[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3, a data acquisition box provided by the present invention will now be described. A data acquisition box includes a first housing 1, a second housing 2, and a locking assembly. Among them, the second housing 2 is inserted and cooperated with the first housing 1. The second housing 2 has an installation surface 21 and an outer surface 22 arranged opposite to each other, and a connector 3 for connecting electronic components 7 is inserted on the installation surface 21. The locking assembly is arranged on the installation surface 21 for locking the connector 3. The first housing 1 and the second housing 2 have a first insertion form and a second insertion form. In the first insertion form, the first housing 1 and the second housing 2 form a first box structure, and the installation surface 21 is located inside the first box structure. In the second insertion form, the first housing 1 and the second housing 2 form a second box structure, and the installation surface 21 is located outside the second box structure.

[0033] Specifically, please refer to Figure 3 and Figure 4 , the first housing 1 includes two side plates 12, a top plate 13 fixed between the two side plates 12, and a box door 14 hinged to any one of the side plates 12. The two side plates 12 are arranged opposite to each other and parallel to each other. The top plate 13 is located at the top of the side plates 12 and is perpendicular to the side plates 12. The second housing 2 includes a back plate 25 and a bottom plate 26, and the installation surface 21 and the outer surface 22 are arranged on the back plate 25. The bottom plate 26 is fixedly arranged at the bottom of the back plate 25 and is perpendicular to the back plate 25. A wire hole for the wire harness to pass through is provided on the bottom plate 26. Whether it is the first insertion form or the second insertion form, the back plate 25 is inserted between the two side plates 12 along the length direction of the side plates 12, and the bottom plate 26 is parallel to the top plate 13.

[0034] In the first insertion form, the first housing 1 and the second housing 2 form a closed first box structure. Like a traditional data acquisition box, it can create a relatively stable working environment for the internally integrated electronic components 7, ensuring the stable operation of data acquisition, transmission, and preliminary processing functions.

[0035] When the staff needs to install the electronic components 7, they can pre-fix the electronic components 7 and the connector 3, without the need to operate in a narrow box like the traditional installation method. Then, switch the first housing 1 and the second housing 2 to the second insertion form, so that the installation surface 21 is completely exposed to the outside. The staff can easily install the connector 3 in the appropriate position and freely use tools to connect the wire harnesses between the various electronic components 7. The hand movements are no longer restricted by space, the operation range is greatly broadened, and the installation efficiency is significantly improved.

[0036] In some embodiments, please refer to Figure 5 and Figure 6The locking assembly includes two locking parts 41 and two connecting rods 42. The two locking parts 41 are slidably arranged in the second shell 2 and are suitable for being plugged into the connecting member 3. The sliding direction of the locking parts 41 is perpendicular to the insertion direction of the connecting member 3. The two connecting rods 42 correspond to the locking parts 41 one by one. One end of each connecting rod 42 is fixed to the corresponding locking part 41, and the other end passes through another locking part 41 and the second shell 2 in sequence and extends outward to form a linkage block 43. The two connecting rods 42 extend from both sides of the second shell 2 respectively, and the two linkage blocks 43 are respectively located on both sides of the second shell 2.

[0037] Specifically, the locking assembly is disposed on the back plate 25. By moving the linkage block 43, the connecting rod 42 can be driven to move, and the connecting rod 42 can drive the locking portion 41 to move. When the connector 3 is plugged into the back plate 25, by moving the two linkage blocks 43, the locking portion 41 can be driven to plug into the connector 3, thereby limiting the connector 3 and ensuring that the connector 3 will not be detached from the back plate 25.

[0038] In some embodiments, see Figure 7 and Figure 8 Two limiting portions 11 are fixedly arranged on the first housing 1 along the insertion direction of the second housing 2, and the two limiting portions 11 are respectively located on both sides of the first housing 1. In the first plug-in form, the two limiting portions 11 respectively abut against the outer sides of the two linkage blocks 43 to limit the two linkage blocks 43, so that the two locking portions 41 are always connected to the connector 3. In the second plug-in form, the two limiting portions 11 avoid the two linkage blocks 43 respectively.

[0039] Specifically, the two limiting portions 11 are respectively arranged on the inner walls of the two side panels 12 and extend along the insertion direction of the back panel 25. In the first plug-in form, the back panel 25 is plugged between the two side panels 12, and the two limiting portions 11 are respectively against the outer sides of the two linkage blocks 43, thereby limiting the linkage blocks 43, making the linkage blocks 43 unable to move, thereby ensuring that the locking portion 41 is continuously and firmly connected to the connector 3. In the second plug-in form, the back panel 25 is plugged between the two side panels 12, at which time the limiting portion 11 avoids the linkage blocks 43, ensuring that the linkage blocks 43 can move normally, thereby unlocking the old connector 3 and installing the new connector 3.

