Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a vehicle frame and a vehicle. Background Technology

[0002] In electric vehicles, as the power battery is repeatedly charged and discharged, the water-cooling plate used to dissipate heat from the power battery will deform due to the expansion of the power battery cells, thereby squeezing the coolant inside the water-cooling plate into the expansion tank.

[0003] However, if the deformation of the water-cooling plate is too large, such that the volume of coolant squeezed out of the plate exceeds the capacity of the expansion tank, coolant will overflow from the expansion tank. In related technologies, to solve this problem, an overflow tank connected to the expansion tank is added near the bumper beam to collect the coolant overflowing from the expansion tank.

[0004] Of the two solutions mentioned above, the first solution involves adding an expansion tank inside the vehicle, which requires additional interior space. The second solution involves adding both an expansion tank and an overflow tank inside the vehicle, which together occupy even more space. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a vehicle frame that can improve the problem of adding an expansion tank inside the vehicle in the first solution mentioned above, which requires additional space inside the vehicle; or improve the problem of adding both an expansion tank and an overflow tank inside the vehicle in the second solution mentioned above, which requires even more space together.

[0006] This utility model also proposes a vehicle having the above-mentioned vehicle frame.

[0007] According to a first aspect of the present invention, a vehicle frame includes a beam assembly, wherein the beam assembly includes a beam body;

[0008] The beam defines a liquid storage space, and the beam is provided with an overflow inlet communicating with the liquid storage space and a vent communicating with the liquid storage space; wherein, the vent is located higher than the bottom wall of the liquid storage space.

[0009] The vehicle frame according to the embodiment of this utility model has at least the following beneficial effects:

[0010] The vehicle frame of this utility model utilizes existing beams as containers to hold coolant overflowing from the liquid cooling plate. The beams can directly replace the expansion tank or overflow tank in related technologies. This improves the problem caused by the need to set up an expansion tank or overflow tank in related technologies, increases the usable space inside the vehicle, and is beneficial for the arrangement of other parts.

[0011] According to some embodiments of the present invention, the beam has a partition disposed within the liquid storage space, the partition dividing the liquid storage space into multiple chambers, the multiple chambers being interconnected.

[0014] According to some embodiments of the present invention, the beam assembly further includes a vent pipe, which is located outside the beam body and connected to the outer wall of the beam body, with one end of the vent pipe communicating with the vent and the other end facing downwards.

[0015] According to some embodiments of this utility model, a vertical plane is defined as a reference plane, the projection of the beam on the reference plane is the first projection, the projection of the vent pipe on the reference plane is the second projection, the top of the first projection is higher than the top of the second projection, and the bottom of the first projection is lower than the bottom of the second projection.

[0016] According to some embodiments of this utility model, the vent pipe is a bent pipe.

[0017] According to some embodiments of the present invention, the beam assembly further includes a valve; the beam body is also provided with a drain port communicating with the liquid storage space, and the valve is located at the drain port; wherein, the vent is positioned higher than the drain port.

[0018] According to some embodiments of the present invention, the beam body includes a beam body and two sealing plates. The beam body is a hollow structure, and the two sealing plates are spaced apart within the beam body along the length direction of the beam body.

[0019] A vehicle according to a second aspect of the present invention includes: a vehicle frame as described above; a liquid cooling plate having a coolant flow channel; a first overflow pipe, one end of which is connected to the coolant flow channel and the other end of which is connected to the overflow inlet, and the liquid storage space is used to receive coolant overflowing from the coolant flow channel.

[0020] The vehicle according to the embodiments of this utility model has at least the following beneficial effects:

[0021] When the liquid cooling plate is squeezed by the battery cells, causing coolant to overflow from the liquid cooling plate's cooling channels, the coolant can enter the reservoir space of the beam through the first overflow pipe.

In the above embodiment, the vehicle directly utilizes the existing beam in the vehicle frame as a container for the coolant overflowing from the water-cooling plate, reducing the need for other separate containers.

The intermediate container can be an expansion tank. In this embodiment, the vehicle directly utilizes the existing beam in the vehicle frame as a container for the coolant overflowing from the intermediate container. The beam can directly replace the overflow tank in related technologies, eliminating the need for an overflow tank. This improves upon the problem of requiring additional expansion tanks and overflow tanks in related technologies, increases the usable space inside the vehicle, and facilitates the arrangement of other components.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] Figure 1 The illustration shows a partial structure of a vehicle frame according to an embodiment of the present invention. The vehicle frame can be applied to a vehicle, which can be a private car, such as a sedan, SUV, MPV, or pickup truck; or a commercial vehicle, such as a van, bus, small truck, or large trailer.

