[0036] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-6 The first aspect of the present invention describes a chassis 100 for a vehicle 200.

[0037] As shown in Figure 1, the chassis 100 for a vehicle 200 according to the first aspect embodiment of the present invention includes a frame 1, a first air reservoir 2 and at least one second air reservoir 3.

[0038] Specifically, the frame 1 along the first direction (e.g.) Figure 1 Extending in the front-rear direction (as shown), the first air tank 2 is located at the rear of the frame 1, and the first air tank 2 is adapted to be connected to the bottom of the battery box 201 of the vehicle 200. The second air tank 3 is connected to the frame 1, and the second air tank 3 and the first air tank 2 are arranged at intervals along a first direction, and the second air tank 3 and the frame 1 are arranged along a second direction (as shown). Figure 1 The first direction is perpendicular to the second direction (shown as up and down).

[0039] For example, in example 1, the first air tank 2 and the second air tank 3 are both located on the lower side of the frame 1. The first air tank 2 and the second air tank 3 are spaced apart in the front-rear direction. The first air tank 2 is located at the rear end of the frame 1, and the second air tank 3 is located in the middle of the frame 1.

[0040] This arrangement, placing the first air reservoir 2 and the second air reservoir 3 on the underside of the frame 1, avoids them occupying space on the left and right sides of the frame 1. This facilitates the installation of other components (such as fuel tanks) on the left and right sides of the frame 1, meeting the installation requirements and improving the usability of the chassis 100. Furthermore, the first air reservoir 2 and the second air reservoir 3 are spaced apart along the front-rear direction, facilitating connection with corresponding actuators (such as brake circuit actuators) based on their function. For example, when the first air reservoir 2 is a parking circuit air reservoir, it allows for easy connection with the vehicle 200's parking circuit actuator, improving response time. This also optimizes the layout of the first air reservoir 2 and the second air reservoir 3, avoiding heat sources and facilitating use. Additionally, the space on the underside of the frame 1 is fully utilized to accommodate the first air reservoir 2 and the second air reservoir 3, thus meeting the volume requirements of the first air reservoir 2 and the second air reservoir 3 within the vehicle 200.

[0041] According to the chassis 100 of the present invention for a vehicle 200, the first air reservoir 2 and the second air reservoir 3 are disposed on the bottom side of the frame 1, which facilitates the installation of other components on the left and right sides of the frame 1 to meet the installation and arrangement requirements on the frame 1, thereby improving the performance of the chassis 100. In addition, it facilitates the connection between the first air reservoir 2 and the second air reservoir 3 and the corresponding actuators, shortening the response time.

[0042] According to some embodiments of this utility model, refer to Figure 1 , Figure 2 and Figure 6 The first gas cylinder 2 is provided with at least one first connecting component 4. The first connecting component 4 includes a first connector 41. The first connector 41 includes a connecting section 411 and a fixing section 412. The connecting section 411 is in contact with the outer peripheral surface of the first gas cylinder 2. One side of the fixing section 412 is connected to the connecting section 411. The other side of the fixing section 412 extends away from the first gas cylinder 2. At least one first fixing hole 4112 is formed on the fixing section 412.

[0043] For example, in Figure 1 , Figure 2 and Figure 6In the example, the first connector 41 is disposed on the outer periphery of the first air cylinder 2, and the shape of the connecting section 411 is adapted to the shape of the first air cylinder 2. The lower side of the fixing section 412 is connected to the upper side of the connecting section 411, and the upper side of the fixing section 412 extends in an upward direction. The first connector 41 is connected to the first air cylinder 2, and the first air cylinder 2 can be connected to the battery box 201 through the first connector 41 of the first connecting assembly 4. This arrangement facilitates the connection between the first air cylinder 2 and the battery box 201 through the first connector 41, making the installation of the first air cylinder 2 and the battery box 201 easier and improving installation efficiency. In addition, the fit between the connecting section 411 and the outer periphery of the first air cylinder 2 also improves the stability of the fit between the first connector 41 and the first air cylinder 2, thereby improving the installation stability of the first air cylinder 2. Furthermore, the first connector 41 has a simple structure and is easy to form and process, thereby improving the production efficiency of the first connector 41.

