[0031] It should be noted that the modification of "one" and "multiple" mentioned in the present application is illustrative and not limiting, and those skilled in the art should understand that unless otherwise explicitly indicated in the context, it should be understood as "one or more".
[0032] In the related art, for the current pickup and other vehicle models, when the box door 400 of the vehicle rear compartment is opened to the horizontal state, due to the high distance between the box door 400 and the ground, personnel getting on and off the vehicle often adopts two ways:
[0033] The first way: the user needs to stand on the ground first, hold the edge of the box door 400 or the auxiliary handle on the side of the vehicle with both hands, then lift the leg, step one foot onto the plane of the box door 400, and then lift the other foot with force, finally enter the rear compartment. When getting off the vehicle, the user needs to operate in reverse, first move one foot from the plane of the box door 400 to the ground, and then slowly put down the other foot. This way of getting on and off the vehicle not only requires certain physical strength and flexibility, but also is easy to lose balance during operation, which has certain safety hazards, especially for the elderly, children or the disabled, the difficulty and risk of getting on and off the vehicle are more prominent.
[0034] The second way: when the personnel get on and off the vehicle, the personnel usually use an independent step ladder as an auxiliary tool. However, the step ladder has no special cooperation with the vehicle rear compartment, and when used, the step ladder is prone to sliding and falling due to unstable placement, thereby causing safety hazards. In addition, since the step ladder needs to be stored separately, the step ladder usually occupies a large storage space of the vehicle rear compartment, which brings inconvenience to the user.
[0035] In view of the above problems, the utility model provides a step ladder device, including guide rail device 100 and step ladder platform 200, the guide rail device 100 includes first guide rail piece 101 and second guide rail piece 102, the first guide rail piece 101 and the second guide rail piece 102 are configured to be slidably connected with the box door 400, one end of the first guide rail piece 101 is connected with the step ladder platform 200, and the other end is rotatably connected with the second guide rail piece 102, when the rotating connection of the first guide rail piece 101 and the second guide rail piece 102 moves to the contour range outside the box door 400, the first guide rail piece 101 is configured to rotate relative to the second guide rail piece 102, so that the step ladder platform 200 is located below the box door 400.
[0036] It should be understood that below the box door 400 refers to the area with a height lower than the box door 400, that is, the position below the lowest end of the box door 400 in the spatial position.
[0037] Specifically, as shown in Figure 1 , 2 The guide rail device 100 includes two parts, i.e., the first guide rail piece 101 and the second guide rail piece 102; wherein one end of the first guide rail piece 101 is directly or indirectly fixed with the step ladder platform 200, and the other end is rotatably connected with the second guide rail piece 102 through a rotating shaft, which can be used to change the position of the step ladder platform 200; at the same time, the first guide rail piece 101 and the second guide rail piece 102 are used to be slidably connected with the box door 400, and can change their own positions relative to the box door 400.
[0038] In the embodiment, in the normal state, the extension directions of the first guide rail piece 101 and the second guide rail piece 102 are the same and both can slide relative to the box door 400 along the extension directions. When the personnel need to enter the vehicle rear compartment, the box door 400 of the vehicle rear compartment is first opened to the horizontal state, and then the step ladder platform 200 is pulled to make the first guide rail piece 101 and the second guide rail piece 102 slide along the box door 400. As the rotating connection of the first guide rail piece 101 and the second guide rail piece 102 moves to the contour range outside the box door 400, the first guide rail piece 101 is separated from the vehicle compartment and can rotate relative to the second guide rail piece 102, so that the step ladder platform 200 is moved to below the box door 400. In this way, the stepping position of the personnel getting on and off the vehicle can be lowered, thereby effectively reducing the difficulty of the personnel getting on and off the vehicle rear compartment.
[0039] Meanwhile, compared with using an independent bicycle ladder as an auxiliary tool, the bicycle ladder device of the embodiment is connected with the box door 400, and the probability of slippage of the bicycle platform 200 is reduced, thereby reducing the security risks. In addition, the bicycle ladder device of the embodiment can be used through two-step operations of pulling and rotating, and the operation is convenient.
[0040] In the embodiment, the force-bearing components of the bicycle ladder device are made of stainless steel, which ensures that the bicycle ladder device can bear a large load during use, thereby ensuring the stability and reliability of the structure; and other non-force-bearing components can be made of plastic material. The plastic material is relatively light, and through reasonable collocation of such materials, the total weight of the bicycle ladder device can be effectively reduced on the premise of ensuring the overall performance of the bicycle ladder device, so as to meet the lightweight demand.
