Description

Technical Field

[0001] This invention relates to the field of cleaning robot technology, and in particular to a forward collision structure and a cleaning robot. Background Technology

[0002] With the popularization of smart homes, cleaning robots such as robot vacuums and robot mops are very popular among consumers because they have functions such as automatic cleaning, mopping, and monitoring. Taking robot vacuums as an example, in order to automatically complete the floor cleaning work, robot vacuums use their own sensors to perceive the surrounding environment, plan cleaning strategies according to different external environments, and try to avoid obstacles during movement and cleaning, reducing collisions with household appliances and other obstacles.

[0003] When performing automatic cleaning tasks, if the robot vacuum cleaner's battery is low, it will automatically return to its charging dock to recharge. However, when the robot vacuum cleaner is searching for the charging dock, it is often affected by reflected signals from different locations, which can cause interference and prevent it from successfully aligning with the charging dock, resulting in charging failure. Summary of the Invention

[0004] The main objective of this invention is to provide a forward-collision structure and a cleaning robot, aiming to improve the problem of charging failure in cleaning robots in related technologies.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this invention is to provide a forward collision structure, including a forward collision structure body, a separation component, a first receiving sensor, and a second receiving sensor. The separation component is installed on the forward collision structure body and has a cavity. The separation component includes a partition plate disposed in the cavity, dividing the cavity into a first cavity and a second cavity. The first receiving sensor is housed in the first cavity and is used to receive a first signal. The second receiving sensor is housed in the second cavity and is used to receive a second signal. The second signal is different from the first signal. The partition plate is used to prevent the first signal from being reflected into the second cavity and to prevent the second signal from being reflected into the first cavity.

[0006] In some optional embodiments, the frontal impact structure body has a first mounting space, a first opening, and a second opening, both of which communicate with the first mounting space. The partition component is mounted in the first mounting space, with the first cavity communicating with the first opening and the second cavity communicating with the second opening. The frontal impact structure body includes a baffle plate located between the first opening and the second opening, the baffle plate abutting against the surface of the baffle plate near the first mounting space.

[0007] In some alternative embodiments, the surface of the shield near the first mounting space is provided with a slot, and one end of the partition near the shield is inserted into the slot.

[0008] In some optional embodiments, the frontal impact structure body further includes a second mounting space, which communicates with the first mounting space. The frontal impact structure also includes a circuit board, which is fixed to the second mounting space. The connector is connected to the circuit board, and both the first and second receiving sensors are electrically connected to the circuit board.

[0009] In some optional embodiments, the circuit board includes a first surface and a second surface disposed opposite to each other, and the circuit board has a through hole that penetrates through the first surface and the second surface. The connector includes a connector body and a buckle, the buckle being connected to the connector body, the buckle passing through the through hole and abutting against the first surface and a third surface respectively, the third surface being the surface between the first surface and the second surface. The cavity is disposed in the connector body, and the first opening, the second opening, the first cavity, and the second cavity are all in communication with the through hole.

[0010] In some alternative embodiments, the circuit board is provided with an abutment portion that is connected to the third surface, and the connector body abuts against the abutment portion.

[0011] In some optional embodiments, the frontal impact structure body includes a frontal impact plate and a mounting plate. The mounting plate is connected to both the frontal impact plate and the circuit board, and the mounting plate and the frontal impact plate form a first mounting space and a second mounting space, respectively. The first opening, the second opening, and the shielding plate are all disposed on the frontal impact plate.

[0012] In some alternative embodiments, the connector has a third opening on its sidewall away from the circuit board, the third opening communicating with the first cavity, and the first receiving sensor is disposed at the third opening.

[0013] In some alternative embodiments, the connector is further provided with a fourth opening on the sidewall away from the circuit board, the fourth opening communicating with the second cavity, and the second receiving sensor is disposed at the fourth opening.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in the embodiments of the present invention is to provide a cleaning robot, including the aforementioned front collision structure.

