Referring to fig. 1 to 5, the present embodiment provides a battery split structure of an electronic device, which mainly enables a user to bi-directionally split two batteries 500 on the same electronic device with two hands. The electronic device may be an upper part (as shown) with a screen or a lower part (not shown) with a keyboard in a notebook computer, and may be a tablet computer (not shown). The battery split structure of the electronic device in this embodiment includes: an electronic device body 100 and at least one battery 500 for removably accommodating or assembling the electronic device body 100.

In this embodiment, one side (for example, the outer side of the upper part) of the machine body 100 has a plurality of battery slots 1 and a plurality of toggle structures 2, and the number of the battery slots 1 and the toggle structures 2 can be two or even, and in this embodiment, two are taken as an example for illustration. Each stirring structure 2 is slidably arranged on the machine body 100 corresponding to the position of each battery groove 1, so that each stirring structure 2 can move relative to the machine body 100; and an elastic member 24 (see fig. 3) is respectively connected between each toggle structure 2 and each battery slot 1, so that each toggle structure 2 can respectively reversely move to the original position by the elastic restoring force of each elastic member 24.

Specifically, referring to fig. 1, the machine body 100 has a plurality of thickness sides, wherein the plurality of thickness sides includes an upper side (not shown) and a lower side 101 opposite to each other and two side sides (not labeled) opposite to each other, and the lower side 101 may be a pivoting side of the upper part for direct or indirect pivoting with the lower part. Preferably, the respective toggle structures 2 are disposed on the machine body 100 side by side with respect to the lower edge 101, such that the respective toggle structures 2 are substantially parallel to the lower edge 101 in the length direction and are disposed at two positions of the machine body 100. In addition, each of the shifting structures 2 has a first shifting direction D1 and a second shifting direction D2 opposite to each other, wherein the first shifting direction D1 is a direction indicated by an arrow D1 shown in fig. 1, the second shifting direction D2 is a direction indicated by an arrow D2 shown in fig. 1 (for example, not shown in the drawings, or facing away from each other as shown in fig. 1), and each of the shifting structures 2 can move relative to the machine body 100 along the first shifting direction D1 and the second shifting direction D2 through shifting of the user. The first poking direction D1 and the second poking direction D2 are substantially parallel to the lower edge 101.

Optionally, at least one blocking body is fixedly arranged on one side 20 of each toggle structure 2, and a toggle key 23 is formed on the other side (not labeled with a reference sign) opposite to the one side 20, wherein the toggle key 23 is exposed from the lower edge 101 so as to be beneficial to toggling by a user. The number of the stoppers may be one or two or more, and the present invention is not limited thereto as long as the battery 500 is stopped. In the present embodiment, three baffles, such as three first baffles 21, are taken as an example for illustration; specifically, referring to fig. 3, the three baffles include two first baffles 21 and one second baffle 22, and the second baffle 22 is located between the two first baffles 21.

Alternatively, the number of the batteries 500 may be one, or two or more, in this embodiment, two batteries 500 are taken as an example for illustration, and the two batteries 500 are identical, and any one of the batteries 500 can be assembled in any one of the battery slots 1, so in the following description of the structure of the batteries 500, only one of the batteries 500 will be described.

Specifically, the battery 500 has a plurality of sides including an adjacent side 501 for being adjacent to the side 20. At least one bidirectional stopper is fixedly arranged on the adjacent side 501 of the battery 500, and the bidirectional stopper is provided with two stopping parts for accommodating the stopper to be stopped. The number of the two-way stoppers may be one or more, and the present invention is not limited thereto, as long as the two-way stoppers can be stopped by any one of the toggle structures 2, and in this embodiment, three two-way stoppers corresponding to the three stoppers are taken as an example, for example, three first two-way stoppers 5; specifically, referring to fig. 4, the three bidirectional stoppers include two first bidirectional stoppers 5 and one second bidirectional stopper 6, and the second bidirectional stopper 6 is disposed between the two first bidirectional stoppers 5.

