[0051] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0052] The accompanying drawings illustrate schematic diagrams of layer structures according to embodiments of the present invention. These figures are not drawn to scale; for clarity, some details are exaggerated and some details may be omitted. The shapes, relative sizes, and positional relationships of the various regions and layers shown in the figures are merely exemplary and may deviate in practice due to manufacturing tolerances or technical limitations. Those skilled in the art may design regions / layers with different shapes, sizes, and relative positions based on actual needs.

[0053] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] In the description of the present invention, it should be noted that the terms “first”, “second”, “third” and “fourth” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0055] Combine Figures 1 to 9 The present invention provides a vehicle-mounted cable reel device, including a reel bracket 1, a drive assembly 2, a transmission assembly 3 and a retractable assembly 4; the drive assembly 2 is fixedly connected to the reel bracket 1, the transmission assembly 3 is connected to the reel bracket 1, and the retractable assembly 4 is connected to the transmission assembly 3; the drive assembly 2 drives the retractable assembly 4 to rotate through the transmission assembly 3, and the retractable assembly 4 is used to carry the cable and retract or release the cable by rotating.

[0056] Specifically, the reel bracket 1 is fixed on the vehicle body, such as the compartment of the emergency power supply vehicle, and serves as the basic support structure of the entire device, and is used to fix all components such as the drive component 2, transmission component 3, and retraction component 4, to ensure the relative position of each component is stable, and to provide an installation reference for the entire device; the drive component 2 provides a power source, providing driving force for the rotation of the retraction component 4; the transmission component 3 connects the drive component 2 and the retraction component 4, and is responsible for transmitting the power of the drive component 2 to the retraction component 4 to realize power transmission; the retraction component 4 directly carries the cable and realizes the storage or release of the cable through its own rotation. During operation, the drive component 2 is fixed on the reel bracket 1 and outputs power, which is transmitted to the retraction component 4 through the transmission component 3, driving the retraction component 4 to rotate; the retraction component 4 realizes the storage or release of the cable by rotation, thereby completing the cable storage operation.

[0057] Through such a setting, a drive component 2, a transmission component 3 and a retracting component 4 are set on the reel bracket 1 to realize the mechanized operation of cable retraction and release, reduce labor input and reduce costs; and the drive component 2 drives the retracting component 4 to rotate through the transmission component 3, providing power for the retraction and release of the cable, thereby improving the efficiency of cable retraction and release. The drive component 2, the transmission component 3 and the retracting component 4 are integrated into one through the reel bracket 1, with a compact structure, improved space utilization, suitable for vehicle installation, and reduced installation complexity caused by the dispersion of components, so that the cable retraction, storage and transportation processes are coherent, avoiding efficiency loss caused by component matching problems during operation, and making the operation more convenient during the cable retraction and release process. The cable retraction and release is realized by rotating the retracting component 4, and the movement path of the cable during the retraction and release process is more stable, further improving the cable retraction and release efficiency, and being more orderly than manual retraction and release, reducing the friction of the cable caused by disordered retraction and release, which causes cable damage, and is conducive to protecting the cable.

[0058] It should be noted that the specific connection relationship between the retractable assembly 4 and the transmission assembly 3 is not limited here. It can be a fixed connection, such as a snap connection, a screw connection, or a key connection. In this case, the transmission assembly 3 and the retractable assembly 4 rotate together, and the retractable assembly 4 completes the storage or release of the cable by controlling the rotation direction of the drive assembly 2. It can also be a rotational connection, such as a connection via a bearing structure. In this case, a connecting structure can be provided. When the retractable assembly 4 and the transmission assembly 3 need to rotate together, the retractable assembly 4 and the transmission assembly 3 are connected via the connecting structure. When the two do not need to rotate together, the connecting structure can be detached, and the retractable assembly 4 can be rotated relative to the transmission assembly 3, thereby realizing manual rotation of the retractable assembly 4 and increasing flexibility during use.

[0059] In a preferred case, the retractable assembly 4 and the transmission assembly 3 are rotationally connected, and the vehicle-mounted cable reel device also includes a clutch assembly 5, which is connected to the transmission assembly 3; when the clutch assembly 5 is connected to the retractable assembly 4, the transmission assembly 3 and the retractable assembly 4 rotate together; when the clutch assembly 5 is not connected to the retractable assembly 4, the retractable assembly 4 can rotate alone.

