[0041] The features and exemplary embodiments of various aspects of the present application will be described in detail below. To make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0042] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.

[0043] In the field of intelligent driving, intelligent driving algorithms require a large amount of data to train models. Existing intelligent driving domain controllers are basically patch-type memories, that is, the memories are directly soldered to the circuit board. However, the memory capacity of the patch-type memory itself is usually low, and the data capacity that can be stored is easily limited.

[0044] In addition, data usually needs to be transferred to the server. The data transfer of the patch-type memory depends on the cloud, and the transmission of the cloud is restricted by the working environment of the vehicle. If the working environment is a closed environment such as a port or a factory, and the network signal quality of the working environment is poor, the data cannot be uploaded and the model cannot be trained.

[0045] Therefore, there is an urgent need for a storage means with a large capacity and not relying on cloud transmission. Consumer-grade storage units such as solid-state drives can transfer data locally and no longer rely on the cloud. Among them, consumer-grade usually refers to products designed, marketed and sold for consumers, families or for home use, consumption or enjoyment. And the solid-state drive itself can have a large capacity, which can solve the problem of algorithm model training in the development of intelligent driving algorithms to a certain extent. However, because it is a consumer-grade product, its dust-proof performance and anti-seismic performance at the interface are both poor. The vehicle will generate vibrations and impacts during driving, which easily leads to the disconnection of the connection at the interface and the problem that data cannot be stored.

[0046] In view of this, in a first aspect, please refer to Figures 1 to 3 , an embodiment of the present application provides a fixing device for fixing a storage unit 30 and a plugging unit 40. The fixing device includes a housing 10 and a fixing structure 20, and the housing 10 is provided with an accommodating cavity.

[0047] The fixing structure 20 is located in the accommodating cavity. The fixing structure 20 includes a fixing plate 21 and a bending member 22. The fixing plate 21 includes a first part 211 and a second part 212 arranged side by side in the first direction X. The first part 211 is provided with a first limiting hole H1, and the first limiting hole H1 penetrates through the first part 211 in the thickness direction Z of the fixing plate 21. The plugging unit 40 passes through the first limiting hole H1 and is connected to the first part 211. The bending member 22 is arranged on at least one side of the second part 212 in the second direction Y and is connected to the bending member 22. Wherein, the first direction X, the second direction Y, and the thickness direction Z intersect pairwise.

[0048] The fixing device is a device for fixing the storage unit 30 and the plugging unit 40. The storage unit 30 is a component with a certain capacity for storing data. For example, the storage unit 30 may include a solid-state drive. The plugging unit 40 can be electrically connected to the storage unit 30, and an output port may be provided on the plugging unit 40 for electrical connection with other components to meet the need for data transfer and transmission in the storage unit 30. For example, the plugging unit 40 may include an adapter board.

[0049] The fixing device at least includes a housing 10 and a fixing structure 20. The housing 10 is a hollow structure and is provided with an accommodating cavity. The storage unit 30 and the plugging unit 40 can be arranged in the accommodating cavity. The housing 10 can protect the storage unit 30 and the plugging unit 40, reduce the influence of external vibration and impact on the storage unit 30 and the plugging unit 40, and can also reduce the intrusion of dust and other impurities into the storage unit 30 and the plugging unit 40, playing a certain dust-proof role.

[0050] The fixing structure 20 is arranged in the accommodating cavity. The fixing structure 20 is fixedly connected to the housing 10, and both the storage unit 30 and the plugging unit 40 are fixed to the fixing structure 20. The fixing structure 20 can play a role in fixing the relative positions between the storage unit 30 and the plugging unit 40.

