Description

Technical Field

[0001] This application relates to the field of charging technology, and in particular to a charging gun and charging device. Background Technology

[0002] Currently, more and more charging guns are equipped with lighting structures to prevent users from being unable to quickly align the charging gun with the charging dock of the product being charged in dimly lit environments. However, most existing charging guns directly mount the lighting structure on the outside of the charging gun, which not only increases the size of the charging gun but also affects its aesthetics. Summary of the Invention

[0003] This application provides a charging gun and charging equipment to solve the problem that the setting of the lighting structure in the known technology leads to an increase in the size of the charging gun or affects its aesthetics.

[0004] This application provides a charging gun, including a housing, a charging head, and a light-emitting element. The housing has a mounting cavity for a connecting wire to pass through, one end of which is electrically connected to a power supply device. The charging head is detachably connected to one end of the housing and electrically connected to the other end of the connecting wire. The light-emitting element is connected to the charging head and is located within the mounting cavity. The charging head is configured to guide the light emitted by the light-emitting element to the outside of the charging head.

[0005] In one possible implementation, the charging gun further includes a wire holder disposed within the mounting cavity. The wire holder is located at one end of the charging head near the housing, and a mounting groove is formed on the side of the wire holder near the charging head. The light-emitting element is housed within the mounting groove and is positioned facing the charging head.

[0006] In one possible implementation, the lead wire socket is detachably connected to the housing or the charging head, and the charging head is sealed to the housing to seal the mounting cavity where the light-emitting element is located.

[0007] In one possible implementation, the lead wire holder has a first protrusion and a second protrusion on the side near the charging head. The first protrusion is arranged around the axis of the lead wire holder, and the second protrusion is arranged around the outer peripheral surface of the first protrusion. The second protrusion is spaced apart from the first protrusion so that the mounting groove is formed between the second protrusion and the first protrusion.

[0008] In one possible implementation, the second protrusion has a first connection hole, and the charging head has a second connection hole at one end near the wire seat. The charging gun also includes a first fastener, which passes through the first connection hole and the second connection hole to fix the wire seat and the charging head.

[0009] In one possible implementation, the first protrusion has a wire-passing hole through which the connecting wire passes.

[0010] In one possible implementation, the charging gun further includes a light-emitting wire, one end of which is electrically connected to the power supply device, and the other end of which passes through the mounting cavity and is electrically connected to the light-emitting element.

[0011] In one possible implementation, the charging head is made of a semi-transparent material to guide the light emitted by the light-emitting element located within the housing to the periphery of the charging head.

[0012] In one possible implementation, the charging head is made of a transparent material, and the charging head contains scattering particles.

[0013] This application also provides a charging device, including a power supply device and the aforementioned charging gun, wherein the power supply device is configured to supply power to the charging gun.

[0014] In the charging gun of this application, the charging head is detachably connected to the housing, facilitating quick removal of the charging head from the housing for repair or replacement should it be damaged due to frequent plugging and unplugging. Furthermore, the light-emitting element is located inside the housing, utilizing the internal space to install it. Compared to placing the light-emitting element outside the housing, this avoids changes in the charging gun's shape or increased size due to the addition of the light-emitting element. Additionally, since the light-emitting element is mounted on the charging head, it can be removed and placed after detaching the charging head. Attached Figure Description

[0024] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 2 As shown, and in combination Figure 5 This embodiment provides a charging gun 100 for charging products that need to be charged. The products to be charged can be electric vehicles, electric bicycles, electric tricycles, or other products that require charging.

[0026] The charging gun 100 is used in conjunction with the power supply device 1. The power supply device 1 supplies power to the charging gun 100 through the connecting cable 30. After the charging gun 100 is connected to the product to be charged, it transmits current to the product to be charged, thereby charging the product. The power supply device 1 can be a charging pile, etc.

[0027] The charging gun 100 includes a housing 10, a charging head 20, and a light-emitting element 50.

[0028] The housing 10 has a mounting cavity 13 for the connecting wire 30 to pass through. The connecting wire 30 is a cable or other wire that can transmit current. One end of the connecting wire 30 passes through the mounting cavity 13 and is electrically connected to the charging head 20. The other end of the connecting wire 30 can be directly fixed to the power supply device 1 and electrically connected to the power supply device 1, so as to realize the fixed design of the charging gun 100 and the power supply device 1.

[0029] It is understood that in other embodiments, the connecting cable 30 can be plugged into the power supply device 1 through a plug structure, thereby realizing a separate design between the charging gun 100 and the power supply device 1.

