Description

Technical Field

[0001] This utility model belongs to the field of transportation vehicle technology, specifically, it relates to a shuttle vehicle. Background Technology

[0002] The shuttle is equipped with wheel bearings, guide wheels, and current collector arms. If the vehicle leaks liquid, the liquid dripping into these structures can damage the components. The shuttles in the related technology do not have a structure to prevent these components from dripping. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the purpose of this utility model is to provide a shuttle vehicle, comprising: a chassis body; at least one wheel assembly mounted on the chassis body, the wheel assembly being used to drive the chassis body to move; at least one guide wheel mounted on the chassis body, the guide wheel protruding from the edge of the chassis body; at least one current collector arm mounted on the chassis body; at least one first protective component mounted on the chassis body, each wheel assembly including a bearing, the bearing being mounted on the chassis body, at least a portion of the first protective component being located on top of the bearing and shielding the corresponding bearing; at least one second protective component mounted on the chassis body, at least a portion of any second protective component being arranged circumferentially along the corresponding guide wheel, the second protective component being capable of shielding a portion of the corresponding guide wheel; and at least one third protective component mounted on the chassis body, at least a portion of any third protective component being located on top of the corresponding current collector arm and shielding the current collector arm.

[0005] This application discloses a shuttle vehicle, which can be a mother-daughter vehicle for transporting goods in a warehouse. The shuttle vehicle includes a chassis body, wheel assemblies, guide wheels, and current collector arms, all of which are mounted on the chassis body. Specifically, there is at least one wheel assembly; if there are multiple wheel assemblies, they are respectively mounted on both sides of the chassis body along its width, and the wheel assemblies are used to drive the chassis body to move. There is at least one guide wheel, which can cooperate with a track to guide the chassis body. The guide wheel protrudes from the edge of the chassis body to facilitate contact with external tracks or other guiding structures. There can be one or multiple current collector arms.

[0006] Furthermore, the shuttle also includes structures for protecting the wheel assemblies, guide wheels, and current collector arms. To protect the wheel assemblies, this application provides first protective components in the shuttle, the number of which is the same as the number of wheel assemblies, with each component corresponding to the others. Each wheel assembly includes a wheel and a bearing, the bearing being mounted on the chassis body. The shuttle includes a drive shaft mounted on the chassis body, the bearing being fitted onto the drive shaft and supporting it. The drive shaft is connected to the wheel and can drive the wheel to rotate, enabling the wheel to travel on the ground and thus moving the chassis body. The first protective components protect the bearings from liquid dripping onto them. Specifically, at least a portion of each first protective component is located on top of the bearing and can shield the corresponding bearing, thereby preventing liquid from dripping onto the bearing and providing protection.

[0007] Furthermore, to prevent the guide wheels from splashing liquid onto other components in the shuttle, this application includes a second protective assembly in the shuttle. The number of second protective assemblies is the same as the number of guide wheels, and they are arranged in a one-to-one correspondence. Understandably, when the guide wheels rotate, the liquid on their surface will splash outwards under centrifugal force. To block the liquid splashed from the guide wheels, a shielding structure needs to be provided around the guide wheels. Specifically, at least a portion of the second protective assembly is arranged along the circumference of the guide wheels. The second protective assembly can shield a portion of the corresponding guide wheel assembly, thus blocking the liquid splashed from the guide wheels and preventing it from dripping onto other components in the shuttle.

[0008] Furthermore, to protect the current collector arms, this application also includes a third protective assembly in the shuttle vehicle. The number of third protective assemblies is the same as the number of current collector arms, with each assembly corresponding to the previous one. The third protective assembly is installed on the chassis body, with at least a portion of each third protective assembly located on top of the corresponding current collector arm, allowing the third protective assembly to shield the current collector arm. In this way, the current collector arms are protected by the third protective assembly, which can block liquids and prevent them from dripping onto the current collector arms, thus providing protection.

[0009] By incorporating a first and third protective assembly within the shuttle, the bearings and current collector arms in the wheel assembly can be protected respectively, preventing liquid from dripping onto them. A second protective assembly within the shuttle can shield against liquid splashed from the guide wheels, preventing the guide wheels from splashing liquid onto other components within the shuttle. The first, second, and third protective covers can all be mounted to the chassis body with screws, offering flexible and simple installation and easy disassembly. Compared to related products, the first, second, and third protective covers in this application exhibit a high degree of modularity, facilitating their use in various different products.

[0010] The shuttle vehicle according to the present invention may also have the following distinguishing technical features:

[0011] In some technical solutions, optionally, any wheel assembly further includes: a wheel; the shuttle further includes: a drive shaft, a bearing for supporting the drive shaft, a chassis body having a first mounting plate, the drive shaft passing through the first mounting plate and the bearing in sequence and connected to the wheel, the drive shaft for driving the wheel to rotate; any first protective assembly includes: a bearing shield, mounted on the first mounting plate, the bearing shield being located on top of the bearing and shielding the bearing; a drive shaft shield, mounted on the first mounting plate, the drive shaft shield being located on top of the drive shaft and shielding a portion of the drive shaft, the bearing shield and the drive shaft shield being located on opposite sides of the first mounting plate.

[0012] In this technical solution, the structures of the wheel assembly and the first protective assembly are specifically defined. The wheel assembly also includes wheels, and the shuttle includes a drive shaft for driving the wheels. Specifically, the chassis body has a first mounting plate, a bearing is located on the side of the first mounting plate facing outwards, and the drive shaft passes through the first mounting plate and the bearing in sequence to connect with the wheels. The drive shaft can rotate under the drive of a power unit, thereby enabling the drive shaft to drive the wheels to rotate. Understandably, since the bearing is located on the side of the first mounting plate facing outwards, there is a risk of liquid dripping onto the bearing or the mating surface between the bearing and the drive shaft. To protect the bearing, this application includes a component in the first protective assembly for shielding the bearing.

