With the rapid development of the battery industry, the technical solutions for using battery devices as a power source for vehicles are becoming increasingly mature.

[0003] Since electric vehicles are subject to conditions such as wading through water and rain, sealing is very important for them. How to improve the sealing performance of vehicles has always been a key focus for those skilled in the art. Utility Model Content

[0004] In view of the above problems, this application provides a vehicle chassis and a vehicle, the chassis of which is beneficial to improving the sealing performance of the vehicle.

[0005] In a first aspect, this application provides a vehicle chassis, the vehicle chassis including a frame and an energy compartment, the frame including two longitudinal beams arranged opposite each other along a first direction; the energy compartment including a battery cell, a first protective plate and two crossbeams arranged opposite each other along a second direction, the crossbeams being connected between the two longitudinal beams, the first protective plate being connected to the longitudinal beams and the crossbeams to form a first cavity with an opening at one end, the battery cell being accommodated in the first cavity, the orientation of the opening, the second direction and the first direction being perpendicular to each other; the crossbeams having a first sealing structure on the end face facing the opening, the first sealing structure being used for a sealed connection with the vehicle body.

[0006] In the above structure, since the crossbeam of the energy compartment has a first sealing structure on the end face facing the opening, the first sealing structure is used to seal the connection with the vehicle body. When the vehicle body is connected to the chassis, the first cavity in the energy compartment that holds the battery cells can form a well-sealed space, which improves the vehicle's sealing performance and reduces the possibility of external water, dust and other impurities affecting the battery cells in the vehicle.

[0007] According to some embodiments of this application, the vehicle chassis further includes a range extender compartment. The range extender compartment includes a second skid plate and a fuel tank. The second skid plate is connected to longitudinal beams and cross beams to form a second cavity for accommodating the fuel tank. The second cavity and the first cavity are arranged along a second direction. Because the range extender compartment in the chassis is provided with a second cavity for accommodating the fuel tank, the vehicle can be refueled to increase its driving range, which is beneficial to improving the vehicle's driving range and enhancing the driving experience.

[0008] According to some embodiments of the present application, the chassis of the vehicle includes a range extender compartment and a reinforcing beam connected to the second skid plate. The reinforcing beam is connected between two longitudinal beams, which not only allows the load of objects such as fuel tanks in the range extender compartment to be transferred to the second skid plate and then to the vehicle frame via the reinforcing beam, but also allows the second skid plate to better support objects such as fuel tanks in the range extender compartment.

[0009] According to some embodiments of the present application, the chassis of the vehicle is provided with a first sealing structure made of putty, rubber strips or foam, which makes the first sealing structure have a good sealing effect and enables the first sealing structure to provide a good seal at the connection between the crossbeam and the frame.

[0010] According to some embodiments of this application, the chassis of a vehicle includes a crossbeam comprising a peripheral wall and a support wall. The peripheral wall forms an inner cavity of the crossbeam, and the support wall is located within the inner cavity and connected to the peripheral wall along the orientation of the opening. With this structure, the crossbeam not only helps reduce the weight of the energy compartment, contributing to vehicle lightweighting, but also better supports the load (weight load) experienced by the energy compartment in a direction parallel to the orientation of the opening.

[0011] According to some embodiments of this application, the chassis of a vehicle has a second sealing structure on the end face of the longitudinal beam facing the opening. The second sealing structure is used to seal the connection with the vehicle body, which can improve the sealing performance of the first cavity and reduce the possibility of external water, dust and other impurities entering the first cavity.

[0012] According to some embodiments of the present application, the chassis of the vehicle is made of putty, rubber strips or foam, which makes the second sealing structure have a good sealing effect and enables the second sealing structure to effectively seal the connection between the crossbeam and the frame.

[0013] According to some embodiments of this application, the chassis of a vehicle has a first guard plate welded to the longitudinal beams and the transverse beams, which allows the first guard plate to be well sealed to the longitudinal beams and the transverse beams. This is beneficial to improving the sealing of the energy compartment and helps to reduce the possibility of external water, dust and other impurities entering the energy compartment and affecting the battery cells in the vehicle.

