[0030] To describe in detail the technical content, the achieved objectives and the effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0031] Please refer to Figure 1 and Figure 6 As shown, the present utility model designs a tumbler - type walking robot, which includes: an upper cover body, a lower housing, and a walking mechanism. The above - mentioned upper housing can be covered on the lower housing, and the above - mentioned lower housing can be detachably connected to the walking mechanism.

[0032] Among them, referring to Figure 3 , in actual application, components with relatively light weights such as a camera assembly can be arranged on the upper housing. The camera assembly can be specifically arranged on the upper cover body through a mounting frame. The above - mentioned mounting frame is snap - connected to the upper housing, and the above - mentioned camera assembly is used to shoot and collect image information during the robot's walking.

[0033] In order to improve the stability of the tumbler - type walking robot, the present utility model re - adjusts the weight distribution structure of the robot. Only some components with relatively light masses are arranged on its upper housing, while some components with relatively heavy weights are specifically arranged in the accommodation cavity of the lower housing to lower the center of gravity of the robot.

[0034] Refer to Figure 1 , Figure 2 As shown, in this embodiment, an accommodation cavity is provided in the lower housing of the tumbler - type walking robot to use the accommodation cavity to load some components with relatively heavy weights, such as: a battery.

[0035] In addition, it should be noted that, in order to improve the uniformity of weight distribution while lowering the center of gravity of the robot and realizing the "tumbler" characteristic of the robot, refer to Figure 4 As shown, in this embodiment, a plurality of counterweights are further arranged in the accommodation cavity, and it is controlled that the above - mentioned plurality of counterweights are symmetrically arranged with equal weights with the central axis of the lower housing as the axis of symmetry. When the battery is arranged in the accommodation cavity, the central axis of the battery needs to be collinear with the central axis of the lower housing to ensure reasonable weight distribution.

[0036] Based on this setting, the tumbler - type walking robot can not only achieve uniform weight distribution at both ends of the central axis of the lower housing, but also greatly lower the center of gravity of the robot, realizing the "tumbler" effect and ensuring that there is no problem of tipping over during walking.

[0037] Correspondingly, as Figure 4 and Figure 6As shown, in order to improve the accommodation effect of the above-mentioned battery and multiple counterweight blocks, the present utility model has also optimized and adjusted the cavity structure of the accommodation cavity of the lower housing of the tumbler-type walking robot for "partitioning". Among them, in this embodiment, two protruding portions extending along the length direction of the lower housing are specifically provided in the above-mentioned accommodation cavity. These two protruding portions are symmetrically arranged with the central axis of the lower housing as the axis of symmetry, so as to divide the above-mentioned accommodation cavity into a first cavity, a second cavity, and a third cavity, and the first cavity, the second cavity, and the third cavity are arranged in sequence along the width direction of the lower housing.

[0038] It should be noted that the reason for the partition design of the "cavity" of the accommodation cavity is that: partitioning the accommodation cavity into a first cavity, a second cavity, and a third cavity can ensure that the positioning of the counterweight block and the battery in the cavity where they are accommodated is relatively stable, and there will be no displacement of the counterweight block and the battery in the accommodation cavity due to the inclined walking of the walking robot, thereby affecting the weight distribution in the accommodation cavity.

[0039] As Figure 4 and Figure 6 shown, in actual application, the tumbler-type walking robot of this embodiment is provided with a total of two counterweight blocks, namely a left counterweight block and a right counterweight block. The above-mentioned left counterweight block and the right counterweight block are of equal weight, and the left counterweight block and the right counterweight block are symmetrically accommodated in the first cavity and the third cavity respectively with the central axis of the lower housing as the axis of symmetry; and the above-mentioned battery is detachably arranged in the second cavity in the above-mentioned accommodation cavity.

[0040] Of course, in some preferred embodiments, the staff can select multiple counterweight blocks of different specifications and types according to actual application requirements and accommodate them in the above-mentioned first cavity and the third cavity; but no matter what specifications and weights of counterweight blocks are used, it is necessary to ensure that the total weight of all the counterweight blocks accommodated in the first cavity is the same as the total weight of all the counterweight blocks accommodated in the third cavity.

[0041] Correspondingly, as Figure 4 and Figure 5 shown, in this embodiment, the tumbler-type walking robot further includes: a control circuit board and a locking member. The above-mentioned control circuit board is arranged in the accommodation cavity of the lower housing, and the above-mentioned control circuit board is specifically covered above the battery; among them, through holes are opened on the above-mentioned control circuit board, and the locking member passes through the through holes and is connected to the protruding portion in the accommodation cavity of the lower housing to fix the control circuit board to the lower housing.

[0042] At the same time, in this embodiment, an external thread portion is further provided on the above-mentioned locking member, and two threaded holes that cooperate with the external thread portion of the locking member are respectively provided on the two protruding portions to fix the four top corners of the control circuit board to the lower housing.

[0043] In addition, in this embodiment, considering aesthetics, after the upper cover of the tumbler - type walking robot is covered on the lower housing, the whole is spherical, with a more beautiful and lovely shape, and at the same time, it is easier to avoid obstacles. Additionally, to further improve aesthetics, a groove is provided at the bottom of the lower housing, and the above - mentioned walking mechanism is specifically arranged in the groove to present a posture of being partially embedded in the lower housing; among them, to ensure that the walking mechanism can normally drive the robot to walk, at least part of the walking mechanism needs to extend out of the groove to contact the ground.

[0044] It should be noted that in this utility model, the walking mechanism includes: a motor housing and four driving wheels. The above - mentioned motor housing is detachably connected to the lower housing, and the two can be specifically fixed by buckles. And a motor is provided in the motor housing, and the output shaft of the motor can be respectively drivingly connected to the four driving wheels, and at least part of the driving wheels can be controlled to extend out of the groove to contact the ground. Among them, the walking mechanism further includes a track. Two driving wheels are respectively provided on the left and right sides of the motor housing, and the above - mentioned track surrounds the two driving wheels on one side of the motor housing to form a wheel - type structure, thereby enhancing the obstacle - crossing ability of the tumbler - type walking robot.

[0045] In summary, the tumbler - type walking robot designed by this utility model has good stability. It can avoid tipping over during walking by adjusting the counterweight, thus ensuring normal operation, and has good promotion prospects and application value.

[0046] The above are only the embodiments of this utility model, and do not limit the patent scope of this utility model accordingly. All equivalent transformations made by using the content of the specification and drawings of this utility model, or directly or indirectly applied in related technical fields, are similarly included in the patent protection scope of this utility model.
