Description

Technical Field

[0001] This application relates to the field of detection technology, and in particular to a battery mounting structure and detection device. Background Technology

[0002] Detection equipment (such as nonlinear node detectors and electronic listening devices) typically identifies whether a target is an electronic device, an explosive device with a timing function, etc., by receiving the electromagnetic wave signals radiated by the target.

[0003] The detection equipment needs to have sufficient power to meet detection demands. If the detection equipment is rechargeable, with the battery built into the casing, charging takes time, which may affect normal use and prevent it from meeting sudden detection needs, thus reducing the ease of use of the equipment. Utility Model Content

[0004] Therefore, it is necessary to provide a battery mounting structure and a detection device to address the issue of ease of use of the detection equipment.

[0005] A first aspect of this application provides a battery mounting structure, the battery mounting structure comprising:

[0006] A housing and a battery plug, the housing being for accommodating a battery and having an opening, the battery plug being disposed at the opening;

[0007] A connecting component is disposed within the housing and is electrically connected to the positive terminal of the battery;

[0008] The battery includes a transmission component and a conductive component. The transmission component is disposed on the battery plug, and the conductive component is disposed on the housing. The transmission component includes a first conductive part and a second conductive part that are conductive. The first conductive part abuts against the negative terminal of the battery, and the second conductive part abuts against the conductive component. The conductive component is electrically connected to the connection component.

[0009] In one embodiment, the conductive component includes a conductive sheet and an elastic element connected together, the elastic element being an elastic member made of a conductive material;

[0010] The conductive sheet is disposed on the housing and electrically connected to the connecting assembly. The elastic element is disposed on one side of the conductive sheet along a first direction, and the elastic element is in contact with the second conductive part along the first direction. The first direction is the direction extending along the axial direction of the battery and toward the side closer to the battery plug.

[0011] In one embodiment, the elastic member includes a first bending portion and an abutting portion connected together. One end of the first bending portion away from the abutting portion is connected to the inner peripheral surface of the conductive sheet, and the surface of the abutting portion along one side of the first direction is attached to the second conductive portion.

[0012] In one embodiment, the distance along the first direction between the plane containing the surface of the conductive sheet on one side of the first direction and the abutting portion is greater than the distance along the first direction between the plane containing the surface of the conductive sheet on one side of the first direction and the first bent portion.

[0013] In one embodiment, the elastic member further includes a second bent portion connected to the abutment portion, the second bent portion being disposed on the side of the abutment portion opposite to the first bent portion;

[0014] The distance between the plane containing the surface of the conductive sheet on one side of the first direction and the abutting portion along the first direction is greater than the distance between the plane containing the surface of the conductive sheet on one side of the first direction and the second bent portion along the first direction.

[0015] In one embodiment, a receiving groove is provided on the inner circumferential surface of the conductive sheet. The receiving groove has a first groove wall and a second groove wall arranged circumferentially around the conductive sheet. The first bent portion is connected to the first groove wall, and there is a gap between the end of the second bent portion away from the abutting portion and the second groove wall.

[0016] In one embodiment, a plurality of elastic elements are provided, and the plurality of elastic elements are arranged at circumferential intervals around the conductive sheet.

[0017] In one embodiment, the orthographic projections of the plurality of elastic elements on a first plane are all located on the same annulus, the first plane being parallel to the surface of the conductive sheet on one side along the first direction.

[0018] In one embodiment, the conductive component includes a first attachment portion connected to the conductive sheet, the first attachment portion being disposed on one side of the conductive sheet along a second direction, wherein the second direction is opposite to the first direction, the first attachment portion being connected to the housing and electrically connected to the connecting component.

[0019] In one embodiment, the second conductive part is a conductive layer made of a conductive material, and the conductive layer abuts against the elastic member.

[0020] In one embodiment, multiple elastic elements are provided, and the orthographic projection of each elastic element on the first plane is arc-shaped. Each elastic element is arranged around the circumference of the conductive sheet, and the first plane is parallel to the surface of the conductive sheet on one side along the first direction.

[0021] The number of the second conductive part is one or more; the conductive layer is arc-shaped, and each of the conductive layers is arranged circumferentially around the battery plug.

[0022] A second aspect of this application provides a detection device, including a battery and the battery mounting structure described in any of the preceding claims, wherein the battery is disposed within the housing.

