Description

Technical Field

[0001] This utility model belongs to the field of automotive parts, and in particular, it is a foldable baffle for platform steps. Background Technology

[0002] In retractable vehicle platform step systems, a movable transition baffle is typically installed at the front end of the retractable platform to facilitate a safe and smooth transition for passengers, especially wheelchair users, from the ground to the step. This baffle unfolds simultaneously with the platform's extension to the working position, primarily to fill the gap or height difference between the platform's leading edge and the ground, effectively preventing missteps, trips, or debris from getting caught, thus improving safety and comfort when getting on and off the vehicle. Utility Model Content

[0003] This utility model provides a foldable baffle for platform steps. The baffle can be folded and stored at the front edge of two adjacent platform steps. This not only saves space and improves space utilization, but also covers the area between adjacent steps, providing a shielding and sealing function and improving the overall sealing of the step system.

By driving the linkage assembly to move, the baffle is driven to switch between the storage and unfolding states.

[0005] Preferably, the baffle is rotatably connected to the front end of the pedal via a hinge connector.

[0006] Preferably, the side of the pedal is provided with a bracket, and the bracket is provided with a first guide groove and a second guide groove. The connecting rod assembly is guided by the first guide groove and the second guide groove through guide members respectively.

[0007] Preferably, the first guide groove is an arc-shaped groove or a straight groove.

[0008] Preferably, the second guide groove is an arc-shaped groove or a straight groove.

[0009] Preferably, the guide member is rotatably connected to the connecting rod assembly.

[0010] Beneficial effects: This utility model provides a foldable baffle for platform steps, which has the following advantages: (1) This utility model utilizes the first guide groove and the second guide groove in cooperation with the linear drive component, so that when the drive component retracts, the baffle can be pulled upward by the linkage assembly and completely folded inward by the hinge, and vertically retracted close to the front end of the pedal, which fundamentally eliminates the structural interference problem in the storage state and greatly saves space.

[0011] (2) In this utility model, the vertically folded baffle closely adheres to the front edge of the pedal to form a support and shielding structure, which can provide additional vertical support for the upper platform pedal and effectively shield the gap between adjacent pedal layers, thus improving safety and aesthetics.

Detailed Implementation

[0013] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application. Example 1:

[0014] like Figure 1-2 As shown, this embodiment 1 discloses a foldable baffle for platform steps, comprising: Baffle 1 is rotatably connected to the front end of pedal 2; At least one set of connecting rod assemblies 3, the front ends of which are rotatably connected to the two ends of the bottom surface of the baffle 1 respectively; At least one set of linear drive components 4, the fixed end of the linear drive component 4 is rotatably connected to one side of the pedal 2, and its drive end is rotatably connected to the rear end of the linkage assembly 3 on the same side. By driving the linkage assembly to move, the baffle 1 is driven to switch between the storage and unfolding states.

[0015] In this invention, the linear drive component can be electrically, pneumatically, or hydraulically driven, such as an electric actuator, linear motor, linear cylinder, or hydraulic cylinder. Existing drive devices capable of linear reciprocating motion are all applicable. In this embodiment 1, the linear drive component is driven by a linear motor.

[0016] In this invention, the linkage assembly 3 can be a single set, disposed on only one side of the pedal 2, or two sets, disposed on both sides of the pedal 2 respectively, with the linear drive component 4 correspondingly installed on the same side. In this embodiment 1, the linkage assembly 3 and the linear drive component 4 are a single set, and the aforementioned rotational connections are all hinged.

[0017] In this embodiment 1, as Figure 2 As shown, the baffle 1 is rotatably connected to the front end of the pedal 2 via a hinge connector 5. This invention utilizes a hinge connector to further increase the outward extension distance of the baffle. Simultaneously, it allows the baffle to fold backward towards the pedal when retracted, perfectly solving the space interference problem during storage.

[0018] In this utility model, in order to facilitate the installation of the linkage assembly 3 and ensure the stability of the movement path of the linkage assembly 3, a bracket 6 is provided on the side of the pedal 2. The bracket 6 is provided with a first guide groove 6-11 and a second guide groove 6-21. The linkage assembly 3 is guided by the guide member 6-3 in cooperation with the first guide groove 6-11 and the second guide groove 6-21, and the linkage assembly 3 is rotatably connected to the guide member 6-3.

