[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1 Reference Figure 2 to Figure 17 , which is the first embodiment of the present invention, provides an electric vehicle wiring harness connector, which includes a protective component 200, a connecting component 300 and a main component 100. The three can cooperate to prevent the socket from being damaged during daily use and maintenance, and it can be automatically opened without manual operation. It will only be opened when a matching plug is inserted to prevent wrong insertion, improve operation accuracy and specifications, and reduce the risk of equipment damage caused by wrong insertion.

[0039] The protection assembly 200 includes a protection member 201, which includes a protection door 201a, a pulling frame 201b, a rotating rod 201c, a rotating shell 201d, a block 201e, a rotating disk 201f, a gear 201g, a rack 201h and a return spring 201i. The pulling frame 201b is hinged to one side of the protection door 201a, the rotating rod 201c is hinged to one end of the pulling frame 201b, and the rotating shell 201d is fixed to the rotating rod On one side of 201c, the block 201e is located in the rotating shell 201d, the rotating disk 201f is sleeved on the outside of the block 201e, the rotating disk 201f and the block 201e are hinged, the gear 201g is fixed to one side of the rotating disk 201f, the rack 201h is set on the top of the gear 201g, the rack 201h and the gear 201g are meshed, one end of the return spring 201i is fixed to the bottom of the block 201e, and the other end is fixed to the inner wall of the rotating disk 201f.

[0040] When the socket 101 is not in use, the protective door 201a can be used to protect the socket 101 to prevent dust and debris from entering the socket 101. When the plug 102 and the socket 101 need to be connected, the plug 102 is moved close to one side of the socket 101 to squeeze the rack 201h to make it move, and the movement of the rack 201h can drive the gear 201g to rotate. At this time, the rotation of the gear 201g can drive the rotating disk 201f to rotate, and the rotation of the rotating disk 201f can drive the block 201e to move. An inclined groove corresponding to the block 201e is provided in the rotating shell 201d. The rotating shell 201d can be driven to rotate by squeezing the inclined groove by the block 201e, and the rotating shell 201d can be driven to rotate by the rotation of the rotating shell 201d. The rotating rod 201c can be driven to rotate, and the rotation of the rotating rod 201c can drive the pulling frame 201b to move. The movement of the pulling frame 201b can drive the protective When the plug 102 is separated from the socket 101, the rack 201h is released, and the rack 201h returns to its original position. When the rack 201h returns to its original position, the rotating disk 201f drives the card block 201e to reverse, and then the inclined groove on the rotating shell 201d squeezes the card block 201e, so that the card block 201e moves into the rotating disk 201f. When the card block 201e moves, it can exert an extrusion force on the return spring 201i. When the card block 201e moves to separate from the inclined groove, the rebound force of the return spring 201i can drive the card block 201e to return to its original position. In this way, the reciprocating card block 201e will not drive the rotating rod 201c to rotate when it reverses. When the plug 102 and the socket 101 are completely separated, the protective door 201a can return to its original position to protect the socket 101 again.

[0041] The connecting component 300 is arranged on the rack 201h, and includes a connecting member 301, which includes a movable plate 301a, an extrusion rod 301b, a card frame 301c, a spiral rod 301d, a slope block 301e, an extrusion strip 301f, a limit plate 301h and a lock plate 301i. The movable plate 301a is fixed to one side of the rack 201h, the extrusion rod 301b is located on one side of the movable plate 301a, the card frame 301c is located on one side of the protective door 201a, the spiral rod 301d is inserted into one side of the card frame 301c, the spiral rod 301d and the card frame 301c are movably connected, the slope block 301e is fixed to one side of the card frame 301c, the extrusion strip 301f is arranged on one side of the slope block 301e, the limit plate 301h is arranged above the protective door 201a, and the lock plate 301i is located on one side of the limit plate 301h.

[0042] When the plug 102 and the socket 101 are connected, the plug 102 drives the squeezing rod 301b to squeeze the movable plate 301a, so that the movable plate 301a can move. The movement of the movable plate 301a can drive the rack 201h to move, so that the protective door 201a can be opened.

