Description

Technical Field

[0001] This utility model relates to the field of amphibious vehicle technology, and in particular to a vehicle with a telescopic suspension device. Background Technology

[0002] The suspension system of existing amphibious vehicles increases the width of the vehicle when traveling on land, which reduces the vehicle's passability on land.

[0003] For example, announcement number "CN217994037U" discloses an "amphibious vehicle" including a vehicle body, a first buoyancy device, a second buoyancy device, and a third buoyancy device. The center of gravity of the vehicle body is located at the front end. The first buoyancy device is connected to the front of the vehicle body, and the second and third buoyancy devices are respectively connected to the two sides of the vehicle body. There are gaps between the second and third buoyancy devices and the vehicle body. The second and third buoyancy devices are symmetrically arranged along the central axis of the vehicle body's length. The first, second, and third buoyancy devices are all higher than the lowest point of the vehicle's wheels. However, in practical applications, this type of suspension device increases the vehicle's width when traveling on the road, affecting operation. Summary of the Invention

[0004] In view of the problem mentioned in the background art that the suspension device of amphibious vehicles affects road traffic, this utility model provides a vehicle with a telescopic suspension device, which allows the suspension device to be close to the vehicle body when the vehicle is traveling on land, without affecting the width of the vehicle, thus improving the vehicle's passability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A vehicle with a telescopic suspension device includes a vehicle body, a fixed plate connected to the vehicle body, a base provided on the fixed plate, a telescopic connecting rod movably connected to the base, and an airbag connected to the end of the telescopic connecting rod away from the base. The telescopic connecting rod has a retracted state and an extended state. When in the retracted state, the airbag is close to the vehicle body, and when in the extended state, the airbag is away from the vehicle body. In existing amphibious vehicles, the need to operate on water necessitates maintaining buoyancy. This requires the addition of suspension systems to ensure buoyancy. In practical use, airbags are typically the chosen suspension system. While airbags are easy to inflate and deflate, their efficiency is relatively low. In off-road applications, frequent switching between water and surface modes is necessary. Inflating and deflating the airbags each time would result in significant time loss and reduce their lifespan. Furthermore, keeping the airbags constantly inflated would increase the vehicle's overall width. While this increase is not a concern on water, it becomes a significant burden on roads, especially off-road terrain, where the wider vehicle reduces the driver's driving experience.

[0007] Therefore, to address the aforementioned issues, this application adds a telescopic connecting rod to the airbag. This telescopic connecting rod can be a multi-link hinged device, such as a three-link hinge or a four-link parallelogram hinge. This allows the size of the telescopic connecting rod to be increased or decreased when each link rotates, thereby achieving the telescopic and deployment effects. Therefore, the telescopic connecting rod in this application has two states: a retracted state and an deployed state. When the telescopic connecting rod is in the retracted state, the gap between the airbag and the vehicle body decreases, causing the airbag to move closer to the vehicle body, thus reducing the overall width of the vehicle and ensuring its passability on the road. When the vehicle needs to wade through water, the telescopic connecting rod is controlled to be in the deployed state, thereby ensuring the vehicle's levitation effect.

[0008] The connection between the mounting plate and the vehicle body can be a fixed connection or a detachable connection. Fixed connections include, but are not limited to, welding and integral molding (i.e., the mounting plate itself is part of the vehicle), while detachable connections include, but are not limited to, bolt connections and snap-fit ​​connections, thereby improving the flexibility of installation and disassembly.

[0009] Preferably, the vehicle body is connected to a tire, and the fixing plate is connected to the vehicle body above the tire. Positioning the fixing plate above the tire allows the telescopic connecting rod to move above the tire, reducing interference with the tire and improving operability.

[0010] Preferably, the telescopic connecting rod includes a support rod and a folding rod, both of which are rotatably connected to a base. The end of the support rod away from the base is connected to an airbag. A groove is provided on the support rod, and the end of the folding rod away from the base is slidably connected within the groove. The telescopic connecting rod includes a support rod and a folding rod, wherein the support rod connects the base and the airbag, and the folding rod, by connecting to the groove of the support rod, can slide relative to the support rod, thus achieving the telescopic effect.

[0011] Preferably, the folding rod is located above the support rod. When the folding rod rotates, it causes the support rod and airbag to rotate upwards and closer to the vehicle body. When retracted, the folding rod causes the support rod and airbag to move upwards, thereby avoiding interference with the tires while ensuring effective support for the airbag.