Specifically, each of the first bidirectional stoppers 5 includes a stopper body 51 and a partition plate 52 standing on the stopper body 51, such that a first stopper 521 and a second stopper 522 are respectively formed between opposite sides of the partition plate 52 and the stopper body 51. Specifically, the stop body 51 has a top edge 511 and two guiding slopes 512, the partition plate 52 is vertically disposed between two ends of the top edge 511, and the two guiding slopes 512 are gradually approaching from two ends of the top edge 511 toward a direction away from the partition plate 52, so as to facilitate guiding the stop body.

Specifically, the second bidirectional stopper 6 includes two baffle plates 61 disposed symmetrically to each other and two guide inclined plates 62 disposed symmetrically to each other. The two baffles 61 are spaced apart from each other and have open corners communicating with each other, respectively, to form a first stop 611 and a second stop 612, respectively, and the two baffles 61 further have two adjacent inner ends 613 spaced apart from each other. The two guiding inclined plates 62 are respectively connected to the two adjacent inner ends 613 and are respectively separated gradually in a direction away from the two baffles 61, so as to be beneficial to guiding the baffles.

Referring to fig. 1, 5 and 6, when any one of the batteries 500 is assembled in the first battery slot 1, the respective blocking bodies (referring to the first blocking body 21 and the second blocking body 22 in the drawing) of the first group of toggle structures 2 will be blocked and blocked by the respective first blocking portions (referring to the first blocking portion 521 of the first bidirectional blocking member 5 and the first blocking portion 611 of the second bidirectional blocking member 6 in the drawing) of the battery 500; when the battery 500 is assembled in the second battery case 1, the blocking bodies (see the first blocking body 21 and the second blocking body 22 in the drawing) of the second group of toggle structures 2 are blocked by being blocked in the second blocking parts (see the second blocking part 522 of the first bidirectional blocking member 5 and the second blocking part 612 of the second bidirectional blocking member 6 in the drawing) of the battery 500.

Specifically, when the two batteries 500 are assembled in the two battery slots 1, the two first blocking bodies 21 of the first group of toggle structures 2 are respectively blocked by being blocked in the first blocking parts 521 of the two first bidirectional blocking members 5 of the first battery 500, and the second blocking bodies 22 of the first group of toggle structures 2 are blocked by being blocked in the first blocking parts 611 of the second bidirectional blocking members 6 of the first battery 500, so that the first group of toggle structures 2 lock (lock) the first battery 500; further, the two first stoppers 21 of the second group switching structure 2 are engaged with the second stoppers 522 of the two first bidirectional stoppers 5 of the second battery 500, respectively, and the second stoppers 22 of the second group switching structure 2 are engaged with the second stoppers 612 of the second bidirectional stoppers 6 of the second battery 500, respectively, so that the second group switching structure 2 locks (lock) the second battery 500.

Referring to fig. 3, 4 and 7, when the assembled two batteries 500 are to be unlocked (unlocked) simultaneously, the user can intuitively dial the two sets of dial structures 2 along the first dial direction D1 and the second dial direction D2 only by using both hands to detect the lower edge 101 and touch the two sets of dial structures 2, so as to unlock the two batteries 500.

Specifically, when the user dials the two sets of dial structures 2 simultaneously along the two directions (the first dial direction D1 and the second dial direction D2), the respective blocking bodies (the first blocking body 21 and the second blocking body 22 in the figure) of the first set of dial structures 2 are respectively withdrawn from the respective first blocking portions (the first blocking portion 521 of the first bidirectional blocking member 5 and the first blocking portion 611 of the second bidirectional blocking member 6 in the figure) of the first battery 500 and are not blocked, so as to unlock (unlock) the first battery 500; further, the respective stoppers (see the first stopper 21 and the second stopper 22 in the drawing) of the second group switching structure 2 are respectively withdrawn from the respective second stopper portions (see the second stopper portion 522 of the first bidirectional stopper 5 and the second stopper portion 612 of the second bidirectional stopper 6 in the drawing) of the second battery 500, and are not stopped, so that the second battery 500 is unlocked (unlocked). This allows easy and intuitive unlocking of the two batteries 500 in a bi-directional split manner.