[0044] Furthermore, referring to Figure 6 The first connecting assembly 4 also includes a first clamp 42, which is sleeved on the first gas storage cylinder 2, and the connecting section 411 is connected to the first gas storage cylinder 2 through the first clamp 42. For example, in Figure 6 In the example, the first clamp 42 is fitted around the outer periphery of the first gas cylinder 2 and the side of the connecting section 411 away from the first gas cylinder 2. That is, the first clamp 42 fixes the connecting section 411 to the outer periphery of the first gas cylinder 2. This arrangement strengthens the connection strength and stability between the connecting section 411 and the first gas cylinder 2, preventing the connecting section 411 from detaching from the first gas cylinder 2, thereby improving the installation stability of the first connecting assembly 4 and the first gas cylinder 2, and further enhancing the installation stability of the first gas cylinder 2. Multiple first clamps 42 can be provided; in this description, "multiple" means two or more. For example, two first clamps 42 can be provided, with each clamp 42 positioned at the left and right ends of the connecting section 411, respectively, connecting both ends of the connecting section 411 to the first gas cylinder 2, further improving connection stability. However, this is not the only possibility. It should be noted that the number and arrangement of the first clamps 42 can be specifically set according to actual usage to meet actual needs.

[0045] According to some embodiments of this utility model, refer to Figure 6 The length direction of connecting segment 411 (e.g.) Figure 6 Limiting structures 4111 are provided at both ends (shown in the left and right directions) to restrict the movement of the first hoop 42 in the third direction. For example, in Figure 6In the example, two limiting structures 4111 are provided, located at the left and right ends of the connecting section 411 respectively. The limiting structures 4111 are located on the side of the first hoop 42 away from the center of the connecting section 411. One end of the limiting structure 4111 is connected to the connecting section 411, and the other end extends away from the first gas storage cylinder 2. This arrangement limits the first hoop 42, preventing it from detaching from the connecting section 411 and improving the installation stability of the first hoop 42, thereby improving the installation stability of the first connecting assembly 4 and the first gas storage cylinder 2. However, this is not a limitation; multiple limiting structures 4111 can be provided on the connecting section 411, for example, four limiting structures 4111, located at the corners of the connecting section 411. It should be noted that the number and arrangement of the limiting structures 4111 can be specifically set according to actual usage to meet actual needs.

[0046] Optionally, refer to Figure 6 The length of the connecting segment 411 is greater than the length of the fixed segment 412, and the first hoop 42 and the fixed segment 412 are arranged along a third direction. For example, in Figure 6 In the example, along the left-right direction, the length of the connecting segment 411 is greater than the length of the fixed segment 412, and the first hoop 42 is located to the left or right of the fixed segment 412. This arrangement facilitates the installation of the first connector 41 and the first hoop 42, improving the installation efficiency. Furthermore, the fixed segment 412 also limits the movement of the first hoop 42 towards the center of the connecting segment 411, improving the installation stability of the first hoop 42. Moreover, the limiting structure 4111 cooperates with the fixed segment 412 to limit the first hoop 42 from both the left and right sides, further improving the installation stability of the first hoop 42 and the first connector 41.

[0047] According to some embodiments of this utility model, refer to Figure 2 and Figure 6 There are multiple first connecting components 4, and these multiple first connecting components 4 are arranged at intervals along the circumference of the first gas storage cylinder 2. For example, in Figure 2 and Figure 6 In the example, two first connectors 41 are provided, and the two first connecting components 4 are arranged at intervals along the circumference of the first air tank 2, and the two first connecting components 4 are symmetrically arranged along the central axis of the first air tank 2. This arrangement not only strengthens the connection between the first air tank 2 and the battery box 201, but also improves the installation stability of the first air tank 2, thereby improving the operational stability of the first air tank 2. Furthermore, a single first clamp 42 can simultaneously fix two first connectors 41 to the first air tank 2, thereby improving installation efficiency.

[0048] According to some embodiments of this utility model, refer toFigure 1 , Figure 3 and Figure 5 The second air reservoir 3 is provided with a second connecting assembly 5, which includes a second connecting member 51 and a second clamp 52. The second connecting member 51 includes a connecting part 511 and a fixing part 512. The connecting part 511 is connected to the second air reservoir 3, and the shape of the connecting part 511 is adapted to the shape of the outer peripheral surface of the second air reservoir 3. A part of the fixing part 512 overlaps with the connecting part 511, and the shape of a part of the fixing part 512 is adapted to the shape of the connecting part 511. The other part of the fixing part 512 is connected to the side of the frame 1. The second clamp 52 is sleeved on the second air reservoir 3, and the connecting part 511 is connected to the second air reservoir 3 through the second clamp 52.

