TECHNICAL FIELD

[0001] The utility model belongs to vehicle technical field, concretely relates to a side ladder inclination angle adjusting device and vehicle. BACKGROUND

[0002] The existing automobile side ladder is mainly used for facilitating users to load and unload goods on the roof or use the roof luggage rack. The existing side ladder on the market has many deficiencies, which are specifically as follows: the existing side ladder usually cannot adjust the inclination angle according to the shape of the vehicle and the use demand, so that the universality is poor and cannot adapt to the shape design of different vehicle models. SUMMARY

[0003] The utility model embodiment provides a side ladder inclination angle adjusting device and vehicle, which aims to adjust the inclination angle of the side ladder, so that the side ladder can match the external modeling of multiple vehicle models and improve the universality of the side ladder.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the technical scheme of: providing a side ladder inclination angle adjusting device, comprising:

[0005] a side ladder body, which has a lower mounting point at the lower end and an upper mounting point at the upper end; and

[0006] a support rod telescopic mechanism, which is installed on the vehicle body and connected to the upper mounting point and / or the lower mounting point; when the support rod telescopic mechanism is connected to the upper mounting point, the lower mounting point is hinged to the vehicle body; when the support rod telescopic mechanism is connected to the lower mounting point, the upper mounting point is hinged to the vehicle body;

[0007] The support rod telescopic mechanism is hinged to the upper mounting point and / or the lower mounting point, and pushes the side ladder body away from or close to the side of the vehicle body to tilt, so as to adapt to the shape of the side of the vehicle body.

[0008] In a realizable manner, the support rod telescopic mechanism is arranged on the roof, comprising a linear actuator and a moving plate, the linear actuator has a support rod connected to the moving plate, and the moving plate is hinged to the upper mounting point; the support rod pushes the side ladder body to tilt through the moving plate. Since the cross-sectional area of the support rod of the linear actuator is small, the moving plate arranged between the support rod and the side ladder body increases the stress area, thereby improving the supporting force of the support rod on the side ladder body, and ensuring the supporting stability and safety of the side ladder body when it is adjusted to a certain inclination angle.

[0009] With reference to the first aspect, in an implementable mode, the device further comprises an upper mounting base fixed to the roof; the upper mounting base has a receiving cavity, the linear actuator and the moving plate are arranged in the receiving cavity, and a supporting and guiding structure for guiding the moving plate is further arranged in the receiving cavity. This design makes the installation of the supporting rod telescopic mechanism more compact, reduces the occupied space, and takes into account the visual appearance of the whole vehicle; and the supporting and guiding structure ensures the stability and guiding property of the moving plate during the telescoping process, preventing the moving plate from deviating or shaking during the movement.

[0010] With reference to the first aspect, in an implementable mode, the supporting and guiding structure comprises a guide rail sliding groove and a sliding wheel, the guide rail sliding groove is arranged in the receiving cavity; the sliding wheel is arranged on the lower surface of the moving plate and slides along the guide rail sliding groove with the moving plate. This design makes the movement of the moving plate more stable, reduces friction and wear, and improves the durability and reliability of the device.

This structure design can connect the guide rail sliding groove and the moving plate through the first rotating shaft penetrating the long strip holes, not only ensuring that the moving plate can maintain a good linear trajectory when following the movement of the sliding wheel, but also preventing the risk of the moving plate detaching from the upper mounting base, improving the firmness of the moving plate as a connecting piece between the supporting rod and the side ladder body, thereby ensuring the safety and reliability of the side ladder body when bearing weight.

[0012] With reference to the first aspect, in an implementable mode, a limiting plate is formed on the side of the upper mounting base close to the side ladder body, one end of the guide rail sliding groove abuts against the limiting plate; an avoiding window is formed on the limiting plate, the moving plate has an extension part extending out of the avoiding window, the lower surface of the extension part is provided with an extension plate, the supporting rod is connected to the extension plate; and the extension plate is hinged to the upper mounting point through a second rotating shaft. This embodiment constitutes a limiting structure of the moving plate through the side wall of the upper mounting base, which design limits the movement range of the moving plate by the limiting plate. This limiting by the limiting plate is mechanical limiting, which can prevent the risk of device damage caused by excessive movement of the moving plate due to failure or malfunction of the linear actuator controlled by air or electricity.

