Description

Battery charging device

The invention relates to a battery charging device.

With the rising awareness of environmental protection, electric vehicles that can save energy, reduce carbon emissions, reduce noise, and improve the efficiency of energy consumption are the energy-saving trends of today's social transportation, to replace gasoline with electricity and reduce air pollution caused by burning gasoline.

The endurance of conventional electric vehicles relies on the power provided by the on-board battery. Therefore, they must go to the charging station to charge or exchange the battery every time they travel a certain distance.

Furthermore, the battery specifications applicable to each brand of electric vehicles are different, for example, the voltage may be 12V, 48V or other, so a single specification battery cannot be applied to various electric vehicles. At the same time, in response to the differences in battery connectors for electric vehicles, a conservative and safe approach is for each brand to serve its own batteries. As a result, the user must spend time looking for a specific charging station to replace the battery. Therefore, it often happens that the electric vehicle has no power before reaching the charging station, which causes inconvenience in use and greatly reduces the practicality.

In addition, batteries are also commonly used as power sources in general households or production devices, so they are also faced with situations where they need to be charged or replaced. If there is no corresponding facility, it will also cause inconvenience to users and reduce the utility of the battery.

The invention provides a battery charging device, which simplifies the manual charging process of the battery by the user through the linkage assembly. At the same time, by adjusting the configuration of the components in the box, it will be suitable for batteries of different specifications.

The battery charging device of the present invention includes a box body, a door, a power source and a linkage assembly. The door is assembled to the box body to open and close relative to the box body. The battery is suitable for being placed in the box. The power supply has at least one first connector, which is arranged in the box. The linkage component is arranged on the box body and is located on the moving path of the door. The door is closed relative to the box body, and the interlocking component drives the battery and the first connector to move relative to each other, so as to connect the second connector of the battery to the first connector.

Based on the above, through the combination of the door and the interlocking component, the battery placed in the box can move relative to the first connector provided in the box by the interlocking component when the door is closed. The second connector can be connected to the first connector, and the power supply can smoothly charge the battery. This allows the user to complete the preparation before charging the battery by simply putting the battery into the box and closing the door and repositioning it.

By adjusting the configuration of the components, the user can use the box charged at home to achieve the purpose of charging the battery for personal use, and placing the box of the charging device in an outdoor environment can also achieve the purpose of sharing with people. In addition, in response to a variety of existing batteries of different specifications, the battery charging device can correspond to the batteries of different specifications moved into the box by arranging the connectors of different specifications in the linkage assembly, in addition to smoothly connecting the battery to the first battery during the movement process. The connectors avoid each other, and after the battery is moved into the box, the second connector of the battery can be aligned with the first connector corresponding to its specification. Accordingly, the battery charging device integrates a variety of connectors of different specifications into one, and can smoothly achieve the effect of sharing the charging device.

In other words, the battery charging device can integrate the existing technology, and by adjusting the configuration of the components in the box, it can incorporate various types of batteries into the same box to form a shared platform for charging and exchanging multiple types of batteries. Even if a new type of battery is added in the future, the newly added battery can be adjusted and integrated into the existing battery charging exchange sharing platform.