[0013] Specifically, each of the first protective assembly components includes a bearing shield and a drive shaft shield. The bearing shield is used to shield the bearing, and the drive shaft shield is used to shield the portion of the drive shaft near the bearing. Specifically, the bearing shield is mounted on the first mounting plate, located on top of the bearing. This allows the bearing shield to block liquid, preventing liquid from dripping onto the bearing and thus protecting it. The drive shaft shield is mounted on the first mounting plate, with the bearing shield and drive shaft shield located on opposite sides of the first mounting plate. The drive shaft shield is located on the top of the drive shaft near the bearing, shielding that side of the drive shaft near the bearing and preventing liquid from dripping onto the mating area between the drive shaft and the bearing, thus preventing liquid from entering the bearing.

[0014] In one possible technical solution, there are four wheels, with two wheels located on the first side of the chassis body along the width direction and the other two wheels located on the second side of the chassis body along the width direction. The number of first mounting plates is the same as the number of wheels, and they are arranged one-to-one with each of the multiple wheels. The drive shaft extends along the width direction of the chassis body and passes through the first mounting plate and the bearing in sequence to connect with the wheel. The bearing supports the drive shaft so that the bearing can rotate smoothly.

[0015] By providing a bearing shield and a drive shaft shield in the first protective assembly, and by placing the bearing shield and the drive shaft shield on both sides of the first mounting plate respectively, the bearing and the mating part of the drive shaft with the bearing can be shielded, preventing liquid from dripping onto the bearing and thus protecting the bearing.

[0016] In some technical solutions, optionally, any first protective component further includes: a first seal, mounted on a first mounting plate, the first seal being located between the bearing shield and the drive shaft shield.

[0017] In this technical solution, the structure of the first protective component is further defined. To improve the protective effect of the first protective component on the bearing, this application also provides a first seal in the first protective component. The first seal is used to seal the gap between the drive shaft shield and the first mounting plate. Specifically, the first seal is located between the bearing shield and the drive shaft shield. Since the bearing shield and the drive shaft shield are located on opposite sides of the first mounting plate, a gap can easily exist between the drive shaft shield and the first mounting plate. The first seal is installed on the first mounting plate and fits against the first mounting plate, thereby enabling the first seal to seal the gap between the drive shaft shield and the first mounting plate, preventing liquid from entering the bearing through the gap between the drive shaft shield and the first mounting plate.

[0018] The first sealing element can be made of a material with a certain degree of elasticity to ensure a good sealing effect; for example, the first sealing element can be a rubber gasket.

[0019] By incorporating a first seal in the first protective assembly, liquid can be prevented from seeping into the bearing through gaps in the first protective assembly, thereby enhancing the protective effect of the first protective assembly.

[0020] In some technical solutions, the bearing shielding member may optionally include: a curved section located at the top of the bearing, the shape of which is adapted to the shape of the bearing; and at least two extension sections disposed at both ends of the curved section along the radial direction of the bearing, the extension sections extending in a direction away from the curved section.

[0021] In this technical solution, the structure of the bearing shield is defined. The bearing shield has a multi-segment structure to improve its protective effect. The bearing shield includes a curved segment and an extension segment connected to the curved segment. The curved segment shields the bearing, and the extension segment increases the shielding area of ​​the bearing shield. Specifically, the curved segment is located at the top of the bearing, and its shape matches the shape of the bearing. This improves the shielding effect of the curved segment while reducing the installation space occupied by the curved segment.

[0022] Furthermore, there are at least two extension sections, each connected to one end of the curved section along the radial direction of the bearing, and extending in a direction away from the curved section. In this way, the extension sections can shield the area surrounding the bearing, preventing liquid from splashing onto the bearing and further enhancing the protective effect of the bearing shield.

[0023] By incorporating curved and extended sections into the bearing shield, the protective effect of the bearing shield on the bearing can be improved, while also reducing the installation space occupied by the bearing shield, lowering the possibility of interference between the bearing shield and other components in the shuttle, and facilitating the miniaturization of the product design.

[0024] In some technical solutions, optionally, any first protective component further includes: a wheel shield connected to a bearing shield, at least a portion of the wheel shield being located on top of the wheel and capable of shielding at least a portion of the corresponding wheel.

[0025] In this technical solution, the structure of the first protective assembly is further defined. The first protective assembly also includes a wheel shield for protecting the wheel. The wheel shield is connected to the end of the bearing shield away from the first mounting plate, extends towards the top of the wheel, and at least a portion of the wheel shield is located on the top of the wheel, so that the wheel shield can cover at least a portion of the corresponding wheel. This reduces liquid dripping onto the wheel, thus protecting it. Furthermore, since the wheel and bearing are adjacent, providing a wheel shield connected to the bearing shield in the first protective assembly further enhances the protection of the bearing.

[0026] In some technical solutions, optionally, any second protective component includes: a plurality of shields connected sequentially along the circumference of the respective guide wheel and capable of shielding a portion of the guide wheel, wherein one of the plurality of shields is mounted on the chassis body.

[0027] In this technical solution, the structure of the second protective assembly is defined. Each second protective assembly includes a baffle plate used to shield the circumference of the guide wheel. Specifically, each second protective assembly has multiple baffle plates, which are sequentially connected along the circumference of the corresponding guide wheel so that the baffle plates can surround the circumference of the guide wheel, shielding a portion of the guide wheel. Understandably, when liquid is present on the surface of the guide wheel, as the guide wheel rotates, the liquid will splash around the guide wheel under centrifugal force. If the guide wheel is not shielded, the liquid can easily splash onto other components in the shuttle. To prevent the guide wheel from splashing liquid onto other components, this application provides baffle plates for shielding the guide wheel around its circumference. One of the multiple baffle plates is mounted on the chassis body, and the other baffle plates are sequentially connected along the circumference of the guide wheel. Thus, the guide wheel can be shielded by the baffle plates.

