DETAILED DESCRIPTION

[0080] The technical solutions provided by the present application will be described in detail below. Figures 1-9 The technical solutions provided by the present application will be described in detail below.

[0081] The embodiment of the present application provides a side door system assembly for engineering machinery, which is convenient for equipment maintenance. The side door system assembly comprises a door frame assembly 1, a door panel assembly 2, a door lock assembly 3 and a reinforcing rib assembly 4. The door frame assembly 1 comprises a cross beam 11, a first stand column 12 and a second stand column 13; the first stand column 12 is fixed to one end of the cross beam 11, and the second stand column 13 is fixed to the other end of the cross beam 11. The door panel assembly 2 is rotatably installed on the first stand column 12. The door lock assembly 3 is installed between the first stand column 12 and the door panel assembly 2. The reinforcing rib assembly 4 comprises a plurality of reinforcing ribs; each reinforcing rib is arranged parallel to the width direction of the door panel assembly 2; wherein at least one reinforcing rib is arranged on the top and the bottom of the door panel assembly 2; at least one reinforcing rib is arranged between the top and the bottom of the door panel assembly 2.

[0082] Referring to Figure 1, the door frame assembly 1 is fixedly installed on the vehicle body of the engineering vehicle. The first upright post 12 and the second upright post 13 of the door frame assembly 1 are arranged in parallel and vertically. The cross beam 11 is located at the top of the first upright post 12 and the second upright post 13, and connects the first upright post 12 and the second upright post 13 into a whole through the cross beam 11. The cross beam 11 can be fixedly welded to the first upright post 12 and the second upright post 13.

[0083] Continue to refer to Figure 1 , in some embodiments, the door frame assembly 1 further includes a bottom beam 14. The cross beam 11, the first upright post 12, the second upright post 13, and the bottom beam 14 together form a rectangular frame structure. This structure is more stable and reliable.

[0084] Refer to Figures 1 to 3b , in some embodiments, the cross-sectional shape of each reinforcing rib is configured as a "ji" shape.

[0085] Specifically, the technical solution of the embodiment of the present invention determines the structure and layout position of the reinforcing ribs in the following way: The door panel assembly 2 adopts the side door stiffness topology optimization method based on modal frequency, takes the first-order torsional modal natural frequency of the door panel assembly 2 as the response target, takes the layout position of the reinforcing ribs as the design variable, and takes the side door mass as the constraint condition, and the upper limit is to increase the original mass by 10%. Through the topology optimization method, it is found that the cross-section of the reinforcing rib should cover as many areas as possible, so each reinforcing rib adopts a "ji-shaped" horizontally parallel through structure. Each reinforcing rib is connected to the door panel assembly 2 by resistance welding, and the corresponding parts of each reinforcing rib and the door panel assembly 2 together form a closed structure. In some embodiments, 2 groups of reinforcing ribs are arranged in the middle of the door panel assembly 2, and 1 group of reinforcing ribs is arranged at the top and bottom of the door panel assembly 2 respectively.

[0086] In some embodiments, at least one reinforcing rib has the same length as the width of the door panel assembly 2. Specifically, all the reinforcing ribs have the same length as the width of the door panel assembly 2.

[0087] The above technical solution, based on the side door stiffness topology optimization method based on modal frequency, fully considers the layout form and position of the reinforcing ribs, improves the side door stiffness, and reduces the torsional displacement deformation of the side door; each reinforcing rib adopts a transverse "ji-shaped" horizontally through reinforcing closed structure, which greatly enhances the stiffness and structural stability of the side door system assembly, so that when the side door system of the whole vehicle is in the closed state, even if it is subjected to a relatively large impact, the side door system assembly is not easy to twist and deform.

[0088] Refer to Figure 1 and Figure 4 , door lock assemblies 3 are installed at both the upper and lower ends of the second upright post 13. The two door lock devices are configured to be linked, so as to realize the locking action of the two door lock assemblies 3 through one mechanism. As the door panel assembly 2 is closed, the door lock assembly 3 automatically locks.

