DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with specific examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention.

[0018] like Figure 1As shown, an embodiment of the present invention provides an armrest box for a skid loader, including an armrest box upper cover 1, an armrest box lower cover 2, a mounting bracket 1 3, a mounting bracket 2 4, a moving mechanism 5, an elbow support 6, a pull rod handle 7 and an operating handle 8.

[0019] The armrest box upper cover 1 and the armrest box lower cover 2 constitute an armrest box protection cover for accommodating the internal components of the armrest box.

[0020] like Figure 3 As shown, the moving mechanism 5 includes a pull rod handle 7 , a limiting plate 11 , an upper base 13 and a lower base 14 .

[0021] The upper base 13 is an inverted U-shaped structure as a whole, and the lower base 14 is a U-shaped structure as a whole. The upper base 13 is slidably connected to the lower base 14. A limit opening 15 is provided at the middle position of both sides of the upper base 13. Both sides of the lower base 14 are provided with flanges, and the two flanges are provided with limit teeth 16. Through the cooperation of the limit teeth 16 and the limit opening 15, the movement and locking of the armrest box can be realized.

[0022] The limiting plate 11 is fixed to one side of the upper base 13 , and the pull rod handle 7 is fixedly connected to the limiting plate 11 .

[0023] One end of the pull wire 10 is connected to the limit plate 11 , and the other end is fixed to the upper base 13 , so as to limit the movement stroke of the armrest box.

[0024] When adjusting the front and rear position of the armrest box, the driver pulls the lever handle 7, which in turn turns the limit plate 11, releases the limit buckle between the limit opening 15 and the limit tooth 16, and allows the armrest box to move forward and backward relative to the seat as a whole; when it moves to the ideal position, the lever handle 7 is released, the limit plate 11 is reset, and the limit buckle between the limit opening 15 and the limit tooth 16 is locked, completing the position movement. By moving the front and rear position of the armrest box, an elastic space is generated inside the cab to meet the operating space requirements of different drivers under different working conditions, making the driver's operation process more comfortable.

[0025] like Figure 2 As shown, a handle bracket 12 is fixedly connected to the upper base 13, an operating handle 8 is installed at the front end of the handle bracket 12, a mounting bracket 1 3 and a mounting bracket 2 4 are fixedly connected to the lower base 14, and the armrest box is fixed to the seat through the mounting bracket 1 3 and the mounting bracket 2 4.

[0026] More specifically, one end of the mounting bracket 1 3 and the mounting bracket 2 4 is fixed to the lower base 14 by bolts to ensure the stability of the moving mechanism 5. The other ends of the mounting bracket 1 3 and the mounting bracket 2 4 are fixed to the seat by bolts, so that the armrest box can float forward and backward with the seat, ensuring that the position of the human body relative to the handle is always consistent, reducing operating fatigue, and improving the accuracy and comfort of operation.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, the skid steer loader armrest box of the embodiment of the present invention further includes an elbow support flipping mechanism 18 and an electromagnetic induction device 17.

[0028] The elbow support turning mechanism 18 comprises a turning base 19, a turning bracket 20 and a turning limit mechanism.

[0029] The flip base 19 is fixed on the handle bracket 12 .

[0030] The elbow support 6 is fixed on the flip bracket 20 and has an extension portion 25 . The extension portion 25 can be used to restrict the driver from leaving the seat.

[0031] The flip bracket 20 is connected to the flip base 19 via a flip limiting mechanism, and the flip limiting mechanism is used to realize the upward flipping and lowering of the elbow support 6, and to lock the elbow support 6 when the elbow support 6 reaches the target position.

[0032] The electromagnetic induction device 17 is installed on the flip base 19. When the elbow rest 6 is lowered, the electromagnetic induction device 17 contacts the flip bracket 20 to achieve the connection of the hydraulic system. When the elbow rest 6 is raised, the contact between the electromagnetic induction device 17 and the flip bracket 20 is disconnected to achieve the locking of the hydraulic system.

