Since the shell drives the rotation of the projection assembly, the expandability is low. CONTENT OF THE UTILITY MODEL

[0003] The projection robot disclosed by the embodiments of the present application can keep the shell stationary while the projection assembly is pitching and rotating to adjust the projection direction of the projection assembly, and has high expandability.

[0004] To achieve the above-mentioned purpose, on one hand, the present application discloses a projection robot, comprising:

[0005] A shell is formed with a first opening, and the shell comprises:

[0006] A bottom shell is provided with a driving wheel at the bottom thereof;

[0007] A top shell is connected above the bottom shell, so that the shell is formed in a spherical shape and an inner cavity for accommodating the projection assembly is formed between the top shell and the bottom shell;

During the pitching and rotating process of the inner shell, the projection of the inner shell on the shell covers the first opening. The inner shell is provided with a projection hole for the projection assembly to project outside the inner shell;

[0010] A support is provided in the bottom shell and located on one side of the projection assembly facing the bottom of the inner cavity. The side of the support away from the projection assembly and the bottom of the inner cavity form a spacing with a preset height, so that when the inner shell pitches and rotates relative to the shell, the inner shell at least partially passes through the spacing;

[0011] A battery is provided on one side of the support, and the battery is used to power the projection robot.

[0012] The top shell and the bottom shell are connected to make the shell spherical, the shell is formed with a first opening, and the inner shell in the inner cavity is fixed with the projection assembly, the inner shell can be tilted relative to the shell to make the projection assembly project to different directions through the projection hole of the inner shell, meanwhile, the inner shell can cover the first opening on the shell during the tilting of the projection assembly, which can avoid the foreign matters such as dust from entering the inner cavity of the shell through the first opening, and can shield the projection assembly to avoid the user seeing the projection assembly from the shell through the first opening. Meanwhile, the battery is arranged in the bottom shell for counterweight.

[0013] Further, the support is arranged on the bottom shell, the battery is arranged by the support, the battery can power the projection robot, and a gap with a preset height is formed between the side of the support away from the projection assembly and the bottom of the inner cavity, the gap provides a movement space for the tilting of the inner shell relative to the shell, that is, the inner shell at least partially passes through the gap during the tilting of the inner shell relative to the shell, which can ensure the large-angle tilting of the inner shell and realize the mutual avoidance of the inner shell and the battery to avoid the mutual interference of the inner shell and the battery.

[0014] In some embodiments of the present application, the support comprises:

[0015] The bearing substrate is provided with the battery on the side facing the projection assembly;

[0016] The first positioning part is arranged to extend from the first edge of the bearing substrate in the direction facing the projection assembly;

[0017] The second positioning part is arranged to extend from the second edge of the bearing substrate in the direction facing the projection assembly, and the second edge is the edge of the bearing substrate opposite to the first edge in the first horizontal direction;

[0018] The first positioning part abuts one side of the battery in the first horizontal direction, and the second positioning part abuts the side of the battery away from the first positioning part.

[0019] The first positioning part and the second positioning part are arranged to extend from the first edge and the second edge of the bearing substrate in the direction facing the projection assembly, respectively, and the second edge is arranged opposite to the first edge in the first horizontal direction, so that the first positioning part and the second positioning part abut the two sides of the battery in the first horizontal direction, respectively, while the bearing substrate supports the battery, and the first positioning part and the second positioning part can jointly clamp and fix the battery.

[0020] In some embodiments of this application, the first positioning part is provided with a first connecting part at the end away from the carrier substrate, and the second positioning part is provided with a second connecting part at the end away from the carrier substrate. Both the first connecting part and the second connecting part are connected to the bottom shell, so that the gap is formed between the side of the carrier substrate away from the projection component and the bottom of the inner cavity.

[0021] The projection robot includes a fixing member, with its two ends connected to the first connecting part and the second connecting part, respectively, and the fixing member abutting against the side of the battery away from the carrier substrate.

