Description

Technical Field

[0001] This application relates to the field of vacuum cleaner technology, and in particular to the mounting structure of a battery pack and motor for a handheld vacuum cleaner. Background Technology

[0002] With the upgrading of home cleaning needs, handheld vacuum cleaners have become one of the mainstream household cleaning devices due to their portability and flexibility. The battery pack and motor are the core components of a handheld vacuum cleaner: the battery pack provides the power source for the entire machine, and its installation stability and ease of installation and removal directly affect the user's battery replenishment efficiency; the motor provides negative pressure power for the suction components, and its operational stability, heat dissipation, and vibration control are crucial to the vacuum cleaner's suction performance and lifespan. Therefore, the installation structure design of the battery pack and motor is a key factor determining the overall performance of a handheld vacuum cleaner.

[0003] Currently, the battery pack and motor installation methods of handheld vacuum cleaners on the market are mainly divided into two categories: one is the decentralized installation, in which the battery pack is fixed to the handle end of the main body with multiple screws, and the motor is bolted to the nozzle end of the main body, and the two are connected by wires and terminals; the other is the integrated installation, in which the battery pack and motor are placed in a closed cavity and fixed by a bracket inside the cavity, and the electrical connection uses a plug-in wire connector.

[0004] Regarding the aforementioned technologies, the inventors believe that in the existing structures, the electrical connection between the motor, battery pack, and control board relies heavily on long wires. Long wires not only increase line resistance but also result in significant energy loss during power supply. Summary of the Invention

[0005] The purpose of this application is to provide an installation structure for the battery pack and motor of a handheld vacuum cleaner, in order to improve the existing structure where the electrical connection between the motor, battery pack and control board relies on long wires. Long wires not only increase the line resistance, but also lead to greater energy loss during the power supply process.

[0006] The mounting structure for the handheld vacuum cleaner battery pack and motor provided in this application adopts the following technical solution: The mounting structure for a handheld vacuum cleaner battery pack and motor includes a vacuum cleaner end cap that mounts the motor and has a suction port, and a vacuum cleaner housing that encloses the motor. A fixing frame for holding the battery pack is provided on the outside of the vacuum cleaner housing. A connecting component is provided on the side of the vacuum cleaner housing facing the end of the vacuum cleaner housing and connected to the side away from the vacuum cleaner end cap. The connecting component includes a connecting frame connected to the fixing frame and a housing connected to the connecting frame and the fixing frame. A control board that is electrically connected to the battery pack and the motor is provided in the connecting frame.

[0007] By adopting the above technical solution, the motor is placed inside the vacuum cleaner housing and the battery pack is placed in a fixed frame outside the vacuum cleaner housing, preventing vibration transmission and electromagnetic interference caused by direct contact between the two. At the same time, it reduces the impact of battery pack heat on the motor and extends the life of core components. The connecting component serves the dual function of connecting the fixed frame and the vacuum cleaner housing and accommodating the control board, simplifying the overall structure, reducing the number of parts, and reducing assembly complexity. The control board is built into the connecting component and can directly form a short-path electrical connection with the battery pack and the motor, reducing wire length, reducing line loss, improving power supply efficiency, and avoiding assembly errors or the risk of falling off during use caused by messy wires.

[0008] Optionally, the outer wall of the vacuum cleaner housing is provided with limiting plates on both sides of the fixed frame. The limiting plates are provided with a sliding groove along the length of the limiting plates at the angle between the limiting plates and the vacuum cleaner housing. The fixed frame is provided with protrusions corresponding to the sliding grooves and limiting grooves that are adapted to the limiting plates on both sides.

[0009] By adopting the above technical solution, the protrusion of the fixed frame slides along the groove of the limiting plate, which can guide the fixed frame to be installed along the preset path, avoid lateral deviation, ensure the accurate relative position of the fixed frame and the shell, and prevent misalignment of the battery pack with the control board after installation; the matching structure of the limiting groove and the limiting plate can limit the longitudinal displacement of the fixed frame, prevent the fixed frame from loosening due to the vibration of the vacuum cleaner during use, and thus prevent poor contact between the battery pack and conductive parts; the guiding effect of the groove allows the fixed frame to be quickly positioned without repeated adjustments, reducing assembly difficulty and improving production efficiency.

[0010] Optionally, the fixing frame is arranged in an arc shape along the outer side of the vacuum cleaner housing to fit the vacuum cleaner housing, the edge of the connecting frame abuts against the end of the limiting plate, and the outer side wall of the outer shell is aligned with the outer side wall of the vacuum cleaner housing and the fixing frame.

