[0029] The following will describe in detail a specific embodiment of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the description of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0031] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.
[0032] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.
[0033] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.
[0034] As attached Figure 1 As shown, the automobile anti-roll bar structure proposed by the utility model includes a main body 10, the main body 10 includes a cavity 101, and a first connecting pipe 11 and a second connecting pipe 12 connected to the cavity 101, the first connecting pipe 11 is connected to a liquid storage mechanism 31 on a vehicle body 30 through a pipe 311 to connect the liquid storage mechanism 31 with the cavity 101, the liquid storage mechanism 31 is used to connect a cooling plate of a power battery, the cavity 101 cooperates with the liquid storage mechanism 31 to accommodate coolant overflowing from the cooling plate, and the second connecting pipe 12 can be connected to the outside to discharge the coolant in the cavity 101.
[0035] The cooling plate usually includes a flow channel through which the coolant can circulate, and a liquid inlet and a liquid outlet connected to the flow channel. The coolant enters the flow channel through the liquid inlet and flows out of the flow channel through the liquid outlet. The cooling plate is usually arranged on one side of the power battery and is configured to directly or indirectly contact the power battery for heating or cooling the power battery. When the temperature of the coolant circulating in the cooling plate is higher than the temperature of the power battery, the cooling plate can heat the power battery. When the temperature of the coolant circulating in the cooling plate is lower than the temperature of the power battery, the cooling plate can cool the power battery.
[0036] After the car leaves the factory, the amount of coolant added to the interior of the car body 30 is fixed. After the power battery has been used for a long time, the battery will swell to varying degrees. The swollen power battery will squeeze the cooling plate, causing the cooling plate to deform. The deformation will cause the flow channel volume of the cooling plate to decrease, so that the coolant inside the cooling plate will partially overflow. The liquid storage mechanism 31 is provided to accommodate the overflowed coolant. Due to the spatial size of the car body 30, the capacity of the liquid storage mechanism 31 is limited. When the amount of coolant overflowing from the cooling plate is greater than the capacity of the liquid storage mechanism 31, the liquid storage mechanism 31 cannot continue to store liquid, affecting the normal use of the car.
[0037] If a plurality of liquid storage mechanisms 31 are arranged inside the vehicle body, the space occupied is large and additional installation components are required to realize the installation of the liquid storage mechanisms 31 . The cost of the components invested is high and for some vehicle models, the vehicle body 30 does not have enough layout space.
[0038] The utility model provides a cavity 101 capable of storing liquid on the main body 10, so that the cavity 101 is connected with the liquid storage mechanism 31 through the first connecting pipe 11, which can increase the capacity of the liquid storage mechanism 31. When the amount of coolant overflowing from the cooling plate is greater than the capacity of the liquid storage mechanism 31, part of the coolant can enter the cavity 101 of the main body 10 from the liquid storage mechanism 31 through the first connecting pipe 11 and the pipe 311 connected thereto. Since the main body 10 only plays a role when the car is turning, the increase of coolant inside the main body 10 and the change of its own weight will not have much impact on its function. By integrating the liquid storage function into the main body 10, there is no need to provide an additional liquid storage tank on the body except for the liquid storage mechanism 31, which reduces the occupation of the body space and is conducive to the arrangement of the body structure. The structure is simple, the investment amount and cost of installation components related to the liquid storage tank are reduced, the body structure is streamlined, and the development cost is reduced.
[0039] As an example, the vehicle body 30 in the present invention refers to a tower structure of a vehicle, and both ends of the main body 10 are used to connect with the tower to increase the structural stability of the body-in-white.
[0040] As an example, the main body 10 is cylindrical, and can certainly be set to other shapes. Those skilled in the art can set the shape of the main body 10 according to actual needs.
[0041] As an example, the cavity 101 of the main body 10 is a cylindrical cavity, which can be configured to match the cylindrical shape of the main body 10 and set the capacity of the cavity 101 as large as possible to increase the liquid storage capacity of the cavity 101. It can be understood that the capacity of the cavity 101 can be set according to the amount of coolant discharged during the maintenance of the automobile, and those skilled in the art can set the capacity of the cavity 101 according to actual needs.
