Technical Field

[0001] The present invention relates to the technical field of rail transit equipment, and particularly to an optoelectronic conversion equipment box for the trackside and a trackside optoelectronic conversion equipment. Background Art

[0002] The statements in this part merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Currently, for vehicle communication, instructions need to be sent from the machine room and the trackside equipment performs actions. Among them, the trackside optoelectronic conversion equipment can realize the conversion of remote optical signals into electrical signals and centrally control the equipment at the trackside.

[0004] The traditional form of the trackside optoelectronic conversion equipment relies on an outdoor large cabinet. This optoelectronic conversion equipment is installed and integrated in the cabinet. A cement base is designed at the trackside and the large cabinet is installed on the base. However, such a traditional equipment form makes the optoelectronic conversion equipment inconvenient to install, consumes a lot of manpower and material resources during installation, and increases the cost. At the same time, since this optoelectronic conversion equipment is installed and integrated in the cabinet, the traditional optoelectronic conversion equipment cannot conveniently change the equipment position according to actual application requirements. In view of the above defects, the present invention has made improvements. Summary of the Invention

[0005] In order to overcome the deficiencies of the background art, the present invention provides an optoelectronic conversion equipment box for the trackside and a trackside optoelectronic conversion equipment. A modular optoelectronic conversion equipment box is adopted, the volume and weight of the box are reduced, and at the same time, the box also has waterproof and heat dissipation functions, making the optoelectronic conversion equipment an independent outdoor equipment, which is light and low-cost, and can be installed and relocated at any time, thus better meeting the actual application requirements.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An optoelectronic conversion equipment box for the trackside, the box includes two shells, the two shells are detachably connected and a waterproof rubber ring is arranged at the connection part, and the connection parts of the detachable connection are all located outside the waterproof rubber ring. An installation cavity is formed between the two shells, and a heat dissipation structure for natural heat dissipation is also arranged on the shell.

[0008] Further,

[0009] The detachable connection is a threaded connection. A plurality of inwardly protruding connection platforms are arranged around the shell, and a connection hole for threaded connection is arranged in the middle of the connection platform. Each connection hole is located outside the waterproof rubber ring.

[0010] Further,

[0011] The cross-section of the waterproof rubber ring is U-shaped. Two protruding first sealing parts are arranged on one side of the waterproof rubber ring, and a second sealing part is arranged on the other side. Two first sealing grooves adapted to the first sealing parts are arranged on one of the shells, and a second sealing groove adapted to the second sealing part is arranged on the other shell.

[0012] Further,

[0013] The bottom of the box body is detachably connected with a bracket, and all plugs or sockets for external connection on the box body are arranged at the bottom of the box body.

[0014] Further,

[0015] A circuit board is fixedly arranged inside the box body. The heat dissipation structure includes a heat dissipation boss arranged on the inner side of the shell. The surface of the heat dissipation boss is closely attached to the heat generating devices on the circuit board. The heat dissipation structure further includes a heat dissipation groove arranged on the outer side surface of the shell. The heat dissipation groove is located outside the heat dissipation boss, and heat dissipation fins are arranged in the heat dissipation groove.

[0016] Further,

[0017] Two circuit boards are arranged. A plurality of connecting columns are arranged on the inner sides of the two shells. The circuit boards are fixedly arranged on the connecting columns, and a heat dissipation cavity is formed between the two circuit boards.

[0018] Further,

[0019] The heat dissipation structure further includes heat dissipation fins, and a plurality of the heat dissipation fins are uniformly arranged on the outer surface of the shell.

[0020] Further,

[0021] The shell is integrally formed by aluminum alloy.

[0022] Further,

[0023] One rotary storage handle is arranged at the top of each of the two shells, and a storage groove adapted to the rotary storage handle is arranged on the shell.

