Abstract
Description
Technical Field
[0001] The present application relates to the field of robotics technology, and in particular to a chassis and a robot. Background Art
[0002] With the development of robotics technology, robots have been used more and more widely. In robots, the chassis can provide stable support for the robot, enabling the robot to move more stably, and is an important part of the robot.
[0003] The movement of the chassis is generally driven by the driver. Due to the influence of factors such as the heat generated by the driver during continuous operation and the environment in which it is located (for example, the ambient temperature is high), the risk of the driver overheating and shutting down is relatively high. In order to achieve heat dissipation of the driver, the driver can be placed close to the metal shell of the chassis, and the natural circulation of air can be used for heat dissipation, so that the heat generated by the driver can be quickly exchanged to the natural environment to keep its own temperature from overheating. However, when the temperature of the robot's environment is high (for example, when the ambient temperature exceeds 60°C), the relative temperature difference is too small, the thermal gradient is reduced, and the driver cannot be cooled in time. The risk of the driver overheating and shutting down is still relatively high.
[0004] The aforementioned cooling methods were unable to meet the cooling requirements of the driver components. Consequently, chassis using compressed air for cooling began to emerge. This involves injecting compressed air directly into the chassis' metal shell, using the compressed air to absorb heat during decompression to rapidly cool the driver components. However, the chassis' metal shell is not a closed structure. When compressed air is used to cool the driver components, it can escape from any open areas of the shell, disrupting the stability of the application. Utility Model Content
[0005] In view of this, the present application provides a chassis and a robot to solve the problem that the metal shell of the chassis is not a closed structure. When compressed air is used to dissipate heat and cool the driving parts, the gas is ejected from any open part of the metal shell, destroying the stability of the application scenario.
[0006] According to one aspect of the present application, a chassis is provided, comprising a housing, a placement member, an exhaust member, and a drive member, wherein the placement member is disposed within the housing and encloses a storage space, the placement member being provided with a first connection port and a second connection port, both of which are in communication with the storage space, the drive member being disposed within the storage space, and the first connection port being configured to be connected to a compressed air source;
[0007] The exhaust component is connected to the shell, and the exhaust component surrounds an exhaust cavity. The exhaust cavity is provided with an exhaust port connected to the exhaust cavity, and the second connecting port is connected to the exhaust cavity.
[0008] Preferably, there is a gap between the driving member and the inner side wall of the placement member.
[0009] Preferably, the placement member includes a first warehouse body and a second warehouse body, the first warehouse body is connected to the second warehouse body, and the first warehouse body and the second warehouse body are surrounded by the accommodating space.
[0010] Preferably, the chassis further includes a silencer, which is filled in the exhaust cavity and has a porous structure.
[0011] Preferably, the chassis further includes an oil-water separator, the first connection port is connected to the compressed air source via the oil-water separator, and the oil-water separator is located outside the housing.
[0012] Preferably, the exhaust member includes a symmetry plane, and the two parts of the exhaust member located on both sides of the symmetry plane are symmetrical with respect to the symmetry plane;
[0013] The exhaust member is provided with a plurality of exhaust ports, all of which are communicated with the exhaust cavity, and the plurality of exhaust ports are located on the same side of the symmetry plane.
[0014] Preferably, the chassis includes a plurality of placement members and a plurality of driving members, the plurality of placement members correspond one-to-one to the plurality of driving members, and the driving members are arranged in the accommodating spaces enclosed by the placement members corresponding to the driving members.
[0015] Preferably, the chassis also includes a confluence piece, which includes an outflow outlet and multiple inflow inlets, and the multiple inflow inlets are all connected to the outflow outlet. The multiple second connection ports in the multiple placement members correspond one-to-one to the multiple inflow inlets, and the second connection ports are connected to the inflow inlets corresponding to the second connection ports, and the outflow outlet is connected to the exhaust chamber.
[0016] According to another aspect of the present application, a robot is provided, comprising the above-mentioned chassis.
[0017] Preferably, the robot further comprises an operating device, wherein the operating device is connected to the chassis and is located on a side of the exhaust member facing away from the exhaust port.
