Description

Technical Field

[0001] This invention belongs to the field of automotive auxiliary components technology, specifically relating to a quick-release tractor saddle and its fixing method. Background Technology

[0002] The truck saddle, also known as the towing saddle, is the connecting device between the semi-trailer tractor and the semi-trailer. While it's often concealed by the semi-trailer during use, making it an inconspicuous component, it is nonetheless a crucial one. As a vital assembly connecting the tractor and semi-trailer, the towing saddle not only tows the semi-trailer and bears its load, but it must also withstand the impacts of the tractor's starting, acceleration, deceleration, steering, and braking maneuvers, as well as the impacts during semi-trailer engagement. Therefore, the strength and reliability of the towing saddle directly affect the driving safety of the semi-trailer.

[0003] Currently, there are many types of trailer tow seats on the market, such as the trailer tow seat adjustment structure with patent number CN202321080864.X. This trailer tow seat adjustment structure, through the setting of positioning components, pushes the locking parts on both sides through the cylinder and the top shafts on both sides, so that they are inserted into the slider. Several locking slots are inserted into the matching positioning slots to lock the slider. At the same time, when the locking parts are inserted, several positioning rods can be pressed down through the arc-shaped surface at their ends, so that they are inserted into several holes opened inside the reinforcing plate to achieve the locking operation. Compared with the traditional locking pin type positioning, it can improve the positioning strength of the tow seat plate, while reducing the force borne by the locking parts when locking, thus improving the service life of the component.

[0004] While trailer towing seats, as mentioned in the comparative cases above, are designed to allow for position adjustment, thus improving their usability, a series of problems still need to be addressed in practical applications:

[0005] First, regarding the friction between the lock hole and the locking bar. Friction between the lock hole and the locking bar is unavoidable during the operation of the trailer tow hitch. The traditional method to reduce this friction is to apply lubricating grease, such as grease, to the locking bar. However, the trailer tow hitch design in the aforementioned comparative case did not consider the need for automatic grease application. This means that every time the user needs to adjust the position of the tow hitch, grease must be manually applied to the locking mechanism. This operation is not only time-consuming and laborious but also hinders the adjustment of the tow hitch position, thus affecting overall operational efficiency.

[0006] More specifically, manually applying grease often needs to be done before adjusting the traction seat, which increases the user's workload. Furthermore, uneven application or insufficient application can lead to ineffective friction between the lock hole and the locking bar, thus affecting the stability and lifespan of the traction seat.

[0007] Secondly, there are inconveniences in applying grease to the hooks of trailer tow seats. As a crucial component of the trailer tow seat, the performance of the hook directly affects the overall usability of the tow seat. However, in actual use, due to the structural and positional limitations of the hook, it is difficult to effectively apply grease. This leads to problems such as wear or jamming of the hook during use, which in turn affects the stability and safety of the tow seat. Summary of the Invention

[0008] The purpose of this invention is to provide a quick-release towing vehicle saddle and its fixing method, which can quickly lock and unlock the towing seat, and automatically apply lubricating grease to the locking rod during the unlocking and locking process to ensure smooth and efficient operation.

[0009] The specific technical solution adopted by this invention is as follows:

[0010] A quick-release tractor saddle, comprising:

[0011] The system comprises a slide rail frame, a support base, and a traction seat body, wherein the support base is slidably mounted on the slide rail frame, and the traction seat body is detachably connected to the support base by bolts. It also includes:

[0012] A sliding block is disposed on the bottom surface of the support base and is slidably connected to the slide rail frame. The sliding block has a first cavity and a second cavity inside.

[0013] An adjustment mechanism, which is mounted on a sliding block, is used to adjust the position of the traction seat body;

[0014] The adjustment mechanism includes a drive unit, which is fixedly installed on the bottom surface of the support base. The sliding block is provided with a locking part, an oil-taking part, and an applicating part.

[0015] The coating part includes an oil storage tank, which is located at a circular groove. The inner circle of the oil storage tank has spray holes distributed in a ring. An oil scraping ring is fixedly connected to the inner wall of the circular groove. An oil delivery groove is provided on the sliding block to connect the first cavity and the oil storage tank.

