Description

Technical Field

[0001] This utility model relates to the field of charging gun head technology, specifically a charging gun head lighting and charging operation prompt sound device. Background Technology

[0002] With the development of new energy vehicles, the supporting charging devices are becoming more and more popular. At present, there is a strong symbiotic relationship between charging devices and the development of new energy vehicles. The charging gun head is the physical interface connecting the charging device and the car. After the new national standard unified the interface in 2015, the charging gun head is divided into DC gun and AC gun. The charging process of the car is to connect the charging gun head and the body interface.

[0003] Currently available charging guns do not have lighting functions, making it extremely inconvenient to charge in low-light conditions at night. Users need to use other lighting equipment to help locate the vehicle's charging port before they can charge their vehicles. The nighttime user experience is extremely poor and the convenience is very low.

[0004] In addition, the current charging guns do not have an audible prompt function, and setting the charging current, time and other functions is not very convenient for blind operation. Furthermore, there is no prompt after the charging gun is plugged into the vehicle to indicate whether it is charging normally. You have to go back to the car to check the car's infotainment system to see if it is charging normally, which is not a very good user experience. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a charging gun head lighting and charging operation prompt sound device. By adding lighting and voice prompt devices to the charging gun head, it solves the problems of existing charging gun heads being inconvenient for charging vehicles at night when there is insufficient light, and the inability to easily set charging gun parameters during daily use, which makes it difficult to quickly know whether the vehicle has started charging normally.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a charging gun head illumination and charging operation prompt sound device, including a charging gun body, a charging cable disposed at the bottom of the charging gun body, a plug disposed at the left end of the charging gun body, a pinhole opened on the end face of the plug, an illumination hole disposed on the surface of the plug next to the pinhole, a locking plate installed on the top of the charging gun body, a locking buckle disposed at one end of the locking plate extending to the outside of the charging gun body, a button disposed on the surface of the other end of the locking plate, the button being slidably connected to the top shell of the charging gun body, and a sound-emitting device disposed inside the charging gun body.

[0007] Furthermore, an LED light source is installed inside the lighting hole, which is used for nighttime illumination.

[0008] Furthermore, the plug is used for charging port insertion, and terminals are provided in the pinhole.

[0009] Furthermore, the end of the locking buckle has a hook-shaped structure, which is used to engage with the charging port. Rotating seats are provided on both sides of the locking plate, and the locking plate is rotatably connected to the housing of the charging gun body through the rotating seats.

[0010] Furthermore, the bottom of the button and the charging gun body are connected by a spring, and a push switch is located inside the charging gun body below the button.

[0011] Furthermore, the sound-generating device includes a charging gun circuit board disposed in the charging gun body, and a speaker module for generating sound is disposed on the charging gun circuit board.

[0012] Furthermore, the charging gun circuit board and the push switch are electrically connected. When the push switch is pressed, the charging gun circuit board controls the charging gun to cut off the power.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This charging gun features a head lighting and charging operation prompt sound device. An additional lighting structure on the charging gun's plug provides nighttime illumination, greatly enhancing convenience for nighttime vehicle charging. Furthermore, an internal sound device is integrated into the circuitry, allowing users to clearly determine success when setting charging current, scheduling time, or other operations. Different operations and states are accompanied by corresponding audible prompts, transforming the charging status assessment from solely relying on visual perception to a comprehensive visual and auditory experience, significantly improving vehicle charging convenience.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This embodiment of a charging gun head lighting and charging operation prompt sound device includes a charging gun body 1, a charging cable 2 disposed at the bottom of the charging gun body 1, a plug 3 disposed at the left end of the charging gun body 1, a pinhole opened on the end face of the plug 3, an illumination hole 4 disposed on the surface of the plug 3 next to the pinhole, an LED light source disposed inside the illumination hole 4 for nighttime illumination, a protective light-transmitting glass added to the illumination hole 4, a locking plate 5 installed at the top inside the charging gun body 1, a locking buckle 6 disposed at one end of the locking plate 5 extending to the outside of the charging gun body 1, a button 7 disposed on the surface of the other end of the locking plate 5, the button 7 being slidably connected to the top shell of the charging gun body 1, and a sound-emitting device 8 disposed inside the charging gun body 1.

