[0048] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0049] The ladder 100 of a vehicle according to an embodiment of this application is described below with reference to Figures 1-15.

[0050] Referring to Figures 1, 2, and 3, a vehicle ladder 100 according to an embodiment of this application includes: a mounting assembly 1 and a ladder assembly 2. The ladder 100 is generally adapted to be mounted to the body 7 of a vehicle 200 via the mounting assembly 1. The ladder assembly 2 includes a first part 21 and a second part 22. The ladder assembly 2 is disposed on the mounting assembly 1 and has a retracted state and an extended state. In the retracted state, both the first part 21 and the second part 22 are retracted into the mounting assembly 1. In the extended state, at least a portion of the second part 22 and / or at least a portion of the first part 21 extends out relative to the mounting assembly 1.

[0051] The ladder 100 of this application embodiment is suitable for installation on the body 7 of the vehicle 200 via the mounting assembly 1. When a user needs to use the ladder 100 to climb to the roof of the vehicle, the ladder assembly 2 can be switched to the extended state, and the first part 21 and / or the second part 22 extend out from the mounting assembly 1 for the user's use. When the user does not need to use the ladder 100, the ladder assembly 2 can be switched to the retracted state, that is, the first part 21 and the second part 22 are both retracted into the mounting assembly 1, which reduces the space occupied by the ladder 100 as a whole and improves the convenience of using the ladder 100.

[0052] To ensure the stability of the first part 21 and the second part 22 in the stored state, referring to Figures 3, 4 and 5, the ladder 100 further includes a first limiting component 3 and a second limiting component 4. In the stored state, the first part 21 is positioned on the mounting component 1 by the first limiting component 3, and the second part 22 is positioned on the mounting component 1 by the second limiting component 4.

[0053] According to the embodiments of this application, the vehicle ladder 100 limits the first part 21 and the second part 22 by the first limiting component 3 and the second limiting component 4 respectively, ensuring the stability of the overall structure of the ladder 100 and effectively reducing the possibility of abnormal noise from the ladder 100 when the vehicle 200 is in motion.

[0054] In some embodiments, the first portion 21 is rotatably disposed on the mounting assembly 1, and the second portion 22 is rotatable at least relative to the first portion 21.

[0055] In the stowed state, the first part 21 rotates to be stored in the mounting component 1, and the second part 22 rotates to be stacked with the first part 21. That is to say, the first part 21 and the second part 22 in the ladder component 2 are folded and accommodated in the mounting component 1, which further reduces the overall space occupied by the ladder 100 in the stowed state.

[0056] In the extended state, the first part 21 rotates away from the mounting component 1, meaning the entire ladder assembly 2 moves away from the vehicle body 7, thus creating a certain distance between the ladder assembly 2 and the vehicle body 7 to prevent the user from colliding with the vehicle body 7 when using the ladder assembly 2. The second part 22 can rotate to its end to splice with the end of the first part 21 to form a ladder that is easy for the user to use.

[0057] It should be noted that the "rotatable" mentioned in the above technical solution refers to the rotation mode of the first part 21 and the second part 22, but the first part 21 and the second part 22 may also not rotate. For example, when the ladder assembly 2 switches between the retracted state and the extended state, the first part 21 and the second part 22 rotate. However, when the ladder assembly 2 is in the retracted state or the extended state, the first part 21 and the second part 22 do not rotate, ensuring the stability of the ladder assembly 2 in both the retracted and extended states.

[0058] Referring to Figures 3, 4, and 6, in some embodiments, the first limiting component 3 includes a first limiting rod 31 and a first limiting slot 32. One of the first limiting rod 31 and the first limiting slot 32 is disposed on the mounting component 1 and the other is disposed on the first part 21. In the storage state, the first limiting rod 31 is engaged in the first limiting slot to restrict the rotation of the first part 21 relative to the mounting component 1, thereby positioning the first part 21 on the mounting component 1 and ensuring the stability of the first part 21 in the storage state.

