[0002] The outer shell of the robot chassis is generally made of plastic injection molding, and an anti-collision strip is set on the outer shell of the chassis. In other words, the outer shell of the chassis needs to have a high structural strength to withstand the external pressure to cause the anti-collision strip to deform. However, if the wall thickness of the outer shell of the chassis is too thick, many appearance defects will occur and the production yield will be low. In addition, in order to enhance the visual experience of the robot, the chassis often adds lighting effects, and the light strip also needs to be set on the chassis, making the chassis structure difficult to layout. Utility Model Content

[0003] The purpose of the embodiments of the utility model is to provide a robot chassis structure and a robot to solve the technical problems existing in the prior art that the chassis shell is too thick, the production yield is low, and the chassis structure is difficult to layout.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a robot chassis structure, including an outer shell structure, a chassis body, a light bar bracket and a light bar body, the light bar bracket is arranged between the outer shell structure and the chassis body, the light bar bracket has an outer edge portion and an inner edge portion, at least a portion of the outer edge portion abuts against the outer shell structure, at least a portion of the inner edge portion abuts against the chassis body, and the light bar body is installed on the light bar bracket.

[0005] In the above scheme, the robot chassis structure includes a shell structure, a chassis body, a light bar bracket and a light bar body. The light bar body can emit light, and the light bar body is installed on the light bar bracket. The light bar bracket has an outer edge and an inner edge. The outer edge of the light bar bracket abuts against the shell structure, and the inner edge of the light bar bracket abuts against the chassis body to improve the support force of the shell structure, that is, the anti-collision ability of the shell structure can be increased without increasing the thickness of the shell structure. At the same time, the light bar bracket also provides an installation position for the light bar body, simplifies the structural parts of the chassis, and is simple and convenient to install.

[0006] Optionally, the light bar bracket includes a first surround, a second surround, and a connecting portion connecting the first surround and the second surround, the outer edge portion is arranged on the side of the first surround facing the outer shell structure, the second surround is arranged on the side of the first surround facing the chassis body, an installation gap is formed between the first surround and the second surround, and the light bar body is arranged in the installation gap.

[0007] In the above scheme, since an installation gap is formed between the first surrounding edge and the second surrounding edge, the light bar bracket can be stably installed in the light bar bracket, and the first surrounding edge can shield the light bar body so that the light emitted by the light bar body can only hit the bottom of the robot and not toward the side of the outer shell structure. Therefore, the light leakage of the light bar body at the outer shell structure can be reduced.

[0008] Optionally, the robot chassis structure further includes a light diffuser, which is used to press the light bar body into the installation gap, and the light diffuser is fixedly connected to the light bar bracket.

[0009] In the above scheme, by setting the light uniforming member, firstly, the light emitted by the light bar body can be made more uniform and softer, and secondly, it can be used as a pressure plate to fix the light bar body, thereby reducing the number of parts in the robot chassis structure and reducing the difficulty of installation.

[0010] Optionally, the first surrounding edge has a first nut column, the second surrounding edge has a second nut column, the first nut column and the second nut column are respectively arranged on opposite sides of the light bar body; the light homogenizing member is provided with a plurality of connection holes respectively facing the first nut column and the second nut column.

[0011] In the above scheme, by respectively setting the first nut and the second nut column on both sides of the light bar body, the pressure connection of the light uniforming member to the light bar body is more stable, and the opposite sides of the light bar body have a connecting and fixing structure to prevent the light bar body from shaking in the installation gap. In addition, the first nut column and the second nut column can also abut against the opposite sides of the light bar body respectively to form a limit for the light bar body, replacing the limit structure of the light bar body in the horizontal direction.

[0012] Optionally, the connecting portion is provided with a cable hole for the cable of the light bar body to pass through.

[0013] In the above solution, the provision of the cable holes enables the cables on the light bar body to be smoothly routed to the power supply structure, which is beneficial to the wiring of the robot chassis structure.

[0014] Optionally, the chassis body includes a first top plate and a first concave-convex structure extended from the first top plate, the connecting portion extends toward one side of the chassis body to form the inner edge portion, the inner edge portion has a second concave-convex structure, the first concave-convex structure and the second concave-convex structure abut against each other, and the top plate and the connecting portion are connected and fixed to each other.

