[0048] Reference below Figure 1-Figure 15 A vehicle climbing ladder 100 according to an embodiment of the present invention will be described.

[0049] Reference Figure 1 , Figure 2 and Figure 3 A vehicle ladder 100 according to an embodiment of the present invention comprises: a mounting assembly 1 and a ladder assembly 2. The ladder 100 as a whole is suitable for being mounted on a vehicle body 7 of a vehicle 200 through the mounting assembly 1. The ladder assembly 2 comprises a first portion 21 and a second portion 22. The ladder assembly 2 is disposed on the mounting assembly 1 and has a stowed state and an extended state. In the stowed state, both the first portion 21 and the second portion 22 are stowed in the mounting assembly 1. In the extended state, at least a portion of the second portion 22 and / or at least a portion of the first portion 21 extends relative to the mounting assembly 1.

[0050] The ladder 100 of the embodiment of the present invention is suitable for being installed on the body 7 of the vehicle 200 through the mounting assembly 1. When the user needs to use the ladder 100 to climb to the roof, the ladder assembly 2 can be switched to the extended state, and the first part 21 and / or the second part 22 are extended from the mounting assembly 1 for user use; when the user does not need to use the ladder 100, the ladder assembly 2 can be switched to the storage state, that is, the first part 21 and the second part 22 are both stored in the mounting assembly 1, thereby reducing the space occupied by the ladder 100 as a whole and improving the convenience of using the ladder 100.

[0051] In order to ensure the stability of the first part 21 and the second part 22 in the storage state, refer to Figure 3 , Figure 4 and Figure 5 The ladder 100 further includes: a first limiting assembly 3 and a second limiting assembly 4. In the storage state, the first part 21 is positioned on the installation assembly 1 through the first limiting assembly 3, and the second part 22 is positioned on the installation assembly 1 through the second limiting assembly 4.

[0052] According to the vehicle ladder 100 of the embodiment of the present invention, the first part 21 and the second part 22 are limited by the first limiting assembly 3 and the second limiting assembly 4 respectively, thereby ensuring the stability of the overall structure of the ladder 100 and effectively reducing the possibility of abnormal noise generated by the ladder 100 when the vehicle 200 is driving.

[0053] In some embodiments, the first portion 21 is rotatably disposed on the mounting assembly 1 , and the second portion 22 is at least rotatable relative to the first portion 21 .

[0054] In the storage state, the first part 21 rotates to be stored in the installation component 1, and the second part 22 rotates to overlap with the first part 21. That is, the first part 21 and the second part 22 in the ladder component 2 are folded and accommodated in the installation component 1, further reducing the space occupied by the entire ladder 100 in the storage state.

[0055] In the extended state, the first part 21 rotates away from the mounting assembly 1, that is, the ladder assembly 2 as a whole moves in a direction away from the vehicle body 7, so that there is a certain distance between the ladder assembly 2 and the vehicle body 7, so as to prevent the user from colliding with the vehicle body 7 when using the ladder assembly 2. The second part 22 can be rotated to the end and spliced ​​with the end of the first part 21 to form a ladder that is convenient for the user to use.

[0056] It should be noted that the "rotatable" mentioned in the above technical solution means that the first part 21 and the second part 22 have such a rotation mode, and the first part 21 and the second part 22 may not rotate. For example, when the ladder assembly 2 switches between the storage state and the extended state, the first part 21 and the second part 22 rotate, but when the ladder assembly 2 is in the storage state or in the extended state, the first part 21 and the second part 22 do not rotate, thereby ensuring the stability of the ladder assembly 2 in the storage state and in the extended state.

[0057] Reference Figure 3 , Figure 4 and Figure 6 In some embodiments, the first limiting assembly 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 set on the installation assembly 1 and the other is set on the first part 21, and in the storage state, the first limiting rod 31 is clamped in the first limiting slot to limit the rotation of the first part 21 relative to the installation assembly 1, thereby positioning the first part 21 on the installation assembly 1, ensuring the stability of the first part 21 in the storage state.