[0089] With reference to Figure 4 , the door lock assembly 3 comprises a lock catch 31, a lock post 32 and an adjusting assembly 33. The lock catch 31 is rotatably mounted on the door panel assembly 2; the lock post 32 is connectable with the lock catch 31. The adjusting assembly 33 is fixed on the second upright column 13; the lock post 32 is movably mounted on the adjusting assembly 33 to adjust the position of the lock post 32 relative to the lock catch 31. The lock catch 31 and the lock post 32 are clamped to each other to achieve locking. The adjusting assembly 33 is used to fine-tune the position of the lock post 32, so that the lock post 32 better matches the lock catch 31. The adjusting assembly 33 uses a purely mechanical way to fine-tune the position of the lock post 32.

[0090] In some embodiments, the adjusting assembly 33 comprises a first guide 331, a second guide 332, a first sliding piece 333 and a second sliding piece 334. The first guide 331 is fixed on the second upright column 13, and can be welded, and is configured to provide guidance in a first direction. The second guide 332 is also fixed on the second upright column 13, and can also be welded, and is configured to provide guidance in a second direction; the first direction and the second direction intersect. The first direction is, for example, the horizontal direction as shown in Figure 4 , and the second direction is, for example, the vertical direction as shown in Figure 4 . The first guide 331 and the second guide 332 each provide guidance in one direction for the lock post 32. The movement distance of the lock post 32 is not very large, and the length of the guidance provided by the first guide 331 and the second guide 332 is limited to meet the movement path of the lock post 32.

[0091] The first sliding piece 333 is hinged to the lock post 32, and is slidably arranged in the first guide 331 along the first direction. The second sliding piece 334 is also hinged to the lock post 32, and is slidably arranged in the second guide 332 along the second direction. According to the actual installation position of the first sliding piece 333 and the second sliding piece 334, the first sliding piece 333 and the second sliding piece 334 are adjusted in position in the respective first guide 331 and second guide 332 to adapt to the horizontal and vertical directions.

[0092] The above technical solution can achieve adaptive and small displacement adjustment of the lock post 32 to compensate for manufacturing and assembly errors.

[0093] With reference to Figure 1 , Figure 5 and Figure 6 , the side door system assembly further comprises a hinge assembly 5. Along the length direction of the first upright column 12, a plurality of hinge assemblies 5 are arranged dispersedly. Specifically, five groups are provided, and each group has two hinge assemblies 5.

[0094] The hinge assembly 5 is used to realize the rotatable connection of the door panel assembly 2 and the door frame assembly 1. All the hinge assemblies 5 can adopt the scheme provided by the embodiment of the present application, or only the hinge assembly 5 located in the middle position can adopt the method of the embodiment of the present application, and the other hinges can adopt the existing structure without the limiting function.

[0095] Referring to Figure 5 , the hinge assembly 5 comprises a support seat 51, a pin shaft 52, a rotating plate 53 and a limiting tongue 54.

[0096] The support seat 51 is fixedly connected with the first upright column 12; the support seat 51 comprises a body 511, a protruding part 512 and a limiting block 513; the protruding part 512 comprises a pair of protruding parts, one of which is arranged at the top end of the body 511, and the other of which is arranged at the bottom end of the body 511. The support seat 51 is roughly plate-shaped, and the protruding part 512 is formed at both ends of the plate to install the pin shaft 52. A vertical plate can be arranged on the plate, which provides space for the rotation of the rotating plate 53, and further plays a limiting role to prevent the rotating plate 53 from rotating too much.

[0097] The pin shaft 52 is installed between the pair of protruding parts 512. The rotating plate 53 is fixedly connected with the door panel assembly 2; the limiting tongue 54 is fixedly connected with the rotating plate 53; wherein, when the door panel assembly 2 is in the closed state, the limiting tongue 54 is inserted into the limiting slot 513a. The rotating plate 53 and the limiting tongue 54 can be integrally formed, and the limiting tongue 54 protrudes outward from the edge of the rotating plate 53.

[0098] The limiting block 513 is fixed to the body 511; the limiting block 513 is provided with the limiting slot 513a. The limiting block 513 is a rubber block or a metal block. Its shape is not required, and the limiting slot 513a is located on the rotating path of the rotating plate 53 and can be inserted into the limiting slot 513a.

