Description

Technical Field

[0001] The present disclosure relates to the technical field of power conversion of power batteries, and particularly to a battery power conversion component and a power distribution device. Background Art

[0002] In recent years, new energy batteries have developed rapidly. Among them, power batteries have relatively large voltage and current and are commonly used as power sources for large electrical equipment such as two-wheeled vehicles. When charging small electrical equipment such as mobile phones and laptop computers through the power output port of the power battery, safety accidents often occur due to the mismatch of voltage and current. Therefore, some manufacturers have made further research and development.

[0003] For example, Chinese Patent Document CN204077908U discloses an electric vehicle with a mobile phone charging function. A battery compartment is provided inside the frame of the electric vehicle, a pedal is provided above the battery compartment, a front fork is provided at the front of the frame, the front fork is connected to a front wheel, the upper end of the front fork is connected to a head and a handlebar, a seat and a rear fork are provided at the rear of the frame, the rear fork is connected to a rear wheel, and a USB mobile phone charger is sleeved on the handlebar. The USB mobile phone charger is connected to a transformer through an electric wire, and the transformer is connected to the battery compartment.

[0004] However, the design of the above-mentioned electric vehicle with a mobile phone charging function has the following problems:

[0005] For the above-mentioned power supply device, although it can charge small electrical equipment by setting an additional interface, a large number of conversion devices are required for the interface to adapt to the voltage and current of small electrical equipment. The conversion devices are large in volume, which not only occupies the internal space of the power battery, resulting in a decrease in the energy density of the power battery, but also generates a large amount of heat during use, increasing the heat dissipation burden of the power battery. At the same time, the interface is set on the surface of the battery shell, which will increase the situation of external moisture entering the power battery through the interface. Summary of the Utility Model

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a battery power conversion component and a power distribution device that can adapt to small electrical equipment.

[0007] The purpose of the present disclosure is achieved by the following technical solutions:

[0008] A battery power conversion component includes a conversion main body and a connecting wire;

[0009] The conversion body includes a housing and an electric energy conversion module. The electric energy conversion module is disposed within the housing. The housing is respectively provided with a connection socket and a mating interface. The connection socket is electrically connected to the mating interface through the electric energy conversion module. The mating interface is used for mating and plugging in a small electrical device. The connection joint of the connection line is electrically connected to the connection socket, and the power supply joint of the connection line is used for electrically connecting to the power output port of the battery of the two-wheeled vehicle.

[0010] In one embodiment, the electric energy conversion module includes a circuit board and a power transfer element. The circuit board is provided with an electronic circuit. The connection socket is electrically connected to the mating interface through the electronic circuit. The power transfer element is disposed on the electronic circuit.

[0011] In one embodiment, the connection socket and the mating interface are respectively fixed on the circuit board.

[0012] In one embodiment, the mating interface is movably disposed in the housing.

[0013] In one embodiment, the housing is further provided with a telescopic opening, and the mating interface is slidably disposed within the telescopic opening.

[0014] In one embodiment, a guiding rail is provided on the inner wall of the housing, and the mating interface is slidably disposed on the guiding rail.

[0015] In one embodiment, the direction in which the mating interface slides relative to the telescopic opening is the first direction, and the direction in which the mating interface slides relative to the guiding rail is the second direction. The first direction and the second direction are parallel to each other.

[0016] In one embodiment, a sliding seat is slidably disposed within the guiding rail, and the mating interface is mounted on the sliding seat; and / or,

[0017] A push-pull member is further slidably disposed on the housing, and the push-pull member is connected to the mating interface.

[0018] In one embodiment, the mating interface is a Mini USB interface, a Micro USB interface or a type-C USB interface; and / or,

[0019] The connection socket and the mating interface are respectively disposed on two end sides of the housing.

[0020] A power distribution device includes a battery of a two-wheeled vehicle and the battery power conversion component of any of the above embodiments. The power supply joint of the connection line is electrically connected to the power output port of the battery of the two-wheeled vehicle.