[0022] By providing a first connecting portion and a second connecting portion at the ends of the first positioning portion and the second positioning portion respectively, and connecting the first connecting portion and the second connecting portion to the bottom shell, the assembly of the support member and the bottom shell is realized. A predetermined height gap is formed between the side of the carrier substrate away from the projection assembly and the bottom of the inner cavity. Simultaneously, by connecting the first connecting portion and the second connecting portion to both ends of the fixing member, on the one hand, the design of the first connecting portion and the second connecting portion located at the ends of the first positioning portion and the second positioning portion away from the carrier substrate creates a height difference between the fixing member and the carrier substrate. This height difference creates a gap between the fixing member and the carrier substrate, allowing the fixing member to abut against the side of the battery away from the carrier substrate, and the fixing member and the carrier substrate together clamp and fix the battery. On the other hand, the first connecting portion and the second connecting portion can also be used to connect to the bottom shell and the fixing member, realizing the assembly of the support member and the bottom shell, as well as the assembly of the fixing member and the support member, thereby achieving structural reuse and simplifying the internal structure of the projection robot.

[0023] In some embodiments of this application, the bottom shell has two recesses, and the space formed by the recesses outside the bottom shell is used to accommodate the drive wheel;

[0024] The first connecting portion is connected to one of the recessed portions facing the top surface of the top shell, and the second connecting portion is connected to another of the recessed portions facing the top surface of the top shell.

[0025] By incorporating two recessed sections on the bottom shell corresponding to the two drive wheels, the drive wheels can be concealed within the space created by these recessed sections outside the bottom shell. This reduces the space occupied by the drive wheels outside the bottom shell, resulting in a smaller overall size for the projection robot. Furthermore, by connecting the first and second connecting sections to the top surface of the recessed sections facing the top shell, the extension lengths of the first and second positioning sections can be adapted to the recessed depth of the recessed sections within the bottom shell. The recessed sections serve as the connection points between the support members and the bottom shell.

[0026] In some embodiments of the present application, the support member comprises a third positioning portion extending from a third edge of the carrier substrate in a direction towards the projection assembly, the third edge being an edge of the carrier substrate adjacent to the first edge and the second edge, the third positioning portion abutting a side of the battery in the second horizontal direction;

[0027] The projection robot comprises a fixing member, the fixing member comprising:

[0028] a fixing plate, two ends of the fixing plate being connected to the first positioning portion and the second positioning portion respectively, the fixing plate abutting a side of the battery away from the carrier substrate;

[0029] a fourth positioning portion, the fourth positioning portion extending from an edge of the fixing plate away from the third positioning portion in the second horizontal direction towards the carrier substrate, the fourth positioning portion abutting a side of the battery away from the third positioning portion;

[0030] wherein the second horizontal direction is perpendicular to the first horizontal direction.

[0031] By connecting two ends of the fixing plate to the first positioning portion and the second positioning portion respectively, the assembly of the fixing member and the support member is achieved, and the battery is clamped and fixed by the fixing member and the carrier substrate together. Meanwhile, the fixing plate is provided with the fourth positioning portion, the fourth positioning portion extending from an edge of the fixing plate away from the third positioning portion in the second horizontal direction towards the support member, and the third positioning portion extending from a third edge of the carrier substrate in a direction towards the projection assembly, so that the third positioning portion and the fourth positioning portion abut two sides of the battery in the second horizontal direction respectively, and the third positioning portion and the fourth positioning portion can clamp and fix the battery together.

[0032] In some embodiments of the present application, the support member comprises:

[0033] a carrier substrate, a side of the carrier substrate towards the projection assembly being provided with the battery;

[0034] a third positioning portion, the third positioning portion extending from a third edge of the carrier substrate in a direction towards the projection assembly, the third positioning portion abutting a side of the battery in the second horizontal direction;

[0035] a pressing portion, the pressing portion extending from an end of the third positioning portion away from the carrier substrate in the second horizontal direction, so that a side of the pressing portion towards the carrier substrate abuts a side of the battery away from the carrier substrate;

[0036] The projection robot includes a fixing member, which is spaced apart on the side of the support substrate facing the projection assembly and spaced apart from the clamping part along the second horizontal direction. The fixing member abuts against the side of the battery away from the support substrate.

