Description

Technical Field

[0001] This utility model relates to the field of camera cleaning, and in particular to a camera device. Background Technology

[0002] In relatively enclosed environments such as tunnels, impurities such as car exhaust can accumulate on the camera lens, leading to a decrease in image quality. Therefore, cameras typically incorporate windshield wipers and a spray nozzle. The nozzle sprays water onto the wipers to allow them to clean the lens. However, as the wipers move continuously while the nozzle is spraying water, a significant portion of the water sprayed from the nozzle fails to reach the wipers, resulting in water waste.

[0004] A camera device includes a body and a nozzle, the nozzle being mounted on the body, the nozzle having a water spray hole located on the outside of the body, and a camera lens being disposed on the outer wall of the body, the axis of the water spray hole passing through the camera lens.

[0005] The axis of the water spray hole of this invention passes through the top edge of the imaging lens.

[0006] The camera device of this utility model also includes a windshield wiper, which is movably disposed on the outer wall of the device body for cleaning the imaging lens.

[0007] The wiper of this utility model includes a movable rod and a wiper blade, the wiper blade being mounted on the movable rod, and the movable rod being used to cause the wiper blade to press against the camera lens;

[0008] The wiper blade includes a body, a first elastic rib, a second elastic rib, and a third elastic rib. The first elastic rib, the second elastic rib, and the third elastic rib are arranged side by side on the body, and a reinforcing rib is provided between the second elastic rib and the third elastic rib.

[0009] In this invention, the roots of the first elastic rib and the roots of the second elastic rib are spaced apart, the reinforcing rib is located between the roots of the second elastic rib and the roots of the third elastic rib, and the heads of the second elastic rib and the heads of the third elastic rib are spaced apart from the reinforcing rib.

[0010] The camera device of this utility model also includes a water supply component, which includes a water tank and a water cover. The water tank is connected to the nozzle. The side wall of the water tank is provided with a water inlet. The water cover is provided with a venting groove. When the water cover is placed over the water inlet, the two ends of the venting groove are located inside the water tank and outside the water tank, respectively.

[0011] The water supply assembly of this utility model further includes a condensation module and a water collection funnel. The condensation module and the water collection funnel are installed on the water tank so that the condensation module can send condensate into the water tank through the water collection funnel.

[0012] The water supply component of this utility model further includes a water level monitoring unit, which is at least partially located inside the water tank.

[0013] The camera device of this utility model also includes a protective cover, which is fitted onto the body and forms a light-blocking groove with the outer wall of the body, and the shooting lens is located in the light-blocking groove.

[0014] The outer wall of the machine body of this utility model is also provided with a supplementary light lens, which is located in the light-blocking groove;

[0015] The light-blocking groove has a first sidewall and a second sidewall. The first sidewall is located on the side of the shooting lens away from the supplementary light lens, and the second sidewall is located on the side of the supplementary light lens away from the shooting lens. The depth of the light-blocking groove at the first sidewall is greater than the depth of the light-blocking groove at the second sidewall.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention relates to a camera device that alters the orientation of the water spray nozzle axis on the device body, allowing the nozzle axis to pass through the imaging lens. Since the relative position between the water spray nozzle and the imaging lens is fixed, the vast majority of the water sprayed from the nozzle directly reaches the imaging lens, achieving stable rinsing. In other words, the majority of the water sprayed from the nozzle effectively cleans the imaging lens, thereby reducing water waste. Attached Figure Description

[0046] Example 1:

[0047] See Figure 1 and Figure 2 This embodiment provides a camera device, including a body 1, a nozzle 2, and a windshield wiper 3.

[0048] The outer wall of the body 1 is provided with a shooting lens 11. Optionally, a supplementary lighting lens 12 may also be provided on the outer wall of the body 1. The specific functions and structures of the shooting lens 11 and the supplementary lighting lens 12 are existing technologies and will not be described in detail in this embodiment.

[0049] The wiper 3 is movably mounted on the outer wall of the body 1, and the wiper 3 can move in ways including but not limited to rotation or translation. The movable range of the wiper 3 at least covers the shooting lens 11, and preferably further covers the supplementary lighting lens 12, so as to allow the wiper 3 to clean the shooting lens 11 and the supplementary lighting lens 12.