[0024] A trackside optoelectronic conversion device includes a device body and further includes the optoelectronic conversion device box body as described above. The device body is arranged inside the optoelectronic conversion device box body.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The modular optoelectronic conversion device box body is adopted, the volume and weight of the box body are reduced, and at the same time, the box body also has waterproof and heat dissipation functions, so that the optoelectronic conversion device can be an outdoor device alone, which is light and low in cost, and can be installed and relocated at any time, thus better meeting the actual application requirements;

[0027] 2. Each connection hole is located outside the waterproof rubber ring, and the connection hole itself does not penetrate the inside of the housing, which can better form a closed installation cavity between the two housings, so that better sealing and waterproofing can be achieved.

[0028] 3. The seal between the two housings uses a waterproof rubber ring with a U-shaped cross-section. This structural design effectively increases the sealing surface, can achieve better sealing, and is beneficial to enhancing the waterproof performance of the box body.

[0029] 4. The surface of the heat dissipation boss is closely attached to the surface of the heat generating device. In this way, the heat generated by the heat generating device will be transferred to the entire housing through heat conduction, so that the heat generating device can effectively dissipate heat. The outer side of the heat dissipation boss is concave to form a heat dissipation groove that directly opens to the outside, effectively increasing the contact area between the heat dissipation boss and the external air, strengthening the heat dissipation effect. Heat dissipation fins are evenly arranged in the heat dissipation groove, further increasing the contact area with the external air and also strengthening the heat dissipation effect.

Detailed implementation manners

[0042] To make the objectives, technical solutions and advantages of the implementation of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0043] As Figures 1 to 8 shown, an embodiment of the present invention provides an optoelectronic conversion device box for the trackside. The box includes two housings 1. The two housings 1 are detachably connected, and a waterproof rubber ring 2 is provided at the connection. The detachable connection parts are all located outside the waterproof rubber ring 2. An installation cavity is formed between the two housings 1. The housing 1 is also provided with a heat dissipation structure for natural heat dissipation.

[0044] In the above technical solution, after the two shells 1 are fixed together by detachable connection, they form a box body for the trackside optoelectronic conversion device. The use of detachable connection facilitates assembly and subsequent equipment maintenance. A waterproof rubber ring 2 is provided around the entire circumference of the connection between the two shells 1. Setting the detachable connection part outside the waterproof rubber ring 2 can better form a closed installation cavity between the two shells 1, which is beneficial to enhancing the waterproof effect of the box body. The box body of this solution realizes natural heat dissipation of the box body through the heat dissipation structure on the shell 1, without the need for an additional fan for heat dissipation, ensuring the integrity of the box body structure and also being beneficial to further enhancing the waterproof performance of the box body. The above technical solution adopts a modular optoelectronic conversion device box body, which reduces the volume and weight of the box body. At the same time, the box body also has waterproof and heat dissipation functions, enabling the optoelectronic conversion device to be an independent outdoor device, which is light and low-cost, and can be installed and relocated at any time, thus better meeting the actual application requirements. Specifically in implementation, the overall shape of the box body in this embodiment is a cuboid.

[0045] The optoelectronic conversion device box body in the embodiment of the present invention adopts a miniaturized and integrated box form, which changes the traditional device form of the optoelectronic conversion device. The trackside optoelectronic conversion device of the present invention can be used outdoors independently without a separate cabinet, saving manpower and material resources for equipment installation and reducing costs.

[0046] As a preferred technical solution, as Figure 4 shown, the detachable connection is a threaded connection. A plurality of inwardly protruding connection platforms 3 are provided around the shell 1. A connection hole 4 for threaded connection is provided in the middle of the connection platform 3. Each connection hole 4 is located outside the waterproof rubber ring 2. In this embodiment, the two shells 1 are detachably connected by a plurality of connection bolts. The connection holes 4 for threaded connection include through holes and threaded holes. Among them, a through hole adapted to the connection bolt is provided on the connection platform 3 of one shell 1, and a threaded hole adapted to the connection bolt is provided on the connection platform 3 of the other shell 1. The waterproof rubber ring 2 is installed on the inner edge of the connection platform 3, that is, each connection hole 4 is located outside the waterproof rubber ring 2. In this way, the connection hole 4 itself does not penetrate the inside of the shell 1, which can better form a closed installation cavity between the two shells 1, and thus can better achieve sealing and waterproofing. Specifically in implementation, installation grooves are formed at the parts of the shell 1 corresponding to the connection holes 4, which is convenient for installing the connection bolts.

