[0032] like Figure 1-4 As shown, an embodiment of the utility model provides a support structure 1 , which can be matched with other structures to form a shell assembly of a vacuum cleaner 100 .

[0033] Specifically, the bracket structure 1 provided in this embodiment includes a bracket body 11, a connecting portion 13 integrally provided with the bracket body 11, a mainboard mounting portion 12, a motor pressing portion 18 and a battery pack pole piece mounting portion; wherein,

[0034] The bracket body 11 cooperates with the lower cover 2 of the shell assembly through the connecting part 13 to form an accommodating cavity, and presses the motor assembly 5 accommodated in the accommodating cavity through the motor pressing part 18. The main bracket can also install the main control board 3 and the battery pack pole piece frame 6 through the mainboard mounting part 12 and the battery pack pole piece mounting part respectively.

[0035] The bracket structure 1 provided in this embodiment is provided with a connection portion 13, a mainboard mounting portion 12, a motor pressing portion 18 and a battery pack pole piece mounting portion which are integrally provided with the bracket body 11. Therefore, it can not only be assembled with the lower cover 2 of the shell assembly, but also can be pressed on the motor assembly 5 as a motor cover to achieve the fixation of the motor assembly 5, and can support the main control board 3 and the battery pack pole piece frame 6. This embodiment provides a bracket structure 1 which can integrate three connection functions. On the one hand, it can make the space layout compact, improve the space utilization, and reduce the space of the vacuum cleaner 100 body. On the other hand, it can reduce the number of parts of the vacuum cleaner 100 body, thereby reducing the cost and improving the assembly efficiency. On the third hand, the adjustment of the space layout makes it easy to arrange the mainboard mounting portion 12 of the bracket structure 1 below the handle of the vacuum cleaner 100 body, so that the main control board 3 can integrate the button 9 and the indicator light 7 without adding a button 9 board separately, further reducing the cost of the host.

[0036] In one embodiment, a first side surface is formed on the bracket body 11 , and at least a portion of the first side surface is formed as the mainboard mounting portion 12 .

[0037] Specifically, the first side surface is located on the side of the bracket body 11 away from the lower cover 2, and at least a part of the area is a plane adapted to the shape of the circuit board of the main control board 3, so that the main control board 3 can be easily installed on the first side surface.

[0038] In one embodiment, a clamping member 14 is further provided on the first side surface, and the main control board 3 is mounted on the main board mounting portion 12 via the clamping member 14 .

[0039] Specifically, there are two clamping members 14 , which are arranged opposite to each other and are suitable for being adapted and clamped with a group of side edges opposite to the main control board 3 , so that the main control board 3 is connected to the bracket body 11 .

[0040] In this embodiment, the clamping member 14 is provided to make the connection between the main control board 3 and the bracket body 11 simple and convenient, thereby improving the assembly efficiency.

[0041] Of course, in other embodiments, the main control board 3 may also be connected to the installation plane by welding or bonding.

[0042] Optionally, the clamping member 14 includes a connecting member and a protrusion, the connecting member is connected to the bracket body 11, and the two protrusions are respectively arranged on opposite sides of the connecting member. The connecting member is erected on the first side surface; a gap is formed between the two protrusions and the first side surface, and the minimum distance between the two protrusions is greater than the length of the main control board 3. When the main control board 3 is installed, the connecting member is deformed by force, so that the main control board 3 is fixed in the gap between the protrusion and the installation plane.

[0043] Optionally, guide surfaces are provided on the side surfaces opposite to the protrusions, and the main control mounting plate is guided by the guide surfaces to facilitate assembly.

[0044] In one embodiment, the first side surface is further provided with an escape hole, which is suitable for accommodating part of the main control board 3 in the accommodating cavity. In this way, the space formed by the bracket body 11 and the lower cover 2 can be reasonably utilized, thereby making the space more compact and improving the space utilization rate.

[0045] In one embodiment, a limiting column 15 is further provided on the first side surface, and the limiting column 15 is suitable for fitting and positioning with the limiting hole of the main control board 3 .

[0046] Specifically, there are two limit posts 15 , and both limit posts 15 are disposed between two clamping members 14 , and are used to fit and position with the limit holes of the main control board 3 .

[0047] In this embodiment, the cooperation between the limiting column 15 and the limiting hole can prevent the main control board 3 from moving on the bracket body 11, thereby improving the stability of the connection.

