[0060] Specifically, in order to place the battery 211, the battery unit further includes a detachable battery bottom shell 213 disposed at the bottom of the battery housing 212, such as Figure 2 As shown, the battery housing 212 and the battery bottom shell 213 can be jointly arranged to form a cavity for accommodating the battery 211 so that the battery 211 can be placed in the cavity.

[0061] In addition, the battery unit further includes a detachable battery cover 214 disposed on the top of the battery housing 212 .

[0062] In order to allow the battery 211 to power the tumor electric field therapy device, the battery bottom shell 213 is also provided with a connecting portion 215 electrically connected to the battery 211. The connecting portion 215 can realize stable power supply from the battery compartment to the electrical components in the tumor electric field therapy device.

[0063] In a possible implementation, the connection portion 215 includes a battery contact plate 2151 and a connector 2152:

[0064] The battery contact plate 2151 is disposed below the battery 211 and is electrically connected to the battery bottom shell 213 via the connector 2152 .

[0065] Specifically, Figure 2 As shown, the connector 2152 can be a blade-type connector, and the battery contact plate 2152 and the connector 2152 can cooperate to electrically connect the battery 211 with the battery bottom shell 213, so that when the battery part and the battery sleeve 22 are matched, it is beneficial to facilitate the electrical connection between the battery part and the battery sleeve 22.

[0066] In one possible implementation, the battery portion also includes a mating portion 216 nested and cooperating with the connecting portion 215 . The mating portion 216 is detachably fixed to the bottom of the battery bottom shell 213 .

In the present application, the battery compartment can include a battery sleeve 22 and a battery portion, the battery sleeve 22 is a cavity structure, and the battery portion can be popped out and locked inside the battery sleeve 22.

[0068] In a possible implementation, the battery sleeve 22 includes a sleeve support member 221 and a sleeve telescopic member 222:

[0069] The sleeve support 221 is disposed at the bottom end of the battery sleeve 22;

[0070] The mating portion 216 is detachably fixed to the battery bottom shell 213 and extends in a direction away from the sleeve support 221;

[0071] The sleeve telescopic member 222 is a hollow structure, one end of which is movably arranged on the sleeve support member 221, and the other end of which is arranged oppositely passes through the telescopic member receiving groove at the bottom end of the battery sleeve 22 and is movably arranged with the matching part 216.

[0072] Specifically, Figure 2 As shown, the sleeve support 221 can be disposed at the bottom end of the battery sleeve 22 to provide corresponding support to the battery sleeve 22 .

[0073] The mating portion 216 is detachably fixed to the battery bottom shell 213 and extends in a direction away from the sleeve support member 221. Figure 2 As shown, the matching portion 216 can be a protruding structure extending in a direction away from the sleeve support 221, and is used to provide corresponding limiting when the first elastic body 217 is reset from a compressed state.

[0074] The sleeve telescopic member 222 is a cavity structure, one end of which is movably arranged on the sleeve support member 221, and a corresponding telescopic member receiving groove may be correspondingly arranged on the sleeve support member 221. One end of the sleeve telescopic member 222 may be arranged on the corresponding telescopic member receiving groove of the sleeve support member 221, and the other end of the sleeve telescopic member 222 passes through the telescopic member receiving groove at the bottom end of the battery sleeve 22, and can be movably arranged with the matching portion 216. In other words, the sleeve telescopic member 222 can be arranged between the sleeve support member 221 and the matching portion 216.

[0076] Specifically, in order to realize the ejection of the battery part, the battery compartment may further include a first elastic body 217 disposed in the cavity of the battery sleeve telescopic member 222, such as Figure 2 As shown, the first elastic body 217 may be a spring.

[0077] like Figure 3 As shown, Figure 3 (a) shows a first partial cross-sectional view of the first elastic body in a compressed state. Figure 3(b) in the figure represents a first partial cross-sectional view when the first elastomer is in a reset state. The length of the first elastomer 217 in a compressed state can match the axial length of the telescopic sleeve member 222, so that the first elastomer 217 can be completely placed in the cavity in the telescopic sleeve member 222 when it is in a compressed state.

