[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of the present invention.

[0047] First, the professional terms that may be used in the embodiments of the present invention are explained:

[0048] AGV (Automated Guided Vehicle): An unmanned automated vehicle that has automatic guidance equipment such as magnetic strips, tracks, or lasers, travels along a planned path, is powered by batteries, and is equipped with safety protection and various auxiliary mechanisms (such as transfer and assembly mechanisms).

[0049] PCB (Printed Circuit Board): refers to a printed circuit board with point-to-point connections and printed components formed according to a predetermined design on a general substrate. It is the support body of electronic components and the carrier for the electrical connection of electronic components.

[0050] Multiple-output metal binding posts distribute a single input signal to multiple outputs, each capable of connecting to a different circuit. Metal binding posts typically utilize pin-type connections, with the number and placement of pins adjustable to meet specific needs. Once an input signal reaches the input of a metal binding post, it can be connected to different outputs via the pins, achieving signal distribution.

[0051] OT terminals are round, cold-pressed terminals with a round head and a cylindrical tail, hence the name. OT terminals are widely used for cable connections and are suitable for wiring and signal transmission in various electrical devices. To secure wires to an OT terminal, you typically need to use appropriate tools, such as a screwdriver or crimping pliers. The specific steps are as follows: 1. Strip the insulation from the cable harness to expose a certain length of wire. 2. Insert the wire into the cylindrical hole of the OT terminal, ensuring good contact between the wire and the metal portion of the OT terminal. 3. Use a tool to press the metal portion of the OT terminal tightly to secure the wire securely to the terminal.

[0052] Current AGV (Automated Guided Vehicle) designs contain numerous high-power components, such as power boards, motor drivers, and battery charging ports. These components all require battery power, meaning each component must be connected to the battery via a power harness. This results in numerous and complex power harnesses within the AGV, which takes up a lot of space.

[0053] In order to reduce the use of power harnesses, related technologies use a method of generating multiple branches on the power harness to supply power to various components, such as Figure 1However, due to the large number of electrical components, a power harness may have many branches. The riveting points of each branch will take up a certain amount of space. In addition, due to the high current, the power harness usually requires a thicker wire core to meet the flow rate requirements. This makes the multi-branch power harness very bloated and still takes up a lot of space inside the AGV, which is not conducive to production and assembly. On the other hand, if any branch fails and needs to be replaced, the entire power harness needs to be replaced, resulting in high disassembly and maintenance costs.

[0054] In order to improve the above problems, the relevant technology will also distribute power to each component through a one-to-many metal terminal (a one-to-many metal terminal includes an input end and multiple output ends, the input end is connected to the battery through a power harness, and the multiple output ends are connected to the corresponding components through a power harness). However, due to the heavy weight of the one-to-many metal terminal, the overall weight of the AGV automatic guided vehicle may be heavier, which will have an adverse impact on the operation and transportation of the AGV automatic guided vehicle.

[0055] In order to improve at least one of the above problems, an embodiment of the present invention provides a power distribution assembly and a mobile robot.

[0056] The power distribution assembly provided by the embodiment of the present invention is described in detail below. Figure 2 , which is a schematic diagram of a first structure of a power distribution assembly 1 provided in an embodiment of the present utility model, including:

[0057] a printed circuit board 11 and a plurality of male terminals 12;

[0058] Each of the male terminals 12 is soldered to the printed circuit board 11 , and each of the male terminals 12 is electrically connected to each other through internal circuits of the printed circuit board 11 ;

[0059] The male terminal 12 is used to connect to the female terminal 21, at least one female terminal 21 is electrically connected to the power supply 22 of the mobile robot 2, and at least two female terminals 21 are electrically connected to their respective corresponding motor drivers. Figure 6 .

[0060] The printed circuit board 11 is a PCB board, and multiple male terminals 12 are welded on the printed circuit board 11. The number of male terminals 12 is not less than 3. The specific number of male terminals 12 can be reasonably set according to the number and layout of electrical components in the mobile robot 2.

