As described in the background art, with the rapid development of new energy vehicles, requirements on the performance and safety of power batteries of vehicles are higher and higher, chemical performance of the batteries is greatly reduced at a low temperature, and even the batteries cannot be charged or discharged due to a low temperature. For example, in winter in the north, outdoor temperature is basically below zero, outdoor temperature is lower at night, if the thermal insulation performance of a power battery of an electric automobile is poor, the temperature of the power battery can be lowered to a very low level after the power battery is placed outdoors overnight, when the temperature of the power battery is lowered to a certain degree, the power battery cannot be charged or discharged, meanwhile, the electrochemical activity of the battery can be influenced in a low-temperature environment, the performance of the battery can be greatly reduced, and therefore the thermal insulation of the power battery is particularly important and is a difficult point.

At present, the main heat preservation measures of the power battery are active heat preservation and passive heat preservation, wherein the active heat preservation is that the battery is heated through a liquid heating device or a heating film, and the passive heat preservation is that heat preservation cotton is attached to the inside or the outside of the battery, so that the heat preservation effect is achieved. Although the prior art has a plurality of mature technologies which can reduce the heat loss of the battery and improve the heat preservation effect, the actual effect is not ideal.

In view of the above, referring to fig. 1 to 5, the present embodiment provides a battery pack frame 100, a battery pack 1000 and an automobile, which can effectively solve the above-mentioned technical problems, reduce the heat loss of the battery, and improve the heat preservation effect.

Referring to fig. 1, fig. 1 illustrates an automobile provided in the present embodiment, which includes an automobile body 2000 and a battery pack 1000; the battery pack 1000 is mounted to the vehicle body 2000. The vehicle body 2000 may be an electric vehicle, a conventional oil vehicle, a hybrid vehicle, or the like. The battery pack 1000 may be used to provide power to the entire vehicle or to provide power to external devices.

Referring to fig. 2 and 3, the battery pack 1000 includes a battery module 300 and a battery pack frame 100; the battery module 300 is mounted to the mounting body 10 of the battery pack frame 100. Specifically, the battery pack frame 100 is mounted on the vehicle body 2000, and in the present embodiment, the battery pack 1000 further includes a cover 200, the cover 200 is mounted on the mounting body 10, and the battery module 300 is covered between the cover 200 and the mounting body 10. The battery module 300 can be effectively protected by the cooperation of the pack frame 100 and the cover 200. Meanwhile, in order to facilitate the hoisting of the battery pack 1000, a plurality of hoisting prepared holes 101 are arranged around the battery pack frame 100.

Generally, in order to improve the sealing and thermal insulation effects, in the embodiment, referring to fig. 3, the battery pack 1000 further includes a mounting pad 400, and the mounting pad 400 is disposed at the mounting joint of the cover body 200 and the mounting body 10. In fig. 3, the battery pack frame 100 is similar to a box structure, and has a ring structure protruding upward from the periphery thereof, and similarly, the cover 200 may be designed as a box structure, and has a ring structure protruding downward from the periphery thereof, and in order to optimize the heat-insulating sealing performance, the mounting pad 400 is specifically designed as a ring structure, so as to effectively seal and insulate each combination position. The mounting pad 400 may be made of soft materials such as rubber or silica gel, or hard materials such as polyvinyl chloride, hard plastic, polyurethane, etc.

Referring to fig. 3 to 5, the battery pack frame 100 will be described in detail.

The battery pack frame 100 comprises a mounting body 10, and a fixed edge beam 20 and a split edge beam 30 which are arranged at the edge of the mounting body 10; the mounting body 10 is used to mount the battery module 300; the fixed edge beam 20 is fixedly connected with the edge of the installation body 10, and the split edge beam 30 is fixedly installed on the fixed edge beam 20 through the heat insulation pad 40. The heat conduction quantity of the fixed edge beam 20 can be reduced by the heat insulation pad 40, so that the heat loss of the battery can be reduced on the whole, and the heat insulation effect is improved.

It can be understood that, in a low-temperature environment, the heat dissipation of the battery pack 1000 is mainly that the heat in the battery pack 1000 is dissipated from the battery pack 1000 to the external low-temperature environment through heat conduction, heat convection and the like. In general, the prior art designs the boundary beam as an integral structure which easily conducts heat in the battery pack 1000 to the outside, and based on this, in this embodiment, the boundary beam is configured as a non-integral structure, that is, the boundary beam includes the fixed boundary beam 20 and the split boundary beam 30, and the heat insulating pad 40 is disposed at the joint position of the fixed boundary beam 20 and the split boundary beam 30 to insulate heat conduction.

