Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Each specific technical feature described in the specific embodiments can be combined in any suitable manner without conflict. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination methods of each specific technical feature in the present utility model will not be described separately.

[0028] In the following description, the terms "first", "second", etc. involved are only used to distinguish different objects, and do not indicate that there are any same or related relationships between the objects. It should be understood that the orientation descriptions "above", "below", "outside", and "inside" involved are all the orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which may or may not be the left and right directions in the normal use state.

[0029] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element. "Plurality" means greater than or equal to two.

[0030] The embodiment of the present utility model provides a portable adapter for connecting to an electronic device. The portable adapter can be used as a power supply device to supply power to the electronic device. For example, the portable adapter can be a mobile power supply. The portable adapter can also convert the current of the power supply device so that the power supply device can supply power to the electronic device. For example, the portable adapter can be an in-vehicle inverter connected to a vehicle, and the in-vehicle inverter converts the current on the vehicle into a current available for the electronic device. The portable adapter can also be only used as a current conversion device to connect the electronic device and another device. For example, the portable adapter can be a docking station, and the docking station can be connected to the data interface of a laptop computer to convert one data interface on the laptop computer into multiple interfaces available for the electronic device, so as to expand the number and types of data interfaces. In addition, when the docking station is plugged into a charging position, such as when the docking station is plugged into the armrest box or cigarette lighter of a vehicle, while expanding the number and types of data interfaces, the docking station can also output the electrical energy in the vehicle to the electronic device to charge the electronic device.

[0031] It should be noted that the types of electronic devices include, but are not limited to, mobile phones, tablet computers, laptop computers, mobile power supplies, projectors, speakers, and headphones. As long as the interface of the electronic device can be plugged into the portable adapter in the embodiments of the present invention. It can be understood that the type of application scenario of the embodiments of the present invention does not limit the structure of the portable adapter of the embodiments of the present invention.

[0032] For ease of understanding, the portable adapter will be explained below as a mobile power supply. Based on the background technology, during the factory quality inspection stage, mobile power supplies that fail the quality inspection need to be reworked. For example, the data cable and / or circuit board are damaged, and the mobile power supply does not form a charging circuit for supplying power to the electronic device; or, the housing of the mobile power supply is damaged, affecting the user experience. The related technical means fix the data cable by gluing or by a gland with screws. However, after gluing, it is not convenient to disassemble and assemble the data cable; the gland with screws requires screwing multiple screws, and the disassembly and assembly efficiency is not high. Therefore, the above two implementation methods are not conducive to the assembly of the data cable, nor to the rework of the portable adapter, and the labor cost is relatively high.

[0033] As Figure 1 and Figure 2 shown, the portable adapter includes a housing 100, electrical components 200, a data cable 300, and a clamping member 400. An installation cavity 131 is formed inside the housing 100. The electrical components 200 are arranged in the installation cavity 131. One end of the data cable 300 is connected to the electrical components 200 in the installation cavity 131, and the other end of the data cable 300 extends out of the installation cavity 131 and is used to connect to an electronic device. It should be noted that the interface types of the other end of the data cable 300 include, but are not limited to, USB interfaces, Type-C interfaces, and Lightning interfaces. The data cable 300 can be set as one cable, two cables, or three cables to have one or more of the USB interface, Type-C interface, and Lightning interface. That is, the portable adapter provided by the embodiments of the present invention can supply power to multiple electronic devices at the same time, and the interface types of the multiple electronic devices can be the same or different.

[0034] As Figure 3 and Figure 4As shown, the housing 100 is provided with a limiting portion located in the installation cavity 131; the data cable 300 includes a fixing portion 310 at least partially located in the installation cavity 131. The fixing portion 310 can be simply understood as the SR portion of the data cable 300. Here, SR is the abbreviation of STRAIN RELIEF, which is used to eliminate the stress of the wire and prevent the core wire at the wire connection from breaking. It is made of rubber or other materials with different strengths for different wires. The clamping member 400 is clamped with the limiting portion and the fixing portion 310 to limit at least part of the fixing portion 310 in the installation cavity 131, reducing the possibility that the data cable 300 loosens or detaches from the housing 100, thereby affecting the charging stability of the electronic device. The fixing portion 310 of the data cable 300 is connected to the housing 100 through the clamping member 400, and the connection forms between the clamping member 400 and the limiting portion, and between the clamping member 400 and the fixing portion 310 are both clamping connections. By disassembling and assembling the clamping member 400, the data cable 300 can be smoothly detached from the housing 100 or the fixing portion 310 of the data cable 300 can be fixedly connected to the housing 100. There is no need to glue the data cable 300, nor to screw the screws to disassemble and assemble the data cable 300, which simplifies the disassembly and assembly operation of the data cable 300, facilitates the assembly of the portable adapter, and also facilitates the rework of the portable adapter.