[0023] The aforementioned battery mounting structure utilizes a housing to accommodate the battery, with a battery plug detachably connected to the housing. The battery plug is equipped with a transmission component. The positive terminal of the battery is electrically connected to a connecting component, and the negative terminal of the battery abuts against the first conductive part of the transmission component. Furthermore, the second conductive part of the transmission component abuts against a conductive component, which in turn is electrically connected to the connecting component. This creates a current loop formed by the connecting component, battery, transmission component, and conductive component, enabling electrical conduction. In other words, after installation, the battery plug not only seals the opening in the housing to prevent battery loss or leakage but also works with the battery and transmission component to form a current loop, thereby powering other electronic components in the detection device and ensuring its normal operation. Moreover, when the battery is depleted or has insufficient power, the battery plug can be removed and a new battery replaced. The battery mounting structure of this embodiment allows for convenient battery replacement, freeing the detection device from limitations imposed by charging cable length and charging time, thus improving the ease of use of the detection device.

[0049] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-14 The specific embodiments of this application are described in detail below. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0050] One embodiment of this application provides a battery mounting structure, such as... Figures 1 to 7 As shown, the battery mounting structure may include a housing 100, a battery plug 200, a connecting assembly 300, a transmission assembly 400, and a conductive assembly 500. The housing 100 is used to accommodate the battery 600 and has an opening 170. The battery plug 200 is disposed at the opening 170. The connecting assembly 300 is disposed within the housing 100 and is electrically connected to the positive terminal of the battery 600. The transmission assembly 400 is disposed on the battery plug 200, and the conductive assembly 500 is disposed in the housing 100. The transmission assembly 400 includes a first conductive portion 410 and a second conductive portion 420. The first conductive portion 410 abuts against the negative terminal of the battery 600, and the second conductive portion 420 abuts against the conductive assembly 500. The conductive assembly 500 is electrically connected to the connecting assembly 300.

[0051] The aforementioned battery mounting structure utilizes a housing 100 to house a battery 600. A battery plug 200 is detachably connected to the housing 100, and a transmission component 400 is provided on the battery plug 200. The positive terminal of the battery 600 is electrically connected to a connecting component 300, and the negative terminal of the battery 600 abuts against the first conductive part 410 of the transmission component 400. Furthermore, the second conductive part 420 of the transmission component 400 abuts against a conductive component 500, and the conductive component 500 is electrically connected to the connecting component 300. Thus, the connecting component 300, the battery 600, the transmission component 400, and the conductive component 500 form a current loop, achieving electrical conduction. In other words, after installation, the battery plug 200 not only seals the opening 170 of the housing 100 to prevent the battery 600 from being lost or leaked, but also works with the battery 600 and the transmission component 400 to form a current loop, thereby supplying power to other electronic components in the detection equipment and ensuring the normal operation of the detection equipment. Furthermore, when the battery 600 is depleted or has insufficient power, the battery plug 200 can be removed and a new battery 600 can be replaced. The battery installation structure of this embodiment allows for convenient replacement of the battery 600, thereby freeing the detection device from the limitations of charging cable length and charging time, and improving the ease of use of the detection device.

[0052] It should be noted that the conduction of the first conductive part 410 and the second conductive part 420 of the transmission component 400 means that an electrical connection is formed between the first conductive part 410 and the second conductive part 420, enabling the transmission of power or electrical signals between the first conductive part 410 and the second conductive part 420. However, this embodiment does not impose specific restrictions on their structural arrangement. The negative terminal of the battery 600 abuts against the first conductive part 410 of the transmission component 400, meaning that structurally, the negative terminal of the battery 600 abuts against the first conductive part 410. Since both are conductive, an electrical connection is also established between them, ensuring the transmission of power or electrical signals between them. The second conductive part 420 abuts against the conductive component 500, meaning that structurally, the second conductive part 420 abuts against the conductive component 500. Since both are conductive, an electrical connection is also established between them, ensuring the transmission of power or electrical signals between them. An electrical connection means that power or electrical signals can be transmitted between them, but there are no restrictions on their structural arrangement.

[0053] In some embodiments, the battery plug 200 can be interference-fitted with the opening 170 on the housing 100. The battery plug 200 can be directly inserted into the opening 170 of the housing 100 to seal the opening 170. When disassembling, it can be pulled out by force, making installation and removal relatively quick and convenient.

[0054] In one example (not shown in the figure), the battery plug 200 may be provided with an elastic member, which achieves an interference fit with the opening 170 through the elastic restoring force of the elastic member.

[0055] In another example (not shown in the figure), an elastic member can be provided on the inner wall of the opening 170, and the interference connection with the battery plug 200 is achieved by the elastic restoring force of the elastic member.

[0056] The elastic component can be a silicone part, a rubber part, etc. Those skilled in the art can select and adjust the type, shape and size of the elastic component according to actual needs, so as to achieve an interference fit between the battery plug 200 and the opening 170.

[0057] In the example above, the battery plug 200 can be detachably connected to the opening 170 via an elastic member. However, the connection stability of the elastic member is poor. Under the influence of external forces, it is very easy for it to shake or fall off accidentally, which will affect the stability of the electrical connection.