[0058] The first limiting rod 31 may be disposed on the first portion 21, and the first limiting slot 32 may be disposed on the mounting assembly 1, or the first limiting rod 31 may be disposed on the mounting assembly 1, and the first limiting slot 32 may be disposed on the first portion 21, as long as the first limiting rod 31 can limit the rotation of the first portion 21 relative to the mounting assembly 1 when it is engaged with the first limiting slot 32. In some specific embodiments, the first limiting slot 32 is disposed on the mounting assembly 1 with its opening facing upward, and the first limiting rod 31 is disposed on the first portion 21.

[0059] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the first part 21 is rotatably connected to the mounting assembly 1 via a connecting rod assembly 5. In the stored state, the first part 21 moves to be stored in the mounting assembly 1, and in the extended state, the first part 21 moves to be extended from the mounting assembly 1. The stability of the first part 21 during rotation is ensured by the connecting rod assembly 5.

[0060] Reference Figure 2 , Figure 3 and Figure 4Specifically, the connecting rod assembly 5 includes: a first connecting rod 51 and a second connecting rod 52, the two ends of the first connecting rod 51 are rotatably connected to the mounting assembly 1 and the first part 21 respectively, the two ends of the second connecting rod 52 are rotatably connected to the mounting assembly 1 and the first part 21 respectively, and the first connecting rod 51 and the second connecting rod 52 are spaced apart in the up and down directions. The first part 21, the mounting assembly 1, the first connecting rod 51 and the second connecting rod 52 form a four-bar linkage mechanism, and the length of the first connecting rod 51 is equal to the length of the second connecting rod 52, so that the first part 21 can always remain parallel to the mounting assembly 1 when rotating, which is convenient for user operation.

[0061] It should be noted that the connecting rod assembly 5 can be provided in multiple groups to further ensure the stability of the first part 21 . For example, in some specific embodiments, the connecting rod assembly 5 is provided in two groups, and the two groups of connecting rod assemblies 5 are distributed on the left and right sides of the first part 21 .

[0062] In some further embodiments, the first limiting rod 31 is movably disposed on the connecting rod assembly 5 , and the first portion 21 is rotatably connected to the connecting rod assembly 5 via the first limiting rod 31 .

[0063] In the above technical solution, the first part 21 can be rotated relative to the connecting rod assembly 5 through the first limiting rod 31. At the same time, because the first limiting rod 31 is movably arranged on the connecting rod assembly 5, the first part 21 can also be moved relative to the connecting rod assembly 5. When the first part 21 is rotated to be stored in the installation assembly 1, the first part 21 is moved so that the first limiting rod 31 moves into the first limiting slot 32, thereby limiting the rotation of the first part 21 and ensuring the stability of the first part 21.

[0064] It should be noted that the "movable" mentioned in the above technical solution means that the first limit rod 31 has this movement mode, and the first limit rod 31 may not move. For example, when the ladder assembly 2 switches between the storage state and the extended state, the first limit rod 31 moves, but when the ladder assembly 2 is in the storage state, the first limit rod 31 does not move, thereby ensuring the stability of the ladder assembly 2 in the storage state.

[0065] Reference Figure 3 , Figure 4 and Figure 6 In some specific embodiments, one end of the first connecting rod 51 is rotatably connected to the mounting assembly 1 through a first rotating pin 511, and the other end of the first connecting rod 51 is rotatably connected to the first portion 21 through a second rotating pin 512. The first connecting rod 51 is provided with a long hole 53 for the second rotating pin 512 to move. Fig.14One end of the second connecting rod 52 is rotatably connected to the mounting assembly 1 through the third rotating pin 521, and the other end of the second connecting rod 52 is rotatably connected to the first part 21 through the fourth rotating pin 522. The second connecting rod 52 is provided with a long hole 53 for the fourth rotating pin 522 to move. The second rotating pin 512 and the fourth rotating pin 522 are both provided on the first part 21, so that the first part 21 can rotate relative to the connecting rod assembly 5 and can also move relative to the connecting rod assembly 5.

