For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0033] Reference is made below Figures 1-6 The guide rod assembly 100 of the tailgate support structure according to an embodiment of the present application is described, the guide rod 2 can be telescopic relative to the guide tube 1, and the outer peripheral wall of the guide rod 2 and the inner peripheral wall of the guide tube 1 are provided with a vibration absorbing member 21, which can reduce the collision sound during the movement of the guide rod 2 and absorb the vibration.
[0034] As Figures 1-6 shown, the guide rod assembly 100 of the tailgate support structure according to an embodiment of the present application comprises: a guide tube 1 and a guide rod 2.
[0035] Among them, at least part of the guide rod 2 is movably connected in the guide tube 1 and can be telescopic relative to the guide tube 1; the outer peripheral wall of the guide rod 2 and the inner peripheral wall of the guide tube 1 are provided with a vibration absorbing member 21, the vibration absorbing member 21 is arranged to be connected to one of the guide rod 2 and the guide tube 1 and axially movable relative to the other.
[0036] In practice, the guide rod 2 partially extends into the guide tube 1 and can be lengthened or contracted relative to the guide tube 1. A vibration absorbing member 21 can be arranged between the outer periphery of the guide rod 2 and the inner peripheral wall of the guide tube 1. For example, the vibration absorbing member 21 can be sleeved on the outer periphery of the guide rod 2 and is axially fixed relative to the guide rod 2. When the guide rod 2 moves, the vibration absorbing member 21 can move relative to the guide tube 1, and the vibration absorbing member 21 can be pressed against the inner peripheral wall of the guide tube 1. The vibration absorbing member 21 can be made of a material with elasticity or a cushioning material. When the guide rod 2 moves relative to the guide tube 1, the vibration absorbing member 21 can have a cushioning force between the vibration absorbing member 21 and the inner peripheral wall of the guide tube 1, thereby reducing the impact between the guide rod 2 and the guide tube 1 and absorbing the vibration force between the guide rod 2 and the guide tube 1.
[0037] Alternatively, the vibration absorbing member 21 can be fixed to the inner peripheral wall of the guide tube 1 and can be pulled to move the guide tube 1 relative to the guide rod 2, thereby absorbing the vibration force. The vibration absorbing member 21 can be arranged at the end of the guide rod 2 or near the end of the guide rod 2. In general, the vibration absorbing member 21 is arranged at the outer periphery of the end of the guide rod 2. When the guide rod 2 is pulled, the force between the guide rod 2 and the guide tube 1 is mainly concentrated between the end of the guide rod 2 and the guide tube 1, thereby facilitating control of the force of the guide rod 2 and facilitating control of the length of the guide rod 2 by the corresponding force.
[0038] Therefore, the vibration absorbing member 21 can reduce the impact sound and absorb the vibration during movement of the guide rod 2.
[0039] In some embodiments, the vibration absorbing member 21 is connected to the guide rod 2 and can move axially relative to the guide tube 1. The vibration absorbing member 21 is axially fixed relative to the guide rod 2 and can rotate circumferentially.
[0040] In practice, when the guide rod assembly 100 changes from the contracted state to the lengthened state, the vibration absorbing member 21 can slide and rub against the guide rod 2 during the change. The vibration absorbing member 21 can rotate freely. The contact position between the vibration absorbing member 21 and the guide tube 1 can change during the rubbing process, thereby ensuring that the vibration is absorbed and the guide rod 2 can move smoothly.
[0041] In some embodiments, the vibration-absorbing component 21 is made of flocked plastic material. Plastic flocking refers to a product made of plastic using a special process, resulting in a cotton-like texture and feel. The raw materials for plastic flocking mainly include synthetic fiber materials such as polyester, nylon, and acrylic. These synthetic fiber materials have excellent wear resistance, light resistance, tear resistance, and elasticity. Due to its special coating and flocked structure, when the flocked plastic material is fitted around the outer periphery of the guide rod 2, the flock can contact the inner wall of the guide tube 1, thereby effectively absorbing sound waves and reducing vibration.
