Description

Technical Field

[0001] The present invention relates to the technical field of battery modules, and in particular to a modular portable energy storage battery module. Background Art

[0002] With the rapid development of the battery industry, cost optimization, rapid assembly and simple structure have become the development trend of the industry. Today's power battery industry mostly arranges multiple battery modules in parallel in a row, and then fixes the battery modules to form battery modules. The battery modules can make the entire device modular. When a battery module loses its effectiveness, it only needs to be replaced to continue to be used. At the same time, the battery module is highly portable and can be conveniently moved to various locations for use.

[0003] At present, the battery modules with portable energy storage characteristics still have the following deficiencies when used: 1. The charging and discharging technology of the battery module is developing rapidly, and the requirements for the heat dissipation performance of the battery module are gradually increasing. The existing battery module is usually composed of one or several rows of battery modules arranged and fixed in the outer shell. The battery module itself will generate a lot of heat when it is charged and discharged at high power, and the battery module structure in the prior art has the defect of insufficient heat dissipation, which limits the performance of the battery module; 2. The temperature has a great influence on the battery module. For example, in the cold winter, the charging and discharging and storage performance of the battery module are reduced, and the life of the battery module is related to the number of charging and discharging cycles. The battery module in the prior art does not have the disadvantages of heating and heat preservation or the heat preservation effect is poor: 3. The battery module is composed of multiple battery modules, and the weight of the battery module itself is heavy. The existing method of replacing the battery module is to manually control the battery module in and out of the outer shell by directly loading, which has the defect of poor convenience in replacing the battery module.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1

[0042] See also Figure 1-8A modular portable energy storage battery module includes a base 1 and a plurality of battery modules 2. The base 1 serves to load the battery module. The plurality of battery modules 2 are combined on the base 1 to form a battery module. In this embodiment, the technical problems to be solved by the battery module are how to ensure the heat dissipation performance of the entire module during high-power charging and discharging of the battery module 2, how to ensure the performance of the battery module 2 in a low-temperature environment, and how to improve the convenience of replacing the battery module 2.

[0043] Specifically, a cylinder frame 3 is rotatably connected above the base 1. The cylinder frame 3 is in a horizontal state and open at both ends. The outer peripheral wall of the cylinder frame 3 is penetrated and radially slidably connected with a plurality of circumferentially uniformly distributed positioning square tubes 4. In the specific implementation, it is preferred that the outer peripheral wall of the cylinder frame 3 is penetrated with a square opening 33 for making way for the positioning square tube 4, and limiting sleeves 42 are welded on the tops of both sides of the positioning square tube 4. The outer peripheral wall of the cylinder frame 3 is welded with guide rods 34 located on both sides of the square opening 33 and slidingly matched with the limiting sleeves 42. The inner peripheral wall of the cylinder frame 3 is welded with sealing plates 35 located at both ends of the positioning square tube 4, and a socket 351 is penetrated on the sealing plate 35. One end of the bottom plate of the positioning square tube 4 close to the axis of the cylinder frame 3 is penetrated with a through hole 43 connected to the socket 351 by a pin. After the pin is pulled out, the positioning square tube 4 slides in the square opening 33, and a sealing strip can be bonded to the inner peripheral wall of the square opening 33 when in use. The positioning square tube 4 is used to fix the battery module 2. One positioning square tube 4 is corresponding to one battery module 2. Several battery modules 2 are in a state of surrounding the barrel frame 3. When the positioning square tube 4 slides back and forth, the battery module 2 will switch inside and outside the barrel frame 3. Among them, ventilation windows 41 are opened on both sides of the positioning square tube 4. The function of the ventilation windows 41 is to discharge the heat generated by the battery module 2 to the outside.

[0044] Furthermore, a plurality of circumferentially uniformly distributed groove covers 5 are radially slidably connected to the outer peripheral wall of the cylinder frame 3, and the main view projection of the groove covers 5 is a fan-shaped structure. The plurality of groove covers 5 and the plurality of positioning square tubes 4 are opposite to each other, that is, the positioning square tube 4 is located in the groove covers 5. In the present embodiment, the number of the groove covers 5 and the positioning square tubes 4 are both six. When the plurality of groove covers 5 move to the extreme position in the axial direction of the cylinder frame 3 and the positioning square tubes 4 move to the extreme position in the direction away from the axial direction of the cylinder frame 3, the space where the plurality of battery modules 2 are located is a closed heat-insulating space, that is, the adjacent groove covers 5 are in a fitted and sealed state, and the groove covers 5 and the outer peripheral wall of the cylinder frame 3 are fitted. In the specific implementation, a sealing strip can be adhered to the outer periphery of the groove covers 5, and then the bottom of the positioning square tube 4 is sealed to seal the cylinder frame 3, so that the battery module 2 is enclosed in the above-mentioned closed space. At this time, the battery module has moisture-proof and waterproof properties. On the contrary, when the plurality of grooved covers 5 move in the reverse direction, each battery module 2 can directly dissipate heat to the outside through the ventilation window 41, and the contact surface between the battery module 2 and the outside air is determined by the size of the ventilation window 41. This arrangement enables the battery module to ensure heat dissipation performance during high-power charging and discharging.