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

FIG. 1 is a schematic diagram of a battery charging device according to an embodiment of the invention. FIG. 2 is a schematic diagram of some components of the battery charging device of FIG. 1. At the same time, right-angle coordinates X-Y-Z are provided to facilitate component description. Please refer to FIGS. 1 and 2 at the same time. In this embodiment, the battery charging device 100, especially the battery charging device of an electric vehicle, includes a box body 110, a door 120, a power source 130, a linkage assembly 140, a bearing 150, Positioning assembly 160 and rail 180. The door 120 is assembled to the box body 110 to be opened and closed relative to the box body 110. The linkage assembly 140 is movably arranged in the box 110 to transmit force and change the direction of force transmission. The first connector 131 shown in FIGS. 1 and 2 is connected from the power supply 130 and penetrates into the box 110, and is disposed in the box 110. The output end of the linkage assembly 140 moves with the linkage assembly 140 in the box body 110, and the receiving end of the linkage assembly 140 is located on the moving path of the door 120 when the door 120 is closed relative to the box body 110. The rail 180 is disposed in the box body 110, the bearing 150 is slidably coupled to the rail 180, and the bearing 150 is used to place the battery 200A of the electric vehicle. As shown in Figure 1, the user first pulls the holder 150 out of the box 110, and waits for the battery 200A to be placed on the holder 150 and positioned on the holder 150 by the positioning assembly 160, and then the holder 150 and its The battery 200A is pushed into the box 110 as shown in FIG. 2. Here, in FIG. 1, in order to clearly identify the internal structural features of the box body 110, the box body 110 is shown in dashed lines instead, in which the positioning component 160 provides the required position limiting (positioning) function for the battery 200A. It should be noted that although the battery 200A of the electric vehicle is taken as an example here, the type of the battery is not limited due to this. For example, the well-known lead-acid batteries, lithium batteries, fuel cells, etc., and even new types of batteries that are subsequently developed, for those who need to charge or exchange batteries, can be applied to the battery charging device 100 of this embodiment. In other words, the battery charging device 100 is intended to provide a required charging service or exchange service for a user who can carry a battery or a battery that can be carried on a vehicle.

1 and 2 again, in this embodiment, the positioning assembly 160 includes a coordinate wall 161 and a plurality of positioning members 162, 163, wherein the coordinate wall 161 is disposed on the bearing 150, and the positioning member 162 is adjustably disposed at On the coordinate wall 161, the positioning member 163 is adjustably disposed on the holder 150. With the adjustable characteristics of the positioning members 162 and 163, the battery 200A placed on the holder 150 can be positioned accordingly. For example, the battery 200A can abut against the coordinate wall 161 and the positioning member 162 on it to be positioned on the holder 150, which is equivalent to providing a positioning effect on the XY plane, that is, the connector of the battery 200A and the battery The connectors of the charging device 100 can be located on the same XY coordinates. In other words, the adjustable point contact positioning between the battery 200A and the holder 150 is adopted by the positioning component 160, as shown by the double arrow in the enlarged part of FIG. 1, so that the holder 150 can carry each of them accordingly. Different types of batteries.

FIG. 3A is a simple schematic diagram illustrating the diagonal movement of the battery into and out of the box from a top-view perspective. Please refer to FIG. 3A and compare FIG. 1 and FIG. 2 to show the moving state of the holder 150 and the battery 200A thereon. As shown in FIG. 3A, the power supply 130 has a plurality of first connectors 131, 132, and 133 to correspond to batteries of different specifications. At the same time, the track 180 is required to move the battery 200A into and out of the box 110. It can avoid interference with these first connectors 131, 132, 133. Accordingly, the moving axis of the bearing 150 caused by the rail 180 is limited to oblique entry and exit, that is, compared to the opening direction of the box 110 (the direction toward the negative Y axis in the figure is the reference for its orientation). The shaft) is an inclined way of in and out, so that no matter what battery specification is put on the bearing 150, it can smoothly pass through possible structural obstacles during the process of moving into the box 110. Here, the moving axis (Y-axis) of the socket 150 and the opening direction of the box 110 (the negative Y-axis direction) substantially form an angle θ1, and this is done by considering batteries of different specifications and their second connections. The position of the device is adjusted and integrated to integrate the movement path of the bearing 150 and the angle θ1 required to enter and exit the box 110 obliquely. It should be mentioned that the embodiments shown in FIG. 1 and FIG. 2 are in a state where the battery 200A and the first connector 131 are in compliance with each other's specifications.

Fig. 3B is a schematic diagram of the oblique movement of the battery relative to the box according to another embodiment of the present invention. Different from that shown in FIG. 3A, FIG. 3B illustrates another movement mode of diagonal entry and exit, which can also achieve the effect of avoiding structural interference between the battery and the connector when the bearing 150A moves. Here, when the door 120 is closed, the linkage assembly 140, the bearing 150 and the door 120 are aligned and positioned on the Y axis.

