For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0065] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two), and similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0070] With the development of science and technology, the application of electrical equipment is becoming more and more extensive. Electrical equipment can be but not limited to mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc.; electrical equipment is usually equipped with a power distribution device to assist the operation of the electrical equipment. Electrical equipment can refer to a device that uses a battery as a power source, and the power source provides electrical energy to the electrical equipment, thereby driving the electrical equipment to work. Electrical equipment is usually equipped with a power distribution device, which is used to control the operation of the high-voltage circuit in the electrical equipment; wherein, the "pressure" in the high-voltage circuit refers to the voltage, and the high-voltage circuit refers to a circuit with a voltage exceeding 60V; the power distribution device includes a plurality of electrical components, and the electrical components are electrically connected through electrical connectors. The electrical components usually have connection terminals, one end of the electrical connector is connected to the connection terminal, and the other end is electrically connected to other electrical components, thereby achieving electrical conduction between the electrical components.

[0071] However, the connecting terminal is usually located between two electrical components, and the distance between the two electrical components is usually set to be larger to provide connection operation space between the electrical connector and the connecting terminal, thereby facilitating the electrical connection between the electrical connector and the connecting terminal. However, the large distance between the electrical components makes the overall space utilization of the entire distribution device low, the structural compactness is poor, and the overall size is large, which is not conducive to improving the performance of the electrical equipment and reducing the manufacturing cost of the electrical equipment.

[0072] In order to improve the structural compactness of a power distribution device, an embodiment of the present application provides a power distribution device, which includes a first electrical component and a second electrical component, a first gap is formed between the first electrical component and the second electrical component, and a first connecting terminal of the first electrical component is located outside the first gap, so that the connection operation space required by the first connecting terminal can be moved outside the first gap, thereby reducing the distance between the first electrical component and the second electrical component, improving the structural compactness of the entire power distribution device, and facilitating reducing the overall dimensions of the entire power distribution device, thereby facilitating improving the performance of electrical equipment and reducing the cost of electrical equipment.

[0073] The power distribution device, battery and power-consuming equipment disclosed in the embodiments of the present application; from the perspective of the development of the market situation, the application of batteries is becoming more and more extensive.

[0093] like Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment of the present application, a power distribution device 100 is provided, which includes a first electrical device 110 and a second electrical device 120. The first electrical device 110 includes a first connecting terminal 111, and the first connecting terminal 111 is used to electrically connect the first electrical device 110 with other electrical devices; a first gap 1001 is formed between the second electrical device 120 and the first electrical device 110; wherein the first connecting terminal 111 is located outside the first gap 1001.

[0094] The power distribution device 100 generally includes a plurality of electrical components, and the first electrical component 110 may refer to an electrical component or a plurality of electrical component integrated electrical modules in the power distribution device 100; for example, the first electrical component 110 may be, but is not limited to, relays, fuses, circuits, current sensors and other components.

When the first electrical connector 151 is electrically connected to the first connecting terminal 111, since the first connecting terminal 111 is located outside the first gap 1001, the connection operation between the first electrical connector 151 and the first connecting terminal 111 can be performed outside the first gap 1001, that is, there is no need to set the connection operation space required for the first connecting terminal 111 in the first gap 1001, thereby reducing the distance between the first electrical device 110 and the second electrical device 120.

[0157] In one embodiment of the present application, Figure 5 , Figure 6 , Figure 7 and Fig. 9As shown, the power distribution device 100 also includes a first shell cover 141 and a mounting base 142. The first shell cover 141 is installed on the mounting base 142. The first shell cover 141 and the mounting base 142 are arranged to form an installation space. The first electrical device 110 and the second electrical device 120 are located in the installation space. The first electrical connector 151 is installed on the first shell cover 141, and the plug interface of the first connecting terminal 111 is arranged toward the first shell cover 141.

