[0052] Further, the bottom of the bent pipe body 201 is outwardly expanded; the transverse bent pipe 204 is flush with the bottom of the bent pipe body 201, so that the transverse bent pipe 204 is easier to be grabbed to open and close the door; at the same time, the transverse bent pipe 204 flush with the bottom of the bent pipe body 201 increases the control space and the boundary sense of the driving area, thereby ensuring the safety and comfort of the driver.

[0053] Further, as shown in Figure 4 , the latch assembly 3 comprises a socket body 301, a latch 303 provided with a threaded hole, and a handle 304; the socket body 301 is provided with a U-shaped sliding groove 302; the latch 303 is arranged in the socket body 301; and the handle 304 is connected with the threaded hole of the latch 303.

[0054] When opening the door, the other end of the door body 2 is separated from the latch assembly 3, and the one end of the door body 2 is rotated around the bearing seat 5 to realize opening the door.

[0055] Further, the handle 304 is provided with knurls 305, and the outer end surface of the handle 304 is a hemispherical body 306, so as to avoid injury caused by accidental collision of personnel; in some other embodiments, a rubber spherical body is arranged on the hemispherical body 306, so as to relieve the pain when the personnel accidentally collide.

[0056] The shape of the knurls 305 is straight lines or net lines, so as to increase the friction force of the control, and make it not easy to be separated from the hand.

[0059] Further, the door body part 2 and the ceiling 1 are provided with a travel switch bracket 4, and the travel switch bracket 4 is located at the top of the ceiling 1. Figure 5 As shown in the drawings, the travel switch bracket 4 is an L-shaped bent plate, one side of the L-shaped bent plate is provided with a long hole 401, and the other side of the L-shaped bent plate is provided with a fifth mounting hole 402. The fifth mounting hole 402 is used to install a travel switch, and the travel switch is electrically connected to a buzzer alarm provided on the underground shovel loader control box; the travel switch bracket 4 is installed at the top of the ceiling 1 through the long hole 401.

[0060] Further, the door body part 2 further comprises an impact plate 205 provided at the other end of the bent pipe body 201 and located below the half shaft ear hole 203, so that when the door body part 2 is in the closed state, the impact plate 205 is attached to the travel switch. When the door body part 2 is in the open state, the impact plate 205 is separated from the travel switch, and at the same time, the travel switch sends a signal to the buzzer alarm of the electric control box, which is used to warn personnel and vehicles in the operation area, thereby ensuring the safety of the driver.

[0061] The distance value between the bottom edge of the door body part 2 and the ground of the cab is H, that is, the distance value between the bottom edge of the door body part 2 and the bottom plate 12 of the vehicle frame is H, and the H value is in the range of 950mm-1020mm. Therefore, when the door body part 2 is closed, the head and shoulder of the driver can be effectively protected, and the operation of the rear control box provided on the rear vehicle frame is not affected, so that when the cab door is opened and closed, the cab door does not interfere with the rear vehicle frame, and smooth opening and closing is realized.

[0062] As shown in the drawings, it further comprises a seat assembly 15, a pedal mounting assembly 14 and a center console 16, the seat assembly 15, the pedal mounting assembly 14 and the center console 16 are arranged in the driving space, the seat assembly 15 and the pedal mounting assembly 14 are connected with the bottom plate 12 of the vehicle frame, the seat assembly 15 faces away from the vehicle frame side plate 11, the seat assembly 15 faces the direction of the pedal mounting assembly 14, the seat assembly 15 and the pedal mounting assembly 14 are arranged in a spaced manner, and the center console 16 is arranged above the pedal mounting assembly 14, and the table top of the center console 16 is used to install a shovel control handle. Figure 9 , Figure 10 As shown in the drawings, it further comprises a seat assembly 15, a pedal mounting assembly 14 and a center console 16, the seat assembly 15, the pedal mounting assembly 14 and the center console 16 are arranged in the driving space, the seat assembly 15 and the pedal mounting assembly 14 are connected with the bottom plate 12 of the vehicle frame, the seat assembly 15 faces away from the vehicle frame side plate 11, the seat assembly 15 faces the direction of the pedal mounting assembly 14, the seat assembly 15 and the pedal mounting assembly 14 are arranged in a spaced manner, and the center console 16 is arranged above the pedal mounting assembly 14, and the table top of the center console 16 is used to install a shovel control handle.

