Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to an explosion-proof robot. Background Technology

[0002] Explosion-proof robots are mainly used in special fields to replace manual inspections. These robots are equipped with various industry-specific sensors for data collection and intelligent analysis, achieving automation, informatization, and intensification. They largely replace manual labor in completing most inspection tasks, reducing inspection costs, improving inspection efficiency and quality, and preventing harm to the life and health of inspection personnel.

[0003] Currently, explosion-proof robots mainly consist of a movable chassis and components mounted on the chassis, such as lidar, gas sensors, alarm mechanisms, and GPS positioning mechanisms, to achieve functions such as inspection and detection of target sites. Existing chassis include a cabin and multiple drive mechanisms. For example, as shown in patent application number CN202311863039.1, entitled "An Explosion-proof Inspection Robot," the cabin has a cross-like structure, and four drive mechanisms are arranged in a rectangular pattern around the cabin. These drive mechanisms cooperate to achieve the movement of the entire chassis.

[0004] In the aforementioned patent, the cabin is a single-chamber structure. Components that require explosion-proof treatment, such as batteries and motors, are placed inside the cabin. The overall height of the cabin needs to be set in conjunction with the taller components, while some shorter components are suspended in the air, resulting in low space utilization within the cabin. Therefore, the existing cabin structure has a large overall size, which prevents the optimization of the overall vehicle size and is not conducive to the design of a small-volume vehicle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an explosion-proof robot with an improved cabin structure. A new cavity is set inside the existing chamber, which allows for the division of the interior layout within the vertical space. This facilitates the arrangement of various components within the cabin, improving the utilization rate of the internal space. By fully utilizing the internal space, the overall cabin can be designed to be smaller and lighter, thereby optimizing the length and width of the vehicle and contributing to a compact overall vehicle design.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an explosion-proof robot, comprising a cabin, the cabin including a chamber, a cavity body, and a cover plate, wherein the chamber has an opening.

[0007] The cavity body is embedded in the cavity along the opening end of the cavity and is sealed to the opening end of the cavity. The cavity body has an opening, and the cover plate is located at the opening end of the cavity body and is sealed to the cavity body.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This utility model adds a cavity to the existing cabin structure. The cavity and chamber can form an installation space, and the cavity and cover can also form an installation space. The layout and installation are based on the distance between the cavity and chamber and the height of the cavity, combined with the height of each component in the cabin, so as to improve the utilization rate of the cabin's internal space. By making full use of the internal space of the cabin, the overall cabin volume can be reduced and the design can be made relatively light, thereby optimizing the length and width of the vehicle and facilitating the small volume design of the whole vehicle.

[0010] Furthermore, the opening end of the chamber is circular, and the chamber has an annular extension plate adapted to the opening end of the chamber. The annular extension plate is mounted on the opening end of the chamber and is sealed to the chamber.

[0011] Furthermore, the cavity sidewall has an annular surrounding plate segment that fits into the inner wall of the cavity opening end, and an annular extension plate extends outward along the upper part of the annular surrounding plate segment.

[0012] Furthermore, the opening end of the cavity is circular, and the cover plate has an annular connecting plate adapted to the opening end of the cavity. The annular connecting plate is mounted on the opening end of the cavity and is sealed to the cavity.

[0013] Furthermore, the cover plate is provided with an annular mounting plate extending toward the cavity, the annular mounting plate fitting against the inner wall of the opening end of the cavity, and an annular connecting plate extending outward along the upper middle part of the annular mounting plate.

[0014] Furthermore, the cavity has a stepped groove structure facing the interior of the cavity, so that the cavity has connecting cavities and mounting cavities arranged vertically.

[0015] Furthermore, the mounting cavity has a rectangular cavity structure.

[0016] Furthermore, the chamber has an upper cavity and a lower cavity that are connected vertically. Both the upper cavity and the lower cavity are rectangular cavity structures. The two side walls along the length direction of the upper cavity are flush with the corresponding two side walls of the lower cavity. The two side walls along the width direction of the upper cavity contract inward to form a stepped cavity structure between the upper cavity and the lower cavity.

[0017] Furthermore, the two side walls of the chamber along the length of the upper cavity are respectively provided with outwardly protruding auxiliary structures, so that the chamber has two oppositely arranged and outwardly protruding auxiliary cavities.