[0014] Secondly, this application provides a vehicle comprising the chassis and body of the vehicle provided by any of the aforementioned technical solutions, wherein the body is connected to the crossbeams and longitudinal beams of the chassis and covers the opening, and a first sealing structure is sandwiched between the crossbeams and the body.

[0015] According to some embodiments of this application, the vehicle body is bolted to the crossbeams and longitudinal beams, making disassembly convenient and maintenance easy.

[0016] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0017] This application provides a vehicle chassis comprising a frame and an energy compartment. The frame includes two longitudinal beams arranged opposite each other along a first direction. The energy compartment includes battery cells, a first protective plate, and two crossbeams arranged opposite each other along a second direction. The crossbeams connect the two longitudinal beams. The first protective plate connects the longitudinal beams and the crossbeams to form a first cavity with an opening at one end. The battery cells are housed in the first cavity, and the orientation of the opening, the second direction, and the first direction are perpendicular to each other. The crossbeams have a first sealing structure on the end face facing the opening, which is used for a sealed connection with the vehicle body. In this structure, because the crossbeams of the energy compartment have a first sealing structure on the end face facing the opening, and the first sealing structure is used for a sealed connection with the vehicle body, when the vehicle body is connected to the chassis, the first cavity in the energy compartment that houses the battery cells can form a well-sealed space, improving the vehicle's airtightness and reducing the possibility of external water, dust, and other impurities affecting the battery cells in the vehicle.

[0034] As vehicle technology continues to develop, people have increasingly higher requirements for vehicle reliability. In particular, with the widespread application of electric vehicles powered by batteries, people are paying more and more attention to vehicle reliability.

[0035] The vehicle has a battery pack installed inside, which can be located at the bottom, front, or rear of the vehicle. The battery pack can be used to power the vehicle; for example, it can serve as the vehicle's operating power source.

[0036] The vehicle may also include a controller and a motor, with the controller controlling the battery device to power the motor, for example, for the power needs of starting, navigating and driving the vehicle.

[0037] In some embodiments of this application, the battery device can not only serve as the operating power source for the vehicle, but also as the driving power source for the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0038] Since vehicles need to operate outdoors, they often encounter scenarios such as wading through water and getting wet in the rain. Battery devices are also prone to short circuits when exposed to water. Therefore, creating a sealed environment for battery devices in vehicles and improving the vehicle's sealing performance has always been a concern for those skilled in the art.

[0039] To improve vehicle sealing, this application provides a vehicle chassis comprising a frame and an energy compartment. The frame includes two longitudinal beams arranged opposite each other along a first direction. The energy compartment includes battery cells, a first protective plate, and two crossbeams arranged opposite each other along a second direction. The crossbeams connect the two longitudinal beams. The first protective plate connects the longitudinal beams and the crossbeams to form a first cavity with an opening at one end. The battery cells are housed in the first cavity, and the opening orientation, the second direction, and the first direction are perpendicular to each other. The crossbeams have a first sealing structure on the end face facing the opening, which is used for sealing connection with the vehicle body. In the above structure, because the crossbeams of the energy compartment have a first sealing structure on the end face facing the opening, and the first sealing structure is used for sealing connection with the vehicle body, when the vehicle body is connected to the chassis, the first cavity in the energy compartment that houses the battery cells can form a well-sealed space, improving the vehicle's sealing performance and reducing the possibility of external water, dust, and other impurities affecting the battery cells in the vehicle.

[0040] The technical solutions described in the embodiments of this application are applicable to vehicles. Vehicles can be gasoline-powered vehicles, natural gas-powered vehicles, or new energy vehicles; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc.

[0041] The chassis and technical solutions of the vehicle provided in the specific embodiments of this application will be further described below.

