Figure 2 is a perspective view showing a battery pack according to an embodiment of the present invention from below. Figure 3 is a side view of a battery pack according to an embodiment of the present invention.

[0057] A battery pack 100 according to an embodiment of the present invention is installed in a mechanism that requires power and supplies power to the mechanism. The battery pack 100 can provide the power, charging, and discharging capacity required by the mechanism. For example, the mechanism can be a robot, an electric vehicle, other power machines, etc.

[0058] Refer to Figures 1 to 3 , a battery pack 100 according to an embodiment of the present invention includes: a battery 110, a housing 120, and a connector 130.

[0059] The battery 110 generates electrical energy. The electrical energy generated by the battery 110 can be used as the power source for the mechanism in which the battery pack 100 is installed.

[0060] The battery 110 can be composed of a rechargeable and dischargeable secondary battery. For example, the battery 110 can be a lithium-ion battery, a lithium iron phosphate battery, etc. Of course, the type of the battery 110 should not be limited by the examples.

[0061] The housing 120 forms the appearance of the battery pack 100. In an embodiment of the present invention, the housing 120 can have a quadrilateral box shape. More specifically, the housing 120 can generally have a rectangular parallelepiped shape.

[0062] The housing 120 houses the battery 110. That is, the battery 110 can be disposed inside the housing 120. The housing 120 protects the battery 110 disposed inside from external impacts. In addition, the housing 120 prevents foreign substances such as moisture and dust from entering the battery 110.

[0063] The housing 120 can be a rigid body. For example, the housing 120 can include a metallic material.

[0064] In an embodiment of the present invention, the housing 120 includes: an upper portion 121, a lower portion 122, and a plurality of side portions 123, 124, 125, 126.

[0065] The upper portion 121 can have a horizontal plate shape. In an embodiment of the present invention, the upper portion 121 has a quadrilateral plate shape. More specifically, the upper portion 121 has a right-angled quadrilateral plate shape.

[0066] For Figure 1 explanation purposes, the upper portion 121 is disposed parallel to the XY plane.

[0067] The lower portion 122 is spaced below the upper portion 121 and is disposed facing the upper portion 121. The lower portion 122 can have a horizontal plate shape. In an embodiment of the present invention, the lower portion 122 has a quadrilateral plate shape. More specifically, the lower portion 122 has a right-angled quadrilateral plate shape.

[0068] For Figure 1 explanation purposes, the lower portion 122 is disposed parallel to the XY plane.

[0069] The plurality of side portions 123, 124, 125, 126 are disposed to connect the upper portion 121 and the lower portion 122. The plurality of side portions 123, 124, 125, 126 can form a closed area between the upper portion 121 and the lower portion 122. More specifically, the plurality of side portions 123, 124, 125, 126 can form a closed area in a quadrilateral box shape between the upper portion 121 and the lower portion 122.

[0070] In an embodiment of the present invention, the plurality of side portions 123, 124, 125, 126 can include: a first side portion 123, a second side portion 124, a third side portion 125, and a fourth side portion 126.

[0071] The first side portion 123 and the third side portion 125 extend along a first direction (a direction parallel to the X-axis in Figure 1 ). The first side portion 123 and the third side portion 125 can be disposed to face each other.

[0072] For Figure 1For the sake of explanation, the first side face 123 and the third side face 125 are configured to be parallel to the XZ plane.

[0073] The second side face 124 and the fourth side face 126 extend along a second direction orthogonal to the first direction (a direction parallel to the Y axis in Figure 1 this case). The second side face 124 and the fourth side face 126 can be configured to face each other.

[0074] For Figure 1 the sake of explanation, the second side face 124 and the fourth side face 126 are configured to be parallel to the YZ plane.

[0075] On the other hand, the first side face 123, the second side face 124, the third side face 125, and the fourth side face 126 can all have the same height.

[0076] One of the plurality of side faces 123, 124, 125, 126 may have a protruding structure in which the upper part protrudes more outward than the lower part. In one embodiment of the present invention, among the first side face 123, the second side face 124, the third side face 125, and the fourth side face 126, the first side face 123 may have a protruding structure in which the upper part protrudes more outward than the lower part.

