It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1-10, an embodiment of the present invention discloses a camera, which includes a case body, a package portion 300, and a sensor board 410.

The case body and the package portion 300 are connected, the case body and the package portion 300 are used as a housing of the camera, and the case body and the package portion 300 can be connected in a non-detachable connection manner such as welding, or can be detachably connected by means of a threaded connection member.

Specifically, the respective structures of the housing body and the encapsulating portion 300 can be determined according to actual conditions, taking the structure formed by the housing body and the encapsulating portion 300 as a cubic structure as an example, optionally, the encapsulating portion 300 can be a flat-plate structure, the housing body can be a surrounding structure, and the housing body is only provided with an opening, and the encapsulating portion 300 can be installed at the opening; alternatively, the case body may be a flat plate-shaped structural member, and the sealing portion 300 is provided with an opening, and the case body may be mounted at the opening. Still alternatively, the case body and the packing part 300 each include a plurality of plate-shaped structures, the plurality of plate-shaped structures are connected to each other, and the case body and the packing part 300 are connected to form a housing of the camera. It should be noted that, the structural composition of the case body and the sealing portion 300 is described only by the general structure of the case body and the sealing portion 300, the specific structural composition of the case body and the sealing portion 300 is not determined to be a regular flat plate structure, each part of the case body and the sealing portion 300 may be an approximately flat plate structure, and the surfaces of the case body and the sealing portion 300 may be provided with other structures such as protrusions or recesses.

Moreover, the housing body and the packaging part 300 enclose a containing cavity, the sensor board 410 is arranged in the containing cavity, and the housing body and the packaging part 300 can provide protection and packaging functions for the sensor board 410 to prevent the sensor board 410 from being damaged. The size and shape of the receiving cavity may be selected according to the shape and size of the sensor board 410, for example, if the sensor board 410 is a rectangular structural member or an approximately rectangular structural member, the receiving cavity may also be a cubic structure, and if the sensor board 410 is a circular structural member, the receiving cavity may also be a circular structure.

Of course, the camera may further include other components, such as a power board 510, an interface board 520, and an FPGA (Field Programmable Gate Array) board, and the power board 510, the interface board 520, and the FPGA board 530 are disposed in the accommodating cavity, and shapes and sizes of the three may be selected according to the shape and size of the sensor board 410, so that the overall shape of the housing formed by the housing body of the camera and the packaging portion 300 is relatively regular, and the overall size of the camera is reduced. In addition, if there are relatively many components to be mounted on the power board 510, two or more power boards 510 may be disposed, and the power boards 510 are connected to each other and connected to the sensor board 410, so as to ensure that the overall size of the camera is still relatively small. The interface board 520 is provided with an interface through which power can be supplied to the camera, and information interaction between external equipment and the camera can be realized through the interface, and the interface board 520 is connected with the power board 510. The FPGA board 530 is connected to the sensor board 410, and the worker can program the camera according to an actual situation, so that the working condition of the camera meets a preset requirement.

The shell body is provided with a light inlet, objects outside the camera can emit or reflect light rays to enter the camera through the light inlet, and the light rays are received by the sensor 420 on the sensor plate 410, of course, the sensor 420 needs to be arranged opposite to the light inlet, the sensor 420 is arranged in the stress center of the sensor plate 410, and the stress center of the sensor plate 410 is used as a reference point of the sensor 420. The shape and size of the light entrance hole may be determined according to the shape and size of the sensor 420 and the interval between the sensor 420 and the light entrance hole. The sensor board 410 is fixed to the case body by a fixing member 430 so that the sensor board 410 can be fixedly coupled to the case body.

In order to ensure that the temperature drift effect can be applied to the camera as weakly as possible during the use of the camera, the fixing member 430 may alternatively be a point-shaped structural member, for example, the fixing member 430 may be a bolt connector, and may also be a rivet or a pin. In the case that the fixing members 430 are point-shaped structural members, the number of the fixing members 430 is at least three, the sensor board 410 is fixed to the case body by the at least three fixing members 430, and a force-receiving center of a pattern formed by connecting lines between the at least three fixing members 430 coincides with a force-receiving center of the sensor board 410.