[0018] When the chassis of the present application is in use, a compressed gas source can provide compressed gas, allowing the compressed gas to enter the storage space through the first connection port and then be discharged from the storage space through the second connection port. The compressed gas is then discharged from the chassis through the exhaust cavity and the exhaust port. In this way, when the compressed gas flows through the storage space, it releases pressure and absorbs heat, removing heat generated by the driver within the storage space, thereby achieving heat dissipation and cooling of the driver. The chassis can only be exhausted through the exhaust port, preventing gas from being discharged from locations other than the exhaust port, thereby preventing gas from being ejected from any open areas of the metal shell, which could damage the stability of the application scenario.

However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, except for operations that must occur in a particular order, changes may be made that will be apparent upon understanding the disclosure of this application. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity.
[0027] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent upon understanding the disclosure of this application.
[0028] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, it may be directly “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on,” “directly connected to,” “directly coupled to,” “directly over,” or “directly covering” another element, there may be no other elements intervening therebetween.
[0029] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.
[0030] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are used only to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Thus, a first member, component, region, layer, or portion in the examples described herein may also be referred to as a second member, component, region, layer, or portion without departing from the teachings of the examples.
[0031] For ease of description, spatial relational terms such as "above," "upper," "below," and "lower" may be used herein to describe the relationship of one element to another element as shown in the accompanying drawings.

For example, if the device in the accompanying drawings is turned over, an element described as being "above" or "upper" relative to another element would subsequently be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations "above" and "below," depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly.

[0033] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include changes in shapes that occur during manufacturing.
[0034] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.
[0035] According to one aspect of the present application, a chassis is provided, such as Figures 1 to 4 As shown, the chassis includes an outer shell 2, a placement member 3, an exhaust member 6 and a driving member 4. The exhaust member 6 is arranged on the outer wall of the outer shell 2, the placement member 3 encloses an accommodating space, and the placement member 3 is provided with a first connecting port and a second connecting port, both of which are connected to the accommodating space. The driving member 4 is arranged in the accommodating space, and the first connecting port is used to connect to the compressed air source 11; the exhaust member 6 encloses an exhaust cavity, and the exhaust cavity is provided with an exhaust port 621 connected to the exhaust cavity, and the second connecting port is connected to the exhaust cavity.
[0036] When the chassis of the present application is in use, the compressed gas source 11 can provide compressed gas, allowing the compressed gas to enter the storage space through the first connection port and then be discharged from the storage space through the second connection port. The compressed gas is then discharged from the chassis through the exhaust cavity and exhaust port 621. In this way, when the compressed gas flows through the storage space, it releases pressure and absorbs heat, removing the heat generated by the driver 4 within the storage space, thereby achieving heat dissipation and cooling of the driver 4. The chassis can only be exhausted through the exhaust port 621, preventing gas from being discharged from locations other than the exhaust port 621, thereby preventing gas from being ejected from any open areas of the metal shell, which could damage the stability of the application scenario.
[0037] In the embodiments of the present application, Figure 2 As shown, the placement member 3 includes a first bin body 31 and a second bin body 32 , which are connected to form a receiving space, thereby placing the driving member 4 in the receiving space.
[0038] It should be noted that, in order to facilitate the illustration of the relative positions of the placement member 3 and the driving member 4, Figure 1 The part of the placement piece 3 in is hidden.
[0039] Alternatively, the driving member 4 may be a structure capable of driving the wheels 8 to rotate. For example, the driving member 4 may be a motor. In this case, the second housing 32 may be provided with a hole for extending the output shaft of the power supply, so that a portion of the output shaft of the motor extends from the accommodation space. Alternatively, the second housing 32 may be provided with a threaded hole, and the housing of the driving member 4 may be provided with a matching threaded hole. The second housing 32 and the driving member 4 may then be secured to each other using screws. The second housing 32 may be secured to the housing 2 using the screws.
