Description

Technical Field

[0001] This application relates to the field of battery sealing technology, and in particular to a battery sealing structure and cleaning equipment. Background Technology

[0002] In related technologies, the battery sealing structure of cleaning equipment includes a battery compartment, a battery, and a battery cover. The battery is housed inside the battery compartment, and the battery cover seals the battery compartment. A sealing strip is provided between the battery cover and the battery compartment to achieve a seal for the battery compartment. However, the sealing strip must be inserted bit by bit into the annular groove of the battery cover, resulting in a long assembly time for the battery sealing structure and low assembly efficiency. Utility Model Content

[0003] In view of this, embodiments of this application provide a battery sealing structure and cleaning equipment to solve the problem of long assembly time for battery sealing structures.

[0004] The first aspect of this application discloses a battery sealing structure, including a battery compartment, a battery cover, and a seal, wherein the battery compartment has an opening for the battery to enter and exit, and the edge of the seal is pressed between the battery cover and the battery compartment and the seal covers the opening.

[0005] The beneficial effects of the battery sealing structure provided in this application are as follows: By sealing the compartment opening with a seal and pressing the seal between the battery cover and the battery compartment, not only can the battery compartment be sealed, but the seal can also cushion the battery inside the compartment when subjected to vibration, improving battery safety. Compared to the sealing strips in the prior art, the seal in this application can be quickly placed between the battery cover and the battery compartment, which is beneficial for installing the seal between the battery cover and the battery compartment, saving assembly time and improving assembly efficiency.

[0006] In some embodiments, the seal is a sealing sheet, the edge of which is pressed between the battery cover and the battery compartment.

[0007] The advantages of adopting the above technical solution are: the sealing sheet is relatively small in size, which can save material costs and reduce the space occupied, which is conducive to the arrangement of other components.

[0008] In some embodiments, a sealing ring rib is provided at the opening of the battery compartment and / or on the battery cover, and the sealing ring rib abuts against one side of the sealing sheet in the thickness direction.

[0009] The beneficial effects of adopting the above technical solution are as follows: by having the sealing ring rib abut against one side of the sealing sheet in its thickness direction, the deformation of the edge of the sealing sheet can be increased, which is more conducive to improving the sealing performance.

[0010] In some embodiments, the seal is fixed to the side of the battery cover facing the battery compartment.

[0011] The beneficial effects of adopting the above technical solution are as follows: Since the sealing element is pre-fixed on the side of the battery cover facing the battery compartment, the sealing element will not move relative to the battery cover when the battery compartment and the battery cover are fixedly connected. This helps to press the sealing element between the battery compartment and the battery cover, thereby improving assembly efficiency.

[0012] In some embodiments, the seal is adhesively fixed to the side of the battery cover facing the battery compartment.

[0013] The beneficial effects of adopting the above technical solution are: by bonding and fixing the seal to the side of the battery cover facing the battery compartment, the fixing of the seal to the battery cover is simpler and faster.

[0014] In some embodiments, the battery cover has a positioning portion on the side facing the battery compartment for positioning the seal.

[0015] The beneficial effects of adopting the above technical solution are: the positioning part can position the sealing element to ensure the accuracy of the sealing element's position, thereby enabling better sealing of the hopper opening.

[0016] In some embodiments, the positioning portion is a positioning protrusion protruding from the side of the battery cover facing the battery compartment.

[0017] The beneficial effects of adopting the above technical solution are: except for the position of the positioning protrusion, the thickness of other areas on the battery cover can be designed to be thinner, which helps to reduce the weight of the battery cover and thus facilitates lightweight design.

[0018] In some embodiments, the positioning protrusion is an annular protrusion that forms a groove with an opening facing the battery compartment, and the seal is located within the groove.

[0019] The beneficial effects of adopting the above technical solution are as follows: In the direction parallel to the seal, the annular protrusion can limit the edge of the seal, preventing the seal from deforming in the direction parallel to the seal when it is under pressure, thereby ensuring the sealing performance.

[0020] In some embodiments, the sealant is sealing foam.

[0021] The beneficial effects of adopting the above technical solution are that the sealing foam is not only waterproof, but also dustproof, chemically resistant, and resistant to high and low temperatures. Therefore, it can improve the service life of the sealing sheet and reduce the number of times the sealing sheet needs to be replaced.

[0022] In some embodiments, the sealing foam is waterproof and fireproof silicone.

[0023] In some embodiments, the battery compartment has a battery cavity for installing batteries and a wiring cavity for routing cables, the wiring cavity being located on one side of the battery cavity in a direction parallel to the sealing sheet.

