Description

Technical Field

[0001] This application relates to the field of lighting technology, specifically to a folding lamp. Background Technology

[0002] Secondary batteries are rechargeable, meaning they can store electrical energy after discharging through a charging process for reuse; examples include lithium batteries. These batteries typically consist of a casing and, within the casing, an electrolyte, a positive electrode, a negative electrode, and a separator. The separator insulates and isolates the positive and negative electrodes while allowing lithium-ion transport.

[0003] As a key material in batteries, the quality of the separator directly affects the battery's safety and electrochemical performance. Therefore, separator quality inspection is particularly important. During incoming separator inspection and battery disassembly analysis, the quality of the separator is typically assessed by examining its appearance. To improve the accuracy of separator appearance inspection, a light source is used to illuminate the separator, allowing observers to more visually assess its quality.

[0004] In related technologies, light is primarily emitted from a fixed light-transmitting panel and directed onto the diaphragm to facilitate inspection of its quality. However, this type of equipment is bulky and difficult to move, making it unsuitable for the rapid sampling or mobile inspection needs of production lines. Utility Model Content

[0006] An embodiment of this application provides a folding lamp with a first light-emitting side. The folding lamp includes multiple light source modules and multiple hinge parts. The multiple light source modules are arranged in parallel. A hinge part is provided between two adjacent light source modules, and the hinge part hinges the two adjacent light source modules. When the folding lamp is unfolded, the multiple light source modules are arranged in sequence along a first direction. The surface of each light source module facing the first light-emitting side and the surface of each hinge part facing the first light-emitting side are both light-transmitting surfaces.

[0007] In one embodiment, the folding lamp further has a second light-emitting side, and the surface of each light source module facing the second light-emitting side and the surface of each hinge facing the second light-emitting side are both light-transmitting surfaces.

[0008] In one embodiment, the material of the surface of the molded light source module facing the second light-emitting side and the surface of the hinge facing the second light-emitting side is one of the following materials: acrylic, glass, PC, PET.

[0009] In one embodiment, the material of the surface of the molded light source module facing the first light-emitting side and the surface of the hinge facing the first light-emitting side is one of the following materials: acrylic, glass, PC, PET.

[0010] In one embodiment, the hinges between multiple light source modules are sorted along a first direction, with the hinges ordered by odd number being the first hinges and the hinges ordered by even number being the second hinges; wherein, the hinge axis of the first hinge is located on the side of the light source module facing the first light-emitting side, and the hinge axis of the second hinge is located on the side of the light source module away from the first light-emitting side.

[0011] In one embodiment, the light source modules at the beginning and end of the first direction are both end modules. A support portion is provided on the side of the end module away from the adjacent light source module. One side of the support portion protrudes outward along the protrusion direction of the first hinge portion to form a first protruding end. When the folding lamp is unfolded, the distance between the first protruding end and the light source module is equal to the distance between the side wall of the first hinge portion facing the first light-emitting side and the light source module.

[0012] In one embodiment, the other side of the support portion protrudes outward along the protruding direction of the second hinge portion to form a second protruding end; wherein, when the folding lamp is unfolded, the distance between the second protruding end and the light source module is equal to the distance between the side wall of the second hinge portion away from the first light-emitting side and the light source module.

[0013] In one embodiment, the hinge portion includes a pin and two lugs, with the two ends of the pin passing through the two lugs respectively, and the two lugs being connected to two adjacent light source modules respectively.

[0014] In one embodiment, the end of the pin protrudes through the ear, and there is an annular groove and a retaining spring on the outer peripheral surface of the pin protruding from the ear, with the inner peripheral side of the retaining spring being engaged in the annular groove.

[0015] In one embodiment, the pin has a hollow structure and two first wire holes, which are located at both ends of the pin, and one end of each first wire hole is connected to the hollow structure; a wire is provided between two adjacent light source modules, and the two ends of the wire are connected to the electric light source of the two adjacent light source modules, and the middle part of the wire passes through the ear, the first wire hole and the hollow structure.