[0041] Further, the maximum rotation angle of the first guide rail 101 and the second guide rail 102 is not specifically limited and can be set according to actual use requirements, for example, can be 45 degrees, 60 degrees or 90 degrees, etc.
[0042] Optionally, the guide rail device 100 has a plurality of guide rail devices 100, and the first guide rail 101 of each of the plurality of guide rail devices 100 is connected with the bicycle platform 200.
[0043] Specifically, as shown in Figure 1 , 2 The guide rail device 100 can have two guide rail devices 100, and the first guide rail 101 of each of the two guide rail devices 100 is connected to the opposite ends of the bicycle platform 200. In this way, by providing two guide rail devices 100 and arranging the first guide rails 101 of the two guide rail devices 100 in parallel and at intervals at the opposite ends of the bicycle platform 200, the structural stability and load-bearing capacity of the bicycle platform 200 can be significantly improved. This design not only ensures that the bicycle platform 200 can bear force uniformly during use, avoiding deformation or damage caused by uneven local force, but also enhances its durability and reliability in frequent use.
[0044] In other embodiments, the number of guide rail devices 100 can also be three, four or other numbers, which is not limited here and is determined according to actual requirements.
[0045] Optionally, the bicycle ladder device further comprises a guide rail housing 300, which is configured to be fixedly connected with the box door 400; the guide rail housing 300 is provided with a slide 301, and the first guide rail 101 and the second guide rail 102 of the guide rail device 100 are slidingly arranged in the slide 301.
[0046] Specifically, the guide rail housing 300 is installed on the door 400 to achieve stable sliding and precise guidance of the first guide rail component 101 and the second guide rail component 102. For example... Figure 3 , 4 As shown in Figure 5, the guide rail housing 300 is generally elongated, and a slide rail 301 extending along its length is provided inside it; the first guide rail component 101 and the corresponding second guide rail component 102 extend into the slide rail 301 through the inlet of the slide rail 301 and can slide in the slide rail 301.
[0047] In this optional embodiment, during the movement of the first guide rail 101 and the second guide rail 102, the guide rail housing 300 not only effectively restricts the movement trajectory of the guide rail components, preventing them from deviating or shaking during sliding, thereby improving the operational stability and reliability of the entire device, but also prevents dust, debris, etc. from entering the slide 301 through the enclosing effect of the guide rail housing 300, reducing the possibility of jamming of the first guide rail 101 and the second guide rail 102.
[0048] It should be noted that when there are two or more guide rail devices 100, each guide rail device 100 is equipped with a guide rail housing 300 to achieve stable sliding and precise guidance of the first guide rail component 101 and the second guide rail component 102 in each guide rail device 100.
[0049] Optionally, the pedal platform 200 includes a base plate 201, a pedal 202, and an elastic reset member 203; the base plate 201 is fixedly connected to the first guide rail 101; the pedal 202 is rotatably disposed on the base plate 201; and the two ends of the elastic reset member 203 are respectively connected to the base plate 201 and the pedal 202.
[0050] Specifically, such as Figure 7 As shown, the outer contour of the base plate 201 is roughly rectangular, and the pedal 202 is rotatably positioned in the middle of the base plate 201 via a rotating shaft; the elastic reset member 203 is a torsion spring, which is sleeved on the rotating shaft of the pedal 202, and the torsion arms extending from both ends of the torsion spring abut against the base plate 201 and the pedal 202 respectively.
[0051] In the optional embodiment, when the first guide rail member 101 drives the pedaling platform 200 to rotate to the position, the fixed connection between the bottom plate 201 and the first guide rail member 101 provides a stable support basis for the pedaling platform 200, ensuring the firmness and reliability thereof during use. In addition, the pedal 202 is used as a treading part, and the rotating arrangement of the pedal 202 can adapt to the pedaling posture and force of different users, providing a more flexible operation experience. Furthermore, the arrangement of the elastic reset member 203 can not only automatically restore the pedal 202 to the initial position after the user pedals, reducing the tediousness of user operation, but also reduce the impact force of the pedal 202 during use through the elastic buffering effect, prolong the service life of the pedal 202 and the entire pedaling platform 200, and improve the comfort and safety of use.
[0052] In other embodiments, the elastic reset member 203 can also be a compression spring or elastic rubber, which is arranged between the pedal 202 and the bottom plate 201.