[0040] Preferably, the first bin body 31 and the second bin body 32 are detachably connected by bolts, so that the driving member 4 can be installed inside the first bin body 31 and the second bin body 32 .
[0041] Furthermore, the placement member 3 includes a first joint 33 and a second joint 34. The first joint 33 is integrally formed with the first chamber body 31, and the second joint 34 is integrally formed with the second chamber body 32. The first joint 33 has a first connection port formed therein, and the second joint 34 has a second connection port formed therein, so that both the first connection port and the second connection port are in communication with the accommodation space.
[0042] In addition, there is a gap between the driving member 4 and the inner wall of the placement member 3, thereby ensuring that the compressed gas entering the accommodating space through the first connecting port can flow to the second connecting port through the gap between the driving member 4 and the inner wall of the placement member 3, thereby achieving heat dissipation of the driving member 4.
[0043] Preferably, when the driver 4 is installed in the accommodation space of the placement member 3, the heat-generating components in the driver 4 are located between the first connection port and the second connection port to ensure heat dissipation of the driver 4. Optionally, when the driver 4 is a motor, the windings and iron core of the motor are located between the first connection port and the second connection port.
[0044] like Figure 1 and Figure 3 As shown, the housing 2 is provided with an adapter plate 7, which can be fixed to the outer wall of the housing 2 by bolts. The housing 2 is provided with a first hole, and the adapter plate 7 is provided with a second hole, the first hole communicating with the second hole. The exhaust member 6 is a hollow structure, and the exhaust member 6 has an opening formed on the side facing the adapter plate 7. The exhaust member 6 is fixed to the adapter plate 7 so that the first hole and the second hole communicate with the exhaust cavity enclosed by the exhaust member 6. The first hole in the housing 2 can communicate with the second connecting port, so that the gas flowing out of the second connecting port of the placement member 3 can enter the exhaust cavity and be discharged through the exhaust port 621.
[0045] Furthermore, the exhaust part 6 may include a connecting portion 61 and an exhaust portion 62, the connecting portion 61 and the exhaust portion 62 may be integrally formed, the connecting portion 61 and the exhaust portion 62 may both be hollow cylindrical structures, the axis of the connecting portion 61 and the axis of the exhaust portion 62 are collinear, the outer diameter of the connecting portion 61 is larger than the outer diameter of the exhaust portion 62, the internal space of the connecting portion 61 and the internal space of the exhaust portion 62 together constitute an exhaust cavity, an exhaust port 621 is provided on the exhaust portion 62, the connecting portion 61 is connected to the adapter plate 7, so that the second hole on the adapter plate 7 is connected to the exhaust cavity.
[0046] Optionally, the connecting portion 61 can be welded to the adapter plate 7, or a transfer tube can be welded to the adapter plate 7. The transfer tube is a hollow structure with threads on the outer wall of the transfer tube and threads on the inner wall of the connecting portion 61. The exhaust component 6 is fixed by matching the threads on the transfer tube with the threads on the connecting portion 61.
[0047] In addition, the exhaust member 6 may include a symmetry plane, the axis of the connecting portion 61 and the axis of the exhaust portion 62 are both located on the symmetry plane, the two parts of the connecting portion 61 located on either side of the symmetry plane are symmetrical about the symmetry plane, and the two parts of the exhaust portion 62 located on either side of the symmetry plane are symmetrical about the symmetry plane. The exhaust portion 62 of the exhaust member 6 is provided with a plurality of exhaust ports 621, and the plurality of exhaust ports 621 are all connected to the exhaust cavity, and the plurality of exhaust ports 621 are located on the same side of the symmetry plane. In other words, the exhaust port 621 is provided on only one of the two parts of the exhaust portion 62 located on either side of the symmetry plane. In this way, the plurality of exhaust ports 621 are located on the same side of the exhaust member 6, which can prevent gas from escaping and destroying the stability of the application scenario.
[0048] Preferably, when the operating device 9 is mounted on the chassis, Figure 5 As shown, one of the two parts located on both sides of the symmetry plane faces the operating device 9, and the other part faces away from the operating device 9. An exhaust port 621 is provided on the part facing away from the operating device 9 to prevent gas from being discharged toward the operating device 9, thereby avoiding affecting the operating device 9.