[0042] Some embodiments of this application provide a vehicle chassis, with reference to... Figure 1 The vehicle chassis includes a frame 1 and an energy compartment 2. The frame 1 includes two longitudinal beams 11 arranged opposite each other along a first direction X. The energy compartment 2 includes battery cells (not shown in the figure), a first protective plate 21, and two crossbeams 22 arranged opposite each other along a second direction Y. The crossbeams 22 are connected between the two longitudinal beams 11. The first protective plate 21 is connected to the longitudinal beams 11 and the crossbeams 22 to form a first cavity 23 with an opening at one end. The battery cells are accommodated in the first cavity 23. The opening is perpendicular to the Z direction, the second direction Y direction, and the first direction X direction. Figure 2 and Figure 3 The crossbeam 22 has a first sealing structure 24 on the Z-facing end face of the opening, and the first sealing structure 24 is used for sealing connection with the vehicle body 4.

[0043] The frame 1 can be the main frame of the chassis, wherein the longitudinal beams 11 are beams that are spaced apart relative to each other along a first direction X. For example, the first direction X can be the left-right direction of the vehicle.

[0044] Energy compartment 2 can be a cabin structure in a vehicle used to provide electrical energy. The battery cells can be secondary batteries, which are battery cells that can be recharged after being discharged to activate the active materials and continue to be used.

[0045] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0046] The energy compartment 2 can contain multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar to form a battery cell assembly. This assembly can be a battery module, which consists of multiple battery cells arranged and fixed together to form an independent module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0047] The crossbeam 22 can be a beam structure within the energy compartment 2, connected to other components within the energy compartment 2, capable of supporting the load within the energy compartment 2 and transferring the load to the frame 1. As the main load-bearing component in the energy compartment 2, the crossbeam 22 connects between two longitudinal beams 11, enabling the transfer of the load from the energy compartment 2 to the frame 1. The two crossbeams 22 are arranged at relative intervals along a second direction Y, allowing them to transfer the load from the energy compartment 2 to the frame 1 from both ends of the second direction Y. Exemplarily, the second direction Y can be the vehicle's forward direction.

[0048] By connecting two spaced-apart crossbeams 22 between two spaced-apart longitudinal beams 11, the two crossbeams 22 and the two longitudinal beams 11 can enclose a space for placing battery cells. The first protective plate 21 can be a plate-like component in the energy compartment 2, connected to the longitudinal beams 11 and the crossbeams 22. As a component for holding battery cells, the first protective plate 21, connected to the longitudinal beams 11 and the crossbeams 22, can together with the longitudinal beams 11 and the crossbeams 22 form a first cavity 23 for accommodating battery cells. One end of the first cavity 23 has an opening, allowing battery cells to be inserted into the first cavity 23 through the opening. Exemplarily, the opening can be oriented vertically upwards (Z), allowing installers to easily insert battery cells into the first cavity 23 from above.

[0049] By making the openings perpendicular to each other in the Z direction, the second direction Y, and the first direction X, the various components in the chassis can be arranged more conveniently.

[0050] The chassis of the vehicle is connected to the body 4 and can cover the opening of the first cavity 23, so that the first cavity 23 can form a sealed space, and the battery cells in the first cavity 23 can be protected by the first protective plate 21, the longitudinal beam 11 and the cross beam 22.

[0051] The first sealing structure 24 can be a structure used to seal the connection between the crossbeam 22 and the body 4. It is used to improve the sealing performance of the first cavity 23 and reduce the possibility of external water, dust and other impurities entering the first cavity 23.

[0052] In the above structure, since the crossbeam 22 of the energy compartment 2 is provided with a first sealing structure 24 on the Z-facing end face of the opening, the first sealing structure 24 is used to seal the connection with the vehicle body 4, so that when the vehicle body 4 is connected to the chassis, the first cavity 23 in the energy compartment 2 that contains the battery cells can form a well-sealed space, which improves the sealing performance of the vehicle and reduces the possibility of external water, dust and other impurities affecting the battery cells in the vehicle.

[0053] In some embodiments, the vehicle chassis further includes a range extender compartment 3, which includes a second guard plate 31 and a fuel tank (not shown in the figure). The second guard plate 31 is connected to the longitudinal beam 11 and the cross beam 22 to form a second cavity for accommodating the fuel tank. The second cavity and the first cavity 23 are arranged along a second direction Y.

