Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a charging device and a vehicle. Background Technology

[0002] In related technologies, when using a charging device to charge a device, it is difficult to accurately reflect the charging status of the device to be charged. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide a charging device and a vehicle that can more accurately reflect the charging status of the device to be charged.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] One embodiment of this application discloses a charging device, including:

[0006] A charging module is used to provide electrical energy to the device being charged.

[0007] A control module is connected to the charging module, and the control module is able to obtain the output power of the charging module;

[0008] A Bluetooth module is connected to the control module. The Bluetooth module can connect to the device to be charged via Bluetooth to obtain the power level of the device to be charged.

[0009] A display module is connected to the control module, and the display module is used to display the charging status of the device to be charged.

[0010] In one embodiment, the charging module is a wireless charging module.

[0011] In one embodiment, the charging device includes a circuit board, and the charging module, the control module, the Bluetooth module and the display module are all connected to the circuit board. The display module includes a plurality of indicator lights arranged along a first direction. The circuit board can control the plurality of indicator lights to light up sequentially along the first direction according to the charging status of the device to be charged.

[0012] In one embodiment, the indicator light has a flashing state and a constant state after being lit. The circuit board controls the number of flashing and / or constant state of the multiple indicator lights to indicate that the device to be charged has different levels of power.

[0013] In one embodiment, the charging device includes:

[0014] The housing has a receiving cavity and a mounting port communicating with the receiving cavity, and both the wireless charging module and the display module are disposed in the receiving cavity;

[0015] A cover is provided on the mounting port, and the surface of the cover is provided with a light-transmitting mask.

[0016] In one embodiment, the face mask is made of polycarbonate; and / or,

[0017] The face mask is connected to the cover via two-color injection molding; and / or,

[0018] The housing and the cover are detachably connected.

[0019] In one embodiment, the charging device includes a diffuser located in the receiving cavity and disposed between the display module and the face mask.

[0020] In one embodiment, the diffuser is connected to the face mask using optical adhesive; and / or, the charging device includes a light guide located in the receiving cavity and disposed between the indicator light and the diffuser.

[0021] Another aspect of this application discloses a vehicle that includes the charging device described in any of the above embodiments.

[0022] In one embodiment, the control module is a vehicle body controller.

[0023] This application discloses a charging device and a vehicle, which acquire power information in two ways. Firstly, the output power of the charging module can provide feedback on the charging completion status of the device being charged. For example, a low output power indicates that the charging module is trickle-charging the device, and the device may be fully charged or nearly fully charged. A high output power indicates that the device's power is low, and the charging module is charging it at high power. Using output power as a criterion improves the accuracy of charging completion. Secondly, the power level of the device being charged is acquired via a Bluetooth module. This not only provides a more accurate assessment of the device's current power level but also reduces reliance on network signals, allowing for stable and direct acquisition of power information even in environments with weak signals. This provides good anti-interference capabilities and high power level recognition accuracy. A display module connected to the control module displays the charging status of the device, reducing the risk of accidents caused by turning on the device's screen while driving to check the charging status, thus improving safety.

[0030] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] One embodiment of this application provides a charging device 100, applied to a vehicle. Please refer to [link / reference]. Figures 1 to 4 The charging device 100 includes a charging module 1, a control module, a Bluetooth module, and a display module. The charging module 1 provides power to the device to be charged. The control module is connected to the charging module 1 and can acquire the output power of the charging module 1. The Bluetooth module is connected to the control module and can establish a Bluetooth connection with the device to be charged to obtain the device's power level. The display module 3 is connected to the control module and displays the charging status of the device to be charged.

[0033] The device to be charged can be a mobile phone, earphones, or tablet, or any other device that can be wirelessly charged.

[0034] The control module is connected to the charging module 1, the Bluetooth module is connected to the control module, and the display module 3 is connected to the control module. The connection can be wired or wireless.

[0035] The display module 3 is connected to the control module and is used to display the charging status of the device to be charged. This means that the display module 3 can provide feedback on the charging status through the output power obtained by the control module and the power obtained by the Bluetooth module.

[0036] Display module 3 refers to the ability to display the charging status, for example, through the color and number of lights or a display screen, etc.

[0037] The control module can perform time integration on the output power to obtain the input energy value, and establish a correspondence table between energy and power based on the nominal energy of the battery of the device to be charged. Based on the obtained energy, the relevant power information is obtained through the correspondence table and then transmitted to the display module.