[0053] Optionally, the bottom plate 201 comprises a bottom plate support 204 and a fixing device 205 arranged on the bottom plate support 204; the first guide rail member 101 is fixedly connected with the bottom plate support 204 through the fixing device 205; the fixing device 205 comprises a first fixing member 2051 and a second fixing member 2052, both of which are connected with the bottom plate support 204; the first guide rail member 101 is provided with a fixing cavity 1011, and an end surface of the first guide rail member 101 facing the bottom plate support 204 is provided with a mounting port 1012 communicating with the fixing cavity 1011; the first fixing member 2051 is fixedly connected with the outer side wall of one end of the first guide rail member 101 facing the bottom plate support 204; and the second fixing member 2052 extends into the fixing cavity 1011 through the mounting port 1012 and is fixed.
[0054] Specifically, as shown in Figure 7 The outer contour shape of the bottom plate support 204 is generally rectangular, and the bottom plate support 204 is provided with a fixing device 205 at each end along the length direction, respectively, for fixing the first guide rail member 101 of the two guide rail devices 100. As shown in Figure 6As shown, the first guide rail piece 101 is in the shape of a long strip as a whole, and a fixing cavity 1011 is arranged inside one end of the first guide rail piece 101 facing the bottom plate support 204, and an installation opening 1012 is arranged on the end surface of the first guide rail piece 101 facing the bottom plate support 204 and in communication with the fixing cavity 1011; in one embodiment of the fixing device 205, the fixing device 205 includes a first fixing piece 2051 and a second fixing piece 2052, wherein the first fixing piece 2051 is an L-shaped plate, one end of which is connected to the outer side wall of one end of the first guide rail piece 101 facing the bottom plate support 204, and the other end is fixedly connected to the bottom plate support 204; the second fixing piece 2052 includes a connecting plate 20521 and a connecting block 20522 connected to the connecting plate 20521, the connecting plate 20521 is fixedly connected to the bottom plate support 204, and the connecting block 20522 extends into the fixing cavity 1011 of the first guide rail piece 101 through the installation opening 1012 and is fixed.
[0055] In this optional embodiment, the bottom plate support 204 provides basic support for the entire bottom plate 201, ensuring its structural strength and stability; secondly, the first fixing piece 2051 in the fixing device 205 is fixedly connected to the outer side wall of one end of the first guide rail piece 101 facing the bottom plate support 204, and this outer wall connection mode can effectively disperse the stress at the connection point, avoiding structural damage caused by local stress concentration, thereby prolonging the service life and improving the reliability of the connection. At the same time, at least a part of the second fixing piece 2052 is fixed in the fixing cavity 1011 of the first guide rail piece 101, and this combination of internal and external fixing further enhances the stability of the connection, so that the guide rail piece can better disperse stress when bearing external force, reducing the influence of vibration and impact on the connection part, thereby improving the vibration resistance and impact resistance of the entire device.
[0056] In other embodiments, the first fixing piece 2051 can also be a straight plate or a U-shaped plate, which is not specifically limited here and is determined according to actual needs. The second fixing piece 2052 can also only include the connecting block 20522 and completely extend into the inside of the corresponding first guide rail piece 101.
[0057] Further, the first fixing piece 2051, the second fixing piece 2052, and the first guide rail piece 101 are respectively provided with coaxial first pin holes, second pin holes, and third pin holes; in this way, when fixing the first guide rail piece 101, the fixing pin is sequentially inserted through the first pin hole of the first fixing piece 2051, the third pin hole of the first guide rail piece 101, and the second pin hole of the second fixing piece 2052, thereby realizing the connection of the first guide rail piece 101 with the first fixing piece 2051 and the second fixing piece 2052. This arrangement can reduce the number of fixing pins to save costs.
[0058] Optionally, the base plate 201 further includes a pedal bracket 206, which is mounted on the base plate bracket 204, and the pedal 202 is configured to rotate toward the pedal bracket 206 after being subjected to force.
[0059] Specifically, such as Figure 8 As shown, the pedal bracket 206 has an overall shape similar to an arc plate and is fixedly connected to the base plate bracket 204. At least a part of the pedal bracket 206 is located on the rotation path of the pedal 202. Thus, when the pedal 202 is rotated under force to the position of contact with the pedal bracket 206, the pedal bracket 206 supports the pedal 202. That is to say, the pedal 202 reaches the maximum rotation position and can no longer rotate. At this time, the pedal 202 is in a horizontal or approximately horizontal position, which facilitates the safety of people stepping on it.