[0060] Specifically, the clutch assembly 5 connects the transmission assembly 3 and the retractable assembly 4. By adjusting the connection and disconnection between the clutch assembly 5 and the retractable assembly 4, power transmission between the transmission assembly 3 and the retractable assembly 4 is controlled. When connected, power transmission is allowed, and when disconnected, power transmission is cut off, thereby achieving automatic and manual mode switching. When the clutch assembly 5 is connected to the retractable assembly 4, power from the transmission assembly 3 can be transmitted to the retractable assembly 4, and the two rotate synchronously. When the clutch assembly 5 is disconnected from the retractable assembly 4, power from the transmission assembly 3 cannot be transmitted, and the retractable assembly 4 can rotate independently of the transmission assembly 3. This switching between these two states allows for flexible selection of operating modes.

[0061] It should be noted that the specific connection relationship between the clutch assembly 5 and the transmission assembly 3 is not limited here. It can satisfy that the clutch assembly 5 and the transmission assembly 3 rotate together, and the clutch assembly 5 can slide on the transmission assembly 3, thereby realizing the connection and separation operations of the clutch assembly 5 and the retractable assembly 4.

[0062] Through this configuration, the connection and disconnection functions of the clutch assembly 5 allow the device to flexibly switch between automatic and manual modes. For example, if a hydraulic system failure occurs during an uninterrupted operation, manual mode can be immediately switched to avoid interruption, enabling the device to cope with complex operating scenarios. The clutch assembly 5 enables rapid mode switching without the need for complex procedures, reducing time wasted due to cumbersome operational procedures. In the disconnected state, the retractable assembly 4 rotates independently, preventing the sudden pulling of the cable caused by erroneous power transmission in automatic mode, which could damage the cable and injure the operator, thereby reducing safety risks.

[0063] It should be noted that the specific structure of the driving assembly 2 is not limited here, and it only needs to be able to drive the transmission assembly 3 to drive the retractable assembly 4 to rotate, for example, by an electric motor or a hydraulic motor 21.

[0064] In a preferred embodiment, the drive assembly 2 includes a hydraulic motor 21 and a first support 22. The hydraulic motor 21 and the first support 22 are fixedly connected. The first support 22 is fixedly connected to the reel support 1. The output end of the hydraulic motor 21 is connected to the transmission assembly 3. Specifically, the hydraulic motor 21 serves as the power source of the drive assembly 2, converting hydraulic energy into mechanical energy, outputting rotational power, driving the transmission assembly 3 to move, and thereby driving the retractable assembly 4 to rotate. The first support 22 is used to fix the hydraulic motor 21. Through its fixed connection with the reel support 1, it ensures the installation stability of the hydraulic motor 21 during operation.

[0065] Through such a setting, the hydraulic motor 21 can directly use the vehicle's own hydraulic system as a power source, without the need for an additional independent power unit, saving compartment space, reducing the overall weight of the device, and meeting the lightweight requirements of vehicle-mounted equipment. The hydraulic motor 21 has a large torque and an adjustable speed. The retraction and extension speed can be accurately controlled by the controller to avoid cable stretching and deformation due to excessive power, or retraction and extension jamming due to insufficient power, protecting the cable and ensuring stable operation of the device. The hydraulic motor 21 is firmly fixed to the reel bracket 1 through the first support 22, such as welding or screwing, so it is not easy to loosen when the vehicle is bumpy, ensuring the stability of power output and reducing component wear caused by vibration.

[0066] It should be noted that the specific driving method of the hydraulic motor 21 is not limited here. In a preferred case, a switch 8 is provided on the reel bracket 1, and the switch 8 is connected to the hydraulic motor 21 through a hydraulic oil pipe. The switch 8 controls the connection or disconnection of the hydraulic oil in the hydraulic oil pipe, thereby realizing the operation or stop of the hydraulic motor 21.

[0067] It should be noted that the specific structure and transmission mode of the transmission assembly 3 are not limited here, and power transmission can be achieved through a gear set, belt drive or chain drive. It is sufficient that the power of the drive assembly 2 can be stably transmitted to the retractable assembly 4.

