[0036] The exemplary embodiments will be described in detail below with reference to the drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The embodiments described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0037] In the prior art, the distribution box has a plurality of first threaded holes, and the bottom plate of the battery pack has a plurality of second threaded holes, and a plurality of screws are sequentially connected through the first threaded holes and the second threaded holes to mount the distribution box on the bottom plate of the battery pack. However, the screw connection is a rigid connection, and the vibration and impact are not basically dissipated on the screw, so when the above-mentioned bottom plate vibrates, the vibration on the bottom plate will be completely transmitted to the distribution box through the screw, affecting the stability and reliability of the distribution box.

[0038] Based on this, the embodiment of the present application provides a supporting leg structure, which comprises a supporting piece and at least one damping piece. The supporting piece is used to be connected with a to-be-supported piece, and the supporting piece is provided with at least one first mounting groove. The damping piece is rotatably connected in the first mounting groove, and the damping piece at least partially extends out of the first mounting groove to be rotatably connected with the supporting piece. By arranging the damping piece, when the supporting piece vibrates, the damping piece can absorb and slow down part of the impact and vibration, so as to reduce the impact and vibration transmitted to the mounting piece and the to-be-supported piece, thereby improving the stability and reliability of the to-be-supported piece. By arranging the damping piece to be rotatably connected with the inner wall of the first mounting groove and rotatably connected with the supporting piece, the damping piece can rotate relative to the mounting piece and the supporting piece, thereby changing the inclination direction and angle of the damping piece relative to the vertical direction, so that the damping piece can buffer the vibration and impact in multiple directions, thereby improving the damping effect of the damping piece. By arranging the first mounting groove on the mounting piece, the first mounting groove accommodates part of the damping piece, so as to limit the damping piece through the first mounting groove, thereby preventing the damping piece from rotating at too large an angle relative to the mounting piece and affecting the stability of the damping piece.

[0039] The embodiment of the present application will be described below with reference to the drawings.

[0040] Referring to Figure 1 and Figure 2 , the embodiment of the present application provides a supporting leg structure 100 for connecting a to-be-supported piece with a supporting piece supporting the to-be-supported piece, which comprises a mounting piece 110 and at least one damping piece 120. The mounting piece 110 is used to be connected with the to-be-supported piece, and the mounting piece 110 is provided with at least one first mounting groove 112. The damping piece 120 is rotatably connected with the inner wall of the first mounting groove 112, and the damping piece 120 at least partially extends out of the first mounting groove 112 to be rotatably connected with the supporting piece. The damping piece 120 is used to slow down the vibration and impact on the supporting piece.

[0041] For example, the to-be-supported piece is located above the supporting piece. The first mounting groove 112 is a rectangular groove, and the first mounting groove 112 is provided with an opening. The damping piece 120 extends out of the first mounting groove 112 through the opening of the first mounting groove 112. The opening of the first mounting groove 112 faces downward, i.e., the opening faces the supporting piece, so as to facilitate the rotatable connection between the damping piece 120 and the supporting piece. Further, the groove bottom of the first mounting groove 112 is opposite to the opening of the first mounting groove 112, and the first connecting part 122 is rotatably connected with the groove bottom of the first mounting groove 112, so that the connection between the damping piece 120 and the first mounting groove 112 is more stable.

[0042] Specifically, one end of the damping member 120 is located in the first mounting slot 112 and rotationally connected with the inner wall of the first mounting slot 112, so that the damping member 120 can rotate relative to the mounting member 110. The other end of the damping member 120 extends out of the first mounting slot 112 and is rotationally connected with the support member, so that the damping member 120 can rotate relative to the support member. By rotating the damping member 120 relative to the mounting member 110 and the support member, the inclination direction and angle of the damping member 120 relative to the vertical direction are adjusted, so that the damping member 120 can slow down the vibration and impact in different directions on the support member.

[0043] It can be understood that when the damping member 120 is installed, the included angle between the damping member 120 and the vertical direction can be adjusted to adjust the damping effect of the damping member 120 in the vertical direction and the horizontal direction, so that the damping effect of the damping member 120 in the required damping direction in actual use is better.

[0044] In some embodiments, the damping member 120 is located in the first mounting slot 112, the damping member 120 is inclined relative to the bottom and at least two side walls of the first mounting slot 112 and is not perpendicular to the bottom and the at least two side walls, and the bottom of the first mounting slot 112 is parallel to the horizontal plane, so that the damping effect of the damping member 120 can be decomposed into three directions, thereby improving the damping effect of the damping member 120.

[0045] In specific implementation, the impact and vibration on the support member are transmitted to the support structure 100, and by arranging the damping member 120, part of the impact and vibration is absorbed, so as to reduce the impact and vibration transmitted by the support structure 100 to the to-be-supported member, thereby protecting the to-be-supported member and ensuring the stability and reliability of the to-be-supported member.