[0042] In addition, the guide tube 1 contains lubricating oil, and the flocked plastic material's fluffy structure can absorb the grease. The grease can adhere to the surface of the flocked layer, which is equivalent to having an oil storage effect. This can reduce the friction between the guide rod 2 and the guide tube 1 when they move, making the movement smoother and reducing vibration or noise caused by friction.
[0043] In some embodiments, the end of the guide rod 2 further includes an axially distributed first limiting portion 22 and a second limiting portion 23, and the vibration absorbing member 21 is disposed between the first limiting portion 22 and the second limiting portion 23 and presses against the inner wall of the guide tube 1.
[0044] The first limiting part 22 and the second limiting part 23 are distributed at intervals along the axial direction of the guide rod 2. The first limiting part 22 can be a first metal gasket, and the second limiting part 23 can be a second metal gasket. The vibration absorbing member 21 is located between the first limiting part 22 and the second limiting part 23. The first limiting part 22 and the second limiting part 23 can axially limit the vibration absorbing member 21 to prevent the vibration absorbing member 21 from moving axially and affecting the force-bearing effect of the guide rod 2, that is, to improve the stability of the movement of the guide rod 2.
[0045] In some embodiments, the inner circumference of the guide tube 1 is provided with a limiting rib 26. When the guide rod 2 is extended to the maximum position, the second limiting part 23 and the limiting rib 26 are axially pressed and limited.
[0046] Combination Figure 1 and Figure 3 As shown, the guide tube 1 has a radially recessed structure near its end, and a limiting rib 26 is formed on the inner circumferential wall of the guide tube 1 after the recess. Therefore, when the guide rod 2 is pulled to its maximum distance relative to the guide tube 1, if the first limiting part 22 is located... Figure 3 The second limiting part 23 is located on the left side of the vibration absorbing member 21. Figure 3 When the guide rod 2 is on the right side of the vibration absorber 21, the second limiting part 23 can make abutting contact with the limiting rib 26, thereby preventing the guide rod 2 from being pulled out; and if the first limiting part 22 and the second limiting part 23 are made of metal, the limiting effect will be better, and the risk of the guide rod 2 being pulled out can be further reduced.
[0047] In some embodiments, the inner circumferential wall of the end of the guide pipe 1 is further provided with a guide support structure 24, and the guide rod 2 is adapted to penetrate the guide support structure 24 and is telescopic relative to the guide pipe 1.
[0048] The guide support structure 24 is arranged at the end of the guide pipe 1 for extending into one end of the guide rod 2, and is fixedly connected with the guide pipe 1. The guide support structure 24 is provided with a penetrating hole, and the guide support structure 24 is fixedly connected to the inner circumferential wall of the guide pipe 1. The guide rod 2 can penetrate the penetrating hole, and the limiting rib 26 is close to the guide support structure 24, as shown in Figure 1 The limiting rib 26 is located on the left side of the guide support structure 24. When the guide rod 2 is pulled out to the maximum position, the second limiting part 23 is limited by the limiting rib 26, and the guide support structure 24 supports the guide rod 2, so that the guide rod 2 and the guide pipe 1 have two force positions, thereby ensuring the stability of the movement of the guide rod 2.
[0049] In some embodiments, referring to Figure 4 The guide support structure 24 includes a guide sleeve 243, a sealing ring 241 and a connecting block 242. The guide sleeve 243 is detachably connected to the guide pipe 1. The connecting block 242 and the guide sleeve 243 are provided with the sealing ring 241 along the axial direction of the guide pipe 1. The guide rod 2 penetrates the guide sleeve 243, the sealing ring 241 and the connecting block 242 and is in interference fit with the sealing ring 241.
