Description

Technical Field

[0001] The present invention relates to the technical field of automobile chassis, and more specifically, to an adjustable chassis for new energy vehicles. Background Art

[0002] As a core element to improve the overall performance of vehicles, the importance of lightweight chassis components for new energy vehicles is self-evident. In this field, lightweight design is not only a symbol of pursuing the forefront of technology, but also a necessary way to achieve green travel and improve energy efficiency. Through sophisticated lightweight strategies, the overall weight of the vehicle can be significantly reduced. This measure directly affects the energy consumption and endurance performance of the vehicle. As revealed by the Ricardo Institute, every 100kg reduction in body weight can bring about a 10-11% increase in mileage, which undoubtedly adds a strong touch to the practicality and market competitiveness of new energy vehicles. Further, the introduction of lightweight floor also profoundly affects the handling and comfort of the vehicle. Lightweight design effectively reduces the unsprung mass of the vehicle, that is, the unsprung mass (such as wheels, suspension, etc.), which means that during driving, the wheels are more sensitive to uneven road surfaces, and the energy required to drive the wheels is greatly reduced.

[0003] However, the current new energy vehicle field is still facing challenges such as complex structures and numerous load-bearing facilities. Although these additional configurations enrich the functionality of the vehicle, they also invisibly increase the weight and driving burden of the vehicle, accelerating the wear and consumption of vehicle components. At the same time, as an important supporting structure of the vehicle, the chassis's bottom protection and durability cannot be ignored. When passing through a section of the road with potholes, it is not only easy to cause bumps and damage to the chassis, but also easy to accumulate liquid in the potholes, thereby corroding the chassis of the car and even penetrating into the battery box to cause a short circuit. In view of this, we propose an adjustable chassis for new energy vehicles. Summary of the invention

[0004] The purpose of the present invention is to provide an adjustable chassis for new energy vehicles to solve the technical problem that the existing automobile chassis components have relatively weak protective functions. If a large number of protective structures are used, it is easy to increase the weight of the bottom plate, making it difficult to reduce the weight of the chassis while ensuring the safety of the chassis.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By designing a pressure component, a buffer component, a transmission component and a control component, the device can play the following roles when the vehicle is driving: due to its own shape, the pressure component will deform due to the pressure generated by the contact with the airflow during the vehicle driving. When the vehicle encounters a potholed road section, on the one hand, under the combined action of manual control and the road conditions of the potholed road section, the vehicle speed will decrease; on the other hand, when the chassis component is about to collide with the ground, the anti-collision component will contact the ground first. The device has dual protection and heat dissipation functions. First, during the vehicle driving process, it can use the generated airflow for heat dissipation to ensure that the inside of the chassis component is always in a low temperature state during use, avoiding damage to the battery due to being in a high temperature environment for a long time. Second, when encountering a potholed road section, the device can not only effectively protect the chassis component with a relatively light weight, but also quickly close the ventilation slot to prevent the liquid in the potholed road section from entering the battery interior, further enhancing the protection effect of the device on the battery and improving the safety during use.

[0026] 2. The present invention also designs a control component and a buffer component. During the vehicle driving process, due to the continuous high-speed forward movement of the vehicle, the airflow will squeeze the stress plate. The stress plate pushes the piston plate backward through the positioning plate and the mounting frame. At the same time, the sliding sleeve extracts the gas in the second telescopic tube through the second conduit, causing the second telescopic tube to contract. In this case, the rotating shaft rotates under the action of the first telescopic tube and the second telescopic tube, so that the outside gas can enter between the bottom plate and the side plate through the ventilation slot. In this way, the radiator can accelerate the air flow on the battery surface by discharging and extracting gas. It is worth mentioning that the above entire process can be automatically completed without manual cooperation. In addition, since the sealing component, the transmission component, the control component and the pressure component can all be made of lighter and less high-strength materials, the weight of the device is further reduced. This design not only improves the heat dissipation effect of the device, but also ensures its lightweight characteristics.