[0047] As a preferred technical solution, as Figure 2 、 Figure 3 and Figure 7As shown, the cross-section of the waterproof rubber ring 2 is U-shaped. Two protruding first sealing parts 5 are arranged on one side of the waterproof rubber ring 2, and a second sealing part 6 is arranged on the other side. Two first sealing grooves adapted to the first sealing parts 5 are arranged on one housing 1, and a second sealing groove adapted to the second sealing part 6 is arranged on the other housing 1. In this embodiment, a sealing boss is formed between the two first sealing grooves, and a sealing groove 7 adapted to the sealing boss is formed between the two first sealing parts 5. During assembly, the two first sealing parts 5 on one side of the waterproof rubber ring 2 are respectively snapped into the two first sealing grooves, and the sealing boss is just snapped into the sealing groove 7. The second sealing part 6 on the other side of the waterproof rubber ring 2 is snapped into the second sealing groove. In this solution, the sealing between the two housings 1 adopts a waterproof rubber ring 2 with a U-shaped cross-section. This structural design effectively increases the sealing surface, can achieve better sealing, and is beneficial to enhancing the waterproof performance of the box body. Specifically, installation inclined surfaces are arranged on both sides of the sealing boss. Correspondingly, a sealing inclined surface 8 adapted to the installation inclined surface is arranged on one side of the first sealing part 5. The installation inclined surface can make the first sealing groove wider outside and narrower inside, which is convenient for the first sealing part 5 to be better snapped into the first sealing groove during assembly. During assembly, after squeezing the waterproof rubber ring 2, the sealing of the gap can be well achieved. The waterproof rubber ring 2 of this embodiment is preferably integrally formed of silicone rubber to ensure the sealing effect.

[0048] As a preferred technical solution, as Figure 1 and Figure 4 shown, a bracket 9 is detachably connected to the bottom of the box body, and all plugs or sockets for external connection on the box body are arranged at the bottom of the box body. In this embodiment, the plugs or sockets are used to connect the inside and outside of the box body. In this solution, all plugs or sockets are arranged at the bottom of the box body instead of on the side or top of the box body, which can effectively prevent water from seeping into the box body from the plugs or sockets and enhance the waterproof effect. The bracket 9 of this embodiment adopts a U-shaped bracket 9 and there are two of them. An installation platform 10 is arranged at each end of the U-shaped bracket 9. The installation platforms 10 at both ends of the U-shaped bracket 9 are fixedly connected to the bottom of the box body by threaded connection. By arranging the bracket 9, the whole box body can stand better on the ground. The bracket 9 has a certain support height, which can make the box body have a certain distance from the ground. This not only facilitates the installation of plugs or sockets for external connection at the bottom of the box body, but also can prevent the box body from being affected by the accumulated water on the ground and enhance the waterproof effect of the box body. The plugs and sockets mentioned above are all prior arts and will not be specifically described here.

[0049] Adopting the above structural design (including that the connection holes 4 are all outside the waterproof rubber ring 2, the U-shaped structure of the waterproof rubber ring 2, and the bottom bracket 9, etc.) enables the photoelectric conversion device box body of the present invention to have an IP67 protection level and good waterproof effect, so as to better cope with the outdoor environment.

