Description

Technical Field

[0001] The present application relates to the technical field of new energy equipment, and in particular to a wiring shell of a new energy charging equipment. Background Art

[0002] New energy vehicles have begun to appear in people's lives in large numbers, and along with them comes the problem of charging new energy vehicles, which has gradually emerged.

[0003] When charging new energy vehicles, you need to use new energy charging equipment, which includes a charging gun. Use the charging gun to connect the power cord and connect it to the charging socket on the new energy vehicle to achieve charging.

[0004] However, a general charging gun has a wiring shell on its outer surface, which provides insulation and safe holding. When the charging gun is plugged in and unplugged from the charging socket using the wiring shell, the charging gun will heat up, causing a large amount of heat to be generated on the surface of the wiring shell of the charging gun, which can easily cause damage to the charging module and easily cause burns to the user when the user touches the wiring shell, affecting safety. Summary of the invention

[0005] In order to improve the above-mentioned problems, the present application provides a wiring shell for a new energy charging device.

[0007] By adopting the above technical solution, the fixed tube is installed on the inner wall of the holding tube, and there is a partition cavity between the fixed tube and the holding tube. The fixed tube and the holding tube form a double-layer structure, which is connected by the partition cavity in the middle, and the power line is routed through the fixed tube and does not touch the holding tube. When the power line generates heat, the fixed tube contacts the heat, and is separated from the holding tube by the partition cavity, which reduces the situation where the heat is directly transferred to the holding tube, so that the surface temperature of the holding tube is reduced, thereby avoiding the situation where the user is burned when touching the wiring shell. Optionally, it also includes a holding piece and an elastic piece; a pressing port is provided on the holding tube, and the pressing port is connected to the partition cavity; the holding piece is slidably connected to the pressing port and extends into the partition cavity through the pressing port; the elastic piece is installed on the outer wall of the fixed tube, and is located in the partition cavity and connected to the holding piece, and applies elastic force to the holding piece.

[0008] By adopting the above technical solution, when the holding piece is held, it is pushed outward by the elastic force of the elastic piece, so that the holding piece only contacts the wall surface of the pressing port of the holding tube and the elastic piece, and cannot transfer too much heat. Therefore, the holding piece can be exposed to less heat, so that the user can be exposed to less heat when holding the holding piece, providing a safer and more comfortable use experience.

[0009] Optionally, two pressing openings are symmetrically provided on the holding tube along the axis, and the holding piece is provided in each pressing opening.

[0012] By adopting the above technical solution, the guide part is used to reduce the heat contact and transfer to the holding piece, and the pressing movement of the holding piece is made more stable through the guiding effect of the guide groove and the guide protrusion.

[0013] Optionally, the opening path of the guide groove is I-shaped and is divided into an upper section and a lower section; when the guide protrusion moves along the I-shaped path, the vertical groove of the guide groove is used for the guide protrusion to switch and move to the upper section or the lower section, so that the guide protrusion is stuck in the horizontal groove of the upper section or the lower section.

[0014] By adopting the above technical solution, when the guide protrusion is inserted into the upper section or the lower section, an adaptation effect can be achieved. For example, some users have larger palms and can insert them into the upper section when holding the grip to make the grip more comfortable to hold. Some users have smaller palms and can insert them into the lower section to allow the grip to extend further into the spacing groove, so that users with smaller palms can also get a comfortable holding experience.

[0016] By adopting the above technical solution, the elastic force of the elastic member is applied to the holding member, and the clamping member is driven to rise through the connecting member. The clamping member extends out of the clamping mouth and can be clamped into the clamping groove of the snap block. During the charging process, the wiring shell can be used to securely connect the charging socket and the power plug to avoid disconnection due to force.

[0017] Optionally, at least two clamping openings are provided, and the number of the corresponding connecting members is the same as the number of the clamping members.

[0019] Optionally, the clamping member is provided with an inclined surface, and the inclined surface faces the direction of the holding member.

[0020] By adopting the above technical solution, when the guide protrusion moves along the I-shaped path, the inclined surface of the clamping piece can abut against the clamping opening and enter the spacing cavity along the inclined surface, so that the movement of the clamping piece is smoother.

[0021] Optionally, the holding member is divided into a sliding portion and a holding portion, the guide protrusion is located on the sliding portion, and the holding portion provides a holding fulcrum; the holding portion and the sliding portion are detachably connected.

[0022] By adopting the above technical solution and utilizing the split gripping piece, the gripping part can be disassembled, replaced or repaired when it is damaged or dirty, thereby increasing the service life.