[0024] The beneficial effects of adopting the above technical solution are as follows: When the battery sealing structure is applied to the cleaning equipment, under normal working conditions, the direction parallel to the sealing sheet is horizontal, that is, the wiring cavity is located on one side of the battery cavity in the horizontal direction. In this way, the space occupied in the vertical direction can be reduced, thereby reducing the vertical size of the cleaning equipment.

[0025] In some embodiments, the sealing sheet is provided with a positioning structure, which is used to position the sealing sheet during the placement and removal of the sealing sheet.

[0026] In some embodiments, the positioning structure includes a plurality of positioning holes for positioning the sealing sheet when the robotic arm grasps the sealing sheet.

[0027] The beneficial effects of adopting the above technical solution are: when the robotic arm grasps the sealing sheet, the sealing sheet is positioned by multiple positioning holes to ensure the accuracy of the robotic arm placing the sealing sheet on the battery cover after grasping it.

[0028] In some embodiments, the battery cover is fixedly connected to the battery compartment by threaded fasteners.

[0029] The beneficial effects of adopting the above technical solution are as follows: the battery cover is fixedly connected to the battery compartment by threaded fasteners, which not only facilitates the installation and replacement of the battery, but also ensures the stability of the fixed connection between the battery cover and the battery compartment.

[0030] A second aspect of this application provides a cleaning device comprising a main unit housing and a battery sealing structure as described in the first aspect, the battery sealing structure being installed within the main unit housing.

[0031] The cleaning device employs any one or more embodiments of the battery sealing structure described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.

[0057] An embodiment of the first aspect of this application provides a battery sealing structure that can be applied to devices that require battery power, such as cleaning equipment.

[0058] Please refer to Figures 1 to 3 The battery sealing structure 10 includes a battery compartment 11, a battery cover 12, and a seal 13. The battery compartment 11 has an opening 115 for the battery 14 to enter and exit. The battery cover 12 is fixedly connected to the battery compartment 11. The seal 13 covers the opening 115 and is pressed between the battery cover 12 and the battery compartment 11.

[0059] The battery compartment 11 is used to accommodate the battery 14, which is inserted into the battery compartment 11 through the opening 115. The shape of the battery compartment 11 is not limited in this application, as long as it can ensure that the battery 14 will not move when installed in the battery compartment 11.

[0060] Please refer to Figure 6 When the battery sealing structure 10 is applied to the cleaning device 100, the battery compartment 11 is fixed inside the main housing 20 of the cleaning device 100.

[0061] The method of fixing the battery cover 12 to the battery compartment 11 is not limited in this application. For example, the battery cover 12 can be fixedly connected to the battery compartment 11 by a threaded fastener, or the battery cover 12 can be fixedly connected to the battery compartment 11 by a snap-fit ​​structure.

[0062] The seal 13 is pressed between the battery cover 12 and the battery compartment 11. This can be understood as the seal 13 being pressed between the battery cover 12 and the battery compartment 11 when the battery cover 12 and the battery compartment 11 are fixedly connected, so that the seal 13 cannot move.

[0063] The seal 13 covers the opening 115, that is, the projection of the opening 115 on the battery cover 12 is within the projection of the seal 13 on the battery cover 12.

[0064] The beneficial effects of the battery sealing structure 10 provided in this application embodiment are as follows: By sealing the opening 115 with the sealing element 13 and pressing the sealing element 13 between the battery cover 12 and the battery compartment 11, not only can the battery compartment 11 be sealed, but the sealing element 13 can also buffer the battery 14 inside the battery compartment 11 when subjected to vibration, thereby improving the safety of the battery 14. Compared with the sealing strip in the prior art, the sealing element 13 in this application can be quickly placed between the battery cover 12 and the battery compartment 11, which is beneficial for installing the sealing element 13 between the battery cover 12 and the battery compartment 11, saving assembly time and improving assembly efficiency.

[0065] In some embodiments, the seal 13 is a sealing sheet, the edge of which is pressed between the battery cover 12 and the battery compartment 11.

[0066] Understandably, in the direction parallel to the sealing strip, the size of the sealing strip is slightly larger than the size of the opening 115. This allows for a relatively smaller sealing strip size, saving material costs and reducing space requirements, which is beneficial for the arrangement of other components. The projection direction is... Figure 2 The X direction in the equation.

