[0030] like Figures 1-8 As shown in the figure, this application provides an intelligent charging management device for lighting equipment, including a cabinet 1. The cabinet 1 is assembled from a back panel, side panels, cabinet doors, and multiple partitions. The interior of the cabinet 1 is divided into multiple charging compartments 2 by the partitions, and each charging compartment corresponds to a cabinet door 14. In each charging compartment 2, a socket panel 3 is provided on the partition. The socket panel 3 is equipped with multiple charging interfaces, including various types such as direct-plug interfaces 5 and USB interfaces 6. The number and type of charging interfaces can be flexibly configured according to actual usage needs. Some or all of the charging interfaces can adopt fast charging technology and a device sensing and recognition system, which can quickly charge the identified and adapted electrical equipment. The socket panel 3 is also provided with a timer socket 4. When the timer socket 4 is not activated, the charging interfaces can be used for any duration. When the timer socket 4 is activated, the charging interfaces on the socket panel 3 can only be used for a set time, saving power during off-peak hours and protecting the equipment. Each partition is provided with an electrical isolation layer 19 to isolate the electrical connection between the charging compartments 2 and improve charging safety.

[0031] In some embodiments, in order to facilitate charging of medium or large lighting devices and other types of electrical devices, a plurality of external charging interfaces 15 are provided on the side plates of the cabinet 1, and handles 16 are also provided on the side plates to facilitate movement of the device. The universal wheels 10 are installed at the bottom of the cabinet 1, and the universal wheels 10 are fixedly installed on the bottom of the cabinet 1 through the support 11, which facilitates the overall movement of the device.

[0032] The bottom of the cabinet 1 is provided with a buckle type rail drawer 18 for placing various lighting devices (such as various lighting lamps, etc.). The buckle type rail drawer is slidably connected to the bottom of the cabinet through a rail, and the side of the drawer is provided with a buckle for locking.

When unlocking, the drawer can be easily taken out by gently pressing or pulling the unlocking button, which is convenient to operate.

[0033] In some embodiments, the charging compartment 2 is provided with an aerosol fire extinguishing capsule 20, a smoke sensor 22, a temperature sensor 21, an alarm unit 23, and a main controller.

When the smoke sensor detects that the smoke concentration reaches the preset concentration threshold, the main controller controls the alarm unit 23 to issue a smoke alarm. When it is judged that a fire may occur according to the temperature value collected by the temperature sensor and the smoke concentration value collected by the smoke sensor, the main controller controls the alarm unit 23 to issue a fire warning.

[0035] In some embodiments, in order to facilitate the overall movement of the device, the overall device should be as light as possible under the condition of ensuring the stability of the structure and the safety of use, and the device should have good heat dissipation function during use to ensure the safety of multiple lighting devices and other electrical equipment during charging. As shown in Figure 9 In this embodiment, the topological optimization method is used to design the partition plate and the back plate structure of the device based on the finite element software, and the topological optimization method includes:

[0036] S901: Divide the to-be-optimized region of the cabinet body into a plurality of finite element units, and define the design variable of each finite element unit as material density;

[0037] In this embodiment, the back plate and the partition plate of the cabinet body are taken as the to-be-optimized objects, the to-be-optimized objects are modeled in the finite element software, the key stress region of the to-be-optimized objects is taken as the to-be-optimized region, and is discretized into N finite element units. The design variable of each finite element unit is defined and represented as x i ∈ [x mim , 1], x i is the design variable of the finite element unit i, x i = 1 indicates that the material completely exists in the finite element unit i, x i = x min is used to avoid numerical singularity in the topological optimization process, for example, x min = 10 -3 , and the number of finite element units can be 240*480.

[0038] S902: Define the material properties and material interpolation model of the to-be-optimized region, and set the load parameters of the to-be-optimized region;

[0039] In this embodiment, the cabinet body is made of structural steel, and in the finite element analysis, the material properties of the to-be-optimized objects are set to structural steel. The specific material parameters are: Young's modulus E0=210 GPa, Poisson's ratio υ=0.3, thermal expansion coefficient α=12*10 -6 ℃ -1 , thermal conductivity k=45 W / (m·K), and specific heat capacity c p =500 J / (kg·K). The material stiffness of the finite element unit is interpolated by using the SIMP (Solid Isotropic Material with Penalization) density stiffness interpolation model, and the interpolation model is represented as:

[0040]

[0041] Wherein, p is a penalty factor, which can be p=3, and the environment temperature is 25°C.

