A through passage

Abstract

This invention discloses a through passageway, comprising two half-windshield assemblies locked together by a locking mechanism. A side guard support assembly is mounted on the body frame of each half-windshield assembly. The side guard assembly includes a middle guard plate assembly, an overlapping guard plate assembly, and side guard plate assemblies. The middle guard plate assembly has a wear-resistant layer that slides with the overlapping guard plate assembly. The overlapping guard plate assembly has a pin seat body and an overlapping guard plate mounting shaft. The pin seat body is mounted on and protrudes from the overlapping guard plate assembly. A wear plate that slides with the middle guard plate assembly is provided on the protrusion. The overlapping guard plate mounting shaft is located between the wear plate on the protrusion and the overlapping guard plate assembly. During the contraction or extension of the side guard plate, the force acting on the overlapping guard plate mounting shaft will not cause the overlapping guard plate assembly to rotate horizontally, thus preventing collisions between the overlapping guard plate assembly and other components and ensuring the service life of the side guard plate and the through passageway.

Description

Technical Field

[0001] This invention belongs to the field of rail transit equipment technology, specifically, it relates to a through passageway. Background Technology

[0002] With the rapid development of my country's rail transit industry, the types of rail vehicles are gradually increasing. As an important component connecting the car bodies, the structure of the connecting passage is also constantly increasing to meet the requirements of diverse road conditions. Among them, the side guard plate is an important part of the internal passage of the connecting passage, providing side protection for the passage between the car ends. In order to take into account the requirements of large car end distances and small curve paths, the side guard plate often adopts a multi-piece structure, such as a five-piece structure.

[0003] like Figure 1 The diagram shows a five-piece side panel assembly, including a middle side panel 300, a first side panel 100, a second side panel 200, a first side panel 400, and a second side panel 500, which are linked by a linkage mechanism 600. The first side panel 100 and the second side panel 200 are mounted on the through channel via a mounting base 110. Wear plates 800 are installed between the side panels. The extension and retraction direction of the linkage mechanism 600 is 610. During the retraction process, the linkage mechanism 600 exerts opposing thrusts on the first side plate 400 and the second side plate 500. Since one end of the first side plate 400 is in contact with the first side plate 100 only through the wear plate 800, and the second end of the first side plate 400 is assembled with the linkage mechanism 600 through the L-shaped mounting seat, the first side plate 400 will also rotate horizontally under the action of the thrust (arrow direction in the figure). Similarly, during the extension and retraction process of the linkage mechanism 600, the first side plate 400 will also rotate in the opposite direction of the arrow in the figure. Therefore, the side plate has poor stability when it moves and will collide with adjacent plates or the linkage mechanism, resulting in damage to the side plate and shortening its service life.

[0004] In addition, due to the assembly method of the first side plate 400 and the L-shaped mounting base of the linkage mechanism, the width of the first side plate 400 is relatively wide, and it must overlap with the rotation part of the linkage mechanism assembled with it, resulting in a large weight of the entire side plate.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] This invention proposes a through channel, which solves the technical problem that when the side guards of the through channel form an intermediate guard and the adjacent guards adjacent to the intermediate guard are only slidably connected by a wear layer, the adjacent guards will rotate horizontally when the side guards shrink or stretch, collide with other components, and cause damage to the side guards, thus shortening the service life of the side guards.

[0020] As described above, the vehicle body frame assembly is equipped with a brush assembly.

[0021] As described above, the through channel includes a coupler support plate, and a coupler wear plate is provided at the bottom of the docking frame.