[0066] The mounting assembly 1 is provided with a hook 11 , which defines a first position-limiting slot 32 , and the opening of the first position-limiting slot 32 is arranged upward.

[0067] When the first part 21 needs to be stored, the first part 21 is first driven by the first connecting rod 51 and the second connecting rod 52 to rotate until the second rotating pin 512 interferes with the hook 11, and then the first part 21 is pushed upward, and the second rotating pin 512 and the fourth rotating pin 522 move in the corresponding long hole 53 respectively, and move until the second rotating pin 512 passes over the part that interferes with the hook 11, and then the first connecting rod 51 and the second connecting rod 52 rotate until the second rotating pin 512 is located directly above the first limiting slot 32, and then the first part 21 is released, and the second rotating pin 512 moves in the long hole 53 and moves to be clamped in the first limiting slot 32, that is, in this embodiment of the application, the second rotating pin 512 is the first limiting rod 31.

[0068] 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 be rotated until the first part 21 extends out of the installation assembly 1, effectively ensuring the stability of the first part 21 in the storage state.

[0069] It should be noted that in the embodiment of the present application, the second rotating pin 512 is formed as the first limiting rod 31. In other embodiments, the fourth rotating pin 522 can also be formed as the first limiting rod 31, or a plurality of first limiting slots 32 are provided, and the second rotating pin 512 and the fourth rotating pin 522 are both formed as the first limiting rod 31, or the first limiting rod 31 is constructed as a structure independent of the second rotating pin 512 and the fourth rotating pin 522. The present application does not impose any restrictions on this.

[0070] In some embodiments, the ladder 100 further includes: a tension spring 513, the two ends of which are respectively connected to the connecting rod assembly 5 and the first limiting rod 31 to limit the first limiting rod 31 from being separated from the first limiting slot 32, further ensuring the stability of the first part 21 in the storage state. In addition, when the ladder assembly 2 is switched to the extended state, it 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.

[0071] Reference Figure 2 In some embodiments, a plurality of second limit slots 12 are further provided on the mounting assembly 1. When the first part 21 is rotated to be stored in the mounting assembly 1, at least a portion of the first connecting rod 51 is located in the corresponding second limit slot 12 to limit 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 limit slot 12 to limit 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 stored state.

[0072] In other embodiments, a plurality of protrusions may be provided on the mounting assembly 1. When the first part 21 is rotated to be stored in the mounting assembly 1, the plurality of protrusions respectively 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 to limit the movement of the first connecting rod 51 and the second connecting rod 52 in the left and right directions, thereby further ensuring the stability of the first part 21 in the stored state.

[0073] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the first part 21 is provided with a plurality of cross bars 23 for users to climb, and the plurality of cross bars 23 are spaced apart in the up-down direction. The second part 22 is also provided with a plurality of cross bars 23, and the plurality of cross bars 23 are spaced apart in the up-down direction. At least one cross bar 23 is provided on the mounting assembly 1 to facilitate users to climb.

[0074] The structure for fixing the cross bar 23 on the mounting assembly 1 defines a third limit slot 18, and the opening direction of the third limit slot 18 is the same as the opening direction of the first limit slot 32. In the storage state, a cross bar 23 on the first part 21 is clamped in the third limit slot 18, which limits the rotation of the first part 21 and further ensures the stability of the first part 21 in the storage state.

[0075] When the first part 21 needs to be extended, the first part 21 must be moved upward as a whole first, driving the second rotating pin 512 to disengage from the first limiting slot 32, and at the same time, the cross bar 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 be rotated until the first part 21 extends out of the installation assembly 1, effectively ensuring the stability of the first part 21 in the storage state.