[0051] The fixing structure 20 at least includes a fixing plate 21 and a bending member 22. The fixing plate 21 is in a plate-like structure and is the main part of the fixing structure 20. The fixing plate 21 includes a first part 211 and a second part 212 arranged side by side in the first direction X. Both the first part 211 and the second part 212 are also in plate-like structures. Wherein, the first part 211 and the second part 212 can be connected to each other, or the first part 211 and the second part 212 can also be spaced apart in the first direction X. And according to different actual needs, the first part 211 and the second part 212 can be made of the same material and be an integral structure, or the two can also be made of different materials and be independently prepared, and then connected and fixed by welding or other means. Figure 3The case where the first part 211 and the second part 212 are of an integral structure is shown, and the junction of the first part 211 and the second part 212 is schematically shown by a dotted line.

[0052] The first part 211 is provided with a first limiting hole H1. The first limiting hole H1 penetrates through the first part 211 along the thickness direction Z. Part of the structure in the plugging unit 40 can pass through the first limiting hole H1, and the first limiting hole H1 can play a role in limiting the plugging unit 40. Optionally, the contour shape of the first limiting hole H1 can be adapted to the outer contour of the plugging unit 40. Further, the plugging unit 40 can also be connected to the first part 211 by means such as welding and bolt connection. In this way, the plugging unit 40 can be fixed to the first part 211, and by virtue of the limitation of the plugging unit 40 by the first limiting hole H1, the risk of relative movement of the plugging unit 40 relative to the first part 211 caused by factors such as vibration or impact can be reduced, and the reliability of the relative position between the plugging unit 40 and the first part 211 can be improved.

[0053] The bending member 22 is arranged on at least one side of the second part 212 along the second direction Y. The first direction X, the second direction Y, and the thickness direction Z are three different directions. Optionally, the first direction X, the second direction Y, and the thickness direction Z are perpendicular to each other in pairs. The number of the bending members 22 can be one, or can also be multiple. When the number of the bending members 22 is multiple, the multiple bending members 22 can be located on the same side of the second part 212 in the second direction Y, or the multiple bending members 22 can also be separately arranged on different sides of the second part 212 in the second direction Y.

[0054] It should be noted that Figure 3 only shows the direction of the straight line parallel to the thickness direction Z in one case, and it does not constitute a limitation on the orientation of the thickness direction Z. In other words, in combination with Figure 3 it can be said that the embodiment of the present application does not limit the thickness direction Z to be the direction from bottom to top or from top to bottom. The thickness direction Z itself does not have a specific orientation, and the same is true for the first direction X and the second direction Y. The embodiment of the present application does not make any restrictions on this.

[0055] The bending member 22 is bent and connected to the fixing plate 21, and the bending member 22 can protrude and extend relative to the fixing plate 21 along the thickness direction Z. Among them, there can be various connection methods between the bending member 22 and the fixing plate 21. For example, both of them can include the same material and be integrally formed, and then the bending member 22 is formed by bending. Or both of them can also include different materials and be independently formed, and then are connected and fixed by means such as welding.

[0056] The storage unit 30 is connected to the bent member 22, and the bent member 22 is connected to the fixing plate 21, so that the relative fixation between the storage unit 30 and the fixing plate 21 can be achieved. And the bent member 22 is located at at least one side of the storage unit 30 along the second direction Y, so as to limit the position of the storage unit 30 in the second direction Y. At the same time, the fixing plate 21 is located at one side of the storage unit 30 in the thickness direction Z, so as to limit the position of the storage unit 30 in the thickness direction Z, and improve the position reliability of the storage unit 30.

[0057] In summary, in the embodiment of the present application, the fixing plate 21 includes a first part 211 and a second part 212 arranged side by side. The plugging unit 40 is fixed at the first part 211, and the storage unit 30 is fixed at the second part 212, so as to reduce the risk of physical interference between the plugging unit 40 and the storage unit 30. Further, a first limiting hole H1 is provided on the first part 211, and the first limiting hole H1 can limit the position of the plugging unit 40. The bent member 22 is connected to the second part 212. In addition to the function of fixing the storage unit 30, the bent member 22 can also limit the position of the storage unit 30 together with the fixing plate 21. Furthermore, it helps to improve the reliability of the relative position between the plugging unit 40 and the storage unit 30, reduce the risk of relative displacement between the plugging unit 40 and the storage unit 30 due to factors such as vibration and impact, and improve the reliability of data transmission.

