Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an on-board power supply device and a vehicle. Background Technology

[0002] Currently, vehicles have a limited number of power supply interfaces, most of which are concentrated in the front of the cabin, such as the center console and dashboard. These interfaces cover the front half of the vehicle, allowing the vehicle to meet the power needs of passengers in the front and related electronic devices located there. However, due to insufficient power supply interfaces in the rear half of the vehicle, the vehicle cannot meet the power needs of passengers in the rear or related electronic devices. This is particularly problematic for situations where electronic devices (such as trunk lights, car cameras, and in-vehicle projectors) need to be installed in the trunk. Existing power supply solutions are insufficient to address this issue. Forcing power from the front cabin interfaces to the rear cabin's electronic devices would result in excessively long cables, complex wiring, and unstable power supply. Utility Model Content

[0034] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] With the development of technology and the increasing number of in-vehicle electronic devices, the power supply interfaces in vehicles are gradually becoming insufficient to meet the needs of passengers or electronic devices. For example, when there are many passengers, the power supply interfaces are often insufficient, and when there are many in-vehicle electronic devices, the power supply interfaces are also often insufficient.

[0037] Currently, vehicles have a limited number of power outlets, most of which are concentrated in the front of the vehicle cabin, such as the center console and dashboard. These power outlets cover the front half of the vehicle, allowing the vehicle to meet the power needs of passengers in the front half or the power needs of related electronic devices located in the front half. Here, "passengers" refers to those sitting in the front seats, including the driver. "Electronic devices" refers to those located in the front seats, such as in-car electronic air fresheners and charging adapters.

[0038] However, for the rear section of the vehicle, due to insufficient power supply interfaces, the vehicle cannot meet the power needs of passengers and related electronic devices located in the rear section. These passengers refer to those sitting in the rear or middle rows. The electronic devices include, for example, those installed in the trunk ceiling, such as trunk lighting, gimbal cameras, and in-vehicle projectors. Furthermore, providing power to these rear-section electronic devices presents challenges such as complex wiring and unstable power supply.

[0039] Based on the above problems and current situation, this application provides an on-board power supply device that can be installed in the rear half of the vehicle (the rear of the vehicle cabin). For example, the on-board power supply device can be installed in the trunk roof. The on-board power supply device can meet the power supply needs of passengers located in the rear half of the vehicle and the power needs of related electronic devices located in the rear half of the vehicle.

[0040] In the embodiments of this application, it should be understood that power supply demand refers to the passenger's need for electrical energy, including the passenger's use of related electronic devices, which are usually mobile devices such as mobile phones. Power demand refers to the electrical connection between the electronic device and the vehicle, such as the aforementioned in-vehicle electronic air freshener, which needs to be connected to the circuit in the vehicle.

[0041] Based on the above-mentioned vehicle power supply device, this application embodiment also provides a vehicle that includes the above-mentioned vehicle power supply device, which can meet the power supply needs of passengers and the power needs of related electronic devices.

[0042] Figure 1 A schematic diagram of the structure of an on-board power supply device according to an embodiment of this application is shown; Figure 2 An exploded view of an on-board power supply device provided according to an embodiment of this application is shown.

[0043] In the embodiments of this application, please refer to Figure 1 and Figure 2The vehicle power supply device includes a front power connector (not shown in the figure) located at the front of the vehicle cabin. This front power connector is located at the front of the vehicle cabin, so that the vehicle can meet the power supply needs of passengers located in the front half or meet the power supply needs of related electronic devices located in the front half.

[0044] The vehicle-mounted power supply unit also includes a base 100 and a rear power supply connector 200.

[0045] The base 100 is a structure in the vehicle power supply device that needs to be connected to the vehicle. The base 100 can be fixedly connected to an appropriate position in the vehicle. The base 100 can be connected to the rear of the vehicle cabin, for example, the base 100 can be connected to the trunk roof. Specifically, the base 100 can be connected to the sheet metal of the vehicle corresponding to the roof position by fasteners such as screws, so that the base 100 can make full use of the vehicle space and not affect the passenger's activity space.

