[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 As shown in Embodiment 1, a telescopic support device includes: a bracket 1, a slide rod 2, a first connecting rod 3, a second connecting rod 4, a drive cylinder 5, and a support plate 6. The bracket 1 is fixedly installed at the bottom of the vehicle body. A second connecting plate 2-1 is fixedly installed on the left side of the bottom end of the slide rod 2. A sleeve 1-2 is fixedly installed on the right end of the bracket 1. The slide rod 2 is slidably installed on the right end of the bracket 1. The drive cylinder 5 is rotatably installed on the bottom surface of the left end of the bracket 1. A first connecting plate 1-1 is provided on the left side of the sleeve 1-2. The first connecting plate 1-1 is fixedly installed on the bottom surface of the bracket 1. The first connecting rod 3 and the second connecting rod 4 are both rotatably installed on the output end of the drive cylinder 5. The end of the first connecting rod 3 away from the drive cylinder 5 is rotatably installed on the bottom surface of the right end of the bracket 1. The end of the second connecting rod 4 away from the drive cylinder 5 is rotatably installed on the bottom end of the slide rod 2. The support plate 6 is rotatably installed on the bottom end of the slide rod 2.

[0021] The end of the second connecting rod 4 away from the drive cylinder 5 is rotatably mounted on the top of the second connecting plate 2-1, the support plate 6 is rotatably mounted on the bottom of the second connecting plate 2-1, the slide rod 2 is slidably mounted inside the sleeve 1-2, and the end of the first connecting rod 3 away from the drive cylinder 5 is rotatably mounted on the first connecting plate 1-1.

[0022] In use, bracket 1 is fixedly installed on the bottom surface of the vehicle body. When the drive cylinder 5 is started, the connection between the first connecting rod 3 and the second connecting rod 4 moves towards the sleeve 1-2. When the connection between the first connecting rod 3 and the second connecting rod 4 moves, since one end of the first connecting rod 3 is connected to the first connecting plate 1-1 and one end of the second connecting rod 4 is connected to the second connecting plate 2-1, the first connecting rod 3 rotates relative to the bracket 1. At this time, it can drive one end of the second connecting rod 4 to rotate, so that the second connecting rod 4 rotates relative to the sliding rod 2, causing the bottom end of the sliding rod 2 to descend, allowing the sliding rod 2 to slide downward within the sleeve 1-2.

[0023] In the initial state, the car is first lifted up, and the support device is fixed to the bottom of the car body. The support device is in a suspended state, the position of bracket 1 remains unchanged, and the drive cylinder 5 drives the connection between the first link 3 and the second link 4, thereby causing the slide bar 2 to slide relative to the sleeve 1-2 until the support plate 6 contacts the ground. Continue to drive the drive cylinder 5 so that the bracket 1 lifts the car body. After the car body is separated from the front of the car, it can touch the ground to lift the load and provide reliable support.

[0024] like Figures 2 to 3 As shown in Embodiment 2, both the second connecting plate 2-1 and the first connecting plate 1-1 are provided with sliding grooves 7-1. The sliding grooves 7-1 are connected to rotating grooves 7 on both sides of the end near the driving cylinder 5, and the sliding grooves 7-1 are connected to receiving grooves 7-2 on both sides of the end away from the driving cylinder 5. The first connecting rod 3 and the second connecting rod 4 are both fixedly installed with rotating shafts 8 at the ends away from the driving cylinder 5. An elliptical limiting block 8-1 is fixedly installed at the end of the rotating shaft 8. The rotating shaft 8 is rotatably disposed in the sliding groove 7-1, and the limiting block 8-1 can rotate inside the rotating groove 7 and can be inserted into the receiving groove 7-2.