[0050] As a preferred technical solution, as Figures 4 to 6As shown in the figure, a circuit board 11 is fixedly installed inside the box body. The heat dissipation structure includes a heat dissipation boss 12 arranged inside the housing 1. The surface of the heat dissipation boss 12 is closely attached to the heat generating components on the circuit board 11. The heat dissipation structure further includes a heat dissipation groove 13 arranged on the outer side surface of the housing 1. The heat dissipation groove 13 is located outside the heat dissipation boss 12, and heat dissipation fins 14 are arranged in the heat dissipation groove 13. In this embodiment, a plurality of electronic components are installed on the circuit board 11 according to actual requirements. The above-mentioned heat generating components refer to those components with relatively large heat generation among these electronic components. For the heat generating components on the circuit board 11, in this embodiment, corresponding heat dissipation bosses 12 are specifically arranged on the housing 1, and the surface of the heat dissipation boss 12 is closely attached to the surface of the heat generating components. In this way, the heat generated by the heat generating components will be transferred to the entire housing 1 through heat conduction, so that the heat generating components can effectively dissipate heat. In order to better achieve heat dissipation, the outer side of the heat dissipation boss 12 (that is, the side of the heat dissipation boss 12 away from the middle of the box body) is recessed to form a heat dissipation groove 13 that directly opens to the outside, effectively increasing the contact area between the heat dissipation boss 12 and the external air, strengthening the heat dissipation effect. Heat dissipation fins 14 are also evenly arranged in the heat dissipation groove 13, further increasing the contact area with the external air and also strengthening the heat dissipation effect. During specific implementation, heat dissipation grooves 13 and heat dissipation fins 14 can be arranged only on the outside of some larger heat dissipation bosses 12 (that is, those with larger diameters). For smaller heat dissipation bosses 12 with smaller diameters, heat dissipation grooves 13 and heat dissipation fins 14 may not be arranged. By installing a matching circuit board 11 in the box body of this embodiment, various control functions can be realized.

[0051] In some embodiments, a plurality of heat dissipation protrusions 15 in an array form are arranged on the surface of the heat dissipation boss 12. The surface of the heat dissipation protrusions 15 is closely attached to the surface of the heat generating components. Heat dissipation grooves 16 are formed between the heat dissipation protrusions 15. In this embodiment, by arranging heat dissipation protrusions 15 on the surface of the heat dissipation boss 12 and forming heat dissipation grooves 16, it is not only convenient for heat conduction and dissipation through direct contact, but also can accelerate heat dissipation through the heat dissipation grooves 16, enabling the heat generating components on the circuit board 11 to have a better heat dissipation effect. Preferably, the heat dissipation protrusions 15 are square and arranged in an array, and a plurality of heat dissipation grooves 16 that intersect horizontally and vertically are formed, as Figure 8 shown.

[0052] As a preferred technical solution, as Figure 4 and Figure 5As shown, there are two circuit boards 11. A plurality of connecting posts 17 are provided on the inner sides of the two housings 1, and the circuit boards 11 are fixedly arranged on the connecting posts 17. There is a heat dissipation cavity 18 between the two circuit boards 11. In this embodiment, the circuit board 11 is fixedly connected to the connecting posts 17 on the inner side of the housing 1 by means of threaded connection. The heights of the respective connecting posts 17 on one housing 1 are the same, so that the circuit board 11 fixed to the connecting posts 17 is parallel to the outer surface of the housing 1. The height of the connecting posts 17 determines the distance between the circuit board 11 and the outer surface of the housing 1. The heat dissipation cavity 18 between the two circuit boards 11 can facilitate heat dissipation and ensure the heat dissipation effect. In this embodiment, two circuit boards 11 are provided inside the box body (i.e., a dual-circuit board 11 design is adopted). This design has the following advantages: First, it can carry and install more electronic components. In this way, when installing the same number of components, the distance between the components can be made larger, and the heat dissipation effect is better. Second, when the distance between the outer surfaces of the two housings 1 is certain, the circuit board 11 inside the box body can be closer to the outer surface of the housing 1, which is convenient for the heat dissipation bosses 12 on the housing 1 to better contact the heat-generating components on the circuit board 11 for heat dissipation.

