DETAILED DESCRIPTION

[0018] like Figures 1 to 2As shown, an angle-adaptive formation probe includes a probe body 1 and a fixed base. The fixed base is used to connect to a formation device, specifically, the fixed base is connected to a needle bed of the formation device. The fixed base is provided with an angle adjustment mechanism for adjusting the angle of the probe body 1. The angle adjustment mechanism includes an external joint 5, an internal joint 6, and a conical spring 9. The external joint 5 is open at both ends and fits over the external side of the internal joint 6. The internal joint 6 is a sphere or a spherical segment structure. Specifically, the internal joint 6 is a sphere or a spherical segment structure with both ends cut off by planes. The external joint 5 has an inner spherical surface that matches the outer spherical surface of the internal joint 6. The internal joint 6 is rotatable relative to the external joint 5. The internal joint 6 fits over the external side of the probe body 1. A probe head is provided at one end of the probe body 1. The probe body 1 also has a stop 10 between the probe head and the internal joint 6. The conical spring 9 fits over the external side of the probe body 1. The small-diameter end of the conical spring 9 is connected to the stop 10, and the large-diameter end of the conical spring 9 is connected to the external joint 5. The present invention makes the probe body 1 movably connected to the fixing seat by setting the external joint 5 and the internal joint 6, and realizes the adjustment of the angle of the probe body 1 by rotating the internal joint 6 inside the external joint 5. When the formation probe is installed on the needle bed, the large diameter end of the conical spring 9 is pressed against the external joint 5, and the small diameter end is pressed against the limit platform 10, so that the probe body 1 is naturally parallel with the conical spring 9 without being affected by external forces. When the needle bed is pressed down, when the angle of the battery is tilted, the probe body 1 can drive the internal joint 6 to rotate relative to the external joint 5, and adapt to the tilt angle to avoid poor contact between the probe body 1 and the battery pole, so that the probe body 1 is in full contact with the battery, ensuring that the contact resistance between the probe body 1 and the battery pole is smaller, and reducing heat loss.

[0019] Preferably, the inner joint 6 and the outer joint 5 are made of wear-resistant material.

[0020] A plurality of balls 7 are provided between the inner spherical surface of the outer joint 5 and the outer spherical surface of the inner joint 6. The balls 7 enable the inner joint 6 and the outer joint 5 to rotate, thereby reducing friction between the inner joint 6 and the outer joint 5 and preventing friction-generated debris from affecting the measurement of the probe body 1. Preferably, the balls 7 are made of a non-metallic wear-resistant material, such as Teflon.

[0021] The inner spherical surface of the external joint 5 is provided with multiple upper ball channels, and the outer spherical surface of the internal joint 6 is provided with multiple lower ball channels 12. The upper ball channels and the lower ball channels 12 constitute a ball channel. Each ball channel is provided with at least one ball 7. The ball 7 is limited by the ball channel to increase the stability of the connection between the external joint 5 and the internal joint 6.

[0022] A retainer 8 is provided between the outer joint 5 and the inner joint 6. The retainer 8 has a plurality of retaining holes 13 for receiving the balls 7. Specifically, the inner and outer surfaces of the retainer 8 match the outer and inner surfaces of the inner joint 6 and 5, respectively. The number of retaining holes 13 matches the number of ball tracks. These retaining holes 13 retain the balls 7 circumferentially and axially, further enhancing the stability of the connection between the outer joint 5 and the inner joint 6.

[0023] The inner joint 6 is provided with an installation channel, in which a first gear tooth is provided. The probe body 1 is provided with a second gear tooth 14. The first gear tooth and the second gear tooth 14 are meshed with each other. The connection between the inner joint 6 and the probe body 1 is achieved through the meshing of the first gear tooth and the second gear tooth 14.

[0024] The first gear teeth and the second gear teeth 14 are in interference engagement, and the stability of the connection between the inner joint 6 and the probe body 1 is increased by the interference engagement.

[0025] The fixing base includes a side wall 3 and an upper cover 2 and a lower cover 4 provided at both ends of the side wall 3. It should be noted that the present disclosure does not limit the connection method between the side wall 3 and the upper cover 2 and the lower cover 4. The connection method can be adhesive, welding, threaded connection, or clamping. The side wall 3 and the lower cover 4 can also be integrally formed. The upper cover 2 and the lower cover 4 are respectively provided with openings. The side wall 3, the upper cover 2 and the lower cover 4 form a receiving space for accommodating the angle adjustment mechanism. At the same time, the openings of the upper cover 2 and the lower cover 4 also leave space for wiring and rotation of the probe body 1.

[0026] The outer diameter of the external joint 5 matches the inner diameter of the side wall 3. The external joint 5 can be fixedly connected to the fixing seat or flexibly connected. When the external joint 5 is flexibly connected to the fixing seat, the aperture of the opening is smaller than the outer diameter of the external joint 5. A limit spring 11 is also provided between the external joint 5 and the upper cover 2. Specifically, one end of the limit spring 11 is connected to the external joint 5 and the other end is connected to the upper cover 2. The limit spring 11 presses the external joint 5 against the lower cover 4 of the fixing seat. When the needle bed is pressed down, the limit spring 11 can act as a buffer, ensuring that there is buffer space for the probe body 1.