[0076] Reference Figure 2 , Figure 5 and Figure 6In some embodiments, the second limiting assembly 4 includes a locking mechanism 41 provided on the mounting assembly 1 and a locking member 42 provided on the second portion 22. In the retracted state, the locking member 42 is locked with the locking mechanism 41 to limit the movement of the second portion 22. The locking mechanism 41 can be configured to be disengaged from the locking member 42 so that the second portion 22 can move relative to the first portion 21 to switch to the extended state.

[0077] Through the above technical solution, the second part 22 can be positioned on the installation assembly 1 through the locking cooperation between the locking member 42 and the locking mechanism 41, thereby ensuring the stability of the second part 22 in the storage state.

[0078] Reference Figure 2 , Figure 5 and Figure 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 portion 411 and an unlocking portion 412. The locking portion 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 portion 411 is locked with the locking member 42, and in the unlocked position, the locking portion 411 is disengaged from the locking member 42.

[0079] The unlocking portion 412 is disposed below the locking portion 411 , and the unlocking portion 412 is connected to the locking portion 411 to at least control the locking portion 411 to be disengaged from the locking member 42 .

[0080] The above technical solution facilitates the user to perform the unlocking operation by lowering the height of the unlocking portion 412. When the user needs to use the ladder 100, the unlocking portion 412 can be used to control the locking portion 411 to disengage from the locking member 42, that is, to release the restriction on the second part 22, so that the second part 22 can be rotated to extend out of the mounting assembly 1.

[0081] In some specific embodiments, the locking portion 411 includes a rotatable active locking tongue 4111 and a locking tongue spring. The active locking tongue 4111 is rotatably disposed on the mounting assembly 1, and a locking member 42 is disposed on the second end of the second portion 22. The locking member 42 is configured as a first locking ring 421. When the second portion 22 is rotated to be received in the mounting assembly 1, the active locking tongue 4111 is rotated to be at least partially inserted into the first locking ring 421 to limit the movement of the first locking ring 421, thereby positioning the second portion 22 on the mounting assembly 1.

[0082] The lock tongue spring is connected to the movable lock tongue 4111 and the mounting assembly 1 respectively. The lock tongue spring applies a force to the movable lock tongue 4111 to rotate toward the locking position, thereby ensuring that the movable lock tongue 4111 can be stably inserted into the first lock ring 421 .

[0083] Reference Figure 6 , Figure 8and Fig.14 Specifically, the unlocking portion 412 includes an opening handle 4121 rotatably arranged on the mounting assembly 1. The opening handle 4121 is connected to the movable locking tongue 4111 through a pulling member 4122. By depressing the opening handle 4121, the pulling member 4122 can be driven to move. The pulling member 4122 drives the movable locking tongue 4111 to rotate to disengage from the first locking ring 421, thereby releasing the restriction on the second part 22, and the second part 22 can be rotated to extend out of the first part 21.

[0084] In some embodiments, a lock structure 13 is further provided on the mounting assembly 1 , and the lock structure 13 is configured to lock the position of the pulling member 4122 or unlock the pulling member 4122 .

[0085] The lock body structure 13 is suitable for locking the pulling member 4122 to limit the movement of the pulling member 4122, thereby preventing other people from accidentally touching the opening handle 4121, thereby preventing the risk of the second part 22 extending out of the installation component 1.

[0086] In some specific embodiments, the lock body structure 13 includes a lock core structure 131 and a lock core paddle 133 linked to the lock core structure 131. The lock core structure 131 is rotatably disposed on the mounting assembly 1 and connected to the lock core paddle 133 to drive the lock core paddle 133 to rotate. The lock core paddle 133 is suitable for contacting with the pull member 4122 to lock the pull member 4122 or separating from the pull member 4122. The specific manner in which the lock core paddle 133 locks the pull member 4122 may be that a part of the lock core paddle 133 is engaged with the pull member 4122, or the lock body paddle 133 is stopped against the pull member 4122 to limit the movement of the pull member 4122 by friction, or other limiting manners, which are not limited in the present application.