[0058] Therefore, in some embodiments, such as Figures 1 to 6 As shown, the battery plug 200 and the housing 100 can be securely connected by threads. For example, an external thread 210 can be provided on the battery plug 200, and an internal thread 1701 can be provided on the inner wall of the opening 170. When the battery plug 200 is screwed into the opening 170, the external thread 210 and the internal thread 1701 cooperate with each other, thereby achieving a secure connection between the housing 100 and the battery plug 200. The threaded connection between the housing 100 and the battery plug 200 provides better stability, both in terms of structural and electrical connections.

[0059] More specifically, such as Figures 1 to 6 As shown, the battery plug 200 has a columnar structure, and an external thread 210 is provided on the outer peripheral surface of the columnar battery plug 200. A transmission component 400 is provided on the end face of the battery plug 200.

[0060] In some embodiments, such as Figures 7 to 12 As shown, the conductive component 500 may include a conductive sheet 510 and an elastic member 520 connected to each other. The elastic member 520 is an elastic member made of conductive material. The conductive sheet 510 is disposed on the housing 100 and electrically connected to the connecting component 300. The elastic member 520 is disposed on one side of the conductive sheet 510 along a first direction, and the side of the elastic member 520 along the first direction is in contact with the second conductive portion 420 of the transmission component 400. The first direction is the direction extending along the axial direction of the battery 600 and toward the side closer to the battery plug 200.

[0061] It should be noted that the side along the first direction refers to the side facing the battery plug 200. The position of the elastic member 520 can be set accordingly to the position of the second conductive part 420. For example, after the battery plug 200 is screwed into the opening 170, the elastic member 520 and the second conductive part 420 are in complete or partial contact.

[0062] An elastic element 520 is provided on one side of the conductive sheet 510 along the first direction. As the battery plug 200 is gradually screwed into the opening 170, the second conductive part 420 abuts against the elastic element 520 of the conductive assembly 500. As the screwing stroke increases, the pressure of the second conductive part 420 forces the elastic element 520 to undergo elastic deformation. After the elastic element 520 deforms, due to its elasticity, under the action of the elastic restoring force, the elastic element 520 always tends to move towards the battery plug 200, thereby ensuring a more stable contact between the elastic element 520 and the second conductive part 420 and ensuring the stability of the electrical connection.

[0063] In some embodiments, the conductive sheet 510 and the elastic element 520 can be conductive components made of metallic materials, such as copper or aluminum. Those skilled in the art can select and adjust the type of conductive component according to actual needs such as cost and manufacturing difficulty.

[0064] In some embodiments of this application, the conductive sheet 510 and the elastic element 520 can be made of copper, which has good electrical and thermal conductivity as well as ductility. Furthermore, copper has strong corrosion resistance and good antibacterial properties. In addition, copper is relatively inexpensive and easy to mass-produce.

[0065] For example, the conductive sheet 510 and the elastic element 520 are beryllium copper parts. Beryllium copper parts have better elasticity and excellent fatigue resistance, and can withstand more deformations without fatigue damage.

[0066] In some embodiments, the conductive sheet 510 and the elastic element 520 may be beryllium copper and may be plated with a hard gold layer to enhance the conductivity of the conductive sheet 510 and the elastic element 520.

[0067] In some embodiments of this application, please refer to the reference. Figures 2 to 6 The second conductive part 420 can be a conductive layer made of conductive material, and the conductive layer abuts against the elastic member 520.

[0068] In one example, the first conductive part 410 can be a spring, with one end connected to the end face of the battery plug 200 and the other end abutting against the negative terminal of the battery 600. The second conductive part 420 is disposed on the end face of the battery plug 200 and is attached to the elastic member 520 of the conductive component 500, thereby realizing the electrical connection of the battery 600.

[0069] In some embodiments of this application, the second conductive portion 420 can be a conductive component made of a metallic material, facilitating electrical conduction. For example, in some embodiments, the second conductive portion 420 can be a gold-plated layer.