[0058] It should be noted that the fixing device provided in the embodiment of the present application can be applied not only in the field of intelligent driving to realize the relative fixation of the storage unit 30 and the plugging unit 40, but also in other technical fields. In other words, as long as the storage unit 30 and the plugging unit 40 need to be relatively fixed and there are certain requirements for the reliability of the relative position between the two, the fixing device provided in the embodiment of the present application can be adopted.

[0059] In some embodiments, please refer to Figures 1 to 4 , the housing 10 includes a first housing 11. The first housing 11 includes a bottom plate 111 and a first side portion 112 bent and connected to the periphery of the bottom plate 111. The fixing plate 21 is connected to the first side portion 112 and is spaced apart from the bottom plate 111 in the thickness direction Z.

[0060] The first housing 11 is one of the components for forming the outer housing 10. The first housing 11 at least includes a bottom plate 111 and a first side portion 112. The bottom plate 111 has a plate-like structure and is located on one side of the fixing plate 21 in the thickness direction Z. The bottom plate 111 is used to provide the bottom surface of the accommodation cavity. The first side portion 112 is bent and connected to the periphery of the bottom plate 111. The first side portion 112 is used to provide the side surface of the accommodation cavity. Exemplarily, the bottom plate 111 can be a rectangular plate and has four sides. Different structures in the first side portion 112 are respectively connected to different sides of the bottom plate 111, and adjacent structures are connected to each other. Among them, according to different actual needs, the first side portion 112 can be a plate-like structure, or the first side portion 112 can also be in a regular or irregular block structure.

[0061] In the embodiment of the present application, the fixing plate 21 is not connected to the bottom plate 111, but is connected to the first side portion 112. In this way, there can be a certain gap space between the fixing plate 21 and the bottom plate 111 in the thickness direction Z, and this gap space can be used to accommodate part of the structure of the plug-in unit 40. Further, the storage unit 30 is located on the side of the fixing plate 21 facing away from the bottom plate 111. This design enables part of the structure in the plug-in unit 40 and the storage unit 30 to be located on different sides of the fixing plate 21, thereby further reducing the risk of structural interference between the plug-in unit 40 and the storage unit 30 and improving the reliability of the relative positions between the two.

[0062] It should be noted that there can be various connection methods between the fixing plate 21 and the first side portion 112. For example, at least part of the structure in the first side portion 112 is located on one side of the fixing plate 21 along the first direction X and is fixed to the fixing plate 21 by welding or threaded connection. Or, at least part of the structure in the first side portion 112 is located on one side of the fixing plate 21 along the second direction Y and is fixed to the fixing plate 21 by welding or threaded connection.

[0063] In some embodiments, the first side portion 112 includes two first sub-portions 112a respectively arranged on both sides of the bottom plate 111 along the second direction Y. The first sub-portion 112a has opposite first ends D1 and second ends D2 in the thickness direction Z. The first end D1 is connected to the bottom plate 111. The first sub-portion 112a includes a first groove A1 formed by inward depression from the first end D1. The first groove A1 communicates with the accommodation cavity. Among them, the groove bottom surface of the first groove A1 is spaced from the bottom plate 111 in the thickness direction Z, and the fixing plate 21 is connected to the groove bottom surface of the first groove A1.

[0064] The first sub - part 112a is a partial structure in the first side - part 112. Two first sub - parts 112a are oppositely arranged in the second direction Y and are respectively arranged on both sides of the bottom plate 111. Optionally, the first sub - part 112a protrudes relative to the bottom plate 111 in the thickness direction Z, and the two first sub - parts 112a are symmetrically arranged on both sides of the bottom plate 111.