The sensor plate 410 is fixed by the at least three fixing pieces 430 at the same time, so that the at least three fixing pieces 430 can provide deformation restraint for the sensor plate 410 at the same time, and in the process that the sensor plate 410 deforms due to the change of the temperature of the sensor plate 410, the deformation amount of the sensor plate 410 from the stress center to the direction of the at least three fixing pieces 430 is basically consistent, so that even if the sensor plate 410 deforms in a certain range, the stress center of the sensor plate 410 can be ensured to be basically located at the initial position, the reference point of the sensor 420 cannot be changed basically, the imaging measurement result of the sensor 420 is prevented from being changed, and the accuracy of the camera is ensured to be higher all the time.

Specifically, the number of the fixing members 430 in the shape of a dotted structure may be three, four, or more, and taking the number of the fixing members 430 as three as an example, the three fixing members 430 may be distributed at the vertex of a triangle, and the force center of the triangle formed by connecting the three fixing members 430 is overlapped with the force center of the sensor board 410, wherein the force center of the triangle is generally the center of gravity of the triangle. Accordingly, in the case where the number of the fixing members 430 is four, the connecting lines between the four fixing members 430 may form a rectangular structure or a parallelogram structure. It should be noted that, since the fixing members 430 have a certain volume, in the process of determining the pattern formed by the connecting lines among at least three fixing members 430, each fixing member 430 may be represented by a point where the force-receiving center of each fixing member 430 is located.

In another embodiment of the present application, the fixing element 430 may also be a strip-shaped structural element, for example, the fixing element 430 may be a strip-shaped glue layer formed by nailing or glue, and a force center of a pattern formed by connecting lines between end points of the plurality of fixing elements 430 or a force center of a pattern surrounded by straight lines where the plurality of fixing elements 430 are located coincides with the force center of the sensor board 410.

In the case where the fixing member 430 is a bar structure, the number of the fixing members 430 may be two, three, four, or more, the sensor board 410 is fixed to the case body by a plurality of fixing members 430, and the plurality of fixing members 430 may each provide a deformation restriction to a deformation direction of the sensor board 410. In the process that the sensor plate 410 is deformed due to the temperature change of the sensor plate, if the number of the fixing members 430 is two, the amount of deformation of the sensor plate 410 from the force receiving center thereof to the direction of the four end points of the two fixing members 430 is substantially in a fixed proportion to the distance between each of the four end points and the force receiving center. If the number of the fixing pieces 430 is three or more, the deformation amount of the sensor plate 410 from the stress center to the straight line where each fixing piece 430 is located is basically in a fixed proportion to the distance between the straight lines and the stress center, so that even if the sensor deforms to a certain degree, the deformation amount of the sensor plate 410 to each direction can be basically consistent, the stress center of the sensor plate 410 is still basically located at the initial position, the reference point of the sensor plate 420 is basically not changed, the imaging measurement result of the sensor plate 420 is prevented from being changed, and the accuracy of the camera is always high.

Specifically, when the number of the fixing pieces 430 is two, the two fixing pieces 430 are arranged oppositely, and the distance between the two fixing pieces and the force-receiving center of the sensor board 410 can be equal, so as to ensure that the force-receiving center of the graph formed by the connecting lines between the four end points of the two fixing pieces 430 can coincide with the force-receiving center of the sensor board 410; of course, under the condition that the lengths of the two fixing members 430 are different, even if the distance between the two fixing members 430 and the force-receiving center of the sensor board 410 is not equal, the force-receiving center of the graph formed by the connecting lines between the four end points of the two fixing members 430 can be ensured to coincide with the force-receiving center of the sensor board 410. In the case that there are at least three fixing members 430, the positions of the at least three fixing members 430 may be determined according to the specific number of the fixing members 430, and in addition, in order to ensure that the fixing effects provided by the fixing members 430 are substantially the same, the lengths of the fixing members 430 may be made equal, and the connection conditions between the case body and the sensor board 410 and the fixing members 430 may be made correspondingly the same.