[0018] Furthermore, reinforcing structures are provided at the bottom of the outer chamber, the bottom of the outer chamber, and the bottom of the inner side of the cover plate. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] like Figure 1-9 As shown, an explosion-proof robot includes a cabin 100, which includes a chamber 110, a cavity 120, and a cover plate 130. The chamber 110 has an opening, and the cavity 120 is embedded in the chamber 110 along the opening end and is sealed to the opening end of the chamber 110. The cover plate 130 is located at the opening end of the cavity 120 and is sealed to the cavity 120.

[0031] Understandably, the chamber 110 in this application is equivalent to the cabin 100 in the prior art. Therefore, the overall structure of the chamber 110 can be a common rectangular box structure, a cylindrical box structure, or other irregular structures, such as the cross-shaped structure described in the applicant's previous patent application with patent number CN202311863039.1. The structure of the chamber 110 can be designed based on components such as the drive mechanism mounted on the explosion-proof robot. Regardless of the structure of the chamber 110, the cavity 120 can be inserted into the chamber 110 to separate the internal structure of the chamber 110. Correspondingly, the cavity 120 can also adopt various structures, preferably a structure adapted to the components (batteries, etc.) to be placed. The chamber 110 and the cavity 120 can achieve a sealed connection, thereby making the installation space between the chamber 110 and the cavity 120 also have a sealed effect, which conforms to the sealed design of the robot cabin 100. Similarly, the cover plate 130 and the cavity 120 can form a sealed chamber 110 to meet the sealing design of the cabin 100.

[0032] Based on the existing cabin 100 structure, this utility model adds a cavity 120. The cavity 120 and the chamber 110 can form an installation space, and the cavity 120 and the cover plate 130 can also form an installation space. According to the distance between the cavity 120 and the chamber 110 and the height inside the cavity 110, the layout and installation are combined with the height of each component inside the cabin 100 to improve the utilization rate of the internal space of the cabin 100. By making full use of the internal space of the cabin 100, the overall volume of the cabin 100 can be reduced and the design can be made relatively light, thereby optimizing the length and width of the whole vehicle and facilitating the small volume design of the whole vehicle.

[0033] Currently, the opening on the cabin 100 (equivalent to the opening on the chamber 110 in this application) is a rectangular chamber 110. Correspondingly, the opening end of the cabin 100 needs to be sealed using a rectangular plate. The rectangular sealing surface needs to be milled, ground, and processed to ensure the straightness of the four sides and the perpendicularity of adjacent sides (the 90° error needs to be controlled within 0.1°). Otherwise, "uneven sealing surface" (such as a protrusion on one side) will occur, resulting in higher requirements for the overall structure's processing technology. Furthermore, the sealing effect may suffer from problems such as local sealing surfaces not fitting properly (such as excessive gap at the midpoint of the long side), leading to poor sealing performance. Therefore, this utility model, based on this, limits the structure of the opening end of the chamber 110, such as... Figure 5 , 6As shown in Figure 7, chamber 110 has a circular opening end, which also has an outwardly extending annular connecting end 115 to facilitate the connection between chamber 110 and cavity 120. Correspondingly, cavity 120 has an annular extension plate 123 adapted to the opening end of chamber 110. The annular extension plate 123 is mounted on the connecting end 115 of chamber 110 and is sealed to the connecting end 115 of chamber 110. The connection between the annular extension plate 123 and the opening end of chamber 110 is similar to a flange connection structure. Using sealing rings, multiple locking bolts, etc., a sealed connection between the annular extension plate 123 and the opening end of chamber 110 can be achieved. This connection method has a better sealing effect than the existing rectangular opening connection method, which can increase the sealing and explosion-proof effect of the entire vehicle.

[0034] To facilitate the positioning and insertion of the opening end of chamber 110 and cavity 120, such as... Figure 5 , 6 As shown, the cavity 120 of this application has an annular surrounding plate segment 124 that conforms to the inner wall of the opening end of the cavity 110, and an annular extension plate 123 extends outward along the upper part of the annular surrounding plate segment 124. The annular surrounding plate segment 124 is inserted into the inner wall of the opening end of the cavity 110, which can conform to the opening end of the cavity 110 and limit the annular extension plate 123 so as to connect the annular extension plate 123 and the opening end of the cavity 110.