[0016] In one embodiment, the other end of each first wire hole extends circumferentially along the pin shaft, and the central angle corresponding to the first wire hole in the circumferential direction of the pin shaft is α, which satisfies: 180°<α≤270°, and the two first wire holes partially overlap along the axial direction of the pin shaft.

[0017] In one embodiment, the number of light source modules is 5 to 12.

[0018] The beneficial effects of the embodiments of this application are as follows:

[0019] In the embodiments of this application, by hinged multiple light source modules to form a folding lamp, the lamp can be unfolded to provide a larger illumination area when the diaphragm quality needs to be inspected, and folded when it needs to be moved, thereby reducing its length and making it easy to carry. This improves the convenience of diaphragm appearance inspection. Furthermore, by making the surfaces of the light source modules facing the first light-emitting side and the hinge portion facing the first light-emitting side both light-transmitting surfaces, the transmittance of the light emitted by the electric light source can be increased, thereby reducing shadows and differences in brightness, allowing more light to illuminate and be transmitted through the diaphragm, increasing the brightness of the observation, and thus improving the accuracy of diaphragm inspection.

[0043] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the unfolded structure of the folding lamp 100 provided in an embodiment of this application. Figure 2 yes Figure 1 Enlarged structural diagram at point A in the middle. Figure 3 This is a schematic diagram of the internal structure of the light source module 10 provided in an embodiment of this application. An embodiment of this application provides a folding lamp 100, which has a first light-emitting side 101. The folding lamp 100 includes multiple light source modules 10 and multiple hinge portions 14. The multiple light source modules 10 are arranged side-by-side in sequence; a hinge portion 14 is provided between each adjacent two light source modules 10. The hinge portion 14 hinges adjacent two light source modules 10 together. When the folding lamp 100 is unfolded, the multiple light source modules 10 are arranged sequentially along a first direction, and the surface of each light source module 10 facing the first light-emitting side 101 and the surface of each hinge portion 14 facing the first light-emitting side 101 are both light-transmitting surfaces.

[0044] It is understood that the light source module 10 includes a housing 111 and an electric light source 13 disposed within the housing 111. The housing 111 can be an integral structure or a separate structure. For example, the housing 111 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are fastened together to define a mounting cavity 18. The electric light source 13 is disposed in the mounting cavity 18. When the folding lamp 100 is unfolded, the first housing 11 is positioned facing the first light-emitting side 101. Correspondingly, the material of the first housing 11 is a light-transmitting material. Exemplarily, the light-transmitting material includes, but is not limited to, acrylic and glass.

[0045] It can be understood that the light emitted by the electric light source 13 of the light source module 10 passes through the surface of the light source module 10 toward the first light-emitting side 101 and the surface of the hinge portion 14 toward the first light-emitting side 101 before illuminating the external environment of the folding lamp 100. Specifically, the light emitted by the electric light source 13 of the light source module 10 passes through the surface of the light source module 10 toward the first light-emitting side 101 and the surface of the hinge portion 14 toward the first light-emitting side 101 before illuminating the diaphragm.

[0046] For example, the electric light source 13 includes, but is not limited to, incandescent lamps, fluorescent lamps, and LED lamps.

[0047] It is understood that the folding lamp 100 also has a power cord 19, which connects the power source to each light source 13 to deliver electrical energy to each light source 13 so that the light source 13 emits light.

[0048] For example, the thickness of the light source module 10 (i.e., the distance between the surface of the light source module 10 facing the first light-emitting side 101 and the surface facing away from the first light-emitting side 101) is 10 mm.

[0049] It can be understood that when the folding lamp 100 is unfolded, it means that the various light source modules 10 are arranged sequentially along the first direction.

