What demonstrate in Fig. 4 is the explosive view of mower power source type indicating device according to the embodiment in the utility model.This power supply type indicating device is in mower enclosure interior, and when the various shells of mower are not opened, user only can see slide block 40.But, as shown in Figure 3 b after user opens battery cover 23, can also see that other parts comprise framework 60 and barrier plate etc.As shown in Figure 4, this power supply type indicating device comprises above-mentioned slide block 40, framework 60, key socket 62,64 and barrier plate etc.Specifically, the top of slide block 40 is configured in the chute 42 shown in Fig. 3 a and 3b and slides, to give user visual cues.The lower end of slide block 40 has a connecting hole 44, and this connecting hole 44 can receive the pivot 46 on one end of linking arm 48, thus makes to be formed between slide block 40 and linking arm 48 pivotally connected.Linking arm 48 is in a strip, and its one end has above-mentioned pivot 46, and the other end also has another one pivot 50.Pivot 46 and pivot 50 are positioned at the same side of linking arm 48.Linking arm 48 is pivotally connected on barrier plate by pivot 50.As shown in Figure 4, barrier plate comprises plate body 56 and is connected to this plate body 56 side, and adjutage 54 outward extending with the parallel plane direction at plate body 56 place.Adjutage 54 is connected to groove portion 57 away from the other end of plate body 56, and this groove portion 57 offers link slot 52.The pivot 50 of linking arm 48 is slidably received in link slot 52.In addition, the upper surface of the plate body 56 of barrier plate is also convexly equipped with handle portion 58, this handle portion 58 is for supplying this barrier plate of user's push-and-pull.Preferably, the plate 56 of barrier plate, handle portion 58, adjutage 54 and cell body are by one-body molded and manufacture.Notice linking arm 48 in this embodiment not to be fixedly attached on the housing of mower, but floating connection, only there are its two ends to be connected respectively in the groove portion 57 of slide block 40 and barrier plate.On the contrary, the chute 42 that slide block 40 is limited at Fig. 3 a and 3b due to its top is inner, and therefore it only can carry out rectilinear motion along chute 42.
Above-mentioned framework 60 is fixed on mower inside.The both sides, top of framework 60 are provided with two guide rails be parallel to each other 61.And in the lower surface both sides of the plate body 56 of barrier plate, all there is flange 63.Flange 63 to be installed in guide rail 61 and to be slidably connected with the latter, thus barrier plate is slidedly arranged on this framework 60, and barrier plate can slide relative to framework 60.Inner at framework 60, two key sockets 62 and 64 placed side by side have been installed respectively.Key socket 62 corresponds to battery (dc source) in the present embodiment, and key socket 64 corresponds to external power supply (alternating current).Length due to the plate body 56 of barrier plate is just in time enough to cover key socket 62 and 64 (as shown in Figure 4), and therefore barrier plate can only block one of them of these two key sockets simultaneously, and will expose another one.Between the motor (not shown) that key socket 62 is connected to mower and battery (not shown).And between the motor (not shown) that key socket 64 is connected to mower and AC outlet (not shown).Key socket 62 and 64 all allows the insertion with the matching used key of mower, thus the internal circuit connecting mower enters duty to make mower.This will be described in detail below.
Introduce now the operation principle of above-mentioned power transfer device.Mower in the utility model is configured with AC power interface (such as power line socket) and battery interface simultaneously, thus under making mower not only can be operated in alternate current states but also under direct current state can be operated in.But, in order to prevent mower connection one of them power supply in another power supply on its work cause interference or affect its circuit, therefore mower of the present utility model employs key.No matter be that mower will by powered battery or external AC-powered, all to insert key and just can connect circuit and make the electric power of power supply to arrive motor in corresponding socket.The inside of key comprises fuse, is inserted into key socket and just can connects dead circuit originally, make the circuit communication of mower inside.