[0015] The beneficial effects of the embodiments of the present invention are as follows: Unlike existing technologies, the front-collision structure and cleaning robot provided in this invention, by setting a partition, eliminate the processing time of the second signal reflected into the first cavity, allowing the robot to process only the first signal entering the second cavity. Similarly, by eliminating the processing time of the first signal reflected into the second cavity, the robot can process only the second signal entering the first cavity. This arrangement reduces the likelihood of the robot failing to align smoothly with the charging dock due to reflected signals from different locations, thereby improving the alignment efficiency between the robot's power terminals and the charging dock's charging terminals.

[0025] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" or "attached to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] The forward collision structure described in this embodiment of the invention is applicable to cleaning robots with this structure, such as robotic vacuum cleaners, robotic mops, and robotic vacuum and mop combos. The forward collision structure enables the cleaning robot to receive a recharging signal emitted by a charging dock, which is compatible with the cleaning robot. It is understood that the forward collision structure described in this embodiment of the invention is not limited to the cleaning robots mentioned above, but can also be applied to all intelligent robots that utilize this forward collision structure, enabling the intelligent robot to automatically recharge when the forward collision structure receives the recharging signal. For simplicity, the following embodiments use robotic vacuum cleaners as examples. For instance, Figure 1 The diagram shows a structural block diagram of a robotic vacuum cleaner. The front collision structure is installed on the robotic vacuum cleaner and is electrically connected to the main control unit of the robotic vacuum cleaner to receive the recharge signal from the charging dock.

[0029] To help readers understand the recharging principle of the embodiments of the present invention, the automatic recharging function of the cleaning robot is explained below.

[0030] When the robot vacuum detects that its remaining battery capacity is lower than a reference value, it will move along a preset route based on an image algorithm to receive signals from the transmitting sensor on the charging dock. During this movement, when the robot vacuum's receiving sensor receives an infrared signal from the transmitting sensor on the charging dock, it transmits the received signal to the robot vacuum's main control unit.

[0031] Then, the robot vacuum's main control unit moves to the charging dock based on the received signal and generates a start signal via a receiving sensor, which is then transmitted to a transmitting sensor. The charging dock's transmitting sensor detects this start signal and transmits a connection request signal to the robot vacuum's receiving sensor.

[0032] Subsequently, when the main control unit detects a connection request signal via the receiving sensor, it electrically connects the power terminal of the robot vacuum cleaner to the charging terminal of the charging dock according to the control signal of the main control unit. When the power terminal and the charging terminal are connected to each other, the main control unit transmits the connection signal to the transmitting sensor of the charging dock through the receiving sensor of the robot vacuum cleaner. Then, the charging dock receives the connection signal through the transmitting sensor and generates a charging signal to charge the battery of the robot vacuum cleaner.

[0033] Subsequently, when the battery is fully charged, the main control unit sends a completion signal to the transmitter sensor on the charging dock, and upon receiving the completion signal, the charging component cuts off the charging signal. After the charging signal is cut off, no further connection signal is generated to link with the cleaning robot.

[0034] Meanwhile, during the charging process of the robot vacuum cleaner, if the robot vacuum cleaner generates an end signal or if the charging dock generates a fault signal, the connection request signal is cut off and the charging operation terminates after a certain time interval.

[0035] Please see Figure 2 and Figure 3 The example shown, Figure 2 This is an exploded view of the forward collision structure provided in one embodiment of the present invention. Figure 3 for Figure 2The diagram shows a cross-sectional view of a forward-impact structure. This forward-impact structure includes a front-impact structure body 10, a partition assembly 20, a first receiving sensor 30, and a second receiving sensor 40. The partition assembly 20 is mounted on the front-impact structure body 10 and has a cavity (not shown). The partition assembly 20 includes a partition 22 disposed within the cavity, dividing the cavity into a first cavity 21a and a second cavity 21b. The first receiving sensor 30 is housed in the first cavity 21a and is used to receive a first signal. The second receiving sensor 40 is housed in the second cavity 21b and is used to receive a second signal. The partition is used to prevent the first signal from being reflected into the second cavity 21b and to prevent the second signal from being reflected into the first cavity 21a. The first signal and the second signal are different; that is, the first receiving sensor 30 only receives the first signal and then generates a corresponding action signal output, and the second receiving sensor 40 only receives the second signal and then generates a corresponding action signal output. By setting up the partition 22, the processing time for the second signal reflected into the first cavity 21a is eliminated, allowing the robot vacuum to process only the first signal entering the second cavity 21b. Similarly, the processing time for the first signal reflected into the second cavity 21b is eliminated, allowing the robot vacuum to process only the second signal entering the first cavity 21a. This design reduces the likelihood of the robot vacuum failing to align properly with the charging dock due to reflected signals from different locations, thereby improving the alignment efficiency between the robot vacuum's power terminals and the charging dock's charging terminals.