[0013] With reference to the first aspect, in a possible implementation manner, a telescopic protective cover is arranged between the side ladder body and the limiting plate; the telescopic protective cover can be telescoped with different inclination angles of the side ladder body. The telescopic protective cover can prevent the device from being eroded by dust, rain and other external environments, and also avoids the appearance discomfort caused by the exposed connecting components between the supporting rod telescoping mechanism and the side ladder body, thereby ensuring the activity, sealing and aesthetics of the device.

[0014] With reference to the first aspect, in a possible implementation manner, a protective cover is arranged on the upper mounting seat, and the supporting rod telescoping mechanism and the telescopic protective cover are both covered below the protective cover. In this way, there is no exposed component outside the whole device, which avoids the risk that the linear actuators, guide rails and sliding wheels are blown by wind and rain and fail.

[0015] With reference to the first aspect, in a possible implementation manner, the supporting rod telescoping mechanism includes two linear actuators and a moving plate; the two linear actuators correspond to two side columns of the side ladder body respectively. Two guide rails and two sliding wheels are arranged in the accommodating cavity to more accurately guide the movement track of the moving plate. This design enables the two sides of the side ladder body to be inclined synchronously, ensures the balance and stability of the side ladder during the inclination process, and avoids the problem of inconsistent inclination angles caused by uneven force on a single side.

[0016] The side ladder inclination angle adjusting device provided by the utility model has the beneficial effects that, by telescoping of the supporting rod, the inclination angle of the side ladder body can be flexibly adjusted according to the shapes of different vehicle sides, the side ladder body is inclined around the installation point below the side ladder body to approach the vehicle side or is inclined away from the vehicle side.

DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be described in further detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0034] Please refer to Figures 1 to 11 , the side ladder inclination angle adjusting device provided by the utility model will be described. The side ladder inclination angle adjusting device comprises a side ladder body 100 and a support rod telescopic mechanism. The lower end of the side ladder body 100 has a lower mounting point 101, and the upper end has an upper mounting point 102. The support rod telescopic mechanism is installed on the vehicle body and is connected to the upper mounting point 102 and / or the lower mounting point 101. The support rod telescopic mechanism provides power for the adjustment of the inclination angle of the side ladder body 100. The support rod telescopic mechanism is hinged to the upper mounting point 102 and / or the lower mounting point 101, pushes the side ladder body 100 to incline towards or away from the side of the vehicle body, and adapts to the shape of the side of the vehicle body.

[0035] When the support rod telescopic mechanism is connected to the upper mounting point 102, the lower mounting point 101 is hinged to the vehicle body. At this time, the support rod telescopic mechanism is installed on the vehicle body close to the upper end of the side ladder body 100, and the support rod is hinged to the upper mounting point 102. When the support rod is extended, it pushes the side ladder body 100 to be supported by the lower mounting point 101 and inclines away from the side of the vehicle body with the axis of the lower mounting point 101 as the center. When the support rod is retracted, it pushes the side ladder body 100 to be supported by the lower mounting point 101 and inclines towards the side of the vehicle body with the axis of the lower mounting point 101 as the center, so as to adapt to the shape of the side of the vehicle body. By adjusting the stroke of the extension or retraction of the support rod, the inclination angle of the side ladder body 100 can be adjusted, so as to adapt to different vehicle models.

[0036] When the support rod telescopic mechanism is selected to connect the lower mounting point 101, the upper mounting point 102 is hinged to the vehicle body; at this time, the support rod telescopic mechanism is mounted on the vehicle body near the lower end of the side ladder body 100, and the support rod is hinged to the lower mounting point 101; when the support rod is extended, the side ladder body 100 is pushed to be supported by the upper mounting point 102, and tilts in the direction away from the side of the vehicle body with the shaft of the upper mounting point 102 as the center; when the support rod is extended, the side ladder body 100 tilts in the direction close to the side of the vehicle body to adapt to the shape of the side of the vehicle body; by adjusting the stroke of the extension or retraction of the support rod, the angle of the side ladder body 100 can be adjusted, so as to adapt to different vehicle models.