[0027] 3. The present invention also designs a buffer component and an anti-collision component. When the vehicle is driving on a potholed road section, the vehicle speed decreases, resulting in a decrease in the pressure on the force-bearing plate. When the auxiliary support contacts the ground and collides with the pulley, and then pushes the connecting plate and the sliding rod to move backward, the pressure in the second telescopic tube will be greater than the pressure in the first telescopic tube. At this time, the second telescopic tube extends, and the first telescopic tube contracts. When the first telescopic tube contracts, the gas inside it is injected into the sliding cylinder. After buffering the impact force, the auxiliary support and the pulley will quickly reset under the action of the elastic force of the second spring. At the same time, the rotating shaft rotates due to the adjustment of the first telescopic tube and the second telescopic tube, driving the sealing piece to fit the ventilation groove. This design has a dual function: on the one hand, it effectively alleviates the impact force on the chassis component through the buffering mechanism; on the other hand, the sealing piece fitting the ventilation groove can prevent the liquid in the pothole from splashing onto the battery surface, further ensuring the safety of the battery.

[0047] As Figures 1 to 8 shown, a new energy vehicle adjustable chassis involved in the present invention includes a chassis bracket 101, a drive assembly 102 and a battery rack 103, and further includes,

[0048] The frame mechanism 1 includes a chassis bracket 101, a drive assembly 102 disposed below the chassis bracket 101, and a battery rack 103, wherein the battery rack 103 is disposed below the chassis bracket 101; and, the chassis mechanism 2 includes a chassis assembly 201, a sealing assembly 202 located above the chassis assembly 201, a transmission assembly 203 connected to the chassis assembly 201, a pressure assembly 205 disposed in front of the chassis assembly 201, a control assembly 204, a buffer assembly 208, and an anti-collision assembly 209 located outside the transmission assembly 203. Among them, the buffer assembly 208 is connected to the chassis assembly 201, and the anti-collision assembly 209 is disposed in front of the buffer assembly 208. By designing the pressure assembly 205, the buffer assembly 208, the transmission assembly 203, and the control assembly 204, during driving, due to its own shape, the pressure assembly 205 will deform due to the pressure generated by the vehicle's contact with the airflow during driving. When encountering a potholed road section, first, the vehicle speed is reduced due to human control and the influence of the potholed road section. At the same time, when the chassis assembly 201 is about to collide with the ground, the anti-collision assembly 209 will contact the ground first. On the one hand, the device can dissipate heat by using the airflow generated during use, ensuring that the inside of the chassis assembly 201 is in a low-temperature state during the subsequent use, and avoiding the situation where the battery is damaged due to being in a high-temperature environment for a long time. On the other hand, when encountering a potholed road section, the device can not only effectively protect the chassis assembly 201 with a relatively light weight, but also quickly close the ventilation slot 2015 to prevent the continuous intrusion of liquid from the potholed road section into the battery, further ensuring the protection effect of the device on the battery and improving the safety of the device during use.

