Description

Technical Field

[0001] This invention relates to the field of lens modules, and in particular to a waterproof heated lens module. Background Technology

[0002] Lens modules are the core components in modern electronic devices that enable optical imaging.

[0003] In cold outdoor environments, frost or fog can form on the outer lens of a lens module, affecting its shooting performance. Especially in recent years, with the increasing use of cameras mounted on vehicles, images captured by these cameras are used for automatic braking and autonomous driving control, and the quality of these images can directly contribute to accidents. Therefore, the development of cameras capable of melting snow deposits on the front of lenses is becoming increasingly important. Traditional heated lens modules use heating elements on the outer lens to heat the lens for de-icing and defogging.

[0004] However, in traditional heated lens modules, the bonding effect between the heating element and the outer lens may be poor. Especially after long-term use, due to factors such as vibration and external force, gaps may form between the heating element and the outer lens, affecting the heat transfer effect. Furthermore, the heating element is generally located outside the outer lens, which can only heat one side, resulting in poor heating efficiency.

[0005] Currently, most optical imaging lenses with defogging or defrosting functions use heating elements of the setting sensor (NTC or PTC). However, in exposed environments, this can easily lead to inaccurate sensing and may even damage the heating element, and also requires waterproofing.

[0006] For example, Chinese patent document CN118859444A discloses a heated lens assembly, including an imaging lens assembly, a heater, and a lens barrel. The imaging lens assembly includes an inner lens assembly and an outer lens assembly. The outer lens assembly includes at least one outer lens; the heater is used to heat the imaging lens assembly and includes at least two parts. One of the at least two parts is in direct contact with the imaging lens assembly. The lens barrel is used to house the other of the at least two parts. The at least two parts of the heater include a non-heated area and a hot area of ​​the heating element. However, directly exposing the heater to the imaging lens assembly can have significant adverse consequences.

[0007] However, there is an urgent need for a heated lens assembly that can meet waterproof requirements, so that the heating element of the optical lens can effectively heat the outer lens, avoid the sensor from becoming loose or failing due to the heating process, and the sensor is not easily affected by the heat zone.

[0019] According to the present invention, the outer lens can be made of glass with a thermal conductivity between 0.5 (W·m). -1 ·K -1 )~1.5(W·m -1 ·K -1 Between 0.5 and 0.5 W·m. The other inner lenses of the lens group can be made of plastic, which is more cost-effective, as plastic lenses have a thermal conductivity of less than 0.5 W·m. -1 ·K -1 That is, the outer lens has a higher thermal conductivity than the other lenses in the lens group. The heating element effectively transfers heat to the object side (the outer side of the outer lens is the object side), which can effectively melt ice, snow, frost, etc. attached to the outer lens.

[0020] According to the present invention, a heating element that heats up when energized is provided inside the lens barrel and between the outer lens and the adjacent second lens of the lens group (the present invention uses four lenses as an example, but it can also have eight lenses, referred to sequentially as the outer lens, second lens, third lens, and fourth lens). Therefore, the overall size of the lens module is not increased, and the snow-melting function is achieved. Since there is no issue of unclear images due to snow or other deposits on the outer lens, the shooting performance of the lens module is effectively prevented from deteriorating.

[0021] According to the present invention, the overall heating section includes components such as a heating element, a heating insert, and a heating plate, and has an FPC (Flexible Printed Circuits) connector and connecting wire harness, a thermistor (integrated on the heating element or a spacer integrally connected to the heating element), etc. The FPC is a flexible substrate, and its material can be PET film or polyimide film, etc., which can be formed into a structure with circuits configured on the film. The heating element, the thermistor, and the FPC connecting wire harness and connector form a heating circuit and a thermistor circuit. The heating circuit and the thermistor circuit (wiring) use an impedance material with a predetermined resistance value and have the function of heating when energized. The heating circuit and the thermistor circuit can be formed by conventional screen printing of silver paste or carbon paste. To improve the accuracy of the circuit pattern, etching can be performed in the circuit pattern to form a structure of composite films such as copper foil, aluminum foil, and stainless steel foil bonded to the polyimide film.

[0022] A thermistor is a component with PTC (Positive Temperature Coefficient) function, where resistance increases dramatically with temperature, exhibiting a positive temperature coefficient. Thermistors have a roughly constant resistance value near room temperature, but their resistance rises sharply above a certain temperature. Thermistors are generally made by adding trace amounts of soil-like elements to barium titanate. The heating circuit and thermistor circuit are powered through an FPC (Flexible Printed Circuit) connector.