[0050] In this embodiment, the windshield wiper 3 is rotatably mounted on the outer wall of the body 1.

[0051] The nozzle 2 is mounted on the body 1. See details. Figure 4 and Figure 5 The nozzle 2 has five water spray holes 21, which are located on the outside of the body 1 and can spray clean water. It is easy to understand that the direction of the clean water spray at the water spray holes 21 is roughly the axial direction of the water spray holes 21.

[0052] In existing technology, the axis of the water spray nozzle 21 and the windshield wiper 3 are generally located on the same plane to allow the water sprayed from the nozzle 21 to reach the windshield wiper 3. However, this embodiment's research found that during the water spraying process, because the windshield wiper 3 is in a constantly moving state while the position of the water spray nozzle 21 is fixed, a considerable amount of water cannot fall onto the windshield wiper 3. Furthermore, since the axis of the water spray nozzle 21 is generally parallel to the lens 11, the water that does not fall onto the windshield wiper 3 will not have a rinsing effect on the lens 11. In other words, a considerable amount of water falls below the body 1 without providing any cleaning effect, resulting in a significant waste of water.

[0053] To address the aforementioned technical issues, this embodiment alters the axial direction of the water spray hole 21, causing the axis of the water spray hole 21 to pass through the imaging lens 11. In other words, the vast majority of the clean water sprayed from the water spray hole 21 will directly reach the imaging lens 11, thereby directly rinsing the imaging lens 11.

[0054] Based on the differences, compared with the prior art, the camera device of this embodiment has at least the following advantages: First, since the relative position between the water spray hole 21 and the imaging lens 11 is fixed, the clean water sprayed from the water spray hole 21 can be directly and stably sprayed onto the imaging lens 11, thereby ensuring that most of the clean water at least plays a role in rinsing and cleaning the imaging lens 11, reducing water waste. Second, the water droplets on the surface of the imaging lens 11 will not fall too quickly due to tension and other reasons, so there is sufficient time for them to come into contact with the wiper 3. In other words, although the water spray hole 21 does not directly spray clean water onto the wiper 3, the wiper 3 can still maintain a wet state based on its reciprocating motion on the surface of the imaging lens 11, reducing damage to the imaging lens 11 caused by the wiper 3.

[0055] See details Figure 5 Preferably, the axis of the water spray hole 21 passes through the top edge of the imaging lens 11. Therefore, the water sprayed from the water spray hole 21 first reaches the top edge of the imaging lens 11. Under the action of gravity, this part of the water can slide down the surface of the imaging lens 11 to the bottom edge of the imaging lens 11, achieving the effect of cleaning the entire surface of the imaging lens 11 from top to bottom.

[0056] See Figures 2-5 Preferably, the nozzle 2 is provided with a baffle plate 22, and the water spray hole 21 is located between the baffle plate 22 and the imaging lens 11, so as to reduce the splashing of clean water at the water spray hole 21 into the non-target direction.

[0057] See Figure 1 and Figure 7 As a preferred embodiment, the camera device further includes a water supply component 4, an adapter component 6, and a protective sleeve 5.

[0058] A protective sleeve 5 is fitted onto the main body 1 to protect it. The main body 1 is mounted on the water supply assembly 4 via an adapter assembly 6. See also Figure 3 The nozzle 2 is provided with a water inlet connector 23, which is connected to the water supply component 4 so that the nozzle 2 can obtain water from the water supply component 4.

[0059] See Figures 7-9 The body 1 includes a front cover assembly 13 and a rear cover assembly 14. The front cover assembly 13 includes a front shell 131, a light panel 132, and a lens module 133. The rear cover assembly 14 includes a rear shell 141 and a water pump 142. The front shell 131 and the rear cover assembly 14 form a mounting cavity, within which the light panel 132 and the lens module 133 are located. The specific mating relationship between the front cover assembly 13 and the rear cover assembly 14 is also prior art.