[0065] The first sub - part 112a has opposite first end D1 and second end D2 in the thickness direction Z. The first end D1 and the second end D2 are two ends of the first sub - part 112a. The first end D1 is connected to the bottom plate 111. The first sub - part 112a and the bottom plate 111 can be an integral structure and are bent at the first end D1 to form the first sub - part 112a. Or the first sub - part 112a and the bottom plate 111 can also be a split structure, and the two are connected and fixed by means such as welding.

[0066] The second end D2 is the end of the first sub - part 112a relatively far from the bottom plate 111. The first groove A1 is recessed from the first end D1 in the direction close to the bottom plate 111. Among them, the first groove A1 is arranged to communicate with the accommodation cavity in the second direction Y, that is, the first groove A1 not only recesses from the first end D1 in the direction close to the bottom plate 111, but also recesses inward from the surface of the first sub - part 112a facing the accommodation cavity.

[0067] The bottom surface of the first groove A1 is spaced from the bottom plate 111 in the thickness direction Z. The "bottom surface of the first groove A1" mentioned in the embodiments of the present application refers to the surface used to form the first groove A1 in the thickness direction Z. Further, in the embodiments of the present application, by placing a partial structure of the fixing plate 21 on the bottom surface of the first groove A1 and connecting the fixing plate 21 to the bottom surface of the first groove A1, while meeting the need for relative fixation between the fixing plate 21 and the housing 10, the fixing plate 21 can also be spaced from the bottom plate 111, so as to meet the installation need of the plug - in unit 40, which has strong practicability.

[0068] It should be noted that the fixing plate 21 can have various structural forms, and the embodiments of the present application do not limit the specific structure of the fixing plate 21. Optionally, the fixing plate 21 can include a body part and a protruding part. The first part 211 and the second part 212 together constitute the body part, and the protruding part can protrude relative to the body part in the second direction Y, and the protruding part can be embedded into the first groove A1 and connected and fixed to the bottom surface of the first groove A1. Further, the number of the first grooves A1 can be one or can also include multiple. For example, one first sub - part 112a can be provided with two first grooves A1. On this basis, the fixing plate 21 can be provided with four protruding parts, and the four protruding parts are respectively arranged corresponding to the four first grooves A1 on the two first sub - parts 112a.

[0069] In some embodiments, such as Figures 1 to 4 shown, the fixing device further includes a heat dissipation member 50. The heat dissipation member 50 is disposed on a side of the second portion 212 facing away from the storage unit 30 and is connected to the second portion 212. The second portion 212 is provided with a communication hole H2. The communication hole H2 penetrates through the second portion 212 along the thickness direction Z, and a projection of the communication hole H2 in the thickness direction Z overlaps with projections of both the storage unit 30 and the heat dissipation member 50 in the thickness direction Z.

[0070] During the operation of the storage unit 30, a large amount of heat is generated in the storage unit 30. If the heat cannot be dissipated in time, it is likely to affect the normal use of the storage unit 30 and even cause problems such as fire. To address this issue, in the embodiments of the present application, a heat dissipation member 50 is additionally provided in the fixing device. The heat dissipation member 50 is a component capable of dissipating heat in time. Optionally, the heat dissipation member 50 may include a fan structure.

[0071] In the embodiments of the present application, the heat dissipation member 50 is used to adjust the temperature of the storage unit 30, and both the heat dissipation member 50 and the storage unit 30 are fixed to the second portion 212. To reduce the risk of structural interference between the heat dissipation member 50 and the storage unit 30, the heat dissipation member 50 and the storage unit 30 are arranged on both sides of the second portion 212 along the thickness direction Z, so as to minimize the distance between the two while meeting the layout requirements of the heat dissipation member 50 and the storage unit 30, thereby improving the heat dissipation performance.