[0046] The foot structure 100 provided by the embodiment of the present application is provided with the damping member 120, so that when the support member vibrates, the damping member 120 can absorb and slow down part of the impact and vibration, reduce the impact and vibration transmitted to the mounting member 110 and the supported member, and further improve the stability and reliability of the supported member. The damping member 120 is rotatably connected with the inner wall of the first mounting groove 112 and rotatably connected with the support member, so that the damping member 120 can rotate relative to the mounting member 110 and the support member, and further change the inclination direction and angle of the damping member 120 relative to the vertical direction, so that the damping member 120 can buffer the vibration and impact in multiple directions, and the damping effect of the damping member 120 is improved. The first mounting groove 112 is arranged on the mounting member 110, and part of the damping member 120 is accommodated in the first mounting groove 112, so that the first mounting groove 112 can limit the damping member 120, and prevent the damping member 120 from rotating at too large an angle relative to the mounting member 110, which affects the stability of the damping member 120. In addition, the damping member 120 and the mounting member 110 in the embodiment of the present application are both located outside the supported member, without occupying the internal space of the supported member, and the volume of the supported member is reduced. At the same time, the structure of the supported member does not need to be redesigned, and the additional design cost is reduced.

[0047] In some embodiments, the number of mounting members 110 in the foot structure 100 is one, and the number of damping members 120 is multiple, and at least one of the stiffness and weight of each damping member 120 is different. The mounting member 110 is connected with the supported member, and different damping members 120 are connected with the mounting member 110, so that at least one of the stiffness and weight of the whole of the foot structure 100 and the supported member is different, and further the resonance frequency of the whole of the foot structure 100 and the supported member is different. Thus, the stiffness and weight of the preferred damping member 120 can be determined according to the external excitation frequency of the support member combined with finite element simulation analysis, so that the resonance frequency of the foot structure 100 and the supported member is staggered with the external excitation frequency, and further the foot structure 100 and the supported member avoid resonance with the external excitation, reduce the damage and influence caused by resonance on the foot structure 100 and the supported member, and improve the reliability of the foot structure 100.

[0048] In specific implementation, multiple damping members 120 with stiffness and weight arranged according to certain specification gradients can be connected with multiple mounting members 110, so as to form multiple foot structures 100 with different specifications. Thus, the foot structure 100 forms a series of standardized products, reduces the design cost and production cost of the foot structure 100, and simplifies the production process of the foot structure 100. In addition, the foot structure 100 forms a series of standardized products, so that it is more convenient to maintain and replace the foot structure 100 connected with the supported member. In specific use, the foot structure 100 with the preferred specification can be selected according to the results of mechanical simulation analysis.

[0049] It should be noted that the resonance frequency is the frequency at which a structure naturally vibrates under the action of external excitation. The resonance frequency is mainly related to the stiffness and weight of the structure. Generally, the relationship between mass and resonance frequency is inversely proportional, the greater the mass of the structure, the lower the resonance frequency. Generally, the stiffness and the resonance frequency are proportional. The higher the stiffness of the structure, the higher the resonance frequency. When the to-be-supported member is subjected to external excitation with the same or close to the resonance frequency, the to-be-supported member will vibrate greatly, affecting the stability of the to-be-supported member, and at the same time, it is easier to cause the structure, internal parts and connecting parts of the to-be-supported member to be damaged or broken by excessive stress.

[0050] In some embodiments, the vibration and impact received by the damping member 120 are mainly along the vertical direction, and the angle between the damping member 120 and the vertical direction is less than 45 degrees, so that the damping effect of the damping member 120 in the vertical direction is better than that in the horizontal direction, thereby facilitating the damping member 120 to slow down the impact and vibration in the vertical direction.

[0051] In specific implementation, the damping member 120 has a first connecting portion 122 and a second connecting portion 124, the first connecting portion 122 is rotationally connected with the inner wall of the first mounting groove 112, and the second connecting portion 124 is used to rotationally connect with the support member.

[0052] The second connecting portion 124 is located outside the first mounting groove 112, so as to facilitate the connection of the second connecting portion 124 with the support member.

[0053] For example, the first connecting portion 122 and the second connecting portion 124 are respectively located at two sections of the damping member 120.

[0054] Further, the third connecting portion 113 is arranged on the groove bottom of the first groove 112, and the first connecting portion 122 is rotationally connected with the third connecting portion 113.

[0055] In some embodiments, the first connecting portion 122 is a first spherical hinge, and / or the second connecting portion 124 is a second spherical hinge.