The installation body 10, fixed boundary beam 20 and split type boundary beam 30 are generally metal materials to Al6061 is the example, and its coefficient of heat conductivity is 155W/(mk) under normal atmospheric temperature, changes the boundary beam into split type by the integral type, separates through heat insulating mattress 40 between fixed boundary beam 20 and the split type boundary beam 30, can block the heat and transmit split type boundary beam 30, the route that scatters and disappears to the external environment again from the installation body 10, plays fine heat preservation effect. The heat insulation pad 40 can be made of a high thermal resistance material (the thermal conductivity is generally 0.03W/(mk) -0.2W/(mk), and the specific thermal conductivity can be selected according to the actual situation), and the thermal conductivity of the high thermal resistance material is relatively low (for example, polyvinyl chloride, hard plastic, polyurethane, etc.). Through heat insulating mattress 40, can prevent to a great extent that the heat in the battery package 1000 from transmitting to split type boundary beam 30 through fixed boundary beam 20 on, reach the effect that reduces the heat and scatter and disappear, can further improve the heat preservation effect of battery package 1000 under the low temperature environment.

Of course, the material of the installation body 10, the fixed edge beam 20 and the split edge beam 30 may be the same or different, for example, the installation body 10 is made of Al6061, and the fixed edge beam 20 and the split edge beam 30 are made of stainless steel. Generally, the specific material selection is determined according to design requirements (such as structural strength, total weight, and the like).

In order to reduce the contact area and optimize the heat preservation effect, in this embodiment, the split type edge beam 30 includes a body 31 and a fixing structure 32 protruding from one end of the body 31, and the fixing structure 32 is fixed to the fixed edge beam 20 through a heat insulation pad 40. The fixing structure 32 is provided protruding from the body 31 and can be designed relatively small in size to reduce the contact area.

Meanwhile, referring to fig. 3-5, in the present embodiment, the fixing edge beam 20 is provided with an installation notch 21, and the fixing structure 32 is embedded in the installation notch 21. Therefore, the installation of the fixing structure 32 can be avoided, and meanwhile, the fixing structure 32 can be accommodated, so that the appearance contour consistency is good.

In this embodiment, referring to fig. 2 to 4, the body 31 is spaced from the mounting body 10. Through the separation of the two, the split type boundary beam 30 can also realize the efficacy of an anti-collision beam, and the separation distance can be specifically determined according to the actual situation. When the body 31 is mounted on the vehicle body 2000, the mounting body 10 and the fixed side rail 20 are suspended. Alternatively, the body 31 is mounted to the vehicle body 2000, and the mounting body 10 and the fixed side sill 20 are supported on the vehicle body 2000 by a heat insulating material. Generally, in order to further reduce contact heat conduction and improve heat preservation performance, the entire outer circumference of the battery pack 1000 may be coated with a heat insulating material.

Through the interval setting, on the one hand, can avoid the heat to transmit to body 31 from installation body 10 on, cause too much heat to scatter and disappear, can improve the thermal insulation performance of battery package 1000 to a certain extent.

On the other hand, when the battery pack 1000 is impacted by other object side surfaces, since a certain distance is reserved between the body 31 and the mounting body 10, the body 31 can absorb the energy of impact of foreign matters, so as to achieve the purpose of energy absorption, and prevent the parts in the battery pack 1000 from being extruded due to impact, for example, the situation that the electric core, the liquid cooling plate and the like of the battery module 300 are extruded to influence the performance or cause safety problems after deformation can be avoided, and the safety can be effectively improved as a whole.

In this embodiment, a side surface of the body 31 close to the mounting body 10 is a plane, and a side surface of the mounting body 10 close to the body 31 is also a plane, and the two planes are parallel. Of course, it is not excluded that in certain embodiments, both surfaces are curved or irregular. In addition, in some cases, the same insulating material as the insulating mat 40 may be provided at spaced locations.

In order to reduce the weight and improve the energy absorption effect, the fixed edge beam 20 and the split edge beam 30 may be hollow, for example, the split edge beam 30 may be a hollow profile.

Optionally, in a certain example, the split type edge beam 30 (the fixing structure 32) is only connected to the thermal insulation pad 40, for example, one side of the thermal insulation pad 40 is fixedly connected to the fixed edge beam 20, and the other side of the thermal insulation pad 40 is fixedly connected to the split type edge beam 30 (the fixing structure 32), in other words, the split type edge beam 30 (the fixing structure 32) does not contact with the fixed edge beam 20, so that the thermal insulation effect is better. Of course, the split-type edge beam 30 (fixing structure 32) may be mounted to the fixing edge beam 20 through other structures, and the heat insulation pad 40 may be disposed between the fixing edge beam 20 and the fixing structure 20 for heat insulation, for example, in this embodiment, the battery pack frame 100 further includes a fastener 50, the heat insulation pad 40 is sandwiched between the fixing edge beam 20 and the fixing structure 32, and the fastener 50 is used for fixing the fixing structure 32 to the fixing edge beam 20 and clamping the heat insulation pad 40.