[0042] The vehicle frame is the foundation of the entire vehicle and mainly serves a load-bearing function. The vehicle frame includes beam assembly 100, and beam assembly 100 includes beam body 110.

[0043] It should be noted that the vehicle frame itself includes various beams, such as the front bumper beam 400, the rear bumper beam, the left longitudinal beam 200, and the right longitudinal beam 300, while the beam 110 in the beam assembly 100 can be the front bumper beam 400, the rear bumper beam, the left longitudinal beam 200, or the right longitudinal beam 300.

[0044] Specifically, in this embodiment, the left longitudinal beam 200 and the right longitudinal beam 300 are arranged side by side and spaced apart, and the front ends of the left longitudinal beam 200 and the right longitudinal beam 300 are both connected to the front anti-collision beam 400. The beam body 110 in the beam assembly 100 is the right longitudinal beam 300.

[0045] It should be noted that the directions of up, down, front, back, left, and right involved in this utility model refer to the vehicle's position in the O-XYZ coordinate system. The origin O coincides with the vehicle's center of mass. The front end refers to the X direction parallel to the ground pointing forward, the rear end refers to the X direction parallel to the ground pointing backward, the left side refers to the Y direction parallel to the ground pointing to the driver's left, the right side refers to the Y direction parallel to the ground pointing to the driver's right, the upper end refers to the Z direction passing through point O pointing upward, and the lower end refers to the Z direction passing through point O pointing downward.

[0046] The beam body 110 of the beam assembly 100 is configured as a container capable of storing liquid; that is, the beam body 110 of the beam assembly 100 not only serves its original load-bearing function but also serves to store overflow liquid.

[0047] Combination Figure 2 and Figure 3 Specifically, the beam body 110 of the beam assembly 100 defines a liquid storage space 110a; the beam body 110 is provided with an overflow inlet 110b communicating with the liquid storage space 110a and a vent 110c communicating with the liquid storage space 110a; wherein, the vent 110c is located higher than the bottom wall of the liquid storage space 110a.

[0048] Specifically, the beam 110 includes a main beam 111 and two sealing plates 112. The main beam 111 is a hollow structure, and the two sealing plates 112 are spaced apart within the main beam 111 along its length. The main beam 111 and the two sealing plates 112 together define a liquid storage space 110a. An overflow inlet 110b is located at the top of the beam 110, and a vent 110c is located on the side of the beam 110. Of course, in other embodiments, the overflow inlet 110b and / or the vent 110c may be located elsewhere on the beam 110.

[0049] It should be noted that the vehicle frame using the above embodiment also includes a power battery and a liquid cooling plate; wherein, the liquid cooling plate is attached to the battery cell of the power battery and is used to dissipate heat from the battery cell; after repeated charging and discharging, the battery cell will expand and squeeze the liquid cooling plate, causing the liquid cooling plate to undergo irreversible deformation, which reduces the volume of the coolant flow channel of the liquid cooling plate.

[0050] In some embodiments, the vehicle further includes a first overflow pipe; one end of the first overflow pipe is connected to the coolant channel of the liquid cooling plate, and the other end is connected to the overflow inlet 110b of the beam 110; wherein the liquid storage space 110a of the beam 110 is used to receive the coolant overflowing from the coolant channel of the water cooling plate.

[0051] It should be noted that when the liquid cooling plate is squeezed by the battery cells, causing the coolant in the liquid cooling plate's cooling channel to overflow, the coolant can enter the liquid storage space 110a of the beam 110 through the first overflow pipe. Since a vent 110c is provided on the beam 110 at a position higher than the bottom wall of the liquid storage space 110a, the air pressure in the liquid storage space 110a can be balanced with the outside air pressure, so that the coolant overflowing from the liquid cooling plate's cooling channel can smoothly enter the liquid storage space 110a.

[0052] It should also be noted that the vehicle frame using the above embodiment directly uses the existing beam 110 in the frame as a container for coolant overflowing from the water-cooling plate, which reduces the need for other separate containers. This improves the problem caused by the need to set up an expansion tank in related technologies, increases the usable space inside the vehicle, and is beneficial for the arrangement of other parts.

[0053] Furthermore, a coolant overflow port can be provided at the top of the coolant flow channel of the water-cooled plate. One end of the first overflow pipe is connected to the coolant overflow port, and the other end is connected to the overflow inlet 110b. When the coolant in the coolant flow channel of the water-cooled plate overflows through the coolant overflow port, the coolant can flow along the first overflow pipe into the liquid storage space 110a of the beam 110.

