[0005] To solve the above-mentioned technical problems, the present invention provides a battery assembly comprising: a housing, a battery cell, two conductive elements, and an insulating element. The housing has a connected receiving cavity and two conductive through holes. The battery cell is received in the receiving cavity. One end of one of the conductive elements is connected to the positive electrode of the battery cell, and one end of the other conductive element is connected to the negative electrode of the battery cell. The other ends of the two conductive elements extend out of the receiving cavity from the two conductive through holes respectively. The insulating element is disposed in the housing and covers the portion of the conductive elements extending out of the receiving cavity.

[0019] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0021] This application provides a battery assembly 100; please refer to [link / reference]. Figures 1 to 3The battery assembly 100 includes: a housing 1, a battery cell 2, two conductive elements 3, and an insulating element 4. The housing 1 has a connected receiving cavity 11 and two conductive through holes 12. The battery cell 2 is housed in the receiving cavity 11. One end of each of the two conductive elements 3 is electrically connected to the positive and negative terminals of the battery cell 2, respectively. One end of one conductive element 3 is connected to the positive terminal of the battery cell 2, and one end of the other conductive element 3 is connected to the negative terminal of the battery cell 2. The other ends of the two conductive elements 3 extend out of the receiving cavity 11 from the two conductive through holes 12. The insulating element 4 is disposed on the housing 1 and covers the portion of the conductive elements 3 extending out of the receiving cavity 11. At least a portion of the insulating element 4 corresponding to the conductive elements 3 can be opened to provide an opening for external electrical contact devices to enter the receiving cavity 11 and establish an electrical connection with the conductive elements 3. Through the above method, this application can rely on the addition of the insulating element 4 to cover the two conductive elements 3 between the insulating element 4 and the housing 1. The conductive elements 3 can only communicate with the external environment through the opened opening, thereby reducing the risk of contact between external conductive foreign objects and the conductive elements 3 and avoiding short circuits between the two conductive elements 3.

[0022] It should be noted that the aforementioned "opening that can be opened to allow external electrical contact devices to enter the receiving cavity 11 and establish an electrical connection with the conductive element 3" refers to the perforated structure between the battery assembly and the external electrical contact device. One type is an opening structure that is directly exposed to the external environment, such as a battery assembly where the insulation is directly exposed to the external environment. Such battery assemblies require support or protection from the housing structure of the electrical contact device. The other type is an opening structure that is received and hidden in a cavity or compartment and can only be accessed by passing through the cavity opening or compartment opening, such as a battery rod. Specifically, the battery rod includes a shell, a battery cell, two conductive elements, and an insulating element. The shell is provided with a receiving compartment, and the battery cell, two conductive elements, and insulating element are... All components are housed within a receiving compartment, which has an opening that communicates with the external environment. One end of one of the conductive components is connected to the positive terminal of the battery cell, and one end of the other conductive component is connected to the negative terminal of the battery cell. An insulating component is disposed within the receiving compartment and can divide the receiving compartment into two areas: a first area for supplying power to the battery cell and conductive components, and a second area for external electrical contact devices (such as e-cigarette cartridges) to be inserted and mated. The insulating component also has two hole structures, through which the two conductive components can communicate with the second area. When an external electrical contact device is connected to the battery rod, it needs to pass through the slot of the receiving compartment into the second area and then contact the two conductive components through the two hole structures.

[0023] Understandably, the insulating component 4 can also seal the aforementioned receiving cavity or containment chamber, preventing leakage into the receiving cavity or containment chamber when external electrical contact devices containing liquid matrix are connected to the battery assembly. Specifically, in battery assemblies with open structures directly exposed to the external environment, the protruding electrical contact structure on the external electrical contact device, which is electrically connected to the conductive element, can seal the hole structure when the battery assembly is connected to the external electrical contact device; in battery rods housed and hidden in cavities or containments that require passing through the cavity opening or the containment opening to reach, this insulating component built into the containment chamber can seal the first and second regions when the battery rod is connected to the external electrical contact device, preventing liquid matrix from seeping into the first region when external electrical contact devices containing liquid matrix, such as smoke cartridges, are connected to the battery rod.

[0024] Understandably, there is a distance between the end face of the conductive element 3 away from the housing 1 and the surface of the insulating element 4 away from the housing 1. That is, along the direction from the cell 2 toward the conductive element 3, the end face of the conductive element 3 is lower than the surface of the insulating element 4. This is so that when an external conductive foreign object is connected to the battery assembly 100, it can first contact the insulating element 4. If the conductive foreign object wants to conduct electricity with the conductive element 3, it needs to contact the insulating element 4 before accurately inserting into the conductive through hole 12 to contact the conductive element 3. By reducing the communication area between the conductive element 3 and the external environment and extending the path of electrical connection between the conductive foreign object and the conductive element 3, the probability of contact between the external conductive foreign object and the conductive element 3 is reduced, thereby reducing the risk of short circuit of the conductive element 3.

