Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
The electric power consumption of the electric truck is large, and therefore a battery pack for driving the electric truck needs a large battery capacity. And the larger the battery capacity, the larger the size of the battery assembly and the heavier the weight. In order to prevent the base from being structurally damaged by the gravity of the heavy battery, it is necessary to increase the strength and rigidity of the base.
In the prior art, a plurality of steel materials (such as i-steel, channel steel and the like) are generally used for welding to form a base frame, and then a guide shaft for guiding and a connector for realizing electrical connection are connected on the frame. However, the prior art has at least the following two problems in application.
On the one hand, the battery of the electric truck is large in size, and accordingly the steel for welding the base is also large in size, and under the condition that the machining method is fixed, the larger the size is, the larger the machining error is, and the relative position between the guide shaft and the connector on the base is larger than the theoretical position error.
On the other hand, in the process of welding the base frame by using steel, the errors between the size and shape of the welded frame and the theoretical size and shape are large due to welding deformation and the like, and the errors between the relative position between the guide shaft on the base and the connector and the theoretical position are also large.
When the position error between the guide shaft and the connector is large, the connector on the battery assembly and the connector on the base cannot be aligned in the process of mounting the battery assembly on the base.
In view of this, the present application provides a power supply device and a vehicle that connect the guide and the connector of the base to one mounting plate and correspondingly connect the guide and the connector of the battery pack to the other mounting plate. Compared with the method that the guide piece and the connector are connected to the frame formed by welding, the guide piece and the connector are connected to the mounting plate, the problem that errors caused in the steel welding process are large can be solved, and the two connectors are aligned more easily.
The following describes the power supply device and the vehicle provided by the present application in detail with reference to the drawings. The power supply device may be applied to any electric vehicle that can improve endurance by replacing a battery, and for convenience of description, the following description will be given by taking an electric truck as an example.
Fig. 1 is a schematic diagram of an embodiment of a power supply apparatus provided in the present application, and as shown in fig. 1, the power supply apparatus provided in the present application includes a base 200 and a battery assembly 100 detachably mounted on the base 200. The cradle 200 is attached to the electric truck for connecting and supporting the battery assembly 100. The battery assembly 100 stores electric power therein, and the battery assembly 100 is mounted on the base 200 to supply electric power to the electric truck through the base 200.
Illustratively, the base 200 is connected to the rear of the cab or both the left and right sides of the main longitudinal member of the vehicle by a connection assembly 260, and when replacing the battery pack 100, the battery pack 100 is lifted by a crane, a forklift, or the like, and attached to the base 200 with the assistance of an operator.
The base 200 is provided with a first connector 230, and the first connector 230 is electrically connected with a driving motor of the electric truck. The battery assembly 100 is provided with a second connector 130, and the second connector 130 is electrically connected to an energy storage unit (e.g., a battery pack) inside the battery assembly 100. When the battery assembly 100 is mounted on the base 200, the first connector 230 and the second connector 130 are engaged and electrically connected, so that the electric power stored in the battery assembly 100 is supplied to the driving motor to drive the electric truck to move.
The base 200 is provided with a first guide 220, and the battery assembly 100 is correspondingly provided with a second guide 120. The first guide 220 and the second guide 120 cooperate to guide the relative position between the battery assembly 100 and the base 200 during the mounting of the battery assembly 100 to the base 200, thereby aligning the first connector 230 and the second connector 130.
The first guide 220 and the second guide 120 are not limited in structure, and can be guided during the installation of the battery assembly 100 to the base 200, so as to guide the relative position between the battery assembly 100 and the base 200.
The base 200 further includes a first mounting plate 210, and a first guide 220 and a first connector 230 are coupled to the first mounting plate 210. The battery pack 100 further includes a second mounting plate 110 opposite to the first mounting plate 210, and the second guide 120 and the second connector 130 are coupled to the second mounting plate 110.