[0060] Furthermore, such as Figure 8 As shown, the base plate 201 also includes a decorative panel 207 and a sealing strip 208. The decorative panel 207 is installed on the end face of the base plate bracket 204 away from the guide rail device 100, and the sealing strip 208 is disposed on the edge of the decorative panel 207.
[0061] In this optional embodiment, such as Figure 10 As shown, when the trolley step device is installed inside the door 400, generally only the end of the base plate bracket 204 away from the guide rail device 100 is exposed. In this case, the design of the decorative panel 207 not only enhances the aesthetic appearance of the door 400, making it visually cleaner and more harmonious, but also provides some protection for the outer end face of the base plate bracket 204, preventing corrosion or damage from the external environment. Simultaneously, the sealing strip 208, located at the edge of the decorative panel 207, effectively prevents dust, impurities, and moisture from entering the interior of the door 400 through the gap between the decorative panel 207 and the door 400. Furthermore, the sealing strip 208 reduces vibration and noise transmission caused by external factors, improving the overall user experience and stability of the device.
[0062] Optionally, the fixing device 205 further includes a first connecting frame 2053 and a second connecting frame 2054. The first connecting frame 2053 is fixedly connected to the base plate support 204 and has a receiving cavity 20531. A portion of the second connecting frame 2054 is located in the receiving cavity 20531 and has an installation channel 20541 through which the first guide rail 101 passes. Another portion of the second connecting frame 2054 is engaged with the first connecting frame 2053 and abuts against the first connecting frame 2053 along the length direction of the first guide rail 101.
[0063] Specifically, such as Figure 8As shown, the first connecting frame 2053 can be integrally formed with the bottom plate support 204 and is provided with a U-shaped accommodating cavity 20531, and the top of the first connecting frame 2053 on both sides of the accommodating cavity 20531 is provided with a limiting protrusion 20532; the middle part of the second connecting frame 2054 is mounted in the accommodating cavity 20531 and is provided with a mounting passage 20541 for the first guide rail piece 101 to pass through along the length direction of the first guide rail piece 101; the top of both ends of the second connecting frame 2054 is respectively provided with a clamping piece 20542, the clamping piece 20542 is clamped on the first connecting frame 2053 through a slot structure, and the two clamping pieces 20542 respectively abut against the two limiting protrusions 20532 along the length direction of the first guide rail piece 101.
[0064] In this optional embodiment, the first connecting frame 2053 is fixedly connected with the bottom plate support 204 and is provided with the accommodating cavity 20531, which provides a stable mounting basis and space constraint for the second connecting frame 2054, and ensures the firmness and reliability of the overall structure; secondly, a part of the second connecting frame 2054 is located in the accommodating cavity 20531 and is provided with the mounting passage 20541 for the first guide rail piece 101 to pass through, and since the second fixing piece 2052 is located behind the mounting passage 20541, this design not only guides the first guide rail piece 101 to pass through and be accurately mounted with the second fixing piece 2052, but also, another part of the second connecting frame 2054 is clamped on the first connecting frame 2053 and abuts against the first connecting frame 2053 along the length direction of the first guide rail piece 101, so that when the first guide rail piece 101 has a tendency to be off-loaded due to external force or vibration, the second connecting frame 2054 can disperse part of the acting force to the first connecting frame 2053, effectively preventing the first guide rail piece 101 from being loosened or displaced due to external force or vibration.
[0065] Optionally, the cycling platform 200 further comprises an unlocking device 209, and the cycling platform 200 is configured to be locked or unlocked with the box door 400 through the unlocking device 209.
[0066] Specifically, the unlocking device 209 can be arranged on the bottom plate 201, and the unlocking device 209 can adopt various structural forms to realize its function. For example, the unlocking device 209 can be a mechanical locking mechanism, which realizes locking or unlocking through rotation or pressing operation. It can also be an electronic unlocking device 209, which controls the locking or unlocking operation by inputting a password or using an electronic key. Figure 7 As shown, the locking mechanism is a press-type unlocking, and the button is embedded in the bottom plate 201, and the locking and unlocking with the box door 400 are realized by operating the buckle.
[0067] In this optional embodiment, when the climbing ladder device needs to be used, the user can operate the unlocking device 209 to unlock the bottom plate 201 from the box door 400, thereby switching the climbing ladder device from the locked state to the usable state.
