Tray body 11 floats through elastic component 22 and connects on the equipment body, and elastic component 22 has head end and tail end along its elastic expansion direction, and the head end is connected with battery tray 1, and the tail end is connected with this body coupling of equipment. Specifically, in the process of taking the battery pack 200 off the electric vehicle 300, the lifting portion drives the installation portion main body and the battery tray 1 to move upwards, after the battery tray 1 contacts the battery pack 200, the battery tray 1 cannot move upwards continuously under the blocking of the battery pack 200, at this time, the unlocking device continues to drive the unlocking piece 21 to move upwards relative to the battery tray 1, and the extending direction of the elastic piece 22 is the same as the floating direction of the battery tray 1, so that when the unlocking piece 21 extends into the battery pack 200, the battery tray 1 can float through the elastic piece 22, the battery tray 1 can be subjected to fine adjustment in the elastic expansion and contraction direction through the elastic piece 22, so that the battery tray 1 can be better attached to the battery pack 200 at the bottom of the electric vehicle 300, and after the battery pack 200 is unlocked, the battery pack 200 can be stably placed on the battery tray 1, and therefore the height of the battery tray 1 can be adjusted according to a chassis of the electric vehicle 300; in addition, in the process of placing the battery pack 200 on the electric vehicle 300, the lifting part drives the installation part main body, the battery tray 1 and the battery pack 200 placed on the battery tray 1 to move upwards, and the battery tray 1 can be finely adjusted in the elastic stretching direction through the elastic piece 22 in the hanging process, so that the battery pack 200 and the locking mechanism 9 on the electric vehicle 300 can be stably hung, the structural form can allow a certain offset error between the placement of the battery pack 200 and the locking mechanism 9, and the accuracy and the stability of hanging the battery are improved.
In particular applications, the elastic member 22 is a spring, and in other embodiments, the elastic member 22 may be a rubber block.
The surface of the tray body 11 departing from the battery pack 200 is provided with a first positioning piece 12, the position of the equipment body corresponding to the first positioning piece 12 is correspondingly provided with a second positioning piece 23, and the head end and the tail end of the elastic piece 22 are respectively sleeved on the first positioning piece 12 and the second positioning piece 23; specifically, one of the first positioning member 12 and the battery tray 1 has a protrusion 122, and the other one opens in the positioning member mounting hole 114 matching with the protrusion 122. In the present embodiment, the first positioning element 12 includes a connecting portion and a protruding portion 122, and the connecting portion has the protruding portion 122, and the battery tray 1 has a positioning element mounting hole 114 matching with the protruding portion 122. With the above structure, the first positioning member 12 is sleeved at the head end of the elastic member 22, so that the head end of the elastic member 22 does not move horizontally relative to the battery tray 1, thereby improving the placing stability of the elastic member 22. In addition, the second positioning part 23 prevents the tail end of the elastic part 22 from generating horizontal displacement relative to the device body, thereby further improving the placing stability of the elastic part 22. With the adoption of the structure, the stability of the battery tray 1 and the battery pack 200 placed on the battery tray 1 is improved through the stability of the elastic member 22, and the battery pack 200 is unlocked and mounted conveniently.
The first positioning member 12 and the second positioning member 23 are kept out of contact within the elastic expansion range of the elastic member 22. Specifically, when the battery pack 200 is placed on the battery tray 1 (the elastic member 22 is pressed due to the gravity of the battery pack 200), or during the process of unlocking the battery pack 200 (the elastic member 22 is further pressed by the battery pack 200 against the bottom of the electric vehicle 300), there is a movement of the battery tray 1 toward the apparatus body. At this time, the first positioning member 12 is also caused to move closer to the second positioning member 23. Because the first positioning piece 12 and the second positioning piece 23 are kept out of contact, the elastic piece 22 has a compression allowance, so that the unlocking piece 21 can fully extend out of the through hole 111 to unlock and position the battery pack 200, and the elastic piece 22 can be elastically deformed all the time by the structural form, thereby avoiding leveling failure.
The second positioning member 23 is fixed to the apparatus body by a connecting member 25 passing through the second positioning member 23 and the apparatus body; the second positioning element 23 is preferably provided with a receiving opening 26 for receiving the connecting element 25. Specifically, the connecting element 25 extends into the device body through the accommodating hole 26, so that the second positioning element 23 can be connected to the device body, and the lower end of the elastic element 22 can be sleeved on the second positioning element 23, so as to connect and limit the elastic element 22. By adopting the above structure, the elastic member 22 is sleeved on the second positioning member 23, so that the lower end of the elastic member 22 does not slide on the surface of the apparatus body in the horizontal direction relative to the apparatus body, the stability of the elastic member 22 is improved, and the elastic member 22 can better provide a buffer for the battery tray 1; in addition, the connecting element 25 penetrates through the second positioning element 23 and the device body to fix the second positioning element 23 on the device body, and since the elastic element 22 is sleeved on the second positioning element 23, the second positioning element 23 is stably fixed, so that the stability of the elastic element 22 is further improved.