[0059] The first limiting rod 31 can be disposed on the first part 21, and the first limiting slot 32 can be disposed on the mounting component 1; alternatively, the first limiting rod 31 can be disposed on the mounting component 1, and the first limiting slot 32 can be disposed on the first part 21. The key is that when the first limiting rod 31 is engaged with the first limiting slot 32, it can restrict the rotation of the first part 21 relative to the mounting component 1. In some specific embodiments, the first limiting slot 32 is disposed on the mounting component 1 with its opening facing upwards, and the first limiting rod 31 is disposed on the first part 21.

[0060] Referring to Figures 1, 2 and 3, in some embodiments, the first part 21 is rotatably connected to the mounting assembly 1 via a linkage assembly 5. In the retracted state, the first part 21 moves to be retracted into the mounting assembly 1, and in the extended state, the first part 21 moves to extend out of the mounting assembly 1. The linkage assembly 5 ensures the stability of the first part 21 when rotating.

[0061] Referring to Figures 2, 3, and 4, specifically, the linkage assembly 5 includes: a first linkage 51 and a second linkage 52. The two ends of the first linkage 51 are rotatably connected to the mounting assembly 1 and the first part 21, respectively. The two ends of the second linkage 52 are rotatably connected to the mounting assembly 1 and the first part 21, respectively. The first linkage 51 and the second linkage 52 are spaced apart in the vertical direction. The first part 21, the mounting assembly 1, the first linkage 51, and the second linkage 52 form a four-bar linkage mechanism. The length of the first linkage 51 is equal to the length of the second linkage 52, so that the first part 21 can always remain parallel to the mounting assembly 1 when rotating, which is convenient for user operation.

[0062] It should be noted that the linkage assembly 5 can be set in multiple groups to further ensure the stability of the first part 21. For example, in some specific embodiments, the linkage assembly 5 is set in two groups, and the two groups of linkage assemblies 5 are distributed on the left and right sides of the first part 21.

[0063] In some further embodiments, the first limiting rod 31 is movably disposed on the connecting rod assembly 5, and the first part 21 is rotatably connected to the connecting rod assembly 5 through the first limiting rod 31.

[0064] In the above technical solution, the first part 21 can rotate relative to the connecting rod assembly 5 via the first limiting rod 31. At the same time, because the first limiting rod 31 is movably disposed on the connecting rod assembly 5, the first part 21 can also move relative to the connecting rod assembly 5. When the first part 21 rotates to be housed in the mounting assembly 1, moving the first part 21 causes the first limiting rod 31 to move into the first limiting slot 32, thereby restricting the rotation of the first part 21 and ensuring the stability of the first part 21.

[0065] It should be noted that the "movable" mentioned in the above technical solution refers to the first limiting rod 31 having this movement mode; the first limiting rod 31 may also remain stationary. For example, when the ladder assembly 2 switches between the retracted state and the extended state, the first limiting rod 31 moves. However, when the ladder assembly 2 is in the retracted state, the first limiting rod 31 does not move, ensuring the stability of the ladder assembly 2 when it is in the retracted state.

[0066] Referring to Figures 3, 4, and 6, in some specific embodiments, one end of the first connecting rod 51 is rotatably connected to the mounting assembly 1 via a first rotating pin 511, and the other end of the first connecting rod 51 is rotatably connected to the first part 21 via a second rotating pin 512. The first connecting rod 51 is provided with an elongated hole 53 for the second rotating pin 512 to move. Referring to Figure 14, one end of the second connecting rod 52 is rotatably connected to the mounting assembly 1 via a third rotating pin 521, and the other end of the second connecting rod 52 is rotatably connected to the first part 21 via a fourth rotating pin 522. The second connecting rod 52 is provided with an elongated hole 53 for the fourth rotating pin 522 to move. Both the second rotating pin 512 and the fourth rotating pin 522 are disposed in the first part 21, thereby allowing the first part 21 to rotate relative to the connecting rod assembly 5 while also moving relative to the connecting rod assembly 5.

