Description

Battery slot and battery charging device including the same

[0001] The present invention relates to a battery slot and a battery charging device including the same.

[0002] Unlike primary batteries, secondary batteries can be recharged and discharged, making them suitable for a wide range of applications, including digital cameras, mobile phones, laptops, hybrid and electric vehicles, and aircraft. Secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, and nickel-hydrogen batteries, with lithium-ion batteries gaining widespread use recently.

[0003] In particular, the use of internal combustion engines for transportation is gradually decreasing, leading to a rise in demand for hybrid and electric vehicles. In line with this trend, demand for electric motorcycles and scooters, two-wheeled vehicles powered by electric motors used for short-distance travel, is also increasing, and the market for these vehicles is steadily expanding.

[0004] Traditionally, to charge the batteries of electric motorcycles, users either had to travel to a separate charging facility or connect a plug-in charger to the motorcycle. However, this approach required users to wait until the battery was fully charged, making driving impossible.

[0005] To address this issue, a battery charging device has been proposed that allows users to return used batteries and receive fully charged batteries.

[0006] For battery chargers like this, it is necessary to verify whether the returned battery is suitable for the battery charger.

[0007] The present invention was created in consideration of the above-described problems, and the problem that the present invention seeks to solve is to provide a battery slot that can determine whether a battery is suitable for a battery charging device through the structure of the battery, and a battery charging device including the same.

[0008] A battery slot according to the present invention comprises a slot frame that forms a receiving space into which a battery is inserted and includes an entrance formed by opening one side of the receiving space, a door coupled to the slot frame for opening and closing the entrance, a detection assembly coupled to the slot frame for detecting whether a battery is suitable for charging, and a control unit that sets the door to a locked or unlocked state based on information detected by the detection assembly, and the detection assembly may include a detection frame coupled to the slot frame and having an opening corresponding to the entrance, a detection button disposed on the detection frame that is pressed by the battery and moves as the battery enters the opening, and a detection unit that detects movement of the detection button.

[0009] The detection button is positioned on the inner side of the detection frame and can be configured to move in a direction perpendicular to the sliding movement direction of the battery as the battery slides along the inner side of the detection frame.

[0010] The outer surface of the detection button that comes into contact with the battery may be formed into a curved surface.

[0011] The detection buttons may be provided in multiple numbers and spaced apart along the perimeter of the opening.

[0012] The detection unit is configured to detect the number of detection buttons that have been moved by being pressed by the battery among a plurality of detection buttons, and the control unit can set the door to an unlocked state when the number of detection buttons detected by the detection unit is equal to or greater than a preset number.

[0013] The sensing frame further includes a button receiving groove that provides a movement space for the sensing button, and the sensing portion is disposed inside the button receiving groove so that the sensing button can be pressed as the sensing button moves inside the button receiving groove.

[0014] The sensing unit is configured to measure the pressure applied by the sensing button, and the control unit can set the door to an unlocked state when the pressure sensed by the sensing unit is higher than a preset reference pressure.

[0015] The sensing assembly may further include an elastic member connected to the button receiving groove and the sensing button, respectively, to provide elasticity to the sensing button.

[0016] The elastic member can be connected to both sides of the sensing button.

[0017] The battery slot may further include a locking member arranged adjacent to the doorway and configured to lock or unlock the door in response to a control signal from the control unit.

[0018] The battery slot further includes a charging terminal configured to be electrically connected to a battery inserted into the receiving space and capable of receiving an electrical signal from the battery, and the control unit can determine whether to start charging the battery based on the electrical signal of the battery received from the charging terminal.

[0019] The slot frame and the detection frame can be formed integrally.

[0020] The control unit can be configured to provide a voice guidance on the result of checking whether the battery is suitable through the voice module.

[0021] A battery charging device according to the present invention may include a battery slot according to the present invention.