[0049] In an embodiment of the present invention, the lower part of the chassis bracket 101 is fixedly connected to the drive assembly 102, the lower part of the chassis bracket 101 is tightly welded to the upper part of the battery rack 103, the inner wall of the battery rack 103 is fixedly connected to the chassis assembly 201, the upper part of the chassis assembly 201 is snap-connected to the sealing assembly 202, two transmission assemblies 203 are arranged in the chassis assembly 201, and the two transmission assemblies 203 are respectively fixedly connected to the two control assemblies 204. The other ends of the two control assemblies 204 are respectively communicated with the two pressure assemblies 205 and the two buffer assemblies 208. An adjusting column 207 is slidably connected in the pressure assembly 205. One side of the pressure assembly 205 is fixedly connected to the mounting plate 206. The mounting plate 206 is fixedly connected to one side of the chassis assembly 201. The bottom end of the adjusting column 207 is located in the buffer assembly 208. The buffer assembly 208 is fixedly connected to one side of the chassis assembly 201. The other end of the buffer assembly 208 is fixedly connected to the anti-collision assembly 209. By designing the control assembly 204 and the buffer assembly 208, during driving, due to the continuous forward high-speed movement of the vehicle, the gas squeezes the force-bearing plate 2059, and the force-bearing plate 2059 will push the piston plate 2053 to move backward through the positioning plate 2058 and the mounting bracket 2057. The sliding sleeve 2081 will also extract the gas in the second telescopic tube 2044 through the second conduit 2047, and the second telescopic tube 2044 shrinks. At this time, the rotating shaft 2033 rotates under the influence of the first telescopic tube 2041 and the second telescopic tube 2044, so that the outside gas can enter between the bottom plate 2012 and the side plate 2011 through the ventilation slot 2015, enabling the radiator 2022 to accelerate the air flow rate on the surface of the battery by discharging and extracting gas. And the above process can be completed without manual cooperation. Moreover, since the sealing assembly 202, the transmission assembly 203, the control assembly 204, the pressure assembly 205, and the transmission assembly 203 can all use materials that are lighter and do not require high strength, the weight of the device is further reduced, thereby improving the heat dissipation effect of the device while ensuring the lightweight effect of the device.

[0050] In an embodiment of the present invention, the chassis assembly 201 includes four side plates 2011. The lower parts of the four side plates 2011 are fixedly connected to the upper part of the same bottom plate 2012. A plurality of contacts 2013 are arranged above the bottom plate 2012. The upper part of the bottom plate 2012 is tightly welded to the lower part of the protective shell 2014. A plurality of ventilation slots 2015 are opened outside each of the four side plates 2011. The lower part of the bottom plate 2012 is fixedly connected to the upper part of the battery rack 103. Two side plates 2011 on the same side are fixedly connected to the same transmission assembly 203. The mounting plate 206 and the buffer assembly 208 are both fixedly connected to a substrate arranged above the bottom plate 2012. The sealing assembly 202 includes a top plate 2021. A plurality of radiators 2022 are arranged above the top plate 2021. Two buckles 2023 are fixedly connected above the bottom plate 2012. The top plate 2021 is clamped to the side plates 2011 on both sides through the buckles 2023. By designing the buffer assembly 208 and the anti-collision assembly 209, when driving on a potholed road section, since the vehicle speed decreases, the pressure received by the force-bearing plate 2059 is reduced. It is ensured that when the auxiliary support 2091 and the pulley 2092 collide with the ground and push the connecting plate 2087 and the sliding rod 2085 to move backward, the pressure in the second telescopic tube 2044 can be greater than the pressure in the first telescopic tube 2041. At this time, the second telescopic tube 2044 will extend, while the first telescopic tube 2041 will contract. Since the first telescopic tube 2041 contracts, the gas in the first telescopic tube 2041 is injected into the sliding cylinder 2051. After the impact force is buffered by the auxiliary support 2091 and the pulley 2092, they will quickly return to their original positions under the action of the elastic force of the second spring 2084. The rotating shaft 2033 will also drive the sealing piece 2034 to fit the ventilation slot 2015 due to the adjustment of the first telescopic tube 2041 and the second telescopic tube 2044. On the one hand, the impact force when hitting the chassis assembly 201 can be relieved by buffering. On the other hand, it can effectively avoid the possibility of the liquid in the potholes splashing on the battery surface.

