Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, and in particular to an auxiliary device. Background Technology

[0002] With the continuous development of technology, electronic products such as mobile phones and tablets have become increasingly popular and are used more frequently in people's daily lives and work. At the same time, various accessories that assist in the use of electronic products to expand their functions, such as chargers, power banks, and heat sinks, are also being used more frequently.

[0003] Existing electronic product accessories are generally divided into two types. One type has only one corresponding function. When users need to expand different functions or improve different performance, they need to use multiple accessories at the same time. However, different accessories may interfere with each other and affect normal use. The other type integrates multiple different functional modules into one accessory to form multiple different functions. When using this accessory, multiple functional modules will run at the same time. Users cannot run the functional modules they need according to the actual situation, which is inflexible and causes inconvenience to users. Utility Model Content

[0004] In view of this, the present invention provides an auxiliary device to solve the problem of inconvenience caused by the inflexibility of existing technology.

[0005] This application provides an auxiliary device, including a main functional module and an auxiliary functional module. The main functional module includes a first connecting structure, and the auxiliary functional module includes a second connecting structure. The main functional module and the auxiliary functional module are detachably connected through the first connecting structure and the second connecting structure, and can be used in a combined state and a separate state.

[0006] In the split-use state, the main functional module and the auxiliary functional module can be assembled and fixed with the electronic product through the first connection structure and the second connection structure, respectively;

[0007] In the combined use state, the main functional module and the auxiliary functional module are assembled and fixed together through the first connection structure and the second connection structure, and the whole is assembled and fixed to the electronic product through the first connection structure of the main functional module.

[0008] In some embodiments, the first connection structure and the second connection structure are magnetic structures, and in the combined use state, the main functional module and the auxiliary functional module are magnetically fixed together by the first connection structure and the second connection structure.

[0009] In some embodiments, an installation space is provided on the outside of the main functional module, and in the combined use state, the auxiliary functional module is located within the installation space.

[0010] In some embodiments, the main functional module includes a housing and a cover plate. The cover plate includes a covering portion that covers the housing and an extension portion located on one side of the covering portion. The extension portion protrudes out of the outer side of the housing. The mounting space is formed at the position of the extension portion. The first connecting structure is disposed on the cover plate.

[0011] In some embodiments, the first connection structure is annular and includes a first portion located in the cover portion and a second portion located in the extension portion. In the combined use state, the auxiliary function module is assembled into the installation space through the second connection structure and the second portion.

[0012] In some embodiments, the main functional module is a charging module and the auxiliary functional module is a heat dissipation module; or, the main functional module is a heat dissipation module and the auxiliary functional module is a charging module.

[0013] The cover plate is a heat-conducting plate, and the heat dissipation module includes a thermoelectric cooler, which is thermally connected to the heat-conducting plate.

[0014] In some embodiments, the heat dissipation module further includes a fan and a radiator, the radiator being disposed on the side of the thermoelectric cooler away from the heat-conducting plate and being thermally connected to the thermoelectric cooler, and the fan being used to drive airflow through the radiator.

[0015] In some embodiments, the main functional module is a charging module, and the auxiliary functional module includes at least one of a heat dissipation module, an expansion dock module, and a storage module. The auxiliary functional module and the charging module are connected by plugging in to form an electrical connection.

[0016] In some embodiments, the main functional module is a heat dissipation module, the auxiliary functional module is a charging module, the heat dissipation module is provided with a first conductive contact, and the charging module is provided with a corresponding second conductive contact. The first conductive contact and the second conductive contact are in contact to form an electrical connection.

[0017] In some embodiments, the heat dissipation module is provided with a first magnetic attractor near the first conductive contact, and the charging module is provided with a second magnetic attractor near the second conductive contact. In the combined use state, the first magnetic attractor and the second magnetic attractor are magnetically attracted to each other.

[0018] In some embodiments, the auxiliary device further includes a power supply line, which is detachably connected to the heat dissipation module. In the split-use state, the heat dissipation module is electrically connected to the electronic product through the power supply line.