[0061] In one example, four male terminals 12 may be soldered to the printed circuit board 11, and the male terminals 12 are electrically connected to each other via internal circuitry within the printed circuit board 11. The internal circuitry may be ring-shaped, i.e., the first male terminal 12 is electrically connected to the second male terminal 12, the second male terminal 12 is electrically connected to the third male terminal 12, the third male terminal 12 is electrically connected to the fourth male terminal 12, and the fourth male terminal 12 is electrically connected to the first male terminal 12. The internal circuitry may also be semi-ring-shaped, e.g., the first male terminal 12 is electrically connected to the second male terminal 12, the second male terminal 12 is electrically connected to the third male terminal 12, the third male terminal 12 is electrically connected to the fourth male terminal 12, and so on.

[0062] It is understandable that Figure 2 The internal circuit is shown in a ring shape.

[0063] For each male terminal 12 of the power distribution component 1, the male terminal 12 can be used as a power input terminal or a power output terminal. One of the male terminals 12 of the power distribution component 1 can be used as a power input terminal, and the remaining male terminals 12 can be used as power output terminals to realize the power distribution function.

[0064] In an example, when the power distribution component 1 is applied to an AGV, one of the male terminals 12 (which can be the first male terminal 12) of the power distribution component 1 can be used as a power input terminal, and can be detachably electrically connected to a female terminal connected to a power harness. The other end of the power harness is electrically connected to a power source (battery), and the remaining male terminals 12 of the power distribution component 1 can be used as power output terminals (when the power signal is transmitted to the first male terminal 12, since the male terminals 12 are interconnected through internal lines, the power signal can be transmitted from the first male terminal 12 to the remaining male terminals 12, and the remaining male terminals 12 can all output power signals). They are electrically connected to the motor drivers, charging interfaces, etc. of the AGV through the female terminals and the power harness, and power is supplied to the motor drivers, charging interfaces, etc., to realize the power distribution function.

[0065] In the embodiment of the present utility model, the power distribution function is realized by the male terminals 12 in the power distribution component 1, which can improve the power supply method in which each electrical component needs to be connected to the battery through the power harness, and can reduce the use of the power harness inside the AGV to reduce the occupied space; compared with the method of generating multiple branches on the power harness, faults can be maintained separately, reducing the disassembly and maintenance costs; and the power distribution component 1 is lighter than a single-phase multi-metal terminal, which is convenient for the operation and transportation of the AGV.

[0066] In one possible implementation, see Figure 3 , the plurality of male terminals include a first male terminal 12 , a second male terminal 12 , a third male terminal 12 and a fourth male terminal 12 ;

[0067] The positive socket of the first male terminal 12 is electrically connected to the positive socket of the second male terminal 12, and the negative socket of the first male terminal 12 is electrically connected to the negative socket of the second male terminal 12;

[0068] The positive socket of the second male terminal 12 is electrically connected to the positive socket of the third male terminal 12, and the negative socket of the second male terminal 12 is electrically connected to the negative socket of the third male terminal 12;

[0069] The positive electrode socket of the third male terminal 12 is electrically connected to the positive electrode socket of the fourth male terminal 12, and the negative electrode socket of the third male terminal 12 is electrically connected to the negative electrode socket of the fourth male terminal 12;

[0070] The positive electrode socket of the fourth male terminal 12 is electrically connected to the positive electrode socket of the first male terminal 12 , and the negative electrode socket of the fourth male terminal 12 is electrically connected to the negative electrode socket of the first male terminal 12 .

[0071] It can be understood that, since the power signal includes a positive signal and a negative signal, each male terminal includes a positive jack and a negative jack.

[0072] In the embodiment of the present invention, the first male terminal 12 , the second male terminal 12 , the third male terminal 12 and the fourth male terminal 12 are interconnected via a ring circuit inside the printed circuit board 11 .