[0038] The charging device 100 provided in this application provides power to the device to be charged through the charging module 1. The control module obtains the output power of the charging module 1 by connecting to the charging module 1, while the Bluetooth module obtains the current power level of the device to be charged through Bluetooth transmission. On the one hand, the output power of the charging module 1 can provide feedback on the charging completion status of the device to be charged. For example, when the output power is low, it means that the charging module 1 is trickle charging the device to be charged, and the power level may be fully charged or close to fully charged. When the output power is high, it means that the power level of the device to be charged is low, and the charging module 1 is charging the device to be charged with high power. In this way, using the output power as a judgment criterion can improve the accuracy of charging completion. On the other hand, obtaining the power level of the device to be charged through the Bluetooth module can not only obtain the current power level of the device to be charged more accurately, but also reduce the dependence on network signals through Bluetooth transmission. This allows for stable and direct acquisition of power information even in environments with weak signals, with good anti-interference ability and power identification accuracy. The display module 3 is connected to the control module to display the charging status of the device to be charged. This reduces the safety risks caused by turning on the screen of the device to be charged while driving in order to know the charging status, thus improving safety.

[0039] The charging device 100 provided in this application primarily relies on the output power feedback obtained by the control module, supplemented by feedback from the Bluetooth module. When both the control module and the Bluetooth module can obtain power information, the feedback from the control module takes precedence, which can improve the accuracy of charging completion. When the control module cannot obtain power information but the Bluetooth module can, the feedback from the Bluetooth module takes precedence, which can improve the accuracy of power identification.

[0040] In one embodiment, the charging module 1 is a wireless charging module.

[0041] Here, by setting the charging module 1 as a wireless charging module, the device to be charged can be charged without a charging cable, which is highly portable.

[0042] In one embodiment, the charging device 100 includes a circuit board 2, and a charging module 1, a control module, a Bluetooth module, and a display module 3 are all connected to the circuit board. The display module 3 includes multiple indicator lights 31 arranged along a first direction. The circuit board 2 can control the multiple indicator lights 31 to illuminate sequentially along the first direction according to the charging status of the device to be charged.

[0043] Circuit board 2 can be a PCBA (Printed Circuit Board Assembly). The control module can communicate with circuit board 2 via a data bus (such as CAN).

[0044] The Bluetooth module can communicate with circuit board 2 via the data bus.

[0045] Indicator light 31 can be an LED bulb, and its pins can be soldered onto circuit board 2.

[0046] For example, indicator light 31 may emit white light or other monochromatic light, multicolor light, etc.

[0047] For example, a light-emitting module can be provided on the circuit board 2. The light-emitting module can receive the charging status signals of the control module and the Bluetooth module and control the indicator light to light up.

[0048] Here, the circuit board 2 can control multiple indicator lights 31 to light up sequentially along the first direction according to the charging status of the device to be charged. On the one hand, the user can judge the real-time power of the device to be charged according to the number of indicator lights 31 lit up, so as to intuitively reflect the charging status. On the other hand, since they are lit sequentially along the first direction, compared with disordered lighting, the charging status can be reflected more intuitively, and the user experience is better.

[0049] For example, in one embodiment, the first direction may be the left-right direction of the vehicle.

[0050] In one embodiment, the indicator light 31 has a flashing state and a constant state after it is lit. The circuit board 2 controls the number of flashing and / or constant state of the multiple indicator lights 31 to indicate that the device to be charged has different levels of power.

[0051] Here, the number of flashing and / or constant-on indicator lights 31 controlled by circuit board 2 can be combined into multiple ways to provide more power information. This reduces the number of indicator lights 31 and power consumption, lowers costs, and enhances the display effect when using the flashing method, making it more intuitive.

[0052] For example, in one embodiment, the flashing effect can be a breathing flash, which maintains visibility of the status while avoiding glare from strong light.

[0053] In one embodiment, there are four indicator lights 31. The four indicator lights 31 are divided into a first indicator light, a second indicator light, a third indicator light, and a fourth indicator light along a first direction. When the power of the charging device is between 1% and 24%, the first indicator light flashes. When the power of the device to be charged is between 25% and 49%, the first and second indicator lights flash. When the power of the device to be charged is between 50% and 74%, the first, second, and third indicator lights flash. When the power of the device to be charged is between 75% and 99%, all four indicator lights 31 flash. When the power of the device to be charged is 100%, all four indicator lights 31 remain constantly lit.

