[0002] In the prior art, the electrical connector formed by the combination of a plug and a socket is widely used, not only in the field of household appliances, but also in the fields of vehicles and transportation tools, such as electric bicycles, electric motorcycles, and electric forklifts. When the electrical connector is used, it can realize the electrical connection of multiple electrical components, or realize the electrical connection between electrical components and battery packs. For example, when the battery pack on an electric vehicle is powered by other electrical devices, it is necessary to first install the battery pack on the battery holder on the frame so that the entire circuit forms a closed loop, and the battery pack is discharged to provide power.

[0003] The inventor has found that the battery pack with an electrical connector in the prior art has at least the following disadvantages: First, when the battery pack is installed on the battery holder, it is plugged into the plug on the battery holder. At this time, since the battery pack is turned on, the battery pack discharges, which may easily cause arcing and sparking, posing a safety risk. Second, the existing battery pack only has the function of power supply, and cannot protect the line short circuit, cannot protect the electrical components such as the lights and electric brakes, and cannot prevent the car from running away, which poses a safety hazard. Summary of the invention

[0004] The purpose of the present invention includes providing a multifunctional safety protection type electrical connector, battery pack and electrical equipment, which can pre-discharge arc and spark phenomena, and can also protect against circuit short circuits, reduce the probability of damage to electrical components such as lights and brakes, and improve operating stability.

[0006] In a second aspect, the present invention provides a battery pack, the battery pack comprising: The battery pack body and the multifunctional safety protection type electrical connector described in the above-mentioned embodiment, the female end module is installed at one end of the battery pack body, and the battery pack body is used to be installed on the vehicle frame.

[0007] In an optional embodiment, a holding area for an operator to hold is provided on the battery pack body, and a pressure sensor is installed in the holding area. The pressure sensor is communicatively connected with the magnetic induction switch. The pressure sensor is used to obtain pressure information applied by the operator to the battery pack body, and activate the magnetic induction switch on the male terminal module when the pressure information is greater than a threshold.

[0008] In an optional embodiment, there are two holding areas, which are distributed on opposite sides of the battery pack body. Each holding area is equipped with a pressure sensor electrically connected to the magnetic induction switch. When the pressure information obtained by the two pressure sensors is greater than a threshold, the magnetic induction switch is activated.

[0009] In an optional implementation, the threshold value range is not less than 200 kPa.

[0010] In an optional embodiment, the pressure sensor is configured as a bio-electromechanical sensor, and the bio-electromechanical sensor is used to activate the magnetic induction switch when human skin contacts the battery pack body and the applied pressure is greater than a threshold value.

[0011] In an optional embodiment, the gripping area is configured as a concave area, and the gripping area is provided with anti-slip grooves.

[0012] In an optional embodiment, a charging interface or a discharging interface is provided on the battery pack body.

[0013] In a third aspect, the present invention provides an electrical device, the electrical device comprising: The battery pack according to any one of the preceding embodiments.

[0014] In an optional embodiment, the electrical equipment also includes a frame, a clamping seat is provided on the frame, a positive spring pin and a negative spring pin are provided on the clamping seat, and the positive spring pin and the negative spring pin are both electrically connected to the magnetic induction switch; the male end module is installed on the frame and arranged relatively spaced apart from the clamping seat; the end of the battery pack body away from the female end module is used to be inserted into the clamping seat, and the battery pack can press the positive spring pin and the negative spring pin at the same time, and after the positive spring pin and the negative spring pin are pressed into place, they form a circuit closed loop with the magnetic induction switch and activate the magnetic induction switch.

[0015] The beneficial effects of the multifunctional safety protection type electrical connector, battery pack and electrical equipment provided by the embodiments of the present invention include: In summary, the multifunctional safety protection type electrical connector provided in this embodiment is installed with a Hall chip on the female end module and a magnetic induction switch on the male end module. When in use, the female end module is installed on the battery pack body, and the female end module is electrically connected to the battery pack body. The male end module is installed on a supporting structure such as a vehicle frame. When the battery pack body is assembled with the vehicle frame, the end of the battery pack body with the male end module installed is plugged into the female end module. At this time, a path is formed between the battery pack body and the electrical components of the electrical equipment. Due to the design of the Hall chip and the magnetic induction switch, when the magnetic induction switch is activated, the Hall chip is started, which can delay the discharge of the battery pack body. In this way, no current flows when the male end module and the female end module are plugged into each other, which can avoid arcing and sparking of the battery pack body during the plugging process, thereby reducing risks.

