[0038] The service life of the side brush motor in the related art is relatively low. The inventor has found that the reason is that the side brush motor is exposed to the outside and is not sealed, that is, the sealing is poor. Dust and the like can easily enter the side brush motor, affecting the normal operation of the side brush motor and greatly reducing the service life of the side brush electrode.

[0039] The embodiment of the utility model provides a side brush motor protection cover, which includes a shell and a mounting column. The shell has a receiving cavity and an opening, so that the shell can be covered on the side brush motor, thereby reducing dust and the like from entering the side brush motor and ensuring the service life of the side brush motor. The shell is also provided with an avoidance gap, which is connected to the receiving cavity and extends to the opening to avoid the side brush motor or other structures, ensuring that the side brush motor and the like can work normally. The mounting column is arranged in the receiving cavity, and an installation hole is arranged at one end facing the opening, and the installation hole is configured to be connected to a connector to achieve the installation and fixation of the side brush motor protection cover and prevent the side brush motor protection cover from falling off.

[0040] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0041] See also Figures 1 to 5 The embodiment of the utility model provides a side brush motor protective cover 1, which can be applied to an unmanned sweeper. The unmanned sweeper includes a side brush structure and a side brush motor, and the side brush structure includes a bracket and a side brush arranged below the bracket. The bracket is also provided with a side brush motor, and a side brush motor protective cover 1 is provided on the side brush motor to protect the side brush motor and prevent the side brush motor from being completely exposed, thereby reducing dust and the like from entering the side brush motor and ensuring the service life of the side brush motor.

[0042] It can be understood that the number of side brush motor protection covers 1 matches the number of side brush motors, and the side brush motor protection covers 1 correspond to the side brush motors one by one, that is, each side brush motor is provided with a side brush motor protection cover 1, so that each side brush motor can be protected. Figure 1 As shown, two symmetrically distributed side brush motors are arranged on the bracket, and correspondingly, there are two side brush motor protection covers 1, and the two side brush motor protection covers 1 are also symmetrically distributed.

[0043] See also Figures 2 to 5The side brush motor protection cover 1 includes a shell 10 and a mounting post 20. The shell 10 is used to accommodate the side brush motor. The mounting post 20 is used to be fixedly connected to the bracket to ensure the stability of the side brush motor protection cover 1. The shell 10 has a receiving cavity, an opening, and an avoidance gap. The receiving cavity is used to protect other structures. The opening is arranged at one end of the receiving cavity and communicates with the receiving cavity. The opening allows the side brush motor to enter the receiving cavity, thereby covering the side brush motor. The avoidance gap is communicated with the receiving cavity and is connected to the opening to avoid the corresponding structure.

[0044] In some possible examples, the housing 10 includes an end plate and a side plate connected to the end plate. The end plate and the side plate are enclosed to form a receiving cavity. The side of the side plate facing away from the end plate is enclosed to form an opening, that is, the opening is opposite to the end plate. Specifically, one end of the side plate ( Figure 2 The upper end shown in the figure) is connected to the outer periphery of the end plate, and the side plate surrounds the entire periphery of the end plate. The other end of the side plate ( Figure 2 An opening is formed at the lower end as shown, so that the volume inside the accommodating cavity is larger.

[0045] The end plate can be a flat plate, and the side plate can be a curved plate to reduce the presence of sharp corners and avoid scratching the side brush motor, the side brush or the bracket. The end plate and the side plate can be an integrated structure to ensure the firmness of the connection between the end plate and the side plate. The side plate and the end plate are truncated or elliptical, that is, the cross-sectional size of the side plate gradually increases in the direction away from the end plate, so that the side plate is tilted outward, which is convenient for setting the mounting column 20, thereby achieving the fixation of the housing 10.

[0046] Some possible examples include Figures 2 to 5 As shown, the outer peripheral surface of the side plate is also provided with a heat dissipation hole 13, which penetrates the side plate and is spaced apart from the opening and the avoidance gap, that is, the heat dissipation hole 13 is not connected to the opening and the avoidance gap, and the heat dissipation hole 13 can also be spaced apart from the end plate. By providing the heat dissipation hole 13, air flow inside and outside the accommodating cavity can be achieved, thereby dissipating the heat of the side brush motor and preventing the side brush motor from overheating.

[0047] The heat dissipation hole 13 extends in a direction away from the end plate, for example, the heat dissipation hole 13 may be in a long strip shape, and the extension direction of the heat dissipation hole 13 is the direction from the end plate to the opening, for example, parallel to the generatrix direction of the truncated cone. A plurality of heat dissipation holes 13 are provided, and the plurality of heat dissipation holes 13 are arranged at intervals along the circumference of the side plate, for example, the plurality of heat dissipation holes 13 are arranged at equal intervals along the circumference of the side plate.

