Description

Technical Field

[0001] This utility model relates to the field of charging device technology, and more specifically, to an adapter. Background Technology

[0002] With the increasing number of new energy vehicles, the demand for vehicle charging is growing daily, and users' demand for diversified adapters is also increasing. Traditional new energy vehicle adapters require connecting the charging gun first and then the electric vehicle charging dock. However, this cannot meet the needs of some users who require connecting the vehicle charging dock first and then the charging gun. In addition, the traditional method of using electronic locks to lock the charging gun and the car charging dock increases manufacturing costs due to the added electronic lock components, which does not meet the cost reduction requirements of new energy vehicles.

[0003] Therefore, in order to meet customers' diverse needs for adapters and their need to reduce costs, a new adapter solution is urgently needed to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a new technology solution for an adapter to address the user's need to connect the vehicle-side charging dock first, followed by the charging gun, and the problem that only electronic locks can be used for locking, which increases manufacturing costs.

[0005] According to this utility model, an adapter is provided, including an adapter main housing, one end of which is provided with a gun end interface for plugging in a charging gun, and the other end is provided with a vehicle end interface for plugging in a vehicle end charging socket. A linkage double locking mechanism is disposed in the adapter main housing, including a first locking rod, a transmission mechanism, and a second locking rod connected in sequence. The first locking rod has a first locking shaft that locks with the gun end interface, and the second locking rod has a second locking shaft that locks with the vehicle end interface. The second locking shaft drives the transmission mechanism, thereby moving the first locking shaft.

[0006] Optionally, the second locking shaft drives the transmission mechanism to move the first locking shaft linearly from the gun end interface to the vehicle end interface.

[0007] Optionally, the transmission mechanism is a turntable linkage assembly, including a first guide post perpendicularly connected to the first locking shaft, a turntable, and a second guide post perpendicularly connected to the second locking shaft. The turntable is provided with two circumferentially distributed arc-shaped slide rails that are slidably connected to the first guide post and the second guide post, respectively.

[0008] Optionally, a linkage shaft is fixed inside the main housing of the adapter, and the turntable is sleeved on the linkage shaft to achieve bidirectional translation drive.

[0009] Optionally, the transmission mechanism is a gear transmission assembly, including a first rack on the first locking rod, a second rack on the second locking rod, and gears meshing with both.

[0010] Optionally, the first locking rod further includes a first transmission part connected to the first locking shaft and extending axially, and the second locking rod further includes a second transmission part connected to the second locking shaft and extending parallel to its axis. The first rack is disposed on the first transmission part, and the second rack is disposed on the second transmission part, and they are arranged parallel to each other and on both sides of the gear.

[0011] Optionally, a linkage shaft is fixed inside the main housing of the adapter, and the gear shaft is fixed on the linkage shaft.

[0012] Optionally, the linkage double locking mechanism further includes a reset assembly disposed on the second locking rod. The reset assembly includes: a vertical plate perpendicularly connected to the second locking shaft, a core rod extending axially away from the second locking shaft from the vertical plate, and a compression spring sleeved on the core rod. The end of the core rod is slidably inserted into a fixing plate inside the adapter main housing. The second locking rod is driven to reset by the elastic restoring force of the compression spring, and the first locking rod is synchronously linked to restore the locking state.

[0013] Optionally, a first unlocking button is pivotally connected to the outer wall of the gun end interface. One end of the first unlocking button is inserted and locked to the first locking shaft, and the other end has a snap-fit ​​protrusion embedded inside the gun end interface.

[0014] Optionally, the adapter main housing is provided with a second unlock button near the vehicle end interface. The second unlock button has a locking arm, which is engaged with the charging dock through a press-type pivot structure to form a double unlock redundancy.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model provides a linkage-type double-locking rod locking mechanism within the main housing of the adapter, comprising a first locking rod, a transmission mechanism, and a second locking rod connected in sequence. The first locking rod has a first locking shaft that locks with the gun end interface, and the second locking rod has a second locking shaft that locks with the vehicle end interface. When the vehicle end interface of this adapter is plugged into the vehicle end charging socket, the second locking shaft moves linearly under the action of the plugging force, driving the transmission mechanism to move the first locking shaft, thereby unlocking the locking between the first locking shaft and the gun end interface, allowing the charging gun to be plugged in for vehicle charging. Currently, new energy vehicle adapters use a method of connecting the charging gun first and then the electric vehicle charging socket. Based on different user needs, this solution satisfies the charging sequence of connecting the vehicle end charging socket first and then the charging gun, fully ensuring user safety. Furthermore, the mechanical structure of the linkage-type double-locking rod locking mechanism replaces the electronic lock, achieving the effect of reducing manufacturing costs and improving product reliability.