The first mounting plate 210 and the second mounting plate 110 are plate-shaped members of an integrated structure, and are different from a frame formed by welding a plurality of steel materials in the prior art. That is, the first mounting plate 210 and the second mounting plate 110 are not deformed and have different sizes due to the connection between the plurality of members in the prior art during the process of manufacturing the base 200 and the battery pack 100.
For example, the first mounting plate 210 and the second mounting plate 110 may be integrally formed plate-shaped members. For example, the first mounting plate 210 and the second mounting plate 110 are rolled steel plates.
In the power supply device provided by the present application, the base 200 includes the first guide 220 and the first connector 230, and the first guide 220 and the first connector 230 are mounted on the first mounting plate 210. Compared to the prior art in which the guide and the connector are connected to the frame formed by welding a plurality of steel materials, the first mounting plate 210 and the second mounting plate 110 are not deformed or have different sizes due to the connection between the plurality of members, and therefore, after the first guide 220 and the first connector 230 are connected to the first mounting plate 210, the error in the relative position between the first guide 220 and the first connector 230 is smaller. Accordingly, the second guide 120 and the second connector 130 are coupled to the second mounting plate 110, so that an error in the relative position between the second guide 120 and the second connector 130 is smaller. Therefore, after the first guide 220 and the second guide 120 are fitted, an error between the first connector 230 and the second connector 130 is smaller, i.e., alignment is easier.
Optionally, the base 200 further comprises a base frame 240, the first mounting plate 210 being connected to the base frame 240; the battery assembly 100 further includes a battery assembly frame 140, and the second mounting plate 110 is coupled to the battery assembly frame 140. Since the battery of the electric truck is heavy, the first mounting plate 210 and the second mounting plate 110 are coupled to the frame, and the first mounting plate 210 and the second mounting plate 110 are prevented from being deformed by the weight of the battery assembly 100.
Illustratively, the base frame 240 and the battery pack frame 140 may be welded from a plurality of steel materials. For example, a plurality of channel steel or I-steel are welded. The cost is reduced while the structural strength is ensured.
Optionally, the base 200 further comprises a third guide 250 connected to the base frame 240, the battery assembly 100 further comprises a fourth guide 150 connected to the battery assembly frame 140, and the third guide 250 and the fourth guide 150 are matched with a lower precision than the first guide 220 and the second guide 120.
In one aspect, the first guide 220 and the second guide 120 serve to align the first connector 230 and the second connector 130, and since the mating accuracy of the connectors is high, the mating accuracy of the first guide 220 and the second guide 120 is relatively high. On the other hand, when the fitting accuracy of the first guide 220 and the second guide 120 is high due to the heavy weight and the inconvenient operation of the battery assembly 100, it is not easy to align the first guide 220 and the second guide 120. Therefore, the power supply apparatus is provided with the third guide 250 and the fourth guide 150 having low fitting accuracy, and in the process of mounting the battery pack 100, the third guide 250 and the fourth guide 150 are first fitted to guide the relative position between the battery pack 100 and the chassis 200, thereby enabling the first guide 220 and the second guide 120 to be smoothly fitted.
The third guide 250 and the fourth guide 150 are not limited in structure, and can guide the battery assembly 100 during the installation process of the base 200, so as to guide the relative position between the battery assembly 100 and the base 200.
Illustratively, the third guide 250 includes guide posts, and the base 200 includes a rectangular base frame 240, one guide post being disposed at each corner of the base frame 240. The battery assembly 100 also includes a rectangular battery assembly frame 140, with a friction plate disposed inwardly of each corner of the battery assembly frame 140. When the battery pack 100 and the base 200 are connected, the guide posts extend through the area bounded by the battery pack frame 140 and engage the friction plate.
Alternatively, the number of the first guides 220 is plural, and the plural first guides 220 are disposed around the first connector 230; accordingly, the number of the second guide 120 is plural, and the plural second guides 120 are disposed around the second connector 130. The third guide 250 is located on a side of the first guide 220 away from the first connector 230, and correspondingly the fourth guide 150 is located on a side of the second guide 120 away from the second connector 130.
