[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 9 As shown, an embodiment of the present invention provides a locking rod structure 1, which includes a rod body 10 and multiple limit seats 20. The rod body 10 is installed on the door body 2 through the multiple limit seats 20. The multiple limit seats 20 are distributed at intervals along the axial direction of the rod body 10 and cooperate with the rod body 10. There are two or more installation connection points 401 between at least one limit seat 20 and the door body 2.

[0037] In this embodiment, the number of installation connection points 401 between the locking rod structure 1 and the door body 2 is increased, and multi-point connection, linear connection or surface connection between the locking rod structure 1 and the door body 2 is realized, wherein the linear connection can be understood as being composed of multiple or even countless installation connection points 401, and the surface connection can be understood as being composed of multiple or even countless connection lines, that is, the surface connection can also be understood as being composed of countless installation connection points 401. Compared with the prior art where the locking rod structure 1 and the door body 2 have fewer and more dispersed connection points, this embodiment can further reduce the force at the position of each installation connection point 401 to avoid local deformation. In addition, when the door body 2 is subjected to force, the force can be dispersed by more connection points 401, thereby increasing the service life of the locking rod structure 1.

[0038] It can be understood that the connection method between the limit seat 20 and the rod body 10 is the existing technology. For the sake of ease of understanding, the limit seat 20 includes a limit section and a transition section that are connected to each other. The limit section has a limit groove or a limit hole for limiting the installation of the rod body 10. The transition section and the rod body 10 are connected to the door body 2 through multiple spaced fasteners (bolts 51, rivet screws 52, etc., which can be adjusted according to actual conditions). The position of any fastener connecting the transition section and the door body 2 forms an installation connection point 401.

[0039] Among them, the limiting seat 20 includes at least one mounting seat 21 and at least one reinforcement seat 22, one end of the mounting seat 21 is connected to the door body, and the other end is used to connect to the box body where the door body 2 is located; the reinforcement seat 22 is distributed along the axial direction of the rod body 10 and cooperates with the rod body 10, and there is an installation connection point 401 between the mounting seat 21 and the door body 2 and between the reinforcement seat 22 and the door body 2.

[0040] In this embodiment, the locking rod structure 1 also includes a support seat 30 for connecting the limit seat 20 and the door body 2. At least a portion of the limit seat 20 is fixedly mounted on the support seat 30. There are two or more mounting connection points 401 between the support seat 30 and the door body 2, or there is a linear connection or surface connection between the support seat 30 and the door body 2. This arrangement is conducive to further improving the connection strength and deformation resistance between the locking rod structure 1 and the door body. It is understandable that the linear connection between the support seat 30 and the door body 2 is composed of countless linearly arranged mounting connection points 401, and the surface connection between the support seat 30 and the door body 2 is composed of countless planarly arranged mounting connection points 401.

[0041] In such Figures 1 to 3 In the embodiment 1 shown, the locking rod structure 1 does not include the support seat 30, the mounting seat 21 is connected to the door body 2 and has at least one mounting connection point 401, and the reinforcing seat 22 is connected to the door body 2 and has at least one mounting connection point 401. At this time, there is only a connection point between the reinforcing seat 22 and the door body 2, that is, the setting of the reinforcing seat 22 can increase the number of connection points between the locking rod structure 1 and the door body 2 relative to only setting the mounting seat 21. When the weight of the door body 2 remains unchanged, the force applied to each connection point can be reduced, thereby further reducing the deformation probability of the door body 2 at the connection point. At the same time, there are connection points between the mounting seat 21 and the door body 2 and the box body where the door body 2 is located, that is, the mounting seat 21 plays the role of strengthening the transition strength between the locking rod structure 1 and the door body 2, and strengthening the transition strength between the locking rod structure 1 and the box body where the door body 2 is located.

[0042] In such Figure 4 and Figure 5 The second embodiment shown, Figure 6 The third embodiment shown and Figures 7 to 9 In the fourth embodiment shown, the locking rod structure 1 includes a support seat 30, which is connected to the door body 2 and has at least one installation connection point 401. At least one installation seat 21 and at least one reinforcement seat 22 are both arranged on the support seat 30. The reinforcement seat 22 is connected to the door body 2, and the installation seat 21 is also connected to the door body 2. This arrangement can improve the structural strength of the locking rod structure 1 itself, and avoid problems such as damage between the limit seat 20 and the support seat 30 due to uneven force.

