[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] The following is for reference. Figures 1-7 Vehicle 1 according to an embodiment of the present utility model is described.

[0030] like Figures 1-4 As shown, the vehicle 1 according to an embodiment of the present invention includes: a frame 10, a cab floor, and a front suspension assembly 20. The frame 10 is the main structure of the vehicle 1, which mainly provides support and load-bearing capacity for the entire vehicle. The cab floor mainly serves a load-bearing function, supporting the occupants and facilities inside the cab. The front suspension assembly 20 mainly absorbs and isolates vibrations from the engine and chassis, improving the driving stability and ride comfort of the vehicle 1.

[0031] like Figures 2-4 As shown, the front suspension assembly 20 includes an upper bracket 200, a mounting base 201, and a pin 202. The upper bracket 200 is connected to the cab floor, the mounting base 201 is connected to the vehicle frame 10, the upper bracket 200 is rotatably mounted on the pin 202, the pin 202 is fixed to the mounting base 201, and the pin 202 is located below the upper wing surface 100 of the vehicle frame 10.

[0032] The upper bracket 200, the fixed seat 201, and the pin 202 are components of the front suspension assembly 20. The upper bracket 200 mainly serves a connecting and supporting function, the fixed seat 201 mainly serves a fixing and vibration damping function, and the pin 202 mainly serves a connecting function. The upper bracket 200 is connected to the cab floor, thereby connecting the front suspension assembly 20 to the cab floor. The fixed seat 201 is connected to the vehicle frame 10, and the front suspension assembly 20 is connected to the vehicle frame 10 through the fixed seat 201. The upper bracket 200 is rotatably mounted on the pin 202 and can rotate around the pin 202. The pin 202 is fixed to the fixed seat 201, and the pin 202 is fixedly connected to the fixed seat 201. That is to say, the upper bracket 200 can rotate relative to the fixed seat 201 through the pin 202, which facilitates the maintenance of vehicle 1. Moreover, the pin 202 is located below the upper wing surface 100 of the frame 10. The placement of the pin 202 below the upper wing surface 100 of the frame 10 can reduce the overall height dimension and the vehicle body tilt center, lower the vehicle body positioning, and change the two-step to a single-step, which is beneficial to improve the convenience of getting on and off the vehicle, human-machine efficiency, and ensure the convenience of maintenance. At the same time, it can reduce blind spots and improve driving safety. The upper bracket 200 can be connected to the cab floor by welding, and the fixed seat 201 can be connected to the frame by bolts.

[0033] Thus, the upper bracket 200 is connected to the cab floor, the fixed seat 201 is connected to the frame 10, the upper bracket 200 is rotatably mounted on the pin 202, the pin 202 is fixed to the fixed seat 201, and the pin 202 is located below the upper wing surface 100 of the frame. This can reduce the overall height dimension of the vehicle and the vehicle body rollover center, lower the vehicle body positioning, and change the two-step to a single-step, which is beneficial to improve the convenience of getting on and off the vehicle, human-machine efficiency and ensure the convenience of maintenance, while reducing blind spots and improving driving safety.

[0034] Specifically, such as Figures 2-4 As shown, the front suspension assembly 20 also includes a buffer 203, with a pin 202 fixed to the buffer 203, and the buffer 203 and the mounting base 201 are interference-fitted. The buffer 203 mainly serves a buffering function, reducing the direct rigid contact between the frame 10 and the front suspension assembly 20, and further enhancing the vibration damping effect of the front suspension assembly 20. The pin 202 is fixed to the buffer 203, and the buffer 202 and the mounting base 201 are fixedly arranged. The interference fit between the buffer 203 and the mounting base 201 provides good stability and sealing, and can also effectively transfer loads. In addition, it makes the front suspension assembly 20 more compact and reliable, which helps to improve the overall performance of the vehicle 1.

[0035] Among them, such as Figures 2-4 As shown, the buffer component 203 is a rubber structural component. Rubber structural components have advantages such as good elasticity and strong vibration resistance. By setting the buffer component 203 as a rubber structural component, the buffer component 203 is more in line with the actual working conditions and can play a role in vibration reduction. This can further enhance the vibration reduction effect of the front suspension assembly 20 and improve the driving stability and ride comfort of the vehicle 1.

[0036] In addition, such as Figures 2-4 As shown, the mounting base 201 is provided with multiple mounting portions 204, which are spaced apart. The mounting portions 204 mainly serve to install and fix the vehicle. The mounting portions 204 further strengthen the connection between the mounting base 201 and the frame 10, thus preventing instability in the installation of the front suspension assembly 20 and ensuring the stability and reliability of the front suspension assembly 20. This improves the driving stability and ride comfort of the vehicle 1. The spaced arrangement of the mounting portions 204 avoids interference between them and allows for a wider distribution of the mounting portions 204, which also strengthens the connection between the mounting base 201 and the frame 10 to a certain extent.

