Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a probe structure. Background Art

[0002] A battery is an energy device that is usually used to provide power to electronic devices. There are many types of batteries, such as lithium batteries, nickel-cadmium batteries, lead-acid batteries, etc. The basic principle of a battery is to generate electrical energy through chemical reactions.

[0003] A probe is a tool used to test or measure electrical or electronic properties. The probe is usually made of metal, with one end in a needle shape and the other end usually connected to a test instrument. During the test, one end of the probe touches the object being tested, and the other end reads the electrical parameters, such as voltage, current, resistance, etc., through the test instrument.

[0004] The combination of a battery and a probe is usually used to measure the performance parameters of the battery, such as the battery's voltage, current, internal resistance, etc. By connecting the two poles of the battery with a probe, the battery's voltage and current can be measured to evaluate the battery's performance and status.

[0005] Based on this, Chinese patent CN215984929U discloses a test probe, which includes a needle head and a needle rod connected to the needle head. Along the axial direction of the needle rod, the needle rod is divided into at least two separate parts; a first cavity is provided inside the needle head, and a second cavity is provided inside the needle rod. The first cavity and / or the second cavity are used to place a sensor. The test probe can be used to detect the temperature change inside the battery during the acupuncture process.

[0006] However, in the existing automated large-scale production equipment, the contact method between the probe and the battery is mostly sharp-tooth point contact; its characteristic is that after the two are in contact, the relative position of the probe and the battery will not move. At this time, if the contact surface of the probe and the battery is not parallel, there will be a defect that some sharp-tooth points cannot contact, thereby affecting the working efficiency of the equipment; over time, these contacting sharp-tooth points are overloaded for a long time and are prone to burnout. Specifically, after the probe contacts the battery, the relative position between the two will not move, the oxide film cannot be pierced, and a good contact effect between the two cannot be ensured; moreover, after long-term use, the contact points of some sharp-tooth points are prone to overload and burnout, thereby affecting the service life of the probe. In addition, since the contact method between the probe and the battery is sharp-tooth point contact, and some battery pole covers are made of soft materials, the pole cover of the battery is easily damaged, leaving sharp-tooth marks; ultimately affecting the service life of the battery. Utility Model Content

[0007] Based on this, it is necessary to provide a probe structure to address the technical issues of how to improve the contact effect between the probe and the battery, increase the service life of the equipment, and protect the battery as much as possible.

[0008] A probe structure comprises: a probe rod structure, an elastic telescopic structure, a probe guide structure and an end fixing structure; the elastic telescopic structure is movably arranged on the probe rod structure, and the elastic telescopic structure connects the probe guide structure and the probe rod structure respectively; the probe guide structure is movably connected to the probe rod structure, the end fixing structure is arranged at the end of the probe rod structure, and the end fixing structure limits the probe guide structure on the probe rod structure.

[0009] Furthermore, the probe rod structure comprises a contact portion, a rod portion, a plurality of guide grooves and a connecting end portion.

[0010] Furthermore, the contact portion is arranged at one end of the rod body, a plurality of the guide grooves are evenly coiled and arranged on the rod body, and the connecting end portion is arranged at the other end of the rod body relative to the contact portion.

[0011] Furthermore, a plurality of the guide grooves are arranged between the contact portion and the connecting end portion.

[0012] Furthermore, the probe guiding structure has a first guiding connection portion, a second guiding connection portion, a plurality of embedding grooves and a plurality of ball structures.

[0013] Furthermore, the first guide connection portion is connected to the second guide connection portion, and the first guide connection portion and the second guide connection portion are movably sleeved on the rod body portion.

[0014] Furthermore, a plurality of the inlay grooves are evenly distributed between the first guiding connection portion and the second guiding connection portion.

[0015] Furthermore, each of the inlay grooves is disposed between the rod body and the first guide connection portion; or each of the inlay grooves is disposed between the rod body and the second guide connection portion.