[0073] In one possible implementation, see Figure 4 , the plurality of male terminals include a first male terminal 12 , a second male terminal 12 , a third male terminal 12 and a fourth male terminal 12 ;

[0074] The positive socket of the first male terminal 12 is electrically connected to the positive socket of the fourth male terminal 12, and the negative socket of the first male terminal 12 is electrically connected to the negative socket of the fourth male terminal 12;

[0075] The positive electrode socket of the fourth male terminal 12 is electrically connected to the positive electrode socket of the third male terminal 12, and the negative electrode socket of the fourth male terminal 12 is electrically connected to the negative electrode socket of the third male terminal 12;

[0076] The positive electrode socket of the third male terminal 12 is electrically connected to the positive electrode socket of the second male terminal 12 , and the negative electrode socket of the third male terminal 12 is electrically connected to the negative electrode socket of the second male terminal 12 .

[0077] In the embodiment of the present invention, the first male terminal 12 , the second male terminal 12 , the third male terminal 12 and the fourth male terminal 12 are interconnected via a first semi-annular circuit inside the printed circuit board 11 .

[0078] In one possible implementation, see Figure 5 , the plurality of male terminals include a first male terminal 12 , a second male terminal 12 , a third male terminal 12 and a fourth male terminal 12 ;

[0079] The positive socket of the first male terminal 12 is electrically connected to the positive socket of the second male terminal 12, and the negative socket of the first male terminal 12 is electrically connected to the negative socket of the second male terminal 12;

[0080] The positive socket of the second male terminal 12 is electrically connected to the positive socket of the third male terminal 12, and the negative socket of the second male terminal 12 is electrically connected to the negative socket of the third male terminal 12;

[0081] The positive electrode socket of the third male terminal 12 is electrically connected to the positive electrode socket of the fourth male terminal 12 , and the negative electrode socket of the third male terminal 12 is electrically connected to the negative electrode socket of the fourth male terminal 12 .

[0082] In the embodiment of the present invention, the first male terminal 12 , the second male terminal 12 , the third male terminal 12 and the fourth male terminal 12 are interconnected via a second semi-annular circuit inside the printed circuit board 11 .

[0083] It is understandable that the first male terminal 12 , the second male terminal 12 , the third male terminal 12 and the fourth male terminal 12 may also be interconnected through other semi-annular circuits inside the printed circuit board 11 , which will not be described in detail in the embodiment of the present invention.

[0084] It is understandable that Figure 3 、 Figure 4 、 Figure 5 The number, position, and layout of the male terminals are for reference only and do not represent the actual male terminal configuration.

[0085] In a possible embodiment, when designing the PCB of the printed circuit board 11, the first copper plating can be used to cover the soldering pad corresponding to the positive pole jack of the first male terminal 12, the soldering pad corresponding to the positive pole jack of the second male terminal 12, the soldering pad corresponding to the positive pole jack of the third male terminal 12, and the soldering pad corresponding to the positive pole jack of the fourth male terminal 12. The second copper plating can be used to cover the soldering pad corresponding to the negative pole jack of the first male terminal 12, the soldering pad corresponding to the negative pole jack of the second male terminal 12, the soldering pad corresponding to the negative pole jack of the third male terminal 12, and the soldering pad corresponding to the negative pole jack of the fourth male terminal 12, and the first male terminal 12, the second male terminal 12, the third male terminal 12, and the fourth male terminal 12 can also be electrically connected to each other.

[0086] The present invention also provides a mobile robot 2. Figure 6, the mobile robot 2 includes a plurality of female terminals 21, a plurality of motor drivers 23, a power supply 22 and a power distribution component 1;

[0087] The power distribution assembly 1 includes a printed circuit board 11 and a plurality of male terminals 12; each of the male terminals 12 is soldered to the printed circuit board 11, and each of the male terminals 12 is electrically connected to each other through internal circuits of the printed circuit board 11;

[0088] The power supply 22 is electrically connected to its corresponding female terminal 21 through a power harness, the motor driver 23 is electrically connected to its corresponding female terminal 21 through a power harness, and the female terminal 21 is detachably electrically connected to the male terminal 12.

[0089] One of the male terminals 12 of the power distribution component 1 can be used as a power input terminal, and can be detachably electrically connected to the female terminal connected to the power harness. The other end of the power harness is electrically connected to the power source 22 (battery). The remaining male terminals 12 of the power distribution component 1 can be used as power output terminals (when the power signal is transmitted to the male terminal 12 serving as the power input terminal, since the male terminals 12 are interconnected through internal lines, the power signal can be transmitted from the male terminal 12 serving as the power input terminal to the remaining male terminals 12, and the remaining male terminals 12 can all output power signals). They are electrically connected to the corresponding motor drivers 23 through the female terminals and the power harness to supply power to the motor driver 23, thereby realizing the power distribution function.