[0036] It should be noted that the positions of the first cavity 21a and the second cavity 21b in this embodiment of the invention are relative to the front collision structure assembled on the cleaning robot. Specifically, the first cavity 21a is located on one side along a direction perpendicular to the central axis of the cleaning robot, and the second cavity 21b is located on the other side along the same direction. If both the first cavity 21a and the second cavity 21b are coaxially arranged with respect to the direction perpendicular to the central axis of the cleaning robot, the robot's posture cannot be adjusted according to the relative positions of the first receiving sensor 30 and the second receiving sensor 40, thus preventing the alignment charging function from being achieved.

[0037] For ease of explanation, the following is in conjunction with the appendix. Figures 2 to 8 The specific structures of the aforementioned frontal collision structure body 10, separation component 20, first receiving sensor 30, and second receiving sensor 40 will be described in turn. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] For the aforementioned frontal collision structure body 10, please refer to [link / reference needed]. Figure 2 and Figure 3In the example shown, the front impact structure body 10 serves not only as a mounting support structure for the partition component 20 but also as a protective structure for the robotic vacuum cleaner. When the robotic vacuum cleaner is subjected to an external impact, the front impact structure body 10 can absorb the impact force, providing protection for the robotic vacuum cleaner and the partition component 20 mounted on the front impact structure body 10. Specifically, the front impact structure body 10 includes a front impact plate 11 and a mounting plate 12, which are connected. A first mounting space 10a is formed between the front impact plate 11 and the mounting plate 12, and the first mounting space 10a is used to accommodate the partition component 20. Optionally, the front impact plate 11 and the mounting plate 12 are detachably connected. The embodiments of the present invention do not specifically limit the method of detachable connection; the front impact plate 11 and the mounting plate 12 can be connected by bolts, snap-fit ​​connections, or hinges. Exemplarily, the front impact plate 11 and the mounting plate 12 are connected by bolts. Since the front impact plate 11 and the mounting plate 12 are detachably connected, the front impact structure body 10 can be easily disassembled and assembled, facilitating the replacement of the partition component 20 and thus improving the assemblability of the front impact structure. It is understood that the front impact plate 11 and the mounting plate 12 can also be integrally connected or bonded, as long as the requirement for accommodating the partition component 20 is met. Next, the specific structure of the aforementioned front impact plate 11 and mounting plate 12 will be described.

[0039] For the aforementioned front impact plate 11, please refer to [link / reference needed]. Figure 1 In the example shown, the front impact plate 11 is generally a plate-like structure with both ends bent. Specifically, the front impact plate 11 includes a first sidewall 111, a second sidewall 112, and a third sidewall 113. The first sidewall 111 is connected to one end of the second sidewall 112, and the third sidewall 113 is connected to the other end of the second sidewall 112. The first sidewall 111, the second sidewall 112, and the third sidewall 113 together form a U-shaped structure. The first sidewall 111 is used to connect to one side of the sweeping robot along its central axis, and the third sidewall 113 is used to connect to the other side of the sweeping robot along its central axis, so as to realize the connection and fixation between the front impact plate 11 and the sweeping robot. The second sidewall 112 is used to connect to the mounting plate 12, so that the mounting plate 12 is fixed to the front impact plate 11. The second sidewall 112 has a through opening 11a and a second opening 11b, both of which are used to communicate the first mounting space 10a and the external environment of the front impact structure body 10.