[0056] The first spherical hinge and the second spherical hinge are arranged to enable the damping member 120 to rotate relative to the mounting member 110 and the support member. In addition, the spherical hinge connection design is relatively simple, and the installation and disassembly are relatively convenient, and the maintenance cost is relatively low.

[0057] In some embodiments, the damping member 120 includes a housing 121, a telescopic rod 123, and a damping portion, the damping portion and part of the telescopic rod 123 are located in the housing, and the damping portion drives the telescopic rod 123 to extend and retract relative to the housing 121. One of the housing 121 and the telescopic rod 123 is rotationally connected with the inner wall of the first mounting groove 112, and the other is used to rotationally connect with the support member.

[0058] Exemplarily, the first connecting part 122 is arranged on the shell 121 and is rotationally connected with the inner wall of the first mounting groove 112. The second connecting part 124 is arranged on the distal end of the telescopic rod 123 away from the shell 121 and is rotationally connected with the support.

[0059] Specifically, when the impact and vibration on the support is transmitted to the damping member 120, the telescopic rod 123 is driven to extend or retract relative to the shell 121 through the damping part, so as to absorb the impact and vibration, and further slow down the impact and vibration transmitted from the damping member 120 to the mounting member 110 and the to-be-supported member.

[0060] In some embodiments, the second connecting part 124 is detachably connected with the support. By arranging the second connecting part 124 to be detachably connected with the support, the damping member 120 is detachably connected with the support, so that it is more convenient to install or detach the damping member 120 on / from the support, and further facilitate the maintenance and replacement of the foot structure 100.

[0061] It can be understood that the connection mode of the second connecting part 124 with the support can be clamping, threaded connection or other detachable connection mode.

[0062] In a specific implementation, the damping member 120 is a gas spring.

[0063] Specifically, the damping part is a gas arranged in the shell 121, and the telescopic rod 123 is driven to extend or retract relative to the shell 121 by the gas pressure of the gas. The gas spring has good buffering and damping performance, can effectively absorb and dissipate vibration and impact energy, and further protect the foot structure 100 and the to-be-supported member. At the same time, the gas spring can provide smooth and uniform force output, avoiding the dramatic change of force in the compression and expansion process.

[0064] In some embodiments, the damping member 120 can be other mechanical springs.

[0065] In some embodiments, the mounting member 110 includes a first mounting part 111 and a second mounting part 114. The first mounting part 111 has the first mounting groove 112 therein, the second mounting part 114 has the second mounting groove 115 therein, and the first mounting part 111 is connected with the inner wall of the second mounting groove 115. The second mounting part 114 is used to be connected with the to-be-supported member.

[0066] Specifically, the first mounting part 111 is located in the second mounting groove 115 and is connected with the inner wall of the second mounting groove 115. Specifically, the first mounting part 111 and the second mounting part 114 can be integrally formed. In this way, when the first mounting part 111 and the second mounting part 114 are integrally formed, the molding operation is facilitated.

[0067] Exemplarily, the first mounting groove 112 and the second mounting groove 115 are rectangular grooves, and the opening of the first mounting groove 112 faces the same side as the opening of the second mounting groove 115. The first mounting portion 111 is connected with the groove bottom of the second mounting groove 115. Further, the opening of the first mounting groove 112 can be flush with the opening of the second mounting groove 115. The first mounting portion 111 can be connected with the middle region of the groove bottom of the second mounting groove 115.

[0068] In some embodiments, the mounting member 110 further comprises a third mounting portion 116, which is connected with the middle region of the bottom surface of the first mounting portion 111 and the middle region of the groove bottom of the second mounting groove 115.

[0069] In some embodiments, the groove bottom of the first mounting groove 112 has a third connecting portion 113, which is a spherical recess. Part of the third connecting portion 113 is located on the middle region of the bottom surface of the first mounting groove 112, and part of the third connecting portion 113 is located on the middle region of the groove bottom of the second mounting groove 115. In this way, the first connecting portion 122 can be connected with the first mounting portion 111 and the second mounting portion 114 at the same time, and the connection between the first connecting portion 122 and the mounting member 110 is more stable and reliable.

[0070] In some embodiments, the foot structure 100 provided by the embodiments of the present application further comprises at least one counterweight, which is connected with at least one of the mounting member 110 and the damping member 120.

[0071] The weight and the number of the counterweight can be increased or decreased to change the weight of the foot structure 100, so as to change the resonance frequency of the foot structure 100 and the to-be-supported member as a whole, and thus the resonance frequency of the foot structure 100 and the to-be-supported member is staggered with the external excitation frequency.

[0072] Exemplarily, the counterweight can be detachably connected with at least one of the mounting member 110 and the damping member 120. By detachably connecting the counterweight with at least one of the mounting member 110 and the damping member 120, the counterweight can be easily installed and detached, and thus the weight of the foot structure 100 can be easily changed.