[0023] Optionally, a temperature detection component is also provided on the holding tube.

[0024] By adopting the above technical solution, the temperature detection element can be used to provide real-time temperature detection and warning effect when the wiring shell generates heat.

The fixed tube and the holding tube form a double-layer structure, which is connected by the spacer cavity in the middle. The power line is routed inside the fixed tube and does not touch the holding tube. When the power line generates heat, the fixed tube contacts the heat, and the spacer cavity is used to separate the fixed tube from the holding tube, which reduces the direct transfer of heat to the holding tube, reduces the surface temperature of the holding tube, and avoids the user from being burned when touching the wiring shell. 2. When the grip is held, it is pushed outward by the elastic force of the elastic member, so that the grip only contacts the wall surface of the pressing opening of the grip tube and the elastic member, and cannot transfer too much heat. Therefore, the grip is exposed to less heat, so that the user is exposed to less heat when holding the grip, providing a safer and more comfortable use experience; 3. Use the guide part to reduce the heat contact and transfer to the gripping piece, and through the guiding effect of the guide groove and the guide protrusion, the pressing movement of the gripping piece is more stable; 4. When the guide protrusion is inserted into the upper section or the lower section, it can achieve an adaptation effect. For example, some users have larger palms and can insert them into the upper section when holding the grip to make the grip more comfortable. Some users have smaller palms and can insert them into the lower section to allow the grip to extend further into the spacing groove, so that users with smaller palms can also get a comfortable holding experience.

[0031] Throughout the specification, when a device is said to be "connected" to another device, this includes not only the case of "direct connection" but also the case of "indirect connection" by placing other elements therebetween. In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0032] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0033] The embodiment of the present application discloses a wiring shell for a new energy charging device.

[0034] A wiring shell for a new energy charging device, wherein the wiring shell has a channel for routing the power line. Figure 1 and Figure 2 As shown, it includes a power connection piece 1, a holding tube 2, a fixing tube 3 and a wiring piece 4; the power connection piece 1 is used to connect to the charging socket 9, and is divided into two sections, one section is a docking ring 11, and the other section is a compression ring 12. The diameter of the docking ring 11 is larger than the compression ring 12. The power connection piece 1 is a contact end connected to the new energy vehicle. The power cord is provided with a power connection plug at the docking ring 11. The power connection plug is fixedly connected to the docking ring 11. The diameter of the docking ring 11 is larger than the compression ring 12, so that when it is abutted and inserted into the charging socket 9, the receiving area can be expanded to avoid arcing, leakage and the like. In addition, the power connection piece 1 is made of insulating material as a whole to ensure circuit safety.

[0035] One end of the holding tube 2 is connected to the compression ring 12, and the diameter of the holding tube 2 is larger than the compression ring 12, and a truncated cone-shaped chamfered structure is formed at the connection with the compression ring 12. The chamfered structure can make the connection between the internal power cord and the compression ring 12 more stable and tight, reducing the possibility of the power cord loosening.

[0036] The terminal block 4 is connected to the end of the holding tube 2 away from the compression ring 12. The terminal block 4 is used to wrap the power cord to provide protection and safety for the power cord. It can be made of soft insulating materials such as rubber or plastic, has a certain degree of ductility, and is easy to bend or stretch.

[0037] The fixed tube 3 is installed on the inner wall of the holding tube 2, and there is a partition cavity 21 between the fixed tube 3 and the holding tube 2. The fixed tube 3 and the holding tube 2 form a double-layer structure, which is connected by the partition cavity 21 in the middle, and the power cord is routed through the fixed tube 3 and does not touch the holding tube 2. When the power cord generates heat, the fixed tube 3 contacts the heat, while being separated from the holding tube 2 by the partition cavity 21, thereby reducing the direct transfer of heat to the holding tube 2, reducing the surface temperature of the holding tube 2, and preventing the user from being scalded when touching the wiring shell.

[0038] For further reference, Figure 3 As shown, it also includes a gripping piece 5 and an elastic piece 6; a pressing port 22 is provided on the gripping tube 2, and the pressing port 22 is communicated with the partition cavity 21. The gripping piece 5 is slidably connected with the pressing port 22 and extends into the partition cavity 21 through the pressing port 22. The gripping piece 5 can adopt a handle, and a gripping groove for finger gripping can be provided on the surface of the handle to fit the pressing and receiving of the fingers. The gripping piece 5 can be inserted into the partition cavity 21 along the pressing port 22, and can also be taken out from the partition cavity 21 through the pressing port 22.