[0040] The first opening 11a and the second opening 11b are independent openings. Specifically, the first sidewall 111 has a through opening, and the front impact structure body 10 also includes a baffle plate 13 connected to the first sidewall 111, dividing the opening into the first opening 11a and the second opening 11b, i.e., the first opening 11a and the second opening 11b are located at opposite ends of the baffle plate 13. It is understood that whether the first opening 11a and the second opening 11b are connected can be adaptively adjusted according to actual usage requirements. For example, in some other embodiments of the present invention, the first opening 11a and the second opening 11b may also be connected openings, i.e., the first sidewall 111 has the aforementioned opening, the first opening 11a is a part of the opening, and the second opening 11b is the remaining part of the opening.

[0041] For the aforementioned mounting plate 12, please continue to combine Figure 7 See also Figure 3 The mounting plate 12 is generally rectangular in shape. Specifically, the mounting plate 12 is connected to the first sidewall 111 of the front impact plate 11. The mounting plate 12 has a first receiving groove 121, and the first sidewall 111 covers the opening of the first receiving groove 121 to form the aforementioned first mounting space 10a. Both the first opening 11a and the second opening 11b communicate with the first mounting space 10a. Optionally, the receiving groove of the mounting plate 12 is formed by a partial recess on the surface of the mounting plate 12 near the front impact plate 11 in the direction away from the front impact plate 11.

[0042] For the aforementioned separator component 20, please refer to... Figure 8 See also Figures 3 to 6 The separating component 20 serves not only as a mounting support structure for the first receiving sensor 30 and the second receiving sensor 40, but also as a signal filtering structure for the two sensors. Specifically, the separating component 20 includes a connector 21 and a partition 22. The connector 21 is installed in the first mounting space 10a and has a cavity (not shown). The partition 22 is connected to the connector 21 and divides the cavity into a first cavity 21a and a second cavity 21b. The first cavity 21a communicates with a first opening 11a, and the second cavity 21b communicates with a second opening 11b. The first cavity 21a is used to accommodate the first receiving sensor 30, and the second cavity 21b is used to accommodate the second receiving sensor 40. It is understood that the embodiments of the present invention do not specifically limit how the partition 22 is connected to the connector 21. The partition 22 and the connector 21 can be connected by adhesive, integral connection or plug-in connection, as long as the partition 22 can block the second signal reflected from the surface of the first cavity 21a to the second receiving sensor 40 and can block the first signal reflected from the surface of the second cavity 21b to the first receiving sensor 30. For example, the partition 22 and the connector 21 are integrally connected.

[0043] Since the partition 22 is integrally connected to the connector 21, but not integrally connected to the shield 13, there will be a gap between the partition 22 and the shield 13. This gap allows the first signal and the second signal to pass through. The first signal can be reflected from the inner surface of the second cavity 21b to the inner surface of the shield 13, and then reflected from the inner surface of the shield 13 to the first receiving sensor 30. The second signal can be reflected from the inner surface of the first cavity 21a to the inner surface of the shield 13, and then reflected from the inner surface of the shield 13 to the second receiving sensor 40. To reduce the interference of this gap on the first receiving sensor 30 and the second receiving sensor 40, specifically, the surfaces of the partition 22 and the shield 13 near the first mounting space 10a are connected. For example, the surface of the shield 13 near the first mounting space 10a is provided with a slot 131, and the portion of the partition 22 extending out of the connector 21 near the shield 13 is inserted into the slot 131. With this configuration, the gap between the partition 22 and the shield 13 can be filled by the portion of the partition 22 extending beyond the connector 21 near the shield 13. Therefore, neither the first nor the second signal can propagate through this gap, thereby reducing the interference of this gap on the first receiving sensor 30 and the second receiving sensor 40. It is understood that the partition 22 and the shield 13 can also be bonded together, which can at least partially achieve the above effect. It is also understood that if the first opening 11a and the second opening 11b are connected openings, the partition 22 can also extend beyond the connector 21. The portion of the partition 22 extending beyond the connector 21 must also be able to block the second signal reflected from the surface of the first cavity 21a to the second receiving sensor 40 and the first signal reflected from the surface of the second cavity 21b to the first receiving sensor 30.

