[0036] The exemplary embodiments will be described in detail below, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached 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 the distribution box is installed on the bottom plate of the battery pack by connecting the first threaded holes with the second threaded holes in sequence through a plurality of screws. However, the screw connection is a rigid connection, and vibration and impact are basically not dissipated on the screws. Therefore, when the above-mentioned bottom plate vibrates, the vibration on the bottom plate will be completely transmitted to the distribution box through the screws, affecting the stability and reliability of the distribution box.
[0038] Based on this, an embodiment of the present application provides a support leg structure, including a support member and at least one vibration damper. The support member is used to connect with the member to be supported, and the support member has at least one first mounting groove, and the vibration damper is correspondingly rotatably connected in the first mounting groove, and the vibration damper at least partially extends out of the first mounting groove for rotational connection with the support member. By setting the vibration damper, when the support member vibrates, the vibration damper absorbs and mitigates part of the impact and vibration, thereby reducing the impact and vibration transmitted to the mounting member and the member to be supported, thereby improving the stability and reliability of the member to be supported. By setting the vibration damper to be rotatably connected to the inner wall of the first mounting groove, the vibration damper is rotatably connected to the support member, so that the vibration damper can rotate relative to the mounting member and the support member, thereby changing the inclination direction and angle of the vibration damper relative to the vertical direction, so that the vibration damper can buffer vibrations and impacts in multiple directions, thereby improving the vibration damping effect of the vibration damper. By arranging a first mounting groove on the mounting member, the first mounting groove accommodates part of the vibration damping member, so as to limit the vibration damping member through the first mounting groove, thereby preventing the vibration damping member from rotating too much relative to the mounting member and affecting the stability of the vibration damping member.
[0039] The embodiments of the present application are described below with reference to the accompanying drawings.
[0040] Reference Figure 1 and Figure 2 The present application provides a support leg structure 100 for connecting a member to be supported and a support member supporting the member to be supported, and includes: a mounting member 110 and at least one vibration-damping member 120. The mounting member 110 is used to connect with the member to be supported, and the mounting member 110 has at least one first mounting groove 112. The vibration-damping member 120 is rotatably connected to the inner wall of the first mounting groove 112, and the vibration-damping member 120 at least partially extends out of the first mounting groove 112 for rotatably connecting with the support member. The vibration-damping member 120 is used to reduce vibration and impact on the support member.
[0041] Exemplarily, the support member is located above the support member. The first mounting groove 112 is a rectangular groove, and the first mounting groove 112 has an opening, and the vibration damping member 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, that is, the opening faces the support member, so that the vibration damping member 120 is rotatably connected to the support member. Furthermore, the bottom of the first mounting groove 112 is opposite to the opening of the first mounting groove 112, and the first connecting portion 122 is rotatably connected to the bottom of the first mounting groove 112, so that the connection between the vibration damping member 120 and the first mounting groove 112 is more stable.
[0042] Specifically, one end of the vibration damper 120 is located in the first mounting groove 112 and is rotatably connected to the inner wall of the first mounting groove 112, so that the vibration damper 120 can rotate relative to the mounting member 110. The other end of the vibration damper 120 extends out of the first mounting groove 112 and is rotatably connected to the support member, so that the vibration damper 120 can rotate relative to the support member. The vibration damper 120 rotates relative to the mounting member 110 and the support member to adjust the tilt direction and angle of the vibration damper 120 relative to the vertical direction, so that the vibration damper 120 can reduce vibrations and impacts on the support member in different directions.
[0043] It is understandable that when installing the vibration damper 120, the angle between the vibration damper 120 and the vertical direction can be adjusted to adjust the vibration damping effect of the vibration damper 120 in the vertical and horizontal directions, so that the vibration damping effect of the vibration damper 120 in the required vibration damping direction during actual use is better.
[0044] In some embodiments, the vibration damper 120 is located in the first mounting groove 112, and the vibration damper 120 is inclined relative to the groove bottom and at least two groove surfaces of the first mounting groove 112, and is not perpendicular. The groove bottom of the first mounting groove 112 is parallel to the horizontal plane, so that the vibration damping effect of the vibration damper 120 can be decomposed into three directions, thereby improving the vibration damping effect of the vibration damper 120.
[0045] In a specific implementation, the impact and vibration on the support member will be transmitted to the support foot structure 100. By setting the shock-absorbing member 120 to absorb part of the impact and vibration, the impact and vibration transmitted from the support foot structure 100 to the member to be supported are reduced, thereby protecting the member to be supported and ensuring the stability and reliability of the member to be supported.