4A and 4B are simple side views of the battery charging device of FIG. 1. Please refer to FIGS. 4A and 4B at the same time. As shown in FIG. 4A, the socket 150 and the battery 200A on it are moved into the box 110 but the door 120 has not been closed in the box 110, and FIG. 4B shows the door 120 closed. Close to the state of the box 110. Please refer to FIG. 4A and FIG. 4B at the same time and compare FIG. 1 or FIG. 2. In this embodiment, the linkage assembly 140 includes a guide post 141, a linkage plate 142, a wedge module 143, and a universal push rod 144, wherein the guide post 141 is erected in the box body 110 along the Z axis, and is essentially arranged between the fixed plate 112 at the top of the box body 110 and the fixed plate 111 at the bottom of the box 110. The linkage plate 142 is movably coupled to the guide post 141, and the linkage plate 142 forms the output terminal of the aforementioned linkage assembly. A plurality of first connectors 131 to 133 extending from the power supply 130 are disposed on the interlocking plate 142 to move along the Z axis with the interlocking plate 142. It can be clearly seen from the figure that the distance between the fixed plate 112 and the interlocking plate 142 is increased from the distance d1 shown in FIG. 4A to the distance d2 shown in FIG. 4B due to the downward movement of the interlocking plate 142. This action is equivalent to that the distance between the universal push rod 144 and the entrance of the box 110 along the Y axis will increase from the distance T1 in FIG. 4A to the distance T2 in FIG. 4B.

The wedge module 143 includes a pair of wedge blocks 143a, 143b that slidably abut each other, wherein the wedge block 143b is connected to the linkage plate 142, and the universal push rod 144 is connected to the wedge block 143a, and it can be seen from the figure that the door 120 also has a protrusion Part 121, and the universal push rod 144 is located on the moving path of the protrusion 121, so the door 120 will push the universal push rod 144 along the Y axis during the process of closing the door 120 to the box body 110, so that the wedge block 143a is along the Y axis. The Y-axis pushes the wedge block 143b (in the direction of the positive Y-axis in the figure), and then moves the wedge block 143b and the linkage plate 142 along the Z-axis (in the direction of the negative Z-axis in the figure) to complete the linkage assembly 140 for force transmission and force change The function of the transfer direction. Here, the universal push rod 144 is regarded as the receiving end of the linkage assembly 140.

Based on the above, when the socket 150 and the battery 200A on it are moved into the box 110 for positioning, the second connector 210 of the battery 200A will move directly under the first connector 131 and face the first connector 131. Take the first connector 131 and the second connector 210 of the battery 200A that conform to each other's specifications as an example. After being moved into the box 110 and positioned, the coordinates of the first connector 131 and the second connector 210 on the XY plane are the same, that is, the first connector 131 and the second connector 210 The orthographic projection of a connector 131 on the battery 200A is consistent with the second connector 210. Therefore, when the door 120 is closed to the box 110, it will reach the first connector 131 according to the protrusion 121 of the door 120 and the linkage assembly 140. The linkage relationship allows the first connector 131 to be smoothly connected to the second connector 210, and the power supply 130 can charge the battery 200A.

Furthermore, the battery charging device 100 further includes a spring 171 sleeved on the guide post 141, and these springs 171 constantly drive the linkage plate 142 to move to the top of the box 110. In other words, when the aforementioned door 120 is closed to the box 110, the spring 171 will be deformed (stretched) due to the downward movement of the linkage plate 142. Therefore, once the charging is completed and the user opens the door 120, the spring 171 The elastic force can drive the linkage plate 142 to move up (towards the positive Z-axis direction) to reset the linkage plate 142 and the wedge module 143. At the same time, the universal push rod 144 can push the door 120 away from the box 110. The power of pushing the door 120 away from the box 110.