[0050] It can be understood that when the folding lamp 100 is unfolded, the light source modules 10 rotate around the hinge axis, causing the individual light source modules 10 to come closer together and be stacked, thereby reducing the size of the light source modules 10 in the first direction for easier carrying, such as... Figure 4 As shown, Figure 4 This is a schematic diagram of the folding lamp 100 when unfolded and folded according to an embodiment of this application. The folding of the folding lamp 100 can be a sequential reciprocating fold, that is, the rotation directions of two adjacent light source modules 10 are opposite during folding. For example, the second light source module 10 rotates counterclockwise relative to the first light source module 10, and the third light source module 10 rotates clockwise relative to the second light source module 10, and so on. Figure 4 As shown.

[0051] It is understandable that when diaphragm quality testing is required, the light source module 10 is rotated around the hinged axis to unfold the folding lamp 100, making the folding lamp 100 a multi-segment structure extending along the first direction, such as... Figure 1 As shown. The first light-emitting side 101 is oriented towards the diaphragm, so that the light emitted by the electric light source 13 illuminates the diaphragm, allowing the diaphragm to transmit light, so that the inspector can judge the quality of the diaphragm based on the light transmittance. When it is necessary to move or carry the folding lamp 100, the light source module 10 is rotated around the hinge axis, so that the various light source modules 10 are brought closer together and stacked, as shown. Figure 4 As shown.

[0052] For example, along the first direction, each light source module 10 has a length of 150mm, and there are 8 light source modules 10. The first and last light source modules 10 also have a 5mm long support portion 15. Correspondingly, the unfolded length of the folding lamp 100 is 150mm. 8+5mm 2 = 1210mm. Each light source module 10 can illuminate an effective width of 62mm, and the effective detection area of ​​the unfolded folding lamp 100 is 62mm². 1210mm = 75020mm 2 When folded, the length of the folding lamp 100 in the first direction becomes 150mm + 5mm = 155mm (when the support parts 15 of the first and last light source modules 10 are located on the same side of the folded lamp 100), or 150mm + 5mm + 5mm = 160mm (when the support parts 15 of the first and last light source modules 10 are located on both sides of the folded lamp 100). The folded lamp 100 is approximately 1 / 8 of its length in the unfolded state. This allows the folding lamp 100 to be easily stored in a tool bag for convenient carrying.

[0053] In this embodiment, by hinged multiple light source modules 10 to form a folding lamp 100, the folding lamp 100 can be unfolded to provide a larger illumination area when the appearance of the diaphragm needs to be inspected, and can also be folded to reduce its length for easy carrying when it needs to be moved. This improves the convenience of diaphragm appearance inspection.

[0054] Furthermore, by making both the surface of the light source module 10 facing the first light-emitting side 101 and the surface of the hinge portion 14 facing the first light-emitting side 101 light-transmitting surfaces, the transmittance of the light emitted by the light source module 10 can be improved, thereby reducing shadows and differences in brightness, and improving the observed brightness of the diaphragm. This improves the accuracy of diaphragm detection.

[0055] In one embodiment, the folding lamp 100 further has a second light-emitting side 102. The surface of each light source module 10 facing the second light-emitting side 102 and the surface of each hinge portion 14 facing away from the second light-emitting side 102 are both light-transmitting surfaces. This allows light to pass through both sides of the folding lamp 100 when unfolded, enabling users to either directly illuminate the diaphragm from one side while using the light emitted from the other side to supplement the brightness of the observed diaphragm, or to choose either side of the folding lamp 100 as the light source side, thus improving the ease of use of the folding lamp 100.

[0056] In one embodiment, the material of the surface of the molded light source module 10 facing the second light-emitting side 102 and the surface of the hinge portion 14 facing the second light-emitting side 102 is one of the following materials: acrylic, glass, PC (polycarbonate), PET (polyethylene terephthalate).

[0057] In one embodiment, the material of the surface of the molded light source module 10 facing the first light-emitting side 101 and the surface of the hinge portion 14 facing the first light-emitting side 101 is one of the following materials: acrylic, glass, PC (polycarbonate), PET (polyethylene terephthalate).