[0077] The first side face 123 having the protruding structure includes: a lower side face 123a; an upper side face 123b, disposed at a position more outwardly protruding than the lower side face 123a; and a connecting face 123c, extending to connect the lower side face 123a and the upper side face 123b.

[0078] At this time, the connecting face 123c can be orthogonal to the lower side face 123a and the upper side face 123b respectively. In addition, the connecting face 123c can be disposed in parallel with the upper face 121 and the lower face 122.

[0079] For Figure 1 the sake of explanation, the lower side face 123a and the upper side face 123b are configured to be parallel to the XZ plane, and the connecting face 123c can be configured to be parallel to the XY plane.

[0080] The connector 130 connects the battery 110 to the outside. Through the connector 130, the power of the battery 110 can also be supplied to the outside.

[0081] It can also be that an external power source is supplied through the connector 130 in order to charge the battery 110. In addition, a control signal for managing the battery 110 can also be transmitted through the connector 130.

[0082] The connector 130 has terminals 131 for connecting the battery 110 to the outside and is connected to the housing 120. The connector 130 may further include a connector housing 132 configured to internally arrange the terminals 131. The connector housing 132 may be configured to surround the terminals 131.

[0083] The connector 130 may be configured to orient the terminals 131 downward. At this time, the connector housing 132 has an open lower side and may have a shape surrounding the sides of the terminals 131.

[0084] When the terminals 131 of the connector 130 have a downward orientation, the connector 130 can be easily fastened to the corresponding connector by the self - weight of the battery pack 100. That is, because the terminals 131 of the connector 130 have a downward orientation, the fastening of the connector 130 can be easily achieved by the self - weight of the battery pack 100.

[0085] The connector 130 can be arranged on one of the side faces having the protruding structure among the plurality of side faces 123, 124, 125, 126. In an embodiment of the present invention, the connector 130 is arranged on the first side face 123.

[0086] As described above, the first side face 123 includes: a lower side face 123a; an upper side face 123b arranged at a position more outwardly protruding than the lower side face 123a; and a connecting face 123c extending to connect the lower side face 123a and the upper side face 123b.

[0087] At this time, the connector 130 can be arranged on the connecting face 123c. More specifically, the connector 130 can be arranged at the center of the connecting face 123c.

[0088] The connector 130 may be configured to orient the terminals 131 downward on the connecting face 123c. Since the connecting face 123c is configured to be parallel to the upper face portion 121 and the lower face portion 122, when the connector 130 is arranged on the connecting face 123c, it is easy to orient the terminals 131 downward.

[0089] The extension portion 140 is configured to extend the upper face portion 121 of the housing 120 more outwardly than the plurality of side faces 123, 124, 125, 126. The extension portion 140 provides a structure in which the upper end of the battery pack 100 extends outwardly from the housing 120.

[0090] The extension portion 140 can fix and latch the battery pack 100 to the outside. When the battery pack 100 is inserted into the mounting opening arranged in a mechanism such as a robot, the extension portion 140 latches onto the frame of the mounting opening while fixing the battery pack 100.

[0091] In one embodiment of the present invention, the upper portion 121 has a quadrilateral plate shape, and the extension portion 140 extends more outward from each corner of the upper portion 121 than the first side portion 123, the second side portion 124, the third side portion 125, and the fourth side portion 126.

[0092] The extension portions 140 can be continuously arranged while surrounding the upper portion 121. In one embodiment of the present invention, the extension portions 140 can be arranged to entirely surround the upper portion 121 having a quadrilateral plate shape.

[0093] As described above, since the extension portions 140 are continuously arranged while surrounding the upper portion 121, when the battery pack 100 is installed in an external mechanism, a latching structure for the external mechanism is formed along the upper end of the housing 120 as a whole.