[0073] It can be understood that the material and shape of the counterweight can be adaptively set according to actual needs, which is not limited in the embodiments of the present application. The weight and the number of the counterweight can be determined according to the external excitation frequency in combination with finite element simulation analysis.

[0074] In a specific implementation, the counterweight has at least one first fixing part, at least one of the damping member 120 and the mounting member 110 has at least one second fixing part, and the first fixing part is connected to the second fixing part in correspondence. It can be understood that the first fixing part and the second fixing part can be connected by welding, clamping, threaded connection or other connection modes. Alternatively, the counterweight can be integrally formed with the mounting member 110 or the damping member 120.

[0075] For example, the second fixing part can be located on the side of the shell 121 of the damping member 120, so as to facilitate the connection of the counterweight and the damping member 120. Specifically, the counterweight is connected to the damping member 120 first, and then the damping member 120 is connected to the mounting member 110.

[0076] In some embodiments, the counterweight can be annular, and the counterweight is sleeved on the damping member 120.

[0077] In some embodiments, the mounting member 110 has a groove, and the counterweight is connected in the groove, so that the mounting member 110 and the counterweight are connected with good stability, and the structural consistency of the mounting member 110 and the counterweight is good.

[0078] In some embodiments, the mounting member 110 has at least one fourth mounting part, and the fourth mounting part is used to be connected with the to-be-supported member.

[0079] For example, the fourth mounting part can be fixedly connected with the to-be-supported member, so that the mounting member 110 and the to-be-supported member are connected with good stability. For example, the fourth mounting part can be one side of the mounting member 110, and the fourth mounting part can be bonded with the to-be-supported member.

[0080] In some embodiments, the fourth mounting part and the to-be-supported member can be detachably connected, so that the mounting member 110 and the to-be-supported member are detachably connected, so that the mounting member 110 is conveniently mounted on or detached from the to-be-supported member, thereby facilitating the maintenance and replacement of the foot structure 100. For example, the fourth mounting part and the to-be-supported member can be detachably connected by buckling, threading or the like.

[0081] Reference Figure 3 and Figure 4 On the basis of the above embodiments, the embodiment of the application provides a distribution box, which comprises a distribution box body and any foot structure 100 in the above embodiments, and the mounting member 110 of the foot structure 100 is connected with the distribution box body.

[0082] In the above embodiments, the specific structure of the foot structure 100 is described in detail, and will not be repeated here.

[0083] The distribution box body comprises a box body, an electrical connecting piece and a plurality of electronic components, each electronic component and at least part of the electrical connecting piece are connected in the box body, and the electrical connecting piece is connected with each electronic component in sequence.

[0084] The foot structure 100 is connected with the box body of the distribution box. The foot structure 100 is located on one side of the box body or below the box body and is connected with the box body to provide support for the box body. The foot structure 100 is connected outside the box body, avoiding connecting the foot structure 100 with the inside of the box body, thereby avoiding the need to redesign the distribution box, reducing the design and installation costs of the distribution box, without occupying the internal space of the box body, and without interfering with the electronic components and electrical connections inside the box body.

[0085] The connection between the foot structure 100 and the box body is the support stress position of the box body. In actual use, external impact and vibration are transmitted to the box body through the support and the foot structure 100 in sequence. Thus, the mechanical risk of the support stress position of the box body can be effectively reduced. By providing the damping member 120 on the foot structure 100, the external impact and vibration can be effectively buffered, reducing the impact and vibration transmitted to the box body, thereby protecting the box body.

[0086] In specific implementation, the number of foot structures 100 is multiple, and each foot structure 100 is connected with different positions of the box body. According to the position of the foot structure 100 and the external excitation frequency of the support, and combined with the finite element simulation analysis result, the stiffness and weight of the damping member 120 of each foot structure 100 can be designed and optimized, thereby effectively improving the buffering effect and damping effect of the distribution box on external excitation.

[0087] The distribution box provided by the embodiment of the present application sets the foot structure 100 to absorb and slow down part of the impact and vibration when the support vibrates, reducing the impact and vibration transmitted to the mounting member 110 and the supported member, thereby improving the stability and reliability of the supported member. By setting the damping member 120 to be rotatably connected with the inner wall of the first mounting groove 112 and rotatably connected with the support, the damping member 120 can rotate relative to the mounting member 110 and the support, thereby changing the inclination direction and angle of the damping member 120 relative to the vertical direction, so that the damping member 120 can buffer vibration and impact in multiple directions, improving the damping effect of the damping member 120.

[0088] In some embodiments, the distribution box body comprises a box body, and the box body is integrally formed with the mounting member 110.