[0058] Acrylic boasts excellent optical properties, good processability, and resistance to aging. With a light transmittance of approximately 92%, approaching the transparency of glass, acrylic allows light emitted from a light source to pass through efficiently, resulting in a bright and clear visual effect.

[0059] Glass has a high light transmittance and good chemical stability. Colorless transparent glass can have a light transmittance of over 90%, providing clear and natural light transmission with almost no change to the color and quality of the light source, making the lighting effect more realistic.

[0060] PC has good light transmittance and strong impact resistance. The light transmittance of PC is generally between 85% and 90%, which can effectively transmit the light emitted by the light source and provide a bright lighting effect.

[0061] PET has good light transmittance and is relatively inexpensive. PET has a high light transmittance, generally around 88%-92%, allowing light to pass through effectively and providing a clear light transmission effect for light sources, thus meeting lighting needs.

[0062] Please see Figure 5 and Figure 6 , Figure 5 This is a side view of the unfolded folding lamp 100 provided in an embodiment of this application. Figure 6 yes Figure 5 Enlarged view at point B. In one embodiment, the hinge portions 14 between multiple light source modules 10 are arranged along a first direction, with the odd-numbered hinge portions 14 being the first hinge portion 141 and the even-numbered hinge portions 14 being the second hinge portion 142. The hinge axis of the first hinge portion 141 is located on the side of the light source module 10 facing the first light-emitting side 101, and the hinge axis of the second hinge portion 142 is located on the side of the light source module 10 away from the first light-emitting side 101, that is, the hinge axis of the second hinge portion 142 is located on the side of the light source module 10 facing the second light-emitting side 102.

[0063] For example, the first hinge portion 141 protrudes toward the light source module 10 toward the first light-emitting side 101, the second hinge portion 142 protrudes toward the light source module 10 away from the first light-emitting side 101, and the second hinge portion 142 protrudes toward the light source module 10 toward the second light-emitting side 102.

[0064] It is understandable that when folding the folding lamp 100, each light source module 10 is folded back and forth sequentially, such as... Figure 4 As shown.

[0065] In this embodiment, through the above-described scheme, when the various light source modules 10 of the folding lamp 100 are folded together to fold the lamp 100, since the axes of the first hinge portion 141 and the second hinge portion 142 are located outside the gap between two adjacent light source modules 10, the hinge portion 14 between the light source modules 10 can avoid obstructing the rotation of the light source modules 10, allowing two adjacent light source modules 10 to contact each other face to face. This allows the light source modules 10 to be stacked in parallel sequentially, reducing the size of the light source modules 10 in the stacking direction, thereby reducing the space occupied by the light source modules 10 after folding.

[0066] Please see Figure 5 and Figure 6 In one embodiment, the light source modules 10 at both ends in the first direction are end modules 10a. A support portion 15 is provided on the side of the end module 10a away from the adjacent light source module 10. One side of the support portion 15 protrudes outward along the protruding direction of the first hinge portion 141 to form a first protruding end 151. When the folding lamp 100 is unfolded, the distance D1 between the first protruding end 151 and the light source module 10 is equal to the distance D2 between the sidewall of the first hinge portion 141 facing the first light-emitting side 101 and the light source module 10. Thus, when the folding lamp 100 is unfolded and placed on a table, the light source module 10 can be flatly supported on the bearing surface by the first protruding end 151 and the protruding ends of the multiple first hinge portions 141, thereby improving the consistency of the light emission angle of each light source module 10 and improving the uniformity of the observed diaphragm brightness, which is beneficial to improving the clarity of the diaphragm.

[0067] For example, the distance D1 between the first protruding end 151 and the light source module 10 is 5mm.