[0043] There are two spiral rods 301d, and both spiral rods 301d are provided with thread grooves, and the thread grooves on the two spiral rods 301d are set in opposite directions. A card block is provided in the card frame 301c, which slides in the thread groove. The extrusion bar 301f is fixed to one side of the slide bar 302g. When the protective door 201a is opened, the extrusion bar 301f will be driven to move. When the extrusion bar 301f moves, it can squeeze the inclined surface block 301e to make it move. When the inclined surface block 301e moves, it can drive the card frame 301c to move. The movement of the card frame 301c can drive the spiral rod 301d to rotate. Through the movement of the spiral rod 301d The rotation can drive the other screw rod 301d to rotate, and when the other screw rod 301d rotates, it can drive the other clamping frame 301c to move. At this time, the two clamping frames 301c can move toward each other at the same time, and then the plug 102 can be clamped and fixed. After the plug 102 and the socket 101 are connected to open the protective door 201a, the protective door 201a will drive the limiting plate 301h to rise, and then the locking plate 301i is flipped over to make the locking plate 301i engage with the limiting plate 301h, so that the plug 102 can be limited to prevent the plug 102 from falling off the socket 101.

There are two first support rods 202b, which are both fixed on the inner wall of the socket 101. There are two first springs 202c, which are both fixed on the inner wall of the socket 101. When the protective door 201a is opened, the slider 202a will be driven to move. At this time, the slider 202a can be supported by the setting of the first support rod 202b to prevent the slider 202a from deviating. When the slider 202a moves, a squeezing force can be applied to the first spring 202c. When the plug 102 and the socket 101 are separated, the rebound force of the first spring 202c can drive the protective door 201a to return to its original position, thereby allowing the protective door 201a to return to its original position.

The top plate 302j moves to squeeze the slide bar 302g, which can drive the limit plate 301h to move and make it rise. Then, the lock plate 301i is moved to engage with the limit plate 301h, so that the socket 101 and the plug 102 can be limited. The stop shell 302k is used to protect the top plate 302j.

[0058] Specifically, the connecting assembly 300 also includes a toggle member 303, which is arranged on the locking plate 301i, a toggle rod 303a is fixed to one side of the locking plate 301i, a support plate 303b is arranged at one end of the toggle rod 303a, the toggle rod 303a and the support plate 303b are hinged, a second torsion spring 303c is fixed to one side of the toggle rod 303a, the second torsion spring 303c is fixed to one side of the support plate 303b, and the extrusion rod 301b is fixed to one side of the support plate 303b.

[0059] When the lock plate 301i needs to be engaged with the limit plate 301h, the lock plate 301i is toggled, and the lock plate 301i drives the lever 303a to move. The movement of the lever 303a can apply a twisting force to the second torsion spring 303c. The limit plate 301h is provided with a limit groove corresponding to the lock plate 301i. By engaging the lock plate 301i with the limit plate 301h, the socket 101 and the plug 102 can be limited. When the lock plate 301i needs to be separated from the limit plate 301h, the lock plate 301i is pushed forcefully. The limit groove is set as an inclined surface. The lock plate 301i can be separated from the limit plate 301h by pushing forcefully. Then, the rotation force of the second torsion spring 303c can drive the lock plate 301i to return to its original position. The support plate 303b is fixed to the top of the plug 102. The setting of the support plate 303b can support the lever 303a.

[0060] Specifically, it also includes a main body component 100, which is arranged on the protective door 201a, including a socket 101 and a plug 102, the socket 101 is sleeved on the outside of the protective door 201a, the socket 101 and the protective door 201a are movably connected, and the plug 102 is fixed to the bottom of the support plate 303b.

[0061] The socket 101 is fixed to an interface on the battery pack 103, which is used to receive the plug 102 for insertion, thereby establishing an electrical connection so that electrical energy and signals can be transmitted outward through the interface. The plug 102 is a pluggable component with an adapter pin structure. By inserting it into the socket 101, the power transmission and signal transmission channels are opened to ensure the coordinated work of various electrical components and the normal operation of the electrical system.

[0062] Specifically, a battery pack 103 is sleeved on the outer side of the socket 101 .

[0063] The battery pack 103 is an electric energy storage device of the electric vehicle, integrating a plurality of battery cells to provide the electric energy required for driving the vehicle and operating various electric components, and can cooperate with the battery management system to feedback battery status information.

[0064] During use, first, when the socket 101 is not in use, the protective door 201 a is in a closed state, which protects the socket 101 and prevents dust and debris from entering the socket 101 .

