Description

Technical Field

[0001] This application relates to the field of power tool technology, and more particularly to a tracked walking device. Background Technology

[0002] The snowplow's drive wheels, guide wheels, and tracks have significant gaps at their meshing points. This creates a risk of fingers getting caught if accidentally inserted into these gaps while moving forward or backward. Furthermore, snow easily accumulates between the tracks and protective side plates during icy and snowy weather, and this snow, once frozen, is difficult to remove, hindering the machine's normal operation. Existing tracked drive modules do not adequately address both preventing finger pinching and effectively clearing snow or debris. Summary of the Invention

[0003] In view of this, the purpose of this application is to propose a tracked walking device that can solve the problem of hand pinching safety during movement while expelling snow or foreign objects from inside the protective side plate.

[0004] To achieve the above objectives, this application provides a tracked walking device, comprising: a base; a track mechanism disposed on the side of the base, including a guide wheel, a drive wheel, and a track, wherein the guide wheel and the drive wheel are spaced apart, and the track is wound around the guide wheel and the drive wheel, and the points where the guide wheel and the drive wheel enter and exit the track are defined as danger zones; a tensioning mechanism configured to tension the track by adjusting the spacing between the guide wheel and the drive wheel; and a protective cover plate disposed on the side of the track mechanism away from the base to shield the danger zones, wherein the protective cover plate has an integrated structure, and the middle area of ​​the protective cover plate at least partially forms a clearance space for the discharge of foreign objects with the track.

[0005] Furthermore, the two ends of the protective cover are arc-shaped, and the arc-shaped ends respectively cooperate with the edges of the guide wheel or the drive wheel.

[0006] Furthermore, the protective cover is located between the guide wheel and the drive wheel, and extends from the guide wheel to the drive wheel.

[0007] Furthermore, the protective cover is provided with an operating opening, which corresponds to the operating part of the tensioning mechanism.

[0008] Furthermore, it also includes a cover, which is configured to close the operation opening, and the cover is detachably connected to the protective cover plate.

[0009] Furthermore, the protective cover plate has at least a partial first recess in its middle region, the first recess being located at the bottom of the protective cover plate and recessed upwards.

[0010] Furthermore, the middle region of the protective cover plate is provided with at least a first recess and a second recess, the first recess being located at the bottom of the protective cover plate and recessed upwards, and the second recess being located at the top of the protective cover plate and recessed downwards.

[0011] Furthermore, it also includes an adjustment cover plate for at least partially obscuring the clearance space formed by the first recess and the track, the adjustment cover plate being detachably connected to the protective cover plate.

[0012] Furthermore, the protective cover plate has at least a partial second recess in its middle region, the second recess being located at the top of the protective cover plate and recessed downwards.

[0013] Furthermore, the tracked walking device is an intelligent snow sweeper.

[0014] The tracked walking device provided in this application includes a base, a track mechanism, a tensioning mechanism, and a protective cover plate. The track mechanism, located on the side of the base, includes guide wheels, drive wheels, and a track. The guide wheels and drive wheels are spaced apart, and the track is wound around the guide wheels and drive wheels. The points where the guide wheels and drive wheels enter and exit the track are defined as danger zones. The tensioning mechanism is configured to tension the track by adjusting the interval between the guide wheels and drive wheels. The protective cover plate is located on the side of the track mechanism away from the base to shield the danger zones. By reducing the gap at the meshing points of the drive wheels, guide wheels, and track, fingers cannot be inserted into the danger zones, thus preventing hand pinching safety issues during operation. Furthermore, the protective cover plate adopts an integrated structure, which is easier to install compared to a non-integrated structure. In addition, the middle area of ​​the protective cover plate at least partially forms a clearance space with the track, allowing snow or foreign objects inside the protective cover plate to be discharged through this clearance space. The tracked walking device provided in this application not only provides anti-pinch protection but also facilitates the discharge of snow / foreign objects, improving the safety and stability of the tracked walking device to a certain extent.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