[0048] Continue reading Figures 2 to 5The mounting post 20 is disposed in the accommodating cavity. Specifically, the mounting post 20 is disposed on the inner wall of the accommodating cavity. Exemplarily, the mounting post 20 is an integral structure with the housing 10. A mounting hole 21 is disposed at one end of the mounting post 20 facing the opening. The orientation of the mounting hole 21 may be the same as that of the opening. The mounting hole 21 is configured to be connected to a connector.

[0049] In the example where the housing 10 includes an end plate and a side plate, the inner circumference of the side plate is connected to a mounting column 20, and a mounting hole 21 is formed on the surface of the mounting column 20 away from the end plate. Figure 3 As shown, a mounting hole 21 is provided at the bottom end of the mounting column 20. The mounting column 20 may be a cylinder, an elliptical column, a rectangular column, etc., and the mounting hole 21 may be a threaded hole, and the size and type of the mounting hole 21 are adapted to the connector.

[0050] Exemplarily, the connecting piece may be a bolt, for example, a flange bolt of M6×12. The bracket is provided with a threaded hole or a through hole, and the connecting piece is passed through the threaded hole or the through hole of the bracket and connected to the threaded hole of the mounting column 20, so as to fix the housing 10 relative to the bracket. During assembly, the side brush motor is first installed on the bracket, and then the side brush motor protective cover 1 is buckled on the side brush motor, and then the side brush motor protective cover 1 and the bracket are fixed by the connecting piece.

[0051] Continue reading Figures 2 to 5 The housing 10 is also provided with an escape notch, which is connected to the accommodating cavity and extends to the opening. By providing the escape notch, the circuit of the side brush motor can be externally connected, and at the same time, other structures can be avoided, such as the nozzle of the side brush. The escape notch runs through the housing 10 and extends to the opening, and the avoidance notch and the corresponding structure can be matched from one side of the opening.

[0052] In the example where the housing 10 includes an end plate and a side plate, a relief notch is provided on the outer circumference of the side plate, the relief notch penetrates the side plate, and the end of the relief notch away from the end plate extends to the opening. The relief notch is spaced from the end plate, which can prevent the relief notch from being too large to cause more dust to enter, and can also ensure the strength and stability of the side plate.

[0053] In some possible examples, the avoidance gap includes a first avoidance gap 11 and a second avoidance gap 12 spaced apart, and the first avoidance gap 11 and the second avoidance gap 12 both extend to the opening. Among them, a routing and / or rotating structure may be provided in the first avoidance gap 11, and the shape of the first avoidance gap 11 may be rectangular, etc. A nozzle with a side brush may be provided in the second avoidance gap 12, and the shape of the second avoidance gap 12 may be semicircular or semi-elliptical.

[0054] Among them, at least one mounting column 20 is arranged between the first escape opening 11 and the second escape opening 12, and the mounting column 20 and the housing 10 are an integral structure. In this way, by arranging the mounting column 20 between the first escape opening 11 and the second escape opening 12, the mounting column 20 can increase the strength of the housing 10 located between the first escape opening 11 and the second escape opening 12, thereby preventing the housing 10 from being deformed at this location.

[0055] Some possible examples include Figure 5 As shown, three mounting posts 20 are provided, and the three mounting posts 20 are distributed at intervals, for example, at equal intervals. One mounting post 20 is provided on the side where the first escape opening 11 and the second escape opening 12 are adjacent to each other, and two mounting posts 20 are provided on the side where the first escape opening 11 and the second escape opening 12 are away from each other. The side where the first escape opening 11 and the second escape opening 12 are adjacent to each other refers to the side where the first escape opening 11 and the second escape opening 12 are closer to each other, and the side where the first escape opening 11 and the second escape opening 12 are away from each other refers to the side where the first escape opening 11 and the second escape opening 12 are farther from each other.

[0056] Continue reading Figures 2 to 5 The side brush motor protection cover 1 also includes a first enclosure 31, a second enclosure 32, and a connecting enclosure 33 connecting the first enclosure 31 and the second enclosure 32. The first enclosure 31, the second enclosure 32 and the connecting enclosure 33 are arranged on one side of the opening to support the shell 10, increase the strength of the shell 10, and reduce the deformation of the shell 10.