[0037] Of course, such as Figure 1 and Figures 5-7 As shown, vehicle 1 also includes a rear suspension assembly 30, which includes a locking assembly 300, a lower bracket 301, and an elastic member 302. The locking assembly 300 is connected to the cab floor, the lower bracket 301 is connected to the frame 10, and the elastic member 302 is connected between the locking assembly 300 and the lower bracket 301, and the elastic member 302 forms an angle with the vertical plane.

[0038] It should be noted that the rear suspension assembly 30 primarily absorbs and isolates vibrations from the engine and chassis, improving the vehicle's ride stability and comfort. The locking assembly 300, lower bracket 301, and elastic element 302 are components of the rear suspension assembly 30. The locking assembly 300 can fix or restrict certain movements, ensuring the rear suspension assembly 30 remains stable under specific conditions. The lower bracket 301 mainly serves a connecting and supporting function. The elastic element 302 absorbs and mitigates vibrations and impacts from the road surface, improving ride comfort. Additionally, it helps restore the position of the rear suspension assembly 30, allowing it to quickly recover from external forces. The locking assembly 300 is connected to the cab floor, thereby connecting the rear suspension assembly 30 to the cab floor. The lower bracket 301 is connected to the frame 10, and the rear suspension assembly 30 can be connected to the frame 10 via the lower bracket 301. An elastic element 302 is connected between the locking assembly 300 and the lower bracket 301, forming an angle with the vertical plane. This angle increases the lateral movement. The elastic element 302 can be a coil spring assembly.

[0039] Furthermore, such as 5- Figure 7 As shown, the angle between the elastic element 302 and the vertical plane is α, and the value of α ranges from 10° to 15°. The angle α between the elastic element 302 and the vertical plane needs to meet a certain range. Specifically, the angle α cannot be too small, i.e., less than 10°, as this would affect the height dimension of vehicle 1, hindering the reduction of the overall vehicle height dimension and body positioning. Simultaneously, the angle α cannot be too large, i.e., greater than 15°, as this would affect the suspension effect of the rear suspension assembly 30, impacting its damping function and consequently affecting the stability and ride comfort of vehicle 1. Therefore, the angle α between the elastic element 302 and the vertical plane should be set between 10° and 15°. At this range, the elastic element 302 can provide a relatively ideal damping effect, neither too stiff nor too soft, allowing the rear suspension assembly 30 to better disperse and absorb vibrations and impacts from the road surface.

[0040] In addition, such as 5- Figure 7As shown, the locking assembly 300 includes: an upper locking body bracket 303 and a hydraulic lock 304. The upper locking body bracket 303 is connected to the cab floor, and the elastic element 302 is connected to the hydraulic lock 304. The hydraulic lock 304 is connected to the upper locking body bracket 303. Specifically, the upper locking body bracket 303 is provided with a locking pin 305, and the hydraulic lock 304 is connected to the locking pin 305. The upper locking body bracket 303 and the hydraulic lock 304 are components of the locking assembly 300. The upper locking body bracket 303 mainly serves as a connector and support, while the hydraulic lock 304 uses the pressure of hydraulic oil to lock and unlock, fixing or restricting certain movements to ensure the stability of the rear suspension assembly 30 under specific conditions. The upper locking body bracket 303 is connected to the cab floor, thereby achieving the connection between the rear suspension assembly 30 and the cab floor. The elastic element 302 is connected to the hydraulic lock 304. The hydraulic lock 304 is connected to the pressure lock 304, and the elastic element 302 is connected to the hydraulic lock 304. The upper lock body bracket 303 can rotate relative to the lower bracket 301, which facilitates the maintenance of vehicle 1. The upper lock body bracket 303 is provided with a locking pin 305, which mainly plays a role in fixing and locking. The hydraulic lock 304 is connected to the locking pin 305. At this time, the locking assembly 300 can realize fast and reliable locking and unlocking functions, which can improve the driving performance and reliability of vehicle 1.

[0041] It should be noted that, as Figures 5-7 As shown, the locking assembly 300 also includes a bushing 306, which is sleeved on the outside of the locking pin 305. The bushing 306 is a component of the locking assembly 300. The bushing 306 primarily reduces wear, vibration, and noise. Sleeving the bushing 306 on the outside of the locking pin 305 allows for better connection between the hydraulic lock 304 and the locking pin 305, enabling the locking assembly 300 to achieve fast and reliable locking and unlocking functions, thus improving the driving performance and reliability of the vehicle 1. The bushing 306 can be a metal bushing with a rubber interlayer.

[0042] In addition, such as Figures 2-7 As shown, the upper bracket 200, the upper lock body bracket 303, and the lower bracket 301 are all welded structural components. Welded structural components are lightweight. By making the upper bracket 200, upper lock body bracket 303, and lower bracket 301 all welded structural components, a lightweight design of vehicle 1 can be achieved, which helps to reduce the overall weight of vehicle 1 and thus reduce the manufacturing cost of vehicle 1. Secondly, it can improve the maneuverability of vehicle 1. In addition, making the upper bracket 200, upper lock body bracket 303, and lower bracket 301 all welded structural components simplifies the manufacturing process of the upper bracket 200, upper lock body bracket 303, and lower bracket 301, making their production easier.
