Description

[Technical field]

[0001] The invention relates to an oil-isolating circuit board storage structure and a solar push rod, belonging to the technical field of industrial photothermal solar push rods. [Background technology]

[0002] The main working principle of an electric push rod, also generally called a linear actuator, is to drive a transmission screw to rotate through a motor. A nut is set on the transmission screw, and when the transmission screw rotates, the nut is driven to reciprocate.

[0003] With the continuous development of solar energy technology, solar energy technology and electric push rods are combined with each other. At present, there are solar push rods on the market, and solar push rods are generally equipped with circuit boards, which are mainly used to feedback information and control the Hall card to ensure the normal operation of the push rod. However, there are certain shortcomings in the existing solar push rods. During the use of the solar push rod, the internal circuit board will be soaked in oil, and the circuit board will produce a capillary effect, which will affect the circuit board and make it unable to correctly feedback information and control the Hall card to close. Therefore, the solar push rod will not work properly, which will reduce the user experience. In addition, it takes a lot of time to solve the problems with the internal circuit board, which will also bring great inconvenience to the user. At the same time, it will also affect the service life of the solar push rod and increase the user's expenses in this regard. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is to provide a circuit board storage structure that can isolate oil, which can separate the circuit board from the oil and minimize the possibility of the circuit board generating a capillary effect.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A circuit board storage structure that can be isolated from oil, the structure is arranged in an outer tube of a solar push rod, the outer tube is also provided with a circuit board, the outer tube is provided with a through hole that penetrates the outer tube along the axial direction, the outer tube wall is provided with a cavity for storing the circuit board, and the cavity and the through hole are isolated from each other.

[0007] The beneficial effects of adopting the present invention are:

[0008] In the present invention, a cavity for storing a circuit board is provided on the wall of the outer tube, wherein the cavity is isolated from the through hole of the outer tube. During use, the circuit board is stored in the cavity. Since the cavity is isolated from the through hole of the outer tube, the oil in the through hole will not flow into the cavity, and the circuit board will not come into contact with the oil. Therefore, the possibility of a capillary effect between the circuit board and the oil will be greatly reduced. The present invention can protect the circuit board and avoid as much as possible the circuit board from being unable to provide information feedback and control the Hall switch due to the capillary effect. The present invention can provide a certain guarantee for the normal operation of the solar push rod and reduce the probability of failure of the solar push rod.

[0009] In addition, in the present invention, since the cavity isolates the contact between the circuit board and the oil, the possibility of circuit board failure can be reduced, and at the same time, it provides a guarantee for the normal use of the solar push rod, thereby reducing the user's maintenance of the solar push rod and improving the use efficiency of the solar push rod. Secondly, since the number of times the solar push rod needs to be repaired is significantly reduced, it can also avoid the solar push rod from being damaged due to disassembly and assembly during the maintenance process, which can increase the service life of the solar push rod, reduce the user's expenses in this regard, and bring a better experience effect to the user, allowing the user to use it with more confidence.

[0010] Preferably, the cavity passes through the outer tube, the penetration direction of the cavity is the same as the penetration direction of the through hole, and the length of the cavity is the same as the length of the outer tube, so that the circuit board can be placed at any position of the cavity, which greatly facilitates the circuit board to transmit signals.

[0011] Preferably, a first limit bar and a second limit bar are respectively provided at both ends of the circuit board for limiting the axial movement of the circuit board along the outer tube. The first limit bar and the second limit bar can limit the axial movement of the circuit board along the outer tube to prevent the circuit board from shaking and displacing during operation or transportation, resulting in poor contact signals, or the circuit board collides with the inner wall of the cavity and causes damage.

[0012] Preferably, the cross-sectional sizes of the first limit strip and the second limit strip match the cross-sectional size of the cavity, and the first limit strip and the second limit strip fill the space at both ends of the circuit board in the cavity, which can further ensure that the circuit board is isolated from external oil and improve the protection of the circuit board.