[0015] In the above scheme, the first concave-convex structure can enhance the structural strength of the chassis body, and the space formed in the first concave-convex structure can be used to install universal wheels, fixed wheels, counterweights and other components, and the contact area with the inner edge can be enhanced to better transmit the impact force. The second concave-convex structure can enhance the structural strength of the light bar bracket, and the contact area with the chassis body can be enhanced to better transmit the impact force.

[0016] Optionally, the outer shell structure includes a second top plate and a third surrounding edge extending from the second top plate, and the third surrounding edge abuts against the outer edge portion.

[0017] In the above scheme, by setting the third surround and the outer edge portion to abut against each other, when the third surround is subjected to impact force, the impact force will gradually dissipate along the force transmission path from the third surround, the first surround, the connecting portion to the chassis body, thereby reducing the impact on the third surround and lowering the structural strength requirements for the third surround.

[0018] Optionally, an anti-collision strip is fixedly provided on the outer side of the third surrounding edge.

[0019] In the above solution, the anti-collision strip can be a standard part and is arranged on the outside of the shell structure. In this way, the cost of the anti-collision strip is low, reducing the design cost.

[0020] Optionally, the number of the light bar brackets and the number of the light bar bodies are both two, and the two light bar brackets are respectively arranged on opposite sides of the chassis body.

[0021] In the above scheme, the chassis body has a relatively set front end and rear end, and the chassis body is relatively large. Generally, it is only necessary to set the light bar body at the front end and rear end of the chassis body. Therefore, the number of light bar bodies is two, and the number of light bar brackets is also two. One light bar bracket corresponds to one light bar body.

[0022] The utility model also provides a robot, comprising the above-mentioned robot chassis structure.

[0023] In the above scheme, the robot chassis structure includes a shell structure, a chassis body, a light bar bracket and a light bar body.

At the same time, the light bar bracket also provides an installation position for the light bar body, simplifies the structural parts of the chassis, and is simple and convenient to install.

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] The outer shell of the robot chassis is generally made of plastic injection molding, and an anti-collision strip 50 is set on the outer shell of the chassis. In other words, the outer shell of the chassis needs to have a high structural strength to withstand the external pressure to cause the anti-collision strip 50 to deform. However, if the wall thickness of the outer shell of the chassis is too thick, many appearance defects will occur and the production yield will be low. In addition, in order to enhance the visual experience of the robot, the chassis often adds lighting effects, and the light strip also needs to be set on the chassis, making the chassis structure difficult to layout.

[0040] At present, the anti-collision strips on the outer shell of the chassis of many robots on the market are non-standard designs. According to the product appearance of the robot, a layer of soft rubber is designed on the outer shell of the chassis, and pressure sensors and other devices are installed inside as anti-collision trigger devices. This kind of rubber-encapsulated design has a high cost and is more difficult to maintain in the later stage. At the same time, a bottom shell is also required to cover the bottom of the chassis for protection. Many chassis lights often use PCBA light boards designed according to their own external dimensions, which is very expensive. The light board is installed and fixed on the structural parts of the chassis, and a light-distributing part is added, which also needs to be fixed on the structural parts. This design has many structural parts, complex installation, and high cost.

[0041] In order to alleviate the above-mentioned technical problems, the utility model proposes a robot chassis structure and a robot, including an outer shell structure 30, a chassis body 20, a light bar bracket 11 and a light bar body 12. The light bar bracket 11 is used to install the light bar body 12, and provides an installation position for the light bar body 12. It only needs to be connected with the outer shell structure 30, the chassis body 20, etc. through the light bar bracket 11, thereby reducing the number of structural parts. During installation, the light bar body 12 and other related structures can also be first installed on the light bar bracket 11 to form an assembly component, and then assembled to the robot. The installation steps are also relatively simple. At the same time, the light bar bracket 11 is arranged between the outer shell structure 30 and the chassis body 20, the outer edge of the light bar bracket 11 abuts against the outer shell structure 30, and the inner edge of the light bar bracket 11 abuts against the chassis body 20. When the outer shell structure 30 is impacted, the impact force can be transmitted along the path of the outer shell structure 30, the light bar bracket 11 and the chassis body 20, reducing the influence of the impact force on the outer shell structure 30, and indirectly improving the ability of the outer shell structure 30 to withstand the impact force. Even when the outer shell structure 30 is thin, it can withstand the impact. Therefore, the outer shell structure 30 can be set as a thinner structural member to improve the production yield of the outer shell structure 30.

