[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] refer to Figure 1-4 In one embodiment, a power supply device 100 includes a housing 10 and a battery module 20 (see...). Figure 7 ) and circuit board module 30 (see Figure 7 The circuit board module 30 is electrically connected to the battery module 20. In this embodiment, the power supply device 100 is a car emergency jump starter. It should be noted that those skilled in the art will realize after reading the following that the technical solution of this patent application is not limited to car emergency jump starters, but can be applied to other types of power supplies.

[0040] In one embodiment, both the battery module 20 and the circuit board module 30 are disposed inside the housing 10. For example, the inner surface of the housing 10 is provided with a support structure to fix the battery module 20 and the circuit board module 30. Alternatively, the housing 10 is provided with an independent bracket to which both the battery module 20 and the circuit board module 30 are fixed. Yet another option is to fix the battery module 20 to the inner surface of the housing 10 using adhesive or tape.

[0041] In another embodiment, the power supply device 100 further includes an inner housing 40, which is housed within the outer housing 10, and the battery module 20 and the circuit board module 30 are both disposed inside the inner housing 40.

[0042] In any of the above embodiments, in order to protect the battery module 20 and prevent the battery module 20 from negatively affecting the circuit board module 30, the circuit board module 30 and the battery module 20 are separated by a partition 50 (see...). Figure 8The partition 50 is separated and located in different first and second spaces. That is, the partition 50 can be disposed inside the outer shell 10, and the inner shell 40 is not disposed inside the outer shell 10 at this time. The partition 50 divides the internal space of the outer shell 10 into the first space and the second space; the partition 50 can also be disposed inside the inner shell 40, dividing the internal space of the inner shell 40 into the first space and the second space. The following description uses the example of the partition 50 also being disposed inside the inner shell 40, but those skilled in the art will recognize that this is merely an example and does not constitute a limitation on the arrangement of the partition 50.

[0043] refer to Figures 8 to 12 The inner shell 40 includes a first inner shell 41. The internal space of the first inner shell 41 includes a first space 411 and a second space 412 separated by a partition 50. The circuit board module 30 is housed in the first space 411, and the battery module 20 is housed in the second space 412.

[0044] refer to Figure 3 and Figure 4 In one embodiment, the outer casing 10 includes a hollow body 11, which is generally elongated cuboid in shape. One end of the body 11 is open along its length, and the other end is closed. During assembly, the inner casing 40 can be inserted into the interior of the body 11 through the open end. In one embodiment, the outer casing 10 further includes a first end cap 12 connected to the open end and a second end cap 13 connected to the closed end.

[0045] In one embodiment, the inner shell 40 has a shape and structure adapted to the receiving space inside the body 11 of the outer shell 10, and the inner shell 40 is generally an elongated cuboid. (See also...) Figure 12 In one embodiment, the first inner shell 41 is generally an elongated and hollow cuboid, comprising four interconnected sidewalls 413, 414, 415, and 416. A partition 50 is interconnected with one or all of the inner surfaces of the sidewalls 413, 414, 415, and 416, thereby dividing the internal space of the first inner shell 41 into two parts: a first space 411 and a second space 412. Figure 12 From the perspective of its height direction (i.e., along the...), the first inner shell 41... Figure 12 The top end of the first space 411 (in the Z direction) is the opening end of the first space 411, while the bottom end of the first inner shell 41 in its height direction is the opening end of the second space 412. Through the above-mentioned opening ends, the circuit board module 30 and the battery module 20 can be placed into the first space 411 and the second space 412.

[0046] In one embodiment, the partition 50 and the sidewalls 413, 414, 415, and 416 of the first inner shell 41 are integrally formed, for example, by injection molding. In another embodiment, the partition 50 can be connected to the sidewalls 413, 414, 415, and 416 by conventional connecting means (e.g., screws, snaps).

[0047] In one embodiment, the surface of the separator 50 facing the battery module 20 (i.e., Figure 13 The lower surface 51) is a smooth surface. At this time, one end of the battery module 20 (i.e. Figure 13 The top end 21) can be fixed to the lower surface 51 with glue or tape. At this time, the battery module 20 is located between the separator 50 and the bottom plate 14 of the housing 10.

[0048] In another embodiment, the inner shell 40 further includes a second inner shell 42 (see...) Figure 9 The second inner shell 42 is connected to and covers the opening end of the second space 412. At this time, the battery module 20 is located between the separator 50 and the second inner shell 42. The second inner shell 42 provides protection for the battery module 20, so that the battery module 20 will not be damaged by accidental impact when the inner shell 40 is inserted into the outer shell 10.

