Description

Technical Field

[0001] The present invention relates to the technical field of wire harness connectors, and particularly to a wire harness connector for electric vehicles. Background Art

[0002] The wire harness connector for electric vehicles is a crucial component in the electrical system of electric vehicles. It mainly consists of a plug, a socket, and a protective housing, and is connected through plugging and unplugging operations. Its function is to connect numerous electrical components such as batteries with wire harnesses to form an electrical circuit, which can not only transmit electric energy stably and efficiently to ensure the normal operation of each electrical device, but also connect the plug to the socket, which has an important role. Such a connection method can build a bridge between the battery and other electrical components of the vehicle, enabling electric energy to be stably transmitted from the battery and providing power support for motors, on-board chargers, various sensors, and other electrical devices. At the same time, it can also accurately transmit battery-related monitoring signals, control signals, etc. through this connection channel to the corresponding control unit, thereby ensuring the normal operation of the entire electrical system of the electric vehicle and the coordinated operation of each component, and realizing various functions such as driving the vehicle, charging, and real-time status monitoring. Since the socket has no protection, during the daily use, maintenance, and repair of the vehicle, it is easily accidentally collided and scratched by tools, spare parts, etc., which may cause the socket housing to crack, the pins to bend or break, etc. Moreover, different sockets have strictly corresponding plugs. During the actual operation process, due to the large number of sockets inside electric vehicles and the possible similarity in appearance, size, etc. among the sockets, the situation of plugging in the wrong plug often occurs, which will cause the vehicle's control system to make wrong judgments and regulations based on wrong signals, affecting the normal implementation of functions such as battery thermal management and vehicle driving state adjustment, and resulting in potential safety hazards such as overheating of the battery due to improper temperature control. Summary of the Invention

DETAILED DESCRIPTION

[0037] 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.

[0038] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0039] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive with other embodiments.

[0040] Embodiment 1

[0041] Referring to Figures 2 to 17 , this is the first embodiment of the present invention. This embodiment provides an electric vehicle wiring harness connector. The electric vehicle wiring harness connector includes a protection component 200, a connection component 300, and a main body component 100. The cooperation of the three can prevent the socket from being damaged during daily use and maintenance, and it can be automatically opened without manual operation. It only opens when the matching plug is inserted, which can prevent misinsertion, improve the accuracy and standardization of operation, and reduce the risk of equipment damage caused by misinsertion.

[0042] The protection component 200 includes a protection member 201. The protection member 201 includes a protection door 201a, a pulling frame 201b, a rotating rod 201c, a rotating shell 201d, a clamping 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. The rotating shell 201d is fixed to one side of the rotating rod 201c. The clamping block 201e is located inside the rotating shell 201d. The rotating disk 201f is sleeved outside the clamping block 201e. The rotating disk 201f and the clamping block 201e are hinged. The gear 201g is fixed to one side of the rotating disk 201f. The rack 201h is arranged 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 clamping block 201e, and the other end is fixed to the inner wall of the rotating disk 201f.

[0043] When the socket 101 is not in use, the socket 101 can be protected by the setting of the protective door 201a to prevent dust and sundries from entering the socket 101. When it is necessary to connect the plug 102 to the socket 101, when the plug 102 is close to one side of the socket 101, the rack 201h will be squeezed and move. The movement of the rack 201h will drive the gear 201g to rotate. At this time, the rotation of the gear 201g will drive the rotating disc 201f to rotate. The rotation of the rotating disc 201f will drive the block 201e to move. There is an inclined groove corresponding to the block 201e in the rotating shell 201d. By squeezing the inclined groove with the block 201e, 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. By the rotation of the rotating rod 201c, the pulling frame 201b can be driven to move. The movement of the pulling frame 201b can drive the protective door 201a to move and open it. Then continue to move the plug 102 to connect it to the socket 101. When the plug 102 is separated from the socket 101 to relieve the extrusion of the rack 201h, at this time the rack 201h will return to its original position. When the rack 201h returns to its original position, the rotating disc 201f will drive the block 201e to reverse. Then, the inclined groove on the rotating shell 201d will squeeze the block 201e, so that the block 201e moves into the rotating disc 201f. When the block 201e moves, it can exert an extrusion force on the return spring 201i. When the block 201e moves away from the inclined groove, the return force of the return spring 201i can drive the block 201e to return to its original position. In this way, the reverse rotation of the block 201e will not drive the rotating rod 201c to rotate. 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.