[0040] In some embodiments, see Figure 9 , Figure 10 and Figure 11 The first housing 1 and the second housing 2 are plugged with fixing pins 51. There are two fixing pins 51, which are respectively located on both sides of the first housing 1. The insertion ends of the two fixing pins 51 are fixedly provided with first wedge blocks 61.

[0041] In the first plugging state, when the two fixing pins 51 are plugged into the second housing 2, the two first wedge blocks 61 respectively avoid the two linkage blocks 43. In the second plugging state, when the two fixing pins 51 are plugged into the second housing 2, the two first wedge blocks 61 respectively abut against the inner sides of the two linkage blocks 43 and push the two linkage blocks 43 to move in opposite directions, so that the two locking portions 41 are separated from the connecting member 3.

[0042] In the first plug-in form, when the fixing pin 51 connects the first shell 1 and the second shell 2, the first wedge block 61 can avoid the linkage block 43, so as not to push the linkage block 43, thereby ensuring that the connection between the locking portion 41 and the connecting member 3 is not affected.

[0043] In the second plug-in form, the staff needs to install or remove the connector 3. At this time, the fixing pin 51 is used to connect the first shell 1 and the second shell 2. The two first wedge blocks 61 respectively abut against the inner sides of the two linkage blocks 43, thereby pushing the two linkage blocks 43 to move away from each other, so that the two locking parts 41 are away from each other, thereby realizing the separation of the locking part 41 and the connector 3, making it convenient for the staff to remove the old connector 3 and install the new connector 3.

[0044] In some embodiments, see Figure 4 , Figure 10 and Figure 11 Two first fixing sleeves 52 and two second fixing sleeves 53 are fixedly arranged on the first shell 1. The two first fixing sleeves 52 are respectively arranged on the two side plates 12, and the two second fixing sleeves 53 are respectively arranged on the two side plates 12. The first fixing sleeve 52 and the second fixing sleeve 53 are arranged along the insertion direction of the second shell 2, and the first fixing sleeve 52 is farther away from the top plate 13 than the second fixing sleeve 53. The first slot 23 and the second slot 24 are both opened on both sides of the second shell 2. The number of the first slot 23 and the second slot 24 is two. The first slot 23 and the second slot 24 are both arranged on the back plate 25. The first slot 23 is closer to the bottom plate 26 than the second slot 24.

[0045] In the first plugging mode, the fixing pin 51 is inserted in the first fixing sleeve 52 and the first slot 23, and the first wedge block 61 avoids the linkage block 43. In the second plugging mode, the fixing pin 51 is inserted in the second fixing sleeve 53 and the second slot 24, and the first wedge block 61 abuts the linkage block 43.

[0046] Specifically, the first fixing sleeve 52 and the second fixing sleeve 53 provide clear and accurate insertion position guidance for the fixing pin 51 in the first insertion form and the second insertion form. In the first insertion form, the fixing pin 51 should be inserted into the first fixing sleeve 52 and the first slot 23, which ensures the tight connection between the first housing 1 and the second housing 2, and also ensures that the first wedge-shaped block 61 is in a position to avoid the linkage block 43, thereby maintaining the locking state of the locking portion 41 and the connecting member 3. In the second insertion form, the fixing pin 51 should be inserted into the second fixing sleeve 53 and the second slot 24 to ensure that the first wedge-shaped block 61 can abut against the linkage block 43 and push the linkage block 43 to move, driving the locking portion 41 to move, thereby facilitating the installation of a new connecting member 3 and the removal of an old connecting member 3.

[0047] In some embodiments, referring to Figure 9 , a positioning pin 54 is inserted into the first fixing sleeve 52 and the second fixing sleeve 53, and the insertion direction of the positioning pin 54 is perpendicular to the insertion direction of the fixing pin 51. A moving magnet 55 is fixedly arranged on the positioning pin 54, and a fixed magnet 56 is fixedly arranged on the first fixing sleeve 52 or the second fixing sleeve 53. A through hole 511 suitable for the positioning pin 54 to pass through is formed in the fixing pin 51. When the fixing pin 51 is inserted into either the first fixing sleeve 52 or the second fixing sleeve 53, the positioning pin 54 can be inserted into the through hole 511, and the moving magnet 55 and the fixed magnet 56 are attracted to each other.

[0048] To prevent the fixing pin 51 from loosening from the first fixing sleeve 52 or the second fixing sleeve 53, when the fixing pin 51 is inserted into either the first fixing sleeve 52 or the second fixing sleeve 53, the positioning pin 54 is inserted into the first fixing sleeve 52 and the second fixing sleeve 53, so that the positioning pin 54 can be inserted into the through hole 511 at the same time, thereby fixing the position of the fixing pin 51. At the same time, the adsorption effect of the moving magnet 55 and the fixed magnet 56 can also ensure the firmness of the positioning pin 54.