[0011] By adopting the above technical solution, the fixed frame is arc-shaped and fits the outer side of the vacuum cleaner shell, which can closely fit the shell contour and avoid the space waste caused by the traditional straight frame. This makes the whole machine structure more compact and meets the portable and compact use requirements of handheld vacuum cleaners. The edge of the connecting frame abuts against the end of the limiting plate, which can form an axial limit on the fixed frame and prevent the fixed frame from sliding out along the slide groove, further enhancing the installation stability of the fixed frame. The side wall of the outer shell is aligned with the outer wall of the vacuum cleaner shell and the fixed frame, eliminating steps or gaps between components. This not only improves the flatness of the overall appearance of the machine, but also reduces dust accumulation in the gaps, while enhancing the overall structural integrity and improving the drop and impact resistance.

[0012] Optionally, the side wall of the vacuum cleaner housing is provided with heat dissipation holes corresponding to the motor inside the vacuum cleaner housing; the circumferential side wall of the vacuum cleaner end cover is provided with several positioning grooves; a positioning post is provided at one end of the vacuum cleaner housing facing the vacuum cleaner end cover and inserted into the positioning groove; the positioning post is fixed to the inner side wall of the positioning groove by bolts.

[0013] By adopting the above technical solution, the heat dissipation holes are opened on the side wall of the vacuum cleaner housing and corresponding to the motor position. This allows the heat generated by the motor to be directly discharged to the outside of the housing, preventing heat from accumulating inside the housing and causing the motor to overheat. This prevents the motor from triggering the protection mechanism due to overheating, reducing power or burning out the windings, and extending the motor's service life. The positioning pin is inserted into the positioning slot to achieve initial positioning, and then fixed with bolts to form a rigid connection. This prevents the end cover from separating from the housing due to vibration during use, while ensuring the coaxiality of the suction port and the motor. This prevents air duct blockage or suction loss due to misalignment and improves suction efficiency. The bolt connection facilitates subsequent disassembly of the end cover for motor maintenance without damaging the overall structure, reducing maintenance costs.

[0014] Optionally, the vacuum cleaner housing and the connecting frame have snap-fit ​​grooves on both sides, and the outer shell is provided with an elastic buckle that inserts into the snap-fit ​​groove facing the vacuum cleaner housing. The end of the elastic buckle is set with an inclined surface, and the vacuum cleaner housing has an inclined protrusion that engages with the end of the elastic buckle. The elastic buckle is provided with a pressing groove on the outside of the vacuum cleaner housing.

[0015] By adopting the above technical solution, the elastic buckle is inserted into the snap-fit ​​groove and engages with the beveled protrusion, achieving rapid fixation of the outer shell without the need for screws or other fasteners. The pressing groove allows users to easily press the elastic buckle to release the engagement, enabling quick disassembly of the outer shell and greatly improving the convenience of control board maintenance or component replacement. The beveled design of the end of the elastic buckle and the beveled protrusion allows the elastic buckle to automatically deform and slide into the engagement position when inserted into the snap-fit ​​groove, avoiding damage to the elastic buckle caused by hard insertion and removal, and improving assembly smoothness. The beveled protrusion can also provide reverse limiting for the elastic buckle, preventing the elastic buckle from loosening due to vibration or external force during use, ensuring that the outer shell is always firmly connected, and preventing dust and moisture from entering the connecting components through the gaps in the outer shell and damaging the control board.

[0016] Optionally, the end of the vacuum cleaner housing away from the vacuum cleaner end cap is provided with an electrical connector that is electrically connected to the motor, and the connecting frame is provided with a connecting slot that is electrically connected to the control board and plugs into the electrical connector.

[0017] By adopting the above technical solution, the motor and control board can be electrically connected simply by plugging the connecting slot of the connecting frame into the electrical connector of the housing. This reduces assembly steps, avoids wiring errors, and improves production efficiency. The stable contact area of ​​the plug-in structure prevents poor contact caused by vibration in the wire connection, ensuring stable power supply to the motor and thus ensuring stable suction power of the vacuum cleaner. At the same time, during maintenance, the connection between the motor and the control board can be disconnected simply by separating the connecting slot from the electrical connector, without cutting or removing the wires, reducing maintenance difficulty and avoiding damage caused by repeated disassembly and reassembly of the wires.