[0072] Further, to better realize the heat dissipation function of the heat dissipation member 50 for the storage unit 30, the embodiments of the present application also provide a communication hole H2 on the second portion 212, and a projection of the communication hole H2 in the thickness direction Z is set to overlap with projections of both the storage unit 30 and the heat dissipation member 50 in the thickness direction Z, so that the communication hole H2 can achieve communication between the area where the heat dissipation member 50 is located and the area where the storage unit 30 is located. In this way, the heat dissipation member 50 can better absorb the heat from the storage unit 30 and dissipate the heat in time, thereby further improving the use reliability and service life of the storage unit 30.

[0073] It should be noted that according to different actual needs, the fixing device may optionally include the heat dissipation member 50, or the fixing device may also optionally not include the heat dissipation member 50. In this case, the heat dissipation member 50, the plugging unit 40, and the storage unit 30 need to be installed in the fixing device together.

[0074] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5, a ventilation opening H3 is formed in the bottom plate 111. The first housing 11 further includes a dust-proof portion 113 protruding from the side of the bottom plate 111 facing the fixing plate 21. The dust-proof portion 113 encloses a channel structure H4 communicating with the ventilation opening H3, and at least a part of the heat dissipation member 50 is located in the channel structure H4. Wherein, in the thickness direction Z, the fixing plate 21 is in contact with the dust-proof portion 113.

[0075] The ventilation opening H3 penetrates the bottom plate 111 in the thickness direction Z and is used to communicate the accommodation cavity and the external environment. Exemplarily, the projection of the ventilation opening H3 in the thickness direction Z overlaps with the projection of the heat dissipation member 50 in the thickness direction Z, that is, the positions of the ventilation opening H3 and the heat dissipation member 50 are correspondingly arranged, so that the heat dissipation member 50 can transfer the heat generated by the storage unit 30 to the external environment, improving the overall heat exchange effect.

[0076] The dust-proof portion 113 is connected to the bottom plate 111 and is located in the accommodation cavity. The presence of the dust-proof portion 113 can reduce the probability of dust and other impurities invading the accommodation cavity, improving the reliability of the device. The dust-proof portion 113 can enclose a channel structure H4 communicating with the ventilation opening H3. The radial contour shape of the channel structure H4 can be the same as that of the ventilation opening H3, or there can be differences between the two. The embodiments of the present application do not limit this. Optionally, the projections of the channel structure H4 and the ventilation opening H3 in the thickness direction Z coincide with each other and form a rectangular structure.

[0077] In the embodiments of the present application, by arranging the heat dissipation member 50 in the channel structure H4, the heat dissipation member 50 can realize heat exchange with the external environment through the channel structure H4 and the ventilation opening H3, thereby improving the heat exchange effect. And the presence of the dust-proof portion 113 can not only play a dust-proof role, but also be in contact with the fixing plate 21 in the thickness direction Z. In this way, the dust-proof portion 113 can provide a certain support for the fixing plate 21, which is more conducive to the spaced arrangement between the fixing plate 21 and the bottom plate 111. Further, compared with the scheme where the bottom plate 111 is directly in contact with the fixing plate 21, the contact area between the dust-proof portion 113 and the fixing plate 21 is smaller. In this way, when the housing 10 is impacted or vibrates, the smaller contact area will bring a smaller vibration impact. Therefore, it helps to reduce the vibration or impact on the fixing plate 21 and the storage unit 30, the plug-in unit 40 and the heat dissipation member 50 arranged on the fixing plate 21, improving the reliability of use.

[0078] It should be noted that although the heat dissipation member 50 is located within the channel structure H4, the peripheral structure of the heat dissipation member 50 may be in contact with the dust-proof portion 113, or the peripheral structure of the heat dissipation member 50 may be spaced apart from the dust-proof portion 113. The embodiments of the present application do not limit this. Further, when the peripheral structure of the heat dissipation member 50 is in contact with the dust-proof portion 113, the heat dissipation member 50 may also be fixedly connected to the dust-proof portion 113 by means such as welding to improve the position reliability of the heat dissipation member 50. Or the heat dissipation member 50 may not be connected to the dust-proof portion 113 to facilitate subsequent replacement and repair of the heat dissipation member 50.