[0028] By setting multiple baffles in the second protective assembly and placing these baffles around the guide wheel, the guide wheel can be shielded, preventing it from splashing liquid onto other parts of the shuttle.

[0029] In some technical solutions, optionally, any second protective component further includes: a base plate connected to the bottom of the plurality of shields, at least a portion of the base plate being located at the bottom of the respective guide wheel.

[0030] In this technical solution, the structure of the second protective component is further defined. Each second protective component also includes a base plate for receiving liquid dripping from the baffles and guide wheels. Specifically, the base plate is connected to the bottom of multiple baffles. Liquid on the guide wheels splashes onto the baffles and flows downwards under its own gravity until it reaches the base plate, which can receive the liquid flowing down from the baffles. Furthermore, at least a portion of the base plate is located at the bottom of the corresponding guide wheel, allowing liquid on the guide wheel to drip onto the base plate.

[0031] Multiple baffles and the base plate can be connected as a whole by welding or by sheet metal processing.

[0032] By incorporating a base plate in the second protective assembly, the liquid flowing down from the guide wheel and the baffle plate can be collected, thus preventing the liquid from flowing freely.

[0033] In some technical solutions, optionally, the chassis body has a sliding contact line, the bottom plate is located between the sliding contact line and the guide wheel, the bottom plate has an angle with the horizontal plane, and the bottom plate extends in a direction away from the guide wheel and away from the sliding contact line.

[0034] In this technical solution, the base plate is further defined. The chassis body has a sliding contact line, which, as a power transmission device, requires waterproof protection. To prevent the guide wheel from splashing liquid onto the sliding contact line, this application places the base plate between the sliding contact line and the guide wheel. The base plate blocks and collects the liquid, preventing it from dripping onto the sliding contact line. Specifically, the base plate is located between the guide wheel and the sliding contact line, and it forms an angle with the horizontal plane, meaning its surface is inclined. The base plate extends away from both the guide wheel and the sliding contact line; that is, while extending away from the sliding contact line, it also extends downwards at an angle, allowing the base plate to guide the liquid away from the sliding contact line. When the guide wheel rotates, it splashes liquid onto the baffle plate. The liquid flows downwards on the baffle plate until it reaches the base plate, where it is collected. Because the base plate extends downwards at an angle, the liquid flows along the base plate away from the sliding contact line, preventing it from dripping onto the sliding contact line.

[0035] By setting the base plate to extend away from the sliding contact line and away from the guide wheel, the liquid can be guided through the base plate to a position away from the sliding contact line, thus protecting the sliding contact line.

[0036] In some technical solutions, optionally, the chassis body has a second mounting plate located between the guide wheel and the adjacent wheel assembly, and one of the multiple shields is mounted on the second mounting plate.

[0037] In this technical solution, the installation method of the baffle plate is specified. The chassis body has a second mounting plate, which is located between the guide wheel and the adjacent wheel. This allows the guide wheel to be separated from the wheel. When the guide wheel rotates and causes liquid to splash, the second mounting plate can provide a certain degree of shielding against the liquid splashed out by the guide wheel, thereby reducing the possibility of liquid splashing onto the wheel and bearing.

[0038] Furthermore, one of the multiple baffles is mounted on the second mounting plate by screws, and the other baffles are sequentially connected along the circumference of the guide wheel to surround the circumference of the guide wheel. The baffles can be connected to the second mounting plate by screws.

[0039] In some technical solutions, optionally, when there are at least two guide wheels, the side of two adjacent guide wheels that are close to each other is exposed to the second protective component along the width direction of the chassis body.

[0040] In this technical solution, the structure of the guide wheels is defined. When there are at least two guide wheels, the at least two guide wheels are respectively arranged on both sides of the chassis body along the width direction. Specifically, along the width direction of the chassis body, the side of two adjacent guide wheels that are close to each other is exposed to the second protective component. This allows the guide wheels to contact the track or other guiding structures, enabling two adjacent guide wheels along the width direction to move along the track and achieve the guiding function of the guide wheels.

[0041] In some technical solutions, optionally, any third protective component includes: a first shielding component, installed on the chassis body, a portion of the first shielding component being located on top of the current collector arm and shielding the current collector arm, and another portion of the first shielding component being located on a first side of the current collector arm; and a second shielding component, connected to the first shielding component, a portion of the second shielding component being located on a second side of the current collector arm.

[0042] In this technical solution, the structure of the third protective component is defined. The third protective component includes a first shielding component and a second shielding component, which are used to protect the top and side of the current collector arm, respectively. Specifically, the first shielding component is mounted on the chassis body, with a portion of it located at the top of the current collector arm. This first shielding component at the top of the current collector arm can shield the current collector arm to prevent liquid from dripping onto it. Additionally, another portion of the first shielding component is located on the first side of the current collector arm, providing shielding for that first side.

[0043] Furthermore, the second shielding assembly is connected to the first shielding assembly for mounting and positioning the second shielding assembly; the two can be connected by screws. A portion of the second shielding assembly is located on the second side of the current collector arm, thus allowing the second side of the current collector arm to be shielded by the second shielding assembly.

[0044] By incorporating a first shielding component and a second shielding component into the third protective assembly, the top and sides of the current collector arm can be shielded through their cooperation, thus enclosing the current collector arm within the third protective assembly. The shielding of the current collector arm by the third protective assembly prevents liquid from dripping onto the current collector arm, thereby protecting it.

[0045] In some technical solutions, optionally, the first shielding component includes: a support member installed on the chassis body, the height of the support member being higher than the height of the current collector arm; a protective cover connected to the top of the support member and shielding the current collector arm; and a second shielding component connected to the protective cover.