[0022] In this embodiment, when there is insufficient light, the lighting structure at the end can provide illumination for connecting the plug 3 and the charging port, making operation convenient. In addition, the sound device 8 can play voice prompts in real time, such as whether the plug 3 is connected properly and whether it is charging, making the overall convenience better.

[0023] It is worth noting that the lighting structure is integrated into the charging gun head, which enables the charging gun to have a lighting function while facilitating assembly and not compromising the product's waterproof performance.

[0024] It should be noted that plug 3 is used for charging port insertion, and the pinhole has terminals. According to national standards, the pinhole is either seven-hole or nine-hole.

[0025] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the end of the locking buckle 6 is a hook-shaped structure. The locking buckle 6 is used to engage with the charging port. Rotating seats are provided on both sides of the locking plate 5. The locking plate 5 is rotatably connected to the housing of the charging gun body 1 through the rotating seats.

[0026] It should be noted that the bottom of button 7 is connected to the charging gun body 1 by a spring, and a push switch is located inside the charging gun body 1 below button 7. The elasticity of the spring causes button 7 to be lifted up after it is released, and the button and the push switch are separated.

[0027] In this embodiment, when the plug 3 is inserted, a person needs to press the button 7, and after compressing the spring, one end of the locking plate 5 moves downward. The rotating seat serves as the fulcrum, forming a rocker structure, so that one end of the locking buckle 6 is raised. A corresponding slot is provided at the charging port, so that when the button 7 is released, the locking buckle 6 falls down and engages with the slot.

[0028] Please see Figure 3 In this embodiment, the sound-generating device 8 includes a charging gun circuit board 81 disposed in the charging gun body 1. The charging gun circuit board 81 is provided with a speaker module 82 for sound generation. The charging gun circuit board 81 is electrically connected to a push switch (the push switch is a conventional solution, so the structure and connection of the push switch will not be described in detail). When the push switch is pressed, the charging gun circuit board 81 controls the charging gun to cut off the power.

[0029] In this embodiment, the speaker module 82 can emit a prompt sound and is connected to the charging gun circuit board 81 for easy control. The charging gun circuit board 81 is provided with a chip module for control and storage (the sound-emitting device is a speaker structure used to play specific sounds, or it can be a buzzer structure used to provide prompts by sounding). The control unit is a control scheme of drive circuit or signal interaction (which is common knowledge). The storage module is used to store programmed voice prompts, which, after being encoded in a state, emit corresponding prompt sounds in corresponding situations.

[0030] It should be noted that the installation location of the sound-generating device 8 should avoid high-voltage cables, and electromagnetic interference should be suppressed by rubber shock-absorbing pads.

[0031] The working principle of the above embodiments is as follows:

[0032] During operation, the charging gun body 1 is connected to the charging device or power supply via the charging cable 2. Charging is initiated after the plug 3 is inserted into the charging port. When the plug 3 is inserted, an LED light source provides illumination, making it convenient to illuminate the plug 3 and charging port in low-light environments, thus facilitating operation. During operation, the operator needs to press button 7 to lower one end of the locking plate 5 and contact the press switch, which cuts off the power to the charging gun through the circuit, increasing safety. After the locking buckle 6 connects with the slot of the charging port, releasing button 7 facilitates locking and increases the stability of the connection. At the same time, the elasticity of the spring causes the locking plate 5 to return to its original position. An internal sound device 8 is added to enable voice broadcasting during operation, providing real-time voice prompts throughout the entire charging gun operation process, such as "Charging gun is connected" and "Charging has started," providing convenience for the charging operation.

[0033] It should be noted that the charging gun proposed in this utility model is an existing technology structure, so it will not be described in detail. At the same time, the power supply is also common knowledge in the field, so the control method and circuit connection will not be explained in detail in this utility model.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
