Description

Technical Field

[0001] The utility model relates to the field of power exchange equipment, in particular to a plane pneumatic jacking device for power exchange. Background Art

[0002] In the power battery system, the battery generates excess heat when it is working. The heat is transferred through direct or indirect contact between the battery cell or module and the surface of the aluminum device, and is eventually carried away by the coolant passing through the internal flow channel of the device. This aluminum device is the liquid cooling plate. When the battery is placed, the liquid cooling plate needs to be in contact with the bottom of the battery to enable the liquid cooling plate to dissipate the heat on the surface of the battery.

[0003] At present, after the battery is replaced, when the battery is charged and discharged, in order to avoid the battery surface temperature being too high or too low, the battery is generally placed directly on the liquid cooling plate. The direct placement of the battery will cause the battery to scratch the surface of the liquid cooling plate, which will damage the liquid cooling plate over a long period of time and affect the normal use of the liquid cooling plate. Based on this, a flat pneumatic jacking device for battery replacement is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figures 1 to 4 As shown, the flat pneumatic lifting device for battery replacement in this embodiment includes a base frame 1, mounting plates 2 are installed on both sides of the base frame 1, and rotating wheels 3 are installed on the opposite end surfaces of the mounting plates 2 through rotating shafts. The mounting plates 2 are used to install the rotating wheels 3. The arrangement of the rotating wheels 3 makes it convenient to put the battery into the base frame 1 and take the battery out of the base frame 1. A support frame 4 is installed at the bottom end of the base frame 1. The support frame 4 installs a lifting airbag 5, and a lifting airbag 5 is installed on the upper end of the support frame 4. Bag 5, a liquid cooling plate 6 is installed above the lifting airbag 5, and the lifting airbag 5 is inflated and deflated by external pneumatic equipment. The lifting airbag 5 drives the liquid cooling plate 6 to contact the bottom end of the battery. The liquid cooling plate 6 contacts the bottom end of the battery and avoids scratches on the liquid cooling plate 6 when the battery is placed. A heat exchange flow channel is provided on the lower end surface of the liquid cooling plate 6, and the liquid cooling plate 6 is connected to an external heat exchanger. The liquid cooling flow channel is used for the heat exchange medium to circulate at the bottom of the liquid cooling plate 6, so as to realize the heat dissipation of the liquid cooling plate 6 to the bottom end of the battery.

[0022] Specifically, an air cavity 7 is arranged inside the lifting airbag 5, and a plurality of protrusions 8 are arranged on the upper end of the lifting airbag 5. The protrusions 8 are conical in shape, and the interior of the protrusions 8 are connected to the air cavity 7. Adjacent protrusions 8 are connected by air passages 9. A supporting air passage 15 is arranged on the upper end of the lifting airbag 5 outside the plurality of protrusions 8. The supporting air passage 15 is connected to the air passage 9. The lifting airbag 5 is in contact with the liquid cooling plate 6 through the protrusions 8. When the lifting airbag 5 is inflated, the gas fills the air cavity 7, and the protrusions 8 and the supporting air passage 15 support the lifting airbag 5.

[0023] Furthermore, the top ends of the multiple protrusions 8 are in contact with the bottom ends of the liquid cooling plates 6 between the heat exchange channels. When the protrusions 8 are in contact with the liquid cooling plates 6, the protrusions 8 will not be in contact with the heat exchange channels at the bottom ends of the liquid cooling plates 6, thereby preventing the surface heat of the heat exchange medium inside the heat exchange channels from affecting the service life of the lifting airbag 5.

[0024] Furthermore, guide rods 10 are installed on both sides of the bottom end of the liquid cooling plate 6 between the heat exchange flow channels, through holes 11 are arranged on both sides of the upper end of the lifting airbag 5, and guide tubes 12 are installed on both sides of the support frame 4. The guide rods 10 penetrate the through holes 11, and the lower ends of the guide rods 10 extend into the guide tubes 12. The guide rods 10 guide the movement of the liquid cooling plate 6. When the liquid cooling plate 6 drives the guide rods 10 to move, the guide rods 10 move inside the guide tubes 12, and the diameter of the guide rods 10 matches the inner diameter of the guide tubes 12.

[0025] Furthermore, the surface of the supporting airway 15 is connected with an air pipe 13 , and the air pipe 13 is connected to an external pneumatic device. The external pneumatic device inflates and deflates the lifting airbag 5 through the supporting airway 15 , thereby achieving inflation and deflation of the lifting airbag 5 .

[0026] Furthermore, a wear-resistant layer 14 is installed at the bottom of the lifting airbag 5. The wear-resistant layer 14 has a certain wear resistance to prevent the bottom of the lifting airbag 5 from being worn out due to long-term use.

[0027] The method of using this embodiment is as follows: when in use, first, the lifting airbag 5 is deflated through an external pneumatic device, and the lifting airbag 5 drives the liquid cooling plate 6 to descend so that the height of the liquid cooling plate 6 is located inside the base frame 1, and the battery-swap battery is pushed into the base frame 1 by rotating the wheel 3, and then the pneumatic device is controlled to inflate the lifting airbag 5, and the gas fills the inside of the air cavity 7. The lifting airbag 5 drives the liquid cooling plate 6 to rise, so that the liquid cooling plate 6 and the bottom end of the battery-swap battery are in contact, and at the same time, the external heat exchanger drives the flowing medium to flow inside the liquid cooling channel, so that the liquid cooling plate 6 absorbs the heat at the bottom end of the heat exchange battery. When the battery-swap battery needs to be taken out, the lifting airbag 5 is controlled to deflate, and the battery-swap battery can be slid out from the inside of the base frame 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
