[0002] In the prior art, electrical connectors formed by the combination of plugs and sockets are widely used, not only in the field of household appliances, but also in the fields of vehicles and transportation vehicles, such as electric bicycles, electric motorcycles, and electric forklifts. When used, these electrical connectors can achieve electrical connections between multiple electrical components, or between electrical components and battery packs. For example, when the battery pack on an electric vehicle is used to power 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 discharges to provide power.

[0003] The inventors have discovered that the battery pack with an electrical connector in the prior art has at least the following disadvantages:

[0004] 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 conductive, the battery pack discharges, which is prone to arcing and sparking, posing a safety risk.

[0005] Second, existing battery packs only have power supply functions and cannot protect against line short circuits, cannot protect electrical components such as car lights and electric brakes, and cannot prevent runaway situations, posing a safety hazard. Utility Model Content

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.

[0014] In an optional embodiment, the value range of the threshold is not less than 200 kPa.

[0015] In an optional embodiment, the pressure sensor is configured as a bioelectrical induction mechanical sensor, which 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.

[0016] In an optional embodiment, the gripping area is configured as a concave area, and the gripping area is provided with anti-slip grooves.

[0021] The beneficial effects of the multifunctional safety protection type electrical connector, battery pack and electrical equipment provided by the embodiments of the utility model include:

The male 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 on which the male module is installed is plugged into the female 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 activated, which can delay the discharge of the battery pack body.

DETAILED DESCRIPTION

[0035] In the prior art, for example, electric bicycles and electric motorcycles utilize a battery pack 001 for power. This battery pack 001 is typically detachable, allowing it to be removed from the frame 600 and reinstalled after charging. During normal use, after the battery pack 001 is installed on the frame 600, the male terminal on the battery pack 001 electrically mates with the female terminal on the frame 600, forming a circuit with the electric vehicle's electrical system. Discharge from the battery pack 001 can result in arcing and sparking, posing a safety hazard.

[0036] 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.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0041] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0043] In addition, for the convenience of understanding, the professional terms involved in the embodiments of the present invention are explained in detail in the following table:

[0044] Delayed conduction: means that after the female module 100 and the male module 200 are electrically plugged in, the battery pack body 500 delays discharge, and the current output by the battery pack body 500 will not flow to the female module 100 during the plugging process of the female module 100 and the male module 200, but the current will be delivered to the female 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.

[0045] 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.

[0046] 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 to electrically plug and mate 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 between the female end module 100 and the battery pack body 500 when the magnetic induction switch 400 is activated.

[0047] Based on the above, the working mode of the battery pack 001 provided in this embodiment is as follows:

[0048] It should be noted that battery pack 001 can be applied to a variety of electrical devices, including, but not limited to, industrial forklifts, stackers, electric bicycles, electric motorcycles, new energy vehicles, and electrical energy storage. Furthermore, battery pack 001 can be a portable battery pack 001 or a hand-held battery pack 001. Battery pack 001 can be installed on the downtube of any electric vehicle, allowing for top, bottom, and side access. For ease of description, this embodiment uses the application of battery pack 001 to an electric bicycle as an example.

[0049] 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 needed. 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 pathway 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 plugging process, thereby reducing risks.

[0050] Furthermore, the design of the Hall chip 300 can disconnect the power supply to the headlights when the circuits of electrical devices such as headlights are short-circuited or broken due to moisture, water ingress or other reasons, thereby effectively preventing burnout of the wires and lights.

[0051] At the same time, the design of the Hall chip 300 is that when the brake line is damp or water-logged, resulting in a short circuit or open circuit, the Hall chip 300 will directly cut off the power to the brake line, causing the electric vehicle to stop, preventing the problem of the electric vehicle running away due to brake failure and inability to stop during riding, making electric vehicles safer to ride.

[0052] The following embodiments illustrate the details of the battery pack 001 provided in this application.

[0053] In this embodiment, the battery pack body 500 can optionally be configured as a bar-shaped structure. The battery pack body 500 includes a housing 510 and a battery pack mounted within the housing 510. An assembly base 520 is provided at one end of the housing 510, and the male terminal module 200 is mounted at the other end of the housing 510. The outer surface of the housing 510 is provided with a gripping area 530 for the operator to grasp. The gripping area 530 is mounted with a pressure sensor, which is in communication with the magnetic induction switch 400. The pressure sensor is used to obtain information about the pressure 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 exceeds a threshold.