[0022] As described above, the bottom of the vehicle body frame is provided with a centering pin in the through passage.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are as follows: A through passage includes a half-windshield assembly, a side guard plate assembly, a pedal assembly, and a roof assembly. The half-windshield assembly includes a folding canopy assembly, a vehicle frame assembly, and a docking frame assembly. The docking frame assemblies of two half-windshield assemblies are locked by a locking assembly. A side guard plate support assembly is provided on the vehicle frame assembly. The side guard plate assembly includes a middle guard plate assembly linked by a linkage assembly, two overlapping guard plate assemblies, and two side guard plate assemblies. The overlapping guard plate assemblies are located between the middle guard plate assembly and the side guard plate assemblies, and overlap with the middle guard plate assembly and the side guard plate assemblies. A wear-resistant middle guard plate layer that slides with the overlapping guard plate assembly is provided at the overlapping portion of the middle guard plate assembly. The middle guard plate assembly includes a middle guard plate mounting shaft assembled with the linkage assembly. A pin seat assembly is provided at the overlapping portion of the guard plate assembly and the intermediate guard plate assembly. The pin seat assembly includes a pin seat body and an overlapping guard plate mounting shaft. The pin seat body is mounted on the overlapping guard plate assembly and has a protruding portion protruding from the overlapping guard plate assembly. A wear plate is provided on the protruding portion, and the wear plate is in sliding engagement with the intermediate guard plate assembly. The overlapping guard plate mounting shaft is assembled with a connecting rod assembly, and the overlapping guard plate mounting shaft is located between the wear plate and the overlapping guard plate assembly on the protruding portion. A wear-resistant layer of the overlapping guard plate is provided at the overlapping portion of the overlapping guard plate assembly and the side guard plate assembly, and is in sliding engagement with the side guard plate assembly. The side guard plate assembly includes a connecting rod assembly mounting seat and a shaft seat assembly. The connecting rod assembly mounting seat is assembled with the connecting rod assembly, and the shaft seat assembly is assembled with the side guard plate support assembly. The connecting rod assembly mounting seat, the overlapping guard plate mounting shaft, and the intermediate guard plate mounting shaft are arranged in the extension and retraction direction of the connecting rod assembly. The side guard plate of the through passage of the present invention has a wear plate that slides and engages with the middle guard plate on the protruding part of the pin seat body and the overlapping guard plate. A wear-resistant layer of the middle guard plate that slides and engages with the overlapping guard plate is provided at the overlapping part of the middle guard plate and the overlapping guard plate. The mounting shaft of the overlapping guard plate, which is assembled with the connecting rod, is located between the wear plate on the protruding part and the overlapping guard plate. Therefore, during the shrinking or stretching of the side guard plate, since there are wear parts on both sides of the mounting shaft of the overlapping guard plate that slide and engage with the middle guard plate, the force acting on the mounting shaft of the overlapping guard plate will not cause the overlapping guard plate to rotate horizontally. This can prevent the overlapping guard plate from colliding with other components, avoid damage to the side guard plate, ensure the service life of the side guard plate, and ensure the quick installation and service life of the through passage.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0066] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0067] like Figure 18-20 As shown, a through passage includes a half windshield assembly 100, a side guard plate assembly, a pedal assembly 200, a top plate assembly 300, a brush assembly 5, a coupler support plate 7, and a centering pin 1022.

[0068] The system comprises two half-windshield components 100; two side guard plate components; two pedal components 200; two roof plate components 300; four brush components 5 (two on the left and two on the right); two coupler support plates 7; and two centering pins 1022. Each half-windshield component 100 corresponds to one pedal component 200 (located on the inner bottom of the passageway), one roof plate component 300 (located on the inner top of the passageway), two brush components 5, one coupler support plate 7 (located on the outer bottom of the passageway), and one centering pin 1022. After the two half-windshield components 100 are joined together, the two side guard plate components are located on the left and right sides of the passageway, respectively.

[0069] The half windshield assembly 100 includes a folding canopy assembly 101, a body frame assembly 102, a docking frame assembly 103, a transition plate assembly 104, two tension springs assembly 105, and four side guard plate supports assembly 106.

[0070] The folding canopy assembly 101 is installed together with the docking frame assembly 103, and a sealing strip is installed between the end frame of the folding canopy assembly and the docking frame assembly 103. The folding canopy assembly 101 is installed together with the vehicle body frame assembly 102, and a sealing strip is installed between the end frame of the folding canopy assembly and the vehicle body frame assembly 102. The sealing strip can ensure the airtightness of the half windshield assembly 100.

[0071] The ferrule assembly 104 is installed on the docking frame assembly 103.

[0072] The vehicle body frame assembly 102 is provided with a side guard plate support assembly 106, which is used to install the side guard plate assembly.

[0073] Specifically, a mounting plate 1021 is installed on the vehicle body frame assembly 102, and a side guard plate support assembly 106 is installed on the mounting plate 1021.

[0074] like Figure 20-21As shown, both the body frame assembly 102 and the docking frame assembly 103 are provided with tension spring rope seats 1051, and the tension spring assembly 105 is assembled with the tension spring rope seats 1051 through bushing 1052 and pin 1053.