[0022] According to one aspect of the present invention, the battery can be primarily confirmed through the structure of the battery. According to one aspect of the present invention, the battery can be primarily confirmed through the structure of the battery. If the battery inserted into the battery charging device is larger than a suitable battery, it cannot be inserted into the opening of the detection frame. Even if the battery is smaller, the detection button does not move completely due to the battery inserted into the opening of the detection frame, thereby failing to meet the preset standard, thereby preventing the insertion of an unsuitable battery into the battery slot. Therefore, since there is no need to include a display that provides battery information in the battery charging device, restrictions on the installation location of the battery charging device can be minimized.

[0023] According to another aspect of the present invention, after first confirming whether a battery is physically suitable through its structure, a second confirmation is made through a confirmation module to determine whether the battery is electrically suitable. This allows for a more accurate determination of whether the battery is suitable for a battery charging device.

However, the spirit of the present invention is not limited to the presented embodiments. For example, those skilled in the art who understand the spirit of the present invention may propose other embodiments within the spirit of the present invention by adding, modifying, or deleting components, etc., but such embodiments will also be considered within the spirit of the present invention. The shapes and sizes of elements in the drawings may be exaggerated for clarity.

[0037] Figure 1 is a drawing schematically showing a battery charging device (1) according to the present invention.

[0038] Referring to FIG. 1, a battery charging device (1) according to the present invention may include a battery slot (100) and a detection assembly (200).

[0039] A battery (10) can be inserted into the battery slot (100). The battery slot (100) can charge the inserted battery (10). The battery charging device (1) can include a plurality of battery slots (100). For example, the battery charging device (1) can include eight battery slots (100) arranged in four rows horizontally and two columns vertically. The user can receive a fully charged battery (10) from each battery slot (100) and return the existing battery (10) to the battery slot (100).

[0040] The detection assembly (200) can detect the insertion of the battery (10). The battery (10) can be inserted into the battery slot (100) through the detection assembly (200).

[0041] Figures 2 and 3 are drawings illustrating a process of inserting a battery (10) into a battery charging device (1) according to the present invention.

[0042] Referring to FIGS. 2 and 3, the battery slot (100) may include a slot frame (110), a door (120), a charging terminal (C), and a detection assembly (200).

[0043] The slot frame (110) can form a receiving space (S) into which a battery (10) is inserted. The slot frame (110) can include an entrance (I) formed by opening one side of the receiving space (S). The battery (10) can be inserted into the receiving space (S) or discharged from the receiving space (S) through the entrance (I). The slot frame (110) has a roughly rectangular box shape and can have an open shape at one end. The slot frame (110) can be equipped with a heat dissipation fan (not shown). The heat dissipation fan can be configured to discharge heat from the receiving space (S) to the outside.

[0044] A door (120) may be coupled to a slot frame (110). The door (120) may open and close an entrance (I) of the slot frame (110). The perimeter of the door (120) may coincide with the entrance (I) of the receiving space (S). The door (120) may be connected to the inner surface of the slot frame (110) through a connecting means such as a hinge and may be rotated. The door (120) may be configured to be rotatable within the receiving space (S). The door (120) may be selectively rotatable by a locking device (140) that controls the rotation of the door (120) according to an electrical signal. For example, the locking device (140) may be a catch that is arranged adjacent to the entrance (I) and restricts the rotation of the door (120) on the opposite side of the rotation axis, and the locking device (140) may be operated according to an electrical signal of a control unit (300) to be described later. The locking device (140) can determine whether the door (120) can rotate depending on the operation of the actuator. If the locking device (140) protrudes into the receiving space as shown in FIG. 2, the door (120) may not rotate so that the battery (10) cannot be inserted into the receiving space (S). If the locking device (140) does not protrude into the receiving space as shown in FIG. 3, the door (120) can rotate within the receiving space (S) by insertion of the battery (10).

[0045] However, the specific structure of the locking device (140) is not limited to that shown in FIG. 2, and can be formed with any structure as long as the movement of the door (120) can be appropriately restricted according to the door lock signal of the control unit (300).