[0012] Preferably, the base includes a side plate and a bottom plate. The bottom plate is connected to a fixed plate, and a mounting groove is formed between the side plate and the bottom plate. The support rod is rotatably connected within the mounting groove, and the folding rod is connected to the side of the side plate away from the mounting groove. The folding rod is located on both sides of the support rod, and a sliding rod with a through-groove is provided between the folding rods. The base consists of a side plate and a bottom plate, with the side plates located on both sides of the bottom plate. The side plates and the bottom plate form a "U"-shaped groove structure. The bottom plate is connected to the fixed plate to ensure the stability of the connection. The support rod is rotatably connected within the mounting groove, while the folding rod is connected outside the mounting groove. That is, the folding rod and the support rod are located on both sides of the side plate, thus ensuring that the folding rod and the support rod do not interfere with each other. Furthermore, a groove is provided within the support rod. By providing a sliding rod with a sliding connection groove on the folding rod, one end of the folding rod can slide relative to the support rod, thereby achieving the telescopic effect of the entire telescopic connecting rod while ensuring the movement stability of the folding rod.

[0013] Preferably, the fixing plate is provided with several bases, and each base is connected to a telescopic connecting rod. The multiple bases on the fixing plate, connected by multiple telescopic connecting rods, make the airbag's fixation more stable, thereby effectively supporting the airbag and improving the uniformity of its suspension effect.

[0014] Preferably, the airbag is provided with several bandages, which are circumferentially attached to the airbag and connected to the telescopic connecting rod. By providing bandages to the airbag and connecting it via these bandages, the telescopic connecting rod is not directly connected to the airbag. The bandages' circumferential attachment to the airbag effectively secures and restrains it, preventing localized stress concentration and protecting the airbag's lifespan while improving stability.

[0015] Preferably, the bandage is connected end-to-end to form a joint and a loop, the loop connecting to the airbag and the joint connecting to the telescopic connecting rod. The bandage connection constrains the airbag around its circumference, forming the joint and loop. The loop ensures the stability of the constraint on the airbag, while the joint connecting to the telescopic connecting rod ensures the stability of the connection.

[0016] Preferably, a limiting and fixing unit is provided between the fixing plate and the airbag. This limiting and fixing unit includes, but is not limited to, hook locks, buckles, and elastic locking pins. The limiting and fixing unit secures the airbag when the telescopic connecting rod is in the retracted state, directly connecting and fixing the airbag to the vehicle body. This ensures that when the telescopic connecting rod is retracted, the airbag does not transfer all the pressure to the telescopic connecting rod; instead, a portion of the pressure is transferred to the vehicle body through the limiting and fixing unit, thus ensuring the service life of the telescopic connecting rod.

[0017] Preferably, the mounting plate is detachably connected to the vehicle body. This detachable connection makes connecting and disconnecting the mounting plate from the vehicle body easier and faster, allowing for the replacement of different mounting plates according to actual usage needs. This accommodates airbags of different sizes and driving requirements, improving the overall vehicle assembly flexibility.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) It enables the suspension device to be close to the vehicle body when the vehicle is driving on land, without affecting the width of the vehicle, thus improving the vehicle's passability.

[0020] (2) It can ensure the smoothness of the telescopic connecting rod's movement, improve the smoothness of operation, and ensure the stability of the airbag. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1:

[0035] like Figure 1 , 2 As shown in Figure 3, a vehicle with a telescopic suspension device includes a vehicle body 1, a fixed plate 11 connected to the vehicle body 1, a base 2 provided on the fixed plate 11, a telescopic connecting rod 3 movably connected to the base 2, and an airbag 4 connected to the end of the telescopic connecting rod 3 away from the base 2. The telescopic connecting rod 3 includes a retracted state and an extended state. When it is in the retracted state, the airbag 4 is close to the vehicle body 1, and when it is in the extended state, the airbag 4 is away from the vehicle body 1. In existing amphibious vehicles, the need to operate on water necessitates maintaining buoyancy. This necessitates the installation of suspension devices to ensure buoyancy. In practical applications, airbags are typically used. While airbags are easy to inflate and deflate, their efficiency is low. In off-road applications, frequent switching between water and surface modes is required. Inflating and deflating airbags each time would result in significant time loss and reduce their lifespan. Furthermore, keeping airbags inflated at all times increases the vehicle's overall width. While this increase is not a concern on water, it becomes a significant burden on roads, especially off-road terrain, where a wider vehicle body reduces the driver's driving experience.