[0043] It can be understood that the setting of the support seat 30 can be adjusted according to actual conditions. For example, in another embodiment not shown in the figure, part of the limit seat 20 is directly installed on the door body 2, and the other part of the limit seat 20 is installed on the door body 2 through the support seat 30. The installation connection points 401 are distributed between the part of the limit seat 20 and the door body 2 and between the support seat 30 and the door body 2.

[0044] The number of mounting seats 21 and reinforcement seats 22, as well as their axial extension lengths along the rod body 10, can be adjusted based on actual requirements. For example, if the force concentration is concentrated at a certain location and not at other locations, only one mounting seat 21 can be installed at that location, with its axial extension length along the rod body 10 extending to both ends of the concentrated force location. The same applies to the reinforcement seats 22.

[0045] Furthermore, in this embodiment, there are two or more mounting blocks 21, and at least one reinforcement block 22 is provided between any two adjacent mounting blocks 21. This arrangement further increases the number of connection points between the locking rod structure 1 and the door body 2. In this embodiment, there are six mounting blocks 21, spaced apart along the length of the rod body 10, with two reinforcement blocks 22 provided between any two adjacent mounting blocks 21.

[0046] It can be understood that the arrangement of multiple (two or more) mounting seats 21 and multiple (two or more) reinforcement seats 22 can be adjusted according to actual conditions. In actual applications, any mounting seat 21 can be provided with at least one reinforcement seat 22 on both sides along the axial direction of the rod body 10. For example, one or more reinforcement seats 22 can be provided between one mounting seat 21 and the next adjacent mounting seat 21. The specific number of settings can be determined according to actual needs, and examples are not given here one by one.

[0047] Specifically, multiple installation connection points 401 are distributed on both sides of the rod body 10. This arrangement ensures the reliability and stability of the installation of the lock rod structure 1 and the door body 2, avoids the situation where the multiple installation connection points 401 are distributed on the same side of the rod body 10, which is prone to concentrated force (concentrated on the same side of the rod body 10) and causes damage to the lock rod structure 1 or the door body 2, and ensures the stability of the connection between the lock rod structure 1 and the door body 2.

[0048] Preferably, the plurality of mounting connection points 401 are evenly distributed on both sides of the axis of the rod body 10. Figures 1 to 3In the embodiment 1 shown, in this embodiment, two installation connection points 401 are formed between any limit seat 20 and the door body 2, and the two installation connection points 401 between any limit seat 20 and the door body 2 are symmetrically distributed on both sides of the axis of the rod body 10 to ensure the reliability and stability of the installation of each limit seat 20 and the door body 2, and at the same time are conducive to improving the force dispersion effect when the door body 2 is in use.

[0049] It is understandable that the installation point between the limit seat 20 and the door body 2 or the support seat 30 can be adjusted according to actual conditions, and part of the limit seat 20 can form an installation point with the door body 2 or the support seat 30.

[0050] like Figure 4 and Figure 5 The second embodiment shown and Figures 7 to 9 In the fourth embodiment shown, the locking rod structure 1 includes a single support base 30, multiple mounting connection points 401 are formed between the same support base 30 and the door body 2, and multiple position limiting bases 20 are fixedly mounted on the same support base 30. This arrangement allows multiple position limiting bases 20 to be connected to the door body 2 through a single support base 30, which facilitates the processing and installation of the support base 30.

[0051] Among them, there are two or more installation connection points 401 between any support seat 30 and the door body 2. Specifically, the surface of the support seat 30 used to install the limit seat 20 is the installation surface 301, and the surface of the support seat 30 used to install with the door body 2 is the connection surface 302. There are two or more installation connection points 401 between the connection surface 302 and the door body 2. Any support seat 30 has at least one connection surface 302 and at least one installation surface 301.