[0046] It should be noted that the terms "front" and "rear" are defined based on the length of the vehicle. In other words, for a vehicle, the side pointing towards the front of the vehicle along its length is the front, and the side pointing towards the rear of the vehicle is the rear.

[0047] The base 100 can be connected to the vehicle as a standard structure, maintaining a connection. When power is needed, the rear power connector 200 is simply attached to the base 100. Essentially, the base 100 can be installed as a pre-installed component at the vehicle's factory. The rear power connector 200 can be detachably connected to the base 100 as described in the following embodiments. It should be noted that, to prevent accidental electric shock when power is not required, an insulating shell can be fitted onto the base 100.

[0048] Of course, the base 100 and the rear power connector 200 can also be combined in other ways. For example, the rear power connector 200 and the base 100 can both be installed on the vehicle when it leaves the factory.

[0049] It should be understood that, in some embodiments, the base 100 and / or the rear power connector 200 are assembled into a vehicle power supply device using a detachable connection method, which not only meets the user's needs but also does not occupy the vehicle's interior space.

[0050] In this embodiment, the base 100 is connected to the vehicle and forms a connection with the vehicle's power supply circuit. For example, the base 100 can be connected to a power supply unit in the vehicle, such as a battery. Alternatively, the rear power connector 200 can also be designed to connect to the power supply circuit.

[0051] It should be noted that, to adapt to electronic devices with different rated voltages, the base 100 can integrate a voltage conversion module, which can be selected according to requirements. Thus, the base 100 can convert the vehicle's voltage into a voltage compatible with various electronic devices; for example, it can convert the vehicle's 12V battery to 5-20V.

[0052] As can be seen from the following embodiments, a second conductive spring pin 500 is provided on the base 100. The second conductive spring pin 500 is an electrical contact on the base 100, and the rear power supply connector 200 can be connected to the electrical contact to form an electrical connection.

[0053] In this embodiment, the rear power connector 200 is electrically connected to the base 100, and the rear power connector 200 is connected to the power supply circuit in the vehicle.

[0054] The power supply circuit can transmit current to the rear power supply connector 200, which can then become the output terminal of the current.

[0055] It should be noted that the power supply connector 200 can be configured, and the number and type of power supply interfaces can be set according to requirements. The specific structure of the power supply interface can be referred to relevant technologies.

[0056] In this embodiment, the vehicle power supply device includes a front power connector located at the front of the vehicle cabin, enabling the vehicle to meet the power supply needs of passengers in the front section or the power needs of related electronic devices located in the front section. Additionally, the device includes a base 100 and a rear power connector 200, to which current from the power supply circuit can be delivered, allowing the rear power connector 200 to charge electronic devices. During installation, the base 100 and rear power connector 200 can be installed in the rear section of the vehicle, for example, on the top of the rear seats or in the trunk roof, thereby filling the gap in power supply interfaces in the rear section. This vehicle power supply device can meet the power supply needs of passengers in the rear section of the vehicle and the power needs of related electronic devices located in the rear section. Furthermore, because power is supplied or drawn directly from the rear of the vehicle cabin, problems such as excessively long cables, complex wiring, and unstable power supply are avoided.

[0057] In some embodiments, the rear power connector 200 may include multiple power interfaces, including at least a USB interface and a Type-C interface, so that the power interfaces can be adapted to various different electronic devices.

[0058] In some embodiments, please refer to Figure 1The base 100 is provided with a plurality of mounting positions 101, each mounting position 101 being used to mount at least one rear power connector 200.

[0059] Therefore, the size of the base 100 can be reasonably designed according to the interior space of the vehicle. For example, when there is ample space in the vehicle, the base 100 can be designed to be larger, so that multiple rear power connectors 200 can be installed on the same base 100 (see reference). Figure 1 Multiple rear power connectors 200 can be installed on the base 100. Figure 1 (Only one rear power connector 200 is shown in the image), thereby increasing the number of power supply interfaces in the vehicle. For example, when the space in the vehicle is small, the base 100 can be designed to be smaller, and one rear power connector 200 can be installed on one base 100. In short, by reasonably configuring the size of the base 100, the number of power supply interfaces can be increased or decreased, and the vehicle power supply device can be matched with the space in the vehicle.