[0065] When the plug 102 needs to be connected to the socket 101, the plug 102 is moved close to one side of the socket 101, and the plug 102 will first squeeze the rack 201h to make it move. The movement of the rack 201h drives the gear 201g meshing with it to rotate. The rotation of the gear 201g drives the rotating disk 201f to rotate. The rotation of the rotating disk 201f drives the block 201e to move. The block 201e squeezes the inclined groove provided in the rotating shell 201d, so that the rotating shell 201d rotates. The rotation of the rotating shell 201d drives the rotating rod 201c to rotate. The rotation of the rotating rod 201c drives the pulling frame 201b hinged thereto to move. The movement of the pulling frame 201b drives the protective door 201a to open.

[0066] At the same time, the plug 102 will also drive the extrusion rod 301b to squeeze the movable plate 301a, so that the movable plate 301a moves, and the movement of the movable plate 301a drives the rack 201h to move further, so as to ensure that the protective door 201a is opened smoothly. When the protective door 201a is opened, it will drive the extrusion bar 301f to move, and the extrusion bar 301f moves to squeeze the inclined surface block 301e to make it move, and the inclined surface block 301e moves to drive the clamping frame 301c to move, and the clamping frame 301c moves to drive the spiral rod 301d to rotate. Since the thread grooves on the two spiral rods 301d are arranged in opposite directions, the rotation of one spiral rod 301d will drive the rotation of the other spiral rod 301d, thereby causing the two clamping frames 301c to move toward each other at the same time, clamping and fixing the plug 102.

[0067] Moreover, when the protective door 201a is opened, the limiting plate 301h will be driven to rise. By moving the locking plate 301i, the locking plate 301i will be engaged with the corresponding limiting groove on the limiting plate 301h, thereby limiting the plug 102 and preventing the plug 102 from falling off the socket 101.

[0068] In this process, when the protective door 201a is opened, the slider 202a is driven to move, and the slider 202a moves under the support of the first support rod 202b, and applies a squeezing force to the first spring 202c; when the rotating rod 201c rotates, the rotating column 202f is driven to rotate, and the rotating column 202f rotates to drive the reset disk 202h to rotate, and a twisting force is applied to the first torsion spring 202i. At the same time, the rotating column 202f rotates to drive the guide rod 202j to slide in the positioning frame 202k, and plays a supporting role on the rotating rod 201c. When the card frame 301c moves, it drives the moving block 302c to slide in the sliding frame 302d, and the sliding frame 302d supports the moving block 302c and the card frame 301c; the limit plate 301h moves and drives the pulley 302f to slide in the corresponding sliding groove in the socket 101, playing a supporting role, and at the same time drives the sliding rod 302g to move, and the sliding rod 302g slides on the fixed bar 302h, and the fixed bar 302h supports the sliding rod 302g. The movement of the sliding rod 302g applies a squeezing force to the third spring 302i.

[0069] When the plug 102 is to be separated from the socket 101 , the locking plate 301 i is first pushed with force, and the locking plate 301 i is separated from the limiting plate 301 h by utilizing the inclined surface structure of the limiting groove. Next, the clamping of the plug 102 is released. As the plug 102 is separated from the socket 101, the rack 201h is no longer squeezed. The rack 201h returns to its original position under the action of the relevant elastic elements. The rotating disk 201f drives the block 201e to reverse. The inclined groove on the rotating shell 201d squeezes the block 201e, so that the block 201e moves into the rotating disk 201f. The movement of the block 201e applies a squeezing force to the return spring 201i. When the block 201e moves to separate from the inclined groove, the return spring 201i rebounds and drives the block 201e to return to its original position. Since the reversal of the block 201e will not drive the rotating rod 201c to rotate, the protective door 201a returns to its original position under the action of the rebound force of the first spring 202c, and the socket 101 is protected again. The relevant components also return to their initial state under the action of the corresponding elastic elements such as springs and torsion springs for next use.

[0070] In addition, the socket 101 is fixed to the interface on the battery pack 103. The battery pack 103 serves as an energy storage device for the electric vehicle, providing the vehicle with the power required for driving and operating various electrical components. After the plug 102 is inserted into the socket 101, the power transmission and signal transmission channels are opened to ensure the coordinated work of various electrical components and the normal operation of the electrical system.
