[0046] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0047] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0049] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0050] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0051] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0052] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0053] See Figures 1 to 5 This application provides a snowplow. For ease of explanation, based on the general operating conditions of the snowplow's travel direction, the following settings are provided: Figure 1 The snowplow is shown in the front-back, up-down, and left-right directions. The snowplow includes a main unit 110 and an operating component 120. The main unit 110 has wheels 130 on its left and right sides for supporting its movement on the ground. The operating component 120 is located at the rear of the main unit 110 and connected to it. The operating component 120 includes a connecting rod and a handle. The connecting rod connects the handle to the main unit 110, and the handle is for user operation.

[0054] Snowplows also include a snowplow system, a power system, a transmission system, and an energy system. The transmission system is used to transfer kinetic energy from the power system to the snowplow system, and the energy system is used to supply energy to the power system.

[0055] The snow removal system includes a snow removal assembly 140 and a snow inlet housing 150. The snow removal assembly 140 includes a rotating shaft 141 and a snow removal paddle 142 disposed on the rotating shaft 141. The rotating shaft 141 is configured to rotate about a first axis 1411. The snow inlet housing 150 houses at least a portion of the snow removal assembly 140. The snow inlet housing 150 has a front opening 151 for snow entry, which is understood to be located at the front end of the snow inlet housing 150.

[0056] The snow inlet housing 150 has a first accommodating space 152 and a second accommodating space communicating with the first accommodating space 152. The rotating shaft 141 and at least part of the snow sweeping paddle 142 are located in the first accommodating space 152. The first accommodating space 152 is recessed from front to back. The second accommodating space is located at the rear end of the first accommodating space 152. The front opening 151 is the snow inlet located at the front end of the first accommodating space 152.

[0057] Specifically, the snow inlet housing 150 includes a top plate 153, a back plate 154, and side plates 155 disposed on the left and right sides of the back plate 154. The top plate 153, back plate 154, and side plates 155 form a first receiving space 152. The two ends of the rotating shaft 141 are connected to the side plates 155. The back plate 154 has an arcuate portion for accommodating the snowplow 142. The first receiving space 152 has a top wall, a rear wall, and side walls. Exemplarily, the top wall is a horizontal surface or a stepped surface, at least a portion of the rear wall is a plane, at least a portion of the rear wall is a curved surface, and the side walls are vertical surfaces.

[0058] In some embodiments, the snow inlet housing 150 is a one-piece molded structure with the front opening 151 facing forward. The wall thickness of the snow inlet housing 150 is greater than or equal to 1.2 mm and less than or equal to 3 mm. In some embodiments, the snow inlet housing 150 is formed by connecting multiple independently molded plates. The wall thickness of the side plate 155 is greater than the wall thickness of the back plate 154, the wall thickness of the side plate 155 is greater than or equal to 1.5 mm and less than or equal to 2 mm, and the wall thickness of the back plate 154 is greater than or equal to 1.2 mm and less than or equal to 1.8 mm. In some embodiments, the snow inlet housing 150 is a metal structure. In some embodiments, the snow inlet housing 150 is made of non-metallic material. In some embodiments, the snow inlet housing 150 is assembled from metallic and non-metallic materials.

[0059] As described above, the snow inlet housing 150 includes a back plate 154 and side plates 155 disposed on the left and right sides of the back plate 154. The side plates 155 form a first projection on the second plane 102, and the snow sweeping assembly 140 forms a second projection on the second plane 102. The ratio of the area S1 of the first projection to the overlapping area S2 of the first projection and the second projection is greater than or equal to 1 and less than or equal to 1.6. The second plane 102 is substantially perpendicular to the first axis 1411.

[0060] In some embodiments, the ratio of the area S1 of the first projection to the overlapping area S2 of the first and second projections is greater than or equal to 1.2 and less than or equal to 1.5. In some embodiments, the ratio of the area S1 of the first projection to the overlapping area S2 of the first and second projections is equal to 1, 1.1, 1.26, 1.36, 1.4, or 1.5.

