[0042] Reference Figure 1-9 The present application provides a two-stage locking sliding cover structure automobile remote control key, comprising a rear cover 1 and a lower inner cover 2, between which is arranged,
[0043] A primary locking structure, the primary locking structure comprising a plurality of locking grooves 200 provided with first blocks 201 on the rear cover 1 and a plurality of first locking bosses 100 provided on the lower inner cover 2;
[0044] A secondary locking structure, the secondary locking structure comprising a plurality of second locking bosses 300 disposed on the rear cover 1 and a plurality of locking rods 400 provided with second stoppers 401 disposed on the lower inner cover 2; and
[0045] A hook structure, the hook structure comprising a plurality of hooks 500 disposed on the rear cover 1 and a plurality of hooks 500 disposed on the lower inner cover 2;
[0046] The primary locking structure, the secondary locking structure and the hook structure are configured such that when the rear cover 1 is pushed in the first direction, the locking groove 200 can move with the rear cover 1 and enable the first locking boss 100 to pass over the first stopper 201 and slide into the locking groove 200, and at the same time, the second locking boss 300 can move with the rear cover 1 and pass over the second stopper 401 and slide into the locking rod 400 and keep a certain distance from the stopper, and at the same time, the hook 500 on the rear cover 1 can slide into the hook 500 on the lower inner cover 2;
[0047] When the back cover 1 is pushed in a second direction opposite to the first direction, the locking groove 200 can move with the back cover 1 and can enable the first locking boss 100 to pass over the first stop block 201 and slide out of the locking groove 200. At the same time, the second locking boss 300 can move toward the second stop block 401, and the hook 500 slides relative to the hook 500 but does not separate. When the back cover 1 is further pushed in the second direction, the second locking boss 300 can pass over the second stop block 401 and slide out of the locking rod 400. At the same time, the hook 500 on the back cover 1 can slide out of the hook 500 on the lower inner cover 2.
[0048] Specifically, when the rear cover 1 and the lower inner cover 2 are pushed in the first direction for relative movement, the rear cover 1 and the lower inner cover 2 can be locked together, and when the rear cover 1 and the lower inner cover 2 are pushed in the second direction for relative movement, the rear cover 1 and the lower cover can be unlocked and separated, wherein, when the rear cover 1 moves in the second direction, the secondary locking structure can ensure that when the rear cover 1 is loosened, the secondary locking structure can cooperate with the hook structure to prevent the rear cover 1 from being separated from the lower inner cover 2, thereby ensuring that the rear cover 1 is not loosened due to vibration of the car key in a pocket or bag.
[0049] Reference Figure 5 It can be understood that when the second locking boss 300 slides into the locking rod 400, the first locking boss 100 also slides into the locking groove 200. At this time, the rear cover 1 and the lower inner cover 2 are in a locked state. At this time, the distance between the second locking boss 300 and the block is D, D = 1~3mm.
[0050] Specifically, a spacing is reserved between the second locking boss 300 and the second stop block 401 for buffering, which can effectively prevent the secondary locking structure from being easily pushed out and unlocked after the primary locking structure is unlocked, thereby preventing the rear cover 1 from being separated from the lower inner cover 2 due to the unlocking of the primary locking structure when subjected to slight external force or vibration; when the user wants to open the rear cover 1, this spacing can be used to assist, making it easier to push out the rear cover 1.
[0051] Reference Figure 5 It can be understood that the overlap amount between the first locking boss 100 and the locking groove 200 is A, A=0.3-0.5 mm;
[0052] The overlap amount between the second locking boss 300 and the locking rod 400 is B, where B=0.4-0.6 mm.
[0053] Specifically, a certain overlap is maintained between the two-stage locking structures to prevent the two-stage locking structures from being easily unlocked.
[0054] Reference Figure 5-9 It can be understood that the cross section of the first locking boss 100 can be a triangular structure, the cross section of the second locking boss 300 can be a triangular structure, the cross section of the first stopper 201 can be a triangular structure, and the cross section of the second stopper 401 can be a triangular structure.
[0055] Specifically, the cross-sections of the locking boss and the stopper are configured as triangular structures, so that they can have a certain height and width, and can have a push-in side inclined surface and a push-out side inclined surface.
[0056] Combined with reference Figure 6 and 7 It can be understood that the height of the first locking boss 100 is a 1 , a 1 =0.4~0.7mm, width is b 1 , b 1 =1~2mm, the angle of the push-in side slope is α 1 , α 1 =40~60°, the angle of the push-out side slope is β 1 , β 1 =50~70°; the height of the first stopper 201 is a 3 , a 3 =0.4~0.7mm, width is b 3 , b 3 =1~2mm, the angle of the push-in side slope is α 3 , α 3 =40~60°, the angle of the push-out side slope is β 3 , β 3 =50~70°.
[0057] Specifically, the height and width of the first locking boss 100 and the first stop block 201 can be consistent, so as to ensure a suitable overlap and easy adjustment; the pushing surface angles of the first locking boss 100 and the first stop block 201 can be consistent, and such a design can ensure that the back cover 1 is evenly stressed and has moderate force when pushed in; the pushing surface angles of the first locking boss 100 and the first stop block 201 can be consistent and greater than the pushing surface angle, ensuring that the pushing force is greater than the pushing force, and ensuring that the locking structure will not be easily unlocked.
[0058] Reference Figure 8 and 9 It can be understood that the height of the second locking boss 300 is a 2 , a 2 =1.3~2mm, width is b 2 , b 2 =1.5~2.5mm, the angle of the push-in side slope is α 2 , α 2 =20~40°, the angle of the push-out side slope is β 2 , β 2 =50~80°; the height of the second stopper 401 is a 4 , a 4 =0.6~1.5mm, width is b 4 , b 4 =1.5~2.5mm, the angle of the push-in side slope is α 4 , α 4 =20~40°, the angle of the push-out side slope is β4 , β 4 =70~90°.
[0059] Specifically, the height and width of the second locking boss 300 and the second stop block 401 can be consistent, so as to ensure a suitable overlap and easy adjustment; the pushing surface angles of the second locking boss 300 and the second stop block 401 can be consistent, and such a design can ensure that the force is uniform and the force is moderate when the back cover 1 is pushed in; the pushing surface angles of the second locking boss 300 and the second stop block 401 can be consistent and greater than the pushing surface angle, ensuring that the pushing force is greater than the pushing force, and ensuring that the locking structure will not be easily unlocked.
[0060] Reference Figure 5 and 9 It can be understood that the length of the locking rod 400 is 6 to 8 mm.
[0061] Specifically, the second stopper 401 is installed on the lower inner cover 2 via a cantilever, and the second stopper 401 and the cantilever together constitute the locking rod 400 , and the locking rod 400 is an L-shaped structure as a whole.
[0062] Reference Figure 5 and 8 It can be understood that the overlap between the hooks 500 and 500 is C, where C = 2.5 to 5 mm.
[0063] Specifically, the rear cover 1 and the lower inner cover 2 are respectively provided with a plurality of hooks 500, wherein the hooks 500 on the rear cover 1 can be slidably inserted into the corresponding hooks 500 on the lower inner cover 2. When the rear cover 1 and the lower inner cover 2 are locked, the overlap of the hook structure needs to be greater than the distance between the second locking boss 300 and the second stopper 401, so that when the primary locking structure is unlocked, the rear cover 1 is still locked on the lower inner cover 2, will not fall off easily, and can be easily found and restored in time.