Fig. 4C is a partial enlarged view of the battery charging device of Fig. 4A. Please refer to FIG. 4C. It should be noted that, in addition to the labor-saving means required by the user to open the door, the present embodiment can also use the track 180 to allow the user to put the battery 200A into the box 110. It can also save effort. In this embodiment, the rail 180 has a drop along the gravity direction g, that is, the surface of the fixed plate 111 is inclined relative to the inner bottom surface of the box 110 (which is a horizontal plane), so that the rail 180 is at the opening of the box 110 ( The height at the right side of FIG. 4C) is higher than the height inside the box 110 (at the left side of FIG. 4C). As shown in FIG. 4C, the rail 180 has an angle relative to the horizontal plane (the XY plane in this embodiment). The inclined state of θ2 enables the holder 150 to move into the box 110 by gravity, thereby reducing the thrust required by the user to push the battery 200A into the box 110.

Fig. 5 shows a simple front view of a battery charging device according to another embodiment. Please refer to FIG. 5, where another battery 200B and the corresponding first connector 133 are taken as an example, and the battery 200B is positioned on the holder 150 by the positioning members 164 and 165. When the holder 150 After being moved into the box body 110 in an oblique way through the rail 180, the second connector 220 of the battery 200B is facing the first connector 133. The difference from the previous embodiment is that in the linkage assembly 440 of this embodiment, The spring 172 is sleeved on the guide post 141 and abuts between the linkage plate 142 and the stop portion 141 a of the guide post 141. The spring 172 constantly drives the linkage plate 142 to move to the top of the box 110. In other words, when the user closes the door 120 as shown in FIGS. 4A and 4B, the linkage plate 142 moves down to charge the battery 200B. The linkage plate 142 compresses the spring 172, so when the user opens the door 120 Then, the elastic force of the spring 172 can drive the interlocking plate 142 to reset and provide assistance for pushing away the door 120. At the same time, the linkage plate 142 of this embodiment uses a universal push rod 144 to change the force transmission direction.

FIG. 6 is a schematic diagram of the ejector rod of the battery charging device of FIG. 1. Please refer to FIG. 6, in this embodiment, taking the first connector 131 as an example, the linkage assembly 140 further includes an ejector rod 145, which is fixed on the upper fixing plate 112 and passes through the linkage plate 142 to extend toward the negative Z axis. , So that after the first connector 131 is connected to the second connector 210 and the charging is completed, the control module (not shown) of the battery charging device 100 drives the door 120 to open and moves the linkage plate 142 upward and drives the first connector 131 When moving away from the second connector 210, there is still mating friction between the two connectors, which will lift the battery 200A. At this time, the pushing force of the ejector rod 145 on the battery 200A can limit the battery 200A to the holder. 150 to prevent being lifted by the above-mentioned fitting friction force, so as to ensure that the first connector 131 is smoothly separated from the second connector 210.

Fig. 7 shows a simple front view of a battery charging device according to another embodiment. Please refer to FIG. 7, this embodiment integrates the relevant features of the previous embodiments, and those that are the same as the previous embodiments will not be repeated. The difference is that this embodiment uses a battery 200C of another specification as an example. Here, the battery 200C is positioned on the supporting plate 150 by the positioning members 166, 167, 168, and after being moved into the box body 110, the second connector 230 of the battery 200C is facing the first connector 132 of the power supply 130, The linkage plate 142 also uses the universal push rod 144 to change the force transmission direction to perform the butt charging of the two connectors.

FIG. 8 shows a schematic diagram of a battery charging cabinet according to another embodiment. In this embodiment, the battery charging cabinet 10 is actually an assembly of the aforementioned battery charging devices 100, that is, multiple battery charging devices 100 are assembled in the same rack at the same time, and the battery charging cabinet 10 is suitable for being arranged outside the home. The external environment can be used by users who need replacement or charging, thereby improving the sharing performance of most people.

