Description

Technical Field

[0001] This invention relates to the field of charging equipment technology, and more specifically, to a charging device. Background Technology

[0002] In modern society, more and more people are choosing green travel, and new energy vehicles are gradually becoming more widespread. These vehicles primarily rely on electric power, and the quantity and quality of charging equipment in a modern city significantly impacts their usage. Charging equipment is also an integral part of future urban and smart grid construction. In enhancing product competitiveness and user experience, product appearance also plays a crucial role. Currently, charging equipment on the market typically features a movable hook on the charging gun head, and a gun head storage cavity on the charging pile body or outside the pile, with a fixed buckle on the storage cavity. When not charging, the charging gun is inserted into the storage cavity. This existing structure causes the charging gun body and cable to be under stress due to their own weight, making them prone to aging and damage. Furthermore, the charging gun is exposed outside the charging equipment when stored, making it susceptible to damage and affecting aesthetics, resulting in a poor user experience.

[0003] As can be seen from the above, the charging gun of the charging device is easily damaged in the existing technology. Summary of the Invention

[0006] Furthermore, the charging gun assembly also includes a gun holder, which is vertically arranged and has a receiving groove with an opening facing the side, the receiving groove being used to receive at least a portion of the charging gun.

[0007] Furthermore, the charging gun assembly also includes: a driving component, which is disposed on the gun holder; a gear, in which a rack is disposed inside the housing, the rack is vertically disposed and meshes with the gear, and the driving component is driven to drive the charging gun assembly to move up and down.

[0008] Furthermore, the gun mount includes a base with an installation space. A first partition is provided in the installation space to divide the installation space into a first installation cavity and a second installation cavity. A drive unit is housed in the first installation cavity and mounted on the first partition. A gear is housed in the second installation cavity. The side wall of the base has a clearance notch communicating with the second installation cavity so that at least a portion of the gear extends out of the second installation cavity and meshes with the rack.

[0009] Furthermore, the rack is located on one side of the gun mount, and a guide wheel structure is provided on the side of the base away from the rack. The guide wheel structure includes a guide wheel and two fixing ears. The two fixing ears are spaced apart in the horizontal direction. The fixing ears have mounting holes. The two ends of the guide wheel extend into the mounting holes of the two fixing ears respectively, so that the guide wheel is rotatably connected to the base.

[0010] Furthermore, there are multiple guide wheel structures, which are spaced apart along the vertical direction.

[0011] Furthermore, there are two guide wheel structures, which are symmetrically arranged in the vertical direction with respect to the horizontal axis passing through the center of the gear.

[0012] Furthermore, a limit rib is provided at the opening, and the limit rib and the guide wheel structure limit stop.

[0013] Furthermore, the gun holder includes a base, a receiving section, and a limiting section connected in sequence from top to bottom. The receiving section has a receiving groove, and the limiting section has a limiting groove that is sequentially connected to the receiving groove. The limiting groove is used to receive at least another part of the charging gun, and a limiting member is provided at the limiting groove to limit and stop the charging gun.

[0014] Furthermore, the base protrudes from the opening of the receiving groove.

[0015] Furthermore, the charging device also includes a pressure cover, which is disposed on the front side of the charging gun assembly and connected to the housing. One of the pressure cover and the charging gun assembly or one of the housing and the charging gun assembly is provided with a first slide rail, which extends in a vertical direction. The other is provided with a corresponding first slide groove, and the first slide rail is accommodated in the first slide groove so that the charging gun assembly is slidably connected to the pressure cover or the housing.

[0016] Furthermore, one of the housing and the charging gun assembly is provided with a second slide groove that extends vertically, and the other is provided with a corresponding second slide rail that is accommodated within the second slide groove, so that the charging gun assembly and the housing are slidably connected.

[0017] Furthermore, the charging device also includes: a charging module electrically connected to the charging gun; a touch screen located on the front side of the housing; and a control module, with both the charging module and the touch screen electrically connected to the control module.