[0025] It should be noted that the insulating element 4 may be made of materials including but not limited to silicone, rubber, plastic, etc. For example, in this embodiment, the insulating element 4 is preferably made of silicone.

[0026] In some embodiments, please refer to Figure 4The insulating component 4 is provided with two connecting holes 41 corresponding to the two conductive components 3. The two conductive components 3 communicate with external devices through the two connecting holes 41. At least one elastic arm 42 extends radially from the inner wall of the connecting hole 41. The elastic arm 42 shields at least a portion of the connecting hole 41. Understandably, the area of ​​the connecting hole 41 shielded by the elastic arm 42 can be selected according to actual needs, such as one-third, one-half, or all of it, so that the area of ​​the conductive component 3 exposed to the external environment through the connecting hole 41 is smaller than that without the elastic arm 42, further reducing external conductive interference. The probability of an object contacting the conductive element 3 is such that the elastic arm 42 can generate elastic deformation and move towards or away from the conductive element 3. This allows the exposed and protruding conductive structure (such as a terminal or conductive post) on the external electrical contact device to push the elastic arm 42 to generate elastic deformation when the external electrical contact device needs to be electrically connected to the battery assembly 100. This allows the conductive structure to extend into the connecting hole 41 and connect to the conductive element 3, ensuring that the battery assembly 100 can normally supply power to the external electrical contact device.

[0027] Furthermore, a gap space 421 is left between the elastic arm 42 and the conductive element 3. The gap space 421 is used to provide space for the elastic deformation of the elastic arm 42. Along the center line direction of the connecting hole 41, the width of the gap space 421 needs to be greater than the displacement distance required for the elastic arm 42 to undergo elastic deformation, so as to ensure that the elastic arm 42 can return to its original state (i.e., the state of shielding the connecting hole 41) when there is no external force.

[0028] Understandably, the number of elastic arms 42 is a positive integer greater than or equal to one. For example, in this embodiment, the number of elastic arms 42 is four. The four elastic arms 42 are arranged circumferentially around the connecting hole 41. The four elastic arms 42 together close the connecting hole 41, so that when the protruding conductive structure of the external electrical contact device pushes the elastic arm 42 to move, the distance displaced by the elastic arm 42 is shorter than when it is pushed by a single elastic arm 42. This can reduce the width of the spacing space 421 along the central axis of the connecting hole 41 and improve the integration of the battery assembly 100.

[0029] In some embodiments, please refer to Figure 4Each of the four elastic arms 42 has a clearance notch 422 at one end away from the wall of the connecting hole 41. The clearance notches 422 of the four elastic arms 42 form a guide hole 423. The conductive component 3 communicates with the external environment through the guide hole 423. The guide hole 423 is used to guide the conductive structure of the external electrical contact device through the insulating component and then contact the conductive component. That is, it forms a guide when the device is inserted into the connecting hole 41, which is beneficial to the elastic deformation of the elastic arm 42. In addition, the presence of the guide hole 423 can also work with the four elastic arms 42 to form a limiting constraint on the conductive structure, thereby improving the stability of the conductive structure when it is inserted into the connecting hole 41.

[0030] In some embodiments, please refer to Figure 4 Along the circumference of the connecting hole 41, a deformation gap 424 is provided between any two adjacent elastic arms 42. The deformation gap 424 is connected to the guide hole 423 to ensure that the elastic arm 42 can undergo elastic deformation smoothly. This deformation gap 424 is used by the conductive structure of the external electrical contact device to reduce interference between two adjacent elastic arms 42 when pushing the elastic arm 42 to undergo elastic deformation, thereby improving the smoothness of the elastic arm 42 during elastic deformation.

[0031] In some embodiments, please refer to Figure 5 and Figure 6 The housing 1 is provided with a receiving groove 13, and two conductive through holes 12 are located at the bottom of the receiving groove 13. The insulating member 4 is received in the receiving groove 13. The side wall of the receiving groove 13 limits the insulating member 4 to prevent the insulating member 4 from undergoing unexpected displacement.

[0032] Understandably, the insulating component 4 is not limited to being accommodated by the receiving groove 13. The insulating component 4 can also be connected to the housing 1 by means of snap-fit, screw-fit, elastic sleeve, etc.