[0044] The connection component 300 is arranged on the rack 201h and includes a connecting piece 301. The connecting piece 301 includes a movable plate 301a, a pressing rod 301b, a clamping frame 301c, a screw rod 301d, an inclined block 301e, a pressing strip 301f, a limiting plate 301h and a locking plate 301i. The movable plate 301a is fixed on one side of the rack 201h. The pressing rod 301b is located on one side of the movable plate 301a. The clamping frame 301c is located on one side of the protective door 201a. The screw rod 301d is inserted into one side of the clamping frame 301c. The screw rod 301d is movably connected with the clamping frame 301c. The inclined block 301e is fixed to one side of the clamping frame 301c. The pressing strip 301f is arranged on one side of the inclined block 301e. The limiting plate 301h is arranged above the protective door 201a. The locking plate 301i is located on one side of the limiting plate 301h.

[0045] When connecting the plug 102 and the socket 101, the plug 102 drives the extrusion rod 301b to extrude the movable plate 301a, so that the movable plate 301a can be moved. By moving the movable plate 301a, the rack 201h can be driven to move, so that the protective door 201a can be opened.

[0046] There are two screw rods 301d. Thread grooves are provided on both of the two screw rods 301d. The thread grooves on the two screw rods 301d are arranged in opposite directions. A clamping block is arranged in the clamping frame 301c and slides in the thread groove. The extrusion strip 301f is fixed to one side of the sliding rod 302g. When the protective door 201a is opened, it drives the extrusion strip 301f to move. When the extrusion strip 301f moves, it can extrude the inclined plane block 301e to make it move. When the inclined plane block 301e moves, it can drive the clamping frame 301c to move. When the clamping frame 301c moves, it can drive the screw rod 301d to rotate. By rotating the screw rod 301d, the other screw rod 301d can be driven to rotate. 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 towards each other at the same time, and then the plug 102 can be clamped and fixed. After connecting the plug 102 and the socket 101 and opening the protective door 201a, the protective door 201a drives the limiting plate 301h to rise, and then flips the locking plate 301i to make the locking plate 301i engage with the limiting plate 301h, so as to limit the plug 102 and prevent the plug 102 from detaching from the socket 101.

[0047] Embodiment 2

[0048] Refer to Figures 1 to 17 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0049] Specifically, the protection component 200 further includes a support member 202, which is arranged on the protective door 201a. A slider 202a is fixed on one side of the protective door 201a. A first support rod 202b is inserted into the top of the slider 202a. The slider 202a and the first support rod 202b are movably connected. A first spring 202c is fixed on the top of the slider 202a.

[0050] There are two slider 202a, which are respectively fixed on both sides of the protective door 201a. There are two first support rods 202b, both of which are fixed on the inner wall of the socket 101. There are two first springs 202c, both of which are fixed on the inner wall of the socket 101. When the protective door 201a is opened, it will drive the slider 202a to move. At this time, the first support rod 202b can support the slider 202a to prevent the slider 202a from shifting. When the slider 202a moves, it can exert an extrusion force on the first spring 202c. When the plug 102 and the socket 101 are separated, at this time, the force of the first spring 202c rebounding can drive the protective door 201a to return to its original position, so that the protective door 201a can return to its original position.

[0051] Specifically, a positioning plate 202d is sleeved outside the rotating rod 201c. The positioning plate 202d and the rotating rod 201c are rotatably connected through a rotating shaft. A protective cover 202e is sleeved outside the positioning plate 202d. A rotating column 202f is fixed on one side of the rotating rod 201c. A blocking cover 202g is sleeved outside the rotating column 202f. The rotating column 202f and the blocking cover 202g are rotatably connected through a bearing. The blocking cover 202g is fixed on the inner wall of the protective cover 202e.

[0052] The positioning plate 202d is used to support the rotating rod 201c to prevent the rotating rod 201c from shifting. The protective cover 202e is fixed on one side of the socket 101. Through the setting of the protective cover 202e, the positioning plate 202d can be supported to prevent the positioning plate 202d from shifting. When the rotating rod 201c rotates, it can drive the rotating column 202f to rotate. When it is necessary to make the rotating rod 201c rotate back to its original position, the rotation of the rotating column 202f can drive the rotating rod 201c to rotate back to its original position. Through the setting of the blocking cover 202g, the rotating column 202f can be supported to prevent the rotating column 202f from shifting.

[0053] Specifically, a reset disc 202h is sleeved outside the rotating column 202f. A first torsion spring 202i is fixed on one side of the reset disc 202h.

The positioning strip 202l and the rack 201h are movably connected.