[0037] When the lower mounting point 101 and the upper mounting point 102 of the side ladder body 100 are respectively connected to a support rod telescopic mechanism, the two support rod telescopic mechanisms can be simultaneously extended or retracted or one is extended and the other is retracted according to the shape of the side of the vehicle body, so as to adjust the inclination angle of the side ladder body 100 and adapt to different vehicle models.

[0038] In the prior art, the side ladder is generally fixed to the side of the vehicle body and does not have the function of adjusting with the change of the shape of the vehicle body, so the side ladder can only adapt to one vehicle model, and different vehicle models need to be equipped with different side ladders, which also leads to repeated use and waste of resources; compared with the prior art, the side ladder inclination angle adjusting device provided in the embodiment has the following advantages:

[0039] First, the universality of the side ladder is realized. By the extension and retraction of the support rod, the side ladder body 100 can be tilted close to or away from the side of the vehicle body with the lower mounting point 101 as the center, and the inclination angle of the side ladder body 100 can be flexibly adjusted. This feature makes the side ladder inclination angle adjusting device no longer limited to the use of a single vehicle model, greatly improves its universality, and solves the technical problem that the existing side ladder cannot adjust the inclination angle according to the shape of the vehicle and the use demand, resulting in poor universality and inability to adapt to the shape design of different vehicle models.

[0040] In application, whether it is used in a car, an SUV (SUV stands for sport utility vehicle, or suburban utility vehicle, which is a vehicle with the space function of a travel car and the off-road ability of a truck) or a commercial vehicle, or other types of tank cars, engineering vehicles, etc., as long as there is a suitable mounting position on the side of the vehicle body, the device can be adapted and installed and work normally.

[0041] Secondly, installation is simple and convenient. The side ladder body 100 has only two hinge points, that is, only two installation points. Since the side ladder body 100 needs to be tilted at different angles, both the upper and lower hinge points are hinged to the vehicle body or to the support rod via pins. Therefore, when the same side ladder is installed on different vehicle models, after equipping it with a strut telescopic mechanism, the side ladder body 100 only needs to be installed at two points, making installation simple and convenient.

[0042] Moreover, from an installation perspective, the device has a compact structure and does not occupy excessive vehicle space. During vehicle manufacturing or modification, the side ladder tilt angle adjustment device can be easily installed in the appropriate position. This not only improves production efficiency but also reduces installation costs.

[0043] Third, this adjustment method is convenient to operate and does not require complicated tools or cumbersome steps. The tilt angle of the side ladder body 100 can be adjusted simply by extending or retracting the support rod. Moreover, due to the hinge point design at both ends of the side ladder body 100, the entire adjustment process is stable and reliable.

[0044] Moreover, this adjustable design brings more convenience to users. For example, when washing or repairing vehicles, adjusting the side ladder to a suitable angle can provide workers with a more comfortable and safer operating environment, improving work efficiency.

[0045] It should be noted that the embodiments described later in this specification are all based on the example of the strut telescopic mechanism being connected to the upper end of the side ladder body 100, and can be used as a reference for the implementation of the strut telescopic mechanism being connected to the lower end of the side ladder body 100.

[0046] In some embodiments, see Figures 1 to 4 As shown, the strut telescopic mechanism is mounted on the roof and includes a linear actuator 230 and a movable plate 300. The linear actuator 230 has a support rod connected to the movable plate 300, which is hinged to the upper mounting point 102 of the side ladder body 100. The support rod pushes the side ladder body 100 to tilt via the movable plate 300. This design allows the strut telescopic mechanism to provide stable support force, ensuring the stability and safety of the side ladder during tilting. Simultaneously, the use of the linear actuator 230 makes the adjustment of the tilt angle more precise and controllable.

[0047] The strut telescopic mechanism is mounted on the roof, providing ample installation space and making installation simple and convenient. For example, without considering the vehicle's appearance, one end of the linear actuator 230 can be directly mounted on the roof, and the support rod can extend and retract along the left and right directions of the vehicle body, pushing the movable plate 300 to move left and right, thus achieving the purpose of adjusting the tilt angle with the mounting point 101 below the side ladder body 100 as support.