[0052] exist Figure 4 and Figure 5 In the second embodiment shown, the support seat 30 is a flat plate, which has a connecting surface 302 and a mounting surface 301 on opposite sides in the thickness direction. The connecting surface 302 of the support seat 30 is in contact with the transfer surface 201 and there are multiple mounting connection points 401 between the two. Furthermore, the support seat 30 and the door body 2 can be connected by line, such as welding the edge of the support seat 30 and the door body 2; or by surface connection, such as welding the connecting surface 302 of the support seat 30 and the door body 2 to further reduce the stress on the connection point.

[0053] Furthermore, the projections of the axis of the rod body 10 on the connecting surface 302 and the mounting surface 301 are both located in the middle area thereof, thereby avoiding uneven force between the parts of the door body 2 located on both sides of the rod body 10 and reducing the probability of deformation of the door body 2.

[0054] exist Figure 7 and Figure 8 In the fourth embodiment shown, the support seat 30 is a bridge plate, the length direction of the support seat 30 extends along the axial direction of the rod body 10, and the cross section of the support seat 30 on a plane perpendicular to the axial direction of the rod body 10 is U-shaped or Ω-shaped. Figure 8 As shown, the support seat 30 has a connecting surface 302 on opposite sides of the rod body 10. Both connecting surfaces 302 of the support seat 30 mate with the transition surface 201. Multiple mounting connection points 401 are located between any of the connecting surfaces 302 and the transition surface 201 of the door body 2. The top surface of the support seat 30, facing away from the door body 2, serves as the mounting surface 301. The position limiting seat 20 is fixed to the mounting surface 301 by bolts 51. In this embodiment, the two connecting surfaces 302 are symmetrically distributed on either side of the axis of the rod body 10, with the projection of the axis of the rod body 10 on the mounting surface 301 located in the middle area of ​​the mounting surface 301. This arrangement facilitates the operator to process the support seat 30 according to actual needs, ensuring a smooth transition while achieving lightweighting and other effects. Furthermore, the single plate configuration allows for the connection of different numbers of position limiting seats 20 with different distributions on the door body 2, thereby improving the applicability of the support seat 30.

[0055] On the other hand, there can be multiple support seats 30, and multiple support seats 30 are spaced apart along the length direction of the door body 2 (the axial direction of the rod body 10), and / or multiple support seats 30 are spaced apart along the width direction of the door body 2 (the direction perpendicular to the axial direction of the rod body 10 on the plane where the door body 2 is located). Figure 6 In the third embodiment shown, there are two support seats 30, and the projections of the two support seats 30 on the transfer surface 201 are symmetrically distributed on both sides of the center line of the projection of the rod body 10 on the transfer surface 201 (that is, spaced apart along the width direction of the door body 2), and the two limit seats 20 are distributed on multiple support seats 30, and any support seat 30 is connected to the door body 2 by a line connection or a surface connection. In this way, the multi-point connection mode between the limit seat 20 and the door body 2 is changed to a line connection or a surface connection, which increases the number of connection points and further reduces the force on the connection points, thereby reducing the probability of deformation of the door body 2. At the same time, it is also beneficial for the operator to set the support seat 30 at the position where reinforcement is required according to the actual situation, which is beneficial for targeted reinforcement and further avoids deformation of the door body 2.

[0056] It is understandable that the plurality of support seats 30 can be alternately distributed left and right along the axial direction of the rod body 10 , and their arrangement can be adjusted according to actual needs to reinforce the position, which will not be exemplified here one by one.

[0057] It should be noted that for Figures 4 to 9The support seat 30 in the illustrated embodiment has the number of connection surfaces 302 and the number of mounting surfaces 301 which can be adaptively adjusted according to actual conditions. The support seat 30 can be a plate with an H-shaped cross-section, that is, it has two connection surfaces 302 and two mounting surfaces 301, and the limit seat 20 is connected to the two connection surfaces 302 respectively.

[0058] Specifically, when the locking rod structure 1 does not include the support seat 30 and the limiting seat 20 is directly connected to the door body 2, the limiting seat 20 and the door body 2 are connected by at least one of welding, riveting, clamping, and pressing to form at least one installation connection point 401. When the locking rod structure 1 includes the support seat 30 and the limiting seat 20 is connected to the door body 2 via the support seat 30, the support seat 30 and the door body 2 are connected by at least one of welding, riveting, clamping, and pressing to form at least one installation connection point 401. The support seat 30 and the limiting seat 20 are connected by at least one of welding, riveting, clamping, and pressing. This arrangement can ensure the reliability and stability of the connection between the locking rod structure 1 and the door body 2.