[0099] The hinge assembly 5 of the above technical scheme not only realizes the rotatable connection of the door panel assembly 2 and the door frame assembly 1, but also automatically realizes the cooperation of the limiting tongue 54 and the limiting slot 513a after the door panel assembly 2 is closed, thereby increasing the constraint of the door panel assembly 2 and the door frame assembly 1, so that even if the side door system assembly is subjected to a relatively large impact in the closed state, the torsional deformation is not easy to occur, and the fatigue life of the side door system assembly is increased.

[0100] Referring to Figure 1 , Figures 6 to 8 In some embodiments, the side door system assembly further comprises a limiting assembly 6. The limiting assembly 6 is used to play a limiting role when the door panel assembly 2 is in the closed state. The limiting assembly 6 is installed between the door panel assembly 2 and the second upright column 13; the limiting assembly 6 is configured to automatically fix the door panel assembly 2 and the second upright column 13 when the door panel assembly 2 is closed.

[0101] Two limiting assemblies 6 are arranged along the height direction of the door panel assembly. The limiting assembly 6 and the hinge assembly 5 at the middle position of the height direction of the door panel assembly 2 jointly form an ABC three-point arrangement, as shown in Figure 6 The three-point limiting formed by the two limiting assemblies 6 and the hinge assembly 5 enables the limiting of the door panel assembly 2 by the limiting assembly 6 and the hinge assembly 5 to cooperate with each other, forming a multi-degree-of-freedom strong constraint structure of the side door assembly system, which provides more directional limiting for the door panel assembly 2, so that the door panel assembly 2 can be constrained in six directions in the closed state, greatly improving the vibration fatigue life of the side door system assembly.

[0102] Referring to Figure 5 and Figure 6 , the limiting assembly 6 includes a fixed block 61, a mounting seat 62, a first clamping piece 63, a second clamping piece 64, a deformable piece 65, and an elastic piece 66. The fixed block 61 is fixed to the second upright column 13. The mounting seat 62 is fixed to the door panel assembly 2. The first clamping piece 63 is rotatably mounted to the mounting seat 62, and the first clamping piece 63 includes a first open slot 630. The second clamping piece 64 is rotatably mounted to the mounting seat 62, and the second clamping piece 64 includes a second open slot 640. The opening directions of the first open slot 630 and the second open slot 640 are opposite to each other to form a clamping groove for clamping the fixed block 61. One end of the deformable piece 65 is fixedly connected to the side of the first clamping piece 63 facing the second clamping piece 64, and the other end of the deformable piece 65 is fixedly connected to the side of the second clamping piece 64 facing the first clamping piece 63. The elastic piece 66 is mounted between the deformable piece 65 and the mounting seat 62 to realize the resetting of the first clamping piece 63 and the second clamping piece 64.

[0103] The fixed block 61 is made of rubber, and the first clamping piece 63 and the second clamping piece 64 are made of nylon, for example. The fixed block 61 made of rubber has a certain deformation amount on the surface in contact with the first clamping piece 63 and the second clamping piece 64.

[0104] In some embodiments, the deformable piece 65 includes a steel sheet, and / or the elastic piece 66 includes a spring. The deformable piece 65 is originally arc-shaped and can become flat under the extrusion of the fixed block 61.

[0105] In some embodiments, the first clamping piece 63 includes a first plate 631 and a second plate 632. The second plate 632 intersects with the first plate 631 and is fixedly connected thereto. The first plate 631 or the second plate 632 is rotatably connected to the mounting seat 62. Specifically, the rotatable connection is realized through a first hinge seat 634. The first clamping piece 63 and the second clamping piece 64 can both be L-shaped plates.

[0106] In some embodiments, the second clamping piece 64 comprises a third plate 641, a fourth plate 642, and a second clamping block 643. The third plate 641 is arranged adjacent to the mounting base 62. The fourth plate 642 intersects and is fixedly connected with the third plate 641. The second clamping block 643 is fixed to the third plate 641. The second opening slot 640 is provided in the second clamping block 643. The third plate 641 or the fourth plate 642 is rotatably connected with the mounting base 62. The rotatable connection is specifically achieved by a second hinge seat 644.