[0067] Multiple heat dissipation holes can be provided on the sealing sheet corresponding to the position of the battery 14. That is, the heat dissipation holes are located inside the compartment opening 115 in a direction parallel to the sealing sheet. This design facilitates heat dissipation of the battery 14 without affecting the seal of the battery compartment 11. In this case, the sealing sheet covers part of the compartment opening 115. Of course, if the battery 14 has good heat dissipation, the sealing sheet may not have heat dissipation holes. In this case, the sealing sheet covers the entire compartment opening 115.

[0068] The thickness of the sealing sheet is not limited in this application, as long as it can meet the requirements of sealing the battery compartment 11 and cushioning the battery 14.

[0069] It is understandable that the sealing sheet can be of uniform thickness; or, the edge thickness of the sealing sheet can be greater than, equal to or less than the middle thickness of the sealing sheet.

[0070] Please refer to Figures 3 to 5 In some embodiments, a sealing ring rib 111 is provided at the opening 115 of the battery compartment 11, and the sealing ring rib 111 abuts against one side of the sealing sheet in the thickness direction. The thickness direction of the sealing sheet is... Figure 2 The X direction in the equation.

[0071] It is understood that the sealing ring rib 111 can be integrally formed with the battery compartment 11; or, the sealing ring rib 111 can also be fixed to the side of the battery compartment 11 facing the battery cover 12 by means of bonding, fusion, welding or other methods.

[0072] The projection of the sealing ring rib 111 onto the battery cover 12 lies within the projection of the sealing sheet onto the battery cover 12. Understandably, in the direction parallel to the sealing sheet, the size of the sealing sheet is larger than the size of the sealing ring rib 111. For example, the sealing ring rib 111 abuts against the edge of the sealing sheet, meaning the size of the sealing sheet can be slightly larger than the size of the sealing ring rib 111. This results in a relatively small size for the sealing sheet, saving material costs and reducing space requirements, which is beneficial for the arrangement of other components.

[0073] Based on the above technical solution, by having the sealing ring rib 111 abut against one side of the sealing sheet in its thickness direction, the deformation of the edge of the sealing sheet can be increased, so that its compression reaches more than 40%, which is more conducive to improving the sealing performance.

[0074] In other embodiments, the sealing ring rib 111 can be provided on the battery cover 12, and the sealing ring rib 111 abuts against one side of the sealing sheet in its thickness direction. Alternatively, both the battery compartment 11 and the battery cover 12 can be provided with sealing ring ribs 111, and the two sealing ring ribs 111 abut against opposite sides of the sealing sheet in its thickness direction. Alternatively, neither the battery compartment 11 nor the battery cover 12 can be provided with sealing ring ribs 111, and the side of the battery compartment 11 facing the battery cover 12 and the side of the battery cover 12 facing the battery compartment 11 can be used to press the sealing sheet against opposite sides in its thickness direction, causing the sealing sheet to deform and achieve a seal.

[0075] Please refer to Figure 2 and Figure 3 In some embodiments, the seal 13 is fixed to the side of the battery cover 12 facing the battery compartment 11.

[0076] Based on the above technical solution, since the sealing element 13 is pre-fixed on the side of the battery cover 12 facing the battery compartment 11, when the battery compartment 11 and the battery cover 12 are fixedly connected, the sealing element 13 will not move relative to the battery cover 12, which is beneficial for the sealing element 13 to be pressed between the battery compartment 11 and the battery cover 12, thereby improving the assembly efficiency.

[0077] In other embodiments, the seal 13 may not be pre-fixed to the battery cover 12. When the battery compartment 11 and the battery cover 12 are fixedly connected, the seal 13 is placed on the battery cover 12 at the position corresponding to the battery compartment 11, and then the battery compartment 11 and the battery cover 12 are fixedly connected to press the seal 13 between the battery compartment 11 and the battery cover 12.

[0078] Please refer to Figure 2 and Figure 3 In some embodiments, the seal 13 is bonded and fixed to the side of the battery cover 12 facing the battery compartment 11.

[0079] For example, the seal 13 is provided with adhesive backing, and the seal 13 is bonded and fixed to the side of the battery cover 12 facing the battery compartment 11 by the adhesive backing. Of course, the seal 13 may not be provided with adhesive backing, but adhesive may be applied separately to the seal 13 and / or the battery cover 12 to bond and fix the seal 13 to the side of the battery cover 12 facing the battery compartment 11.

[0080] Based on the above technical solution, by bonding and fixing the sealing element 13 to the side of the battery cover 12 facing the battery compartment 11, the fixing of the sealing element 13 to the battery cover 12 is relatively simple and quick.

