[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example 1
[0020] See also Figure 1 and Figure 2A car air conditioning controller comprises: a first shell 1 and a second shell 2, the first shell 1 and the second shell 2 are snap-connected (e.g., the two are connected by snap-fit), a circuit board is arranged inside the first shell 1, a slot 5 (equivalent to a wiring harness interface) is arranged outside the first shell 1, an internal connector of the slot 5 is connected to the circuit board (the internal connector of the slot 5 refers to a contact chip, etc., after the automobile air conditioning wiring harness is inserted into the slot 5, the circuit board is connected to the automobile air conditioning wiring harness, so that the controller can control the automobile air conditioning), a button 4 and a display 3 are arranged outside the second shell 2, and the button 4 and the display 3 are connected to the circuit board through a line.
[0021] See also Figure 1 The inner walls on both sides of the second housing 2 are provided with limit grooves 8, and two limit members 7 (the two limit members 7 are symmetrically arranged) are slidably arranged in the first housing 1. The limit members 7 can move left and right, and the limit members 7 are L-shaped limit blocks; a driving assembly 6 is arranged in the slot 5;
[0022] Among them, see Figure 3 and Figure 4 A mounting groove 62 is provided on the inner wall of the slot 5, and the driving assembly 6 includes a movable rod 63, which is slidably arranged in the inner cavity of the mounting groove 62 (the movable rod 63 can move left and right in the mounting groove 62), and an elastic member 64 (a spring used to limit the movable rod 63 so that it does not move automatically and enables the movable rod 63 to reset after moving) is provided between the movable rod 63 and the mounting groove 62, and the end of the movable rod 63 is connected to the limiting member 7, and a movable rod 61 is slidably arranged in the mounting groove 62, and the movable rod 61 is located on the inner side of the movable rod 63, and one end of the movable rod 61 away from the movable rod 63 extends into the inner cavity of the slot 5, (there are two mounting grooves 62, movable rods 63, elastic members 64 and movable rods 61, and the two movable rods 63 are respectively connected to the two limiting members 7).
[0023] It should be noted that when the wiring harness of the automobile air conditioner is inserted into the slot 5 to connect the controller to the automobile air conditioner, the wiring harness will squeeze the movable rod 61 and push the movable rod 61 into the installation slot 62, so that it contacts the movable rod 63 and moves with the movable rod 63; when the movable rod 63 moves, the limit member 7 will be inserted into the limit slot 8 to lock the first shell 1 and the second shell 2; when the wiring harness is moved out of the slot 5, the squeezing of the movable rod 61 disappears, so that the force on the movable rod 63 disappears, and under the action of the elastic member 64, the movable rod 63 is reset, so that the limit member 7 is also moved out of the limit slot 8, and the restriction between the first shell 1 and the second shell 2 is released. At this time, the first shell 1 and the second shell 2 can be disassembled.
[0024] In this embodiment, as a further optimized solution, please refer to Figure 5 and Figure 6A rotating shaft is rotatably arranged in the mounting groove 62, and a magnetic block 65 is arranged on the rotating shaft. The magnetic block 65 is located on the inner side of the movable rod 63 (according to Figure 6 In the direction shown, the magnetic block 65 is located on the right side of the movable rod 63), a magnetic block is provided on the side of the movable rod 63 away from the limiting member 7, and the magnetic poles of the magnetic block and the magnetic block 65 on the side close to each other are opposite, a gear 66 is fixedly sleeved on the outer wall of the rotating shaft, and a rack 67 is provided on the movable rod 61, and the rack 67 is meshed with the gear 66; when the movable rod 61 is squeezed by the wire harness and moves, the rack 67 moves, driving the gear 66 and the magnetic block 65 to rotate, and the magnetic pole on the other side of the magnetic block 65 is opposite to the magnetic block, so that the magnetic poles of the magnetic block 65 and the side close to each other are the same, at this time, a repulsive force is generated between the two, which is used to push the movable rod 63 to move and insert the limiting member 7 into the limiting groove 8; the limiting member 7 is driven to move by the magnetic repulsion between the magnetic block 65 and the magnetic block, thereby ensuring the movement amplitude of the limiting member 7 and ensuring that the limiting member 7 is inserted into the limiting groove 8.
[0025] In this embodiment, as a further optimized solution, please refer to Figure 4 When the wiring harness is inserted into the slot 5, the area where the moving rod 61 contacts the wiring harness is not an arcuate surface, so that the moving rod 61 will not hinder the wiring harness from being inserted into the slot 5.
[0026] In this embodiment, as a further optimized solution, please refer to Figure 3 The key 4 includes a key body 41 and a key cap 42 detachably mounted on the key body 41 (the key cap 42 and the key body 41 are connected by snap fastenings); the key cap 42 can be removed from the key body 41 for replacement of the key cap 42 .
[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