[0054] It should be noted that a pump body may be installed on the vehicle, which is used to pump the coolant that overflows into the first overflow pipe into the liquid storage space 110a of the beam 110.

[0055] Combination Figure 3 and Figure 4 In other embodiments, the vehicle using the frame of the above embodiments further includes an intermediate container 500, a second overflow pipe, and a third overflow pipe 600; wherein, the two ends of the second overflow pipe are respectively connected to the coolant flow channel of the water-cooled plate and the receiving cavity of the intermediate container 500, and the two ends of the third overflow pipe 600 are respectively connected to the receiving cavity of the intermediate container 500 and the overflow inlet 110b of the beam 110; wherein, the receiving cavity of the intermediate container 500 is used to receive the coolant overflowing from the coolant flow channel of the water-cooled plate, and the liquid storage space 110a of the beam 110 is used to receive the coolant overflowing from the receiving cavity of the intermediate container 500.

[0056] It should be noted that when the liquid cooling plate is squeezed by the battery cells, causing the coolant in the cooling channel of the liquid cooling plate to overflow, the coolant can enter the receiving cavity of the intermediate container 500 through the second overflow pipe. When the volume of coolant entering the intermediate container 500 reaches the holding limit of the intermediate container 500, the coolant can overflow from the intermediate container 500 and enter the liquid storage space 110a of the beam 110 through the third overflow pipe 600. The intermediate container 500 can be an expansion tank.

[0057] It should also be noted that the vehicle frame using the above embodiment directly uses the existing beam 110 in the frame as a container for the coolant overflowing from the intermediate container 500. The beam 110 can directly replace the overflow tank in the related technology, eliminating the need for the overflow tank. This improves the problem caused by the need to set up an expansion tank and an overflow tank simultaneously in the related technology, increases the usable space inside the vehicle, and is beneficial for the arrangement of other parts.

[0058] Furthermore, a coolant overflow port can be provided at the top of the coolant flow channel of the water-cooled plate; the intermediate container 500 is also provided with an inlet communicating with its receiving cavity and an overflow port communicating with its receiving cavity. The overflow port can be located at the top of the intermediate container 500 or at a position on the upper side of the intermediate container 500; one end of the second overflow pipe is connected to the coolant overflow port of the water-cooled plate and the other end is connected to the inlet of the intermediate container 500; one end of the third overflow pipe 600 is connected to the overflow port of the intermediate container 500 and the other end is connected to the overflow inlet 110b of the beam 110. Thus, when the coolant in the coolant channel of the water-cooled plate overflows through the coolant overflow port, the coolant can flow into the receiving cavity of the intermediate container 500 along the second overflow pipe. When the volume of coolant entering the intermediate container 500 reaches the holding limit of the intermediate container 500, the coolant can overflow from the overflow port of the intermediate container 500 and enter the liquid storage space 110a of the beam 110 through the third overflow pipe 600.

[0059] It should be noted that the vehicle may be equipped with a pump body, which is used to pump the coolant overflowing into the second overflow pipe into the receiving cavity of the intermediate container 500, and / or to pump the coolant overflowing into the third overflow pipe 600 into the liquid storage space 110a of the beam 110.

[0060] like Figure 3 As shown, in some embodiments, the beam 110 has a partition 113 disposed in the liquid storage space 110a, the partition 113 dividing the liquid storage space 110a into a plurality of chambers 110e, the plurality of chambers 110e being interconnected.

[0061] Understandably, the separator 113 divides the liquid storage space 110a into multiple chambers 110e, and the overflow inlet 110b is connected to any of the chambers 110e. In this way, the coolant flowing into the liquid storage space 110a of the beam 110 through the overflow inlet 110b can be distributed in multiple chambers 110e. The separator 113 can improve the noise problem caused by coolant sloshing and improve the passenger experience.

[0062] It should be noted that the interconnection of multiple chambers 110e means that each chamber 110e can be directly or indirectly connected.

[0063] Furthermore, the inner end of the vent 110c penetrates the side wall or top wall of one of the uppermost chambers 110e, and the vent 110c is positioned higher than the bottom wall of that chamber 110e. This ensures that each chamber 110e can function as a liquid storage container.

[0064] The partition 113 includes a first partition 1131 and a second partition 1132, which are arranged crosswise. The first partition 1131 has a first connecting port 11311 that connects the chambers 110e on both sides of it. The second partition 1132 has a second connecting port 11321 that connects the chambers 110e on both sides of it.