[0048] Due to the small cross-sectional area of the support rod of the linear actuator 230, the force receiving area is increased by the movement plate 300 arranged between the support rod and the side ladder body 100, thereby improving the support strength of the support rod on the side ladder body 100, and ensuring the support stability and safety when the side ladder body 100 is adjusted to a certain inclination angle.

[0049] At the same time, considering that the side ladder body 100 is a frame structure, specifically having two parallel side columns, the two side columns can be hinged at the same time by arranging the movement plate 300, at this time, the movement plate 300 can be moved by one linear actuator 230 or two linear actuators 230, thereby ensuring that the side ladder body 100 is inclined at the same angle on both sides, and ensuring the stability, safety and adaptability of the side ladder body 100 after being inclined.

[0050] When it is necessary to adjust the inclination angle of the side ladder body 100, the linear actuator 230 starts to work to drive the support rod to perform the extension and retraction movement. Since the support rod is connected to the movement plate 300, and the movement plate 300 is hinged to the upper mounting point 102 of the side ladder body 100, when the support rod is extended and retracted, the movement plate 300 will move accordingly. With the movement of the movement plate 300, the side ladder body 100 is gradually inclined around a certain lower mounting point 101.

[0051] Optionally, the linear actuator 230 can adopt any one of the structures of a pneumatic support rod, an electric push rod, a hydraulic support rod, and a screw nut, and the linear actuator 230 has a support rod capable of extension and retraction.

[0052] In some embodiments, referring to Figures 1 to 3 , Figures 6 to 9 , the device comprises an upper mounting seat 200 mounted on the roof of the vehicle; the upper mounting seat 200 has a containing cavity, and the linear actuator 230 and the movement plate 300 are arranged in the containing cavity, wherein the linear actuator 230 is fixedly connected with the inner wall of the containing cavity, and the support rod is fixedly connected with the movement plate 300; the containing cavity is further provided with a support guide structure for guiding the movement of the movement plate 300. The upper mounting seat 200 provides a containing cavity for the linear actuator 230 and the movement plate 300, which makes the installation of the support rod extension and retraction mechanism more compact, reduces the occupied space, and at the same time considers the visibility of the appearance of the whole vehicle; and the support guide structure ensures the stability and guidance of the movement plate 300 during the extension and retraction process, preventing the movement plate 300 from deviating or shaking during the movement.

[0053] In some embodiments, referring to Figures 2 to 4 , Figures 6 to 11The support and guide structure includes a guide rail groove 220 and a sliding wheel 302. The guide rail groove 220 is arranged in the accommodating cavity. The sliding wheel 302 is arranged on the lower surface of the moving plate 300 and slides along the guide rail groove 220 with the moving plate 300. This design makes the movement of the moving plate 300 more stable, reduces friction and wear, and improves the durability and reliability of the device. The cooperation of the guide rail groove 220 and the sliding wheel 302 ensures the accurate guidance of the moving plate 300 during the extension and retraction process.

[0054] In addition, in order to further improve the smoothness of the sliding wheel 302, a special lubricating coating can be arranged on the surface of the sliding wheel 302. This coating can effectively reduce the friction coefficient between the sliding wheel 302 and the guide rail groove 220, making the moving plate 300 more smooth during the extension and retraction process, thereby improving the working efficiency of the entire device.

[0055] Optionally, the support and guide structure includes a guide rail fixed to the bottom of the accommodating cavity and a sliding block fixed to the lower surface of the moving plate 300. The sliding block and the guide rail are in sliding cooperation. During operation, the pneumatic support rod drives the support rod to extend, drives the moving plate 300 to move along the guide rail, and then drives the side ladder body 100 to adjust the inclination angle.