[0070] In the aforementioned scheme where the battery plug 200 is detachably connected to the opening 170 via threads, during the screwing-in process, the battery plug 200 will cause the second conductive part 420 to rotate synchronously. Generally, the second conductive part 420 on the battery plug 200 is typically made of a softer material, such as a gold-plated layer with good conductivity, while the elastic element 520 is made of metal, such as copper, which is harder. Therefore, the second conductive part 420 may rub against the sharp edge of the elastic element 520 on the conductive assembly 500 during rotation, resulting in damage. In some embodiments of this application, such as... Figures 9 to 12 As shown, the elastic member 520 includes a first bent portion 521 and an abutting portion 522 connected together. One end of the first bent portion 521 away from the abutting portion 522 is connected to the inner peripheral surface of the conductive sheet 510. The surface of the abutting portion 522 along one side of the first direction is attached to the second conductive portion 420. The abutting portion 522 of the elastic member 520 is connected to the inner peripheral surface of the conductive sheet 510 through the first bent portion 521. When the battery plug 200 is screwed into the opening 170, the abutting portion 522 undergoes elastic deformation based on the pressure of the second conductive portion 420. The abutting portion 522 of the elastic member 520 abuts against the second conductive portion 420 along one side of the first direction, thereby ensuring that the conductive assembly 500 and the second conductive portion 420 are always in surface-to-surface contact. Since this embodiment uses a surface-to-surface contact method, that is, there are no sharp points where the contact part 522 contacts the second conductive part 420, the situation where sharp points at the boundary scratch the second conductive part 420 and cause damage can be avoided.

[0071] Furthermore, in order to improve the stability of the electrical connection between the battery plug 200 and the elastic element 520, such as Figures 7 to 12 As shown, the distance D1 along the first direction between the surface of the conductive sheet 510 on one side of the first direction and the abutment portion 522 (e.g., ...) Figure 11 As shown), the distance D2 between the surface of the conductive sheet 510 along the first direction and the first bent portion 521 along the first direction is greater than the distance D2 along the first direction (as shown). Figure 11 (As shown). That is, the abutting portion 522 protrudes outward in the first direction compared to the first bent portion 521. The abutting portion 522 is closer to the battery plug 200 than the first bent portion 521. After the elastic member 520 undergoes elastic deformation, under the action of elastic restoring force, the abutting portion 522 always tends to move towards the battery plug 200, which can ensure that the abutting portion 522 is always abutting against the second conductive portion 420 of the battery plug 200, thereby making the electrical connection stability between the battery plug 200 and the elastic member 520 better.

[0072] In some embodiments of this application, such as Figures 7 to 12As shown, the elastic member 520 may further include a second bent portion 523 connected to the abutment portion 522, the second bent portion 523 being disposed on the side of the abutment portion 522 opposite to the first bent portion 521; the distance D1 between the surface of the conductive sheet 510 on one side along the first direction and the abutment portion 522 along the first direction (e.g., ...) Figure 11 As shown), the distance D3 between the surface of the conductive sheet 510 along the first direction and the second bent portion 523 along the first direction is greater than the distance D3 along the first direction. Figure 11 (As shown). That is, the elastic member 520 has a shape that is high in the middle and gradually decreases on both sides. After elastic deformation, the second bending part 523 abuts against one side end face of the structure in the housing 100 for mounting the battery 600 (for example, the battery rack 160 described below). Since the first bending part 521 is connected to the conductive sheet 510, the second bending part 523 can cooperate with the first bending part 521 to support the abutting part 522 on both sides. That is, after the elastic member 520 is deformed, it is such that both sides abut against one side end face of the structure in the housing 100 for mounting the battery 600 (for example, the battery rack 160 described below), and the middle abutting part 522 is slightly higher than the stable structure of the first bending part 521 and the second bending part 523 on both sides. Under the action of elastic restoring force, it can ensure that the abutting part 522 is always abutting against the second conductive part 420, ensuring the stability of the electrical connection.

[0073] In one embodiment of this application, as Figure 10 As shown, a receiving groove 511 is provided on the inner circumferential surface of the conductive sheet 510. The receiving groove 511 has a first groove wall 5111 and a second groove wall 5112 arranged circumferentially around the conductive sheet 510. A first bent portion 521 is connected to the first groove wall 5111, and a gap exists between the end of the second bent portion 523 facing away from the abutting portion 522 and the second groove wall 5112. The receiving groove 511 is provided on the inner circumferential surface of the conductive sheet 510, and the elastic member 520 extends at least partially into the receiving groove 511. The first bent portion 521 is connected to the first groove wall 5111, thereby achieving the connection between the conductive sheet 510 and the elastic member 520. When the elastic member 520 abuts against the second conductive portion 420, the elastic member 520 deforms, and a gap exists between the end of the second bent portion 523 facing away from the abutting portion 522 and the second groove wall 5112, thus providing space for the abutting portion 522 to elastically deform.

[0074] In other embodiments, the receiving groove 511 may be omitted, and one end of the first bent portion 521 may be directly connected to the inner circumferential surface of the conductive sheet 510. The hollow area inside the conductive sheet 510 provides deformation space for the elastic member 520.