[0067] The mounting component 1 is provided with a hook 11, which defines a first limiting slot 32, with the opening of the first limiting slot 32 facing upward.

[0068] When the first part 21 needs to be stored, the first part 21 is first rotated by the first connecting rod 51 and the second connecting rod 52 until the second rotating pin 512 interferes with the hook 11. Then the first part 21 is pushed upward, and the second rotating pin 512 and the fourth rotating pin 522 move in the corresponding elongated holes 53 respectively, and move until the second rotating pin 512 passes the part that interferes with the hook 11. Then the first connecting rod 51 and the second connecting rod 52 rotate until the second rotating pin 512 is directly above the first limiting slot 32. Then the first part 21 is released, and the second rotating pin 512 moves in the elongated hole 53 and moves to be locked in the first limiting slot 32. That is to say, in this embodiment, the second rotating pin 512 is the first limiting rod 31.

[0069] When the first part 21 needs to be extended, the first part 21 must be moved upward as a whole to drive the second rotating pin 512 to disengage from the first limiting slot 32, so that the first connecting rod 51 and the second connecting rod 52 can rotate until the first part 21 extends out of the mounting assembly 1, effectively ensuring the stability of the first part 21 in the stored state.

[0070] It should be noted that in this embodiment, the second rotating pin 512 is formed as the first limiting rod 31. In other embodiments, the fourth rotating pin 522 may be formed as the first limiting rod 31, or multiple first limiting slots 32 may be provided, with both the second rotating pin 512 and the fourth rotating pin 522 forming the first limiting rod 31. Alternatively, the first limiting rod 31 may be constructed as a structure independent of the second rotating pin 512 and the fourth rotating pin 522. This application does not impose any restrictions on this.

[0071] In some embodiments, the ladder 100 further includes a tension spring 513, the two ends of which are connected to the connecting rod assembly 5 and the first limiting rod 31 respectively to restrict the first limiting rod 31 from disengaging from the first limiting slot 32, further ensuring the stability of the first part 21 in the retracted state. Furthermore, during the process of switching to the extended state, the ladder assembly 2 can also rely on the dynamic balance of gravity and the tension of the tension spring 513 to obtain constant damping, thereby facilitating user operation.

[0072] Referring to Figure 2, in some embodiments, the mounting component 1 is further provided with a plurality of second limiting slots 12. When the first part 21 is rotated to be housed in the mounting component 1, at least a portion of the first connecting rod 51 is located in the corresponding second limiting slot 12 to restrict the movement of the first connecting rod 51 in the left and right directions, and at least a portion of the second connecting rod 52 is located in the corresponding second limiting slot 12 to restrict the movement of the second connecting rod 52 in the left and right directions, thereby further ensuring the stability of the first part 21 in the housed state.

[0073] In other embodiments, the mounting component 1 may be provided with multiple protrusions. When the first part 21 is rotated to be housed in the mounting component 1, the multiple protrusions abut against the left and right sides of the first connecting rod 51 and the left and right sides of the second connecting rod 52, respectively, so as to restrict the movement of the first connecting rod 51 and the second connecting rod 52 in the left and right directions, and further ensure the stability of the first part 21 in the housed state.

[0074] Referring to Figures 2, 3 and 4, in some embodiments, the first part 21 is provided with a plurality of horizontal bars 23 for users to climb, and the plurality of horizontal bars 23 are spaced apart in the vertical direction. The second part 22 is also provided with a plurality of horizontal bars 23, and the plurality of horizontal bars 23 are spaced apart in the vertical direction. The mounting assembly 1 is provided with at least one horizontal bar 23 to facilitate user climbing.

[0075] The mounting assembly 1 has a third limiting slot 18 for fixing the crossbar 23. The opening of the third limiting slot 18 faces the same direction as the opening of the first limiting slot 32. In the folded state, one of the crossbars 23 on the first part 21 is engaged in the third limiting slot 18, which restricts the rotation of the first part 21 and further ensures the stability of the first part 21 in the folded state.