[0094] The extension portions 140 can extend from the upper portion 121 by a uniform distance. Since the extension portions 140 extend from the upper portion 121 by a uniform distance, when the battery pack 100 is installed in an external mechanism, it is possible to prevent the concentrated support force generated while being latched to the external mechanism from being concentrated on a specific portion of the extension portions 140.

[0095] By the structure in which the extension portions 140 entirely surround the upper portion 121 and the structure in which the extension portions 140 extend from the upper portion 121 by a uniform distance, the stress acting on the extension portions 140 is effectively dispersed. Accordingly, the durability of the battery pack 100 can be improved.

[0096] The extension portions 140 can be formed integrally with the housing 120. More specifically, the extension portions 140 can be formed integrally with the upper portion 121.

[0097] The extension portions 140 can be made of the same material as the housing 120. For example, the extension portions 140 can include a metal material.

[0098] Above, a detailed description has been given of the battery pack 100 according to one embodiment of the present invention. Hereinafter, a description will be given of the robot 1 according to one embodiment of the present invention.

[0099] Figure 4 It is a diagram showing the structure of a robot according to one embodiment of the present invention. Figure 5 It is a diagram showing a state in which a battery pack of a robot according to one embodiment of the present invention is separated.

[0100] The robot 1 according to one embodiment of the present invention can perform operations by receiving power from the battery pack 100. For example, the robot 1 can perform operations of moving a vehicle to be parked into a parking space or retrieving a vehicle parked in a parking space. More specifically, the robot 1 is configured to be low-profile and can move by lifting one or more wheels of a vehicle to be parked.

[0101] Reference Figure 4 and Figure 5 Figure 5 According to one embodiment of the present invention, the robot 1 includes a battery pack 100 and a main body 200.

[0102] The battery pack 100 includes: a battery 110, a housing 120, a connector 130, and an extension portion 140.

[0103] The battery 110, the housing 120, the connector 130, and the extension portion 140 are the same as the relevant descriptions of the battery pack 100 according to one embodiment of the present invention. Therefore, regarding the battery pack 100, the detailed description of each structure will be omitted.

[0104] The main body 200 forms the skeleton of the robot 1. The main body 200 may include one or more main body members 210. For example, the main body member 210 may be a bracket, a plate, etc.

[0105] The main body 200 may have an overall plate shape. As described above, the robot 1 is configured to be low-profile to perform the operation of lifting and moving the wheels of a vehicle. For this purpose, the robot 1 should enter the lower part of the vehicle. In this regard, the main body 200 may have a plate shape.

[0106] Based on Figure 4 the main body 200 has a shape that expands in a plane parallel to the XY plane.

[0107] The battery pack 100 is installed on the main body 200. As Figure 5 shown, the main body 200 has an installation opening 220 for installing the battery pack 100.

[0108] The installation opening 220 is open at the upper side. Accordingly, when the battery pack 100 is inserted into the installation opening 220, the extension portion 140 is caught in the upper corner 221 of the frame of the installation opening 220, and thus the battery pack 100 can be fixed to the main body 200. That is to say, the extension portion 140 hangs on the frame of the installation opening 220, and thus the battery pack 100 can be fixed to the main body 200 by its own weight.

[0109] The installation opening 220 may have a shape corresponding to the shape of the housing 120 of the battery pack 100. As described above, the housing 120 of the battery pack 100 may have a quadrilateral box shape, and the installation opening 220 may have a corresponding quadrilateral box shape.

[0110] The installation opening 220 may have a shape that penetrates vertically. Differently, the installation opening 220 may also have a structure with a closed lower end.

[0111] In an embodiment of the present invention, the extension portion 140 of the battery pack 100 is continuously arranged while surrounding the upper surface portion 121 of the housing 120 of the battery pack 100. More specifically, the extension portion 140 can be arranged to entirely surround the upper surface portion 121 in the shape of a quadrilateral plate.

[0112] Accordingly, the entire battery pack 100 is stuck in the upper corner 221 of the frame of the mounting opening 220 and fixed to the main body 200. Due to this structure, the battery pack 100 can be stably fixed to the main body 200.