[0054] Here, when only the first indicator light flashes, it means the current battery level of the device to be charged is between 1% and 24%; when only the first and second indicator lights flash simultaneously, it means the current battery level is between 25% and 49%; when only the first, second, and third indicator lights flash simultaneously, it means the current battery level is between 50% and 74%; when the first, second, third, and fourth indicator lights flash simultaneously, it means the current battery level is between 75% and 99%; and when the first, second, third, and fourth indicator lights are constantly lit, it means the current battery level is 100%. This provides a relatively clear visual representation of the battery level of the device to be charged.

[0055] As an example, in one embodiment, please refer to Figure 1 and Figure 3 When the charging module 1 is a wireless charging module, the charging module 1 includes a wireless charging coil 11, a wire harness 12 and a conductive cover 13. The wireless charging coil 11 can be connected to the circuit board 2 through the wire harness 12. The wireless charging coil 11 can be placed inside the conductive cover 13. In this way, not only can the wireless charging coil 11 be protected to a certain extent, but the alternating magnetic field generated by the wireless charging coil 11 during operation can also be effectively limited to spread outward, so as to reduce electromagnetic interference to other electronic devices.

[0056] In one embodiment, please refer to Figures 1 to 3 The charging device 100 includes a housing 4 and a cover 5. The housing 4 has a receiving cavity 4b and a mounting port 4a communicating with the receiving cavity 4b. The charging module 1 and the display module 3 are both disposed in the receiving cavity 4b. The cover 5 covers the mounting port 4a, and a light-transmitting mask 5a is provided on the surface of the cover 5.

[0057] Here, by providing a light-transmitting mask 5a on the cover 5, after the charging module 1 and the display module 3 are installed into the receiving cavity 4b through the mounting port 4a, the light of the display module 3 can be transmitted through the mask 5a to the outside of the cover 5. In this way, while the light can remind the user or allow the user to view it, the cooperation between the cover 5 and the housing 4 can protect the charging module 1 and the display module 3 to a certain extent and improve their service life.

[0058] In one embodiment, please refer to Figures 1 to 3 The cover 5 has a recessed placement groove 5b that faces the housing 4, and the placement groove 5b is used to place the device to be charged.

[0059] In this way, when the device to be charged is placed in the placement slot 5b for charging, the slot wall of the placement slot 5b can block the device to be charged to a certain extent, reducing the possibility of it sliding out of the placement slot 5b.

[0060] In one embodiment, please refer to Figure 3 The bottom wall of the placement slot 5b is inclined.

[0061] In this way, the tilt setting can guide the device to be charged to naturally adhere to the bottom of the tank by gravity, reducing the possibility of misalignment with the charging module 1 due to shaking.

[0062] In one embodiment, please refer to Figure 1 and Figure 3 The charging device 100 includes an anti-slip pad 10 disposed in the placement slot 5b. This provides some anti-slip protection for the device to be charged, reducing the possibility of misalignment with the charging module 1 that could prevent charging.

[0063] In one embodiment, please refer to Figure 1 The charging device 100 includes a PIN pin 6, which can be inserted between the circuit board 2 and the external circuit for transmitting electrical signals and conducting electricity.

[0064] In one embodiment, the mask 5a is made of polycarbonate (PC).

[0065] In this way, using polycarbonate as the material for the face mask 5a can not only improve the light transmittance of the face mask 5a, but also give the face mask 5a stable chemical properties, so that it is not easy to yellow or fog up during long-term use.

[0066] In one embodiment, the material of the mask 5a is emulsified PC. This can further improve the light transmittance of the mask 5a.

[0067] In one embodiment, the face mask 5a and the cover 5 are connected by two-color injection molding.

[0068] Here, the two-color injection molding is used to connect the face mask 5a and the cover 5, which can not only reduce the assembly gap between the two and prevent moisture, dust and other substances from entering the receiving cavity 4b, but also improve the connection stability between the two.

[0069] In one embodiment, the housing 4 and the cover 5 are detachably connected.

[0070] Here, the housing 4 and the cover 5 are connected by disassembly, which facilitates the inspection and maintenance of the components of the receiving cavity 4b.

[0071] For example, a detachable method could be a screw connection, such as housing 4 having a first mounting hole and cover 5 having a second mounting hole, and then connecting housing 4 and cover 5 by screws or bolts passing through the first mounting hole and the second mounting hole.

[0072] In one embodiment, please refer to Figure 1 and Figure 2 One of the housing 4 and the cover 5 has a snap fastener 5c, and the other of the housing 4 and the cover 5 has a slot 4c, and the snap fastener 5c engages with the slot 4c.