[0045] A heat sink 6 is provided on the side of the positioning square tube 4 opposite to the axis of the cylinder frame 3. The function of the heat sink 6 is to introduce the heat generated by the battery module 2 into the cylinder frame 3, and the heat is discharged from the openings at both ends of the cylinder frame 3. Heat sink fins can be provided on the side of the heat sink 6 facing the cylinder frame 3 to improve the heat dissipation performance. When in use, one end face of the battery module 2 is fitted with the heat sink 6.

[0046] In this embodiment, a sleeve 7 is sleeved at one end of the cylinder frame 3, and the sleeve 7 is used to block one end of the cylinder frame 3. A vent 71 is opened in the middle of the sleeve 7, and a slide 72 is provided on one side of the sleeve 7. A support shaft 8 coaxial with the cylinder frame 3 is penetrated and slidably connected in the middle of the slide 72. A small cover 9 and a large cover 101 are fixedly sleeved on the support shaft 8, which are respectively sealed with the vent 71 and the other end of the cylinder frame 3. The function of the small cover 9 is to block the vent 71, and the function of the large cover 101 is to block the vent. At the other end of the cylinder frame 3, when the small cover 9 opens and closes the vent 71, the large cover 101 opens and closes the other end of the cylinder frame 3 accordingly. A heating tube 102 is fixedly arranged on the large cover 101 on one side facing the inside of the cylinder frame 3. The heating tube 102 uses a common resistance heating wire structure. After the cylinder frame 3 is blocked, power is supplied to the heating tube 102, and the heating tube 102 generates heat, and the temperature inside the cylinder frame 3 rises. At this time, the heat sink 6 will heat the inner cavity where the battery module 2 is located, so that the battery module 2 is in an environment that does not affect its performance. Before using this battery module, close the large cover 101 and the small cover 9 to heat and keep the battery module 2 warm. When in use, when the heat dissipated by the battery module 2 reaches a certain temperature, open the large cover 101 and the small cover 9, so that the heat sink 6 dissipates heat outward. The heating tube 102 is electrically connected to the battery module 2, and the battery module 2 supplies power to the heating tube 102.

[0047] Furthermore, a guide sleeve 721 detachably connected to the support shaft 8 is welded on the slide 72. In specific implementation, a resistance-enhancing rubber sleeve can be sleeved in the guide sleeve 721, and a damping sliding connection is achieved through the resistance-enhancing rubber sleeve and the support shaft 8. In other words, the support shaft 8 can be pulled out of the guide sleeve 721 and separated from the barrel frame 3. A handle 1011 is welded on the other side of the large cover 101. The handle 1011 is a hand-held component. After the positioning square tube 4 enters the barrel frame 3, an opening on it faces the large cover 101. The positioning square tube 4 and the battery module 2 therein are detachably connected. When a positioning square tube 4 moves and drives the battery module 2 to enter the barrel frame 3, the battery module 2 and the positioning square tube 4 can be docked and separated from the other end of the barrel frame 3. When installing and removing the battery module 2, the positioning square tube 4 can be assisted by controlling the rotation of the barrel frame 3 to slide relative to the barrel frame 3 using gravity. This makes the disassembly and assembly of the battery module 2 more convenient and labor-saving.

[0048] In this embodiment, a screw 103 is screwed through one end of the positioning square tube 4 away from the axis of the barrel frame 3, one end of the screw 103 is rotatably connected to a pressure plate 1032 located in the positioning square tube 4, and the other end of the screw 103 is fixedly connected to a driving head 1031, which is a hexagonal head structure. A clearance hole 51 opposite to the driving head 1031 is provided on the side wall of the groove cover 5 opposite to the positioning square tube 4. After the hexagonal wrench is inserted from the clearance hole 51, it can be docked with the driving head 1031, and then the driving head 1031 is screwed. At this time, the pressure plate 1032 can press the battery module 2 in the positioning square tube 4 to achieve the fastening installation of the battery module 2. The clearance hole 51 is detachably connected with a plug 104, which can be a rubber plug plugged with the clearance hole 51, or a bolt plug screwed and connected to the clearance hole 51, the purpose of which is to block the clearance hole 51.

[0049] In this embodiment, a gate-shaped beam 11 is welded to the top of the base 1, and two vertical beams 111 on the gate-shaped beam 11 are welded with a bearing sleeve 1111 which is mounted on the cylinder frame 3 and located on one side of the groove cover 5. The bearing sleeve 1111 is rotatably connected to the cylinder frame 3, and the crossbeam on the top of the gate-shaped beam 11 acts as a handle, making it more convenient to move the battery module.

[0050] It should be noted that a wire hole is provided on the heat sink 6 to facilitate the external wires of the battery module 2, and a wire tube is provided on the large cover 101 to facilitate the external connection of the wires electrically connected to all the battery modules 2.