[0087] The lock core structure 131 has a key 132 adapted thereto. When the ladder 100 needs to be unfolded, the key 132 is first inserted into the lock core structure 131, and the key 132 is turned so that the lock core paddle moves in a direction away from the pulling member 4122 under the drive of the lock core torsion spring of the lock core structure 131, thereby releasing the restriction on the pulling member 4122. The opening handle 4121 is pressed without releasing the key 132, and the opening handle 4121 drives the pulling member 4122 to produce a stroke displacement. The pulling member 4122 drives the movable lock tongue 4111 to rotate to disengage from the first lock ring 421, thereby releasing the restriction on the second part 22, and the second part 22 can be rotated to extend out of the first part 21.

[0088] Reference Figure 2 , Figure 5 and Figure 6In some embodiments, the second limiting component 4 also includes an elastic clamping member 43 and a mating member 44, one of the elastic clamping member 43 and the mating member 44 is arranged on the mounting component 1 and the other is arranged on the second part 22, and in the storage 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.

[0089] The elastic clamping member 43 may be arranged on the installation component 1 and the matching member 44 may be arranged on the second part 22 , or the elastic clamping member 43 may be arranged on the second part 22 and the matching member 44 may be arranged on the installation component 1 , as long as the elastic clamping member 43 clamps the matching member 44 to buffer the vibration of the second part 22 .

[0090] In some embodiments, the elastic clamping member 43 at least includes an elastic clamping groove, and the matching member 44 is a matching protrusion protruding from the second part 22, and the matching protrusion abuts against the inner wall of the clamping groove in the storage state. The second part 22 is rotated until the matching protrusion is inserted into the clamping groove to realize the connection between the elastic clamp and the matching member 44, which reduces the difficulty of operation, and the inner wall of the clamping groove abuts against the matching protrusion, which can buffer the rotation of the second part 22 from multiple angles, further reducing the risk of abnormal noise of the second part 22.

[0091] In some specific embodiments, the mating piece 44 is constructed as a second locking ring 441 arranged 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 piece 43 is defined by a clamping groove adapted to the second locking ring 441. When the second part 22 is rotated until the first locking ring 421 is matched with the locking structure, the second locking ring 441 is inserted into the clamping groove of the elastic clamping piece 43.

[0092] In the above technical solution, the elastic clamping member 43 and the matching member 44 have simple structures, which reduces the cost of the ladder 100.

[0093] Reference Fig. 9 , Fig.10 and Fig.11 In some embodiments, the extended state includes a first state, in which the first portion 21 is received in the mounting assembly 1 and the second portion 22 is rotated to extend from the first portion 21 and the mounting assembly 1 .

[0094] When the user needs to use the ladder 100, the user first releases the limit imposed on the second portion 22 by the second limit assembly 4, so that the second portion 22 can rotate to extend out of the first portion 21 and the mounting assembly 1. At this time, the ladder 100 is in the first state. Then, the user releases the limit imposed on the first portion 21 by the first limit assembly 3, so that the first portion 21 can rotate to extend out of the mounting assembly 1, thereby completely switching the ladder 100 to the extended state.

[0095] In some embodiments, the mounting assembly 1 is provided with an elastic stop member 14. In a first state, the elastic stop member 14 abuts against 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.

[0096] Through the above technical solution, in the first state, the elastic stop member 14 stops the second part 22, limiting the continued rotation of the second part 22 and avoiding the second part 22 from colliding with the vehicle body 7. When the first part 21 rotates to extend out of the mounting assembly 1, the first part 21 drives the second part 22 to move in a direction away from the mounting assembly 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 until it is spliced ​​with the end of the first part 21.