[0046] In this technical solution, the structure of the first shielding assembly is defined. The first shielding assembly includes a support member and a protective cover. The support member is mounted on the chassis body and supports the protective cover so that the protective cover can shield the current collector arm. Specifically, the support member is connected to the chassis body by screws, and the protective cover is connected to the top of the support member. Since the height of the support member is higher than the height of the current collector arm, at least a portion of the protective cover is higher than the height of the current collector arm, and at least a portion of the protective cover is located on top of the current collector arm and shields it. There can be one or more support members. A second shielding assembly is connected to the protective cover for installation and fixation.

[0047] In some technical solutions, optionally, both the protective cover and the second shielding assembly have a flow guiding surface that extends away from the current collector arm and away from the top of the protective cover.

[0048] In this technical solution, the structure of the protective cover and the second shielding assembly is defined. To guide liquid dripping onto the protective cover and the second shielding assembly, this application provides a guiding surface in both the protective cover and the second shielding assembly. Specifically, the guiding surface extends away from the current collector arm and away from the top of the protective cover, that is, the guiding surface extends downwards at an angle. This allows the liquid to flow downwards along the guiding surface and in a direction away from the current collector arm. Thus, liquid accumulation on the protective cover and the second shielding assembly is prevented, and the liquid is also directed away from the current collector arm, improving the protection effect on the current collector arm.

[0049] In some technical solutions, optionally, any third protective component further includes: a second seal, the two sides of which are respectively abutted against the protective cover and the second shielding component.

[0050] In this technical solution, the structure of the third protective assembly is further defined. The third protective assembly also includes a second seal, which seals the gap between the protective cover and the second shielding assembly. Specifically, the second seal is located between the protective cover and the second shielding assembly, and its two sides are respectively abutted against the protective cover and the second shielding assembly. Thus, the gap between the protective cover and the second shielding assembly can be sealed by the second seal, preventing liquid from flowing into the current collector arm through the gap between the protective cover and the second shielding assembly.

[0051] The second seal can be made of a material with a certain degree of elasticity to ensure a good sealing effect; for example, the second seal can be a rubber gasket.

[0052] By providing a second seal between the protective cover and the second shielding assembly, liquid can be prevented from seeping into the current collector arm through the gap between the protective cover and the second shielding assembly, thus improving the protective effect of the third protective assembly.

[0066] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0067] The following reference Figures 1 to 8 The shuttle 100 is described according to some embodiments of the present invention.

[0068] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, this application proposes a shuttle 100, comprising: a chassis body 110; at least one wheel assembly 120 mounted on the chassis body 110, the wheel assembly 120 being used to drive the chassis body 110 to move; at least one guide wheel 130 mounted on the chassis body 110, the guide wheel 130 protruding from the edge of the chassis body 110; at least one current collector arm 140 mounted on the chassis body 110; at least one first protective assembly 150 mounted on the chassis body 110, each wheel assembly 120 including a bearing 121 mounted on the chassis body 110. 10. At least a portion of the first protective component 150 is located on top of the bearing 121 and shields the corresponding bearing 121; at least one second protective component 160 is mounted on the chassis body 110, at least a portion of any second protective component 160 is arranged circumferentially along the corresponding guide wheel 130, and the second protective component 160 is capable of shielding a portion of the corresponding guide wheel 130; at least one third protective component 170 is mounted on the chassis body 110, at least a portion of any third protective component 170 is located on top of the corresponding current collector arm 140 and shields the current collector arm 140.

[0069] This application discloses a shuttle 100, which can be a mother-daughter vehicle for transporting goods in a warehouse. The shuttle 100 includes a chassis body 110, wheel assemblies 120, guide wheels 130, and current collector arms 140, all of which are mounted on the chassis body 110. Specifically, there is at least one wheel assembly 120. If there are multiple wheel assemblies 120, they are respectively mounted on both sides of the chassis body 110 along its width, and the wheel assemblies 120 are used to move the chassis body 110. There is at least one guide wheel 130, which can cooperate with a track to guide the chassis body 110. The guide wheel 130 protrudes from the edge of the chassis body 110 to facilitate contact with external tracks or other guiding structures. There can be one or multiple current collector arms 140.

[0070] Furthermore, the shuttle 100 also includes a structure for protecting the wheel assembly 120, guide wheel 130, and current collector arm 140. To protect the wheel assembly 120, this application provides a first protective component 150 in the shuttle 100. The number of first protective components 150 is the same as the number of wheel assemblies 120, and they are arranged in a one-to-one correspondence. Each wheel assembly 120 includes a wheel 122 and a bearing 121. The bearing 121 is mounted on the chassis body 110. The shuttle 100 includes a drive shaft 180 mounted on the chassis body 110. The bearing 121 is sleeved on the drive shaft 180 and supports the drive shaft 180. The drive shaft 180 is connected to the wheel 122 and can drive the wheel 122 to rotate, so that the wheel 122 can travel on the ground to move the chassis body 110. The first protective component 150 is used to protect the bearing 121 from liquid dripping onto it. Specifically, at least a portion of any first protective component 150 is located on top of the bearing 121 and can shield the corresponding bearing 121, thereby preventing liquid from dripping onto the bearing 121 and thus protecting the bearing 121.

[0071] Furthermore, to prevent the guide wheels 130 from splashing liquid onto other components in the shuttle 100, this application provides a second protective assembly 160 in the shuttle 100. The number of second protective assemblies 160 is the same as the number of guide wheels 130, and they are arranged one-to-one. Understandably, when the guide wheels 130 rotate, the liquid on the surface of the guide wheels 130 will splash outwards under the action of centrifugal force. In order to block the liquid splashed out by the guide wheels 130, a shielding structure needs to be provided around the guide wheels 130. Specifically, at least a portion of the second protective assembly 160 is arranged around the guide wheels 130. The second protective assembly 160 can shield a portion of the corresponding guide wheel 130 assembly, and the liquid splashed out by the guide wheels 130 will be blocked by the second protective assembly 160 to prevent the liquid from dripping onto other components in the shuttle 100.