[0081] In other embodiments, the seal 13 may also be fixed to the side of the battery cover 12 facing the battery compartment 11 by fasteners; or, the seal 13 may also be fixed to the side of the battery cover 12 facing the battery compartment 11 by interference fit.

[0082] In some embodiments, the battery cover 12 is provided with a positioning part 122 for positioning the seal 13 on the side facing the battery compartment 11.

[0083] Based on the above technical solution, the positioning part 122 can position the sealing element 13 to ensure the accuracy of the position of the sealing element 13, thereby better sealing the opening 115.

[0084] Please refer to Figure 2 and Figure 4 In some embodiments, the positioning part 122 is a positioning protrusion 1221 that protrudes from the side of the battery cover 12 facing the battery compartment 11.

[0085] It is understandable that when the thickness of the edge of the seal 13 is greater than the protrusion height of the positioning protrusion 1221, a sealing ring rib 111 can be provided at the opening 115 of the battery compartment 11, or it can be omitted. That is, regardless of whether a sealing ring rib 111 is provided at the opening 115 of the battery compartment 11, the edge of the seal 13 can be compressed. When the thickness of the edge of the seal 13 is less than or equal to the protrusion height of the positioning protrusion 1221, a sealing ring rib 111 needs to be provided at the opening 115 of the battery compartment 11 to ensure that the edge of the seal 13 is compressed. When a sealing ring rib 111 is provided at the opening 115 of the battery compartment 11, the positioning protrusion 1221 is located outside the sealing ring rib 111 in the direction parallel to the seal 13.

[0086] It is understood that the positioning protrusion 1221 can be integrally formed with the battery cover 12; or, the positioning protrusion 1221 can also be fixed to the side of the battery cover 12 facing the battery compartment 11 by means of bonding, fusion, welding or other methods.

[0087] Based on the above technical solution, except for the position of the positioning protrusion 1221, the thickness of other areas on the battery cover 12 can be designed to be thinner, which is beneficial to reduce the weight of the battery cover 12 and thus facilitates lightweight design.

[0088] In some embodiments, the positioning protrusion 1221 is an annular protrusion, and the positioning protrusion 1221 forms a groove 121 with an opening facing the battery compartment 11, and the seal 13 is located in the groove 121.

[0089] For example, the shape of the groove 121 is adapted to the shape of the seal 13.

[0090] Based on the above technical solution, in the direction parallel to the seal 13, the annular protrusion can limit the edge of the seal 13, preventing the seal 13 from deforming in the direction parallel to the seal 13 when it is under pressure, thereby ensuring the sealing performance.

[0091] In other embodiments, the positioning protrusion 1221 may be a C-shaped protrusion; or, the positioning protrusion 1221 may include a plurality of positioning protrusions arranged around the seal 13.

[0092] In some embodiments, the positioning portion 122 may also be a positioning recess recessed on the side of the battery cover 12 facing the battery compartment 11, that is, the positioning recess is formed by a recess in the surface of the battery cover 12.

[0093] In some embodiments, the positioning part 122 is a positioning line provided on the side of the battery cover 12 facing the battery compartment 11, and the edge of the sealing member 13 is placed along the positioning line on the side of the battery cover 12 facing the battery compartment 11. Exemplarily, the positioning line is a positioning loop line, and the positioning loop line is adapted to the edge contour of the sealing member 13.

[0094] In some embodiments, the seal 13 is a sealing foam.

[0095] It is understandable that sealing foam can be made of rubber, such as natural rubber, nitrile rubber, neoprene rubber, EPDM rubber, fluororubber, etc.; or, sealing foam can be made of plastic, such as polyethylene, polypropylene, etc.; or, sealing foam can also be made of silicone, such as waterproof and fireproof silicone, which can achieve a V0 fire resistance rating while ensuring sealing performance.

[0096] Based on the above technical solution, the sealing foam is not only waterproof, but also has the advantages of dustproof, chemical corrosion resistance, and high and low temperature resistance. Therefore, it can improve the service life of the sealing element 13 and reduce the number of times the sealing element 13 is replaced.

[0097] Please refer to Figure 3 , Figure 5 and Figure 6In some embodiments, the battery compartment 11 has a battery cavity 112 for mounting the battery 14 and a wiring cavity 113 for wiring, the wiring cavity 113 being located on one side of the battery cavity 112 in a direction parallel to the sealing sheet.

