FIG. 3 is a view illustrating a state where a case body is detached from a battery case assembly for an electric bicycle according to an embodiment of the present invention. FIG. 4 is a perspective view of a battery case assembly for an electric bicycle according to an embodiment of the present invention. Fig. 2 is an enlarged view showing a state in which the case body is detached.

As shown in the figure, the battery case assembly 100 for an electric bicycle according to an embodiment of the present invention includes a case body 110 and a fixed body 150.

The case body 110 is configured to receive a battery for an electric bicycle used to supply power to the motor of the electric bicycle.

The fixed body 150 fixes the case body 110, which houses the battery for the electric bicycle, to the frame 10 of the electric bicycle, that is, the electric bicycle.

For this purpose, the fixed body 150 can be fixed on the frame 10 of the electric bicycle. The fixed body 150 is provided with a seating space 150a (see FIG. 6) having a shape corresponding to the case body 110 and the case body 110 is connected to the fixed body 150 through the seating space 150a And are fixed to the frame 10 in a sliding manner.

The case body 110 includes a housing portion 111 having a hollow in which a battery is housed and first and second covers 113 and 115 which are engaged with the openings at both ends of the housing portion 111. [

Preferably, at least one of the first and second covers (113, 115) formed in the case body (110) has a structure that can be opened and closed for battery replacement.

As a specific example, the first cover 113 is formed to be openable and closable from the storage portion 111, and one end of the storage portion 111 can be opened when the battery is replaced.

The fixing body 150 may be formed to include a seating member 151 (see FIG. 4) fixedly coupled in an L-shape through the frame 10 so as to be contacted with at least one side surface and a lower surface of the receiving portion 111 have.

More specifically, the seating member 151 (see FIG. 4) can be fixedly arranged in an L shape through a concave section section that is broken through the upper portion of the frame 10, and the side surface of the seating member 151 And the side surface and the lower surface of the case body 110 are contacted with each other through the bottom surface, so that a more stable connection state can be maintained even when the bicycle is moving.

With this structure, the case body 110 can be stably coupled to the fixed body 150 (more specifically, the seating pad 151) through the seating space 150a (see FIG. 6) in a sliding manner .

More specifically, as shown in FIG. 4, the other end (the rear end of the case body 110 shown in FIG. 4) of the case body 110 is connected to the other end (i.e., the rear end) Lt; / RTI > The terminal connecting portion 114 (see FIG. 7) provided at one end of the case body 110 slides into the seating space along the predetermined rotation direction (the opposite direction of the R direction) And can be connected to a connection terminal 153 provided in the terminal.

Here, the coupling relationship between the case body 110 and the fixed body 150 will be described with reference to FIGS. 5 to 7. FIG.

6 to 7, at one end of the case body 110, a first engaging groove (not shown) having a shape corresponding to a first step block 152 (see FIG. 6) protruded from one end of the fixed body 150, (See Fig. 7). 7) which is connected to the connection terminal 153 (see Fig. 6) is provided on the inner side of the first coupling groove 112 (see Fig. 7).

7) having a shape corresponding to the second step block 155 (see FIG. 6) protruded from the other end of the fixed body 150 is formed at the other end of the case body 110, Respectively. 6) formed in the longitudinal direction of the case body 110 through the second step block 155 (see FIG. 6) is inserted into the second coupling groove 116 (see FIG. 7) Detachment protrusion 117 is provided.

As described above, one end and the other end of the case body 110 are formed so as to correspond to one end and the other end of the fixing body 150, respectively, so that the other end of the case body 1100 is fixed to the fixing body 150 The connecting terminal 153 provided at one end of the fixed body 150 while rotating the terminal connecting portion 114 (see FIG. 7) provided at one end of the case body 110 in a state of being coupled to the other end of the fixed body 150 They can be connected and combined by a sliding method.

Meanwhile, one end of the case body 110 may further include a grip portion 120 (see FIG. 3) having a shape of a bar (or plate) that can be gripped.

The grip portion 120 refers to a member used to slide the case body 110 coupled to the fixed body 150 in a sliding manner.

For example, one end of the grip portion 120 may be connected to one end of the case body 110, and the other end of the grip portion 120 may be connected to the free end of the case body 110 in a detachable manner.

Thus, when the battery is detached and replaced, the operator grasps the grip portion 120 and pulls the case body 110 away from the fixed body 150 by pulling the grip body 120 in the direction opposite to the sliding direction (i.e., the R direction) .

The first cover 113 is coupled to one end of the case body 110 so as to cover the opening of the receiving portion 111 in which the battery is received. The upper and lower ends of the first cover 113 are bent at a predetermined angle . A linear protrusion 113a (see FIG. 4) protruding forward in a forward direction may be provided toward one end of the fixed body 150 at an inner portion (for example, a center portion of the height) of the first cover 113 formed by bending have.

According to the protruding shape of the linear protrusion 113a (see FIG. 4), the vertical depth of the case body 110, which is seated on the fixing body 150 when the case body 110 is engaged, can be stably limited. Accordingly, the case body 110 can be easily slidably coupled to a more accurate position on the fixing body 150. [

The first cover 113 may further include a protruding piece 113b protruding toward a side surface of the one end of the fixing body 150. [

The protruded piece 113b restricts the sliding position of the case body 110 when the case body 110 is slidably coupled to the seating space 150a of the fixed body 150 To be stable.

Further, a display 113c (see Fig. 5) may be further provided on the upper side of the first cover 113. [ The display 113c (see FIG. 5) is a means for visually displaying various information such as the remaining battery level, and is not limited to the shape shown in FIG. 5, and may have various other embodiments.

1 and 2, the locking part 170 may be further formed at one end of the fixed body 150. As shown in FIG.

1 and 2, a key is inserted through a lock hole 171 provided on the side surface of one end of the fixed body 150, and the fixed body 150 is rotated by the rotation of the inserted key, The lock bar (not shown) that flows from one end of the first cover 113 can be provided in a state of being locked and released through a lock groove (not shown) provided outside the first cover 113. The operation of locking and releasing the locking portion 170 is a widely known method. By operating the locking portion 170 thus configured, the locking between the locking body 150 and the case body 110 can be locked and / Can be released. As a result, it is possible to prevent the battery case as well as the battery case assembly from being lost or stolen.

As described above, according to the configuration and the operation of the present invention, the battery assembly for an electric bicycle having a structure capable of quickly and easily mounting the battery for an electric bicycle can be improved, and the novice user can easily Can be mounted.

Furthermore, there is an advantage that a separate lock device can be used to prevent the lost or stolen battery in use from being mounted on an electric bicycle.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
