Description

Technical fields:

[0001] This utility model belongs to the field of electric vehicle parts technology, and specifically refers to a tail box for electric vehicles. Background technology:

[0002] The tail box of an electric vehicle is a storage compartment installed at the rear of the vehicle. When using an electric vehicle for delivery, items are piled up in the tail box. If the tail box is overcrowded, it is necessary to rummage through the upper layers to retrieve the lower layers, resulting in low efficiency and impacting delivery efficiency. This needs improvement. Summary of the Invention:

[0003] The purpose of this utility model is to provide a tail box for electric vehicles to solve the technical problems mentioned in the background art.

[0004] This utility model is implemented as follows:

[0005] A tail box for an electric vehicle includes a box body and a box cover hinged to the box body. Several pull-out layers are horizontally slidably connected to the box body. The pull-out layers are distributed in a vertical direction and are used for placing objects. Each pull-out layer is provided with a positioning element for positioning the pull-out layer and the box body.

[0006] By adopting the above technical solution, during actual storage, items are placed in corresponding pull-out layers. When they need to be retrieved, the corresponding pull-out layer is pulled out directly without having to search through each layer, which helps to improve retrieval efficiency and further improves delivery efficiency.

[0007] Preferably, the pull-out layer includes a pull-out plate slidably connected to the housing, a pull-out frame disposed on the pull-out plate, and a folding part disposed on the pull-out plate. The pull-out frame and the pull-out plate are spliced ​​together to form a storage space. The folding part is unfolded and laid on top of the pull-out frame to support objects. The folding part is folded to connect several storage spaces.

[0008] By adopting the above technical solution, when there are few items that do not need to be stacked or the number of stacking layers is small, after the bottom layer is filled, the folded part above the items is unfolded and covered on the pull-out frame for fixation. Then, the items are placed on the unfolded folded part, which makes it easy to place the items in the tail box from bottom to top without having to pull out each pull-out layer before placing them, making it convenient to store large items.

[0009] Preferably, the main material of the folding part is a plastic diaphragm. The folding part has several inflation chambers and an inflation port that communicates with the inflation chambers. The inflation chambers expand after being inflated. The box body has a partition cavity containing an air inflator. A plug is provided at the inflation port to seal the inflation port. The folding part has a connecting hook, and the pull-out frame has a hook ring. The connecting hook engages with the hook ring for positioning.

[0010] By adopting the above technical solution, after the folding part needs to be folded, the folding part is unfolded and fixed to the pull-out frame. By injecting gas into the inflation chamber to make the inflation chamber expand, it is beneficial to reduce the shock of the items inside the tail box and improve the support stability of the folding part after it is unfolded.

[0011] Preferably, the inflation chamber is filled with carbon dioxide.

[0012] By adopting the above technical solution, carbon dioxide gas has heat-insulating properties. Injecting carbon dioxide into the inflation chamber increases the support stability of the folded part and also helps to improve the heat-insulating effect of the folded part.

[0013] Preferably, the horizontal cross-section of the box is rectangular, and there are four pull-out plates arranged around the circumference of the box. Each pull-out plate is rotatably connected to a limiting post, which is engaged with the folding part. The pull-out plate is connected to the folding part through the limiting post.

[0014] By adopting the above technical solution, the folding part is connected to the pull-out plate through the limiting post, so that the folding part can rotate relative to the pull-out plate. When delivering large items, there is no need to deflate the air chamber. By rotating several folding parts vertically, several accommodating spaces can be connected, which also helps to improve the heat preservation effect.

[0015] Preferably, the positioning component includes a connecting rod that is slidably connected to the pull-out plate and a plurality of positioning heads disposed on the pull-out plate. The housing has a plurality of positioning holes, which are correspondingly disposed to the positioning heads. The positioning holes are located below the corresponding positioning heads. When the connecting rod moves downward, the positioning head protrudes from the pull-out plate and engages with the corresponding positioning hole. When the connecting rod moves upward, the positioning head disengages from the corresponding positioning hole. A handle is provided at the end of the connecting rod away from the receiving cavity.

