[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0026] Please refer to Figures 1 to 4 The present invention provides an acceleration detection switch, comprising: a first contact component 1, at least a part of the first contact component 1 is made of a conductive material, and the first contact component 1 is used to be electrically connected to a first part of an external circuit; a second contact component 2, at least a part of the second contact component 2 is made of a conductive material, and the second contact component 2 is used to be electrically connected to a second part of an external circuit; the second contact component 2 is movably arranged in a direction close to and away from the first contact component 1; the second contact component 2 has an initial position and a contact position; when the second contact component 2 is in the initial position, the second contact component 2 is spaced apart from the first contact component 1 to cut off the first part and the second part of the external circuit; when the second contact component 2 is in the contact position, the second contact component 2 contacts the first contact component 1 to connect the first part and the second part of the external circuit; an elastic component 3, the elastic component 3 contacts the second contact component 2, so that the second contact component 2 is maintained in the initial position under the elastic force of the elastic component 3.
[0027] The acceleration detection switch of the present invention comprises: a first contact component 1, at least a part of which is made of a conductive material, and the first contact component 1 is used to be electrically connected to a first part of an external circuit; a second contact component 2, at least a part of which is made of a conductive material, and the second contact component 2 is used to be electrically connected to a second part of an external circuit; the second contact component 2 is movably arranged in a direction close to and away from the first contact component 1; the second contact component 2 has an initial position and a contact position; when the second contact component 2 is in the initial position, the second contact component 2 is spaced apart from the first contact component 1 to cut off the first part and the second part of the external circuit; when the second contact component 2 is in the contact position, the second contact component 2 contacts the first contact component 1 to connect the first part and the second part of the external circuit; and an elastic component 3, the elastic component 3 contacts the second contact component 2, so that the second contact component 2 is maintained in the initial position under the elastic force of the elastic component 3. When the motion state of the acceleration detection switch changes, that is, the acceleration detection switch has acceleration, under the action of inertia, the second contact member 2 tends to maintain the original motion state, at this time, the second contact member 2 moves relative to the main body of the acceleration detection switch, and the elastic member 3 is deformed by force; when the acceleration reaches a predetermined value, the second contact member 2 overcomes the elastic force of the elastic member 3, thereby reaching the contact position, and realizing the connection between the first part and the second part of the external circuit; when the acceleration is less than the preset value, under the action of the elastic force of the elastic member 3, the second contact member 2 is separated from the first contact member 1; when the acceleration is zero, under the action of the elastic force of the elastic member 3, the second contact member 2 moves to the initial position. In this way, when the acceleration detection switch is installed on a firearm, under the action of the acceleration generated when the firearm is fired, the second contact member 2 contacts the first contact member 1, thereby connecting the external circuit, and realizing one-time triggering and counting, thereby completing the recording of the number of firearm bullets fired using the acceleration when the firearm is fired, and improving the accuracy of the recording of the number of firearm bullets fired.
[0028] In addition, compared with existing mechanical acceleration sensors, piezoelectric acceleration sensors, etc., the acceleration detection switch of the embodiment of the present invention has the advantages of low cost, compact structure, low power consumption, and flexible use. By replacing the elastic component 3 or the second contact component 2, the acceleration detection threshold can be controlled, which is suitable for detection needs under large threshold conditions such as firearm shooting.
[0029] Specifically, at least a portion of the elastic member 3 is made of a conductive material, so that the second contact member 2 is electrically connected to the second part of the external circuit through the elastic member 3. In this way, the second contact member 2 is indirectly connected to the second part of the external circuit through the elastic member 3, which can avoid interference with the movement of the second contact member 2 caused by directly connecting the second contact member 2, thereby ensuring the flexibility of the movement of the second contact member 2.

[0031] Specifically, at least a portion of the elastic component 3 is located between the second contact component 2 and the mounting seat 4; when the second contact component 2 is in the contact position, the elastic component 3 is in a compressed state.
[0032] In a specific implementation, when the second contact member 2 is in the contact position, the elastic member 3 is in a compressed state. In this way, by pre-compressing the elastic member 3, it is ensured that the second contact member 2 can stably stay in the initial position when the acceleration detection switch is not working, thereby ensuring the stability of the structure; and it is also possible to avoid the problem of the second contact member 2 shaking due to deformation of the elastic member 3 after long-term use of the acceleration detection switch, which is conducive to extending the service life of the acceleration detection switch.

[0037] In a specific implementation, the outer wall surface of the second contact component 2 has the same shape as the inner wall of the mounting cavity 51, so that the second contact component 2 is guided by the inner wall of the mounting cavity 51. The housing 5 is connected to the mounting seat 4 by threads; the limiting portion 52 has a limiting surface, and at least part of the limiting surface has the same shape as at least part of the surface of the second contact component 2. The limiting portion 52 is provided with an air vent, which is a through-hole structure and extends to the mounting cavity 51. By providing the air vent, the interference of the air pressure in the mounting cavity 51 on the movement of the second contact component 2 can be avoided, and the flexibility of the movement of the second contact component 2 can be ensured. Optionally, an air vent is provided on the mounting seat 4 to balance the air pressure on both sides of the second contact component 2.
[0038] Specifically, at least a portion of the installation cavity 51 is a cylindrical structure, and at least a portion of the second contact component 2 is a spherical structure; or, the installation cavity 51 is a columnar structure, and the second contact component 2 is a columnar structure.
[0039] Specifically, the housing 5 includes a limiting portion 52, which is spaced apart from the mounting seat 4; when the second contact component 2 is in the initial position, the second contact component 2 contacts the limiting portion 52, so that the second contact component 2 is limited in the initial position through the limiting portion 52; wherein, when the second contact component 2 is in the initial position, the elastic component 3 is in a compressed state.
[0040] Specifically, in order to ensure that the second contact member 2 has a sufficiently large inertia and improve the sensitivity of the acceleration detection switch, the density of the second contact member 2 is in the range of 10 g / cm 3 Up to 20g / cm 3 ; In order to improve the conductivity of the spring, a nickel-plated layer is provided on the outside of the main part of the spring; a gold-plated layer is provided on the outside of the main part of the first terminal 31; a gold-plated layer is provided on the outside of the main part of the second terminal 11 to increase the conductivity and weldability of the first terminal 31 and the second terminal 11; the melting point of the mounting base 4 is not lower than 320°C to avoid deformation of the mounting base 4 due to heat during assembly and use, thereby ensuring the reliability of the acceleration detection switch.
[0041] Preferably, the second contact member 2 is a spherical structure made of a mixture of tungsten and steel, and its density is 17.69 g / cm 3 ; Specifically, the mass of the second contact component 2 is 2g; the main body of the spring is a steel wire; the main body of the first contact component 1 is made of No. 57 copper; the mounting seat is made of PI1003 plastic.

[0042] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

When the motion state of the acceleration detection switch changes, that is, the acceleration detection switch has acceleration, under the action of inertia, the second contact member 2 tends to maintain the original motion state, at this time, the second contact member 2 moves relative to the main body of the acceleration detection switch, and the elastic member 3 is deformed by force; when the acceleration reaches a predetermined value, the second contact member 2 overcomes the elastic force of the elastic member 3, thereby reaching the contact position, and realizing the connection between the first part and the second part of the external circuit; when the acceleration is less than the preset value, under the elastic force of the elastic member 3, the second contact member 2 is separated from the first contact member 1; when the acceleration is zero, under the elastic force of the elastic member 3, the second contact member 2 moves to the initial position.