[0068] Please see Figure 5 and Figure 6 In one embodiment, the other side of the support portion 15 protrudes outward along the protruding direction of the second hinge portion 142 to form a second protruding end 152. When the folding lamp 100 is unfolded, the distance D3 between the second protruding end 152 and the light source module 10 is equal to the distance D4 between the sidewall of the second hinge portion 142 away from the first light-emitting side 101 and the main light source module 10. Thus, the light source module 10 can be flatly supported on the bearing surface by the second protruding end 152 and the protruding ends of the multiple second hinge portions 142, allowing the light source module 10 to be flatly supported on both sides of the folding lamp 100. This allows for selection of either side of the folding lamp 100 for support according to the usage scenario, improving the ease of use of the folding lamp 100.

[0069] For example, the distance D3 between the second protruding end 152 and the light source module 10 is 5mm.

[0070] Specifically, the support portion 15 is a cylinder, and one side of its outer peripheral surface is connected to at least one of the adjacent first outer shell 11 and second outer shell 12. The end of the support portion 15 near the first outer shell 11 is a first protruding end 151, and the end of the support portion 15 near the second outer shell 12 is a second protruding end 152.

[0071] Please see Figure 1 , Figure 7 as well as Figure 8 , Figure 7 yes Figure 1 A magnified structural diagram at point C. Figure 8 This is a side view of the pin 16 provided in an embodiment of this application. In one embodiment, the hinge portion 14 includes the pin 16 and two lugs 112. The two ends of the pin 16 pass through the two lugs 112 respectively. The lugs 112 are respectively connected to two adjacent light source modules 10.

[0072] Specifically, the ear portion 112 is provided with a pin hole 1121, and the pin 16 is inserted into the pin hole 1121. The pin 16 and the pin hole 1121 are clearance-fitted.

[0073] For example, the diameter of the portion of the pin 16 that mates with the pin hole 1121 and the diameter of the pin hole 1121 are both uniformly 5 mm. Specifically, the basic diameter of the pin hole 1121 is 5 mm, with an upper deviation of 0.013 mm and a lower deviation of 0.0008 mm. The basic diameter of the portion of the pin 16 that mates with the pin hole 1121 is 5 mm, with an upper deviation of -0.008 mm and a lower deviation of -0.013 mm.

[0074] In this embodiment, the ears 112 of two adjacent light source modules 10 are hinged together by a pin 16, resulting in a simple hinge structure between the two ears 112 that is easy to assemble, thereby improving the assembly efficiency of the folding lamp 100.

[0075] Please see Figure 7 and Figure 8 In one embodiment, the end of the pin 16 protrudes through the ear 112. An annular groove 161 and a retaining ring 17 are located on the outer circumferential surface of the pin 16 protruding from the ear 112. The inner circumferential side of the retaining ring 17 is engaged in the annular groove 161.

[0076] It can be understood that the retaining ring 17 has an open structure. Specifically, both ends of the retaining ring 17 protrude outward along the radial direction of the retaining ring 17 to form outward protrusions, and through holes are provided on the outward protrusions. Thus, when installing or removing the retaining ring 17, the two tips of needle-nose pliers can be inserted into the through holes of the two outward protrusions, thereby enlarging the opening of the retaining ring 17 by manipulating the needle-nose pliers, so as to realize the installation and removal of the retaining ring 17.

[0077] In this embodiment, the pin 16 can be detachably installed between two adjacent light source modules through the above-described configuration. This improves both the ease of assembly of the folding lamp 100 and the convenience of subsequent maintenance.

[0078] Please see Figure 10 , Figure 10 This is a schematic diagram of the internal structure of the folding lamp 100 provided in an embodiment of this application. In one embodiment, the pin 16 has a hollow structure 162 and two first wire holes 163. The two first wire holes 163 are located at both ends of the pin 16. One end of each first wire hole 163 is connected to the hollow structure 162. A wire 19a is provided between the electric light sources 13 of two adjacent light source modules 10. The two ends of the wire 19a are connected to the two adjacent electric light sources 13 respectively. The middle part of the wire 19a passes through the ear portion 112, the first wire hole 163, and the hollow structure 162. In this way, the wiring of the folding lamp 100 is neat and the wiring is clear. In addition, by placing the wires 19a of each electric light source 13 inside the folding lamp 100, the wires 19a can be prevented from affecting the flatness of the surface of the folding lamp 100, thereby improving the stability of the folding lamp 100 when placed and its folding performance.