[0068] In a preferred case, the transmission assembly 3 includes an output sprocket 31, a driven sprocket 32, a chain 33 and a rotating shaft 34. The output sprocket 31 is connected to the driven sprocket 32 ​​through the chain 33. The driven sprocket 32 ​​is fixedly connected to the rotating shaft 34. The output sprocket 31 is fixedly connected to the output end of the driving assembly 2. The rotating shaft 34 is rotatably connected to the transmission assembly 3.

[0069] Specifically, the output sprocket 31 is fixedly connected to the output end of the drive assembly 2, receiving power from the drive assembly 2 and transmitting it to the chain 33. The driven sprocket 32 ​​is fixedly connected to the rotating shaft 34, receiving power from the output sprocket 31 via the chain 33, driving the rotating shaft 34 to rotate. The rotating shaft 34 is fixedly connected to the driven sprocket 32, transmitting the rotational power of the driven sprocket 32 ​​to the retractable assembly 4. During operation, the drive assembly 2 drives the output sprocket 31 to rotate, which in turn drives the driven sprocket 32 ​​to rotate via the chain 33. The driven sprocket 32 ​​then drives the rotating shaft 34 to rotate synchronously. The rotating shaft 34 then transmits power to the retractable assembly 4, causing it to rotate.

[0070] This arrangement, employing a chain drive, ensures the load-bearing capacity of transmission assembly 3, enabling it to transmit the high torque output by hydraulic motor 21. It is compatible with heavy flexible cables, such as the thicker cables commonly used in non-stop power operations, and avoids the slippage issues associated with belt drives and other transmission methods. The output sprocket 31 and driven sprocket 32 ​​are rigidly engaged by a chain 33, minimizing power transmission losses. Each sprocket is secured to the shaft via a keyed connection, minimizing displacement deviation during transmission and ensuring consistent rotation of retractable assembly 4. The chain 33 and sprockets feature a simple structure and can be replaced individually if worn, eliminating the need for complete disassembly. This facilitates quick maintenance, particularly during outdoor operations, and reduces equipment downtime.

[0071] It should be noted that the specific number of the retractable components 4 is not limited here. One retractable component 4 may be provided on the reel bracket 1 to store the cables on the retractable component 4. Alternatively, multiple retractable components 4 may be provided to store multiple groups of cables respectively.

[0072] In a preferred case, the vehicle-mounted cable reel device includes multiple retractable components 4, the transmission component 3 includes multiple driven sprockets 32 and multiple rotating shafts 34, the multiple retractable components 4, the driven sprockets 32 and the rotating shafts 34 are arranged correspondingly, and the multiple retractable components 4 are horizontally arranged on the reel bracket 1 and arranged in sequence in the vertical direction.

[0073] Specifically, multiple retractable assemblies 4 independently carry cables, increasing the device's total cable storage capacity and enabling simultaneous or independent retraction of multiple cables. Multiple driven sprockets 32 and rotating shafts 34 correspond one to each retractable assembly 4, providing power to each retractable assembly 4 and ensuring independent rotation. Each retractable assembly 4 is also equipped with a corresponding clutch assembly 5. By adjusting the connection or disconnection relationship between each clutch assembly 5 and the multiple retractable assemblies 4, the multiple retractable assemblies 4 can be flexibly configured to rotate with the transmission assembly 3 or independently. The multiple retractable assemblies 4 are arranged vertically on the reel support 1, fully utilizing the vertical space and minimizing the horizontal space occupied.

[0074] This arrangement allows multiple retractable components 4 to be arranged vertically, enabling layered storage of multiple cables within the limited height of the carriage. This solves the problem of insufficient storage capacity in a single component and is suitable for simultaneous operation of multiple lines. Different retractable components 4 can store cables of different specifications, such as lengths and cross-sections, allowing for quick access to the corresponding cables during operation, avoiding confusion caused by mixed storage and improving work preparation efficiency. The vertical arrangement reduces horizontal space occupied, and each component is independently driven. By controlling the clutch component 5, a single layer can be operated independently, avoiding energy waste caused by the linkage of multiple components.