[0030] The charging head 20 is detachably connected to one end of the housing 10. The charging head 20 is used to connect with the product to be charged, thereby enabling charging of the product via the connecting cable 30 and the charging head 20. A light-emitting element 50 is connected to the charging head 20 and is located within the mounting cavity 13, allowing the light-emitting element 50 to be concealed within the housing 10 and avoid affecting the appearance of the charging gun 100. The charging head 20 is configured to guide the light emitted by the light-emitting element 50 to the outside of the charging head 20, enabling the light-emitting element 50 located within the mounting cavity 13 to smoothly transmit light to the outside of the housing 10, thereby achieving an illumination function and facilitating quick connection between the charging head 20 and the product to be charged.

[0031] Thus, in the charging gun 100 of this application, the charging head 20 is detachably connected to the housing 10, facilitating quick removal of the charging head 20 from the housing 10 for repair or replacement should it be damaged due to frequent plugging and unplugging. Furthermore, the light-emitting element 50 is located inside the housing 10, utilizing the internal space of the housing 10 for its installation. Compared to placing the light-emitting element 50 outside the housing 10, this avoids changes in the shape or increased size of the charging gun 100 due to the addition of the light-emitting element 50. Simultaneously, since the light-emitting element 50 is mounted on the charging head 20, it can be removed and placed after the charging head 20 is detached.

[0032] Please combine Figures 2 to 4 In one embodiment, the housing 10 has a hollow interior and is open at both ends. The housing 10 includes a first housing portion 11 and a second housing portion 12. A connecting wire 30 extends from one end of the first housing portion 11 into the mounting cavity 13, and the second housing portion 12 is integrally formed and connected to the other end of the first housing portion 11. The first housing portion 11 and the second housing portion 12 are inclined to facilitate the user's grip on the first housing portion 11.

[0033] In this embodiment, the second shell portion 12 is cylindrical in shape, and the extension direction of the first shell portion 11 is set at an angle to the extension direction of the second shell portion 12, and the angle is greater than 90°.

[0034] It is understood that in other embodiments, the second shell portion 12 may also be a columnar structure with a rectangular or elliptical cross-section.

[0035] In this embodiment, a button structure 14 is provided on the outer peripheral surface of the first housing 11, and a circuit board (not shown in the figure) and other structures are provided in the mounting cavity 13. The electronic components on the circuit board can receive signal commands from the button structure 14, thereby controlling the charging gun 100 to perform corresponding operations (such as starting or stopping the charging gun 100 or selecting the working state). It is worth noting that the specific control method of the button structure 14 of the charging gun 100 can be designed by those skilled in the art based on existing technology.

[0036] In one embodiment, the charging head 20 is detachably connected to the end of the second housing 12 away from the first housing 11. The charging head 20 includes a first region 21 and a second region 22. The first region 21 and the second region 22 are coaxially arranged, and their extending directions are both parallel to the extending direction of the second housing 12. The second region 22 is integrally formed and connected to the surface of the first region 21 near the second housing 12.

[0037] The second section 22 is housed within the mounting cavity 13 and is detachably connected to the housing 10. When the second section 22 is housed within the mounting cavity 13, its outer peripheral surface abuts against the inner peripheral surface of the second housing 12, and the end face of the first section 21 near the second section 22 abuts against the end face of the second housing 12 away from the first housing 11, thereby limiting the second housing 12's position on the charging head 20. Furthermore, the second section 22 and the second housing 12 are sealed together to ensure a tight seal during connection, ensuring that the light-emitting element 50 located within the housing 10 is in a sealed environment. This prevents liquids or other substances outside the housing 10 or the charging head 20 from entering the mounting cavity 13 and affecting the operation of the light-emitting element 50, thus improving the waterproof capability of the charging gun 100.

[0038] Specifically, the shape of the first section 21 is adapted to the shape of the second shell section 12 to ensure the aesthetic appearance of the charging gun 100. A sealing structure such as a sealing ring can be provided between the outer peripheral surface of the second section 22 and the inner peripheral surface of the second shell section 12 to prevent rainwater from entering the mounting cavity 13.

[0039] In this embodiment, a third connecting hole 220 is provided on the outer peripheral surface of the second region 22. There are multiple third connecting holes 220, which are evenly distributed around the axis of the second region 22 to improve the stability of the second region 22 when connected to the outer shell. The number of third connecting holes 220 can be two, three, four, etc.

[0040] The outer peripheral surface of the second shell 12 is provided with a fourth connecting hole 120. The number of fourth connecting holes 120 is the same as the number of third connecting holes 220, and the multiple fourth connecting holes 120 are correspondingly arranged with the multiple third connecting holes 220.

