[0035] like Figure 1-4 As shown, an embodiment of the present application provides a connection structure, including a locking member 23, a first component 1 and a second component 2, wherein the first component 1 is provided with a first guide protrusion 11 and a second guide protrusion 12 spaced apart and a locking groove 13 located between the first guide protrusion 11 and the second guide protrusion 12; the second component 2 is provided with a first guide groove 21 adapted to the first guide protrusion 11, and a second guide groove 22 adapted to the second guide protrusion 12, the first guide groove 21 being connected to the second guide groove 22; the locking member 23 is installed in the second guide groove 22; the locking member 23 is locked in the locking groove 13.

[0036] It can be understood that the first component 1 can be a metal plate, the second component 2 can be a plastic part, the center line of the first guide protrusion 11 coincides with the center line of the second guide protrusion 12, the first guide protrusion 11 and the second guide protrusion 12 can be guide rails, the first guide groove 21 and the second guide groove 22 can be slide grooves that cooperate with the guide rails, the locking groove 13 can be a groove, a locking groove, etc. between the guide rails arranged at intervals, and the locking member 23 can be an elastic locking piece that cooperates with the groove, a locking block adapted to the lock groove, etc.

[0037] Specifically, the mating steps of the first component 1 and the second component 2 are as follows: the second guide protrusion 12 first enters the first guide groove 21, then the second guide protrusion 12 slides along the first guide groove 21 and inserts into the second guide groove 22. At this time, the locking member 23 is locked to the locking groove 13, and the first wire protrusion 11 is inserted into the first guide groove 21, thereby locking and installing the second component 2 on the first component 1. In the present invention, the first guide protrusion 11 and the second guide protrusion 12 not only serve as guides, but the locking groove 13 between the first guide protrusion 11 and the second guide protrusion 12 also serves as a locking function. Therefore, the connection structure not only serves as a guide when locked to each other, but also ensures the stability and accuracy of the locking of the first component 1 and the second component 2. In addition, the connection structure has a simple structure, low manufacturing cost, and simple mating operation.

[0038] like Figure 1-5 As shown, the locking member 23 includes a locking seat 231, a guide block 232 provided with a guide surface, and a spring 233 connected to the locking seat 231, and the end of the locking seat 231 away from the spring 233 is connected to the guide block 232, the guide block 232 is installed in the first guide groove 21, and the locking seat 231 is installed in the second guide groove 22; the guide block 232 is used to slide the second guide protrusion 12 over the locking seat 231 to the second guide groove 22.

[0039] It can be understood that the locking seat 231 is a rectangular block, the guide block 232 with a guide surface can be a right-angled triangle block, the top surface of the right-angled triangle block is the guide surface, and the guide surface can be a slope, etc. The spring piece 233 can be a locking piece with a certain elasticity.

[0040] Specifically, during the interlocking process between the first component 1 and the second component 2, the second guide protrusion 12 slides along the first guide groove 21 toward the second guide groove 22. The second guide protrusion 12 slides along the guide surface of the guide block 232 onto the locking seat 231 and the elastic piece 233. After the second guide protrusion 12 passes over the elastic piece 233, it slides into the second guide groove 22. After the elastic piece 233 disengages from the second guide protrusion 12, it recovers its deformation and locks into the locking groove 13. In this embodiment, the design of the guide surface on the guide block 232 allows the second guide protrusion 12 to pass over the locking piece 23 and slide into the second guide groove 22, ensuring smooth docking between the first component 1 and the second component 2. In addition, the locking piece 23 has a simple structure and low manufacturing cost.

[0041] like Figure 1-5 As shown, the first guide protrusion 11 and the second guide protrusion 12 both extend along the first direction; the first guide protrusion 11 includes a first protrusion 111 and a second protrusion 112 connected to the first protrusion 111; along a cross section perpendicular to the first direction, the width of the first protrusion 111 is greater than the width of the second protrusion 112; the first guide groove 21 includes a first groove 211 adapted to the first protrusion 111 and a second groove 212 adapted to the second protrusion 112; along a cross section perpendicular to the first direction, the width of the first groove 211 is greater than the width of the second groove 212; the first protrusion 111 is inserted into the first groove 211, and the second protrusion 112 is inserted into the second groove 212, and the end of the elastic piece 233 away from the locking seat 231 abuts against the end of the second guide protrusion 12 close to the locking groove 13, and the end of the locking seat 231 away from the elastic piece 233 abuts against the end of the first guide protrusion 11 close to the locking groove 13.

