Further, the second contact surface 21 is located at the front end of the battery case 2, the first contact surface 11 is located at the rear side of the upper end of the charging stand 1, and the second vent 23 is located at the end of the battery case 2 away from the second vent 22.
In addition, when charging, as shown in fig. 1 and 2, the battery case 2 may be inserted into the charging stand 1, and at this time, the contact surface one 11 and the contact surface two 21 are attached to each other, so that the vent one 12 and the vent two 22 are communicated with each other, that is, the vent one 14, the inner cavity one 13, the vent one 12, the vent two 22, the interior of the battery case 2, and the vent two 23 form an air flow path, that is, the battery heat dissipation air duct 7 as shown in fig. 5.
In this embodiment, the specific implementation scenario is: first, the fan 4 sends air for cooling into the first cavity 13 through the first vent 14, after the air enters the battery case 2 through the first vent 12 and the second vent 22, the heat of the battery body 3 can be dissipated, and finally, the air is discharged through the second vent 23. After the air enters the inner cavity I13, the air flows in the inner cavity I13, so that the flow equalization effect can be achieved. In the above technical scheme, through installing the fan one 4 additional in the inside of charging seat 1, can play the radiating effect to the battery body 3 in the battery casing 2 through battery heat dissipation wind channel 7, need not install the radiator additional in the inside of battery casing 2.
Referring to fig. 1, 2, 3, 4 and 5 of the specification, side air openings 15 are formed on two sides of the charging seat 1, two fans 41 are fixedly mounted on two sides of the inside of the charging seat 1, one fan 41 is used for supplying air to the inside of the charging seat 1, and the other fan 41 is used for blowing air inside the charging seat 1 to the outside of the charging seat 1.
By providing the two fans two 41, air can be introduced into the charging stand 1 from the side air inlet 15 on one side, and then be blown out of the charging stand 1 from the side air inlet 15 on the other side, that is, the heat dissipation path is shown as the charging stand heat dissipation air duct 8 in fig. 5, so that the electronic components in the charging stand 1 can be dissipated.
Further, as shown in fig. 4, the male plug 17 is mounted at the end of the mounting groove 16, the female plug 26 is mounted at the bottom of the battery case 2, and the male plug 17 is inserted into the female plug 26 when charging.
Further, as shown in fig. 2 and 3, the upper end of the charging stand 1 is provided with a mounting groove 16, the bottom of the battery case 2 is provided with a slide 25, and the battery case 2 is inserted into the charging stand 1 by inserting the slide 25 into the mounting groove 16.
It should be noted that a fastening member may be provided at the bottom of the battery case 2, and after the slide 25 is mounted in the mounting groove 16, the charging stand 1 and the battery case 2 may be fixed by the fastening member to prevent loosening.
Referring to fig. 8 of the specification, the battery body 3 includes a plurality of laterally arranged battery cells 31, two ends of each battery cell 31 are provided with a bracket 32, the ends of each battery cell 31 are mounted on the brackets 32, each battery cell 31 is cylindrical, air channels 33 are formed on the upper side and the lower side between adjacent battery cells 31, and the direction of the ends of each battery cell 31 faces the direction of the vent holes 22.
After the air enters the battery body 3 through the second vent hole 22, the air may radiate heat from the air duct 33 through the battery cell 31.
For portability and aesthetic reasons of the charging stand 1, the height of the charging stand 1 cannot be set high, that is, when the battery case 2 is inserted on the charging stand 1, it is located at the lower side of the battery case 2. Therefore, when air is blown out from the vent two 22, the air on the lower side inside the battery case 2 flows faster, while the air on the upper side flows relatively slower. Furthermore, after the hot air is generated inside the battery case 2, the hot air rises and accumulates on the top of the battery case 2, but the air flow passes relatively slowly just at the position of the top of the battery case 2. Therefore, although the battery cells 31 can be cooled, the cooling degree is different, and after long-term use, the performance of the battery cells 31 will be unbalanced, and when one of the battery cells 31 slides down, the battery cells 31 will slide down with a continuous charging for a long time, and the overcharging of the other battery cells 31 will be caused.
Based on the above, referring to fig. 4, 7 and 8 of the specification, one end of the battery case 2, which is close to the vent hole two 22, is provided with the inner cavity two 24, the inner cavity two 24 is provided with the air guiding frame 5, the air guiding frame 5 is fixedly connected with the battery case 2, the air guiding frames 5 are provided with air guiding holes 51 corresponding to the air channels 33 one by one, and the end parts of the air guiding holes 51 are close to the end parts of the air channels 33.
It should be noted that, after the air enters the second cavity 24 from the second vent 22, the air will have a certain flow equalizing effect in the second cavity 24, and then the air is directly blown into the air duct 33 from the air guiding hole 51, so that the outside of each battery cell 31 can have a faster air flow to take away heat, thereby ensuring a balanced heat dissipation effect and avoiding the imbalance of the performance of the battery cells 31 caused by different heat dissipation degrees.
Further, a guide plate 6 is arranged in the second inner cavity 24, the guide plate 6 is positioned on one side of the air guide frame 5, which is close to the second vent hole 22, and a plurality of third vent holes 61 are formed in the guide plate 6.
It should be noted that, the air entering the second cavity 24 from the second vent hole 22 passes through the third vent hole 61 and then passes through the air guide holes 51, so that the air guide plate 6 can have an effect of equalizing flow once, and prevent the air entering from the second vent hole 22 from being blown to the position of the lowermost air guide hole 51 too much.
Further, the third vent 61 and the second vent 22 are staggered, a control shaft 62 is fixedly connected to one side of the baffle 6 close to the second vent 22, the control shaft 62 is movably inserted on the side wall of the battery shell 2 and extends to the outside of the battery shell 2, an elastic supporting piece 63 is mounted on one side of the baffle 6 close to the air guide frame 5, and the elastic supporting piece 63 is used for pushing the baffle 6 to the second vent 22 so that the baffle 6 plugs the second vent 22.
Specifically, the elastic support 63 includes a fixing rod 631, one end of the fixing rod 631 is fixedly connected with the air guiding frame 5, the other end of the fixing rod 631 is movably inserted on the air guiding plate 6, a spring 632 is sleeved on the outer side of the fixing rod 631, and two ends of the spring 632 are respectively pressed with the air guiding frame 5 and the side wall of the air guiding plate 6.
When the battery case 2 is not inserted into the charging stand 1 for charging, the side wall of the baffle 6 is attached to the inner side wall of the battery case 2, and the second vent hole 22 and the third vent hole 61 are staggered, so that the baffle 6 can block the second vent hole 22, and the spring 632 pushes the baffle 6 to extend the control shaft 62 out of the battery case 2. When the battery case 2 is inserted into the charging seat 1 for charging, the first contact surface 11 pushes the control shaft 62, so that the baffle 6 is separated from the inner sidewall of the battery case 2, and at this time, air can enter the second cavity 24 from the second vent hole 22 to dissipate heat of the battery body 3. The purpose of blocking the vent two 22 by the baffle 6 when not charging is to reduce the amount of dust entering the interior of the battery housing 2.
In the above scheme, the flow guide plate 6 can play a role in flow equalization and also play a role in blocking the vent hole II 22 and reducing dust.
Finally: the foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