[0048] In one embodiment, the bracket body 11 further has a second side surface, on which a pressing piece is formed to be radially adapted to the motor assembly 5 , and the pressing piece is formed as a motor pressing portion 18 .

[0049] The second side surface is arranged opposite to the first side surface and specifically faces the lower cover 2. The pressing piece is formed on the second side surface and is specifically located in the accommodating cavity formed by the bracket body 11 when the bracket body 11 is matched with the lower cover 2. Since the pressing piece is adapted to the motor assembly 5, the motor assembly 5 in the cavity can be pressed.

[0050] Optionally, the press-fitting piece may include a pair of first ribs and second ribs arranged in parallel, wherein the first end of the first rib is arranged perpendicular to the second side surface, and the second end is formed with a press-fitting groove adapted to the motor assembly 5. There are multiple second ribs, and the multiple second ribs are arranged perpendicular to the second side surface, and the two ends are respectively connected to the first ribs, and the height of each second rib is the same as the height of the first rib at the position where it is connected. In this way, not only the relative width of the press-fitting piece can be increased, the pressing area of ​​the motor assembly 5 can be increased, and the pressing effect of the motor assembly 5 can be ensured, but also the material of the press-fitting piece can be saved, the cost can be reduced, and the weight of the support structure 1 can be reduced.

[0051] Of course, in other embodiments, the pressing piece may also be provided as a block structure with a pressing groove.

[0052] In one embodiment, the second side surface is further formed with a stopper 19 adapted to abut against the axial direction of the motor pressing part 18. The stopper 19 is located at one end of the pressing part and is used to stop the end of the motor assembly 5. In this way, the axial direction of the motor assembly 5 can be limited by the stopper 19, thereby further ensuring the stability of the main body of the vacuum cleaner 100.

[0053] Optionally, the stopper 19 is a hollow column, and the number of the hollow column is two, and they are spaced apart and arranged on the adjacent two side plates 112. Such an arrangement can improve the strength of the stopper 19 on the one hand, and can also improve the strength of the bracket body 11 on the other hand.

[0054] In one embodiment, the end of the bracket body 11 is also formed with a plug-in tube body 16 whose inner wall is provided with a clamping portion 17, and the plug-in tube body 16 is formed as a battery pack pole piece mounting portion, and the battery pack pole piece frame 6 is adapted to be clamped with the clamping portion 17 to be partially accommodated in the plug-in tube body 16.

[0055] Specifically, the plug-in tube body 16 is a square tube, one end of which is connected to the bracket body 11, and the other end is a plug-in end, and the shape of the plug-in end port is adapted to the shape of the battery pack pole piece frame 6. The clamping portion 17 is arranged on the inner wall of the plug-in end of the plug-in tube body 16. One end of the battery pack pole piece frame 6 is inserted into the plug-in tube body 16 from the plug-in end, and is adapted to be clamped with the clamping portion 17 to be fixedly connected to the bracket body 11.

[0056] The battery pack pole piece mounting portion of this embodiment is provided with a plug-in tube body 16 having a snap-in clamping portion 17, so that the battery pack pole piece frame 6 can be fixed to the bracket body 11 by plugging, making the installation of the battery pack pole piece frame 6 convenient, thereby improving the assembly efficiency.

[0057] In one embodiment, the clamping portion 17 includes a stop plug 172 and a buckle 171 spaced apart along the axial direction of the plug-in tube body 16, and the battery pack pole piece frame 6 is fixed between the stop plug 172 and the buckle 171. Thus, one end of the battery pack pole piece frame 6 inserted into the plug-in tube body 16 abuts against the stop plug 172, and the other end abuts against the buckle 171, and is then confined in the plug-in tube body 16, thereby achieving relative fixation with the plug-in tube body 16.

[0058] In one embodiment, a group of relatively arranged first tube circumferences 161 and a group of relatively arranged second tube circumferences 162 are provided on the circumference of the plug-in tube body 16, and the second tube circumferences 162 are arranged between two adjacent first tube circumferences 161; a buckle 171 is provided on the inner wall of each first tube circumference 161, and a stop plug 172 is provided on the inner wall of each second tube circumference 162, and the battery pack pole piece frame 6 is plugged into the inner side of the buckle 171 based on the elastic deformation of the first tube circumference 161.

