[0022] The following is for reference. Figures 1-3According to an embodiment of the present invention, a spare tire lifter assembly 100 is described, wherein a protective tube assembly 2 is detachably connected to a spare tire fixing block 1. The upper inner circumference of the protective tube assembly 2 is provided with a buffer material. After the wire rope 3 passes through the protective tube assembly 2, the swaying of the spare tire causes the wire rope 3 to contact the buffer material on the upper inner circumference of the protective tube assembly 2, thereby reducing the risk of wear on the wire rope 3 and improving the reliability and safety of the spare tire connection.

[0023] like Figure 1-3 As shown, a spare tire lifter assembly 100 according to an embodiment of the present invention includes: a spare tire fixing block 1, a protective tube assembly 2, a steel wire rope 3, and a rope fixing rod 4.

[0024] The spare tire fixing block 1 is movably connected to an upwardly extending protective tube assembly 2. The spare tire fixing block 1 is used to fix the spare tire. The inner circumference of the upper part of the protective tube assembly 2 is provided with cushioning material. The steel wire rope 3 passes through the protective tube assembly 2 and is adapted to contact the cushioning material when swaying. The rope fixing rod 4 is connected to the bottom of the steel wire rope 3 and extends at least partially into the protective tube assembly 2.

[0025] In practice, spare tire lifters are typically specialized accessories installed on the vehicle chassis, primarily using a wire rope or chain transmission mechanism to raise and lower the spare tire. The spare tire mounting block is used to support and secure the vehicle's spare tire, such as... Figure 2 As shown, the top of the spare tire mounting block 1 is provided with a mounting hole 11. The protective tube assembly 2 extends from bottom to top into the mounting hole 11 and is detachably connected to the spare tire mounting block 1. The detachable connection can be made by means of threaded connection or other limiting connection. When the vehicle's spare tire is installed on the spare tire mounting block 1, the weight of the spare tire has a downward force on the spare tire mounting block 1, thereby allowing the protective tube assembly 2 to have an upward force that presses against the spare tire mounting block 1.

[0026] Reference Figure 1 As shown, the upper part of the spare tire fixing block 1 is also provided with a lifting body 6. The lifting body 6 generally includes an unwinding part 61 and a lifting mechanism connected to the unwinding part 61. The wire rope 3 is wound around the unwinding part 61. The rotation of the unwinding part 61 is controlled by the lifting mechanism, thereby controlling the lifting of the wire rope 3. That is, one end of the wire rope 3 is movably connected to the unwinding part 61 and the other end is connected to the spare tire fixing block 1. If the protective tube assembly 2 is provided with a through hole, the wire rope 3 passes through the through hole and passes through the protective tube assembly 2. The bottom of the wire rope 3 is fixed by the rope fixing rod 4. The rope fixing rod 4 can limit the bottom of the wire rope 3 and protect the bottom of the wire rope 3.

[0027] The steel wire rope 3 passes through the protective tube assembly 2. The upper inner circumferential wall of the protective tube assembly 2 is provided with a cushioning material. Generally, there is a gap between the outer circumference of the steel wire rope 3 and the inner circumference of the cushioning material. For example, the gap between the outer circumference of the steel wire rope 3 and the inner circumferential wall of the cushioning material can be 0.5mm-1mm, such as 0.5mm, 0.6mm, 0.7mm, etc., which facilitates the installation of the steel wire rope 3 and the protective tube assembly 2, and also facilitates the up and down movement of the steel wire rope 3 along the protective tube assembly 2, thereby facilitating the removal of the spare tire. When the vehicle is moving or vibrating, the steel wire rope 3 will shake. When the steel wire rope 3 shakes, it will come into contact with and press against the cushioning material on the upper inner circumference of the protective tube assembly 2. The cushioning material can be made of nylon or high-hardness rubber, etc., thereby reducing the wear between the steel wire rope 3 and the protective tube assembly 2, improving the safety of the steel wire rope 3, and at the same time preventing the steel wire rope 3 from pressing too hard against the cushioning material, which would reduce the life of the cushioning material.