[0051] As another embodiment of the present invention, the transmission assembly 203 includes a plurality of fixed blocks 2031, and bearings 2032 are clamped in the plurality of fixed blocks 2031. A rotating shaft 2033 is sleeved in the bearing 2032. The bottom end of the rotating shaft 2033 is fixedly connected to the upper part of the sealing piece 2034. A transmission wheel 2035 is fixedly connected to the upper part of the rotating shaft 2033. The plurality of transmission wheels 2035 are connected by a transmission belt 2036. One of the rotating shafts 2033 is fixedly connected to the first reinforcement plate 2042 and the second reinforcement plate 2045. The first reinforcement plate 2042 is fixedly connected to the first telescopic tube 2041. The second reinforcement plate 2045 is fixedly connected to the second telescopic tube 2044. The first telescopic tube 2041 and the second telescopic tube 2044 are respectively communicated with the first conduit 2046 and the second conduit 2047 through a connecting pipe 2043 on the outside. The other end of the first conduit 2046 is communicated with the pressure assembly 205. The other end of the second conduit 2047 is communicated with the buffer assembly 208. The first telescopic tube 2041 and the second telescopic tube 2044 are both fixedly connected to one side of the side plate 2011 through the connecting pipe 2043. The sealing piece 2034 is located in the ventilation slot 2015 opened in one of the side plates 2011. The pressure assembly 205 includes a sliding cylinder 2051. A plurality of first springs 2052 are arranged in the sliding cylinder 2051, and the plurality of first springs 2052 are fixedly connected to one side of the inner wall of the sliding cylinder 2051. The other end of the first spring 2052 is fixedly connected to the piston plate 2053. The other side of the piston plate 2053 is fixedly connected to the push block 2054. An inclined slot 2055 is opened below the push block 2054. A sliding slot 2056 is opened below the sliding cylinder 2051. When driving on a potholed road section, since the vehicle speed decreases, the force-receiving plate 2059 is subjected to less pressure, ensuring that when the auxiliary support 2091 and the pulley 2092 collide with the ground and push the connecting plate 2087 and the sliding rod 2085 to move backward, the pressure in the second telescopic tube 2044 can be greater than the pressure in the first telescopic tube 2041, ensuring that the sealing piece 2034 can seal the ventilation slot 2015 when the auxiliary support 2091 and the pulley 2092 collide with the ground, preventing external water stains from entering the chassis assembly 201 and improving the safety of the battery during use.

[0052] As another embodiment of the present invention, the other side of the push block 2054 is fixedly connected to the mounting bracket 2057, the mounting bracket 2057 is fixedly connected to the positioning plate 2058, the lower part of the positioning plate 2058 is fixedly connected to the upper part of the force-bearing plate 2059. The force-bearing plate 2059 is arc-shaped. The sliding cylinder 2051 is fixedly connected to one side of the mounting plate 206. The adjusting column 207 is slidably connected in the chute 2056. The top end of the adjusting column 207 is lapped with the inclined chute 2055 opened under the push block 2054. The sliding cylinder 2051 is communicated with the first conduit 2046. The buffer assembly 208 includes sliding sleeves 2081. The number of the sliding sleeves 2081 is two, and the two sliding sleeves 2081 are communicated with each other. A through hole 2082 is opened on one side of one of the sliding sleeves 2081. Sealing plates 2083 are arranged in both of the two sliding sleeves 2081. The shape of the sealing plate 2083 is adapted to the shape of the inner wall of the sliding sleeve 2081. A second spring 2084 is arranged in the sliding sleeve 2081. The two ends of the second spring 2084 are respectively fixedly connected to one side of the inner wall of the sliding sleeve 2081 and the sealing plate 2083. The other side of the sealing plate 2083 is fixedly connected to the sliding rod 2085. The other end of the sliding rod 2085 passes through the support frame 2086 and is fixedly connected to the connecting plate 2087. The support frame 2086 is fixedly connected outside the sliding sleeve 2081. The sliding sleeve 2081 is fixedly connected to the side plate 2011 above the bottom plate 2012. The other side of the connecting plate 2087 is fixedly connected to the anti-collision assembly 209. The sliding sleeve 2081 is communicated with the second conduit 2047 through the through hole 2082. The anti-collision assembly 209 includes an auxiliary support 2091. A plurality of pulleys 2092 are arranged in the auxiliary support 2091. The auxiliary support 2091 is fixedly connected to four push rods 2093. And the four push rods 2093 are fixedly connected to two reinforcing ribs 2094. The bottom ends of the two reinforcing ribs 2094 are both fixedly connected to the auxiliary support 2091. The auxiliary support 2091 is arranged in an inclined manner. The other end of the push rod 2093 is fixedly connected to the connecting plate 2087. The auxiliary support 2091 is located under the force-bearing plate 2059. By arranging a plurality of pulleys 2092 in the auxiliary support 2091, when the auxiliary support 2091 collides with the ground, the pulleys 2092 can effectively convert the hard friction with the ground into rolling friction, thereby reducing the impact force between the auxiliary support 2091 and the chassis assembly 201. At the same time, due to the inclined arrangement, the auxiliary support 2091 can contact the ground through a plurality of pulleys 2092 to the greatest extent, ensuring the safety when relieving the impact force.