[0037] A third positioning part extends from the third edge of the support substrate in the direction toward the projection assembly. While positioning the battery by abutting against one side of the battery along the second horizontal direction, a clamping part is also provided at the end of the third positioning part away from the support substrate, creating a height difference between the clamping part and the support substrate. This height difference creates a gap between the clamping part and the support substrate, allowing the clamping part to abut against the side of the battery away from the support substrate. The clamping part and the support substrate together clamp and fix the battery. Furthermore, a fixing member is spaced apart on the side of the support substrate facing the projection assembly. The fixing member and the clamping part are spaced apart along the second horizontal direction and abut against the side of the battery away from the support member. Thus, the clamping part, the fixing member, and the support substrate together clamp the battery. The spaced arrangement of the fixing member and the clamping part along the second horizontal direction ensures a more balanced clamping force on the battery from the fixing member and the clamping part. The gap between the fixing member and the clamping part allows for heat dissipation of the battery, avoiding a situation where a large contact area with the battery during clamping results in poor heat dissipation.

[0038] In some embodiments of this application, the support member is provided with a second heat dissipation window, which is configured to correspond to the interval between the fixing member and the clamping part.

[0039] By incorporating a second heat dissipation window in the support unit, heat generated by the battery can be dissipated, preventing heat accumulation between the battery and the support unit. Furthermore, the spacing between the second heat dissipation window and the fixing and clamping parts corresponds to the battery's spacing, ensuring more uniform heat dissipation and preventing damage caused by localized overheating. On the other hand, the second heat dissipation window reduces the overall weight of the support unit, enabling a lightweight design for the bracket.

[0040] In some embodiments of this application, the first positioning part is provided with a first connecting part at the end away from the carrier substrate, the second positioning part is provided with a second connecting part at the end away from the carrier substrate, and the edge of the carrier substrate is provided with a third connecting part. The first connecting part and the second connecting part are both connected to the third connecting part at different positions of the bottom shell.

[0041] By providing the first connecting part, the second connecting part and the third connecting part to connect with the bottom shell, the assembly of the support and the bottom shell is realized, and since the bottom shell is hemispherical to cooperate with the top shell to make the shell spherical, the first connecting part, the second connecting part and the third connecting part are all formed with a height difference from the third connecting part, so that when the support is assembled with the bottom shell, the first connecting part, the second connecting part and the third connecting part can be connected to different positions of the bottom shell to adapt to the hemispherical shape of the bottom shell, and the bottom shell does not need to be additionally provided with a connecting structure to make the different connecting positions of the bottom shell and the support at the same height, so that the structure of the bottom shell can be simplified.

[0042] In some embodiments of the present application, the projection robot comprises a second circuit board, which is arranged on the side of the support away from the battery, and the second circuit board is electrically connected to the battery.

[0043] The second circuit board is electrically connected to the battery, so that the power supply of the battery can be controlled, and the battery can supply power to the projection robot. Moreover, the second circuit board is arranged on the side of the support away from the battery, and the second circuit board and the battery are spaced apart by the support, so that the heat generated by the operation of the two can not affect each other, and the heat can be dissipated.

[0044] In some embodiments of the present application, the support comprises:

[0045] A bearing substrate, one side of the bearing substrate facing the projection assembly is provided with the battery;

[0046] A plurality of protrusions, a plurality of the protrusions are protruded on the side of the bearing substrate away from the battery, and the second circuit board is arranged on the end of the plurality of the protrusions away from the bearing substrate.

[0047] The second circuit board is arranged on the end of the plurality of the protrusions away from the bearing substrate, and a spacing is formed between the second circuit board and the bearing substrate, so that the heat generated by the second circuit board can be dissipated.

[0048] Compared with the prior art, the present application has at least the following beneficial effects:

[0049] In the embodiments of the present application, the top shell is connected with the bottom shell to make the shell spherical, and the shell is formed with a first opening. Moreover, the inner shell located in the inner cavity is fixed with the projection assembly, and the inner shell can be pivoted with the projection assembly relative to the shell to make the projection assembly project through the projection hole of the inner shell to different directions outside the inner shell. Meanwhile, in the process of the pivoting of the inner shell with the projection assembly, the projection of the inner shell on the shell can cover the first opening, so that the dust and other foreign matters can not enter the inner cavity of the shell through the first opening, and the projection assembly can be shielded to avoid the user seeing the projection assembly from outside the shell through the first opening. Meanwhile, the battery is arranged in the bottom shell for the need of counterweight.

