[0049] Referring to Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides a power module 100, comprising: a shell 1, a middle frame assembly 2 and a power supply 3. The shell 1 comprises a receiving cavity 11 with an opening, and the power supply 3 is arranged in the receiving cavity 11. The middle frame assembly 2 is arranged in the receiving cavity 11, and the middle frame assembly 2 can be used to fix the power supply 3.

[0050] In the embodiment, at least one groove 12 is arranged on the inner wall of the shell 1, and at least one sliding part 21 is arranged on the outer periphery of the middle frame assembly 2 corresponding to the groove 12, and the sliding part 21 is configured to be at least partially located in the groove 12 and can slide relative to the groove 12. Through the arrangement of the groove 12 on the inner wall of the shell 1 and the sliding part 21 on the middle frame assembly 2, the guiding and positioning can be provided during the assembly of the middle frame assembly 2 and the shell 1, the matching position between the two can be quickly found, and the assembly efficiency between the middle frame assembly 2 and the shell 1 in the power module 100 can be improved.

[0051] Meanwhile, at least one first fixing part 13 is arranged on the inner wall of the shell 1, and at least one second fixing part 22 is arranged on the middle frame assembly 2 corresponding to the first fixing part 13. When the middle frame assembly 2 slides to the position where the first fixing part 13 and the second fixing part 22 interfere with each other, the middle frame assembly 2 is fixed in the receiving cavity 11. When the sliding part 21 on the middle frame assembly 2 slides along the guide provided by the groove 12 to the position where the first fixing part 13 and the second fixing part 22 interfere with each other, the middle frame assembly 2 can be fixed in the receiving cavity 11 of the shell 1. Through the arrangement of the first fixing part 13 and the second fixing part 22, the middle frame assembly 2 can be kept in the receiving cavity 11 after being assembled relative to the shell 1.

[0052] In some embodiments, the first fixing part 13 and the second fixing part 22 can be components connected and matched with each other through clamping, magnetic attraction, interference fit, threaded connection and the like. Exemplarily, the first fixing part 13 can be one of a buckle and a clamping groove, and the second fixing part 22 can be the other one of the buckle and the clamping groove. Alternatively, the first fixing part 13 and the second fixing part 22 can both be magnetic attraction members.

[0053] In some embodiments, referring to Figures 3 to 10The middle frame assembly 2 is provided with at least one cantilever 23, and the second fixing member 22 is arranged on the cantilever 23. The cantilever 23 can make the middle frame assembly 2 elastically deform when sliding relative to the inner wall of the shell 1, so that the friction between the middle frame assembly 2 and the inner wall of the shell 1 is smaller, and the sliding is smoother. Exemplarily, the second fixing member 22 can be a buckle, and the first fixing member 13 can be a clamping groove corresponding to the buckle. The buckle arranged on the cantilever 23 can reduce the friction with the inner wall of the shell 1 when the middle frame assembly 2 slides in the shell 1, so that the cantilever 23 can smoothly slide to the clamping groove.

[0054] In some embodiments, referring to Figure 3 The cantilever 23 includes a fixed end 231 and a free end 232, and the free end 232 can be provided with an inclined surface 233. The inclined surface 233 can play a guiding role, and can reduce the friction between the cantilever 23 and the inner wall of the shell 1 when the cantilever 23 moves relative to the inner wall of the shell 1, so that the middle frame assembly 2 slides relative to the shell more smoothly and has smaller resistance.

[0055] In some embodiments, referring to Figure 4 and Figure 5 The groove 12 can include a first convex rib 14 and a second convex rib 15 extending along the length direction of the shell 1, and the first convex rib 14 and the second convex rib 15 are arranged at intervals. The first convex rib 14 and the second convex rib 15 can jointly define the groove 12.