[0042] It can be understood that the first protrusion 111 is connected to the top surface of the second protrusion 112, so that the first guide protrusion 11 presents a T-shaped guide rail shape, etc.; the first groove 211 is connected to the top of the second groove 212, so that the first guide groove 21 presents a T-shaped slide groove that cooperates with the T-shaped guide rail.

[0043] Specifically, when the first guide protrusion 11 is inserted into the second guide groove 21, the first protrusion 111 slides into and is inserted into the first groove 211, and the second protrusion 112 slides into and is inserted into the second groove 212. Since the width of the first protrusion 111 is greater than the width of the second protrusion 112, the first guide protrusion 11 can only slide along the first direction in the first guide groove 21, and cannot move along the second direction perpendicular to the first direction.

[0044] When locked in the locking groove 13, the end of the spring piece 233 away from the locking seat 231 abuts against the end of the second guide protrusion 12 near the locking groove 13, and the end of the locking seat 231 away from the spring piece 233 abuts against the end of the first guide protrusion 11 near the locking groove 13, thereby limiting movement in the first direction between the first component 1 and the second component 2. In summary, the first guide protrusion 11 inserted into the first guide groove 21 can limit movement in the second direction between the first component 1 and the second component 2; the locking member 23 locked in the locking groove 13 can limit movement in the first direction between the first component 1 and the second component 2, thereby locking and mounting the second component 2 on the first component 1, ensuring stability and precision when locking the first component 1 and the second component 2.

[0045] like Figure 1-5 As shown, along the cross section perpendicular to the first direction, the width of the second guide protrusion 12 is smaller than the width of the second groove 212 .

[0046] It can be understood that the first guide protrusion 11 can be a T-shaped guide rail, the second protrusion 112 is a straight arm, the first protrusion 111 is the horizontal arm of the T-shaped guide rail, the first guide groove 21 can be a T-shaped slide groove that cooperates with the T-shaped guide rail, the second groove 212 is a vertical groove that cooperates with the vertical arm of the T-shaped guide rail, the first groove 211 is a horizontal groove that cooperates with the horizontal arm of the T-shaped guide rail, and the second guide protrusion 12 can be a rectangular block.

[0047] Specifically, along the cross section perpendicular to the first direction, the width of the second guide protrusion 12 is smaller than the width of the second groove 212. During the assembly process of the first component 1 and the second component 2, the second guide protrusion 12 needs to slide through the first guide groove 21 first. When the second guide protrusion 12 slides from the first guide groove 21, the second guide protrusion 12 and the second groove 212 are clearance-fitted, so that the second component 2 is connected to the first component 1 for preliminary calibration. The second guide protrusion 12 slides over the locking piece 23 into the second guide groove 22 until the first guide protrusion 11 is slidably inserted into the first guide groove 21, the second guide protrusion 12 is slidably inserted into the second guide groove 22, and the locking piece 23 is locked in the locking groove 13, thereby locking the second component 2 and installing it on the first component 1.

[0048] like Figure 1-5 As shown, the distance between the elastic piece 233 and the bottom wall of the second guide groove 22 gradually increases from the end close to the locking seat 231 to the end away from the locking seat 231 .

[0049] It can be understood that the spring piece 233 can be an elastic locking piece, which is obliquely inserted into the locking seat 231.

[0050] Specifically, during the assembly of the first component 1 and the second component 2, the second guide protrusion 12 slides through the first guide groove 21, and the second guide protrusion 12 slides into the second guide groove 22 along the guide surface of the guide block 232, over the locking seat 231, and the second guide protrusion 12 causes the spring piece 233 to deform, and along the end close to the locking seat 231 toward the end away from the locking seat 231, the distance between the spring piece 233 and the bottom wall of the second guide groove 22 gradually increases. When the second component 2 moves on the first component 1, the second guide protrusion 12 causes the deformation of the spring piece 233 to increase until the first guide protrusion 11 is inserted into the first guide groove 21 and the second guide protrusion 12 is inserted into the second guide groove 22, and the spring piece 233 slides into the locking groove 13. The spring piece 233 recovers part or all of its deformation, and the locking member 23 is locked in the locking groove 13, thereby locking and installing the second component 2 on the first component 1.