[0049] In one embodiment, the partition 50 is provided with a through hole 52 connecting the first space 411 and the second space 412 (see...). Figure 12 The through-hole 52 allows the circuit board module 30 located in the first space 411 to be exposed in the second space 412, enabling the battery module 20 and the circuit board module 30 to establish an electrical connection, the method of establishing the electrical connection will be described in detail later. The location of the through-hole 52 can be selected according to actual needs. In one embodiment, the through-hole 52 is located near one end of the first inner shell 41, specifically near the side wall 413 of the first end cover 12 facing the outer shell 10. The purpose of this arrangement is to shorten the wiring distance, which will be described in detail later. In one embodiment, the through-hole 52 is completely located on the partition 50, that is, the sides of the through-hole 52 are all located on the partition 50. In another embodiment, the through-hole 52 is defined by the partition 50 and one, two, or three of the side walls 413, 414, 415, and 416 of the first inner shell 41, that is, the sides of the through-hole 52 are respectively located on the partition 50 and one, two, or three of the side walls 413, 414, 415, and 416.

[0050] refer to Figure 8 and Figure 9 In one embodiment, the power supply device 100 further includes a connector located at one end of the first inner housing 41, and the first surface 31 of the circuit board module 30 (see...) Figure 7 and Figure 10Facing the through-hole 52, the connector is electrically connected to the first surface 31 of the circuit board module 30 or to the battery module 20 via a wire passing through the through-hole 52. In this embodiment, the connector includes a first socket 61 and a second socket 62 for charging and / or discharging, both of which are electrically connected to the first surface 31 of the circuit board module 30 via a wire passing through the through-hole 52. The first socket 61 and the second socket 62 are used to connect to other power sources to charge the battery module 20, or to connect to other electrical devices to charge other electrical devices. The first socket 61 and the second socket 62 are two different types of USB sockets (i.e., a USB Type-A socket and a USB Type-C socket). It is understood that in other embodiments, the first socket 61 and the second socket 62 may use other types of connectors as needed. In another embodiment, the connector may also include a current output interface, which is electrically connected to the battery module 20 via a wire passing through the through-hole 52. In this embodiment, the user can insert the starter clip assembly 200 (see...) Figure 1 The plug is inserted into the current output interface, and the two starting clips 210 and 220 of the starting clip assembly 200 (see...) Figure 1 After being correctly connected to the positive and negative terminals (or metal body) of the car battery, the power supply unit 100 can output the instantaneous large current required to start the car starter motor.

[0051] In one embodiment, the first socket 61 and the second socket 62 are fixed to a circuit board 63, which is fixed to the opening end of the second space 412 of the first inner shell 41 and near the side wall 413 of the first inner shell 41 facing the first end cap 12 of the outer shell 10. The side wall 413 and the second inner shell 42 together define a through-hole through which the first socket 61 and the second socket 62 pass. (See also...) Figure 7 In one embodiment, the circuit board 63 is provided with first female connectors 631 and 632, which are respectively electrically connected to the first socket 61 and the second socket 62. The first surface 31 of the circuit board module 30 is provided with two corresponding first female connectors 631 and 632. The first female connector 631 on the circuit board 63 and the first female connector 631 on the circuit board module 30 are electrically connected through connecting wires with male connectors at both ends. The second female connector 632 on the circuit board 63 and the second female connector 632 on the circuit board module 30 are electrically connected through connecting wires with male connectors at both ends. In this way, the first socket 61 and the second socket 62 are electrically connected to the circuit board module 30, and the circuit board module 30 can communicate with the first socket 61 and the second socket 62 to negotiate a charging protocol. This allows the first socket 61 or the second socket 62 to charge the battery module 20 when connected to a charger, or to charge the electrical device when connected to an electrical device.

[0052] In one embodiment, the first surface 31 of the circuit board module 30 is further provided with a power supply female connector 64 and an NTC female connector 65. The circuit board module 30 can be electrically connected to the battery module 20 via a connecting cable with one end electrically connected to the battery module 20 and the other end having a plug that mates with the power supply female connector 64, allowing the battery module 20 to supply power to the circuit board module 30 and the electronic components electrically connected to it. Furthermore, an NTC plug 66 (see [link to NTC connector]) is provided, with one end electrically connected to the battery module 20 and the other end having a plug that mates with the NTC female connector 65. Figure 9 The circuit board module 30 can communicate with the temperature sensor in the battery module 20 via the connection line. For example, the temperature sensor can be a negative temperature coefficient thermistor, whose resistance decreases as the temperature rises. The circuit board module 30 can read the resistance value of the temperature sensor and calculate the actual temperature of the battery module 20.