[0042] In some embodiments, the total load borne by the region to be optimized includes two parts, i.e., a static load corresponding to the pressure borne by the stored articles and a thermal load corresponding to the thermal stress borne by the structural steel due to the heat generated during the charging process. Therefore, the configured load parameters include a static load parameter and a thermal load parameter. Considering that the cabinet body needs to have a heat dissipation function, fluid dynamics is introduced into the topology optimization process during simulation. By jointly modeling the thermal, mechanical and fluid multi-physical fields, the influence of air flow on heat dissipation is considered while the region to be optimized is under load, the real stress condition of the cabinet body during long-term use is simulated, the cabinet body structure and the shape of the heat dissipation channel are optimized, efficient thermal management is realized, and the heat dissipation performance of the device is improved.

[0043] In some ways, the pressure generated by the stored articles in the cabinet body is P = 5000 N / m 2 , the area of the finite element unit i is A i = 1 x 10 -6 m 2 , the approximate static load applied is f i,mech = P · A i = 5 x 10 -3 N. The local temperature rise caused by the heat generated by the battery during the charging process is ΔT = 5°C, and the thermal stress borne by the structural steel is σ th = E0·α·ΔT = 12.6 MPa. Assuming that each finite element unit is subjected to uniform thermal stress, the equivalent stress of the thermal load acting on the finite element unit i is f i,thermal = σ th · A i = 12.6 x 10 -3 N. The total load borne by each finite element unit is the superposition of the static load and the thermal load, which is represented as f i = f i,mech + f i,thermal = 17.6 x 10 -3 N.

[0044] S903: Construct a multi-objective topology optimization model and set constraint conditions;

[0045] In this embodiment, considering multiple factors such as the structural safety, weight, heat dissipation performance, etc. of the intelligent charging management device, a multi-objective topology optimization model is constructed, which is represented as:

[0046] min S e = min (ω1C + ω2R th ) (2)

[0047] wherein S e is the weight sum of the structural compliance and thermal resistance, C is the structural compliance, R th is the thermal resistance, and ω1 and ω2 are the weight values of the structural compliance and the thermal resistance.

[0048] The structural compliance can be expressed as:

[0049]

[0050] where u i is the displacement vector of the finite element unit i, K i 0 is the element stiffness matrix of the finite element unit i in the full material state, which can be pre-set, and f is the global load vector.

[0051] The constraints set include force balance constraints, volume fraction constraints, and design variable range constraints. The design variable range constraint is that x i ∈ [x min , 1]. The volume fraction constraint is the maximum allowable volume V * of the region to be optimized, which is expressed as:

[0052]

[0053] where v i is the volume of the finite element unit i. Optionally, V * may be set to 50% of the entire region to be optimized.

[0054] The force balance constraint is that the displacement and load of the structure should satisfy the balance relationship, which is expressed as:

[0055] K(x)·u=f (5)

[0056] where K(x) is the global stiffness matrix, u is the global displacement matrix, and f is the global load matrix. The global load matrix f is the sum of the total loads of all finite element units, which is expressed as:

[0057]

[0058] The global stiffness matrix K(x) is composed of the stiffness matrices K i of each finite element unit through the finite element assembly process, that is, the global stiffness matrix is the sum of the stiffness matrices of all finite element units, which is expressed as:

[0059]

[0060] The stiffness matrix K i of each finite element unit is related to the material density x i of the finite element unit, and their relationship can be described by the SIMP method as:

[0061]

[0062] The stiffness matrix K iThe response of the finite element cell to an external load is described as:

[0063]

[0064] where B is a strain-displacement matrix relating strain to displacement, D is a material constitutive matrix describing the elastic properties of the material, Ω i is the domain of the finite element cell i, and dΩ is the integral over the cell domain.