[0021] Compared with the prior art, the present disclosure has at least the following advantages:

[0022] 1) Since the power connector of the connecting line is electrically connected to the power output port of the two-wheeled vehicle battery, and the connecting joint of the connecting line is electrically connected to the connecting socket of the conversion body, the electric energy of the battery can be transmitted to the connecting socket of the conversion body through the connecting line. Because the connecting socket is electrically connected to the adapter interface through the electric energy conversion module, the electric energy can be transmitted to the adapter interface through the electric energy conversion module. By electrically connecting the adapter interface to the small electrical device, the electric energy can finally be transmitted to the small electrical device. The electric energy changes the current value and voltage value through the electric energy conversion module, and then adapts to the small electrical device.

[0023] 2) Compared with the existing electric vehicle with a mobile phone charging function, the above-mentioned battery electric energy conversion component can be directly electrically connected to the power output port of the two-wheeled vehicle battery through the power connector of the connecting line, without opening an additional interface on the two-wheeled vehicle battery, and thus there is no need to set up an additional conversion device. This not only reduces the occupation of the internal space of the two-wheeled vehicle battery, but also reduces the heat dissipation burden of the two-wheeled vehicle battery, making it safer to use. At the same time, since there is no need to add an additional interface, the situation of moisture seeping into the battery shell surface is also reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To facilitate the understanding of the present disclosure, the present disclosure will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present disclosure can be understood more thoroughly and comprehensively.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present disclosure belongs. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0033] As Figure 1 shown in Figure 2 a battery power conversion component 10 of an embodiment includes a conversion main body and a connection line 200; the conversion main body includes a housing 100 and a power conversion module 110, the power conversion module 110 is disposed in the housing 100, the housing 100 is respectively provided with a connection socket 120 and an adaptation interface 130, the connection socket 120 is electrically connected to the adaptation interface 130 through the power conversion module 110, and the adaptation interface 130 is used for adaptively plugging in a small electrical device; a connection joint 210 of the connection line 200 is electrically connected to the connection socket 120, and a power supply joint 220 of the connection line 200 is used for electrically connecting to a power output port of a two-wheeler battery.

[0034] It can be understood that since the power connector 220 of the connection line 200 is electrically connected to the power output port of the two-wheeled vehicle battery, and the connection connector 210 of the connection line 200 is electrically connected to the connection socket 120 of the conversion body, the electric energy of the battery can be transmitted to the connection socket 120 of the conversion body through the connection line 200. Because the connection socket 120 is electrically connected to the adapter interface 130 through the electric energy conversion module 110, the electric energy can be transmitted to the adapter interface 130 through the electric energy conversion module 110. By electrically connecting the adapter interface 130 to a small electrical device, the electric energy can ultimately be transmitted to the small electrical device. The electric energy passes through the electric energy conversion module 110 to change the current value and voltage value, thereby adapting to the small electrical device.

[0035] It can be understood that compared with the existing electric vehicle with a mobile phone charging function, the above-mentioned battery electric energy conversion component 10 can be directly electrically connected to the power output port of the two-wheeled vehicle battery through the power connector 220 of the connection line 200, without the need to open an additional interface on the two-wheeled vehicle battery, and thus there is no need to set up an additional conversion device. This not only reduces the occupation of the internal space of the two-wheeled vehicle battery, but also reduces the heat dissipation burden of the two-wheeled vehicle battery, making it safer to use. At the same time, since there is no need to add an additional interface, the situation of moisture seeping into the battery shell surface is also reduced.

[0036] Combined with Figure 2 As shown, in this embodiment, the electric energy conversion module 110 includes a circuit board 1110 and a power conversion element 1120. The circuit board 1110 is provided with an electronic circuit. The connection socket 120 is electrically connected to the adapter interface 130 through the electronic circuit, and the power conversion element 1120 is disposed on the electronic circuit. It can be understood that since the connection socket 120 is electrically connected to the adapter interface 130 through the electronic circuit, and by disposing the power conversion element 1120 on the electronic circuit, the electric energy parameters on the electronic circuit are changed, such as changing the resistance of the electronic circuit, so as to adjust the voltage value and resistance value of the electric energy transmitted to the adapter interface 130, and finally make the voltage value and resistance value of the electric energy match the small electrical device adapted and plugged by the adapter interface 130.