[0046] The charging terminal (C) can be electrically connected to the battery (10) inserted into the receiving space (S). The charging terminal (C) can be exposed inside the receiving space (S). A connector configured to be connected to the charging terminal (C) can be provided on one side of the battery (10).

[0047] Fig. 4 is a perspective view showing a detection assembly (200) included in a battery slot (100) according to the present invention. Fig. 5 is a front view showing a detection assembly (200) included in a battery slot (100) according to the present invention. Fig. 6 is a drawing showing a battery (10) inserted into a detection assembly (200) included in a battery slot (100) according to the present invention.

[0048] Referring to FIGS. 4 to 6, the detection assembly (200) will be described in more detail.

[0049] The detection assembly (200) may include a detection frame (210), a detection button (220), and a detection unit (A).

[0050] The detection frame (210) can be coupled to the battery slot (100). The detection frame (210) can be coupled to the battery slot (100) on the side where the entrance (I) of the battery slot (100) is provided. The detection frame (210) can be provided with an opening (O) corresponding to the entrance (I) of the battery slot (100). The opening (O) can correspond to the shape of the battery (10). For example, when the battery (10) is a rectangular parallelepiped, the opening (O) can be a square shape corresponding to the bottom or cross-section of the rectangular parallelepiped. The battery (10) can be inserted into the receiving space (S) of the battery slot (100) by passing through the opening (O) of the detection assembly (200) and the entrance (I) of the battery slot (100).

[0051] In embodiments, the detection frame (210) may be formed integrally with the slot frame (110) of the battery slot (100) and may constitute a portion of the outer shape of the battery slot (100). Alternatively, the detection frame (210) may be formed as a separate component distinct from the slot frame (110) of the battery slot (100) and may be coupled to the slot frame (110).

[0052] The detection button (220) may be positioned on the detection frame (210). The detection button (220) may be positioned on the inner side of the opening (O) of the detection frame (210). The detection button (220) may move in a direction perpendicular to the sliding movement direction of the battery (10) as the battery (10) is inserted into the battery slot (100) while sliding along the inner side of the detection frame (210).

[0053] The detection buttons (220) may be provided in multiple numbers and spaced apart along the perimeter of the opening (O). For example, if the opening (O) is rectangular, the detection buttons (220) may be provided on each of the four inner sides of the opening (O), and a plurality of detection buttons (220) may be provided on each of the four sides. For example, as illustrated in FIG. 5, the detection buttons (220) may be provided in total of 10, with three detection buttons (220) on each of the two inner sides of the opening (O) and two detection buttons (220) on each of the two inner sides.

[0054] The detection button (220) may have a curved or inclined outer surface that comes into contact with the battery (10) when the battery (10) is inserted. Accordingly, the detection button (220) can be gently pressed when the battery (10) is inserted, thereby minimizing damage.

[0055] The sensing unit (A) can detect the movement of the sensing button (220). The sensing unit (A) may be a sensor mounted inside the sensing button (220). For example, the sensing button (220) may have an empty interior made of rubber or sponge material, and the sensing unit (A) may be mounted and inserted into the empty interior space of the sensing button (220) to detect when the sensing button (220) is pressed by a battery (10). The sensing unit (A) may detect the movement of the sensing button (220) that is pressed by the battery (10) and moves in a direction from the inner surface (210S1) of the sensing frame (210) toward the outer surface (220S2). The sensing unit (A) may detect the number of sensing buttons (220) that are pressed by the battery (10) and move among a plurality of sensing buttons (220). The sensing unit (A) can measure the pressure applied by the sensing button (220). The sensing unit (A) may be a sensor housed inside the sensing button (220). The sensor may be a motion detection sensor that senses the movement of the sensing button (220) or a pressure measurement sensor configured to measure the pressure applied by the sensing button (220).

[0056] Referring again to FIGS. 2 and 3, the battery slot (100) may include a control unit (300).