[0075] It should be noted that when each driven sprocket 32 ​​is fixed to the reel bracket 1, a sprocket guard is provided on the outside of the driven sprocket 32. The sprocket guard is fixedly connected to the reel bracket 1 to protect the driven sprocket 32 ​​and avoid the risk of accidental injury caused by direct exposure of the driven sprocket 32. The output sprocket 31 is preferably arranged on the inside of the reel bracket 1 to save overall space and avoid the risk of accidental injury caused by the exposure of the output sprocket 31.

[0076] In a preferred case, the vehicle-mounted cable reel device also includes a tensioning assembly 6, which is used to adjust the tightness of the chain 33; the tensioning assembly 6 includes a second support 61 and a tensioning sprocket 62, the second support 61 is connected to the tensioning sprocket 62, the second support 61 is fixedly connected to the reel bracket 1, and the tensioning sprocket 62 is connected to the chain 33.

[0077] Specifically, the tensioning assembly 6 ensures the stability of the chain drive by adjusting the tightness of the chain 33, preventing the chain 33 from slipping due to being too loose or wearing due to being too tight; the second support 61 fixes the tensioning sprocket 62, providing an installation reference for the tensioning sprocket 62; the tensioning sprocket 62 engages with the chain 33, and adjusts the tension of the chain 33 by changing its own position or the diameter of the engagement with the chain 33.

[0078] The specific method of adjusting the tightness of the chain 33 is not limited here. In an optional situation, a sliding groove 61a is provided on the second support 61, and a fastening bolt 63 is passed through the sliding groove 61a to be fixedly connected to the reel bracket 1, thereby fixing the position of the tensioning sprocket 62. When it is necessary to adjust the position of the tensioning sprocket 62, the position of the sliding groove 61a and the fastening bolt 63 is adjusted to adjust the position of the second support 61 and complete the adjustment of the tightness of the chain 33. The specific position of the tensioning sprocket 62 on the chain 33 is not limited here either, and it can be on the inner and outer sides of the chain 33, and the path formed by the chain 33 is changed to adjust the tightness of the chain 33. Figure 2 and Figure 3 As shown, the tensioning sprocket 62 is positioned outside the chain 33. Initially, the section of chain 33 between the output sprocket 31 and the driven sprocket 32 ​​is a straight line. To tighten the chain 33, the second support 61 moves upward, and the tightening bolt 63 and the sliding slot 61a move relative to each other. This section of chain 33 bends at the tensioning sprocket 62, increasing the length of the chain 33 and tightening the entire chain 33. The tightening bolt 63 then secures the second support 61. The operations for loosening and tightening the chain 33 are reversed and will not be further described here.

[0079] With this arrangement, the tensioning sprocket 62 can be adjusted in position via the second support 61, compensating for the elongation of the chain 33 due to long-term use. This prevents tooth skipping and unusual noise caused by an overly loose chain 33, or excessive sprocket wear caused by an overly tight chain 33, thereby extending the service life of the transmission assembly 3. Vehicle vibrations in a vehicular environment can cause variations in the tightness of the chain 33. The tensioning assembly 6 can buffer these variations in real time, ensuring stable transmission efficiency. This is particularly important when temporarily retracting or releasing the cable while the vehicle is in motion, reducing transmission interruptions caused by vibration. The second support 61 is secured by a fastening bolt 63, allowing adjustment of tension without specialized tools. Maintenance can be performed outdoors, improving work efficiency.

[0080] It should be noted that the specific structure of the retractable assembly 4 is not limited here, as long as it can be rotated on the transmission assembly 3 to retract the cable. In a preferred embodiment, the retractable assembly 4 includes a cylinder 41, a bearing 42, and a ring 43. The cylinder 41 is sleeved on the rotating shaft 34 and is rotatably connected to it via the bearing 42. The ring 43 is fixedly connected to the surface of the cylinder 41.