[0078] At the same time, since the sleeve telescopic member 222 is arranged between the sleeve supporting member 221 and the matching portion 216 , the bottom end of the first elastic body 217 can contact the sleeve supporting member 221 , and the top end can match the matching portion 216 .

[0079] It should be noted that, when the battery compartment includes a battery portion and a battery sleeve 22 , the locking pin portion 23 can also be used to fix the battery portion in the battery sleeve 22 by compressing the first elastic body 217 .

By pressing the inclined surface on the inclined block included in the battery unlocking button 241, the downward pressure component can be transferred to the inclined surface of each locking pin 231. Each inclined block can slide in the inclined surface groove of the corresponding locking pin 231 until the first end of each locking pin 231 is retracted inward along the radial direction of the battery sleeve 22 and disengaged from the corresponding locking pin groove, thereby avoiding the fixing effect of the locking pin 231 on the battery part. At this time, the first elastic body 217 can be reset and the battery part can be ejected axially from the battery sleeve 22 by the elastic force of the first elastic body 217.

[0093] It should be noted that the second elastic body 232 and the third elastic body 217 provided in this embodiment are independent of each other. When the battery unit needs to be fixed in the battery sleeve 22, the inclined surface of the lock pin 231 can cause the lock pin 231 to slide inward along the lock pin groove, and the second elastic body 232 will be compressed, so that the battery unit is fixed by clamping the lock pin 231 in the lock pin groove. In this process, the movement of the lock pin 231 does not affect the state of the third elastic body 217, that is, the third elastic body 217 remains unchanged. That is, in this embodiment, the battery unlocking key 241 can drive the lock pin 231, but the lock pin 231 cannot drive the battery unlocking key 241.

[0094] In a possible implementation, the elastic force of the first elastic body 217 is greater than the elastic force of the third elastic body 242 .

[0095] When unlocked by the battery unlocking button 241 and the third elastic body 242, the battery unlocking button 241 will cause the locking pin 231 to slide inward until it is out of the locking pin groove of the battery sleeve 22. At this time, the first elastic body 217 with greater elastic force can instantly push the battery part outward.

[0096] It should be noted that since the operator's reaction time is usually slow, when the first elastic body 217 pushes the battery part outward, the operator's hand may still remain on the battery unlocking key 241. At this time, the battery part pushed outward will force the third elastic body 242 to be further compressed, and the locking pin 231 will continue to slide inward, which is conducive to smoothly unlocking the battery part.

[0097] In practical applications, the corresponding key unlocking vertical stroke can be determined by setting the elastic force of the first elastic body 217 and the elastic force of the third elastic body 242. The key unlocking vertical stroke can be greater than 2.5 mm. For example, the key unlocking vertical stroke can be 3.5 mm, thereby avoiding accidental ejection of the battery part due to misoperation due to too small an unlocking stroke.

[0098] In one possible implementation, Figure 2 As shown, the battery compartment includes a sensing circuit board 25 and a printed circuit light board 26:

[0099] A battery panel 27 is provided between the battery cover 214 and the top of the battery housing 212 , and the battery panel 27 has a third opening corresponding to the battery unlocking key 241 ;

[0100] The induction circuit board 25 is disposed in the interlayer between the battery cover 214 and the battery panel 27. There is a gap between the induction circuit board 25 and the battery cover 214. The induction circuit board 25 is electrically connected to the printed circuit light board 26.

[0101] The printed circuit light board 26 is disposed between the battery panel 27 and the battery portion. The printed circuit light board 26 is electrically connected to the battery cell 211 . The battery top shell 212 is provided with a fourth opening for guiding light emitted by the printed circuit light board 26 .

[0102] Specifically, the battery part is connected to the printed circuit board 26, and the sensing circuit board 25 is connected to the printed circuit board 26. The sensing circuit board 25 is arranged in the interlayer between the battery surface cover 214 and the battery panel 27. A gap can be set between the sensing circuit board 25 and the battery surface cover 214. For example, the distance between the sensing circuit board 25 and the battery surface cover can be about 1.5 mm. When the hand of the relevant personnel touches the battery surface cover 214, the power level of the battery part can be displayed through the sensing circuit board 25 and the printed circuit board 26.