[0056] The following is a specific implementation of the support and guide structure in combination with different types of linear actuators 230:

[0057] Example one, pneumatic support rod and guide rail groove 220 structure

[0058] The pneumatic support rod is fixedly connected to the bottom of the accommodating cavity through a shaft, and the support rod of the pneumatic support rod is fixedly connected to the moving plate 300. The lower surface of the moving plate 300 is provided with a sliding wheel 302, and the moving plate 300 slides along the guide rail groove 220 through the sliding wheel 302 to adjust the inclination angle of the side ladder body 100. The extension and retraction of the pneumatic support rod can be automatically controlled by an electrical control system to accurately adjust the inclination angle. The advantage of this structure is that it is simple in structure, easy to realize automatic control, and has a large adjustment range of inclination angle.

[0059] Example two, hydraulic support rod and guide rail structure

[0060] Structure description: The support rod extension and retraction mechanism adopts a hydraulic support rod and a guide rail structure. One end of the hydraulic support rod is fixed to the bottom of the accommodating cavity, and the support rod of the hydraulic support rod is fixedly connected to the moving plate 300. The lower surface of the moving plate 300 is provided with a sliding wheel 302, and the moving plate 300 slides along the guide rail through the sliding block to adjust the inclination angle of the side ladder body 100. The hydraulic system can be accurately controlled by an electrical control unit to automatically adjust the inclination angle. The hydraulic system provides a large thrust, which is suitable for heavy side ladders and stable inclination angle adjustment.

[0061] Example 3: Electric push rod and guide rail groove 220 structure

[0062] The electric push rod is fixedly connected to the bottom of the receiving cavity via a shaft, and its support rod is fixedly connected to the movable plate 300. A sliding wheel 302 is provided on the lower surface of the movable plate 300, allowing the movable plate 300 to slide along the guide rail groove 220 via the sliding wheel 302, thus adjusting the tilt angle of the side ladder body 100. The extension and retraction of the electric push rod can be precisely controlled by a motor, achieving automatic adjustment of the tilt angle of the side ladder body 100. The length of the electric push rod can also be precisely controlled by a motor, achieving automatic adjustment of the tilt angle. The electric push rod offers high control precision and flexible tilt angle adjustment, making it suitable for various vehicle models.

[0063] Example 4: Screw nut and guide rail structure

[0064] The two ends of the lead screw are rotatably mounted on the opposing inner walls of the receiving cavity. A nut is screwed onto the lead screw. One end of the support rod is connected to the nut, and the other end is connected to the side ladder body 100. Driven by a motor, the lead screw causes the nut to move linearly along the lead screw, thereby causing the support rod to reciprocate, thus adjusting the tilt angle of the side ladder body 100. The transmission of the lead screw and nut can be precisely controlled by the motor, achieving automatic adjustment of the tilt angle. The lead screw and nut transmission has high precision, a self-locking function, and stable tilt angle adjustment, making it suitable for scenarios requiring high-precision adjustment.

[0065] In some embodiments, see Figure 8 and Figure 9 , Figures 10 to 11 The guide rail groove 220 has elongated holes 221 on its two groove walls, which extend along the sliding direction of the sliding wheel 302. The sliding wheel 302 is connected to the lower surface of the moving plate 300 through the first rotating shaft 303. The two ends of the first rotating shaft 303 pass through the corresponding elongated holes 221. This structural design, through the first rotating shaft 303 passing through the elongated hole 221, connects the guide rail groove 220 to the movable plate 300. In other words, it limits the movable plate 300 to the upper mounting base 200, preventing the movable plate 300 from tilting and the sliding wheel 302 from dislodging from the guide rail groove 220 when the side ladder body 100 is tilted and bearing weight. This structural design not only ensures that the movable plate 300 maintains a good linear trajectory when moving with the sliding wheel 302, but also prevents the movable plate 300 from detaching from the upper mounting base 200, improving the robustness of the connection between the movable plate 300 as a support rod and the side ladder body 100, thereby ensuring the safety and reliability of the side ladder body 100 under load. Furthermore, the elongated hole 221 guides and limits the sliding wheel 302, allowing it to move precisely along the direction of the elongated hole 221 during sliding, further improving the movement accuracy and stability of the movable plate 300.

[0066] When the support guide structure is a structure of sliding rail and sliding block, the I-shaped or T-shaped sliding rail can be used, and the sliding block is provided with I-shaped or T-shaped sliding groove. The cooperation of the sliding block and the sliding rail can prevent the moving plate 300 from being warped.