[0063] The seat assembly 15 comprises a seat 151 and a support 152, one end of the support 152 is connected with the frame bottom plate 12, and the other end is connected with the seat 151. In the present application, the upper end surface of the support 152 and the frame bottom plate 12 have a first included angle α, wherein 0°<α<90°, that is, the end surface of the support 152 connected with the seat 151 is inclined relative to the frame bottom plate 12, and then the seat 151 and the upper end surface for contact are also inclined. When the driver sits on the seat 151, the driver's hips are lower than the knees, so that the reserved space between the driver's head and the ceiling 1 is larger, thereby improving the comfort of the driver driving.

[0064] Further, in the present application, the first included angle α is set to 5°≤α≤10°. Within this range, the reserved space from the driver's head to the ceiling 1 can be as large as possible while ensuring the comfort of the driver, and the driver can also drive smoothly and naturally.

[0065] Further, the distance between the front end surface of the seat 151 and the front end surface of the support 152 is L1, and L1 is set to be within the range of 180mm-200mm. When the driver's legs need to be curled up for rest, the lower legs and feet are collected under the seat 151 to rest and relieve fatigue.

[0066] It should be noted that in the present application, the distance between the upper surface of the front end of the seat 151 and the frame bottom plate 12 is L2, wherein 390mm≤L2≤450mm. In this way, when the driver sits on the seat 151, the included angle between the thighs and the frame bottom plate 12 is the same as the first included angle, so that the hips are low and the knees are high, thereby compressing the vertical distance between the driver's knees and the heels. That is, in the natural state, the driver's lower legs are inclined to the vertical direction, and the driver's sole surface forms an included angle with the ground, so that the driver's sole surface can better fit the pedal, so as to facilitate the driver to control the pedal and improve the use convenience and operation comfort.

[0067] It should be noted that due to the compression of the driving space, a standard seat 151 with a standard seat width of 450mm cannot be used, and a seat 151 with a seat width of 400mm is more preferably used.

[0068] The length of the human upper body ranges from 600mm to 700mm, and the height of the seat 151 is between 390mm and 450mm. This means that the total height of the driver when seated is between 990mm and 1150mm. The seat 151 is usually lower on the inside and higher on the outside, and the backrest is usually tilted, which reduces the actual total height of the driver when seated. The distance H between the bottom edge of the door body 2 and the chassis floor 12 is between 950mm and 1020mm, which means that the door body 2 will not obstruct the driver's view, making it easy for the driver to observe the sides. At the same time, when necessary, the driver can hold onto the door body 2 as an armrest while seated.

[0069] In another optional embodiment of this application, the pedal mounting assembly 14 is further extended; such as... Figure 11 As shown, the pedal mounting assembly 14 is located on the facing side of the seat 151. The pedal mounting assembly 14 includes a brake pedal base 141 and an accelerator pedal base 142. The brake pedal base 141 is used to mount the brake pedal, and the accelerator pedal base 142 is used to mount the accelerator pedal. Both the brake pedal base 141 and the accelerator pedal base 142 are mounted on the chassis base plate 12, and are spaced apart from each other. With the center line of the seat 151 as the reference line, the brake pedal base 141 and the accelerator pedal base 142 are located on both sides of the center line of the seat 151. In this embodiment, the center line of the brake pedal base 141 and the center line of the seat 151 have a second included angle θ, where 0° < θ < 90°; the center line of the accelerator pedal base 142 and the center line of the seat 151 have a fourth included angle δ, where 0° < δ < 90°. This allows the brake pedal base 141 and the accelerator pedal base 142 to be located on the extension line of the driver's legs when the driver is sitting on the seat 151, making it convenient for the driver to step on them.

[0070] Furthermore, the second included angle θ is set to 10°≤θ≤15°. Thus, the line connecting the center line of the brake pedal base 141 and the SIP center line of the seat 151 intersects, and the extension line of the side profile of the seat 151 on the side where the brake pedal base 141 is located intersects the midpoint of the front end of the brake pedal base 141. The included angle between the extension line of the side profile of the seat 151 and the center line of the brake pedal base 141 is the same as the second included angle. This ensures that when the driver operates the brake pedal, the buttocks to the knees (thighs) remain firmly against the seat of the seat 151. The reduction in the seat width of the seat 151 will not cause the buttocks to the knees to be suspended outside the seat width of the seat 151, thus ensuring the driver's operating comfort.