[0035] Specifically, the limiting portion can be a groove-shaped structure for cooperating with the clamping member 400, or a protruding structure such as a rib or a tongue; correspondingly, the fixing portion 310 can also be provided with a groove-shaped structure for cooperating with the clamping member 400, or a protruding structure such as a rib or a tongue. The present application does not limit the specific structures of the limiting portion and the fixing portion 310, as long as the clamping member 400 can be clamped with the limiting portion and the fixing portion 310 to limit the position of the fixing portion 310, thereby realizing the fixed connection between the data cable 300 and the housing 100.

[0036] It can be understood that, as Figure 2 shown, when the portable adapter is set as a mobile power supply, the electrical components 200 include a circuit board 210 and a rechargeable battery 220. In Figure 3 the schematic diagram shown, in order to show the clamping member 400, part of the structure of the housing 100 (the bottom cover 140) and part of the rechargeable battery 220 are omitted.

[0037] The portable adapter provided by the embodiment of the present utility model includes a housing 100, electrical components 200, a data cable 300, and a clamping member 400. An installation cavity 131 is formed inside the housing 100, and a limiting portion is provided in the installation cavity 131. The electrical components 200 are arranged in the installation cavity 131. One end of the data cable 300 is connected to the electrical components 200 in the installation cavity 131, and the other end extends out of the installation cavity 131 and is used to connect to an electronic device. The data cable 300 includes a fixing portion 310 at least partially located in the installation cavity 131. The clamping member 400 is clamped with the limiting portion and the fixing portion 310 to limit the position of the fixing portion 310. With such a setting, at least part of the fixing portion 310 is located in the installation cavity 131, and the position of the fixing portion 310 is fixed by the clamping member 400. Through the clamping member 400, the fixed connection between the data cable 300 and the housing 100 can be realized. Then, by removing the clamping member 400, the data cable 300 can be separated from the housing 100. Compared with fixing by gluing, the setting of the clamping member 400 enables the detachable connection between the data cable 300 and the housing 100, and the disassembly and assembly operations of the data cable 300 are more convenient. Compared with fixing the data cable 300 by a gland with screws, the clamping member 400 is clamped with the limiting portion and the fixing portion 310, without the need to screw the screws, and the disassembly and assembly efficiency is higher, reducing the labor cost. Moreover, there is a large contact area between the clamping member 400 and the housing 100, and the fixing stability is good, and it will not loosen randomly. In summary, the setting of the clamping member 400 facilitates the disassembly and assembly of the data cable 300 of the portable adapter, simplifies the assembly operation of the portable adapter, and also facilitates the separation of the data cable 300 and the housing 100 in the rework processing stage, reducing the difficulty of rework processing of the portable adapter.

[0038] In some embodiments, as Figure 4 and Figure 5 shown, the limiting portion is set as a limiting groove 110, a groove 311 is formed on the fixing portion 310, and the clamping member 400 is inserted into the limiting groove 110 and the groove 311. With such a setting, there is no need to open a groove on the clamping member 400, which helps to improve the structural strength of the clamping member 400. At the same time, the outer surface of the clamping member 400 can be kept relatively neat, and the structure of the clamping member 400 is relatively simple, which helps to realize the batch processing of the clamping member 400. The clamping member 400 is inserted into the limiting groove 110 and the groove 311 at the same time. By pulling out or inserting the clamping member 400, the disassembly and assembly of the data cable 300 can be realized, and the operation is simple and easy to implement.

