[0019] In order to further understand the present invention, preferred embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.
[0020] The description in this section is based on typical embodiments only, and the present invention is not limited to the scope of the embodiments described. Combinations of different embodiments, replacement of certain technical features in different embodiments, and replacement of certain technical features in the embodiments with the same or similar prior art methods are also within the scope of the present invention.
[0021] An auxiliary lifting leg for an all-terrain transport vehicle comprises two main components: a hydraulic element (1) and a leg element (2), which enables effective and controllable lifting of the vehicle.
[0022] Hydraulic element (1): The central component of the auxiliary jacking leg is the hydraulic element (1), which includes a hydraulic cylinder (103) and a piston rod (104). The upper protrusion (107) of the hydraulic cylinder is connected to the upper mounting sleeve (101) and the upper limit pin (102). The lower protrusion (108) of the piston is connected to the lower mounting sleeve (105) and the lower limit pin (106), and the lower mounting sleeve (105) and the lower limit pin (106) are also connected to the leg element (2). The movement of the piston rod (104) along the axial direction of the hydraulic cylinder (103) is adjusted to control the expansion and folding of the leg.
[0023] Leg element (2): The housing cover (203) of the leg element has an opening (206) for installing a sleeve (201) and a limit pin (202). The housing cover (203) is connected to the vehicle body via a leg plate (205), which is connected to a limit pin (204). This structure allows the legs to be freely unfolded and folded according to the position of the piston rod (104).
[0024] Therefore, the interrelationship and coordination between the hydraulic components and the outrigger elements ensure accurate and controllable operation of the auxiliary jacking legs, making it a reliable and efficient tool for supporting off-road vehicles in different working conditions.
[0025] The mounting sleeve with the limit pin is installed in the housing cover (203) of the support leg element. The housing cover (203) is equipped with symmetrical openings (206) at the upper and lower parts. The mounting sleeve (201) and the limit pin (202) are fixed through one opening, and the limit pin (204) is fixed through the second opening. Such a configuration provides a stable and symmetrical connection between the elements, creating a reliable foundation for the effective operation of the auxiliary lifting leg.
[0026] The housing cover (203) is used as a leg element in the leg element (2). The movement of the housing cover (203) is driven by the hydraulic element (1). The hydraulic element includes a hydraulic cylinder (103), whose piston pushes the piston rod (104) along the hydraulic cylinder axis. During its movement, the piston rod (104) interacts with the limit pin (106), triggering the movement of the housing cover (203) and the full deployment of the auxiliary lifting legs. When the legs are fully deployed, the leg disc (205) becomes the support point below them. This structure provides a clear action sequence and optimal operation of the auxiliary lifting legs.
[0027] When the auxiliary lifting legs are fully folded, the housing cover (203) can be fully integrated into the structure of the leg element (2) and the entire vehicle body. Therefore, in the folded state, the legs only occupy space inside the vehicle.
[0028] The auxiliary lifting legs can convert the axial extension of the hydraulic cylinder (103) into the extension of the legs and reduce the supporting pressure through the connecting rod mechanism. This results in the height of the entire vehicle body and the extension range of the legs being increased at the same time, thereby improving performance, expanding the application field, improving troubleshooting capabilities, and reducing lifting costs by increasing the lifting height.
[0029] The shell cover (203) is used as the leg element in the leg element (2). During the folding and unfolding process of the entire structure, the movement of the leg element (2) relative to the hydraulic element (1) is carried out around the axis of the limit pin (202), ensuring clear and efficient coordination of the movement.
[0030] exist Figures 1 to 2 In the embodiment depicted in Figure 1 The diagram shows the relationship and position of the hydraulic elements and outrigger elements in the deployed state. The auxiliary jacking legs of an all-terrain transporter include key components: hydraulic element 1 and outrigger element 2. Hydraulic element 1 comprises the following components: an upper mounting sleeve 101, an upper limit pin 102, a hydraulic cylinder 103, a piston and plunger rod 104, a lower mounting sleeve 105, a lower limit pin 106, an upper chamber 107 of the hydraulic cylinder, a lower chamber 108, and a sleeve 109. Outrigger element 2 comprises an upper mounting sleeve 201, an upper limit pin 202, a housing cover 203, a lower limit pin 204, and a movable outrigger plate 205.
[0031] The limiting sleeve 101 is a hollow cylinder that passes through the upper cavity 107 of the hydraulic cylinder 103 , plays a protective role and increases the durability of the related limiting pin 102 and hydraulic cylinder 103 components.
[0032] The hydraulic cylinder 103 is a hollow sleeve 109 with a piston and plunger rod 104, with an upper chamber 107 and a lower chamber 108, which are used to connect to other elements of the structure and transmit motion. The upper end of the hydraulic cylinder 103 is connected to the machine body using an upper mounting sleeve 101 and an upper limit pin 102, while the lower end is connected to the leg element 2 using a lower mounting sleeve 105 and a lower limit pin 106.
[0033] The housing cover 203 is a part of the leg element 2 and is very important for the construction of the off-road vehicle auxiliary lifting leg. This cover as a body element serves as an arm in the leg system.
[0034] The housing cover 203 is equipped with a series of holes 206 for mounting sleeves with stop pins. These symmetrical pairs of holes 206 are located on the left and right sides of the housing. These holes are used to connect other components and parts of the support leg. The upper hole 206 is used to mount the upper mounting sleeve 201 and the upper stop pin 202. The lower hole is used to connect the hydraulic element 1 to the support leg element 2 via the lower mounting sleeve 105 and the lower stop pin 106. The bottom hole of the housing cover 203 is connected to the movable support leg plate 205 via the stop pin 204.
[0035] When hydraulic element 1 is moved from its supported position, the hydraulic lock supporting the folded position is first unlocked. Then, the plunger rod 104 of hydraulic cylinder 103 is pushed along the axis of the sleeve. The plunger rod transmits this motion to the mounting sleeve 105 connected to the housing cover 203. The outrigger element 2, pushed by the hydraulic cylinder plunger rod 104, begins to rotate around the axis of the mounting sleeve 201. This causes the auxiliary telescopic outrigger to deploy outside the vehicle body.
[0036] To fold the outriggers from the deployed position, hydraulic element 1 moves hydraulic cylinder 103. The hydraulic cylinder is connected to the outrigger 2 at its lower end via lower mounting sleeve 105 and lower stop pin 106. Hydraulic cylinder 103 fully folds, pulling outrigger 2 with it. When plunger rod 104 fully enters sleeve 109, housing cover 203 is fully integrated with the vehicle body. A hydraulic lock locks the hydraulic cylinder and secures it in the folded position.

The relevant descriptions of the effects or advantages involved in the specification may not be reflected in the actual experimental examples due to the uncertainty of specific condition parameters or other factors, and the relevant descriptions of the effects or advantages are not used to limit the scope of the utility model.
