[0014] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0015] Please refer to Figure 1-Figure 3 As shown, this application proposes an on-board charging device 1, which has multiple functions and is convenient for users to use.

[0016] The on-board charging device 1 is suitable for charging electronic devices (not shown in the figure). The on-board charging device 1 includes a base 10, a connecting structure 20, and a charging module 30. The base 10 has a first receiving slot 10a and a second receiving slot 10b, which are independent of each other. The first receiving slot 10a is used to place external components. The connecting structure 20 is at least partially disposed within the second receiving slot 10b. The charging module 30 is configured to charge electronic devices. The charging module 30 is at least partially embedded within the second receiving slot 10b and is positioned on the base 10 via the connecting structure 20.

[0017] The following combination Figure 1-Figure 5 The specific structure of the vehicle charging device 1 will be described in detail below. It should be noted that the vehicle charging device 1 in this embodiment can be used, but is not limited to, charging electronic devices such as mobile phones, headphones, and tablets.

[0018] like Figure 1-Figure 3 As shown, the on-board charging device 1 includes a base 10, a connecting structure 20, and a charging module 30.

[0019] The base 10 serves as the base of the vehicle charging device 1. The specific shape of the base 10 is not limited here. Designers can make reasonable designs according to actual needs. For example, the shape of the base 10 can be, but is not limited to, a rectangle, a circle, or a regular hexagon, etc.

[0020] The base 10 has a first receiving groove 10a and a second receiving groove 10b that are independent of each other. The first receiving groove 10a is used to place external parts, wherein the external parts may be, but are not limited to, objects such as keys, lighters or nail clippers.

[0021] The connection structure 20 serves as an intermediate connector between the charging module 30 and the base 10; the specific form of the connection structure 20 will be described in detail below.

[0022] The connecting structure 20 is at least partially disposed within the second receiving groove 10b. For example, the connecting structure 20 may be entirely disposed within the second receiving groove 10b; or, for another example, the connecting structure 20 may be partially disposed within the second receiving groove 10b, with the remaining portion disposed outside the second receiving groove 10b.

[0023] The charging module 30 serves as the charging structure of the on-board charging device 1, and is configured to charge electronic devices. The specific structure of the charging module 30 is not limited here; designers can design it appropriately according to actual needs. In this embodiment, the charging module 30 uses wireless charging to charge the electronic devices.

[0024] The charging module 30 is at least partially embedded in the second receiving groove 10b. For example, the charging module 30 may be entirely embedded in the second receiving groove 10b; or, for another example, the charging module 30 may be partially embedded in the second receiving groove 10b, with the remaining portion extending out of the second receiving groove 10b through the opening of the second receiving groove 10b.

[0025] The charging module 30 is positioned on the base 10 via the connecting structure 20. The specific connection method between the connecting structure 20 and the charging module 30 is not limited here; designers can design it appropriately according to actual needs. For example, the connecting structure 20 can be detachably connected to the charging module 30 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the connecting structure 20 can be non-detachably connected to the charging module 30 by adhesive bonding or riveting. The specific connection method between the connecting structure 20 and the base 10 is not limited here; designers can design it appropriately according to actual needs. For example, the connecting structure 20 can be detachably connected to the base 10 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the connecting structure 20 can be non-detachably connected to the base 10 by adhesive bonding or riveting.

[0026] Based on the vehicle charging device 1 in this application embodiment, the base 10 is divided into a first receiving slot 10a and a second receiving slot 10b, which are independent of each other. The first receiving slot 10a can be used to place external parts such as keys, lighters or nail clippers for users to put in and take out. The second receiving slot 10b is used to accommodate the charging module 30. Users can place electronic devices on the charging module 30 so that the charging module 30 can charge the electronic devices. Compared with the vehicle charging device 1 in the related technology, which can only charge electronic devices, the vehicle charging device 1 in this application embodiment can both charge electronic devices and store external parts, which is multifunctional and convenient for users.

[0027] It is worth mentioning that the base 10 is divided into two independent receiving slots: a first receiving slot 10a and a second receiving slot 10b. The first receiving slot 10a provides sufficient space for external components, resulting in a larger overall volume of the base 10. This enhances the stability of the vehicle charging device 1 when placed on the vehicle's dashboard, reducing the likelihood of it tipping over and thus improving stability during charging. Furthermore, with external components placed in the first receiving slot 10a, the base 10 is more stably positioned on the vehicle's dashboard under the weight of the external components (lowering the overall center of gravity of the vehicle charging device 1), further enhancing stability during charging.

