Description

Technical Field

[0001] This utility model relates to the field of special vehicle facilities, specifically to a folding and flipping step inside a vehicle door. Background Technology

[0002] In motorhomes and special-purpose vehicles, steps are typically installed to facilitate entry and exit. Traditional steps are usually mounted on the floor of the vehicle. This installation method directly encroaches on interior space, especially in small vehicles. The already limited interior space is further compressed by fixed steps, resulting in significant wasted space and affecting the vehicle's layout and usability. Furthermore, the fixed angle of the steps cannot be adjusted according to different parking positions or personnel entry / exit directions, failing to meet the requirements for flexibility and causing considerable inconvenience for personnel entering and exiting the vehicle. In addition, even some foldable step structures, when folded up and stored on the floor, still occupy interior space.

[0003] Therefore, there is an urgent need for a door step structure that can be stably unfolded when in use, tightly folded when not in use, and eliminate gaps with the passenger compartment floor, in order to improve the safety, space utilization efficiency, and flexibility of vehicle step use. Utility Model Content

[0004] The purpose of this utility model is to provide a folding and flipping step inside a car door to solve the above-mentioned problems. When not in use, the step can be folded upwards and fitted to the inside of the car door, without encroaching on the interior space and improving space utilization efficiency. When in use, the step can be quickly unfolded by pushing open the car door and unlocking it. It is convenient to operate and has multiple advantages such as space utilization, operation, safety and structural stability, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a folding and flipping step inside a car door, including a car body and a car door. One side of the car door is rotatably connected to the outer edge of the car body to form a hinged swing door. It also includes a folding step disposed on the side of the car door near the car body. The folding step includes a fixed plate disposed on the car door. A movable plate is disposed parallel to the outer side of the fixed plate. The movable plate and the fixed plate are inclined plate structures with stepped top edges. Multiple step plates that rise layer by layer are hinged between the movable plate and the fixed plate. The movable plate and the step plates form a folding step mechanism that flips upward and fits against the inner side of the car door with the fixed plate as support.

[0006] When using the aforementioned folding step inside the car door, to open the car door and unfold the step, push the car door outward and release the locking mechanism to the guardrail. At this time, the guardrail and the folding step unfold outward under their own weight until the step is horizontal. Adjust the length of the outrigger extending downward until the bottom of the outrigger touches the bottom surface, completing the unfolding action of the folding step. To fold the step, lift the guardrail upward so that the multiple step plates fold upward simultaneously under the support of the fixed plate until the multiple step plates rotate and fit against the inside of the door panel, so that the folding step is tightly folded up inside the car door. Lock the position of the guardrail with the connector, and then quickly fold up and fix the folding step, ensuring that the step at the car door does not encroach on the interior space. If the door opens outward at an angle exceeding 90 degrees, a gap is formed between the top step and the car floor. In this state, the top step is pushed and rotated towards the car floor under the support of the pivot, so that the top step extends to the top surface of the car floor. The top step covers the gap between the step and the car floor, thereby increasing the coverage area of ​​the top step and improving the safety of stepping on it at the connection between the folding step and the car floor.

[0007] Preferably, the system also includes a guardrail frame, which includes two parallel uprights fixed to the top edge of the movable plate, with handrails connected to the top of the two uprights, and the handrails are inclined along the extension direction of the step plate.

[0008] Preferably, it also includes a connector fixed to the inside of the door, the connector being used to detachably lock the guardrail frame to maintain the folded state of the folding steps.

[0009] Preferably, the connector is a U-shaped clip structure that snaps into the upright, and a shock-absorbing pad that abuts against the upright is provided on the inner side of the opening of the connector.

[0010] Preferably, the connector is a Velcro fastener fixed to the inside of the car door in the middle, and the end of the connector is wrapped around the outer circumference of the upright and can be peeled off and adhered to any position along the length of the outer side of the connector.

[0011] Preferably, the movable plate is provided with height-adjustable support legs on both the front and rear sides of its bottom edge, and the support legs are connected to the movable plate by threads.

