[0040] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0041] According to the first aspect of the embodiment of the present application, an energy storage mechanism is provided. The following will be combined with Figures 1 to 8 Specifically describe the structure and working principle of the energy storage mechanism.

[0042] According to the energy storage mechanism provided by the embodiment of the present application, the energy storage mechanism is used for a vehicle. The energy storage mechanism includes a battery body, a housing, a circulation loop, a heating member, and an air delivery path. In the embodiment, the housing has a cavity, and the battery body is disposed inside the cavity.

[0043] In an embodiment, a circulation loop is disposed in a housing. The circulation loop is used for circulating a medium and for exchanging heat with a battery body. In the embodiment, a heating member is used to heat the circulation loop, and at least a part of an air delivery path passes through the circulation loop to take away the heat of the circulation loop.

[0044] Thus, according to the energy storage mechanism provided by the embodiment of the present application, when the ambient temperature where the energy storage mechanism is located is relatively low, the heating member will heat the medium inside the circulation loop to increase the temperature of the medium. The heated medium can exchange heat with the battery body, thereby heating the battery body, thereby reducing the resistance increased due to cold inside the battery pack body, improving the current output of the battery pack in a low-temperature environment, and improving the stability of current regulation.

[0045] According to the energy storage mechanism provided by the embodiment of the present application, when the ambient temperature where the energy storage mechanism is located is relatively high, the medium in the circulation loop will also circulate. At this time, the heating member can not heat the medium, so that the medium exchanges heat with the battery body to take away a large amount of heat generated during the operation of the battery body, reducing the influence of heat accumulation on the battery capacity of the battery body, and enabling the energy storage mechanism to resume normal power transmission intensity. In the embodiment, the air delivery path further takes away the heat of the medium in the circulation loop through air flow, which is beneficial to effectively reducing the heat accumulation of the battery body.

[0046] In the embodiment, the circulation loop may have components such as a liquid storage member for storing the medium, and corresponding circulation pipelines communicating with the liquid storage member. A pump may be provided on the rotating pipeline to promote the circulation of the medium in the circulation pipelines.

[0047] In the embodiment, the air delivery path may be, for example, an air duct. The air duct may be, for example, wound around the outside of the liquid storage member, or may directly penetrate into the liquid storage member, which will be described later. In the embodiment, the air in the air duct may be actively provided by, for example, a fan or a blower, or may be supplied by a passive method, which will be specifically described later.

[0048] According to the energy storage mechanism provided by the embodiment of the present application, as mentioned in the above description, the circulation loop may include a circulation pipeline and a liquid storage member. The circulation pipeline may be used for exchanging heat with the battery body. The liquid storage member may communicate with the circulation pipeline. The heating member may communicate with the liquid storage member. As mentioned in the above description, the air delivery path may penetrate through the liquid storage member.

[0049] According to the energy storage mechanism provided by the embodiment of the present application, in the embodiment, the battery body may include, for example, one or more battery modules, and each battery module may include a plurality of single cells.

[0050] In an embodiment, the heating member may be, for example, an existing heater that directly heats the liquid storage member and may be powered by the battery body. In an embodiment, the liquid storage member is substantially a temperature-adjusting water tank, and the medium may be, for example, water or coolant.

[0051] According to the energy storage mechanism provided by the embodiment of the present application, the circulation loop may further include a first pump and a second pump. The first pump may be disposed on the downstream side of the liquid storage member, and the second pump may be disposed on the upstream side of the liquid storage member. The first pump may be used to extract the medium from the liquid storage member, and the second pump may be used to inject the medium into the liquid storage member.

[0052] In an embodiment, the first pump and the second pump may be, for example, micro water pumps and may also be powered by the battery body.

[0053] According to the energy storage mechanism provided by the embodiment of the present application, the air delivery path includes an inlet and an outlet that face each other. The inlet has a wind guiding inclined surface that is inclined relative to the horizontal direction. As an example, the inlet may be located below the liquid storage member, and the outlet may be at the top of the temperature-adjusting water tank. Through the wind guiding inclined surface of the inlet, the wind at the chassis when the vehicle is running can be naturally introduced into the air delivery path, thereby taking away the heat of the medium inside the liquid storage member.