[0090] The male terminals 12 on the printed circuit board 11 can be directly plugged into and electrically connected to the female terminals 21 connected to the power harness (plugging means that the female terminals 21 and 12 can be plugged into each other, with the pins of the male terminals 12 inserted into the sockets of the female terminals 21). After plugging in, the female terminals 21 and the male terminals 12 are mechanically locked together using a snap-on mechanism. This snap-on locking mechanism is simple to operate, difficult to loosen, and highly reliable. The connector formed by the female terminals 21 and the male terminals 12 has a high current capacity, which can meet the requirements of high-power electrical components.

[0091] It is understandable that, since the power signal includes a positive signal and a negative signal, each male terminal includes a positive pin and a negative pin, and each female terminal includes a positive jack and a negative jack.

[0092] In one example, the specifications of the female terminal 21 and the male terminal 12 can be 5.08-2P (the number of poles / ports p is 2, and the distance between the two poles is 5.08 mm). The shape and size of the female terminal 21 are shown as follows. Figure 7a and Figure 7b As shown ( Figure 7a is a front view schematic diagram of the female terminal 21, Figure 7bThe width of the female terminal 21 is 15.10 mm, the height of the female terminal 21 is 18.90 mm, and the protrusion height of the female terminal 21 is 8.70 mm; the shape and size of the male terminal 12 are shown as follows Figure 8a and Figure 8b As shown ( Figure 8a is a front view schematic diagram of the male terminal 12, Figure 8b is a side view schematic diagram of the male terminal 12), the width of the male terminal 12 is 15.00 mm, and the height of the male terminal 12 is 19.20 mm.

[0093] It is understandable that Figure 7a and Figure 8a The shapes of the female terminal 21 and the male terminal 12, the spacing between the poles, and the length dimension calculation method are only shown for illustration, and do not represent the actual shapes and dimensions of the female terminal 21 and the male terminal 12 ( Figure 7a The 5p female terminal is used as an example. Figure 8a The length of the female terminal 21 is 5.08 mm * 2 = 10.16 mm (P * 5.08), and the length of the male terminal 12 is 5.08 mm * 2 + 1.50 mm = 11.66 mm (P * 5.08 + 1.50).

[0094] In the prior art, when power is distributed through a single-to-multiple metal terminal, due to the high current in the power harness, over-the-air (OT) terminals are typically used for wiring connections. Specifically, the cylindrical tail of the OT terminal is inserted into the power harness and secured, while the round head of the OT terminal is fitted over the input / output terminals of the single-to-multiple metal terminal to achieve the connection. This design uses screws for locking, which is difficult to manufacture and assemble, time-consuming, and difficult to ensure reliability. It is prone to loosening, resulting in poor contact.

[0095] In the embodiment of the present utility model, the power distribution function is realized by the male terminals 12 in the power distribution assembly 1, which can improve the power supply method in which each electrical component needs to be connected to the battery through a power harness, and can reduce the use of power harnesses inside the AGV to reduce the occupied space; through the detachable electrical connection between the female terminal 21 and the male terminal 12, the operation is quick and convenient, and the disassembly and maintenance cost is low. Compared with the related technology in which the circular head of the OT terminal is put on the input / output end of a variable metal terminal for wiring connection, the operation is simple, the operation time is short, and the reliability is high.

[0096] In one possible implementation, see Figure 6 , the mobile robot 2 also includes a charging interface 31 and a controller 30;

[0097] The charging interface 31 is electrically connected to a branch on the power harness, and the controller 30 is electrically connected to a branch on the power harness.

[0098] The charging interface 31 can be powered by generating a branch on the power harness, and the controller 30 can be powered by generating a branch on the power harness. For specific reasons, please refer to the subsequent embodiments.