[0075] In some embodiments, such as Figures 7 to 12As shown, multiple elastic elements 520 can be provided, arranged circumferentially around the conductive sheet 510. By providing multiple elastic elements 520, when the second conductive part 420 abuts against multiple elastic elements 520, all elastic elements 520 can abut against the second conductive part 420 and undergo elastic deformation. By providing multiple elastic elements 520, if one elastic element 520 is damaged or has dirt on its surface preventing electrical connection, electrical connection can still be achieved through other elastic elements 520, ensuring the normal operation of the detection device. Furthermore, the multiple elastic elements 520 can be evenly and spaced on the conductive sheet. Since the elastic elements 520 have thickness, evenly spaced arrangement of multiple elastic elements 520 also ensures that the battery plug 200 will not tilt after being screwed in, and will not damage the threads inside the battery plug 200 and the opening 170.

[0076] In some embodiments of this application, such as Figures 7 to 12 As shown, the orthographic projections of multiple elastic elements 520 on the first plane are all located on the same ring, and the first plane is parallel to the surface of the conductive sheet 510 along the first direction.

[0077] In the battery mounting structure provided in this application embodiment, the orthographic projections of multiple elastic elements 520 can be defined as being located on the same circular ring, that is, multiple elastic elements 520 extend circumferentially around the same circular ring. This ensures that the contact points between the multiple elastic elements 520 and the end face of the second conductive part 420 facing the conductive sheet 510 are evenly distributed, and that multiple contact points are located on the same circular ring, avoiding localized poor contact or excessive resistance. Furthermore, with the contact points evenly distributed on the circular ring, the contact friction generated between the multiple elastic elements 520 and the second conductive part 420 can also be evenly distributed at multiple positions on the same circular ring, preventing excessive localized wear and extending the service life of the elastic elements 520 and the second conductive part 420 in contact with them. In addition, the multiple elastic elements 520 are arranged circumferentially around the conductive sheet 510 at intervals, and their orthographic projections are located on the same circular ring. The layout of the elastic elements 520 on the conductive sheet 510 is relatively regular, which is conducive to the standardization and modular design of the conductive component 500, and reduces the requirements for molds, making it easier to use mold forming, stamping and other processes for mass production, thereby improving production efficiency.

[0078] Specifically, the deformation directions of multiple elastic elements 520 can be consistent; for example, each elastic element 520 can deform in a clockwise or counterclockwise direction. For example, in Figure 8 In this process, multiple elastic elements 520 can deform around the circumference of the conductive sheet 510, i.e., in a clockwise direction. By limiting the deformation direction of multiple elastic elements 520, the situation where two adjacent elastic elements 520 touch each other due to deformation is avoided.

[0079] In this embodiment, as Figures 7 to 12As shown, multiple elastic elements 520 can be provided. The orthographic projection of each elastic element 520 on the first plane is arc-shaped. Each elastic element 520 is arranged circumferentially around the conductive sheet 510, and the first plane is parallel to the surface of the conductive sheet 510 along the first direction. Meanwhile, referring to... Figure 6 The number of second conductive parts 420 is more than one, that is, the transmission assembly 400 includes more than one conductive layer. Each conductive layer is arc-shaped and arranged circumferentially around the battery plug 200.

[0080] In this embodiment, multiple elastic elements 520 are arranged circumferentially around the conductive sheet 510, and multiple second conductive portions 420 are provided on the battery plug 200, also arranged circumferentially around the battery plug 200. After the battery plug 200 is screwed in, all the elastic elements 520 can abut against the multiple second conductive portions 420. Furthermore, the orthographic projection of the elastic element 520 and the shape of the conductive layer are both arc-shaped, and their shapes are compatible, allowing for greater contact area. In addition, the orthographic projection of the elastic element 520 is arc-shaped, and its deformation direction is the same as the rotation direction of the battery plug 200. That is, during the process from the beginning of deformation to the limit position of deformation, the abutting portion 522 of the elastic element 520 and the second conductive portions 420 on the battery plug 200 move almost synchronously, and the two are in surface-to-surface contact, reducing wear between them.

[0081] In some embodiments, the conductive sheet 510 can be an annular member, and the outer ring contour of the conductive sheet 510 can be circular, elliptical, etc., while the inner ring contour of the conductive sheet 510 is circular. Multiple elastic members 520 can be provided and arranged circumferentially around the inner ring of the conductive sheet 510, with one end of each elastic member 520 connected to the inner circumferential surface of the conductive sheet 510.

[0082] In one example, four elastic elements 520 may be provided, arranged circumferentially around the inner ring of the conductive sheet 510. Two second conductive portions 420 are semi-circular arc-shaped plates, arranged circumferentially around the battery plug 200. When the battery plug 200 is screwed into the locked position, two of the four elastic elements 520 abut against one of the second conductive portions 420, and the other two elastic elements abut against the other second conductive portion 420.