[0073] For example, the cover 5 may be formed with a buckle 5c, and the housing 4 may be formed with a slot 4c, with the buckle 5c engaging with the slot 4c.

[0074] In this way, by using the combination of buckle 5c and slot 4c, on the one hand, buckle 5c and slot 4c can be fastened together without the need for additional tools, resulting in high assembly efficiency; on the other hand, it can reduce the use of fasteners and reduce manufacturing costs.

[0075] For example, there can be multiple positions for the buckle 5c and the slot 4c. For instance, the cover 5 can have two buckles 5c along the first direction, and the housing 4 can have two slots 4c along the first direction. Each buckle 5c engages with the corresponding slot 4c to improve the connection strength between the two.

[0076] In one embodiment, please refer to Figure 1 and Figure 3 The charging device 100 includes a diffuser 7, which is located in the receiving cavity 4b and disposed between the indicator light 31 and the face mask 5a.

[0077] For example, the diffuser 7 can be a diffusion membrane.

[0078] Here, by setting a diffuser 7 between the indicator light 31 and the mask 5a, the light emitted by the indicator light 31 can be refracted, reflected and scattered multiple times to emit a more uniform light source, reducing the visual glare caused by local brightness concentration.

[0079] In one embodiment, the diffuser 7 and the mask 5a are connected by optical adhesive.

[0080] In this way, by using optical adhesive to connect the diffuser 7 and the mask 5a, the gap between the mask 5a and the diffuser 7 can be reduced, which in turn reduces the reflection and refraction of light in the air layer between the mask 5a and the diffuser 7, making the diffuser 7 transmit light more evenly and enhancing the light transmission display effect of the mask 5a.

[0081] In one embodiment, please refer to Figure 1 and Figure 3 The charging device 100 includes a light guide 8, which is located in the receiving cavity 4b and disposed between the indicator light 31 and the diffuser 7.

[0082] In other words, the light emitted by the indicator light 31 passes through the light guide 8, then through the diffuser 7, and finally shines through the mask 5a out of the cover 5.

[0083] For example, the light guide 8 can be a light guide post or a light guide tube.

[0084] In this way, by setting a light guide 8 between the indicator light 31 and the diffuser 7, on the one hand, the point light source of the indicator light 31 is converted into a uniform line light source or surface light source through the refraction and reflection structure in the light guide 8, so as to reduce the phenomenon of bright center and dark edge, and provide a more uniform light foundation for the subsequent diffuser 7; on the other hand, the light guide 8 can effectively control the light path, reduce the light scattering during the transmission process, and improve the overall light efficiency.

[0085] Another aspect of this application provides a vehicle that includes the charging device 100 from any of the above embodiments.

[0086] For example, the vehicle can be a gasoline vehicle, a hybrid vehicle, a range-extended vehicle, or a pure electric vehicle, etc.

[0087] The vehicle provided in this application, based on the advantages of the charging device 100, features accurate charging status feedback and a good user experience.

[0088] For example, in one embodiment, the charging device 100 is disposed in one or more of the front passenger dashboard, the front dashboard, the rear passenger dashboard, the rear seat, the front door armrest, and the rear door armrest. For example, the housing 4 is formed with a connection hole 4d, which can be installed by passing a self-tapping screw 9 through the connection hole 4d.

[0089] In one embodiment, the control module is a vehicle body controller.

[0090] The body control unit, also known as the body computer, is an electronic control unit used to control the electrical systems of a vehicle body.

[0091] For example, circuit board 2 is communicatively connected to the body controller. The body controller can be integrated on the circuit board in the form of power management chips, MCUs, and other components. The control module can monitor the charging status of the device to be charged in real time through control circuits such as sensors and microcontroller units, and work with the charging module to realize power transmission, thereby obtaining the output power of the module to be charged.

[0092] Here, the vehicle's body controller is used as a control module to obtain the output power of the charging module 1, eliminating the need for additional electronic components and reducing manufacturing costs.

[0093] For example, in one embodiment, the device to be charged is placed in the placement slot 5b. The induced magnetic field of the wireless charging coil 11 in the charging device changes and generates current. The output power of the charging module 1 is obtained through the vehicle body controller and the power of the device to be charged is obtained through the Bluetooth module. The charging status information is sent to the circuit board 2. The circuit board 2 controls the indicator lights 31 to light up based on the charging status information. If the output power is low and multiple indicator lights 31 are constantly lit, it indicates that the charging is complete and the device to be charged is fully charged. If the output power is high and the indicator lights 31 are flashing, it indicates that the charging is not complete and the device to be charged is charging.

[0094] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