[0033] In some embodiments, please refer to Figure 2 The surface of the insulating component 4 facing away from the receiving groove 13 is flush with the opening of the receiving groove 13, so as to improve the aesthetics of the insulating component 4 installed in the receiving groove 13 and reduce the accelerated aging of the insulating component 4 caused by external foreign objects hitting the insulating component 4.

[0034] It is understandable that the electrical connection between the conductive component 3 and the battery cell 2 can be, but is not limited to, direct connection via welding or other means, or movable connection.

[0035] For example, in some preferred embodiments, please refer to Figure 6The conductive element 3 adopts a spring-loaded movable connection. Specifically, the conductive element 3 includes a movable part 31 and an abutting part 32 connected to each other. The diameter of the movable part 31 is smaller than the diameter of the abutting part 32 to form a first abutting step 33. The battery assembly 100 includes an elastic element 5, which is sleeved on the movable part 31. One end of the elastic element 5 abuts against the housing 1, and the other end of the elastic element 5 abuts against the abutting part 32, that is, the other end of the elastic element 5 abuts against the first abutting step 33. The elastic element 5 is used to provide elastic force for the conductive element 3. When the external electrical contact device is electrically connected to the battery assembly 100, the conductive structure of the external electrical contact device pushes the conductive element 3 to move towards the battery cell. The elastic element 5 is compressed and provides a continuous elastic resistance force to the conductive element 3, thereby enabling the conductive element 3 to maintain a tight and reliable physical contact with the conductive structure and avoiding poor contact between the conductive structure and the conductive element 3. The elastic element 5 can always provide an outward contact force to the conductive element. When the battery assembly 100 and the external electrical contact device are subjected to vibration or impact, the elasticity of the elastic element 5 can play a buffering role, absorbing this energy and preventing the electrical connection between the battery assembly 100 and the external electrical contact device from being broken. Furthermore, the elastic element 5 can improve the self-alignment tolerance capability between the battery assembly and the external electrical contact device, improve the compatibility and adaptability of the battery assembly 100 with external electrical contact devices with conductive structures of different lengths.

[0036] In some embodiments, please refer to Figure 6 The housing 1 is provided with a sliding groove 14, and a conductive through hole 12 is located at the bottom of the sliding groove 14. The conductive element 3 is slidably disposed in the sliding groove 14. One end of the elastic element 5 abuts against the bottom of the sliding groove 14, and the other end of the elastic element 5 abuts against the abutting part 32 (i.e., the other end of the elastic element 5 abuts against the first abutting step 33). The sliding groove 14 is configured to constrain the conductive element 3 to form a radial limit on the conductive element 3, so as to prevent the conductive element 3 from shaking when sliding in the sliding groove 14, which would affect the smoothness of the movement of the conductive element 3.

[0037] It should be noted that when the battery assembly 100 is not connected to an external electrical contact device, a portion of the contact portion 32 of the conductive member 3 extends into the sliding groove 14, so that the conductive member 3 can slide smoothly in the sliding groove 14 when pushed by an external force, thus avoiding the contact portion 32 of the conductive member from contacting the opening of the sliding groove 14 and the edge of the housing and causing jamming.

[0038] In some embodiments, please refer to 7. The battery cell 2 includes a battery pack 21, a power connection terminal 22, and a connecting wire 23. One end of the connecting wire 23 is connected to the battery pack 21, and the other end of the connecting wire 23 is connected to the power connection terminal 22. It is understood that there are two power connection terminals 22 and two connecting wires 23. The two power connection terminals 22 are respectively connected to the positive and negative terminals of the battery pack 21 through the two connecting wires 23. The power connection terminal 22 is fixed to the periphery of the conductive through hole 12, and the power connection terminal 22 is provided with a insertion groove 221. The insertion groove 221 communicates with the conductive through hole 12 so that the moving part 31 of the conductive member 3 can pass through the conductive through hole 12 and be inserted into the insertion groove 221 of the power connection terminal 22. The moving part 31 is fixedly connected to the power connection terminal 22 to ensure that the part of the abutment 32 can always be extended into the sliding groove 14.

[0039] Understandably, the length of the exposed moving part 31 between the electrical terminal 22 and the contact part 32 is the maximum stroke that the conductive member 3 can slide in the sliding groove 14.