[0051] Example 2

[0052] See also Figure 1 , Fig. 9 and Fig.10, and the difference from Example 1 is that the sleeve 7 is rotatably connected to the barrel frame 3. In specific implementation, a damping rubber sleeve can be provided at the rotatable connection between the sleeve 7 and the barrel frame 3, so that the sleeve 7 has a certain rotation resistance. One side of the sleeve 7 is penetrated and rotatably connected with a plurality of positioning shafts 105 close to the outer peripheral wall. One end of the positioning shaft 105 located in the barrel frame 3 is fixedly connected with a gear 1051. An inner gear ring 31 is fixedly sleeved in the barrel frame 3 near one end and meshed with the gear 1051. The other end of the positioning shaft 105 is fixedly connected with a cantilever 1052 parallel to the sleeve 7. The cantilever One end of 1052 is fixedly connected with a heat dissipation fan 106. In this embodiment, the number of heat dissipation fans 106 is also six. When the sleeve 7 rotates, it will drive the positioning shaft 105 to revolve. Under the meshing cooperation of the gear 1051 and the inner gear ring 31, the heat dissipation fan 106 revolves around the positioning shaft 105. This arrangement enables the heat dissipation fan 106 to be respectively opposite to the vent 71 and the adjacent positioning square tube 4 when moving. The heat dissipation fan 106 is located on one side of the positioning square tube 4, and the groove cover 5 is pulled outward at the same time. The heat dissipation fan 106 can accelerate the heat dissipation of the battery module 2 with high power charging and discharging. When waterproof and moisture-proof treatment is required, the groove cover 5 is controlled to slide inward so that the battery module 2 is in a closed space. At this time, all the heat dissipation fans 106 are controlled to be located at the vent 71, thereby increasing the air volume passing through the heat dissipation plate 6, achieving waterproof and moisture-proof functions while ensuring heat dissipation performance.

[0053] Furthermore, it also includes a linkage mechanism 107, which is arranged in the barrel frame 3. When the envelope 7 rotates and drives a plurality of cooling fans 106 to be opposite to the vent 71 at the same time, under the transmission of the linkage mechanism 107, a plurality of slotted covers 5 move to the extreme position in the axial direction of the barrel frame 3. When the envelope 7 rotates and drives a plurality of cooling fans 106 to be located at a position where the diameter of the same circle is greater than the outer diameter of the barrel frame 3, a plurality of slotted covers 5 move to the extreme position in the direction away from the axis of the barrel frame 3. In other words, by controlling the rotation of the envelope 7, when all the slotted covers 5 are opened synchronously, all the cooling fans 106 are respectively located on one side of the adjacent battery module 2, and when all the slotted covers 5 are closed synchronously, all the cooling fans 106 are concentrated at the vent 71, which has the advantage of more convenient switching operation.

[0054] Specifically, both sides of the groove cover 5 are welded with connecting rods 52 that penetrate the outer peripheral wall of the cylinder frame 3, the linkage mechanism 107 includes a door-shaped rod 1071, a gear 1072 and an outer gear ring 731, and the inner peripheral wall of the cylinder frame 3 and the position between the two adjacent positioning square tubes 4 are provided with a door-shaped rod 1071, and the horizontal rod 10711 on the door-shaped rod 1071 is rotatably connected to the cylinder frame 3, and the two vertical rods 10712 on the door-shaped rod 1071 are telescopic rod structures and the free ends of the two connecting rods 52 on the adjacent groove cover 5 are respectively connected to the The free end is hingedly connected, wherein the vertical rod 10712 is a two-section telescopic structure, gear 2 1072 is fixedly arranged at one end of the horizontal rod 10711, and a coaxial support sleeve 73 with a larger aperture than the vent 71 is welded on the inner side of the sleeve 7, and the outer sleeve of the support sleeve 73 is provided with an outer gear ring 731 meshing with gear 2 1072. When the sleeve 7 rotates, it drives the outer gear ring 731 to operate, and when the outer gear ring 731 operates, it drives the corresponding door-type rod 1071 to swing through gear 2 1072, and then drives the groove-type cover 5 to approach and move away from the cylinder frame 3 through the connecting rod 52.

[0055] It should be noted that in order to improve the stability of the sleeve 7 after rotation, an ear plate can be fixed on the outer wall of the sleeve 7, and then a limit bolt can be screwed on the ear plate, at least two circumferentially distributed positioning plates are welded on the outer wall of the cylinder frame 3, and then limit holes are opened on the positioning plates. After the sleeve 7 is rotated, the limit bolt is rotated so that one end of the limit bolt is inserted into the limit hole on one of the positioning plates. At this time, the rotating sleeve 7 can be locked.

[0056] Working principle: During use, when high-power discharge is required, the battery module 2 will have a problem of high heat generation. At this time, the cover 7 is manually rotated, and all the groove covers 5 are synchronously moved outward under the transmission of the linkage mechanism 107. The space between adjacent groove covers 5 and between the groove covers 5 and the barrel frame 3 is increased. The battery module 2 is in direct contact with the outside air through the ventilation window 41. Under the transmission of the positioning shaft 105, the cooling fan 106 is located on one side of the adjacent battery module 2. The cooling fan 106 is electrically connected to the adjacent battery module 2. When the cooling fan 106 is started, the heat dissipation of each battery module 2 will be accelerated.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