At least one positioning part 29 is also arranged on the equipment body. By adopting the structure, the battery pack 200 can be further positioned by the positioning part 29 on the device body, and the stability of the battery pack 200 is improved. Specifically, one end of the positioning member 29 is connected to the apparatus body, the other end of the positioning member 29 extends in a direction close to the battery pack 200, and the positioning member 29 is configured to extend into the battery pack 200 when the battery pack 200 is placed on the battery tray 1, so as to position the battery pack 200. When the battery pack 200 is placed on the battery tray 1, the unlocking member 21 can stretch into the battery pack 200 to unlock and position the battery pack 200, and the positioning member 29 can also stretch into the battery pack 200 to position the battery pack 200, so that the stability of placing the battery pack 200 on the battery tray 1 is further improved. In addition, when the battery pack 200 is unlocked, the positioning member 29 may also extend into the battery pack 200 together with the unlocking member 21, so that the accuracy of positioning the battery pack 200 is improved, thereby achieving stable unlocking of the battery pack 200.
One positioning member 29 is provided, and the distance between one end of the positioning member 29 extending in the direction close to the battery pack 200 and the apparatus body is greater than the distance between one end of the unlocking member 21 extending in the direction close to the battery pack 200 and the apparatus body (i.e., the length of the positioning member 29 is greater than the length of the unlocking member 21). Specifically, when unlocking, the unlocking piece 21 contacts the unlocking mechanism 101 in the battery pack 200, and pushes the unlocking mechanism 101 in the battery pack 200 out of the battery pack 200 to act on the locking mechanism to realize unlocking. In addition, the unlocking member 21 is engaged with the battery pack 200 to achieve the positioning of the battery pack 200 by the unlocking member 21. Therefore, the unlocking member 21 is required to be matched with the unlocking mechanism 101 in the battery pack 200 when extending into the battery pack 200, and the positioning member 29 is required to be arranged in the battery pack 200 when extending into the battery pack 200. By adopting the above structure, when the unlocking piece 21 unlocks the battery pack 200, the contact area between the battery pack 200 and the battery mounting part 28 is realized by matching the positioning piece 29 and the battery pack 200, and the stability of the unlocking battery pack 200 is improved.
The unlocking member 21 includes a positioning portion 211 and a guide portion 212 provided at one end of the positioning portion 211 extending toward the battery pack 200, and: when the battery pack 200 is not placed on the tray body 11, the positioning portion 211 does not protrude on the surface of the tray body 11 on which the battery pack 200 is placed; when the battery pack 200 is placed on the tray body 11, the positioning portions 211 protrude from the surface of the tray body 11 on which the battery pack 200 is placed. Specifically, when the unlocking member 21 extends into the battery pack 200, the guide part 212 on the unlocking member 21 extends into the battery pack 200 first to position the battery pack 200, and then the guide part 212 drives the positioning part 211 to enter the battery pack 200, so that the positioning part 211 can position the battery pack 200. When the battery pack 200 is not placed on the tray body 11, that is, when the battery tray 1 is not used, the positioning portions 211 do not protrude from the surface of the tray body 11 on which the battery pack 200 is placed, thereby preventing the positioning portions 211 from possibly interfering with the placement of the battery pack 200. In addition, the structural form can also improve the service life of the unlocking piece 21. When the battery pack 200 is placed on the tray body 11, the positioning portion 211 protrudes from the surface of the tray body 11 on which the battery pack 200 is placed, so that the positioning portion 211 can be conveniently inserted into the battery pack 200 to position the battery pack 200.
When specifically using, unblock piece 21 is the unblock pole, and the one end and the equipment body of unblock pole are connected, and the other end extends to the one end of keeping away from the equipment body, and the extending direction of preferred unblock pole is perpendicular with the upper surface of equipment body. In order to facilitate the connection of the unlocking lever with the device body, a mounting flange 214 is preferably arranged at one end of the unlocking lever close to the device body, and the unlocking lever is connected with the device body through the mounting flange 214.
The positioning portion 211 and the guide portion 212 may be integrally formed, and the strength of the unlocking member 21 may be improved. Or, the guide part 212 and the positioning part 211 are separately arranged, so that the processing is convenient, and one of the guide part 212 and the positioning part 211 is damaged, so that the positioning part 211 or the guide part 212 can be normally used only by replacing the damaged one. In the present embodiment, the positioning portion 211 and the guide portion 212 are integrally molded.
The surface of the guide portion 212 facing the battery pack 200 has a guide and slide surface 213. By adopting the structure, the insertion of the unlocking piece 21 is convenient, the accuracy of the unlocking piece 21 extending into the battery pack 200 is improved, and even if the position of the battery pack 200 has certain deviation, the deviation can be corrected in the process of placing the battery pack 200 on the battery tray 1; in addition, the sliding guide surface 213 can also ensure that the unlocking member 21 damages the battery pack 200 in the process of inserting the battery pack 200, thereby prolonging the service life of the battery pack 200.
The positioning member 29 may have the same structure as the unlocking member 21.
The battery pack 200 is provided with a predetermined hole matching the unlocking member 21 and the positioning member 29 for both insertion into the battery pack 200. The unlocking member 21 and the positioning member 29 have a certain clearance (e.g., 2-3 mm) from the corresponding predetermined holes, which does not exceed the allowable deviation range of the connection between the battery pack 200 and the cart-end locking mechanism 9, and also ensures that the battery pack 200 can float to a small extent with respect to the battery replacement device when placed on the battery tray 1.
In specific use, the battery replacement device 100 is used for performing battery replacement operation on commercial vehicles such as heavy trucks or light trucks. Further, the battery tray has stronger bearing capacity for the battery pack 200, and the battery replacement device 100 is more suitable for replacing batteries for the counterweight cards.
As will be understood with reference to fig. 8 to 11, the lock mechanism 9 is connected to the electric vehicle 300, and is used to connect the battery pack 200 to the electric vehicle 300. The unlocking mechanism 101 is located inside the battery pack 200.
