[0026] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, each embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in each embodiment of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not constitute any limitation, and the various embodiments can be combined with each other and referenced to each other without contradiction.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0028] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0029] With the continuous development of various types of power tools, some power tools have begun to be equipped with independent power supply devices. With independent power supply devices, the power tool can be used normally without power cord, that is, there is no need to draw power from the outside. The power supply device includes a battery pack, which can be installed near the handle of the power tool. The battery pack can be set with a rechargeable lithium battery pack. In addition, the battery pack can be removed from the handle so that the removed battery pack can be charged and replaced with a battery pack with sufficient power. The battery pack can also be charged using a charging cable without removing it from the handle.

[0030] The battery pack is usually provided with an indicator light, which is installed inside the battery pack and can display the battery pack power level or other information about the working status of the power tool. Since the cover on the battery pack usually does not have a light-transmitting function, a separate lampshade is designed to allow the light emitted by the indicator light to propagate to the outside world, so as to convey relevant information to the outside world. The lampshade is made of light-transmitting materials, such as common light-transmitting plastics.

[0031] In order to effectively fix the lampshade when installing it, some embodiments of the present application provide a lampshade matching structure. When the lampshade is installed, it matches with the side cover. Ribs are provided on the side cover, and a receiving space is provided at a corresponding position of the lampshade. When the protruding portion of the lampshade abuts against the inner side of the side cover, the ribs on the side cover will be inserted into the corresponding receiving space. Thereby, the lampshade is positioned at the matching position on the side cover and the movement of the lampshade is restricted. Thereby, the lampshade can be effectively fixed when installed with the help of the matching between the side covers.

[0032] Combine the following Figures 1 to 9 The lampshade matching structure provided by some embodiments of the present application is described.

[0033] like Figures 1 to 6As shown, a lampshade matching structure provided by some embodiments of the present application includes a side cover 11 and a lampshade 12. The side cover 11 is provided with a receiving area 111 that is recessed inward from the edge, and the receiving area 111 is provided with a plurality of ribs 112 arranged along a preset direction. The lampshade 12 includes a main body 121, and protrusions 122 distributed at both ends of the main body 121 along a preset direction, the main body 121 is provided with an inner cavity 1212 with an opening 1211, and a plurality of notches 1213 located at the edge of the opening 1211, the plurality of notches 1213 are respectively connected with the inner cavity 1212 to form a plurality of receiving spaces 1214 arranged along a preset direction, and the plurality of receiving spaces 1214 correspond to the plurality of ribs 112 one by one. When the protrusion 122 abuts against the inner side of the side cover 11, the opening 1211 faces the inner side of the side cover 11, and the plurality of ribs 112 are inserted into the corresponding receiving spaces 1214.

[0034] The side cover 11 is a cover body located on the side when the battery pack is placed normally. By installing the lampshade 12 on the side cover 11, it is beneficial for the operator to observe the indicator light status from the side and top of the battery pack at the same time, so as to enhance the user experience. The side cover 11 is provided with an inwardly recessed accommodation area 111 at the edge. The accommodation area 111 provides space for the installation of the lampshade 12, and the lampshade 12 can be placed in the accommodation area 111. Thereby avoiding the occupation of space. The accommodation area 111 is provided with a plurality of ribs 112 arranged along a preset direction, and the ribs 112 can provide a basis for limiting the lampshade 12. The preset direction is the extension direction of the edge of the side cover 11.

[0035] The lampshade 12 is the part of the battery pack for the indicator light to emit light to the outside world. The operator can observe the state of the indicator light from the lampshade 12 to determine the information reflected by the indicator light. The main body 121 is the main part of the lampshade 12. The main body 121 is provided with an inner cavity 1212. The inner cavity 1212 corresponds to the position of the indicator light and provides space for light propagation. A plurality of notches 1213 are provided at the edge of the opening 1211 of the inner cavity 1212. The notches 1213 cooperate with the inner cavity 1212 to form a plurality of accommodating spaces 1214 corresponding to the plurality of ribs 112 on the side cover 11. After the ribs 112 are inserted into the corresponding accommodating spaces 1214, the movement of the lampshade 12 to the side of the opening 1211 can be restricted. The protrusion 122 is the part where the lampshade 12 abuts against the side cover 11 front and back. The protrusion 122 can be inserted into the inner side of the side cover 11, thereby restricting the movement of the lampshade 12 to the outside of the side cover 11. The protrusion 122 and the main body 121 may be an integrally formed structure, or may be separate components connected to form a whole.