[0019] In some embodiments, the heat dissipation module is provided with a first magnetic attractor near the first conductive contact, and one end of the power supply line is provided with a third conductive contact and a third magnetic attractor.

[0020] The auxiliary device provided by this utility model has a main functional module and an auxiliary functional module that can be detachably connected, allowing for both combined and separate use. When it is necessary to expand the functions of both the main and auxiliary functional modules simultaneously, they can be combined to form a combined use configuration, which can then be assembled onto the electronic product. When only the functions of the main or auxiliary functional module need to be expanded, they can be separated to form a separate use configuration, which can then be assembled onto the electronic product individually. This provides multiple different usage modes for users to choose from, allowing for greater flexibility and convenience. Furthermore, in the combined use configuration, the connection between the main and auxiliary functional modules is through a first connection structure and a second connection structure, and the connection between the device and the electronic product is also through the first connection structure. In the separate use configuration, the connection between the main and auxiliary functional modules and the electronic product is also through the first and second connection structures. This simplifies the structure of the main and auxiliary functional modules, reduces production difficulty and cost, and also helps to reduce the overall size of the auxiliary device.

[0036] Example 1

[0037] Please see Figures 1 to 3 This embodiment provides an auxiliary device 100 for installation on an electronic product 200 to expand the functionality of the electronic product 200 and facilitate user use. The electronic product 200 includes, but is not limited to, mobile phones, tablets, etc.

[0038] The auxiliary device 100 includes a main function module 10 and an auxiliary function module 12. The main function module 10 is used to assist the electronic product 200 in expanding its first function, and the auxiliary function module 12 is used to assist the electronic product 200 in expanding its second function. The first function and the second function are two different functions. The first function and the second function include, but are not limited to, heat dissipation function, charging function, storage function, and adding interface function.

[0039] The main functional module 10 is provided with a first connection structure 14, and the auxiliary functional module 12 is provided with a second connection structure 16. The main functional module 10 and the auxiliary functional module 12 are detachably connected through the first connection structure 14 and the second connection structure 16, so that the main functional module 10 and the auxiliary functional module 12 can be used in a combined state and a separate state. That is, when the main functional module 10 and the auxiliary functional module 12 are connected together through the first connection structure 14 and the second connection structure 16, they are in a combined state. The main functional module 10 and the auxiliary functional module 12 are installed as a whole into the electronic product 200 to simultaneously expand the first function and the second function. When the main functional module 10 and the auxiliary functional module 12 are separated, they are in a separate state. The main functional module 10 and the auxiliary functional module 12 can be installed separately into the electronic product 200 to expand the first function or the second function.

[0040] In the split-use state, the main functional module 10 and the auxiliary functional module 12 can be assembled and fixed to the electronic product 200 through the first connecting structure 14 and the second connecting structure 16, respectively. That is, the main functional module 10 is assembled to the electronic product 200 through the first connecting structure 14 and remains relatively fixed to the electronic product 200 to expand the first function, and the auxiliary functional module 12 is assembled to the electronic product 200 through the second connecting structure 16 and remains relatively fixed to the electronic product 200 to expand the second function.

[0041] In combined use, the main functional module 10 and the auxiliary functional module 12 are assembled together and kept relatively fixed through the first connection structure 14 and the second connection structure 16. The main functional module 10 and the auxiliary functional module 12 are assembled to the electronic product 200 through the first connection structure 14 and kept relatively fixed to the electronic product 200, so as to simultaneously expand the first function and the second function.

[0042] During use, when both the first function of the main function module 10 and the second function of the auxiliary function module 12 are needed simultaneously, the auxiliary device 100 can be used in combination and assembled as a whole into the electronic product 200. When only the first function of the main function module 10 or the second function of the auxiliary function module 12 is needed, the auxiliary device 100 can be used separately, forming two independent functional modules. Either the main function module 10 or the auxiliary function module 12 can then be assembled into the electronic product 200. This provides a variety of different usage methods for users to choose from, allowing them to select the appropriate method based on their actual needs. This makes the device more flexible and convenient to use. Meanwhile, in the combined use state, the connection between the main functional module 10 and the auxiliary functional module 12 is through the first connection structure 14 and the second connection structure 16, and the connection between the whole and the electronic product 200 is through the first connection structure 14. In the separate use state, the connection between the main functional module 10 and the auxiliary functional module 12 and the electronic product 200 is also through the first connection structure 14 and the second connection structure 16. This helps to simplify the structure of the main functional module 10 and the auxiliary functional module 12, reduce production difficulty and cost, and also helps to reduce the overall size of the auxiliary device 100.