[0075] The tension spring assembly 105 ensures the alignment of the two half windshield assemblies 100 in the direction of vehicle travel.

[0076] like Figure 22 As shown, the docking frame assembly 103 is equipped with a guide head 1031 and a guide seat 1032. The guide seats 1031 and guide heads 1032 on the two docking frame assemblies 103 are mated together. The guide seats 1031 and guide heads 1032 work together to ensure that the two docking frame assemblies 103 do not shift.

[0077] like Figure 22-24 As shown, the docking frame consisting of two half windshields 100 is locked by the lock assembly 1035.

[0078] One of the two docking frame components 103 is provided with a lock assembly groove 1033 and a lock mounting plate 1034. The lock mounting plate 1034 is used to restrict the lock assembly 1035 within the lock assembly groove 1033. The other docking frame component 103 is provided with a lock hook plate.

[0079] The lock assembly 1035 includes a first lock body 10351 and two second lock bodies 10352 at a certain angle to the first lock body 10351. Each of the first and second lock bodies 10351 is equipped with a lock hook 10353. Multiple rigid connecting sections 10354 are provided between the first and second lock bodies 10351 and 10352, and these rigid connecting sections 10354 are rotatably connected. The multiple rigid connecting sections 10354 are located at the corners of the mating frames, allowing for slight deformation during locking and unlocking processes.

[0080] The 1035 lock has a simple structure, is easy to assemble, and has a smooth locking and unlocking process.

[0081] A lock support 10383 is installed on the docking frame 103. The lock handle 10381 is rotatably connected to the lock support 10383. The lock connecting rod 10382 is rotatably connected to the first lock body 10351 and the lock handle 10381. The rotation of the lock handle 10381 drives the first lock body 10351 and the second lock body 10352 to move through the lock connecting rod 10382, so that the lock hook 10353 locks or unlocks with the lock hook plate.

[0082] To ensure the locked state, a handle locking device is provided on the docking frame assembly 103. The handle locking device includes a lock cover 1036 and a rotary latch 1037 located on the lock cover 1036. The lock cover 1036 is rotatably mounted on the docking frame assembly 103 to rotate to an open state and a locked state. In the locked state, the rotary latch 1037 rotates to cooperate with a baffle on another docking frame assembly 103 to fix the lock cover 1036.

[0083] The locking mechanism of the lock assembly is as follows: Press down on the lock handle 10381, and the lock assembly 1035 will slide counterclockwise through the lock linkage 10382.

[0084] After the lock handle 10381 is fully pressed down, the lock hook 10353 locks with the lock hook plate, closes the lock cover 1036, and rotates the rotary latch 1037 to lock with the baffle on the mating frame assembly 103, locking the lock handle 10381 inside the lock cover 1036, preventing the lock assembly 1035 from being opened accidentally, thus ensuring the locking safety of the entire passageway.

[0085] The sealing strip is installed inside the mating side groove of the mating frame assembly 103 and runs through the circumference of the mating frame assembly 103, ensuring the sealing of the entire through channel after the mating is completed.

[0086] like Figure 25-26 As shown, the connecting passage includes a coupler support plate 7, which is fixed to the coupler. A coupler wear plate 1039 is provided at the bottom of the docking frame assembly 103. The coupler wear plate 1039 is U-shaped and located on the coupler support plate 7. The coupler wear plate 1039 is made of wear-resistant and noise-reducing material, wrapping around the interconnected profiles to ensure that the connecting passage does not generate noise during vehicle operation.

[0087] The coupler support plate 7 is provided with a protrusion 71, which is located between the coupler wear plate 1039 of the two docking frames 103. The mating surface between the protrusion 71 and the coupler wear plate 1039 is an arc surface.

[0088] After the connecting passage is installed with the car body, the two coupler wear strips 1039 are located on the upper surface of the coupler support plate 7, respectively on both sides of the protrusion 71. This installation method ensures that the docking frame assembly 103 is always located in the middle position of the connecting passage. The protrusion 71 ensures that during the operation of the entire connecting passage, especially when passing through curved tracks, the docking frame assembly 103 only swings slightly around the protrusion 71, without causing a large-scale deviation, thus ensuring the safety of passengers and other personnel and increasing the service life of the connecting passage.