[0054] When the rotating column 202f rotates, it can drive the reset disk 202h to rotate. By rotating the reset disk 202h, a torsional force can be applied to the first torsion spring 202i. When the rotating column 202f rotates, it will drive the guide rod 202j to slide within the positioning frame 202k, thereby supporting the rotating rod 201c and preventing the rotating rod 201c from shifting during rotation. Through the return force of the first torsion spring 202i, the rotating column 202f can be driven to rotate back to its original position. When the rack 201h moves, it can move on the positioning strip 202l, thereby supporting the rack 201h and preventing the rack 201h from shifting during movement. A compression spring is fixed on one side of the positioning strip 202l, and the compression spring is fixed to the inner wall of the rack 201h. When the rack 201h is moved, a compressive force can be applied to the compression spring. When the compression on the rack 201h is released, the return force of the compression spring can drive the rack 201h back to its original position for the next use.

A second spring 302b is fixed on one side of the positioning block 302a, and one end of the second spring 302b is fixed to one side of the card frame 301c.

[0056] The positioning block 302a is fixed to one side of the socket 101. By providing the positioning block 302a, the screw rod 301d can be supported to prevent the screw rod 301d from shifting. When the card frame 301c moves, a compressive force can be applied to the second spring 302b. When the second spring 302b rebounds, it can support the card frame 301c when it returns to its original position to prevent the card frame 301c from shifting. A connecting plate is provided at one end of the screw rod 301d, and the connecting plate and the screw rod 301d are rotatably connected by a bearing. The connecting plate is fixed to one side of the socket 101. By providing the connecting plate, the screw rod 301d can be supported.

[0057] Specifically, a moving block 302c is fixed to the bottom of the card frame 301c, and a sliding frame 302d is sleeved outside the moving block 302c. The moving block 302c is slidably connected within the sliding frame 302d.

[0058] When the card frame 301c moves, it can drive the moving block 302c to slide within the sliding frame 302d. The sliding frame 302d is fixed to one side of the socket 101. By providing the sliding frame 302d, the moving block 302c can be supported, and the moving block 302c can support the card frame 301c to prevent the card frame 301c from shifting during movement.

[0062] A slide groove corresponding to the pulley 302f is opened in the socket 101, and the limit plate 301h can drive the pulley 302f to slide in the slide groove when moving, so as to support the limit plate 301h and prevent the limit plate 301h from deflecting, and when the limit plate 301h moves, it will drive the slide bar 302g to move, and the slide bar 302g will slide on the fixed bar 302h, and the fixed bar 302h is fixed to the inner wall of the socket 101. The setting of the fixed bar 302h can support the slide bar 302g to prevent the slide bar 302g from deflecting, and the slide bar 302g can support the third The spring 302i is squeezed, and when the limit plate 301h needs to return to its original position, the rebound force of the third spring 302i can drive the limit plate 301h to return to its original position. When the protective door 201a moves to open and drives the slider 202a to move, the slider 202a will drive the top plate 302j to move. 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.

[0063] 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.

[0064] When it is necessary to engage the locking plate 301i with the limiting plate 301h, the locking plate 301i is toggled. At this time, the locking plate 301i will drive the lever 303a to move. The movement of the lever 303a can apply a torsional force to the second torsion spring 303c. A limiting groove corresponding to the locking plate 301i is provided on the limiting plate 301h. By engaging the locking plate 301i with the limiting plate 301h, the socket 101 and the plug 102 can be limited. When it is necessary to separate the locking plate 301i from the limiting plate 301h, the locking plate 301i is forcefully toggled. The limiting groove is set as an inclined surface, and forcefully toggling can separate the locking plate 301i from the limiting plate 301h. Then, the force of the second torsion spring 303c rotating can drive the locking plate 301i to return to its original position. The support plate 303b is fixed to the top of the plug 102, and the support plate 303b can support the lever 303a.

[0065] Specifically, it further includes a main body assembly 100, which is arranged on the protective door 201a and includes a socket 101 and a plug 102. The socket 101 is sleeved on the outside of the protective door 201a, and the socket 101 is movably connected to the protective door 201a. The plug 102 is fixed to the bottom of the support plate 303b.

[0066] The socket 101 is a connector fixed on the battery pack 103 for receiving the plug 102 to be inserted, thereby establishing an electrical connection so that electrical energy and signal energy can be transmitted outward through this connector. The plug 102 is a pluggable component with an adapted pin structure. By inserting it into the socket 101, the electrical energy transmission and signal transmission channels are opened to ensure the coordinated operation of each electrical component and the normal operation of the electrical system.

[0067] Specifically, a battery pack 103 is sleeved on the outside of the socket 101.

[0068] The battery pack 103 is an electrical energy storage device of an electric vehicle, integrating numerous battery cells, providing electrical energy for the vehicle to drive and for each electrical component to operate, and can cooperate with the battery management system to feedback battery status information.

[0069] During use, first, when the socket 101 is not in use, the protective door 201a is in a closed state, which plays a protective role for the socket 101 to prevent dust, debris, etc. from entering the socket 101.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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 springs, torsion springs and other elastic elements for next use.

[0075] 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.