[0035] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0036] To address the problem of easily damaged charging guns in existing charging devices, this invention provides a charging device.

[0037] like Figures 1 to 7As shown, the charging device includes a housing 10 and a charging gun assembly. An opening 11 is provided at the bottom of the housing 10. The charging gun assembly is disposed within the housing 10 and includes a charging gun 20, which is vertically positioned with its tip pointing upwards. The charging gun assembly is vertically movably connected to the housing 10, allowing it to extend or retract from the opening 11.

[0038] By configuring the charging device, which includes a housing 10 and a charging gun assembly, an opening 11 is provided at the bottom of the housing 10. The charging gun assembly is located inside the housing 10 and includes a charging gun 20. The charging gun 20 is vertically positioned with its head facing upwards. The charging gun assembly is movably connected to the housing 10, allowing it to extend or retract from the opening 11. This vertical positioning of the charging gun 20 ensures that its body is essentially parallel to the charging cable, allowing the cable to hang naturally and preventing stress and aging damage. Furthermore, by movably connecting the charging gun assembly to the housing 10, the charging gun 20 extends from the bottom of the housing when needed and retracts into the housing 10 after use, preventing damage to the charging gun 20 when not in use and significantly extending its service life.

[0039] like Figures 3 to 8 As shown, the charging gun assembly also includes a gun holder 30. The gun holder 30 is vertically arranged and has a receiving groove 321 with an opening facing the side, the receiving groove 321 being used to receive at least a portion of the charging gun 20.

[0040] like Figures 3 to 7 As shown, the charging gun assembly also includes a drive unit 40 and a gear 50. The drive unit 40 is disposed on the gun holder 30. A rack 60 is disposed inside the housing 10. The rack 60 is vertically arranged and meshes with the gear 50. The drive unit 40 is driven by the gear 50 to drive the charging gun assembly to move up and down.

[0041] like Figure 6 and Figure 9 As shown, the gun mount 30 includes a base 31 with an installation space. A first partition 311 is provided within the installation space to divide it into a first installation cavity and a second installation cavity. A drive member 40 is housed in the first installation cavity and mounted on the first partition 311, while a gear 50 is housed in the second installation cavity. Specifically, the second installation cavity is located near the rear shell of the housing 10 relative to the first installation cavity, and a rack 60 is disposed on the rear shell. The sidewall of the base 31 has a clearance notch 38 communicating with the second installation cavity, allowing at least a portion of the gear 50 to extend out of the second installation cavity and engage with the rack 60.

[0042] In this embodiment, the driving component 40 is a motor, and the output shaft of the motor is horizontally arranged. A through hole is provided in the first partition 311, through which the output shaft of the motor passes and is connected and fixed to the gear 50 via a snap ring 120. Figure 5 As shown. The output shaft of the motor drives the gear 50 to rotate, which in turn drives the gun holder 30 and the charging gun 20 to move up and down in the vertical direction. It can be understood that since the gear 50 needs to mesh with the rack 60, the position of the gear 50 in the second mounting cavity is closer to one side of the rack 60, and the aforementioned clearance notch 38 is opened on this side. Correspondingly, the position of the motor in the first mounting cavity is also closer to one side of the rack 60.

[0043] like Figure 2 and Figure 6 As shown, the charging device also includes a pressure cover 80. The pressure cover 80 is disposed on the front side of the charging gun assembly and connected to the housing 10. The pressure cover 80 is provided with a first slide rail 81, which extends vertically. The charging gun assembly is correspondingly provided with a first slide groove 36, and the first slide rail 81 is accommodated within the first slide groove 36, so that the charging gun assembly is slidably connected to the pressure cover 80 or the housing 10. Specifically, since the base 31 protrudes forward, the first slide groove 36 is located on the base 31. Of course, it is also possible that the pressure cover 80 is provided with the first slide groove 36, and the charging gun assembly is correspondingly provided with the first slide rail 81, which can be selected according to actual needs. It can be understood that in this embodiment, the housing 10 and the charging gun assembly are vertically arranged, with the front side facing the user. Furthermore, one of the housing 10 and the charging gun assembly may be provided with a first slide rail 81, and the other may be provided with a corresponding first slide groove 36. That is, the charging device does not have a pressure cover 80, and the first slide rail 81 or the first slide groove 36 is directly provided on the front cover of the housing 10. The choice can be made according to actual needs.