[0023] In an ultra-wide-angle lens, to ensure a horizontal viewing angle exceeding 180°, the distance (gap) between the outer lens and the second lens flange is preferably selected to be between 0.05mm and 0.5mm. If this distance exceeds 0.5mm, the horizontal viewing angle becomes less than 180°, making it difficult to achieve an ultra-wide angle. If the gap is less than 0.05mm, inserting the heating element becomes difficult. In this invention, the thickness of the heating element relative to the axial direction is selected to be approximately 0.2mm; if this distance is less than 0.5mm, it is difficult to ensure a horizontal viewing angle exceeding 180°.

[0024] The positive and progressive effects of this invention are as follows: According to the waterproof heated lens module of the present invention, by setting a third sealing ring, the outer lens presses against the third sealing ring in the installed state to provide a seal and achieve waterproofing. Furthermore, by setting an elastic pressure member, the outer lens compresses and deforms the elastic pressure member in the installed state, providing pressure to the heating element, ensuring the heating element adheres tightly to the outer lens and preventing separation or gaps. Further, by setting a heating insert, which is inserted into the second annular groove on the edge of the outer lens, the interior of the outer lens can be heated to improve the heating effect on the outer lens, thereby increasing heating efficiency and achieving rapid de-icing and defogging.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will understand that this description is exemplary and does not limit the present invention to the scope of the described embodiments.

[0037] like Figures 1-10 As shown, a waterproof heated lens module according to a specific embodiment of the present invention includes: a base 1 and a lens assembly disposed within the base 1; the lens assembly includes an outer lens 4 disposed on one side of the base 1; a third sealing ring 5, wherein a groove 101 is formed on one side of the base 1, and the third sealing ring 5 is disposed within the groove 101; one side of the outer lens 4 is embedded in the groove 101; a pressure cap 2, which is threadedly connected to the base 1; the pressure cap 2 is fitted onto the outer lens 4, and the pressure cap 2 presses against the side of the outer lens 4 away from the base 1. Along the edge, the outer lens 4 and the wall of the groove 101 are clamped together to form a third sealing ring 5; a heating element 7 is disposed in the groove 101, and an elastic pressing element is provided on the side of the heating element 7 away from the outer lens 4 so that the heating element 7 is tightly fitted to the side wall of the outer lens 4; a heating insert 8 is provided, and the number of heating inserts 8 is multiple, and the multiple heating inserts 8 are distributed in a ring array on the base 1; a second annular groove 401 extending into the outer lens 4 is provided on the peripheral surface of the outer lens 4, and the heating insert 8 is inserted into the second annular groove 401.

[0038] A third sealing ring 5 is provided to create a waterproof seal at the mounting position of the outer lens 4, preventing moisture from entering. This sealing ring 5 is an O-ring made of rubber.

[0039] The heating structure is designed to heat the outer lens 4, thereby de-icing and defogging. The heating element 7 heats the side wall of the outer lens 4, while the heating insert 8 is inserted into the interior of the outer lens 4 to heat the interior. This combination of methods ensures both heating effect and efficiency, thereby improving the de-icing and defogging efficiency of the outer lens 4.

[0040] like Figures 3-5 As shown, a second sealing ring 202 is installed on one side edge of the pressure cover 2. The second sealing ring 202 is tightly fitted to the wall of the seat body 1. The other side edge of the pressure cover 2 extends inward to form a pressure edge, and a first sealing ring 201 is provided on the pressure edge. The first sealing ring 201 is pressed to the edge of the outer lens 4 away from the seat body 1.

[0041] The first sealing ring 201 provides a seal between the pressure cap 2 and the side wall of the outer lens 4, while the second sealing ring 202 provides a seal between the pressure cap 2 and the base 1. Through the above structure, a first seal is provided for the sealing protection of the internal components of the lens module, and in conjunction with the second seal provided by the third sealing ring 5, the sealing and waterproofing effect is improved.

[0042] The seal provided by the first sealing ring 201 also provides waterproof protection for the heating insert 8 inside the pressure cap 2.

[0043] like Figure 3-5 As shown in Figures 9 and 10, the elastic pressure member includes a pressure ring 6; the seat body 1 has a first annular groove 104 communicating with the recess 101, the pressure ring 6 is fitted into the first annular groove 104, and the pressure ring 6 has a plurality of evenly distributed recesses 601 on one side of the pressure ring 6 located in the first annular groove 104. A first spring 602 is provided in the recesses 601, and the pressure ring 6 is elastically connected to the wall of the first annular groove 104 through the first spring 602. A stop post is fixedly installed on one side of the pressure ring 6 located in the first annular groove 104.