[0018] Optionally, the vacuum cleaner housing is provided with baffles on both sides of the snap-fit ​​groove, which correspond to the elastic buckles and are connected to the two ends of the inclined protrusion.

[0019] By adopting the above technical solution, the baffle can limit the lateral displacement of the elastic buckle during use, preventing the elastic buckle from shifting due to vacuum cleaner vibration or accidental collision, which would cause the elastic buckle to fail to engage with the inclined protrusion, thus preventing the shell from falling off. The connection between the baffle and the two ends of the inclined protrusion can form a support structure around the elastic buckle, enhancing the structural strength of the vacuum cleaner shell and the connecting frame at the snap-fit ​​position, preventing the shell or connecting frame from cracking due to the elastic buckle being stressed, and extending the service life of the components. The baffle can also act as a guide when the elastic buckle is inserted into the snap-fit ​​groove, ensuring that the elastic buckle is accurately aligned with the inclined protrusion and improving assembly accuracy.

[0020] Optionally, the housing has a mounting groove, a light shield that contacts the control panel is provided in the mounting groove, and an operation panel that abuts against the light shield and is electrically connected to the control panel is provided on the outside of the housing.

[0021] By adopting the above technical solution, the light shield contacts the control board, blocking external light from interfering with the photosensitive elements on the control board, avoiding light-induced component mis-triggering or performance fluctuations, and ensuring stable operation of the control board; the operation panel is pressed against the light shield, which not only fixes the light shield but also provides an operation interface for the user, eliminating the need for additional fixing structures and simplifying the internal layout of the casing; the light shield can form a buffer between the operation panel and the control board, preventing the user from directly damaging the control board components with excessive force when pressing the operation panel, while also reducing the risk of dust entering the control board through the gaps in the operation panel.

[0022] Optionally, the fixed frame is provided with a connecting bracket connected to the battery pack. The connecting bracket is also arc-shaped. The connecting bracket is provided with a conductive spring that is electrically connected to the battery pack and a spring connector that is electrically connected to the conductive spring and the control board. The end of the spring connector is bent and soldered to the control board.

[0023] By adopting the above technical solution, the connecting bracket is arc-shaped and fits the fixed frame, closely conforming to the outline of the battery pack. This ensures that the battery pack does not wobble within the fixed frame, avoiding damage to the casing or loosening of electrical connections caused by battery pack collisions during use. The conductive spring contacts the battery pack elastically, accommodating minor displacements during battery pack installation and minimizing the possibility of poor contact due to hard contact. At the same time, the elasticity of the spring ensures stable contact pressure even after long-term use. The bent spring connector is connected to the control board via soldering, providing high connection strength and effectively preventing the risk of wire connection detachment, ensuring stable current transmission from the battery pack to the control board. The elastic connection structure is compatible with dimensional errors of different batches of battery packs, reducing the precision requirements for component processing and lowering production costs.

[0024] Optionally, the connecting frame is provided with a positioning side plate on the side facing the control plate. The positioning side plate is positioned along the edge of the control plate, and the connecting frame is provided with a limiting post that contacts the control plate and is connected to the outer shell. The control plate is provided with a clearance groove corresponding to the limiting post.

[0025] By adopting the above technical solution, the positioning side plate is set along the edge of the control plate, which can limit the lateral displacement of the control plate and prevent the control plate from shifting due to vibration during use, which could cause the electronic components on the control plate to collide and be damaged with the connecting frame, or misalign with the electrical connection parts; the limiting post passes through the relief groove of the control plate and is connected to the outer shell, which can press the control plate longitudinally to prevent the control plate from shaking up and down and ensure stable contact between the control plate and the light shield and the spring connector; the design of the relief groove can avoid collision or short circuit between the limiting post and the electronic components on the control plate, ensuring the normal operation of the control plate. At the same time, the connection between the limiting post and the outer shell can further enhance the integrity of the connecting frame and the outer shell and improve the structural stability.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By placing the motor inside the vacuum cleaner housing and the battery pack in a fixed frame outside the vacuum cleaner housing, the overall structure is simplified and the assembly complexity is reduced. The control board is built into the connecting assembly and can directly form a short-path electrical connection with the battery pack and motor, reducing wire length, reducing line loss, and improving power supply efficiency. 2. The protrusions of the fixed frame slide along the groove of the limiting plate, which can guide the fixed frame to be installed along the preset path, avoid lateral deviation, ensure the accurate relative position of the fixed frame and the housing, and prevent misalignment of the battery pack with the control board after installation; the matching structure of the limiting groove and the limiting plate can limit the longitudinal displacement of the fixed frame, prevent the fixed frame from loosening due to the vibration of the vacuum cleaner during use, and thus prevent poor contact between the battery pack and conductive parts; 3. After the elastic buckle is inserted into the snap-fit ​​groove, it engages with the beveled protrusion, achieving quick fixation of the outer casing without the need for screws or other fasteners; pressing the groove allows users to easily press the elastic buckle to release the engagement, enabling quick disassembly of the outer casing and greatly improving the convenience of control board maintenance or component replacement; the beveled design of the end of the elastic buckle and the beveled protrusion allows the elastic buckle to automatically deform and slide into the engagement position through the beveled guide when inserted into the snap-fit ​​groove, avoiding damage to the elastic buckle caused by hard insertion and removal, and improving assembly smoothness.