[0054] According to the energy storage mechanism provided by the embodiment of the present application, the housing may further have a plurality of heat dissipation holes. The aforementioned plurality of heat dissipation holes communicate the cavity with the external environment. The heat dissipation holes may be provided, for example, at the bottom of the housing. The energy storage mechanism may further include a shielding member. The shielding member may be, for example, a plate member and may be movably connected to the housing. The shielding member can shield the plurality of heat dissipation holes and open the plurality of heat dissipation holes. When the shielding member opens the aforementioned plurality of heat dissipation holes, it is beneficial to further promote the heat dissipation of the battery body.

[0055] According to the energy storage mechanism provided by the embodiment of the present application, the energy storage mechanism may further include a box body, an energy storage structure, a first terminal, a second terminal, and a third terminal.

[0056] In an embodiment, the box body may have a cavity. The box body may be connected to the housing, for example, on one side in the length direction of the housing. The energy storage structure is disposed in the cavity. The energy storage structure may be, for example, a backup battery. The first terminal may be electrically connected to the battery body. The first terminal may be disposed inside the box body. The second terminal may be electrically connected to the energy storage structure. The second terminal may be disposed inside the box body. In an embodiment, the third terminal may be electrically connected to both the first terminal and the second terminal. The third terminal may be disposed outside the box body.

[0057] In an embodiment, the third terminal may be used for external charging and discharging. Among them, the backup battery may be in a parallel relationship with the battery body. On the one hand, it can prevent the battery body from being overcharged. On the other hand, it can supply power together with the battery body.

[0058] According to the energy storage mechanism provided by the embodiments of the present application, the energy storage structure can be detachably arranged in the box body, so as to facilitate the fixing and removal of the energy storage structure. The energy storage structure is separated from both the first terminal and the second terminal in the box body to improve the electrical insulation performance of the energy storage structure.

[0059] According to the energy storage mechanism provided by the embodiments of the present application, the energy storage mechanism may further include a plurality of strengthening members. The strengthening members can be detachably connected to the box body, and the strengthening members can be detachably connected to the box body. The strengthening members can also be detachably connected to the housing. Thus, the strengthening members can not only protect the energy storage mechanism, but also improve the connection strength between the housing and the box body.

[0060] According to the energy storage mechanism provided by the embodiments of the present application, each strengthening member can straddle the boundary between the box body and the housing, so as to further improve the connection strength and protective measures between the housing and the box body.

[0061] According to the energy storage mechanism provided by the embodiments of the present application, it essentially provides a battery pack that can heat the battery pack (i.e., the battery body, hereinafter referred to as the battery pack body) in a low-temperature environment, thereby reducing the resistance increased due to cold inside the battery pack, reducing the influence of the low-temperature environment on the stability of current output and current regulation, and at the same time enabling the battery pack to reduce the influence of heat accumulation on the battery capacity of the battery pack when the ambient temperature is relatively high and restore the normal power transmission intensity.

[0062] Specifically, a side protection shell 1 and two sealing buckles 2 can be assembled outside the battery pack body 3 (thus forming the upper shell as above, where the side protection shell 1 and the two sealing buckles also form a part of the box body).

[0063] In the embodiment, the two sealing buckles 2 are respectively installed at the top and bottom of the side protection shell 1. A temperature control water tank 4 is installed on one side of the side protection shell 1. A heater 5 is installed on one side of the temperature control water tank 4. A micro water pump 6 and a micro water extraction pump 7 are respectively installed on both sides of the temperature control water tank 4. The water inlet end of the micro water pump 6 and the water delivery end of the micro water extraction pump 7 are both communicated with the inside of the temperature control water tank 4.

[0064] In the embodiment, the water outlet end of the micro water pump 6 is installed with a circulating temperature control pipe 8 (i.e., a circulating pipeline). The circulating temperature control pipe 8 extends into the inside of the side protection shell 1 and is located at the top of the battery pack body 3. The circulating temperature control pipe 8 is in a folded shape. A temperature control plate 9 is installed on the circulating temperature control pipe 8. The temperature control plate 9 is installed inside the side protection shell 1. The folded part of the circulating temperature control pipe 8 is located inside the temperature control plate 9. The temperature control plate 9 is attached to the top of the battery pack body 3.