[0083] In other examples, the number of elastic elements 520 and second conductive parts 420 is set according to actual operational needs. For example, the number of elastic elements 520 and second conductive parts 420 is equal, and when the battery plug 200 is screwed into the opening 170, multiple elastic elements 520 and multiple second conductive parts 420 abut against each other in a one-to-one correspondence. For example, four elastic elements 520 and four second conductive parts 420 are provided, and when the battery plug 200 is screwed into the locked position, four elastic elements 520 and four second conductive parts 420 abut against each other in a one-to-one correspondence.

[0084] To solve the problem of electrical connection between the first conductive part 410 and the second conductive part 420, such as Figure 6 As shown, in some embodiments, the transfer assembly 400 may further include an electrode adapter plate 430, which is disposed on the end face of the battery plug 200. A second conductive part 420 (conductive layer) is laid on the electrode adapter plate 430, and a first conductive part 410 is connected to one end of the battery plug 200 and contacts the electrode adapter plate 430. After the battery plug 200 is screwed into the opening 170, the first conductive part 410 (spring) on ​​the battery plug 200 abuts against the negative terminal of the battery 600. An electrode adapter plate 430 is provided on the end face of the battery plug 200. The second conductive part 420 (conductive layer) abuts against the conductive component 500 inside the housing 100. The conductive component 500 is electrically connected to the connecting component 300. The connecting component 300 is connected to the positive terminal of the battery 600. Thus, the battery 600, the first conductive part 410, the electrode adapter plate 430, the second conductive part 420, the conductive component 500, and the connecting component 300 form a current loop, realizing electrical conduction.

[0085] In some embodiments of this application, the connection component 300 may include a circuit board, the positive terminal of which is connected to the positive terminal of the battery 600, and the negative terminal of which is electrically connected to the conductive component 500 via a connector 310.

[0086] In one example, such as Figure 8 As shown, signal input / output interfaces 320, such as audio interfaces and data transmission interfaces, can be provided on the circuit board, and through holes 190 are provided on the housing 100 to expose the signal input / output interfaces 320.

[0087] To facilitate the installation of electronic components inside the housing 100. In some embodiments, such as Figures 2 to 5As shown, the housing 100 may include a first outer shell 140 and a second outer shell 150. When the first outer shell 140 and the second outer shell 150 are fastened together, the interior is a cavity. A portion of the cavity is a battery cavity 110. The housing 100 has an opening 170 communicating with the battery cavity 110, through which the battery 600 can be placed within the battery cavity 110. Furthermore, other electronic components (such as the detection module, the connection assembly 300, etc.) can be placed in one of the first outer shell 140 and the second outer shell 150 before the other is fastened together, which facilitates installation.

[0088] In one example, the diameter of opening 170 can be slightly larger than the diameter of battery 600. The user can remove and replace the battery by changing the orientation of the detection device or by shaking it, using gravity. For example, the difference between the diameter of opening 170 and the diameter of battery 600 is greater than 1 mm and less than 1 cm.

[0089] In another example, the diameter of opening 170 can be much larger than the diameter of battery 600; for example, the difference between the diameter of opening 170 and the diameter of battery 600 can be greater than or equal to 1 cm. Compared to the above example, users can more easily remove and replace the battery using their fingers or other tools without changing the orientation of the detection device.

[0090] In some embodiments of this application, such as Figures 2 to 5 ,as well as Figure 13 As shown, a battery rack 160 can be provided inside the battery cavity 110. The battery rack 160 is a hollow component with a receiving cavity 161 formed in the hollow part for accommodating the battery 600. The battery 600 is disposed in the receiving cavity 161 inside the battery rack 160.

[0091] In one specific embodiment (not shown in the figure), the battery holder 160 may be integrally formed with the first housing 140 or the second housing 150.

[0092] In one specific embodiment (not shown in the figure), the battery holder 160 can be divided into a first part and a second part, wherein one of the first part and the second part is integrally formed with the first housing 140 and the other is integrally formed with the second housing 150.

[0093] In one specific embodiment, such as Figure 2 , Figure 11 As shown, the battery holder 160 and the housing 100 are two independent components that can be connected to the housing 100 by means of connectors (such as screws, clips, adhesives, etc.).

[0094] To solve the installation problem of the conductive sheet 510, in one embodiment of this application, as follows: Figures 8 to 9As shown, the conductive component 500 may include a first mounting portion 530 connected to the conductive sheet 510. The first mounting portion 530 is disposed on one side of the conductive sheet 510 along a second direction. The second direction is opposite to the first direction. The first mounting portion 530 is connected to the housing 100 and electrically connected to the connecting component 300. By providing the first mounting portion 530 on one side of the conductive sheet 510 along the second direction, the first mounting portion 530 is connected to the battery holder 160 of the housing 100, thereby achieving the connection between the conductive component 500 and the housing 100. Furthermore, the first mounting portion 530 is electrically connected to the connector 310 on the circuit board of the connecting component 300, thereby enabling the battery 600 to conduct electricity. In other words, the first mounting portion 530 has both mounting and electrical conduction functions.