[0035] Similarly, the connection structure between cavity 120 and cover plate 130 is similar to the connection structure between cavity 120 and chamber 110 to improve the sealing connection effect. Correspondingly, such as Figure 4 , 5 As shown in Figures 6 and 7, the opening end of the cavity 120 is circular, and the cover plate 130 has an annular connecting plate 131 that is adapted to the opening end of the cavity 120. The annular connecting plate 131 is mounted on the opening end of the cavity 120 and is sealed to the cavity 120. The connection between the annular connecting plate 131 and the opening end of the cavity 120 is similar to a flange connection structure. By using sealing rings, multiple locking bolts, etc., a sealed connection between the annular connecting plate 131 and the opening end of the cavity 120 can be achieved.

[0036] Correspondingly, to achieve the positioning connection between the cover plate 130 and the cavity 120, such as Figure 5 , 6 As shown in Figure 7, this application provides an annular mounting plate 132 extending toward the cavity 120 on the cover plate 130. The annular mounting plate 132 fits against the inner wall of the opening end of the cavity 120, and the annular connecting plate 131 extends outward along the upper part of the annular mounting plate 132. The annular mounting plate 132 facilitates the positioning of the annular connecting plate 131 and the opening end of the cavity 120, so as to connect the locking bolts.

[0037] To accommodate the layout of the components, the cavity 120 of this application has a stepped groove structure facing the interior of the chamber 110, so that the cavity 120 has a connecting cavity 122 and a mounting cavity 121 arranged vertically. The connecting cavity 122 and the mounting cavity 121 can both be cylindrical, rectangular, or any combination of shapes. In this application, for example... Figure 5 , 6 As shown in Figures 7 and 8, in combination with the shape of the battery, the connecting cavity 122 adopts a cylindrical structure that is adapted to the opening end of the cavity 120, and the mounting cavity 121 adopts a rectangular cavity structure that is adapted to the battery.

[0038] Since the battery is raised and fixed within the housing 100, only four drive motors with four drive mechanisms are needed at the bottom of the chamber 110. To facilitate the limiting installation of the drive motors, the chamber 110 of this application has an upper chamber 111 and a lower chamber 112 that are interconnected vertically. Both the upper chamber 111 and the lower chamber 112 have rectangular cavity structures. The two side walls along the length direction of the upper chamber 111 are flush with the corresponding side walls of the lower chamber 112. The two side walls along the width direction of the lower chamber 112 contract inward, so that the upper chamber 111 and the lower chamber 112 form a stepped cavity structure. The lower chamber 112 is a scaled-down version of the existing rectangular cavity structure of the housing 100. This structure is designed to accommodate multiple drive motors as needed. Therefore, two mounting ports 1121 are opened on each side wall of the lower chamber 112. The four mounting ports 1121 are used to facilitate the connection between the output end of the drive motor and the wheel 01.

[0039] The mounting structure of the internal components of chamber 110, such as Figure 4 , 6 As shown in Figures 7, 8, and 9, this application provides outwardly protruding auxiliary structures on both side walls of the chamber 110 along the length of the upper cavity 111, so that the chamber 110 has two oppositely arranged and outwardly protruding auxiliary cavities 114. The auxiliary cavities 114 facilitate the installation and design of components such as charging ports.

[0040] To increase the overall strength of the cabin 100, this application provides reinforcing structures at the bottom outer surface of the chamber 110, the bottom outer surface of the cavity 120, and the bottom inner surface of the cover plate 130. For example... Figure 2 , 5 As shown in Figures 6 and 9, the reinforcing structure consists of multiple staggered reinforcing ribs 113 to enhance the overall explosion-proof effect of the cabin 100.

[0041] Based on the aforementioned cabin 100, this application adjusts the placement of the components of the drive mechanism. The overall structure of the drive mechanism is equivalent to the drive structure described in the applicant's previous patent application, CN202311863039.1. Figure 1 , 2As shown in Figure 3, each has a suspension system, which includes a drive motor (stepper motor, servo motor, etc.), a reducer 203, a wheel 01, a locking block 18, a shock absorber 19, a lower control arm 13, a connecting seat 14, a coupling 15, a moving seat 12, a support frame 11, an upper control arm 16, and other components, which can realize the movement and steering of the wheel 01. The only difference is that the reducer 203 is located outside the cabin 100.

[0042] The exterior of the cabin 100 in this application may also be equipped with alarm mechanisms, sound systems, gas sensors, GPS positioning mechanisms, etc., to ensure that the robot can play its corresponding inspection role during the inspection process. This application does not impose any restrictions.