[0044] During the installation of the outer lens 4, while the outer lens 4 presses against the third sealing ring 5, it also pushes the heating element 7 and the pressure ring 6, causing the pressure ring 6 to move into the first annular groove 104 and compress the first spring 602. This causes the first spring 602 to deform until the stop post on the pressure ring 6 is in contact with the inner side of the first annular groove 104, thus blocking it from entering the correct position. Then, the pressure cap 2 is installed. After the outer lens 4 is installed, the compression force of the first spring 602 acts on the heating element 7 through the pressure ring 6, ensuring that the heating element 7 is tightly fitted against the side wall of the outer lens 4, thus guaranteeing the heating effect on the outer lens 4.

[0045] like Figure 5 As shown, it also includes an inflation component 10, the third sealing ring 5 is an inflation sealing ring, and the inflation component 10 is connected to the inflation sealing ring.

[0046] The inflation assembly 10 includes a movable seat 1001 and a piston 1003; one end of the movable seat 1001 is fixedly connected to the piston 1003, and a second inner groove 1002 penetrating the piston 1003 is opened in the movable seat 1001. A third spring 1004 is provided in the second inner groove 1002. An air chamber 105 is connected to one side of the first annular groove 104. The piston 1003 is fitted into the air chamber 105. The movable seat 1001 is elastically connected to the wall of the air chamber 105 through the third spring 1004, and one end of the movable seat 1001 extends into the first annular groove 104. An air supply channel is provided in the seat body 1, and the air supply channel is connected to the third sealing ring 5 and the air chamber 105.

[0047] The air supply channel consists of a first connecting hole 106 opened in the base 1, a second connecting hole 108 opened in the base 1, and a connecting pipe 107. The first connecting hole 106 communicates with the air chamber 105. The third sealing ring 5 is provided with a socket 501, which is inserted into the second connecting hole 108 to realize the communication between the air chamber 105 and the third sealing ring 5. A stop seat 1005 is fixedly installed in the air chamber 105.

[0048] With the above design, when the outer lens 4 is installed, in addition to pressing the third sealing ring 5, the inflation component 10 also inflates the third sealing ring 5 to further improve the sealing effect.

[0049] The inflation assembly 10 operates as follows: the pressure ring 6 moves into the first annular groove 104 and approaches the movable seat 1001, pushing the movable seat 1001 and the piston 1003 together to move deeper into the air chamber 105 and compress the third spring 1004. At the same time, it pushes the gas in the air chamber 105. The gas passes through the first connecting hole 106, the connecting pipe 107, the second connecting hole 108 and the socket 501 in sequence and enters the third sealing ring 5, thereby inflating the third sealing ring 5.

[0050] When the outer lens 4 is disassembled, the pressure ring 6 loses pressure, and the first spring 602 causes the pressure ring 6 to move outward from the first annular groove 104, releasing the pressure on the movable seat 1001. The movable seat 1001 moves inward into the first annular groove 104 by the elastic force of the third spring 1004 until the piston 1003 and the stop seat 1005 are in contact. During the movement of the piston 1003, the air chamber 105 is drawn inward. The gas in the third sealing ring 5 flows back into the air chamber 105 after passing through the inlet 501, the second connecting hole 108, the connecting pipe 107 and the first connecting hole 106 in sequence.

[0051] like Figure 4 and Figure 7As shown, the heating plug 8 includes a heating plate 801; the heating plate 801 is fixedly connected to a slide rod 804 via a connecting strip 803, the slide rod 804 is slidably connected to a slide groove 109 opened on the base 1, a first inner groove 805 is opened in the slide rod 804, a second spring 806 is provided in the first inner groove 805, the slide rod 804 is elastically connected to the wall of the slide groove 109 via the second spring 806, and a plug 807 is fixedly installed at the end of the slide rod 804 away from the connecting strip 803, and the plug 807 is electrically connected to the heating plate 801.

[0052] The base 1 has a storage groove 110 and a guide hole 111. The heating insert 801 is slidably sleeved with the guide hole 111. When the heating insert 801 is inserted into or pulled out of the second annular groove 401 on the outer lens 4, the guide hole 111 provides guidance for the movement of the heating insert 801. When the heating insert 801 is inserted into the second annular groove 401, the connecting strip 803 and the part of the heating insert 801 connected to the connecting strip 803 are stored in the storage groove 110, that is, the storage groove 110 serves to provide storage space.