[0054] That is, 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 amount of pressure on the battery pack body 500. The pressure sensor can obtain this pressure information, and when the pressure information is greater than the threshold, it determines that the operator is performing the installation operation of 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 by the activated magnetic induction switch 400, 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 external force applied by the operator controls the opening of the magnetic induction switch 400, which is convenient and flexible to operate and highly reliable.

[0055] Furthermore, there are two gripping areas 530, located on opposite sides of the battery pack body 500. Each gripping area 530 is equipped with a pressure sensor electrically connected to the magnetic induction switch 400. The magnetic induction switch 400 is activated when the pressure information obtained by both pressure sensors exceeds a threshold. Thus, during normal installation of the battery pack body 500, the operator grasps the battery pack body 500 with one hand, with the operator's fingers located on opposite sides of the battery pack body 500. This ensures a smooth grip and reduces slippage, thus saving effort. Furthermore, when grasping and installing the battery pack body 500, the external force exerted by the operator's palm on the battery pack body 500 is detected by the two pressure sensors. The magnetic induction switch 400 is only activated when the pressure information obtained by both pressure sensors exceeds a threshold, thus preventing misoperation and improving the reliability of the battery pack body 500 installation.

[0056] It should be understood that to prevent slipping when gripping the battery pack body 500, which could affect proper installation, the gripping area 530 can be recessed. For example, grooves can be provided on the outer surface of the housing 510, and anti-slip grooves can be provided in the recessed area. This not only helps correct the operator's gripping posture while gripping the battery pack body 500, preventing misoperation, but also prevents slipping and falling, saving time and effort, and making installation of the battery pack body 500 quick and reliable.

[0057] 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 can be 200 kPa-350 kPa. Specifically, the threshold can be set to 200 kPa, 275 kPa or 350 kPa, etc.

[0058] It is worth noting that there are various types of pressure sensors. In this embodiment, the pressure sensor can be configured as a bioelectrical induction mechanical sensor, which is used to activate the magnetic induction switch 400 when human skin contacts the battery pack body 500 and the applied pressure exceeds a threshold. In other words, the pressure sensor not only has the function of obtaining pressure information, but also can determine whether the operator is holding the battery pack body 500. In other words, when the operator is holding the battery pack body 500, the pressure sensor can detect that the battery pack body 500 is being picked up and installed through contact with the operator's skin. When the pressure information obtained by the pressure sensor exceeds the threshold, the magnetic induction switch 400 is activated. In this way, through the multiple safety design, the probability of erroneous operation of the magnetic induction switch 400 is reduced.

[0059] In this embodiment, the battery pack body 500 is optionally provided with a charging port or a discharging port. The charging port allows the battery pack body 500 to be charged using a charging cable when the battery pack body 500 is low on power. The discharging port allows the battery pack body 500 to be discharged to power other electrical devices, such as mobile phones, tablets, flashlights, etc.

[0060] In addition, the power adapter 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 connector, various types of mobile phone connectors, etc.

[0061] In addition, a display screen or a voltage adjustment knob can be configured on the power adapter 700 to facilitate monitoring and flexible adjustment of the charging process. At the same time, the power adapter 700 and the battery pack body 500 are plugged into the power plug 720 of the model designed as needed.

[0062] The battery pack 001 provided in this embodiment can prevent arcing and sparking during installation, ensuring safety and reliability. Furthermore, it can protect electrical appliances such as lights and brakes, thereby improving the safety and reliability of electric vehicles and reducing failure rates.

[0063] This embodiment also provides an electrical device, which includes a vehicle frame 600 and a battery pack 001. The vehicle frame 600 is provided with a snap-in socket 610, on which a positive spring pin 620 and a negative spring pin 630 are provided. The positive spring pin 620 and the negative spring pin 630 are both electrically connected to the magnetic induction switch 400. The male terminal module 200 is mounted on the vehicle frame 600 and arranged with a relative spacing relative to the snap-in socket 610. The end of the battery pack body 500 away from the female terminal module 100 is used to be inserted into the snap-in socket 610. The battery pack 001 can press the positive spring pin 620 and the negative spring pin 630 at the same time. After the positive spring pin 620 and the negative spring pin 630 are pressed into place, a closed circuit is formed with the magnetic induction switch 400, activating the magnetic induction switch 400.

[0064] 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 a 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.

[0065] It should be understood that the position where the battery pack 001 is installed on the vehicle frame 600 is set as needed and is not specifically limited in this embodiment.

[0066] 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.

[0067] In the electrical equipment provided in this embodiment, arcing and sparking are unlikely to occur during installation of the battery pack 001, and the operation is safe and low-risk. In addition, due to the design of the Hall chip 300, the electrical equipment is safe and reliable during use.

[0068] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
