Therefore, they should not be construed as limitations on this utility model.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1: As Figures 1 to 4 As shown, an integrated OPS electrical box mainly consists of a box body 1, a box cover 6, an OPS circuit board 2, a relay 4, and a fuse 3. To facilitate inspection and maintenance of the internal components, the box body 1 and the box cover 6 are designed as detachable structures, specifically, they can be connected by bolts or other means. To protect the internal components and reduce the impact of the external environment, the box cover 6 is fitted to the box body 1, allowing it to close and form an installation space at the opening of the box body 1. The OPS circuit board 2 integrates an OPS control chip 2-1, which serves as a carrier for electronic components. Through the combination and arrangement of these components, specific functions and controls are achieved.

[0026] The OPS circuit board 2, the relay 4 and the fuse 3 are all installed in the box body 1. In order to arrange the components in the electric appliance box in order, facilitate observation by maintenance personnel, etc., a relay slot and a fuse slot are arranged on the OPS circuit board 2. The relay slot and the fuse slot are both multiple, and the relay 4 and the fuse 3 are also multiple. The relay 4 can be directly plugged into the relay slot, and the fuse 3 can be directly plugged into the fuse slot. The circuit with multiple fuses 3 and multiple relays 4 is integrated and designed to realize the control function of the OPS electric appliance box.

[0027] The box body 1 has multiple interfaces 7 electrically connected to the OPS circuit board 2. The interface 7 allows quick and convenient connection and disconnection of the circuit, facilitating installation, maintenance and repair work, so that the OPS electric appliance box can be easily connected with external circuits or devices without complex welding or fixed connection. By using the interface 7, the connection and disconnection of the circuit can be performed without directly operating the main power line, reducing the risk of electric shock and the danger of operation. The interface 7 is multiple, one of which is an OPS interface 8. The OPS function on the existing internal combustion fork truck is usually realized by separately adding an OPS control box according to customer demand, which occupies a lot of vehicle space and is not economical. Although there are integrated OPS electric appliance boxes in the industry, the OPS function cannot be cancelled. The demand for fork trucks in underdeveloped countries often only requires economy and practicality, and does not require OPS and other related functions. Additional selection of electric appliance boxes and design of wiring harnesses is often required, which greatly increases the research and development design time and cost, thereby causing the production cost of internal combustion fork trucks to be high, increasing the use cost of users, and affecting the promotion and application of internal combustion fork trucks in the market. In order to solve the above technical problems, the integrated OPS electric appliance box in the embodiment arranges the OPS function and the fuse box relay control circuit required by the traditional electric appliance box together by integrating the circuit, which can meet the use of different types of engines. Since it is improved on the basis of the existing electric appliance box, it can meet the OPS function requirement through the additional OPS interface 8, and the plug-in type and pin definition are not changed, so that the OPS electric appliance box has good interchangeability to meet different use requirements and reduce use cost. At the same time, by integrating the OPS function on the existing electric appliance box, the space occupied by the electric appliance box can also be reduced.

[0028] The OPS interface 8 in the embodiment is provided in a screwing mode, specifically, an internal thread can be designed at the OPS interface 8, and an external thread structure matched with the internal thread is formed at the to-be-plugged member, so that the connection of the OPS interface 8 and the to-be-plugged member is realized; conversely, an external thread can be designed at the OPS interface 8, and an internal thread structure matched with the external thread is formed at the to-be-plugged member, so that the connection of the OPS interface 8 and the to-be-plugged member is also realized, and the use requirement is met.

[0029] The OPS interface 8 is connected to the OPS circuit board 2 through the connection line 9, in order to reduce the probability of breakage of the connection line 9, a wire binder 10 is arranged outside the box body 1, and the connection line 9 passes through the wire binder 10 to connect the interface 7. In order to avoid the influence between the connection lines 9, the wire binder 10 is provided in a plurality of forms, and the plurality of wire binders 10 are arranged at intervals.

[0030] The relay 4 is one or more, in order to realize the OPS function, the relay 4 in the embodiment is seven, which are respectively a starting relay, a preheating relay, a power supply relay, an ECU relay, a hoisting relay, a forward relay and a backward relay, and the plurality of relays 4 are integrated in one electric appliance box, so that different operation modes of the vehicle are realized. The fuse 3 is one or more, specifically, the fuse 3 in the embodiment is eleven, and the relay 4 and the fuse 3 are plugged into the designated positions, that is, the relay slot and the fuse slot.

[0031] In order to provide circuit protection in time, the fuse holder 5 is further arranged in the box body 1 in the embodiment. The fuse holder 5 can quickly cut off the circuit to prevent overcurrent from flowing through the circuit and the equipment, thereby preventing overload and damage of the equipment, and by limiting the current, the fuse holder 5 can effectively prevent fire or other dangerous situations of the circuit, and ensure the safety of the OPS electric appliance box during use. In order to avoid the influence of the fuse holder 5 on other components in the electric appliance box, the OPS circuit board 2 in the embodiment has a mounting position for accommodating the fuse holder 5, specifically, the mounting position has two parts, one part is used for placing the head of the fuse holder 5, that is, the clamping part, and the other part is used for embedding the tail of the fuse holder 5, that is, the end opposite to the clamping part, so as to ensure the stability of the fuse holder 5 during installation and use. The mounting position is arranged close to the corner of the OPS circuit board 2, which is convenient for taking and placing.

[0032] In order to facilitate taking and placing, the box body 1 has a handle 11 on the side, and the handle 11 can be two, which are symmetrically arranged on the two sides of the box body 1. During actual production, the manufacturer can hold the electric appliance box as a whole to prevent the influence of lifting and other actions on the components in the electric appliance box.

[0033] The aforementioned box 1 is also equipped with a detection and control chip, which can provide safety functions such as overcurrent protection, overtemperature protection, battery protection and management, to ensure that the electrical box and connected electrical equipment can respond in a timely manner in abnormal situations, avoiding damage and potential safety risks.

[0034] When the vehicle model requires the OPS function, connect the OPS interface 8 on the integrated OPS electrical box to the corresponding plug on the wiring harness; when the function is not required, replace the OPS electrical box with a traditional electrical box and short-circuit and shield the extra OPS interface 8.

[0035] like Figure 4 The diagram shown is a control principle diagram of the OPS electrical box in this embodiment. By using the OPS electrical box, vehicle starting, preheating, power switching, ECU control, lifting, forward and reverse movements can be realized.

[0036] Example 2: The difference between this example and Example 1 is that: in this example, an integrated OPS electrical box is provided, wherein the OPS interface 8 is pluggable, that is, a slot is formed at the OPS interface 8, and a plug structure that is compatible with the slot is formed at the part to be plugged in, so that quick plugging can be achieved.

[0037] The above embodiment describes an integrated OPS electrical box with an ingenious structure. Based on a traditional electrical box, it integrates the OPS function with the fuse box and relay control circuit required by the traditional electrical box through circuit integration design. This allows it to meet the needs of different types of engines. Since it is an improvement on an existing electrical box, it can meet the OPS function requirements through an additional OPS interface 8. Other plug-in types and pin definitions remain unchanged, giving the OPS electrical box excellent interchangeability to meet different usage needs and reduce usage costs. At the same time, by integrating the OPS function into the existing electrical box, it can also reduce the space occupied by the electrical box.