In this embodiment, the fastener 50 may be a bolt, a screw, or the like. Of course, other connection manners, such as a structure of a lock catch, etc., may be adopted as long as the connection effect can be achieved. Generally, the fastening member 50 may be a standard member of the prior art, but, in order to further improve the heat insulation effect, the fastening member 50 may be made of the same material as the heat insulation pad 40.

Referring to fig. 5 in combination with fig. 3 and 4, in the present embodiment, the fixing structure 32 is provided with a first mounting hole 33, the heat insulation pad 40 is provided with a second mounting hole 41, the fixing edge beam 20 is provided with a third mounting hole 22, and the fastening member 50 is configured to pass through the first mounting hole 33 and the second mounting hole 41 in sequence and then be mounted and fixed with the third mounting hole 22. The installation of the split type boundary beam 30 and the heat insulation pad 40 can be completed by sequentially penetrating and arranging, and the heat insulation pad 40 is clamped. In one example, the fastener 50 may be sequentially inserted through the third mounting hole 22 and the second mounting hole 41 and then fixed to the first mounting hole 33. Alternatively, in one example, the insulation blanket 40 may not have a through hole, and the fastener 50 may pass through the first mounting hole 33 of the fixing structure 32 and then be fixedly mounted to the third mounting hole 22 of the fixed edge rail 20, so as to clamp the insulation blanket 40 between the fixing structure 32 and the fixed edge rail 20.

In the present embodiment, the number of the first mounting holes 33, the second mounting holes 41, and the third mounting holes 22 is two, and the number of the fasteners 50 is two, for the case of assembling one of the fixing structures 32. Of course, the number and size of the holes are determined according to actual conditions in specific implementation.

Meanwhile, in order to more stably mount the split type edge beam 30 to the fixed edge beam 20, in the present embodiment, the fixed edge beam 20 includes a first fixed edge beam 201 and a second fixed edge beam 202 which are spaced apart from each other; the insulation pad 40 includes a first insulation pad 401 and a second insulation pad 402. The two ends of the body 31 are both provided with a fixing structure 32 in a protruding manner, and the two fixing structures 32 at the two ends of the body 31 are respectively fixed to the first fixing edge beam 201 and the second fixing edge beam 202 through a first heat insulation pad 401 and a second heat insulation pad 402.

In this embodiment, the fixing structures 32 are disposed at two ends of the main body 31, and each fixing structure 32 corresponds to an independently designed heat insulation pad 40. Of course, in other embodiments, a longer insulation blanket 40 may be used to cover both of the securing structures 32, such that both securing structures 32 are secured to the fixed sill 20 by the same insulation blanket 40.

Specifically, the installation body 10 is a rectangular structure, at least one side of the installation body 10 is distributed with a first fixed boundary beam 201, a split boundary beam 30 and a second fixed boundary beam 202, and the split boundary beam 30 is located at the middle position of one side of the installation body 10. Specifically, in this embodiment, the first fixed side beam 201, the split side beam 30, and the second fixed side beam 202 are distributed on two opposite sides of the installation body 10. And, both sides are the symmetrical design, i.e. the structure of both sides is exactly the same.

It can be understood that the first fixed boundary beam 201 and the second fixed boundary beam 202 present a symmetrical distribution on both sides of the split type boundary beam 30, so that the hoisting prepared holes 101 can be distributed on the first fixed boundary beam 201 and the second fixed boundary beam 202, and the existence of the split type boundary beam 30 does not substantially affect the setting and the overall structural strength of the hoisting prepared holes 101.

Of course, the hoisting prepared holes 101 may be distributed only at the edge of the installation body 10, or the installation body 10, the first fixed boundary beam 201 and the second fixed boundary beam 202 may be distributed with the hoisting prepared holes 101. Based on this, at least one of the installation body 10, the first fixed side beam 201, and the second fixed side beam 202 may be provided with the hoisting prepared hole 101.

In order to facilitate installation of the split type edge beam 30, in the present embodiment, in a direction from the center of the installation body 10 to the edge of the installation body 10 (i.e., an arrow a direction), a distance between the first fixed edge beam 201 and the second fixed edge beam 202 is gradually increased, and a width of the body 31 is gradually increased, in combination with fig. 3 and 4. It will be appreciated that the body 31 is similar to a trapezoidal structure, and a trapezoidal groove is similarly formed between the first and second fixed edge beams 201 and 202, so that the split edge beam 30 can be inserted between the first and second fixed edge beams 201 and 202 from the side in the direction of arrow B, thereby facilitating installation thereof. It will be appreciated that the direction of arrow a is opposite to the direction of arrow B.