[0053] In one embodiment, the power supply 100 is a vehicle emergency jump starter, and therefore includes a current output interface 67 electrically connected to the battery module 20. The outer surface of the first inner housing 41 (specifically, the side wall 414) is provided with a through hole 4141 for exposing the current output interface 67 (see...). Figure 9 and Figure 12 The housing 10 is provided with a groove 15 that allows the current output interface 67 to be exposed (see...). Figure 3 and Figure 17 ), a cover plate 16 (see Figure 1 and Figure 3 The cover plate 16 is movably connected to the slide 15. When pushed by the user, the cover plate 16 can move between a first position covering the current output interface 67 and a second position exposing it. When the cover plate 16 is in the second position, the current output interface 67 is exposed, and the user can then insert the starter clamp assembly 200 (see...) Figure 1 The plug is inserted into the current output interface 67, and the two start clips 210 and 220 of the start clip assembly 200 (see...) Figure 1 After being correctly connected to the positive and negative terminals (or metal body) of the car battery, the power supply unit 100 can output the instantaneous large current required to start the car starter motor.

[0054] Also refer to Figures 5 to 7In one embodiment, the first socket 61, the second socket 62, the circuit board 63, the two first female connectors 631, the two second female connectors 632, the power supply female connector 64, the NTC female connector 65, and the associated connecting wires are all located between one end of the battery module 20 at its length and the side wall 413 of the first end cover 12 of the first inner shell 41 facing the outer shell 10. As previously mentioned, the through hole 52 of the partition 50 is located near one end of the first inner shell 41, specifically near the side wall 413 of the first end cover 12 facing the outer shell 10. The advantage of this arrangement is that, since the first socket 61 and the second socket 62 are exposed through the through hole defined by the side wall 413 and the second inner shell 42, the first socket 61 and the second socket 62 need to be close to the side wall 413. The through hole 52 of the partition 50 is close to the side wall 413, so that the first female socket 631 and the second female socket 632 passing through the through hole 52 can be close to the side wall 413. In this way, the connecting wires of the first female socket 631 and the second female socket 632 on the connecting circuit board 43 and the first female socket 631 and the second female socket 632 on the circuit board module 30 have a shorter length, that is, the first socket 61 and the second socket 62 are electrically connected to the circuit board module 30 through a shorter connecting wire.

[0055] In one embodiment, the power supply device 100 can also function as a portable power source (also known as a power bank), capable of charging mobile electronic devices such as mobile phones, tablets, and laptops. (See reference) Figure 14 In this embodiment, the power supply device 100 further includes a retractable charging cable 71 (also known as a shell telescopic connecting cable 71), which is electrically connected to the circuit board module 30. The end of the retractable charging cable 71 is provided with a plug 711 (e.g., a USB-C plug), and one end of the first inner shell 41 (specifically, the side wall 413) is provided with a through hole 4131 through which the retractable connecting cable 71 passes (see...). Figure 10 and Figure 12 The outer casing 10 is also provided with a through hole for the retractable connecting cable 71 to pass through, specifically a through hole 17 provided on the first end cover 12 (see...). Figure 3 When not in use, the majority of the retractable charging cable 71 is located inside the outer casing 10 or the first inner casing 41, with only the plug 711 exposed. Figure 2 As shown. When needed, the user can pinch the plug 711 and pull the retractable charging cable 71 outward. The portion of the retractable charging cable 71 located inside the housing 10 or the first inner housing 41 is slowly pulled out until the exposed portion of the retractable charging cable 71 has reached the length required by the user or has reached its maximum exposed length.

[0056] With the above-described structure, when needed, the user can pull the retractable charging cable 71 outward to the desired length, thus facilitating connection to the mobile electronic device to be charged. After charging is complete, the user can remove the plug 711 from the mobile electronic device. After releasing the plug, the retractable charging cable 71 gradually retracts into the interior of the outer casing 10 or the first inner casing 41 until most of the retractable charging cable 71 is retracted into the interior of the outer casing 10 or the first inner casing 41.

[0057] The stretchability of the retractable charging cable 71 can be achieved in various ways. For example, in one embodiment, the retractable charging cable 71 is a cylindrical spiral spring cable. In another embodiment, refer to... Figure 13 and Figure 14 The power supply device 100 also includes a winding module 72 disposed in the first space 411 (see...). Figure 11 The retractable connecting cable 71 is retractably connected to the winding module 72. The winding module 72 includes a hollow body 73 and a winding reel 74 located inside the body 73. A central shaft 731 is provided inside the body 73, and the winding reel 74 is rotatably sleeved on the central shaft 731. A torsion spring (not shown) is provided between the winding reel 74 and the central shaft 731. One end of the retractable charging cable 71 is fixed to the winding reel 74 and the retractable charging cable 71 is wound around the winding reel 74. The other end of the retractable charging cable 71 (i.e., the plug 711) extends out from the opening 732 on the circumferential surface of the winding reel 74. The retractable charging cable 71 passes sequentially through the through hole 4131 of the first inner shell 41 (see...). Figure 10 and Figure 12 ) and the through hole 17 on the first end cap 12 of the outer casing 10 (see Figure 3 This process eventually exposes the plug 711. When the user pulls the retractable charging cable 71 outward, the outward movement of the retractable charging cable 71 causes the winding reel 74 to rotate in a first direction (e.g., clockwise), which in turn causes the torsion spring to twist. When the user releases the cable, the torque exerted by the torsion spring on the winding reel 74 causes the winding reel 74 to rotate in a second direction opposite to the first direction (e.g., counterclockwise), thereby causing the retractable charging cable 71 to gradually rewind around the winding reel 74, eventually causing most of the retractable charging cable 71 to retract into the interior of the outer casing 10 or the first inner casing 41.