[0036] The lampshade matching structure provided in some embodiments of the present application integrates the lampshade 12 on the side cover 11 of the battery pack. The side cover 11 is provided with a receiving area 111 that provides an installation space for the lampshade 12. The receiving area 111 is provided with a plurality of ribs 112, and the lampshade 12 is provided with a plurality of receiving spaces 1214. When the protrusion 122 of the lampshade 12 abuts against the inner side of the side cover 11, each rib 112 is inserted into the corresponding receiving space 1214. Therefore, after the lampshade 12 is installed, the movement of the lampshade 12 is limited by matching with the side cover 11, so as to achieve effective fixation of the lampshade 12.

[0037] like Figure 5 and Figure 6 As shown, the main body 121 may include a first cavity wall 101 and a second cavity wall 102 that are arranged opposite to each other, and at least one of the first cavity wall 101 and the second cavity wall 102 is provided with a notch 1213 .

[0038] The first cavity wall 101 and the second cavity wall 102 are parts of the main body 121 distributed along a preset direction. The notch 1213 can be set on the first cavity wall 101 or the second cavity wall 102, or the notch 1213 can be set on both the first cavity wall 101 and the second cavity wall 102. When the notch 1213 is set on the first cavity wall 101 or the second cavity wall 102, the rib 112 is inserted into the notch 1213 on one side of the inner cavity 1212 and the inner cavity 1212. When the notch 1213 is set on both the first cavity wall 101 and the second cavity wall 102, the rib 112 is inserted into the notch 1213 on both sides of the inner cavity 1212 and the inner cavity 1212. By reducing the number of notches 1213, the structure of the main body 121 can be simplified, which is convenient for the molding of the main body 121. By increasing the number of notches 1213, the matching area between the rib 112 and the main body 121 can be increased, thereby improving the stability of the lampshade 12 during installation.

[0039] In addition, the ribs 112 inserted into the accommodating space 1214 can also effectively prevent light leakage, that is, it can better separate the light-transmitting area of ​​the main body 121 to prevent light from passing through the ribs 112 and overflowing.

[0040] In some embodiments, the main body 121 may further include a display portion 103 connecting the first cavity wall 101 and the second cavity wall 102 , wherein a portion of the display portion 103 close to the first cavity wall 101 is further away from the protrusion 122 than a portion of the display portion close to the second cavity wall 102 .

[0041] The display part 103 is a light-transmitting part of the main body 121. The relevant information reflected by the indicator light can be judged by the light transmittance of the display part 103. The part of the display part 103 close to the first cavity wall 101 is the bottom of the display part 103, and the part of the display part 103 close to the second cavity wall 102 is the top of the display part 103. By making the bottom of the display part 103 further away from the protrusion 122, the display part 103 is formed into a shape with a more protruding bottom. In this way, it is convenient for the operator to observe the light transmittance of the display part 103 from above, and the display angle of the display part 103 is improved.

[0042] like Figure 5 As shown, the display portion 103 may be provided with a plurality of recessed areas 1031 corresponding one-to-one to the plurality of receiving spaces 1214 , and a plurality of display areas 1032 formed by partitioning the plurality of recessed areas 1031 .

[0043] The position of the recessed area 1031 of the display part 103 corresponds to the position of the accommodating space 1214, and after a plurality of recessed areas 1031 are formed, the display part 103 can form a display area 1032 at a position adjacent to the recessed area 1031. By setting the recessed area 1031, the display of the display area 1032 can be made clearer, and will not be easily disturbed by the light of the adjacent display area 1032. In actual situations, the recessed area 1031 can be formed into a shape in which the width gradually decreases from the outside to the inside, so that the separation effect is more obvious. The recessed area 1031 can also be formed into a shape in which the width is basically straight from the outside to the inside.

