Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile chassis, in particular to an automobile wire-controlled chassis. Background Art
[0002] A drive-by-wire chassis is a chassis system that utilizes an electronic control system instead of traditional mechanical connections. Unlike traditional chassis systems, which operate the accelerator, brakes, and steering wheel directly through physical connections (such as cables and levers), a drive-by-wire chassis system uses electronic sensors and cables to transmit the driver's control signals. However, this system is more common in new energy vehicles. In existing technology, the battery of a new energy vehicle is typically installed within the drive-by-wire chassis. However, to improve the chassis's protective performance, some drive-by-wire chassis often tightly encase the battery. This tight enclosure restricts heat exchange between the battery and the surrounding air, resulting in poor heat dissipation. Utility Model Content
[0003] The purpose of the utility model is to address the problem that the batteries of new energy vehicles are usually installed in the vehicle chassis, but in order to improve the protection performance of the chassis, some automobile wire-controlled chassis usually wrap the batteries tightly, and the tight wrapping limits the heat exchange between the battery and the surrounding air, resulting in poor heat dissipation effect.

[0005] Optionally, the heat dissipation mechanism includes a plurality of linearly arranged air inlet holes opened on the cover, a plurality of linearly arranged air ducts corresponding to the air inlet holes are fixedly connected to the lower surface of the cover, an end of the air duct away from the air inlet holes is fixedly connected to an air guide cover for gathering air, and a plurality of air holes fixedly connected to the air duct are opened on the air guide cover.

[0007] Optionally, the windshield block is provided with a pair of inclined surfaces that allow airflow to flow smoothly.

[0012] In summary, this application includes at least one of the following beneficial technical effects of a wire-controlled chassis for an automobile:
[0013] This utility model utilizes a combination of an anti-collision frame, a cover, a heat dissipation mechanism, and a resistance reduction mechanism to not only prevent sharp objects from puncturing the battery within the vehicle's drive-by-wire chassis, thus avoiding the risk of battery short circuits, leakage, or fire, thereby improving the safety of the entire vehicle, but also maintains good heat dissipation within the vehicle's drive-by-wire chassis during operation, reducing the acceleration of chemical reactions caused by overheating and thus extending the battery's service life.

[0020] like Figure 1-Figure 5As shown, the utility model proposes a car wire-controlled chassis, including a wire-controlled chassis body 1 and a mounting groove 11 provided at the bottom of the wire-controlled chassis body 1, a filter 13 is provided inside the mounting groove 11 to prevent dust from entering, a battery 12 is provided inside the mounting groove 11, and further includes: a cover 2 installed on the lower surface of the wire-controlled chassis body 1, an air outlet 24 is provided at one end of the cover 2 away from the air inlet 23 to allow air to circulate inside the cover 2, an anti-collision frame 21 is fixedly connected to the lower surface of the cover 2, and a plurality of staggered reinforcement rods 22 are provided inside the anti-collision frame 21. The staggered reinforcement rods 22 form a more robust mesh structure. This design can more effectively disperse and withstand impacts and loads from different directions, thereby improving the overall structural strength of the chassis. At the same time, the staggered configuration of the reinforcement rods 22 forms a multi-layer protection, which can provide additional resistance when sharp objects contact the chassis, thereby reducing the risk of sharp objects piercing the car wire-controlled chassis. Furthermore, the staggered reinforcement bars 22 help evenly distribute stress on the vehicle's drive-by-wire chassis, avoiding localized stress concentrations and thus reducing the likelihood of material fatigue and damage. Finally, in the event of a collision or external impact, the reinforcement bars 22 effectively absorb and disperse the impact force, reducing direct impact on the battery 12 and other key components, and enhancing vehicle safety. A heat dissipation mechanism, mounted on the cover 2, removes heat generated by the battery 12 through airflow. A drag reduction mechanism, removably mounted on the heat dissipation mechanism, reduces air turbulence and friction.
[0021] Furthermore, the heat dissipation mechanism includes a plurality of linearly arranged air inlet holes 23 provided on the cover 2, and a plurality of linearly arranged air ducts 4 corresponding to the air inlet holes 23 are fixedly connected to the lower surface of the cover 2, and one end of the air duct 4 away from the air inlet holes 23 is fixedly connected to an air guide cover 3 for gathering air, and both ends of the air guide cover 3 are also connected to a second connecting block 32 corresponding to the third connecting block 52 and spirally connected to the mounting bolts 53, and a plurality of air ducts 33 fixedly connected to the air duct 4 are provided on the air guide cover 3.
[0022] Furthermore, the resistance reduction mechanism includes a windshield block 5 movably connected to the wind guide cover 3. The windshield block 5 is provided with a pair of inclined surfaces 51 that allow airflow to flow smoothly. The function of the inclined surfaces 51 is to streamline the windshield block 5 when installed on the open end of the wind guide cover 3, thereby reducing wind resistance when airflow passes through the windshield block 5. The windshield block 5 is fixedly connected to the two ends of the windshield block 5 with third connecting blocks 52, and the wind guide cover 3 is fixedly connected to the two ends of the first connecting block 31 corresponding to the third connecting block 52. Bolt holes 321 are provided in both the first connecting block 31 and the third connecting block 52. Mounting bolts 53 are screwed into the bolt holes 321. The mounting bolts 53 are used to allow the windshield block 5 to have two configurations on the wind guide cover 3: one configuration opens the heat dissipation mechanism, and the other closes the heat dissipation mechanism.
[0023] In this embodiment, when it is necessary to use the car wire control chassis, Figure 1 As shown, the battery 12 in the mounting slot 11 is completely enclosed by the anti-collision frame 21 and the reinforcement rod 22 at the bottom of the cover 2. When the wire-controlled chassis body 1 is in operation, the third connecting blocks 52 at both ends of the windshield block 5 are first clamped on the second connecting block 32 on the wind guide cover 3, and the mounting bolts 53 are installed on the third connecting blocks 52 and the second connecting blocks 32, so that the windshield block 5 can be firmly installed on the wind guide cover 3. When the wire-controlled chassis body 1 is in operation, airflow is generated. The airflow enters the air duct 4 and the air inlet 23 in sequence from the air duct 33 on the wind guide cover 3, and then all the flowing air enters the cover 2. The airflow then passes through the filter 13 in the mounting slot 11, driving the heat generated by the battery 12. Finally, the hot air flow is discharged from the air outlet 24 at the end of the cover 2 away from the wind guide cover 3, so that the heat generated by the battery 12 in the mounting slot 11 is continuously discharged, quickly and efficiently. When the heat dissipation mechanism needs to be closed, the windshield 5 only needs to be clamped onto the open end of the wind scoop 3, and the third connecting blocks 52 at both ends of the windshield 5 are aligned with the first connecting blocks 31 at both ends of the wind scoop 3. Finally, the mounting bolts 53 are passed through the third connecting blocks 52 and the first connecting blocks 31. The windshield 5 can completely block the airflow from entering the wind scoop 3. The streamlined design of the inclined surface 51 on the windshield 5 can reduce friction and separation in the airflow when it blows over the windshield 5, thereby reducing the overall wind resistance.