[0072] Furthermore, to protect the current collector arm 140, this application also provides a third protective component 170 in the shuttle 100. The number of third protective components 170 is the same as the number of current collector arms 140, and they are arranged in a one-to-one correspondence. The third protective component 170 is installed on the chassis body 110, and at least a portion of any third protective component 170 is located on top of the corresponding current collector arm 140, so that the third protective component 170 can shield the current collector arm 140. In this way, the current collector arm 140 can be protected by the third protective component 170. The third protective component 170 can block liquid and prevent liquid from dripping onto the current collector arm 140, thereby achieving the protective function of the current collector arm 140.

[0073] By providing a first protective component 150 and a third protective component 170 in the shuttle 100, the bearing 121 and the current collector arm 140 in the wheel assembly 120 can be protected respectively, preventing liquid from dripping onto the bearing 121 and the current collector arm 140. By providing a second protective component 160 in the shuttle 100, liquid splashed from the guide wheel 130 can be blocked, preventing the guide wheel 130 from splashing liquid onto other components in the shuttle 100. The first protective cover 174, the second protective cover 174, and the third protective cover 174 can all be installed on the chassis body 110 with screws, and the installation method is flexible and simple, facilitating disassembly. Compared with related products, the first protective cover 174, the second protective cover 174, and the third protective cover 174 in this application have a higher degree of modularity, making them easy to use in a variety of different products.

[0074] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 4 As shown, any wheel assembly 120 further includes: a wheel 122; the shuttle 100 further includes: a drive shaft 180, a bearing 121 for supporting the drive shaft 180, a chassis body 110 having a first mounting plate 111, the drive shaft 180 passing through the first mounting plate 111 and the bearing 121 in sequence and connected to the wheel 122, the drive shaft 180 for driving the wheel 122 to rotate; any first protective assembly 150 includes: a bearing shield 151, mounted on the first mounting plate 111, the bearing shield 151 being located on top of the bearing 121 and shielding the bearing 121; a drive shaft shield 152, mounted on the first mounting plate 111, the drive shaft shield 152 being located on top of the drive shaft 180 and shielding a portion of the drive shaft 180, the bearing shield 151 and the drive shaft shield 152 being located on both sides of the first mounting plate 111 respectively.

[0075] In this embodiment, the structures of the wheel assembly 120 and the first protective assembly 150 are specifically defined. The wheel assembly 120 also includes a wheel 122, and the shuttle 100 includes a drive shaft 180 for driving the wheel 122. Specifically, the chassis body 110 has a first mounting plate 111, a bearing 121 is located on the side of the first mounting plate 111 facing outwards, and the drive shaft 180 passes through the first mounting plate 111 and the bearing 121 in sequence and is connected to the wheel 122. The drive shaft 180 can rotate under the drive of a power device, thereby enabling the drive shaft 180 to drive the wheel 122 to rotate. Understandably, since the bearing 121 is located on the side of the first mounting plate 111 facing outwards, there is a risk of liquid dripping onto the bearing 121 or the mating surface between the bearing 121 and the drive shaft 180. To protect the bearing 121, this application provides a component for shielding the bearing 121 in the first protective assembly 150.

[0076] Specifically, each of the first protective assembly components includes a bearing shield 151 and a drive shaft shield 152. The bearing shield 151 is used to shield the bearing 121, and the drive shaft shield 152 is used to shield the portion of the drive shaft 180 near the bearing 121. Specifically, the bearing shield 151 is mounted on the first mounting plate 111, and the bearing shield 151 is located on top of the bearing 121. This allows the bearing shield 151 to block liquid, preventing liquid from dripping onto the bearing 121, thus protecting the bearing 121. The drive shaft shield 152 is mounted on the first mounting plate 111. The bearing shield 151 and the drive shaft shield 152 are located on both sides of the first mounting plate 111. The drive shaft shield 152 is located on the top of the drive shaft 180 near the bearing 121 and shields the side of the drive shaft 180 near the bearing 121, thereby preventing liquid from dripping onto the mating part of the drive shaft 180 and the bearing 121 and preventing liquid from entering the bearing 121.

[0077] In one possible embodiment, there are four wheels 122, with two wheels 122 located on the first side of the chassis body 110 along the width direction and the other two wheels 122 located on the second side of the chassis body 110 along the width direction. The number of first mounting plates 111 is the same as the number of wheels 122, and they are arranged one-to-one with the multiple wheels 122. The drive shaft 180 extends along the width direction of the chassis body 110 and passes through the first mounting plate 111 and the bearing 121 in sequence to connect with the wheels 122. The bearing 121 supports the drive shaft 180 so that the bearing 121 can rotate smoothly.

[0078] By providing a bearing shield 151 and a drive shaft shield 152 in the first protective assembly 150, and by placing the bearing shield 151 and the drive shaft shield 152 on both sides of the first mounting plate 111 respectively, the bearing 121 and the mating point between the drive shaft 180 and the bearing 121 can be shielded, preventing liquid from dripping onto the bearing 121 and thus protecting the bearing 121.

[0079] In some embodiments, optionally, such as Figure 3 As shown, any of the first protective components 150 further includes: a first seal 153, which is installed on the first mounting plate 111 and is located between the bearing shield 151 and the drive shaft shield 152.