[0050] Furthermore, by setting a support member on the bottom shell and using the support member to house the battery, the battery can power the projection robot. A predetermined height gap is formed between the side of the support member away from the projection component and the bottom of the inner cavity. This gap provides space for the inner shell to pitch and rotate relative to the outer shell. That is, when the inner shell pitches and rotates relative to the outer shell, the inner shell at least partially passes through this gap. This ensures that the inner shell can pitch and rotate at a large angle while achieving mutual avoidance between the inner shell and the battery, thus preventing interference between the inner shell and the battery.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

Those of ordinary skill in the art can understand the specific meaning of these terms in the present application according to the specific situation.

[0074] In addition, the terms "mounting", "arrangement", "provided with", "connected", "linked" should be interpreted broadly. For example, it can be fixed connection, detachable connection, or integral structure; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication between two devices, elements or components.

Unless otherwise stated, the meaning of "multiple" is two or more.

[0076] Before explaining the technical solutions of the present application, the inventive concept of the present application is explained.

[0077] Figure 1 is a structural schematic diagram of a projection robot 1000 provided by an embodiment of the present application. Figure 2 is a structural schematic diagram of a projection robot 1000 (omitting part of the shell 11) provided by an embodiment of the present application.

[0078] With the humanization design of the projection robot 1000, on the basis of being able to automatically adjust the projection orientation direction of the projection assembly 20, the projection robot 1000 also increases the autonomous moving function. Specifically, the projection robot 1000 can be configured with a driving wheel 31, and the driving wheel 31 is used to enable the projection robot 1000 to autonomously move to different positions for projection. In order to cooperate with the operation of the driving wheel 31, the projection robot 1000 usually needs to be configured with different sensors, which are used to realize obstacle avoidance positioning, sound source positioning, etc. Of course, different sensors can also be used to realize other functions such as home appliance control and projection brightness adjustment.

[0079] However, since the projection assembly 20 of the existing projection robot 1000 usually relies on the rotation of the shell 11 to drive the rotation of the projection assembly 20 when adjusting the projection orientation direction of the projection assembly 20, the sensor mounted on the shell 11 also rotates. Therefore, when the projection orientation direction of the projection assembly 20 changes, the position of the spatial coordinate system of the sensor will also change, and the sensor cannot always keep its spatial coordinate system at the same position for detection, resulting in low detection accuracy of the sensor and affecting the use of the functions related to the sensor of the projection robot 1000.

[0080] Therefore, it is urgent to design a projection robot, which can keep the shell stationary while the projection assembly is tilted to adjust the projection direction of the projection assembly.

[0081] The projection robot of the present application adopts a double-layer shell structure, so that the projection assembly 20 is tilted relative to the inner shell with respect to the outer shell, thereby keeping the outer shell different. Moreover, while designing the double-layer shell structure, the interference problem between the inner shell and the device provided on the outer shell during relative rotation of the double-layer shell is further considered.

[0082] The technical solutions in some embodiments of the present application will be described clearly and completely below in combination with the drawings in some embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0083] In some embodiments, as shown in Figure 1 and Figure 2 , the projection robot 1000 comprises a shell 11.

[0084] The shell 11 can be spherical, square, irregular, etc., which is not specifically limited in the present embodiment.

[0085] The shell 11 provides installation space for the internal structure and circuit of the projection robot 1000 and protects them.

[0086] In some embodiments, the projection robot 1000 comprises a projection assembly 20, which is tiltable and provided on the shell 11.

[0087] By tilting the projection assembly 20 relative to the shell 11, the projection direction of the projection assembly 20 can be adjusted, so that the projection assembly 20 can project towards different directions such as the ground, the wall, the ceiling, etc.

[0088] In some embodiments, the projection robot 1000 comprises a drive wheel 31, which is provided at the bottom of the shell 11.