[0079] In some embodiments, as Figures 2 to 4 shown, the fixing device further includes a connecting member 60. The connecting member 60 is used to connect the plugging unit 40 and the fixing plate 21 and is located on the side of the fixing plate 21 facing the bottom plate 111. The bottom plate 111 has a first surface M1 facing the fixing plate 21 and a recessed structure A3 formed by inward depression of the first surface M1. A part of the connecting member 60 is located within the recessed structure A3.

[0080] The connecting member 60 is a component for realizing connection and fixation between different components. The connecting member 60 may have various forms. For example, the connecting member 60 may include a bolt structure 61. And in addition to the connecting member 60 for connecting the plugging unit 40 and the fixing plate 21 being provided to include the bolt structure 61, as Figure 2 shown, the connection between other structures within the fixing device may also be through the bolt structure 61. The embodiments of the present application do not limit this.

[0081] The connecting member 60 is located on the side of the fixing plate 21 facing the bottom plate 111. In combination with the attached drawings, the connecting member 60 can gradually approach the fixing plate 21 and the plugging unit 40 from below the fixing plate 21 to realize relative fixation between the fixing plate 21 and the plugging unit 40. After the fixing plate 21 and the plugging unit 40 are connected, some structures in the connecting member 60 may protrude relative to the plugging unit 40. If the bottom plate 111 is a flat surface at the corresponding position of the plugging unit 40, during the process of assembling the fixing plate 21 into the housing 10 and after the assembly is completed, the bottom plate 111 may come into contact interference with the connecting member 60, affecting the structural reliability of the housing 10 and the connection reliability between the fixing plate 21 and the plugging unit 40.

[0082] In view of this, the embodiments of the present application adjust the structure of the bottom plate 111 so that the first surface M1 on the bottom plate 111 can form a recessed structure A3 by inward depression. The recessed structure A3 can accommodate some structures in the connecting member 60, thereby reducing the risk of contact interference between the bottom plate 111 and the connecting member 60 and improving the reliability of the housing 10 and the connection reliability between the fixing plate 21 and the plugging unit 40.

[0083] Regarding the quantity and size of the concave structure A3, the embodiments of the present application do not impose any limitations. Exemplarily, the quantity of the concave structure A3 may be the same as the quantity of the connecting member 60, and the size and shape of the concave structure A3 may be adapted to the connecting member 60. In this way, the cooperation between the concave structure A3 and the connecting member 60 can also play a certain positioning role, improving the reliability of the relative position between the bottom plate 111 and the fixing plate 21.

[0084] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 , the housing 10 includes a first housing 11 and a second housing 12 that are connected to each other. The first housing 11 includes a bottom plate 111, a first side portion 112 that is bent and connected to the peripheral side of the bottom plate 111, and a boss structure 114 that protrudes from the side of the first side portion 112 facing away from the accommodation cavity. The second housing 12 includes an end cover 121. In the thickness direction Z, the surface of the boss structure 114 facing away from the bottom plate 111 is flush with the surface of the first side portion 112 facing away from the bottom plate 111, and the end cover 121 contacts and connects to the boss structure 114.

[0085] The housing 10 at least includes two structural parts, the first housing 11 and the second housing 12. The first housing 11 and the second housing 12 are covered and connected to each other and jointly define an accommodation cavity. Among them, there can be various connection methods between the first housing 11 and the second housing 12. For example, the first housing 11 and the second housing 12 can be connected and fixed by means such as welding and threaded connection.

[0086] In addition to the bottom plate 111 and the first side portion 112, the first housing 11 further includes a boss structure 114. The boss structure 114 is a partial structure on the first housing 11 for realizing the connection and fixation with the second housing 12. The boss structure 114 is connected to the first side portion 112 and protrudes from the outer surface of the first side portion 112 relative to the first side portion 112.