[0099] In one possible implementation, see Figure 6 , the charging interface 31 is electrically connected to the first branch of the first power harness, and the first power harness is the power harness connected to the power supply 22;

[0100] The first motor driver 23 among the plurality of motor drivers 23 is electrically connected to the second branch of the first power harness.

[0101] In one possible implementation, see Figure 6 The controller 30 is electrically connected to a branch on the second power harness, and the second power harness is the power harness to which the motor driver 23 is connected, and the second power harness is not directly connected to the power source 22.

[0102] In one possible implementation,

[0103] The positive pin of the male terminal 12 is plugged into and electrically connected to the positive socket of the female terminal 21 , and the negative pin of the male terminal 12 is plugged into and electrically connected to the negative socket of the female terminal 21 .

[0104] In a possible implementation, the female terminal 21 and the male terminal 12 are mechanically locked by snapping.

[0105] The snap-on locking structure is easy to operate, not easy to loosen, and highly reliable.

[0106] It is understandable that Figure 6 The first power harness and the second power harness are only for reference.

[0107] In one possible implementation, see Figure 9 , the plurality of female terminals include a first female terminal 21, a second female terminal 21, a third female terminal 21 and a fourth female terminal 21, and the plurality of male terminals include a first male terminal 12, a second male terminal 12, a third male terminal 12 and a fourth male terminal 12;

[0109] The positive pin of the second male terminal 12 is electrically connected to the positive socket of the second female terminal 21, and the negative pin of the second male terminal 12 is electrically connected to the negative socket of the second female terminal 21;

[0110] The positive pin of the third male terminal 12 is electrically connected to the positive socket of the third female terminal 21, and the negative pin of the third male terminal 12 is electrically connected to the negative socket of the third female terminal 21;

[0111] The positive pin of the fourth male terminal 12 is plugged into and electrically connected to the positive socket of the fourth female terminal 21 , and the negative pin of the fourth male terminal 12 is plugged into and electrically connected to the negative socket of the fourth female terminal 21 .

[0112] In one possible implementation, see Figure 10 ,based on Figure 9 The mobile robot 2 shown in FIG. 2 further includes a power supply 22 and a first power supply harness;

[0113] The first female terminal 21 is electrically connected to the power source 22 via the first power harness.

[0114] The first female terminal 21 is plugged and electrically connected to the first male terminal 12 , and the first male terminal 12 serves as a power input terminal of the power distribution assembly 1 .

[0115] In one possible implementation, see Figure 10 , the mobile robot 2 further includes a second motor driver 23, a third motor driver 23, a fourth motor driver 23, a second power harness, a third power harness, and a fourth power harness;

[0117] The third female terminal 21 is electrically connected to the third motor driver 23 via a third power harness;

[0118] The fourth female terminal 21 is electrically connected to the fourth motor driver 23 via a fourth power harness.

[0119] The second male terminal 12, the third male terminal 12, and the fourth male terminal 12 of the power distribution component 1 serve as power output terminals (when the power signal is transmitted to the first male terminal 12, since the male terminals 12 are interconnected through internal lines, the power signal can be transmitted from the first male terminal 12 to the remaining male terminals 12, and the remaining male terminals 12 can all output power signals). The second male terminal 12 is electrically connected to the second female terminal 21 connected to the second power harness, and the other end of the second power harness is connected to the second motor driver 23, and the power signal is distributed to the second motor driver 23; the third male terminal 12 is electrically connected to the third female terminal 21 connected to the third power harness, and the other end of the third power harness is connected to the third motor driver 23, and the power signal is distributed to the third motor driver 23; the fourth male terminal 12 is electrically connected to the fourth female terminal 21 connected to the fourth power harness, and the other end of the fourth power harness is connected to the fourth motor driver 23, and the power signal is distributed to the fourth motor driver 23.

[0120] In one possible implementation, see Figure 10 , the mobile robot 2 further includes a controller 30;

[0121] The controller 30 is electrically connected to the second female terminal 21 through a branch of the second power harness and a portion of the second power harness.

[0122] Since the controller 30 is located close to the second power harness and there is only one controller 30 , it is more reasonable and has a better effect to power the controller 30 by generating a branch on the second power harness.