[0033] like Figure 4 and Figure 5 As shown, the flip limiting mechanism includes a flip shaft 21, a flip spring 22, a flip limiting block 1 23 and a flip limiting block 24.

[0034] The flip spring 22 is arranged in the flip base 19, the flip limit block 24 is fixedly connected to the flip bracket 20, one end of the flip shaft 21 passes through the flip limit block 24 and is fixedly connected to the flip bracket 20, and the other end passes through the flip limit block 1 23 and the flip spring 22, and is movably connected to the outside of the flip base 19 through the limit stop block 30 and the limit bolt 28. One side of the flip limit block 1 23 is connected to the flip limit block 24 with a rotating buckle, and the other side is blocked on the inner wall of the flip base 19.

[0035] When the elbow rest 6 is lifted or lowered, the flip limit block 24 rotates, releasing the snap connection with the flip limit block 1 23, driving the flip shaft 21 to rotate, and at the same time pushing the flip limit block 1 23 to compress the flip spring 22. When the elbow rest 6 is flipped to the target position, the elbow rest 6 is released, and the flip limit block 1 23 moves toward the flip limit block 24 under the action of the flip spring 22 and is snap-connected with the flip limit block 24, thereby locking the elbow rest 6.

[0036] Among them, Figure 5As shown, the flip limit block 1 23 is provided with a plurality of limit slots 26 along the circumferential direction, and the flip limit block 2 24 is provided with a plurality of limit teeth 27 cooperating with the limit slots 26 along the circumferential direction, so as to realize the rotational snap connection between the flip limit block 1 23 and the flip limit block 2 24 .

[0037] like Figure 2 As shown, the elbow support 6 includes an elbow support pad 29 and an elbow support bracket 9. The elbow support pad 29 is fixed on the elbow support bracket 9, and the elbow support bracket 9 is fixed on the flip bracket 20.

[0038] The elbow support pad 29 is integrally formed by a foaming process, and has good support and high comfort.

[0039] The elbow rest 6 has the function of flipping over to lock and protect the hydraulic system of the whole machine. When the driver leaves the seat, the elbow rest must be flipped up to cut off the power immediately after leaving the seat, avoiding the danger caused by the driver forgetting to turn off the hydraulic system after leaving the seat. When the driver gets up and leaves the seat, the elbow rest 6 must be flipped up to achieve the action of getting up. Therefore, under normal operation, flipping up the elbow rest 6 is a necessary action to leave the cab. When the elbow rest 6 is flipped up, the electromagnetic induction device 17 is linked to sense, and the hydraulic system of the whole vehicle is locked to ensure that the whole machine is in a non-starting state when the driver leaves the cab. This can avoid the danger of accidental collision caused by the driver getting off the vehicle without turning off the hydraulic system, and protect the safety of the driver, on-site construction personnel and the whole machine.

[0040] At the same time, when the working conditions are more complicated, such as steep slopes or bumps, the extended portion 25 of the elbow rest can also form a semi-suspended support point in front of the driver, which can block and support the driver when the driver leans forward, thereby improving safety performance.

[0041] The armrest box of the skid loader provided by the present invention can be moved forward and backward relative to the seat, so as to meet the operating space requirements of different drivers under different working conditions and improve driving comfort; the elbow rest is provided with an extension part, so that the driver must flip the elbow rest before leaving the seat. After flipping, the electromagnetic induction device is disconnected, so that the hydraulic system of the whole machine is locked, and the function of locking the hydraulic system immediately when the driver leaves the seat is realized, thereby avoiding the danger caused by the driver forgetting to turn off the hydraulic system when leaving the seat; at the same time, the elbow rest extension forms a guardrail, which has a protective support function and improves the safety of the driver.

[0042] In another embodiment, the present invention further provides a skid steer loader, comprising the aforementioned skid steer loader armrest box.

[0043] The present invention has been disclosed above with preferred embodiments, but they are not intended to limit the present invention. Any technical solutions obtained by adopting equivalent replacement or equivalent transformation solutions fall within the protection scope of the present invention.