[0059] Specifically, the first tube peripheries 161 are arranged at the centers of a group of opposite sides of the plug-in tube body 16, and the length of each first tube periphery 161 along the circumferential direction of the plug-in tube body 16 is less than one quarter of the circumference of the plug-in tube body 16; the second tube peripheries 162 are arranged between adjacent first tube peripheries 161, and the length of each second tube periphery 162 along the circumferential direction of the plug-in tube body 16 is greater than one quarter of the circumference of the plug-in tube body 16, so that the relatively arranged first tube peripheries 161 have a certain elastic force.

[0060] The stop plug 172 is a protrusion formed on the inner wall of the second tube 162, and the buckle 171 is a protrusion formed on the inner wall of the first tube 161 and having a guide surface. Therefore, when the battery pack pole piece frame 6 is plugged into the plug-in tube body 16, the buckle 171 can be squeezed to deform the first tube 161 and then be stuck between the stop plug 172 and the buckle 171.

[0061] The above arrangement of this embodiment can reduce the difficulty of plugging in the battery pack pole piece frame 6, thereby facilitating the improvement of assembly efficiency.

[0062] Optionally, a through hole is provided in the middle of each first tube periphery 161 , which can further improve the elasticity of the first tube periphery 161 .

[0063] In one embodiment, the bracket body 11 includes a main board 111, and the main board 111 has a first side surface and a second side surface that are arranged opposite to each other; the main board mounting portion 12 is arranged on the first side surface, the battery pressing portion is arranged on the second side surface, and the battery pack pole piece frame 6 mounting portion is arranged on the end of the main board 111. Such an arrangement can reduce the mutual interference between the main board mounting portion 12, the battery pressing portion and the battery pack pole piece frame 6 mounting portion, so that the space utilization is reasonable and compact, and the space of the whole machine is reduced.

[0064] In one embodiment, the bracket body 11 also includes a side panel 112 and a connecting panel 113. There are two side panels 112, which are respectively connected to the opposite sides of the main panel 111. The connecting panel 113 is located on the other side of the side panel 112 relative to the connecting panel 113, and both ends are respectively connected to the two side panels 112.

[0065] Specifically, the first end of the side plate 112 is connected to the main board 111, and the second end of the side plate 112 is a free end and is suitable for abutting against the lower cover 2 when the bracket body 11 is assembled with the lower cover 2. The connecting plate 113 is located between the battery pressing part and the battery pack pole frame 6 installation part.

[0066] Optionally, the first end of the side panel 112 is a flat plate and vertically connected to the main panel 111; or the second end of the side panel 112 is an arc-shaped plate, which can further increase the structural strength of the main support and improve the compressive stress resistance of the support body 11.

[0067] By providing the side panels 112 and the connecting panels 113, on the one hand, the structural strength of the bracket body 11 can be improved and its service life can be increased. On the other hand, the increased thickness of the main bracket can correspondingly reduce the thickness of the lower cover 2, which can facilitate the assembly and maintenance of the motor assembly 5.

[0068] Optionally, the first rib plate and the second rib plate in the pressed part extend to the side plate 112 , and the side surface of the stopper 19 is formed by the side plate 112 .

[0069] Optionally, along its length direction, the side plate 112 extends to the plug-in square tube and is connected to the side wall of the plug-in square tube.

[0071] Specifically, there are two first through holes 131, which are arranged on one side of the bracket body 11 away from the mounting portion of the battery pack pole frame 6, and there are two second through holes 132, which are arranged on the connecting plate 113. The main bracket is connected to the lower cover 2 by threaded fasteners 4 inserted in the first through holes 131 and the second through holes 132.

[0072] Optionally, the second side surface of the main board 111 is further provided with a support column surrounding the first through hole 131, and the connecting plate 113 is provided with a support column surrounding the second through hole 132 on the side away from the main board 111. By providing the support column, the deformation of the main board 111 and the connecting plate 113 can be reduced when the bracket body 11 is connected to the lower cover 2 through the connecting portion 13.

[0073] In one embodiment, a plurality of avoidance grooves that are recessed toward each other are further provided on the side plate 112. The avoidance grooves are used to avoid the protruding structure of the lower cover 2, thereby facilitating the connection between the bracket body 11 and the lower cover 2. At the same time, since the avoidance grooves are formed by the side plates 112 being recessed toward each other, the strength of the side plates 112 can be further improved.