[0061] The height difference between the center of gravity of the snow inlet housing 150 and the first axis 1411 in the vertical direction is greater than or equal to 90 mm and less than or equal to 110 mm to ensure stability of the center of gravity. In some embodiments, the height difference between the center of gravity of the snow inlet housing 150 and the first axis 1411 in the vertical direction is greater than or equal to 95 mm and less than or equal to 105 mm. In some embodiments, the height difference between the center of gravity of the snow inlet housing 150 and the first axis 1411 in the vertical direction is equal to 90 mm, 92 mm, 95 mm, 98 mm, 100 mm, 102 mm, 105 mm, 108 mm or 110 mm.

[0062] The distance between the projection of the center of gravity of the snow inlet housing 150 onto the first plane 101 and the projection of the first axis 1411 onto the first plane 101 is greater than or equal to 10 mm and less than or equal to 20 mm; the first plane 101 is substantially parallel to the ground plane. This ensures that the center of gravity is relatively close to the first axis 1411, guaranteeing stability. In some embodiments, the distance between the projection of the center of gravity of the snow inlet housing 150 onto the first plane 101 and the projection of the first axis 1411 onto the first plane 101 is greater than or equal to 12 mm and less than or equal to 18 mm. In some embodiments, the distance between the projection of the center of gravity of the snow inlet housing 150 onto the first plane 101 and the projection of the first axis 1411 onto the first plane 101 is equal to 12 mm, 13 mm, 14 mm, 15 mm, 15.5 mm, 16 mm, 18 mm, or 20 mm.

[0063] See Figure 4 The distance L1 between the projection of the highest point 1511 of the front opening 151 onto the first plane 101 and the projection of the first axis 1411 onto the first plane 101 is less than or equal to 20 mm; the first plane 101 is substantially parallel to the ground plane. That is, the highest point 1511 of the front opening 151 is relatively close to the first axis 1411 in the front-rear direction, and the highest point 1511 of the front opening 151 is positioned relatively far back, preventing the highest point 1511 of the front opening 151 from contacting snow, reducing resistance during forward movement, and also preventing snow from accumulating on the top of the snow inlet housing 150. For example, the distance L1 between the projection of the highest point 1511 of the front opening 151 onto the first plane 101 and the projection of the first axis 1411 onto the first plane 101 is equal to 20 mm, 18 mm, 15 mm, 12 mm, 10 mm, 8 mm, 5 mm, 3 mm, or 0 mm.

[0064] In some embodiments, the distance L1 between the projection of the highest point 1511 of the front opening 151 onto the first plane 101 and the projection of the first axis 1411 onto the first plane 101 is greater than 0 and less than or equal to 20 mm. The projection of the highest point 1511 of the front opening 151 onto the first plane 101 is located in front of or behind the projection of the first axis 1411 onto the first plane 101.

[0065] In some embodiments, the projection of the highest point 1511 of the front opening 151 onto the first plane 101 overlaps with the projection of the first axis 1411 onto the first plane 101. That is, the distance L1 between the projection of the highest point 1511 of the front opening 151 onto the first plane 101 and the projection of the first axis 1411 onto the first plane 101 is equal to 0 mm. In other words, the highest point 1511 of the front opening 151 is located directly above the first axis 1411.

[0066] See Figure 5The front opening 151 includes an inclined portion 1512, the angle α between the inclined portion 1512 and the first plane 101 being greater than or equal to 30 degrees and less than or equal to 90 degrees. In some embodiments, the front opening 151 includes an inclined portion 1512, the angle α between the inclined portion 1512 and the first plane 101 being greater than or equal to 45 degrees and less than or equal to 60 degrees. In some embodiments, the front opening 151 includes an inclined portion 1512, the angle α between the inclined portion 1512 and the first plane 101 being equal to 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, or 90 degrees.

[0067] The inclined portion 1512 is located at the upper end of the front opening 151 and extends upwards and tilts from front to back. The setting of the inclined portion 1512 makes the top of the front opening 151 more rearward, further preventing the highest point 1511 of the front opening 151 from contacting the snow and reducing resistance during the forward movement.