[0046] The support leg structure 100 provided in the embodiment of the present application is provided with a vibration damper 120, so that when the support member vibrates, the vibration damper 120 absorbs and mitigates part of the impact and vibration, reduces the impact and vibration transmitted to the mounting member 110 and the member to be supported, and thus improves the stability and reliability of the member to be supported. By providing the vibration damper 120 to be rotatably connected to the inner wall of the first mounting groove 112, the vibration damper 120 is rotatably connected to the support member, so that the vibration damper 120 can rotate relative to the mounting member 110 and the support member, thereby changing the inclination direction and angle of the vibration damper 120 relative to the vertical direction, so that the vibration damper 120 can buffer vibrations and impacts in multiple directions, thereby improving the vibration damping effect of the vibration damper 120. By providing the first mounting groove 112 on the mounting member 110, the first mounting groove 112 accommodates part of the vibration damping member 120, so as to limit the vibration damping member 120 through the first mounting groove 112, thereby preventing the vibration damping member 120 from rotating too much relative to the mounting member 110 and affecting the stability of the vibration damping member 120. In addition, the vibration damping member 120 and the mounting member 110 in the embodiment of the present application are both located outside the member to be supported, without occupying the internal space of the member to be supported, thereby reducing the volume of the member to be supported. At the same time, there is no need to redesign the structure of the member to be supported, thereby reducing additional design costs.
[0047] In some embodiments, the number of mounting members 110 in the support foot structure 100 is one, the number of vibration damping members 120 is multiple, and at least one of the stiffness and weight of each vibration damping member 120 is different. By connecting the mounting member 110 to the member to be supported, and connecting different vibration damping members 120 to the mounting member 110, at least one of the stiffness and weight of the support foot structure 100 and the member to be supported as a whole is different, thereby making the resonance frequency of the support foot structure 100 and the member to be supported as a whole different. Therefore, the stiffness and weight of the preferred vibration 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 support foot structure 100 and the member to be supported is staggered with the external excitation frequency, thereby avoiding resonance between the member to be supported and the support foot structure 100 and the external excitation, reducing the damage and influence of the resonance on the member to be supported and the support foot structure 100, and improving the reliability of the support foot structure 100.
[0048] In specific implementation, multiple vibration damping members 120 arranged in a certain specification gradient according to stiffness and weight can be connected to multiple mounting members 110 to form multiple foot structures 100 of different specifications. In this way, the foot structure 100 forms a series of standardized products, which 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, which makes it more convenient to repair and replace the foot structure 100 connected to the support member. In specific use, the foot structure 100 of the preferred specifications can be selected according to the results of mechanical simulation analysis.
[0049] It should be noted that the resonant frequency is the frequency at which a structure naturally vibrates under external excitation. The resonant frequency is mainly related to the stiffness and weight of the structure. Usually, the relationship between mass and resonant frequency is inversely proportional. The greater the mass of the structure, the lower the resonant frequency. Usually, there is a direct proportional relationship between stiffness and resonant frequency. The higher the stiffness of the structure, the higher the resonant frequency. When the support member is subjected to an external excitation that is the same or close to its resonant frequency, the support member will vibrate significantly, affecting the stability of the support member. At the same time, it is more likely to cause the structure, internal components and connecting components of the support member to be subjected to excessive stress and be damaged or broken.
[0050] In some embodiments, the vibration and impact to which the shock absorber 120 is subjected are mainly along the vertical direction, and the angle between the shock absorber 120 and the vertical direction is less than 45 degrees, so that the shock absorber 120 has a better vibration reduction effect in the vertical direction than the shock absorber 120 in the horizontal direction, thereby facilitating the shock absorber 120 to reduce the impact and vibration in the vertical direction.
[0051] In a specific implementation, the vibration damping member 120 has a first connecting portion 122 and a second connecting portion 124 . The first connecting portion 122 is rotatably connected to the inner wall of the first mounting groove 112 , and the second connecting portion 124 is used to be rotatably connected to the support member.
[0052] The second connection portion 124 is located outside the first installation groove 112 to facilitate the connection between the second connection portion 124 and the support member.
[0053] Exemplarily, the first connection portion 122 and the second connection portion 124 are respectively located at two sections of the vibration damping member 120 .
