[0041] Reference Figures 1 to 4 , Figure 1 shows a part of the components of the vehicle according to the embodiments of the present disclosure. In an exemplary embodiment, the lower cab guard assembly 100 is used to be installed in the cab of the vehicle 1000. The vehicle 1000 provided by the embodiments of the present disclosure includes an instrument panel (not shown), a lower cab guard assembly 100, a steering column assembly 200, a carpet 300, and a pedal 400.

[0042] The steering column assembly 200 can be connected to the instrument panel. Specifically, the steering column assembly 200 can include a steering shaft 201 connected to the instrument panel, an intermediate steering column shaft 202 drivingly connected to the steering shaft 201 and extending out of the instrument panel, and a cross joint 203 drivingly connected to the intermediate steering column shaft 202. The intermediate steering column shaft 202 or the cross joint 203 can extend under the carpet 300.

[0043] Combined Figures 4 to 6 , the pedal 400 can include a pedal lever 401 and a foot pedal 402. The pedal 400 extends downward from the instrument panel, and the pedal lever 401 can swing. The vehicle 1000 or the pedal 400 further includes a fixed seat 403, and the pedal lever 401 can be rotatably connected to the fixed seat 403.

[0044] As Figure 1 shown, the carpet 300 has notches at the steering column assembly 200 and the pedal 400.

[0045] The under-cab guard assembly 100 provided by the embodiments of the present disclosure includes a mounting plate 1, a profiling structure 2, an extension plate 3, and a limiting block 4.

[0046] The mounting plate 1 is used for mounting to the instrument panel. Exemplarily, the mounting plate 1 extends substantially along the XY plane. The mounting plate 1 is generally located on the lower side of the instrument panel.

[0047] The extension plate 3 is connected to the mounting plate 1. The extension plate 3 can be connected to the front end of the mounting plate 1, and the extension plate 3 can be indirectly connected to the mounting plate 1. Exemplarily, referring to Figure 1 and Figure 2 , the extension plate 3 corresponds to the left part of the mounting plate 1.

[0048] The profiling structure 2 is connected to the mounting plate 1. The profiling structure 2 is juxtaposed with the extension plate 3, and the two can be directly or indirectly connected along the Y-axis direction. Exemplarily, the profiling structure 2 corresponds to the right part of the mounting plate 1. The intermediate steering column shaft 202 will be in front of the driver, and the profiling structure 2 is used to cover the intermediate steering column shaft 202 extending from the instrument panel, that is, to separate the intermediate steering column shaft 202 from the driver along the X-axis direction.

[0049] Referring to Figure 3 and Figure 6 , the profiling structure 2 is spaced from the intermediate steering column shaft 202 to ensure the rotational space envelope requirements of the intermediate steering column shaft 202. The gap size formed between the profiling structure 2 and the intermediate steering column shaft 202 can be substantially uniform. Referring to Figure 1 , Figure 2 and Figure 4, one side of the profiling structure 2's back extension plate 3 is an envelope edge 23 that can avoid the pedal 400. The pedal 400 can swing, so the envelope edge 23 maintains a distance from the pedal 400 in any posture, and the minimum distance between each part of the envelope edge 23 and the pedal 400 can be basically uniform.

[0050] Combined with Figures 3 to 8 , the limit block 4 is connected to the extension plate 3, and the limit block 4 is used to install the carpet 300. The extension plate 3 is used to be laminated on the carpet 300. Exemplarily, along the Z-axis direction, the extension plate 3 presses on the carpet 300. A part of the profiling structure 2 can also press on the carpet 300.

[0051] The mounting plate 1 of the cab lower guard plate assembly 100 cooperates with the limit block 4, ensuring that the cab lower guard plate assembly 100 is installed in place and can play a role in fixing the carpet 300. The cab lower guard plate assembly 100 cooperates with surrounding components to shield the intermediate shaft 202 of the steering column, preventing metal parts from leaking out. It can separate the driver from the intermediate shaft 202 of the steering column, effectively avoiding the direct contact between the intermediate shaft 202 of the steering column and the humid environment in the cab, which helps to block the humid gas brought by the driver; it can connect the instrument panel and the carpet 300. The cab lower guard plate assembly 100 can also ensure the safe and reliable movement of the intermediate shaft 202 of the steering column and the pedal 400 by setting the profiling structure 2.

[0052] The cab lower guard plate assembly 100 of the present disclosure embodiment meets the layout space of the intermediate shaft 202 of the steering column and the ergonomic foot space, and plays a role in delaying the rust of the intermediate shaft 202 of the steering column.