[0016] In a preferred embodiment, the slide rail frame has an oil storage cavity, and through slots are arranged in an array on one side of the oil storage cavity. Guide rods are inserted into the slide rail frame in an array on the side away from the through slots, and the number of guide rods corresponds to the number of through slots. A baffle is fixedly connected to one end of the guide rod in the oil storage cavity, and a spring is sleeved on the outer wall of the guide rod. An oil injection head is connected to the slide rail frame and is connected to the oil storage cavity. Locking holes are also arranged in an array on the slide rail frame.

[0017] In a preferred embodiment, the traction seat body is provided with a locking hook and a shock-absorbing seat, and the locking hook is provided with a locking hook oil injection assembly.

[0018] In a preferred embodiment, the locking hook oiling assembly includes an annular oil groove, which is formed on the locking hook. Oil outlet grooves are evenly distributed in the inner circle of the annular oil groove. An oiling pipe is connected to the locking hook and communicates with the annular oil groove.

[0019] In a preferred embodiment, the shock-absorbing seat includes a support leg and a cover plate, the cover plate extending through the support leg, and a first pad provided on the top surface of the cover plate, and a second pad provided at the upper end of the support leg.

[0020] In a preferred embodiment, the drive unit includes an electric push rod, which is fixedly installed on the bottom surface of the support base. Each end of the electric push rod has a stop block fixedly connected to a telescopic rod, and the stop block is slidably inserted into one end of the sliding block and extends into the second cavity.

[0021] In a preferred embodiment, the locking part includes a circular groove formed on the sliding block, a locking rod slidably inserted into the circular groove, a circular ring fixedly sleeved on the outer wall of the locking rod, and a compression spring sleeved on the outer wall of the locking rod.

[0022] In a preferred embodiment, the oil-collecting part includes a round rod connected to one side of the abutment block and piston-likely inserted between the first cavity and the second cavity. The other end of the round rod is fixedly connected to a push plate, which is slidably connected within the first cavity. A holding box is fixedly connected to the other side of the push plate, with one end of the holding box slidably inserted into one side of the sliding block. A feeding plate is rotatably connected to the bottom surface of the holding box, and a limit block is fixedly connected to one side of the push plate.

[0023] A method for securing a towing vehicle saddle, applied to the aforementioned quick-release towing vehicle saddle, includes the following steps:

[0024] Step 1: When it is necessary to adjust the position of the traction seat body, first control the electric push rod to shorten, so that the locking part returns to the initial position. At this time, the sliding block will be released from the limit state and can slide freely.

[0025] Step 2: Adjust the position of the traction seat body to a suitable position;

[0026] Step 3: After adjusting to the desired position, control the electric push rod to extend, so that the locking part fixes the sliding block, ensuring its stability and reliability, and automatically applies lubricating grease to the locking rod during the unlocking and locking process;

[0027] Step 4: When it is necessary to disassemble the entire traction seat body, simply unscrew the bolts connecting the traction seat body and the support seat.

[0028] The technical effects achieved by this invention are as follows:

[0029] This invention incorporates an application unit that, during the movement of the abutment block, drives the movement of the round rod, thereby causing the push plate and the container to move synchronously. The movement of the push plate compresses the lubricating grease in the first cavity, forcing it along the oil delivery groove into the oil storage tank, and finally spraying it out through the spray nozzle. This process ensures the lubricating grease is evenly applied to the locking rod, effectively eliminating the need for manual application.

[0030] This invention, by incorporating an oil-collecting section, allows the oil-retaining box to move into the first cavity during unlocking, as the position of the traction seat body is adjusted. At this time, the baffle loses its original resistance, and the spring generates a restoring force, pushing the baffle back to its original position. The reset baffle effectively seals the passage, ensuring that the lubricating grease in the oil-retaining groove does not leak out. During locking, the oil-collecting box returns from the first cavity to the oil-retaining groove for oil collection. This achieves automatic oil collection during unlocking and locking, eliminating the tedious step of frequent manual oil filling and significantly improving ease of use. Furthermore, this design automatically applies lubricating grease to the locking rod during unlocking and locking, ensuring smooth and efficient operation.

[0031] The locking hook of this invention is equipped with a locking hook lubrication assembly, designed to achieve efficient lubrication. This assembly allows for a smooth connection between the lubrication pipe and an external lubrication line, ensuring that lubricating grease flows accurately into the annular oil groove. Subsequently, the lubricating grease flows out from the outlet groove, directly applying it to the trailer's tow pin, thus achieving a convenient operation without needing to remove the trailer's tow pin from the tow seat body for lubrication.