[0065] Understandably, the liquid storage space 110a can be divided into multiple chambers 110e by the combined action of the first partition 1131 and the second partition 1132; and by opening a first connecting port 11311 on the first partition 1131 and a second connecting port 11321 on the second partition 1132, the multiple chambers 110e can be interconnected.

[0066] It should be noted that a first connecting port 11311 can also be provided on the first partition 1131 alone, or a second connecting port 11321 can be provided on the second partition 1132 alone. This can also form multiple interconnected chambers 110e. As long as the coolant entering the liquid storage space 110a can be dispersed and flow into multiple chambers 110e, the problem of noise caused by coolant sloshing can be improved.

[0067] Specifically, in this embodiment, the first partition 1131 is a horizontal partition, and the second partition 1132 is a vertical partition. The first partition 1131 and the second partition 1132 are arranged perpendicularly, and the first partition 1131 and the second partition 1132 can be an integral structure.

[0068] It should be noted that the number of first partitions 1131 can be one or more, and the number of second partitions 1132 can also be one or more; for each layer of multiple chambers 110e arranged horizontally, a second connecting port 11321 connecting the two adjacent chambers 110e is provided on the second partition 1132 between each two adjacent chambers 110e; for each column of multiple chambers 110e arranged vertically, a first connecting port 11311 connecting the two adjacent chambers 110e is provided on the first partition 1131 between each two adjacent chambers 110e.

[0069] It is understandable that a second connecting port 11321 may not be provided between every two adjacent chambers 110e arranged horizontally, nor may a first connecting port 11311 be provided between every two adjacent chambers 110e arranged vertically, as long as all chambers 110e are interconnected. For example, in some embodiments, a second connecting port 11321 is provided only between every two adjacent chambers 110e in the lowest layer, while a first connecting port 11311 is provided between every two adjacent chambers 110e in each column arranged vertically.

[0070] It should be noted that the first partition 1131 and the second partition 1132 can also be set at other inclination angles, and the included angle between the first partition 1131 and the second partition 1132 can also be other angles.

[0071] Combination Figure 2 and Figure 3 In some embodiments, the beam assembly 100 further includes a vent pipe 130, which is located on the outside of the beam body 110 and connected to the outer wall of the beam body 110. One end of the vent pipe 130 is connected to the vent 110c, and the other end is set downward.

[0072] Understandably, the vent pipe 130 can guide air to achieve a balance between the air pressure in the liquid storage space 110a and the outside air pressure. When the height of the coolant entering the liquid storage space 110a of the beam 110 reaches the vent 110c, the coolant will be discharged downward through the vent pipe 130. In this way, the coolant can be prevented from splashing in other directions and affecting other components.

[0073] Specifically, in this embodiment, the vent 110c is opened on the side wall of the beam 110, and the vent pipe 130 is a bent pipe. One end of the vent pipe 130 is connected to the outer side wall of the beam 110 and communicates with the vent 110c, while the other end is set downward.

[0074] Understandably, the curved vent pipe 130 can also reduce the speed of the coolant flowing through the vent pipe 130, thereby reducing the spray speed of the coolant.

[0075] like Figure 2 As shown, a vertical plane is defined as the reference plane. The projection of the beam 110 onto the reference plane is the first projection, and the projection of the vent pipe 130 onto the reference plane is the second projection. The top of the first projection is higher than the top of the second projection, and the bottom of the first projection is lower than the bottom of the second projection. In other words, the top of the vent pipe 130 does not extend above the beam 110, and the bottom of the vent pipe 130 does not extend below the beam 110. The vent pipe 130 will not occupy too much vertical space, which helps to save the use of the vehicle's vertical space.

[0076] Combination Figure 2 and Figure 3 In some embodiments, the beam assembly 100 further includes a valve 120; the beam body 110 also has a drain port 110d communicating with the liquid storage space 110a, and the valve 120 is located at the drain port 110d; wherein, the vent 110c is positioned higher than the drain port 110d. Specifically, in this embodiment, the drain port 110d is located on the lower side of the beam body 110. Of course, in other embodiments, the drain port 110d may also be located at the bottom of the beam body 110.

[0077] It is understandable that by setting up a drain port 110d and using valve 120 to open and close the drain port 110d, when a large amount of coolant accumulates in the liquid storage space 110a of the beam body 110, valve 120 can be opened to drain the coolant in the liquid storage space 110a of the beam body 110.

[0078] This utility model also provides a vehicle, including the vehicle frame, liquid cooling plate and first overflow pipe of the above embodiments.