[0068] The projected length L2 of the inclined portion 1512 on the first plane 101 is greater than or equal to 0 and less than or equal to 0.5*D, where D is the diameter of the snowplow 142, so that the inclined portion 1512 occupies less space in the front-to-back direction. In some embodiments, the projected length L2 of the inclined portion 1512 on the first plane 101 is greater than or equal to 0 and less than or equal to 0.2*D. For example, the diameter D of the snowplow 142 is greater than or equal to 220mm and less than or equal to 450mm.

[0069] The snowplow also includes a snow-throwing assembly, which includes a snow-throwing cylinder 160 and snow-throwing elements. The snow-throwing cylinder 160 is located behind the snow inlet housing 150 and can be rotated to change the direction of snow discharge. At least a portion of the snow-throwing elements is located within the snow inlet housing 150. The snow-throwing elements rotate about a second axis to throw snow from the snowplow blades 142 toward the snow-throwing cylinder 160. Specifically, at least a portion of the snow-throwing elements is located within the second receiving space of the snow inlet housing 150. The snow-throwing elements can employ existing structures, which will not be described in detail here.

[0070] The energy system includes a battery pack, which can be a single battery pack or multiple battery packs. The power system includes a motor, and the battery pack supplies power to the motor. In some embodiments, the snowplow is a second-order snowplow, with the snowplow blade 142 and the snow-throwing component driven separately. In some embodiments, the snowplow is a first-order snowplow, with the snowplow blade 142 and the snow-throwing component sharing a single motor.

[0071] The snowplow also includes at least one battery pack for powering a first motor that drives the snowplow assembly 140. Specifically, the first motor, powered by the battery pack, drives the shaft 141 to rotate, thereby rotating the snowplow paddle 142. The snowplow also includes a second motor for driving the snow-throwing component to rotate. The first and second motors can share a single battery pack, or there can be one battery pack for the first motor and another battery pack for the second motor.

[0072] The snow-throwing assembly also includes a snow-throwing housing, the bottom end of the snow-throwing tube 160 is connected to the snow-throwing housing, the snow-throwing housing is connected to the snow-inlet housing 150, and at least part of the snow-throwing components are disposed inside the snow-throwing housing.

[0073] See Figure 2 The height difference L3 between the lower edge of the snow-throwing tube 160 and the upper edge of the snow-inlet housing 150 is less than or equal to 50 mm, to prevent the snow-inlet housing 150 from blocking the snow-throwing tube 160 from throwing snow outwards. In some embodiments, the height difference L3 between the lower edge of the snow-throwing tube 160 and the upper edge of the snow-inlet housing 150 is less than or equal to 30 mm. In some embodiments, the height difference L3 between the lower edge of the snow-throwing tube 160 and the upper edge of the snow-inlet housing 150 is equal to 50 mm, 40 mm, 30 mm, 20 mm, 10 mm, or 0 mm.

[0074] The ratio of the height difference L3 between the lower edge of the snow-throwing tube 160 and the upper edge of the snow-inlet housing 150 to the total height L4 of the snow-throwing tube 160 is less than or equal to 0.2, so as to prevent the snow-inlet housing 150 from blocking the snow-throwing tube 160 from throwing snow outward.

[0075] The snow inlet housing 150 also has a rear side surface 156, which is the rear surface of the back plate 154. The minimum distance L5 from the snow throw tube 160 to the rear side surface 156 is greater than or equal to 30 mm and less than or equal to 80 mm. In some embodiments, the minimum distance L5 from the snow throw tube 160 to the rear side surface 156 is greater than or equal to 50 mm and less than or equal to 60 mm. In some embodiments, the minimum distance L5 from the snow throw tube 160 to the rear side surface 156 is equal to 55 mm.

[0076] The snowplow 142 includes a plurality of snowplow blades 1421, the distance from the farthest point on the snowplow blade 1421 to the first axis 1411 being the radius of the snowplow 142. In some embodiments, the snowplow blades 1421 extend substantially along a helical surface. In some embodiments, the snowplow blades 1421 extend substantially along a plane in a helical shape.