[0076] When the first part 21 needs to be extended, the first part 21 must be moved upward as a whole, causing the second rotating pin 512 to disengage from the first limiting slot 32. At the same time, the crossbar 23 on the first part 21 disengages from the third limiting slot 18, so that the first connecting rod 51 and the second connecting rod 52 can rotate until the first part 21 extends out of the mounting assembly 1, effectively ensuring the stability of the first part 21 in the stored state.

[0077] Referring to Figures 2, 5, and 6, in some embodiments, the second limiting component 4 includes a locking mechanism 41 disposed on the mounting component 1 and a locking member 42 disposed on the second part 22. In the retracted state, the locking member 42 engages with the locking mechanism 41 to restrict the movement of the second part 22. The locking mechanism 41 may be configured to disengage from the locking member 42 so that the second part 22 can move relative to the first part 21 to switch to an extended state.

[0078] Through the above technical solution, the second part 22 can be locked and positioned on the mounting component 1 by the locking member 42 and the locking mechanism 41, thereby ensuring the stability of the second part 22 in the storage state.

[0079] Referring to Figures 2, 5, and 6, in some embodiments, the first end of the second part 22 is rotatably connected to the lower end of the first part 21 via a flip hinge 221. The locking mechanism 41 includes a locking part 411 and an unlocking part 412. The locking part 411 is movably disposed on the mounting assembly 1 to switch between a locked position and an unlocked position. In the locked position, the locking part 411 engages with the locking member 42, and in the unlocked position, the locking part 411 disengages from the locking member 42.

[0080] The unlocking part 412 is located below the locking part 411. The unlocking part 412 is connected to the locking part 411 to at least control the locking part 411 from disengaging from the locking member 42.

[0081] The above technical solution reduces the height of the unlocking part 412, making it easier for users to unlock. When the user needs to use the ladder 100, the unlocking part 412 can control the locking part 411 to disengage from the locking member 42, thereby releasing the restriction on the second part 22 and allowing the second part 22 to rotate to extend out of the mounting assembly 1.

[0082] In some specific embodiments, the locking part 411 includes a rotatable movable locking tongue 4111 and a locking tongue spring. The movable locking tongue 4111 is rotatably disposed on the mounting assembly 1. A locking member 42 is provided at the second end of the second part 22. The locking member 42 is constructed as a first locking ring 421. When the second part 22 is rotated to be housed in the mounting assembly 1, the movable locking tongue 4111 rotates to at least partially insert into the first locking ring 421 to restrict the movement of the first locking ring 421, thereby positioning the second part 22 on the mounting assembly 1.

[0083] The locking tongue spring is connected to the movable locking tongue 4111 and the mounting assembly 1 respectively. The locking tongue spring applies a force to the movable locking tongue 4111 to rotate toward the locked position, ensuring that the movable locking tongue 4111 can be stably inserted into the first locking ring 421.

[0084] Referring to Figures 6, 8, and 14, specifically, the unlocking part 412 includes an opening handle 4121 rotatably disposed on the mounting assembly 1. The opening handle 4121 is connected to the movable locking tongue 4111 via a pull member 4122. By pulling the opening handle 4121, the pull member 4122 can be moved, and the pull member 4122 causes the movable locking tongue 4111 to rotate until it disengages from the first locking ring 421, thereby releasing the restriction on the second part 22. The second part 22 can then rotate to extend out of the first part 21.

[0085] In some embodiments, the mounting component 1 is further provided with a lock body structure 13, which is configured to lock the position of the pull member 4122 or unlock the pull member 4122.

[0086] The lock body structure 13 is adapted to lock the pull member 4122, restrict the movement of the pull member 4122, and avoid the risk of other personnel accidentally touching the opening handle 4121, causing the second part 22 to extend out of the mounting component 1.