[0039] Specifically, as Figure 4 and Figure 5As shown, the fixing part 310 can have grooves 311 formed on one side (or opposite sides), can have grooves 311 formed at one end (or opposite ends), or can have grooves 311 formed at one end (or opposite ends) and one side (or opposite sides). Correspondingly, the limiting groove 110 can be provided on one side (or opposite sides) of the fixing part 310, can be provided at one end (or opposite ends) of the fixing part 310, or can be provided at one end (or opposite ends) and one side (or opposite sides) of the fixing part 310. It can be understood that the above "one side" refers to the orientation in the horizontal direction and also the orientation in the N1 direction as shown; the above "one end" refers to the orientation in the longitudinal direction and also the orientation in the N2 direction as shown. The positions of the groove 311 and the limiting groove 110 affect the shape of the engaging part 400. For example, when there are limiting grooves 110 and grooves 311 on both opposite sides of the fixing part 310, the engaging part 400 is generally U-shaped or is provided as two parallel plug rods; when there are limiting grooves 110 and grooves 311 at one end and one side of the fixing part 310, the engaging part 400 is generally L-shaped. It should be noted that the specific positions of the groove 311 and the limiting groove 110 are not limited in this application, as long as the engaging part 400 can be inserted into the limiting groove 110 and the groove 311. Figure 5 As shown, the orientation in the N1 direction; the above "one end" refers to the orientation in the longitudinal direction and also the orientation in the N2 direction as shown. Figure 5 As shown. The positions of the groove 311 and the limiting groove 110 affect the shape of the engaging part 400. For example, when there are limiting grooves 110 and grooves 311 on both opposite sides of the fixing part 310, the engaging part 400 is generally U-shaped or is provided as two parallel plug rods; when there are limiting grooves 110 and grooves 311 at one end and one side of the fixing part 310, the engaging part 400 is generally L-shaped. It should be noted that the specific positions of the groove 311 and the limiting groove 110 are not limited in this application, as long as the engaging part 400 can be inserted into the limiting groove 110 and the groove 311.

[0040] In some embodiments, such as Figure 4 and Figure 5 As shown, grooves 311 and limiting grooves 110 are respectively provided on both opposite sides of the fixing part 310 one by one. That is, two grooves 311 are formed on the fixing part 310, and the two grooves 311 are respectively arranged on the opposite sides of the fixing part 310; the limiting parts are provided as two limiting grooves 110, and the two limiting grooves 110 are also respectively arranged on the opposite sides of the fixing part 310. Then it can be understood that the engaging part 400 is generally U-shaped or is provided as two parallel plug rods. With this setting, the two opposite positions of the fixing part 310 in the N1 direction are both limited by the engaging part 400, which helps the engaging part 400 to stably limit the position of the fixing part 310, so as to improve the installation stability of the data cable 300 and reduce the possibility of the data cable 300 loosening or detaching from the installation cavity 131. In addition, the engaging part 400 can be pulled out or inserted in the N2 direction, and there is no need to coaxially sleeve the engaging part 400 on the fixing part 310, that is, the engaging part 400 can be synchronously inserted into the limiting groove 110 and the groove 311 without being inserted into the limiting groove 110 and the groove 311 in stages respectively, further simplifying the assembly operation of fixedly connecting the fixing part 310 and the housing 100 and facilitating the disassembly and assembly of the data cable 300.

[0041] In some embodiments, such as Figure 4 and Figure 5As shown, the snap-in part 400 includes a connecting part 420 and two snap-in arms 410. The two snap-in arms 410 are arranged at intervals, and the connecting part 420 is arranged at the same end (upper end) of the two snap-in arms 410, that is, the snap-in part 400 is generally U-shaped. A receiving groove 411 is formed inside the connecting part 420 and the two snap-in arms 410. The fixing part 310 is inserted into the receiving groove 411, and an insertion opening 412 communicating with the receiving groove 411 is formed at one end (lower end) of the two snap-in arms 410 away from the connecting part 420. Inserting the snap-in part 400 along the N2 direction can make the outer sides of the snap-in arms 410 inserted into the limiting grooves 110 and the inner sides inserted into the grooves 311, thereby limiting the position of the fixing part 310 and realizing the fixed connection between the fixing part 310 and the housing 100. Compared with the snap-in part 400 having two parallel insertion rods, the snap-in part 400 provided in the embodiment of the present invention is generally U-shaped, and the snap-in part 400 can be inserted or pulled out in one step with one operation. The disassembly and assembly operation of the snap-in part 400 is more concise, making the disassembly and assembly operation of the data cable 300 easier to achieve.