[0042] The robot chassis structure provided by the embodiment of the utility model is now described.

[0043] Please also read Figures 1 to 4 The robot chassis structure includes an outer shell structure 30, a chassis body 20, a light bar bracket 11 and a light bar body 12. The light bar bracket 11 is arranged between the outer shell structure 30 and the chassis body 20. The light bar bracket 11 has an outer edge and an inner edge. At least part of the outer edge abuts against the outer shell structure 30, and at least part of the inner edge abuts against the chassis body 20. The light bar body 12 is installed on the light bar bracket 11.

[0044] The outer shell structure 30 is a structure close to the outer side of the robot chassis structure, and at least a portion of the outer side of the outer shell structure 30 is the appearance surface of the robot chassis structure. The anti-collision structure is generally arranged on the outer side of the outer shell structure 30 .

[0045] The chassis body 20 is the main structure of the robot chassis structure. When the robot is a wheeled robot, the roller assembly 40 and other structures are installed at the chassis body 20. The chassis body 20 is generally arranged inside the shell structure 30. The chassis body 20 can be a metal structure, so that its structural strength is greater and the reliability of the chassis structure is increased.

[0046] The light bar bracket 11 is arranged between the shell structure 30 and the chassis body 20. The light bar bracket 11 has an outer edge and an inner edge. Part or all of the outer edge abuts against the shell structure 30, and part or all of the inner edge abuts against the chassis body 20. In this way, when an external force hits the shell structure 30, the shell structure 30 is subjected to force. Since the shell structure 30, the light bar bracket 11 and the chassis body 20 abut against each other, the force received by the shell structure 30 is transmitted to the chassis body 20 via the light bar bracket 11, so that part of the impact force is borne by the light bar bracket 11 and the chassis body 20. Therefore, the shell structure 30 can be set as a relatively thin-walled structure, so that the production yield of the shell structure 30 is improved and the production cost is reduced.

[0047] The light bar body 12 is a light-emitting component. After the light bar body 12 is connected to electricity, it can emit light to improve the visual experience of the robot. The light bar body 12 is installed on the light bar bracket 11. During installation, the light bar body 12 and other related structures can be first installed on the light bar bracket 11 to form an assembly component, and then assembled to the robot. The installation steps are also relatively simple. In this way, the light bar bracket 11 can not only enhance the ability of the outer shell structure 30 to withstand impact, but also be used as a mounting structure for the light bar body 12, thereby reducing the number of parts of the robot chassis structure, and the installation of the light bar body 12 is also relatively convenient.

[0048] The robot chassis structure in the above embodiment includes a shell structure 30, a chassis body 20, a light bar bracket 11 and a light bar body 12. The light bar body 12 can emit light. The light bar body 12 is installed on the light bar bracket 11. The light bar bracket 11 has an outer edge and an inner edge. The outer edge of the light bar bracket 11 abuts against the shell structure 30, and the inner edge of the light bar bracket 11 abuts against the chassis body 20 to improve the support force of the shell structure 30, that is, the anti-collision ability of the shell structure 30 can be increased without increasing the thickness of the shell structure 30. At the same time, the light bar bracket 11 also provides an installation position for the light bar body 12, simplifies the structural parts of the chassis, and is simple and convenient to install.

[0049] In some embodiments of the present invention, please refer to Figures 1 to 3The light bar bracket 11 includes a first surround 111, a second surround 112 and a connecting portion 113 connecting the first surround 111 and the second surround 112. The outer edge is arranged on the side of the first surround 111 facing the shell structure 30, and the second surround 112 is connected to the side of the first surround 111 facing the chassis body 20. An installation gap is formed between the first surround 111 and the second surround 112, and the light bar body 12 is arranged in the installation gap.