[0016] By adopting the above technical solution, when it is necessary to open the pull-out layer to take out an object, the user pulls from bottom to top. The handle drives the connecting rod to move upward, thereby causing the positioning head to disengage from the positioning hole and release the positioning, sending the pull-out layer into the box. When the handle is released, the sliding part descends under the action of gravity, causing the positioning head to lock into the positioning hole, making it convenient to position the pull-out layer.

[0017] Preferably, one end of the positioning head that is inserted into the positioning hole is machined to form an arc-shaped guide surface, and the positioning hole abuts against the arc-shaped guide surface.

[0018] By adopting the above technical solution, the arc surface guides the positioning head during the pulling out and locking process of the pull-out plate, which helps to assist the movement of the positioning head and makes pulling out easier.

[0019] Preferably, the pull-out plate is provided with a spring, which presses against the connecting rod to give the connecting rod a downward tendency.

[0020] By adopting the above technical solution and setting springs, it is beneficial to maintain the stable positioning of the pull-out layer during the operation of the electric vehicle.

[0021] The outstanding advantages of this utility model compared to the prior art are:

[0022] 1. In actual storage, this utility model places the items in corresponding pull-out layers. When they need to be taken out, the corresponding pull-out layer can be pulled out directly without having to check each layer. This helps to improve the retrieval efficiency and further improves the delivery efficiency.

[0023] 2. After the folding part needs to be folded, this utility model unfolds and fixes the folding part to the pull-out frame. By injecting gas into the inflation chamber, the inflation chamber expands, which helps to reduce the shock of the items inside the tail box and improves the support stability of the unfolded folding part.

[0024] 3. The folding part of this utility model is connected to the pull plate through the limiting post, so that the folding part can rotate relative to the pull plate. When delivering large items, there is no need to deflate the air chamber. By rotating several folding parts vertically, several accommodating spaces can be connected, which also helps to improve the heat preservation effect. Attached image description:

[0031] The present invention will be further described below with reference to specific embodiments:

[0032] This application discloses a tail box for an electric vehicle, see [link]. Figure 1 and Figure 2 The device includes a box body 1 and a box cover 2, which are hinged together. The hinge axis of the box body 1 and the box cover 2 is horizontal. The box body 1 is fixed to the electric vehicle frame by welding, quick-release screws, etc. Four pull-out layers 3 are horizontally slidably connected on the box body 1. The four pull-out layers 3 are distributed in the vertical direction and have different heights. Adjacent pull-out layers 3 are spaced apart. The pull-out layers 3 are slidably connected relative to the box body 1. The sliding direction of the pull-out layers 3 is horizontal. The pull-out layers 3 move towards the inside of the box body 1 to store items inside the box body 1, and move away from the inside of the box body 1 to retrieve items.

[0033] See Figure 2 and Figure 3 The pull-out layer 3 includes pull-out plates 31, pull-out frames 32 or folding parts 33. Four pull-out plates 31 are distributed around the circumference of the box body 1. The pull-out frame 32 is located on the side of the pull-out plate 31 close to the inside of the box body 1. The pull-out frame 32 is fixedly connected to the pull-out plate 31. The box body 1 is provided with a sliding groove 11 for the pull-out frame 32 to be inserted. The cross section of the sliding groove 11 in the horizontal direction is "U". The movement of the pull-out plate 31 drives the movement of the pull-out frame 32. The sliding direction of the pull-out frame 32 on the box body 1 is parallel to the distribution direction of the pull-out frame 32 and the connected pull-out plate 31. The pull-out frame 32 and the pull-out plate 31 are spliced ​​together to form a storage space 34. A limit post 311 is rotatably connected to the pull-out plate 31. The rotation axis of the limit post 311 is horizontal and perpendicular to the sliding direction of the pull-out frame 32. The cross section of the limit post 311 in the direction perpendicular to its own rotation axis is circular. There are two limit posts 311 on each pull-out plate 31. The limit posts 311 are inserted into the folding part 33 so that the folding part 33 can rotate around the limit post 311 after it is unfolded.