[0087] The second housing 12 at least includes an end cover 121. The end cover 121 can be in a plate-like structure and is spaced from the bottom plate 111 in the thickness direction Z. Among them, the distance between the end cover 121 and the bottom plate 111 in the thickness direction Z determines the size of the accommodation cavity in the thickness direction Z.

[0088] In an embodiment of the present application, in order to meet the connection requirement between the first housing 11 and the second housing 12, a boss structure 114 is provided on the first housing 11, and the boss structure 114 is used for connecting and fixing with the end cover 121. Among them, in order to improve the connection reliability between the first housing 11 and the second housing 12, the surface of the boss structure 114 facing away from the bottom plate 111 is flush with the surface of the first side portion 112 facing away from the bottom plate 111. In this way, the surface of the boss structure 114 and the surface of the first side portion 112 facing away from the bottom plate 111 can jointly form a flat surface, and the end cover 121 can be supported by both the boss structure 114 and the first side portion 112, improving the support strength of the first housing 11 for the end cover 121. At the same time, it helps to reduce the connection difficulty between the end cover 121 and the boss structure 114 and improve the connection strength between the two.

[0089] Regarding the shape, size and specific quantity of the boss structure 114, the embodiment of the present application does not make any restrictions. Optionally, the number of the boss structures 114 is multiple, and the multiple boss structures 114 are respectively arranged at different positions of the first side portion 112, and the multiple boss structures 114 are respectively connected and fixed with different positions of the end cover 121, so as to improve the connection strength between the two.

[0090] In some embodiments, please refer to Figure 2 、 Figure 4 、 Figure 6 and Figure 7 , the second housing 12 includes a second side portion 122, and the second side portion 122 is bent and connected to the end cover 121 and extends in a direction close to the bottom plate 111. The first side portion 112 includes a second sub-portion 112b arranged on at least one side of the bottom plate 111 along the first direction X. The second sub-portion 112b has opposite third end D3 and fourth end D4 in the thickness direction Z. The third end D3 is connected to the bottom plate 111. The second sub-portion 112b includes a second groove A2 formed by inward depression from the fourth end D4. The second groove A2 communicates with the accommodation cavity and the external environment. At least a part of the second side portion 122 is located in the second groove A2 and is spaced from the groove bottom surface of the second groove A2.

[0091] The first side portion 112 includes two first sub-portions 112a located on both sides of the bottom plate 111 in the second direction Y, and a second sub-portion 112b arranged on at least one side of the bottom plate 111 along the first direction X. The two ends of the second sub-portion 112b in the second direction Y are respectively connected to the two first sub-portions 112a. Among them, the number of the first sub-portions 112a is two, and according to different actual needs, the number of the second sub-portions 112b can be one, or the number of the second sub-portions 112b can also be two.

[0092] The second sub - part 112b has opposite third end D3 and fourth end D4 in the thickness direction Z. The third end D3 is connected to the bottom plate 111, and the fourth end D4 is the end of the second sub - part 112b away from the bottom plate 111. The second groove A2 is recessed from the fourth end D4 towards the direction close to the bottom plate 111, and the second groove A2 can communicate the accommodation cavity with the external environment. That is, in addition to being recessed in the thickness direction Z, the second groove A2 also runs through the first sub - part 112a along the first direction X. Wherein, the groove bottom surface of the second groove A2 refers to the corresponding surface of the second groove A2 in the thickness direction Z.

[0093] The second housing 12 includes a second side part 122. The second side part 122 is bent and connected to the end cover 121, and there can be various connection methods between the two. For example, the two can be of an integral structure and formed by bending processes respectively, or the two can be independently manufactured and formed, and connected and fixed by welding or other means.