[0080] In this embodiment, the structure of the first protective component 150 is further defined. To improve the protective effect of the first protective component 150 on the bearing 121, this application also provides a first seal 153 in the first protective component 150. The first seal 153 is used to seal the gap between the drive shaft shield 152 and the first mounting plate 111. Specifically, the first seal 153 is located between the bearing shield 151 and the drive shaft shield 152. Since the bearing shield 151 and the drive shaft shield 152 are located on opposite sides of the first mounting plate 111, a gap can easily exist between the drive shaft shield 152 and the first mounting plate 111. The first seal 153 is installed on and fits against the first mounting plate 111, thereby enabling the first seal 153 to seal the gap between the drive shaft shield 152 and the first mounting plate 111, preventing liquid from entering the bearing 121 from the gap between the drive shaft shield 152 and the first mounting plate 111.

[0081] The first sealing element 153 can be made of a material with a certain degree of elasticity so that the first sealing element 153 has a good sealing effect. For example, the first sealing element 153 can be a rubber gasket.

[0082] By providing a first seal 153 in the first protective assembly 150, liquid can be prevented from seeping into the bearing 121 from the gaps in the first protective assembly 150, thereby improving the protective effect of the first protective assembly 150.

[0083] In some embodiments, optionally, such as Figure 4 As shown, the bearing shield 151 includes: a curved section 154 located at the top of the bearing 121, the shape of the curved section 154 being adapted to the shape of the bearing 121; and at least two extension sections 155 respectively disposed at both ends of the curved section 154 along the radial direction of the bearing 121, the extension sections 155 extending in a direction away from the curved section 154.

[0084] In this embodiment, the structure of the bearing shield 151 is defined. The bearing shield 151 has a multi-segment structure to improve its protective effect. The bearing shield 151 includes a bent segment 154 and an extension segment 155 connected to the bent segment 154. The bent segment 154 is used to shield the bearing 121, and the extension segment 155 is used to increase the shielding area of ​​the bearing shield 151. Specifically, the bent segment 154 is located at the top of the bearing 121, and the shape of the bent segment 154 is adapted to the shape of the bearing 121. This improves the shielding effect of the bent segment 154 on the bearing 121 and reduces the installation space occupied by the bent segment 154.

[0085] Furthermore, there are at least two extension segments 155, each connected to one end of the curved segment 154 along the radial direction of the bearing 121, and the extension segments 155 extend in a direction away from the curved segment 154. In this way, the extension segments 155 can shield the area surrounding the bearing 121, preventing liquid from splashing onto the bearing 121 and further improving the protective effect of the bearing shield 151.

[0086] By providing a bent section 154 and an extended section 155 in the bearing shield 151, the protective effect of the bearing shield 151 on the bearing 121 can be improved, while also reducing the installation space occupied by the bearing shield 151, reducing the possibility of interference between the bearing shield 151 and other components in the shuttle 100, and also facilitating the miniaturization design of the product.

[0087] In some embodiments, optionally, any first protective component 150 further includes: a wheel shield connected to the bearing shield 151, at least a portion of the wheel shield being located on top of the wheel 122 and capable of shielding at least a portion of the corresponding wheel 122.

[0088] In this embodiment, the structure of the first protective component 150 is further defined. The first protective component 150 also includes a wheel shield for shielding and protecting the wheel 122. The wheel shield is connected to the end of the bearing shield 151 away from the first mounting plate 111. The wheel shield extends toward the top of the wheel 122, and at least a portion of the wheel shield is located on the top of the wheel 122, so that the wheel shield can shield at least a portion of the corresponding wheel 122. In this way, liquid dripping onto the wheel 122 can be reduced, thereby protecting the wheel 122. Furthermore, since the wheel 122 and the bearing 121 are arranged adjacent to each other, by providing a wheel shield connected to the bearing shield 151 in the first protective component 150, the protective effect on the bearing 121 can be further improved.

[0089] In some embodiments, optionally, such as Figure 2 , Figure 4 and Figure 5 As shown, any second protective component 160 includes: a plurality of shields 161, which are sequentially connected along the circumference of the corresponding guide wheel 130 and are capable of shielding a portion of the guide wheel 130, and one of the shields 161 is mounted on the chassis body 110.

[0090] In this embodiment, the structure of the second protective component 160 is defined. Each second protective component 160 includes a baffle plate 161 for circumferentially shielding the guide wheel 130. Specifically, each second protective component 160 may have multiple baffle plates 161, which are sequentially connected along the circumference of the corresponding guide wheel 130, so that the baffle plates 161 can surround the periphery of the guide wheel 130, and can shield a portion of the guide wheel 130. Understandably, when liquid is present on the surface of the guide wheel 130, as the guide wheel 130 rotates, the liquid will splash around the guide wheel 130 under centrifugal force. If the guide wheel 130 is not shielded, the liquid can easily splash onto other components in the shuttle 100. To prevent the guide wheel 130 from splashing liquid onto other components, this application provides a shielding plate 161 around the guide wheel 130. One of the shielding plates 161 is mounted on the chassis body 110, and the other shielding plates 161 are connected sequentially along the circumference of the guide wheel 130. Thus, the guide wheel 130 can be shielded by the shielding plate 161. By providing multiple shielding plates 161 in the second protective assembly 160 and placing them around the guide wheel 130, the guide wheel 130 can be shielded by the shielding plates 161, preventing the guide wheel 130 from splashing liquid onto other components in the shuttle 100.

[0091] In some embodiments, optionally, such as Figure 4 and Figure 5 As shown, any second protective component 160 further includes a base plate 162 connected to the bottom of the plurality of shields 161, at least a portion of the base plate 162 being located at the bottom of the corresponding guide wheel 130.

[0092] In this embodiment, the structure of the second protective component 160 is further defined. Each second protective component 160 also includes a base plate 162, which is used to receive liquid dripped from the baffles 161 and the guide wheels 130. Specifically, the base plate 162 is connected to the bottom of the plurality of baffles 161. Liquid splashed from the guide wheels 130 onto the baffles 161 flows downwards under its own gravity until it reaches the base plate 162, which can receive the liquid flowing down from the baffles 161. Furthermore, at least a portion of the base plate 162 is located at the bottom of the corresponding guide wheels 130, allowing liquid on the guide wheels 130 to drip onto the base plate 162.