[0079] Specifically, the two first wire holes 163 of each pin 16 are arranged at a radial distance along the pin 16, that is, the two first wire holes 163 of each pin 16 are arranged symmetrically along the center point of the hollow structure 162, so as to facilitate the laying of the wire 19a on the pin 16.

[0080] Specifically, a second wire hole 1122 is provided in the ear portion 112, and two first wire holes 163 are respectively connected to the second wire holes 1122 on two adjacent ear portions 112. The end of the second wire hole 1122 away from the first wire hole 163 is connected to the adjacent mounting cavity 18.

[0081] It can be understood that one end of the wire 19a is connected to the electric light source 13 of a light source module 10, and the other end passes through the second wire hole 1122 on one ear 112, a first wire hole 163, a hollow structure 162, another first wire hole 163 and another second wire hole 1122 on the ear 112 in sequence before being inserted into the mounting cavity 18 of another light source module 10 and connected to its electric light source 13.

[0082] It is understood that the power cord 19 can be connected in parallel with each wire 19a, or the wires 19a can be connected in series to the power cord 19. The power cord 19 delivers power to the light source 13 through the wires 19a to drive the light source 13 to emit light.

[0083] For example, the thickness of the pin 16 is 1.5 mm and its inner diameter is 2 mm.

[0084] Please see Figure 9 , Figure 9 yes Figure 8 A cross-sectional view of DD. In one embodiment, the other end of each first wire hole 163 extends circumferentially along the pin 16. The central angle α corresponding to the first wire hole 163 in the circumferential direction of the pin 16 satisfies: 180°<α≤270°. Along the axial direction of the pin 16, the two first wire holes 163 partially overlap.

[0085] It can be understood that the central angle α corresponding to the first hole 163 around the pin 16 is, but is not limited to: 183°, 190°, 192°, 196°, 198°, 205°, 210°, 213°, 220°, 223°, 226°, 234°, 241°, 250°, 267°, 270°.

[0086] It is understandable that the dimensions of the first wire hole 163 in the circumferential direction of the pin 16 can be adjusted according to the usage requirements and the strength of the pin 16, so that the setting of the first wire hole 163 is conducive to the folding and unfolding of the light source module 10, and can also ensure the structural strength of the pin 16, so as to meet the usage strength of the folding lamp 100.

[0087] It is understandable that the two first wire holes 163 partially overlap along the axial direction of the pin 16, which is beneficial for the two adjacent light source modules 10 to fit together when folded.

[0088] In this embodiment, the above-described configuration prevents the portion of the wire 19a located between the pin 16 and the ear 112 from being squeezed and worn when the light source module 10 rotates relative to the pin 16, and also prevents the portion of the wire 19a located between the pin 16 and the ear 112 from obstructing the rotation of the light source module 10. This improves the smoothness of unfolding and folding the folding lamp 100. Furthermore, it prevents the central angle α corresponding to the first wire hole 163 in the circumferential direction of the pin 16 from being too large, which could lead to low strength of the pin 16 and thus improve the structural reliability of the pin 16.

[0089] In one embodiment, the number of light source modules 10 is 5 to 12.

[0090] It is understandable that the number of light source modules 10 in the folding lamp 100 can be 5, 6, 7, 8, 9, 10, 11 or 12.

[0091] Specifically, the folding lamp 100 has eight light source modules 10. This allows each light source module 10 to have a large light-emitting area while keeping the folding lamp 100 small in size after folding, making it easy to carry.

[0092] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