[0087] In some specific embodiments, the lock body structure 13 includes a lock cylinder structure 131 and a lock cylinder lever 133 linked to the lock cylinder structure 131. The lock cylinder structure 131 is rotatably disposed on the mounting assembly 1 and connected to the lock cylinder lever 133 to drive the lock cylinder lever 133 to rotate. The lock cylinder lever 133 is adapted to contact the pulling member 4122 to lock the pulling member 4122 or to separate from the pulling member 4122. The specific way in which the lock cylinder lever 133 locks the pulling member 4122 can be that a part of the lock cylinder lever 133 is engaged with the pulling member 4122, or the lock cylinder lever 133 abuts against the pulling member 4122, limiting the movement of the pulling member 4122 by friction, or other limiting methods. This application does not limit this.

[0088] The lock cylinder structure 131 has a matching key 132. When the ladder 100 needs to be opened, the key 132 is first inserted into the lock cylinder structure 131, and the key 132 is turned so that the lock cylinder plate moves away from the pull member 4122 under the action of the lock cylinder torsion spring of the lock cylinder structure 131, thereby releasing the restriction on the pull member 4122. Without releasing the key 132, the opening handle 4121 is pulled. The opening handle 4121 causes the pull member 4122 to have a travel displacement. The pull member 4122 causes the movable lock tongue 4111 to rotate until it disengages from the first lock ring 421, thereby releasing the restriction on the second part 22. The second part 22 can then rotate to extend out of the first part 21.

[0089] Referring to Figures 2, 5, and 6, in some embodiments, the second limiting component 4 further includes an elastic clamping member 43 and a mating member 44. One of the elastic clamping member 43 and the mating member 44 is disposed on the mounting component 1 and the other is disposed on the second part 22. In the retracted state, the elastic clamping member 43 clamps the mating member 44 to buffer the vibration of the second part 22, further reducing the possibility of abnormal noise caused by the vibration of the second part 22.

[0090] The elastic clamping member 43 can be set on the mounting component 1 and the mating member 44 can be set on the second part 22, or the elastic clamping member 43 can be set on the second part 22 and the mating member 44 can be set on the mounting component 1. As long as the elastic clamping member 43 clamps the mating member 44, it can buffer the vibration of the second part 22.

[0091] In some embodiments, the elastic clamping member 43 includes at least an elastic clamping groove, and the mating member 44 is a mating protrusion protruding from the second part 22. In the retracted state, the mating protrusion abuts against the inner wall of the clamping groove. The connection between the elastic clamp and the mating member 44 can be achieved by rotating the second part 22 until the mating protrusion inserts into the clamping groove, which reduces the difficulty of operation. Furthermore, the abutment between the inner wall of the clamping groove and the mating protrusion can buffer the rotation of the second part 22 from multiple angles, further reducing the risk of abnormal noise from the second part 22.

[0092] In some specific embodiments, the mating member 44 is configured as a second locking ring 441 disposed at the second end of the second part 22, the first locking ring 421 and the second locking ring 441 are distributed on the left and right sides of the second part 22, and the elastic clamping member 43 defines a clamping groove adapted to the second locking ring 441. When the second part 22 rotates to the point where the first locking ring 421 engages with the locking structure, the second locking ring 441 is inserted into the clamping groove of the elastic clamping member 43.

[0093] The above technical solution features a simple structure for the elastic clamping component 43 and the mating component 44, which reduces the cost of the climbing ladder 100.

[0094] Referring to Figures 9, 10 and 11, in some embodiments, the extended state includes a first state in which a first portion 21 is housed in the mounting assembly 1 and a second portion 22 is rotated to extend out of the first portion 21 and the mounting assembly 1.

[0095] When the user needs to use the ladder 100, first release the second limiting component 4 from the second part 22, so that the second part 22 can rotate to extend out of the first part 21 and the mounting component 1. At this time, the ladder 100 is in the first state. Then release the first limiting component 3 from the first part 21, so that the first part 21 can rotate to extend out of the mounting component 1, thereby making the ladder 100 fully switch to the extended state.

[0096] In some embodiments, the mounting assembly 1 is provided with an elastic stop member 14. In a first state, the elastic stop member 14 stops the second part 22 to limit the rotation range of the second part 22. The second part 22 is configured to be driven by the first part 21 to separate from the elastic stop member 14 and can be switched to an extended state.