[0024] One embodiment of this application provides a tracked walking device 100 that can solve the problem of hand pinching safety during movement while also solving the problem of snow or foreign object removal. For example... Figure 1As shown, the tracked walking device 100 of this embodiment includes a base 200, a track mechanism 300, a tensioning mechanism, and a protective cover plate 400. The track mechanism 300 is disposed on the side of the base 200. The track mechanism 300 includes a guide wheel 310, a drive wheel 320, and a track 330. There is a certain gap between the guide wheel 310 and the drive wheel 320. The track 330 is wound around the guide wheel 310 and the drive wheel 320. The tensioning mechanism is configured to tension the track 330 by adjusting the gap between the guide wheel 310 and the drive wheel 320, so that the track 330 has a certain tension force and is tightly engaged with the two wheels. During the movement of the tracked walking device 100, the motor drives the drive wheel 320 to rotate, and the drive wheel 320 drives the track 330 to rotate in the direction of travel, thereby driving the entire machine to move. The engagement points of the drive wheel 320, guide wheel 310, and track 330 have a large gap. If a finger is accidentally inserted into this gap during forward or backward movement, there is a risk of pinching the finger. Therefore, the points where the guide wheel 310 and drive wheel 320 enter and exit the track 330 are defined as the danger zone 340. These points are located near the tangent points of the track 330 and guide wheel 310, and the tangent points of the track 330 and drive wheel 320. The tracked walking device 100 provided in this embodiment adds a protective cover plate 400 to solve the finger pinching safety problem during movement. Specifically, the protective cover plate 400 is located on the side of the track mechanism 300 away from the base 200 to shield the danger zone 340. By reducing the gap at the engagement points of the drive wheel 320, guide wheel 310, and track 330, fingers cannot be inserted into the danger zone 340, thereby avoiding the finger pinching safety problem during movement. Furthermore, the protective cover 400 adopts an integrated structure, which is more convenient to install compared to a protective cover 400 with a non-integrated structure. In this embodiment, the middle area of ​​the protective cover 400 at least partially forms a clearance space 500 between itself and the track 330, allowing snow or foreign objects inside the protective cover 400 to be discharged through this clearance space 500. Thus, by adding the aforementioned protective cover 400, this embodiment not only achieves anti-pinch protection but also facilitates the discharge of snow / foreign objects, thereby improving the safety and stability of the tracked walking device 100 to a certain extent.

[0025] In some embodiments, such as Figure 2 As shown, the protective cover 400 has arc-shaped ends at both ends, which respectively mate with the edges of the guide wheel 310 or the drive wheel 320 to facilitate the installation of the protective cover 400. In this embodiment, as... Figure 2 , Figure 3 and Figure 4As shown, the two ends of the protective cover 400 are curved in shape, concave towards the middle of the protective cover 400. In other embodiments, the two ends of the protective cover 400 may be curved in shape, convex towards the ends of the protective cover 400 (not shown), or the two ends of the protective cover 400 may be a combination of inwardly concave and outwardly convex curved shapes.

[0026] In some embodiments, such as Figure 2 As shown, the protective cover 400 is located between the guide wheel 310 and the drive wheel 320, and extends from the guide wheel 310 to the drive wheel 320.

[0027] In some embodiments, such as Figure 3 As shown, the protective cover 400 is provided with an operating opening 410. The operating opening 410 corresponds to the operating part of the tensioning mechanism, and the user can operate the operating part of the tensioning mechanism through the operating opening 410. Compared with the solution where the protective cover 400 does not have an operating opening 410, this embodiment allows adjustment of the tensioning mechanism without disassembling and installing the protective cover 400, making the operation of tensioning the track 330 simpler and more convenient. It should be noted that the shape of the operating opening 410 can be... Figure 3 The rectangle shown can also be other shapes set according to actual needs. The position of the operation opening 410 can be close to the guide wheel 310 or close to the drive wheel 320. This embodiment does not limit this.