[0044] like Figure 3 and Figure 6 As shown, the housing 10 is provided with a second sliding groove 14, which extends vertically. The charging gun assembly is correspondingly provided with a second sliding rail 37, which is housed within the second sliding groove 14, allowing for a slidable connection between the charging gun assembly and the housing 10. Specifically, the second sliding groove 14 is located on the rear shell of the housing 10, and the second sliding rail 37 is located at the rear end of the base 31. Alternatively, the housing 10 can be provided with the second sliding rail 37, and the charging gun assembly can be provided with the corresponding second sliding groove 14, depending on actual needs. By providing sliding groove and sliding rail structures on the front and rear sides of the charging gun assembly, the charging gun assembly can move more smoothly and stably up and down with the housing 10, avoiding misalignment that could affect normal use.

[0045] In this embodiment, there are multiple first slide rails 81 and multiple first slide grooves 36, each corresponding to the other and spaced apart in the horizontal direction. Correspondingly, there are also multiple second slide rails 37 and multiple second slide grooves 14, each corresponding to the other and spaced apart in the horizontal direction.

[0046] like Figure 3 , Figures 5 to 9 As shown, the rack 60 is located on one side of the gun mount 30, and a guide wheel structure is provided on the side of the base 31 away from the rack 60. That is, the guide wheel structure and the rack and pinion structure are located on opposite sides of the gun mount 30 along the vertical direction. The guide wheel structure includes a guide wheel 70 and two fixing ears 35, which are spaced apart horizontally. Each fixing ear 35 has a mounting hole, and both ends of the guide wheel 70 extend into the mounting holes of the two fixing ears 35, allowing the guide wheel 70 to be rotatably connected to the base 31. Specifically, the guide wheel 70 includes a body and a rotating shaft. The body is fitted onto the rotating shaft and rotates along the shaft, and both ends of the rotating shaft are connected to the two fixing ears 35.

[0047] Specifically, there are multiple guide wheel structures, which are spaced apart vertically. By using multiple guide wheel structures, a better guiding effect can be achieved, improving the movement stability of the charging gun assembly.

[0048] In this embodiment, there are two guide wheel structures, which are symmetrically arranged vertically with respect to the horizontal axis passing through the center of the gear 50, i.e., vertically symmetrically arranged. For example... Figure 7 As shown, by setting two guide wheel structures on the other side of the rack 60, the force-bearing points of the two guide wheel structures and the force-bearing points at the meshing point of the gear 50 and the rack 60 are arranged in an isosceles triangle, thereby reducing the radial force F of the gear 50. X The force is evenly decomposed into two horizontal forces F1 and F2, ensuring that the charging gun assembly does not tilt, jam, or produce noise during movement, while also effectively reducing the lateral friction between the two second slide rails 37.

[0049] like Figure 3 As shown, a limiting rib 15 is provided at the opening 11, and the limiting rib 15 and the guide wheel structure are limited and stopped. Specifically, when the charging gun assembly moves downward to the limit position, the guide wheel structure is limited and stopped by the limiting rib 15 to prevent the gear 50 and the rack 60 from disengaging.

[0050] like Figures 8 to 9As shown, the charging gun holder 30 includes a base 31, a receiving section 32, and a limiting section 33 connected sequentially from top to bottom. The receiving section 32 has a receiving groove 321, and the limiting section 33 has a limiting groove 331 that communicates sequentially with the receiving groove 321. The limiting groove 331 is used to receive at least another part of the charging gun 20. A limiting member 34 is provided at the limiting groove 331 to limit and stop the charging gun 20.