[0032] Furthermore, the oil filling pipe can also be connected to an oil pump. By periodically starting the oil pump, an appropriate amount of lubricating grease can be automatically added to the annular oil groove, ensuring the continuity and stability of lubrication operations. This design not only improves lubrication efficiency and reduces the tediousness of manual operation, but also ensures that the trailer towing pin receives uniform and sufficient lubrication, thereby extending its service life and improving the overall vehicle's operational safety and stability.

[0061] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0062] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0063] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0064] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0065] Please see the appendix Figure 1 - Figure 17 As shown, this embodiment provides a quick-release tractor saddle, comprising:

[0066] The slide rail frame 1, support base 2, and traction seat body 3 are included. The support base 2 is slidably mounted on the slide rail frame 1, and the traction seat body 3 is detachably connected to the support base 2 by bolts. The system also includes:

[0067] Sliding block 4 is disposed on the bottom surface of support base 2 and is slidably connected to slide rail frame 1. The sliding block 4 has a first cavity 41 and a second cavity 42 inside.

[0068] Adjustment mechanism 5, which is mounted on sliding block 4, is used to adjust the position of traction seat body 3;

[0069] The adjustment mechanism 5 includes a drive unit 51, which is fixedly installed on the bottom surface of the support base 2. The sliding block 4 is provided with a locking part 52, an oil taking part 53, and an application part 54.

[0070] In this embodiment, the drive unit 51 serves as a power source, and its two ends cooperate with the locking unit 52 to achieve precise control of the locking unit 52. The locking unit 52 can cooperate with the corresponding locking position on the slide rail frame 1 to lock and unlock the sliding block 4. The oil-taking unit 53 is used to draw lubricating grease from the oil storage container. The applicating unit 54 is responsible for evenly applying the lubricating grease transmitted from the oil-taking unit 53 to the locking unit 52. During this process, any leaked lubricating grease drips into the track on the slide rail frame 1, which can achieve the purpose of lubricating the slide rail frame 1 and reducing friction and wear.

[0071] When the position of the traction seat body 3 needs to be adjusted, the locking part 52 is first unlocked by the drive unit 51, allowing the support seat 2 and the traction seat body 3 to slide freely on the slide rail 1. Then, the support seat 2 is pushed to slide along the slide rail 1 manually or mechanically to achieve the initial positioning of the traction seat body 3. Finally, the locking part 52 is locked again by the drive unit 51 to fix the traction seat body 3 in the desired position.

[0072] During adjustment, the oil-taking part 53 and the coating part 54 can work synchronously to ensure that the sliding surfaces of the locking part 52 and the slide rail 1 are always lubricated, improving sliding smoothness and service life. In addition, through the precise control of the adjustment mechanism 5, the position of the traction seat body 3 can be finely adjusted to meet the needs of different working scenarios.

[0073] In summary, the components provided in this embodiment, such as the slide rail frame 1, support base 2, traction seat body 3, sliding block 4, and adjustment mechanism 5, through combination and design, achieve precise adjustment and lubrication maintenance of the position of the traction seat body 3, thereby improving work efficiency and service life.

[0074] Secondly, please refer to it again. Figure 1 - Figure 4 The slide rail frame 1 has an oil storage cavity 101. On one side of the oil storage cavity 101, through slots 102 are arranged in an array. On the side of the slide rail frame 1 away from the through slots 102, guide rods 103 are inserted in an array, and the number of guide rods 103 corresponds to the number of through slots 102. One end of the guide rod 103 located in the oil storage cavity 101 is fixedly connected to a baffle 104, and a spring 105 is also sleeved on the outer wall of the guide rod 103. An oil injection head 106 is connected to the slide rail frame 1, and the oil injection head 106 is connected to the oil storage cavity 101. Locking holes 107 are also arranged in an array on the slide rail frame 1.

[0075] In this embodiment, the oil storage cavity 101 allows the slide rail 1 to store a certain amount of lubricating grease during use. The array distribution of the through grooves 102 allows the oil taking part 53 to enter the oil storage cavity 101.