[0034] See Figure 2 and Figure 3The extension and retraction direction of the folding part 33 is parallel to the sliding direction of the corresponding pull-out plate 31. The main material of the folding part 33 is a plastic membrane. When the folding part 33 is not unfolded, it is rolled up to expose the storage space 34, which facilitates the connection of the storage spaces 34 on several pull-out layers 3 inside the box 1, making it convenient to place large objects. A connecting hook 331 is fixed on the folding part 33, and a hook ring 321 is fixed on the pull-out frame 32. The connecting hook 331 is used to engage with the hook ring 321 after the folding part 33 is unfolded. After the folding part 33 is unfolded, it is fixed to the pull-out frame 32 by the connecting hook 331 and the hook ring 321. Adjacent storage spaces 34 are separated by the folding part 33. In this embodiment, the number of hook rings 321 and connecting hooks 331 on each pull-out layer 3 is 2. In other embodiments, the folding part 33 can be a fabric with an inflatable membrane installed.

[0035] See Figure 1 and Figure 3 The folding section 33 has several inflation chambers 332, which are interconnected. The inflation chambers 332 expand when inflated, increasing the support stability of the folding section 33 when it is unfolded. The gas filled into the inflation chambers 332 is carbon dioxide, which improves the insulation of the tail box.

[0036] See Figure 1 and Figure 3 The folded part 33 has an inflation port 333 that communicates with the inflation chamber 332. A plug 334 is installed at the inflation port 333 to seal the inflation port 333. The plug 334 is inserted into the inflation nozzle and seals the air through elastic deformation. In actual operation, the plug 334 can be pulled out to add or release air into the inflation chamber 332.

[0037] See Figure 1 and Figure 4 The box 1 is also equipped with a compartment 12 for placing an air inflator.

[0038] During delivery, if the delivered item is large, open the plug 334 to deflate the inflation chamber 332. After the inflation chamber 332 deflates, it contracts. After removing the connecting hook 331 from the hook ring 321, roll up the folding part 33 to connect several storage spaces 34.

[0039] If the delivered object is large and needs to be kept warm, remove the connecting hook 331 from the hook ring 321, rotate the folding part 33 to vertical position, so that several storage spaces 34 are connected, and the object is placed between several folding parts 33 to improve the heat preservation effect.

[0040] See Figure 2 and 5A positioning element 4 is installed on the pull-out plate 31, and the pull-out plate 31 is fixed to the housing 1 through the positioning element 4. The positioning element 4 includes a connecting rod 41 and several positioning heads 42. The several positioning heads 42 are located below the connecting rod 41 and are all fixedly connected to the connecting rod 41. The connecting rod 41 and the positioning heads 42 are both connected to the pull-out plate 31 for lifting and sliding. The end of the positioning head 42 away from the connecting rod 41 is machined to form an arc guide surface 421. The housing 1 is provided with positioning holes 13. The position and number of positioning holes 13 correspond one-to-one with the position and number of positioning heads 42. The positioning holes 13 are located below the corresponding positioning heads 42. When the connecting rod 41 moves downward, it causes the end of the positioning head 42 to extend out of the pull-out plate 31 and be inserted into the corresponding positioning hole 13 for positioning. The arc guide surface 421 abuts against the inner wall of the positioning hole 13. A spring 35 is fixed on the pull-out plate 31. The spring 35 is located above the connecting rod 41. The opposite ends of the spring 35, which are distributed parallel to the extension direction, are fixed to the pull-out plate 31 and the connecting rod 41 respectively. The spring 35 presses against the connecting rod 41, so that the connecting rod 41 has a downward tendency, which is beneficial to keep the pull-out layer 3 and the box 1 fixed during the operation of the electric vehicle.

[0041] A handle 411 is fixed to the end of the connecting rod 41 away from the receiving space, making it convenient for the user to move the connecting rod 41.

[0042] The implementation principle of this application is as follows: a pull-out layer 3 is installed on the box 1, and the objects are stacked in layers in each pull-out layer 3. When it is necessary to take out an object, the corresponding pull-out layer 3 is pulled out, which helps to reduce the search time when taking out the object and improves the retrieval efficiency.

[0043] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