[0123] In one possible implementation, see Figure 10 , the mobile robot 2 further includes a charging interface 31 and a first motor driver 23;

[0124] The charging interface 31 is electrically connected to the power source 22 through the first branch of the first power harness and the first portion of the first power harness;

[0125] The first motor driver 23 is electrically connected to the power source 22 through the second branch of the first power harness and the second portion of the first power harness.

[0126] Since the charging interface 31 and the first motor driver 23 are located close to the first power harness, and are located far away from the power distribution component 1, it is considered that two branches are generated on the first power harness to power the charging interface 31 and the first motor driver 23, which is more reasonable and has a better effect.

[0127] In one possible implementation, see Figure 10, place the power distribution component 1 near the electrical components (second motor driver 23, third motor driver 23, fourth motor driver 23, controller 30) in the first area of ​​the mobile robot 2. The second motor driver 23, third motor driver 23, fourth motor driver 23, and controller 30 can be powered and supplied through the power distribution component 1, while the electrical components (charging interface 31, first motor driver 23) in the second area of ​​the mobile robot 2 are powered by branching the power harness.

[0128] The power supply 22 (battery) in the second area of ​​the mobile robot 2 is a power supply head. The power supply 22 is connected to one end of the first power harness. When the wiring path of the first power harness passes through the charging interface 31, a first branch is generated on the first power harness for connecting to the charging interface 31; when the wiring path of the first power harness passes through the first motor driver 23, a second branch is generated on the first power harness for connecting to the first motor driver 23; the other end of the first power harness is finally connected to the first female terminal 21, and the first female terminal 21 and the first male terminal 12 can be electrically connected in pairs. The power signal of the first power harness is input to the first male terminal 12 of the power distribution component 1. Since the first male terminal 12, the second male terminal 12, the third male terminal 12, and the fourth male terminal 12 are interconnected by internal lines, the power signal can be transmitted from the first male terminal 12 to the second male terminal 12, the third male terminal 12, and the fourth male terminal 12, and the second male terminal 12, the third male terminal 12, and the fourth male terminal 12 can all output power signals.

[0129] The second male terminal 12 is electrically connected to the second female terminal 21 connected to the second power harness, and the other end of the second power harness is connected to the second motor driver 23. The third male terminal 12 is electrically connected to the third female terminal 21 connected to the third power harness, and the other end of the third power harness is connected to the third motor driver 23. The fourth male terminal 12 is electrically connected to the fourth female terminal 21 connected to the fourth power harness, and the other end of the fourth power harness is connected to the fourth motor driver 23. At the same time, a branch is generated on the wiring path of the second power harness for connecting to the controller 30.

[0130] In an embodiment of the present utility model, based on the position layout of each electrical component in the mobile robot 2, the two power distribution methods of the power distribution component 1 and the power harness branching are combined to realize power distribution, which can reduce the repeated path wiring of the power harness (if only the power distribution component 1 is used, the charging interface 31 must also be connected to the power distribution component 1 through the power harness, the first motor driver 23 must also be connected to the power distribution component 1 through the power harness, and the controller 30 must also be connected to the power distribution component 1 through the power harness, resulting in repeated wiring paths of the power harness and increased usage of the power harness), making the routing of the power harness more streamlined and reducing the occupied space.

[0131] In one possible implementation, based on Figure 6 or Figure 10 The mobile robot 2 shown in the figure further includes a metal shell;

[0132] The metal shell covers the power distribution assembly 1 .

[0133] In the embodiment of the present invention, the power distribution assembly 1 is covered by a metal shell to protect the power distribution assembly 1.

[0134] In one possible implementation, based on Figure 6 or Figure 10 The mobile robot 2 shown in the figure further includes a plastic shell;

[0135] The plastic housing covers the power distribution assembly 1 .

[0136] In the embodiment of the present invention, the power distribution assembly 1 is covered by a plastic shell to protect the power distribution assembly 1.

[0137] In addition, the power distribution assembly 1 provided in the embodiment of the present invention can also be applied to other electronic devices, such as electric motorcycles, electric bicycles, etc.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