[0053] In some embodiments, the cab lower guard plate assembly 100 further includes a tongue-shaped plate 5. The tongue-shaped plate 5 is connected to the profiling structure 2. The tongue-shaped plate 5 is located below the profiling structure 2 along the Z-axis direction and can also be partially connected to the extension plate 3. The side of the tongue-shaped plate 5 facing the extension plate 3, i.e., the mating edge 51, is laminated on the carpet 300, and the side of the tongue-shaped plate 5 facing away from the extension plate 3, i.e., the avoidance edge 52, is spaced from the carpet 300. The avoidance edge 52 is also spaced from the pedal 400. The avoidance edge 52 is smoothly and continuously connected to the envelope edge 23 and can be integrated into one body, which can avoid the pedal 400 and form a basically uniform minimum gap. The cab lower guard plate assembly 100 can be fully combined with other components in the installation environment, and the tongue-shaped plate 5 is beneficial to maximizing the shielding of the intermediate shaft 202 of the steering column.

[0054] Exemplarily, along the direction away from the profiling structure 2, the dimension of each part of the tongue-shaped plate 5 in the Y-axis direction becomes smaller and smaller. The lower end of the tongue-shaped plate 5 can be a rounded sharp angle shape.

[0055] Refer to Figure 5 and Figure 6 , Figure 5 and Figure 6Both show two outlines of a pedal 400 at the raised position and the bottom dead center position.

[0056] In some embodiments, the tongue-shaped plate 5 has a stepped structure and is spaced from the pedal 400. The tongue-shaped plate 5 can ensure that the working stroke of the pedal 400 is not affected. Exemplarily, the tongue-shaped plate 5 includes a first step 53 and a second step 54. The first step 53 can be connected to the profiling structure 2, and the second step 54 is connected to the first step 53. Along the X-axis direction, the second step 54 is more forward than the first step 53, that is, farther from the foot pedal 402.

[0057] In some embodiments, the distance between the profiling structure 2 and the pedal 400 is greater than 10 mm, which helps to use the pedal 400 safely and reliably. Exemplarily, the distances between the enveloping edge 23 and the avoiding edge 52 and the pedal rod 401 of the pedal 400 are greater than 10 mm. Exemplarily, each distance is 15 mm to 20 mm, such as 17 mm, ensuring that the gap between the pedal 400 and its surrounding parts is sufficient and maintaining the effect of shielding the intermediate shaft 202 of the steering column.

[0058] The distance between the profiling structure 2 and the intermediate shaft 202 of the steering column is greater than 12 mm, ensuring the movement of the intermediate shaft 202 of the steering column. Exemplarily, this distance can be less than or equal to 20 mm, and the profiling structure 2 occupies a small space. The specific dimensions of the profiling structure 2 can be adjusted according to the setting requirements of the tongue-shaped plate 5 it is connected to; the design of the tongue-shaped plate 5 is also affected by the boundary conditions of the profiling structure 2.

[0059] Combined Figure 5 As shown, the pedal 400 is in the raised position. When the pedal 400 is at the bottom dead center position, it can be called the pedal 400' at the bottom dead center position and has the contour pose as shown in the figure.

[0060] The gap h between the lower cab guard assembly 100 on the pedal 400' at the bottom dead center position is greater than 50 mm, which can not affect the foot space. Without changing the heel point, the lower cab guard assembly 100 does not hinder the moving space of the toe. Exemplarily, the gap h on the pedal 400' at the bottom dead center position is 54 mm. Specifically, in the lower cab guard assembly 100, the structure located directly above the pedal 400' at the bottom dead center position along the Z-axis direction can be the first step 53 of the tongue-shaped plate 5. The stepped tongue-shaped plate 5 is beneficial to ensure that the foot space is large enough. Exemplarily, there is a gap between the second step 54 of the tongue-shaped plate 5 and the foot pedal 402 of the pedal 400' at the bottom dead center position, and the dimension of this gap along the X-axis direction can be greater than the distance between the enveloping edge 23 and the pedal rod 401.

[0061] Exemplarily, the profiling structure 2 includes a base plate 21 and a profiling groove 22. The distance between the profiling groove 22 and the intermediate shaft 202 of the steering column is greater than 12 mm, and the distances at various positions can be substantially uniform, ensuring the movement envelope of the intermediate shaft 202 of the steering column. The envelope edge 23 can be a part of the base plate 21 or can be parts of the base plate 21 and the profiling groove 22 respectively. The base plate 21 is used to ensure the connection of the profiling groove 22 to the remaining structures in the lower cab guard assembly 100. The base plate 21 can be substantially flat and can be connected to the extension plate 3. In some embodiments, it can be considered that the extension plate 3 is connected to the mounting plate 1 through the base plate 21.