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0030] The mounting structure of the battery pack and motor of the handheld vacuum cleaner is shown in the reference. Figure 1 , Figure 2 and Figure 3The system includes core components such as a vacuum cleaner end cap 1, a vacuum cleaner housing 2, a fixing frame 4, a connecting assembly 6, a battery pack 5, a motor 3, and a control board 63. The vacuum cleaner end cap 1 has a suction port at its center, with a pre-drilled mounting position on the inside. The motor 3 is bolted to this mounting position, and the output end of the motor 3 is collinear with the axis of the suction port, ensuring that the impeller driven by the motor 3 can precisely correspond to the suction port to create negative pressure. The vacuum cleaner housing 2 has a cylindrical structure, with one end facing the suction port. The vacuum cleaner end cap 1 is provided, and the vacuum cleaner housing 2 covers the motor 3 and is connected to the vacuum cleaner end cap 1. The circumferential side wall of the vacuum cleaner end cap 1 is evenly provided with a number of positioning grooves 11. Correspondingly, the end of the vacuum cleaner housing 2 facing the vacuum cleaner end cap 1 is integrally formed with positioning posts 24 matching the number of positioning grooves 11. After the positioning posts 24 are inserted into the positioning grooves 11, they are fixed to the inner side wall of the positioning grooves 11 by bolts passing through the positioning posts 24, so that the vacuum cleaner end cap 1 and the housing are firmly connected.

[0031] Reference Figure 1 , Figure 2 and Figure 5 Two limiting plates 21 are symmetrically arranged along the length of the outer wall of the vacuum cleaner housing 2, and the distance between the two limiting plates 21 is adapted to the width of the fixing frame 4. A sliding groove 22 is formed at the angle between the limiting plate 21 and the outer wall of the vacuum cleaner housing 2 along the length of the limiting plate 21. The two side walls of the fixing frame 4 are integrally formed with protrusions 41 that fit the sliding grooves 22. Simultaneously, the inner side wall of the fixing frame 4 has a limiting groove 42 that matches the thickness of the limiting plate 21. During installation, the protrusions 41 of the fixing frame 4 slide along the sliding grooves 22 until the limiting plate 21 is completely embedded in the limiting groove 42. At this point, the fixing frame is complete. The frame 4 is arc-shaped and fits against the outer side of the vacuum cleaner housing 2, so as to achieve precise positioning and fixation of the frame 4 and the vacuum cleaner housing 2. The inside of the fixed frame 4 is used to house the battery pack 5, and an arc-shaped connecting bracket 43 is also provided inside the fixed frame 4. The inner side wall of the connecting bracket 43 fits against the outer side wall of the battery pack 5. A conductive spring 431 is fixed on the connecting bracket 43. One end of the conductive spring 431 contacts the electrode of the battery pack 5, and the other end is connected to the spring connector 432. The end of the spring connector 432 is bent and fixed to the control board 63 by soldering, forming an electrical connection path between the battery pack 5 and the control board 63.