[0053] As a preferred technical solution, as Figure 1 and Figure 6 shown, the heat dissipation structure further includes heat dissipation fins 19. A plurality of the heat dissipation fins 19 are uniformly arranged on the outer surface of the housing 1. In this embodiment, the heat dissipation fins 19 are in a long strip shape. Three groups of longitudinally uniformly arranged long strip-shaped heat dissipation fins 19 are sequentially arranged on the outer surface of the housing 1 from top to bottom. The heat dissipation fins 19 protrude outwards, effectively increasing the contact area between the housing 1 and the air, and further increasing the heat dissipation efficiency.

[0054] As a preferred technical solution, the housing 1 is integrally formed of aluminum alloy. In this embodiment, the housing 1 is integrally formed of 6063 aluminum alloy, which is convenient for processing and has sufficient structural strength. 6063 aluminum alloy also has good thermal conductivity. The metal housing 1 made of this material can achieve good heat dissipation through heat exchange with the outside world, and can further enhance the heat dissipation effect of the heat dissipation structure (including heat dissipation bosses 12, heat dissipation grooves 13, heat dissipation fins 19, etc.). The metal housing 1 in this embodiment has good thermal conductivity and can achieve real-time heat dissipation outdoors, improving the heat dissipation effect.

[0055] Adopting the above structural design (including heat dissipation bosses 12, heat dissipation grooves 13, heat dissipation fins 14, heat dissipation fins 19, and the housing 1 being integrally formed of 6063 aluminum alloy, etc.) enables the photoelectric conversion device box body of the present invention to achieve natural heat dissipation of the box body well, without the need for additional fan heat dissipation, and has a good heat dissipation effect, so as to better cope with the outdoor environment.

[0056] As a preferred technical solution, as Figure 1 and Figure 4As shown in the figure, a rotary storage handle 20 is provided at the top of each of the two housings 1, and a storage groove 21 adapted to the rotary storage handle 20 is provided on the housing 1. In this embodiment, when the handle is not needed, the rotary storage handle 20 can be stored in the storage groove 21 on the housing 1, which does not occupy space and is aesthetically pleasing. When the handle is needed, the rotary storage handle 20 can be directly rotated to unfold the handle, which is convenient for taking the entire box body. Specifically, the rotary storage handle 20 is integrally formed by a sheet metal forming process, and the handle itself has a low cost and a light weight. Flanges 22 are provided on both sides of the rotary storage handle 20, which can improve the comfort and safety of taking the handle. In this embodiment, both ends of the rotary storage handle 20 are fastened to the housing 1 by screws, which can make the rotary storage handle 20 have better load-bearing performance. The rotary storage handle 20 in this embodiment is a hidden handle, which is convenient for hand-held taking.

[0057] Based on the same inventive concept, an embodiment of the present invention further provides a trackside optoelectronic conversion device, including a device body, and further including the optoelectronic conversion device box body as described above, and the device body is disposed in the optoelectronic conversion device box body. In this embodiment, the trackside optoelectronic conversion device adopts the foregoing optoelectronic conversion device box body, which can enable the trackside optoelectronic conversion device to have waterproof and heat dissipation functions, making the optoelectronic conversion device a separate outdoor device, which is light and low in cost, and can be installed and relocated at any time, thus better meeting the actual application requirements. The device body includes an optical modem, the foregoing circuit board 11, and electronic components disposed on the circuit board 11, etc. The device body belongs to the prior art and will not be elaborated herein. The specific structure of the optoelectronic conversion device box body has been described in detail in the embodiment related to the box body, and will not be elaborated herein.

[0058] As Figure 1 shown in the figure, according to the actual application requirements of the trackside optoelectronic conversion device, indicator lights 23 for reflecting the device state can be provided on the side and top of the optoelectronic conversion device box body, and a lamp position groove 24 for installing the indicator lights 23 is reserved on the top of the box body. In this embodiment, hanging mounting holes 25 are also provided on the side of the box body, which can facilitate the wall mounting of the device box body.

[0059] In the above embodiments, the descriptions of the various embodiments have their own emphases. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0060] The parts not involved in the above embodiments are the same as or can be implemented by the prior art, and will not be further described herein.