[0043] The specific types of the first connecting structure 14 and the second connecting structure 16 are not limited. For example, they can be magnetic components or adhesives that can be repeatedly peeled off and stuck on, such as pressure-sensitive adhesive. In this application, the first connecting structure 14 and the second connecting structure 16 are magnetic structures. Magnetic structures also exist inside the electronic product 200. In the combined use state, the main functional module 10 and the auxiliary functional module 12 are magnetically fixed together via the first connecting structure 14 and the second connecting structure 16. The entire module is magnetically fixed to the back of the electronic product 200 via the first connecting structure 14, such as the back of a mobile phone. In the separate use state, the main functional module 10 is magnetically fixed to the back of the electronic product 200 via the first connecting structure 14, and the auxiliary functional module 12 is magnetically fixed to the back of the electronic product 200 via the second connecting structure 16. This magnetic connection method simplifies the connection and disconnection process, making it convenient for users. Furthermore, it does not affect the connection strength due to repeated disassembly and assembly, thus enhancing the reliability of the connection during use.

[0044] Please see Figure 2 and Figure 4 In one optional example, the magnetic attraction structure inside the electronic device is ring-shaped, and the first connecting structure 14 of the main functional module 10 is also ring-shaped accordingly. The shape of the first connecting structure 14 is adapted to the shape of the ring-shaped magnetic attraction structure inside the electronic device to enhance the magnetic attraction strength between the main functional module 10 and the electronic product 200. When the main functional module 10 and the auxiliary functional module 12 are used together, they are assembled together as a whole onto the back of the electronic product 200. The main functional module 10 and the auxiliary functional module 12 are relatively heavy. By adapting the shape of the first connecting structure 14 to the shape of the magnetic attraction structure inside the electronic device, the magnetic attraction strength between the main functional module 10 and the electronic product 200 is enhanced, thereby reducing the risk of the main functional module 10 and the auxiliary functional module 12 slipping off the electronic product 200 during use.

[0045] Understandably, in order to further enhance the magnetic attraction effect, when there are other magnetic components inside the electronic product 200 besides the ring magnetic attraction structure, corresponding magnetic components can also be set in the main functional module 10.

[0046] The first connecting structure 14 includes multiple magnetic units, which are arranged sequentially along a circular trajectory to form a circular structure.

[0047] In some embodiments, a mounting space 18 is provided on the outer side of the main functional module 10 for the installation of the auxiliary functional module 12. In the combined use state, the auxiliary functional module 12 is located within the mounting space 18. By providing the mounting space 18 on the main functional module 10 and installing the auxiliary functional module 12 within the mounting space 18, when the main functional module 10 and the auxiliary functional module 12 are assembled as a whole onto the outside of the electronic product 200, the auxiliary functional module 12 does not need to occupy the mounting position on the electronic product 200. Therefore, the size of the contact part between the main functional module 10 and the electronic product 200 can be designed to be larger, so that a first connection structure 14 can be provided on the main functional module 10, ensuring the connection strength between the main functional module 10 and the electronic product 200 in the combined use state and reducing the risk of detachment.

[0048] Optionally, the main functional module 10 is generally L-shaped. When it is fixed on the electronic product 200, part of the main functional module 10 extends along the length direction of the electronic product 200 and part extends along the thickness direction of the electronic product 200, thereby forming an L-shaped structure and thus forming the installation space 18.