[0076] The baffle 104 prevents lubricating grease from leaking out of the through groove 102, ensuring the sealing of the oil storage cavity 101. The through-hole design of the grease inlet 106 allows users to easily replenish lubricating grease to the oil storage cavity 101 without disassembling the slide rail 1, greatly improving ease of use. The array distribution of the locking holes 107 allows the slide rail 1 to be fixedly connected to the locking part 52, enhancing the stability and reliability of the overall structure.

[0077] Secondly, please refer to Figure 13 The traction seat body 3 is provided with a locking hook 31 and a shock absorber 33, and the locking hook 31 is provided with a locking hook oil injection assembly 32. The locking hook 31 is an essential part of the traction seat body 3. The locking hook 31 is a product in the prior art, and the specific installation method and position will not be described here.

[0078] In this embodiment, the shock-absorbing seat 33 provides a good buffering effect for the traction seat, effectively reducing the vibration and impact that may occur during transportation, and ensuring the stability and safety of the traction seat and its connecting components.

[0079] It is worth mentioning that the design of the locking hook lubrication assembly 32 undoubtedly greatly extends the service life of the locking hook 31. Through regular or irregular lubrication operations, the locking hook lubrication assembly 32 can ensure that the locking hook 31 is always lubricated during operation, thereby avoiding wear and damage caused by friction and greatly extending the service life of the locking hook 31.

[0080] In addition, the traction seat body 3 is a cast traction seat with an uneven surface. This uneven surface can help the entire surface store lubricating grease, which can improve lubrication. Because it is a cast structure, the thickness of each part can be freely designed. Therefore, the cast traction seat can be thickened in the key wear parts, which will result in the cast traction seat having a longer service life than the stamped traction seat. The overall structure is more robust.

[0081] Secondly, please refer to it again. Figure 14 and Figure 15 The locking hook oiling assembly 32 includes an annular oil groove 321, which is formed on the locking hook 31. Oil outlet grooves 322 are evenly distributed in the inner circle of the annular oil groove 321. An oiling pipe 323 is connected to the locking hook 31 and is connected to the annular oil groove 321.

[0082] In this embodiment, a hook lubrication assembly 32 is provided on the hook 31. This assembly is designed to achieve efficient lubrication. Through this assembly, the lubrication pipe 323 can be smoothly connected to an external lubrication pipe, ensuring that the lubricating grease flows accurately into the annular oil groove 321 along the lubrication pipe 323. Subsequently, the lubricating grease flows out from the oil outlet 322 and directly applies it to the trailer tow pin, thus achieving a convenient operation that does not require removing the trailer tow pin from the tow seat body 3 for lubrication.

[0083] Furthermore, the oil injection pipe 323 can also be connected to an oil pump. By periodically starting the oil pump, an appropriate amount of lubricating grease can be automatically added to the annular oil groove 321, ensuring the continuity and stability of lubrication operations. This design not only improves lubrication efficiency and reduces the tediousness of manual operation, but also ensures that the trailer towing pin receives uniform and sufficient lubrication, thereby extending its service life and improving the overall vehicle's operational safety and stability.

[0084] Please refer to it again. Figure 16 and Figure 17 The shock absorber 33 includes a support leg 331 and a cover plate 332. The cover plate 332 passes through the support leg 331, and a first gasket 333 is provided on the top surface of the cover plate 332. A second gasket 334 is provided on the upper end of the support leg 331.

[0085] In this embodiment, the cover plate 332 is placed within the gap of the support leg 331. To enhance structural stability and functionality, a first gasket 333 is specially provided on the surface of the cover plate 332. Simultaneously, a second gasket 334 is also provided at the corresponding position on the support leg 331, ensuring close contact between the first gasket 333 and the second gasket 334 to achieve a shock-absorbing effect. This effectively reduces the impact of instantaneous pressure on the traction seat body 3 and lowers the pressure exerted on the traction seat body 3 by the trailer.

[0086] During installation, bolts were used to secure the shock absorber 33 to the traction seat body 3, ensuring a tight fit between the cover plate 332 and the traction seat body 3. Simultaneously, the support leg 331 was also connected to the support seat 2 via bolts to ensure the stability and reliability of the entire structure.

[0087] Please refer to it again. Figure 6 The drive unit 51 includes an electric push rod 511, which is fixedly installed on the bottom surface of the support base 2. Each end of the electric push rod 511 has a stop block 512 fixedly connected to a telescopic rod, and the stop block 512 is slidably inserted into one end of the sliding block 4 and extends into the second cavity 42.