[0097] In some specific embodiments, the elastic stop member 14 is disposed at the bottom end of the mounting assembly 1, and the elastic stop member 14 is constructed so that when the second part 22 rotates to 155° in the first state, it stops against the elastic stop member 14 to prevent the second part 22 from scratching the vehicle paint when flipping.

[0098] Reference Figure 3 , Figure 4 and Fig.14 In some embodiments, the connecting rod 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 abuts against the second stop member 15 to limit the rotation range of the connecting rod assembly 5.

[0099] In the extended state, the first stop member 54 abuts against the second stop member 15 to limit the downward rotation of the connecting rod assembly 5, thereby ensuring the stability of the first part 21 in the extended state and ensuring the reliability of the ladder 100 when used by the user.

[0100] In some embodiments, the first stop member 54 includes a first stop pin 541 that passes through the connecting rod assembly 5, and the second stop member 15 includes a mounting seat 151 for installing a rotating pin. The connecting rod assembly 5 is rotatably connected to the mounting assembly 1 through the rotating pin, and the first stop pin 541 contacts the mounting seat 151 to limit the rotation range of the connecting rod assembly 5.

[0101] In the above technical solution, the mounting seat 151 is directly formed as the second stop member 15, and there is no need to set up other structures, which is conducive to the simplification of the structure of the ladder 100, and the first stop pin 541 is passed through the connecting rod assembly 5, which ensures the stability of the connection between the first stop pin 541 and the connecting rod assembly 5. When in the extended state, the first stop pin 541 can be stably supported on the mounting seat 151, ensuring the reliability of the user when using the ladder 100.

[0102] In some specific embodiments, the first connecting rod 51 is rotatably connected to the mounting assembly 1 via the first rotating pin 511, and the second connecting rod 52 is rotatably connected to the mounting assembly 1 via the third rotating pin 521. The first connecting rod 51 and the second connecting rod 52 are both provided with a first stop pin 541, and the mounting seat 151 of the first rotating pin 511 and the mounting seat 151 of the third rotating pin 521 are both formed as a second stop member 15.

[0103] In the extended state, the first counter-pin 541 on the first connecting rod 51 abuts against the mounting seat 151 of the first rotating pin 511 to limit the rotation of the first connecting rod 51, and the first counter-pin 541 on the second connecting rod 52 abuts against the mounting seat 151 of the third rotating pin 521 to limit the rotation of the second connecting rod 52, thereby limiting the rotation of the connecting rod assembly 5 and ensuring the stability of the first part in the extended state.

[0104] In the storage state, the connecting rod assembly 5 abuts against the mounting assembly 1, thereby limiting the rotation of the connecting rod assembly 5 and ensuring the stability of the first part in the storage state.

[0105] 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.

[0106] 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 rotation pin 512 (first limiting rod 31 ), which reduces the difficulty of installing the tension spring 513 .

The lower mounting member 162 is suitable for being mounted on the side of the vehicle body 7 through a plurality of fasteners, which effectively ensures the firmness of the connection between the mounting assembly 1 and the vehicle body 7.

[0109] In some embodiments, the ladder 100 also includes: a shielding assembly, which is detachably connected to the mounting assembly 1 and shields the mounting portion 16 of the mounting assembly 1, thereby preventing the mounting portion 16 from leaking out and ensuring the aesthetics of the vehicle 200. It can also block rainwater from flowing toward the mounting portion 16, thereby reducing the risk of water entering the vehicle body 7. When it is necessary to disassemble the ladder 100 from the vehicle body 7, the shielding assembly is first removed to expose the mounting portion 16 to facilitate the user to perform the disassembly operation of the mounting portion 16.

[0110] In some embodiments, the shielding assembly includes an upper decorative cover, which is detachably connected to the upper mounting member 161 through the cooperation of snaps and mushroom buckles with the mounting assembly 1, and covers the upper mounting member 161 to prevent the upper mounting member 161 from being exposed.