[0051] Specifically, in actual use, after the charging gun 20 enters the receiving groove 321, it slides downwards due to its own gravity. Part of it is contained within the receiving groove 321, and another part is contained within the limiting groove 331. The limiting member 34 at the limiting groove 331 limits and stops the charging gun 20. Specifically, the head and upper part of the charging gun 20 are located within the receiving groove 321, the upper middle part of the charging gun body is located within the limiting groove 331, and the lower half is exposed and suspended in the air from the gun holder 30. At this time, the charging gun body is roughly parallel to the bottom wall of the limiting groove 331 and the receiving groove 321, and the charging cable of the charging gun 20 falls naturally. This reduces the safety hazards such as aging and damage caused by the cable being under tension for a long time at the connection point with the charging gun body, and increases the service life of the cable.

[0052] In this embodiment, the limiting member 34 is a claw. Specifically, there are two claws, which are located on both sides of the limiting groove 331 and protrude from the opening of the limiting groove 331.

[0053] Specifically, the two claws move inward, forming a raised arc-shaped channel at the limiting groove 331. In this embodiment, the outer diameter of the charging gun 20 body, at least the portion located in the limiting groove 331, gradually decreases from top to bottom. Correspondingly, the cross-sectional area of ​​the limiting groove 331 gradually decreases in the direction away from the receiving section 32, so that the limiting groove 331 matches the portion of the charging gun 20 body located in the limiting groove 331, thereby achieving a good limiting effect.

[0054] In this embodiment, the claw can be made of a material with a certain degree of elasticity. Even if the charging gun 20 is pressed down along the gun holder 30 due to human error, the claw can expand slightly outward, reducing the breakage and damage of the limiting member 34 caused by multiple misoperations.

[0055] In an optional embodiment, the limiting member 34 is a clamp, one end of which is rotatably connected to one side of the limiting groove 331, and the other end is engaged with the other side of the limiting groove 331. Specifically, a positioning pin hole is provided on one side of the limiting groove 331, one end of the clamp is connected to one side of the limiting groove 331 through a positioning pin, a slot is provided on the other side of the limiting groove 331, and the other end of the clamp has a buckle, thereby achieving a locking engagement. In use, the charging gun 20 is first placed into the receiving groove 321, and then the clamp is rotated and fastened onto the limiting groove 331. The clamp's locking engagement with the slot on the other side of the limiting groove 331 achieves the clamp's limitation of the charging gun 20. Of course, a bolt and nut can also be used on the other side to achieve the connection and fixation of the clamp.

[0056] Specifically, the gun holder 30 consists of a receiving groove 321 and a limiting groove 331 from top to bottom. The bottom of the limiting groove 331 gradually approaches the limiting member 34 from a vertically downward position. Similarly, the body of the charging gun 20 is also provided with a certain arc section so that when the charging gun 20 slides down to the limiting member 34, it can be matched with the limiting groove 331.

[0057] In this embodiment, the base 31 protrudes from the opening of the receiving groove 321. That is, the base 31 extends forward in the horizontal direction, so that the base 31 can cover the entire receiving groove 321 and the entire gun head, preventing water or other contaminants from entering the gun head and causing damage to the charging gun 20.

[0058] In this embodiment, the charging gun 20 and the gun holder 30 are connected and fixed by magnetic attraction. Specifically, both the charging gun 20 and the gun holder 30 are provided with magnetic components. Since their magnetic properties are opposite, the charging gun 20 is fixed to the gun holder 30 based on the principle of attraction between opposite poles. Alternatively, one of the charging gun 20 and the gun holder 30 may have a magnetic component, while the other may have a magnetic conductor; the choice can be made according to actual needs.