[0041] The charging gun 100 also includes second fasteners 90, the number of which is the same as the number of third connecting holes 220. Each second fastener 90 passes through a third connecting hole 220 and a corresponding fourth connecting hole 120, thereby securing the second section 22 to the second housing section 12. The second fasteners 90 are components such as countersunk screws.

[0042] It is understood that in other embodiments, the second region 22 and the second shell 12 may also be fixed by means of snap-fit ​​or adhesive bonding.

[0043] Please combine Figures 2 to 4 In one embodiment, the charging gun 100 further includes a wire holder 40 through which the connecting wire 30 passes to guide the layout of the connecting wire 30 and prevent the connecting wire 30 from intertwining.

[0044] The lead connector 40 is detachably connected to the end of the charging head 20 near the housing 10, and a mounting groove 44 is provided on the side of the lead connector 40 near the charging head 20. The light-emitting element 50 is housed in the mounting groove 44 and faces the charging head 20. Thus, by mounting the light-emitting element 50 on the lead connector 40 and detachably connecting the lead connector 40 to the charging head 20, when it is necessary to remove or install the light-emitting element 50, the charging head 20 is removed from the housing 10, and then the lead connector 40 is removed from the charging head 20 before the light-emitting element 50 can be installed or removed. Furthermore, this installation method allows the light-emitting element 50, the lead connector 40, and the charging head 20 to be independently configured, so that if any one of the three components is damaged, the damaged component can be replaced individually.

[0045] In this embodiment, the lead wire holder 40 has a first protrusion 41 and a second protrusion 42 protruding on the side near the charging head 20. The first protrusion 41 is annular in shape and is arranged around the axis of the lead wire holder 40. The second protrusion 42 is arranged around the outer peripheral surface of the first protrusion 41, and the second protrusion 42 is spaced apart from the first protrusion 41 so that a mounting groove 44 is formed between the second protrusion 42 and the first protrusion 41.

[0046] The light-emitting element 50 is fixed in the mounting groove 44 by snap-fit ​​or adhesive bonding. The wire connector 40 can be directly used as the mounting structure for the light-emitting element 50, eliminating the need for additional mounting structures. Furthermore, directly mounting the light-emitting element 50 onto the wire connector 40 avoids the need for additional mounting structures on the charging head 20 or housing 10, which would affect their structural integrity and necessitate additional molds to manufacture compatible charging heads 20 or housings 10, thus increasing production costs.

[0047] In particular, the light-emitting surface of the light-emitting element 50, the end face of the first protrusion 41 away from the wire seat 40, and the end face of the first protrusion 41 away from the wire seat 40 are coplanar, so that the light-emitting element 50 can radiate more light onto the charging head 20.

[0048] In this embodiment, the light-emitting element 50 is an LED strip or LED bead, which emits light towards the charging head 20. The charging head 20 is made of a semi-transparent material so that the light emitted by the light-emitting element 50 can pass through the charging head 20 and be projected to its surroundings, thereby achieving the illumination function. The semi-transparent material of the charging head 20 also allows the light emitted by the light-emitting element 50 to be scattered, making the light softer and creating a diffused light effect.

[0049] It is understood that in other embodiments, the charging head 20 may also be made of a transparent material and scattering particles may be added inside the charging head 20, so that the entire charging head 20 can be used as a light source, making it easy for users to see the position of the charging head 20 directly and clearly.

[0050] Specifically, the scattering particles are materials with high scattering capabilities. For example, the scattering particles are materials such as silicon dioxide. During the manufacturing of the charging head 20, the scattering particles are incorporated into the raw materials of the charging head 20 to ensure that the scattering particles are evenly distributed throughout the entire charging head 20. The scattering particles can disperse the light entering the charging head 20, thereby expanding the illumination range of the light-emitting element 50, so that the charging head 20 can function as a light source throughout.

[0051] In this embodiment, the second protrusion 42 has a first connecting hole 420, and the charging head 20 has a second connecting hole 221 at the end near the lead wire seat 40. The extending directions of the first connecting hole 420 and the second connecting hole 221 are parallel to the direction of the axis of the charging head 20. The first connecting hole 420 passes through the second protrusion 42, and the second connecting hole 221 extends inward from the surface of the second region 22 away from the first region 21.

[0052] The charging gun 100 also includes a first fastener 80, which passes through the first connection hole 420 and the second connection hole 221 to fix the wire seat 40 and the charging head 20.