[0060] In some embodiments, please refer to Figure 1 and Figure 2 The power supply connector 200 is detachably connected to the base 100.

[0061] As mentioned above, since the rear power connector 200 is detachably connected to the base 100, the installation of the rear power connector 200 can be eliminated when no additional power supply interface is needed, thereby avoiding the rear power connector 200 occupying the interior space of the vehicle.

[0062] In this embodiment of the application, in order to achieve a detachable connection of the rear power connector 200, the rear power connector 200 and the base 100 can be provided with a male and female plug or a snap-fit ​​structure. In addition, the rear power connector 200 can also be connected to the base 100 by magnetic adsorption.

[0063] In this embodiment of the application, in order to improve the connection reliability between the rear power supply connector 200 and the base 100, and also to facilitate the installation and removal of the rear power supply connector 200, this embodiment of the application also provides a method of rotational snap-fit ​​to achieve a detachable connection between the rear power supply connector 200 and the base 100. The rotational snap-fit ​​method can be referred to in the following embodiments.

[0064] In some embodiments, please refer to Figure 1 and Figure 2 The base 100 is provided with a receiving cavity 102, and the rear power connector 200 is provided with a plug-in structure 210, which is used to be inserted into the receiving cavity 102 and fixed to the base 100.

[0065] The use of a plug-in structure 210 to mate with the receiving cavity 102 simplifies the connection between the rear power connector 200 and the base 100. During assembly, simply insert the rear power connector 200 into the receiving cavity 102. It is understood that the aforementioned plug-in male and female connectors, snap-fit ​​structures, and magnetic adsorption methods can be integrated into the plug-in structure 210 and the receiving cavity 102. For example, at least a portion of the material of the plug-in structure 210 may be magnetic, and at least a portion of the material inside the receiving cavity 102 may be magnetic.

[0066] Figure 3 It shows Figure 2 A schematic diagram of the base 100 without the plug-in housing 213; Figure 4 A schematic diagram of the structure of a connector 211 and a receiving cavity 102 according to an embodiment of this application is shown; Figure 5 A partially enlarged view of a base 100 provided according to an embodiment of this application is shown.

[0067] In some embodiments, please refer to Figures 3 to 5 The plug-in structure 210 includes a rotatably configured plug-in member 211, which includes a locking end 2111. The base 100 has a slot 103 communicating with the receiving cavity 102. The locking end 2111 has a locking position that engages with the slot 103 and an unlocking position that disengages from the slot 103.

[0068] It is understandable that the connector 211 has at least a locking position and an unlocking position during its rotational stroke. When the connector 211 is in the locking position, the locking end 2111 cooperates with the slot 103 to lock the connector 211, so that the rear power connector 200 is fixedly connected to the base 100. When the connector 211 is in the unlocking position, the locking end 2111 disengages from the slot 103 and is unlocked, so that the rear power connector 200 can be removed from the base 100.

[0069] Therefore, when it is necessary to install the rear power supply connector 200 onto the base 100 or remove the rear power supply connector 200 from the base 100, it is only necessary to rotate the plug 211 and switch it between the locked and unlocked positions, which is a simple operation.

[0070] In some specific embodiments, please refer to Figure 4 The connector 211 includes a rotating part 2112. The locking end 2111 can be located on the outside of the rotating part 2112 and extend outward from the rotating part 2112. The specific structure of the rotating part 2112 is not limited; the rotating part 2112 can be circular or elliptical, etc., and the locking end 2111 can be a protrusion, etc. For example, in Figure 4In the example shown, the rotating part 2112 has a rectangular structure, and the locking end 2111 is a protrusion.