[0077] The snowplow blade 1421 includes a blade body 14211 and a plurality of snowplow teeth 14212, the snowplow teeth 14212 being disposed on the side of the blade body 14211 away from the first axis 1411. The snowplow teeth 14212 and the blade body 14211 can be disposed on the same plane, or alternatively, see [reference needed]. Figure 11 The snow-sweeping teeth 14212 and the blade body 14211 form an angle β, which is greater than or equal to 30 degrees and less than or equal to 45 degrees. In some embodiments, the angle β is equal to 30 degrees, 35 degrees, 40 degrees, or 45 degrees. By forming the angle β, the snow-sweeping teeth 14212 guide the snow, and during the rotation of the snow-sweeping blade 1421, the snow-sweeping teeth 14212 guide the snow to move into the interior of the snow inlet housing 150.

[0078] In some embodiments, the ratio of the minimum distance L6 between the projection of the rear edge of the snowplow 142 onto the first plane 101 and the projection of the highest point 1511 of the front opening 151 onto the first plane 101 to the diameter D of the snowplow 142 is less than or equal to 0.65; the first plane 101 is substantially parallel to the ground plane. The snowplow 142 is not uniformly distributed around the first axis 1411, therefore there is a minimum distance L6 between the projection of the rear edge of the snowplow 142 onto the first plane 101 and the projection of the highest point 1511 of the front opening 151 onto the first plane 101. It can be understood that, in the front-rear direction, the rear edge of the snowplow 142 is located behind the highest point 1511 of the front opening 151.

[0079] like Figure 4 As shown. The ratio of the minimum distance L6 to the diameter D of the snowplow 142 is less than or equal to 0.65. That is, along the front-back direction, the highest point 1511 of the front opening 151 is moved as far back as possible, and the top of the front opening 151 is further back, so as to further avoid the highest point 1511 of the front opening 151 from contacting the snow and reduce the resistance during the forward movement.

[0080] In some embodiments, the ratio of the minimum distance L6 between the projection of the rear edge of the snowplow 142 onto the first plane 101 and the projection of the highest point 1511 of the front opening 151 onto the first plane 101 to the diameter D of the snowplow 142 is less than or equal to 0.6.

[0081] The difference between the diameter D of the snowplow 142 and the minimum distance L6 is greater than or equal to 20 mm. In some embodiments, the difference between the diameter D of the snowplow 142 and the minimum distance L6 is greater than or equal to 30 mm. In some embodiments, the difference between the diameter D of the snowplow 142 and the minimum distance L6 is equal to 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, or 50 mm.

[0082] In some embodiments, the distance L6 between the projection of the rear edge of the snowplow 142 onto the first plane 101 and the projection of the highest point 1511 of the front opening 151 onto the first plane 101 is greater than or equal to 100 mm and less than or equal to 300 mm; the diameter D of the snowplow 142 is greater than or equal to 220 mm and less than or equal to 450 mm; and the first plane 101 is substantially parallel to the ground plane. In some embodiments, the distance L6 between the projection of the rear edge of the snowplow 142 onto the first plane 101 and the projection of the highest point 1511 of the front opening 151 onto the first plane 101 is greater than or equal to 150 mm and less than or equal to 250 mm. In some embodiments, the distance L6 between the projection of the rear edge of the snowplow 142 onto the first plane 101 and the projection of the highest point 1511 of the front opening 151 onto the first plane 101 is equal to 100 mm, 120 mm, 150 mm, 180 mm, 200 mm, 220 mm, 250 mm, 280 mm, or 300 mm.

[0083] See Figures 1 to 10 The snowplow also includes snowshoes 170, which are disposed on the snow inlet housing 150. During forward movement, the snowshoes 170 rub against the snow, reducing forward resistance. Normally, two snowshoes 170 are positioned on the left and right sides of the snow inlet housing 150, and their positions can be adjusted vertically. However, during adjustment, the snowshoes 170 may twist, resulting in one being higher than the other. In this embodiment, at least two snowshoes 170 are spaced apart at the rear of the snow inlet housing 150 to reduce forward resistance and prevent the snow inlet housing 150 from tilting up on the snow.

