Detailed Implementation

[0008] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain this utility model. Key terms that need attention in these descriptions, including "sleeve hole," "tongue rod," "protruding nail," "hollow hole," and "curved guide groove," are only for the purpose of facilitating a concise and clear description of this utility model and should not be construed as limiting this utility model.

[0009] like Figure 1-8 As shown, this utility model discloses a multi-functional locking and unlocking device for automotive interiors, including a left tongue rod 1, a right tongue rod 2, an upper tongue rod 3, a bracket 4, a handle 5, a torsion spring 6, and a compression spring 7. The handle 5 includes a clip and a sleeve 5c fixed together. The sleeve 5c has a hole and a curved guide groove 5e. The curved guide groove 5e includes a straight section and a curved section. A pressure arm 5d is provided at the rear of the outer edge of the sleeve 5c. The left tongue rod 1 and the right tongue rod 2 are square shafts (or rectangular square shafts). The left... The tongue rod 1 has a left protruding nail 1a corresponding to the curved guide groove 5e of the buckle sleeve 5c, and the right tongue rod 2 has a right protruding nail 2a corresponding to the curved guide groove 5e of the buckle sleeve 5c. The bracket 4 is C-shaped and has a sleeve corresponding to the sleeve hole of the buckle sleeve 5c of the buckle 5. The sleeve of the bracket 4 has a square hole 4a corresponding to the left tongue rod 1 and the right tongue rod 2, and its end has a step 4c. It also has protruding nail grooves 4b corresponding to the left protruding nail 1a and the right protruding nail 2a respectively. The lower part of the upper tongue rod 3 corresponds to... The outer edge of the buckle 5c has a pressure arm 5d with a hole 3a and an inclined surface 3b at the upper end. The torsion spring 6 is sleeved on the step 4c of the bracket 4. The left and right tongue rods 1 and 2 are respectively installed in the square holes of the tongue rod holes 4a. Their left and right protruding pins 1a and 2a respectively pass through the protruding pin grooves 4b of the bracket 4. The protruding pin grooves 4b of the bracket 4 restrict the left and right tongue rods 1 and 2 to move only axially through the left and right protruding pins 1a and 2a. The buckle 5 is installed through the sleeve hole of the buckle 5c. On the sleeve of the bracket 4, the left protruding nail 1a and the right protruding nail 2a of the protruding nail groove 4b of the bracket 4 respectively pass through, and are both located in the curved guide groove 5e of the buckle 5c. One end of the torsion spring 6 is connected to the bracket 4, and the other end is connected to the buckle 5c of the buckle 5. The lower end of the hole 3a of the upper tongue rod 3 is in contact with the pressure arm 5d of the outer edge of the buckle 5c of the buckle 5. A gap (interval) is left at the upper part of the hole 3a and the bracket 4 is installed. The compression spring 7 abuts against the lower end of the upper tongue rod 3 and the bracket 4.

[0010] This embodiment uses a double-layer glove box in an automobile as an example. The glove box includes two layers: an outer armrest box S1 and an inner internal storage box S2, each of which needs to be opened or closed independently. The multi-functional locking and unlocking device of this utility model is installed on the vehicle body via a bracket 4, with its outer surface flush with the outer edge of the vehicle body for aesthetic purposes. In this embodiment, the handle 5, through its left tongue 1, right tongue 2, and upper tongue 3, can retract and extend corresponding to the tongue holes provided in the armrest box S1 and the internal storage box S2, thereby unlocking or locking the armrest box S1 and the internal storage box S2 respectively, for opening or closing the two layers of the glove box.

[0011] When both the armrest box S1 and the internal storage box S2 are closed as shown in Figure 9, pulling the upper end 5a of the buckle 5 causes the buckle 5 and the buckle sleeve 5c to overcome the torque of the torsion spring 6 and rotate around the bracket 4 in the forward direction. The curved guide groove 5e of the buckle 5 rotates synchronously. The left protruding nail 1a on the left tongue rod 1 and the right protruding nail 2a on the right tongue rod 2 slide inward from their initial positions under the action of the curved section of the curved guide groove 5e, and are restricted by the protruding nail groove 4b of the bracket 4. This causes the left tongue rod 1 and the right tongue rod 2 to axially retract inward within the square hole of the tongue rod hole 4a on the bracket 4, thus unlocking the armrest box S1. Afterward, because the left protruding nail 1a and the right protruding nail 2a are restricted by the protruding nail groove 4b of the bracket 4, when the torsion spring 6 resets, the buckle 5, constrained by the connected left protruding nail 1a and right protruding nail 2a through its curved guide groove 5e, reverses and resets. In the above operation, because there is a pre-reserved travel interval between the upper part of the hole 3a of the upper tongue rod 3 and the rear pressure arm 5d of the buckle 5, when the upper end 5a of the buckle 5 is pulled outward, the rear pressure arm 5d of the buckle 5 will not interfere with or affect the upper tongue rod 3, thereby realizing the function of unlocking the left tongue rod 1 and the right tongue rod 2 on both sides separately. Figure 10 As shown, open the armrest box S1 separately.

[0012] Only when the lower end 5b of the latch 5 is pulled outwards, the latch 5 rotates in the opposite direction around the bracket 4. Its rear pressure arm 5d overcomes the force of the spring 7, pressing down the upper tongue rod 3 and causing it to retract, thus unlocking the internal storage box S2. The straight section of the curved guide groove 5d of the latch 5 is parallel to the end of the buckle sleeve 5c. When the latch 5 rotates in the opposite direction around the bracket 4, the left protruding nail 1a and the right protruding nail 2a remain in the straight section of the curved guide groove 5d. When the lower end 5b of the latch 5 is pulled outwards, the latch 5 rotates around the bracket 4, and the straight section of its curved guide groove 5d does not push the left protruding nail 1a of the left tongue rod 1 and the right protruding nail 2a of the right tongue rod 2 to move. Therefore, the left tongue rod 1 and the right tongue rod 2 do not move, thus achieving the function of unlocking only the upper tongue rod 3. Figure 11 As shown, the internal storage compartment S2 is opened separately. Afterwards, the compression spring 7 returns the upper tongue rod 3 to its original position.

[0013] The above description is merely one embodiment of this utility model. For those skilled in the art, various modifications and variations of this utility model are possible, which will not be elaborated upon here. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection claimed by this utility model.