[0019] To enhance the structural rigidity of the support, achieve uniform load distribution, and improve the overall reliability and stability of the structure, in this embodiment 1, the structure of the support 6 can be, but is not limited to, the following structures. For example... Figure 3 As shown, the bracket 6 includes a first support plate 6-1 and a second support plate 6-2. The first support plate 6-1 and the second support plate 6-2 are arranged parallel to each other on the inner and outer sides of the connecting rod assembly 3. The first support plate 6-1 has a first guide groove 6-11, and the second support plate 6-2 has a second guide groove 6-21. The inner and outer sides of the connecting rod assembly 3 are respectively rotatably connected to guide members 6-3 (so that the connecting rod assembly 3 can rotate around the two guide members 6-3 respectively), and the two guide members 6-3 cooperate with the first guide groove 6-11 and the second guide groove 6-21 for guidance.

[0020] In this invention, the guide component 6-3 can be any existing guide component that can cooperate with the guide groove to achieve the guiding function, such as a flanged bearing, a guide roller, or a guide rod. In this embodiment 1, the guide component is a guide roller.

[0021] In this invention, the first guide groove 6-11 can be an arc-shaped groove or a straight groove. The second guide groove 6-21 can be an arc-shaped groove or a straight groove.

[0022] In order to better constrain the motion path of the linkage assembly 3 and adapt to more application scenarios, the specific structure of the first guide groove 6-11 and the second guide groove 6-21 can be selectively designed according to actual needs.

[0023] In this embodiment 1, to avoid interference with the ground during unfolding and lowering due to the baffle's excessive length, this invention designs the first guide groove 6-11 as a downward-curving arc groove and the second guide groove 6-21 as a straight groove inclined upward from front to back (defining the extension direction as front and the retraction direction as back), thereby achieving precise constraint on the baffle's movement path. The specific principle is as follows: A double guide groove, composed of a downward-curving arc groove and a backward-inclined straight groove, along with guide member 6-3, jointly constrains the movement path of the linkage assembly. The first guide groove (arc groove) allows the linkage assembly 3 to rise synchronously upward during the unfolding of the baffle 1, thus avoiding structural interference and ensuring the baffle unfolds smoothly to the ground. The curvature of this arc groove can be designed according to the required lifting height. The second guide groove (inclined straight groove) guides and stabilizes the movement direction of the linkage assembly. This design ensures that the baffle moves smoothly and without interference throughout the entire unfolding and retraction process, and that the terminal positioning is accurate.

[0024] In this invention, the connecting rod assembly 3 can be, but is not limited to, the following structures. For example... Figure 4 As shown, in order to improve the stability of the linkage assembly 3, the linkage assembly 3 includes a first connecting plate 3-1 and a second connecting plate 3-2, and the first connecting plate 3-1 and the second connecting plate 3-2 are arranged parallel to each other. The first connecting plate 3-1 and the second connecting plate 3-2 are respectively rotatably connected to the guide member 6-3 for guiding installation in conjunction with the first guide groove 6-11 and the second guide groove 6-21, respectively. The driving end of the linear drive member 4 is rotatably connected to the tail ends of the first connecting plate 3-1 and the second connecting plate 3-2.

[0025] In this utility model, the connecting rod assembly can also be designed as a single-sided connecting rod, with guide members 6-3 provided on both sides of the single-sided connecting rod.

[0026] The working principle of this utility model is as follows: The linear drive component 4 serves as the power source, directly driving the rear end of the connecting rod assembly 3 through its linear reciprocating motion. The connecting rod assembly 3 moves under the path constraints of the first support plate 6-1 and the second support plate 6-2: the guide component 6-3 (such as a flanged bearing) on ​​the first support plate 6-1 is installed in the first guide groove 6-11 (a downwardly curved arc groove), and the guide component 6-3 on the second support plate 6-2 is installed in the second guide groove 6-21 (a straight groove that slopes upward from front to back). The first guide groove 6-11 and the second guide groove 6-21 cooperate to restrict the movement trajectory of the connecting rod assembly to a specific composite path. When the linear drive component 4 extends, it pushes the connecting rod assembly 3 to move forward and downward along the first guide groove 6-11 and the second guide groove 6-21. Its front end, through a rotational connection, pushes the baffle 1 to rotate outward and upward around the axis of the hinge connector 5 until it reaches the working position. This process fully utilizes the rotational freedom of the hinge and increases the extension distance of the baffle. Conversely, when the drive component 4 retracts, it drives the linkage assembly 3 to move in the opposite direction, causing the traction baffle 1 to rotate inward and downward and retract, folding inward around the hinge connector 5, as shown. Figure 5 As shown, the baffle retracts vertically and compactly at the front end of pedal 2, which not only saves space, but also, when the pedal is retracted and stored, the baffle retracts vertically and covers the adjacent pedal layers, playing a role in covering and sealing. This not only makes the step structure more complete, but also further enhances the overall sealing and safety of the pedal system.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