[0012] Preferably, the top surface of the vehicle interior floor is flush with the top surface of the topmost step of the folding steps.

[0013] Preferably, the uppermost step plate includes a lower plate that is hinged to the opposite sides of the fixed plate and the movable plate. An upper plate is arranged parallel above the lower plate. A pivot is provided on the rear side of the lower plate near the corner of the door panel to support the rotation of the upper plate. The pivot is used to support the upper plate to rotate to the gap between the folding step and the carriage floor as a suspension pad.

[0014] The beneficial effects are as follows: 1. This utility model is designed with a folding step that can be flipped up and retracted to the inside of the car door. When not in use, the folding step can be folded up and attached to the inside of the car door. The guardrail position is locked by the connector, which can be quickly folded up and fixed without taking up the interior space. This effectively improves the utilization efficiency of vehicle space, and is especially suitable for small vehicles with narrow spaces.

[0015] 2. When the folding step is needed, push the car door outward to release the locking of the connecting piece to the guardrail. The guardrail and the folding step can unfold outward under their own weight. Adjust the length of the outriggers so that the bottom end touches the ground to quickly complete the unfolding action. The operation is simple and convenient.

[0016] 3. When the door opens outward at an angle exceeding 90 degrees, creating a gap between the top step and the carriage floor, the top step can be pushed and rotated towards the carriage floor under the support of a pivot. This covers the gap, expands the coverage area of ​​the top step, improves the safety of stepping on the folding step and the carriage floor, and reduces the risk of people falling or getting their feet stuck when entering or exiting the carriage.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] See Figures 1-8 As shown, this utility model provides a folding and flipping step inside a car door, including a car body 1 and a car door 2. The car door 2 is rotatably connected to the outer edge of the car body 1 to form a hinged swing door. Therefore, it also includes a folding step 4 set on the side of the car door 2 near the car body 1. The folding step 4 includes a fixed plate 401 set on the car door 2. A movable plate 402 is arranged parallel to the outer side of the fixed plate 401. The movable plate 402 and the fixed plate 401 are inclined plate structures with stepped top edges, thus providing a suitable support base for the installation and flipping of the step plate 403. Multiple step plates 403 that rise layer by layer are hinged between the movable plate 402 and the fixed plate 401. The movable plate 402 and the step plates 403 form a folding step mechanism that flips upward and fits against the inner side of the car door 2 with the fixed plate 401 as support, thereby realizing the function of unfolding when in use and folding when not in use, saving space.

[0022] As an optional implementation, a guardrail frame 5 is also included. The guardrail frame 5 includes two parallel uprights 501 fixed to the top edge of the movable plate 402. The top of the two uprights 501 is connected to a handrail 502. The handrail 502 is inclined along the extension direction of the step plate 403 to facilitate gripping by personnel. With this configuration, the uprights 501 and handrail 502 of the guardrail frame 5 can provide stable support and protection for personnel to step up and down, improving safety when getting on and off the vehicle. It also includes a connector 6 fixed to the inside of the door 2. The connector 6 is used to detachably lock the guardrail frame 5 to keep the folded step 4 in the folded state, thereby preventing the folded step 4 from being accidentally unfolded during vehicle operation. The connector 6 is a U-shaped clip structure or Velcro. Specifically, when the connector 6 is a U-shaped clip structure that engages with the upright 501, a shock-absorbing pad is provided on the inner side of the opening of the connector 6 to press against the upright 501. This design can effectively reduce friction and vibration between the upright 501 and the connector 6, avoid noise, and enhance the stability of locking. When the connector 6 is a Velcro fastener fixed to the inner side of the door 2 in the middle, the end of the connector 6 is wrapped around the outer circumference of the upright 501 and can be peeled off and glued to any position along the length of the outer side of the connector 6. This design allows for flexible adjustment of the wrapping and bonding position of the Velcro according to the position of the upright 501, enabling quick locking and unlocking of the guardrail frame 5. Preferably, the U-shaped clip structure can more quickly lock the upright 501, thereby enabling convenient locking and unfolding of the guardrail frame 5 and the folding step 4.