[0016] Furthermore, each of the ball structures is movably disposed in a corresponding embedding groove.

[0017] Furthermore, each of the ball structures is movably connected to a corresponding guide groove.

[0018] In summary, the utility model has a probe structure that is respectively provided with a probe rod structure, an elastic telescopic structure, a probe guide structure and an end fixing structure; the elastic telescopic structure is movably arranged on the probe rod structure, and the elastic telescopic structure is respectively connected to the probe guide structure and the probe rod structure; the probe guide structure is movably connected to the probe rod structure, and the end fixing structure is arranged at the end of the probe rod structure, and the end fixing structure limits the probe guide structure on the probe rod structure. In the technical scheme disclosed by the prior art, the contact mode between the probe and the battery is mostly point-to-surface contact. In this mode, the relative position of the probe and the battery after contact will not change, and it is impossible to ensure that a good contact effect can be achieved between the two; thus, it may affect the working efficiency of the equipment and increase invalid working time and cost. In the technical scheme disclosed by the utility model, the rotation action of the probe rod body is used to ensure the parallelism between the probe end face and the battery contact surface, and increase the contact area between the two. At the same time, the rotation action provided can effectively destroy the insulation of the contact surface and further reduce the contact impedance. In addition, when the probe is pressed down and rotated, the contact process between the probe and the battery cap will undergo a dynamic rotation process, making the contact surface of the probe and the battery more parallel; thereby, the current carrying capacity of the probe is increased; and the contact surface of the battery is protected so that it does not leave an indentation. Therefore, the probe structure of the utility model solves the technical problems of how to improve the contact effect between the probe and the battery, increase the service life of the equipment, and protect the battery as much as possible.

[0031] Please also read Figures 1 to 6 The utility model provides a probe structure comprising: a probe rod body structure 1, an elastic telescopic structure 2, a probe guide structure 3 and an end fixing structure 4; the elastic telescopic structure 2 is movably arranged on the probe rod body structure 1, and the elastic telescopic structure 2 is respectively connected to the probe guide structure 3 and the probe rod body structure 1; the probe guide structure 3 is movably connected to the probe rod body structure 1, and the end fixing structure 4 is arranged at the end of the probe rod body structure 1, and the end fixing structure 4 limits the probe guide structure 3 to be located on the probe rod body structure 1.

[0032] Specifically, when a probe structure of the utility model is in operation, the end face of the probe rod structure 1 at the other end provided with respect to the end fixing structure 4 abuts against the contact surface of a battery or other device; and when the contact surface of a battery or other device moves up, the probe rod structure 1 and the probe guide structure 3 cooperate with each other so that the probe rod structure 1 follows the contact surface of the battery and moves up and rotates around the guidance of the probe guide structure 3; the elastic telescopic structure 2 is connected between the probe rod structure 1 and the probe guide structure 3, and when the probe rod structure 1 rotates and moves up, the elastic telescopic structure 2 is compressed to shorten the relative distance between the probe rod structure 1 and the dry guide pin bone 3. In this way, the probe rod structure 1 can adapt to the uneven contact surface of a battery or other device, that is, the relative parallelism between the probe rod structure 1 and the contact surface is automatically adjusted through the process of the probe rod structure 1 rotating and moving up, thereby ensuring a better contact effect between the probe and the conductive contact of the battery.