[0089] A centering pin 1022 is provided at the bottom of the body frame assembly 102. During the installation of the entire through passage, the threaded end of the centering pin 1022 is installed on the end wall of the body, and the unthreaded end of the body frame assembly 102 and the centering pin 1022 cooperate with each other. The centering pin 1022 increases the ease of installation between the body frame assembly 102 and the end wall of the body. The two opposing mating frame assemblies 103, after cooperating with the upper guide seat 1032 and guide head 1031, ensure the horizontal centering of the two mating half windshield assemblies 1 on the body.

[0090] A brush assembly 5 is mounted on the body frame assembly 102 and is installed on the mounting plate 1021. The brush assembly includes a clamping profile, a brush, and a bracket. The clamping profile clamps the brush and is mounted on the mounting plate 1021 via the bracket. The brush assembly 5 is used to prevent passengers and other personnel from accidentally inserting their body parts into the gap between the side guard plate assembly 4 and the end wall of the vehicle body, ensuring the safety of passengers and other personnel.

[0091] The side guards consist of five panels, which can accommodate both large vehicle end distances and the requirements for passing through narrow curves.

[0092] like Figure 2-17 As shown, the side guard plate consists of a connecting rod assembly 4, a middle guard plate assembly 3, two overlapping guard plates assembly 2, and two side guard plates assembly 1.

[0093] The intermediate guard plate assembly 3, the overlapping guard plate assembly 2, and the side guard plate assembly 1 are linked together by the connecting rod assembly 4. The overlapping guard plate assembly 2 is located between the intermediate guard plate assembly 3 and the side guard plate assembly 1, and the overlapping guard plate assembly 2 partially overlaps with the intermediate guard plate assembly 3 and the side guard plate assembly 1.

[0094] Specifically, the intermediate protective panel assembly 3, the overlapping protective panel assembly 2, and the side protective panel assembly 3 are arranged in the left-right direction in the diagram. The intermediate protective panel assembly 3 forms the outermost layer of the side protective panels. The two overlapping protective panel assemblies 2 are located inside the intermediate protective panel assembly 2, forming the second outermost layer of the side protective panels. The two overlapping protective panel assemblies 2 partially overlap with the left and right sides of the intermediate protective panel assembly 3, and some overlapping protective panel assemblies 2 are exposed outside the intermediate protective panel assembly 3. The two side protective panel assemblies 1 are located inside the intermediate protective panel assembly 2, forming the third outermost layer of the side protective panels. The two side protective panel assemblies 1 partially overlap with the overlapping protective panel assemblies 2, and some side protective panel assemblies 1 are exposed outside the overlapping protective panel assemblies 2.

[0095] Linkage assembly 4 is located inside the side guard plate and is rotatably connected to the middle guard plate assembly 3, the overlapping guard plate assembly 2, and the side guard plate assembly 1. The middle guard plate assembly 3, the overlapping guard plate assembly 2, and the side guard plate assembly 3 are assembled together via linkage assembly 4.

[0096] like Figure 2-10As shown, the overlapping portion of the intermediate guard plate assembly 3 and the overlapping guard plate assembly 2 is provided with an intermediate guard plate wear-resistant layer 35 that slides in cooperation with the overlapping guard plate assembly 2. The intermediate guard plate wear-resistant layer 35 can prevent mutual wear during the relative movement of the intermediate guard plate assembly 3 and the overlapping guard plate assembly 2. Two intermediate guard plate wear-resistant layers 35 are provided on the intermediate guard plate assembly 3.

[0097] The intermediate guard plate assembly 3 includes an intermediate guard plate body 31, which is specifically a profile. The two sides of the intermediate guard plate body 31 are bent inwards to form a bending surface 3121. An intermediate guard plate wear-resistant layer mounting plate 3122 is located on the inner side of the intermediate guard plate body 31, and the mounting plate 3122 is in contact with the bending surface 3121. The mounting plate 3122 is opposite to the intermediate guard plate body 31, and is in contact with the inner side of the intermediate guard plate body 31. Generally, the intermediate guard plate body 31, the bending surface 3121, and the mounting plate 3122 are integrally formed profiles. The mounting plate 3122, the intermediate guard plate body 31, and the mounting plate 3122 form a cavity, which can reduce the weight of the intermediate guard plate assembly 3.