[0036] Therefore, to address the aforementioned issues, this application adds a telescopic connecting rod 3 to the airbag 4. The telescopic connecting rod 3 can be a multi-link hinge device, such as a three-link hinge or a four-link parallelogram hinge, so that when each link rotates, the size of the telescopic connecting rod 3 can be increased or decreased, thereby achieving the telescopic and deployment effects. Therefore, the telescopic connecting rod 3 in this application includes two states: a retracted state and an deployed state. When the telescopic connecting rod 3 is in the retracted state, the gap between the airbag 4 and the vehicle body 1 is reduced, causing the airbag 4 to move closer to the vehicle body 1, thereby reducing the overall width of the vehicle and ensuring the vehicle's passability on the road. When the vehicle needs to wade through water, the telescopic connecting rod 3 is controlled to be in the deployed state, thereby ensuring the vehicle's levitation effect.

[0037] The connection between the fixing plate 11 and the vehicle body 1 can be a fixed connection or a detachable connection. The fixed connection includes, but is not limited to, welding and integral molding (i.e., the fixing plate 11 itself is part of the vehicle), while the detachable connection includes, but is not limited to, bolt connection and snap-fit ​​connection, thereby improving the flexibility of installation and disassembly.

[0038] like Figure 3 As shown, the vehicle body 1 is connected to a tire 12, and a fixing plate 11 is connected to the vehicle body 1 above the tire 12. By placing the fixing plate 11 above the tire 12, the telescopic connecting rod 3 moves above the tire 12, reducing interference with the tire 12 and improving operability.

[0039] like Figure 1 , 2 As shown in Figures 4 and 5, the telescopic connecting rod 3 includes a support rod 31 and a folding rod 32. Both the support rod 31 and the folding rod 32 are rotatably connected to the base 2. The end of the support rod 31 away from the base 2 is connected to the airbag 4. A groove 33 is provided on the support rod 31, and the end of the folding rod 32 away from the base 2 is slidably connected within the groove 33. The telescopic connecting rod 3 includes a support rod 31 and a folding rod 32. The support rod 31 is used to connect the base 2 and the airbag 4, while the folding rod 32, by connecting within the groove 33 of the support rod 31, can slide relative to the support rod 31, thus achieving the telescopic effect.

[0040] like Figure 2 , 3 As shown in Figure 4, the folding rod 32 is located above the support rod 31. When the folding rod 32 rotates, it drives the support rod 31 and the airbag 4 to rotate upwards and closer to the side of the vehicle body 1. When retracted, the folding rod 32 drives the support rod 31 and the airbag 4 to move upwards, thereby avoiding interference with the tire 12 while ensuring the support effect for the airbag 4.

[0041] like Figure 5As shown, the base 2 includes a side plate 21 and a bottom plate 22. The bottom plate 22 is connected to the fixed plate 11. An installation groove 23 is formed between the side plate 21 and the bottom plate 22. The support rod 31 is rotatably connected in the installation groove 23. The folding rod 32 is connected to the side of the side plate 21 away from the installation groove 23. The folding rod 32 is located on both sides of the support rod 31. A sliding rod 321 that passes through the sliding groove 33 is provided between the folding rods 32. The base 2 consists of a side plate 21 and a bottom plate 22. The side plate 21 is located on both sides of the bottom plate 22, forming a "U"-shaped groove structure. The bottom plate 22 is connected to the fixing plate 11 to ensure the stability of the connection. The support rod 31 is rotatably connected in the mounting groove 23, while the folding rod 32 is connected outside the mounting groove 23. That is, the folding rod 32 and the support rod 31 are located on both sides of the side plate 21, which ensures that the folding rod 32 and the support rod 31 will not interfere with each other. Furthermore, a sliding groove 33 is provided in the support rod 31. By providing a sliding rod 321 that slides through the sliding groove 33 on the folding rod 32, one end of the folding rod 32 can slide relative to the support rod 31, thereby realizing the telescopic effect of the entire telescopic connecting rod 3 and ensuring the movement stability of the folding rod 32.