[0093] The multiple baffles 161 and the base plate 162 can be connected as a whole by welding or by sheet metal processing.

[0094] By providing a base plate 162 in the second protective assembly 160, the liquid flowing down from the guide wheel 130 and the baffle plate 161 can be received by the base plate 162. The base plate 162 plays a role in collecting the liquid and preventing the liquid from flowing randomly.

[0095] In some embodiments, optionally, such as Figure 5 As shown, the chassis body 110 has a sliding contact line 113, and the base plate 162 is located between the sliding contact line 113 and the guide wheel 130. The base plate 162 has an angle with the horizontal plane, and the base plate 162 extends in the direction away from the guide wheel 130 and away from the sliding contact line 113.

[0096] In this embodiment, the base plate 162 is further defined. The chassis body 110 has a sliding contact line 113, which, as a power transmission device, requires waterproof protection. To prevent the guide wheel 130 from splashing liquid onto the sliding contact line 113, the base plate 162 is positioned between the sliding contact line 113 and the guide wheel 130. The base plate 162 blocks and collects the liquid, preventing it from dripping onto the sliding contact line 113. Specifically, the base plate 162 is located between the guide wheel 130 and the sliding contact line 113, and it forms an angle with the horizontal plane, meaning its surface is inclined. The base plate 162 extends away from both the guide wheel 130 and the sliding contact line 113; that is, while extending away from the sliding contact line 113, it also extends downwards at an angle, allowing the base plate 162 to guide the liquid away from the sliding contact line 113. When the guide wheel 130 rotates, the guide wheel 130 splashes the liquid on its surface onto the baffle plate 161. The liquid flows downward on the baffle plate 161 until it flows to the bottom plate 162. The bottom plate 162 collects the liquid. Since the bottom plate 162 extends downward at an angle, the liquid flows along the bottom plate 162 in a direction away from the sliding contact line 113 to avoid the liquid dripping onto the sliding contact line 113.

[0097] By setting the base plate 162 to extend away from the sliding contact line 113 and away from the guide wheel 130, the liquid can be guided through the base plate 162 to a position away from the sliding contact line 113, thereby protecting the sliding contact line 113.

[0098] In some embodiments, optionally, such as Figure 4 As shown, the chassis body 110 has a second mounting plate 112, which is located between the guide wheel 130 and the adjacent wheel assembly 120, and one of the plurality of shields 161 is mounted on the second mounting plate 112.

[0099] In this embodiment, the installation method of the shielding plate 161 is defined. The chassis body 110 has a second mounting plate 112, which is located between the guide wheel 130 and the adjacent wheel 122. In this way, the guide wheel 130 and the wheel 122 can be separated by the second mounting plate 112. When the guide wheel 130 rotates and causes liquid to splash, the second mounting plate 112 can provide a certain shielding effect on the liquid splashed out by the guide wheel 130, so as to reduce the possibility of liquid splashing onto the wheel 122 and the bearing 121.

[0100] Furthermore, one of the multiple baffles 161 is mounted on the second mounting plate 112, and the baffle 161 is connected to the second mounting plate 112 by screws. The other baffles 161 are sequentially connected along the circumference of the guide wheel 130 to surround the circumference of the guide wheel 130. The baffles 161 can be connected to the second mounting plate 112 by screws.

[0101] In some embodiments, optionally, such as Figure 2 As shown, when there are at least two guide wheels 130, along the width direction of the chassis body 110, the side of two adjacent guide wheels 130 that are close to each other is exposed to the second protective assembly 160.

[0102] In this embodiment, the structure of the guide wheel 130 is defined. When there are at least two guide wheels 130, at least two guide wheels 130 are respectively disposed on both sides of the chassis body 110 along the width direction. Specifically, along the width direction of the chassis body 110, the side of two adjacent guide wheels 130 that is close to each other is exposed to the second protective component 160. This allows the guide wheel 130 to contact the track or other guiding structure, enabling two adjacent guide wheels 130 along the width direction to move along the track and realize the guiding function of the guide wheel 130.

[0103] In some embodiments, optionally, such as Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, any third protective component 170 includes: a first shielding component 171, mounted on the chassis body 110, a portion of the first shielding component 171 being located on top of the current collector arm 140 and shielding the current collector arm 140, and another portion of the first shielding component 171 being located on a first side of the current collector arm 140; and a second shielding component 172, connected to the first shielding component 171, a portion of the second shielding component 172 being located on a second side of the current collector arm 140.

[0104] In this embodiment, the structure of the third protective component 170 is defined. The third protective component 170 includes a first shielding component 171 and a second shielding component 172, which are used to protect the top and side of the current collector arm 140, respectively. Specifically, the first shielding component 171 is mounted on the chassis body 110, and a portion of the first shielding component 171 is located on the top of the current collector arm 140. The first shielding component 171 located on the top of the current collector arm 140 can shield the current collector arm 140 to prevent liquid from dripping onto the current collector arm 140. In addition, another portion of the first shielding component 171 is located on the first side of the current collector arm 140, and the first shielding component 171 located on the first side of the current collector arm 140 can shield the first side of the current collector arm 140.

[0105] Furthermore, the second shielding assembly 172 is connected to the first shielding assembly 171 for mounting and positioning the second shielding assembly 172, and the two can be connected by screws. A portion of the second shielding assembly 172 is located on the second side of the current collector arm 140, so that the second side of the current collector arm 140 can be shielded by the second shielding assembly 172.

[0106] By providing a first shielding component 171 and a second shielding component 172 in the third protective component 170, the top and sides of the current collector arm 140 can be shielded through their cooperation, so that the current collector arm 140 is enclosed within the third protective component 170. Through the shielding of the current collector arm 140 by the third protective component 170, liquid can be prevented from dripping onto the current collector arm 140, thereby protecting the current collector arm 140.