[0059] like Figure 4 As shown, the charging gun 20 includes a button 21 and a hook 22, with the button 21 and hook 22 being drivenly connected. During use, pressing the button 21 unlocks the hook 22, allowing the entire gun head to enter the charging port of the device to be charged. Releasing the button 21 then engages the hook 22 with the charging port to lock the charging gun 20. After charging is complete, pressing the button 21 again unlocks the charging gun 20, allowing it to be removed.

[0060] like Figures 1 to 3As shown, the charging device also includes a charging module 90, a touch screen display 100, and a control module 110. The charging module 90 is electrically connected to the charging gun 20. The touch screen display 100 is located on the front side of the housing 10. Both the charging module 90 and the touch screen display 100 are electrically connected to the control module 110. Specifically, a cable hole 18 is also provided at the bottom of the housing 10, through which the charging cable of the charging gun 20 enters the housing 10 and connects to the charging module 90.

[0061] In this embodiment, the housing 10 includes a front cover and a rear cover, which together form an accommodating space. A touch display screen 100 is disposed on the front cover to display charging parameters, function menus, and allow the user to perform touch operations.

[0062] In this embodiment, the control module 110 includes an intelligent PCBA module and a display control function module. The charging module 90 is a PCBA charging module. The intelligent PCBA module controls the charging module 90, and the display control function module controls the touch screen 100. Furthermore, the drive component 40 is electrically connected to the intelligent PCBA module. When the charging gun assembly moves downwards until the guide wheel 70 abuts against the limiting rib 15 or moves upwards until the base 31 abuts against the second partition 16, the current of the drive component 40 increases. After detecting the increase in the current of the drive component 40, the intelligent PCBA module sends a stop command to the drive component 40 to stop its operation.

[0063] like Figures 2 to 3 As shown, the housing 10 has a first accommodating cavity 12 and a second accommodating cavity 13 that are isolated from each other. The charging module 90 and the control module 110 are housed in the first accommodating cavity 12, and the charging gun assembly is housed in the second accommodating cavity 13. Through the above arrangement, the charging devices and the charging gun assembly are electrically isolated to avoid mutual interference. Specifically, the housing 10 includes a second partition 16 and a third partition 17, which are perpendicular to each other and arranged in an L-shape or T-shape, thereby forming the second accommodating cavity 13 with the peripheral sidewall of the housing 10. The second partition 16 is arranged horizontally, and the third partition 17 is arranged vertically. The third partition 17 is also provided with a mounting post with a threaded hole. The corresponding vertical sidewall of the housing 10 is also provided with a mounting post so that the pressure cap 80 is installed in the second accommodating cavity 13 by screws.

[0064] In this embodiment, there is a first fitting gap between the guide wheel 70 and the third partition plate 17, a second fitting gap between the second slide rail 37 and the groove wall of the second slide groove 14, and an outlet gap between the bottom end of the gun holder 30 and the inner wall of the opening 11. The outlet gap is larger than the first fitting gap and also larger than the second fitting gap, so as to ensure that the charging gun assembly does not skew, jam, or cause noise during its up and down movement.

[0065] In this embodiment, the charging device is a charging pile.

[0066] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: By setting the charging device to include a housing 10 and a charging gun assembly, an opening 11 is provided at the bottom of the housing 10, the charging gun assembly is disposed inside the housing 10, the charging gun assembly includes a charging gun 20, the charging gun 20 is vertically arranged with the gun head facing upward, and the charging gun assembly is movably connected to the housing 10 vertically so that the charging gun assembly extends or retracts from the opening 11. In this way, the charging gun 20 is vertically arranged, so that the gun body of the charging gun 20 is basically parallel to the charging cable, and the charging cable can maintain a natural hanging state, avoiding stress and tension with the gun body, which would cause aging and damage. Furthermore, by setting the charging gun assembly to be movably connected to the housing 10 vertically, the charging gun 20 extends out of the housing from the bottom when it is needed and retracts into the housing 10 after use, avoiding damage to the charging gun 20 when it is not in use, and greatly improving the service life of the charging gun 20.
