According to the structure form, the switch and the groove of the prior art are oriented in different directions, which means that multiple clamping is required. The process cycle is long, and the production efficiency is low;And the switch is distributed in the lock body, and the corresponding trigger structure occupies a large amount of structure space. UTILITY MODEL CONTENTS

[0003] The utility model discloses a kind of integrations of microswitchs to solve the problem that contact switch and groove of prior art are oriented in different directions, multiple clamping is required, and corresponding trigger structure occupies a large amount of structure space.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0007] Preferably, the number of the contact switch is at least three.

[0029] An integrated micro switch includes a housing 1, as shown in the reference. Figure 1 At least three contact switches are installed on the housing 1. The contact switches are marked as S in the figure. The contact switches are installed on the same side of the housing 1. The contact switches are vertically arranged at the outer end of the housing 1, and the projection of the contact switches relative to the outer end of the housing 1 is offset.

[0030] It should be noted that housing 1 is also commonly referred to as EKT or ECC. It integrates microswitches, wire terminals, motor terminals, plugs and other structures, and is used between the door lock and the body circuit to provide feedback on the internal status of the door lock to the body, or to input current to the door lock to drive the motor and other actions.

[0031] The contact switches are mounted on the same side of the housing, concentrated in the same area, along... Figure 1 and Figure 2 The switches are installed in the X-direction, with all contact switches projected along this direction and not overlapping. This simplifies the EKT switch installation process, allowing all contact switches to be installed in a single clamping operation, eliminating the need for rotation or flipping, thus improving efficiency.

[0032] Contact switches used in car door locks typically employ processes including, but not limited to, sealing and potting to achieve physical isolation from the external environment of the housing 1. Preferably, such as... Figure 2 After the intermediate contact switch is installed, a potting groove is provided on the housing 1 at the output terminal of the contact switch. For example... Figure 3As shown, the liquid gel is poured into the filling groove. Figure 3 The gel-like substance is denoted as P in the attached diagram. It is then cured by natural curing, heat curing, or ultraviolet light curing to become a cross-linked body or solid, thereby isolating the switch terminals, internal circuits, and the outside of the housing, providing electrical insulation, corrosion resistance, and mechanical connection properties.

[0033] It should be added that the encapsulation process of the contact switch with the adhesive has requirements on the position and orientation of the housing 1. Typically, the potting groove must be kept upwards to facilitate adhesive injection, expel air, and prevent uncured adhesive from flowing out. However, in existing technologies, such as the contact switch and potting groove in application number "CN113789998A" facing different directions, multiple clamping operations are required to meet the positional requirements of the above process, resulting in a long process cycle and low production efficiency. This embodiment follows... Figure 1 and Figure 2 The switch set in the X direction can be moved along the [axis] in a single clamping operation. Figure 1 and Figure 2 The X-direction process enables both dispensing and curing in one step, improving productivity.

[0034] Furthermore, according to the requirements of the door lock structure, the number of contact switches is at least three. The contact switches located at the two ends are contact switch S1 and contact switch S2, respectively, and each uses a corresponding rotary cam 11 and rotary cam 21 structure located at the end to trigger its operation. Figure 4 and Figure 5 As shown, typical drive structures include, but are not limited to, door lock plates, pawls, and other rotating structures. For specific structures, refer to application number "CN112177453A" in the prior art. It should be clarified that the cam structure is a rotary cam, and the outer wall of the rotary cam includes a contact surface and a clearance surface. The inner diameter of the clearance surface is smaller than the inner diameter of the contact surface. However, this structure is not limited to rotary cam structures at all ends; triggering its operation should fall within the protection scope of this patent.

[0035] When the number of contact switches is at least four, the contact switches located in the middle are arranged side by side, and the contact directions of adjacent contact switches are opposite. In this embodiment, taking four contact switches as an example, the contact switches located in the middle are contact switch S3 and contact switch S4. The contacts of contact switches S3 and S4 are arranged perpendicular to the outer wall of the housing, and their operation is triggered by a reciprocating convex strip structure that slides parallel to and close to the end of the contact switch. (Refer to...) Figure 6 and Figure 7Contact switch S3 and sliding protrusion 31, contact switch S4 and sliding protrusion 41. In particular, depending on the door lock function requirements, there may be only contact switch S3, only contact switch S4, or both contact switches S3 and S4 may exist simultaneously.

[0036] It should be noted that the reciprocating sliding convex structure is a slide bar, specifically sliding convex bar 31 and sliding convex bar 41. The slide bar slides linearly within the housing, and it has an abutting groove. The abutting groove includes an abutting surface B and a relief surface B, with the depth of the relief surface B being greater than the depth of the abutting surface B. This structure provides the possibility of a mechanical connection between the two ends of sliding convex bar 31 and sliding convex bar 41, i.e., along... Figure 6 and Figure 7 Mechanical movement in the Z-direction is transmitted from the upper end to the lower end, or vice versa, thus forming a certain pull rod or push rod structure. The slide bar is driven by an actuator, which can be either a motor-driven worm gear or a manual pull rod.

[0037] If two contact switches S3 and S4 located in the middle are present simultaneously, and the main bodies of contact switches S3 and S4 are side by side, while the switch contacts of contact switches S3 and S4 are staggered and symmetrically arranged facing the left and right sides of housing 1 respectively, then correspondingly, their respective sliding protrusions 31 and 41 are located on both sides of housing 1, triggering contact switches S3 and S4 to operate respectively. (Refer to...) Figure 6 and Figure 7 Contact switches S3 and S4 face to the sides, and sliding protrusions 31 and 41 are located on the left and right sides of housing 1 respectively. Driven by the actuator, sliding protrusions 31 and 41 slide independently along the Z-direction to trigger the switch action. Specifically, their movements can be independent of each other. This structural design achieves a perpendicularity to... Figure 6 and Figure 7 The cross-section in the Z-direction requires the least space, thus compressing the volume of the entire structure and optimizing costs.

[0038] Based on the specific sliding protrusion 31, sliding protrusion 41, rotary cam 11, and rotary cam 21, contact switches S1, S2, S3, and S4 can be designed to be in a free state under normal conditions, in which the contacts of the contact switches are triggered by compression; or they can be designed to be in a compressed state under normal conditions, in which the contacts of the contact switches are triggered when they are not compressed.

[0039] The housing 1 has an internal electrical conductor structure, such as a copper wire, that is connected to the contact switch. Its purpose is to output the signal of the contact switch to the outside of the housing.

[0040] The contact switches use a structure that shares at least some conductors, as shown in the reference. Figure 8 To achieve cost savings and structural simplification, the specific electrical conductor structure includes a common terminal and a shunt terminal. The common terminal is electrically connected to multiple contact switches, and the shunt terminal is electrically connected to a single contact switch. (Refer to...) Figure 9 The common ground wire 2 structure; optionally, the contact switch can be connected via a resistor to achieve the purpose of multiplexing terminals. For example... Figure 10 The resistors R1 and R2 are connected in series with a switch to enable the reuse of terminals, and the above design saves costs.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