[0050] In practice, the guide sleeve 243 can be threadedly connected with the guide pipe 1. The guide sleeve 243 includes a first section 2431 and a second section 2432. The connecting block 242 is provided with a groove 2421. The first section 2431 of the guide sleeve 243 is provided with a first external thread 2433. The second section 2432 of the guide sleeve 243 is provided with a second external thread 2434. The second section 2432 extends into the groove 2421 of the connecting block 242, thereby realizing the connection between the guide sleeve 243 and the connecting block 242. The first section 2431 is threadedly connected with the inner circumferential wall of the guide pipe 1 through the first external thread 2433 on the outer periphery, thereby realizing the connection between the guide sleeve 243 and the guide pipe 1. The sealing ring 241 is arranged between the guide sleeve 243 and the connecting block 242 and is extruded during the connection of the guide sleeve 243 and the connecting block 242. The sealing ring 241 is in cooperation with the guide rod 2. During the movement of the guide rod 2 relative to the guide pipe 1, the connecting block 242 and the guide sleeve 243 can be used as the structure for supporting the guide rod 2, thereby realizing the stable movement of the guide rod 2.
[0051] Of course, the guide sleeve 243, connecting block 242, and sealing ring 241 can also be fixedly connected to the guide tube 1 by riveting or plastic coating, which can support the guide rod 2, and the sealing ring 241 can reduce the vibration noise during the extension and retraction of the guide rod 2. That is, the vibration absorber 21 vibrates inside the guide tube 1. Since the vibration absorber 21 has a flocked layer, it reduces the impact noise. The guide rod 2 and the sealing ring 241 are interference-fitted, and the two work together to reduce the vibration noise problem to a certain extent.
[0052] This utility model embodiment also discloses a tailgate support structure 1000, including a support rod assembly and the aforementioned guide rod assembly 100. The support rod assembly includes an outer support tube 3 and an inner support tube 4. At least a portion of the inner support tube 4 is movably connected to the outer support tube 3 and is telescopic relative to the outer support tube 3. One end of the guide tube 1 is fixed inside the outer support tube 3, and one end of the guide rod 2 is fixed inside the inner support tube 4. When the inner support tube 4 telescopically extends relative to the outer support tube 3, it drives the guide rod 2 to telescopically extend relative to the guide tube 1.
[0053] In other words, the inner diameter of the outer support tube 3 is larger than the outer diameter of the guide tube 1, and the outer diameter of the inner support tube 4 is smaller than the inner diameter of the outer support tube 3. One end of the guide tube 1 is connected to one end of the outer support tube 3, and the other end of the guide tube 1 is used to allow the guide rod 2 to extend into it. The guide rod 2 can extend and retract within the guide tube 1, and the end of the guide rod 2 away from the guide tube 1 is connected to the end of the inner support tube 4 away from the outer support tube 3. So when the inner support tube 4 extends and retracts relative to the outer support tube 3, the corresponding guide rod 2 can extend and retract relative to the guide tube 1. The internal guide tube 1 and guide rod 2 can support the inner support tube 4 and the outer support tube 3, thereby ensuring the structural strength and operational stability of the tailgate support structure 1000.
[0054] In some embodiments, one end of the outer support tube 3 is detachably connected to one end of the guide tube 1, and the end of the inner support tube 4 away from the outer support tube 3 is detachably connected to the guide rod 2.
[0055] Reference Figure 5 and Figure 6As shown, one end of the outer support tube 3 is provided with a first mounting socket 31, and the end of the inner support tube 4 away from the outer support tube 3 is provided with a second mounting socket 41. One end of the guide tube 1 is connected to a threaded mounting block 11, and the other end of the guide tube 1 is provided with a threaded mounting part 25. That is, after the guide rod assembly 100 in its natural state is threadedly connected to the threaded mounting block 11, the outer support tube 3 and the inner support tube 4 are sequentially passed through the guide rod assembly 100 in its natural state. The threaded mounting part 25 at the other end of the guide rod assembly 100 in its natural state is threadedly connected to the second mounting socket 41, and the threaded mounting block 11 is threadedly connected to the first mounting socket 31. This achieves a detachable connection between the outer support tube 3 and the guide tube 1, and a detachable connection between the end of the inner support tube 4 away from the outer support tube 3 and the guide rod 2, so that the guide rod assembly 100 can be replaced when it is damaged.