[0060] The nozzle 2 and wiper 3 are located on the outer wall of the front housing 131, and the water pump 142 is mounted on the rear housing 141. In this embodiment, the maximum water pressure of the water pump 142 is 80 kPa, the radius of the water outlet of the water pump 142 is 0.6 mm, the transient pressure generated by the water pump 142 is approximately 0.09 N, the designed diameter of the spray nozzle 21 is 0.5 mm, and the actual water pressure at the spray nozzle 21 is P = 0.09 / [5π*(0.5*0.001)]. 2 The pressure is 0.23 MPa, which meets the normal operating requirements of nozzle 2.

[0061] See Figure 10 The adapter assembly 6 includes a cushioning foam 61, a sealing ring 62, an adapter 63, an adapter cover 64, and a connecting sheet metal 65. The adapter 63 is in close contact with the body 1 through the cushioning foam 61. The adapter cover 64 is mounted on the adapter 63, the adapter 63 is mounted on the connecting sheet metal 65, and the connecting sheet metal 65 is mounted on the water supply assembly 4.

[0062] See Figure 11 In this embodiment, the wiper 3 includes a movable rod 31 and a wiper blade 32. The wiper blade 32 is mounted on the movable rod 31, and the end of the movable rod 31 is hinged to the outer wall of the body 1. The wiper blade 32 is rotated by the movable rod 31.

[0063] Typically, a wiper blade 32 includes a body 321 and several elastic ribs. Both the body 321 and the elastic ribs extend axially along the movable rod 31, and the elastic ribs are usually integral with the body 321. The wiper blade 32 is usually made of rubber. The body 321 can be fixed to the movable rod 31 with screws. Each elastic rib has two side edges, which are the root and head of the rib, respectively. The root of the elastic rib is connected to the body 321, and the head of the elastic rib can slide on the surface of the imaging lens 11. During sliding, it compresses and deforms the surface of the imaging lens 11, using friction to clean the surface of the imaging lens 11.

[0064] See details Figure 12 and Figure 13 In this embodiment, there are three elastic ribs: a first elastic rib 322, a second elastic rib 323, and a third elastic rib 324. These three elastic ribs are arranged side by side on the body 321. When the wiper blade 32 slides on the surface of the lens 11, the movable rod 31 presses the wiper blade 32 against the surface of the lens 11, causing deformation of the heads of the first elastic rib 322, the second elastic rib 323, and the third elastic rib 324. The friction of the heads of the first elastic rib 322, the second elastic rib 323, and the third elastic rib 324 against the surface of the lens 11 achieves a cleaning effect.

[0065] It is particularly noteworthy that, in this embodiment, a reinforcing rib 325 is provided between the second elastic rib 323 and the third elastic rib 324.

[0066] See details Figure 14The solid lines represent the state of the heads of the first elastic rib 322, the second elastic rib 323, and the third elastic rib 324 before deformation, while the dashed lines represent the state of the heads of the first elastic rib 322, the second elastic rib 323, and the third elastic rib 324 after deformation. Due to the function of the reinforcing rib 325, the deformation of the heads of the second elastic rib 323 and the third elastic rib 324 is less than that of the head of the first elastic rib 322 during the sliding process on the surface of the imaging lens 11. In other words, the heads of the second elastic rib 323 and the third elastic rib 324 generate greater friction on the surface of the imaging lens 11, resulting in hard friction. The head of the first elastic rib 322 exerts less friction on the surface of the imaging lens 11, resulting in soft friction. Through the combination of hard and soft friction, the cleaning effect of the wiper blade 32 on different types of dirt on the surface of the imaging lens 11 is improved.

[0067] To prevent the deformation capacity of the first elastic rib 322 from being interfered with by the second elastic rib 323, the roots of the first elastic rib 322 and the roots of the second elastic rib 323 are spaced apart.

[0068] In addition, in order to prevent the deformation capacity of the head of the second elastic rib 323 and the head of the third elastic rib 324 from being too low, the reinforcing rib 325 can be set between the root of the second elastic rib 323 and the root of the third elastic rib 324, so that the head of the second elastic rib 323 and the head of the third elastic rib 324 are spaced apart from the reinforcing rib 325.

[0069] See Figure 1 , Figure 2 and Figure 6 In this embodiment, the protective sleeve 5 and the outer wall of the body 1 form a light-blocking groove 51. The shooting lens 11 and the supplementary light lens 12 are located in the light-blocking groove 51. The side wall of the light-blocking groove 51 can block stray light to reduce stray light entering the shooting lens 11.