[0054] The range extender compartment 3 can be a cabin structure that can extend the driving range of an electric vehicle, and it is used to house the fuel tank. The second protective plate 31 can be a plate-like component in the range extender compartment 3. The second protective plate 31 is connected to the longitudinal beam 11 and the transverse beam 22. Specifically, the second protective plate 31 can be connected between two longitudinal beams 11 and connected to the side of a transverse beam 22 away from the energy compartment 2.

[0055] By connecting the second guard plate 31 to the longitudinal beam 11 and the transverse beam 22 to form a second cavity for accommodating the fuel tank, the second cavity and the first cavity 23 are arranged sequentially along the second direction Y, so that the range extender 3 and the energy compartment 2 can be conveniently arranged in the chassis.

[0056] By incorporating a second chamber in the chassis to house the fuel tank, the vehicle can be refueled to extend its driving range, thereby improving both the driving range and the overall driving experience.

[0057] In some embodiments, the range extender 3 also includes a reinforcing beam 32 connected to the second guard plate 31, the reinforcing beam 32 being connected between the two longitudinal beams 11.

[0058] The reinforcing beam 32 can be a beam structure used to improve the structural strength of the range extender 3. By connecting the reinforcing beam 32 to the second guard plate 31, not only can the load of objects such as fuel tanks in the range extender 3 be transferred to the second guard plate 31 and then transferred outward via the reinforcing beam 32, but the second guard plate 31 can also better support objects such as fuel tanks in the range extender 3.

[0059] By connecting the reinforcing beam 32 between the two longitudinal beams 11, the load of objects such as fuel tanks in the extended range cabin 3 can be better transferred to the longitudinal beams 11 through the reinforcing beam 32, which helps to improve the stability of the extended range cabin 3.

[0060] In some embodiments, the material of the first sealing structure 24 is putty, adhesive strip, or foam.

[0061] The material of the first sealing structure 24 is putty, rubber strip, or foam. Specifically, the first sealing structure 24 may be made of putty, rubber strip, or foam.

[0062] By using putty, rubber strips, or foam to make the first sealing structure 24, the first sealing structure 24 has a good sealing effect, enabling the first sealing structure 24 to effectively seal the connection between the crossbeam 22 and the frame 1.

[0063] In some embodiments, the crossbeam 22 includes a peripheral wall 221 and a support wall 222. The peripheral wall 221 forms an inner cavity of the crossbeam 22, and the support wall 222 is located in the inner cavity and is connected to the peripheral wall 221 along the Z-direction of the opening.

[0064] The peripheral wall 221 and the supporting wall 222 are different wall structures in the crossbeam 22. The peripheral wall 221 can be a wall structure that encloses the inner cavity of the crossbeam 22, and the supporting wall 222 can be a wall structure that is set in the inner cavity to play a supporting role.

[0065] By making the peripheral wall 221 form the inner cavity of the crossbeam 22, the crossbeam 22 becomes a hollow structure, which helps to reduce the weight of the energy compartment 2 and contributes to the vehicle's lightweight design. The support wall 222 is located in the inner cavity and connected to the peripheral wall 221 along the Z-direction of the opening. Alternatively, the support wall 222 can be disposed in the inner cavity and connected to two walls of the peripheral wall 221 that are arranged opposite each other along the Z-direction of the opening, so that the support wall 222 can better support the load (weight load) on the energy compartment 2 in the direction parallel to the Z-direction of the opening.

[0066] In some embodiments, the longitudinal beam 11 has a second sealing structure 25 on the Z-facing end face of the opening, the second sealing structure 25 being used for a sealed connection with the vehicle body 4.

[0067] The second sealing structure 25 can be a structure used to seal the connection between the longitudinal beam 11 and the body 4. It is used to improve the sealing performance of the first cavity 23 and reduce the possibility of external water, dust and other impurities entering the first cavity 23.

[0068] By providing a second sealing structure 25 on the Z-facing end face of the longitudinal beam 11 along the opening, and a first sealing structure 24 on the Z-facing end face of the transverse beam 22 along the opening, a sealing structure can be provided around the opening, so that the vehicle body 4 connected to the chassis can seal and cover the opening, thereby improving the sealing performance of the first cavity 23.