[0056] In some embodiments, referring to Figure 3 , Figure 4 and Figure 5 The extension lengths of the first convex rib 14 and the second convex rib 15 along the length direction of the shell 1 can be different. Through the different lengths of the first convex rib 14 and the second convex rib 15, the insertion direction of the middle frame assembly can be quickly adjusted according to the different lengths of the first convex rib 14 and the second convex rib 15 during the assembly of the middle frame assembly 2 and the shell 1, so as to improve the assembly efficiency. In addition, the longer first convex rib 14 can provide guidance for sliding, so that the sliding part 21 can be more easily slid into the groove 12, for example, the sliding part 21 can be close to the end of the accommodating cavity 11 along the first convex rib 14, and slowly slide into the groove 12 by abutting against the first convex rib 14, so as to avoid the mispositioning of the sliding part 21 and the groove 12.

[0057] In some embodiments, referring to Figure 3 , Figure 4 and Figure 5The first protruding rib 14 and / or the second protruding rib 15 can be provided with a first guide surface 15141 near the opening end of the accommodating cavity 11, which is used to guide the sliding part 21 into the groove 12. For example, the first protruding rib 14 and the second protruding rib 15 can be provided with a first guide surface 15141 near the opening end of the accommodating cavity 11, which can guide the sliding part 21 and make it easier to slide into the groove 12. Alternatively, only the first protruding rib 14 or the second protruding rib 15 can be provided with a first guide surface 15141 near the opening end of the accommodating cavity 11, which can also guide the sliding part 21 and make it easier to slide into the groove 12.

[0058] In other embodiments, referring to Figure 3 、 Figure 8 and Figure 9 , the sliding part 21 is arranged on the opposite ends of the middle frame assembly 2 away from the cantilever 23. For example, the groove 12 on the inner wall of the shell 1 is arranged on the inner wall of the shell 1 away from the opening of the shell 1; correspondingly, the sliding part 21 on the middle frame assembly 2 is arranged on the end of the middle frame assembly 2 away from the opening of the shell 1, so that the sliding part 21 and the groove 12 can be easily matched. The cantilever 23 is arranged on the other end of the middle frame assembly 2 corresponding to the sliding arm, and when the sliding part 21 slides relative to the groove 12 to the bottom of the accommodating cavity 11, the buckle on the cantilever 23 can be matched with the clamping groove on the shell 1.

[0059] In some embodiments, referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9 , two grooves 12 can be arranged on the inner wall of the shell, and the sliding part 21 includes two extension parts 211 arranged on the end of the middle frame assembly 2 away from the cantilever 23, and the positions of the two extension parts 211 correspond to the two grooves 12. For example, the two grooves 12 on the inner wall of the shell are symmetrically arranged on the same half of the shell, so that when the middle frame assembly 2 is assembled, the installation direction of the middle frame assembly 2 can be quickly determined according to the positions of the two grooves 12. Further, the end of the extension part 211 away from the cantilever 23 is provided with a fourth guide surface 2111, which can reduce the frictional resistance between the extension part 211 and the groove 12, and make the relative sliding between the extension part 211 and the groove 12 more smooth.

[0060] In some embodiments, referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 andFigure 9 The outer periphery of the middle frame assembly 2 away from one end of the extension 211 can be provided with two cantilever arms 23, and each cantilever arm 23 is provided with a second fixing member 22. The inner wall of the shell 1 is provided with two first fixing members 13 corresponding to the two second fixing members 22. Illustratively, the outer periphery of the middle frame assembly 2 away from one end of the extension 211 is provided with two cantilever arms 23, and each cantilever arm 23 can be provided with a buckle. The inner wall of the shell 1 is provided with two clamping grooves corresponding to the two buckles. When the middle frame assembly 2 is assembled into the accommodating cavity 11 of the shell 1, the buckles on the two cantilever arms 23 are abutted by the clamping grooves, which can make the cantilever arms 23 slightly deform in the direction away from the inner wall of the shell 1, thereby reducing the friction between the inner wall of the shell 1 and the buckles on the cantilever arms 23, so that the buckles can more smoothly slide into the accommodating cavity 11 along the cantilever arms 23 and be clamped with the clamping grooves on the inner wall of the shell 1. When the buckles slide to the clamping grooves, the abutting force exerted by the inner wall of the shell 1 on the cantilever arms 23 can be released, and the cantilever arms 23 return to their original state, so that the buckles on the cantilever arms 23 can be clamped with the clamping grooves on the shell 1, preventing the middle frame assembly 2 from loosening or being separated from the accommodating cavity 11.