[0028] like Figure 1-Figure 2As shown, the first receiving groove 10a is arranged around the second receiving groove 10b. This provides sufficient accommodating space for external components, facilitating the user's placement and removal of external components.

[0029] like Figure 3-Figure 5 As shown, the bottom of the charging module 30 is provided with a first fixing hole 30a, and the bottom wall of the second receiving groove 10b is provided with a first through hole 10c. The connection structure 20 includes a connecting seat 21, a first fastener 22, and a second fastener (not shown in the figure); the connecting seat 21 is at least partially located in the second receiving groove 10b, and the connecting seat 21 has a second through hole 21a corresponding to the first fixing hole 30a, and a second fixing hole 21b corresponding to the first through hole 10c; the first fastener 22 passes through the second through hole 21a and the first fixing hole 30a to position the connecting seat 21 on the charging module 30; the second fastener passes through the first through hole 10c and is connected to the second fixing hole 21b to position the connecting seat 21 on the base 10.

[0030] The first fixing hole 30a is a hole on the charging module 30 that cooperates with the first fastener 22 to fix the relative position between the connector 21 and the charging module 30; the first fastener 22 is a component that cooperates with the first fixing hole 30a to fix the relative position between the connector 21 and the charging module 30. Depending on the specific form of the first fixing hole 30a, the specific form of the first fastener 22 that cooperates with it also varies. For example, when the first fixing hole 30a is a threaded hole formed at the bottom of the charging module 30, the first fastener 22 includes a screw, and the connecting seat 21 and the charging module 30 are relatively fixed in position by locking the screw. As another example, when the first fixing hole 30a is a snap hole formed at the bottom of the charging module 30, the first fastener 22 includes a snap pin, and the connecting seat 21 and the charging module 30 are relatively fixed in position by snapping the snap pin. As yet another example, when the first fixing hole 30a is a plug hole formed at the bottom of the charging module 30, the first fastener 22 includes a pin, and the connecting seat 21 and the charging module 30 are relatively fixed in position by inserting the pin.

[0031] The second fixing hole 21b is a hole on the connecting seat 21 used to cooperate with the second fastener to fix the relative position between the connecting seat 21 and the base 10; the second fastener is a component that cooperates with the second fixing hole 21b to fix the relative position between the connecting seat 21 and the base 10. Depending on the specific form of the second fixing hole 21b, the specific form of the cooperating second fastener also varies; for example, when the second fixing hole 21b is a threaded hole formed on the connecting seat 21, the second fastener includes a screw, and the connecting seat 21 and the base 10 are fixed in position by locking the screw; as another example, when the second fixing hole 21b is a snap-fit ​​hole formed on the connecting seat 21, the second fastener includes a snap-fit ​​pin, and the connecting seat 21 and the base 10 are fixed in position by snap-fitting the snap-fit ​​pin; as yet another example, when the second fixing hole 21b is an insertion hole formed on the connecting seat 21, the second fastener includes a pin, and the connecting seat 21 and the base 10 are fixed in position by inserting the pin.

[0032] By designing a first fastener 22, which passes through a second through hole 21a and a first fixing hole 30a, the connector 21 is positioned on the charging module 30, thereby achieving relative fixation between the connector 21 and the charging module 30. By designing a second fastener, which passes through a first through hole 10c and connects to the second fixing hole 21b, the connector 21 is positioned on the base 10, thereby achieving relative fixation between the connector 21 and the base 10. In this way, the relative fixation between the charging module 30 and the base 10 can be achieved.

[0033] Specifically, the first fixing hole 30a is a through hole, and one end of the second through hole 21a forms a countersunk hole (not shown in the figure). The first fastener 22 includes a fastening bolt 221 and a fastening screw 222; the fastening bolt 221 is embedded in the countersunk hole; the fastening screw 222 passes through the second through hole 21a and the first fixing hole 30a, and the fastening screw 222 is threadedly connected to the fastening bolt 221 to position the connector 21 on the charging module 30. By designing the fastening screw 222 and the fastening bolt 221, with the fastening screw 222 passing through the second through hole 21a and the first fixing hole 30a and threadedly connected to the fastening bolt 221, the relative position between the connector 21 and the charging module 30 can be fixed, resulting in a simple structure that is easy to implement.