[0042] In some embodiments, as Figure 5 shown, the two grooves 311 are respectively arranged through in the width direction of the fixing part 310, and the width of the fixing part 310 is greater than the thickness of the fixing part 310. It can be understood that the N2 direction shown in the schematic diagram of the present application is the width direction of the fixing part 310, and correspondingly, the N3 direction shown in the schematic diagram of the present application is the thickness direction of the fixing part 310. The fixing part 310 has grooves 311 opened in the part with a larger size, so that the length of the grooves 311 is longer, and then the length of the snap-in arms 410 is longer, the contact area between the grooves 311 and the snap-in arms 410 is larger, and the force arm for the snap-in part 400 to limit the fixing part 310 is larger, improving the installation stability of the fixing part 310.

[0043] In some embodiments, as Figure 4 and Figure 5As shown, the housing 100 is provided with a first blocking rib 111 and a second blocking rib 112 located in the installation cavity 131. The first blocking rib 111 and the second blocking rib 112 are spaced from each other and are both spaced from the first inner wall surface 113 of the housing 100. The first inner wall surface 113 is provided with a wire passing hole 1131 for the fixing portion 310 to pass through. The wire passing hole 1131 is located between the first blocking rib 111 and the second blocking rib 112. For the convenience of understanding, the passing direction of the fixing portion 310 is defined as the N3 direction. It can be understood that the passing direction of the fixing portion 310 is also the length direction of the fixing portion 310. That is to say, along the N3 direction, the fixing portion 310 passes through the wire passing hole 1131 between the first blocking rib 111 and the second blocking rib 112. In the passing direction of the fixing portion 310, a limiting groove 110 is respectively formed between the first blocking rib 111 and the first inner wall surface 113, and between the second blocking rib 112 and the first inner wall surface 113. That is, a limiting groove 110 is formed between the first blocking rib 111 and the first inner wall surface 113, and one of the two clamping arms 410 abuts between the first blocking rib 111 and the first inner wall surface 113; a limiting groove 110 is formed between the second blocking rib 112 and the first inner wall surface 113, and the other of the two clamping arms 410 abuts between the second blocking rib 112 and the first blocking rib 111. With such a setting, the groove wall of the limiting groove 110 formed by the first inner wall surface 113 is utilized, reducing the processing difficulty and forming difficulty of the limiting groove 110 and facilitating the processing and forming of the limiting groove 110; and the area of the first inner wall surface 113 is relatively large and is convenient for abutting against the clamping member 400, so that the clamping member 400 can more stably limit the position of the fixing portion 310.

[0044] In some embodiments, as Figure 4 and Figure 5 shown, the housing 100 is further provided with a third blocking rib 120 located in the installation cavity 131. In the passing direction of the fixing portion 310, the third blocking rib 120 abuts against the surface of the fixing portion 310 away from the first inner wall surface 113. It can be understood that the third blocking rib 120 forms the left limit of the fixing portion 310, and the first inner wall surface 113 abuts against the clamping member 400 to form the right limit of the fixing portion 310. The degrees of freedom of the fixing portion 310 in the N3 direction are all restricted, reducing the possibility of the fixing portion 310 moving left and right along the Figure 5 shown N3 direction, enabling the clamping member 400 to maintain the connection with the fixing portion 310 and the limiting groove 110, and further enabling the fixing portion 310 to maintain the fixed connection with the housing 100, which helps to improve the installation stability of the fixing portion 310.

[0045] In some embodiments, as Figure 2As shown, the housing 100 includes a face cover 130 and a bottom cover 140. The face cover 130 forms an installation cavity 131 and an opening 132 communicating with the installation cavity 131. The bottom cover 140 is detachably connected to the face cover 130. The bottom cover 140 is disposed at the opening 132 and closes the installation cavity 131. The housing 100 is detachably assembled by the bottom cover 140 and the face cover 130. By disassembling and assembling the bottom cover 140, the installation cavity 131 can be opened or closed, which is convenient for assembling electrical components 200 and / or data lines 300 in the installation cavity 131. Combined with Figure 5 As shown, the insertion port 412 of the clamping member 400 faces away from the bottom cover 140, that is, the connecting portion 420 of the clamping member 400 is adjacent to the bottom cover 140. The insertion port 412 of the clamping member 400 is disposed at one end of the connecting portion 420 away from the bottom cover 140. That is to say, the connecting portion 420 is disposed at the opening 132, and the insertion port 412 is disposed below the connecting portion 420 and below the opening 132. Then it can be understood that the insertion direction of the clamping member 400 is Figure 5 As shown, from top to bottom, and the extraction direction of the clamping member 400 is Figure 5 As shown, from bottom to top. The space at the opening 132 can be used to insert or extract the clamping member 400 to realize the disassembly and assembly of the clamping member 400.