[0058] refer to Figure 13 In one embodiment, the power supply device 100 further includes a magnet 75 disposed inside the housing 10. Specifically, the magnet 75 is disposed on the inner surface of the sidewall 413 of the first end cover 12 facing the first inner housing 41. For example, the inner surface of the first end cover 12 is provided with a plurality of interconnected protruding walls 121 (see...). Figure 17The magnet 75 is fixed within the receiving cavity formed by the plurality of protruding walls 121. When the plug 711 is positioned directly opposite the magnet 75 on the outer surface of the first end cap 12, the magnetic attraction of the magnet 75 holds the plug 711 in that position because the plug 711 includes a metal component that can be attracted by the magnet 75 (see [link to product description]). Figure 2 In this embodiment, the outer surface of the first end cap 12 is provided with a groove 122 for accommodating the plug 711 (see...). Figure 2 With the above structure, when not in use, the plug 711 can be stored in the groove 122 and remain stationary, which helps to protect the plug 711 and prevent it from being damaged by possible scratches.

[0059] In one implementation, reference Figure 11 , Figure 15 and Figure 16 The circuit board module 30 includes a first circuit board 32 and a second circuit board 33. The first circuit board 32 is electrically connected to the second circuit board 33. The distance between the first circuit board 32 and the partition 50 is greater than the distance between the second circuit board 33 and the partition 50. The winding module 72 is located above the second circuit board 33, and the winding module 72 and the first circuit board 32 are arranged side by side. In this case, the winding module 72 can be parallel to or overlap with the first circuit board 32, or it can be perpendicular to it. Understandably, in another embodiment, the retractable charging cable 71 can be located in the second space 412. In yet another embodiment, when the partition 50 is omitted, the first circuit board 32 and the second circuit board 33 can be replaced by a single circuit board. In this case, the retractable charging cable 71 can be located in any suitable position.

[0060] As shown in the figure Figure 6 and Figure 11 As shown, the winding module 72 and the connectors (i.e., the first socket 61 and the second socket 62) are at different heights relative to the second circuit board 33. Specifically, the winding module 72 and the connectors (i.e., the first socket 61 and the second socket 62) are located on opposite sides of the second circuit board 33.

[0061] In one embodiment, the retractable charging cable 71 is electrically connected to the first circuit board 32. Specifically, refer to... Figure 11 The winding module 72 includes a connecting plate 721 disposed within the body 73. A through hole is provided at the top of the body 73 away from the second circuit board 33 to expose the connecting plate 721. One end of the retractable charging cable 71 located inside the body 73 is electrically connected to the connecting plate 721. The exposed side of the connecting plate 721 is electrically connected to the first circuit board 32 via a connecting wire 722.

[0062] In one embodiment, the lower surface of the second circuit board 33 facing the bottom surface of the first space 411 is the aforementioned first surface 31 of the circuit board module 30. In one embodiment, a gap is formed between the lower surface of the second circuit board 33 and the bottom surface of the first space 411. This allows electronic components and / or pins located on the lower surface of the second circuit board 33 to remain in contact with the bottom surface of the first space 411, preventing potential impact from the bottom surface of the first space 411 on the electronic components and / or pins located on the lower surface of the second circuit board 33 due to accidental vibration, thereby preventing damage to the second circuit board 33 due to accidental vibration. (Reference) Figure 12 In one embodiment, the partition 50 is also provided with one or more clearance holes 53, which allow electronic components and / or pins on the lower surface of the second circuit board 33 to pass through. This contributes to the compactness of the overall structure.

[0063] In one embodiment, one or more positioning posts 4111 are provided on the bottom surface of the first space 411 (see...). Figure 12 The edge of the second circuit board 33 is provided with a corresponding number of positioning notches 331 (see...). Figure 11 The engagement of the aforementioned positioning post 4111 and positioning notch 331 enables the pre-positioning of the second circuit board 33, that is, to roughly position it at the desired location within the first space 411. The bottom surface of the first space 411 is also provided with a protrusion 4112 (see...). Figure 12 and Figure 13 The two ends of the second circuit board 33 abut against the end face of the first space 411 and the protrusion 4112, respectively, thereby preventing the second circuit board 33 from moving on the bottom surface of the first space 411.