[0049] Please see Figure 4 The main functional module 10 includes a housing 20 and a cover plate 22 connected to the housing 20. The cover plate 22 includes a covering portion 24 that covers the housing 20 and an extension portion 26 located on one side of the covering portion 24. The extension portion 26 protrudes from the outside of the housing 20 so that the housing 20 and the cover plate 22 cooperate to form an L-shaped structure. The mounting space 18 is formed at the position of the extension portion 26. The first connecting structure 14 is provided on the cover plate 22. When the main functional module 10 is assembled to the electronic product 200, the cover plate 22 is in contact with the back of the electronic product 200. By providing the extension portion 26 extending to the outside of the housing 20, in the combined use state, the auxiliary functional module 12 can be fixed to the extension portion 26 instead of being directly fixed to the electronic product 200. Therefore, a larger cover plate 22 can be formed so that the first connecting structure 14 can be provided on the cover plate 22.

[0050] The first connecting structure 14 is annular and includes a first portion 28 located in the cover portion 24 and a second portion 30 located in the extension portion 26. The second connecting structure 16 is correspondingly arranged with the second portion 30. That is, in the combined use state, the auxiliary functional module 12 is magnetically fixed to the installation space 18 through the second connecting structure 16 and the second portion 30. The first portion 28 and the second portion 30 are each semi-circular, and the two cooperate to form the annular first connecting structure 14.

[0051] The cover plate 22 has a groove 32 on the side near the housing 20, that is, the side away from the electronic product 200 in the use state. The groove 32 is annular. The first connecting structure 14 is installed into the groove 32, which improves the compactness between the cover plate 22 and the first connecting structure 14, and at the same time increases the contact area between the cover plate 22 and the first connecting structure 14, making it convenient to fix.

[0052] The method of fixing the first connecting structure 14 to the cover plate 22 is not limited. In an optional example, the first connecting structure 14 is fixed in the mounting groove of the cover plate 22 by adhesive.

[0053] Please see Figure 5 In this embodiment, the main functional module 10 is a charging module 34, such as a power bank, used to charge the electronic product 200 and also to provide the power required for the auxiliary functional module 12. The auxiliary functional module 12 is at least one of a heat dissipation module 36, a docking station module 38, and a storage module 40. The heat dissipation module 36 is used to dissipate heat from the electronic product 200, the docking station module 38 has multiple interfaces to expand the number of interfaces, and the storage module 40 has a data disk inside for storing data.

[0054] The heat dissipation module 36, the expansion dock module 38, and the storage module 40 are each provided with a second connection structure 16. Therefore, the heat dissipation module 36, the expansion dock module 38, and the storage module 40 can be used together with the charging module 34, or they can be assembled into the electronic product 200 for use. The heat dissipation module 36, the expansion dock module 38, and the storage module 40 can all be plugged into the charging module 34 to form an electrical connection.

[0055] The charging module 34 is not limited in the method of charging the electronic product 200; it can be wireless charging, wired charging, or a combination of both. In this embodiment, the auxiliary device 100 also includes a data cable 42, through which the charging module 34 is connected to the electronic product 200. When the heat dissipation module 36, the expansion dock module 38, or the storage module 40 is individually assembled to the electronic product 200, the heat dissipation module 36, the expansion dock module 38, or the storage module 40 can also be connected to the electronic product 200 via the data cable 42.

[0056] Please see Figure 6In an optional example, the auxiliary functional module 12 is a heat dissipation module 36, and the charging module 34 is provided with an installation space 18. In the combined use state, the charging module 34 is assembled and fixed to the electronic product 200 through the first connection structure 14, and the heat dissipation module 36 is assembled to the installation space 18 of the charging module 34 through the second connection structure 16 and the first connection structure 14. The semiconductor cooling chip 44 of the heat dissipation module 36 is thermally connected to the heat conduction plate 46 of the charging module 34, and the electronic product 200 is thermally connected to the heat conduction plate 46. At this time, the heat generated by the electronic product 200 and the charging module 34 can be transferred to the semiconductor cooling chip 44 through the heat conduction plate 46 to cool down the electronic product 200 and the charging module 34.