[0113] In addition, in an embodiment of the present invention, the extension portion 140 of the battery pack 100 can extend a uniform length from the upper surface portion 121. Accordingly, the extension portion 140 stuck in the upper corner 221 of the frame of the mounting opening 220 can effectively disperse stress.

[0114] As described above, the structure in which the extension portion 140 is arranged to entirely surround the upper surface portion 121 and thus entirely stuck in the upper corner 221 of the frame of the mounting opening 220, and the structure in which the extension portion 140 extends a uniform length from the upper surface portion 121 to be uniformly stuck in the upper corner 221 of the frame of the mounting opening 220 are for effectively dispersing the stress acting on the extension portion 140 when the battery pack 100 is mounted on the main body 200 of the robot 1. Accordingly, the durability of the battery pack 100 can be improved.

[0115] At least a part of the upper corner 221 of the frame of the mounting opening 220 in contact with the extension portion 140 is lower than the outside with respect to the mounting opening 220. For example, at least a part of the upper corner 221 of the frame of the mounting opening 220 can be formed to be lower than the outside by more than the thickness of the extension portion 140 with respect to the mounting opening 220.

[0116] In an embodiment of the present invention, the entire upper corner 221 of the frame of the mounting opening 220 in contact with the extension portion 140 is formed to be lower than the outside by about the thickness of the extension portion 140 with respect to the mounting opening 220. Accordingly, when the battery pack 100 is inserted into the mounting opening 220 and mounted on the main body 200, there is no increase in height (with respect to Figure 4 as a reference, the length in the Z-axis direction increases).

[0117] A corresponding connector 230 is arranged on the main body 200. The corresponding connector 230 can be fastened to the connector 130 of the battery pack 100.

[0118] In an embodiment of the present invention, the corresponding connector 230 can be arranged inside the mounting opening 220.

[0119] Figure 6 It is a diagram showing a corresponding connector arranged on the main body of a robot according to an embodiment of the present invention.

[0120] Refer toFigure 6 , the corresponding connector 230 has corresponding terminals 231, and the corresponding terminals 231 are connected to the terminals 131 of the connector 130 of the battery pack 100. Additionally, the corresponding connector 230 may further include a corresponding connector housing 232, and the corresponding connector housing 232 is configured to internally dispose the corresponding terminals 231. The corresponding connector housing 232 may be configured to surround the terminals 231.

[0121] The corresponding connector 230 may be configured to orient the corresponding terminals 231 upward. At this time, the corresponding connector housing 232 has an open upper side and may have a configuration surrounding the sides of the corresponding terminals 231.

[0122] On the other hand, as described above, the connector 130 of the battery pack 100 may be configured to orient the terminals 131 downward. Therefore, when the corresponding connector 230 is configured such that the corresponding terminals 231 face upward, it is possible to easily achieve fastening of the connector 130 and the corresponding connector 230 by the self-weight of the battery pack 100 when the battery pack 100 is installed.

[0123] Figure 7 FIG. is a view showing a state before inserting the battery pack into the mounting opening of the main body of the robot according to an embodiment of the present invention. Figure 8 FIG. is a view showing a state of inserting the battery pack into the mounting opening of the main body of the robot according to an embodiment of the present invention.

[0124] Refer to Figure 7 and Figure 8 , the terminals 131 of the connector 130 of the battery pack 100 face downward, and the corresponding terminals 231 of the corresponding connector 230 face upward. Therefore, when the battery pack 100 is inserted into the mounting opening 220, the connector 130 and the corresponding connector 230 can be fastened by the self-weight of the battery pack 100.

[0125] On the other hand, when separating the battery pack 100 from the main body 200 of the robot 1, the connector 130 and the corresponding connector 230 can be separated from each other by the force of lifting the battery pack 100. That is, according to an embodiment of the present invention, the connector 130 and the corresponding connector 230 can be naturally fastened and separated during the installation or separation process of the battery pack 100.

[0126] The robot 1 provides the detachable structure of the connector 130 and the corresponding connector 230 as described above.