[0103] Displaying the power level by induction can avoid the risk of damaging the power display button due to long-term pressing of the button in the related art.

[0104] In a possible implementation, the battery compartment includes a light guide column 28 , which is disposed on the inner side of the battery cover 214 , and the light guide column 28 is electrically connected to the printed circuit light board 26 .

[0105] Specifically, in order to better display the power level, the battery compartment may include a light guide column 28, and the light guide column 28 may include a plurality of columns, so that the power level of the battery unit can be displayed by lighting up different columns, such as Figure 2 As shown, the light guide column 28 may include four columns, and the light guide column 28 having four columns may display four levels of battery power.

[0106] In a possible implementation, in order to ensure the electrical connection between the battery portion and the battery sleeve 22, the battery compartment may include an electric contact male connector and an electric contact female connector:

[0107] The male contact is arranged on the fifth opening at the bottom end of the battery sleeve 22 along the axial direction of the battery sleeve 22, and the female contact is arranged on the sixth opening of the battery bottom shell 212 corresponding to the fifth opening along the axial direction of the battery sleeve 22;

[0108] When the battery is inserted into the battery sleeve 22 , the female contact socket contacts the male contact socket.

[0109] In a possible implementation, the bottom end of the battery sleeve 22 includes a third boss, the battery bottom shell 212 includes a groove matched with the third boss, and the axial length of the third boss is greater than the axial length of the contact male head;

[0110] When the battery portion is inserted into the battery sleeve 22 , the third protrusion is engaged with the corresponding groove.

[0111] Specifically, when the battery compartment includes a male contact and a female contact, in order to achieve positioning between the male contact and the female contact, as Figure 2 As shown, the bottom end of the battery sleeve 22 may include a third boss, and the battery bottom shell 212 may include a groove matching the third boss. When the battery part is removed into the battery sleeve 22, before the male contact and the female contact seat contact, the third boss may first engage with the groove to align the position of the female contact seat and the male contact head, thereby protecting the female contact seat and the male contact head with low strength, and at the same time also improving the contact stability between the female contact seat and the male contact head.

[0112] In one possible implementation, Figure 2 As shown, the number of the third bosses is two, and the number of the grooves is two.

[0113] In a possible implementation, the inner side of the side wall of the battery sleeve 22 includes an elastic boss, and both sides of the elastic boss include elastic arms;

[0114] When the battery portion is inserted into the battery sleeve 22 , the elastic boss contacts the battery portion.

[0115] The elastic boss can reduce the shaking of the battery when the tumor electric field therapy device is in a dynamic environment, thereby ensuring the contact stability of the battery. In practical applications, the number of elastic bosses can be multiple.

[0116] In a possible implementation, a soft glue 29 may be disposed between the battery unlocking button 241 and the top of the battery housing 212 , and the soft glue 29 is compressed by the elastic force provided by the third elastic body 242 , thereby providing a waterproof effect greater than IPX2.

[0117] In summary, the present application provides a battery unit and a battery compartment adapted for a tumor electric field therapy device, wherein the battery unit includes a battery and a battery shell, wherein the battery is embedded in the battery shell, and further includes at least one locking pin unit that is retractably arranged with the battery shell, and a battery unlocking button unit that is driven by the locking pin unit. After the locking pin unit penetrates the battery shell, it is retractably arranged in a direction away from the battery; after the battery unlocking button unit penetrates the battery shell, it is switchable between locking and releasing with the locking pin unit. Through the above structure, the battery can be locked in the battery shell by the locking pin unit to ensure the safe use of the battery. At the same time, the battery unlocking button unit can be used to simply switch between locking and releasing the battery, which is conducive to timely replacement of the battery.

[0118] In addition, while the battery compartment is able to power the tumor electric field therapy device, it can also stably match the battery part with the battery sleeve, ensuring the safe use of the tumor electric field therapy device.