[0084] like Figure 5 As shown, along the front-to-back direction, the ratio of the width W1 of the snowshoe 170 to the width W2 of the snow inlet shell 150 is greater than or equal to 0.6 and less than or equal to 1. In some embodiments, along the front-to-back direction, the ratio of the width W1 of the snowshoe 170 to the width W2 of the snow inlet shell 150 is greater than or equal to 0.7 and less than or equal to 0.9. In some embodiments, along the front-to-back direction, the ratio of the width W1 of the snowshoe 170 to the width W2 of the snow inlet shell 150 is equal to 0.6, 0.7, 0.8, 0.9, or 1.

[0085] In this embodiment, two snowshoes 170 are provided, with a distance of n between them along the left-right direction. The width of the snow inlet shell 150 is m, where n is greater than or equal to 0.6*m and less than or equal to m. This ensures a large distance between the two snowshoes 170, providing stable support to the snow inlet shell 150 and maintaining its balance.

[0086] Because the rear space of the snow inlet shell 150 is small, the position adjustment of the snowshoe 170 is limited. In this embodiment, the snowshoe 170 can be adjusted along the direction of the first straight line 103, and the angle between the first straight line 103 and the ground plane is greater than or equal to 30 degrees and less than or equal to 60 degrees, so as to make full use of the space. In some embodiments, the angle between the first straight line 103 and the ground plane is equal to 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees or 60 degrees.

[0087] See Figures 5 to 7 A bracket 180 is provided on the snow inlet housing 150. One of the bracket 180 and the snow boot 170 is provided with an elongated hole 171, and the other is provided with a locking hole 181. The elongated hole 171 extends along the first straight line 103. The snow boot 170 and the bracket 180 are detachably connected by a locking member 190, which passes through the locking hole 181 and the elongated hole 171.

[0088] In this embodiment, the snowshoe 170 has an elongated hole 171, and the bracket 180 has a locking hole 181. The locking member 190 can be a bolt and nut joint structure, or the locking hole 181 can be a threaded hole, and the locking member 190 can be a bolt. The snowshoe 170 can be tilted upwards or downwards along the direction of the elongated hole 171, see [reference]. Figure 5 The snowshoe 170 is in its lowest position, with a locking element 190 abutting against the lowest end of the elongated hole 171; see also Figure 6 The snowshoe 170 is in the highest position, and another locking member 190 abuts against the highest end of the elongated hole 171.

[0089] Furthermore, the snowshoe 170 is provided with a first inclined surface 172, and the support 180 is provided with a second inclined surface 182. The first inclined surface 172 and the second inclined surface 182 abut against each other, and both the first inclined surface 172 and the second inclined surface 182 extend parallel to the first straight line 103. The first inclined surface 172 and the second inclined surface 182 cooperate to limit and guide the movement. When adjusting the position of the snowshoe 170, the snowshoe 170 slides along the second inclined surface 182, thereby ensuring that the snowshoe 170 always moves along the first straight line 103.

[0090] In this embodiment, the angle between the first straight line 103 and the ground plane is 45 degrees. The snowshoe 170 has an isosceles right triangle structure. The snowshoe 170 also includes a first support surface 173 and a second support surface 174. The first support surface 173 and the second support surface 174 are arranged perpendicularly. The angle between the first support surface 173 and the first inclined plane 172 is 45 degrees, and the angle between the second support surface 174 and the first inclined plane 172 is 45 degrees. During use, after the first support surface 173 wears down, the second support surface 174 can be brought into contact with the snow, achieving double-sided use and improving service life.

[0091] Specifically, after the first support surface 173 is worn, the second support surface 174 can be made to contact the snow by rotating and / or flipping the snow boot 170; or the two snow boots 170 can be interchanged and the second support surface 174 can be made to contact the snow by rotating and / or flipping the snow boots 170.

[0092] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