[0062] Reference Figure 5 , in some embodiments, the deflection degree of the extension plate 3 relative to the mounting plate 1 is greater than the deflection degree of the profiling structure 2 relative to the mounting plate 1. The tongue-shaped plate 5 is lower than the extension plate 3, which can ensure the shielding of the intermediate shaft 202 of the steering column and can be well matched with the installed carpet 300. The profiling structure 2 can extend approximately along a 45° angle in the XZ plane relative to the X-axis direction, and the extension plate 3 can extend approximately along the Z-axis direction. Exemplarily, the extension plate 3 is deflected in the XY plane relative to the base plate 21.

[0063] In some embodiments, the limiting block 4 is located in front of the extension plate 3 and is higher than the lower edge of the extension plate 3; the front end of the limiting block 4 is upturned, ensuring the overlap of the carpet 300 and the extension plate 3; which is beneficial to the assembly of the carpet 300.

[0064] The space enclosed by the mounting plate 1, the profiling structure 2 and the carpet 300 can accommodate the driver's feet.

[0065] Combined Figure 7 and Figure 8 , in some embodiments, the limiting block 4 includes a trough-shaped main body 40 and an I-shaped strengthening part 42. The folded edge 41 of the trough-shaped main body 40 faces upward, and the front folded part 411 of the folded edge 41 is upturned, and the front folded part 411 is thicker than the rear folded part 412 of the folded edge 41; the I-shaped strengthening part 42 is located inside the trough-shaped main body 40 and is at least partially located at the front folded part 411. The structure of the limiting block 4 is beneficial to manufacturing and ensures the strength of the limiting block 4 itself and its connection strength with the extension plate 3. The I-shaped strengthening part 42 can extend approximately along the Z-axis direction and has an I-shaped cross-section.

[0066] The tongue-shaped plate 5, the limiting block 4, the extension plate 3, the profiling structure 2 and the mounting plate 1 can be an integral structure.

[0067] Reference Figures 1 to 3, in some embodiments, the mounting plate 1 is provided with an air-conditioning vent 11, an on-vehicle diagnostic system maintenance plug 12, and a footlight 13, enriching the functions of the lower cab guard assembly. There can be multiple air-conditioning vents 11, and their corresponding profiling structures 2, that is, corresponding to the pedal 400, can blow air on the driver's feet, providing a comfortable driving experience. The on-vehicle diagnostic system maintenance plug 12 corresponds to the extension plate 3, effectively utilizing the space and ensuring the maintenance of the instrument panel.

[0068] Exemplarily, along the X-axis direction, the air-conditioning vent 11 is more forward, while the footlight 13 is more backward, which can adjust the air flow and ensure the lighting range.

[0069] In some embodiments, the mounting plate 1 is further provided with a flat card 14 for plugging into the instrument panel, a buckle 15 for clamping to the instrument panel, a round buckle 16 for connecting the air-conditioning evaporator, and a card connection point 17 for connecting the air-conditioning ventilation pipe 501. The mounting plate 1 and the lower cab guard assembly 100 are easy to install and the installation is reliable, and can effectively cooperate with other components to ensure the installation space and the driving space.

[0070] The flat card 14 can be located at the rear edge of the mounting plate 1, and two can be arranged at intervals along the Y-axis direction.

[0071] The buckle 15 can be located at the rear edge of the mounting plate 1, and two can be arranged at intervals along the Y-axis direction, and can be alternately arranged with the flat card 14.

[0072] The round buckle 16 can be at the right front corner of the mounting plate 1.

[0073] Combined Figure 1 and Figure 2 , the card connection point 17 can have three or other numbers. The three card connection points 17 can be arranged in a triangle around the air-conditioning vent 11 and are respectively connected to the air-conditioning ventilation pipe 501.

[0074] The vehicle 1000 provided by the embodiments of the present disclosure can separate the driver from the intermediate shaft 202 of the steering column by including the aforementioned lower cab guard assembly 100. The vehicle 1000 of the embodiments of the present disclosure can be used normally and has a better rust prevention effect after long-term use.

[0075] Exemplarily, the vehicle 1000 further includes an air-conditioning system 500. The air-conditioning system 500 can include an air-conditioning evaporator and an air-conditioning ventilation pipe 501. The cab of the vehicle 1000 can be on the left or on the right.
