Description

New-energy automobile hood auxiliary lock

Technical field

The present invention relates to field of automobile, it is especially a kind of for new-energy automobile charging when support hood it is auxiliary Help lock.

Background technique

The charge port whole that uses when the fast of new-energy automobile, charging battery at present or in which there is one to be arranged in new energy vapour In the cabin of vehicle, due to charging gun using when can occupy certain space in cabin, need during the charging process keep hood beat Open state faces the stolen risk of important spare part in cabin (such as battery).On the other hand, due to needing to keep in charging process Hood opening state, and hood is in the open state, with the parts spacing such as fender, preceding grid, headlight, cabin sealing strip It is larger, sealing function is lost, hood is unable to satisfy the waterproof requirement of part in cabin.In conclusion be badly in need of one kind is provided can It is smaller to guarantee that hood opens gap in charging, charging gun can be allowed to protrude into cabin and locking hood, it is thief-proof to meet cabin The part of waterproof.

Summary of the invention

Technical problem to be solved by the invention is to provide a kind of new-energy automobile hood auxiliary to latch, it can solve The problem of hood opening easily causes components stolen and is unable to satisfy the waterproof requirement of part in cabin when charging.

To solve the above-mentioned problems, the technical scheme is that this new-energy automobile hood auxiliary lock includes end Head bending, middle part offer the mainboard of pivoted arm card slot, and the head welding of the mainboard and locking bar, the bar tail of the locking bar is " U " The lock of font, the middle part of the locking bar and bracket one weld, and are equipped with sleeve on the bracket one, are set in the sleeve Lock core；The lock core side be equipped with insertion key keyhole, the other side be connected with head be eave tile pivoted arm, the pivoted arm with The lock core rotates and rotates to form unlocking or shut.

In above-mentioned technical proposal, more specifically scheme is: being provided with bushing between the sleeve and the lock core；It is described Retaining ring and liner are provided between pivoted arm and the side of the lock core；It is welded with bracket two on the pivoted arm, the bracket two is 4 The retaining ring and liner are blocked on a direction to be prevented with realizing artificially by breaking sled retaining ring, illegal to open hood auxiliary lock.

Further, the key for opening the lock core is identical as the key that vehicle door lock, ignition lock use, i.e., the described lock Same key can be used in core and vehicle door lock, ignition lock, and vehicle is without being equipped with additional key.

Due to the adoption of the above technical scheme, the invention has the following beneficial effects:

1, the present invention relies on the original hood lock catch of cabin and hood lock, can keep locking in hood opening state, avoid machine The stolen risk of important spare part (such as battery) in cabin；

2, it can guarantee that hood has certain waterproof protective ability in hood opening state using the present invention；

3, same key can be used in lock core of the invention and vehicle door lock, ignition lock, therefore vehicle is not necessarily to be hood auxiliary lock Snap fit is for additional key.

Specific embodiment

Present invention will be further explained below with reference to the attached drawings and examples:

The new-energy automobile hood of Fig. 1 and Fig. 2 assists lock, including mainboard 1, and 1 end of mainboard is bent to form bending part, when use For clasping hood lock catch 13, the pivoted arm card slot for positioning arm, the head weldering of mainboard 1 and locking bar 2 are offered in the middle part of mainboard 1 It connects, the bar tail of locking bar 2 is the lock of "U" shaped, and the lock of "U" shaped is together with 14 padlock of hood lock when use；Locking bar 2 Length can choose different numerical value according to the difference of a variety of models, in the case where basic structure is constant, adapt to various outer The vehicle of sight；The middle part of locking bar 2 and bracket 1 weld, and are equipped with sleeve 5 on bracket 1, lock core 8 is set in sleeve 5；Lock 8 side of core is equipped with the keyhole of insertion key 10, and the other side is connected with the pivoted arm 9 that head is eave tile, and pivoted arm 9 is rotated with lock core 8 And rotate to form unlocking or shut, as shown in Figure 3 and Figure 4.Bushing 6 is provided between sleeve 5 and lock core 8；Pivoted arm 9 and lock Be provided between the side of core 8 retaining ring 11 and liner 7, install lock core 8, pivoted arm 9 arrive sleeve 5 when, using bushing 6, liner 7 every From movement parts, to reduce noise and operating force when operation；Bracket 24 is welded on pivoted arm 9, bracket 24 provides 4 directions Occlusion effect is prevented artificially with realizing by breaking sled retaining ring 11, the illegal function of opening hood auxiliary lock.

The key 10 of opening lock master 8 can be identical as the key that vehicle door lock, ignition lock use, i.e., lock core and vehicle door lock, Ignition lock uses same key, therefore vehicle is not necessarily to increase and being equipped with additional key to the present invention.

Use method of the invention:

Step 1: first the hood of automobile 12 being opened, lifts and supported using bonnet stay, places this invention into the hood of hood Between lock 13 and hood lock 14, as shown in Figure 5；

Step 2: as shown in figure 3, lock core 8 can be operated with key 10, rotate clockwise pivoted arm 9, hood auxiliary lock buckle in Open state；

Step 3: as shown in figure 4, the bending part of mainboard 1 is inserted into hood lock catch 13, and operating lock core 8, revolve pivoted arm 9 counterclockwise Turn, so that the eave tile of pivoted arm 9 is screwed in the pivoted arm card slot of mainboard 1 and is in close state, the present invention is linked together with hood 12 at this time；

Step 4: removing the bonnet stay of hood 12, put down hood, until the "U" shaped lock of locking bar 2 is pressed into hood lock 14 Full lock position；

Step 5: after locking bar 2 and the complete locking of hood lock 14, hood, which is in, at this time is opened but the state of locking, before hood and automobile The space of grid is larger, allows to carry out charging operation using charging gun 15, as shown in Figure 6；

Step 6: after charging operation, removing step of the invention and finish i.e. by installation method sequence inverse operation to removing It can.