[0097] Through the above technical solution, in the first state, the elastic stop member 14 stops the second part 22, restricting the continued rotation of the second part 22 and preventing the second part 22 from colliding with the vehicle body 7. When the first part 21 rotates to extend out of the mounting component 1, the first part 21 drives the second part 22 to move away from the mounting component 1, thereby separating the second part 22 from the elastic stop member 14, releasing the restriction on the second part 22, and the second part 22 can continue to rotate to splice with the end of the first part 21.

[0098] In some specific embodiments, the elastic stop 14 is disposed at the bottom end of the mounting assembly 1. The elastic stop 14 is configured such that when the second part 22 rotates to 155° in the first state, it stops against the elastic stop 14 to prevent the paint from being damaged when the second part 22 is flipped over.

[0099] Referring to Figures 3, 4 and 14, in some embodiments, the linkage assembly 5 is provided with a first stop member 54, and the mounting assembly 1 is provided with a second stop member 15. In the extended state, the first stop member 54 and the second stop member 15 abut against each other to limit the rotation range of the linkage assembly 5.

[0100] In the extended state, the first stop member 54 and the second stop member 15 stop and restrict the downward rotation of the linkage assembly 5, ensuring the stability of the first part 21 in the extended state and ensuring the reliability of the user when using the ladder 100.

[0101] In some embodiments, the first stop member 54 includes a first stop pin 541 passing through the link assembly 5, and the second stop member 15 includes a mounting seat 151 for mounting a rotating pin. The link assembly 5 is rotatably connected to the mounting assembly 1 via the rotating pin, and the first stop pin 541 contacts the mounting seat 151 to limit the rotation range of the link assembly 5.

[0102] In the above technical solution, the mounting base 151 is directly formed as the second stop member 15, without the need for other structures, which is conducive to the simplification of the ladder 100 structure. Furthermore, the first stop pin 541 is inserted through the connecting rod assembly 5, ensuring the stability of the connection between the first stop pin 541 and the connecting rod assembly 5. In the extended state, the first stop pin 541 can be stably supported on the mounting base 151, ensuring the reliability of the ladder 100 when the user uses it.

[0103] In some specific embodiments, the first connecting rod 51 is rotatably connected to the mounting assembly 1 via a first rotating pin 511, and the second connecting rod 52 is rotatably connected to the mounting assembly 1 via a third rotating pin 521. Both the first connecting rod 51 and the second connecting rod 52 are provided with a first stop pin 541, and the mounting seats 151 of both the first rotating pin 511 and the third rotating pin 521 are formed as second stop members 15.

[0104] In the extended state, the first stop pin 541 on the first link 51 and the mounting seat 151 of the first rotating pin 511 stop and restrict the rotation of the first link 51. The first stop pin 541 on the second link 52 and the mounting seat 151 of the third rotating pin 521 stop and restrict the rotation of the second link 52, thereby restricting the rotation of the link assembly 5 and ensuring the stability of the first part in the extended state.

[0105] When in the stowed state, the linkage assembly 5 and the mounting assembly 1 abut against each other, thereby limiting the rotation of the linkage assembly 5 and ensuring the stability of the first part in the stowed state.

[0106] In the above technical solution, the first stop member 54 and the second stop member 15 have simple structures, which reduces the cost of the ladder 100.

[0107] In some specific embodiments, one end of the tension spring 513 is connected to the first stop pin 541 and the other end is connected to the second rotating pin 512 (first limiting rod 31), which reduces the installation difficulty of the tension spring 513.

[0108] Referring to Figures 7, 8 and 9, in some embodiments, the mounting assembly 1 further includes a mounting portion 16 for engaging with the body 7 of the vehicle 200 to secure the mounting assembly 1 to the body 7.