[0071] Furthermore, to improve connection reliability, the connector 211 may include multiple locking ends 2111, and the base 100 may be fitted with multiple slots 103, for example, please refer to Figure 4 The connector 211 may include two locking ends 2111. Correspondingly, the base 100 may have two slots 103. The cooperation between the two locking ends 2111 and the two slots 103 can improve the stability of the locking ends 2111 in the locked position and prevent the rear power connector 200 from detaching from the base 100 when the vehicle vibrates.

[0072] It can be seen that when the plug-in 211 is rotated, the detachable connection between the rear power connector 200 and the base 100 can be achieved by the locking end 2111 and the slot 103. This detachable connection method is the rotary locking mentioned above.

[0073] In some embodiments, please refer to Figure 3 and Figure 5 The base 100 is also provided with an elastic abutment 300, which abuts against the plug 211 when the locking end 2111 is in the locking position.

[0074] The elastic abutment 300 can be made of an elastic material, such as a spring. By setting the elastic abutment 300, when the locking end 2111 is in the locked position, the elastic abutment 300 and the plug 211 can form an abutment force, thereby making the plug 211 stably engaged in the slot 103.

[0075] Specifically, when the locking end 2111 is in the unlocked position, there is no interaction between the plug 211 and the elastic abutment 300. As the plug 211 is rotated and switched from the unlocked position to the locked position, the plug 211 gradually approaches the elastic abutment 300 and causes the elastic abutment 300 to deform, thereby creating an interaction force between the elastic abutment 300 and the plug 211, thus keeping the plug 211 in the locked position.

[0076] It is understood that the elastic abutment 300 can be positioned where the rotating part 2112 cannot contact it but the locking end 2111 can contact it, so that the aforementioned interaction force can be formed between the locking end 2111 and the elastic abutment 300.

[0077] In some specific embodiments, please refer to Figure 5The elastic abutment 300 includes an upright portion 310 and an inclined portion 320. The upright portion 310 is connected to the base 100, and the inclined portion 320 is connected to the upright portion 310 and is inclined toward the slot 103. The inclined portion 320 is used to abut the plug 211.

[0078] The above-mentioned upright part 310 and inclined part 320 can improve the structural strength of the elastic abutment 300 and extend the service life of the elastic abutment 300, while not interfering with the rotation of the plug 211.

[0079] Specifically, due to the inclined portion 320, a structure can be formed between the inclined portion 320 and the slot 103, where the outer end 104 has a larger diameter and the inner end 105 has a smaller diameter. When the connector 211 rotates, the connector 211 can gradually approach the inclined portion 320 from the outer end 104. The inclined portion 320 will not interfere with the connector 211 entering the outer end 104, allowing the connector 211 to enter the inner end 105, thereby causing the connector 211 to be abutted by the inclined portion 320. When the inclined portion 320 and the connector 211 abut against each other, the force between them can be transmitted to the upright portion 310. The force can be transmitted along the axial direction of the upright portion 310, preventing excessive bending of the elastic abutment portion as a whole, thereby improving the service life of the elastic abutment portion.

[0080] In conjunction with the foregoing, the inclined portion 320 can be located in the slot 103, so that the inclined portion 320 can abut against the locking end 2111 of the connector 211.

[0081] In some embodiments, please refer to Figures 1 to 3 The plug-in structure 210 also includes a drive assembly 212, to which the plug 211 is connected, and the drive assembly 212 is used to drive the plug 211 to rotate.

[0082] The drive component 212 can be a component capable of outputting power. For example, the drive component 212 can be a combination of a motor and a gear. The motor can drive the gear to rotate, and the connector 211 is on the gear, thereby enabling the automatic rotation of the connector 211.

[0083] The drive component 212 can also be operated manually, and the rotation of the connector 211 can also be achieved by manually operating the drive component 212.

[0084] In some embodiments, please refer to Figure 3 The drive assembly 212 includes a drive handle 2121 and a connector 2122. The connector 2122 is connected between the drive handle 2121 and the plug 211. The drive handle 2121 has a control end 2121a.

[0085] As mentioned above, since the plug-in structure 210 needs to be inserted into the receiving cavity 102, the connector 2122 can be a connecting rod, the length of which can be designed according to the depth of the receiving cavity 102. The drive handle 2121 and the connector 2122, as well as the connector 2122 and the plug-in 211, can be connected by mechanical connection or by welding.