[0089] By providing the drive wheel 31 at the bottom of the shell 11, the drive wheel 31 can drive the projection robot 1000 to move to different positions, so that the projection assembly 20 can project in different places.

[0090] In some embodiments, as shown in Figure 3 and Figure 4 , the shell 11 comprises a bottom shell 111, the bottom of which is provided with the drive wheel 31, and the projection assembly 20 is tiltable and provided on the bottom shell 111.

[0091] The driving wheel 31 is arranged at the bottom of the bottom shell 111, and the driving wheel 31 can drive the bottom shell 111 to move, so that the projection robot 1000 moves to different positions. The projection assembly 20 can be tilted and rotated on the bottom shell 111. The overall center of the projection robot 1000 is relatively close to the bottom shell 111, that is, the center of gravity is relatively low, which can reduce the risk of the projection robot 1000 falling. The driving wheel 31 drives the projection robot 1000 to move relatively stably and reliably.

[0092] In some embodiments, the shell 11 includes a top shell 112 connected above the bottom shell 111, so that the shell 11 forms a spherical shape, and an inner cavity for accommodating the projection assembly 20 is formed between the top shell 112 and the bottom shell 111.

[0093] The top shell 112 is connected to the bottom shell 111 by covering, so that different internal structures and circuits of the projection robot 1000 can be respectively installed on the top shell 112 and the bottom shell 111, and then the two are connected by covering. The assembly and disassembly of the projection robot 1000 are relatively low in difficulty.

[0094] In some embodiments, the shell 11 is formed with a first opening 11a.

[0095] The top shell 112 and the bottom shell 111 are connected to make the shell 11 spherical, so that the extension direction of the first opening 11a is the same as the circumferential direction of the spherical shape. When the projection assembly 20 is tilted and rotated relative to the shell 11, the inner shell 12 can better cover the first opening 11a at all times, avoiding motion interference.

[0096] The first opening 11a is a window arranged on the shell 11. The window is used to communicate the space outside the shell 11 with the inner cavity, so that the projection assembly 20 located in the inner cavity can project to the space outside the shell 11 through the window.

[0097] In some embodiments, the shell 11 includes an inner shell 12 located in the inner cavity. The inner shell 12 is fixed to one end of the projection assembly 20 facing the first opening 11a, so that the inner shell 12 can be tilted and rotated with the projection assembly 20. During the tilting and rotating process, the projection of the inner shell 12 on the shell 11 covers the first opening 11a. The inner shell 12 is provided with a projection hole 12a for the projection assembly 20 to project to the outside of the inner shell 12.

[0098] The first opening 11a is formed in the outer shell 11, and the inner shell 12 located in the inner cavity is fixed with the projection assembly 20. The inner shell 12 can be tilted relative to the outer shell 11 to enable the projection assembly 20 to project light to the outside of the inner shell 12 through the projection hole 12a of the inner shell 12. In the process of tilting the inner shell 12 relative to the outer shell 11, the inner shell 12 can cover the first opening 11a on the outer shell 11, so that dust and other foreign matters cannot enter the inner cavity of the outer shell 11 through the first opening 11a, and the projection assembly 20 can be shielded from the user outside the outer shell 11 through the first opening 11a.

[0099] That is, when changing the projection direction of the projection assembly 20, the inner shell 12 forms a double-layer shell structure with the outer shell 11, and the inner shell 12 is tilted relative to the outer shell 11, while the outer shell 11 remains stationary.