[0016] In addition, the design of the Hall chip can disconnect the power supply to the headlights when the circuits of electrical equipment such as headlights are short-circuited or open-circuited due to moisture, water ingress or other reasons, effectively preventing burnt wires and lights.

[0017] At the same time, the design of the Hall chip is that when the brake line is damp or water-logged and short-circuited or open-circuited, the Hall chip will directly cut off the power to the brake line, stopping the electric vehicle. This prevents the problem of the electric vehicle running away due to brake failure and inability to stop during riding, making electric vehicles safer to ride. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In the prior art, for example, electric bicycles or electric motorcycles use a battery pack 001 for power supply. The battery pack 001 is generally configured as a detachable structure, which can be removed from the frame 600 and installed on the frame 600 after charging. In normal use, after the battery pack 001 is installed on the frame 600, the male end of the battery pack 001 is electrically plugged into the female end of the frame 600, and the battery pack 001 and the electric system of the electric vehicle form a circuit. When the battery pack 001 discharges, arcs and sparks will occur, which poses a safety hazard.

[0022] In view of this, the designer provides a multifunctional safety protection electrical connector, which can delay the discharge of the battery pack 001 after the battery pack 001 is plugged into the frame 600, thereby avoiding arcing and sparking during the plugging process and improving safety.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0028] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0029] In addition, for ease of understanding, the professional terms involved in the embodiments of the present invention are explained in detail as follows: Delayed conduction: refers to the delayed discharge of the battery pack body 500 after the female-end module 100 and the male-end module 200 are electrically plugged in. The current output by the battery pack body 500 will not flow to the female-end module 100 during the plugging process of the female-end module 100 and the male-end module 200, but the current will be transmitted to the female-end module 100 after the delay set time. For example, the set time can be 10s, etc. The set time can be adjusted as needed, and is not exhaustively listed in this embodiment.

[0030] The overall structure, working principle and technical effects of the battery pack 001 provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0031] Please combine Figure 1-Figure 7 In this embodiment, the battery pack 001 includes a battery pack body 500 and a multifunctional safety protection type electrical connector. The multifunctional safety protection type electrical connector includes a female end module 100, a male end module 200, a Hall chip 300 and a magnetic induction switch 400; the female end module 100 is used for electrical plug-in cooperation with the male end module 200, the female end module 100 is installed at one end of the battery pack body 500, and the two are electrically connected. The Hall chip 300 is installed on the female end module 100, and the magnetic induction switch 400 is installed on the male end module 200. The Hall chip 300 is used to delay the conduction of the female end module 100 and the battery pack body 500 when the magnetic induction switch 400 is activated.

[0032] Based on the above, the working mode of the battery pack 001 provided in this embodiment is as follows: It should be noted that the battery pack 001 can be applied to a variety of electrical equipment, such as but not limited to: industrial equipment forklifts, stackers, electric bicycles, electric motorcycles, new energy and electric energy storage. In addition, the battery pack 001 can be a portable battery pack 001, a hand-grabbed battery pack 001, etc. The installation position of the battery pack 001 can cover all lower tubes of electric vehicles, and the battery pack 001 can be matched with upper, lower, side and other methods. In this embodiment, for the convenience of description, the battery pack 001 is applied to an electric bicycle as an example for description.