[0057] The first enclosure 31 is arranged at the periphery of the first avoidance opening 11, that is, the first enclosure 31 surrounds the first avoidance opening 11. The second enclosure 32 is arranged at the periphery of the second avoidance opening 12, that is, the second enclosure 32 surrounds the second avoidance opening 12. The connecting enclosure 33 is arranged at the periphery of the opening, that is, the connecting enclosure 33 surrounds the opening, and the connecting enclosure 33 also connects the corresponding ends of the first enclosure 31 and the second enclosure 32. The connecting enclosure 33 connects the first enclosure 31 and the second enclosure 32, so that the connecting enclosure 33, the first enclosure 31 and the second enclosure 32 can surround the shell 10 for a full circle.

[0058] In some possible examples, the first enclosure 31 surrounds the entire periphery of the first avoidance opening 11, the second enclosure 32 surrounds the entire periphery of the second avoidance opening 12, and the connecting enclosure surrounds the entire periphery of the opening. Wherein, along the circumference of the first avoidance opening 11, the width of the first enclosure 31 is not uniform, for example, the width of the first enclosure 31 adjacent to the second avoidance opening 12 and the portion of the first enclosure 31 away from the opening is greater than the width of the portion of the first enclosure 31 away from the second avoidance opening 12, so as to adapt to the required avoidance structure.

[0059] The connecting panel 33, the first panel 31 and the second panel 32 can be an integral structure. Further, the connecting panel 33, the first panel 31, the second panel 32 and the shell 10 are an integral structure. For example, the connecting panel 33, the first panel 31, the second panel 32, the shell 10, the side panels and the end panels are an integral structure. There is no need to set connecting parts between these structures, which can simplify the structure in the side brush motor protection cover 1.

[0060] In some possible examples, the connecting enclosure 33 includes a first segment and a second segment. The first segment is disposed at one end of the first enclosure 31 and the second enclosure 32 adjacent to each other, that is, both ends of the first segment are respectively connected to one end of the first enclosure 31 and the second enclosure 32 adjacent to each other. The second segment is disposed at one end of the first enclosure 31 and the second enclosure 32 away from each other, that is, both ends of the second segment are respectively connected to one end of the first enclosure 31 and the second enclosure 32 away from each other.

[0061] The first segment and the second segment are arranged on one side of the opening of the housing 10 and connected to the first enclosure 31 and the second enclosure 32. On the one hand, the structural strength of the side brush motor protection cover 1 can be increased, and on the other hand, support can be provided for the side brush motor protection cover 1 for easy installation. Specifically, the second segment can be a flat plate, which is opposite to the bracket, and the side brush motor protection cover 1 can be placed on the bracket by the second segment. The first segment can also be a flat plate, which is usually shorter in length.

[0062] In order to further improve the overall structural strength of the side brush motor protection cover 1, the first enclosure 31, the second enclosure 32 and the connecting enclosure 33 are all provided with flanges 40 at one end away from the accommodating cavity. For example, the flanges 40 surround the entire circumference of the shell 10, or the flanges 40 are discontinuous along the circumference of the shell 10, for example, the portion of the first enclosure 31 away from the second enclosure 32 is not provided with flanges. Figures 2 to 5 As shown, the flange 40 is located on the side of the first enclosure 31, the second enclosure 32 and the connecting enclosure 33 away from the side plate, and extends in a direction away from the end plate.

[0063] The flange 40 connected to the first enclosure 31 can be perpendicular to the first enclosure 31, the flange 40 connected to the second enclosure 32 can be perpendicular to the second enclosure 32, and the flange 40 connected to the connecting enclosure 33 can be perpendicular to the connecting enclosure 33. The flange 40 and the first enclosure 31, the second enclosure 32 and the connecting enclosure 33 can be an integral structure. For example, the entire side brush motor protection cover 1 is made of plastic, which is integrally formed by injection molding and has good insulation performance. Of course, the material of the side brush motor protection cover 1 is not limited.

[0064] In summary, the side brush motor protection cover 1 in the embodiment of the utility model includes a shell 10 and a mounting post 20. The shell 10 has a accommodating cavity and an opening arranged at one end of the accommodating cavity, so that the cover is arranged on the side brush motor to provide protection for the side brush motor and prevent the side brush motor from being completely exposed, thereby reducing dust and the like from entering the side brush motor and ensuring the service life of the side brush motor. The shell 10 is also provided with an avoidance gap, which is connected to the accommodating cavity and extends to the opening to avoid the side brush motor or other structures to ensure that the side brush motor and the like can work normally. The mounting post 20 is arranged in the accommodating cavity, and an installation hole 21 is arranged at one end facing the opening. The installation hole 21 is configured to be connected to a connector to achieve the installation and fixation of the side brush motor protection cover 1 and prevent the side brush motor protection cover 1 from falling off.