[0051] like Figure 1-5 As shown, the first component 1 includes a first panel 14, and the first guide protrusion 11 and the second guide protrusion 12 are both protrudingly arranged on the first panel 14; the distance between the first guide protrusion 11 and the first panel 14 is greater than the distance between the second guide protrusion 12 and the first panel 14.

[0052] It can be understood that the first component 1 can be a metal plate, the first panel 14 is a panel of the metal plate close to the side of the second component 2, the first guide protrusion 11 can be a protrusion set on the first panel 14, and the second guide protrusion 12 can be a T-shaped protrusion set on the first panel 14, and the distance between the protrusion and the first panel 14 is smaller than the distance between the T-shaped protrusion and the first panel 14.

[0053] Specifically, during the assembly of the first component 1 and the second component 2, the first guide groove 21 cooperates with the first guide protrusion 11. Since the distance between the first guide protrusion 11 and the first panel 14 is greater than the distance between the second guide protrusion 12 and the first panel 14, the first guide groove 21 can be clearance-fitted with the second guide protrusion 12, so that the first guide groove 21 of the second component 2 first moves along the second guide protrusion 12 on the first component 1. The first guide groove 21 and the second guide protrusion 12 are clearance-fitted, which can simplify the connection and assembly of the first component 1 and the second component 2 and further simplify the connection structure.

[0054] like Figure 1-5 As shown, the second component 2 includes a second panel 24 , the first guide groove 21 and the second guide groove 22 are both provided on the second panel 24 , and when the locking member 23 is locked in the locking groove 13 , the first panel 14 fits with the second panel 24 .

[0055] It can be understood that the first component 1 can be a metal plate, the first panel 14 is a panel of the metal plate close to the side of the second component 2, the first component 1 can be a plastic part, the second panel is a panel of the plastic part close to the side of the first component 1, and the distance between the first guide protrusion 11 and the first panel 14 is adapted to the distance between the first guide groove 21 and the second panel 24.

[0056] Specifically, the second component 2 moves on the first component 1 through the first guide protrusion 11 that cooperates with the first guide groove 21 and the second guide protrusion 12 that cooperates with the second guide groove 22 until the first guide protrusion 11 is slidably inserted into the first guide groove 21, the second guide protrusion 12 is slidably inserted into the second guide groove 22, and the locking member 23 is locked in the locking groove 13. The distance between the first guide protrusion 11 and the first panel 14 is equal to the distance between the first guide groove 21 and the second panel 24, so that when the first component 1 and the second component 2 are locked, the first panel 14 and the second panel 24 are fitted together. During assembly, the first panel 14 of the first component 1 can be directly fitted with the second panel 24 of the second component 2, and the second component 2 can be moved on the first component 1 to complete the connection between the first component 1 and the second component 2, so that the connection structure between the first component 1 and the second component 2 can be stabilized.

[0057] like Figure 1-5 As shown, the first component 1 is further provided with an entrance groove 25 connecting the first guide groove 21 to the end away from the second guide groove 22; the width of the entrance groove 25 gradually increases from the end close to the first guide groove 21 to the end away from the first guide groove 21.

[0058] It can be understood that the inlet slot 25 can be a trumpet-shaped structure, a gradually expanding structure, etc.

[0059] Specifically, the second component 2 first passes through the entrance groove 25 in the first guide groove 21 and is aligned with the second guide protrusion 12 in the first component 1. The second guide protrusion 12 slides into the first guide groove 21 along the entrance groove 25. Due to the shape of the entrance groove 25, the entrance groove 25 is easier to dock with the second guide protrusion 12, so that the first component 1 and the second component 2 complete the preliminary connection, and the second guide protrusion 12 is slidably connected to the first guide groove 21, so that the second component 2 moves on the first component 1 through the first guide protrusion 11 that cooperates with the first guide groove 21 and the second guide protrusion 12 that cooperates with the second guide groove 22, so that the connection and assembly operation of the first component 1 and the second component 2 is simple.