[0069] In some embodiments, the material of the second sealing structure 25 is putty, adhesive strip, or foam.

[0070] The material of the second sealing structure 25 can be putty, rubber strip, or foam. Specifically, the second sealing structure 25 can be made of putty, rubber strip, or foam.

[0071] By using putty, rubber strips, or foam to make the second sealing structure 25, the second sealing structure 25 has a good sealing effect, enabling the second sealing structure 25 to effectively seal the connection between the crossbeam 22 and the frame 1.

[0072] In some embodiments, the first guard plate 21 is welded to the longitudinal beam 11 and the transverse beam 22.

[0073] Since welding can melt materials together, by welding the first protective plate 21 to the longitudinal beam 11 and the transverse beam 22, the first protective plate 21 can be well sealed to the longitudinal beam 11 and the transverse beam 22, which helps to improve the sealing performance of the energy compartment 2 and helps to reduce the possibility of external water, dust and other impurities entering the energy compartment 2 and affecting the battery cells in the vehicle.

[0074] Some embodiments of this application also provide a vehicle, which includes a chassis and a body 4 as provided in the above technical solutions. The body 4 is connected to the crossbeam 22 and the longitudinal beam 11 of the chassis and covers the opening. A first sealing structure 24 is sandwiched between the crossbeam 22 and the body 4.

[0075] The vehicle body 4 is connected to the crossbeams 22 and longitudinal beams 11 of the chassis, allowing the vehicle body 4 to be firmly connected to the chassis and cover the opening of the first cavity 23 of the chassis. Since the chassis of this vehicle is the chassis of the vehicle provided by the above-mentioned technical solution, the vehicle body 4 can be sealed to the crossbeams 22 and longitudinal beams 11 of the chassis, improving the sealing performance of the first cavity 23, reducing the possibility of external water, dust and other impurities entering the first cavity 23 and affecting the battery cells in the vehicle, thus improving the vehicle's sealing performance and contributing to improved vehicle reliability.

[0076] In some embodiments, the vehicle body 4 is bolted to the crossbeam 22 and the longitudinal beam 11.

[0077] Bolted connections allow for easy assembly and disassembly. The body 4 is bolted to the crossbeam 22 and the longitudinal beam 11, making it easy to assemble and disassemble the body 4 and the frame 1, which improves the convenience of installation and maintenance.

[0078] For example, the body 4 can be connected to the crossbeam 22 and the longitudinal beam 11 by a flow drill screw process, so that the crossbeam 22 and the longitudinal beam 11 can be firmly connected to the sheet metal structure of the body 4.

[0079] Some embodiments of this application provide a Figure 1The chassis of the vehicle shown includes a frame 1, an energy compartment 2, and a range extender compartment 3. The energy compartment 2 includes battery cells, a first protective plate 21, and two crossbeams 22 arranged opposite each other along a second direction Y. The crossbeams 22 are connected between two longitudinal beams 11. The first protective plate 21 is connected to the longitudinal beams 11 and the crossbeams 22 to form a first cavity 23 with an opening at one end. The battery cells are housed in the first cavity 23, and the opening is perpendicular to the Z-direction, the second direction Y, and the first direction X. The crossbeams 22 have a first sealing structure 24 on the Z-direction end face of the opening, and the longitudinal beams 11 have a second sealing structure 25 on the Z-direction end face of the opening. The range extender compartment 3 and the energy compartment 2 are arranged along the second direction Y. The second protective plate 31 of the range extender compartment 3 is connected to the crossbeams 22 and the longitudinal beams 11 to form a second cavity that houses the fuel tank.

[0080] In the above structure, since the crossbeam 22 of the energy compartment 2 is provided with a first sealing structure 24 on the Z-facing end face of the opening, the first sealing structure 24 is used to seal the connection with the vehicle body 4, so that when the vehicle body 4 is connected to the chassis, the first cavity 23 in the energy compartment 2 that contains the battery cells can form a well-sealed space, which improves the sealing performance of the vehicle and reduces the possibility of external water, dust and other impurities affecting the battery cells in the vehicle.