[0065] In the embodiment, during the daily operation of the battery pack body 3, when the ambient temperature is low, the heater 5 heats the temperature-regulating liquid inside the temperature-regulating water tank 4 to increase the temperature of the temperature-regulating liquid, and then the micro-water pump 6 on one side of the temperature-regulating water tank 4 draws the temperature-regulating liquid from the temperature-regulating water tank 4 and flows along the circulating temperature-regulating tube 8 inside the temperature-regulating plate 9 until it is pumped back into the temperature-regulating water tank 4 by the micro-water pump 7 to achieve circulation, so that the heated temperature-regulating liquid can pass through the circulating temperature-regulating tube 8 and the temperature-regulating plate 9 to heat the battery pack body 3 at the bottom, thereby reducing the resistance inside the battery pack body 3 increased due to the cold, and reducing the stability of the current output and current regulation in the low temperature environment.

[0066] In the embodiment, when the ambient temperature is high, the micro water delivery pump 6 and the micro water extraction pump 7 will also cooperate with each other to transport the temperature-controlled liquid in the temperature-controlled water tank 4 to the circulating temperature-controlled tube 8 for circulation, thereby performing heat exchange with the side protective shell 1 through the circulating temperature-controlled tube 8 and the temperature-controlled plate 9, taking away a large amount of heat generated during the operation of the side protective shell 1, reducing the impact of heat accumulation on the battery capacity of the battery pack body 3, and restoring normal power transmission intensity.

[0067] In the embodiment, a plurality of air ducts 10 (air delivery paths) with openings obliquely facing downward are installed at the bottom of the temperature-control water tank 4. The top ends of the air ducts 10 all penetrate the temperature-control water tank 4 and extend to the top of the temperature-control water tank 4, so that during the operation of the automobile, the air flow blown into the battery pack installation position through the air holes of the chassis can pass through the temperature-control water tank 4 through each air duct 10, thereby cooling the temperature-control water tank 4 itself, thereby ensuring the cooling effect of the temperature-control liquid inside the temperature-control water tank 4. By arranging a micro-water delivery pump 6 and a micro-water pump 7 to cooperate with each other to transport the temperature-control liquid, it is possible to prevent a single micro-water delivery pump 6 or a micro-water pump 7 from being insufficiently powered, thereby affecting the transport speed of the temperature-control liquid in the circulating temperature-control pipe 8, thereby affecting the temperature-control effect of the side protective shell 1. Two protective shells 29 are installed on one side of the side protective shell 1, and the micro-water delivery pump 6 and the micro-water pump 7 are respectively located inside the two protective shells 29.

[0068] In the embodiment, a battery box 11 is installed on one side of the side protective shell 1, and the position of the battery box 11 is consistent with the terminal position of the battery pack body 3. The terminals of the battery pack body 3 are located inside the battery box 11. Battery buckle plates 12 are installed on the top and bottom of the battery box 11. A battery accommodating compartment 13 is installed inside the battery box 11, and a spare battery 14 is placed inside the battery accommodating compartment 13.

[0069] In an embodiment, the terminals of the battery pack body 3 and the terminals of the spare battery 14 are respectively plugged with a first socket 15 (i.e., the first terminal) and a second socket 16 (i.e., the second terminal). An external terminal 17 (i.e., the third terminal) facing outward is installed on one side of the battery box 11. The first socket 15, the second socket 16, and the external terminal 17 are connected to each other through a power transmission line 18. In this way, the spare battery can be connected in parallel with the battery body.

[0070] In an embodiment, the first socket 15, the second socket 16, and the external terminal 17 are fastened by fastening bolts 19. A heat preservation sleeve 20 is assembled inside the battery accommodation bin 13. The spare battery 14 is located inside the heat preservation sleeve 20. By providing the spare battery 14, the battery pack body 3 and the spare battery 14 are connected to each other through the first socket 15, the second socket 16, the power transmission line 18, and the external terminal 17. The first socket 15, the second socket 16, the power transmission line 18, and the external terminal 17 form a transfer structure. The battery pack body 3 and the spare battery 14 supply power to the vehicle through the external terminal 17.