[0109] Referring to Figures 11, 12, and 13, in some specific embodiments, the mounting part 16 includes an upper mounting member 161 and a lower mounting member 162. The upper mounting member 161 is disposed on the top of the mounting assembly 1 and has multiple mounting holes. The upper mounting member 161 is adapted to be mounted on the top of the vehicle body 7 by multiple fasteners. The lower mounting member 162 is disposed at the bottom of the mounting assembly 1 and is located on the side of the mounting assembly 1 facing the vehicle body 7. The lower mounting member 162 has multiple mounting holes and is adapted to be mounted on the side of the vehicle body 7 by multiple fasteners, effectively ensuring the firmness of the connection between the mounting assembly 1 and the vehicle body 7.

[0110] In some embodiments, the ladder 100 further includes a shielding component, which is detachably connected to the mounting component 1 and shields the mounting portion 16 of the mounting component 1, preventing the mounting portion 16 from being exposed, ensuring the aesthetics of the vehicle 200, and also shielding the mounting portion 16 from rainwater, reducing the risk of water entering the vehicle body 7. When it is necessary to remove the ladder 100 from the vehicle body 7, the shielding component is first removed to expose the mounting portion 16, so that the user can perform the removal operation of the mounting portion 16.

[0111] In some embodiments, the shielding component includes an upper decorative cover, which is detachably connected to the upper mounting member 161 via a snap fastener and a mushroom-shaped fastener, and covers the upper mounting member 161 to prevent the upper mounting member 161 from being exposed.

[0112] Referring to Figures 1 and 13, in some embodiments, the mounting component 1 is further provided with a clearance hole 17 to facilitate the installation of the lower mounting component 162 by the operator. The shielding component also includes a sealing cover, which, when the operator completes the installation of the lower mounting component 162, closes the clearance hole 17 by a removable sealing cover to shield the lower mounting component 162.

[0113] Referring to Figures 11 and 13, in some embodiments, the ladder 100 further includes a water-blocking member 6, which is disposed on the upper side of the mounting portion 16 of the mounting assembly 1. The water-blocking member 6 is adapted to abut against the vehicle body 7 to restrict water flow to the mounting portion 16, thereby further reducing the risk of water entering the vehicle body 7.

[0114] In some specific embodiments, the water-blocking component 6 is constructed as a bubble tube sealing strip. The water-blocking component 6 is disposed on the upper side of the lower mounting component 162, and is adapted to be interference-fitted with the vehicle body 7 to achieve a sealed water-blocking effect. When it rains, water flows through the water-blocking component 6 to both sides, reducing the risk of water entering the vehicle body 7.

[0115] Referring to FIG15, the vehicle 200 according to an embodiment of the present application includes: a body 7 and a ladder 100 in the above technical solution, and the mounting component 1 is positioned on the body 7.

[0116] According to the vehicle 200 of this application embodiment, the first part 21 and the second part 22 are limited by the first limiting component 3 and the second limiting component 4 respectively, which ensures the stability of the overall structure of the ladder 100 and effectively reduces the possibility of abnormal noise from the ladder 100 when the vehicle 200 is in motion.

[0117] In some embodiments, the vehicle body 7 is provided with a plurality of openings for mounting the ladder 100. The vehicle 200 also includes a trim assembly, which can cover the openings on the vehicle body 7 when the vehicle 200 does not need to be equipped with the ladder 100. This allows a single vehicle body 7 to meet different vehicle 200 configurations, greatly reducing the development cost of the parts.

[0118] Specifically, the trim assembly includes a trim strip and a clip integrated on the trim strip. The clip corresponds to an opening on the body 7, and the trim assembly can block the opening on the body 7 through the clip.

[0119] The buckle is made of plastic, which allows it to be disassembled multiple times without deforming, and the trim component can be installed and removed multiple times.

[0120] In some embodiments, the opening on the vehicle body 7 for installing the lower mounting member 162 is a blind hole. The lower mounting member 162 is fixed to the vehicle body 7 by means of a rivet nut. After the vehicle body 7 is riveted, it protrudes at least 1.5mm, thereby further preventing water from seeping into the vehicle and preventing water dripping, seepage, and leakage problems in the vehicle 200 during the use of the ladder 100.