[0050] The light bar bracket 11 includes a first surrounding edge 111, a second surrounding edge 112 and a connecting portion 113. The side of the first surrounding edge 111 facing the outer shell structure 30 can be called the outer edge of the light bar bracket 11, that is, at least part of the first surrounding edge 111 abuts against the outer shell structure 30. The second surrounding edge 112 is arranged on the side of the first surrounding edge 111 facing the chassis body 20, which can also be understood as the second surrounding edge 112 being arranged on the side of the first surrounding edge 111 facing away from the outer edge. The first surrounding edge 111 and the second surrounding edge 112 are connected by the connecting portion 113, which can be understood as follows: the first surrounding edge 111 and the second surrounding edge 112 are respectively located on opposite sides of the connecting portion 113; the first surrounding edge 111 is located on one side of the connecting portion 113, and the second surrounding edge 112 is located in the middle of the connecting portion 113, that is, the connecting portion 113 extends to cross the second surrounding edge 112; the second surrounding edge 112 is located on one side of the connecting portion 113, and the first surrounding edge 111 is located in the middle of the connecting portion 113, that is, the connecting portion 113 extends to cross the second surrounding edge 112. The first surrounding edge 111 and the second surrounding edge 112 are arranged at intervals, so that an installation gap is formed between the first surrounding edge 111 and the second surrounding edge 112. It can be understood that the side of the first surrounding edge 111 facing the second surrounding edge 112, the side of the second surrounding edge 112 facing the first surrounding edge 111, and the side of the connecting portion 113 enclose the installation gap, so that the light bar body 12 can be inserted into the installation gap.

[0051] Since an installation gap is formed between the first surrounding edge 111 and the second surrounding edge 112, the light bar bracket 11 can be stably installed in the light bar bracket 11, and the first surrounding edge 111 can shield the light bar body 12, so that the light emitted by the light bar body 12 can only hit the bottom of the robot and will not be directed toward the side of the outer shell structure 30. Therefore, the light leakage of the light bar body 12 at the outer shell structure 30 can be reduced.

[0052] In some embodiments, the installation gap surrounded by the first surrounding edge 111, the second surrounding edge 112 and the connecting portion 113 has a U-shaped cross section, that is, a U-shaped groove, and the light bar body 12 can be inserted into the installation gap from the opening end of the U-shaped groove.

[0053] In some embodiments, a first protruding structure is provided on the side of the first surrounding edge 111 facing the second surrounding edge 112. The first protruding structure may be a structure such as tendons, ribs, or bone positions. The first protruding structure is used to abut against the first side of the light bar body 12 to limit the position of the light bar body 12. There may be multiple first protruding structures, which are sequentially spaced along the extension direction of the light bar body 12.

[0054] In some embodiments, a side of the first surrounding edge 111 facing the second surrounding edge 112 contacts a first side of the light bar body 12 to limit the position of the light bar body 12 .

[0055] In some embodiments, a second protruding structure is provided on the side of the second surrounding edge 112 facing the first surrounding edge 111. The second protruding structure may be a structure such as tendons, ribs, or bone positions. The second protruding structure is used to abut against the second side of the light bar body 12 to limit the position of the light bar body 12. There may be multiple second protruding structures, which are sequentially spaced along the extension direction of the light bar body 12.

[0056] In some embodiments, a side of the second surrounding edge 112 facing the first surrounding edge 111 contacts the second side of the light bar body 12 to limit the position of the light bar body 12 .

[0057] In some embodiments, the light bar body 12 can use a standard part of the side-emitting form, and does not require adhesive, and can be directly installed in the above-mentioned installation gap, which can save costs relatively compared to the PCB light board. Among them, the light bar body 12 side-emitting means that after the light bar body 12 is installed in the installation gap, the side of the light bar body 12 facing the ground emits light.

[0058] In some embodiments, the light bar bracket 11 is made of flame-retardant PC+ABS black material. First, it can meet the fire protection requirements of light bar contact with electronic devices. Second, the black light bar bracket 11 can play a shading role, which can ensure that the light-colored shell cannot see light transmission and light leakage. Third, the strength of this material is relatively hard and can play a supporting role.

[0059] In some embodiments, the first surrounding edge 111 and the second surrounding edge 112 are arranged in an arc shape, covering at least one corner of the base body.

[0060] In some embodiments of the present invention, please refer to Figure 1 and Figure 3 The robot chassis structure also includes a light homogenizer 13 , which is used to press the light bar body 12 into the installation gap, and the light homogenizer 13 is fixedly connected to the light bar bracket 11 .