[0088] In this embodiment, the sliding blocks 4 on both sides of the support base 2 are slidably connected to the slide rail frame 1. Moving the support base 2, thereby moving the traction seat body 3. Before initiating the movement, the electric push rod 511 must be shortened to return the locking part 52 to its initial position. At this time, the sliding block 4 will be released from its limiting state and can slide freely. After the sliding block 4 moves and adjusts the traction seat body 3 to the required position, the electric push rod 511 is extended again to fix the locking part 52 to the sliding block 4, ensuring its stability and reliability.

[0089] Please refer to it again. Figure 7 - Figure 10 The locking part 52 includes a circular groove 521, which is formed on the sliding block 4. A locking rod 522 is slidably inserted into the circular groove 521. A circular ring 523 is fixedly sleeved on the outer wall of the locking rod 522. A compression spring 524 is also sleeved on the outer wall of the locking rod 522.

[0090] In this embodiment, when unlocking is required, the electric push rod 511 is first controlled to shorten and reset the stop block 512. During the reset of the stop block 512, the locking rod 522 gradually loses its resisting force. At this time, the compression spring 524 will activate, pushing the ring 523 to reset the locking rod 522. Subsequently, the locking rod 522 will disengage from the lock hole 107, thereby causing the sliding block 4 to lose its limiting state. At this point, the position of the traction seat body 3 on the support base 2 can be adjusted.

[0091] When locking is required, the electric push rod 511 should be extended, thereby moving the stop block 512. As the stop block 512 moves, it will gradually apply a resisting force to the locking rod 522, causing the locking rod 522 to move outward and eventually insert into the locking hole 107 on the slide rail 1, achieving the locked state. At this time, the sliding block 4 will be unable to move.

[0092] Please refer to it again. Figure 9 and Figure 10 The oil-taking part 53 includes a round rod 531, which is connected to one side of the abutment block 512 and is piston-like inserted between the first cavity 41 and the second cavity 42. The other end of the round rod 531 is fixedly connected to a push plate 532, which is slidably connected in the first cavity 41. The other side of the push plate 532 is fixedly connected to a container 533, and one end of the container 533 is slidably inserted into one side of the sliding block 4. The bottom surface of the container 533 is rotatably connected to a feeding plate 534, and a limit block 535 is fixedly connected to one side of the push plate 532.

[0093] In this embodiment, during the resetting process of the abutment block 512, it moves the container 533 from the oil storage cavity 101 on the slide rail frame 1 to the first cavity 41 on the sliding block 4 via the round rod 531. When the stroke ends, most of the container 533 will be located in the first cavity 41. At this time, the feed plate 534 rotates downward due to the loss of contact at the slot of the sliding block 4. Subsequently, the lubricating grease inside the container 533 will flow out through the opening and enter the first cavity 41. During this process, the limiting block 535 is designed to limit the rotation angle of the feed plate 534 to ensure that the container 533 maintains a certain distance from the bottom of the first cavity 41, thereby facilitating the complete outflow of the lubricating grease inside the container 533.

[0094] As the container 533 moves towards the oil storage chamber 101, it slides along the slot on the sliding block 4. Subsequently, the feed plate 534 rotates upwards upon contact, closing the opening at the bottom of the container 533 to prevent lubricating grease from flowing out. When the container 533 moves onto the slide rail 1, it contacts the baffle 104, causing the baffle 104 to move. The movement of the baffle 104 further drives the guide rod 103 to move along the slide rail 1, compressing the spring 105. After the container 533 enters the oil storage chamber 101 on the slide rail 1, the lubricating grease inside the oil storage chamber 101 flows into the container 533 through the opening at the top, thus achieving automatic oil dispensing. This design effectively transfers the lubricating grease inside the oil storage tank to the first cavity 41, facilitating the application of lubricating grease to the locking rod 522.

[0095] During the adjustment of the position of the traction seat body 3, when unlocking, the storage box 533 moves the self-storage oil chamber 101 into the first cavity 41. At this time, the baffle 104 loses its original resistance, and the spring 105 immediately generates a restoring force, pushing the baffle 104 to reset. After resetting, the baffle 104 will effectively block the through groove 102, ensuring that the lubricating grease in the storage chamber 101 will not flow out.