FIG. 9A is a schematic diagram of a battery charging device according to another embodiment of the present invention. FIG. 9B is a partial schematic diagram of the battery charging device of FIG. 9A at the opening. FIG. 9C is a cross-sectional view of the battery charging device of FIG. 9A. Please refer to FIGS. 9A to 9C at the same time. In this embodiment, the battery charging device 300 includes a box 310, a door 320, at least one first connector 330, and a linkage assembly. Here, the linkage assembly includes a guide housing 312, a linkage plate 350, and a spring 371. The guide housing 312 is disposed on the box body 310 and forms a channel 311. The door 320 is assembled at the opening of the guide housing 312 so as to be opposite to the box body. 310 opened and closed. The power supply is omitted here, which can already be known from the power supply 130 of the foregoing embodiment, so only the required first connectors 331 and 332 are shown. Here, the linkage plate 350 has openings 351 and 352 to correspond to the first connectors 331 and 332, respectively. When the battery (not shown) is not inserted, the first connectors 331 and 332 are substantially located under the linkage plate 350. When the battery (not shown) is inserted, the second connector (not shown) of the battery is located above the openings 351 and 352, and is facing the first connector 331 or 332, and is opposite to the box 310 at the door 320 During the closing process, the door 320 uses the battery to drive the linkage plate 350 of the linkage assembly, so that the battery and the linkage plate 350 move toward the first connectors 331 and 332 until the first connector 331 or 332 passes through the openings 351 and 332. 352 is connected to the battery to allow the power source to charge the battery.

In another embodiment, if the shape of the battery is so special that it cannot be guided by contact with the wall surface of the guide shell 312, the XY axis adjustment bumps can also be provided on the wall surface, just like the coordinate wall in the previous embodiment. 161 and the positioning member 162 thereon, so that the wall surface of the guide shell 312 can be matched with the outer surface of the battery and achieve a positioning effect.

Furthermore, the linkage assembly of this embodiment is composed of a guide housing 312, a linkage plate 350, and a spring 371. The linkage plate 350 is movably disposed in the channel 311 of the guide housing 312, and the linkage plate 350 is movably disposed in the channel 311 of the guide housing 312. The profile is adapted to the inner profile of the channel 311 and can guide the linkage plate 350 to move in the channel 311. The spring 371 is connected between the linkage plate 350 and the box 310, and the spring 371 and the first connectors 331 and 332 are located in the channel 311, wherein the spring 371 constantly drives the linkage plate 350 to move toward the guiding shell 312 of the box 310. Furthermore, the first connectors 331 and 332 of this embodiment pass through the linkage plate 350, and when the battery is inserted into the channel 311 and move down with the linkage plate 350, they are connected to the first connectors 331 and 332 passing through the linkage plate 350. Can be connected to the battery smoothly.

In other words, when the battery is placed on the linkage plate 350, the user applies force to close the door 320, and the force can overcome the elastic force of the spring 371. Therefore, when the door 320 is closed, the battery and the linkage plate 350 will also be closed. Move into the box 310 along the guide shell 312 to achieve the effect of the aforementioned connector docking and starting charging. Conversely, when the user opens the door 320 and the applied force is zero, the elastic force of the spring 371 is released, and the spring 371 can drive the linkage plate 350 and the battery on it to protrude from the box 310 along the guide shell 312 to facilitate use The person recognizes and removes the battery.

The battery charging device 300 of this embodiment can also charge batteries of different specifications. Here, in addition to the first connectors 331 and 332 corresponding to batteries of different specifications, the channel 311 can also be adapted to the batteries of different specifications. Furthermore, the battery charging device 300 of this embodiment further includes a filler 340 disposed in the channel 311 to partition the channel 311 into different sub-spaces 311a, 311b, wherein the sub-spaces 311a, 311b are used to fit the Batteries of different specifications, and the sub-spaces 311a and 311b partially overlap each other. 9B and 9C are shown by the dashed cross-section line as the subspaces 311a and 311b. The corresponding positions of the subspaces 311a and 311b in the channel 311 can also represent the corresponding positions of the battery and other components after the battery is inserted into the channel 311. Here, the filler 340 may be additionally disposed in the channel 311, may be a simple insert or an integral structure with the box body 310.