In addition, because other components may be disposed on the sensor board 410, or the weights of different unit areas on the sensor board 410 may be different, the stress center of the sensor board 410 may not be the center of gravity of the sensor board 410, and in the actual application process, the stress center of the sensor board 410 may be determined according to the specific situation of the sensor board 410, so that when the temperature of the sensor board 410 changes, it is ensured that the deformation degrees generated in different directions at different positions on the sensor board 410 relative to the stress center of the sensor board 410 are substantially the same, that is, the deformation degrees are related to the relative position relationship between the positions of the different positions and the stress center, and are unrelated to the direction in which the different positions are located in the stress center.

Alternatively, the fixing member 430 may also be a closed ring-shaped structural member, in the case that the fixing member 430 is a closed ring-shaped structural member, the number of the fixing member 430 may be one, the fixing member 430 is disposed at the edge of the sensor plate 410, and the force center of the fixing member 430 is made to coincide with the force center of the sensor plate 410, which may also ensure that the deformation amount generated from the force center to each direction is substantially the same in the deformation process of the sensor plate 410.

Alternatively, each fixing member 430 is a threaded connecting member, that is, the fixing member 430 is a point-shaped connecting member, at least three through holes 411 are formed in the sensor board 410, and each fixing member 430 passes through one through hole 411 and extends into the housing body, so as to fixedly connect the sensor board 410 to the housing body. Specifically, mounting 430 can be bolt assembly, and the screw rod passes from one side of sensor board 410, and stretches into this internal, can set up the through-hole on the casing correspondingly, and the nut can set up the one side that deviates from sensor board 410 at the casing, and perhaps, the nut also can bury underground in the casing to guarantee that screw rod and nut can form stable fixed connection, provide reliable constraint effect for sensor board 410.

Further, the fixing member 430 is a screw, a threaded hole 130 is formed in a side of the case body facing the sensor board 410, and the fixing member 430 penetrates through the side of the sensor board 410 and extends into the threaded hole 130, and forms a reliable fixed connection relationship with the threaded hole 130. Under the condition of adopting above-mentioned technical scheme, the part quantity in the camera is less, and can simplify the structure of shell body, reduces the packaging efficiency of camera, can also guarantee that mounting 430 is located shell body, prevents to influence mounting 430's fixed effect because of mounting 430 contacts or collides with external object.

Alternatively, in the case where the number of the fixing members 430 is three, in order to further enhance the constraint effect provided by the three fixing members 430 on the sensor board 410, a triangle defined by connecting lines between the three fixing members 430 may be an equilateral triangle. Accordingly, when the number of the fixing members 430 is larger, the pattern formed by the plurality of fixing members 430 may be a regular pattern such as a rectangle or a regular pentagon as much as possible, thereby enhancing the effect of the constraint action on the sensor board 410.

In addition, the number of the fixing members 430 in the shape of a dot-shaped structure may be determined according to the specific shapes of the sensor board 410 and the case body, so as to ensure that each fixing member 430 can be stably installed on the sensor board 410 and the case body, and the force center of the graph formed by connecting lines between at least three fixing members 430 coincides with the force center of the sensor board 410. For example, the sensor board 410 and the case body are both of a hexagonal structure, the number of the fixing members 430 may be three or six, etc., which may ensure that each fixing member 430 can be stably coupled to the sensor board 410 and the case body.

The fixing member 430 is a point-shaped connecting member, and the sensor plate 410 is a rectangular structural member, the number of the fixing member 430 may be three or four, the processing difficulty of the sensor plate 410 having a rectangular structure is relatively low, and the overall space utilization efficiency of the sensor plate 410 is also relatively high, under the condition that the number of the fixing member 430 is three or four, it can be ensured that the fixing member 430 can provide a reliable fixing effect for the sensor plate 410, and it is prevented that the reference points of the sensor are deviated due to different deformation amplitudes in different directions when the sensor plate 410 is deformed, and it is also possible to make the overall assembly difficulty of the camera relatively low, and it is possible to prevent that the overall structural strength of the sensor plate 410 and the housing body is greatly adversely affected due to the excessive hole-shaped structures arranged on the sensor plate 410 and the housing body.