[0042] like Figure 1 , 2 As shown, a plurality of bases 2 are provided on the fixing plate 11, and each base 2 is connected to a telescopic connecting rod 3. The multiple bases 2 on the fixing plate 11, and the connection between the multiple bases 2 and the multiple telescopic connecting rods 3, can make the fixing effect of the airbag 4 more stable, thereby effectively supporting the airbag 4 and improving the uniformity of the suspension effect of the airbag 4.

[0043] like Figure 1 As shown, several bandages 41 are provided on the airbag 4. The bandages 41 are circumferentially attached to the airbag 4 and connected to the telescopic connecting rod 3. By providing bandages 41 to the airbag 4 and connecting the airbag 4 through the bandages 41, the telescopic connecting rod 3 is not directly connected to the airbag 4. Through the circumferential attachment of the bandages to the airbag 4, the bandages can effectively fix and restrain the airbag 4, thereby avoiding local stress concentration in the airbag 4, protecting the service life of the airbag 4, and improving the stability of fixation.

[0044] like Figure 4 As shown, the bandage 41 is connected end to end to form a connector 42 and a collar 43. The collar 43 is connected to the airbag 4, and the connector 42 is connected to the telescopic connecting rod 3. The bandage 41 is connected end to end to constrain one circumference of the airbag 4 to form the connector 42 and the collar 43. The collar 43 ensures the stability of the constraint on the airbag 4, while the connector 42 is connected to the telescopic connecting rod 3 to ensure the stability of the connection.

[0045] like Figure 1As shown, the fixing plate 11 is detachably connected to the vehicle body 1. This detachable connection makes the connection and disassembly of the fixing plate 11 to the vehicle body 1 more convenient and quick. Different fixing plates 11 can be replaced according to actual usage needs, thus adapting to different sizes of airbags 4 and driving requirements, improving the overall vehicle assembly flexibility.

[0046] Example 2:

[0047] like Figure 6 As shown, in this embodiment, a limiting and fixing unit 5 is provided between the fixing plate 11 and the airbag 4. The limiting and fixing unit 5 in this embodiment is a hook connected to the airbag 4. The hook can connect to a pre-set hole on the vehicle body 1, thereby achieving the effect of fixing and constraining the airbag 4 by connecting the hook to the hole. In practical applications, the limiting and fixing unit 5 includes, but is not limited to, hook locks, buckles, and elastic locking pins. The limiting and fixing unit 5 can fix the airbag 4 when the telescopic connecting rod 3 is in the retracted state, directly connecting and fixing the airbag 4 to the vehicle body 1. This ensures that when the telescopic connecting rod 3 is in the retracted state, the airbag 4 will not transmit all the pressure to the telescopic connecting rod 3, but rather a portion of the pressure will be transmitted to the vehicle body 1 through the limiting and fixing unit 5, thus ensuring the service life of the telescopic connecting rod 3.

[0048] In addition to the structural features described above, this embodiment also includes a vehicle body 1, a fixed plate 11 connected to the vehicle body 1, a base 2 provided on the fixed plate 11, a telescopic connecting rod 3 movably connected to the base 2, and an airbag 4 connected to the end of the telescopic connecting rod 3 away from the base 2. The telescopic connecting rod 3 has a retracted state and an extended state. When in the retracted state, the airbag 4 is positioned close to the vehicle body 1; when in the extended state, the airbag 4 is positioned away from the vehicle body 1. A tire 12 is connected to the vehicle body 1, and the fixed plate 11 is connected to the vehicle body 1 above the tire 12. The telescopic connecting rod 3 includes a support rod 31 and a folding rod 32, both of which are rotatably connected to the base 2. The end of the support rod 31 away from the base 2 is connected to the airbag 4, and a groove 33 is provided on the support rod 31. The end of the folding rod 32 away from the base 2 is slidably connected within the groove 33. The folding rod 32 is located above the support rod 31. When the folding rod 32 rotates, it drives the support rod 31 and the airbag 4 to rotate upwards and closer to the vehicle body 1. The base 2 includes a side plate 21 and a bottom plate 22. The bottom plate 22 is connected to the fixed plate 11. A mounting groove 23 is formed between the side plate 21 and the bottom plate 22. The support rod 31 is rotatably connected in the mounting groove 23. The folding rod 32 is connected to the side of the side plate 21 away from the mounting groove 23. The folding rod 32 is located on both sides of the support rod 31. A sliding rod 321 that passes through the sliding groove 33 is provided between the folding rods 32. Several bases 2 are provided on the fixed plate 11. Each base 2 is connected to a telescopic connecting rod 3. Several bandages 41 are provided on the airbag 4. The bandages 41 are wrapped around the airbag 4 in a circumferential direction. The bandages 41 are connected to the telescopic connecting rods 3. The ends of the bandages 41 are connected to form a connector 42 and a collar 43. The collar 43 is connected to the airbag 4, and the connector 42 is connected to the telescopic connecting rod 3. The fixing plate 11 is detachably connected to the vehicle body 1.