[0081] Specifically, the barrel 41 serves as the main body for winding the cable, directly bearing the cable. Its cylindrical structure ensures that the cable is wound neatly and avoids damage to the cable. The bearing 42 is arranged between the barrel 41 and the rotating shaft 34 to reduce the friction resistance when the two rotate relative to each other, so that the barrel 41 can rotate flexibly. The ring 43 is fixed to the surface of the barrel 41 and distributed along the axial direction of the barrel 41, limiting the winding range of the cable on the barrel 41 and preventing the cable from moving axially along the barrel 41. In automatic mode, that is, when the clutch assembly 5 is connected to the retractable assembly 4, the barrel 41 rotates synchronously with the rotating shaft 34, and the cable is wound on or unfolded from the barrel 41. In manual mode, the barrel 41 rotates freely relative to the rotating shaft 34 through the bearing 42, which is convenient for manually pulling the cable to achieve retraction and extension. The ring 43 blocks the cable from moving toward the two ends of the barrel 41, ensuring that the cable is wound within the set range and avoiding falling off.

[0082] With this arrangement, the barrel 41 is cylindrical, and cooperates with the rings 43 at both ends to ensure that the cable is evenly distributed along the axial direction when it is wound, avoiding cable extrusion and deformation caused by local accumulation, and especially protecting the insulation layer of the flexible cable. The bearing 42 reduces the friction resistance between the barrel 41 and the rotating shaft 34, making it easier to manually pull the cable. For example, when the end of the cable is connected to the line, the barrel 41 can be manually fine-tuned to rotate, accurately controlling the cable length and reducing the physical exertion of the operator. The ring 43 is fixed to the outside of the barrel 41, such as by welding or screwing, to form a physical barrier. Even if the vehicle is bumpy during driving, the cable will not slip from both ends of the barrel 41, ensuring stable cable storage.

[0083] It should be noted that the specific arrangement of the ring 43 on the outer surface of the cylinder 41 and the structural form of the ring 43 are not limited here. In an optional case, such as Figure 4 As shown, the ring 43 is provided with a plurality of first rings 431 and a plurality of second rings 432, and the first rings 431 and the second rings 432 are alternately arranged on the outside of the cylinder 41 and are both perpendicular to the axis of the cylinder 41, wherein the second ring 432 is a double-ring reinforcement structure, that is, the two ring portions are connected to increase the overall strength of the second ring 432. The specific winding method of the cable on the cylinder 41 is not limited here. It can be wound only between the first ring 431 and the second ring 432 to ensure the overall stability of the cable after storage; or the size of the rings 43 at both ends of the cylinder 41 can be increased (not shown in the figure) to limit the cable wound on both ends of the cylinder 41. At this time, the cable can be wound between the first ring 431 and the second ring 432, and can continue to be wound circumferentially around the first ring 431 and the second ring 432 to ensure the stability of the cable after winding, while increasing the retractable length of the cable.

[0084] In a preferred embodiment, the retractable assembly 4 further includes a reinforcing web 44, which is fixedly connected to the inner arm of the cylinder 41 and to the bearing 42. Specifically, the reinforcing web 44 is fixed to the inner wall of the cylinder 41 and distributed axially along the cylinder 41, thereby enhancing the structural strength of the cylinder 41 and connecting the bearing 42 to the cylinder 41 to ensure the installation stability of the bearing 42. The reinforcing web 44 is fixed to the inner wall of the cylinder 41 by welding or other means, dispersing the radial force exerted on the cylinder 41 during cable winding and preventing deformation of the cylinder 41. Furthermore, the reinforcing web 44 provides a stable installation foundation for the bearing 42, ensuring that the relative position of the bearing 42 and the cylinder 41 is fixed and that the bearing 42 rotates smoothly.

[0085] It should be noted that the specific number of reinforcing webs 44 is not limited here. According to the size and usage requirements of the cylinder 41, multiple reinforcing webs 44 can be set. Multiple reinforcing webs 44 correspond to multiple bearings 42, which are evenly distributed along the axial direction of the cylinder 41 to improve the overall strength of the cylinder 41.

[0086] Through such a setting, the reinforcing web 44 is welded to the inner wall of the cylinder 41, dispersing the radial pressure generated when the cable is wound, preventing the cylinder 41 from bulging or deforming due to long-term stress, ensuring balanced winding, and extending the service life of the cylinder 41. The reinforcing web 44 provides rigid support for the bearing 42, preventing the bearing 42 from shaking due to uneven force when the cylinder 41 rotates, reducing friction and wear between the bearing 42 and the shaft, ensuring smooth rotation, and improving overall stability. The reinforcing web 44 adopts a hollow or thin design, such as providing a through hole in the reinforcing web 44, which does not significantly increase the weight of the device while enhancing strength, reducing the overall weight of the retractable assembly 4, and making it easier to operate, especially when manual rotation is required.