[0098] Since the middle guard plate body 31 is generally quite wide, in order to facilitate processing, the middle guard plate body 31 includes a middle plate 311 and two side plates 312. The middle plate 311 includes an inward folding mounting part 3111, which is assembled with the inner surface of the side plate 312. The outer surface of the middle plate 311 and the outer surface of the side plate 312 are connected and flush.

[0099] The wear-resistant layer mounting plate 3122 of the intermediate guard plate and the bending surface 3121 of the intermediate guard plate body are both located on the side plate 312.

[0100] The intermediate guard plate assembly 3 includes a mounting base 32 and an intermediate guard plate mounting shaft 321 assembled with the connecting rod assembly 4.

[0101] Mounting base 32 is mounted on intermediate guard plate body 31, intermediate guard plate mounting shaft 321 is located on mounting base 32, intermediate guard plate mounting shaft 321 is perpendicular to intermediate guard plate body 31, especially perpendicular to middle plate 311.

[0102] When the intermediate guard plate assembly 3 is assembled with the connecting rod assembly 4, a sleeve is installed on the mounting shaft 321. After the mounting shaft 321 passes through the mounting hole on the connecting rod assembly 4, washers, compression springs, and washers are installed on the mounting shaft 321 in sequence. Finally, fasteners are installed. In some embodiments, the fasteners are slotted nuts and cotter pins. The cotter pin needs to pass through the slot of the slotted nut and the hole at the end of the mounting shaft 321.

[0103] Mounting base 32 is located between the two intermediate protective plates and wear-resistant layers 35.

[0104] Generally, a middle guard plate assembly 3 includes two sets of mounting seats 32 arranged in the vertical direction.

[0105] The middle guard plate component 3 also includes middle guard plate skirts 33, with the two middle guard plate skirts 33 located at the upper and lower ends of the middle guard plate body 31.

[0106] The middle guard plate assembly 3 may also include a lifting plate 34, which is installed on the inner side of the middle guard plate body 31.

[0107] To facilitate the assembly of the intermediate guard plate body 31 with other components, an intermediate guard plate body slide groove 313 is provided on the intermediate guard plate body 31, which passes through the upper and lower ends of the intermediate guard plate body 31.

[0108] A middle guard plate body groove 313 is provided on both the middle plate 311 and the side plate 312.

[0109] Mounting base 32 is fixed to the middle guard plate body slide groove 313 of the middle plate 311 and the side plate 312 by fixing components; the inner folding mounting part 3111 of the middle plate 311 is fixed to the middle guard plate body slide groove 313 of the side plate 312 by fixing components; the middle guard plate skirt 33 is fixed to the middle guard plate body slide groove 313 of the middle plate 311 and the side plate 312 by fixing components; the lifting plate 34 is fixed to the middle guard plate body slide groove 313 of the middle plate 311 by fixing components.

[0110] The fixing components include screws, washers, and a slider located in the slide groove 313 of the intermediate guard plate body, with the screws and slider threaded together. This method facilitates assembly.

[0111] like Figure 11-14 As shown, a pin seat assembly is provided at the overlapping part of the overlapping guard plate assembly 2 and the intermediate guard plate assembly 3. The pin seat assembly includes a pin seat body 24 and an overlapping guard plate mounting shaft 241.

[0112] The pin seat body 24 is mounted on the overlapping guard plate assembly 2 and has a protrusion that protrudes from the overlapping guard plate assembly 2.

[0113] Specifically, the pin seat body 24 is a flat, elongated strip. One end of the pin seat body 24 is installed inside the overlapping guard plate assembly 2, overlapping with the overlapping guard plate assembly 2. The pin seat body 24 installed inside the overlapping guard plate assembly 2 may also be provided with weight-reducing holes to reduce the weight of the side guard plate. The other end of the pin seat body 24 protrudes from the overlapping guard plate assembly 2 and does not overlap with the overlapping guard plate assembly 2. The pin seat body 24 is parallel or substantially parallel to the overlapping guard plate assembly 2.

[0114] A wear plate 26 is provided on the protrusion of the pin seat body 24, and the wear plate 26 and the intermediate guard plate form a sliding fit.