[0067] In some embodiments, referring to Figures 2 to 3 , Figures 6 to 9 The upper mounting seat 200 is a cavity structure with a receiving cavity, and a limiting plate 240 is formed on one side of the side ladder body 100, that is, the side wall of the receiving cavity. One end of the guide rail sliding groove 220 abuts against the limiting plate 240, and the other end of the guide rail sliding groove 220 abuts against the side wall of the receiving cavity relative to the limiting plate 240, thereby limiting the moving stroke of the sliding wheel 302 and the moving stroke of the moving plate 300 and the extension and contraction amount of the support rod. Meanwhile, a avoiding window 241 is formed in the limiting plate 240, so that the moving plate 300 is connected to the upper mounting point 102 at the upper end of the side ladder body 100 through the avoiding window 241. The moving plate 300 has an extension 304 extending out of the avoiding window 241, and the lower surface of the extension 304 is provided with an extension plate 301, so that the support rod is vertically connected to the extension plate 301. The extension plate 301 is hingedly connected to the upper end of the side ladder body 100 through a second rotating shaft.

[0068] The side wall of the upper mounting seat 200 constitutes the limiting structure of the moving plate 300, which limits the moving range of the moving plate 300. The limiting structure constituted by the limiting plate 240 is a mechanical limiting structure, which can prevent the device from being damaged due to the over-movement of the moving plate 300 caused by the failure of the linear actuator 230 controlled by the air or electricity. Meanwhile, the avoiding window 241 ensures that the moving plate 300 does not interfere with other components during movement, thereby improving the safety and reliability of the device.

[0069] In some embodiments, referring to Figures 1 to 3The telescopic protective cover 250 is arranged between the side ladder body 100 and the limiting plate 240 and can be telescoped with the change of the inclination angle of the side ladder body 100. In the embodiment, the telescopic protective cover 250 is added outside the upper mounting seat 200. The telescopic protective cover 250 is made of flexible material and avoids damage to the associated components caused by rigid connection. The telescopic protective cover 250 is arranged between the side ladder body 100 and the limiting plate 240 and can be telescoped with the change of the inclination angle of the side ladder body 100. The design not only protects the connecting components between the supporting rod telescoping mechanism and the side ladder body 100, prevents the erosion of the device by dust, rain and other external environments, and prolongs the service life of the device, but also avoids the appearance discomfort caused by the exposure of the connecting components between the supporting rod telescoping mechanism and the side ladder body 100, thereby ensuring the mobility, sealing and aesthetics of the device.

[0070] In some embodiments, referring to Figures 1 to 3 The upper mounting seat 200 is provided with a protective cover 210, and the supporting rod telescoping mechanism and the telescopic protective cover 250 are covered below the protective cover 210. The design further enhances the protection performance of the device, prevents damage to the supporting rod telescoping mechanism and the telescopic protective cover 250 by external environment, improves the durability and reliability of the device, and also avoids the appearance discomfort caused by the exposure of the supporting rod telescoping mechanism, thereby ensuring the mobility, sealing and aesthetics of the device.

[0071] In particular, by arranging the upper mounting seat 200 on the upper end of the side ladder body 100, the supporting rod telescoping mechanism can be accommodated in the upper mounting seat 200. Thus, there is no exposed component outside the whole device, which not only avoids the risk of failure of the linear actuator 230, the guide rail groove 220 and the sliding wheel 302 caused by wind and rain, but also greatly improves the convenience of carrying and installation. For example, when the side ladder is installed on a whole vehicle, the side ladder is carried to the installation site as a whole, and then the upper mounting seat 200 is fixed on the roof of the vehicle, and the lower mounting point 101 at the lower end of the side ladder body 100 is hinged to the vehicle body.

[0072] Specifically, the upper mounting seat 200 is provided with a reserved connecting hole 260, and the upper mounting seat 200 can be fixed on the roof of the vehicle through the reserved connecting hole 260.

[0073] In some embodiments, referring to Figures 1 to 4The supporting rod telescopic mechanism comprises two linear actuators 230 and a moving plate 300; the two linear actuators 230 correspond to two side columns of the side ladder body 100 respectively.