[0033] Furthermore, the probe rod structure 1 has a contact portion 101, a rod portion 102, a plurality of guide grooves 103 and a connecting end portion 104; the contact portion 101 is arranged at one end of the rod portion 102, a plurality of the guide grooves 103 are evenly coiled and arranged on the rod portion 102, and the connecting end portion 104 is arranged at the other end of the rod portion 102 relative to the contact portion 101; a plurality of the guide grooves 103 are all arranged between the contact portion 101 and the connecting end portion 104. Specifically, the contact portion 101 is mainly used to respectively conduct the contacts connecting the battery and the rod portion 102, so that the probe rod structure 1 can be connected to the battery. Moreover, the portion of the contact portion 101 connected to the battery contact can also be a blunt surface or a planar structure, thereby avoiding damage to the contact plane at the battery contact. The rod body 102 is a connecting structure, and the contact part 101 and the connecting end 104 are respectively arranged at the two ends thereof, and the elastic telescopic structure 2 is movably sleeved on its periphery, and a plurality of guide grooves 103 are evenly spaced near the connecting end 104, so that each guide groove 103 is coiled on the rod body 102. More specifically, the probe rod body structure 1 can be made of metal material, or a conductive material; it is easy to know that the elastic telescopic structure 2, the probe guide structure 3 and the end fixing structure 4 can also be made of conductive materials, preferably metal materials, such as copper or copper alloys.

[0034] Furthermore, the elastic telescopic structure 2 can be a spring or a material with elastic telescopic properties, for example, a sleeve or spring-like structure made of a material with elastic recovery ability such as silicone or rubber, and is sleeved on the periphery of the rod body 102, with its two ends respectively abutting the contact portion 101 and the probe guide structure 3.

[0035] Furthermore, the probe guiding structure 3 has a first guiding connection part 301, a second guiding connection part 302, a plurality of inlay grooves 303 and a plurality of ball structures 304; the first guiding connection part 301 is connected to the second guiding connection part 302, and the first guiding connection part 301 and the second guiding connection part 302 are movably mounted on the rod body part 102; a plurality of inlay grooves 303 are evenly distributed between the first guiding connection part 301 and the second guiding connection part 302, and each of the inlay grooves 303 is arranged between the rod body part 102 and the first guiding connection part 301 or the second guiding connection part 302; each of the ball structures 304 is correspondingly movably arranged in one of the inlay grooves 303, and each of the ball structures 304 is correspondingly movably connected to one of the guide grooves 103. Specifically, a plurality of connecting bolts 301a may be provided between the first guide connection portion 301 and the second guide connection portion 302; each of the connecting bolts 301a connects the first guide connection portion 301 with the second guide connection portion 302; thereby, the first guide connection portion 301 and the second guide connection portion 302 are fixedly connected as a whole; and the inlay groove 303 is provided between the first guide connection portion 301 and the second guide connection portion 302, and the ball structure 304 is limitedly connected therein, and each Each of the ball structures 304 can roll in the corresponding embedding groove 303; thus, when the probe rod structure 1 moves relative to the probe guide structure 3, the ball structure 304 in the embedding groove 303 can move along the corresponding guide groove 103, and the guide groove 103 is coiled on the rod portion 102, so that the probe rod structure 1 can be rotated upward when moving upward, so as to level the contact portion 101 on the uneven external battery contact point. When the contact portion 101 leaves the external battery contact point, the elastic telescopic structure 2 restores the deformation to push the probe rod structure 1 to restore its initial position.

[0036] Furthermore, the end fixing structure 4 can be a connector such as a nut, and is fixed to the end of the rod body 102 through a threaded connection to limit the probe guiding structure 3 between the rod body 102 and the elastic telescopic structure 2.

In this mode, the relative position of the probe and the battery after contact will not change, and it is impossible to ensure that a good contact effect can be achieved between the two; thus, it may affect the working efficiency of the equipment and increase invalid working time and cost. In the technical scheme disclosed by the utility model, the rotation action of the probe rod body is used to ensure the parallelism between the probe end face and the battery contact surface, and increase the contact area between the two. At the same time, the rotation action provided can effectively destroy the insulation of the contact surface and further reduce the contact impedance. In addition, when the probe is pressed down and rotated, the contact process between the probe and the battery cap will undergo a dynamic rotation process, making the contact surface of the probe and the battery more parallel; thereby, the current carrying capacity of the probe is increased; and the contact surface of the battery is protected so that it does not leave an indentation.