See Fig. 5, when barrier plate moves to the position of closer slide block 40 on Fig. 5 middle frame 60, barrier plate has blocked the key socket 62 in Fig. 4, but exposes key socket 64.Now, key 66 can be inserted into the key socket 64 in Fig. 4.Now, conducted due to the insertion of key 66 between the AC power that key socket 64 is connected to and motor, therefore now mower enters the preparation state of alternating current.
If user will switch to powered battery, so first he will extract key 66, then moved to the direction away from slide block 40 by the handle portion 58 promoted on barrier plate, this will make that the key socket 64 in Fig. 4 is blocked and key socket 62 is exposed.In the moving process of barrier plate, adjutage 54 and the groove portion 57 of barrier plate are also moved linearly.This is due to the length of adjutage and the glide direction of barrier plate is parallel causes.But owing to being an angle between groove portion 57 and adjutage 54, therefore the rectilinear motion in groove portion 57 causes the pivot 50 (see Fig. 4) of the linking arm 48 being positioned at groove portion 57 to occur and the movement on adjutage 54 moving direction difference other direction.Because linking arm 48 as above is not fixed on the housing of mower itself, the movement in therefore above-mentioned groove portion 57 causes linking arm 48 itself to rotate.And due to slide block 48 be slidably installed in the chute on mower housing, therefore the rotation of linking arm 48 can cause slide block 40 that translation occurs, and makes it in the chute of mower surface of shell, move to the second place from primary importance.So, user just the power supply type that can intuitively arrive indicated by slide block 40 become battery from alternating current.Then, after above-mentioned parts have moved, key is inserted key socket 62, this just becomes the configuration shown in Fig. 6.Now, conducted due to the insertion of key 66 between the battery motor that key socket 62 is connected to, therefore now mower enters battery powered readiness for operation.
If user will switch to regard to AC-powered again under battery-powered state, so only need to extract key again and promoted by the rightabout of the handle portion 58 of barrier plate to the other end, whole power supply type indicating device just can get back to the state described in Fig. 5.And the second place in the chute by mower surface of shell is also moved to primary importance by slide block 40.So, user just the power supply type that can intuitively arrive indicated by slide block 40 become alternating current from battery.Generally speaking, user is by the handle portion 58 of mobile barrier plate and be aided with key 66 is inserted corresponding key socket, just can complete optionally by the first power supply (such as alternating current) or second source (such as direct current) insertion.
Therefore, after describing several embodiment, those skilled in the art will recognize that different changes, other structure, equivalent, can be used without and can deviate from essence of the present utility model.Accordingly, above description should not be regarded as the restriction of the determined the utility model scope of claim to such as beginning.
For example, although the visual indicator part described in above-mentioned embodiment indicates what be currently connected to mower to be power line (alternating current) battery by movement between the two positions.But those skilled in the art it is to be appreciated that according to actual needs, more indicating positions can also be configured for visual indicator part.For example, mower inserts two pieces of batteries simultaneously, visual indicator part can be mobile in the middle of three positions, comprises indicating the primary importance of current connection first battery, indicating the second place of current connection second battery and indicate the 3rd position of current connection alternating current.
In addition, in above-mentioned Fig. 4-Fig. 6, single key is shown, it both can insert the key socket corresponding to battery, can insert again the key socket corresponding to AC power, and therefore a key just can meet different power supply connection requests.But, in other embodiment, can also be respectively corresponding to the key socket of the AC power key different with the key jack configurations corresponding to battery, and both pin is incompatible.So, if user will use a certain power supply just the key corresponded must be inserted in key socket, thus user is avoided to obscure the connection of these two kinds of power supply types further.
Further, in two the key sockets 62,64 in the diagram, key socket 62 is described to be connected to battery, and key socket 64 is to AC outlet.But such setting can be specified arbitrarily according to user preferences completely.For example, in other embodiment, also both connections can be exchanged, make key socket 64 be configured to be connected to battery, and key socket 62 be connected to AC outlet.