[0115] Specifically, the mounting position of the pin seat body 24 corresponds to the mounting base 32, so that the mounting position of the wear plate 26 corresponds to the mounting base 32, and the wear plate 26 and the mounting base 32 slide together.

[0116] The protrusion has an end that is away from the overlapping guard plate assembly 2, and the wear plate 26 is located at the end, so that the distance between the wear plate 26 and the wear-resistant layer 35 of the intermediate guard plate is as large as possible, so as to maximize the stability of the overlapping guard plate assembly 2 during movement.

[0117] The end of the protrusion is set at a certain angle to the protrusion, and the shape of the wear plate 26 is adapted to the shape of the end to increase the wear area of ​​the wear plate 26 and further ensure the stability of the overlapping guard plate assembly 2 during movement.

[0118] In this embodiment, the pin seat body 24 is T-shaped, with the head of the T-shape being the end of the protruding part, used to install the wear plate 26.

[0119] The wear plate 26 and the overlapping guard plate mounting shaft 241 are located on both sides of the pin seat body 24.

[0120] The overlapping guard plate mounting shaft 241 is perpendicular to the overlapping guard plate 2, that is, the overlapping guard plate mounting shaft 241 is parallel or approximately parallel to the intermediate guard plate mounting shaft 321.

[0121] The overlapping guard plate assembly 2 includes an overlapping guard plate body 21, and an overlapping guard plate mounting shaft 241 is perpendicular to the overlapping guard plate body 21.

[0122] The overlapping protective plate body 21 is a profile.

[0123] The overlapping guard plate body 21 has an overlapping guard plate body slide groove 211, and the pin seat body 24 is fixed to the overlapping guard plate body slide groove 211 by a fixing component.

[0124] The fixing components include screws, washers, and a slider located in the slide groove 211 of the overlapping guard plate body, with the screws and slider threaded together. This method facilitates assembly.

[0125] The overlapping guard plate mounting shaft 241 is assembled with the connecting rod assembly 4. The overlapping guard plate mounting shaft 241 is located between the wear plate 26 on the protruding part and the overlapping guard plate assembly 2.

[0126] A wear plate 26 that slides and engages with the intermediate guard plate assembly 3 is provided on the protruding part of the lap guard plate assembly 2 protruding from the pin seat body 24. A wear-resistant layer 35 that slides and engages with the lap guard plate assembly 2 is provided at the overlapping part of the intermediate guard plate assembly 3 and the lap guard plate assembly 2. The lap guard plate mounting shaft 241, which is assembled with the connecting rod assembly 4, is located between the wear plate 26 and the lap guard plate assembly 2 on the protruding part. Therefore, during the shrinking or stretching of the side guard plate, since there are wear parts on both sides of the lap guard plate mounting shaft 241 that slide and engage with the intermediate guard plate assembly 3, the force acting on the lap guard plate mounting shaft 241 will not cause the lap guard plate assembly 2 to rotate horizontally. This can prevent the lap guard plate assembly 2 from colliding with other components (especially the connecting rod assembly and the intermediate guard plate assembly 3), avoid damage to the side guard plate, and ensure the service life of the side guard plate.

[0127] In addition, this embodiment uses a planar pin body 24 with a pin perpendicular to it for assembly with a linkage mechanism, resulting in a strength greater than... Figure 1 The L-shaped mounting bracket shown has a longer lifespan.

[0128] The axis of the overlapping guard plate mounting shaft 241 does not intersect with the overlapping guard plate body 21. On the one hand, the overlapping guard plate mounting shaft 241 is closer to the wear plate 26, which allows the deflection force generated by the contraction or extension of the connecting rod assembly 4 to be applied to the wear plate 26 as soon as possible, preventing the overlapping guard plate assembly 2 from rotating horizontally as early as possible. On the other hand, the width of the overlapping guard plate assembly does not need to cover the overlapping guard plate mounting shaft 241, which can reduce the width of the overlapping guard plate assembly to a certain extent, thus facilitating the weight reduction of the side guard plate.

[0129] The overlapping part of the overlapping guard plate component 2 and the side guard plate component 1 is provided with an overlapping guard plate wear-resistant layer 25 that slides in cooperation with the side guard plate component 1.

[0130] The end of the overlapping part of the overlapping guard plate body 21 and the side guard plate 1 is bent inward to form the bending surface 212 of the overlapping guard plate body. The inner side of the overlapping guard plate body 21 has an overlapping guard plate wear-resistant layer mounting plate 213, which is connected to the bending surface 212 of the overlapping guard plate body.