Under the premise of the same processing method, the larger the length or the distance is, the larger the processing error is. Therefore, the first guide 220 requiring higher fitting accuracy is disposed close to the first connector 230, and the third guide 250 requiring lower fitting accuracy is disposed away from the first connector 230. Also, the first connector 230 is generally disposed at a position near the center of the base 200, which makes it possible to bring the third guide 250 closer to the edge of the base 200, thereby making it easier to observe the position of the third guide 250 when mounting the battery assembly 100, and smoothly fitting the third guide 250 and the fourth guide 150.
Optionally, a fifth guide 231 is disposed on the first connector 230, a sixth guide 131 is disposed on the second connector 130, the fifth guide 231 and the sixth guide 131 are matched, and the matching precision of the fifth guide 231 and the sixth guide 131 is greater than the matching precision of the first guide 220 and the second guide 120. The fifth guide 231 and the sixth guide 131 provide a high mating accuracy, which can improve the accuracy of the alignment of the first connector 230 and the second connector 130.
Illustratively, the fifth guide 231 is connected with the housing of the first connector 230 as an integral structure, and the sixth guide 131 is connected with the housing of the second connector 130 as an integral structure. This can further improve the accuracy of the fit between the fifth guide 231 and the sixth guide 131. For example, the fifth guide 231 and the first connector 230 are injection molded as an integral structure through an injection molding process, and the sixth guide 131 and the second connector 130 are injection molded as an integral structure.
Optionally, the first mounting plate 210 and the second mounting plate 110 are identical in construction and size.
Illustratively, the first mounting plate 210 and the second mounting plate 110 are the same mounting plate, and guide mounting holes and connector mounting holes are formed on the mounting plate, the guide mounting holes are used for connecting the first guide 220 and the second guide 120, and the connector mounting holes are used for connecting the first connector 230 and the second connector 130.
The first mounting plate 210 and the second mounting plate 110 have the same structure and size, so that the error between the first mounting plate 210 and the second mounting plate 110 can be reduced by processing the same processing method or processing line, that is, the position error between the first connector 230 and the second connector 130 after the first guide 220 and the second guide 120 are matched is reduced.
Alternatively, the first guide member 220 includes a guide shaft, and the second guide member 120 includes a guide ring, and the guide shaft is inserted into the guide ring. Since the base 200 is generally installed in a place where the battery assembly 100 is located above the base 200, the first guide 220 includes a guide shaft, which facilitates viewing of the position and state of the guide shaft when the battery assembly 100 is installed.
Optionally, the power supply device further comprises a clamping member 170 disposed on the frame of the battery assembly 100, and a clamping mechanism 271 and a driving mechanism 272 disposed on the frame of the base 200,
the driving mechanism 272 is movably connected to the engaging mechanism 271, and the driving mechanism 272 is configured to drive the engaging mechanism 271 to move toward the engaging member 170 when the battery assembly 100 is mounted on the base 200, so that the engaging mechanism 271 is engaged with the engaging member 170, thereby blocking the battery assembly 100 from being separated from the base 200.
Optionally, a buffer is provided between the chassis 200 frame and the battery assembly 100 frame. Illustratively, the cushioning member includes a plurality of rubber pads evenly disposed around to cushion the impact between the battery assembly 100 and the base 200. Of course, the buffer member may be other components such as a spring, a hydraulic buffer member, etc.
In a second aspect, the present application provides a vehicle including a power supply apparatus.
The application provides a vehicle, base include first guide and first connector, and first guide and first connector install on first mounting panel. Compared with the prior art that the guide piece and the connector are connected on a frame formed by welding a plurality of steel materials, the first mounting plate and the second mounting plate are free from deformation and size difference caused by connection among the plurality of pieces, so that after the first guide piece and the first connector are connected on the first mounting plate, the error of the relative position between the first guide piece and the first connector is smaller. Accordingly, the second guide and the second connector are attached to the second mounting plate, making the error in the relative position between the second guide and the second connector smaller. Therefore, after the first guide and the second guide are fitted, the error between the first connector and the second connector is smaller, i.e., alignment is easier.