[0061] In other embodiments, referring to Figure 6 , Figure 7 and Figure 10 , the sliding part 21 is arranged at one end of the middle frame assembly 2 having the cantilever arm 23, and the sliding part 21 can be connected with the second fixing member 22. Illustratively, the groove 12 on the inner wall of the shell 1 is arranged at a position close to the opening of the accommodating cavity 11. The groove 12 can be a groove formed by recessing the inner wall of the shell 1. The sliding part 21 on the middle frame assembly 2 is arranged at one end of the cantilever arm 23 corresponding to the groove 12. When the middle frame assembly 2 is assembled into the shell 1, the sliding part 21 can be aligned with the groove 12 on the inner wall of the shell 1 and slide along the groove 12 to the inside of the accommodating cavity 11 under the pushing of an external force.

[0062] Further, one end of the sliding part 21 close to the free end 232 of the cantilever arm 23 can be provided with a second guide surface 212. The presence of the second guide surface 212 can reduce the frictional resistance between the sliding part 21 and the groove 12, making the relative sliding between the sliding part 21 and the groove 12 more smooth.

[0063] Further, one end of the second fixing member 22 close to the free end 232 of the cantilever arm 23 is provided with a third guide surface 221. Illustratively, the second fixing member 22 can be a buckle. The presence of the third guide surface 221 on the buckle can reduce the frictional resistance between the buckle and the inner wall of the shell 1, thereby making the assembly between the middle frame assembly 2 and the shell 1 more smooth.

[0064] In some embodiments, referring to Figure 6 , Figure 7 and Figure 10The two sides of the outer periphery of the middle frame assembly 2 are provided with two cantilever arms 23, and each cantilever arm 23 is provided with a second fixing part 22. The inner wall of the shell 1 is provided with two first fixing parts 13 corresponding to the two second fixing parts 22. The middle frame assembly 2 is provided with at least one sliding part 21, and one sliding part 21 is connected with one second fixing part 22 and is arranged in a perpendicular extension manner. For example, the second fixing part 22 can be a buckle, the first fixing part 13 can be a card slot matched with the buckle, the sliding part 21 can be arranged on the cantilever arm 23 of the middle frame assembly 2, and the sliding part 21 can be connected with the buckle on the cantilever arm 23 and be perpendicular to the buckle. The sliding part 21 and the buckle can form a “cross” structure. Specifically, the extension direction of the sliding part 21 is the same as the extension direction of the groove 12, and the extension direction of the buckle is perpendicular to the extension direction of the groove 12.

[0065] In some embodiments, referring to FIGS. Figure 6 , Figure 7 and Figure 10 , the inner wall of the shell 1 is provided with a groove 12 corresponding to the sliding part 21. The groove 12 extends from the opening of the accommodating cavity 11 to the first fixing part 13. For example, the groove 12 can extend from the opening of the accommodating cavity 11 to the card slot. When the middle frame assembly 2 is assembled with the shell 1, the free end 232 of the cantilever arm 23 is abutted by the inner wall of the shell 1 and is deformed away from the inner wall. One end of the sliding part 21 close to the fixed end 231 of the cantilever arm 23 can be at least partially located in the groove 12 and can slide along the groove 12 to the bottom of the accommodating cavity 11 under the pushing of an external force. When the buckle on the cantilever arm 23 slides to match with the card slot provided on the inner wall of the shell 1, the middle frame assembly 2 is fixedly connected with the shell 1. In some embodiments, the sliding part 21 can be arranged on only one cantilever arm 23, and only one sliding groove corresponding to the sliding part 21 can be arranged on the inner wall of the shell 1. In other embodiments, the sliding part 21 can be arranged on both cantilever arms 23, and two grooves 12 corresponding to the two sliding parts 21 can be arranged on the inner wall of the shell 1.