[0100] As shown in FIGS. 1A and 1B, the inner shell 12 is tilted relative to the outer shell 11, and the projection hole 12a of the inner shell 12 is closer to the top of the top shell 112 than the projection hole 112a of the outer shell 112. Figure 3 and Figure 5 As shown in FIGS. 1A and 1B, the inner shell 12 is tilted relative to the outer shell 11, and the projection hole 12a of the inner shell 12 is closer to the top of the top shell 112 than the projection hole 112a of the outer shell 112. Figure 5 As shown in FIGS. 1A and 1B, the inner shell 12 is tilted relative to the outer shell 11, and the projection hole 12a of the inner shell 12 is closer to the top of the top shell 112 than the projection hole 112a of the outer shell 112. Figure 3 As shown in FIGS. 1A and 1B, the inner shell 12 is tilted relative to the outer shell 11, and the projection hole 12a of the inner shell 12 is closer to the top of the top shell 112 than the projection hole 112a of the outer shell 112. Figure 5 As shown in FIGS. 1A and 1B, the inner shell 12 is tilted relative to the outer shell 11, and the projection hole 12a of the inner shell 12 is closer to the top of the top shell 112 than the projection hole 112a of the outer shell 112. Figure 3 As shown in FIGS. 1A and 1B, the inner shell 12 is tilted relative to the outer shell 11, and the projection hole 12a of the inner shell 12 is closer to the top of the top shell 112 than the projection hole 112a of the outer shell 112.

[0101] In some embodiments, the projection robot 1000 includes a sensor.

[0102] As described above, when changing the projection direction of the projection assembly 20, the inner shell 12 forms a double-layer shell structure with the outer shell 11, and the inner shell 12 is tilted relative to the outer shell 11, while the outer shell 11 remains stationary. When the projection robot 1000 is expanded to have an autonomous moving function, the sensor can be installed to the outer shell 11, so that the position of the spatial coordinate system of the sensor remains unchanged, the sensor has higher detection accuracy, and the use of the functions related to the sensor of the projection robot 1000 is not affected.

[0103] In some embodiments, as shown in FIG. 1A, the projection robot 1000 includes a support 711 arranged on the bottom shell 111. Figures 6 to 8 By arranging the support 711 on the bottom shell 111, the support 711 can be used to provide mounting positions for the components of the projection robot 1000 arranged on the bottom shell 111.

[0104]

[0105] ​In some embodiments, the projection robot 1000 comprises a battery 72, the battery 72 is arranged on the support 711, and a space of a preset height is formed between the support 711 away from the projection assembly 20 and the bottom of the inner cavity. When the inner shell 12 is tilted relative to the outer shell 11, the inner shell 12 at least partially passes through the space between the battery 72 and the bottom shell 111.

[0106] By arranging the battery 72 on the support 711, a space of a preset height is formed between the support 711 away from the projection assembly 20 and the bottom of the inner cavity. When the inner shell 12 is tilted relative to the outer shell 11, the space can avoid the inner shell 12, so that the inner shell 12 at least partially passes through. In this way, the inner shell 12 and the battery 72 can be mutually avoided while ensuring that the inner shell 12 can be tilted at a large angle, and the inner shell 12 and the battery 72 are prevented from interfering with each other.

[0107] The battery 72 can supply power to the projection robot 1000. In addition, arranging the battery 72 in the bottom shell 111 can balance the weight of the projection robot 1000.

[0108] In some embodiments, as shown in Figures 7 to 9 The support 711 comprises a bearing substrate 711a, the bearing substrate 711a is suspended on the bottom shell 111, and the battery 72 is arranged on the side of the bearing substrate 711a facing the projection assembly 20.

[0109] By suspending the bearing substrate 711a on the bottom shell 111, a space can be formed between the bearing substrate 711a and the bottom of the inner cavity, and the bearing substrate 711a can be used to arrange the battery 72.

[0110] In some embodiments, the support 711 comprises a first positioning portion 711c, the first positioning portion 711c extends from a first edge of the bearing substrate 711a in a direction facing the projection assembly 20.

[0111] By arranging the first positioning portion 711c on the bearing substrate 711a, the first positioning portion 711c extends from the first edge of the bearing substrate 711a in a direction facing the projection assembly 20. The first positioning portion 711c can be used to abut a side of the battery 72 in the first horizontal direction, thereby positioning the battery 72 from the first horizontal direction.

[0112] In some embodiments, the support 711 comprises a second positioning portion 711d, the second positioning portion 711d extends from a second edge of the bearing substrate 711a in a direction facing the projection assembly 20, and the second edge is an edge of the bearing substrate 711a opposite the first edge in the first horizontal direction.