[0028] In some embodiments, the tracked walking device 100 further includes a cover, which is correspondingly disposed with respect to the operating opening 410 to close the operating opening 410. The cover is detachably connected to the protective cover plate 400, including but not limited to a flip cover, a snap fastener, or other conventional fixing methods. When adjustment is required, the cover can be opened to remove the obstruction of the operating opening 410; when adjustment is not required, the cover is closed to provide protection.

[0029] In some embodiments, the protective cover plate 400 has at least a partial first recess in its middle region. The first recess is located at the bottom of the protective cover plate 400 and is recessed upwards, forming a clearance space 500 between the first recess and the track 330 for the discharge of snow or foreign objects. In this embodiment, the protective cover plate 400 has one first recess. In other embodiments, the protective cover plate 400 has multiple first recesses, which may be arranged continuously or at intervals.

[0030] In some embodiments, the protective cover plate 400 has at least a partial second recess in its middle region. The second recess is located at the top of the protective cover plate 400 and is recessed downwards, forming a clearance space 500 between the second recess and the track 330 for the discharge of snow or foreign objects. In this embodiment, the protective cover plate 400 has one second recess. In other embodiments, the protective cover plate 400 has multiple second recesses, which may be provided continuously or at intervals.

[0031] In some embodiments, the middle region of the protective cover plate 400 is provided with at least a first recess and a second recess. The first recess is located at the bottom of the protective cover plate 400 and is recessed upward, while the second recess is located at the top of the protective cover plate 400 and is recessed downward. The first recess and the second recess respectively form a clearance space 500 between the first recess and the track 330. Compared with the aforementioned embodiments where the protective cover plate only has a first recess or only has a second recess, this embodiment provides both a first recess and a second recess on the protective cover plate, which is beneficial to increase the clearance space and allow snow or foreign objects inside the protective cover plate to be discharged more quickly and in a timely manner.

[0032] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the protective cover 400 has a first recess and a second recess in its middle region. In other embodiments, the number of first and second recesses in the middle region of the protective cover 400 can be other combinations, such as one first recess and multiple second recesses, or multiple first recesses and multiple second recesses, etc., and this embodiment is not limited thereto. Specifically, when the middle region of the protective cover 400 has multiple first recesses, the multiple first recesses can be arranged continuously or intermittently. When the middle region of the protective cover 400 has multiple second recesses, the multiple second recesses can be arranged continuously or intermittently.

[0033] In some embodiments, such as Figure 4 As shown, the tracked walking device 100 also includes an adjustment cover plate 600, which is used to at least partially cover the clearance space 500 formed by the first recess and the track 330. The adjustment cover plate 600 is detachably connected to the protective cover plate 400. Depending on the actual situation, the user can adjust the size of the clearance space 500 by installing or replacing the adjustment cover plate 600, so that the tracked walking device 100 can adapt to different road conditions, such as gravel roads and snow-covered roads.

[0034] In this embodiment, the tracked walking device 100 is an intelligent snowplow. In other embodiments, the tracked walking device 100 can also be other devices with a tracked chassis, including but not limited to outdoor inspection robots, agricultural robots, etc.

[0035] According to the above embodiments, the tracked walking device 100 provided in this specification has a protective cover plate 400. The protective cover plate 400 is disposed on the side of the track mechanism 300 away from the base 200 to shield the danger zone 340. By reducing the gap at the meshing points of the drive wheel 320, guide wheel 310, and track 330, fingers cannot be inserted into the danger zone 340, thereby avoiding hand-pinching safety issues during operation. The protective cover plate 400 adopts an integrated structure, which is more convenient to install compared to non-integrated protective side plates. At least partially, the middle area of ​​the protective cover plate 400 forms a clearance space 500 with the track 330, allowing snow or foreign objects inside the protective cover plate 400 to be discharged through the clearance space 500. Thus, while achieving anti-pinch protection, it also facilitates the discharge of snow / foreign objects, improving the safety and stability of the tracked walking device 100 to a certain extent.