[0079] The vehicle frame itself includes various beams, such as the front bumper beam 400, the rear bumper beam, the left longitudinal beam 200, and the right longitudinal beam 300, while the beam 110 in the beam assembly 100 can be the front bumper beam 400, the rear bumper beam, the left longitudinal beam 200, or the right longitudinal beam 300.

[0080] Specifically, in this embodiment, the left longitudinal beam 200 and the right longitudinal beam 300 are arranged side by side and spaced apart, and the front ends of the left longitudinal beam 200 and the right longitudinal beam 300 are both connected to the front anti-collision beam 400. The beam body 110 in the beam assembly 100 is the right longitudinal beam 300.

[0081] The liquid cooling plate is attached to the battery cell and is used to dissipate heat from the cell. After repeated charging and discharging, the battery cell will expand and squeeze the liquid cooling plate, causing irreversible deformation of the liquid cooling plate and reducing the volume of the coolant flow channel of the liquid cooling plate.

[0082] One end of the first overflow pipe is connected to the coolant channel of the liquid-cooled plate, and the other end is connected to the overflow inlet 110b of the beam 110; wherein, the liquid storage space 110a of the beam 110 is used to receive the coolant overflowing from the coolant channel of the water-cooled plate.

[0083] When the liquid cooling plate is squeezed by the battery cells, causing the coolant in the liquid cooling plate's cooling channels to overflow, the coolant can enter the storage space 110a of the beam 110 through the first overflow pipe. Since a vent 110c is provided on the beam 110, positioned higher than the bottom wall of the storage space 110a, the air pressure in the storage space 110a can be balanced with the external air pressure, allowing the coolant overflowing from the liquid cooling plate's cooling channels to smoothly enter the storage space 110a. In the above embodiment, the vehicle directly utilizes the existing beam 110 in the vehicle frame as a container for the coolant overflowing from the water-cooling plate, reducing the need for other separate containers. This improves upon the problem of requiring an additional expansion tank in related technologies, increases usable space inside the vehicle, and facilitates the arrangement of other components.

[0084] This utility model also provides a vehicle, including the vehicle frame, liquid cooling plate, intermediate container 500, second overflow pipe and third overflow pipe 600 of the above embodiments.

[0085] The vehicle frame itself includes various beams, such as the front bumper beam 400, the rear bumper beam, the left longitudinal beam 200, and the right longitudinal beam 300, while the beam 110 in the beam assembly 100 can be the front bumper beam 400, the rear bumper beam, the left longitudinal beam 200, or the right longitudinal beam 300.

[0086] Specifically, in this embodiment, the left longitudinal beam 200 and the right longitudinal beam 300 are arranged side by side and spaced apart, and the front ends of the left longitudinal beam 200 and the right longitudinal beam 300 are both connected to the front anti-collision beam 400. The beam body 110 in the beam assembly 100 is the right longitudinal beam 300.

[0087] The liquid cooling plate is attached to the battery cell and is used to dissipate heat from the cell. After repeated charging and discharging, the battery cell will expand and squeeze the liquid cooling plate, causing irreversible deformation of the liquid cooling plate and reducing the volume of the coolant flow channel of the liquid cooling plate.

[0088] The two ends of the second overflow pipe are connected to the coolant flow channel of the water-cooled plate and the receiving cavity of the intermediate container 500, respectively. The two ends of the third overflow pipe 600 are connected to the receiving cavity of the intermediate container 500 and the overflow inlet 110b of the beam 110, respectively. The receiving cavity of the intermediate container 500 is used to receive the coolant overflowing from the coolant flow channel of the water-cooled plate, and the liquid storage space 110a of the beam 110 is used to receive the coolant overflowing from the receiving cavity of the intermediate container 500.

[0089] When the coolant in the cooling channel of the liquid-cooled plate overflows due to the pressure of the battery cells, the coolant can enter the receiving cavity of the intermediate container 500 through the second overflow pipe. When the volume of coolant entering the intermediate container 500 reaches its holding limit, the coolant can overflow from the intermediate container 500 and enter the liquid storage space 110a of the beam 110 through the third overflow pipe 600. The intermediate container 500 can be an expansion tank. In this embodiment, the vehicle directly uses the existing beam 110 in the vehicle frame as a container to hold the coolant overflowing from the intermediate container 500. The beam 110 can directly replace the overflow tank in related technologies, eliminating the need for an overflow tank. This improves upon the problem of needing to additionally install an expansion tank and an overflow tank in related technologies, increases the usable space inside the vehicle, and facilitates the arrangement of other parts.