[0096] During the locking process, the container 533 returns from the first cavity 41 to the oil storage cavity 101 for oil dispensing. This achieves automatic oil dispensing during unlocking and locking, eliminating the tedious step of frequent manual oil filling and significantly improving ease of use. Simultaneously, this design automatically applies lubricating grease to the locking lever 522 during unlocking and locking, ensuring smooth and efficient operation.

[0097] Please refer to it again. Figure 11 and Figure 12 The coating part 54 includes an oil storage tank 541, which is located at the circular groove 521. The inner circle of the oil storage tank 541 is provided with oil spray holes 542 arranged in a ring. An oil scraper ring 543 is fixedly connected to the inner wall of the circular groove 521. An oil delivery groove 544 is provided on the sliding block 4 to connect the first cavity 41 and the oil storage tank 541.

[0098] In this embodiment, during the movement of the abutment block 512, its movement also drives the movement of the round rod 531, thereby causing the push plate 532 and the container 533 to move synchronously. The movement of the push plate 532 will squeeze the lubricating grease in the first cavity 41, causing the lubricating grease to be squeezed along the oil delivery groove 544 into the oil storage groove 541, and finally sprayed out through the oil spray hole 542. During this process, the lubricating grease can be evenly applied to the locking rod 522, effectively saving the step of manual application.

[0099] The oil scraper ring 543 is designed to scrape off the lubricating grease on the locking rod 522 when the locking rod 522 is reset.

[0100] A method for securing a towing vehicle saddle, applied to the aforementioned quick-release towing vehicle saddle, includes the following steps:

[0101] Step 1: When it is necessary to adjust the position of the traction seat body 3, first control the electric push rod 511 to shorten, so that the locking part 52 returns to the initial position. At this time, the sliding block 4 will be released from the limit state and can slide freely.

[0102] Step 2: Adjust the position of the traction seat body 3 to a suitable position;

[0103] Step 3: After adjusting to the desired position, control the electric push rod 511 to extend, so that the locking part 52 fixes the sliding block 4, ensuring its stability and reliability, and automatically applies lubricating grease to the locking rod 522 during the unlocking and locking process;

[0104] Step 4: When it is necessary to disassemble the entire traction seat body 3, simply unscrew the bolts connecting the traction seat body 3 and the support seat 2.

[0105] The working principle of this invention is as follows:

[0106] When connecting the towing unit to the trailer, first unlock the safety lock on the towing unit body 3, then pull out the lever. After pulling out, the lever is about 36 centimeters long, so that the towing unit is in a pre-engaged state. Then align the center of the towing unit with the center of the trailer's towing pin, and slowly drive the tractor into the trailer to connect. After the connection is complete, reset the lever and lock it with the safety lock (how the towing unit connects to the trailer is a publicly available operating procedure and will not be described in detail here).

[0107] The sliding blocks 4 on both sides of the support base 2 are slidably connected to the slide rail frame 1. Moving the support base 2, in turn, moves the traction seat body 3. Before initiating the movement, the electric push rod 511 must be shortened to return the locking part 52 to its initial position. At this time, the sliding block 4 will be released from its limiting state and can slide freely. After the sliding block 4 moves and adjusts the traction seat body 3 to the required position, the electric push rod 511 is extended again to fix the locking part 52 to the sliding block 4, ensuring its stability and reliability.

[0108] Specifically:

[0109] When unlocking is required, the electric push rod 511 must first be controlled to shorten and reset the stop block 512. During the reset of the stop block 512, the locking rod 522 gradually loses its resisting force. At this time, the compression spring 524 will activate, pushing the ring 523 to reset the locking rod 522. Subsequently, the locking rod 522 will disengage from the lock hole 107, thereby causing the sliding block 4 to lose its limiting state. At this point, the position of the traction seat body 3 on the support base 2 can be adjusted.

[0110] During the resetting process of the abutment block 512, it moves the container 533 from the oil storage cavity 101 on the slide rail frame 1 to the first cavity 41 on the sliding block 4 via the round rod 531. When the stroke ends, most of the container 533 will be located in the first cavity 41. At this time, the feed plate 534 rotates downward due to the loss of contact at the slot of the sliding block 4. Subsequently, the lubricating grease inside the container 533 will flow out through the opening and enter the first cavity 41. During this process, the limiting block 535 is designed to limit the rotation angle of the feed plate 534 to ensure that the container 533 maintains a certain distance from the bottom of the first cavity 41, thereby facilitating the complete outflow of the lubricating grease inside the container 533.