[0037] Combined with Figure 2 As shown, specifically, the power conversion element 1120 is a resistor, capacitor, inductor, diode or triode. It can be understood that resistors, capacitors, inductors, diodes or triodes can all be installed in the electronic circuit to adjust the current path and flow rate in the electronic circuit, so that the voltage value and resistance value of the electric energy transmitted to the adapter interface 130 better match the small electrical device.

[0038] It should be specifically noted that the power conversion module 110 can also be implemented using existing circuits and electronic components, which will not be elaborated here as they are not the subject of this application. At the same time, the method of adjusting the path and flow of current in the electronic circuit through the power transfer element 1120 also belongs to the prior art and is not within the scope of protection of this disclosure.

[0039] Combined with Figure 2 As shown, in one embodiment, the connection socket 120 and the adapter interface 130 are respectively fixed on the circuit substrate 1110. It can be understood that since both the connection socket 120 and the adapter interface 130 are fixed on the circuit substrate 1110, the positions of the connection socket 120, the adapter interface 130, and the circuit substrate 1110 can be made compact, so that the electric energy connected to the connection socket 120 can be more stably transmitted to the adapter interface 130 through the circuit substrate 1110. Specifically, the connection socket 120 and the adapter interface 130 can be mounted on the circuit substrate 1110 in the form of SMT chip processing.

[0040] In one embodiment, the adapter interface 130 is movably arranged in the housing 100. It can be understood that because the adapter interface 130 is movably arranged in the housing 100, it can move on the housing 100, and thus the position of the adapter interface 130 can be adjusted arbitrarily. Specifically, the adapter interface 130 can perform movements such as rotation and translation on the housing 100 (not shown in the figure).

[0041] Combined with Figure 2 With Figure 3 As shown, in this embodiment, the housing 100 is also provided with a telescopic opening 140, and the adapter interface 130 is slidably arranged in the telescopic opening 140. It can be understood that since the adapter interface 130 is slidably arranged in the telescopic opening 140, the adapter interface 130 can be slid out of the telescopic opening 140 during use, which is convenient for the adapter interface 130 to connect to small electrical devices. After use, the adapter interface 130 can be slid back into the telescopic opening 140, so that the adapter interface 130 can be quickly stored.

[0042] Combined with Figure 2 As shown, further, the inner wall of the housing 100 is provided with a guide rail 150, and the adapter interface 130 is slidably arranged on the guide rail 150. It can be understood that by slidably arranging the adapter interface 130 on the guide rail 150, the situation of the adapter interface 130 deviating during sliding can be reduced under the guiding action of the guide rail 150.

[0043] Specifically, the direction in which the adaptation interface 130 slides relative to the telescopic port 140 is the first direction, and the direction in which the adaptation interface 130 slides relative to the guide rail 150 is the second direction, and the first direction and the second direction are parallel to each other. It can be understood that because the direction in which the adaptation interface 130 slides relative to the telescopic port 140 and the direction in which the adaptation interface 130 slides relative to the guide rail 150 are parallel to each other, the adaptation interface 130 can extend or retract into the telescopic port 140 more smoothly along the guide rail 150.

[0044] Combined with Figure 2 As shown, in one embodiment, a sliding seat 160 is slidably disposed in the guide rail 150, and the adaptation interface 130 is mounted on the sliding seat 160. It can be understood that by disposing the sliding seat 160 on the guide rail 150, the adaptation interface 130 can be mounted on the sliding seat 160, so that when the adaptation interface 130 is pushed, the adaptation interface 130 can drive the sliding seat 160 to slide on the guide rail 150, thereby avoiding direct contact and wear between the adaptation interface 130 and the guide rail 150.

[0045] Combined with Figure 2 And Figure 3 As shown, in one embodiment, a push member 170 is also slidably disposed on the housing 100, and the push member 170 is connected to the adaptation interface 130. It can be understood that by slidably disposing the push member 170 on the housing 100, since the push member 170 is connected to the adaptation interface 130, the adaptation interface 130 can be driven to slide by pushing the push member 170, thereby more conveniently driving the adaptation interface 130 to extend or retract into the telescopic port 140.