[0070] Preferably, the sidewalls of the light-blocking groove 51 can be coated with black paint to absorb stray light.

[0071] In this embodiment, the imaging lens 11 is located above the supplementary lighting lens 12, and the light-blocking groove 51 has a generally square opening. The light-blocking groove 51 has a first sidewall 511 and a second sidewall 512, which are generally opposite to each other, with the first sidewall 511 located above the second sidewall 512. Simultaneously, the first sidewall 511 is located on the side of the imaging lens 11 furthest from the supplementary lighting lens 12, and the second sidewall 512 is located on the side of the supplementary lighting lens 12 furthest from the imaging lens 11. Therefore, the first sidewall 511 is relatively close to the imaging lens 11, while the second sidewall 512 is relatively far from the imaging lens 11. The imaging lens 11 mainly relies on the first sidewall 511 to reduce stray light entering.

[0072] See details Figure 6 Based on the above analysis, this embodiment optimizes the structure of the light-blocking groove 51 by appropriately reducing the depth of the light-blocking groove 51 at the second sidewall 512 (the width of the second sidewall 512 is shortened), so that the depth of the light-blocking groove 51 at the first sidewall 511 is greater than the depth of the light-blocking groove 51 at the second sidewall 512. Specifically, the depth of the light-blocking groove 51 at the first sidewall 511 is 'a', and the depth of the light-blocking groove 51 at the second sidewall 512 is 'b', i.e., a > b.

[0073] Since the primary method of blocking stray light is through the first sidewall 511, the reduction in the width of the second sidewall 512 does not significantly affect the blocking effect. However, the reduction in the width of the second sidewall 512 allows light emitted from the supplementary lens 12 in the c-direction to avoid being reflected by the second sidewall 512 to the imaging lens 11, thereby reducing the adverse effects on the image quality of the camera device.

[0074] Example 2:

[0075] Based on Embodiment 1, this embodiment further provides a specific structure of the water supply component 4.

[0076] See Figure 15 and Figure 16 The water supply assembly 4 includes a water tank 41 and a water cap 42. The water tank 41 is connected to the nozzle 2. A water inlet 411 is provided on the side wall of the water tank 41, through which water can be added to the water tank 41. The water cap 42 can be fastened to the water inlet 411 by a snap-fit ​​mechanism. When the water cap 42 is fastened to the water inlet 411, water evaporation from the water tank 41 is reduced.

[0077] See Figure 19 and Figure 20In this embodiment, a venting groove 421 is provided on the water cover 42. When the water cover 42 is closed at the water inlet 411, one end of the venting groove 421 is located inside the water tank 41, and the other end of the venting groove 421 is located outside the water tank 41, so that the air pressure inside the water tank 41 and the external atmospheric pressure are kept consistent.

[0078] The water cover 42 can also be connected to a fall-prevention ring 422, which is snapped onto the water tank 41 to prevent the water cover 42 from falling off the water tank 41.

[0079] See you again Figure 15 and Figure 16 In this embodiment, the water supply component 4 also includes a condensation module 43, a water collection funnel 44, and a dust filter. The condensation module and the water collection funnel are installed on the water tank 41. The condensation module can generate condensate, which drips onto the water collection funnel 44 and then enters the water tank 41 through the water collection funnel 44, thereby replenishing the water inside the water tank 41. The dust filter is installed on the top of the water collection funnel 44 to filter the condensate before it falls onto the water collection funnel 44.

[0080] Figure 17 and Figure 18 In this embodiment, the water supply component 4 also includes a water level monitoring unit 45, which is at least partially located inside the water tank 41 to monitor the water level inside the water tank 41 and thus determine whether the water tank 41 is short of water.

[0081] In this embodiment, the water tank 41 has a capacity of 2.6L. In actual testing in a tunnel scenario, the wipers clean the windshield twice a week, with each wiper cycle involving two round trips and a water spray volume of approximately 4ml. The water usage is approximately 8ml per week and approximately 32ml per month. Without considering water vapor evaporation, the clean water in the water tank 41 can be used for 6.5 years. This is suitable for achieving a long-lasting, controllable, and reliable self-cleaning mechanism in scenarios where manual cleaning is difficult.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