[0033] When in use, the male end module 200 can be fixed on the frame 600 of the electric bicycle. Specifically, the male end module 200 can be fixed on the lower tube of the frame 600. It can be located on the lower side, upper side, left side or right side of the lower tube as required. When the battery pack body 500 is assembled with the frame 600, the end of the battery pack body 500 on which the female end module 100 is installed is plugged into the male end module 200. At this time, the battery pack body 500 forms a passage with the power supply system of the electric bicycle. Due to the design of the Hall chip 300 and the magnetic induction switch 400, when the magnetic induction switch 400 is activated, the Hall chip 300 senses the signal sent by the magnetic induction switch 400, and the Hall chip 300 starts, which can delay the discharge of the battery pack body 500. In this way, when the male end module 200 and the female end module 100 are plugged into each other, the current output by the battery pack body 500 will not flow to the female end module 100, which can avoid arcing and sparking in the battery pack body 500 during the plug-in process, thereby reducing the risk.

[0034] In addition, the design of the Hall chip 300 can disconnect the power supply to the headlights when the circuit of the electrical equipment, such as the headlights, is short-circuited or broken due to moisture, water ingress or other reasons, thereby effectively preventing the wires and lights from burning out.

[0035] At the same time, the design of the Hall chip 300 is that when the brake line is damp or water-logged and short-circuited or open-circuited, the Hall chip 300 will directly cut off the power to the brake line and stop the electric vehicle, preventing the problem of the vehicle running away due to brake failure and inability to stop during riding, making electric vehicles safer to ride.

[0036] The following embodiments illustrate the details of the battery pack 001 provided in this application.

[0037] In this embodiment, optionally, the battery pack body 500 can be set as a bar structure, the battery pack body 500 has a shell 510 and a battery pack installed inside the shell 510, one end of the shell 510 is provided with an assembly card seat 520, and the other end of the shell 510 is installed with a male terminal module 200. The outer surface of the shell 510 is provided with a gripping area 530 for the operator to hold, and the gripping area 530 is installed with a pressure sensor, which is connected to the magnetic induction switch 400 for communication. The pressure sensor is used to obtain the pressure information applied by the operator to the battery pack body 500, and activate the magnetic induction switch 400 on the male terminal module 200 when the pressure information is greater than the threshold.

[0038] That is to say, when the operator picks up the battery pack body 500 and installs it on the frame 600, the operator holds the battery pack body 500 with his hand and applies a certain pressure on the battery pack body 500. The pressure sensor can obtain the pressure information, and when the pressure information is greater than the threshold, it is determined that the operator is performing the operation of installing the battery pack body 500. At this time, the magnetic induction switch 400 is activated. When the male end module 200 of the battery pack body 500 is plugged into the female end module 100, the Hall chip 300 detects the magnetic field information emitted after the magnetic induction switch 400 is activated, thereby controlling the delayed discharge of the battery pack body 500. When installing the battery pack body 500, the operator needs to apply force to the battery pack body 500 to plug it into the frame 600. The magnetic induction switch 400 is turned on by the external force applied by the operator. The operation is convenient and flexible, and the reliability is high.

[0039] Furthermore, there are two gripping areas 530, which are distributed on opposite sides of the battery pack body 500. Each gripping area 530 is installed with a pressure sensor electrically connected to the magnetic induction switch 400. When the pressure information obtained by the two pressure sensors is greater than the threshold, the magnetic induction switch 400 is activated. In this way, when installing the battery pack body 500 under normal circumstances, the operator holds the battery pack body 500 with one hand, and the operator's fingers are distributed on opposite sides of the battery pack body 500, so that the battery pack body 500 is not easy to slip and is more labor-saving. In addition, when grasping the battery pack body 500 and installing it, the external force exerted by the operator's palm on the battery pack body 500 is respectively obtained by the two pressure sensors, and the magnetic induction switch 400 is activated only when the pressure information obtained by the two pressure sensors is greater than the threshold, thereby avoiding the occurrence of misoperation and improving the reliability of the installation of the battery pack body 500.

[0040] It should be understood that when holding the battery pack body 500, in order to avoid slipping and affecting the normal installation of the battery pack body 500, the holding area 530 can be set as a recessed area, for example, a groove is set on the outer surface of the shell 510, and anti-slip grooves are set in the recessed area. First, the recessed area facilitates the correction of the operator's holding posture of the battery pack body 500 to avoid misoperation, and second, it plays a role in preventing slipping and falling, saving time and effort in operation, and the battery pack body 500 is convenient and reliable to install.