[0064] In one embodiment, the winding module 72 is located on the top surface of the second circuit board 33 opposite to the first surface 31. The two can be in direct contact, or an insulating pad can be sandwiched between them. In either case, the winding module 72 applies pressure to the second circuit board 33 to prevent its movement. In another embodiment, the inner surface of the first space 411 is provided with a positioning structure, such as a slope or rib that contacts the outer peripheral surface of the winding module 72. This allows the winding module 72 to be roughly positioned in the desired location within the first space 411.

[0065] In one embodiment, the bottom surface of the first space 411 has multiple support pillars 4113 protruding at different positions, and the outer side of the support pillars 4113 has protruding ribs 4114. The first circuit board 32 is provided with multiple through holes 321 (see...). Figure 11The tops of the plurality of support pillars 4113 pass through the plurality of through holes 321 respectively. The bottom surface of the first circuit board 32 facing the bottom surface of the first space 411 is supported by the top of the protruding ribs 4114, thereby positioning the first circuit board 32 near the opening end of the first space 411. The tops of the plurality of support pillars 4113 are provided with threaded holes, which allow screws to be screwed in to fix the first circuit board 32.

[0066] refer to Figure 6 and Figure 11 In one embodiment, the power supply device 100 further includes an inner cover plate 76, which has a plurality of through holes 761. The top end of the positioning post 4111 has a threaded hole. Screws pass through the plurality of through holes 761 and are screwed into the threaded holes at the top ends of the positioning post 4111 and the support post 4113, thereby fixing the inner cover plate 76 to the positioning post 4111 and the support post 4113. The inner surface of the inner cover plate 76 contacts the top surface of the first circuit board 32 and the top surface of the winding module 72, respectively. Figure 4 and Figure 5 In the illustrated embodiment, the first circuit board 32 is held in place by two screws and by pressure applied by the inner cover plate 76. In one embodiment, the inner surface of the inner cover plate 76 is provided with a positioning structure, such as a protruding wall, which contacts the outer peripheral surface of the winding module 72. The winding module 72 is fixed in the first space 411 by the pressure of the inner surface of the inner cover plate 76 and the constraint of the protruding wall.

[0067] With the above configuration, the first circuit board 32 and the second circuit board 33 are positioned at different heights relative to the partition 50, and the first circuit board 32 and the second circuit board 33 overlap at most partially. This arrangement allows the space above the second circuit board 33 to be used to place the winding module 72, achieving full utilization of the space in the first space 411 and facilitating a compact structure.

[0068] refer to Figure 5 and Figure 6In one embodiment, the power supply device 100 further includes a display module 80 disposed on the side of the first circuit board 32 opposite to the second circuit board 33. The display module 80 is used to display information related to the operating status of the power supply device 100, such as prompts when the starter clamp assembly 200 is electrically connected to the power supply device 100, prompts when the starter clamp assembly 200 is correctly electrically connected to the vehicle battery, warnings when the starter clamp assembly 200 is incorrectly electrically connected to the vehicle battery, prompts when the power supply device 100 is charging, prompts when the power supply device 100 is charging other devices, high / low temperature warnings, etc. The body 11 of the housing 10 is provided with a through hole 18 corresponding to the display module 80 (see...). Figure 4 The through-hole 18 is covered by a light-transmitting panel 19 (see...). Figure 4 The coverage allows the information displayed by the display module 80 to be observed by the user. Figure 14 From this perspective, the battery module 20, separator 50, second circuit board 33, and first circuit board 32 are arranged sequentially at different heights from bottom to top. The top surface of the body 73 of the winding module 72 is slightly higher than the first circuit board 32, and the top surface of the inner cover 76 is approximately flush with the top surface of the display module 80. It is understood that the height relationship between the winding module 72 and the first circuit board 32, as well as the relationship between the top surface of the inner cover 76 and the top surface of the display module 80, is not limited to this and can be changed according to actual needs in other embodiments.

[0069] refer to Figure 1 , Figure 3 , Figure 5 and Figure 11 In one embodiment, the power supply device 100 further includes a lighting module 90, which includes a lighting circuit board 91 and a lampshade 92. The lighting circuit board 91 is disposed inside the housing 10. Specifically, one or more light-emitting elements (e.g., LED beads) are disposed on the lighting circuit board 91. The lighting circuit board 91 is fixed to the outer side of the first inner housing 41. Specifically, refer to... Figure 11 and Figure 12 The outer surface of the sidewall 414 of the first inner shell 41 has a receiving groove 4142 near the top. The lighting circuit board 91 is received precisely in the receiving groove 4142 near the opening of the first space 411 and is electrically connected to the first circuit board 32. In this embodiment, the lighting circuit board 91 is approximately perpendicular to the first circuit board 32. The lampshade 92 covers the lighting circuit board 91, and the side of the body 11 of the outer shell 10 has a through hole 111 that allows the lampshade 92 to be exposed (see...). Figure 3The lampshade 92 can be fixed to the body 11 by conventional connection methods, such as gluing or hot-melt bonding. The lighting circuit board 91 is electrically connected to the circuit board module 30, specifically to the first circuit board 32. When the ambient lighting is insufficient, the user can activate the lighting module 90, and the light-emitting element on the lighting circuit board 91 will emit light, thereby providing additional lighting for the user.

