates with the crank handle 26 has a multi-faceted structure. The crank handle 26 is made of seamless steel pipe and has multi-faceted holes that mate with the manual input shaft 25.

[0023] Furthermore, referring to Figure 5 As shown, the roller 12 is provided with baffles 14 at both ends along the axial direction; a spring pin 16 is provided on one side of the base frame 11, and the surface of the baffle 14 is provided with a limiting hole 141 that cooperates with the spring pin 16.

[0024] Specifically, baffles 14 are provided at both ends of the roller 12 to limit the height of the coiled cable. During cable winding and unwinding, the baffles 14 rotate synchronously with the roller 12. The base frame 11 is fixed on the vehicle, and spring pins 16 are set on the base frame 11 to limit the roller 12 and prevent the cable from scattering due to the rotation of the roller 12 during transportation.

[0025] Furthermore, referring to Figure 2 As shown, the roller 12 is provided with reinforcing discs 15 at both ends, and the reinforcing discs 15 are detachably connected to the baffle 14.

[0026] Specifically, during the assembly process, the reinforcing disc 15 is welded and fixed to the inner wall of the drum 12, and then the reinforcing disc is connected to the baffle 14 by bolts. The drum 12 and the baffle 14 are fixedly connected by welding. The reinforcing disc can improve the strength of the drum 12 and withstand larger cables.

[0027] Furthermore, referring to Figure 2 and Figure 5 As shown, one of the baffles 14 is provided with a quick aviation socket 17 on the side away from the roller 12.

[0028] Specifically, the aviation socket 17 is connected to the cable on the cable reel. During use, the external wiring harness can be directly connected to the aviation socket 17 without having to lay out the entire cable reel, thus enabling convenient use of the cable.

[0029] Furthermore, referring to Figure 5 As shown, the controller 3 is equipped with an indicator light 34, which is electrically connected to the drive source 21.

[0030] Specifically, indicator light 34 is connected to the motor driver built into the drive source 21 (DC brushless motor) to provide feedback on the working status of the drive source 21. As a preferred embodiment of this utility model, indicator light 34 includes both red and green lights. When the drive source 21 is working normally, the green indicator light 34 lights up; when the drive source 21 malfunctions, the red indicator light 34 lights up to remind the operator to perform timely maintenance.

[0031] Furthermore, referring to Figure 2 As shown, the drive shaft 13 and the base frame 11 are connected by a rolling bearing 19. The bearing 19 supports the drive shaft 13, preventing direct contact between the drive shaft 13 and the base frame 11, and improves the rotational flexibility of the drive shaft 13.

[0032] Furthermore, referring to Figure 2 As shown, a mounting base 18 is provided on the top of the base frame 11, and the drive source 21 is detachably connected to the mounting base 18. Specifically, the mounting base 18 is provided on the top of the base frame 11 for mounting and fixing the drive source 21.

[0033] In summary, this utility model introduces a vehicle-mounted electric cable reel. In this utility model, the speed control knob 32 controls the DC brushless motor to achieve stepless speed regulation of the cable reel, avoiding wear and tear on the cable during winding and unwinding. Secondly, the circuit breaker 33 controls the power supply connection status. When an overload occurs or the motor / controller 3 overheats, the circuit can be cut off, which can effectively protect the core equipment from damage and avoid safety accidents.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