[0034] like Figure 3-Figure 5As shown, the bottom surface of the base 10 has a groove 10d in the area corresponding to the second receiving groove 10b; the connecting structure 20 also includes a connecting piece 23, which has a third through hole 23a corresponding to the first through hole 10c. The connecting piece 23 is embedded in the groove 10d, and the second fastener passes through the third through hole 23a and the first through hole 10c in sequence and is connected to the second fixing hole 21b to position the connecting seat 21 on the base 10.

[0035] Specifically, when the second fixing hole 21b is a threaded hole, the second fastener includes a screw, which passes through the third through hole 23a and the first through hole 10c in sequence and is threadedly connected to the threaded hole to achieve relative fixation between the connecting seat 21 and the base 10; when the second fixing hole 21b is a locking hole, the second fastener includes a locking pin, which passes through the third through hole 23a and the first through hole 10c in sequence and is engaged with the locking hole to achieve relative fixation between the connecting seat 21 and the base 10; when the second fixing hole 21b is an insertion hole, the second fastener is a pin, which passes through the third through hole 23a and the first through hole 10c in sequence and is engaged with the insertion hole to achieve relative fixation between the connecting seat 21 and the base 10.

[0036] In this design, the second fastener passes through the third through hole 23a and the first through hole 10c in sequence and is connected to the second fixing hole 21b. The connecting seat 21 and the connecting piece 23 cooperate with each other to clamp and fix the base 10 from the upper and lower sides, which can further enhance the connection stability between the connecting structure 20 and the base 10.

[0037] like Figure 3-Figure 5 As shown, the bottom surface of the groove 10d is provided with a first mating part 11; the connecting piece 23 includes a piece body 231 and a first limiting part 232; the piece body 231 is embedded in the groove 10d and has a third through hole 23a; the first limiting part 232 is provided on the side of the piece body 231 facing the bottom surface of the groove 10d, and the first limiting part 232 is inserted and engaged with the first mating part 11 to restrict the connecting piece 23 from rotating relative to the base 10.

[0038] The first mating part 11 serves as a limiting structure, used to engage with the first limiting part 232 to restrict the rotation of the connecting piece 23 relative to the base 10. The specific connection method between the first mating part 11 and the base 10 is not limited here; designers can design it reasonably according to actual needs. For example, the first mating part 11 can be integrally formed with the base 10 by injection molding or 3D printing, but is not limited to this method.

[0039] The first limiting part 232 serves as a limiting structure, used to engage with the first mating part 11 to restrict the rotation of the connecting piece 23 relative to the base 10. The specific connection method between the first limiting part 232 and the piece 231 is not limited here; designers can design it reasonably according to actual needs. For example, the first limiting part 232 can be integrally formed with the piece 231 by injection molding or 3D printing, but is not limited to this method.

[0040] The first mating part 11 may be, but is not limited to, a virtual structure such as a limiting groove formed on the base 10, and the corresponding first limiting part 232 may be, but is not limited to, a physical structure such as a limiting protrusion provided on the side of the plate 231 facing the bottom surface of the groove 10d; of course, the first mating part 11 may also be, but is not limited to, a physical structure such as a limiting protrusion provided on the bottom surface of the groove 10d, and the corresponding first limiting part 232 may also be, but is not limited to, a virtual structure such as a limiting groove formed on the side of the plate 231 facing the bottom surface of the groove 10d.

[0041] By designing a first limiting part 232 and a first mating part 11, the first limiting part 232 and the first mating part 11 are interlocked, which can restrict the rotation of the connecting piece 23 relative to the base 10, so that the second fastener can lock and fix the connecting piece 23 onto the base 10. It is worth mentioning that during the assembly process of the connecting piece 23 and the base 10, by having the first limiting part 232 and the first mating part 11 interlock, the position between the connecting piece 23 and the base 10 can also be pre-positioned, thus reducing the assembly difficulty between the connecting piece 23 and the base 10.

[0042] like Figure 3-Figure 5 As shown, the bottom surface of the second receiving groove 10b is provided with a second mating part 12; the connecting seat 21 includes a seat body 211 and a second limiting part 212; the seat body 211 is located in the second receiving groove 10b and has a second through hole 21a and a second fixing hole 21b; the second limiting part 212 is provided on the side of the seat body 211 facing the bottom surface of the second receiving groove 10b, and the second limiting part 212 is inserted and engaged with the second mating part 12 to restrict the connecting seat 21 from rotating relative to the base 10.