[0040] It should be noted that the moving part 31 always maintains contact with the inner wall of the insertion groove 221, thereby ensuring a stable electrical connection between the conductive element 3 and the battery cell 2. The end face of the moving part 31 away from the abutting part 32 abuts against the bottom of the insertion groove 221, thereby maximizing the contact area between the conductive element 3 and the electrical terminal 22, ensuring that the battery assembly 100 can output a large power supply current to the external electrical contact device, and reducing the risk of local overheating of the battery assembly 100.

[0041] In some embodiments, please refer to Figure 1 The housing 1 includes a frame portion 1b and a main body portion 1a. Conductive through holes 12 and receiving grooves 13 are both provided on the frame portion 1b. The main body portion 1a and the frame portion 1b are detachably connected. Specifically, one of the main body portion 1a and the frame portion 1b is provided with a snap-fit ​​portion 1b1, and the other with a latch 1a1. The snap-fit ​​portion 1b1 snaps into the latch 1a1, thereby achieving a detachable connection between the main body portion 1a and the frame portion 1b. Exemplarily, in this embodiment, the main body portion 1a is provided with a latch 1a1, the frame portion 1b is provided with a snap-fit ​​portion 1b1, and the main body portion 1a is also provided with a receiving groove. The battery cell 2 is received in the receiving groove. When the snap-fit ​​portion 1b1 snaps into the latch 1a1, the frame portion 1b blocks the receiving groove, thus jointly enclosing and forming the aforementioned receiving cavity 11. Through the detachable connection between the frame portion 1b and the main body portion 1a, the battery cell 2 can be replaced, facilitating the maintenance and replacement of the battery assembly.

[0042] This application also provides a power supply 200, please refer to [link / reference]. Figure 8The power supply 200 includes a circuit board assembly 201, a power supply housing 202, and the aforementioned battery assembly 100. The power supply housing 202 is provided with a receiving cavity 2021, in which at least a portion of the circuit board assembly 201 and the aforementioned battery assembly 100 are housed. The circuit board assembly 201 is provided with two conductive terminals 2011, which correspond to two connecting holes 41. The conductive terminals 2011 pass through the insulating member 4 and then contact the conductive member 3. Specifically, when the power supply 200 is connected to the battery assembly 100, the two conductive terminals 2011 pass through the two connecting holes 41 and abut against the two conductive members 3. As the length of the conductive terminals 2011 extending into the connecting holes 41 increases, the conductive terminals 2011 push the conductive members 3 to slide along the sliding groove 14 until the power supply 200 and the battery assembly 100 are assembled. The conductive members 3 are pushed by the conductive terminals 2011 to connect electrically with the battery cell 2, thereby completing the electrical connection between the atomizer 200 and the battery assembly 100.

[0043] In some embodiments, please refer to Figure 8 The power supply housing 202 is provided with a slot 2022, and the outer surface of the outer shell of the battery assembly 100 (i.e. the outer side wall of the frame part 1b) is provided with a hook 15. When the atomizer 200 is connected to the battery assembly 100, the hook 15 is received in the slot 2021, and at this time, the conductive terminal 2011 pushes the conductive member 3 to connect with the battery cell 2.

[0044] It should be noted that the specific structure and function of the battery assembly 100 are described in the above embodiments, and will not be repeated here.

[0045] This application also provides an electronic atomizing device 1000, please refer to [link / reference]. Figure 8 The electronic atomizing device 1000 includes an atomizer 300 and the aforementioned power supply 200, with the atomizer 300 electrically connected to the power supply 200.

[0046] This application provides a battery assembly 100, a power supply 200, and an electronic atomizing device 1000, including a housing 1, a battery cell 2, two conductive elements 3, and an insulating element 4. The housing 1 is provided with a connected receiving cavity 11 and two conductive through holes 12. The battery cell 2 is received in the receiving cavity 11. One end of each of the two conductive elements 3 is electrically connected to the positive and negative terminals of the battery cell 2, respectively. The other ends of the two conductive elements 3 extend out of the receiving cavity 11 from the two conductive through holes 12, respectively. The insulating element 4 is disposed on the housing 1 and covers the portion of the conductive elements 3 extending out of the receiving cavity 11. The insulating element 4 is provided with two connecting holes 41 corresponding to the two conductive elements 3. The two conductive elements 3 communicate with external devices through the two connecting holes 41. In the above manner, the present application can rely on the addition of insulating component 4 to cover two conductive components 3 between insulating component 4 and housing 1. The conductive component 3 can only communicate with the external environment through its corresponding connecting hole 41, thereby reducing the risk of contact between external conductive foreign objects and conductive component 3, avoiding short circuit between the two conductive components 3, and improving the safety of battery assembly 100 during use.

[0047] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
