[0067] As shown in Figures 1, 2, and 3, an embodiment of the present application provides an emergency starting power supply 100 for automobiles. The emergency starting power supply 100 for automobiles primarily functions as an emergency power supply for starting an automobile when the automobile cannot be started due to a lack of electricity or other reasons. The emergency starting power supply 100 for automobiles comprises a case 110, a power supply 120, a circuit board 130, and an output terminal 140.

[0068] Referring to Figure 4, the case 110 includes a first housing space 111 and a first mounting portion 112, the power supply 120 and the circuit board 130 housed in the first housing space 111, the power supply 120 is electrically connected to the circuit board 130 and the output terminal 140 respectively, the first mounting portion 112 has a second housing space 1121, at least a portion of the output terminal 140 is housed in the second housing space 1121, and the output terminal 140 is configured to output a current for starting an automobile engine.

[0069] The automobile emergency starting power supply 100 according to the embodiment of this application can achieve the emergency starting function of the automobile emergency starting power supply 100 by electrically connecting the power supply 120 and the output terminal 140, which allows the output terminal 140 to output a current to start an automobile engine. By electrically connecting the power supply 120 and the circuit board 130, the circuit board 130 can output the current required for other electrical devices (e.g., mobile phones).

[0070] By housing the power supply 120 and the circuit board 130 in the first housing space 111 of the case 110, the power supply 120 and the circuit board 130 are stably mounted in the first housing space 111 of the case 110, improving the mounting stability and reliability of the power supply 120 and the circuit board 130. Furthermore, by housing at least a portion of the output terminals 140 in the second housing space 1121 of the first mounting portion 112 of the case 110, the output terminals 140 are stably mounted in the second housing space 1121 of the first mounting portion 112 of the case 110, improving the mounting stability and reliability of the output terminals 140, thereby extending the service life of the automotive emergency starting power supply 100.

[0071] As shown in Figures 1, 2, and 4, in one embodiment of the present application, the first mounting portion 112 optionally has at least one first projection 1122 configured to restrict the position of the circuit board 130. In this way, the mounting efficiency, stability, and reliability of the circuit board 130 can be improved by restricting the displacement of the circuit board 130 in a first direction by the first projection 1122. Exemplarily, the first mounting portion 112 can support the circuit board 130 in a second direction, thereby creating a gap between the circuit board 130 and the output terminals 140, which can prevent damage to the circuit board 130 due to interference between the two.

[0072] The first direction is the longitudinal direction of case 110, which is the X direction in Figure 1, and the second direction is the thickness direction of case 110, which is the Z direction in Figure 1.

[0073] As shown in Figures 1, 2, and 4, in one embodiment of this application, the first mounting portion 112 optionally has at least one first opening 1123, the first opening 1123 is configured to accommodate a cable connected to the output terminal 140. By providing the first opening 1123 in the first mounting portion 112 in this way, the first opening 1123 acts as a clearance, thereby contributing to the electrical connection between one end of the cable and the power supply 120, and the other end of the cable passing through the first opening 1123 to connect to the output terminal 140, thereby achieving an electrical connection between the output terminal 140 and the power supply 120.

[0074] As shown in Figures 1, 2, and 4, in the above embodiment of this application, a second opening 1124 is optionally provided below the first opening 1123. In this embodiment, the first mounting portion 112 is injection molded by a mold, and the strength of the mold is increased by providing the second opening 1124 located below the first opening 1123 in the first mounting portion 112.

[0075] As shown in Figures 1, 2, 3, and 4, in one embodiment of the present application, the case 110 optionally includes a first case 1101 and a second case 1102, the first case 1101 having a first mounting portion 112, and the second case 1102 having a second projection 11021, the second projection 11021 being configured to restrict the position of the output terminal 140. In this embodiment, by providing the second projection 11021 on the second case 1102, when the second case 1102 and the first case 1101 are assembled together, the second projection 11021 can contact the output terminal 140, thereby restricting the output terminal 140 to the second housing space 1121 of the first mounting portion 112, preventing the output terminal 140 from moving or coming out of the second housing space 1121, thereby improving the mounting stability and reliability of the output terminal 140 and extending the service life of the product.