[0044] To increase the effective signal reception range of the first receiving sensor 30 and the second receiving sensor 40, please refer to [link / reference]. Figure 6 In the example shown, the side wall of the first cavity 21a away from the partition 22 is set at an acute angle to the partition 22, and the side wall of the second cavity 21b away from the partition 22 is set at an acute angle to the partition 22.

[0045] The first receiving sensor 30 and the second receiving sensor 40 generate heat during operation. To reduce heat buildup and maintain the normal operating temperature of the first receiving sensor 30 and the second receiving sensor 40, please refer to... Figure 6 See also Figure 4In the illustrated example, the connector 21 further includes a third opening 211a on its sidewall away from the first opening 11a. This third opening 211a communicates with the first cavity 21a, and the first receiving sensor 30 is located at the third opening 211a. Furthermore, the connector 21 also includes a fourth opening 211b on its sidewall away from the second opening 11b. This fourth opening 211b communicates with the second cavity 21b, and the second receiving sensor 40 is located at the fourth opening 211b. To dissipate the heat accumulated in the first mounting space 10a to the external environment, the bottom of the first receiving groove 121 of the mounting plate 12 can be perforated, allowing the heat generated by the first receiving sensor 30 and the second receiving sensor 40 during operation to be directly exchanged with the external environment of the front-mounted bracket structure through the third opening 211a and the fourth opening 211b.

[0046] For the first receiving sensor 30 and the second receiving sensor 40 mentioned above, please refer to... Figure 5 and Figure 6 In the illustrated example, a first receiving sensor 30 is housed in a first cavity 21a, with its receiving end facing a first opening 11a. The electrical connection terminal of the first receiving sensor 30 can be electrically connected to the main control unit of the robotic vacuum cleaner. A second receiving sensor 40 is housed in a second cavity 21b, with its receiving end facing a second opening 11b. The electrical connection terminal of the second receiving sensor 40 can also be electrically connected to the main control unit of the robotic vacuum cleaner. Exemplarily, both the first receiving sensor 30 and the second receiving sensor 40 are infrared receiving chips that only receive signals transmitted to the robotic vacuum cleaner from the external environment and cannot transmit signals back to the external environment.

[0047] In this embodiment of the invention, when the robot vacuum returns to the charging dock, on the one hand, the robot vacuum can adjust its own posture according to the first receiving sensor 30 and the second receiving sensor 40 set at the interval of the front collision structure, so that while the first receiving sensor 30 receives the first signal from the first transmitting sensor of the charging dock, the second receiving sensor 40 can also receive the second signal from the second transmitting sensor of the charging dock, thereby improving the alignment efficiency between the power terminal of the robot vacuum and the charging terminal of the charging dock.

[0048] On the other hand, the partition 22 blocks the first signal that enters the second cavity 21b through the second opening 11b and is then reflected back to the first cavity 21a through the inner surface of the second cavity 21b. This eliminates the processing time of the robot vacuum's main control unit for the first signal entering through the second opening 11b, allowing the robot vacuum's main control unit to receive only the signal input through the first opening 11a. Similarly, the partition 22 also eliminates the processing time of the second signal entering through the first opening 11a, allowing the robot vacuum's main control unit to receive only the signal input through the second opening 11b. This improves the alignment efficiency between the robot vacuum's power terminal and the charging terminal of the charging dock.

[0049] It should be noted that the embodiments of the present invention do not limit how the first receiving sensor 30 and the second receiving sensor 40 are electrically connected to the main control unit of the sweeping robot. Please refer to the following for further details regarding the embodiments of the present invention. Figure 5 In the example shown, the front-collision structure also includes a circuit board 50, which is fixedly connected to the front-collision structure body 10. The electrical connection terminals of the first receiving sensor 30 and the second receiving sensor 40 are both electrically connected to the main control unit of the robot vacuum cleaner through the circuit board 50. It is understood that the circuit board 50 can be adaptively adjusted according to actual usage requirements. For example, in some other embodiments of the present invention, the circuit board 50 may not be provided, meaning that the electrical connection terminals of the first receiving sensor 30 and the second receiving sensor 40 can both extend through the mounting plate 12 to the outside of the mounting plate 12 for electrical connection to the main control unit of the robot vacuum cleaner.