As described above, in the case where the number of the fixing members 430 is three, the figure formed by connecting the three fixing members 430 may be an equilateral triangle; in the case where the number of the fixing members 430 is four, the connecting lines between the plurality of fixing members 430 may be formed in a rectangular or diamond shape, etc., according to the specific size of the sensor board 410. It should be noted that, it is within the scope of the present application that the outer edge of the sensor may not be a regular rectangular structure due to the structure such as the notch or the hole provided at the position such as the edge of the sensor plate 410 having the rectangular structure, and as long as the overall structure of the sensor plate 410 is approximately rectangular, the sensor plate 410 may be considered as a rectangular structural member.

As described above, the fixing member 430 may also be a bar-shaped structural member, and optionally, the fixing member 430 is a bar-shaped adhesive layer, so that a stable fixed connection relationship can be formed between the sensor board 410 and the case body by providing a plurality of bar-shaped adhesive layers between the sensor board 410 and the case body in the process of assembling the sensor board 410 and the case body. With the above technical solution, the difficulty of assembling the housing body and the sensor board 410 is relatively small, and the connection area between the sensor board 410 and the housing body can be increased, thereby further restricting the deformation amplitude of the sensor board 410.

More specifically, the actual number of the fixing members 430 may be correspondingly selected according to the structures of the sensor board 410 and the case body to ensure that each fixing member 430 can be stably connected with the sensor board 410 and the case body. For example, the sensor board 410 has a triangular structure, the number of the fixing members 430 may be three, and three fixing members 430 are respectively attached to three sides of the sensor board 410.

In the case where the fixing member 430 is a strip-shaped structural member, optionally, the length of any fixing member 430 is greater than half of the length of the side of the sensor board 410 where the fixing member 430 is located, that is, half of the length of the side of the sensor board 410 is less than the length of the fixing member 430 on the side, in this case, the fixing member 430 can provide a strong restraining effect for the sensor board 410 to deform in the length direction of the fixing member 430.

Moreover, any fixing member 430 can be arranged in the center, that is, any fixing member 430 is arranged in the center at the side of the fixing member 430, so that the fixing member 430 can provide a stronger deformation restraining effect for the middle area of the sensor board 410, and further, the probability that the reference point is offset when the sensor 420 with the reference point being the stressed center of the sensor board 410 is deformed by the sensor board 410 is smaller.

Alternatively, the sensor board 410 is a rectangular structure, and the fixing members 430 are disposed on at least one set of opposite sides of the sensor board 410, that is, the number of the fixing members 430 may be two or four, the fixing members 430 are grouped in pairs, and two opposite fixing members 430 are respectively connected to two opposite sides of the sensor board 410.

In the case that the number of the fixing members 430 is two, the two fixing members 430 which are oppositely arranged may be parallel to each other, which makes the action positions of the two fixing members 430 providing the constraint on the corresponding side edges similar, and further makes the constraint action provided by the two fixing members 430 on each position on the sensor board 410 more uniform, thereby further improving the uniformity of the deformation amount of the sensor board 410 in each direction when deformed by the temperature change.

In the case that the number of the fixing members 430 is four, two opposite fixing members 430 may be parallel to each other, so that the acting positions of the constraint provided by any two opposite fixing members 430 in the four fixing members 430 on the corresponding side edges are similar, and the uniformity of the constraint action of the four fixing members 430 on any position on the sensor board 410 is further improved.

Further, the lengths of the two fixing members 430 disposed opposite to each other may be equal, in which case, the lengths of the regions where the two fixing members 430 provide the constraint for the corresponding side edges are also substantially equal, which may further converge the constraint effects provided by the two fixing members 430 disposed opposite to each other for the two side edges of the sensor board 410, respectively, so as to further improve the uniformity of the deformation amount of the sensor board 410 generated in each direction when the temperature changes. Accordingly, in the case where four fixing members 430 are fixed to the sensor board 410, the lengths of any two fixing members 430 disposed opposite to each other are equal.