[0056] In some embodiments, the tailgate support structure 1000 further includes an elastic element 5, which is sleeved on the guide rod assembly 100. One end of the elastic element 5 is connected to the outer support tube 3 and the other end is connected to the inner support tube 4.
[0057] In practice, the elastic element 5 is a strut spring. The strut spring cooperates with the guide rod assembly 100, the outer support tube 3, and the inner support tube 4 to ensure that no severe torsional deformation occurs during the return process of the strut spring. At the same time, it ensures that the elastic force of the strut spring is always along the axial direction of the guide rod assembly 100. That is, the strut spring can exert a force on the guide rod assembly 100 to move. For example, when the strut spring is compressed, it can generate an outward force to push the guide rod 2 to move outward. The strut spring can realize the smooth movement of the guide rod assembly 100.
[0058] This utility model embodiment also discloses a vehicle, including a tailgate, a drive unit and the aforementioned tailgate support structure 1000. One end of the tailgate support structure 1000 is connected to the tailgate and the other end is connected to the vehicle body. The drive unit drives the tailgate to open or close. When the tailgate opens or closes, it drives the inner support tube 4 to move relative to the outer support tube 3, and the guide rod 2 to move relative to the guide tube 1.
[0059] In practice, the tailgate can be opened or closed by a drive component, which is a motor. During the opening or closing process, the inner support tube 4 of the tailgate support structure 1000 is extended relative to the outer support tube 3, and at this time the guide rod 2 is also extended relative to the guide tube 1.
[0060] Specifically, when the tailgate is in the closed position, the inner support tube 4 of the tailgate support structure 1000 is in a contracted state relative to the outer support tube 3. At this time, the guide rod assembly 100 is also in a contracted state, and the elastic element 5 is compressed to generate an outward axial thrust to overcome the door's gravitational torque. The guide rod assembly 100 supports the outer support tube 3 and the inner support tube 4, and also restricts the deformation of the elastic element 5. At this time, the vibration absorber 21 is in contact with the guide tube 1, and the guide rod 2 is in contact with the guide sleeve 243 and is subjected to force, keeping the guide rod assembly 100 as a whole straight.
[0061] Furthermore, during the process of the tailgate moving from the closed position to the highest open position, the direction of the tailgate's gravitational moment does not change, and the tailgate support structure 1000... Figure 5 The contraction state shown gradually moves to, as Figure 6 The device is in an elongated state as shown, but during this process, the elastic element 5 is always under pressure, generating an outward axial thrust to overcome the door's gravitational torque. The guide rod assembly 100 is... Figure 1 The contraction becomes Figure 2 During the elongated state, the vibration absorbing component 21 slides and rubs against the guide tube 1 during the change process. At the same time, the vibration absorbing component 21 can rotate freely and change its contact position with the guide tube 1 during the friction process. The elastic component 5 cooperates with the guide rod assembly 100, the outer support tube 3 and the inner support tube 4 to ensure that no serious torsional deformation occurs during the reset process of the elastic component 5, and to ensure that the elastic force of the elastic component 5 is always along the axial direction of the guide rod assembly 100.
[0062] At the same time, when the tailgate is open and in its highest position, the tailgate support structure 1000 is in a state of... Figure 6 In its elongated state, the second limiting part 23 contacts the limiting rib 26 of the guide tube 1, restricting the movement range of the guide rod 2. The length of the guide rod assembly 100 can be adjusted according to the overall length of the outer support tube 3 and the inner support tube 4. Compared with the gas springs of the prior art, which suffer from problems such as force attenuation or failure during use, the present invention has a simple structure and ensures that the guide rod assembly 100 has no force change and moves smoothly during the opening or closing of the tailgate.