[0049] For example, in Figure 1 , Figure 3 and Figure 5 In the example, the second connector 51 is disposed on the outer periphery of the second air reservoir 3. Along the vertical direction, the lower part (i.e., one portion) of the fixing part 512 overlaps with the connecting part 511. The shape of the lower part of the fixing part 512 matches the shape of the connecting part 511. The upper part (i.e., the other portion) of the fixing part 512 is connected to the side of the frame 1. The second band 52 is fitted around the outer periphery of the second air reservoir 3 and the side of the connecting part 511 away from the second air reservoir 3. In other words, the second band 52 connects the connecting part 511 to the second air reservoir 3.

[0050] This configuration, through the second clamp 52, strengthens the connection strength and stability between the connecting part 511 and the second air cylinder 3, preventing the connecting part 511 from detaching from the second air cylinder 3. This improves the installation stability of the second connecting assembly 5 and the second air cylinder 3, further enhancing the installation stability of the second air cylinder 3. Furthermore, the aforementioned portion of the fixing part 512 overlaps with the connecting part 511, improving the supporting effect of the second connecting part 51 on the second air cylinder 3 and preventing the second air cylinder 3 from shifting downwards after prolonged use, thus further improving the operational stability of the second air cylinder 3. Multiple second clamps 52 can be provided; for example, two second clamps 52 can be provided, with each clamp positioned at the front and rear ends of the connecting section 411, i.e., the two clamps 52 are positioned on the front and rear sides of the fixing part 512, connecting both ends of the connecting part 511 to the second air cylinder 3, further improving connection stability. However, this is not the only possibility. It should be noted that the number and arrangement of the second clamps 52 can be specifically configured according to actual usage conditions to meet specific needs.

[0051] Optionally, refer to Figure 3 and Figure 5 The length direction of the connecting part 511 (e.g.) Figure 5Limiting members 5111 are also provided at both ends of the second hoop 52 (in the front-back direction) to restrict movement along the first direction (i.e., the first direction). Weight-reducing holes 5112 are formed on the other part of the fixing portion 512. For example, in... Figure 3 and Figure 5 In the example, four limiting members 5111 are provided, with four on each of the left and right ends of the connecting portion 511. The limiting members 5111 are located on the side of the second hoop 52 away from the center of the connecting section 411, that is, at the corners of the connecting portion 511. One end of the limiting member 5111 is connected to the connecting portion 511, and the other end of the limiting member 5111 extends away from the second air tank 3. This configuration limits the second hoop 52, preventing it from detaching from the connecting portion 511, improving the installation stability of the second hoop 52, and thus improving the installation stability of the second connecting assembly 5 and the second air tank 3. Furthermore, the weight-reducing holes 5112 reduce the weight of the second connecting assembly 5 to meet the requirements of lightweight design. The upper part of the fixing portion 512 can be connected to the frame 1 with fasteners 2023 (e.g., bolts). However, this is not the only limitation. It should be noted that the number and arrangement of the limiting components 5111 can be set according to the actual usage to meet the actual needs.

[0052] According to some embodiments of this utility model, refer to Figure 1 There are multiple second gas storage cylinders 3, and the multiple second gas storage cylinders 3 are arranged along a third direction (e.g., Figure 1 The left and right directions are arranged alternately, and the third direction, the first direction, and the second direction are orthogonal. For example, in Figure 1 In the example, there are two second air reservoirs 3, arranged in a left-right direction. This arrangement allows for flexible use of multiple second air reservoirs 3 according to different operating conditions of the vehicle 200, thus meeting the needs of the vehicle 200 and improving the performance of the chassis 100. However, this is not the only limitation. It should be noted that the number and arrangement of the second air reservoirs 3 can be specifically set according to actual usage conditions to meet specific needs.

[0053] Optionally, refer to Figure 1 and Figure 4The chassis 100 also includes a third air reservoir 6 and a third connecting assembly 7. The third air reservoir 6 is located at the rear of the frame 1, positioned on the side of the first air reservoir 2 away from the second air reservoir 3. The third connecting assembly 7 includes at least one third connector 71 and a third band 72. The shape of the lower side of the third connector 71 is adapted to the shape of the outer circumference of the third air reservoir 6, and the upper end of the third connector 71 is connected to the frame 1. A mating groove 711 is formed at the lower end of the third connector 71. The third band 72 is fitted around the outer circumference of the third air reservoir 6, with a portion of the third band 72 fitting into the mating groove 711, connecting the third connector 71 to the third air reservoir 6. This configuration strengthens the connection between the third air reservoir 6 and the frame 1, thereby improving the operational stability of the third air reservoir 6 and enabling its long-term normal operation. Multiple third connecting assemblies 7 are provided, such as... Figure 4 There are two third connecting components 7. The two third connecting components 7 are arranged at intervals along the length direction (i.e., left and right direction) of the third air tank 6, which not only strengthens the connection strength between the third air tank 6 and the frame 1, but also improves the stability of the third air tank 6 during use.