[0065] The strain-displacement matrix B can be calculated from the shape functions of the finite element cell. If the finite element cell is a square cell, its strain-displacement matrix B can be expressed as:

[0066]

[0067] where N1, N2, N3, N4 are the shape functions of the four nodes of the square finite element cell, ξ and η are the isoparametric coordinate system within the finite element cell, is the partial derivative of the shape function of the jth node of the finite element cell with respect to the parameters ξ and η.

[0068] The material constitutive matrix D can be expressed as:

[0069]

[0070] S904: Based on the multi-objective topology optimization model and the constraint condition, the structural response of the to-be-optimized region is solved by using finite element analysis under the predetermined material variable;

[0071] In this embodiment, the structural response of the to-be-optimized region is solved by using finite element analysis. When solving, the total load borne by each finite element cell in the to-be-optimized region can be calculated according to the load parameter of the to-be-optimized region set, and the global load matrix f of the to-be-optimized region is calculated according to formula (6); when the material variable is set, the global stiffness matrix can be calculated according to formulas (7) and (8); the global displacement matrix u is calculated according to formula (5) according to the global load matrix and the global stiffness matrix, and then the displacement vector u i of each finite element cell can be determined, the structural flexibility C is calculated according to formula (3), the strain ε i of each finite element cell is calculated according to the displacement vector u i of each finite element cell according to formula ε i = Bu i , the stress σ i of each finite element cell is calculated according to the constitutive relation formula σ i = D(ε thermal - ε i , where ε thermalFor thermal strain, the thermal strain formula ε thermal = αΔT can be used to determine.

[0072] In some embodiments, according to Fourier's law, the control equation of steady-state heat conduction can be obtained as:

[0073]

[0074] where k is the thermal conductivity of the material, is the temperature gradient, and Q is the heat source term.

[0075] For the heat dissipation structure of the cabinet body, the thermal resistance R th can be defined as:

[0076]

[0077] where ΔT is the difference between the highest temperature T max inside the cabinet body and the ambient temperature T ambient , i.e., ΔT = T max - T ambient ; P heat is the total heat generation power generated by the charging system, which can be taken as P heat = 100 W, for example. In the simulation analysis, the highest temperature, the ambient temperature, and the total heat generation power can be set, and the thermal resistance can be determined by calculation.

[0078] In some embodiments, for the weight values ω1 and ω2 in the multi-objective topology optimization model, the importance of the structural flexibility and the thermal resistance can be considered. Since the structural flexibility is related to the structural stiffness, a higher stiffness needs to be maintained to ensure the safety, stability, and carrying capacity of the intelligent charging management device during the charging process, and the importance of the structural flexibility is higher, so a larger weight value can be set. The thermal resistance is an important indicator affecting the heat dissipation efficiency of the cabinet body, but its importance is lower than that of the structural flexibility, so a smaller weight value can be set. In some ways, the weight values corresponding to the structural flexibility and the thermal resistance can be taken as: ω1 = 0.8 and ω2 = 0.2.

[0079] S905: Calculate the sensitivity value of the multi-objective topology optimization model to the design variable;

[0080] In this embodiment, to measure the influence of the design variable on the optimization objective, the reciprocal sensitivity method is used to calculate the sensitivity of the multi-objective topology optimization model to each design variable x i , which is represented as:

[0081]

[0082] To prevent the chessboard phenomenon from occurring in the topology optimization process, when calculating the sensitivity value, the sensitivity filtering method is used to weight the adjacent finite element units according to the distance of the finite element units.

[0083] In some ways, the distance weighting function adopts a Gaussian function, denoted as:

[0084]

[0085] where ω ij is the weight value between finite element unit i and finite element unit j, d ij is the distance between finite element unit i and finite element unit j, and σ is the standard deviation of Gaussian distribution, which controls the scale of similarity. According to formula (15), the smaller the distance d ij , the larger the weight value ω ij . Using Gaussian function for filtering can ensure that the influence weight of the adjacent area on the sensitivity value gradually decreases instead of suddenly dropping, thereby forming a continuous and smooth design. At the same time, introducing the distance d ij can make the data error of the filtering process more stable, which meets the topology optimization goal.