[0057] The heat dissipation module 36 includes a thermoelectric cooler 44 and a cover plate 22 serving as a heat-conducting plate 46. In combined use, the thermoelectric cooler 44 and the heat-conducting plate 46 are thermally connected. After the charging module 34 and the heat dissipation module 36 are assembled as a whole onto the electronic product 200, the heat-conducting plate 46 adheres to the electronic product 200, forming a thermally conductive connection. When the thermoelectric cooler 44 is operating, the side closest to the heat-conducting plate 46 absorbs heat. Therefore, the heat generated by the electronic product 200 and the charging module 34 during operation can be transferred to the thermoelectric cooler 44 through the heat-conducting plate 46, simultaneously cooling the charging module 34 and the electronic product 200 and preventing overheating from affecting their normal operation. When the heat dissipation module 36 is assembled separately onto the electronic product 200, the thermoelectric cooler 44 is thermally connected to the back of the electronic product 200, and in this case, the thermoelectric cooler 44 independently cools the electronic product 200.

[0058] The specific material of the heat-conducting plate 46 is not limited; it can be a heat-conducting adhesive plate or a heat-conducting metal plate, such as an aluminum plate.

[0059] The heat dissipation module 36 also includes a housing 47 and a heat sink 48 located inside the housing 47. The heat sink 48 is thermally connected to the end of the thermoelectric cooler 44 away from the heat-conducting plate 46, allowing the thermoelectric cooler 44 to transfer heat to the heat sink 48. The heat sink 48 includes multiple spaced-apart heat dissipation fins, which increase the contact area between the heat sink 48 and the air. After the electronic product 200 and the charging module 34 transfer heat to the thermoelectric cooler 44 through the heat-conducting plate 46, the thermoelectric cooler 44 transfers the heat to the heat sink 48, which then dissipates the heat to the external environment. Because the heat sink 48 has a larger contact area with the air than the thermoelectric cooler 44, its heat dissipation effect is better, thus improving the cooling effect of the thermoelectric cooler 44 on the charging module 34 and the electronic product 200.

[0060] Optionally, one end of the thermoelectric cooler 44 absorbs heat and is attached to the back of the heat-conducting plate 46 or the electronic product 200, while the other end is attached to the heat sink 48, increasing the contact area and improving heat conduction efficiency.

[0061] The heat dissipation module also includes a fan 50 located inside the housing 47. The housing 47 has an air inlet 52 and an air outlet 54. When the fan 50 is working, the outside airflow enters the heat dissipation module through the air inlet 52 and flows through the radiator 48 under the action of the fan 50, carrying away the heat on the radiator 48, and finally being blown out from the air outlet 54. The fan 50 can increase the airflow speed so that more air can come into contact with the radiator 48 per unit time, further improving the heat dissipation effect.

[0062] The heat sink 48 has a mounting hole 56 on the side away from the semiconductor cooling chip 44. The fan 50 is installed in the mounting hole 56, which enhances the compactness of the heat dissipation module structure and helps to reduce the overall size of the heat dissipation module.

[0063] The air inlet 52 is positioned opposite the fan 50 and located on one side of the fan 50's axial direction. There are two air outlets 54, which are located on opposite sides of the outer casing 47. The fan 50 is located between the two air outlets 54.

[0064] Example 2

[0065] The auxiliary device 300 provided in this embodiment differs from the auxiliary device in Embodiment 1 in that:

[0066] Please see Figures 7 to 9 In this embodiment, the main functional module is a heat dissipation module 60, and the auxiliary functional module is a charging module 62. The heat dissipation module 60 is provided with a first connecting structure 64, and an installation space 66 is provided on the outside of the heat dissipation module 60. The charging module 62 is provided with a second connecting structure 68. The charging module 62 is assembled and fixed to the installation space 66 of the heat dissipation module 60 through the cooperation of the second connecting structure 68 and the first connecting structure 64. The heat dissipation module 60 is assembled and fixed to the electronic product 400 through the first connecting structure 64. The heat dissipation module 60 includes a semiconductor cooling chip 70 and a heat-conducting plate 72, which is the cover plate of the main functional module. The semiconductor cooling chip 70 and the heat-conducting plate 72 are thermally connected. In the combined use state, the electronic product 400 and the charging module 62 are thermally connected to the heat-conducting plate 72, so that the heat generated by the electronic product 400 and the charging module 62 can be transferred to the semiconductor cooling chip 70 through the heat-conducting plate 72.