[0054] In vehicle 200, the first air reservoir 2 can be a parking circuit air reservoir with a volume of 10L, and a second air reservoir 3 (such as...) Figure 1 The second air reservoir 3 on the left side below the center frame 1 can be a 30L forward travel circuit air reservoir. Another air reservoir (such as...) Figure 1 The second air tank 3) on the right side below the center frame 1 can be an auxiliary circuit air tank with a volume of 20L, and the third air tank 6 can be a rear travel circuit air tank with a volume of 50L, supplying air to each circuit to meet braking function and efficiency. However, it is not limited to this and can be set according to the actual use.

[0055] According to a second aspect embodiment of the present utility model, the vehicle 200, with reference to... Figure 1 This includes the chassis 100 for a vehicle 200 according to the first aspect embodiment of the present invention described above.

[0056] According to the present invention, the vehicle 200, by adopting the aforementioned chassis 100, facilitates the arrangement of other components of the vehicle 200 (such as a fuel engine) and meets the layout requirements of the vehicle 200.

[0057] According to some embodiments of this utility model, refer to Figure 1 , Figure 6 and Figure 7The vehicle 200 also includes a battery box 201, which is located at the rear of the frame 1 of the chassis 100. The bottom of the battery box 201 is provided with a connecting structure 202, which includes a connecting structure body 2021, a fixing member 2022 and a fastener 2023. The connecting structure body 2021 is connected to the bottom of the battery box 201. At least one second fixing hole 2021a is formed on the connecting structure body 2021. The fixing member 2022 is connected to the connecting structure body 2021. The fastener 2023 passes through the first fixing hole 4112 and the second fixing hole 2021a of the chassis 100 in sequence and is connected to the fixing member 2022.

[0058] For example, in Figure 2 , Figure 6 and Figure 7 In the example, the connecting structure 202 is connected to the lower side of the battery box 201, and the connecting structure body 2021 is connected to the lower side of the battery box 201. The connecting structure body 2021 is roughly inverted "U" shaped. The connecting structure body 2021 and the battery box 201 can be connected by welding, but are not limited to this method. The front and rear ends of the connecting structure body 2021 extend downwards, and the second fixing hole 2021a is formed on the downwardly extending end of the connecting structure body 2021. The fixing member 2022 is connected to the aforementioned downwardly extending end of the connecting structure body 2021, and the fixing member 2022 and the second fixing hole 2021a are opposite each other in the front-rear direction. The aforementioned downwardly extending end of the connecting structure body 2021 is opposite to the fixing section 412 in the front-rear direction, that is, the first fixing hole 4112, the second fixing hole 2021a, and the fixing member 2022 are opposite each other in the front-rear direction.

[0059] With this configuration, fasteners 2023 pass sequentially through the first fixing hole 4112 and the second fixing hole 2021a, engaging with the fixing member 2022 to connect the first connecting member 41 to the main body of the connecting structure 202. This connects the first air cylinder 2 to the battery box 201, securing the first air cylinder 2 and facilitating its use. Furthermore, the connecting structure 202 is simple, facilitating connection between the connecting structure 202 and the first connecting member 41, thus improving installation efficiency. Multiple first fixing holes 4112, second fixing holes 2021a, fixing members 2022, and fasteners 2023 are provided. For example, there are four first fixing holes 4112, four second fixing holes 2021a, four fixing members 2022, and four fasteners 2023, which are assembled one-to-one. The downward-extending end of the front end of the connecting structure body 2021 is connected to one first connecting member 41, and the downward-extending end of the rear end of the connecting structure body 2021 is connected to another first connecting member 41. Through multiple first connecting members 41, the connection stability between the connecting structure 202 and the first gas storage cylinder 2 is further enhanced. However, this is not the only limitation. It should be noted that the number and arrangement of the first fixing holes 4112, fasteners 2023, second fixing holes 2021a, and fixing members 2022 can be specifically set according to actual usage conditions to meet actual needs.