[0087] It should be noted that the specific structure of the clutch assembly 5 is not limited herein. The rotation mode of the retractable assembly 4 can be adjusted by adjusting the connection or separation between the clutch assembly 5 and the retractable assembly 4. In a preferred embodiment, the clutch assembly 5 includes a clutch 51, a shift fork 52, a shift lever 53, a third support 54, and a first spring 55. The clutch 51 is provided with a first latch 511. A first connecting hole 42a is formed on the side of the bearing 42. The first latch 511 is adapted to fit within the first connecting hole 42a. The clutch 51 is formed with a groove 51a. The end of the shift fork 52 is disposed within the groove 51a. The shift fork 52 is fixedly connected to the shift lever 53. The shift lever 53 is rotationally connected to the third support 54. The third support 54 is fixedly connected to the reel bracket 1. One end of the first spring 55 is connected to the clutch 51. The other end of the first spring 55 is connected to the rotating shaft 34. The clutch 51 is connected to the rotating shaft 34. The clutch 51 rotates synchronously with the rotating shaft 34 and can slide along the axial direction of the rotating shaft 34.

[0088] Specifically, the clutch 51 engages the first connecting hole 42a of the bearing 42 via the first latch 511, thereby connecting or disconnecting the clutch 51 from the bearing 42 and switching the operating mode of the retractable assembly 4. The specific structural form of the first connecting hole 42a and the first latch 511 is not limited herein. The first latch 511 may be a plurality of cylinders evenly arranged around the circumference of the clutch 51 and oriented toward the bearing 42. The first connecting hole 42a and the first latch 511 have the same orientation and may be a through hole formed axially along the bearing 42, or multiple holes formed on the side of the bearing 42 proximal to the clutch 51. In this case, the depth and diameter of the multiple holes match the dimensions of the first latch 511. The end of the shift fork 52 is inserted into the groove 51a of the clutch 51. By shifting the clutch 51 and sliding it axially along the rotating shaft 34, the engagement between the first latch 511 and the first connecting hole 42a is controlled. The specific formation method of the groove 51a is not limited herein. The groove 51a can be formed on the clutch 51, with the end of the shift fork positioned within the groove 51a. Alternatively, a baffle plate can be provided on the side of the clutch 51 near the shift fork 52, with an annular groove 51a formed between the baffle plate and the clutch 51. The shift lever 53 is fixedly connected to the shift fork 52. The shift lever 53 rotates about a third support 54 fixed to the reel bracket 1, thereby driving the shift fork 52. The first spring 55 is connected at both ends to the clutch 51 and the rotating shaft 34, respectively, providing an axial reset force for the clutch 51, allowing the clutch 51 to automatically engage with the retractable assembly 4 in the absence of external force.

[0089] During operation, the clutch assembly 5 adjusts the operating mode of the retractable assembly 4. In automatic mode, the first spring 55 pushes the clutch 51 to slide axially along the rotating shaft 34. The first latch 511 inserts into the first connecting hole 42a of the bearing 42, engaging the clutch 51 and the retractable assembly 4. The rotating shaft 34 drives the clutch 51 and the retractable assembly 4 to rotate synchronously. In manual mode, the shift lever 53 is rotated, which drives the shift fork 52 to push the clutch 51 to slide against the elastic force of the first spring 55. The first latch 511 disengages the first connecting hole 42a, separating the clutch 51 from the retractable assembly 4 and allowing the retractable assembly 4 to rotate independently. When the shift lever 53 is released, the first spring 55 pulls the clutch 51 back to its original position, reengaging it.

