[ detailed description ] embodiments

Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1 to 3, an embodiment of the charging base of the present invention includes a base 1, an electrical connector 2, and a battery connection module 3. The charging base can transmit the power of a battery 4 inserted into the battery connecting module 3 to an electronic device 5 which is positioned on the base 1 and electrically connected with the electric connector 2. The electronic device 5 is not limited by the socket position and the length of the electric wire in the use environment, and is more flexible and convenient to use.

The detailed construction and connection of the various elements are described in detail below:

the base 1 has a receiving cavity 11 for receiving the electronic device 5, and the size of the receiving cavity 11 can be adjusted according to the size of the electronic device 5. The electric connector 2 is disposed on the base 1 and at the bottom of the accommodating groove 11, and when the electronic device 5 is mounted in the accommodating groove 11, the electric connector 2 is electrically connected to the electronic device 5.

The battery connection module 3 can be used to electrically connect a battery 4, and the battery connection module 3 is connected to the base 1 and electrically connected to the electrical connector 2, so as to transmit the power of the battery 4 to the electronic device 5. The battery connection module 3 includes a housing 31, a cassette 32, at least one latch mechanism 33, at least one elastic mechanism 34, a pair of guide rails 35, and a circuit unit 36.

Referring to fig. 4 to 6, the housing 31 is used to connect with the base 1 and has an accommodating space 311, an installation opening 312 for communicating the accommodating space 311 with the outside, and a supporting wall 313 opposite to the installation opening 312. The mounting opening 312 allows the battery 4 to pass therethrough. The supporting wall 313 has at least one guiding hole 314, in the present embodiment, the number of the at least one guiding hole 314 is two, and the function of the guiding holes 314 will be described in detail later.

Referring to fig. 5 and 6, the cassette 32 is disposed in the accommodating space 311 and located between the mounting opening 312 and the abutting wall 313. The cassette 32 is movable at least to a loading position (fig. 5) adjacent to the mounting opening 312 and a power supply position (fig. 6) adjacent to the abutting wall 313 in a first direction D1. The length of the cassette 32 in the first direction D1 is slightly smaller than that of the battery 4, so that when the battery 4 is accommodated in the cassette 32 and the cassette 32 is in the dismounting position, the battery 4 protrudes out of the mounting opening 312, and a user can conveniently extract the battery 4. The cassette 32 defines a battery installation space 321 for accommodating the battery 4, and the cassette 32 includes an opening 322 aligned with the installation opening 312 for accommodating the battery 4 into the battery installation space 321, a connecting wall 323 opposite to the opening 322 and adjacent to the abutting wall 313, two side walls 324 opposite to each other and respectively connected to two sides of the connecting wall 323 and extending along the first direction D1, and two clipping walls 325 respectively connected to the connecting wall 323 and two upper and lower sides of the side walls 324. The opening 322 is defined by the clamping walls 325 and the sidewalls 324. Referring to fig. 7, it is noted that the cartridge 32 further includes two notches 326 respectively symmetrically formed on the side walls 324 and close to the connecting wall 323, two retaining grooves 327 respectively formed on the interface between the side walls 324 and the corresponding notches 326 and close to the connecting wall 323, and two opposite retaining members 328 respectively disposed on the side walls 324, wherein the two retaining members 328 elastically protrude into the battery mounting space 321 and are used for commonly retaining the battery 4. More specifically, each of the fastening members 328 has a fixing portion 328a screwed to the outer side of the corresponding sidewall 324, an elastic arm 328b extending from the fixing portion 328a into the gap 326 and bending and extending into the battery mounting space 321, and a stopping portion 328c extending from the elastic arm 328b into the corresponding stopping groove 327, and the stopping portion 328c can move in the stopping groove 327. When the battery 4 is inserted into the battery installation space 321, the elastic portions of the fastening members 328 are respectively pushed outward, and the stopping portion 328c moves away from the original position, because the fastening members 328 have elasticity, the restoring force of the fastening members 328 can be used for clamping the battery 4, so that the battery 4 can be fixed in the battery installation space 321 without being easily shifted when not being replaced by a user.