[0046] Combined with Figure 2 As described above, in one embodiment, the adaptation interface 130 is a Mini USB interface, a Micro USB interface, or a type-C USB interface. It can be understood that the adaptation interface 130 can be a Mini USB interface, a Micro USB interface, or a type-C USB interface, etc., so as to be able to specifically adapt to connectors such as mobile phones and laptop computers. Of course, the model of the adaptation interface 130 is not limited, and those skilled in the art can also make other selections according to needs.

[0047] In one embodiment, the electrical connection can be in various forms such as wired connection and wireless connection. It can be understood that the wired connection can be a wire connection or a circuit board connection, etc., and the wireless connection can use a Bluetooth connection or a WIFI (Wireless Fidelity) connection, etc. The specific connection method is not limited, and those skilled in the art can also make other selections according to needs.

[0048] In one embodiment, the connection joint 210 of the connection line 200 is detachably connected to the connection socket 120. It can be understood that by making the connection joint 210 of the connection line 200 detachably connected to the connection socket 120, the connection line 200 and the conversion body can be quickly disassembled and separated after use, thus facilitating storage. Specifically, the connection joint 210 of the connection line 200 is pluggably connected to the connection socket 120. Of course, this is not limited here, and those skilled in the art can make replacements according to needs.

[0049] In one embodiment, the connection socket 120 and the adapter interface 130 are respectively arranged on both end sides of the housing 100. It can be understood that because the connection socket 120 and the adapter interface 130 are respectively arranged on both end sides of the housing 100, the connection socket 120 on one end side of the housing 100 can be electrically connected to the connection joint 210 of the connection line 200, and at the same time, the adapter interface 130 on the other end side of the housing 100 can be adaptively plugged into a small electrical device, so that the small electrical device and the connection line 200 are separately arranged, which can better facilitate use.

[0050] Combined with Figure 1 As shown, the present disclosure also provides a power distribution device, including a two-wheeled vehicle battery and the battery power conversion component 10 of any one of the above embodiments, and the power supply joint 220 of the connection line 200 is electrically connected to the power output port of the two-wheeled vehicle battery. It can be understood that by applying the battery power conversion component 10 of the present disclosure in the power distribution device, by directly electrically connecting the power supply joint 220 of the connection line 200 to the power output port of the two-wheeled vehicle battery, the electric energy of the two-wheeled vehicle battery can be transmitted to the conversion body through the connection line 200. When the adapter interface 130 of the conversion body is electrically connected to a small electrical device, the electric energy in the conversion body can be better adapted to the charging requirements of the small electrical device after being converted by the power conversion module 110.

[0051] Compared with the prior art, the present disclosure has at least the following advantages:

[0052] 1) Since the power supply joint 220 of the connection line 200 is electrically connected to the power output port of the two-wheeled vehicle battery, and the connection joint 210 of the connection line 200 is electrically connected to the connection socket 120 of the conversion body, the electric energy of the battery can be transmitted to the connection socket 120 of the conversion body through the connection line 200. Because the connection socket 120 is electrically connected to the adapter interface 130 through the power conversion module 110, the electric energy can be transmitted to the adapter interface 130 through the power conversion module 110. By electrically connecting the adapter interface 130 to a small electrical device, the electric energy can finally be transmitted to the small electrical device, and the electric energy changes the current value and voltage value through the power conversion module 110, so as to adapt to the small electrical device.

[0053] 2) Compared with the existing electric vehicles with mobile phone charging functions, the above-mentioned battery power conversion component 10 can be directly electrically connected to the power output port of the two-wheeled vehicle battery through the power connector 220 of the connecting wire 200, without the need to open an additional interface on the two-wheeled vehicle battery, and thus there is no need to set up an additional conversion device. This not only reduces the occupation of the internal space of the two-wheeled vehicle battery, but also reduces the heat dissipation burden of the two-wheeled vehicle battery, making it safer to use. At the same time, since there is no need to add an additional interface, the situation of moisture seeping in from the surface of the battery case is also reduced.

[0054] The above embodiments only represent several implementation manners of the present disclosure, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