[0039] The elastic member 6 is installed on the outer wall of the fixed tube 3, and is located in the partition cavity 21 and connected to the holding member 5, and applies elastic force to the holding member 5, so that when the holding member 5 is held, it is pushed outward by the elastic force of the elastic member 6, so that the holding member 5 only contacts the wall surface of the pressing port 22 of the holding tube 2 and the elastic member 6. The elastic member 6 can be a spring. The contact area of ​​the spring is small and cannot transfer too much heat. Therefore, the holding member 5 can be exposed to less heat, so that the user can be exposed to less heat when holding the holding member 5, providing a safer and more comfortable use experience.

[0040] The gripping member 5 may also be wrapped with a rubber layer to improve insulation and further increase safety.

[0041] Among them, the installation position of the holding member 5 can also provide a more accurate position for plugging in and charging. For example, the charging socket 9 and the hole of the power plug need to be docked for plugging in and charging. The installation position of the holding member 5 can intuitively determine the alignment position of the charging socket 9 and the hole of the power plug, without the need for observation and calibration, thereby improving usage efficiency.

[0042] Furthermore, two pressing holes 22 are symmetrically provided on the holding tube 2 with an axis, and a holding piece 5 is provided in each pressing hole 22. After the two pressing holes 22 are provided, the positions of the holding pieces 5 are relatively set, which is more in line with the holding method of the human hand. For example, the upper holding piece 5 is in line with the pressing and fitting method of the thumb, and the lower holding piece 5 is more in line with the pressing and fitting method of the other four fingers. The two can directly provide a pressing and clamping wiring shell, providing a more comfortable use experience, and at the same time, the fingers are further reduced from touching the holding tube 2.

[0043] In some embodiments, reference Figure 4 As shown, a guide portion 23 is further provided in the partition cavity 21, and the guide portion 23 is located below the pressing port 22. The guide portion 23 is connected to the inner wall of the holding tube 2 and extends toward the outer wall of the fixed tube 3, but is not connected to the outer wall of the fixed tube 3. The guide portion 23 can adopt a guide plate or a guide rail. The guide portion 23 is installed on the inner wall of the holding tube 2 and does not contact the outer wall of the fixed tube 3. The main purpose is to avoid the heat generated by the fixed tube 3 from being transferred to the guide portion 23 through contact, and to reduce the heat conduction effect by utilizing the non-direct contact installation situation.

[0044] The guide portion 23 is provided with a guide groove 231, and the holding piece 5 is provided with a guide protrusion 51, and is slidably connected to the guide groove 231 through the guide protrusion 51. By utilizing the guiding effect of the guide protrusion 51 and the guide groove 231, the holding piece 5 is fixed along the lifting path of the pressing port 22 without deviation, and the stability during use is better.

[0045] Specifically, the guide portion 23 is utilized to reduce the heat contact transfer to the holding member 5, and the pressing movement of the holding member 5 is made more stable through the guiding effect of the guide groove 231 and the guide protrusion 51.

[0046] For further reference, Figure 4 As shown, the opening path of the groove is in the shape of an I-shape, which is divided into an upper section and a lower section, that is, two horizontal upper and lower moving paths of the I-shape. When the guide protrusion 51 moves along the I-shaped path, the vertical groove of the guide groove 231 is used to switch the guide protrusion 51 to move to the upper section or the lower section, so that the guide protrusion 51 is stuck in the horizontal groove of the upper section or the lower section.

[0047] When the guide protrusion 51 is inserted into the upper section or the lower section, an adaptation effect can be achieved. For example, some users have larger palms and can insert them into the upper section when holding the grip 5 to make it more comfortable to hold. Some users have smaller palms and can insert them into the lower section to allow the grip 5 to extend further into the spacing groove, so that users with smaller palms can also get a comfortable holding experience.

[0048] At the same time, when the guide protrusion 51 is stuck in the upper section or the lower section, the user cannot continue to press, so that the position of the grip 5 is fixed. This method is also suitable for users who are not accustomed to the elastic grip of the elastic member 6. After the grip 5 is fixed, the grip 5 can be directly gripped. The elastic force of the elastic member 6 only provides a reset effect when it is located at the vertical groove.