[0050] To address the issue that the mounting positions of the receiving ends of the first receiving sensor 30 and the second receiving sensor 40 are easily altered by external impacts, please refer to [link / reference needed]. Figure 6 In the illustrated example, optionally, the third opening 211a of the connector 21 also has a first positioning groove 211c, and the first receiving sensor 30 has a first positioning protrusion 31 that matches the first positioning groove 211c. When the first receiving sensor 30 is installed in the third opening 211a, the first positioning protrusion 31 is inserted into the first positioning groove 211c. Further, the side wall of the first positioning groove 211c near the mounting plate 12 has a notch for the first positioning protrusion 31 to be inserted. Similarly, the fourth opening 211b of the connector 21 also has a second positioning groove 211d, and the second receiving sensor 40 has a second positioning protrusion 41 that matches the second positioning groove 211d. When the second receiving sensor 40 is installed in the fourth opening 211b, the second positioning protrusion 41 is inserted into the second positioning groove 211d. Further, the side wall of the second positioning groove 211d near the mounting plate 12 also has a notch for the second positioning protrusion 41 to be inserted.

[0051] To improve the structural compactness of the forward collision structure and reduce its installation space requirements, optionally, please refer to [further details]. Figure 4 In the example shown, the front impact structure body 10 also has a second mounting space 10b, which is connected to the first mounting space 10a, the first opening 11a, and the second opening 11b, respectively. The circuit board 50 is housed in the second mounting space 10b. Specifically, the mounting plate 12 is connected to the first sidewall 111 of the front impact plate 11. The mounting plate 12 also has a second receiving groove 122, one opening of which is connected to the first receiving groove 121. The first sidewall 111 of the front impact plate 11 covers the other opening of the second receiving groove 122 to form the aforementioned second mounting space 10b.

[0052] Please continue reading for more details. Figure 3 In the example shown, the circuit board 50 includes a first surface 501 and a second surface 502 disposed opposite to each other. The circuit board 50 has a through hole 50a that penetrates the first surface 501 and the second surface 502. The first opening 11a, the second opening 11b, the first cavity 21a, and the second cavity 21b are all connected to the through hole 50a. The first surface 501 is the surface of the circuit board 50 near the first sidewall 111 of the front impact plate 11, and the second surface 502 is the surface of the circuit board 50 near the mounting plate 12. This arrangement allows the circuit board 50 to be housed within the front impact structure body 10 for protection. Furthermore, the through hole 50a on the circuit board 50 prevents interference from the circuit board 50 with signals incident through the first opening 11a and the second opening 11b.

[0053] To improve the assemblability of barrier components, please refer to [link / reference needed]. Figure 4In the illustrated example, the connector 21 further includes a connector body 211 and a latch 212. The latch 212 is connected to the connector body 211, passes through the through hole 50a, and abuts against the first surface 501 and the third surface 503 of the circuit board 50, respectively. The third surface 503 is the surface of the circuit board 50 located between the first surface 501 and the second surface 502. Specifically, there are two latches 212: one latch 212 is connected to the side wall of the first cavity 21a away from the partition 22, and the other latch 212 is connected to the side wall of the second cavity 21b away from the partition 22. With this configuration, when the barrier assembly is assembled in the first mounting space 10a, along the mounting direction perpendicular to the connector body 211, the two latches 212 exert two opposing forces to abut against the circuit board 50, thereby providing a better limiting effect for the connector body 211. It is understood that the number of latches 212 is not limited to this and can be adjusted adaptively according to actual usage requirements. Furthermore, the third surface 503 of the circuit board 50 is provided with an abutment portion 511. When the latch 212 abuts against the circuit board 50, the connector body 211 can abut against the abutment portion 511. With this configuration, the abutment portion 511 and the latch 212 respectively limit the connector body 211 along the installation direction of the connector body 211, further ensuring the fixing effect between the connector body 211 and the circuit board 50.