Furthermore, the filler 340 of this embodiment can provide two sub-spaces 311a and 311b in the channel 311 for accommodating different types of batteries, which can be further inferred in other implementations not shown. For example, if properly adjusted, the filler can effectively provide at least two or more sub-spaces to adapt to multiple types of batteries. Conversely, after reasonable calculations, batteries of multiple types or sizes can change the space changes in the channel through the existence of fillers, so that the channel can be adapted to these different types or sizes through the filler. Battery.

In addition, in this embodiment, for the linkage plate 350 and the first connectors 331 and 332 that are also located in the channel 311, they can also provide different spatial changes corresponding to the aforementioned filler 340. For example, the linkage plate 350 of this embodiment forms a stepped structure, so that the lower one can adapt to the battery with the higher height, and the battery with the higher height naturally needs the channel 311 to provide a deeper depth. However, the battery with a higher step structure can be adapted to a battery with a lower height, and the battery with a lower height naturally requires the channel 311 to provide a shallow depth. Similarly, the length of the first connectors 331 and 332 can also be changed correspondingly according to the above conditions and the height of the stepped structure of the linkage plate 350. Based on the above, the filler 340, the linkage plate 350 and the first connectors 331, 332 can be adjusted appropriately according to the corresponding conditions of the battery (various types and multiple sizes), so as to achieve the integration of multiple types of batteries. Battery charging device 300.

In addition, as shown in FIG. 9A, unlike the previous embodiment, which is a movable first connector, this embodiment changes the second connector of the battery to move to the first connector, so the channel 311 is relative to gravity. The direction is inclined, that is, as shown in Figures 9A and 9C, so that the user can put the battery into the box 310. The orientation of the guide shell 312 of the box 310 is consistent with the axis Z1, which is in line with the direction of gravity. There is a tilt of angle θ3 between the axial directions (Z-axis).

FIG. 9D shows a schematic diagram of the spring and the battery in the battery charging device. Please refer to FIG. 9D, which represents the channel 311 (shown in FIGS. 9A to 9C) from left to right, the battery 200D has not been placed, the battery 200D has been placed, and the door 320 has been closed, in which the spring 371 has not been placed The battery 200D has a length d3. When the battery 200D is placed, it is reduced to a length d4. When the user closes the door 320 to close the guide housing 312, the door 320 drives the linkage plate 350 downward along the axis Z1 by the battery 200D Move (shown in Figure 9C) so that the battery 200D and the linkage plate 350 move to the first connector 331 or 332 until the first connector 331 or 332 is connected to the second connector (not shown) of the battery 200D. The power source charges the battery 200D, and at this time, the spring 371 is further compressed to a length d5, that is, length d3>length d4>length d5. Conversely, when the door 320 is opened after the charging is completed, the elastic force of the spring 371 can drive the battery 200D to move away from the first connector 331 or 332 by the linkage plate 350, and can further drive a part of the battery 200D to protrude from the box. Outside the guide shell 312 of the body 311, as shown in the center diagram of FIG. 9D, it can provide the battery 200D with a pushing stroke S1 to facilitate the user to identify and smoothly take the battery 200D out of the channel 311.

Furthermore, the battery charging device of this embodiment can also provide corresponding elastic springs according to the different weights of different types of batteries. It also takes the position of the closed door 320 as a reference to allow the door 320 to be opened. The elastic force generated by the spring can produce different pushing strokes in response to batteries of different weights.

FIG. 9E shows a partial schematic diagram of a battery charging device according to another embodiment. Similar to the battery charging device shown in FIGS. 9A to 9D above, but the difference is that the spring 371 is sleeved on the first connector 331 in this embodiment to reduce the space occupied by the component in the box 310, and the spring can also be provided. The deformation path that 371 can follow when deforming improves the stability of the linkage plate 350 when it moves.

FIG. 9F shows a partial top view of a battery charging device according to another embodiment. Please refer to FIG. 9F and compare to FIG. 9B. As mentioned above, the filler 340 divides the channel 311 into different sub-spaces 311a and 311b to adapt to batteries of different specifications (shapes). In this embodiment, the battery The charging device is replaced with a movable filler 341.