[0054] Furthermore, a third connection portion 113 is provided on the bottom of the first groove 112 , and the first connection portion 122 is rotatably connected to the third connection portion 113 .
[0055] In some embodiments, the first connection portion 122 is a first ball joint, and / or the second connection portion 124 is a second ball joint.
[0056] The first ball joint and the second ball joint are provided so that the vibration reducing member 120 can rotate relative to the mounting member 110 and the supporting member. In addition, the design of the ball joint connection is relatively simple, and the installation and disassembly are relatively convenient, and the maintenance cost is low.
[0057] In some embodiments, the vibration damping member 120 includes a housing 121, a telescopic rod 123 and a vibration damping portion, wherein the vibration damping portion and a portion of the telescopic rod 123 are located in the housing, and the vibration 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 rotatably connected to the inner wall of the first mounting groove 112, and the other is used to be rotatably connected to the support member.
[0058] Exemplarily, the housing 121 has a first connection portion 122, which is rotatably connected to the inner wall of the first mounting groove 112. The telescopic rod 123 has a second connection portion 124 at one end away from the housing 121, which is rotatably connected to the support member.
[0059] Specifically, when the impact and vibration on the support member are transmitted to the vibration damping member 120, the telescopic rod 123 is driven to extend or retract relative to the shell 121 through the vibration damping part to absorb the impact and vibration, thereby reducing the impact and vibration transmitted from the vibration damping member 120 to the mounting member 110 and the member to be supported.
[0060] In some embodiments, the second connection portion 124 is detachably connected to the support member. By providing the second connection portion 124 to be detachably connected to the support member, the vibration damping member 120 is detachably connected to the support member, so that it is convenient to install the vibration damping member 120 on the support member or to remove the vibration damping member 120 from the support member, thereby facilitating the maintenance and replacement of the support leg structure 100.
[0061] It can be understood that the second connection portion 124 and the support member may be connected in a snap-on, threaded or other detachable connection manner.
[0062] In a specific implementation, the vibration damping member 120 is a gas spring.
[0063] The vibration reduction part is a gas disposed in the housing 121, and the gas pressure drives the telescopic rod 123 to expand and contract relative to the housing 121. The gas spring has good buffering and vibration reduction performance, and can effectively absorb and dissipate vibration and impact energy, thereby protecting the support leg structure 100 and the supported member. At the same time, the gas spring can provide a smooth and uniform force output, avoiding drastic changes in force during compression and extension.
[0064] In some embodiments, the vibration dampening member 120 may be other mechanical springs.
[0065] In some embodiments, the mounting member 110 includes a first mounting portion 111 and a second mounting portion 114. The first mounting portion 111 has a first mounting groove 112, the second mounting portion 114 has a second mounting groove 115, and the first mounting portion 111 is connected to the inner wall of the second mounting groove 115. The second mounting portion 114 is used to connect to the supported member.
[0066] The first mounting portion 111 is located in the second mounting groove 115 and connected to the inner wall of the second mounting groove 115. Specifically, the first mounting portion 111 and the second mounting portion 114 can be integrally formed. In this way, when the first mounting portion 111 and the second mounting portion 114 are integrally formed, the molding operation is facilitated.
[0067] Exemplarily, the first mounting groove 112 and the second mounting groove 115 are both rectangular grooves, and the opening of the first mounting groove 112 and the opening of the second mounting groove 115 face the same side. The first mounting portion 111 is connected to the groove bottom of the second mounting groove 115. Further, the opening of the first mounting groove 112 may be flush with the opening of the second mounting groove 115. The first mounting portion 111 may be connected to the middle area of the groove bottom of the second mounting groove 115.
[0068] In some embodiments, the mounting member 110 further includes a third mounting portion 116 , which connects a middle area of the bottom surface of the first mounting portion 111 and a middle area of the bottom of the second mounting groove 115 .
[0069] In some embodiments, the bottom of the first mounting groove 112 has a third connection portion 113, the third connection portion 113 is a spherical groove, part of the third connection portion 113 is located in the middle area of the bottom surface of the first mounting groove 112, and part of the third connection portion 113 is located in the middle area of the bottom of the second mounting groove 115. Thus, the first connection portion 122 can be connected to the first mounting portion 111 and the second mounting portion 114 at the same time, thereby making the connection between the first connection portion 122 and the mounting member 110 more stable and reliable.
[0070] In some embodiments, the support leg structure 100 provided in the embodiments of the present application further includes at least one counterweight, which is connected to at least one of the mounting member 110 and the vibration-absorbing member 120 .