[0059] In such Figures 1 to 3 In the illustrated embodiment 1, the mounting seat 21 is connected to the door body 2 via bolts 51 to form four mounting connection points 401, which are distributed in a rectangular pattern on either side of the rod body 10. The reinforcing seat 22 is connected to the door body 2 via bolts 51 to form two mounting connection points 401, which are symmetrically distributed on either side of the rod body 10. The line connecting the multiple mounting connection points 401 on the same side of the rod body 10 is parallel to the axis of the rod body 10. This arrangement, taking one of the mounting seats 21 as an example, transforms the original single-point fixation into a four-point fixation. Under the same tensile force, the single-point pressure is reduced to 1 / 4-1 / 2 of the original, and the deformation resistance is 2-4 times the original. The same applies to the location of the reinforcing seat 22. Combined with the distribution of multiple mounting seats 21 and multiple reinforcing seats 22, the force distribution effect and deformation resistance of the lock rod structure 1 and the door body 2 are further improved.

[0060] In such Figures 4 to 9 In the embodiment shown, the mounting base 21 and the support base 30 are connected by four bolts 51, which are distributed in a rectangular shape on both sides of the rod body 10. The reinforcing base 22 and the door body 2 are connected by two bolts 51, which are symmetrically distributed on both sides of the rod body 10. The connecting line of the multiple bolts 51 on the same side of the rod body 10 is parallel to the axis of the rod body 10. This arrangement is conducive to improving the tensile strength of the lock rod structure 1 itself, and improving the reliability and stability of the lock rod structure 1. Figure 6 In the third embodiment shown, a plurality of bolt members 51 symmetrically distributed on both sides of the rod body 10 are respectively formed between the limiting seat 20 and the two supporting seats 30 (mounting surfaces 301 ).

[0061] On the other hand, in Figure 6 The third embodiment shown and Figures 7 to 9 In the fourth embodiment shown, the two connecting surfaces 302 of the support seat 30 are welded to the transfer surface 201. It can be understood that it is equivalent to connecting the multiple installation connection points 401 located on the same side of the rod body 10 in the first embodiment together and forming two linear planes on both sides of the rod body 10 (equivalent to having countless installation connection points 401 on the plane). Compared with the multi-point transfer in the first embodiment, the transfer area of ​​this transfer method is larger, which further improves the pressure-bearing capacity and anti-deformation ability of the door body 2 per unit area.

[0062] like Figure 4 and Figure 5 In the second embodiment shown, in this embodiment, the connecting surface 302 of the support seat 30 is welded to the transfer surface 201. It can be understood that it is equivalent to extending the two linear planes in the third and fourth embodiments in the radial direction of the rod body 10 and connecting them into the same plane (the plane is equivalent to having countless linear planes, and each linear plane has countless installation connection points 401). The transfer area of ​​this transfer method will be further increased. At this time, the pressure per unit area of ​​the door body 2 will be lower, so that deformation of the door body can be more effectively and thoroughly prevented.

[0063] It should be noted that in Figures 1 to 3 In the embodiment shown, a plurality of pressure riveting screws 52 are prefabricated on the door body 2; Figures 4 to 9 In the illustrated embodiment, the support base 30 is a linear plate or a rectangular plate, on which a plurality of rivet screws 52 are prefabricated, and the rivet depth does not extend to the door body 2 .

[0064] Another embodiment of the present invention provides a power electronic device box, which includes a door body 2, a box body and the above-mentioned locking rod structure 1. The locking rod structure 1 is arranged on the door body 2 and connected to the box body through a limit seat 20. The box body is provided with power electronic equipment or a battery.

[0065] This embodiment reduces the damage to the door body 2 caused by the tension of the locking rod by adding the installation connection points 401 to the locking rod structure 1. The layout of multiple installation connection points 401 can be adjusted according to the actual door body size, weight, and door opening frequency (multi-point arrangement, linear arrangement, or plane arrangement). It can be applied to more product requirements, reduce the pressure on the door body 2, reduce the deformation of the door body 2, and improve the product life of the power electronic equipment box.

[0066] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0068] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0069] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures.