[0017] 2. This utility model also provides a reset component on the second locking rod. After the adapter vehicle-side interface is pulled out from the vehicle-side charging socket, the second locking rod can be driven to reset under the elastic restoring force of the compression spring of the reset component. The movement of the second locking rod is synchronized with the first locking rod to restore the locking state, preventing unintended insertion of the gun-side interface and ensuring electrical safety.

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] According to the adapter provided by this utility model, such as Figures 1-4 As shown, the adapter includes a main housing 10, one end of which has a gun-end interface 30 for plugging in a charging gun, and the other end has a vehicle-end interface 20 for plugging in a vehicle-end charging socket. A linkage-type double locking mechanism is disposed inside the main housing 10, including a first locking rod, a transmission mechanism, and a second locking rod connected in sequence. The first locking rod has a first locking shaft 431 that locks with the gun-end interface 30, and the second locking rod has a second locking shaft 411 that locks with the vehicle-end interface 20. The second locking shaft 411 drives the transmission mechanism, thereby moving the first locking shaft 431.

[0031] With the increasing number of new energy vehicles, the demand for vehicle charging is growing daily, and users' demand for diversified adapters is also increasing. Traditional new energy vehicle adapters require connecting the charging gun first and then the electric vehicle charging dock. However, this cannot meet the needs of some users who require connecting the vehicle charging dock first and then the charging gun. In addition, the traditional method of using electronic locks to lock the charging gun and the car charging dock increases manufacturing costs due to the added electronic lock components, which does not meet the cost reduction requirements of new energy vehicles.

[0032] This utility model incorporates a linkage-type double-locking rod locking mechanism within the adapter's main housing 10. This mechanism includes a first locking rod, a transmission mechanism, and a second locking rod connected sequentially. The first locking rod has a first locking shaft 431 that locks to the gun-end interface 30, and the second locking rod has a second locking shaft 411 that locks to the vehicle-end interface 20. When the vehicle-end interface 20 of this adapter is plugged into the vehicle-end charging socket, the second locking shaft 411 moves linearly under the insertion force, driving the transmission mechanism and causing the first locking shaft 431 to move. This unlocks the locking between the first locking shaft 431 and the gun-end interface 30, allowing the charging gun to be plugged in for vehicle charging. Currently, new energy vehicle adapters typically connect the charging gun first, then the electric vehicle charging socket. Based on different user needs, this solution allows for charging in the order of connecting the vehicle-end charging socket first, followed by the charging gun, ensuring user safety. Furthermore, the linkage-type double-locking rod locking mechanism replaces the electronic lock, reducing manufacturing costs and improving product reliability.

[0033] In some embodiments, such as Figures 1-4 As shown, the second locking shaft 411 drives the transmission mechanism, causing the first locking shaft 431 to move linearly from the gun end interface 30 to the vehicle end interface 20.

[0034] When the vehicle-side interface 20 of this adapter is plugged into the vehicle-side charging socket, the second locking shaft 411 moves linearly towards the first locking shaft 431 under the action of the plugging force, and drives the transmission mechanism to rotate. The rotation of the transmission mechanism causes the first locking shaft 431 to move linearly towards the second locking shaft 411, that is, to retract into the adapter main housing 10 to unlock, so as to unlock the locking of the first locking shaft 431 and the gun-side interface 30, and then the charging gun is plugged in to charge the vehicle, which meets the customer's need to connect the vehicle-side charging socket first and then connect the charging gun for charging.

[0035] In some embodiments, such as Figures 1-2As shown, the transmission mechanism is a turntable linkage assembly 40, which includes a first guide post 432 perpendicularly connected to the first locking shaft 431, a turntable 42, and a second guide post 413 perpendicularly connected to the second locking shaft 411. The turntable 42 is provided with two circumferentially distributed arc-shaped slide rails 421 that are opposite to each other, which are slidably connected to the first guide post 432 and the second guide post 413 respectively.

[0036] When the vehicle-side interface 20 of this adapter is plugged into the vehicle-side charging dock, the second locking shaft 411, under the action of the plugging force, drives the second guide post 413 to slide in its corresponding arc-shaped slide rail 421, and drives the transmission mechanism to rotate. The rotation of the transmission mechanism drives the first guide post 432 to slide in its corresponding arc-shaped slide rail 421, thereby driving the first locking shaft 431 to move linearly in the direction of the second locking shaft 411, that is, to retract and unlock inward into the adapter main housing 10, so as to unlock the locking of the first locking shaft 431 and the gun-side interface 30, and then plug in the charging gun to charge the vehicle, thus meeting the customer's need to connect the vehicle-side charging dock first and then connect the charging gun for charging.