[0107] In some embodiments, optionally, such as Figure 8 As shown, the first shielding assembly 171 includes: a support member 173, which is installed on the chassis body 110 and the height of the support member 173 is higher than the height of the current collector arm 140; a protective cover 174, which is connected to the top of the support member 173 and shields the current collector arm 140; and a second shielding assembly 172, which is connected to the protective cover 174.

[0108] In this embodiment, the structure of the first shielding assembly 171 is defined. The first shielding assembly 171 includes a support member 173 and a protective cover 174. The support member 173 is mounted on the chassis body 110 and supports the protective cover 174 so that the protective cover 174 can shield the current collector arm 140. Specifically, the support member 173 is connected to the chassis body 110 by screws, and the protective cover 174 is connected to the top of the support member 173. Since the height of the support member 173 is higher than the height of the current collector arm 140, at least a portion of the protective cover 174 is higher than the height of the current collector arm 140, and at least a portion of the protective cover 174 is located on top of the current collector arm 140 and shields the current collector arm 140. The number of support members 173 can be one or more. The second shielding assembly 172 is connected to the protective cover 174 to install and fix the second shielding assembly 172.

[0109] In some embodiments, optionally, such as Figure 6 , Figure 7 and Figure 8 As shown, both the protective cover 174 and the second shielding assembly 172 have a flow guiding surface 175, which extends in a direction away from the current collector arm 140 and away from the top of the protective cover 174.

[0110] In this embodiment, the structure of the protective cover 174 and the second shielding assembly 172 is defined. To guide liquid dripping onto the protective cover 174 and the second shielding assembly, this application provides a guiding surface 175 in both the protective cover 174 and the second shielding assembly. Specifically, the guiding surface 175 extends away from the current collector arm 140 and away from the top of the protective cover 174, that is, the guiding surface 175 extends obliquely downwards. This allows the liquid to flow downwards along the guiding surface 175 and in a direction away from the current collector arm 140. Thus, liquid accumulation on the protective cover 174 and the second shielding assembly 172 is prevented, and the liquid is also directed away from the current collector arm 140, improving the protection effect on the current collector arm 140.

[0111] In some embodiments, optionally, such as Figure 8 As shown, any third protective component 170 further includes a second seal 176, the two sides of which are respectively attached to the protective cover 174 and the second shielding component 172.

[0112] In this embodiment, the structure of the third protective component 170 is further defined. The third protective component also includes a second seal 176, which seals the gap between the protective cover 174 and the second shielding component 172. Specifically, the second seal 176 is located between the protective cover 174 and the second shielding component 172, and both sides of the second seal 176 are respectively in contact with the protective cover 174 and the second shielding component 172. In this way, the gap between the protective cover 174 and the second shielding component 172 can be sealed by the second seal 176, preventing liquid from flowing to the current collector arm 140 through the gap between the protective cover 174 and the second shielding component 172.

[0113] The second seal 176 can be made of a material with a certain degree of elasticity so that the second seal 176 has a good sealing effect. For example, the second seal 176 can be a rubber gasket.

[0114] By providing a second seal 176 between the protective cover 174 and the second shielding assembly 172, liquid can be prevented from seeping into the current collector arm 140 from the gap between the protective cover 174 and the second shielding assembly 172, thereby improving the protective effect of the third protective assembly 170.

[0115] In one possible embodiment, the anti-drip structure for the moving parts of the mother car proposed in this utility model mainly consists of three parts: a wheel bearing protective cover assembly (i.e., the first protective assembly 150), a guide wheel protective cover (i.e., the second protective assembly 160), and a current collector arm protective cover assembly (i.e., the third protective assembly 170), such as Figure 1 As shown, each component is bolted to the chassis of the mother car in the mother car (i.e., shuttle car).

[0116] The wheel bearing protective cover assembly consists of a wheel cover (i.e., bearing shield 151), a bearing protective cover (i.e., drive shaft shield 152), and a first waterproof gasket (i.e., first seal 153). There are four sets of wheel bearing protective cover assemblies, distributed at the four wheels 122 respectively. Figure 1 , Figure 2 and Figure 3 As shown. Wheel covers and bearing guards are installed on both sides of the main beam 114, with a first waterproof pad added in the middle, together covering the bearing 121 and protecting the mating surfaces of the bearing 121 and the shaft (i.e., the drive shaft 180) from water droplets.

[0117] The guide wheel protective cover consists of symmetrical left and right components, distributed at three guide wheels 130, and mounted on the anti-jump plate (i.e., the second mounting plate 112). The bottom of the guide wheel protective cover (i.e., the base plate 162) has a certain slope. Water droplets splashed out by the guide wheels 130 during operation flow down the slope, preventing water from splashing onto the sliding contact line 113 and the barcode tape. Figure 4 and Figure 5 As shown.

[0118] The current collector arm protective cover assembly consists of a front protective cover (i.e., protective cover 174), a rear protective cover (i.e., second protective component 160), a protective cover support frame (i.e., support member 173), and a second waterproof gasket (i.e., second sealing member 176). During installation, first fix the front protective cover to the protective cover support frame, then install it onto the current collector arm mounting bracket 115. Next, attach the second waterproof gasket to the top of the rear protective cover, and finally install it onto the front protective cover to form a complete current collector arm protective cover assembly. The upper surface of the front protective cover is sloped, causing water droplets to flow downwards, thus preventing water droplets from affecting the current collector arm 140. Figure 6 , Figure 7 and Figure 8 As shown.

[0119] The above protective structure effectively protects the moving parts of the mother car. Combined with the protective structures of other components, the mother car achieves a drip-proof effect, enabling it to operate stably and efficiently in a dripping warehouse environment.