[0028] In addition, after the rope fixing rod 4 is connected to the wire rope 3 and passes through the bottom inner circumference of the protective tube assembly 2, the part of the wire rope 3 above the rope fixing rod 4 and connected to the protective tube assembly 2 can be kept taut. Therefore, even if the spare tire shakes, the wire rope 3 connected to the rope fixing rod 4 and the wire rope 3 located in the protective tube assembly 2 are basically kept taut, which can reduce the shaking of the wire rope 3, thereby reducing the friction between the wire rope 3 and the surrounding structure, improving the service life of the wire rope 3, and thus improving the reliability and safety of the wire rope 3 in fixing the spare tire.

[0029] In some embodiments, the protective tube assembly 2 includes a protective tube 21 and a protective sleeve 22. The protective sleeve 22 is constructed as a cushioning material. The protective tube 21 is movably connected to the spare tire fixing block 1, and the protective sleeve 22 is located on the upper inner periphery of the protective tube 21.

[0030] Specifically, refer to Figure 2As shown, the protective tube 21 extends upwards along the mounting hole 11 of the spare tire fixing block 1. A protective sleeve 22 is provided on the upper inner circumference of the protective tube 21. The protective sleeve 22 can be press-fitted into place with the protective tube 21 using an interference fit. This press-fitting process simplifies the complex steps of traditional welding or threaded connections, reducing installation costs and time. Furthermore, the press-fitting method prevents the cushioning material from loosening due to external environmental influences. Alternatively, the protective tube 21 and the protective sleeve 22 can be connected as a single unit using other methods, such as having a wall thickness less than that of the protective tube 21. The protective tube 21 serves as a fixation and protection for the steel wire rope 3 connecting to the spare tire fixing block 1, improving the reliability, stability, and safety of the connection. Moreover, by setting the protective tube assembly 2 to include both the protective tube 21 and the protective sleeve 22 for press-fitting, the inner circumference of the protective tube 21 can be selectively press-fitted according to the required length and thickness of the protective sleeve 22, increasing the flexibility of the protective tube assembly 2.

[0031] In addition, the inner circumference of the top of the protective sleeve 22 is provided with a chamfer structure 221. The lower part of the chamfer structure 221 is closer to the wire rope 3, and the upper part is farther away from the wire rope 3. That is, the setting of the chamfer structure 221 is equivalent to widening the opening of the upper inner circumference of the protective sleeve 22. At the same time, it also avoids the problem of force concentration when the wire rope 3 contacts and presses against the top of the protective sleeve 22, reducing the wear on the wire rope 3. Furthermore, the chamfer structure 221 can be set as an arc-shaped chamfer, thereby further reducing the phenomenon of force concentration.

[0032] Of course, a chamfered structure 221 can also be provided on the lower inner circumference of the protective sleeve 22. The bottom of the chamfered structure 221 on the lower inner circumference of the protective sleeve 22 is far away from the wire rope 3, and the upper part is close to the wire rope 3. The chamfered structure 221 can be set as an arc shape, which can reduce the wear between the wire rope 3 and the lower end of the protective sleeve 22. At the same time, this chamfered structure 221 at the lower part of the protective sleeve 22 also makes it easier for the wire rope 3 to pass through the through hole of the protective sleeve 22 for installation.

[0033] It should also be noted that the axial length of the protective sleeve 22 can be 1 / 3 of the axial length of the protective tube 21. Alternatively, the axial length of the protective sleeve 22 can be set to 1 / 4 of the axial length of the protective tube 21. This can separate the top of the wire rope 3 from the protective tube 21, reduce wear on the wire rope 3, and reduce the material used in the protective sleeve 22.

[0034] In some embodiments, the protective tube 21 is made of metal, and the protective sleeve 22 is made of nylon. The protective tube 21 is made of metal, such as steel, which has excellent tensile strength, compressive strength, and corrosion resistance. Steel also has high temperature and abrasion resistance, and can stably fix the direction of the wire rope 3, preventing excessive wear or deformation. Alternatively, the protective tube 21 can be made of other metal materials with good strength to improve the strength at the connection between the wire rope 3 and the spare tire fixing block 1.