[0131] The wear-resistant layer mounting plate 213 of the overlapping protective plate is opposite to the overlapping protective plate body 21, and the wear-resistant layer mounting plate 213 is connected to the inner side of the overlapping protective plate body 21. Generally, the overlapping protective plate body 21, the wear-resistant layer mounting plate 213, and the bending surface 212 of the overlapping protective plate body are integrally formed profiles, and the overlapping protective plate body 21, the wear-resistant layer mounting plate 213, and the bending surface 212 of the overlapping protective plate body form a cavity, which can reduce the weight of the overlapping protective plate assembly 2.

[0132] The overlapping guard plate assembly 2 also includes an upper skirt 22 and a lower skirt 23, which are respectively installed at the upper and lower ends of the overlapping guard plate body 21.

[0133] The lap guard plate body groove 211 passes through the upper and lower ends of the lap guard plate body 21, and the upper skirt 22 and lower skirt 23 of the lap guard plate are fixed to the lap guard plate body groove 211 by fixing components.

[0134] like Figure 3-7 As shown in Figures 15-17, the side guard plate assembly 1 includes a connecting rod assembly seat 18, which is assembled with the connecting rod assembly 4.

[0135] The connecting rod assembly 18, the overlapping guard plate mounting shaft 241, and the intermediate guard plate mounting shaft 321 are arranged in the extension and retraction direction of the connecting rod assembly 4.

[0136] The side guard plate assembly 1 includes a side guard plate body 11, an upper side guard plate skirt 12, a lower side guard plate skirt 13, a bearing seat 14, and a shaft 15.

[0137] The side guard plate body 11 is provided with a side guard plate body slide groove 16, which passes through the upper and lower ends of the side guard plate body 11.

[0138] The connecting rod assembly seat 18 is fixed to the side guard plate body slide groove 16 by a fixing component, the shaft seat 14 is fixed to the side guard plate body slide groove 16 by a fixing component, and the shaft body 15 is mounted on the shaft seat 14.

[0139] The axle 15 is also installed on the side guard plate support assembly 106 of the passageway. The axle 15 is provided with a bushing 17, which is fastened by an end shaft. The bushing 17 is made of wear-resistant and noise-reducing metal. The bushing 17 ensures that after the side guard plate is installed on the passageway, no noise will be generated between the axle 15 and the side guard plate support assembly 106 during vehicle movement, and it will also extend the service life of the axle 15.

[0140] Among them, the connecting rod assembly seat 18 and the shaft seat 14 share at least one side guard plate body slide groove 16.

[0141] The upper skirt 12 and the lower skirt 13 of the side guard plate are fixed to the slide groove 16 of the side guard plate body by a fixing component.

[0142] The fixing components include screws, washers, and a slider located in the slide groove 313 of the intermediate guard plate body, with the screws and slider threaded together. This method facilitates assembly.

[0143] Of course, all fastening components may also include nuts, washers, and T-bolts in the groove.

[0144] During side panel assembly, a sleeve is first installed on the mounting shaft 321 of the intermediate side panel assembly 3, and a sleeve and bushing are installed on the mounting shaft 241 of the overlapping side panel assembly 2. This ensures the fit between the contact surfaces of the side panel assembly 1, overlapping side panel assembly 2, and intermediate side panel assembly 3 after assembly. The connecting rod assembly 4 is mounted on the intermediate side panel mounting shaft 321, the overlapping side panel mounting shaft 241, and the connecting rod assembly mounting seat 18. A compression spring is also installed on the intermediate side panel mounting shaft 321 to ensure that no large gaps occur between the contact surfaces of the side panel assembly 1, overlapping side panel assembly 2, and intermediate side panel assembly 3 during vehicle transportation. The wear-resistant components between the panel assemblies ensure that no noise is generated during the relative movement of the side panel assembly 1, overlapping side panel assembly 2, and intermediate side panel assembly 3, and also prevent damage to their visible surfaces. The connecting rod assembly 4 ensures that the side panel structure can be stretched and compressed horizontally within a certain range, as well as offset relatively vertically. Flexible skirts are installed at the top and bottom ends of the side guards, which increases the ease of installation.