[0046] Specifically, as Figure 2 shown, the face cover 130 and the bottom cover 140 can be detachably connected by means of clamping, interlocking of connecting members (such as screws, bolts, etc.), etc. The present application does not limit the detachable connection method of the face cover 130 and the bottom cover 140, as long as the relative positions of the face cover 130 and the bottom cover 140 can be stabilized.

[0047] In some embodiments, as Figure 2 and Figure 8 shown, a retaining edge 141 is convexly provided on the side of the bottom cover 140 facing the installation cavity 131. The retaining edge 141 can block the clamping member 400. That is, the bottom surface of the bottom cover 140 is convexly provided with the retaining edge 141, and the retaining edge 141 is disposed in the extraction direction of the clamping member 400. Among them, it can be understood that Figure 6 is the front view of the portable adapter provided by the embodiment of the present invention, Figure 7 is Figure 6 the cross-sectional view in the B-B direction in Figure 8 is Figure 7 the enlarged view at C in

[0048] Specifically, referring to Figure 8, the retaining edge 141 can abut against the connecting portion 420, or the retaining edge 141 can be spaced apart from the connecting portion 420. However, regardless of whether there is a gap between the retaining edge 141 and the connecting portion 420, the retaining edge 141 is disposed above the connecting portion 420 and can block the connecting portion 420 to maintain the installation stability of the engaging member 400 and thus the installation stability of the data cable 300. In the embodiment where the retaining edge 141 abuts against the connecting portion 420, when the bottom cover 140 is installed in the direction from top to bottom, the retaining edge 141 also abuts against the connecting portion 420 in the direction from top to bottom, and the retaining edge 141 presses down the engaging member 400 to make the engaging member 400 inserted in place, thereby completing the assembly of the engaging member 400. No manual calibration is required, the operation is simple, and the installation is convenient.

[0049] In some embodiments, as Figure 8 shown, the fixing portion 310 further defines a first slot 312, and a first rib 142 protrudes from the side of the bottom cover 140 facing the installation cavity 131. The first rib 142 is inserted into the first slot 312. It can be understood that the first rib 142 forms an upper limit position of the fixing portion 310 and can assist the engaging member 400 to limit the position of the fixing portion 310 in the N3 direction.

[0050] In some embodiments, as Figure 8 shown, the fixing portion 310 further defines a second slot 313, and a second rib 133 protrudes from the side of the face cover 130 facing the opening 132. The second rib 133 is inserted into the second slot 313. It can be understood that the second rib 133 forms a lower limit position of the fixing portion 310 and can assist the engaging member 400 to limit the position of the fixing portion 310 in the N3 direction.

[0051] In some possible implementation schemes, the fixing portion 310 can define the first slot 312 and the second slot 313 at the same time, and the face cover 130 is provided with the first rib 142, and the bottom cover 140 is provided with the second rib 133 to form the upper limit position and the lower limit position of the fixing portion 310 at the same time. In addition, the first rib 142 is inserted into the first slot 312, and the second rib 133 is inserted into the second slot 313, and can Figure 8Abutted against the fixing part 310 in the left-right direction as shown, which further restricts the freedom of movement of the fixing part 310 in the N3 direction. The first rib 142 and the second rib 133 cooperate with the engaging part 400 to limit the position of the fixing part 310, so as to limit the freedom of movement of the fixing part 310 in multiple positions, making the fixing part 310 maintain a high installation stability, improving the charging stability of the mobile power supply, and prolonging the service life of the mobile power supply. In addition, the first rib 142 and the second rib 133 share the stress moment of the engaging part 400, and also prolong the service life of the engaging part 400. Of course, in some other possible implementation schemes, the fixing part 310 may also only be provided with the first slot 312, and the face cover 130 is provided with the first rib 142 that cooperates with the first slot 312; the fixing part 310 may also only be provided with the second slot 313, and the bottom cover 140 is provided with the second rib 133 that cooperates with the second slot 313, that is to say, even if only one of the first rib 142 and the second rib 133 is provided, it can also assist the engaging part 400 to limit the position of the fixing part 310.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