[0035] In addition, the protective sleeve 22 can be made of nylon material. Nylon, scientifically known as polyamide (PA), is a general term for thermoplastic resins with repeating amide groups in the main chain. It is mostly white or light yellow granules in appearance. It can be obtained by ring-opening polymerization of lactam or condensation reaction of diamine and diacid. Common varieties include nylon 6 (PA6) and nylon 66 (PA66). The core advantages of nylon are its excellent mechanical properties, good wear resistance, low coefficient of friction, and self-lubricating properties. In other words, by making the protective sleeve 22 of nylon material, the protective sleeve 22 can have extremely high mechanical strength and wear resistance, as well as good toughness and impact resistance, so that it can better withstand high loads and frequent friction. During the swinging process, the steel wire rope 3 will frequently rub against the protective sleeve 22. Therefore, the protective sleeve 22 made of nylon material can better resist the frequent friction of the steel wire rope 3 and improve the service life of the steel wire rope 3.

[0036] In other words, if the protective sleeve 22 is not equipped with a cushioning material, the steel wire rope 3 may come into contact with the metal protective tube 21 when the vehicle vibrates. Furthermore, the metal protective tube 21 has high hardness and a relatively sharp end. During repeated shaking, the steel wire rope 3 will experience stress concentration and repeated wear, reducing its lifespan. Therefore, by setting a nylon protective sleeve 22 on the upper inner circumference of the protective tube 21, the wear of the steel wire rope 3 can be reduced. At the same time, the nylon protective sleeve 22 also reduces the problem of reduced lifespan or even breakage of the steel wire rope 3 due to repeated friction.

[0037] In some embodiments, the sum of the axial length of the protective sleeve 22 and the length of the rope fixing rod 4 extending into the protective tube 21 is more than 1 / 2 of the length of the protective tube 21.

[0038] Continue to refer to Figure 2As shown, the wire rope 3 is located in the upper part of the protective tube 21 and can contact the protective sleeve 22 when swaying. Its lower part is fixed by the rope fixing rod 4. If the sum of the length of the rope fixing rod 4 extending into the protective tube 21 and the axial length of the protective sleeve 22 is 3 / 4 or 3 / 5 of the length of the protective tube 21, then the wire rope 3 is essentially in a taut state within the protective tube 21. If the portion between the top of the protective sleeve 22 and the top of the rope fixing rod 4 is taut, it improves the stability of the wire rope 3 at this point, reduces swaying, and thus improves the stability of the spare tire installation. Furthermore, when the wire rope 3 is more stable, the frictional force between the wire rope 3 and the protective sleeve 22 is reduced, thereby increasing the service life and reliability of the wire rope 3. Alternatively, the length of the rope fixing rod 4 extending into the protective tube 21 can be set to less than 1 / 2 of the length of the protective tube 21 to improve the ease of connection of the rope fixing rod 4. It is only necessary to ensure that the sum of the axial length of the protective sleeve 22 and the length of the rope fixing rod 4 extending into the protective tube 21 is more than 1 / 2 of the length of the protective tube 21, so that the wire rope 3 is in a taut state.

[0039] The steel wire rope 3 is protected by both the protective sleeve 22 and the rope fixing rod 4, which improves the protection effect of the steel wire rope 3 and also increases the tension of the steel wire rope 3, so as to achieve effective pulling of the spare tire by the steel wire rope 3.

[0040] In some embodiments, a gap is left between the portion of the rope fixing rod 4 that extends into the protective tube 21 and the inner circumference of the protective tube 21. Specifically, after the wire rope 3 passes through the protective sleeve 22, the gap between the rope fixing rod 4 and the protective tube 21 can be 0.5mm-1mm, such as 0.5mm, 0.6mm, 0.8mm, etc. After the spare tire is connected to the spare tire fixing block 1, the weight of the spare tire can make the spare tire fixing block 1 move downward as a whole, which is equivalent to making the rope fixing rod 4 move upward inside the protective tube 21 until it stops moving upward. The gap between the outer circumference of the rope fixing rod 4 and the inner circumference of the protective tube 21 facilitates the connection between the rope fixing rod 4 and the wire rope 3, and allows the rope fixing rod 4 to move upward after the spare tire is installed, which is equivalent to the spare tire fixing block 1 finally tightening the wire rope 3. The rope fixing rod 4 can be used to fix and protect the wire rope 3. That is, the setting of the gap between the rope fixing rod 4 and the protective tube 21 can improve the flexibility of installing the detachable spare tire.

