Remote Control

Abstract

This invention provides a remote control, including a housing, a middle housing, a locking component, a battery compartment, and an elastic component. The locking component has a locking portion. The latch includes a first guide portion and a second guide portion connected to the rear side of the first guide portion. Both the first and second guide portions are inclined towards the rear end of the battery compartment. A groove recessed towards the rear end of the battery compartment is formed at the connection between the first and second guide portions. When the battery compartment moves forward, the first guide portion contacts and drives the locking portion to engage with the groove, or the second guide portion contacts and drives the locking portion to disengage from the groove. This allows the battery compartment to engage or disengage from the housing without the need for a switch button and a through hole, and avoids the generation of gaps between the switch button and the through hole, further improving the integrity of the remote control's appearance and preventing friction between the switch button and the housing.

[0078] A slot 625 is formed at the connection between the second guide portion 622 and the first guide portion 621. Specifically, the front end of the second front guide surface 6221 is transitionally connected with the front end of the first rear guide surface 6212 to form the slot 625, which is concave toward the rear end of the battery compartment 6. Optionally, the slot 625 is arc-shaped.

[0079] The card slot 625 can be connected with the card portion 52 to achieve the battery compartment 6 being accommodated in the housing 1 .

[0080] The transition portion 623 is located on one side of the central axis of the engaging member 5 . The transition portion 623 has a second transition surface 6231 parallel to the central axis of the engaging member 5 . The rear end of the second transition surface 6231 is connected to the front end of the second rear guide surface 6222 .

[0081] The blocking portion 624 is located in front of the first guide portion 621, connecting the transition portion 623 and the first guide portion 621. The blocking portion 624 and the first guide portion 621 are arranged on both sides of the central axis of the engaging member 5. The blocking portion 624 has a blocking surface 6241, a third guide surface 6242 and a first transition surface 6243.

[0082] The third guide surface 6242 is inclined relative to the rear end surface of the battery compartment 6 , and is in the same plane as and connected to the first front guide surface 6211 . Specifically, the third guide surface 6242 connects the front end of the first front guide surface 6211 and the front end of the blocking surface 6241 .

[0083] The connection between the third guide surface 6242 and the blocking surface 6241 is located on one side of the central axis surface of the engaging member 5 .

[0084] The third guide surface 6242 and the blocking surface 6241 are connected in a smooth transition, thereby improving the smoothness of the movement of the engaging portion 52 from the blocking surface 6241 to the third guide surface 6242 .

[0085] The blocking surface 6241 is inclined relative to the rear end surface of the battery compartment 6, connects the front end of the second transition surface 6231 and the front end of the third guide surface 6242, and protrudes toward the side of the third guide surface 6242 facing away from the central axis surface of the engaging member 5, and is connected to the second rear guide surface 6222 via the second transition surface 6231, wherein the swing angle of the engaging portion 52 at the blocking surface 6241 is greater than the swing angle of the engaging portion 52 at the second transition surface 6231.

[0086] Optionally, the blocking surface 6241 is smoothly connected to the second transition surface 6231 , thereby improving the smoothness of the movement of the engaging portion 52 from the second transition surface 6231 to the blocking surface 6241 .

[0087] The first transition surface 6243 connects the blocking surface 6241 and the third guide surface 6242 and is located between the blocking surface 6241 and the third guide surface 6242, wherein the first transition surface 6243, the central axis surface of the engaging member 5 and the second transition surface 6231 are parallel to each other.

[0088] Optionally, the first transition surface 6243 is smoothly transitionally connected to the blocking surface 6241 and the third guide surface 6242 , respectively, so as to improve the smoothness of the movement of the engaging portion 52 from the blocking surface 6241 to the third guide surface 6242 .

[0089] In addition, there are two clips 62 corresponding to the two engaging parts 52. The two clips 62 are respectively installed on the front and back sides of the battery compartment 6, and are 180 degrees rotationally symmetrical, so that the two clips 62 contact and drive the two engaging parts 52 to move in the opposite direction. When the two engaging parts 52 move in the opposite direction, they are respectively subjected to two reverse forces and achieve elastic retraction under the action of the two reverse forces.

[0090] When the engaging portion 52 contacts the slot 625 along the first guide portion 621, the two engaging portions 52 elastically retract into the corresponding slot 625 under the action of two opposite forces, so that the two engaging portions 52 automatically engage with the corresponding slot 625. In addition, the two engaging portions 52 respectively squeeze the inner wall of the corresponding slot 625 under the elastic force of the elastic member 7.

[0091] When the engaging portion 52 is separated from the buckle 62 along the blocking portion 624 , the two engaging portions 52 elastically retract and return to their original positions under the action of two opposing forces.

[0092] A fixing seat 63 is protruded from the battery compartment 6, and the fixing seat 63 is optionally in the same direction as the buckle 62. The remote controller 100 further includes a wear-resistant block 8, which is mounted on the fixing seat 63 and extends beyond the fixing seat 63 in the thickness direction to abut against the inner wall of the housing 1. The friction between the wear-resistant block 8 and the inner wall of the housing 1 increases the sliding resistance of the battery compartment 6, thereby preventing the battery compartment 6 from sliding out of the housing 1 due to excessive sliding force.