[0049] The chassis also includes a multi-porous muffler, which fills the exhaust cavity. This porous structure disperses the gas, preventing it from forming a high-speed airflow, thereby reducing noise. Furthermore, reducing the gas flow rate also reduces the impact of the gas on the operating device 9 mounted on the chassis.
[0050] Optionally, the sound-absorbing member may be a porous structure of metal or ceramic material.
[0051] In an embodiment of the present application, the chassis also includes an oil-water separator 12, which is located outside the outer shell 2. The compressed air source 11 is connected to the oil-water separator 12 through a conduit. The oil-water separator 12 can separate water and oil in the compressed gas flowing through, thereby performing preliminary purification of the compressed air.
[0052] Furthermore, the specific number of drive members 4 can be selected based on the number of power sources required for the chassis' drive mode. For example, the number of drive members 4 can be one, two, or four. The number of placement members 3 in the chassis is the same as the number of drive members 4 in the chassis. The placement members 3 correspond to the drive members 4 one-to-one, and the drive members 4 are arranged in the accommodation spaces enclosed by the corresponding placement members 3. Preferably, there are two drive members 4, one of which can drive the two wheels 8 on the same side, and the other drive member 4 drives the two wheels 8 on the other side. The entire chassis is driven by a differential drive method.
[0053] When the number of driving members 4 is more than one, the chassis also includes a conduit 5, which is arranged inside the shell 2. The conduit 5 includes an outflow outlet and multiple inflow inlets, and the multiple inflow inlets are all connected to the outflow outlet. The multiple second connecting ports in the multiple placement members 3 correspond one-to-one to the multiple inflow inlets, and the second connecting ports are connected to the corresponding inflow inlets through a conduit. The outflow outlet is connected to the first hole on the shell 2 through the conduit, so that the outflow outlet is connected to the exhaust chamber.
[0054] Preferably, the manifold 5 can be a pipe connector, and its specific form can be selected based on the number of driving members 4. When the number of driving members 4 is two, the manifold 5 can be a three-way joint, and when the number of driving members 4 is four, the manifold 5 can be a five-way joint.
[0055] like Figure 4As shown, the chassis also includes a flow regulating valve 13. When the number of the driving member 4 is one, the two ends of the flow regulating valve 13 are respectively connected to the oil-water separator 12 and the first connecting port through a conduit to regulate the flow of the compressed gas entering the accommodating space. When the number of driving members 4 is more than one, the chassis also includes a pipe connector, which can be arranged inside the shell 2. The pipe connector includes an inlet and an outlet equal to the number of driving members 4. The number of flow regulating valves 13 can be one or the same as the number of driving members 4. When the number of flow regulating valves 13 is one, one end of the flow regulating valve 13 is connected to the oil-water separator 12 through a conduit, and the other end of the flow regulating valve 13 can be connected to the inlet of the pipe connector. The multiple outlets of the pipe connector are respectively connected to the first connecting ports of the multiple placement members 3 that accommodate the multiple driving members 4, thereby supplying compressed gas to the accommodation space of the multiple placement members 3; when the number of flow regulating valves 13 is the same as the number of driving members 4, the inlet of the pipe connector is connected to the oil-water separator 12 through a conduit, and the multiple outlets of the pipe connector are respectively connected to the multiple flow regulating valves 13, and the flow regulating valve 13 is connected to the first connecting port of the placement member 3, thereby supplying compressed gas to the accommodation space of the multiple placement members 3.
[0056] According to another aspect of the present application, a robot is provided, which includes the above-mentioned chassis and has the same technical effects as the above-mentioned chassis, which will not be repeated here.
[0057] Furthermore, the operating device 9 is mounted on the chassis, so that the chassis can carry the operating device 9 and drive the operating device 9 to move.
[0058] Optionally, the operating equipment 9 includes welding equipment, grinding equipment, cutting equipment, etc.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