It should be noted that, the two guiding slopes 512 and the two guiding inclined plates 62 of the battery 500 are mainly used for guiding the first blocking body 21 and the second blocking body 22 respectively when the battery 500 is assembled in the battery slot 1 by being pressed down, so as to push the two sets of toggle structures 2 to move; moreover, the first blocking body 21 and the second blocking body 22 can be used to push the two guiding slopes 512 and the two guiding inclined plates 62 respectively when the battery 500 is unlocked, so as to partially eject the battery 500 from the battery slot 1, thereby facilitating the user to take the battery.

Referring to fig. 6 and 7, one end of the second blocking body 22 of the toggle structure 2 may further have a protrusion 221 corresponding to the adjacent inner end 613, so that the protrusion 221 can be blocked by the adjacent inner end 613, so as to have the effect of preventing the second blocking body 22 from being erroneously inserted into the blocking portions (referring to the first blocking portion 611 and the second blocking portion 612 of the second bidirectional blocking member 6 in the drawings).

Referring to fig. 5, in the battery split structure of the electronic device of the present embodiment, since the toggle structure 2 may further be provided with a functional structure, for example, a structure for detecting whether the battery is assembled or disassembled, the positions of the two blocking bodies (see the first blocking body 21 and the second blocking body 22 in the drawing) on the two toggle structures 2 cannot be completely symmetrical to each other in order to avoid the functional structure. However, the battery split structure of the electronic device of the present invention can achieve the aforementioned object and still have the aforementioned effects even if the battery split structure cannot be completely symmetrical to each other.

In other embodiments, the functional structure may not be provided, so that all the blocking bodies of each toggle structure 2 can be symmetrically configured, thereby having the effect of reducing the cost.

In still other embodiments, the number of stops on the toggle structure 2 may be one, and the number of bi-directional stops on the battery 500 may be relatively one (although the number of stops and bi-directional stops are one, it is sufficient to lock and unlock the battery 500). Specifically, only the first blocking member 21 is fixed at any position on one side 20 of each toggle structure 2, and only the first bidirectional blocking member 5 is fixed at a corresponding position on the adjacent side 501 of the battery 500. Furthermore, since the electronic device can operate with only one battery 500, the number of batteries 500 can be only one, and the battery 500 can be assembled in any battery case 1: when the first battery slot 1 is selected for assembly, the first stop 521 of the first bidirectional stop member 5 of the battery 500 is stopped by the first stop 21 of the first group of toggle structures 2; when the second battery compartment 1 is selected for assembly, the second stop 522 of the first two-way stop 5 of the battery 500 will be stopped by the first stop 21 of the second set of toggle structures 2.

In summary, compared with the prior art, the present invention has the following effects: through the special battery split structure design, a user can unlock the two batteries 500 at the same side (lower side 101) or the same side of the same electronic device at the same time, so that the battery split structure accords with ergonomics, and the user can become intuitive and easy in the operation of unlocking the batteries 500; in addition, any one of the batteries 500 can be assembled in any one of the battery cases 1, and the two batteries 500 can be completely identical and only one mold is required to be opened, so that the trouble of a user is not caused.

In addition, the invention has other effects: even if the two poking keys 23 of the poking structures 2 are exposed from the lower edge 101, the upper part is required to be lifted when the notebook computer is used, and the lower edge 101 of the upper part is downwards hidden after the upper part is lifted; the notebook computer is not required to be covered with the upper member, and the lower side 101 of the upper member is hidden towards the rear side of the whole electronic device after the upper member is covered, so that the attractive appearance of the electronic device is maintained.

Note that the above is only a preferred embodiment of the present invention and the technical principle applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, while the invention has been described in connection with the above embodiments, the invention is not limited to the embodiments, but may be embodied in many other equivalent forms without departing from the spirit or scope of the invention, which is set forth in the following claims.