[0066] In some embodiments, referring to Figures 2 to 10The open end of the shell 1 can be provided with at least one positioning groove 16 corresponding to the position of the first fixing member 13, and the second fixing member 22 is configured to be inserted into the accommodating cavity 11 from the positioning groove 16 and matched with the first fixing member 13. Exemplarily, the first fixing member 13 can be a clamping groove, and the second fixing member 22 can be a buckle corresponding to the clamping groove. In order to make the buckle on the middle frame assembly 2 better match the groove 12 on the inner wall of the shell 1, two positioning grooves 16 can be provided on the opposite sides of the open end of the shell 1, so that when the middle frame assembly 2 is assembled, the two cantilever arms 23 on the middle frame assembly 2 can be aligned with the two positioning grooves 16 and then inserted into the accommodating cavity 11 of the shell 1. At this time, the sliding part 21 on the middle frame assembly 2 is just aligned with the groove 12 on the inner wall of the shell 1, and under the pushing of external force, the sliding part 21 on the middle frame assembly 2 can slide along the groove 12 to the inside of the accommodating cavity 11 until the buckle matches the clamping groove. Through the setting of the positioning groove 16, the assembly personnel can quickly find the assembly position between the middle frame assembly 2 and the shell 1, and the assembly efficiency is improved.

[0067] Further, referring to Figure 2 and Figure 7 , the shell 1 can also be provided with a charging opening 17, and the external power supply 3 can charge the power supply module 100 through the charging opening 17. In addition, the charging opening 17 can be provided together with the positioning groove 16 to provide the assembly direction for the assembly personnel when the middle frame assembly 2 and the shell 1 are assembled, so that the assembly efficiency is higher. Exemplarily, the two positioning grooves 16 on the shell 1 can be provided on the left and right sides of the open end of the shell 1, and the charging opening 17 can be provided on the front side of the shell 1.

[0068] In some embodiments, referring to Figure 8 , Figure 9 , Figure 10 and Figure 11 , the middle frame assembly 2 includes a body part 24 and a wall part 25. The body part 24 can be configured as a cover body, and the wall part 25 can extend from the body part 24 along the length direction of the shell 1. The body part 24 is provided with an airflow sensor 5 and a circuit board 6, and is used to fix the airflow sensor 5 and the circuit board 6. Exemplarily, the body part 24 can be provided with a recess cavity 241 for accommodating the airflow sensor 5. The circuit board 6 can be provided on one side of the opening of the recess cavity 241, and can be fixed to the body part 24 by a fastener 7. The circuit board 6 can support the airflow sensor 5 and block the opening of the recess cavity 241.

[0069] In some embodiments, referring to Figure 8 , Figure 9 and Figure 10The wall 25 of the middle frame assembly 2 can be arc-shaped, and the wall 25 can be used to support the power supply 3 accommodated in the accommodation cavity 11. The middle frame assembly 2 can further be provided with a fixing band 4, and the fixing band 4 can wind the power supply 3 on the wall 25, so as to fix the power supply 3 on the wall 25.

[0070] In some embodiments, referring to Figure 10 The sliding part 21 can be arranged on the outer periphery of the body part 24. For example, the outer periphery of the body part 24 is provided with two cantilever arms 23 on both sides, and the outer side of the cantilever arm 23 is provided with a buckle. The sliding part 21 is arranged on the cantilever arm 23 and is connected with the buckle and arranged perpendicularly. Correspondingly, the groove 12 on the inner wall of the shell 1 can be arranged at the end close to the opening of the shell.

[0071] In some embodiments, referring to Figure 8 and Figure 9 The sliding part 21 can be arranged on the side of the wall 25 away from the body part 24. For example, the wall 25 is provided with an extension part 211 on each side away from the body part 24. The inner wall of the shell 1 is provided with two grooves 12 corresponding to the two extension parts 211. The groove 12 is arranged at the end of the inner wall of the shell 1 away from the opening of the shell 1. Each groove 12 is defined by the first convex rib 14 and the second convex rib 15 arranged at intervals. During assembly of the middle frame assembly 2, at least part of the extension part 211 can be located in the groove 12 and slide along the groove 12.