[0158] The first shell cover 141 and the mounting seat 142 are connected to form at least part of the outer shell 140 of the power distribution device 100. The first shell cover 141 and the mounting seat 142 can be connected by covering, bolting, bonding, etc.; the installation space can refer to the space formed by the first shell cover 141 and the mounting seat 142 for accommodating the first electrical device 110 and the second electrical device 120. For example, the first shell cover 141 and the mounting seat 142 can jointly define the installation space, and the installation space provides an installation space for the electrical devices of the power distribution device 100. The cover 141 and the mounting seat 142 can separate the electrical device from the external environment, thereby protecting the electrical device; wherein the mounting seat 142 can be a hollow structure with one end open, and the first shell cover 141 can be a plate-like structure, and the first shell cover 141 covers the open side of the mounting seat 142, so that the first shell cover 141 and the mounting seat 142 jointly define the installation space; the first shell cover 141 and the mounting seat 142 can also be hollow structures with one side open, and the open side of the first shell cover 141 covers the open side of the mounting seat 142. Of course, the housing 140 formed by the first shell cover 141 and the mounting seat 142 can be in various shapes, such as a cylinder, a cuboid, etc. The first shell cover 141 and the mounting seat 142 are made of insulating materials, such as: PP (Polypropylene, polypropylene), PE (polyethylene, polyethylene), PVC (Polyvinylchlorid, polyvinyl chloride) and other insulating plastics, so as to provide insulation protection for the first electrical device 110 and the second electrical device 120.

[0159] The first electrical connector 151 is installed on the first shell cover 141. It can be understood that the first electrical connector 151 is connected to the first shell cover 141. Specifically, the first electrical connector 151 can be fixed to the first shell cover 141 by means of threads, clamping, etc.

[0160] The plug interface of the first connection terminal 111 is arranged toward the first shell cover 141. Specifically, the opening of the plug hole 11111 of the first connection terminal 111 is arranged opposite to the first shell cover 141. In this way, when assembling, while the first electrical device 110 is installed on the first shell cover 141, the second end of the first electrical connector 151 installed on the first shell cover 141 can be inserted into the first connection terminal 111. In this way, the assembly of the first electrical device 110 and the first shell cover 141 and the electrical plugging of the first connection terminal 111 can be completed at the same time, which is beneficial to improving the assembly efficiency of the power distribution device 100; or After the first electrical component 110 and the second electrical component 120 are installed on the mounting base 142, the first shell cover 141 is buckled on the mounting base 142. Since the first connecting terminal 111 is facing the first shell cover 141, during the buckling process of the first shell cover 141 and the mounting base 142, the second end of the first electrical connector 151 installed on the first shell cover 141 can be automatically electrically connected with the first connecting terminal 111. In this way, the assembly of the first electrical component 110 and the first shell cover 141 and the electrical connection of the first connecting terminal 111 can be completed at the same time, which is beneficial to improving the assembly efficiency of the power distribution device 100.

Compared with manual plugging, the space required for plugging is small, which is beneficial to reducing the distance between the first electrical device 110 and the second electrical device 120, and improving the structural compactness of the distribution device 100.

[0162] In another embodiment, the plugging port of the second connection terminal 121 may be disposed toward the first shell cover 141 to improve production efficiency; of course, the plugging port of the second connection terminal 121 may not be disposed toward the first shell cover 141 .

[0164] In actual application, when the power distribution device 100 is in working state, the first shell cover 141 can be located at the bottom of the mounting seat 142, or at the side of the mounting seat 142, or at the top of the mounting seat 142, which can be selected according to actual needs.

[0165] In one embodiment of the present application, Fig. 9 and Fig.10 As shown, the first electrical connector 151 is embedded in the first shell cover 141 .

[0166] The first electrical connector 151 is buried in the first shell cover 141. It can be understood that the first electrical connector 151 is located inside the first shell cover 141. In other words, the first shell cover 141 is covered outside the first electrical connector 151. It should be noted that the first end and the second end are exposed to the first shell cover 141 to facilitate electrical connection with other electrical components and the first connection terminal 111.

[0167] By adopting the technical solution of this embodiment, the first shell cover 141 can protect the first electrical connector 151, thereby improving the reliability of the use of the distribution device 100; in addition, the first electrical connector 151 is located inside the first shell cover 141, and the overall structure is compact, which is also conducive to reducing the overall size of the distribution device 100.

This manufacturing method is simple, and the connection strength between the first electrical connector 151 and the first shell cover 141 is good, which is beneficial to improving the reliability of the use of the distribution device 100.

[0170] In one embodiment of the present application, Fig.12 and Fig.13 As shown, the first electrical device 110 is a relay 110a; the relay 110a includes a switch unit 114, and the first connecting terminal 111 is electrically connected to the switch unit 114; the mounting seat 142 is configured with a first accommodating cavity 1421, and the switch unit 114 is exposed in the first accommodating cavity 1421.