[0053] The number of first connecting holes 420 is multiple, and the multiple first connecting holes 420 are equally spaced around the axis of the lead wire seat 40. The number of second connecting holes 221 is the same as that of the first connecting holes 420, and they are arranged corresponding to the first connecting holes 420. The number of first connecting holes 420 is two, three, etc., to improve the tightness of the connection between the lead wire seat 40 and the charging head 20, thereby pressing the lead wire seat 40 against the surface of the second region 22 away from the first region 21, so that the first protrusion 41 and the second protrusion 42 are both pressed against the surface of the second region 22 away from the first region 21, ensuring the sealing of the mounting groove 44 and preventing water or moisture from entering the mounting groove 44 and affecting the use of the light-emitting element 50.

[0054] Specifically, the lead wire holder 40 can be made of a material with a certain degree of elasticity, such as rubber, so that when the lead wire holder 40 is pressed against the charging head 20, it can undergo a certain elastic deformation to seal the contact surface between the first protrusion 41 and the second protrusion 42 and the second region 22, further ensuring the safety of the light-emitting element 50 in use. In addition, the elasticity of the lead wire holder 40 also makes it easy to directly hold the light-emitting element 50 in the mounting groove 44, which not only facilitates the placement and removal of the light-emitting element 50, but also avoids the need to use a mounting structure to install the light-emitting element 50.

[0055] Please combine Figures 2 to 4 In one embodiment, the first protrusion 41 has a wire-passing hole 43, which extends from the surface of the first protrusion 41 near the charging head 20 and passes through the first protrusion 41 and the lead wire seat 40. The wire-passing hole 43 allows the connecting wire 30 to pass through, and after passing through the wire-passing hole 43, the connecting wire 30 connects with the charging head 20 to form a current channel.

[0056] The connecting wires 30 include ground wires, neutral wires, live wires, signal wires, and other types of wires. There are multiple wire through holes 43, the same number as the number of connecting wires 30, so that different connecting wires 30 can pass through different wire through holes 43, thereby preventing the connecting wires 30 from getting tangled together.

[0057] Furthermore, the charging gun 100 also includes a light-emitting connector 70. One end of the light-emitting connector 70 is electrically connected to the power supply device 1, and the other end of the light-emitting connector 70 passes through the mounting cavity 13 and is electrically connected to the light-emitting element 50, so that the light-emitting element 50 is also powered by the power supply device 1, avoiding the need to set a separate power supply on the charging gun 100 to power the light-emitting element 50. In addition, since the light-emitting element 50 is mounted on the wire connector 40, when the connecting wire 30 is pulled to pass through the wire connector 40, the light-emitting connector 70 can be simultaneously pulled to the wire connector 40 to be electrically connected to the light-emitting element 50, thus eliminating the need to design an additional wiring method for the light-emitting connector 70, which simplifies the wiring and installation of the light-emitting element 50.

[0058] A wire-passing hole 440 is provided on the surface of the wire holder 40 away from the charging head 20. The wire-passing hole 440 extends parallel to the axis of the wire holder 40. The wire-passing hole 440 connects to the mounting groove 44, so that one end of the light-emitting wire 70 can be passed through the wire-passing hole 440 and extended into the mounting groove 44. The wire-passing hole 440 provided in the wire holder 40 can guide the layout of the light-emitting wire 70 and prevent the light-emitting wire 70 from getting tangled with the connecting wire 30.

[0059] Please combine Figures 2 to 4 In one embodiment, a receiving groove 23 is provided on the side of the second region 22 away from the first region 21. The extending direction of the receiving groove 23 is parallel to the extending direction of the wire hole 43, and the number of receiving grooves 23 is the same as the number of wire holes 43.

[0060] The charging gun 100 also includes terminals 60, the number of which is the same as the number of receiving slots 23. Each receiving slot 23 houses one terminal 60. One end of the connecting wire 30 passes through the wire hole 43 and extends into the receiving slot 23, where it is electrically connected to the terminal 60. The end of the terminal 60 furthest from the connecting wire 30 can be connected to the product to be charged to form a current path, thereby establishing a current path between the power supply device 1 and the product to be charged through the connecting wire 30 and the terminal 60 of the charging gun 100.

[0061] like Figure 5 As shown, this application embodiment also provides a charging device 200, including the aforementioned power supply device 1 and the aforementioned charging gun 100. The power supply device 1 is configured to supply power to the charging gun 100. The charging gun 100 can be directly fixed to the power supply device 1 via a connecting cable 30. Alternatively, the charging gun 100 can be plugged into the power supply device 1 by providing a plug on the connecting cable 30, thereby enabling the charging gun 100 to be used with different power supply devices 1.

[0062] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