[0013] Preferably, a mounting seat and a front end cover are respectively provided at both ends of the outer tube, and both ends of the first limit strip are respectively in contact with the fixing seat and the circuit board, and both ends of the second limit strip are respectively in contact with the front end cover and the circuit board, so that the first limit strip, the second limit strip and the circuit board are fixed, which can prevent the circuit board from shaking during operation or transportation.

[0014] Preferably, the first limiting strip and the second limiting strip are aluminum strips.

[0015] Preferably, the cross-section of the cavity is rectangular as a whole, and grooves are provided on both sides of the cavity for limiting the radial movement of the circuit board along the outer tube, which can further prevent the circuit board from shaking during operation or transportation.

[0016] Preferably, the size of the cavity matches the size of the circuit board, and the cavity is only used to store the circuit board.

[0017] Preferably, the outer tube is provided with a cover for limiting the line from escaping from the cavity.

[0018] The present invention also shows a solar push rod, comprising an outer tube and a circuit board, wherein the outer tube is provided with the circuit board storage structure capable of isolating oil as described in any one of the above items.

[0019] Other features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0029] Embodiment 1:

[0030] like Figures 1 to 4 As shown, this embodiment shows an oil-isolated storage structure for a circuit board 3, wherein the structure is arranged in an outer tube 1 of a solar push rod, wherein the circuit board 3 is also arranged in the outer tube 1, wherein the outer tube 1 is provided with a through hole which penetrates the outer tube 1 axially, and wherein a cavity 2 for storing the circuit board 3 is provided on the wall of the outer tube 1, and the cavity 2 is isolated from the through hole.

[0031] In this embodiment, a cavity 2 for storing the circuit board 3 is provided on the wall of the outer tube 1, wherein the cavity 2 is isolated from the through hole of the outer tube 1. During use, the inner wall of the outer tube 11 needs to be matched with high and low temperature grease. However, since the high and low temperature grease is very easy to be in liquid state during operation, a large amount of grease will exist on the inner wall of the outer tube 11. The circuit board 3 is stored in the cavity 2. Since the cavity 2 is isolated from the through hole of the outer tube 1, the oil in the through hole will not flow into the cavity 2, and the circuit board 3 will not contact the oil. Therefore, the possibility of the circuit board 3 and the oil generating a capillary effect will be greatly reduced. This embodiment can protect the circuit board 3 and avoid as much as possible the circuit board 3 being unable to provide information feedback and control the Hall switch due to the capillary effect. This embodiment can provide certain guarantees for the normal operation of the solar push rod and reduce the probability of failure of the solar push rod.

[0032] In addition, in this embodiment, since the cavity 2 isolates the contact between the circuit board 3 and the oil, the possibility of failure of the circuit board 3 can be reduced, and at the same time, it provides a guarantee for the normal use of the solar push rod, thereby reducing the user's maintenance of the solar push rod and improving the efficiency of the use of the solar push rod. Secondly, since the number of times the solar push rod needs to be repaired is significantly reduced, it can also avoid the solar push rod from being damaged due to disassembly and assembly during the maintenance process, which can increase the service life of the solar push rod, reduce the user's expenses in this regard, and bring a better experience effect to the user, allowing the user to use it with more confidence.

[0033] In order to be able to place the circuit board 3 at will, the cavity 2 in this embodiment passes through the outer tube 1, and the penetration direction of the cavity 2 is the same as the penetration direction of the through hole. Therefore, the storage position of the circuit board 3 can be set as needed, so as to adjust the circuit board 3 to the best position for transmitting signals. Therefore, this embodiment can improve the stability of signal transmission, and can also bring more options for the assembly of the solar push rod and reduce its assembly difficulty.

[0034] It should be noted that, in other embodiments, the size of the cavity 2 may also match the size of the circuit board 3, and the cavity 2 is only used to store the circuit board 3. In addition, the outer tube 1 is also provided with a cover for limiting the circuit board 3 from leaving the cavity 2. The advantage of this embodiment is that the circuit board 3 has a small moving space, and in the absence of other objects, the circuit board 3 will not deviate or collide significantly. The circuit board 3 is restricted by the cavity 2 itself, and the cavity 2 can be isolated from the outside world by the cover, so that the protection of the circuit board 3 is more complete. Secondly, this structure can make the disassembly and assembly of the circuit board 3 simpler and more convenient, which is convenient for later maintenance.