[0070] refer to Figure 1 , Figures 18 to 20 In one embodiment, a starting power supply assembly includes a starting power supply (i.e., the aforementioned power supply device 100) and a starting clamp assembly 200. The starting clamp assembly 200 is detachably electrically connected to the starting power supply and the positive and negative terminals (or metal body) of the vehicle's battery, thereby allowing the starting power supply to output the instantaneous high current required to start the vehicle's starter motor.

[0071] In one embodiment, the starter clamp assembly 200 includes a housing 230, a connection interface 240, a positive wire 251 and a negative wire 252, an on / off control element 260, an adapter 270, and a control circuit board 280. The connection interface 240 is exposed on the outer surface of the housing 230 and is used to mate with the current output interface 67 of the starter power supply to establish an electrical connection between the starter power supply and the starter clamp assembly 200. The positive wire 251 and the negative wire 252 pass through one side of the housing 230 into the housing 230 and exit from the other side of the housing 230. One end of the positive wire 251 and one end of the negative wire 252 are connected to the connection interface 240, and the other ends of the positive wire 251 and the negative wire 252 are respectively connected to two starter clamps 210 and 220. The on / off control element 260, the adapter 270 and the control circuit board 280 are all located inside the housing 230. The positive wire 251 or the negative wire 252 is electrically connected to the adapter 270, and the control circuit board 280 is electrically connected to the on / off control element 260 through the adapter 270.

[0072] The on / off control element 260 includes a first normally open connection point and a second normally open connection point. In one embodiment, the on / off control element 260 is a relay. In this case, the first normally open connection point and the second normally open connection point are the first normally open contact and the second normally open contact of the relay. The on / off control element 260 can be controlled to switch between two states: electrically on and electrically off. This allows the circuit containing the on / off control element 260 to switch between two states: closed and open. In another embodiment, the on / off control element 260 is not limited to a relay. It can be a transistor (e.g., a bipolar junction transistor, a metal-oxide-semiconductor field-effect transistor). The first normally open connection point and the second normally open connection point are the collector and emitter of the bipolar junction transistor or the drain and source of the metal-oxide-semiconductor field-effect transistor. This transistor can also be controlled to switch between two states: electrically on and electrically off. This allows the circuit containing the on / off control element 260 to switch between two states: closed and open. The following description uses a relay as an example to illustrate the on / off control element 260. However, those skilled in the art will recognize that the technical solutions discussed below can also use transistors as on / off control elements as needed.

[0073] The relay 260 is disposed inside the housing 230, and the relay 260 includes a first normally open contact (not shown) and a second normally open contact (not shown). The adapter 270 is disposed inside the housing 230, and the adapter 270 is electrically connected to the first and second normally open contacts. The positive wire 251 or the negative wire 252 is electrically connected to the first and second normally open contacts through the adapter 270.

[0074] With the above-described configuration, the positive wire 251 or negative wire 252 is normally open. After the starting clamps 210 and 220 are correctly connected to the positive and negative terminals (or metal body) of the vehicle battery, the relay 260 is activated. This causes the movable contact to be attracted by electromagnetic force, connecting it to the fixed contact. This connects the first and second normally open contacts, thereby switching the positive wire 251 or negative wire 252 from an electrically open state to an electrically connected state. Thus, the starting power supply can establish an electrical connection with the positive and negative terminals (or metal body) of the vehicle battery, allowing it to output the instantaneous high current required to start the vehicle's starter motor. By using the adapter 270 to electrically connect the positive wire 251 or the negative wire 252 to the first normally open contact and the second normally open contact of the relay 260, the large volume of the housing 230 is avoided when the positive wire 251 or the negative wire 252 is directly electrically connected to the first normally open contact and the second normally open contact of the relay 260, which is beneficial to the compactness of the starter clamp assembly 200.

[0075] In one embodiment, the housing 230 is generally cuboid in shape and includes a body 231 and a bottom cover 232 connected to each other, which together define a receiving space for accommodating the connection interface 240, the relay 260, the adapter 270, and other components.