[0086] In the finite element grid, the influence degree of the sensitivity of finite element unit j in the neighborhood on the sensitivity of finite element unit i is determined by the weight value ω ij . The sensitivity filtering method for filtering the sensitivity value can be expressed as:

[0087]

[0088] where S is the filtered sensitivity, S is the sensitivity of finite element unit j, and Π i is the field set of finite element unit i.

[0089] S906: Using optimality criteria method to update the design variable according to the sensitivity value;

[0090] In this embodiment, the optimality criteria method is used to update the design variable, which is denoted as:

[0091]

[0092] where x is the design variable of finite element unit i in the k+1 iteration, is the design variable of finite element unit i in the k iteration, λ is the Lagrange multiplier, and v i is the volume of finite element unit i. Updating the design variable based on the sensitivity value filtered by Gaussian can effectively reduce the occurrence of chessboard phenomenon and improve the calculation accuracy and stability.

[0093] S907: It is judged whether the preset convergence condition is reached. If not, the multi-objective topology optimization model is updated based on the updated design variable, the structural response of the to-be-optimized region is solved by using finite element analysis, the sensitivity value corresponding to the updated design variable is calculated, and the design variable is updated according to the sensitivity value. The steps are repeated until the convergence condition is reached.

[0094] In this embodiment, the optimization design is realized by iteration in the finite element analysis process, the convergence condition is set, and the iteration is stopped when the convergence condition is reached in the iteration process, and the topology optimization result is output. If the convergence condition is not reached, the design variable is updated in each iteration, the multi-objective topology optimization model is updated according to the updated design variable, the structural response of the to-be-optimized region is solved by using finite element analysis based on the updated multi-objective topology optimization model and the constraint condition, the filtered sensitivity value of the updated design variable is calculated, the design variable is updated according to the updated sensitivity value, and the above iteration process is repeated until the convergence condition is reached.

[0095] In some embodiments, the convergence condition can be that the upper limit of the number of iterations (for example, several hundred times) is set, or the average change rate of the design variable is less than a preset change threshold. The average change rate of the design variable is the average value of the difference of the design variable of each finite element unit in two adjacent iterations, and is expressed as:

[0096]

[0097] where Δx avg is the average change rate of the design variable. The average change rate of the design variable is calculated after each iteration, and if the average change rate is less than the set change threshold, it is determined that the convergence condition is met, and the iteration is stopped. Optionally, the change threshold can be set to 10 -3 .

[0098] In some embodiments, the cabinet body, the back plate and the partition plate are designed according to the above topology optimization method. On the one hand, the back plate and the partition plate reduce the overall weight of the device and reduce material loss while ensuring structural strength and rigidity, facilitating the overall movement of the device. According to the set target, the mass of the partition plate can be reduced to 50% of the original mass without reducing the maximum load. On the other hand, in combination with factors such as heat conduction, thermal stress and thermal deformation generated during charging, the back plate is designed with a uniformly distributed louvered heat dissipation structure 17, the partition plate is provided with a plurality of heat dissipation holes 7 and a specific shape of weight reduction holes 8, and a large area of the heat dissipation area can maximize the air flow. The heat dissipation structure of the partition plate between the back plate and the charging bin can achieve good collaborative heat dissipation effect, effectively reduce the temperature in the cabinet body, and improve the heat dissipation capacity of the cabinet body, thereby ensuring the charging safety.

[0099] The intelligent charging management device provided by the embodiment can effectively reduce the overall quality of the device, facilitate the overall moving of the cabinet, and thus can be deployed at different positions according to needs, to meet the construction needs of different places; the cabinet is designed with a reasonable heat dissipation structure, which can effectively reduce the temperature in the cabinet and improve the charging safety; the device can be configured with different types of charging interfaces inside and outside the cabinet according to charging needs, which is convenient to use and can meet the charging needs of various lighting equipment and other electrical equipment; various monitoring sensors are configured in the cabinet to ensure the use safety of the device; the intelligent query, control and management of the device can be realized by using the charging management control system, which is convenient to operate and improves the experience.