[0171] The relay 110a may refer to an electrical device for controlling the on and off of a circuit. Specifically, the relay 110a includes components such as an electromagnet, a coil, and a contact. When the input quantity (such as voltage, current, temperature, etc.) of the input coil reaches a specified value, the electromagnet moves under the magnetic force of the coil, and the movement of the electromagnet drives the movement of the contact, thereby changing the on and off state of the controlled circuit. The switch unit 114 may refer to the main component in the relay 110a that plays a role in switch control, that is, a unit composed of components such as an electromagnet, a coil, and a contact in the relay 110a. The first connection terminal 111 is electrically connected to the switch unit 114, and the switch unit 114 is electrically connected to other electrical components except the first electrical device 110 through the first connection terminal 111.

[0172] The first accommodating cavity 1421 may refer to a cavity formed by the mounting seat 142 and used to accommodate the switch unit 114 .

[0173] The switch unit 114 is exposed in the first accommodating cavity 1421. It can be understood that the switch unit 114 is not wrapped by a shell, but is directly exposed in the first accommodating cavity 1421, that is, the cavity wall of the first accommodating cavity 1421 can be directly used as the shell of the relay 110a, that is, the first electrical device 110 is the relay 110a after the shell is removed, and the mounting seat 142 is integrated with the shell of the relay 110a to form an integrated structure, which is beneficial to reduce the manufacturing cost.

[0174] By adopting the technical solution of this embodiment, the switch unit 114 of the relay 110a is directly exposed in the first accommodating cavity 1421. In this way, in the power distribution device 100, the space occupied by the housing of the relay 110a can be saved, the structural compactness of the power distribution device 100 is improved, and it is beneficial to improve the performance of the power distribution device 100 and reduce the manufacturing cost; in addition, the relay 110a is usually a larger component in the power distribution device 100, and eliminating the housing of the relay 110a can save a large space for the power distribution device 100, thereby effectively improving the structural compactness of the power distribution device 100.

[0175] In one embodiment, the first connection terminal 111 may be a connection terminal derived from the coil of the relay 110a, or may be a connection terminal derived from the contact of the relay 110a, or may be a high-voltage sampling terminal of the relay 110a. Fig. 9 , Fig.10 and Fig.11 As shown, the first electrical device 110 also includes a first conductive member 112, the first conductive member 112 electrically connects the switch unit 114 and the body 1111, and the first conductive member 112 is made of a conductive material, such as copper, aluminum, etc. For example, the first conductive member 112 is a copper bar. The first conductive member 112 and the body 1111 are an integral structure or a split structure. Among them, the first conductive member 112 and the body 1111 are an integrated structure. It can be understood that the first conductive member 112 and the body 1111 can be an integrated structure obtained by an integrated molding method such as integral casting, integral cutting, etc.

[0176] The first conductive member 112 and the body 1111 are of a split structure. It can be understood that the first conductive member 112 and the body 1111 can be separated into two separate parts. For example, the first conductive member 112 and the body 1111 can be connected by a detachable connection method such as screw connection or clamping; or, the first conductive member 112 and the body 1111 are connected by a fixed connection method such as welding; or, the end of the first conductive member 112 can also be inserted into the plug hole 11111, and the elastic member 1112 pushes against the plug hole 11111. The end of the first conductive member 112 abuts against the wall of the plug hole 11111, thereby realizing elastic clamping of the first conductive member 112, wherein the end of the first conductive member 112 and the second end may be located on the same side of the elastic member 1112, or on opposite sides of the elastic member 1112; in another embodiment, two elastic members 1112 are provided in the plug hole 11111, and the second end is inserted between the two elastic members 1112, and the two elastic members 1112 clamp the second end, thereby realizing elastic clamping of the second end. The materials of the first conductive member 112 and the body 1111 may be the same or different.

[0178] In one embodiment of the present application, the first electrical device 110 is a resistor, a fuse or a current sensor; and / or the second electrical device 120 is a relay, a resistor, a fuse or a current sensor. It is understandable that the first electrical device 110 can be any one of the resistor, the fuse and the current sensor in the power distribution device 100, and similarly, the second electrical device 120 can be any one of the resistor, the fuse and the current sensor in the power distribution device 100.

[0179] A fuse may refer to an electrical component in a circuit that cuts off the current by fusing itself when the current abnormally rises to a preset value. The fuse plays a role in protecting the safe operation of the circuit.

[0180] Resistors can refer to electrical components in a circuit that have a certain resistance to the flow of current.

[0181] The current sensor may refer to a detection device that can sense the information of the measured current and convert the sensed information into an electrical signal that meets certain standard requirements according to a certain rule.

The first electrical device 110, the second electrical device 120 and the third electrical device 130 can enter the corresponding cavity through the corresponding openings to facilitate the assembly of the power distribution device 100.