[0042] As an example, the attached Figure 3 As shown, the radial dimension of the cavity 101 gradually decreases from both ends of the length direction of the main body 10 to the middle position of the main body 10. More specifically, the radial dimension of the cavity 101 gradually decreases from the end close to the first connecting pipe 11 to the middle of the main body 10, and gradually increases from the middle of the main body 10 to the end close to the second connecting pipe 12. Such an arrangement can make the middle position of the main body 10 have good structural strength, so that the main body 10 has good stability.
[0043] As an example, the first connecting pipe 11 is protruded from one end of the main body 10 along the length direction, and the second connecting pipe 12 is protruded from the other end of the main body 10 along the length direction, that is, the end of the main body 10 away from the first connecting pipe 11. Optionally, the first connecting pipe 11 and the second connecting pipe 12 are coaxially arranged on the main body 10.
[0044] As another example, the first connecting pipe 11 and the second connecting pipe 12 are protruded from the same end of the main body 10 along the length direction.
[0045] It is understandable that the first connecting pipe 11 and the second connecting pipe 12 can also be arranged at other positions of the main body 10. The above examples are only some preferred solutions, but it does not mean that the first connecting pipe 11 and the second connecting pipe 12 can only be arranged at the above positions.
[0046] Optionally, the first connecting pipe 11 and the main body 10 are connected as one body by welding.
[0047] Optionally, the second connecting pipe 12 and the main body 10 are connected as one body by welding.

When the sealing member 13 is installed on the second connecting pipe 12, the second connecting pipe 12 is in a closed state, that is, the second connecting pipe 12 and the cavity 101 are not connected to the outside, and the coolant is stored in the cavity 101. When the sealing member 13 is removed from the second connecting pipe 12, the second connecting pipe 12 is in an open state, the second connecting pipe 12 and the cavity 101 are connected to the outside, and the coolant in the cavity 101 can be discharged through the second connecting pipe 12.
[0049] As an example, in conjunction with the attached Figure 1 and attached Figure 4 The sealing member 13 includes a connecting member 131 and a blocking member 132. The connecting member 131 and the blocking member 132 are connected along the length direction. The connecting member 131 is installed inside the second connecting pipe 12 and is detachably connected to the second connecting pipe 12. The radial dimension of the blocking member 132 is larger than the radial dimension of the connecting member 131, and the radial dimension of the blocking member 132 is slightly larger than the inner pipe diameter of the second connecting pipe 12. In this way, the blocking member 132 can be interference fit with the second connecting pipe 12. The blocking member 132 is at least partially installed in the second connecting pipe 12 to cooperate with the connecting member 131 to seal the second connecting pipe 12.
[0050] Optionally, the connecting piece 131 is threadedly connected to the second connecting pipe 12, which has a simple structure and is easy to assemble and disassemble.
[0051] Optional, as attached Figure 4 As shown, a plurality of grooves 1321 are provided on the radially outermost surface of the sealing member 132, and the grooves 1321 are used to reduce the contact area between the sealing member 132 and the inner tube wall of the second connecting pipe 12, which can not only ensure the sealing effect of the sealing member 132 on the second connecting pipe 12, but also facilitate the removal of the sealing member 132 from the second connecting pipe 12, and the operation is simple and convenient.
[0052] Optionally, a blocking member 133 is provided at one end of the sealing member 132 away from the connecting member 131, and the radial dimension of the blocking member 133 is greater than the radial dimension of the sealing member 132. When the sealing member 132 is connected to the second connecting pipe 12, the sealing member 132 is completely installed inside the second connecting pipe 12, and the blocking member 133 is in contact with the end of the second connecting pipe 12 away from the main body 10. The blocking member 133 can cooperate with the connecting member 131 and the sealing member 132 to achieve sealing of the second connecting pipe 12 and avoid leakage.
[0053] Optional, as attached Figure 4 As shown, the sealing member 13 further includes a holding member 134 , which is located at one end of the blocking member 133 away from the blocking member 132 .
