[0037] like Figures 1 to 4 As shown, this embodiment provides a vehicle leg extension device, which includes a connecting shaft 2 and an extension block 3. The connecting shaft 2 can be connected to the lower end of the vehicle leg 1, and the connecting shaft 2 can be detachably connected to the lower end of the vehicle leg 1, so as to facilitate the disassembly and assembly of the vehicle leg extension device according to needs; one side of the extension block 3 is rotatably connected to the connecting shaft 2, and the extension block 3 has a working position and a stowed position compared to the vehicle leg 1. The extension block 3 can be flipped around the axial direction of the connecting shaft 2 to switch between the working position and the stowed position. When the extension block 3 is in the working position, the extension block 3 is located directly below the vehicle leg 1, and when the extension block 3 is in the stowed position, the extension block 3 is against the side of the vehicle leg 1. Among them, the vehicle leg 1 is retractable, and when it needs to support the ground, the vehicle leg 1 is extended, and when the vehicle is driving, the vehicle leg 1 is retracted; the lower end of the vehicle leg 1 refers to the end close to the ground. The extension block 3 is rotatably connected to the connecting shaft 2, so that the extension block 3 can be flipped between the stowed position and the working position to meet the requirements of different working states; the extension block 3 is flipped to the working position, so that the extension block 3 is located directly below the vehicle outrigger 1. When the vehicle outrigger 1 is supporting the ground, the extension block 3 touches the ground to support the vehicle outrigger 1 to meet the required ground supporting length, thereby ensuring the stability of the vehicle; the extension block 3 is flipped to the stowed position, so that the extension block 3 abuts against the side of the vehicle outrigger 1, so that when the vehicle is driving, the extension block 3 is prevented from interfering with the external environment and affecting the driving safety of the vehicle and the vehicle outrigger 1. The use of the vehicle outrigger extension device can quickly extend the travel of the vehicle outrigger 1 of the manufactured vehicle without the need to modify or replace the vehicle outrigger 1, which not only saves costs, but also saves time, has a wide range of applications, and has better safety and flexibility in use.
[0038] In this embodiment, the lower end of the vehicle leg 1 is a support base plate 11, and the opposite ends of the support base plate 11 are tilted upward, and the connecting shaft 2 is connected to the lower end surface of the support base plate 11 and is located on the tilted surface. Specifically, the vehicle leg extension device also includes at least two connecting seats arranged at intervals at the lower end of the vehicle leg 1, and the specific connecting seats are arranged on the tilted surface, and the connecting shaft 2 is rotatably or fixedly connected to the two connecting seats. That is, the connecting shaft 2 is connected to the vehicle leg 1 through the connecting seat, and the connecting seat not only provides support for the connecting shaft 2, but also allows a certain gap between the connecting shaft 2 and the lower end surface of the vehicle leg 1, so that the extension block 3 can be smoothly rotated to the retracted position.
[0039] Optionally, the connecting seat is detachably connected to the vehicle outrigger 1, so that the vehicle outrigger extension device can be disassembled and assembled according to needs, which is convenient for replacing extension blocks 3 of different heights or replacing defective vehicle outrigger extension devices. Exemplarily, the connecting seat is detachably connected to the lower end of the vehicle outrigger 1 by bolts.
[0040] like Figure 1As shown, in this embodiment, the vehicle outrigger extension device also includes a first stopper 4, which is detachably connected to the vehicle outrigger 1 and the extension block 3, and the first stopper 4 can fix the extension block 3 in the working position. The extension block 3 is fixed in the working position by the first stopper 4, so that the vehicle outrigger 1 can smoothly press the extension block 3 when it is extended to support the ground, thereby ensuring the reliability of the ground support process; when the extension block 3 needs to be flipped, the first stopper 4 is removed, so that the extension block 3 can be smoothly flipped to achieve the folding of the extension block 3. Exemplarily, a first connecting piece is provided on one side of the extension block 3, and a second connecting piece is provided on the vehicle outrigger 1. The first stopper 4 includes a bolt and a nut, which is detachably connected to the first connecting piece and the second connecting piece through the bolt and the nut, thereby achieving the position fixation or release of the extension block 3. Of course, in other embodiments, the first limiting member 4 may also be other structures, for example, the first limiting member 4 includes a locking rod and a lock core, one of the locking rod and the lock core is arranged on the extension block 3, and the other is arranged on the vehicle support leg 1, and the locking rod and the lock core can be locked or separated; or the first limiting member 4 is a magnet, the vehicle support leg 1 is made of metal material or a metal block is arranged on it, and the magnet can be attracted to the vehicle support leg 1 or the metal block.
[0041] like Figure 2 As shown, further, the vehicle leg extension device also includes a second stopper 5, which is detachably connected to the side of the vehicle leg 1 and the extension block 3, and the second stopper 5 can fix the extension block 3 in the stowed position. When the extension block 3 is flipped to the stowed position, the extension block 3 is fixed in the stowed position by the second stopper 5, so as to prevent the extension block 3 from flipping to the working position under the action of gravity, and at the same time ensure the position stability of the extension block 3, thereby ensuring the reliability of the use of the vehicle leg extension device. When the extension block 3 needs to be flipped to the working position, the extension block 3 can be smoothly flipped after the second stopper 5 is removed. Exemplarily, the second stopper 5 includes a bolt, a third connecting piece is provided on the extension block 3, and a fourth connecting piece is provided on the vehicle leg 1, and the bolt passes through the third connecting piece and is threadedly connected with the fourth connecting piece to achieve the position fixation of the extension block 3. The structure is simple, the operation is convenient, and the cost is low. Of course, in other embodiments, the second limit member 5 may also be other structures. For example, the second limit member 5 is a magnet or the second limit member 5 includes a lock rod and a lock core, etc. The specific structure refers to the first limit member 4 and will not be repeated here.