[0061] The function of the light homogenizer 13 is to refract and emit the light emitted by the light bar body 12 so that the light is emitted more evenly and softly. The light homogenizer 13 can be a diffuser. The light homogenizer 13 is arranged on the light-emitting side of the light bar body 12 so that most of the light emitted by the light bar body 12 is emitted after being refracted and reflected by the light homogenizer 13. At the same time, the light homogenizer 13 can also press and fix the light bar body 12 to prevent the light bar body 12 from shaking in the installation gap.

[0062] By setting the light homogenizer 13, firstly, the light emitted by the light bar body 12 can be made more uniform and softer, and secondly, it can be used as a pressure plate to fix the light bar body 12, thereby reducing the number of parts in the robot chassis structure and reducing the difficulty of installation.

[0063] In some embodiments, the light diffuser 13 is fixed to the light bar bracket 11 by means of fixing parts such as screws and bolts. A connection hole is provided on the light diffuser 13, and a nut column is provided on the light bar bracket 11. The fixing part passes through the through hole of the light diffuser 13 and is threadedly connected to the nut column, so that the light diffuser 13 is fixed to the light bar bracket 11. The fixing part used to fix the light diffuser 13 and the light bar bracket 11 can be called a first fixing part 117.

[0064] In some embodiments, the light homogenizer 13 includes two light homogenizer units 131 with the same structure, so as to avoid the light homogenizer 13 being too long. Splitting into two light homogenizer units 131 can reduce the size of the injection mold and reduce the cost. Moreover, when the two light homogenizer units 131 have the same structure, they are made of the same material and can be shared.

[0065] In some embodiments, the light homogenizing member 13 is made of PC milky white semi-transparent material added with diffusion powder, and its flame retardancy meets the fire protection requirements for contact with electronic device light strips, and can achieve a better light homogenizing effect.

[0066] In some embodiments of the present invention, please refer to Figure 1 and Figure 2 The first surrounding edge 111 has a first nut column 115, and the second surrounding edge 112 has a second nut column 116. The first nut column 115 and the second nut column 116 are respectively arranged on opposite sides of the light bar body 12; the light homogenizing member 13 is provided with a plurality of connection holes that are respectively opposite to the first nut column 115 and the second nut column 116.

[0067] There is an installation gap between the first surrounding edge 111 and the second surrounding edge 112, and the first nut column 115 can be integrally formed with the first surrounding edge 111, and the second nut column 116 can be integrally formed with the second surrounding edge 112. The opposite sides of the light bar body 12 face the first surrounding edge 111 and the second surrounding edge 112 respectively, and the first nut column 115 and the second nut column 116 are respectively arranged on the opposite sides of the light bar body 12, so that the light homogenizer 13 has a connection position with the light bar body 12 at least on the opposite sides of the light bar body 12. Specifically, the light homogenizer 13 is connected and fixed to the light bar body 12 by screws, bolts, etc. The light homogenizer 13 is provided with connection holes at least on the opposite sides of the light bar body 12, and some fixing parts are threadedly connected to the first nut column 115 through the connection holes, and the other part of the fixing parts are threadedly connected to the second nut column 116 through the connection holes.

[0068] By respectively arranging the first nut column 115 and the second nut column 116 on both sides of the light bar body 12, the pressure connection of the light uniforming member 13 to the light bar body 12 is more stable, and the opposite sides of the light bar body 12 have a connection and fixing structure to prevent the light bar body 12 from shaking in the installation gap. In addition, the first nut column 115 and the second nut column 116 can also abut against the opposite sides of the light bar body 12, respectively, to form a limit for the light bar body 12, replacing the limit structure of the light bar body 12 in the horizontal direction.

[0069] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 The connecting portion 113 is provided with a cable hole 1131 for the cable of the light bar body 12 to pass through. The light bar body 12 has a cable, and the cable extends to a circuit board or other power supply structure, and the light bar body 12 is powered and illuminated by the cable. Since the light bar body 12 is located inside the installation gap, one end of the cable connected to the light bar body 12 is also located inside the installation gap, and the cable passes through the cable hole 1131 to the outside of the installation gap, that is, to the outside of the light bar bracket 11.