[0037] In some embodiments, such as Figures 1-2 As shown, a linkage shaft 44 is fixed inside the adapter main housing 10, and the turntable 42 is sleeved on the linkage shaft 44 to realize bidirectional translation drive.

[0038] The linkage shaft 44 enables the turntable 42 to rotate and to move the first locking shaft 431 and the second locking shaft 411 on both sides in a bidirectional translation.

[0039] In some embodiments, such as Figures 3-4 As shown, the transmission mechanism is a gear transmission assembly 40, which includes a first rack 434 provided on the first locking rod, a second rack 415 provided on the second locking rod, and a gear 45 meshing with the two.

[0040] When the vehicle-side interface 20 of this adapter is plugged into the vehicle-side charging socket, the second locking shaft 411 is driven by the insertion force to rotate through the first rack 434 to drive the gear 45. The rotation of the gear 45 drives the first locking shaft 431 to move linearly in the direction of the second locking shaft 411 through the second rack 415, that is, to retract and unlock inward into the adapter main housing 10, so as to unlock the locking of the first locking shaft 431 and the gun-side interface 30, and then the charging gun is plugged in to charge the vehicle, which meets the customer's need to connect the vehicle-side charging socket first and then connect the charging gun for charging.

[0041] In some embodiments, such as Figures 3-4As shown, the first locking rod further includes a first transmission part 433 connected to the first locking shaft 431 and extending axially, and the second locking rod further includes a second transmission part 414 connected to the second locking shaft 411 and extending parallel to its axis. The first rack 434 is disposed on the first transmission part 433, and the second rack 415 is disposed on the second transmission part 414, and they are arranged parallel to each other and on both sides of the gear 45.

[0042] In some embodiments, such as Figures 3-4 As shown, a linkage shaft 44 is fixed inside the adapter main housing 10, and the gear 45 is fixed on the linkage shaft 44.

[0043] The linkage shaft 44 provides a rotation center for the gear 45, thereby enabling the linear motion of the first locking shaft 431 and the second locking shaft 411 on both sides through a transmission connection.

[0044] In some embodiments, such as Figures 1-4 As shown, the linkage double locking mechanism further includes a reset assembly disposed on the second locking rod. The reset assembly includes: a vertical plate 412 perpendicularly connected to the second locking shaft 411, a core rod 416 extending axially away from the second locking shaft 411 from the vertical plate 412, and a compression spring 417 sleeved on the core rod 416. The end of the core rod 416 is slidably inserted into a fixing plate 418 inside the adapter main housing 10. The second locking rod is driven to reset by the elastic restoring force of the compression spring 417, and the first locking rod is synchronously linked to restore the locking state.

[0045] After the adapter vehicle-side interface 20 is pulled out from the vehicle-side charging dock, the second locking lever can be driven to reset under the elastic restoring force of the compression spring 417 of the reset component, and the first locking lever is simultaneously linked to restore the locking state, preventing unintended insertion of the gun end and ensuring electrical safety.

[0046] In some embodiments, such as Figure 1 and Figure 3 As shown, a first unlocking button 50 is pivotally connected to the outer wall of the gun end interface 30. One end of the first unlocking button 50 is inserted and locked to the first locking shaft 431, and the other end has a snap-fit ​​protrusion 51 embedded inside the gun end interface 30.

[0047] In the initial state, the second locking shaft 411 is locked to the vehicle-end interface 20. The first unlocking button 50 has a locking hole facing the first locking shaft 431. The free end of the first locking shaft 431 is inserted into the locking hole and locked with the first unlocking button 50. The locking protrusion 51 is embedded inside the gun-end interface 30. The setting of the locking protrusion 51 prevents the charging gun from being inserted until the vehicle-end interface 20 is inserted into the vehicle-end charging socket. Under the action of the insertion force, the second locking shaft 411 moves linearly towards the first locking shaft 431 and drives the transmission mechanism to rotate. The rotation of the transmission mechanism drives the first locking shaft 431 to move linearly towards the second locking shaft 411 to unlock the locking of the first locking shaft 431 and the first unlocking button 50, fully exposing the gun-end interface 30. The charging gun is then inserted to charge the vehicle in the unlocked state.

[0048] In some embodiments, such as Figure 1 and Figure 3 As shown, the adapter main housing 10 is provided with a second unlock button 60 near the vehicle end interface 20. The second unlock button 60 has a locking arm 61, which is engaged with the charging dock through a press-type pivot structure to form a double unlocking redundancy.

[0049] The locking arm 61 of the second unlock button 60 engages with the charging dock. This serves two purposes: first, it strengthens the locking of the second locking shaft 411 with the charging dock, ensuring a secure connection between the adapter and the vehicle charging dock during charging; second, it prevents the adapter from unexpectedly detaching from the vehicle charging dock, thus ensuring electrical safety.

[0050] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