[0057] The control unit (300) can set the door (120) to a locked state based on the information detected by the detection assembly (200). The control unit (300) can set the door (120) to an unlocked state based on the information detected by the detection assembly (200). The control unit (300) can control the movement of the locking device (140). The control unit (300) can be arranged at one end of the slot frame (210). The control unit (300) can include an electronic circuit. The control unit (300) can include a communication unit. The control unit (300) can electrically obtain a detection signal of the detection unit (A). The control unit (300) can be electrically connected to an actuator that drives the locking device (140). The control unit (300) can set the door (120) to an unlocked state by operating the locking device (140) when the number of detection buttons (220) detected by the detection unit (A) is greater than or equal to a preset number. For example, when the detection unit (A) detects movement of 9 detection buttons (220) out of 10 detection buttons (220) due to insertion of the battery (10), the control unit (300) can set the door (120) to be rotatable by operating the locking device (140) so that it does not protrude into the receiving space. The control unit (300) can set the door (120) to an unlocked state by operating the locking device (140) when the pressure detected by the detection unit (A) is a preset reference pressure. The preset reference pressure may be a reference pressure that all of the pressures applied by each detection button (220) must exceed. Alternatively, the preset reference pressure may be a reference pressure that the sum of all pressures applied by each detection button (220) must exceed.

[0058] According to this configuration of the present invention, the battery charging device (1) can check whether the battery is suitable for the battery charging device (1) through the structure of the battery (10). Battery replacement in the battery charging device (1) can be performed by the user. Since a battery that is not suitable for the battery charging device (1) may be inserted due to a user's mistake or error, it is essential to check the battery in the battery charging device (1). This battery check can be performed by various methods such as NFC, QR code, etc., and in the case of these methods, an NFC recognition device, a QR code recognition camera, etc. may need to be included in the battery charging device. In particular, a display that provides guidance on the corresponding information may need to be included in the battery charging device or battery, which may restrict the installation location of the battery charging device.

[0059] However, the battery charging device (1) of the present invention may not be equipped with a display (monitor). The battery charging device (1) can primarily check the battery through the structure of the battery (10). If the battery (10) inserted into the battery charging device (1) is larger than a suitable battery, it cannot be inserted into the opening (O) of the detection frame (210). Even if the battery (10) is smaller, the detection button (220) may not move completely due to the battery inserted into the opening (O) of the detection frame (210), thereby not meeting the preset standard, thereby preventing the insertion of an unsuitable battery into the battery slot (100). Therefore, since the battery charging device (1) according to the present invention does not have a display, restrictions on the installation location of the battery charging device (1) can be minimized.

[0060] The control unit (300) may be configured to be electrically connected to the battery (10) to determine whether it is a suitable battery. The control unit (300) may be configured to selectively supply power to the charging terminal (C). The control unit (300) may be electrically connected to the inserted battery (10) through the charging terminal (C) to check the BMS of the battery (10) to obtain battery (10) information. The control unit (300) may send the battery information obtained by checking the BMS to the server to determine whether it is a suitable battery (10).

[0061] The charging terminal (C) of the battery charging device (1) may be configured to transmit and receive electric signals to and from the battery (10). The charging terminal (C) may transmit an electric signal received from the battery (10) to the control unit (300), and the control unit (300) may determine whether the inserted battery (10) is a battery suitable for charging based on the electric signal of the battery (10) received from the charging terminal (C), and may determine whether to start charging of the battery (10). For example, if the electric signal received from the battery (10) is different from the electric signal of a suitable battery that meets the charging specifications, the control unit (300) may determine that the inserted battery (10) is not suitable for charging, and may not start charging. Alternatively, if the electric signal received from the battery (10) is identical to the electric signal of a suitable battery that meets the charging specifications, the control unit (300) determines that the inserted battery (10) is suitable for charging, and supplies charging power to the battery (10) through the charging terminal (C) to start charging the battery (10).