[0049] In some embodiments, reference Figure 5 and Figure 6 As shown, when the charging socket 9 is charged with the power plug, in order to avoid damage to the charging socket 9 and the power plug due to violent pulling, a snap-fit ​​block 91 can be provided on the charging socket 9, and a snap-fit ​​groove 92 is provided in the snap-fit ​​block 91, and a clamping opening 111 is provided on the docking ring 11, and the clamping opening 111 is connected to the spacing cavity 21. The holding member 5 is also provided with a connecting member 7, and the connecting member 7 extends along the spacing cavity 21 to the clamping opening 111. The connecting member 7 can adopt a connecting rod. A clamping member 8 is also provided on the connecting member 7, and the clamping member 8 extends outward through the clamping opening 111. The clamping member 8 can adopt a clamping block. After the clamping block extends out of the clamping opening 111, it can be inserted into the clamping groove 92 of the clamping block 91 for clamping.

[0050] Specifically, the holding member 5 is acted upon by the elastic force of the elastic member 6 and moves along the guide groove 231 through the guide protrusion 51. During the movement, the snap-fit ​​member 8 is driven to rise through the connecting member 7, and the snap-fit ​​member 8 extends out of the clamping opening 111 and can be snapped into the snap-fit ​​groove 92 of the snap-fit ​​block 91. This means that during the charging process, the charging socket 9 and the power plug can be fastened together using the wiring shell to avoid disconnection due to force. After the battery is fully charged, the user presses the holding member 5 to move the holding member 5 along the guide groove 231 toward the partition cavity 21, and uses the connecting member 7 to simultaneously drive the snap-fit ​​member 8 to move toward the partition cavity 21, so that the snap-fit ​​member 8 is disengaged from the snap-fit ​​groove 92 and enters the partition cavity 21, so that the wiring shell will not be fixed by the snap-fit ​​groove 92 of the external snap-fit ​​block 91, and the wiring shell and the power plug can be separated from the charging socket 9.

[0051] Among them, if some old-style charging sockets 9 are not provided with the snap-fit ​​block 91 or the snap-fit ​​groove 92 , the extension and retraction of the clamping member 8 are both located at the docking ring 11 , so it will not affect the normal charging process.

[0052] Furthermore, there are at least two clamping openings 111, and the number of corresponding connecting members 7 and clamping members 8 is the same. The at least two clamping openings 111 and the connecting members 7 and clamping members 8 can cooperate with the external snap-fit ​​block 91 to form multiple clamping points, further improving the tightness of the connection.

[0053] Furthermore, the clamping member 8 is provided with an inclined surface, which faces the direction of the holding member 5, so that when the guide protrusion 51 moves along the I-shaped path, the inclined surface of the clamping member 8 can abut against the clamping mouth 111 and enter the partition cavity 21 along the inclined surface, so that the movement of the clamping member 8 is smoother.

[0054] Further, refer to Figure 4 As shown, the holding member 5 is divided into a sliding portion 52 and a holding portion 53, the guide protrusion 51 is located on the sliding portion 52, and the holding portion 53 provides a holding fulcrum. The sliding portion 52 can adopt a sliding block, and the holding portion 53 can adopt a holding frame. The style of the holding frame is the same as the style of a groove formed by hand grasping. The holding portion 53 and the sliding portion 52 are detachably connected, and the detachable connection can be a socket connection, such as a socket slot is provided on the sliding portion 52, and the socket slot is open at one end, and the socket slot can be a T-slot or an I-slot. A socket protrusion is provided at the bottom of the holding portion 53, and the style of the socket protrusion matches the style of the T-slot or the I-slot, so that the holding portion 53 can be inserted into it along the socket slot to achieve installation. When disassembly is required, it can be pulled out along the notch of the socket slot.

[0055] The socket slot requires the sliding portion 52 to be located outside the pressing opening 22 when receiving the elastic force of the elastic member 6, so as to ensure that the gripping portion 53 can be socketed.

[0056] The split gripping member 5 allows the gripping portion 53 to be disassembled, replaced or repaired when it is damaged or dirty, thereby increasing the service life.

[0057] In some embodiments, reference Figure 4 As shown, a temperature detection component 24 is also provided on the holding tube 2. The temperature detection component 24 may include a temperature sensor, a display screen or a display light. The temperature sensor may be installed in the partition cavity 21 and contact the inner wall of the holding tube 2. When the charging socket 9 is connected to the power plug, the temperature of the holding tube 2 can be detected at all times and displayed through the display screen or the display light. When a display screen is used, the real-time temperature can be displayed at all times. When a display light is used, the color or flashing condition of the display light can be set. For example, when the temperature of the holding tube 2 is above 40 degrees, the display light is always on in red, and when the temperature is above 50 degrees, it flashes in red. The intuitive display effect of the display screen or the display light provides a warning effect for the user, which can further prevent the user from being scalded.

[0058] Specifically, the temperature detection element 24 can provide real-time temperature detection and a warning effect when the wiring housing generates heat.

[0059] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