[0071] The weight of the support foot structure 100 is changed by increasing or decreasing the weight and number of the counterweights, thereby changing the overall resonance frequency of the support foot structure 100 and the part to be supported, thereby causing the resonance frequency of the support foot structure 100 and the part to be supported to be offset from the external excitation frequency.
[0072] Exemplarily, the counterweight may be detachably connected to at least one of the mounting member 110 and the vibration reducing member 120. By making the counterweight detachably connected to at least one of the mounting member 110 and the vibration reducing member 120, it is convenient to install and remove the counterweight, thereby facilitating changing the weight of the foot structure 100.
[0073] It is understandable that the material and shape of the counterweight can be set according to actual needs, and the embodiment of the present application does not limit this. The weight and number of the counterweight can be determined according to the external excitation frequency combined with finite element simulation analysis.
[0074] In a specific implementation, the counterweight has at least one first fixing portion, and at least one of the vibration damping member 120 and the mounting member 110 has at least one second fixing portion, and the first fixing portion is connected to the second fixing portion accordingly. It can be understood that the connection between the first fixing portion and the second fixing portion can be welding, clamping, threaded connection or other connection methods. Alternatively, the counterweight can be integrally formed with the mounting member 110 or the vibration damping member 120.
[0075] For example, the second fixing portion may be located on the peripheral side of the housing 121 of the vibration damper 120, so as to facilitate the connection between the counterweight and the vibration damper 120. Specifically, the counterweight is first connected to the vibration damper 120, and then the vibration damper 120 is connected to the mounting member 110.
[0076] In some embodiments, the counterweight may be ring-shaped and is sleeved on the vibration reducing member 120 .
[0077] In some embodiments, the mounting member 110 has a groove, and the counterweight is connected in the groove, so that the connection between the mounting member 110 and the counterweight is more stable and the structural consistency between the mounting member 110 and the counterweight is better.
[0078] In some embodiments, the mounting member 110 has at least one fourth mounting portion, and the fourth mounting portion is used to connect to the member to be supported.
[0079] Exemplarily, the fourth mounting portion can be fixedly connected to the supported member to ensure better stability of the connection between the mounting member 110 and the supported member. For example, the fourth mounting portion can be a side surface of the mounting member 110, and the fourth mounting portion can be bonded to the supported member.
[0080] In some embodiments, the fourth mounting portion and the member to be supported may be connected in a detachable manner. By providing a detachable connection between the mounting portion and the member to be supported, the mounting member 110 and the member to be supported can be detachably connected, so that it is convenient to install the mounting member 110 on the member to be supported or to remove the mounting member 110 from the member to be supported, thereby facilitating the maintenance and replacement of the support leg structure 100. For example, the fourth mounting portion and the member to be supported can be detachably connected by a buckle, a thread, etc.
[0081] Reference Figure 3 and Figure 4 On the basis of the above embodiments, an embodiment of the present application provides a distribution box, comprising: a distribution box body and any one of the support leg structures 100 in the above embodiments, and a mounting member 110 of the support leg structure 100 is connected to the distribution box body.
[0082] The specific structure of the support leg structure 100 has been described in detail in the above embodiment and will not be repeated here.
[0083] The distribution box body comprises a box body, electrical connectors and a plurality of electronic components. Each electronic component and at least part of the electrical connectors are connected in the box body, and the electrical connectors are connected to each electronic component in turn.
[0084] The support leg structure 100 is connected to the box body of the distribution box. The support leg structure 100 is located on one side of the box body or below the box body and is connected to the box body to provide support for the box body. The support leg structure 100 is connected to the outside of the box body, avoiding connecting the support leg structure 100 to the inside of the box body, thereby avoiding redesigning the distribution box, reducing the design cost and installation cost of the distribution box, and does not need to occupy the internal space of the box body, and will not interfere 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 supporting force bearing part of the box body. In actual use, external impact and vibration are transmitted to the box body through the support member and the foot structure 100 in sequence. Therefore, the mechanical risk of the supporting force bearing part of the box body can be effectively reduced. By arranging the vibration damping member 120 on the foot structure 100, it can effectively buffer the external impact and vibration, so that the impact and vibration transmitted to the box body are reduced, thereby protecting the box body.
[0086] In a specific implementation, there are multiple support leg structures 100, and each support leg structure 100 is connected to a different position of the box body.