[0032] Reference Figure 3 and Figure 5The connecting component 6 includes a connecting frame 61 and a housing 62. The connecting frame 61 is located on the side of the fixed frame 4 facing the vacuum cleaner housing 2 away from the vacuum cleaner end cover 1. The edge of the connecting frame 61 abuts against the end of the limiting plate 21 to achieve axial limiting of the fixed frame 4. An electrical connector 27, which is electrically connected to the motor 3, is fixed to the end of the vacuum cleaner housing 2 away from the vacuum cleaner end cover 1. A corresponding connecting slot 611 adapted to the electrical connector 27 is opened on the connecting frame 61. The connecting slot 611 is electrically connected to the control board 63. When the connecting frame 61 and the vacuum cleaner housing are connected, the connecting frame 61 and the vacuum cleaner housing are connected. 2. During docking, the electrical connector 27 is inserted into the connection slot 611 to complete the electrical connection between the motor 3 and the control board 63. A positioning side plate 612 is integrally formed on the side of the connecting frame 61 facing the control board 63 along the edge of the control board 63, and the edge of the control board 63 fits against the positioning side plate 612. Several limiting posts 613 are also integrally formed on the connecting frame 61. The control board 63 is provided with corresponding relief grooves 631 that are adapted to the limiting posts 613. After the limiting posts 613 pass through the relief grooves 631, they are connected to the inner side wall of the outer shell 62 to achieve longitudinal fixation of the control board 63.

[0033] Reference Figure 1 , Figure 3 and Figure 4 and Figure 5 The vacuum cleaner housing 2 has several heat dissipation holes 23 on its side wall corresponding to the position of the motor 3, which can quickly dissipate the heat generated by the motor 3 to the outside of the vacuum cleaner housing 2. The connecting frame 61 and both side walls of the vacuum cleaner housing 2 have snap-fit ​​grooves 25. The outer shell 62 has an integrally formed elastic buckle 64 on the side facing the vacuum cleaner housing 2, which is adapted to the snap-fit ​​groove 25. The end of the elastic buckle 64 is beveled. Correspondingly, the vacuum cleaner housing 2 has an integrally formed beveled protrusion 26 inside the snap-fit ​​groove 25. When the elastic buckle 64 is inserted into the snap-fit ​​groove 25, its beveled surface engages with the beveled surface of the beveled protrusion 26, guiding the buckle to deform and slide in, engaging with the beveled protrusion 26. A pressing groove 641 is provided on the outer side of the vacuum cleaner housing 2, which allows the user to press the buckle to release the fastener and disassemble the outer shell 62. In addition, a mounting groove 621 is provided on the inner side of the outer shell 62, and a light shield 65 is placed in the mounting groove 621. One side of the light shield 65 contacts the surface of the control panel 63, and the other side abuts against the operation panel 66 provided on the outer side of the outer shell 62. The operation panel 66 is electrically connected to the control panel 63, and the user can control the start, stop and speed adjustment of the vacuum cleaner through the operation panel 66. Baffles 251 are also integrally formed on both sides of the snap-fit ​​groove 25 of the vacuum cleaner housing 2. The two ends of the baffles 251 are connected to the two ends of the inclined protrusion 26 to form a lateral limit on the elastic buckle 64.

[0034] The implementation principle of this application embodiment is as follows: First, by isolating the motor 3 within the vacuum cleaner housing 2, the end cap 1, and the battery pack 5 within the outer fixing frame 4, the motor 3 and battery pack 5 are placed in separate areas. This prevents vibrations from the motor 3 from being transmitted to the battery pack 5, which could cause the battery terminals to loosen. It also prevents heat from the battery pack 5 from affecting the motor 3's heat dissipation, thus solving the problem of mutual interference between components in traditional integrated installations. The electrical connection between the motor 3 and battery pack 5 is achieved through a control board 63, which is built into the connecting component 6. The connecting component 6 also serves to connect the fixing frame 4 to the housing, making the overall structure modular, reducing redundant parts, and improving assembly efficiency. The end cap 1 and housing are fixed together by positioning pins 24 and positioning slots 11, and bolts are used to ensure electrical connection. The coaxiality of the motor 3 after installation avoids suction loss caused by the misalignment of the suction port; the fixed frame 4 achieves precise positioning through the cooperation of the sliding groove 22, the protrusion 41, the limiting groove 42, and the limiting plate 21 to prevent misalignment during installation; the outer shell 62 achieves quick disassembly and assembly without tools through the cooperation of the elastic buckle 64, the snap-fit ​​groove 25, and the inclined protrusion 26, which facilitates maintenance of the control board 63; the control board 63 is horizontally limited by the positioning side plate 612 and vertically fixed by the limiting post 613; when connecting the fixed frame 4 and the vacuum cleaner shell 2, the electrical connector 27 at the end of the vacuum cleaner shell 2 is inserted into the connecting groove 611 of the connecting frame 61 and electrically connected to the control board 63, so that the battery pack 5 and the motor 3 form a short-path electrical connection, reducing the wire length, reducing line loss, and improving power supply efficiency.