[0095] In a specific example, such as Figure 9 As shown, the first mounting part 530 may include a first plate 531 and a second plate 532 that are arranged at an angle and connected to each other. The end of the first plate 531 facing away from the second plate 532 is connected to the outer peripheral surface of the conductive sheet 510, and the second plate 532 extends radially toward the side closer to the inner peripheral surface of the conductive sheet 510.

[0096] In a specific example, as shown in 9, the included angle between the first plate 531 and the second plate 532 is 90°.

[0097] In a specific example, the included angle between the first plate 531 and the second plate 532 is set according to the actual operation. For example, it can be an angle of 60°, 70°, 80°, etc.

[0098] In one embodiment of this application, such as Figures 7 to 13 As shown, in this embodiment, the first mounting part 530 can be mounted on the battery rack 160 disposed inside the battery cavity 110 of the housing 100.

[0099] In some embodiments of this application, such as Figures 7 to 12 As shown, multiple first hook-on portions 530 can be provided, and the multiple first hook-on portions 530 are arranged at intervals along the circumference of the conductive sheet 510. Providing multiple first hook-on portions 530, all of which are connected to the housing 100, improves the installation stability of the conductive component 500 within the housing 100. Furthermore, if the first hook-on portions 530 adopt the arrangement of the first plate 531 and the second plate 532 described above, the multiple first hook-on portions 530 can limit the movement of the conductive component 500 in the axial and radial directions of the battery 600, reducing the shaking of the conductive component 500 within the battery 600.

[0100] In one example, two first hook-up portions 530 may be provided, and the two first hook-up portions 530 are symmetrically arranged along the axial direction of the conductive sheet 510, which reduces the amount of material used and also limits the position of the conductive sheet 510.

[0101] Furthermore, in the case where the battery plug 200 is screwed into the opening 170, there is friction between the elastic element 520 and the battery plug 200 during the deformation process. Therefore, the conductive sheet 510 may be forced to rotate under the action of friction, which may affect the stability of the electrical connection.

[0102] Therefore, in some embodiments, such as Figure 13 and Figure 14 As shown, two sealing members 164 can be provided at intervals on the outer wall 163 of the battery rack 160. The first hook part 530 is hooked between the two sealing members 164. The two sealing members 164 can limit the first hook part 530 along the circumference of the battery rack 160, which can prevent the conductive sheet 510 from rotating and ensure the stability of the electrical connection between the elastic member 520 on the conductive sheet 510 and the second conductive part 420.

[0103] In other examples, the number of first attachments 530 can be set according to actual operational needs.

[0104] To further improve the installation stability of the conductive sheet 510 and the elastic element 520, such as Figure 9 , Figure 12 As shown, the conductive component 500 includes a second hook portion 540 connected to the conductive sheet 510. The second hook portion 540 is connected to the inner ring of the conductive sheet 510 and extends along a second direction. By providing the second hook portion 540, the second hook portion 540 is used to connect with the inner sidewall 162 of the battery holder 160. That is, the first hook portion 530 is hooked on the outer sidewall 163 of the battery holder 160, and the second hook portion 540 abuts against the inner sidewall 162 of the battery holder 160. The first hook portion 530 and the second hook portion 540 cooperate with each other to limit the movement of the conductive component 500 in a third direction and the axial direction of the battery 600, wherein the third direction is perpendicular to the first direction or the second direction.

[0105] It should be noted that the third direction is perpendicular to the first or second direction, that is, the third direction is the radial direction of the battery 600. In some embodiments of this application, such as Figures 7 to 13As shown, multiple second hook-up portions 540 can be provided, and these portions are arranged at intervals along the circumference of the conductive sheet 510. Providing multiple second hook-up portions 540, all of which are connected to the inner sidewall 162 of the battery holder 160, improves the installation stability of the conductive assembly 500. In one example, two second hook-up portions 540 can be provided, symmetrically arranged along the axial direction of the conductive sheet 510. These two second hook-up portions 540 limit the radial movement of the conductive assembly 500 in the battery 600, reducing the radial sway of the conductive assembly 500 in the battery 600. In other examples, the number of second hook-up portions 540 can be set according to actual operational needs.

[0106] In some embodiments, such as Figure 13 and Figure 14 As shown, a groove 165 can be formed on the inner sidewall 162 of the battery holder 160. The second hook part 540 is hooked in the groove 165, and the groove depth of the groove 165 is greater than or equal to the thickness of the second hook part 540. This ensures that the second hook part 540 does not protrude from the inner sidewall 162 of the battery holder 160 after hooking. This makes the insertion and removal of the battery 600 smoother and improves the ease of use of the detection device.