[0111] When locking is required, the electric push rod 511 should be extended, thereby moving the stop block 512. As the stop block 512 moves, it will gradually apply a resisting force to the locking rod 522, causing the locking rod 522 to move outward and eventually insert into the lock hole 107 on the slide rail 1, achieving the locked state. At this time, the sliding block 4 will be unable to move.

[0112] During the movement of the abutment block 512, its movement also drives the movement of the round rod 531, thereby causing the push plate 532 and the container 533 to move synchronously. The movement of the push plate 532 will squeeze the lubricating grease in the first cavity 41, causing the lubricating grease to be squeezed into the oil storage tank 541 along the oil delivery groove 544, and finally sprayed out through the oil spray hole 542. In this process, the lubricating grease can be evenly applied to the locking rod 522, effectively saving the step of manual application.

[0113] Simultaneously, the container 533 slides along the slot on the sliding block 4 during its movement. Subsequently, the feed plate 534 rotates upward upon contact, thereby closing the opening at the bottom of the container 533 and preventing lubricating grease from flowing out. When the container 533 moves onto the slide rail 1, it abuts against the baffle 104, causing the baffle 104 to move. The movement of the baffle 104 further drives the guide rod 103 to move along the slide rail 1 and compresses the spring 105. When the container 533 enters the oil storage chamber 101 on the slide rail 1, the lubricating grease inside the oil storage chamber 101 flows into the container 533 through the opening at the top of the container 533, thereby achieving automatic oil dispensing. This design effectively transfers the lubricating grease inside the oil storage tank to the first cavity 41, facilitating the application of lubricating grease to the locking rod 522.

[0114] During the adjustment of the position of the traction seat body 3, when unlocking, the storage box 533 moves the self-storage oil chamber 101 into the first cavity 41. At this time, the baffle 104 loses its original resistance, and the spring 105 immediately generates a restoring force, pushing the baffle 104 to reset. After resetting, the baffle 104 will effectively block the through groove 102, ensuring that the lubricating grease in the storage chamber 101 will not flow out.

[0115] During the locking process, the container 533 returns from the first cavity 41 to the oil storage cavity 101 for oil dispensing. This achieves automatic oil dispensing during unlocking and locking, eliminating the tedious step of frequent manual oil filling and significantly improving ease of use. Simultaneously, this design automatically applies lubricating grease to the locking lever 522 during unlocking and locking, ensuring smooth and efficient operation.

[0116] The hook 31 is equipped with a hook lubrication assembly 32, designed for efficient lubrication. This assembly allows for a smooth connection between the lubrication pipe 323 and an external lubrication line, ensuring accurate flow of lubricating grease into the annular oil groove 321. The lubricating grease then flows out from the outlet groove 322, directly applying it to the trailer's tow pin, thus eliminating the need to remove the trailer's tow pin from the tow seat body 3 for lubrication.

[0117] Furthermore, the oil injection pipe 323 can also be connected to an oil pump. By periodically starting the oil pump, an appropriate amount of lubricating grease can be automatically added to the annular oil groove 321, ensuring the continuity and stability of lubrication operations. This design not only improves lubrication efficiency and reduces the tediousness of manual operation, but also ensures that the trailer towing pin receives uniform and sufficient lubrication, thereby extending its service life and improving the overall vehicle's operational safety and stability.

[0118] The cover plate 332 is precisely positioned within the gap of the support leg 331. To enhance structural stability and functionality, a first gasket 333 is specially provided on the surface of the cover plate 332. Simultaneously, a second gasket 334 is also provided at the corresponding position on the support leg 331, ensuring close contact between the first gasket 333 and the second gasket 334 to achieve a shock-absorbing effect. This effectively reduces the impact of instantaneous pressure on the towing seat body 3 and lowers the pressure exerted on the towing seat body 3 by the trailer.

[0119] During installation, bolts were used to secure the shock absorber 33 to the traction seat body 3, ensuring a tight fit between the cover plate 332 and the traction seat body 3. Simultaneously, the support leg 331 was also connected to the support seat 2 via bolts to ensure the stability and reliability of the entire structure.

[0120] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