[0053] Working principle: This embodiment provides an adjustable chassis for a new energy vehicle. When in use, the battery needs to be placed in the chassis assembly 201, and then it can be used after being installed and sealed by the sealing assembly 202.

[0054] During the vehicle's driving process, due to its own shape, the pressure component 205 will deform under the pressure generated by contact with the airflow. The deformed pressure component 205 will push the adjustment column 207 to deform, and then the lower part of the adjustment column 207 will push the buffer component 208. The buffer component 208 will drive the anti-collision component 209 to extend outward. At the same time, the pressure component 205 will inject gas into the control component 204, while the buffer component 208 will extract gas. This series of actions causes the angle of the transmission component 203 to deflect. At this time, the sealing component 202 can accelerate the air flow on the surface of the battery in the chassis component 201 by discharging or extracting gas, thereby accelerating the heat dissipation efficiency of the battery. When the vehicle drives into a potholed road section, on the one hand, under the combined action of manual control and the road conditions of the potholed road section, the vehicle speed will decrease; on the other hand, when the chassis component 201 is about to collide with the ground, the anti-collision component 209 will contact the ground first. During the contact process, the anti-collision component 209 will push the buffer component 208 to deform to relieve the impact force, and at the same time inject gas into the control component 204. Subsequently, the control component 204 drives the sealing component 202 to recover, so that the sealing component 202 plays a role in shielding and protecting the chassis component 201;

[0055] During the vehicle's driving process, due to the vehicle continuously moving forward at high speed, the airflow will squeeze the force-receiving plate 2059. After being squeezed, the force-receiving plate 2059 will push the piston plate 2053 to move backward by means of the positioning plate 2058 and the mounting bracket 2057. This action causes the gas in the sliding cylinder 2051 to quickly enter the first telescopic tube 2041 along the first conduit 2046, thereby prompting the first telescopic tube 2041 to extend. At the same time, the adjustment column 207 moves upward due to the lower connecting plate 2087 being squeezed. The upward movement of the adjustment column 207 drives the sliding sleeve 2081 to act. The sliding sleeve 2081 extracts the gas in the second telescopic tube 2044 through the second conduit 2047, causing the second telescopic tube 2044 to contract. Under the combined action of the extension of the first telescopic tube 2041 and the contraction of the second telescopic tube 2044, the rotating shaft 2033 rotates. After the rotating shaft 2033 rotates, the outside gas can enter the space between the bottom plate 2012 and the side plate 2011 through the ventilation slot 2015;

[0056] When the vehicle travels to a potholed section, the vehicle speed decreases, causing the pressure on the force-bearing plate 2059 to decrease. At this time, if the auxiliary support 2091 contacts the ground and collides with the pulley 2092, it will push the connecting plate 2087 and the sliding rod 2085 to move backward. During this process, the pressure in the second telescopic tube 2044 will be greater than the pressure in the first telescopic tube 2041, resulting in the extension of the second telescopic tube 2044 and the contraction of the first telescopic tube 2041. As the first telescopic tube 2041 contracts, the gas inside it is injected into the sliding cylinder 2051. After buffering the impact force, the auxiliary support 2091 and the pulley 2092 will quickly reset under the action of the elastic force of the second spring 2084. At the same time, the rotating shaft 2033 will rotate according to the adjustment of the first telescopic tube 2041 and the second telescopic tube 2044, thereby driving the sealing piece 2034 to fit the air exchange groove 2015.