[0041] In some embodiments, the spare tire lifter assembly 100 further includes an elastic element 5, which is sleeved on the wire rope 3, and the rope fixing rod 4 extends through the inner circumference of the elastic element 5 into the protective tube 21, and the elastic element 5 abuts against the bottom of the protective tube 21.

[0042] Among them, the elastic element 5 can be a spring. The spring in the spare tire lifter assembly 100 usually has functions such as high stiffness and overload protection to ensure the safety and stability of the lifting process. For example, the longitudinal stiffness of the spring can reach 300N / mm, which can effectively support the load during the lifting process and reduce deformation.

[0043] In actual installation, firstly, the protective sleeve 22 and the protective tube 21 are press-fitted together and installed in place. Then, the protective tube assembly 2, formed by the combination of the protective tube 21 and the protective sleeve 22, is inserted into the mounting hole 11 in the center of the spare tire fixing block 1 and connected. Then, the spring is inserted into the wire rope 3, so that the wire rope 3 passes through the protective sleeve 22 of the protective tube assembly 2. Finally, the rope fixing rod 4 is riveted and fixed to the bottom end of the wire rope 3. The rope fixing rod 4 includes a main body 41 and a second limiting part 42 connected to the bottom of the main body 41. The second limiting part 42 is a metal plate that extends radially along the lower end of the main body 41, thereby limiting and pressing the spring. The spare tire fixing block 1 is connected to the spare tire, and the spring is compressed so that the bottom of the spring is limited by the metal plate and the top presses against the bottom of the protective tube 21. By setting the spring, the impact force of the wire rope 3 can be absorbed during the lifting process, reducing the damage of mechanical vibration to the spare tire, and improving the stability of operation.

[0044] Furthermore, the wall thickness of the bottom of the main body 41 and the second limiting part 42 can be set to be greater than the wall thickness of other parts of the main body 41, which is equivalent to strengthening the connection between the main body 41 and the second limiting part 42. This results in higher structural strength at the bottom of the wire rope 3, thereby effectively fixing and limiting the bottom of the wire rope 3 and improving the strength of the connection between the rope fixing rod 4 and the bottom of the wire rope 3.

[0045] Furthermore, the rope fixing rod 4 is riveted to the bottom end of the wire rope 3. The riveting fixation is achieved through a cold extrusion process using aluminum alloy or low-carbon steel sleeves, forming a gapless integral structure between the wire rope 3 and the rope fixing rod 4. The contact between the wire rope 3 and the rope fixing rod 4 is a surface contact, and the load capacity can reach 90% of the breaking strength of the wire rope 3. The riveting fixation reduces the loss problems such as the reduction of the wire rope diameter and the accumulation of broken wires in the wire rope 3. Moreover, the riveting fixation method between the rope fixing rod 4 and the wire rope 3 has advantages such as compact structure, high load-bearing capacity, and strong fatigue resistance, which can effectively improve the stability and safety of the connection part.

[0046] In some embodiments, the upper inner circumference of the protective tube 21 is provided with a groove structure 211, and the protective sleeve 22 is pressed onto the groove structure 211.

[0047] Specifically, the protective sleeve 22 is pressed onto the groove structure 211 on the inner circumference of the upper part of the protective tube 21. Therefore, the upper part of the protective tube 21 can be made thinner, saving material in the upper part of the protective tube 21. If the length of the groove structure 211 along the axial direction is longer than the length of the protective sleeve 22 along the axial direction, it is convenient to install protective sleeves 22 of different lengths. In addition, the setting of the groove structure 211 provides a larger space for the installation of the protective sleeve 22, which facilitates the installation of the protective sleeve 22 and the protective tube 21. That is, after the protective sleeve 22 and the protective tube 21 are installed, the integration of the protective sleeve 22 and the protective tube 21 can be improved, and space is also left for the wire rope 3 to be threaded.