[0067] In this embodiment, the heat dissipation module 60 further includes a housing 74 and a cover plate 76 connected to the housing 74. The first connecting structure 64 is disposed on one side of the heat-conducting plate 72, and the cover plate 76 is fitted with the extension 78 of the heat-conducting plate 72 to cover the first connecting structure 64, so that the first connecting structure 64 is located between the extension 78 and the cover plate 76, preventing it from being exposed. Optionally, the cover plate 76 and the housing 74 are integrally formed.

[0068] In this embodiment, the heat dissipation module 60 is provided with a first conductive contact 80, which is located on the side of the housing 74 near the mounting space 66. The charging module 62 is provided with a corresponding second conductive contact 82. In the combined use state, the charging module is installed in the mounting space 66, and the first conductive contact 80 and the second conductive contact 82 come into contact to form an electrical connection, thereby using the charging module 62 to provide the heat dissipation module 60 with the power required for operation.

[0069] The heat dissipation module 60 is provided with a first magnetic 84 near the first conductive contact 80, and the charging module 62 is provided with a second magnetic 86 near the second conductive contact 82. The first magnetic component and the second magnetic 86 are correspondingly arranged. In the combined use state, the first conductive contact 80 and the second conductive contact 82 are in contact to form an electrical connection. The first magnetic 84 and the second magnetic 86 magnetically cooperate to enhance the stability of the electrical connection between the charging module 62 and the heat dissipation module 60.

[0070] In an optional example, there are two first magnetic accommodators 84 and two second magnetic accommodators 86. The two first magnetic accommodators 84 are respectively spaced apart on opposite sides of the first conductive contact 80, and the two second magnetic accommodators 86 are respectively spaced apart on opposite sides of the second conductive contact 82, so as to further enhance the stability of the electrical connection between the charging module 62 and the heat dissipation module 60.

[0071] Please see Figure 8 and Figure 10 In this embodiment, the auxiliary device 300 further includes a power supply line 88, which is detachably connected to the heat dissipation module 60. In the separate use state, when the heat dissipation module 60 is assembled and fixed to the electronic product 400 through the first connecting structure 64, the heat dissipation module 60 is electrically connected to the electronic product 400 through the power supply line 88, and the electronic product 400 supplies power to the heat dissipation module 60. Since the power supply line 88 and the heat dissipation module 60 are detachably connected, in the combined use state, the power supply line 88 can be separated from the heat dissipation module 60, and the heat dissipation module 60 can be directly powered by the charging device, preventing the power supply line 88 from interfering with the installation of the charging module 62.

[0072] The specific connection method between the power supply line 88 and the heat dissipation module 60 is not limited, as long as it can provide electrical connection and detachability. For example, it can be connected by contact and magnetic attraction, or by plugging in.

[0073] In this embodiment, one end of the power supply line 88 is provided with a third conductive contact 90 and a third magnetic chuck 92. The third conductive contact 90 corresponds to the first conductive contact 80 of the heat dissipation module 60, and the third magnetic chuck 92 corresponds to the first magnetic chuck 84 of the heat dissipation module 60. When the power supply line 88 is connected to the heat dissipation module 60, the third conductive contact 90 contacts the first conductive contact 80, so that the heat dissipation module 60 and the power supply line 88 form an electrical connection. The third magnetic chuck 92 magnetically engages with the first magnetic chuck 84 to enhance the stability of the electrical connection between the heat dissipation module 60 and the power supply line 88, and at the same time form a detachable effect.

[0074] Optionally, there are two third magnetic accumulators 92. The two third magnetic accumulators 92 are respectively spaced apart on opposite sides of the third conductive contact 90, and the two third magnetic accumulators 92 correspond to the two first magnetic accumulators 84 respectively, further enhancing the stability of the electrical connection between the heat dissipation module 60 and the power supply line 88.

[0075] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