[0076] As shown in Figure 15, in one embodiment of this application, a first cover 150 is optionally further provided, the first cover 150 being fixedly connected to the first mounting portion 112 and configured to restrict the position of the output terminal 140. In this embodiment, by installing the first cover 150 fixedly connected to the first mounting portion 112, the output terminal 140 is restricted to the second housing space 1121 of the first mounting portion 112, preventing the output terminal 140 from moving or coming out of the second housing space 1121, thereby improving the mounting stability and reliability of the output terminal 140 and extending the service life of the product.

[0077] As shown in Figures 1, 2, and 4, in one embodiment of this application, the output terminal 140 is optionally installed between the first mounting portion 112 and the circuit board 130. In this embodiment, by installing the output terminal 140 between the first mounting portion 112 and the circuit board 130, the first housing space 111 can be used rationally and the structural layout can be made compact.

[0078] As shown in Figures 1, 2, 3, and 4, in the above embodiment of this application, optionally, a portion of the circuit board 130 is configured to cover a portion of the first mounting portion 112. In this way, the second projection 11021 can contact the output terminal 140 without interfering with the circuit board.

[0079] As shown in Figures 1, 2, and 4, in one embodiment of this application, the circuit board 130, the first mounting portion 112, and the output terminal 140 are optionally installed on the same side relative to the power supply 120.

[0080] As shown in Figures 1, 2, and 4, in one embodiment of this application, the output terminal 140 optionally has a first coupling portion 141, and the first mounting portion 112 has a second coupling portion 1125, and the first coupling portion 141 and the second coupling portion 1125 are detachably connected. In this way, the output terminal 140 can be detachably connected to the second coupling portion 1125 of the first mounting portion 112 by the first coupling portion 141, and the efficiency of attaching and detaching the output terminal 140 can be increased.

[0081] As shown in Figures 1, 2, and 4, in the above embodiment of this application, the first coupling portion 141 and the second coupling portion 1125 are optionally slidably connected. This facilitates the attachment and detachment of the output terminal 140 and the first mounting portion 112, improving the smoothness of attachment and detachment.

[0082] As shown in Figures 1, 2, and 4, in the above embodiment of this application, optionally, the first connecting portion 141 is a third projection 1411 and the second connecting portion 1125 is a housing groove 11251, and when installed, the first connecting portion 141 slides through the second connecting portion 1125 to a predetermined position. In this way, the slidable connection between the third projection 1411 and the housing groove 11251 can effectively improve the smoothness of installation and removal.

[0083] As shown in Figures 1, 2, and 4, in the above embodiment of this application, the first coupling portion 141 is optionally installed on the outer edge of the end of the output terminal 140 facing the first housing space 111, thereby contributing to inserting the first coupling portion 141 into the second coupling portion 1125 by pushing when installing, or contributing to pulling out the first coupling portion 141 from the second coupling portion 1125 when removing, thereby improving the efficiency of installation and removal.

[0084] As shown in Figures 12, 13, and 14, in the above embodiment of this application, the first mounting portion 112 optionally has a first through hole 1126, one end of the output terminal 140 is passed through the first through hole 1126, and the first coupling portion 141 is installed on the end of the output terminal 140 that is not passed through the first through hole 1126. This makes it possible to attach the output terminal 140 to the first mounting portion 112.

[0085] As shown in Figures 12, 13, and 14, in the above embodiment of this application, the first coupling portion 141 and the second coupling portion 1125 are optionally connected by screws. In this way, the mounting stability and reliability of the output terminal 140 and the first mounting portion 112 can be improved, and the output terminal 140 can be removed from the first mounting portion 112, which contributes to maintenance and replacement.

[0086] As shown in Figures 12, 13, and 14, in the above embodiment of this application, the screw head is optionally placed in the second housing space 1121, that is, at the outward end of the first case 1101, thereby contributing to the tightening and loosening of the screw by a screwdriver.

[0087] As shown in Figure 1, in one embodiment of this application, the case 110 optionally includes a first case 1101 and a second case 1102, the first case 1101 having a first mounting portion 112, and the second case 1102 having a button 11022.