[0071] In an embodiment, during the charging and discharging process of the vehicle, when the charging and discharging of the battery pack body 3 reaches a threshold value, the charging and discharging is switched to the spare battery 14, thereby preventing the battery pack body 3 from being over-discharged or over-charged, which may affect the service life and operation safety of the battery pack body 3. The first socket 15 and the second socket 16 are respectively locked with the side protection shell 1 and the battery accommodation bin 13 through the fastening bolts 19, and the external terminal 17 is locked with the battery box 11 through the fastening bolts 19, so that the transfer structure can be quickly disassembled, thereby facilitating the replacement of the spare battery 14. At the same time, it can prevent the first socket 15 and the second socket 16 from loosening during the operation of the vehicle, which may affect the stability of the output current.

[0072] In an embodiment, by providing the heat preservation sleeve 20, the heat preservation sleeve 20 can provide heat preservation protection for the spare battery 14, preventing the output current of the spare battery 14 from being difficult to reach the specified current intensity in a low-temperature environment. Two symmetrically arranged positioning pins 21 are slidably installed at the bottom of the spare battery 14. A jack adapted to the positioning pins 21 is provided on the inner wall of the heat preservation sleeve 20. When replacing the spare battery 14, the battery buckle plate 12 at the bottom can be opened and the positioning pins 21 can be slid out of the jacks to disconnect the connection between the second socket 16 and the spare battery 14. Then, the spare battery 14 can be removed for replacement, and the positioning pins 21 at the bottom of the new spare battery 14 can be reinserted into the jacks to assemble the spare battery 14 inside the heat preservation sleeve 20. Subsequently, the battery buckle plate 12 can be reassembled at the bottom of the battery box 11 to complete the replacement of the spare battery 14.

[0073] In the embodiment, a plurality of suspension sleeves 22 are installed at the bottom of the sealing buckle plate 2 located below, and a reinforcing slide rod 23 is slidably installed inside the suspension sleeves 22. A plurality of insert tubes 24 are installed at the bottom of the battery buckle plate 12 located below (the insert tubes 24 are fixedly installed and provide grooves for inserting the reinforcing slide rods 23). The plurality of insert tubes 24 correspond one by one to the plurality of reinforcing slide rods 23 and are adapted to each other. A plurality of positioning blocks 25 are installed at the bottom of the sealing buckle plate 2 through positioning bolts 26, and the plurality of positioning blocks 25 are respectively located at one end of the plurality of reinforcing slide rods 23.

[0074] In the embodiment, by providing the reinforcing slide bar 23, after the backup battery 14 is assembled inside the battery box 11, multiple reinforcing slide bars 23 are slid, one end of which is respectively inserted into the inside of multiple insert tubes 24, and the positioning block 25 is assembled at the other end through the positioning bolt 26, so that the positioning block 25 and the insert tube 24 cooperate with each other to limit the reinforcing slide bar 23, so that the reinforcing slide bar 23 is suspended at the bottom of the battery box 11 and the battery buckle plate 12, thereby protecting the battery buckle plate 12, improving the impact resistance of the battery buckle plate 12, and ensuring the stability of the operation of the backup battery 14.

[0075] In the embodiment, the bottom of the sealing plate 2 located at the bottom is provided with a plurality of evenly distributed heat dissipation holes 201, and the plurality of heat dissipation holes 201 are all located at the bottom of the battery pack body 3. A sealing slide 27 is slidably mounted at the bottom of the sealing plate 2, and the position of the sealing slide 27 corresponds to the position of the plurality of heat dissipation holes 201. An electric push rod 28 is mounted at the bottom of the sealing plate 2, and the output end of the electric push rod 28 (which can also be driven by the battery body) is drivingly connected to one side of the sealing slide 27. The sealing slide 27 enables, in a high temperature environment, in addition to using the micro water delivery pump 6 and the micro water pump 7 to circulate the temperature regulating liquid to cool the battery pack body 3, the electric push rod 28 will drive the sealing slide 27 to slide at the bottom of the sealing plate 2, exposing each heat dissipation hole 201, so that the external airflow can dissipate heat and cool the internal battery pack body 3 through the plurality of heat dissipation holes 201, thereby improving the cooling efficiency and ensuring the stable operation of the battery pack body 3.