[0086] Therefore, by rotating the drive handle 2121, the connector 211 can be driven to rotate, thereby switching the connector 211 between the locked and unlocked positions.

[0087] In some embodiments, please refer to Figure 3 The drive handle 2121 may include a rotating platform 2121b and the aforementioned control end 2121a. The rotating platform 2121b may be designed as a circular structure, and the connector 2122 is connected to the middle position of the rotating platform 2121b. The control end 2121a may be a lug extending from a certain part of the rotating platform 2121b.

[0088] In some embodiments, please refer to Figure 3 To facilitate the replacement and maintenance of the connector 211, the connector 211 is detachably mounted on the connector 2122. At this time, the connector 2122 may have an external thread at its end, and the connector 211 can be connected to the connector 2122 by threaded connection. To prevent the connector 211 from detaching from the connector 2122, a locking nut 2123 or other structure may be provided at the end of the connector 2122.

[0089] In some embodiments, reference Figures 1 to 3 The plug-in structure 210 also includes a plug-in housing 213, a drive handle 2121 and a connector 2122 which can be housed in the plug-in housing 213. An opening 2131 is provided on one side of the plug-in housing 213, and the control end 2121a extends out from the opening 2131. The connector 211 is provided on the outside of the plug-in housing 213.

[0090] The plug-in housing 213 protects the drive handle 2121 and the connector 2122, and the control end 2121a extends from the opening 2131 for easy operation by the user. The connector 211 is disposed in the housing of the plug-in housing 213 to facilitate engagement with the slot 103 on the base 100.

[0091] To ensure smooth and stable rotation of the drive handle 2121, please refer to... Figure 2The plug-in housing 213 is provided with a receiving platform 2132 corresponding to the opening 2131. The receiving platform 2132 can drive the rotating platform 2121b of the handle 2121 to correspond to it. On the one hand, the control end 2121a of the drive handle 2121 can extend from the opening 2131. On the other hand, the rotating platform 2121b and the bearing platform have a large contact area, and the two can rotate smoothly and stably.

[0092] In some embodiments, please refer to Figure 2 The plug-in housing 213 includes a first boss 2133 and a second boss 2134. The second boss 2134 protrudes from the first boss 2133 and is recessed within the first boss 2133, with at least a gap between the edge of the second boss 2134 and the edge of the first boss 2133. The plug-in member 211 is disposed on the outside of the second boss 2134.

[0093] The design of the plug-in housing 213, including the first boss 2133 and the second boss 2134, allows the gap between the edge of the first boss 2133 and the edge of the second boss 2134 to serve as a positioning feature when the rear power connector 200 is installed on the base 100. Specifically, the second boss 2134 can be inserted into and received in the receiving cavity 102, while the first boss 2133 can be positioned at the periphery of the receiving cavity 102, which can prevent the plug-in structure 210 from being inserted incompletely or excessively.

[0094] In some embodiments, please refer to Figure 2 The plug-in structure 210 also includes a connector 214, which is connected to the plug-in structure 210 and can be provided with multiple power supply interfaces.

[0095] Figure 6 A cross-sectional view of an on-board power supply device provided according to an embodiment of this application is shown.

[0096] Based on the preceding text and with reference to Figure 1 , Figure 2 , Figure 3 and Figure 6 In some embodiments, a first conductive spring pin 400 is provided on the second protrusion 2134, and a second conductive spring pin 500 electrically connected to the second conductive spring pin 500 is provided on the base 100.

[0097] Therefore, after the rear power connector 200 is installed on the base 100, electrical conduction between the rear power connector 200 and the base 100 can be achieved through the connection between the first conductive spring pin 400 and the second conductive spring pin 500. It should be understood that the first conductive spring pin 400 can be positioned to avoid the connector 211. For example, the first conductive spring pin 400 can be located on the outside of the connector 211. Correspondingly, the second conductive spring pin 500 can be located at the edge of the receiving cavity 102.