[0023] The movable plate 402 is equipped with height-adjustable support legs 402a on both the front and rear sides of the bottom edge. The support legs 402a are connected to the movable plate 402 by threads, so that the length of the support legs 402a extending out of the movable plate 402 can be adjusted according to different ground conditions, so that the bottom end of the support legs 402a can stably abut against the bottom surface, ensuring the stability of the folding step 4 after it is unfolded. The top surface of the carriage floor 3 on the inner side of the vehicle body 1 is flush with the top surface of the uppermost step plate 403 of the folding step 4, ensuring a smoother transition for personnel from the step plate 403 to the carriage floor 3 and reducing the risk of tripping. The uppermost step plate 403 includes a lower plate 403a that is hinged to the opposite sides of the fixed plate 401 and the movable plate 402 respectively. An upper plate 403b is arranged parallel above the lower plate 403a. A pivot 403c is provided on the rear side of the lower plate 403a near the corner of the door panel to support the rotation of the upper plate 403b. The pivot 403c is used to support the upper plate 403b to rotate into the gap between the folding step 4 and the carriage floor 3 as a suspension pad. Thus, when the door 2 opens at a large angle and a gap is formed between the folding step 4 and the carriage floor 3, the upper plate 403b is used to cover the gap, expanding the coverage area of ​​the uppermost step plate 403, improving stepping safety, and preventing personnel from getting their feet stuck or falling.

[0024] With the above structure, when it is necessary to open the car door 2 and unfold the folding step 4, push the car door 2 outward to the outside of the car body 1 and release the locking of the guardrail frame 5 by the connector 6. At this time, the guardrail frame 5 and the folding step 4 unfold outward under their own weight until the step plate 403 is in a horizontal state. At this time, adjust the length of the support leg 402a extending downward from the movable plate 402 until the bottom end of the support leg 402a touches the bottom surface, completing the unfolding action of the folding step 4. When it is necessary to fold up the folding step 4, lift the guardrail frame 5 upward so that the multi-layer step plate 403 folds up synchronously under the support of the fixed plate 401 until the multi-layer step plate 403 rotates and fits against the inside of the door panel, so that the folding step 4 is tightly folded up inside the car door 2. The position of the guardrail frame 5 is locked by the connector 6, and then the folding step 4 is quickly folded up and fixed, ensuring that the step at the car door 2 does not encroach on the interior space. If the door 2 opens outward at an angle exceeding 90 degrees, a gap is formed between the top step 403 and the car floor 3. In this state, the upper plate 403b is pushed and rotated towards the car floor 3 under the support of the pivot 403c. The upper plate 403b is rotated to extend to the top surface of the car floor 3, and the gap between the step 403 and the car floor 3 is covered by the upper plate 403b, thereby expanding the coverage area of ​​the top step 403 and improving the stepping safety at the connection between the folding step 4 and the car floor 3. By setting a folding step 4 that can be flipped up and retracted to the inside of the door 2, when not in use, the folding step 4 can be folded up and fitted to the inside of the door 2. The guardrail frame 5 is locked in place by the connector 6, which can be quickly folded up and fixed without taking up interior space. This effectively improves the utilization efficiency of vehicle space, and is especially suitable for small vehicles with narrow spaces.

[0025] When the folding step 4 is needed, push the car door 2 outward to release the locking of the connecting piece 6 to the guardrail 5. The guardrail 5 and the folding step 4 can unfold outward under their own weight. Adjust the length of the outrigger 402a so that the bottom end touches the bottom surface to quickly complete the unfolding action. The operation is simple and convenient.

[0026] When the door 2 opens outward at an angle exceeding 90 degrees, creating a gap between the top step 403 and the carriage floor 3, the top plate 403b can be pushed and rotated towards the carriage floor 3 under the support of the pivot 403c. This covers the gap, expands the coverage area of ​​the top step 403, improves the safety of stepping on the folding step 4 at the connection with the carriage floor 3, and reduces the risk of people falling or getting their feet stuck when entering or leaving the carriage.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