[0035] In order to limit the arbitrary movement of the limiting plate in the cavity 2, the first limit strip 4 and the second limit strip 5 for limiting the axial movement of the circuit board 3 along the outer tube 1 are respectively provided at both ends of the circuit board 3 in this embodiment. The vibration generated during operation or transportation of this embodiment will cause the circuit board 3 to move axially along the outer tube 1, and the first limit strip 4 and the second limit strip 5 cooperate with each other to clamp the circuit board 3 between the two, so as to limit the axial movement of the circuit board 3, so as to avoid the poor signal reception caused by the movement of the circuit board 3 due to vibration, thereby affecting the normal operation of the solar push rod. In addition, it can also avoid the damage of the circuit board 3 caused by the collision of the circuit board 3 with the inner wall of the cavity 2 due to excessive vibration amplitude, so the first limit strip 4 and the second limit strip 5 also protect the circuit board 3.

[0036] In addition, in this embodiment, the cross-sectional sizes of the first limit strip 4 and the second limit strip 5 match the cross-sectional size of the cavity 2. When the first limit strip 4 and the second limit strip 5 sandwich the circuit board 3, the first limit strip 4 and the second limit strip 5 fill the space at both ends of the circuit board 3, which can further prevent external oil from entering the space where the circuit board 3 is located and contacting the circuit board 3.

[0037] In order to further limit the movement of the circuit board 3, the two ends of the outer tube 1 in this embodiment are respectively provided with a mounting seat and a front end cover, the two ends of the first limit strip 4 are respectively in contact with the fixing seat and one end of the circuit board 3, and the two ends of the second limit strip 5 are respectively in contact with the front end cover and the other end of the circuit board 3. The first limit strip 4, the second limit strip 5 and the circuit board 3 are squeezed and fixed by the mounting seat and the front end cover, which can further limit the axial movement of the circuit board 3 along the outer tube 1. In addition, in this embodiment, the first limit strip 4 and the second limit strip 5 are both aluminum strips. Of course, it can be understood that in other embodiments, the first limit strip 4 and the second limit strip 5 can also be composed of other materials.

[0038] In order to limit the radial movement of the circuit board 3 along the outer tube 1, Figure 2As shown, the cross-section of the cavity 2 described in this embodiment is rectangular as a whole. Since the overall size of the circuit board 3 is fixed, it is a flat long board as a whole, and various protruding elements are provided on the board surface. Therefore, there is space in the cavity 2 for accommodating elements in the radial direction of the outer tube 1. In order to prevent the circuit board 3 from moving in the radial direction, grooves for accommodating the circuit board 3 are provided on both sides of the cavity 2 described in this embodiment. Under the action of the grooves, the circuit board 3 cannot move along the radial direction of the outer tube 1. Therefore, it can be avoided that the circuit board 3 moves due to vibration and causes poor signal reception, affecting the normal operation of the solar push rod. In addition, it can also prevent the circuit board 3 from colliding with the inner wall of the cavity 2 due to excessive vibration amplitude, causing damage to the circuit board 3. Therefore, the grooves on both sides of the cavity 2 also protect the circuit board 3. It should be noted that the above-mentioned cross-sectional shape is the shape presented in the side view of the outer tube 1, as shown in FIG. Figure 2 shown.

[0039] Embodiment 2:

[0040] A solar push rod is shown in this embodiment, which includes an outer tube 1 and a circuit board 3, wherein the outer tube 1 is provided with a circuit board 3 storage structure that can isolate oil as described in Example 1 or other identical embodiments, and the circuit board 3 is stored in the above structure. This embodiment can isolate the circuit board 3 from the oil in the inner wall of the outer tube 1, thereby preventing the circuit board 3 from having a capillary effect due to being immersed in oil, thereby affecting the information feedback of the circuit board 3 and the control of the Hall switch, causing the solar push rod to fail to work normally. This embodiment provides a certain guarantee for the normal operation of the solar push rod, and can improve its working efficiency and service life.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