[0090] It should be noted that the specific connection method between the clutch 51 and the rotating shaft 34 is not limited here, as long as the clutch 51 can rotate together with the rotating shaft 34 and can slide along the axial direction of the rotating shaft 34. A slot structure along the axial direction of the rotating shaft 34 can be set between the clutch 51 and the rotating shaft 34, or the clutch 51 and the rotating shaft 34 are connected by a key and the clutch 51 can slide along the axial direction of the rotating shaft 34. The specific structure of the shift fork 52 and the shift lever 53 is also not limited, such as Figure 9As shown, two shift forks 52 can be mounted on the shift rod 53 in a facing manner. The ends of the two shift forks 52 are both disposed in the groove 51a. When the shift rod 53 rotates relative to the third support 54, the shift forks 52 drive the clutch 51 to slide along the axial direction of the rotating shaft 34. The shift rod 53 in the figure adopts a structure with a bent end, which makes it easier for the shift rod 53 to drive the shift forks 52 to swing.

[0091] This arrangement allows the clutch 51 to engage the hole in the bearing 42 via the first latch 511, combined with the mechanical transmission of the shift fork 52 and the shift lever 53, to rapidly switch the operating modes of the retractable assembly 4. A first spring 55 constantly provides a reset force for the clutch 51. This prevents accidental disengagement of the clutch 51 during vehicle motion or vibration, preventing the retractable assembly 4 from rotating freely. This prevents the cable from loosening or dragging due to inertia, ensuring safe transportation. The shift lever 53 rotates around the third support 54, and the lever structure design reduces effort, allowing operators to switch positions without significant physical effort. This allows for rapid response in emergency situations, improving operational efficiency.

[0092] In a preferred case, the vehicle-mounted cable reel device also includes a limiting assembly 7, which includes a second pin 71, a fourth support 72 and a second spring 73. The second pin 71 is movably connected to the fourth support 72, and a limiting rod 711 is provided on the second pin 71. One end of the second spring 73 is connected to the limiting rod 711, and the other end of the spring is connected to the fourth support 72. A second connecting hole 54a is formed on the third support 54, and the second pin 71 is adapted to the second connecting hole 54a. The fourth support 72 is fixedly connected to the shift rod 53.

[0093] Specifically, the second latch 71 engages with the second connection hole 54a of the third support 54. By being inserted into the second connection hole 54a, it limits the rotation of the lever 53 and secures the clutch assembly 5 in the disengaged state. The fourth support 72 is fixed to the lever 53, providing a mounting base for the second latch 71 and rotating synchronously with the lever 53. A second spring 73 connects the limiting rod 711 of the second latch 71 with the fourth support 72, providing the elastic force required for the second latch 71 to be inserted into the second connection hole 54a. The limiting rod 711 is provided on the second latch 71 to limit the sliding range of the second latch 71 and also serves as a connection point for the second spring 73. When the lever 53 rotates to the clutch disengagement position, the second pin 71 is automatically inserted into the second connecting hole 54a of the third support 54 under the action of the elastic force of the second spring 73, fixing the position of the lever 53 and keeping the clutch 51 in the disengaged state; when it is necessary to switch to the automatic mode, the second pin 71 is pulled to overcome the spring force and disengage from the second connecting hole 54a, the lever 53 can rotate freely, and the clutch 51 is reset and engaged under the action of the first spring 55.

[0094] It should be noted that the specific implementation method of the movable connection between the second latch 71 and the fourth support 72 is not limited here, nor is the specific structure of the fourth support 72 limited. Figure 8 The fourth support 72 is set to a right-angled U-shaped structure, the bottom of which is fixedly connected to the shift rod 53, and through holes are formed at both ends. The diameter of the through holes is adapted to the second latch 71, and the second latch slides at both ends of the fourth support 72. The second spring 73 abuts one end of the fourth support 72. When the shift rod 53 drives the fourth support 72 to rotate to the state where the clutch 51 and the bearing 42 are separated, the second latch 71 is pushed by the second spring 73 and enters the second connecting hole 54a, thereby keeping the first spring 55 in a compressed state. At this time, the retractable assembly enters the manual rotation mode.

[0095] With this arrangement, the second latch 71 automatically inserts into the hole in the third support 54 under the force of the spring, firmly securing the position of the lever 53. This prevents accidental engagement of the clutch 51 due to vibration or accidental contact during manual operation, ensuring that the device remains stable while the cable is being pulled. The latch automatically limits the position without requiring additional locking steps, reducing the number of steps and complexity required for the operator. The mechanical structure requires no electrical control and is unaffected by environmental factors such as rain and dust. It can operate stably even in harsh outdoor operating conditions, minimizing the risk of failure.