[0025] When the limiting block 8-1 is inside the rotating groove 7, the limiting block 8-1 is restricted by the rotating groove 7, so that the limiting block 8-1 cannot move towards the sleeve 1-2. At this time, the limiting block 8-1 and the rotating shaft 8 rotate on the end of the slide groove 7-1 near the drive cylinder 5. The first connecting rod 3 can rotate on the first connecting plate 1-1, and the second connecting rod 4 can rotate on the second connecting plate 2-1. When the first connecting rod 3 and the second connecting rod 4 are rotated to a vertical state, the limiting block 8-1 is in a horizontal state. At this time, the limiting block 8-1 is not restricted by the rotating groove 7, and the drive cylinder continues to move, so that the rotating shaft 8 can slide in the slide groove 7-1, allowing the first connecting rod 3 and the second connecting rod 4 to move in a vertical state. The receiving groove 7-2 can receive the limiting block, so that the rotating shaft 8 can slide to the end of the slide groove 7-1.

[0026] When the first link 3 and the second link 4 are in a vertical position, the rotating shaft 8 is in a horizontal position. At this time, the rotating shaft 8 can be inserted into the slide groove 7-1, so that the first link 3 and the second link 4 can move while maintaining a vertical position.

[0027] Semi-circular insert rods 9 are fixedly installed on both the first link 3 and the second link 4. When the first link 3 and the second link 4 are in a vertical state, the two insert rods 9 can be assembled into a round rod. The end of the insert rod 9 is provided with a positioning hole 9-1.

[0028] When the first link 3 and the second link 4 are in a vertical position, the two insert rods 9 can be assembled into a complete round rod, so that the two positioning holes 9-1 can overlap each other.

[0029] The slide bar 2 has an insertion hole 2-2, and the insertion rod 9 can be inserted into the insertion hole 2-2. The length of the insertion rod 9 is greater than the depth of the insertion hole 2-2. The positioning bolt 11 can be inserted into the positioning hole 9-1.

[0030] When the first link 3 and the second link 4 move in a vertical position, they can drive the round rod to move, so that the round rod is inserted into the insertion hole 2-2 and the insertion rod 9 passes through the other end of the insertion hole 2-2, so that the positioning hole 9-1 is not blocked by the sliding rod 2. At this time, the first link 3 and the second link 4 can remain locked. When the positioning bolt 11 is inserted into the positioning hole 9-1, the installation of the insertion rod 9 and the sliding rod 2 is more stable.

[0031] In this second embodiment, the locking effect of keeping the first link 3 and the second link 4 in a vertical state ensures that even when the drive cylinder 5 does not apply force to the rotation of the first link 3 and the second link 4, the slide bar 2 still provides stable support for the vehicle body.

[0032] like Figures 4 to 5As shown, in Embodiment 3, a semi-circular threaded sleeve 10 is fixedly installed on both the first connecting rod 3 and the second connecting rod 4. When the first connecting rod 3 and the second connecting rod 4 are in a vertical state, the two threaded sleeves 10 can be assembled into a complete threaded sleeve.

[0033] When the first link 3 and the second link 4 are in a vertical position, the two threaded sleeves 10 can be assembled into a complete threaded sleeve.

[0034] The slide rod 2 has a groove 2-3 on the right side and an insertion hole 2-2 on the left side. The insertion hole 2-2 communicates with the groove 2-3. The threaded sleeve 10 can be inserted into the insertion hole 2-2. The length of the threaded sleeve 10 is smaller than the depth of the insertion hole 2-2. A positioning bolt 11 is slidably installed on the inner wall of the groove 2-3. The positioning bolt 11 can be threadedly connected to the threaded sleeve 10.

[0035] When the first link 3 and the second link 4 move in a vertical position, they can drive the threaded sleeve to move, so that the threaded sleeve is inserted into the insertion hole 2-2 and the positioning bolt 11 slides in the groove 2-3, so that the end of the positioning bolt 11 protrudes relative to the slide rod 2. When the positioning bolt 11 is rotated, it drives the positioning bolt 11 to be threadedly connected to the threaded sleeve 10. At this time, the first link 3 and the second link 4 can remain locked, so that the threaded sleeve 10 and the slide rod 2 are installed more stably.

[0036] Compared to Embodiment 2, Embodiment 3 has the effect of storing the positioning bolt 11 on the slide bar 2, which makes it convenient to avoid searching for the positioning bolt 11 during actual use, and also avoids the situation where manual locking cannot be used due to the loss of the positioning bolt 11.

[0037] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