Referring to fig. 5 and 6, each of the latch mechanisms 33 includes a bolt 331 and a push latch 332, and one of the bolt 331 and the push latch 332 is disposed on the connecting wall 323, and the other is disposed on the supporting wall 313, and the push latch 332 and the bolt 331 can be locked by a press-locking and then released from each other. In the present embodiment, the number of the at least one latch mechanism 33 is two, but not limited thereto, each bolt 331 is disposed on the connecting wall 323 of the cassette 32, and each push latch 332 is disposed on the abutting wall 313 of the housing 31. When the cartridge 32 is pushed to the power supply position, the bolts 331 are locked by the corresponding push latches 332, so that the cartridge 32 can be fixed at the power supply position without being stressed again. Since the battery 4 in the cartridge 32 is not easily drawn out by the user when the cartridge 32 is in the power supply position, the battery 4 can be withdrawn together with the cartridge 32 by the user applying a pushing force to the battery 4 by the design of the latch mechanisms 33.

Each elastic mechanism 34 includes a guiding pillar 341 disposed on the connecting wall 323 along the first direction D1, and an elastic member 342 disposed on the guiding pillar 341. The guiding column 341 has a hollow circular tube shape. One end of the elastic member 342 abuts against the connecting wall 323, and the other end abuts against the abutting wall 313. In the present embodiment, the number of the at least one elastic mechanism 34 is two, and the two latch mechanisms 33 are located between the two elastic mechanisms 34, but not limited thereto. The two elastic mechanisms 34 respectively correspond to the two guiding holes 314 of the abutting wall 313, and the inner diameter of each guiding hole 314 is larger than the corresponding guiding column 341 and smaller than the corresponding elastic member 342, so that only the guiding column 341 can penetrate through. The elastic mechanisms 34 are designed to make the cartridge 32 smoothly return from the power supply position to the disassembly position, when the cartridge 32 is located at the power supply position, the latch mechanisms 33 are locked, the guiding posts 341 respectively penetrate into the corresponding guiding holes 314, so that the elastic members 342 are compressed by the abutting walls 313 and the connecting walls 323 and store elastic potential energy, and when the latch mechanisms 33 are unlocked and separated, the elastic potential energy stored by the elastic members 342 is released and pushes the cartridge 32 back to the disassembly position.

The pair of guide rails 35 are disposed in the accommodating space 311, are respectively located at two sides of the cassette 32 and extend along the first direction D1, and the pair of guide rails 35 are used for guiding the cassette 32 to move in the first direction D1.

The circuit unit 36 is used for electrically connecting the battery 4 and the electrical connector 2. The circuit unit 36 includes a terminal base 361 provided in the cartridge 32 and adapted to be in contact with the terminals of the battery 4 to form an electrical connection, a detection switch 362 provided in the connection wall 323 of the cartridge 32, and a control circuit (not shown) electrically connected to the terminal base 361 and the detection switch 362. In addition, the housing 31 further includes a protrusion 315 corresponding to the detection switch 362 and protruding toward the detection switch 362. When the cassette 32 is located at the dismounting position, the detecting switch 362 is spaced from the protrusion 315, and the terminal seat 361 is not conducted with the electrical connector 2 through the control circuit; when the cassette 32 is located at the power supply position, the detection switch 362 contacts with the protrusion 315, and the terminal base 361 is conducted with the electrical connector 2 through the control circuit.

The process of the user using the charging base to transmit the power of the battery 4 to the electronic device 5 and replace the battery 4 is as follows: first, the electronic device 5 is installed in the accommodating groove 11, so that the electrical connector 2 is electrically connected to the electronic device 5. Then the battery 4 is inserted into the cartridge 32 through the mounting opening 312, a pushing force is applied to move the battery 4 and the cartridge 32 from the dismounting position to the power supply position, the bolt 331 of the latch mechanism 33 is pressed into the push latch 332 to be latched and locked, meanwhile, the elastic member 342 of the elastic mechanism 34 is compressed, the detection switch 362 contacts with the protrusion 315, and the terminal seat 361 is conducted with the electrical connector 2 through the control circuit, and the charging seat can transmit the power of the battery 4 to the electronic device 5. When the battery 4 is not charged and needs to be replaced with a new battery 4, the user only needs to apply a pushing force to the battery 4 together with the cassette 32, the bolt 331 of the latch mechanism 33 will be unlocked and separated from the pushing latch 332, and the cassette 32 of the battery 4 will be restored to the dismounting position by the action of the elastic member 342 of the elastic mechanism 34, and the detection switch 362 is spaced from the protrusion 315 and the terminal base 361 is not conducted with the electrical connector 2 through the control circuit, at this time, the battery 4 can be easily extracted, and the above steps are repeated to replace with a new battery 4.

In summary, the charging base and the battery connection module 3 of the present invention can rapidly replace the battery 4 by the cooperation of the cassette 32, the latch mechanism 33, and the elastic mechanism 34, so as to achieve the object of the present invention.