[0107] In some embodiments, the fixed block 61 is polygonal in cross section, specifically hexagonal. The bottom dimension of the first opening slot 630 is smaller than the top dimension of the first opening slot 630; and / or, the bottom dimension of the second opening slot 640 is smaller than the top dimension of the second opening slot 640. The first opening slot 630 and the second opening slot 640 adopt a trapezoidal opening.

[0108] The above technical solution, through cooperation of the fixed block 61 and the first clamping piece 63 and the second clamping piece 64, achieves 6-way omnidirectional limiting. The contact surface shape of the fixed block 61 and the first clamping piece 63 and the second clamping piece 64 is designed as a circular arc shape, so as to achieve that, after the fixed block 61 contacts the deformable piece 65, the fixed block 61 is pressed to generate mutual elastic force, forming front and rear limiting, and cooperating with the opening shape of the first clamping piece 63 and the second clamping piece 64, forming a surrounding limiting function of the upper, lower, left, and right four sides. The limiting assembly 6 cooperates with the hinge assembly 5 to achieve complete six-way limiting.

[0109] In some embodiments, the side door system assembly further comprises a sleeve 7 and a support rod 8. The sleeve 7 and the support rod 8 are installed between the first clamping piece 63 and the mounting base 62, or between the second clamping piece 64 and the mounting base 62.

[0110] Specifically, one installation mode is that one end of the sleeve 7 is installed on one of the first clamping piece 63 and the mounting base 62, and one end of the support rod 8 is installed on the other of the first clamping piece 63 and the mounting base 62. The other end of the support rod 8 is inserted into the other end of the sleeve 7, and the friction force between the support rod 8 and the sleeve 7 is configured such that the support rod 8 is positioned at any position of the sleeve 7 relative to the sleeve 7. The sleeve 7 and the support rod 8 play a role of vertical support.

[0111] Another installation mode is that one end of the sleeve 7 is installed on one of the second clamping piece 64 and the mounting base 62. One end of the support rod 8 is installed on the other of the second clamping piece 64 and the mounting base 62. The other end of the support rod 8 is inserted into the other end of the sleeve 7, and the friction force between the support rod 8 and the sleeve 7 is configured such that the support rod 8 is positioned at any position of the sleeve 7 relative to the sleeve 7. The sleeve 7 and the support rod 8 play a role of vertical support.

[0112] The support rod 8 is a friction type support rod 8, and has the functions of supporting and adjusting height, and can be locked at any position in the stroke without external structure. In actual use, the position adjustment of the side door system assembly in other directions can be realized by controlling the locked position of the stroke of the support rod 8.

[0113] The working principle of the limiting assembly 6 is introduced below.

[0114] Referring to Figure 8 , when the side door system assembly is closed, the door plate assembly 2 rotates relative to the door frame assembly 1, and each component mounted on the door plate assembly 2 also rotates synchronously, and the first clamping piece 63 and the second clamping piece 64 of the limiting assembly 6 also rotate with the door plate assembly 2. The fixed block 61 of the limiting assembly 6 is close to the first clamping piece 63 and the second clamping piece 64, as shown in Figure 8 . In the original state, the first clamping piece 63 and the second clamping piece 64 are inclined relative to the mounting seat 62 under the pulling of the deformable piece 65. The process of closing the door is from the dashed line to the solid line in Figure 8 . The first clamping piece 63 and the second clamping piece 64 enclose a clamping groove in the original state. After the fixed block 61 is inserted into the bottom of the clamping groove, the fixed block 61 contacts and compresses the deformable piece 65, the deformable piece 65 is subjected to a transverse extrusion force, and the first clamping piece 63 and the second clamping piece 64 rotate with the deformation of the deformable piece 65. After the first clamping piece 63 and the second clamping piece 64 rotate, the opening size of the clamping groove becomes smaller, the clamping groove wraps and clamps the fixed block 61, so as to realize the surrounding limiting of the fixed block 61 in the up, down, left and right four directions, and the limiting process is automatically completed with the closing operation.

[0115] In the closing process of the door plate assembly 2, the lock catch 31 of the door lock assembly 3 hooks the lock post 32. If the position of the lock post 32 cannot hook the lock catch 31, the position of the lock post 32 can be fine-tuned with the first sliding piece 333 and the second sliding piece 334, so as to realize the automatic adjustment of the position of the lock post 32.