[0043] The second mating part 12 serves as a limiting structure, used to engage with the second limiting part 212 to restrict the rotation of the connecting seat 21 relative to the base 10. The specific connection method between the second mating part 12 and the base 10 is not limited here; designers can design it reasonably according to actual needs. For example, the second mating part 12 can be integrally formed with the base 10 by injection molding or 3D printing, but is not limited to this method.

[0044] The second limiting part 212 serves as a limiting structure, used to engage with the second mating part 12 to restrict the rotation of the connecting seat 21 relative to the base 10. The specific connection method between the second limiting part 212 and the seat 211 is not limited here; designers can design it reasonably according to actual needs. For example, the second limiting part 212 can be integrally formed with the seat 211 by injection molding or 3D printing, but is not limited to this method.

[0045] The second mating part 12 may be, but is not limited to, a virtual structure such as a limiting groove formed on the base 10, and the corresponding second limiting part 212 may be, but is not limited to, a physical structure such as a limiting protrusion provided on the side of the base 211 facing the bottom surface of the second receiving groove 10b; of course, the second mating part 12 may also be, but is not limited to, a physical structure such as a limiting protrusion provided on the bottom surface of the second receiving groove 10b, and the corresponding second limiting part 212 may also be, but is not limited to, a virtual structure such as a limiting groove formed on the side of the base 211 facing the bottom surface of the second receiving groove 10b.

[0046] By designing a second limiting part 212 and a second mating part 12, the second limiting part 212 and the second mating part 12 are interlocked, which can restrict the rotation of the connecting seat 21 relative to the base 10, so that the second fastener can lock and fix the connecting seat 21 onto the base 10. It is worth mentioning that during the assembly process of the connecting seat 21 and the base 10, by having the second limiting part 212 and the second mating part 12 interlock, the position between the connecting seat 21 and the base 10 can also be pre-positioned, thus reducing the assembly difficulty between the connecting seat 21 and the base 10.

[0047] like Figure 1 As shown, the charging module 30 has a mating surface 30b for attaching to the back of the electronic device, and a number plate 40 is provided on the edge of the base 10 facing away from the mating surface 30b. By designing the number plate 40, the on-board charging device 1 also has an indication function, allowing users to display their contact information through the number plate 40 for easy contact by others.

[0048] Other structural designs for the base 10 may be, but are not limited to, one or more of the following embodiments.

[0049] like Figure 1As shown, in the first embodiment, the bottom surface of the first receiving groove 10a is provided with a friction structure 13. The friction structure 13 may be, but is not limited to, a plurality of semi-circular protrusions or a plurality of elongated protrusions disposed on the bottom surface of the first receiving groove 10a. By designing the friction structure 13 on the bottom surface of the first receiving groove 10a, when an external component is placed in the first receiving groove 10a, the frictional force between the external component and the bottom surface of the first receiving groove 10a is sufficiently large, effectively enhancing the stability of the external component placed in the first receiving groove 10a (e.g., when the vehicle brakes or accelerates, the external component will not roll freely within the first receiving groove 10a due to inertia and detach from the first receiving groove 10a).

[0050] like Figure 4 As shown, in the second embodiment, the bottom surface of the base 10 is provided with a hollow structure 14. The hollow structure 14 can be, but is not limited to, hollow holes or hollow grooves. By designing the hollow structure 14 on the bottom surface of the base 10, material can be saved.

[0051] In the third embodiment, the base 10 is made of one of the following materials: elastic rubber, elastic silicone, or elastic plastic. This makes the base 10 flexible and allows it to fit as closely as possible to the vehicle's dashboard, thereby improving the stability of the on-board charging device 1 when placed on the vehicle's dashboard.

[0052] like Figures 3-4 As shown, the on-board charging device 1 also includes a sealing film 50, which is disposed on the bottom surface of the base 10 and configured to position the base 10 on the vehicle's dashboard. The side of the sealing film 50 facing away from the bottom surface of the base 10 is coated with an adhesive such as a glue layer. In this design, by designing the sealing film 50, the base 10 can be fixed to the vehicle's dashboard, thereby achieving a relatively fixed position between the entire on-board charging device 1 and the vehicle's dashboard.