[0113] By disposing the second positioning portion 711d on the carrying substrate 711a, the second positioning portion 711d is disposed extending from the second edge of the carrying substrate 711a in a direction towards the projection assembly 20, and the second positioning portion 711d can be used to abut against one side of the battery 72 in the first horizontal direction, thereby positioning the battery 72 from the first horizontal direction.

[0114] In some embodiments, the first positioning portion 711c abuts against one side of the battery 72, and the second positioning portion 711d abuts against the side of the battery 72 away from the first positioning portion 711c.

[0115] By abutting the first positioning portion 711c and the second positioning portion 711d against two sides of the battery 72 while the carrying substrate 711a supports the battery 72, the first positioning portion 711c and the second positioning portion 711d can jointly clamp and fix the battery 72.

[0116] In some embodiments, the first positioning portion 711c is provided with a first connecting portion 713 away from the end of the carrying substrate 711a, the second positioning portion 711d is provided with a second connecting portion 714 away from the end of the carrying substrate 711a, and the first connecting portion 713 and the second connecting portion 714 are connected to the bottom shell 111, so as to form a space between the side of the carrying substrate 711a away from the projection assembly 20 and the bottom of the inner cavity.

[0117] By disposing the first connecting portion 713 and the second connecting portion 714 at the ends of the first positioning portion 711c and the second positioning portion 711d respectively, and connecting the first connecting portion 713 and the second connecting portion 714 to the bottom shell 111, the assembly of the support 711 and the bottom shell 111 is achieved, and a space of a preset height is formed between the side of the carrying substrate 711a away from the projection assembly 20 and the bottom of the inner cavity.

[0118] In some embodiments, the edge of the carrying substrate 711a is provided with a third connecting portion 715, and the first connecting portion 713 and the second connecting portion 714 form a height difference with the third connecting portion 715 to be connected to different positions of the bottom shell 111.

[0119] The support 711 is assembled with the bottom shell 111 by connecting the first connecting portion 713, the second connecting portion 714 and the third connecting portion 715 with the bottom shell 111. Since the bottom shell 111 is hemispherical to cooperate with the top shell 112 to make the outer shell 11 spherical, the first connecting portion 713, the second connecting portion 714 and the third connecting portion 715 are arranged at different heights, so that the first connecting portion 713, the second connecting portion 714 and the third connecting portion 715 can be connected to different positions of the bottom shell 111 to adapt to the hemispherical shape of the bottom shell 111 when the support 711 is assembled with the bottom shell 111. The bottom shell 111 does not need to be additionally provided with a connecting structure to make the different connecting positions of the bottom shell 111 and the support 711 at the same height, and the structure of the bottom shell can be simplified.

[0120] In some embodiments, the projection robot 1000 includes two drive wheels 31, and the bottom shell 111 is provided with two inner recesses 111b corresponding to the two drive wheels 31. Each inner recess 111b is formed in a space outside the bottom shell 111 to accommodate the drive wheel 31. The first connecting portion 713 is connected to the inner recess 111b facing the top surface of the top shell 112, and the second connecting portion 714 is connected to the inner recess 111b facing the top surface of the top shell 112.

[0121] The two inner recesses 111b are arranged on the bottom shell 111 corresponding to the two drive wheels 31, and the space formed outside the bottom shell 111 by the inner recess 111b is used to accommodate the drive wheel 31. The drive wheel 31 can be hidden, and the space occupied by the drive wheel 31 outside the bottom shell is reduced, and the overall volume of the projection robot 1000 is smaller. Furthermore, the first connecting portion 713 and the second connecting portion 714 are connected to the inner recess 111b facing the top surface of the top shell 112, and the extension length of the first positioning portion 711c and the second positioning portion 711d can be adapted to the inner recess depth of the inner recess 111b in the bottom shell 111. The inner recess 111b is used as the connecting position of the support 711 and the bottom shell 111.

[0122] In some embodiments, the support 711 includes a third positioning portion 711e. The third positioning portion 711e is arranged in a direction towards the projection assembly 20 from a third edge of the bearing substrate 711a. The third edge is an edge adjacent to the first edge and the second edge on the bearing substrate 711a. The third positioning portion 711e abuts one side of the battery 72 in the second horizontal direction.