[0042] Optionally, the extension block 3 can be turned over between the working position and the stowed position by manual turning or by driving the extension block 3 to turn over by an electric drive. When turned over manually, the extension block 3 can be fixed by the first stopper 4 and the second stopper 5 in the working position and the stowed position respectively. When driven by the electric drive, the electric drive drives the connection extension block 3 to drive the extension block 3 to rotate around the connecting shaft 2. For example, the electric drive includes a driving cylinder and a connecting rod, the driving cylinder is hinged to the vehicle support leg 1, and the output end of the driving cylinder is connected to one end of the connecting rod, and the other end of the connecting rod is hinged to one side of the extension block 3, and when the output end of the driving cylinder is extended, the extension block 3 is driven to rotate. Of course, in other embodiments, the electric drive can also be other, for example, the electric drive is a motor, the extension block 3 is rotatably connected to the connecting shaft 2 through a rotating shaft, the connecting shaft 2 is fixedly connected to the vehicle support leg 1, and the motor drives the connection rotating shaft to drive the rotating shaft to rotate, thereby driving the extension block 3 to rotate. The extension block 3 is driven to rotate by an electric drive component, and the first limit member 4 and the second limit member 5 mentioned above can be used to fix the position of the extension block 3, or the first limit member 4 and the second limit member 5 can be omitted, depending on actual needs.
[0043] In another embodiment, Figure 3 and Figure 4 As shown, the vehicle leg extension device includes a stretching elastic member 6, and the two ends of the stretching elastic member 6 are respectively connected to the vehicle leg 1 and the extension block 3, so that the extension block 3 can be limited to the working position, and the extension block 3 can be flipped to the stowed position under the force, and stabilized in the stowed position under the action of the stretching elastic member 6. The stretching elastic member 6 provides a pulling force, so that when the extension block 3 is in the working position, the stretching elastic member 6 pulls the extension block 3 close to the lower end surface of the vehicle leg 1. Preferably, the connection position of the stretching elastic member 6 and the extension block 3 is as far away from the connecting shaft 2 as possible, so that the effective pulling force of the stretching elastic member 6 on the extension block 3 is large, that is, the angle between the extension block 3 and the lower end surface of the vehicle leg 1 is as small as possible, thereby ensuring the reliability of the vehicle leg 1 when it is extended to support the ground. At the same time, force is applied to the extension block 3 so that the extension block 3 is subjected to force to overcome the elastic force of the stretching elastic member 6 and flip to the retracted position until the extension block 3 flips to the retracted position, that is, after the extension block 3 abuts against the side of the vehicle outrigger 1, the stretching elastic member 6 still provides a pulling force to tighten the extension block 3 toward the side of the vehicle outrigger 1. Even after the force is removed, the extension block 3 can be stabilized in the retracted position.
[0044] Optionally, the stretching elastic member 6 is a stretching spring, elastic rubber or a hydraulic cylinder, etc., which is specifically configured according to actual needs.
[0045] In this embodiment, the vehicle leg extension device further includes a first connecting rod 7 and a second connecting rod 8, the first connecting rod 7 is used to be connected to one side of the vehicle leg 1 and is parallel to the connecting shaft 2, the second connecting rod 8 is connected to one side of the extension block 3 and is parallel to the connecting shaft 2, and the two ends of the stretching elastic member 6 are respectively connected to the first connecting rod 7 and the second connecting rod 8. The first connecting rod 7 and the second connecting rod 8 provide support for the stretching elastic member 6, and are arranged parallel to the rotation axis, so that the stretching elastic member 6 provides a pulling force for the extension member in the working position and the stowed position, and does not affect the flipping of the extension member.
[0046] Optionally, a plurality of stretch elastic members 6 are provided, and a plurality of corresponding first connecting rods 7 and second connecting rods 8 are also provided. The plurality of stretch elastic members 6 are provided on the same side or on two opposite sides. For example, two stretch elastic members 6 are provided, and the two stretch elastic members 6 are respectively provided on two opposite sides of the extension block 3 to provide relatively uniform and sufficient tension.
[0047] Further preferably, on one side of the extension block 3 connected to the second connecting rod 8, the second connecting rod 8 is located at a corner opposite to the connecting shaft 2. That is, the connection between the stretching elastic member 6 and the extension block 3 is located at a corner of the extension block 3, so that when the extension block 3 is in the stowed position, the stretching elastic member 6 provides sufficient effective pulling force to stabilize the extension block 3 in the stowed position, thereby preventing the extension block 3 from falling to the working position due to gravity and shaking during the driving of the vehicle, thereby ensuring the reliability of the vehicle-mounted outrigger extension device and the driving safety of the vehicle.
[0048] In this embodiment, a weight-reducing cavity is provided inside the extension block 3, that is, the extension block 3 is hollow. Reducing the overall weight of the extension block 3 is conducive to reducing the force on the stretching elastic member 6 or the second limiting member 5 when the extension block 3 is in the retracted position, thereby ensuring the stability of the position of the extension block 3.
[0049] This embodiment also provides a vehicle-mounted support frame leg, which includes a vehicle-mounted support leg 1 and the above-mentioned vehicle-mounted support leg extension device. The vehicle-mounted support leg has a variable stroke, better flexibility and safety in use, and lower manufacturing cost.
[0050] This embodiment also provides a vehicle, which includes a vehicle body and the above-mentioned on-board support leg, has a low cost, a variable travel of the on-board support leg, and has good flexibility and safety in use.
[0051] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