Meanwhile, in a direction perpendicular to the two oppositely disposed fixing members 430, the two fixing members 430 may be disposed in parallel and level, in this case, a figure surrounded by a connecting line between end points of the two fixing members 430 is a rectangle, and a figure surrounded by straight lines where the four fixing members 430 are located is also a rectangle, which are the same as the shape of the sensor board 410, so that the deformation constraint effect of the plurality of fixing members 430 on the sensor board 410 may be further improved.

During use of the camera, the camera is usually mounted on a mounting base by means of a mounting bracket. Generally, the mounting surface of the camera is usually the bottom surface thereof, since the mounting surface of the camera can be usually locked on the mounting bracket by means of a threaded connector, and since the sensor board 410 needs a plurality of fixing members 430 to be fixed on the housing body, and in order to prevent the mounting bracket from shielding the camera, the light-entering side of the camera is usually located on a different side surface from the mounting surface of the camera, when the housing body of the camera and the package 300 are also deformed due to temperature change in the case that the mounting surface of the camera is in the fixed state, since only one side of the surface of the housing body where the sensor board 410 is fixed is in the fixed state near the mounting surface, the deformation amount generated to the side near the mounting surface is necessarily smaller than the deformation amount generated to the side away from the mounting surface in the process of the deformation of the portion of the housing body where the sensor board 410 is fixed, so that the deformation amount generated to the different directions of the portion of the housing body where the sensor, causing the force center of the sensor plate 410 to move, which also causes the reference point of the sensor to shift.

Further, in the camera disclosed in the embodiment of the present invention, the housing body includes a first housing 100 and a second housing 200, the first housing 100 is provided with a light inlet, and the sensor board 410 is fixed on the first housing 100. Second casing 200 includes that first enclosing keeps off 210, and first enclosing keeps off 210 and first casing 100 perpendicular and adjacent setting, that is, first enclosing keeps off 210 and has the installation face of camera, and at the installation camera in the in-process of installing support, first enclosing keeps off 210 and installing support adjacent, and first enclosing keeps off 210 and installing support and can not all shelter from the light direction that advances of camera, guarantees that the camera has better field of vision.

Moreover, one side of the first casing 100, which is away from the first enclosure 210, is provided with two first connection holes 110, the encapsulation portion 300 is provided with two second connection holes 340, the two second connection holes 340 are in one-to-one correspondence with the two first connection holes 110 and correspond to two connection pieces, and each connection piece can pass through one second connection hole 340 and extend into one corresponding first connection hole 110, so as to achieve the purpose of fixedly connecting the casing body and the encapsulation portion 300.

Meanwhile, one side of the case body, which is located on the first enclosure 210, is provided with two third connection holes 120, a stress center of a graph formed by connecting lines between the two third connection holes 120 and the two first connection holes 110 coincides with a stress center of the sensor board 410, the first enclosure 210 is provided with two fourth connection holes 230, the two fourth connection holes 230 correspond to the two third connection holes 120 one to one, and in the process of installing the camera, the first case 100 may be fixedly connected to the second case 200 through two connection pieces which pass through the fourth connection holes 230 and extend into the third connection holes 120.

In addition, the second housing 200 is also fixedly connected with the packing part 300, so that several parts in the housing of the camera can be fixedly connected as a whole. Under the condition of adopting the technical scheme, in the process that the first shell 100 deforms due to temperature change, the first shell 100 is restrained by the two first connecting holes 110 and the two third connecting holes 120, and the stress center of the graph formed by the connection lines between the two first connecting holes 110 and the two third connecting holes 120 is overlapped with the stress center of the sensor board 410, so that even if the first shell 100 deforms, the deformation of the first shell 100 from the stress center of the sensor board 410 to each direction is basically the same as much as possible, the reference point of the sensor can still be basically kept unchanged under the condition that the first shell 100 deforms, and the imaging measurement accuracy of the camera is improved.