[0093] The elastic member 7 extends into the receiving cavity 11. One end of the elastic member 7 is buckled with the rear end of the circuit board 3 and is installed on the middle shell 4 through the circuit board 3. The other end of the elastic member 7 elastically abuts against the battery compartment 6 and applies a backward elastic force to the front end of the battery compartment 6.

[0094] Slot 625 Slot 625 Specifically, the elastic member 7 is a spring and is in a compressed state when it abuts against the front end of the battery compartment 6 .

[0095] Optionally, there are multiple elastic members 7 , and the multiple elastic members 7 are arranged on both sides of the engaging member 5 to improve the stability of the battery compartment 6 .

[0096] Furthermore, the elastic member 7 is made of conductive material, which can be copper. One end of the elastic member 7 is buckled on the rear end of the circuit board 3 , and the other end is abutted on the battery compartment 6 , so that the circuit board 3 is electrically connected to the battery compartment 6 through the elastic member 7 .

[0097] The operation flow of the remote controller 100 according to the embodiment of the present invention is as follows:

[0098] When the battery compartment 6 needs to be inserted into the receiving cavity 11 of the casing 1, the battery compartment 6 is inserted into the opening 12 and received in the receiving cavity 11 through the opening 12, wherein the rear end of the battery compartment 6 moves forward under the action of the thrust, and the first guide portion 621 of the buckle 62 first contacts the engaging portion 52, and drives the engaging portion 52 to move to the engaging groove 625 along the first front guide surface 6211 and the first rear guide surface 6212 in sequence, wherein the two engaging portions 52 of the engaging member 5 converge at the engaging groove 625 under the action of their own rebound force, and the elastic member 7 applies a backward elastic force to the front end of the battery compartment 6, so that the engaging portion 52 is buckled in the engaging groove 625 under the elastic force of the elastic member 7, thereby realizing that the battery compartment 6 is received in the receiving cavity 11.

[0099] The engaging portion 52 is buckled in the slot 625 under the elastic force of the elastic member 7, and the engaging portion 52 is subjected to two opposite forces at the slot 625, thereby improving the engagement strength between the engaging member 5 and the buckle 62. The elastic force of the elastic member 7 improves the buckling stability with the slot 625.

[0100] When the battery compartment 6 needs to be separated from the accommodating cavity 11 of the casing 1, the rear end of the battery compartment 6 is pushed again and moves forward again under the action of the thrust. The second guide portion 622 of the buckle 62 contacts the locking portion 52 and drives the locking portion 52 to separate from the locking slot 625 along the second front guide surface 6221 and the second rear guide surface 6222 in sequence. The elastic member 7 applies a backward elastic force to the front end of the battery compartment 6, so that the locking portion 52 separates from the outside of the locking slot 625 under the elastic force of the elastic member 7 and slides along the second transition surface 6231.

[0101] When the blocking portion 624 of the buckle 62 contacts the locking portion 52, the front end portion of the battery compartment 6 is still accommodated in the accommodating cavity 11, and the blocking portion 624 limits the locking portion 52 from detaching outward, and the locking portion 52 is subjected to resistance at the rear end of the blocking surface 6241. The resistance prevents the battery compartment 6 from directly detaching from the accommodating cavity 11, and avoids the battery compartment 6 from flying out of the casing 1, so that the battery compartment 6 can only be completely detached from the accommodating cavity 11 under the action of a pulling force, wherein the battery compartment 6 moves along the blocking surface 6241 and the first transition surface 6243 in sequence, and the third guide surface 6242 facilitates contact with the buckle 62 again.

[0102] When the engaging portions 52 are separated from the first transition surface 6243 , the two engaging portions 52 are reset under the action of their own resilience. At this time, the axes of the two engaging portions 52 and the axis of the mounting portion 51 are in the same plane.

[0103] It can be seen from the above technical solutions that the embodiments of the present invention have at least the following advantages and positive effects:

[0104] In the remote control 100 of the embodiment of the present invention, a locking portion 52 is provided on the locking member 5, and the buckle 62 includes a first guide portion 621 and a second guide portion 622 connected to the rear side of the first guide portion 621. The first guide portion 621 and the second guide portion 622 are both inclined toward the rear end of the battery compartment 6, and a slot 625 recessed toward the rear end of the battery compartment 6 is formed at the connection between the first guide portion 621 and the second guide portion 622. When the battery compartment 6 moves forward, the first guide portion 621 contacts and drives the locking portion 52 to engage the slot 625, or the second guide portion 622 contacts and drives the locking portion 52 to disengage from the slot 625, so that the battery compartment 6 can be engaged with or disengaged from the casing 1 without the need for a switch button and a through hole, and the generation of a gap between the switch button and the through hole is avoided, thereby further improving the integrity of the appearance of the remote control 100 and avoiding friction between the switch button and the casing 1. In addition, the elastic member 7 can provide a backward elastic force to the battery compartment 6 , so that the engaging portion 52 is subjected to two opposite forces at the engaging slot 625 , thereby improving the engaging strength between the engaging member 5 and the buckle 62 .

[0105] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