[0049] In some embodiments, referring to Figure 12 , the connecting member 3 includes a connecting plate 31 and a connecting column 32. Among them, the connecting plate 31 is used to fix the electronic component 7. The connecting column 32 is fixedly arranged on the connecting plate 31, and a groove 321 suitable for the locking portion 41 to be inserted into is formed on the circumferential surface. The mounting surface 21 is evenly provided with jacks 211, and the connecting column 32 is suitable for being inserted into any one of the jacks 211.

[0050] The connecting plate 31 provides a stable fixing platform for the electronic component 7. The staff can first install the electronic component 7 on the connecting plate 31 by means of screw fixation, and then insert the connecting column 32 into the jack 211 on the mounting surface 21. When the connecting column 32 is inserted in place, the locking part 41 can move to the insertion groove 321 to lock the connecting column 32. This method of first fixing the electronic component 7 on the connecting plate 31 and then installing the connecting plate 31 on the mounting surface 21 greatly improves the installation efficiency of the electronic component 7 and reduces the difficulty of directly installing the electronic component 7 in a narrow space.

[0051] At the same time, the uniformly distributed jacks 211 on the mounting surface 21 allow the connecting column 32 to be inserted into any jack 211 according to actual needs, providing great flexibility for the layout of the electronic components on the mounting surface 21. This enables the staff to flexibly adjust the layout of the electronic component 7 according to factors such as the circuit connection relationship, heat dissipation requirements, and space utilization efficiency among the electronic components 7.

[0052] In some embodiments, please refer to Figure 5 and Figure 6 , the locking part 41 includes a plurality of locking plates 411 arranged in sequence along the axial direction of the connecting rod 42. Each locking plate 411 in the two locking parts 41 corresponds to each other and is symmetric to form a clamping structure. A plurality of notches 4111 are formed on the opposite sides of each corresponding locking plate 411. When each pair of corresponding locking plates 411 are joined together, a clearance hole is formed between the opposite notches 4111, and the clearance holes correspond to the jacks 211 one by one. A convex block 412 is fixedly arranged on the inner wall of the notch 4111. When the connecting column 32 is inserted into the jack 211, the two corresponding locking plates 411 clamp the connecting column 32 so that the connecting column 32 extends into the clearance hole, and the convex block 412 is connected to the groove 321.

[0053] When connecting the connecting member 3, inserting the connecting column 32 into the jack 211 can also make the connecting column 32 extend into the notch 4111 on the locking plate 411 at the same time. At this time, just push the two linkage blocks 43 to make the corresponding locking plates 411 approach and join together, then the clamping of the connecting column 32 can be achieved, so that the convex block 412 and the groove 321 are inserted into each other, thereby locking the connecting column 32 and preventing the connecting column 32 from being pulled out of the jack 211.

[0054] In some embodiments, please refer to Figure 6 , the locking assembly further includes two springs 44. The two springs 44 are respectively sleeved on the two connecting rods 42, and both ends of each spring 44 are fixed to the locking part 41 and the second housing 2 respectively. The spring 44 is used to push the two locking parts 41 to move towards each other so that the two locking parts 41 are connected to the connecting member 3.

[0055] When changing from the second plugging form to the first plugging form, the second housing 2 needs to be pulled out from the first housing 1. At this time, the two locking portions 41 can move towards each other under the action of the elastic force of the spring 44, so as to be connected to the connecting member 3, ensuring the stability of the connecting member 3 on the second housing 2 and preventing the connecting member 3 from becoming loose when the second housing 2 is moved.

[0056] In some embodiments, please refer to Figure 13 , second wedge blocks 62 are fixedly arranged on both sides of the first housing 1. In the second plugging form, the two second wedge blocks 62 respectively abut against the inner sides of the two linkage blocks 43, so that the two locking portions 41 are separated from the connecting member 3.

[0057] During actual use, when connecting the first housing 1 and the second housing 2 in the second plugging form, the second wedge block 62 can also play a role in pushing the linkage block 43, so as to cooperate with the first wedge block 61, ensuring the movement effect of the linkage block 43 and avoiding the situation where the linkage block 43 is not pushed.

[0058] All in all, compared with the prior art, for the data acquisition box provided by the present invention, when a staff member needs to install the electronic component 7, the electronic component 7 and the connecting member 3 can be fixed in advance, without the need to operate in a narrow box body like the traditional installation method. When installing the connecting member 3, the first housing 1 and the second housing 2 are connected in the second plugging form, so that the installation surface 21 is located outside the second box structure and is exposed. The staff member can operate in an open space environment, with more flexible hand movements, and can easily plug and unplug the connecting member 3, connect the circuits between the various electronic components 7, etc., greatly improving the convenience of installation and maintenance and reducing the operation time and difficulty. After the installation is completed, the first housing 1 and the second housing 2 are connected in the first plugging form. At this time, it is the normal use form of the data acquisition box, and the electronic component 7 is located inside the first box structure, so that the first housing 1 and the second housing 2 protect the electronic component 7.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