[0076] The connection interface 240 is a plug connector that protrudes from one side of the body 231. The connection interface 240 can be inserted into the current output interface 67 of the starting power supply to establish an electrical connection with it. Understandably, in another embodiment, the connection interface 240 can be a socket connector, in which case a connecting cable with plugs at both ends can be used to electrically connect the connection interface 240 to the current output interface 67. Understandably, in another embodiment, the connection interface 240 can be omitted, in which case one end of the positive wire 251 and one end of the negative wire 252 are directly and non-detachably connected to the starting power supply.

[0077] In one embodiment, the adapter 270 is an adapter circuit board, including a first connection point and a second connection point. The first connection point is electrically connected to the first normally open contact, and the second connection point is electrically connected to the second normally open contact. The negative wire 252 includes a first segment 2521 and a second segment 2522. One end of the first segment 2521 is electrically connected to the first normally open contact via the adapter 270, and the other end is electrically connected to the starter clip 220. One end of the second segment 2522 is electrically connected to the second normally open contact via the adapter 270, and the other end is electrically connected to the connection interface 240. With this configuration, in the normal state, i.e., when the relay 260 is not controlled to engage, the negative wire 252 is electrically disconnected. Understandably, in another embodiment, the positive wire 251 can be connected to the first and second normally open contacts of the relay 260 in the same manner as described above.

[0078] refer to Figure 18In one embodiment, the control circuit board 280 is fixed inside the body 231 of the housing 230. The control circuit board 280 is electrically connected to the relay 260 via the adapter 270. Specifically, the microcontroller on the control circuit board 280 is electrically connected to the coil control terminal of the relay 260. When the starter clips 210 and 220 are detected to be correctly connected to the positive and negative terminals of the vehicle battery (or the metal body), the microcontroller can output a trigger signal (e.g., 12V voltage) to the coil control terminal. A current is generated in the coil inside the relay 260. This current generates a magnetic field around the iron core inside the relay 260. This magnetic field causes the moving contact to be attracted and move to a position where it connects with the fixed contact, ultimately causing the first normally open contact and the second normally open contact of the relay 260 to connect. It should be noted that the adapter 270 can be electrically connected to the control circuit board 280 by soldering, wires, or other suitable means. Similarly, the relay 260 can be electrically connected to the adapter 270 by soldering, wires, or other suitable means.

[0079] In one embodiment, the control circuit board 280 and the adapter 270 are located on different sides of the relay 260, respectively. Figure 18 From the view shown, the control circuit board 280 faces the top surface of the relay 260, and the adapter 270 faces the front side of the relay 260. Thus, in this embodiment, the control circuit board 280 and the adapter 270 are perpendicular to each other. It is understood that the arrangement of the control circuit board 280 and the adapter 270 is not limited to this; other suitable arrangements can be adopted in other embodiments as needed. For example, the control circuit board 280 and the adapter 270 can be arranged parallel to each other.

[0080] In one embodiment, the adapter 270 is inserted into a mounting slot 2801 on the control circuit board 280. Figure 18 From the view shown, the adapter 270 generally fits against one side of the relay 260. The adapter 270 includes an ear 271 extending beyond one edge of the relay 260. One end of the first segment 2521 of the negative wire 252 is connected to the ear 271 facing outwards. Figure 18 On the surface in the negative Y-axis direction, one end of the second segment 2522 of the negative conductor 252 is connected to the side of the adapter 270 opposite to one end of the first segment 2521. With this configuration, one end of the first segment 2521 and one end of the second segment 2522 of the negative conductor 252 are respectively connected to opposite sides of the adapter 270. Compared to directly connecting one end of the first segment 2521 and one end of the second segment 2522 to the first and second normally open contacts of the relay 260, the aforementioned configuration does not involve connection in the height direction (i.e.,...). Figure 18The direction indicated by the Y-axis leads to an increase in size, thus eliminating the need to increase the height of the housing 230 to provide sufficient space, allowing the housing 230 to have a satisfactory height. Therefore, in this embodiment, the maximum height of the housing 230 is less than the maximum height of the starting power supply 100 electrically connected to the starter clamp assembly 200. Both the maximum height of the housing 230 and the maximum height of the starting power supply 100 are along the Y-axis direction. Figure 1 The Z-axis direction measurement is shown. Furthermore, considering that the control circuit board 280 is along... Figure 18 The z-axis is positioned above the relay 260 and is connected via an adapter 270. To accommodate high current, the large-diameter positive and negative wires do not need to be directly connected to the control circuit board 280, which helps reduce the length of the housing 230 along the z-axis. Figure 18 The height in the z-axis direction.

[0081] The arrangement of the relay 260, adapter 270, and control circuit board 280 is not limited to the aforementioned configuration. In another embodiment, the relay 260 and control circuit board 280 are located on the same side of the adapter 270. The relay 260 is electrically connected to the adapter 270 by soldering or other suitable means. The relay 260 and control circuit board 280 are arranged side by side, with the control circuit board 280 approximately parallel to the adapter 270. In this embodiment, the positive wire 251, the negative wire 252, and the connection interface 240 are located on the side of the adapter 270 opposite to the relay 260.