[0098] The wiring cavity 113 is connected to the battery cavity 112, and the wire harness connected to the battery 14 is led out through the wiring cavity 113. The size of the wiring cavity 113 is smaller than the size of the battery cavity 112.

[0099] For example, the battery compartment 11 is also provided with a cable outlet 116, which is located at the end of the cable routing cavity 113 away from the battery cover 12. That is, the wires entering the cable routing cavity 113 are led out through the cable outlet 116. A sealing sleeve 15 is provided inside the cable outlet 116 to ensure the sealing of the cable outlet 116.

[0100] For example, the battery 14 is shaped like a cuboid or a cube, and the battery cavity 112 is shaped like a rectangle. Of course, the battery 14 and the battery cavity 112 can also be other shapes, for example, the battery 14 is shaped like a cylinder, and the battery cavity 112 is shaped like a circle.

[0101] For example, the wiring cavity 113 is a right trapezoid. Of course, the wiring cavity 113 can also be other shapes, such as rectangle, semicircle, isosceles trapezoid, etc.

[0102] Based on the above technical solution, when the battery sealing structure 10 is applied to the cleaning equipment 100, under normal working conditions, the direction parallel to the sealing sheet is horizontal, that is, the wiring cavity 113 is located on one side of the battery cavity 112 in the horizontal direction. In this way, the space occupied in the vertical direction can be reduced, thereby reducing the vertical size of the cleaning equipment 100.

[0103] In other embodiments, the wiring cavity 113 may be omitted, and the wire outlet 116 may be located at the end of the battery cavity 112 away from the battery cover 12, that is, the wire harness connected to the battery 14 may be directly led out from the wire outlet 116.

[0104] Please refer to Figure 2 In some embodiments, the sealing sheet is provided with a positioning structure, which is used to position the sealing sheet during the removal and placement of the sealing sheet.

[0105] For example, the positioning structure includes a plurality of positioning holes 131 for positioning the sealing sheet when the robotic arm grasps the sealing sheet.

[0106] For example, the positioning holes 131 can be two, three, four or more.

[0107] When there are three positioning holes 131, the three positioning holes 131 are arranged in a triangular shape.

[0108] For example, the positioning hole 131 is circular in shape.

[0109] The robotic arm is equipped with a positioning pin that engages with the positioning hole 131 and an adsorption component for adsorbing the sealing sheet. When gripping the sealing sheet, the positioning pin on the robotic arm is inserted into the positioning hole 131 on the sealing sheet, and then the adsorption component adsorbs the sealing sheet, thereby moving the sealing sheet and placing it in the groove 121 of the battery cover 12 to ensure the accuracy of the sealing sheet placement on the battery cover 12.

[0110] Please refer to Figure 2 and Figure 5 In some embodiments, the battery cover 12 is fixedly connected to the battery compartment 11 by threaded fasteners.

[0111] It is understandable that threaded fasteners can be screws, bolts, etc.

[0112] For example, the battery compartment 11 is provided with a threaded hole 114, and the battery cover 12 is provided with a through hole 123. The threaded fastener passes through the through hole 123 and is screwed into the threaded hole 114 to achieve a fixed connection between the battery cover 12 and the battery compartment 11. The threaded hole 114 is located outside the sealing ring rib 111, and the through hole 123 is located outside the positioning protrusion 1221.

[0113] The battery compartment 11 has multiple threaded holes 114, and the battery cover 12 has multiple through holes 123 to ensure the stability of the fixed connection between the battery cover 12 and the battery compartment 11.

[0114] Of course, the threaded hole 114 can be provided on the battery cover 12, and the through hole 123 can be provided on the battery compartment 11.

[0115] Based on the above technical solution, the battery cover 12 is fixedly connected to the battery compartment 11 by threaded fasteners, which not only facilitates the installation and replacement of the battery 14, but also ensures the stability of the fixed connection between the battery cover 12 and the battery compartment 11.

[0116] Please refer to Figure 6 The second aspect of this application discloses a cleaning device 100, which includes a main unit housing 20 and a battery sealing structure 10 as described in the first aspect, the battery sealing structure 10 being installed inside the main unit housing 20. The cleaning device 100 may be a robotic vacuum cleaner.

[0117] For example, during assembly, the battery compartment 11 can be fixed inside the main unit housing 20 first, then the battery 14 can be installed inside the battery compartment 11, then the sealing sheet can be installed on the battery cover 12, and finally the battery cover 12 can be fixedly connected to the battery compartment 11 to press the battery 14 into the battery compartment 11.