[0041] It should be noted that the value range of the threshold is not less than 200 kPa. For example, in this embodiment, the value range of the threshold may be 200 kPa-350 kPa. Specifically, the threshold may be set to 200 kPa, 275 kPa or 350 kPa, etc.

[0042] It is worth noting that there are various types of pressure sensors. In this embodiment, the pressure sensor can be set as a bioelectric induction mechanical sensor, which is used to activate the magnetic induction switch 400 when the human skin contacts the battery pack body 500 and the applied pressure is greater than the threshold. In other words, the pressure sensor not only has the function of obtaining pressure information, but also can obtain whether the operator is holding the battery pack body 500, that is, when the operator holds the battery pack body 500, the pressure sensor can know that the battery pack body 500 is being picked up and installed through the operator's skin, and when the pressure information obtained by the pressure sensor is greater than the threshold, the magnetic induction switch 400 is activated. In this way, through multiple insurance designs, the probability of misoperation of the magnetic induction switch 400 is low.

[0043] In this embodiment, a charging interface or a discharging interface is optionally provided on the battery pack body 500. The charging interface can charge the battery pack body 500 using a charging cable when the battery pack body 500 is low on power. The discharging interface can output the power of the battery pack body 500 to power other electrical appliances, such as mobile phones, tablets, flashlights, etc.

[0044] In addition, the power adapter cable can be configured to transmit power to different types of electrical appliances. The external connector 710 of the power adapter 700 can be a USB, a computer charging round head, various types of mobile phone connectors, etc.

[0045] In addition, a display screen or a voltage adjustment knob may be configured on the power adapter 700 to facilitate monitoring and flexible adjustment of the charging process. At the same time, the model of the power transmission plug 720 of the power adapter 700 plugged into the battery pack body 500 is designed as required.

[0046] The battery pack 001 provided in this embodiment can prevent arcing and sparking during installation, and is safe and reliable. At the same time, it can also protect electrical appliances such as lights and brakes, improve the safety and reliability of electric vehicles, and reduce the failure rate.

[0047] This embodiment also provides an electric device, which includes a vehicle frame 600 and a battery pack 001. A card connector 610 is provided on the vehicle frame 600, and a positive spring pin 620 and a negative spring pin 630 are provided on the card connector 610, and the positive spring pin 620 and the negative spring pin 630 are both electrically connected to the magnetic induction switch 400; the male end module 200 is mounted on the vehicle frame 600 and arranged with a relative interval with the card connector 610; the end of the battery pack body 500 away from the female end module 100 is used to be plugged into the card connector 610, and the battery pack 001 can press the positive spring pin 620 and the negative spring pin 630 at the same time, and after the positive spring pin 620 and the negative spring pin 630 are pressed into place, a circuit closed loop is formed with the magnetic induction switch 400 and the magnetic induction switch 400 is activated.

[0048] It should be understood that the first scheme of activating the magnetic induction switch 400 by the positive spring pin 620 and the negative spring pin 630 and the second scheme of activating the magnetic induction switch 400 by using the pressure sensor can be used independently or in series. When used independently, the magnetic induction switch 400 is activated when one of the first scheme and the second scheme meets the regulation. When the two are used in series, the magnetic induction switch 400 is activated when both the first scheme and the second scheme meet the regulation.

[0049] It should be understood that the position where the battery pack 001 is installed on the vehicle frame 600 is set as required and is not specifically limited in this embodiment.

[0050] In addition, electrical equipment may not be limited to industrial equipment such as forklifts, stackers, electric bicycles, electric motorcycles, new energy and electric energy storage.

[0051] The electrical equipment provided in this embodiment is not prone to arcing and sparking when the battery pack 001 is installed, and the operation is safe with low risk. In addition, due to the design of the Hall chip 300, the electrical equipment is safe and reliable during use.

[0052] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