[0053] A ball head seat 802 is fixedly installed on one end of the heating insert plate 801 connected to the connecting strip 803, and the end of the ball head seat 802 away from the heating insert plate 801 is provided with a spherical surface. The pressure cover 2 is provided with a conical part, and the inner diameter of the conical part of the pressure cover 2 gradually decreases in the direction away from the threaded seat 3. The inner wall of the conical part of the pressure cover 2 is in contact with the spherical surface of the ball head seat 802.

[0054] like Figure 4 As shown, the base 1 has a second passageway 103 communicating with the slide groove 109. A second connecting wire harness 9 is inserted into the second passageway 103. The second connecting wire harness 9 is connected to a socket 902. The socket 902 is located at the end of the slide groove 109 and is aligned with the plug 807. The second connecting wire harness 9 is connected to a second connection port 901. A waterproof adhesive filling layer 11 is provided in the second passageway 103 to seal the second passageway 103.

[0055] When the entire lens module is in use, the second connector 901 connects to external power supply and control components.

[0056] Place the outer lens 4 into the recess 101 and press it down so that the outer lens 4 presses against the third sealing ring 5. Maintain the pressed state of the outer lens 4, and then install the pressure cap 2. When the outer lens 4 is pressed down, the stop post on the pressure ring 6 is in contact with the inner wall of the first annular groove 104 and is blocked, while the second annular groove 401 is aligned with the guide hole 111. When the pressure cap 2 is not installed, if... Figures 8-10As shown, the heating plate 801 extends to the outside of the base 1. The heating plate 801 is not inserted into the groove 101, so as not to affect the outer lens 4 being embedded and pressed into the groove 101.

[0057] After the outer lens 4 is pressed into the groove 101, the cover 2 is installed. The cover 2 presses the ball head seat 802 through the inner wall of its conical part, causing the ball head seat 802 and the heating plate 801 to move. The movement is guided by the guide hole 111, so that the heating plate 801 is inserted into the second annular groove 401. At the same time, the heating plate 801 drives the slide rod 804 to move together through the connecting bar 803. The slide rod 804 moves into the slide groove 109 and compresses the second spring 806. At the same time, the plug 807 is inserted into the socket 902.

[0058] When the outer lens 4 is removed and replaced, the pressure cap 2 is removed, and the ball head seat 802 loses the pressure limit of the pressure cap 2. Through the compression force of the second spring 806, the heating plate 801 is moved away from the second annular groove 401, so as not to obstruct the subsequent removal of the outer lens 4.

[0059] With the above design, when installing the cover 2, all heating plates 801 can be automatically inserted into the second annular groove 401, and when the cover 2 is removed, all heating plates 801 can be automatically pulled out from the second annular groove 401, which facilitates the replacement of the outer lens 4.

[0060] like Figure 3 and Figure 6 As shown, the heating element 7 is connected to a first connecting harness 701. The first connecting harness 701 passes through a first channel groove 102 formed on the base 1. The first connecting harness 701 is connected to a first connecting port 702. A waterproof adhesive filling layer 11 is provided in the first channel groove 102 to seal the first channel groove 102. The waterproof adhesive filling layer 11 is made of thermosetting waterproof black adhesive for sealing.

[0061] In practical implementation, the first connection port 702 is connected to external power supply and control components.

[0062] Both the heating element 7 and the heating plate 801 employ a combination structure of heating wire and thermistor. The thermistor is used for temperature measurement and control.

[0063] like Figure 3 and Figure 8 As shown, an internal thread is provided on one inner wall of the pressure cap 2, and a threaded seat 3 is fixedly installed on the seat 1. The threaded seat 3 is provided with an external thread, and the internal thread of the pressure cap 2 is connected to the external thread of the threaded seat 3. The above-mentioned threaded structure is designed for the threaded connection between the pressure cap 2 and the seat 1.

[0064] like Figure 8As shown, the pressure cap 2 is flared, with a pressure edge and an internal threaded part on each side, and a tapered part in the middle; the inner diameter of the internal threaded part is the same as the inner diameter of the tapered part at its maximum position.

[0065] When the entire lens module is used as a lens for a photography or video recording device, the side of the base 1 away from the outer lens 4 is glued to the outer shell with thermosetting waterproof black adhesive, and the outer shell provides protection and sealing for that side of the base 1; before the base 1 is installed with the outer shell, the first connection port 702 and the second connection port 901 are connected.

[0066] The first connection port 702 and the second connection port 901 use an FPC interface for connection.

[0067] In summary, the present invention has been described in detail through specific embodiments. Those skilled in the art will understand that the present invention is not limited to the above embodiments, and various changes or modifications can be made to these embodiments. Regardless of any changes in their shape or structure, such changes and modifications should fall within the protection scope of the present invention without departing from the principles and essence of the present invention.