[0094] The second side part 122 is correspondingly arranged with the second groove A2. During the assembly process of the first housing 11 and the second housing 12, the second side part 122 can gradually penetrate into the interior of the second groove A2 along the thickness direction Z. However, since the dimension of the second side part 122 in the thickness direction Z is smaller than the dimension of the second groove A2 in the thickness direction Z, after the first housing 11 and the second housing 12 are installed, the second side part 122 and the groove bottom surface of the second groove A2 are still spaced apart in the thickness direction Z.

[0095] In the embodiment of the present application, the gap space formed between the second side part 122 and the groove bottom surface of the second groove A2 can realize the communication between the accommodation cavity and the external environment. Further optionally, the output end C on the plug - in unit 40 can be partially located in this gap space to meet the need for data transfer between the storage unit 30 and other external structures. At the same time, under this design, the second side part 122 and the second sub - part 112b can jointly play a limiting role on the output end C of the plug - in unit 40, thereby improving the position reliability of the plug - in unit 40.

[0096] In some embodiments, please refer to Figure 2 、 Figure 4 and Figure 8 , the second housing 12 includes a first positioning part W1 provided on the end cover 121, the first housing 11 includes a second positioning part W2 provided on the boss structure 114, and the first positioning part W1 and the second positioning part W2 are in plug - in fit. And / or, the fixing structure 20 includes a third positioning part provided on the first part 211, the plug - in unit 40 is configured to include a fourth positioning part, and the third positioning part and the fourth positioning part are in plug - in fit.

[0097] The plug-in fit between the first positioning portion W1 and the second positioning portion W2 is used to achieve relative positioning between the first housing 11 and the second housing 12 to improve the reliability of the relative position between the two. The first positioning portion W1 and the second positioning portion W2 can have a variety of structural modes. For example, the first positioning portion W1 can be a pin structure provided on the end cover 121, and the second positioning portion W2 is a pin hole structure provided on the boss structure 114 and matched with the pin structure. Alternatively, the first positioning portion W1 can be a pin hole mechanism provided on the end cover 121, and the second positioning portion W2 is a pin structure provided on the boss structure 114.

[0098] Further optionally, the boss structure 114 is provided with a pin hole structure and a threaded hole structure located next to the pin hole structure, and the end cover 121 is provided with a pin shaft structure and a threaded hole structure located next to the pin shaft structure. Through the mutual cooperation between the pin shaft structure and the pin hole structure, the end cover 121 and the boss structure 114 can be in contact with each other, so that the two threaded hole structures on the boss structure 114 and the end cover 121 can be aligned with each other, and then the bolt structure 61 can be screwed into the two threaded hole structures to achieve a fixed connection between the first shell 11 and the second shell 12.

[0099] Similarly, the plug-in cooperation between the third positioning part and the fourth positioning part is used to realize the relative positioning between the fixing plate 21 and the plug-in unit 40, so as to improve the reliability of the relative position between the two. The third positioning part and the fourth positioning part can have a variety of structural modes, for example, the third positioning part can be a pin structure provided on the first part 211, and the fourth positioning part can be a pin hole structure provided on the plug-in unit 40. Alternatively, the third positioning part can be a pin hole structure provided on the first part 211, and the fourth positioning part can be a pin structure provided on the plug-in unit 40.

[0100] It should be noted that, depending on actual needs, only the first positioning portion W1 and the second positioning portion W2 may be provided to achieve the relative positioning between the first shell 11 and the second shell 12, or only the third positioning portion and the fourth positioning portion may be provided to achieve the relative positioning between the fixed plate 21 and the plug-in unit 40, or the first positioning portion W1, the second positioning portion W2, the third positioning portion and the fourth positioning portion may be provided at the same time to simultaneously satisfy the relative positioning between the first shell 11 and the second shell 12 and the relative positioning between the fixed plate 21 and the plug-in unit 40.

[0101] Second, as Figure 1 and Figure 2As shown in the figure, an embodiment of the present application provides a storage device, which includes a fixing device, a storage unit 30 and a plugging unit 40 in any of the foregoing embodiments.