[0044] In some embodiments, each rib 112 may include a connected partition 1121 and an extension 1122, the partition 1121 is inserted into the corresponding accommodation space 1214 and abuts against the display portion 103, and the extension 1122 is used to insert the circuit board 24 ( Fig. 9 Groove 241 at the edge).

[0045] The partition 1121 is the part where the rib 112 cooperates with the accommodating space 1214. The partition 1121 can be completely inserted into the accommodating space 1214 and abut against the display portion 103. Thus, the main body 121 of the lampshade 12 plays a better role in partitioning and effectively avoids the occurrence of light leakage. The extension 1122 is the part of the rib 112 that protrudes toward the inner side of the side cover 11. When assembling the battery pack, the extension 1122 can be inserted into the groove 241 at the edge of the circuit board 24 to play a positioning role when fixing, thereby improving the fixing effect of the side cover 11 when installing.

[0046] like Figure 1 and Figure 2 As shown, the second cavity wall 102 can remain flush with the edge of the side cover 11 .

[0047] The second cavity wall 102 is located at the top of the main body 121. After the lampshade 12 and the side cover 11 are matched, the second cavity wall 102 is kept flush with the edge of the side cover 11. In this way, the normal positioning of the side cover 11 during installation will not be affected, and the upper and lower limits of the lampshade 12 can be completed by the contact between the edge of the side cover 11 and the edge of the top cover 22 of the battery pack.

[0048] like Figure 4 As shown, the side cover 11 may be provided with an abutting surface 113 abutting against the protruding portion 122 , and a limiting surface 114 adjacent to the abutting surface 113 , and the limiting surface 114 and the abutting surface 113 are located on different planes.

[0049] The abutting surface 113 and the limiting surface 114 form a limiting area, which can limit the protrusion 122 of the lampshade 12. After the lampshade 12 and the side cover 11 are matched, the main body 121 of the lampshade 12 abuts against the abutting surface 113, and the abutting surface 113 is located on the inner side of the lampshade. At the same time, the limiting surface 114 located on a different plane from the abutting surface 113 can limit the edge of the protrusion 122 to prevent the lampshade 12 from moving in the left and right directions.

[0050] like Figure 4 As shown, the side cover 11 may be provided with a mounting hole 115 , and the limiting surface 114 is provided adjacent to the mounting hole 115 .

[0051] By providing the limiting surface 114 near the mounting hole 115 , the fastener can be locked near the lampshade 12 , which is beneficial to improving the fixing effect of the lampshade 12 .

[0052] like Figures 7 to 9 As shown, some embodiments of the present application further provide a battery pack, which includes a battery cell holder 21, a top cover 22 and the above-mentioned lampshade matching structure. The battery cell holder 21 is equipped with multiple battery cells 23 and a circuit board 24 electrically connected to the multiple battery cells 23. The top cover 22 covers the circuit board 24. The side cover 11 of the lampshade matching structure covers one side of the multiple battery cells 23, and the side of the lampshade 12 of the lampshade matching structure away from the side cover 11 abuts against the top cover 22.

[0053] The battery pack can be assembled by closing the left and right covers. The top cover 22 and the side cover 11 are fastened together on the battery holder 21 by fasteners. At the same time, the lampshade 12 is fixed to the receiving area 111 of the side cover 11 by cooperating with the side cover 11. And the lampshade 12 is fixed in the upper and lower directions by abutting against the top cover 22.

[0054] By effectively fixing the lampshade 12 , the lampshade 12 can function normally to transmit light, so as to transmit the relevant information reflected by the indicator light 242 to the outside.

[0055] Some embodiments of the present application also provide an electric tool, which includes the above-mentioned battery pack.

[0056] The power tool can be driven by the power provided by the battery pack, and the power level, fault and other information can be judged by the information reflected by the indicator light on the battery pack. The power tool can be an electric wrench, an electric grinder or a reciprocating saw.

[0057] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present application, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