[0062] That is, the control unit (300) determines whether the inserted battery (10) is suitable for charging through the charging terminal (C) electrically connected to the battery (10), and if it is a suitable battery (10), it can supply charging power to the charging terminal (C), and if it is an unsuitable battery (10), it can not supply charging power to the charging terminal (C).

[0063] Accordingly, after first confirming whether the battery (10) is physically suitable through the structure of the battery (10), it can be secondarily confirmed whether the battery (10) is electrically suitable through the confirmation module. It is possible to more accurately confirm whether the battery (10) is suitable for the battery charging device (1).

[0064] In embodiments, the battery charging device (1) may further include a voice module (not shown) configured to transmit a voice guidance message to the user. The control unit (300) may control the voice module (not shown) to provide a voice guidance on the result of the battery suitability check. If the result of the check is a suitable battery, the control unit (300) may control the voice module (not shown) to provide a voice guidance to the user that the battery is suitable and may provide guidance on the result of the charging process. If the result of the check is an unsuitable battery, the control unit (300) may control the voice module (not shown) to provide a voice guidance to the user that the battery is unsuitable and provide guidance on the result of prohibiting the charging process.

[0065] Fig. 7 is a schematic cross-sectional view of a detection assembly (203) included in a battery charging device (1) according to the present invention. Fig. 8 is a schematic cross-sectional view of a state in which a battery (10) is inserted into a detection assembly (203) included in a battery charging device (1) according to the present invention.

[0066] Referring to FIGS. 7 and 8, the sensing frame (210) may further include a button receiving groove (240). The sensing assembly (203) may further include an elastic member (250).

[0067] The button receiving groove (240) can provide a movement space for the detection button (220). The button receiving groove (240) can provide a movement space for the detection button (220) to move in a direction from the inner surface of the detection frame (210) to the outer surface and in the opposite direction. The button receiving groove (240) can be a groove formed on the inner surface of the detection frame (210). A detection unit (A) can be received on the inner side of the button receiving groove. The detection button (220) can protrude outward from the button receiving groove (240) before the battery (10) is inserted. When the battery (10) is inserted, the detection button (220) is pressed by the battery (10) and moves toward the inner side of the button receiving groove (240). The sensing unit (A) can be pressed by the sensing button (220) as the sensing button (220) is pressed by the battery (10) and moves toward the inside of the button receiving groove (240). Accordingly, the sensing unit (A) can detect the movement of the sensing button (220) inserted into the button receiving groove (240).

[0068] The elastic member (250) can be connected to the button receiving groove (240) and the detection button (220), respectively. The elastic member (250) can provide elastic force to the detection button (220) in a direction parallel to the movement direction of the detection button (220).

[0069] In a situation where no external force is applied to the detection button (220) by the battery (10), the elastic member (250) can apply elastic force to the detection button (220) so that the detection button (220) protrudes out of the button receiving groove (240).

[0070] A plurality of elastic members (250) may be provided on the inside of a single button receiving groove (240). For example, referring to FIGS. 7 and 8, a plurality of elastic members (250) may be spaced apart in a direction parallel to the inner surface (opposite the outer surface formed by the curved surface) of the detection button (220) to elastically support the inner surface of the detection button (220).

[0071] The sensing unit (A) may be arranged between a plurality of elastic members (250). For example, referring to FIGS. 7 and 8, the plurality of elastic members (250) may elastically support both edge areas of the inner surface of the sensing button (220), and the sensing unit (A) may be arranged to face the central area of ​​the inner surface of the sensing button (220).

[0072] According to this arrangement structure, the elastic member (250) can stably apply elastic force to the detection button (220), so that the detection button (220) can stably slide back and forth inside the button receiving groove (240) according to the insertion and removal of the battery (10), and the detection part (A) arranged between the elastic members (250) can stably detect the movement of the detection button (220) and the pressure applied by the detection button (220).

[0073] While the present invention has been described with reference to the accompanying drawings, focusing on preferred embodiments, it will be apparent to those skilled in the art that numerous obvious modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should be construed as encompassing the many examples of such modifications within the scope of the claims.