[0049] A telescopic connecting rod 3 is added to the airbag 4. The telescopic connecting rod 3 can be a multi-link hinge device, such as a three-link hinge or a four-link parallelogram hinge. This allows the size of the telescopic connecting rod 3 to be increased or decreased when each link rotates, thereby achieving the telescopic and deployment effects. Therefore, the telescopic connecting rod 3 in this application has two states: a retracted state and an deployed state. When the telescopic connecting rod 3 is in the retracted state, the gap between the airbag 4 and the vehicle body 1 is reduced, causing the airbag 4 to move closer to the vehicle body 1, thereby reducing the overall width of the vehicle and ensuring the vehicle's passability on the road. When the vehicle needs to wade through water, the telescopic connecting rod 3 is controlled to be in the deployed state, thereby ensuring the vehicle's levitation effect.

[0050] The connection between the fixing plate 11 and the vehicle body 1 can be a fixed connection or a detachable connection. Fixed connections include, but are not limited to, welding and integral molding (i.e., the fixing plate 11 itself is part of the vehicle), while detachable connections include, but are not limited to, bolt connections and snap-fit ​​connections, thereby improving the flexibility of installation and disassembly. Positioning the fixing plate 11 above the tire 12 allows the telescopic connecting rod 3 to move above the tire 12, reducing interference with the tire 12 and improving operability. The telescopic connecting rod 3 includes a support rod 31 and a folding rod 32. The support rod 31 connects the base 2 and the airbag 4, while the folding rod 32 slides relative to the support rod 31 through a groove 33 connected to it, achieving the telescopic effect. During retraction, the folding rod 32 moves the support rod 31 and the airbag 4 upwards, thus avoiding interference with the tire 12 while ensuring effective support for the airbag 4. The base 2 consists of a side plate 21 and a bottom plate 22. The side plate 21 is located on both sides of the bottom plate 22, forming a "U"-shaped groove structure. The bottom plate 22 is connected to the fixing plate 11 to ensure the stability of the connection. The support rod 31 is rotatably connected in the mounting groove 23, while the folding rod 32 is connected outside the mounting groove 23. That is, the folding rod 32 and the support rod 31 are located on both sides of the side plate 21, which ensures that the folding rod 32 and the support rod 31 will not interfere with each other. Furthermore, a sliding groove 33 is provided in the support rod 31. By providing a sliding rod 321 that slides through the sliding groove 33 on the folding rod 32, one end of the folding rod 32 can slide relative to the support rod 31, thereby realizing the telescopic effect of the entire telescopic connecting rod 3 and ensuring the movement stability of the folding rod 32.

[0051] Multiple bases 2 are provided on the fixing plate 11. The connection between the multiple bases 2 and multiple telescopic connecting rods 3 makes the fixation of the airbag 4 more stable, thereby effectively supporting the airbag 4 and improving the uniformity of the airbag 4's suspension effect. Bandages 41 are provided on the airbag 4, connecting it to the airbag 4. This prevents the telescopic connecting rods 3 from being directly connected to the airbag 4. The bandages, by abutting against the airbag 4, effectively fix and constrain the airbag 4, thus avoiding localized stress concentration, protecting the lifespan of the airbag 4, and improving fixation stability. The ends of the bandages 41 are connected to constrain the airbag 4 around its circumference, forming a joint 42 and a collar 43. The collar 43 ensures the stability of the constraint on the airbag 4, while the joint 42 connects to the telescopic connecting rods 3, ensuring the stability of the connection. The mounting plate 11 and the vehicle body 1 are detachably connected, which makes the connection and disassembly between the mounting plate 11 and the vehicle body 1 more convenient and quick. Different mounting plates 11 can be replaced according to actual usage needs, thereby adapting to different sizes of airbags 4 and driving requirements, and improving the assembly flexibility of the whole vehicle.