[0107] In some embodiments of this application, such as Figures 7 to 13 As shown, a plurality of first coupling portions 530 and a plurality of second coupling portions 540 are arranged at intervals along the circumference of the conductive sheet 510. The plurality of first coupling portions 530 and the plurality of second coupling portions 540 cooperate with each other to limit the conductive component 500 in multiple directions.

[0108] In one example, such as Figures 7 to 12 As shown, two first hook portions 530 and two second hook portions 540 are arranged at intervals along the circumference of the conductive sheet 510. For example, the two first hook portions 530 are symmetrically arranged on opposite sides of the conductive sheet 510 in the radial direction, while the two second hook portions 540 are symmetrically arranged on opposite sides of the conductive sheet 510 along a direction perpendicular to the line connecting the two first hook portions 530.

[0109] One embodiment of this application also provides a detection device; please refer back to the previous section. Figures 1 to 5 The detection device may include a battery 600 and the aforementioned battery mounting structure. The battery mounting structure includes a housing 100, and the battery 600 is disposed within the housing 100. By installing the battery 600 within the housing 100, and by ensuring that the battery 600 can be replaced at any time, the detection device is no longer limited by the length of the charging cable and the charging time, thus improving the ease of use of the detection device. Furthermore, by mounting the battery 600 through the battery mounting structure, an electrical connection is established for the battery 600, thereby enabling the battery 600 to power other components of the detection device.

[0110] It should be noted that the battery mounting structure provided in this application embodiment can be applied to the above-mentioned detection equipment, as well as to other electrical equipment.

[0111] In some embodiments of this application, such as Figures 1 to 5 As shown, the detection device may further include a detection component 700, which is housed within the housing 100 and electrically connected to the battery 600. If the detection device is a nonlinear node detector, the detection component 700 may include, for example, a transmitting unit, a receiving unit, and a signal processing unit. The transmitting unit emits a fundamental wave towards the target area or target object, and the receiving antenna captures the second and third harmonic signals generated by the target object. The receiving unit amplifies and mixes the received harmonic signals before sending them to the signal processing unit. The signal processing unit uses appropriate algorithms to analyze the received harmonic signals, thereby determining whether a nonlinear node exists in the target object or identifying the type of target object. The detection component 700 is electrically connected to the battery 600, which provides power to the detection component 700, ensuring its normal operation.

[0112] It should be noted that the detection component 700 can be a detection component capable of detecting nonlinear nodes, a detection component capable of detecting metal, or other types of detection components. Those skilled in the art can select and adjust the type of the detection component 700 according to actual needs.

[0113] In one example, such as Figures 1 to 5 As shown, another part of the cavity formed by the first outer shell 140 and the second outer shell 150 is the detection cavity 120. The detection cavity 120 is used to accommodate the detection component 700 of the detection device, and the detection cavity 120 is connected to the battery cavity 110 and the opening 170 mentioned above.

[0114] In this embodiment, as Figure 2 and Figure 3 As shown, the battery cavity 110 and the detection cavity 120 are arranged at intervals along the length of the housing 100.

[0115] In one example, such as Figures 1 to 5 As shown, the housing 100 includes a probe portion 180 arranged along the length of the housing 100 and a handle portion 130 for easy gripping by the user. The detection cavity 120 is located inside the probe portion 180, the battery cavity 110 is located inside the handle portion 130, and an opening 170 is provided at the bottom end of the handle portion 130.

[0116] In some embodiments, the detection component 700 may be a nonlinear node detection component, and the connection component 300 may include a circuit board, on which a signal input / output interface 320 may be provided.

[0117] Since the circuit board contains many electronic components, and some of these components may contain nonlinear nodes, these components may generate second and third harmonic signals under the influence of the fundamental wave signal. These harmonic signals can be received by the detection component 700, leading to false alarms. Therefore, in some embodiments, the circuit board can be located inside the handle portion 130, between the battery holder 160 and the inner wall of the housing 100. That is, the circuit board is located between the battery cavity 110 and the receiving cavity 161, and not inside the detection cavity 120. This means the circuit board is far from the detection cavity 120, and the main lobe direction of the fundamental wave emitted by the detection component 700 is not towards the handle portion 130. This avoids the circuit board affecting the detection component 700 and reduces the false alarm rate. In addition, if the circuit board is placed inside the detection cavity 120, the volume of the detection cavity 120 will also increase. Since the handle part 130 is relatively long, slightly increasing the diameter of the handle part 130 will allow enough space to be reserved between the receiving cavity 161 and the battery cavity 110 to accommodate the circuit board. This facilitates the accommodation of the circuit board without excessively increasing the volume of the handle part 130, thus rationally planning the space inside the housing 100.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