[0082] In one embodiment, the starter clamp assembly 200 further includes a display module 291 disposed on the side of the control circuit board 280 opposite to the relay 260. The display module 291 is used to display prompts, such as prompts indicating that the starter clamp assembly 200 is electrically connected to the power supply device 100, prompts indicating that the starter clamp assembly 200 is correctly electrically connected to the vehicle battery, and warnings indicating that the starter clamp assembly 200 is incorrectly electrically connected to the vehicle battery. The display module 291 can be a conventional display module, such as an LCD display module.

[0083] To save costs, in one embodiment, the display module 291 includes multiple sets of light-emitting elements (e.g., light emitters) disposed on the control circuit board 280. Figure 18The housing 230 comprises a first group of light-emitting elements 292a, a second group of light-emitting elements 292b, a third group of light-emitting elements 292c, and a light-transmitting film 293. The main body 231 of the housing 230 has through holes 233 facing the multiple groups of light-emitting elements, and the light-transmitting film 293 covers these through holes 233. Corresponding to each group of light-emitting elements, the light-transmitting film 293 displays corresponding prompt text, such as "start," "error," or "empower." Only the area of ​​the light-transmitting film 293 displaying these prompt texts is translucent; the remaining areas are opaque. Thus, under normal conditions, the prompt text is in a "dark" state. When a group of light-emitting elements emits light, the corresponding prompt text changes from "dark" to "illuminated," thereby alerting the user.

[0084] In one embodiment, after the connection interface 240 establishes an electrical connection with the current output interface 67, the control circuit board 280 controls a set of light-emitting elements corresponding to the prompt text "start" to flash, thereby causing "start" to light up and flash. Furthermore, after the connection interface 240 establishes an electrical connection with the current output interface 67 and the two starter clips 210 and 220 are correctly connected to the positive and negative terminals of the car battery (or the metal body), the control circuit board 280 controls the set of light-emitting elements corresponding to the prompt text "start" to light up, keeping "start" constantly lit.

[0085] In one implementation, if the two starter clips 210 and 220 are incorrectly connected to the positive and negative terminals (or metal body) of the car battery (e.g., starter clip 210 is connected to the negative terminal and starter clip 220 is connected to the positive terminal), the control circuit board 280 controls a set of light-emitting elements corresponding to the above-mentioned error message to keep the error constantly lit.

[0086] In one embodiment, after the connection interface 240 establishes an electrical connection with the current output interface 67 and the two starter clips 210 and 220 are correctly connected to the positive and negative terminals (or metal body) of the car battery, the control circuit board 280 determines that the voltage of the car battery is lower than a preset value (e.g., 4V). It then controls a set of light-emitting elements corresponding to the aforementioned prompt text "empower" to illuminate, keeping "empower" constantly lit to prompt the user to enter the forced start mode. For this purpose, the control circuit board 280 is also equipped with a switch 281. Corresponding to the switch 281, the starter clip assembly 200 also includes a button 234 slidably connected to the body 231 of the housing 230. After the user observes that "empower" is constantly lit, the user can press the button 234, which triggers the switch 281. Upon detecting that the switch 281 has been triggered, the control circuit board 280 controls a set of light-emitting elements corresponding to the aforementioned prompt text "start" to illuminate, keeping "start" constantly lit.

[0087] The previous section discussed two scenarios where the starter is constantly lit. Regardless of the scenario, once the user observes that the starter is constantly lit, the user can press the starter switch on the starter power supply, thereby enabling the starter power supply to output the instantaneous high current required to start the car starter motor.

[0088] In one embodiment, the connection interface 240 includes a communication terminal 241 for communicating with the power supply 100 (see...). Figure 21 In this embodiment, the connection interface 240 includes a positive terminal 242 and a negative terminal 243. In this embodiment, a communication terminal 241 is located between the positive terminal 242 and the negative terminal 243, and both the communication terminal 241 and the positive terminal 242 are electrically connected to the positive wire 251. In one embodiment, the communication terminal 241 and the positive terminal 242 can be integrally formed and fixed in the same insulating part. It is understood that in another embodiment, the communication terminal 241 and the negative terminal 243 are integrally formed and fixed in the same insulating part. In one embodiment, the power supply 100 can determine the relevant information of the vehicle battery by reading the voltage of the communication terminal 241, and then display the relevant information of the vehicle battery through the display module 80 of the power supply 100.

[0089] refer to Figure 18 In one embodiment, the housing 230 also includes a light-transmitting decorative cover 235 attached to the top of its body 231. The light-transmitting decorative cover 235 covers the top of the body 231 but allows the luminous prompt text of the light-transmitting film 293 to be observed by the user.

[0090] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