[0070] The arrangement of the cable hole 1131 enables the cables on the light bar body 12 to be smoothly routed to the power supply structure, which is beneficial to the wiring of the robot chassis structure.

[0071] In other embodiments, a cable hole 1131 is disposed on the second surrounding edge 112 , and the cables on the light bar body 12 extend to the outside of the light bar bracket 11 through the cable hole 1131 .

[0072] In some embodiments, the cable hole 1131 is in a circular, oval, oval, or other shape, and its inner wall is smooth to avoid scratching the cable.

[0073] In some embodiments of the present invention, please refer to Figure 4 and Figure 5The chassis body 20 includes a first top plate 21 and a first concave-convex structure 22 extended from the first top plate 21. The connecting portion 113 extends toward one side of the chassis body 20 to form an inner edge portion. The inner edge portion has a second concave-convex structure 114. The first concave-convex structure 22 and the second concave-convex structure 114 abut against each other, and the first top plate 21 and the connecting portion 113 are connected and fixed to each other.

[0074] When the robot chassis structure and the robot are in normal use, the first top plate 21 can be set horizontally or nearly horizontally. The first concave-convex structure 22 is formed by extending the first top plate 21, which can be understood as: the first concave-convex structure 22 is formed by extending the first top plate 21 toward the vertical direction or nearly the vertical direction; the first concave-convex structure 22 can also be formed by extending the first top plate 21 toward the horizontal direction or nearly the horizontal direction. The specific structure of the chassis body 20 is related to the layout of the chassis functional parts of the robot. If the robot is a wheeled robot, the chassis body 20 needs to reserve space to install the roller assembly 40, the counterweight block, etc. The second concave-convex structure 114 is a part of the inner edge. When the first concave-convex structure 22 and the second concave-convex structure 114 abut and cooperate with each other, at least part of the first concave-convex structure 22 and the second concave-convex structure 114 are in a chimeric state.

[0075] The chassis body 20 includes a first concave-convex structure 22, and the inner edge portion includes a second concave-convex structure 114. The first concave-convex structure 22 can be provided to enhance the structural strength of the chassis body 20, and secondly, the space formed in the first concave-convex structure 22 can be used to install components such as universal wheels, shaped wheels, and counterweights, and thirdly, the contact area with the inner edge portion can be enhanced to better transmit the impact force. The second concave-convex structure 114 can be provided to enhance the structural strength of the light bar bracket 11, and secondly, the contact area with the chassis body 20 can be enhanced to better transmit the impact force.

[0076] In some embodiments, the first top plate 21 and the connecting portion 113 are connected and fixed to each other by screws, bolts and other fixings, and the fixings are called second fixings 51. During assembly, the light bar body 12 is first installed in the installation gap of the light bar bracket 11, and then the light homogenizer 13 presses the light bar body 12 and fixes it to the light bar bracket 11. At this point, a light bar assembly is formed, and then the light bar assembly is installed as a whole to the chassis body 20, specifically, it can be connected through the first top plate 21 and the connecting portion 113. Among them, a first connecting hole is provided on the first top plate 21, and a second connecting hole is provided on the connecting portion 113.

[0079] When the robot chassis structure and the robot are in normal use, the second top plate 31 can be set horizontally or nearly horizontally. The third surrounding edge 32 is extended from the top plate, which can be understood as the third surrounding edge 32 extending from the second top plate 31 in the vertical direction or nearly vertical direction. In this way, the outer shell structure 30 can be similar to a cover structure, which is arranged on the periphery of the chassis body 20 and the light bar bracket 11, and at least the surface of the third surrounding edge 32 is the appearance surface of the robot chassis structure. Among them, the third surrounding edge 32 is in contact with the outer edge, that is, the inner wall of the third surrounding edge 32 is in contact with at least part of the outer wall of the first surrounding edge 111, so that the impact force received by the third surrounding edge 32 can be dispersed to the chassis body 20 through the light bar bracket 11.

[0080] By setting the third surround 32 to abut against the outer edge, when the third surround 32 is subjected to impact force, the impact force will gradually dissipate along the force transmission path of the third surround 32, the first surround 111, the connecting portion 113 to the chassis body 20, thereby reducing the impact on the third surround 32 and lowering the structural strength requirements for the third surround 32.