[0048] However, the wall thickness of the protective sleeve 22 can generally be set thinner than that of the protective tube 21. The protective tube 21 serves as the main strength support, while the protective sleeve 22 serves as a buffer material that separates the protective tube 21 from the wire rope 3. It can be set shorter or thinner, which can buffer the contact part between the wire rope 3 and the upper end of the protective tube assembly 2 while saving the material of the protective sleeve 22, and at the same time better protect the wire rope 3.

[0049] In some embodiments, the bottom of the protective tube assembly 2 is provided with a first limiting portion 213 extending radially, the spare tire fixing block 1 is provided with a mounting hole 11, the protective tube assembly 2 passes through the mounting hole 11 and the first limiting portion 213 presses against the spare tire fixing block 1.

[0050] Reference Figure 2 As shown, the bottom of the protective tube 21 is provided with a radially extending first limiting part 213. The first limiting part 213 can be a limiting plate. When the protective tube assembly 2 passes through the mounting hole 11, as the spare tire fixing block 1 moves downward under the action of the spare tire, the limiting plate and the spare tire fixing block 1 press against each other to limit the movement. The thickness of the limiting plate can be greater than the wall thickness of the spare tire fixing block 1, thereby improving the strength and reliability of the limiting of the protective tube assembly 2 and the spare tire fixing block 1 at the mounting hole 11 and improving the support effect of the protective tube 21. By inserting the protective tube assembly 2 into the mounting hole 11 and limiting it through the first limiting part 213, the installation connection between the protective tube assembly 2 and the spare tire fixing block 1 can be achieved, making the overall operation convenient.

[0051] Furthermore, one end of the spring presses against the bottom of the first limiting part 213, meaning the spring is compressed between the first limiting part 213 and the second limiting part 42. When vibration occurs during vehicle operation, causing the spare tire's position to change, the spring can effectively absorb the impact and vibration. Moreover, the diameter of the first limiting part 213 is greater than the radial length of the spring, thus effectively pressing the spring and maintaining uniform force on it. In addition, the bottom of the first limiting part 213 is provided with a circumferential guide slope 212, which gradually approaches the wire rope 3 from the bottom to the top, making it easier for the rope fixing rod 4 to connect to the wire rope 3 and then pass through the lower part of the protective tube 21.

[0052] In some embodiments, the spare tire fixing block 1 is provided with an arc-shaped positioning groove 12, and the rope fixing rod 4 and the protective tube assembly 2 are both located at the arc-shaped positioning groove 12.

[0053] Continue to refer to Figure 2 As shown, the spare tire fixing block 1 has a bowl-shaped cross-section. The center of the bowl-shaped structure has an arc-shaped positioning groove 12, and the top of the arc-shaped positioning groove 12 has a mounting hole 11. This allows the protective tube assembly 2 to be quickly positioned within the arc-shaped positioning groove 12 during installation, and further facilitates its insertion into the mounting hole 11. After the protective tube assembly 2 is inserted into the mounting hole 11, it is located inside the arc-shaped positioning groove 12 of the bowl-shaped structure, providing better protection for the protective tube assembly 2, improving its service life, and reducing the impact of the external environment on it. Furthermore, from... Figure 1 From the perspective of the spare tire fixing block 1, the arc-shaped positioning groove 12 is constructed as an arch structure. The arch structure of the spare tire fixing block 1 can improve the structural strength, has a better ability to resist external impact, and reduce the deformation of the spare tire fixing block 1, thereby improving the reliability of the spare tire connection.

[0054] This utility model embodiment discloses a vehicle including the aforementioned spare tire lifter assembly 100. The steel wire rope 3 is configured to directly contact a cushioning material with buffering performance, avoiding direct contact between the steel wire rope 3 and metal materials, thereby protecting the steel wire rope 3, preventing wear and breakage of the steel wire rope 3, improving the durability of the steel wire rope 3, and thus improving the reliability and safety of the spare tire connection.