[0071] Further, the fourth included angle δ is set to 10°≤δ≤12°, and the fourth included angle between the center line of the accelerator pedal base 142 and the center line of the seat 151 is set to be in the range of 10°-12°. When the accelerator pedal is installed on the accelerator pedal base 142, the accelerator pedal can be prevented from interfering with the inner wall of the front frame. The cab of the present embodiment can compress a certain space and provide the compressed space to the front frame, thereby avoiding interference between the front frame and the rear frame during the whole machine steering.

[0072] Further, the first mounting groove is arranged on the frame bottom plate 12 and is used to mount the brake pedal base 141. The upper surface of the end portion of the brake pedal close to the seat 151 is lower than the upper end surface of the frame bottom plate 12, and the upper surface of the end portion of the brake pedal away from the seat 151 is higher than the upper end surface of the frame bottom plate 12. Therefore, the rear end of the brake pedal base 141 is sunken below the frame bottom plate 12, and the front end of the brake pedal base 141 is arranged on the frame bottom plate 12. When the brake pedal is installed on the brake pedal base 141, the angle of the brake pedal is matched with the included angle between the instep surface of the driver and the ground, thereby ensuring the comfort of operation.

[0073] Further, as shown in Figure 13 the upper end surface of the accelerator pedal base 142 and the frame bottom plate 12 has a third included angle β, wherein 0°<β<90°. That is, the accelerator pedal base 142 is arranged to be inclined on the frame bottom plate 12, which can increase the fit of the instep surface of the driver and the accelerator pedal, facilitate the driver to step on the accelerator pedal, and make the comfort of operation of the driver better.

[0074] Preferably, the third included angle β is set to be in the range of 8°≤β≤12°, which makes the contact between the instep surface of the driver and the accelerator pedal more comfortable and the operation better.

[0075] Further, as shown in Figure 15As shown, the installation seat 17 is connected with the bottom plate 12 at the lower end, and is connected with the center console 16 at the upper end through the connecting piece 164. The installation seat 17 is in inverted L shape, and includes a vertical plate and a horizontal plate. The horizontal plate is connected with the upper end of the vertical plate, and the included angle between the horizontal plate and the vertical plate is 90 degrees. The horizontal plate is parallel with the bottom plate 12, and the center console 16 is connected with the horizontal plate. The height of the installation seat 17 in the vertical direction is lower than the side plate 11, that is, the distance between the top of the installation seat 17 and the roof 1 is large, so that the driver's front route is not blocked. The end of the center console 16 close to the installation seat 17 is provided with a fourth mounting hole 161, and the connecting piece 164 is connected with the installation seat 17 through the fourth mounting hole 161. The connecting piece 164 is a bolt, and the height of the center console 16 can be adjusted through the fourth mounting hole 161, so that the height of the center console 16 can be adjusted, and thus the driver of different height can be adapted.

[0076] Further, as shown in the figure, Figure 12 The upper end surface of the center console 16 and the bottom plate 12 form a fifth included angle γ, wherein 0°<γ<90°, that is, in this embodiment, the center console 16 is inclined, and the table surface of the center console 16 is inclined towards the seat 151, so that the highest point of the control handle and the bucket control handle on the center console 16 is lowered and close to the driver, and the highest point of the control handle and the bucket control handle of the transmission system is kept in the comfortable operating range relative to the SIP of the seat 151. When the driver sits on the seat 151 and operates the control handle and the bucket control handle of the transmission system, the driver will not feel tired of the hands and arms due to the compression of the interior space of the cab.

[0077] Preferably, the fifth included angle γ is set in the range of 10°≤γ≤20°, which can ensure the comfort of the driver and the safety of the operation, and will not compress the arm stretching space too much.

[0078] Further, as shown in the figure, Figure 14 The top bubble rubber strip 19 is connected with the bottom outer wall of the center console 16, that is, the top bubble rubber strip 19 is arranged on the lower end surface of the center console 16. The top bubble rubber strip 19 can wrap the R corner or the sharp end of the lower end surface of the center console 16. When the driver's legs move and collide with the center console 16, the top bubble part of the top bubble rubber strip 19 is compressed and buffered, and the impact force between the legs and the bottom end of the front wall of the center console 16 is offset, so that the legs will not feel pain, and the comfort of operation is improved.