[0123] The third positioning portion 711e abuts one side of the battery 72 in the second horizontal direction, so that the battery 72 can be positioned from the second horizontal direction.

[0124] In some embodiments, the second horizontal direction is perpendicular to the first horizontal direction.

[0125] The battery 72 can be positioned in the first horizontal direction and the second horizontal direction which is perpendicular to the first horizontal direction, and the position of the battery 72 in the horizontal direction can be fixed.

[0126] In some embodiments, the support 711 includes a fixing member 712 connected to the support 711, and the fixing member 712 abuts against a side of the battery 72 away from the support 711.

[0127] The fixing member 712 is connected to the support 711, and the fixing member 712 abuts against the side of the battery 72 away from the support 711, so that the fixing member 712 can press the battery 72 against the support 711 to clamp and fix the battery 72.

[0128] In some embodiments, the fixing member 712 includes a fixing plate 712a and a fourth positioning portion 712b. The two ends of the fixing plate 712a are respectively connected to the first positioning portion 711c and the second positioning portion 711d, and the fixing plate 712a abuts against the side of the battery 72 away from the support 711aa. The fourth positioning portion 712b is arranged in a direction close to the support 711aa from an edge of the fixing plate 712a away from the third positioning portion 711e in the second horizontal direction, and the fourth positioning portion 712b abuts against the side of the battery 72 away from the third positioning portion 711e.

[0129] The fourth positioning portion 712b abuts against the side of the battery 72 away from the third positioning portion 711e, and the fourth positioning portion 712b can clamp and fix the battery 72 together with the third positioning portion 711e in the second horizontal direction.

[0130] In some embodiments, the support 711 includes a pressing portion 711f arranged in the second horizontal direction from an end of the third positioning portion 711e away from the support 711a, so that the pressing portion 711f abuts against the side of the battery 72 away from the support 711a.

[0131] The pressing portion 711f abuts against the side of the battery 72 away from the support 711a, so that the pressing portion 711f can press the battery 72 against the support 711a to clamp and fix the battery 72. In addition, the battery 72 is also pressed against the support 711a by the fixing member 712. The fixing member 712 and the pressing portion 711f are arranged in the second horizontal direction, and the pressing force of the battery 72 by the fixing member 712 and the pressing portion 711f is balanced. The interval between the fixing member 712 and the pressing portion 711f can allow the battery 72 to dissipate heat, so that the battery 72 is not in contact with a large area at the same time, which can cause poor heat dissipation of the battery 72.

[0132] In some embodiments, the bearing substrate 711a is provided with a second heat dissipation window corresponding to the battery 72.

[0133] By providing the bearing substrate 711a with the second heat dissipation window, on the one hand, the heat generated by the battery 72 can be dissipated from the second heat dissipation window, avoiding the accumulation of heat between the battery 72 and the bearing substrate 711a. On the other hand, the second heat dissipation window can reduce the overall weight of the bearing substrate 711a, achieving a lightweight design of the support 711.

[0134] In some embodiments, the battery 72 includes a second circuit board 73, which is arranged on the support 711 and electrically connected to the battery 72.

[0135] By arranging the second circuit board 73 on the support 711 and electrically connecting the second circuit board 73 to the battery 72, the power supply of the battery 72 can be controlled.

[0136] In some embodiments, the second circuit board 73 is arranged on the side of the support 711 away from the battery 72.

[0137] By arranging the second circuit board 73 on the side of the support 711 away from the battery 72, the second circuit board 73 and the battery 72 are spaced apart by the support 711, which can avoid the situation that the heat generated by the two when working affects each other, and is conducive to heat dissipation.

[0138] In some embodiments, the support 711 includes a plurality of protruding portions 711g, which are arranged on the side of the bearing substrate 711a away from the battery 72, and the second circuit board 73 is arranged on the end of the plurality of protruding portions 711g away from the bearing substrate 711a.

[0139] By arranging the second circuit board 73 on the end of the plurality of protruding portions 711g away from the bearing substrate 711a, a distance is formed between the second circuit board 73 and the bearing substrate 711a, which facilitates the dissipation of heat generated by the second circuit board 73.
